Both the dust removal chamber and the control chamber are connected to the water tank. A filter tank is provided in the water tank. A spray pipe, a baffle plate assembly, and a fan are arranged sequentially from bottom to top in the dust removal chamber. A wastewater / dust inlet is provided on the side wall of the dust removal chamber. A wastewater / dust outlet is provided on the main body of the workstation. The wastewater / dust outlet is connected to the wastewater / dust inlet. A water pump is provided in the control chamber. The water pump inlet is connected to one end of an inlet pipe. The other end of the inlet pipe is located in the water tank. The water pump outlet is connected to one end of an outlet pipe. The other end of the outlet pipe is connected to a spray pipe. The spray pipe is connected to the outlet pipe.

[0005] Furthermore, the spray pipe is provided with spray holes.

[0006] Furthermore, the wastewater / dust inlet is located between the filter tank and the shower pipe.

[0007] Furthermore, the side wall of the water tank is provided with a drain outlet and a water inlet, and a liquid level sensor is installed inside the water tank.

[0008] Furthermore, a hydrogen sensor is installed on the dust removal hood.

[0009] Furthermore, a valve is installed on the water outlet pipe, and a flow meter and a pressure gauge are installed on the shower connection pipe.

[0010] Furthermore, the baffle assembly includes an outer frame and multiple baffles, with the multiple baffles arranged side by side inside the outer frame. The bottom and top of the outer frame are respectively provided with an air inlet and an air outlet.

[0011] Furthermore, all of the baffles have an S-shaped structure.

[0013] Furthermore, another technical objective of the present invention is to provide a method for operating a grinding and polishing workstation.

[0014] The above-mentioned technical objective of the present invention is achieved through the following technical solution.

[0015] A working method for a grinding and polishing workstation involves treating the dust generated during the grinding of a workpiece using a water curtain dust removal device. The method is characterized by: using a fan to draw air containing fine dust particles into the dust removal chamber through a wastewater / dust inlet, while simultaneously, wastewater flows into a filter tank through the same inlet; as the air containing fine dust particles rises, water mist is sprayed through the spray pipes, causing some of the fine dust particles to come into contact with the water mist and, through their own inertia, fall into the filter tank, thus achieving dust removal and purification; another portion of the fine dust particles continues to rise in the air and undergoes secondary filtration through a set of baffle plates; a water pump supplies water from the tank to the spray pipes via inlet and outlet pipes, thereby achieving internal water circulation between the workstation and the water curtain dust removal device.

[0016] Compared with the prior art, the present invention has the following advantages: the water curtain dust removal equipment is applicable to different models of grinding and polishing workstations. The grinding and polishing workstation only needs to install a spray pipe at the top and open a sewage / dust outlet at the bottom to connect with the water curtain dust removal equipment. The fan in the water curtain dust removal equipment can draw dust into the dust removal chamber with the wind, and the debris can flow into the filter tank with the water. The filter tank can filter the debris, the spray pipe can perform preliminary treatment of dust, the baffle plate group can perform secondary treatment of dust, and the water pump can supply water in the water tank to the spray pipe and spray pipe, thereby realizing the dust removal function and the water circulation function.

[0032] The water curtain dust removal device in this embodiment includes a dust removal hood 1. The lower part of the dust removal hood 1 is a water tank 11. The upper part of the dust removal hood 1 is divided into a dust removal chamber 12 and a control chamber 13. Both the dust removal chamber 12 and the control chamber 13 are connected to the water tank 11. A filter tank 2 is provided in the water tank 11. A shower pipe 3, a baffle plate group 4 and a fan 5 are arranged in the dust removal chamber 12 from bottom to top. A sewage / dust inlet 14 is provided on the side wall of the dust removal chamber 12. The sewage / dust inlet 14 is located between the filter tank 2 and the shower pipe 3.

[0033] In this embodiment, a water pump 6 is installed in the control compartment 13. The water inlet of the water pump 6 is connected to one end of the water inlet pipe 61, and the other end of the water inlet pipe 61 is located in the water tank 11. The water outlet of the water pump 6 is connected to one end of the water outlet pipe 62. The shower pipe 3 and the water outlet pipe 62 are connected through the shower connecting pipe 63.

[0034] In this embodiment, the side wall of the water tank 11 is provided with a drain outlet 15 and a water inlet 16. A liquid level sensor 17 is installed inside the water tank 11. A hydrogen sensor 18 is installed on the dust removal hood 1. A valve 64 is installed on the water outlet pipe 62. A flow meter 65 and a pressure gauge 66 are installed on the shower connection pipe 63.

