Advantages of pneumatic conveying system

The pneumatic conveying system is mainly divided into dense phase pneumatic conveying system and dilute phase pneumatic conveying system, and has the following advantages:

1. The pneumatic conveyor conveyed materials can be bulk, the high control efficiency, and the low cost of packaging and handling;

2. The pneumatic conveying equipment is simplified, the small occupied space, the area can be fully utilized, and the investment and maintenance costs of the machine equipment are low;

3. Long conveying distance, large conveying range, less control staff, and automatic control; therefore, less labor is required;

4. The pneumatic conveyor conveying pipe can be flexibly arranged, so that the configuration of the factory is reasonable;

5. The pneumatic conveyor conveyed materials will not be restricted by the weather and the surrounding environmental conditions of the pipeline, and the layout of the production workshop is relatively simple;

6. Pneumatic conveyor can prevent the material from being damp, fouled or mixed with other debris, and can guarantee the product quality of the material;

7. Many kinds of technological operations can be carried out in the transportation stage, such as mixing, crushing, classification, drying, cooling, dust removal and other chemical reactions;

8. Pneumatic conveyor is possible to carry out long-distance control from several points to one place, or from one place to several points;

9. Relative to chemically unstable materials, inert gas can be used for transportation.

Although, compared with other conveying types, the disadvantage of pneumatic conveyor is that the power consumption is large, the power consumption of the dilute phase pneumatic conveying is 2-4 times that of the bucket elevator, and 15-40 times that of the belt conveyor. Moreover, the closer of the transmission distance, the more significant this situation.

The new developed dense phase pneumatic conveying method has now overcome the above-mentioned shortcomings of large power consumption. The advantages of pneumatic conveying are more prominent in various continuous conveyors. Even the dilute phase pneumatic conveying system is superior to other conveyors except for the wear of parts and large power consumption. The power consumption of the dense phase pneumatic conveying system has been greatly reduced to only higher than the belt conveyor, and the wear of the parts is not significant. It is precisely that pneumatic conveying has the above-mentioned advantages, so its application is increasingly widespread.

What Is a Screw Conveyor?

A screw conveyor or auger conveyor is a device that makes use of a revolving helical screw, called "flighting", that is set up within a tube or trough, to relocate liquid or granular products. They are utilized in several bulk handling industries. Screw conveyors in modern-day sector are frequently made use of horizontally or at a slight slope as a reliable method to relocate semi-solid materials, including food waste, wood chips, aggregates, grain grains, pet feed, central heating boiler ash, meat and also bone dish, municipal strong waste, and also numerous others. The first kind of screw conveyor was the Archimedes' screw, utilized given that ancient times to pump irrigation water.

They generally contain a trough or tube containing either a spiral blade curled around a shaft, driven at one end as well as held at the various other called a strong shaft screw. Other types are open helix or shaftless screws driven at one end and totally free at the other. The price of quantity transfer is symmetrical to the rotation rate of the shaft. In industrial control applications the gadget is often made use of as a variable rate feederby varying the rotation price of the shaft to provide a measured price or quantity of product into a procedure.

When space permits, utilizing an inclined screw conveyor is an extremely cost-effective technique of raising as well as sharing materials. As the angle of inclination increases, the capability of a given unit swiftly lowers. The basic rule of thumb is 45 degrees or much less, or else the product will certainly wind up falling in reverse over the flighting and also not communicating to the intended location.

Requirements and selection requirements

Below is the essential information to bring to a distributor when specifying the right screw conveyor for the job. Note that this section only outlines the significant requirements, yet even more exist.

Screw conveyor ability

Calculate the quantity per hour required to be conveyed; this can be done by discovering the desired cubic feet per hour, selecting the advised trough loading percent for the conveyor, choosing the appropriate screw diameter, as well as identifying the conveyor drive RPM. The maximum advised ability is commonly given with each screw size and also is additionally impacted by the kind as well as size of pitches, in addition to the product being delivered. Your provider will certainly probably have tables that will certainly help determine this ability and also is the very best source of information.

