Working characteristics of powder tank semi-trailer

1. About the powder tanker

The powder tank truck is suitable for bulk transportation and pneumatic unloading of non-flammable, non-explosive, non-toxic and non-corrosive powder dry materials such as fly ash, cement, lime powder cement special cement, etc. It is widely used in industry, agriculture, commerce, power plants and construction.

2. Product structure:

The tank semi-trailer is mainly composed of tank body, frame, power system (diesel engine air compressor) side and rear protection, electrical circuit system, walking structure, traction pin, walking platform, climbing ladder, manhole cover, unloading system, etc. The whole vehicle is mainly composed of chassis, tank body, power system (power take-off, drive shaft, air compressor), electrical circuit system, walking platform, climbing ladder, manhole cover, unloading system, etc.

2. Working principle: use its own engine or borrow the engine of the main vehicle to drive the vehicle-mounted air compressor through the power take-off drive shaft or pulley, and send the compressed air into the air chamber of the sealed tank through the pipeline, so that the powder particles on the fluidized bed The material is suspended in a fluid state. When the pressure in the tank reaches the rated working pressure, the discharge butterfly valve is opened, and the powder material is discharged through the discharge system.

3. Product features: Sealed transportation can effectively avoid cargo scattering and environmental pollution. It has the characteristics of short transportation cycle, high efficiency and low cost. The company's products use advanced three-dimensional design software to optimize the design of the tank body structure. The light vehicle uses high-strength steel, which improves the reliability of the product and reduces the weight of the body; the tank body adopts a fully automatic longitudinal and circumferential welding process, and the weld seam is firm , Beautiful: The whole vehicle is shot blasted to improve the strength of the whole vehicle and the adhesion of the paint, so as to prevent the occurrence of rust and paint peeling off. The vehicle accessories adopt well-known brands at home and abroad to provide customers with more stable quality and lighter weight. , Operation more convenient transportation equipment.

3. Product-specific assembly and its working principle

The main assembly of the powder tank truck is composed of tank body, power system (diesel engine or power take-off, air compressor), air system, braking system and other parts. 1. Tank body: The tank body is mainly composed of two inclined cone tubes and front and rear heads, which are placed on the frame and serve as a carrier. The tank body is equipped with a material inlet (manhole), a non-slip walking platform and a ladder for loading and maintenance personnel to enter the tank. Inside the tank, there are slide plates (a part of the tank body), air chambers, fluidized beds composed of perforated plates (or special canvas), discharge ports, reinforcing ribs, etc., and the tank body structure is V-shaped, W-shaped or simple. .

2. Power system: Oil-free swing-rod single-cylinder or double-cylinder air compressors of well-known domestic brands are used to provide compressed air for unloading. The rated working pressure is 0.2Mpa; the displacement is 10-14 cubic/min. The diesel engine and electric motor are connected to the transmission shaft through the secondary forcer to provide power input for the air compressor.

4. Other structural assemblies of the product and their working principles

1. Frame: The frame is the main body of the powder tank truck. It is welded into a frame structure by two longitudinal beams and multiple cross beams, and is formed by welding with the tank body. Since the frame is the main body of the semi-trailer, no welding or drilling operations can be performed at any position on the longitudinal beam without the consent of our company!

2. Running mechanism system: The running mechanism system is composed of suspension, leaf spring, pull rod, axle and wheels, etc. The suspension is a three-axis series balanced leaf spring suspension (air suspension can also be used), which is used to support the load , and has the effect of absorbing driving vibration.

3. Brake and its operating device: This series of semi-trailers adopts a double-pipeline pneumatic braking system. The service brake system mainly consists of palm joints, air supply pipelines, control pipelines, emergency maintenance valves, gas storage tanks, energy storage brake chambers and wheel brakes.

4. The parking brake is controlled by the energy storage spring braking system of the semi-trailer, and the wheel brake is also used as a parking brake. This device is used when parking or parking on a slope.

5. ABS braking system: It is an electronic system that controls and monitors the vehicle speed during braking. It can improve the active safety of the vehicle.

6. The trailers produced by our company are generally equipped with 90# or 50# traction pins without special instructions. When the vehicle is in use, the traction pin and traction plate should be lubricated with lithium-based grease.
