Description

Technical Field

[0001] This utility model relates to the field of dust removal, specifically to a wet dust removal system for grinding and polishing. Background Technology

[0002] In modern industrial production, grinding and polishing operations are widely used in many fields such as metal processing, machinery manufacturing, furniture production, and building material processing. These operations generate a large amount of dust particles, which not only seriously pollute the working environment and endanger the health of operators, but also pose potential safety hazards such as explosions. To effectively control dust pollution, wet dust collection technology has emerged and is gradually becoming an important means of dust control in grinding and polishing operations.

[0003] Wet scrubbing systems are widely used in grinding and polishing operations. Their basic structure typically consists of an air intake system, a dust collection chamber, a spray system, a drainage system, and an exhaust system. During operation, dust-laden gas enters the dust collection chamber and mixes thoroughly with the liquid droplets or films sprayed from the spray system. Dust particles are wetted and adsorbed by the liquid, settling to the bottom of the chamber and discharged through the drainage system. The purified gas is then exhausted through the exhaust system, thus achieving the purpose of dust removal.

[0004] However, existing wet scrubbing equipment still has some obvious shortcomings when applied to metal grinding and polishing operations. Due to the characteristics of small particle size, high concentration, and high viscosity of the dust generated during grinding and polishing, existing wet scrubbing equipment is prone to insufficient mixing of dust and liquid when dealing with this type of dust. As a result, some dust is not effectively captured, thus reducing the dust removal efficiency. In addition, existing equipment generally only uses a wet scrubbing chamber combined with a spray system for dust removal. However, when dust enters the dust collection chamber through the dust collection suction pipe, it tends to stick to the inner wall of the pipe, which affects the suction effect of the pipe and the subsequent dust removal effect, resulting in poor dust removal efficiency in the exhaust gas. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned deficiencies and provide a wet dust removal system for grinding and polishing, thereby solving the technical problems of poor dust removal efficiency and the tendency of dust to adhere to the inner wall of the dust removal and suction pipe when passing through the dust removal and suction pipe, which affects the subsequent suction and dust removal effect.

[0006] The objective of this utility model is achieved through the following means:

[0007] A wet dust collection system for grinding and polishing includes an explosion-proof fan, a wet scrubber, and a duct spraying device. The explosion-proof fan has an air inlet and an air outlet. The wet scrubber is connected to the air inlet via a connecting pipe. The wet scrubber also has a suction pipe for connecting to grinding and polishing equipment. The end of the suction pipe away from the wet scrubber has a suction port, and the other end of the suction pipe is connected to the wet scrubber. A dust collection chamber is formed inside the wet scrubber, and a spraying assembly is installed inside the dust collection chamber. The spraying assembly includes a first water pump and several spray valves. A collection chamber for collecting spray liquid is formed at the bottom. The spray valve is installed in the dust removal chamber through a mounting bracket. The first water pump is connected to the spray valve and the collection chamber through a pipe, so that the first water pump can supply spray liquid to the spray valve. The pipeline spray device includes a water tank, a second water pump and a spray head. The second water pump is connected to the spray head through a spray pipe and is connected to the water tank through a water inlet. The spray head passes through the dust collection pipe and is built into the dust collection pipe, so that the spray head can cooperate with the suction of the dust collection pipe to spray dust removal. A drain pipe connected to the water tank is provided at the end of the dust collection pipe near the wet dust collector.

[0008] Furthermore, as described above, the spray valve is provided in two sets, and the two sets of spray valves are arranged vertically at intervals.

[0009] By setting two sets of spray valves spaced apart vertically, dust entering the wet scrubber can be sprayed from different heights, increasing the spray coverage area, allowing the dust and liquid to mix thoroughly, improving dust collection efficiency, and thus enhancing the overall dust removal efficiency of the dust removal system.

[0010] Furthermore, as described above, the wet dust collector is equipped with an air inlet and an exhaust outlet that communicate with the dust collection chamber, and a drain valve is provided at the bottom of the wet dust collector.

[0011] The design of the air inlet and exhaust outlet facilitates the entry of dusty gas and the discharge of purified gas. The drain valve at the bottom allows for the easy discharge of dust-containing wastewater collected in the dust removal chamber, ensuring the cleanliness of the chamber, maintaining the normal operation of the dust removal system, and improving the dust removal efficiency.

