Draught fan for truck bed of off-gas heating dumper

Abstract

The invention provides a draught fan for truck bed of off-gas heating dumper, wherein the bottom and the lateral surface of a truck bed are designed into dual-layer structures, the bottom of the truck bed is retained with an air inlet, which can collect off gas discharged by an automobile engine, a partition plate is provided between each dual-layer structure of the truck bed for supporting, small holes are opened on each partition plate, then the inner parts of the dual-layer structures of the bed truck are communicated with each other via the small holes; a baffle with one end being opened is provided on the bottom of the dual-layer bed truck horizontally, after off gas which is high in temperature is collected into the dual-layer structure via a gas collector, the off gas is dispersed evenly via the small holes, a heat circulating system is formed in the inner part, after heat balance is reached, a natural heat insulation box is formed, the whole temperature of the truck bed is risen to a certain level, which does not freeze with materials and achieves normal working. The off gas with the temperature being lowered via circulation is discharged via a vent hole reserved on the bottom of the truck bed, and a draught fan is mounted at the vent hole, for making the air flow in the dual-layer structures flow more smoothly.

Description

technical field [0001] The invention relates to an induced fan device for heating a dump truck box with tail gas. Background technique [0002] In the north of my country, the winter is long and cold. When the dump truck transports materials in severe cold conditions, the materials (especially the materials containing water) are easy to freeze inside the car and cause material blockage. The car will use the engine exhaust to heat the air intake device, and the chassis engine exhaust Connected to the dump truck box, it has the function of heating the truck box, so that the material can be separated from the truck box smoothly to achieve normal work. The traditional exhaust gas heating device only heats the bottom of the box, but cannot heat the side of the box, causing the material and the side of the box to freeze. When the box is lifted, the material cannot be completely unloaded, and there will always be residue around the side of the box, which is wasteful. Manpower and m...

Problems solved by technology

The traditional exhaust gas heating device only heats the bottom of the box, but cannot heat the side of the box, causing the material and the side of the box to freeze. When the box is lifted, the material cannot be completely unloaded, and there will always be residue around the side of the box, which is wasteful. Manpower and material resources affect work efficiency

Northwest wind often blows in winter in the north, the temperature on the upwind side of the carriage is lower, and there are more frozen materials, which makes the center of gravity of the carriage shift, and there is even the danger of overturning, so this kind of dump truck cannot work for a long time in winter
