Description

Technical Field

[0001] The utility model belongs to the technical field of coating machines. Specifically, the utility model relates to a dust exhaust and collection device for a coating machine. Background Art

[0002] A large amount of dust is generated during the coating process of a coating machine. If this dust cannot be effectively collected, it will cause a certain amount of dust pollution to the environment, and it is very difficult to clean up a large amount of dust scattered around.

[0003] In a published specification with a patent number of 202123260970.X and a publication date of July 1, 2022, a high-efficiency dust removal device for a coating machine is disclosed, which includes a coating machine and support legs for supporting the coating machine. An air outlet pipe is provided at the upper end of the coating machine, a cross plate is provided on one side of the coating machine, and a first dust removal device is provided on the cross plate. The first dust removal device includes a filter barrel provided on the cross plate, filter water is provided in the filter barrel, and a detachable second dust removal device is provided at the upper end of the filter barrel. The beneficial effects of the utility model are as follows: The utility model transports the gas discharged from the coating machine to the filter barrel through the air outlet pipe. First, it is filtered by the filter water, and the dust combines with the filter water and precipitates. The filtered gas continues to move upward, passes through the filter holes, enters the dust removal plate for secondary dust removal, and finally is discharged to the outside. Through the double-layer filtration of the first dust removal device and the second dust removal device, the filtration effect is better and more efficient.

[0004] In the above prior art, since the air outlet pipe is directly submerged in the water in the filter barrel, when the dust removal stops, water backflow will occur due to the pressure difference, and due to the high requirement for sealing of the internal structure, the structure is relatively complex. Content of the Utility Model

[0005] The utility model aims to provide a dust exhaust and collection device for a coating machine with a simple structure.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: A dust exhaust and collection device for a coating machine, including a water bucket, in which water is stored.

The dust discharging structure includes a dust exhausting member located above the water surface and a dust exhaust pipe connected to the dust exhausting member.

[0007] A water inlet pipe and a water outlet pipe are provided on the water bucket.

[0008] The dust exhausting member is an outer cylinder connected to the end of the dust exhaust pipe, and an anti-backflow structure is provided in the dust exhausting member.

[0009] One end of the dust exhausting member close to the water surface is an outlet pipe that opens outward in a flared shape.

[0010] One end of the dust exhausting member connected to the dust exhaust pipe is an expansion pipe.

[0011] The expansion tube is thick in the middle and thin at both ends.

[0012] The anti-backflow structure is a funnel arranged in the outlet pipe, and the edge of the funnel fits against the inner wall of the outlet pipe.

[0013] The surface of the water bucket is covered with a filter screen.

[0014] The technical effect of the present utility model is that the dust removal and collection device for a coating machine can effectively collect the dust generated during the coating process of the coating machine by means of water washing, reducing the dust pollution to the environment. Moreover, through the design of multiple funnel shapes, it can not only reduce the rate of dust in the exhaust air, effectively drop the dust into the water, but also play a role in preventing backflow, making the dust removal and collection device for the coating machine simple, convenient and environmentally friendly.

[0017] The marks in the figure are: 1, water bucket; 2, dust discharging structure; 21, dust removing part; 211, outlet pipe; 212, expansion tube; 22, dust discharging pipe; 3, water inlet pipe; 4, water outlet pipe; 5, anti-backflow structure; 6, filter screen. Detailed Description of the Preferred Embodiments

[0018] Next, with reference to the drawings, through the description of the embodiments, the specific embodiments of the present utility model will be further described in detail. The purpose is to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present utility model, and to facilitate its implementation.

[0019] Please refer to Figure 1 , a dust removal and collection device for a coating machine, including a water bucket 1 with water stored therein. A dust discharging structure 2 for preventing backflow is provided in the water bucket 1. The dust discharging structure 2 includes a dust removing part 21 located above the water surface and a dust discharging pipe 22 connected to the dust removing part 21. The dust removal and collection device for the coating machine can effectively collect the dust generated during the coating process of the coating machine by means of water washing, reducing the dust pollution to the environment. Moreover, through the design of multiple funnel shapes, it can not only reduce the rate of dust in the exhaust air, effectively drop the dust into the water, but also play a role in preventing backflow, making the dust removal and collection device for the coating machine simple, convenient and environmentally friendly.

[0020] A water inlet pipe 3 and a water outlet pipe 4 are provided on the water bucket 1; the sewage in the water bucket 1 is drained through the water outlet pipe 4, and the water inlet pipe 3 is put into clean water for collecting dust.

[0021] The dust exhaust member 21 is an outer cylinder connected to the end of the dust exhaust pipe 22. An anti-backflow structure 5 is provided inside the dust exhaust member 21. Dust enters the water bucket 1 through the dust exhaust pipe 22 and the outer cylinder and dissolves in the water. At the same time, the anti-backflow structure 5 can prevent the backflow of water and dust when the blower stops working, thus avoiding pipeline pollution.

[0022] One end of the dust exhaust member 21 close to the water surface is an outlet pipe 211 that flares outwards. By using the flared shape of the outlet pipe 211, dust spillage can be effectively prevented, reducing dust spillage and improving the dust collection efficiency and quality. At the same time, the bottom end of the outlet pipe 211 is slightly close to the water surface, which can effectively suck the dust into the water.

[0023] One end of the dust exhaust member 21 connected to the dust exhaust pipe 22 is an expansion pipe 212. The expansion pipe 212 is used to reduce the efficiency of dust extraction, avoid too high gas flow velocity, which affects the efficiency of dust dissolving in water. And when the flow velocity is too high, it is easy to cause extrusion on the water surface, making the dust quickly pass through between the outlet pipe 211 and the water surface, resulting in the situation of being unable to dissolve.

[0024] The middle of the expansion pipe 212 is thick and both ends are thin. Because the middle section of the expansion pipe 212 is thick, when the gas passes through the middle section of the expansion pipe 212, the flow velocity will be significantly reduced, achieving the effect of reducing the flow velocity.

[0025] The anti-backflow structure 5 is a funnel arranged inside the outlet pipe 211, and the edge of the funnel fits against the inner wall of the outlet pipe 211. The gas will be discharged outwards through the funnel, and the presence of the funnel can reduce the occurrence of backflow.

[0026] The surface of the water bucket 1 is covered with a filter screen 6, which can prevent dust from overflowing from the water bucket 1 and causing pollution to the external environment.

[0027] The technical effect of the present utility model is that the dust exhaust and collection device for the coating machine can effectively collect the dust generated during the coating process of the coating machine by means of water washing, reducing the dust pollution to the environment. And through the design of multiple funnel shapes, it can not only reduce the rate of dust in the exhaust air, effectively drop the dust into the water, but also play a role in preventing backflow, making the dust exhaust and collection device for the coating machine simple, convenient and environmentally friendly.

[0028] The present utility model has been described exemplarily in combination with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present utility model; or without improvement, the above concept and technical solution of the present utility model are directly applied to other occasions, they are all within the protection scope of the present utility model.