[0012] Furthermore, as described above, the water tank is divided into a first sedimentation chamber and a second sedimentation chamber by a partition. The partition includes a first partition and a second partition, and a filter channel for connecting the first sedimentation chamber and the second sedimentation chamber is formed between the first partition and the second partition.

[0013] The water tank is divided into a first sedimentation chamber and a second sedimentation chamber by a partition, and a filter channel is also installed. This allows the wastewater entering the water tank to undergo preliminary sedimentation in the first sedimentation chamber, and then enter the second sedimentation chamber for further sedimentation through the filter channel. This process classifies and settles impurities such as dust in the wastewater, improving the wastewater treatment effect, ensuring the quality of the water used for spraying in the subsequent dust collection pipes, and helping to improve the dust removal effect of the dust removal system.

[0014] Furthermore, as described above, the second sedimentation chamber is provided with a vertically installed filter element and filter screen, and the spacing between the filter element and filter screen forms a drainage chamber for a built-in second water pump within the second sedimentation chamber.

[0015] Vertically installed filter elements and screens are installed in the second sedimentation chamber to further filter the sedimented wastewater, remove fine impurities, and make the water entering the drainage chamber cleaner. This provides cleaner water for the spray heads, reduces clogging, and thus reduces repeated maintenance, thereby improving the dust removal efficiency of the entire dust removal system.

[0016] Furthermore, as described above, one end of the dust collection pipe is connected to the dust removal chamber, and the dust collection pipe is inclined so that the end of the dust collection pipe near the polishing equipment is higher than the end near the wet dust collector. An openable maintenance port is provided on the dust collection pipe.

[0017] The dust collection duct is angled so that the end near the polishing equipment is higher than the end near the wet scrubber. This allows the wastewater formed by the mixture of spray liquid and dust during the spraying process to flow smoothly into the wet scrubber and then through the drain pipe into the water tank for secondary filtration, thus reducing residue in the duct. The inspection port facilitates the inspection and cleaning of the dust collection duct, allowing for the timely removal of any dust or other impurities that may be adhering to the duct, ensuring effective dust extraction and subsequent dust removal.

[0018] Furthermore, as described above, the dust removal chamber is equipped with a liquid level sensor for detecting the liquid level and a pressure sensor for detecting the pressure.

[0019] The liquid level sensor can detect the liquid level of the spraying liquid in the dust removal chamber in real time, ensuring that the liquid level is within a suitable range, guaranteeing the normal operation of the spraying components, and avoiding the impact of excessively high or low liquid levels on dust removal.

[0020] Pressure sensors can detect the pressure inside the dust removal chamber, allowing staff to promptly understand the operating status of the dust removal system, adjust system parameters according to pressure changes, ensure stable system operation, and improve dust removal efficiency.

[0021] The beneficial effects of this utility model are as follows: By connecting the air inlet and outlet on the explosion-proof fan, and the wet dust collector via a connecting pipe to the air inlet, it ensures that the high concentration, small particle size, and highly viscous dust generated during the grinding and polishing process is effectively sucked in and treated. When the explosion-proof fan is driven, the dust generated during the grinding and polishing process is drawn in through the dust suction pipe. As the dust passes through the dust suction pipe, it is sprayed through the spray nozzles for dust removal, reducing dust retention and adhesion in the pipe and ensuring the effective dust extraction of the pipe. Simultaneously, it also reduces the amount of dust in the extracted dust. The first spray dust removal of the dusty gas improves the subsequent dust removal effect. After the dusty gas has undergone the first spray dust removal, it enters the dust removal chamber through the dust suction pipe. The first water pump controls the spray valve to spray the dusty gas a second time to ensure that the dusty gas and the spray liquid are fully mixed, which improves the dust collection efficiency. This solves the problem of insufficient mixing of dust and liquid, which affects the dust removal effect and efficiency. In addition, the dust suction pipe, through the connected drainage pipe, allows the dusty wastewater to enter the water tank for collection and filtration, thereby improving the effect of wet dust removal.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer, the following describes the solution in further detail with reference to the accompanying drawings and embodiments.

