Wet dust collection device with anti-explosion function and polishing system

Abstract

The invention relates to a wet dust collection device with an anti-explosion function. The wet dust collection device comprises an air guiding spraying system and a wet dust collection system communicated with the tail end of the air guiding spraying system, wherein the air guiding spraying system comprises an air suction pipe and a first exhaust fan; the air suction pipe is used for collecting and guiding dust; the first exhaust fan is located on the air suction pipe; an air guide port, through which the dust can one-way enter, is arranged on the air suction pipe; the wet dust collection system comprises a purifying chamber communicated with the end part of the air suction pipe; a wet purifying component and a filtering component are respectively arranged above and under the purifying chamber; the top of the purifying chamber is communicated with the outside through a pipeline; an explosion vent is arranged on a side wall of the purifying chamber. The wet dust collection device provided by the invention is reliable in structure and high in safety; the possibility of dust explosion can be effectively reduced; the access is timely turned off after explosion, so that the harm to worker caused by the secondary explosion on the polishing position is avoided; the dust-containing air is purified for three times before the air is discharged; the dust purifying effect is promoted; the dust can reach the direct emitting environmental protection standard.

Description

technical field [0001] The invention relates to sorting technology, in particular to a wet dust removal device and a grinding system with explosion-proof function. Background technique [0002] Grinding is a commonly used production process. It is a kind of surface modification technology. Usually, according to the surface requirements of the product, the corresponding grinding method, grinding tools and grinding materials are selected. It generally refers to a processing method that uses rough objects (sandpaper with higher hardness particles, etc.) to change the physical properties of the surface of the material through friction. The main purpose is to obtain a specific surface roughness. [0003] Dust is often produced during the grinding process. These dusts are suspended or shrouded on the work station, which not only affects the health of the operation work station. When the dust accumulates to a certain extent, there is a possibility of fire or explosion, which is a v...

Problems solved by technology

[0003] Dust is often produced during the grinding process. These dusts are suspended or shrouded on the work station, which not only affects the health of the operation work station. When the dust accumulates to a certain extent, there is a possibility of fire or explosion, which is a very serious safety hazard. Hidden danger

In order to improve the environment of the grinding station, it is often necessary to install a dust removal device at the station to remove the dust generated by the grinding as soon as possible; at present, the more commonly used grinding and dust removal device is such as the grinding and dust removal device disclosed in Chinese patent ZL201410124186.1, which is based on spraying The simple wet dust removal device composed of the wet curtain unit has a simple structure, but the dust removal effect is not ideal, especially the safety risk caused by the dust explosion cannot be avoided

[0004] Most of the current grinding and dust removal devices adopt the structure disclosed in the above patent number. After the dust is collected by the pipeline, it is directly purified and discharged through the wet dust removal system. On the one hand, simple spraying cannot effectively purify the dust in the air, and its PM2.5 cannot meet the direct On the other hand, in the dust, especially the dust with deflagration characteristics, it is very easy to explode in extreme situations during the collection process. The existing technology is related to preventive measures to avoid explosions, and there is no timely shutdown after dust removal and explosion. access, to avoid detonating the setting of dust in the grinding station, the actual production safety of this type of grinding and dust removal device is difficult to be guaranteed
