Description

Technical Field

[0001] This utility model relates to the field of alloy steel sheet metal processing, specifically to a sandblasting treatment device for alloy steel sheet metal parts. Background Technology

[0002] Sandblasting uses compressed air to create a high-speed jet that propels abrasive material onto the surface of alloy steel sheet metal parts. This alters the appearance or shape of the parts. Due to the impact and cutting action of the abrasive on the surface, the alloy steel sheet metal parts achieve a certain level of cleanliness and varying roughness, thus improving their mechanical properties. This enhances the fatigue resistance of the alloy steel sheet metal parts, increases the adhesion between the abrasive and the coating, and extends the durability of the coating film.

[0003] Existing sandblasting equipment for alloy steel sheet metal parts generates a large amount of dust during operation. To avoid polluting the working environment and harming the respiratory health of operators, a filter box is usually installed on the equipment. The dust is drawn into the filter box, filtered by the filter screen, and then discharged. However, after long-term use, a large amount of dust easily adheres to the surface of the filter screen, resulting in a decrease in filtration efficiency and affecting the dust removal effect. Therefore, in order to avoid affecting the use of the filter screen, the dust adhering to the filter screen needs to be cleaned every once in a while.

[0004] Currently, some methods for cleaning filters involve removing the filter from the filter unit by disassembling the bolts and other connecting parts that secure it. After removal, workers can clean the dust off the filter. After cleaning, the filter is reinstalled into the filter unit and the connecting parts are tightened. However, this disassembly, cleaning, and installation process is time-consuming and labor-intensive, increasing manual labor intensity. Another cleaning method uses an electric drive mechanism to move a scraper that adheres to the filter surface. The scraper moves downward to remove the dust adhering to the filter surface. However, since the dust generated by sandblasting may contain fine particles or sticky impurities, the scraper can easily leave residue on the edge or surface of the filter mesh. Long-term accumulation can lead to localized blockage of the filter, affecting filtration efficiency. Furthermore, if the force is not properly controlled or the scraper edge is not smooth when it comes into direct contact with the filter surface, it can easily scratch the filter surface and damage the mesh structure, causing the filter to fail and requiring frequent replacement, thus reducing the cleaning efficiency of the filter. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a sandblasting treatment device for alloy steel sheet metal parts to solve the technical problem of inconvenience in cleaning dust adhering to the surface of the filter screen.

[0013] By adopting the above technical solution, the abrasive can enter the sandblasting gun through the feed pipe, and then be sprayed onto the surface of the sheet metal parts through the sandblasting gun, thereby sandblasting the sheet metal parts.

[0014] Furthermore, a fan is installed inside the air outlet, and multiple air extraction pipes connect the air collection box and the sandblasting box.

[0015] By adopting the above technical solution, when dust removal is carried out, the fan can be started, and the fan can extract the dust in the sandblasting box.

[0016] Furthermore, the sandblasting box has material inlets on both sides, and a conveyor belt, which is a conveyor mesh belt, is installed between the two material inlets.

[0017] By adopting the above technical solution, the conveyor belt can transport sheet metal parts to the inside of the sandblasting box.

[0018] Furthermore, a material discharge port is provided at the top of the bottom box, and a guide hopper is installed inside the top of the bottom box.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of this utility model will be described below based on its overall structure.

[0039] Example 1:

[0040] A sandblasting device for alloy steel sheet metal parts, such as Figures 1-7 As shown, the system includes a base box 1, a sandblasting box 2 mounted on top of the base box 1, an air collection box 16 fixed to the back of the sandblasting box 2, a filter box 17 mounted on the back of the air collection box 16, an air outlet 28 mounted on the back of the filter box 17, an inlet 22 on the top of the filter box 17, a mesh frame 18 extending into the filter box 17 inserted inside the inlet 22, a filter screen 19 installed inside the mesh frame 18, and a mounting plate 27 fixed to the top of the mesh frame 18. Both the mesh frame 18 and the filter screen 19 are made of 304 stainless steel. The mounting plate 27 is fixedly connected to the filter box 17 by bolts. The bottom of the mounting plate 27 is provided with a sealing gasket made of nitrile rubber, and the bottom of the sealing gasket fits against the top of the filter box 17 to improve the sealing between the mounting plate 27 and the filter box 17. An electric push rod 23 is mounted on one side of the top of the filter box 17, and a diverter pipe 24 is mounted on the output end of the electric push rod 23 through a piston rod.

[0041] See Figures 2-7 Multiple nozzles 25 are installed on one side of the diversion pipe 24, and a water supply hose 26 extending through to the outside of the filter box 17 is installed on the other side of the diversion pipe 24. The water supply hose 26 is a nitrile rubber hose. One end of the water supply hose 26 is connected to the outlet of an external high-pressure water pump through a flange. Multiple nozzles 25 are equidistantly distributed on the diversion pipe 24. The nozzles 25 are located on one side of the filter screen 19. A discharge pipe 21 is connected to the bottom side of the filter box 17. A discharge valve 30 is installed on the discharge pipe 21. When it is necessary to clean the dust attached to the filter screen 19, the operator can start the external high-pressure water pump. The high-pressure water pump delivers water to the water supply hose 26, and the water then enters the diversion pipe 24 and is sprayed out through the nozzles 25. The filter box 17 is connected to the gas collection box 16 and the gas outlet 28 respectively, so that the gas can enter the filter box 17 through the gas collection box 16, be filtered by the filter box 17, and then be discharged through the gas outlet 28.

