Efficient grain unloading operation dust collection device

Abstract

An efficient grain unloading operation dust collection device comprises a grain unloading platform, a conveyor belt, an air draft system, a dust collection box, a wall body, a foundation pit and a dust collection device, and is characterized in that the wall body is of a vertical structure, the air draft system is fixedly connected to the bottom of one side of the wall body, the grain unloading platform is arranged below the bottom of the wall body, the conveyor belt is fixedly connected to the top of the grain unloading platform, the foundation pit is formed between the conveyor belt and theother side of the wall body, the dust collection device is fixedly mounted in the foundation pit, the dust collection box is fixedly connected to one side, close to the outer side, of the wall body, and the dust collection device comprises a first motor, a connecting shaft, a crankshaft, a first box body, a shaft sleeve, a support, a rotating wheel, a first air outlet, an air inlet, a filter screen, an air blower, an installation plate, a discharging port, a blocking wheel, a stirring wheel, a first rotating shaft, a motor case, a second motor, a limiting frame, a connecting block and a feeding hopper. Grains are scattered through the stirring wheel, the air blower blows out the dust in the grains, and the dust is sucked into the dust collection box through the rotating wheel.

Description

technical field [0001] The invention relates to the technical field of dust collection devices, in particular to a high-efficiency dust collection device for unloading grain. Background technique [0002] With the continuous development of the industrial level, people's living standards continue to improve, and people's attention to the body is also increasing. In the conventional grain unloading operation, a large amount of dust entrained in the grain will be raised, which is harmful to the environment and the body of the workers. There is a certain degree of damage, so the existing grain processing and feed processing enterprises basically use the upper suction dust removal device at the grain pit. This device sucks the dust into the dust collector through the suction port above the operator's body for dust removal. [0003] The invention patent with the patent number of CN103302073A discloses a suction and dust removal device for a grain pit, which includes a dust collect...

Problems solved by technology

[0003] The invention patent with the patent number of CN103302073A discloses a suction and dust removal device for a grain pit, which includes a dust collector, a feeding port and a conveying device. There is an air suction port on the side wall, and the air suction port is connected with the dust collector through the air pipe; the conveying device is arranged under the grain pit, and the present invention can ensure that less dust can fly upwards and be absorbed by the human body, while ensuring the lower The material is unobstructed and has a good suction and dust removal effect, and the working area of ​​the feeding port is large, which improves the work efficiency and reduces the work intensity. However, this device only achieves the effect of dust collection through the connection of the ventilation device and the dust collection device, but it does not make the grain The existing dust is removed, and the dust removal effect is not complete
