Description

Technical Field

[0001] The utility model relates to the technical field of coating production, in particular to dust removal equipment for coating production. Background Art

[0002] Paint is applied to the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the coated object. It is usually a viscous liquid prepared with organic solvents or water, with resin or emulsion, solvent or water as the main material, and fillers and corresponding additives added.

[0003] In the process of paint production, it is usually necessary to mix and stir a variety of raw materials. Sometimes an open mixing process is adopted. During the mixing process, a large amount of waste gas mixed with dust will be generated. If these waste gases are directly discharged into the air, it will not only pollute the environment, but also when the staff accidentally inhale these waste gases mixed with dust, it will seriously affect the health of the inhaler. Utility Model Content

[0004] The utility model discloses a dust removal device for paint production, which solves the problem that a large amount of waste gas mixed with dust is generated in the traditional paint production process. If the waste gas is directly discharged into the air, it will not only pollute the environment, but also seriously affect the health of the workers who accidentally inhale the waste gas mixed with dust.

[0005] In order to solve the above technical problems, the utility model specifically adopts the following technical solutions:

[0006] A dust removal device for paint production comprises a box body, one side and the top of the box body are respectively connected with an air inlet and an air outlet, a horizontally arranged rotating tube is rotatably connected in the box body, one end of the rotating tube passes through the box body and extends outside the box body, a plurality of spray heads are evenly connected to the rotating tube, a plurality of stirring paddles are evenly fixed on the rotating tube, the spray heads and the stirring paddles are alternately arranged, a motor for driving the rotating tube to rotate around its own axis is provided on the box body, a horizontal filter frame is provided above the rotating tube, a filter screen is fixed in the filter frame, and a water outlet pipe is connected to the bottom of the box body.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] After the external water pipe is connected with the rotating tube, the adsorption liquid is transported to the rotating tube. Since a number of spray heads are evenly connected to the rotating tube, the adsorption liquid can be atomized. After the exhaust gas is introduced into the box from the air inlet, the motor is started to drive the rotating tube to rotate around its own axis, thereby driving the spray head on the rotating tube to rotate. At the same time, the exhaust gas in the box is stirred by a stirring paddle, so that the exhaust gas entering the box can be humidified in all directions, thereby separating the dust mixed in the exhaust gas from the gas. And since a horizontal filter frame is provided above the rotating tube, it can effectively prevent the dust in the exhaust gas from overflowing outside the box during the stirring process, and it can also further filter the separated gas, so that the gas discharged from the outlet is more in line with the environmental emission standards. The utility model has strong practicality. By utilizing a motor to drive the spray head and the stirring paddle on the rotating tube to rotate together, the exhaust gas can be effectively humidified in all directions while stirring the exhaust gas, thereby separating the dust mixed in the exhaust gas from the gas, effectively preventing the exhaust gas mixed with dust from being discharged into the air and causing pollution to the environment, and at the same time avoiding the influence of the exhaust gas mixed with dust on the health of the workers.