[0042] Specifically, the sandblasting box 2 has multiple mounting brackets 9 installed inside. A sandblasting gun 10 is mounted on one side of each mounting bracket 9, and the feed end of the sandblasting gun 10 is connected to a feed pipe 11 extending to the outside of the sandblasting box 2. A feed pipe 31 is installed at the end of the feed pipe 11, and the feed end of the feed pipe 31 is connected to the outlet of an external sandblasting host via a flange. Abrasive can enter the sandblasting gun 10 through the feed pipe 11 and then be sprayed onto the surface of the sheet metal parts, thus performing sandblasting treatment on the sheet metal parts. A fan 29 is installed inside the air outlet 28. Multiple extraction pipes 15 connect the air collection box 16 and the sandblasting box 2. When dust removal is required, the fan 29 can be activated to extract dust from the sandblasting box 2. Both sides of the sandblasting box 2 have feed ports 3. A conveyor belt 5 is installed, which is a conveyor mesh belt. The conveyor belt 5 can transport sheet metal parts to the inside of the sandblasting box 2. A sealing door 13 is installed on the outer surface of the sandblasting box 2 via a hinge. An observation window 14 is installed on the sealing door 13 to facilitate the observation of the internal condition of the sandblasting box 2 by the operator. Soft curtains 4 are installed above the inside of the two material inlets 3. The soft curtains 4 are made of nitrile rubber material and can block the material inlets 3 to prevent abrasive from flying out of the material inlets 3. A control panel 12 is installed above the outer surface of the sandblasting box 2. The control panel 12 is electrically connected to the fan 29, the electric push rod 23 and the conveyor belt 5 respectively, so that the operator can start or stop the fan 29, the electric push rod 23 and the conveyor belt 5 through the control panel 12.

[0043] Example 2:

[0044] Based on the above embodiment one, the following method will be adopted to facilitate the drainage of water.

[0045] See Figures 2-7 The bottom of the filter box 17 is inclined on one side so that the water and dust after washing can flow into the discharge pipe 21 and be discharged through the discharge pipe 21, thus facilitating drainage.

[0046] Example 3:

[0047] Based on the above embodiment 1, in order to improve the sealing between the mesh frame 18 and the filter box 17, the following structure will be set.

[0048] See Figures 4-7 The outer wall of the mesh frame 18 is provided with a sealing strip 20 made of nitrile rubber. The outer wall of the sealing strip 20 fits against the inner wall of the filter box 17. The sealing strip 20 can improve the sealing between the mesh frame 18 and the filter box 17, preventing gas from entering the gas outlet 28 through the gap between the mesh frame 18 and the filter box 17 without being filtered by the filter screen 19.

[0049] Example 4:

[0050] Based on the above embodiment one, the following structure will be set up to facilitate the collection of abrasive.

[0051] Specifically, the bottom box 1 has a discharge port 7 at the top, and a guide hopper 6 is installed inside the bottom box 1 so that the abrasive can fall into the guide hopper 6 through the discharge port 7, and then slide into the collection box 8 through the guide hopper 6. The collection box 8 is placed inside the bottom box 1 and is detachably connected to the bottom box 1. The top size of the collection box 8 is larger than the bottom size of the guide hopper 6. The collection box 8 is located directly below the guide hopper 6 and can collect the abrasive.

[0052] The working principle of this utility model is as follows: First, before use, the operator connects the feed pipe 31 to the outlet of the external sandblasting host, then connects the water supply hose 26 to the external high-pressure water pump, and then turns on the power. Then, the operator places the alloy steel sheet metal parts on the conveyor belt 5. The conveyor belt 5 sends the sheet metal parts into the sandblasting box 2 through the feed port 3. The external sandblasting host transports the abrasive to the sandblasting gun 10 through the feed pipe 31 and the supply pipe 11. The sandblasting gun 10 sprays the abrasive at high speed onto the surface of the sheet metal parts, and completes the surface treatment by utilizing the impact and cutting action of the abrasive. The operator can observe the situation inside the sandblasting box 2 through the observation window 14.

[0053] At the same time, the fan 29 is started. The dust generated during the sandblasting process is drawn into the air collection box 16 by the fan 29 through the air extraction pipe 15, and then enters the filter box 17. After the dust is filtered by the filter screen 19, the gas is discharged through the air outlet 28.

[0054] Furthermore, staff can periodically clean the dust adhering to the surface of the filter screen 19. Before cleaning, staff can place a water collection tank directly below the discharge pipe 21, then start the external high-pressure water pump. Water enters the diversion pipe 24 through the water delivery hose 26, and then rinses the filter screen 19 through the nozzle 25. At the same time, the electric push rod 23 is activated, which can drive the diversion pipe 24 to move, achieving comprehensive cleaning. The discharge valve 30 is opened, and sewage and dust residue flow along the inclined surface of the filter box 17 into the discharge pipe 21, and then are discharged through the discharge pipe 21 and flow into the water collection tank.

[0055] The abrasive material that falls off during the sandblasting process enters the guide hopper 6 through the drop port 7 and is eventually collected in the collection box 8 located directly below the guide hopper 6, thus achieving the collection of abrasive material.

[0056] When the filter screen 19 needs to be removed, the operator can unscrew the bolts on the mounting plate 27, and then pull the mounting plate 27 to move the mounting plate 27 upward and move the mesh frame 18 and filter screen 19 upward. After the mesh frame 18 and filter screen 19 are moved out of the filter box 17, the filter screen 19 can be taken out.

[0057] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
