Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of grain processing, in particular to a grain processing dust collecting device. BACKGROUND

[0002] In the process of grain processing, such as grain milling, rice milling, screening and other links, a large amount of dust will be produced. These dust not only pollutes the processing environment and affects the health of the operators, but also may cause fire hazards and other safety hazards. Therefore, the grain processing industry generally uses dust collecting devices to reduce the spread and accumulation of dust.

[0003] Traditional dust collecting devices usually include a dust collector connected to the dust source of the grain processing point through a dust suction port, which sucks in the generated dust and processes it. The treated tail gas is discharged into the atmosphere through a tail gas exhaust pipe, and the collected dust is discharged through a dust discharge port. However, these traditional dust collecting devices still have some deficiencies in actual application.

[0004] Technical defects of prior art

[0005] Low dust collection efficiency: traditional dust collecting devices can only collect part of the dust, especially for fine dust suspended in the air, the collection effect is limited.

[0006] Incomplete tail gas treatment: the tail gas exhaust pipe directly discharges the treated tail gas, but the tail gas may still contain dust particles that have not been completely treated, causing secondary pollution to the environment. INVENTION CONTENTS

[0007] The utility model provides a kind of grain processing dust collecting device to solve the above-mentioned low dust collection efficiency problem in the prior art.

[0008] The technical scheme for solving the above technical problems is as follows: a kind of grain processing dust collecting device, including multiple groups of dust collectors arranged at grain processing points, tail gas exhaust pipes matched with each dust collector, and dust collecting tanks arranged adjacent to each dust collector;The dust suction port of the dust collector is connected to each grain processing point dust collection point through a pipeline;The tail gas exhaust pipe air inlet is communicated with the tail gas exhaust port of the dust collector;The dust discharge port of the dust collector is communicated with the dust discharge hopper;Multiple dust collection openings are reserved on the dust collecting tank, and a dust collection bag is arranged between the dust discharge hopper and the corresponding dust collection opening.

[0009] On the basis of the above technical scheme, the utility model can also be improved as follows.

[0010] Further, a water supply pipeline is arranged along one side of the dust collecting tank, and a plurality of atomizing nozzles are arranged in the inner cavity of the dust collecting tank and communicated with the water supply pipeline.

[0011] Further, the dust collecting groove bottom is provided with a lower water flow channel along the groove conveying direction.

[0012] Further, the dust discharging hopper is provided with rotatable stirring blades along the discharging direction, and a motor driving element for driving the stirring blades.

[0013] Further, the dust collector is a cyclone dust collector or an electromagnetic pulse dust collector.

[0014] Further, the tail gas exhaust pipe is further provided with an exhaust fan.

[0015] Moreover, the grain processing dust collecting device provided by the utility model has at least the following beneficial effects compared with the prior art:

[0016] The grain processing dust collecting device provided by the utility model is designed to collect dust at the grain processing points through multiple dust collectors, and after preliminary separation, the dust falls into the dust discharging hopper and is then collected and transported to the dust collecting groove through the dust collecting cloth bag. This design not only improves the dust collecting efficiency, but also realizes centralized treatment of the dust, reduces the environmental pollution caused by the dust, and further improves the dust collecting and processing effect.

[0017] The dust discharging hopper in the device is provided with rotatable stirring blades, which are driven to rotate by the motor driving element, effectively preventing the dust from accumulating and caking in the dust discharging hopper and ensuring smooth falling and collecting of the dust. Meanwhile, the dust collector adopts a cyclone dust collector or an electromagnetic pulse dust collector, both of which have high dust removal efficiency and can well meet the dust collecting demand in the grain processing process.
