Bulk cement trailer

Bulk cement trailer product overview:

Bulk cement trailer, full name of Bulk cement trailer, it is suitable for fly ash, cement, lime powder, ore powder, alkali particles and other particles diameter is not greater than 0.1mm powder dry material bulk transport. Powder material carrier is a special purpose vehicle widely used in industry, agriculture, commerce, power plant, construction, etc.

The advantages of Bulk cement trailer

1. Reduce manpower consumption, improve labor productivity and improve working conditions;
2. Save the cost of raw materials, paper bag packaging and crushing, and reduce the transportation cost;
3. Cement loss is reduced, the loss rate is generally below 0.5 percent, while bag loss rate is greater than this ratio;
4. Ensure the quality of cement. Bulk cement trailer is not easy to be affected by moisture during transportation and seldom deteriorates when stored for a year.
5. Reduce environmental pollution;

Bulk cement trailer product structure and working principle

1. Product structure Bulk cement trailer chassis and powder bulk transport special device consists of two parts;
2. The installation part mainly includes transmission system, tank, pipeline system, auxiliary device, auxiliary beam four parts;
3. The working principle of the Bulk cement trailer, the Bulk cement trailer engine power by taking power, drive shaft and other mobile devices to air compressors, compressed air into the Bulk cement trailer produced by air compressor, after liquefaction, the liquefaction plant powder material for tank inside and outside differential pressure, powder materials along with the air discharge pipe to the specified location;

Introduction to fluidization of Bulk cement trailer

When the gas from the lower part of the container into the powder layer, if the gas velocity exceeds a certain value (cement of 0.015 m/s), gas and powder granule of the friction force equals the weight of powder, granule, powder, granule no longer rely on the fluidized bed, this time they can move freely, flow from high to low, make the powder layer on the surface level, similar to the nature of the liquid. If there is a hole in the side wall of the container, the powder can also be ejected from the hole. This is called fluidization. Bulk cement trailer is the use of powder fluidization characteristics to achieve unloading. Fluidization cloth in which the role is to compress the air to form a fine, uniform air flow into the powder layer, the powder fluidization;

1. The Bulk cement trailer tank is mainly composed of head, cylinder, manhole cover and liquefaction device, etc.;
A. Standard ellipse head is used for head, and the main specifications are EH2300, EH2400, EH2500, EH2600, EH2700mm. B Head and cylinder materials are Q345, QST420, 610, etc.
B. Manhole cover adopts two kinds of structure, one is the inner button type manhole cover (after loading the vehicle height is 100mm lower than the external pressure spring lifting structure, but the operation is poor, the operation is difficult), one is the outer three-jaw external pressure manhole cover (high height, good operation mobility, easy operation), the standard configuration is the inner button type manhole cover.
C. The internal fluidization device is the core component of the Bulk cement trailer, which is mainly composed of canvas liquefaction device (composed of porous plate, side slide plate, and the supporting structure below. The porous plate and side slide plate are at a certain Angle with the horizontal plane. In order to improve the effect of liquefaction, a ridge plate is added to the porous plate for diverting Bulk cement trailer and increasing gas flow rate. The liquefied cloth is pressed on the porous plate with bolts, and a closed air chamber is formed under the fluidization cloth. The air chambers of each compartment are not connected, and the front and rear compartments can be discharged independently) and the breathable belt type liquefaction device;

Transmission System

mainly including the force, drive shaft, air compressor (rated working pressure of 0.2mpa, speed of 800-1100r/min) and other components; A magnetoelectric tachometer is installed outside the tank to monitor the speed of the air compressor. The engine throttle size can be adjusted by adjusting the throttle controller, so as to change the speed of the air compressor.

Pipeline system

mainly including the force, drive shaft, air compressor (rated working pressure of 0.2mpa, speed of 800-1100r/min) and other components; A magnetoelectric tachometer is installed outside the tank to monitor the speed of the air compressor. The engine throttle size can be adjusted by adjusting the throttle controller, so as to change the speed of the air compressor.
6. Pipeline system: aPipeline system

discharge pipeline is mainly composed of suction port, butterfly valve (sealed by rubber seal ring, such as damage can be replaced), discharge steel pipe, discharge pipe joint, discharge hose (wear-resistant steel wire discharge hose, diameter of 102mm); A shockproof pressure gauge is installed above the tank body to monitor the pressure changes in the tank to guide unloading;
According to QC/T560-1999 “Technical Conditions of Bulk cement trailer” requirements: in the vertical height of 15m, horizontal distance of 5m, working pressure of 0.2mpa conditions, the average unloading speed of cement truck is not less than 1.2t/min, residual rate is not more than 3%
