A powder material transport vehicle

Abstract

The invention discloses a powder and particle material transport vehicle which comprises an automobile chassis, a tank, an air compressor and an unloading control system, wherein fluidized beds which are arranged in a centralized way towards the center layer by layer are adopted as a plurality of branch bins of the tank; the powder and particle material transport vehicle has the structure that a plurality of layers of main guide plates which are gradually lowered towards the center are symmetrically arranged at the two sides of the length direction of each branch bin by taking a discharge hole as the center; diversion air holes are respectively arranged between air chambers under the plurality of layers of main guide plates and the main guide plates; the direction of the air flow of the diversion air holes are set towards the discharge hole; an air flow hole is formed in a clapboard between each air chamber and each diversion air hole; two side guide plates are symmetrically arranged at the two sides of each branch bin; the lower part of each side guide plate is provided with a lower layer diversion air hole; the direction of the air flow of the main guide plate and the side guide plate at the bottommost layer is set towards the center of the discharge hole, so that a rectangular region can be formed; particles or powder can be blown to the discharge hole and is collided with the air flow which is blown head-on, so that the residual material in the tank can be thoroughly removed. The powder and particle material transport vehicle is suitable for bulk grain particles and bulk cement powder.

Description

technical field [0001] The invention relates to a powder material transport vehicle suitable for bulk grain particles and bulk cement powder. Background technique [0002] Powder material transport vehicle is also called bulk cement vehicle, which is composed of special vehicle chassis, bulk cement vehicle tank body, gas pipeline system, automatic unloading device and other parts. It is suitable for bulk transportation of fly ash, cement, lime powder, ore powder, granular alkali, and other powdery dry materials. It is mainly used in cement plants, cement warehouses, large construction sites and bulk grain transportation, which can save a lot of packaging materials and loading and unloading labor. [0003] The tank body of the powder material truck is mainly composed of a tank body, a feed inlet, a fluidized bed, a discharge pipe, an air intake pipe and other accessories. There are two or three feeding ports on the top of the tank. The front and rear air chambers of the po...

AI Technical Summary

Problems solved by technology

The lower parts of all deflectors form an integral air chamber. The air flow through the fluidized cloth basically acts upwards. The material collapses to a certain extent and forms a depression around the outlet. When the upper part of the fluidized cloth is exposed to the air flow and accelerates, the fluidized cloth Because the bottom is overlaid by materials and the air volume is reduced or airtight, a ring-shaped mountain-shaped backlog will be formed around the discharge port, and the airflow will form a circulation and turn over the ring-shaped mountain-shaped backlog, and it will be discharged from the concave part from the discharge port, forming an empty load, causing the tank to The remaining material in the body cannot be discharged, which is the fatal defect of the fluidized cloth fluidized bed; the void space is below the deflector, which occupies a large effective volume and raises the center of gravity; When solidifiable matter (such as: cement) will solidify, blocking the pores will affect the fluidization speed; after a long period of observation, the remaining material that cannot be discharged around each outlet is about 200 kg. more material

[0007] 3. The cone-type powder material transport vehicle, the cone-type bucket occupies a lot of space, the effective volume is reduced, and the center of gravity of the tank is increased; the structure of the tank is too complicated, the production is difficult, and the production cost is high.

[0008] 4. The front top dumping type is not much different from a dump truck. To achieve long-distance and high-altitude excretion, external power is needed. The production cost and difficulty of dual power are very high.

[0010] The above-mentioned types of vehicles have a certain selectivity for particles or powders, and cannot realize the advantage of one vehicle with multiple uses, or the structure is complex, or the discharge is not complete. These defects have always plagued manufacturers and users.
