Efficient dust absorbing device for unloading work of bulk-grain carrier

Abstract

The invention discloses an efficient dust absorbing device for unloading work of a bulk-grain carrier, and relates to the field of grain logistics. The device comprises an air draft pipe (1), a connecting section (2), a rear air baffle (3), a left air baffle and a right air baffle, and further comprises a top plate (4), an inner air guide plate (5), a transverse air draft pipe (6) and an air draft opening. The inner air guide plate (5) is arranged on the lower portion of the top plate (4), the inner air guide plate, the left air baffle, the right air baffle and the rear air baffle (3) form a vertical air draft channel, and the vertical air draft channel is communicated with the air draft pipe (1) through the connecting section (2). The device can capture dust generated during unloading of the bulk-grain carrier.

Description

technical field [0001] The invention relates to the field of grain logistics, in particular to a dust capture device for bulk grain vehicles unloading grain. Background technique [0002] Bulk grain vehicles will generate a lot of dust when loading and unloading grain. If the dust is not controlled well, it will cause environmental pollution and affect the health of employees. At present, the method for controlling dust spillage in the unloading operation of bulk grain vehicles is to install a suction hood on the grain pit. The existing suction hoods are as follows: figure 1 As shown, it is composed of suction pipe 1, connecting section 2, front windshield 3, left windshield and right windshield, etc. The dust collection device with this structure has the following problems: 1) There is a dead zone in the suction effect, the main reason is that when the bulk grain truck is unloading grain, the space above the grain pit is divided into the main dust area by the downward move...

AI Technical Summary

Problems solved by technology

The dust collection device with this structure has the following problems: 1) There is a dead zone in the suction effect, the main reason is that when the bulk grain truck is unloading grain, the space above the grain pit is divided into the main dust area by the downward movement of grain11 and the auxiliary dust area 12, the air suction has a better ability to catch the dust in the main dust area 11, and due to the barrier effect of the downward moving grain layer on the air suction, the influence of the air suction on the dust in the auxiliary dust area 12 The capacity is small, and the dust overflowing from the auxiliary dust area 12 cannot be effectively captured, resulting in different speeds of grain unloading, and different dust collection effects when the unloading amount is large or small. Even if the air suction volume is increased, the effect on the auxiliary dust area 12 is also Not obvious; 2) In order to meet the functions of bulk grain vehicles entering and exiting and unloading grain, the suction hood is generally designed higher, the air volume required is large, the suction effect of the upper part is stronger, and the suction effect of the lower part is weaker. After the car unloads the grain and leaves, the spilled dust generated when the grain in the pit flows downwards out of the pit is difficult to catch

Therefore, the existing bulk grain vehicle unloading dust suction device has high energy consumption, and the effect of controlling dust overflow during the dynamic process of unloading grain is unstable, and the dust collection effect is not ideal
