Description

A grinding dust treatment device

technical field

The utility model relates to a dust processing device, in particular to a grinding dust processing device.

Background technique

Dust refers to solid particles suspended in the air. Production dust will pollute the atmosphere and endanger people's health. For some objects that need to be polished, more dust or harmful smoke will be generated during the grinding process. The dust is usually suspended in the air. If the dust suspended in the air is not treated or the treatment effect is not good, the dust will be serious. Affecting the production and working environment will cause harm to the body of production line workers and even induce various diseases; at the same time, the exchange of dusty air with the outside atmosphere will also pollute the outside atmosphere and the surrounding environment.

In the prior art, most of them use filter cartridges, cloth bag dust collectors, dry dust collection systems, etc. for dust collection treatment.

As a further improvement of the utility model, a muffler is provided on the negative pressure exhaust fan.

As a further improvement of the utility model, the spray tower includes several spray pipes and several spray heads arranged at the lower ends of the spray pipes.

As a further improvement of the present utility model, the airflow uniform distribution plate is in the shape of an inverted V as a whole, and the thickness of the airflow uniform distribution plate is 8-12 mm.

The beneficial effects of the utility model are as follows: the dust is pretreated through the dust filter to remove larger particle dust, and then the fine particles are wet-treated by using the combination of the circulating water treatment pool, the circulating water pump and the spray tower, so as to achieve The dust in the grinding workshop is effectively and comprehensively treated, thereby improving the working environment and reducing the damage to the human body by the dust; through the inverted V-shaped air flow uniform distribution plate, the uniformity of the smoke flow distribution in the casing is improved, thereby improving the stability of the flow field and benefiting the dust. It is evenly distributed in the air in the casing, making the wet treatment of dust faster, more thorough and comprehensive; the anhydrous clean gas after dust removal is recycled to improve energy utilization.

The above is an overview of the technical solution of the utility model, and the utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

detailed description

In order to further explain the technical means and effects of the utility model to achieve the predetermined purpose, the specific implementation of the utility model will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

Embodiment one:

Please refer to Fig. 1, the embodiment of the utility model provides a grinding dust processing device, including a casing 1, a dust suction port 11 is arranged on one side of the casing 1, an exhaust port 12 is arranged on the upper part of the casing 1, the The dust treatment device also includes a dust filter 2 arranged on the outside of the dust suction port 11, a dust collection box 3 arranged on the lower side of the dust filter 2, a negative pressure exhaust fan 4 arranged on the inside of the dust suction port 11, and a dust filter installed on the casing 1. The circulating water treatment tank 5 at the bottom, the circulating water pump 6 arranged in the casing 1 and on the top of the circulating water treatment pond 5, the spray tower 7 arranged in the casing 1 and positioned at the lower side of the exhaust port 12, the spray tower 7 arranged in the spray The dehydration layer 8 between the shower tower 7 and the exhaust port 12 , and the air flow distribution plate 9 arranged between the spray tower 7 and the dehydration layer 8 .

In this embodiment, a plurality of through holes 91 are evenly opened on the air distribution plate 9 , the air distribution plate 9 is in the shape of an inverted V as a whole, and the thickness of the air distribution plate 9 is 8-12 mm.

The spray tower 7 includes several spray pipes 71 and several spray heads 72 arranged at the lower ends of the spray pipes 71 .

The working principle of the grinding dust treatment device in this embodiment is: in the process of grinding objects, a lot of dust will be generated, and under the suction of the negative pressure exhaust fan 4, the dust will follow the air and enter the casing from the dust suction port 11 in the airflow direction A 1. Prior to this, when the dust passes through the dust filter 2, larger particles of dust will be removed and collected in the dust collection box 3; then through the combination of the circulating water treatment pool 5, the circulating water pump 6 and the spray tower 7, Wet removal of small particles of dust entering the casing 1.
