Powder material semi-trailer structure
â— The powder material semi-trailer powder material transport semi-trailer is a special vehicle for large-volume dust material (bulk cement) transportation. It is generally suitable for areas where the weight-based charging is strictly in accordance with national regulations. The volume is generally between 35-45 square meters. .
Introduce
Suitable for fly ash, cement, lime powder, ore powder and other particles with diameter of not more than 0.1mm dry material transport and pneumatic discharge, when the vertical height of discharge reaches 15m, the level can also reach a distance of 5m.
The semi-trailer transporter uses its own engine power to drive the on-board air compressor through the power take-off device, and sends the compressed air into the air chamber in the lower part of the sealed tank through the pipeline, so that the cement in the fluidized bed can be suspended into a flow state. When the pressure in the tank reaches the rated value, the discharge butterfly valve is opened, and the fluidized cement flows through the pipeline for transportation.
The use of domestic advanced technology, innovative design, durable. The air bag type has a large carrying capacity, and the discharging speed is fast and the residual quantity is small. The one-piece synthetic tank has the characteristics of high overall strength, good rigidity, good pressure resistance, and good performance.
The design of the fluidized bed in the tank is scientific and reasonable in layout. It can effectively shorten the discharge time to 1.4 T/min, improve the volumetric utilization of the tank, and reduce the residual ash rate. The remaining ash rate is 0.2%. The powder material transporter tank body adopts a double-cone introverting horizontal structure, double-pipe inlet and double-barrel feeding, and its discharging speed and remaining rate are in line with industry standards.
Features 1. Frame and traction pins: The frame is a space frame type low alloy steel welding structure. The frame is welded by two T-shaped longitudinal beams and cross beams to support the load. Below the front of the frame is a tractor pin and traction pin plate attached to the tractor, size 90. Traction pins are assembled for easy replacement. An air brake connector and a wire connection socket are mounted on the front cross member of the frame. Front and rear sides of the frame are equipped with lighting or signaling devices.
2. Suspension system: The lower beam of the stringer is supported by a suspension device, and the lower beam is supported by the support device. The suspension system is a three-axis leaf spring suspension suspension, which is used to support the load and absorb the vibration of the vehicle. The leaf spring suspension system is fastened to the axle body with U-bolts.
The parking brake is controlled by a spring-loaded spring brake system and the wheel brake doubles as a parking brake. Use this device when parking or standing.
3. Axles and wheels: Three suspension axles are equipped with the same axle assembly. The axle is a square tube axle, and the axle body is provided with a platform for mounting a leaf spring suspension and a bracket for installing a brake air chamber. The shaft head is used to install wheels, hubs and brakes.
4. Supporting device: In order to reliably park the semi-trailer after it is separated from the index car, two support devices are provided on the front end of the frame for left-right linkage or left-right single action. It is composed of a screw transmission mechanism, a bevel gear transmission mechanism, a two-speed gear box, a transmission rod, an operating handle, and the like. When the handle is pushed in, it can be rotated at a high speed, and when the handle is pulled out, it can be rotated at a low speed. When the pedestal is in contact with the ground, you can only use the low-speed lifting.
5. Brake and its operating device: The semi-trailer adopts dual-pipe inflating braking system and is equipped with anti-lock braking system (ABS).
6. Electrical system: The semi-trailer is equipped with an internationally applicable electrical system adapted to the tractor. There is an electrical connector socket on the front frame of the frame. Braking lights, turn signals, parking lights, reversing lights, license plate lights, fog lamps and triangular reflectors are provided at the rear of the frame. Front and side lights, side marker lights and front right are provided on the front and both sides. With ABS indicator. Various lighting voltages are 24V DC.
7. The tank body is an all-metal weldment, and the tank body is a vessel filled with material by welding with a common carbon structural steel plate and a stamped head.
