Description

Technical Field

[0001] The utility model belongs to the technical field of grain production, and more specifically, particularly relates to a dust exhaust device for a pulse dust collector. Background Art

[0002] A large amount of dust will be generated during the primary processing of grains. Therefore, a pulse dust collector is installed in the production process. The pulse dust collector will suck the dust generated during the grain processing into the interior. The dust entering the pulse dust collector reaches the dust exhaust device inside the pulse dust collector. The dust exhaust device then discharges the dust from the dust outlet to the outside of the equipment, thereby ensuring the normal use of the pulse dust collector.

[0003] According to CN201220176438.1, the utility model provides a dust discharge device for a pulse dust collector for grain processing, wherein the dust discharge device is provided with a dust discharge connection port that can be connected to a dust discharge port on one side of the tail of a closed cylindrical barrel, a discharge port is provided on the other side of the front, a shaft with spiral fins is installed in the barrel, and a gravity door is also installed in the front of the barrel. When the utility model is used after being connected to the pulse dust collector, the grain processing dust sucked into the dust collector is processed by the low-pressure pulse purge pipe and the dust falling into the bottom of the dust collector can be discharged from the discharge port through the rotation and twisting of the shaft with spiral fins. Since the device adopts a spiral structure for twisting and discharging, and the connection of the inclined structure and the self-closure of the gravity door when shutting down can ensure that there will be no air leakage while discharging, and solves the problem of easy jamming of the air lock connected to the original equipment and easy burning of the motor. It is a scientific and reasonable dust discharge device that improves work efficiency and reduces maintenance costs.

[0004] Based on the above, the existing dust exhaust device generally drives the dust from the dust outlet through the auger structure. A protective cover is set on the outside of the auger. There is easily a gap between the auger and the protective cover. Due to the small volume of dust, the dust enters the protective cover and adheres to the bottom of the protective cover. The auger is difficult to drive the dust at the bottom to move, so that the dust at the bottom accumulates and affects the discharge of dust. Utility Model Content
