Description

Technical Field

[0001] This utility model relates to the field of polishing equipment, and in particular to a spray filtration device for polishing. Background Technology

[0002] Polishing spray filtration devices are used in the polishing process to purify the waste gas containing particulate matter generated after polishing. They are important equipment for improving processing quality and efficiency and are widely used in polishing processes of materials such as metals, glass, and semiconductors to remove dust and pollutants from the waste gas and ensure that the emitted gas meets environmental protection standards.

[0003] In the current equipment's post-spray filtration stage, the method of fixing the filter plates is seriously inadequate. Most filter plates rely solely on simple placement or a preliminary fixing structure. During equipment operation, especially when processing large volumes of waste gas or waste gas containing large particulate pollutants, the filter plates are prone to displacement. This displacement can lead to gaps at the connection between the filter plate and the equipment, allowing unfiltered waste gas to bypass the filter plate and directly enter the subsequent transport pump. This not only reduces filtration efficiency and causes pollutant levels in the exhaust gas to exceed standards, polluting the environment, but may also damage the transport pump.

[0004] Therefore, it is necessary to provide a polishing spray filtration device to solve the above-mentioned technical problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1 to 4 A polishing spray filtration device includes: an upper spray chamber 1, two lower spray chambers 2, a transport pump 3, an exhaust air box 4, and a filtration mechanism 5. The two lower spray chambers 2 are both located at the bottom of the upper spray chamber 1 and are arranged symmetrically. The transport pump 3 is located at the top of the lower spray chambers 2, the exhaust air box 4 is located at the top of the upper spray chamber 1, the filtration mechanism 5 is located inside the lower spray chambers 2, and the polishing mechanism is located inside the lower spray chambers 2. After the polishing mechanism polishes the material, the generated exhaust gas undergoes a first spray filtration in the lower spray chambers 2, and after the filtration mechanism 5 filters out large particulate waste, it is transported by the transport pump 3 to the upper spray chamber 1 for a second spray filtration. Finally, the exhaust air box 4 discharges the waste gas from the two spray filtrations to the outside of the device.

[0022] A guide slope 11 is fixedly connected to the inner wall of the bottom of the upper spray chamber 1, and a guide pipe 12 leading to the outside of the upper spray chamber 1 is provided on the guide slope 11. A spray frame 13 is provided inside the upper spray chamber 1. The spray frame 13 is located above the guide slope 11. A water inlet pipe 131 is provided on the spray frame 13, and several spray heads 132 are provided at the bottom of the spray frame 13. Spray water is introduced into the spray frame 13 from the water inlet pipe 131 and sprayed out through the spray heads 132 to spray the exhaust gas containing powder. The wastewater after spraying is guided by the guide slope 11 to the guide pipe 12 and then to the outside of the device.

[0023] A polishing mounting plate 21 is fixedly connected to the lower part of the lower spray chamber 2. A water collection tank 22 is set between the two lower spray chambers 2, and the water collection tank 22 is located below the polishing mounting plate 21. The bottom end of the guide pipe 12 is located in the water collection tank 22. A second spray frame 23 is set inside the lower spray chamber 2. The second spray frame 23 is located above the polishing mounting plate 21. The second spray frame 23 is also equipped with a water inlet pipe 131 and a spray head 132. A filter plate insertion interface 24 is opened on the upper front side of the lower spray chamber 2. A polishing mechanism is installed on the polishing mounting plate 21. After the material is polished, the first spray frame 13 sprays the exhaust gas containing powder for the first time. A filter mechanism 5 is set in the filter plate insertion interface 24 to filter the exhaust gas that may still contain large particulate impurities. The wastewater after spraying is discharged into the water collection tank 22.

[0024] The transport pump 3 is located on the top of the two lower spray chambers 2, and the input end of the transport pump 3 is located on the inner wall of the top of the lower spray chamber 2. The output end of the transport pump 3 is provided with a transport air duct 31, which is connected to the interior of the upper spray chamber 1. The transport pump 3 transports the exhaust gas after the first spray through the transport air duct 31 to the upper spray chamber 1 for the second spray.

[0025] The air inlet of the exhaust air box 4 is located inside the upper spray chamber 1, and the air outlet is located at the top of the exhaust air box 4. The exhaust air box 4 discharges the exhaust gas that has been sprayed twice to the outside of the device.

