Positive-pressure dust removal equipment for grain production

Abstract

The invention discloses positive-pressure dust removal equipment for grain production. The equipment comprises a supporting leg, cyclone dust collectors, a fan, a spiral feeder and an equipment main body; a material conveying pipe is fixedly mounted on the outer surface of the upper end of the supporting leg, two cyclone dust collectors are arranged, the outer surfaces of the two cyclone dust collectors are each provided with a material inlet, a material falling opening and an impurity outlet, the cyclone dust collectors are fixedly mounted directly above the material conveying pipe, the material falling openings are connected and communicate with the material conveying pipe, and the spiral feeder is fixedly mounted in the material conveying pipe; and the position, close to the upper end,of the outer surface of one side of the equipment main body is fixedly connected with the material conveying pipe. Double dust removal can be carried out on grains, rotatable double impellers can buffer the falling process of the grains, so that the problem that health of workers is affected because dust mixed in the grains is raised and workers inhale the dust is avoided; and the equipment can berapidly disassembled, cleaned and subsequently assembled, and subsequent use of the equipment is facilitated.

Description

technical field [0001] The invention relates to the field of positive pressure dust removal, in particular to positive pressure dust removal equipment for grain production. Background technique [0002] As we all know, a large amount of dust will be produced during the storage, transportation and processing of grain, which not only pollutes the environment and damages the health of workers, but more seriously, under appropriate conditions, grain dust explosion may occur, causing huge personal casualties and economic losses At present, the dust removal technology commonly used in domestic and foreign grain systems is mechanical ventilation dust removal. Due to the influence of factors such as design, installation, use environment and operation management, it is difficult to achieve satisfactory dust removal effect in actual use. From the use situation in our country Look, the dust removal efficiency is very low, some working flour dust is flying, and some working rooms are fu...

Problems solved by technology

[0002] As we all know, a large amount of dust will be produced during the storage, transportation and processing of grain, which not only pollutes the environment and damages the health of workers, but more seriously, under appropriate conditions, grain dust explosion may occur, causing huge personal casualties and economic losses At present, the dust removal technology commonly used in domestic and foreign grain systems is mechanical ventilation dust removal. Due to the influence of factors such as design, installation, use environment and operation management, it is difficult to achieve satisfactory dust removal effect in actual use. From the use situation in our country Look, the dust removal efficiency is very low, some working flour dust is flying, and some working rooms are full of dust, reaching or exceeding the lower limit of the dust explosion dangerous concentration, lurking the risk of dust explosion;

[0003] At the same time, the existing dust removal equipment has low dust removal efficiency, and it is easy to raise dust during blanking, which affects the health of the staff, and it is inconvenient for quick assembly and disassembly, as well as subsequent cleaning, which greatly affects the subsequent use of the equipment. In order to solve the above technical problems , now provides a kind of positive pressure dust removal equipment for grain production
