Flour processing dust explosion prevention assembly capable of automatically backwashing according to wind pressure

Abstract

The invention relates to the technical field of flour processing, and discloses a flour processing dust explosion prevention assembly capable of automatically backwashing according to wind pressure, the flour processing dust explosion prevention assembly comprises a ventilation pipeline, one end of the ventilation pipeline is fixedly connected with a filter screen, the two ends of the filter screen are fixedly connected with a supporting seat, one side of the supporting seat is fixedly connected with a wind pressure detection seat, a first reset spring is fixedly connected to the outer side wall of the wind pressure detection seat, and a trigger rod is hinged to the interior of the wind pressure detection seat. At the moment, the filter screen extrudes a trigger ball on a sliding rod inwards, the trigger ball moves inwards, the trigger ball makes contact with a trigger rod, the trigger rod expands outwards, the trigger rod makes contact with a forward switch key, the device can automatically monitor the wind pressure value of the filter screen, and then the situation of flour particles accumulated on the filter screen is indirectly known; the trouble of manual detection or other complex sensors for detection is avoided, and the labor cost and the economic cost are effectively saved.

Description

technical field [0001] The invention relates to the technical field of flour processing, in particular to a dust explosion prevention component for flour processing that is automatically backwashed according to wind pressure. Background technique [0002] Dust explosion refers to the dust cloud formed by the mixture of combustible dust and air in a confined space. Under the action of the ignition source, the formed dust-air mixture burns rapidly and causes a chemical reaction in which the temperature and pressure rise sharply. Currently, in the flour processing During the process, in order to avoid dust explosion, filter components are usually set up to filter the dust in the air to reduce the dust in the air environment to an appropriate concentration. [0003] In the prior art, during the filtering process of the filter assembly, the flour particles will adhere to one side of the filter screen, causing the flour to accumulate on the filter screen and block the mesh holes o...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a dust explosion-proof component for flour processing that is automatically backwashed according to wind pressure. The advantages of automatic cleaning, saving labor costs and economic costs, solve the problem that during the filtering process of the filter assembly, flour particles will adhere to one side of the filter screen, causing flour to accumulate on the filter screen and block the mesh of the filter screen. Existing devices require manual or complex sensor devices for monitoring and cleaning, which is time-consuming, laborious, and costly
