Working environment, reduce the physical damage of dust to production line workers.

In order to achieve the above object, the utility model adopts the following technical solutions:

A metal grinding dust treatment equipment, including a gas collecting pipe, a dust filter, a spray tower, a filter, and a liquid supply tank; Inside; corresponding to the air intake side of the dust filter, a dust collection port is opened on the bottom wall of the air collecting pipe, and a dust collection cover is provided under the dust collection port, and the middle section of the dust collection cover is arched downwards to collect larger dust. The concave cavity of particle dust, the dust cover can be opened and closed to cover the dust collection port; the spray tower has an air inlet and an air outlet, and the lower part of the spray tower is equipped with a filter support net, the spray tower A spray pipe is installed in the upper part of the inner section, and a number of nozzles for spraying downwards are arranged on the spray pipe. The spray pipe is connected to the aforementioned liquid supply tank through the liquid supply pipe and the first suction pump; the outlet of the spray tower The gas port is located above the spray pipe, and the aforementioned filter is connected to the gas outlet of the spray tower.

As a preferred solution, a spray liquid reuse port is provided at the bottom of the spray tower, and the spray liquid reuse port is installed on a safety filter. For the shower pipe, a second suction pump is connected to the recycling pipe; a switching valve is arranged on the aforementioned liquid supply pipe, and the switching valve is located between the recycling pipe and the first suction pump.

As a preferred solution, swirl plates are installed on the filter support net.

As a preferred solution, a dust collection bucket is arranged directly opposite the dust collection cover, one end of the dust collection cover is rotatably connected with respect to the air collection pipe, and the other end of the dust collection cover can be opened and closed and locked on the air collection pipe.

Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical scheme that it mainly removes larger particle dust through the dust filter, and then uses a spray tower to wet the fine particles. Finally, the water-containing gas is further filtered through the filter, so as to achieve better purification and dust removal treatment for the metal grinding workshop, thereby improving the working environment of the workshop to a large extent and reducing the physical damage of dust to production line workers.

In order to illustrate the structural features and functions of the utility model more clearly, the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