[0026] The filtration mechanism 5 includes a displacement component 51, a filter frame 52, and a pressure frame 53. The filtration mechanism 5 is located inside the lower spray chamber 2 and above the second spray frame 23. The displacement component 51 is located above the filter frame 52. The filter frame 52 is inserted into the filter plate insertion interface 24. The pressure frame 53 is located below the filter frame 52 and is fixedly connected to the interior of the lower spray chamber 2. The displacement component 51 can press the filter frame 52 tightly onto the pressure frame 53 to form a sealed state, preventing the exhaust gas that has not been filtered by the filter frame 52 from being transported into the upper spray chamber 1.

[0027] The displacement assembly 51 includes a pressure frame 511 and a linkage table 512. The linkage table 512 is disposed on the side of the lower spray chamber 2. The pressure frame 511 is slidably connected to the interior of the lower spray chamber 2. A guide block 5111 is fixedly connected to the side of the pressure frame 511. A drive plate 5112 is fixedly connected to the side of the pressure frame 511 near the linkage table 512, and the drive plate 5112 is located inside the linkage table 512. A gear 5121 is rotatably connected inside the linkage table 512. A lead screw 5122 is fixedly connected to the top of the gear 5121. The surface of the lead screw 5122 is threadedly connected to the drive plate 5112. When the gear 5121 rotates, the lead screw 5122 rotates. Through the threaded connection with the drive plate 5112 and the guidance of the guide block 5111, the pressure frame 511 slides up and down inside the lower spray chamber 2.

[0028] The filter frame 52 has a sponge board 521 inside, and rubber pads 522 are provided at the top and bottom of the filter frame 52. A rack 523 is provided on the side of the filter frame 52 near the linkage table 512, and the rack 523 meshes with a gear 5121. A limit plate 524 is fixedly connected to the front side of the filter frame 52. Symmetrical fixing holes 525 are opened at both ends of the front side of the limit plate 524. A handle 526 is also fixedly connected to the middle of the front side of the limit plate 524. The limit plate 524 can be adjusted by connecting the connector and the fixing hole 525. Position plate 524 is fixed on filter plate insertion interface 24. When filter frame 52 is placed into lower spray chamber 2 through handle 526, straight rack 523 on the side will mesh with gear 5121 and rotate. Screw 5122 will rotate accordingly, thereby driving pressure frame 511 to move down. Filter frame 52 is pressed tightly on pressure frame 53. Due to the effect of rubber pad 522, the tightness of the top and bottom contact surfaces of filter frame 52 is ensured, ensuring that the exhaust gas transported by transport pump 3 is exhaust gas filtered by sponge plate 521.

[0029] The working principle of the polishing spray filtration device provided by this utility model is as follows:

[0030] The polishing mechanism is installed on the polishing mounting plate 21 inside the lower spray chamber 2. When polishing the material, exhaust gas containing powdery waste is generated. The second spray frame 23 is located above the polishing mounting plate 21. Water is introduced through the water inlet pipe 131 and sprayed out through the spray head 132 to perform initial spraying and sedimentation of particles in the exhaust gas. The wastewater after spraying falls into the collection tank 22, while the exhaust gas containing smaller particles continues to flow upward.

[0031] The filter frame 52 is inserted into the lower spray chamber 2 through the filter plate insertion interface 24. At this time, the filter frame 52 is located between the pressure frame 511 and the pressure receiving frame 53. When the filter frame 52 is pushed, the straight rack 523 on its side meshes with the gear 5121 in the linkage table 512, driving the gear 5121 to rotate. The lead screw 5122 at the top of the gear 5121 rotates accordingly, causing the drive plate 5112 to move through the threaded connection, thereby causing the pressure frame 511 to slide downward (the guide block 5111 ensures that the sliding direction is stable). Finally, the pressure frame 511 presses the filter frame 52 tightly onto the pressure receiving frame 53. The rubber pads 522 at the top and bottom of the filter frame 52 form a seal to prevent the exhaust gas from flowing around. The exhaust gas passes through the sponge plate 521 in the filter frame 52, where large particulate impurities are intercepted. The purified exhaust gas enters the next process.

[0032] The purified exhaust gas is drawn in from the top of the lower spray chamber 2 by the transport pump 3 and transported to the upper spray chamber 1 through the transport air duct 31. The spray frame 13 introduces water through the water inlet pipe 131 and sprays water from the spray head 132 to perform secondary cleaning of the exhaust gas and further remove fine particles. The wastewater after spraying is collected by the guide slope 11 into the guide pipe 12 and discharged into the collection tank 22. The exhaust gas, after two spraying and filtration processes, is extracted from the top by the exhaust air box 4 and discharged into the external environment in compliance with standards.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