[0035] In this embodiment, the baffle assembly 4 includes an outer frame 41 and multiple baffles 42. The multiple baffles 42 are all S-shaped and arranged side by side inside the outer frame 41. The bottom and top of the outer frame 41 are respectively provided with an air inlet 44 and an air outlet 45. Each baffle 42 is provided with a baffle plate 43 at an angle.

[0036] The polishing workstation in this embodiment includes a workstation body 8, a spray pipe 7, and a water curtain dust removal device. The spray pipe 7 is installed inside the workstation body 8 and located at the top of the workstation body 8. Both the workstation body 8 and the spray pipe 7 are connected to the water curtain dust removal device. Spray holes 71 are provided on the spray pipe 7.

[0037] In this embodiment, the other end of the spray pipe 7 and the water outlet pipe 62 are connected by a spray connecting pipe 72. The main body 8 of the workstation is provided with a sewage / dust outlet 81, which is connected to the sewage / dust inlet 14.

[0038] The working method of the grinding and polishing workstation in this embodiment is as follows: the dust generated when the workpiece is ground by the main body 8 of the workstation is treated by the water curtain dust removal equipment. The air containing fine dust particles is drawn into the dust removal chamber 12 through the sewage / dust inlet 14 by the negative pressure adsorption of the fan 5. At the same time, the sewage flows into the filter tank 2 through the sewage / dust inlet 14. As air containing fine dust particles rises, water mist is sprayed out through the shower pipe 3, causing some of the fine dust particles to come into contact with the water mist. During the collision process, the fine dust particles fall into the filter tank 2 due to their own inertia, thereby achieving the effect of dust removal and purification. Another portion of fine dust particles continues to rise in the air, and can be filtered a second time by the set baffle group 4; Water pump 6 can supply water from water tank 11 to shower pipe 3 and spray pipe 7 via water inlet pipe 61 and water outlet pipe 62, thereby realizing internal water circulation between the main body of workstation 8 and water curtain dust removal equipment.

[0039] Specifically, the water curtain dust removal equipment can be used to treat the dust and debris generated during the grinding and polishing process of the workpiece in the main body 8 of the workstation. Fine dust particles are drawn into the dust removal chamber 12 by the fan 5 and pass through the spray pipe 3 and the baffle plate group 4 for preliminary treatment and secondary treatment respectively. During the preliminary treatment, the spray pipe 3 sprays water mist to contact some of the fine dust particles that rise with the air, causing some of the fine dust particles to fall into the filter tank 2. During the secondary treatment, another part of the fine dust particles that rise with the air comes into contact with the baffle plate 42 and hangs on the baffle plate 42. At the same time, debris and fine dust particles from the preliminary treatment flow into the filter tank 2 for filtration. Water in the water tank 11 is transported to the spray pipe 7 and the spray pipe 3 through the water inlet pipe 61, the water pump 6, and the water outlet pipe 62.

[0040] The water curtain dust removal equipment is applicable to various workstation bodies 8. The wastewater / dust outlet 81 on the workstation body 8 is connected to the wastewater / dust inlet 14 on the water curtain dust removal equipment. The wastewater and dust generated when the workstation body 8 grinds and polishes the workpiece enter the water curtain dust removal equipment through the wastewater / dust outlet 81 and the wastewater / dust inlet 14.

[0041] The filter tank 2 can filter the debris generated during the polishing process and the fine dust particles sprayed by the shower pipe 3. The shower pipe 3 is used to spray water mist to contact the fine dust particles in the air for preliminary treatment. The baffle 42 in the baffle assembly 4 is a water curtain paper. Its function is to block the fine dust particles in the air when the air flows through the baffle assembly 4. The baffle 42 is set as an S-shaped structure and the blocking plate 43 is set on the baffle 42 at an angle to increase the contact area with the air so that the fine dust particles can contact the baffle 42 and the blocking plate 43. When the liquid level sensor 17 detects that the water level in the water tank 11 is too low, water can be added to the water tank 11 through the water inlet 16. When the water in the water tank 11 needs to be replaced, the water can be discharged through the drain outlet 15. The hydrogen sensor 18 is used to detect the hydrogen concentration in the dust removal hood 1.

[0042] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components, etc. The above description is merely illustrative of the structure of the present invention. All equivalent or simple variations made based on the structure, features, and principles described in this invention are included within the scope of protection of this invention. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to substitute them, as long as they do not depart from the structure of the invention or exceed the scope defined by the claims, all of which should fall within the scope of protection of this invention.