Screw style & drive

There are many sort of screw layouts, each with their own benefits. Certain kinds, such as the paddled screw, are used to ensure added blending happens, while the short pitch screw is frequently utilized for incline conveyers to preserve effectiveness. Determine the screw layout by the desired function of the screw conveyor and select from the offered options. Likewise, the screw style is pertinent to the drive, as there have to be enough horse power to pull material with the auger. Obtaining the right drive for the preferred screw form will aid ensure it works as planned.

Load type, trough load, and also trough design

What will be going through the conveyor? Depending upon the material, there are choices to select from that will assist make communicating it easier. As an example, If the product is light, completely dry, and unsafe, take into consideration a secured, rounded trough that will supply high dust protection and also regulated circulation. Similarly, if the product is naturally non-flowing, consider a lower trough tons percentage and a shaftless screw kind. The shape of the trough will influence the conveyor capacity, so figure out which trough design will certainly align best with the preferred flow price.

Actions, control, as well as setting

Ultimately, think about the outside elements and also actions of the screw conveyor in your application. How much distance must be covered? Will it be increasing/decreasing in altitude, as well as will the worldly need to be separated from operators/the atmosphere? Additionally, will the conveyor run at an established speed, or will a variable rate drive be used to change the rate? Will the conveyor be part of a larger control system, as well as will sensors need to be installed to guarantee precision? Addressing these questions will certainly permit you to tighten your search criteria as well as locate one of the most efficient screw conveyor for your application.

Precautions For Construction Of Concrete Pump

 Concrete conveying pump, also known as concrete pump, is composed of pump body and conveying pipe. It is a machine that uses pressure to continuously transport concrete along a pipeline. It is mainly used in housing construction, bridge and tunnel construction, and is a common equipment for construction sites. So what are the precautions for concrete pump construction?

1. First of all, sand and gravel particle size, cement number and mix ratio should meet the requirements of the pump's mechanical performance according to the factory instructions.

2. The parking brake and the locking brake of the pumping equipment should be used at the same time, the tires should be wedge tight, the water supply should be normal and the water tank should be filled with clean water, there should be no debris in the hopper, and the lubrication points should be lubricated normally. All bolts of pumping equipment should be tightened, pipe joints should be tightly sealed, and protective devices should be complete and reliable.

3. Check the control beginning of each part, and adjust the handle, hand wheel, control rod, cock, etc. should be in the correct position. The hydraulic system should be normal without leakage.

4. Prepare cleaning tubes, cleaning supplies and other related devices. Before operation, the pipeline must be lubricated with cement mortar prepared according to the regulations. Irrelevant personnel must leave the pipeline.

5. The outriggers should be fully extended and firmly supported. Do not start the boom before being fixed. The placing boom can only rotate after raising the support. The spreading boom should be carried out in order. It is strictly forbidden to use the boom to lift or drag objects. When the placing boom is in the fully extended state, it is strictly forbidden to move the body. When moving during operation, the upper boom should be folded and fixed, and the moving speed should not exceed 10km/h. The placing boom shall not use piping with a diameter exceeding the specified diameter, and the connected wheel pipe shall be secured with an anti-drop safety rope.

6. Various instruments and indicators should be monitored at any time, and if abnormalities are found, adjust or deal with them in time. If the conveying pipe is blocked, reverse operation should be performed to return the concrete to the hopper, and the pipe should be removed if necessary to remove the blockage.

7. When the pumping system is under pressure, do not open any delivery pipes and hydraulic pipes. The safety valve of the hydraulic system shall not be adjusted arbitrarily. The accumulator can only be filled with ammonia gas.

8. After the operation, all the concrete in the hopper and pipeline must be output, and then the pump, hopper and pipeline must be cleaned. When flushing the pipeline with compressed air, no people should stand within 10m in front of the outlet end of the pipeline, and metal mesh baskets should be used to collect the washed out foam rubber and sand. It is strictly forbidden to use compressed air to flush the placing boom piping. The folding and shrinking of the boom must be carried out in order. All parts of the control switch, adjustment handle, hand wheel, control rod, cock, etc. should be reset and the hydraulic system should be unloaded.