They are only for the convenience of describing this scheme and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0030] In this embodiment, refer to Figures 1-4 The present invention relates to a wet dust collection system for grinding and polishing, comprising an explosion-proof fan 1, a wet dust collector 2, and a duct spraying device. The explosion-proof fan 1 is equipped with an air inlet 3 and an air outlet 4. The wet dust collector 2 is connected to the air inlet 3 via a connecting pipe 5. The wet dust collector 2 is also equipped with a suction pipe 6 for connecting to grinding and polishing equipment. The end of the suction pipe 6 away from the wet dust collector 2 has a suction port, and the other end of the suction pipe 6 is connected to the wet dust collector 2. A dust collection chamber 7 is formed within the wet dust collector 2, and a spraying assembly for spraying is installed within the dust collection chamber 7. The spraying assembly includes a first water pump 8 and a spray valve 9. A collection valve is formed at the bottom of the dust collection chamber 7. The collection chamber 10 collects the spray liquid. The spray valve 9 is installed in the dust removal chamber 7 through the mounting bracket 11. The first water pump 8 is connected to the spray valve 9 and the collection chamber 10 through a pipe, so that the first water pump 8 can supply spray liquid to the spray valve 9. The pipeline spray device includes a water tank 12, a second water pump 13 and a spray head 14. The second water pump 13 is connected to the spray head 14 through the spray pipe 15, and the second water pump 13 is connected to the water tank 12 through the water inlet. The spray head 14 passes through the dust suction pipe 6 and is built into the dust suction pipe 6, so that the spray head 14 can cooperate with the suction of the dust suction pipe 6 to spray dust removal. The end of the dust suction pipe 6 near the wet dust collector 2 is provided with a drain pipe 16 connected to the water tank 12.

[0031] The spray valve 9 is provided in two sets, and the two sets of spray valve 9 are arranged vertically at intervals.

[0032] By setting two sets of spray valves 9 spaced apart vertically, the dust entering the wet scrubber 2 can be sprayed from different heights, increasing the spray coverage area, allowing the dust and liquid to mix fully, improving the dust collection efficiency, and thus enhancing the overall dust removal efficiency of the dust removal system.

[0033] The wet dust collector 2 is provided with an air inlet 17 and an exhaust outlet 18 that communicate with the dust collection chamber 7, and a drain valve is provided at the bottom of the wet dust collector 2.

[0034] The air inlet 17 and the exhaust outlet 18 facilitate the entry of dusty gas and the discharge of purified gas. The drain valve at the bottom allows for the easy discharge of dusty wastewater collected in the dust removal chamber 7, ensuring the cleanliness of the dust removal chamber 7, maintaining the normal operation of the dust removal system, and improving the dust removal effect.

[0035] The water tank 12 is divided into a first sedimentation chamber 19 and a second sedimentation chamber 20 by a partition. The partition includes a first partition 21 and a second partition 22. A filter channel 23 for connecting the first sedimentation chamber 19 and the second sedimentation chamber 20 is formed between the first partition 21 and the second partition 22.

[0036] The water tank 12 is divided into a first sedimentation chamber 19 and a second sedimentation chamber 20 by a partition, and a filter channel 23 is provided. This allows the sewage entering the water tank 12 to undergo preliminary sedimentation in the first sedimentation chamber 19, and then enter the second sedimentation chamber 20 through the filter channel 23 for further sedimentation. This process classifies and settles impurities such as dust in the sewage, improves the sewage treatment effect, ensures the quality of the water used for spraying in the subsequent dust collection pipe 6, and helps to improve the dust removal effect of the dust removal system.

[0037] The second sedimentation chamber 20 is provided with a vertically installed filter element 24 and filter screen 25. The gap between the filter element 24 and filter screen 25 forms a drainage chamber 26 for the built-in second water pump 13 in the second sedimentation chamber 20.

[0038] Vertically installed filter elements 24 and filter screens 25 are installed in the second sedimentation chamber 20 to further filter the sedimented wastewater, remove fine impurities, make the water entering the drainage chamber 26 cleaner, provide cleaner spray water for the spray heads 14, reduce the clogging of the spray heads 14, thereby reducing subsequent repeated maintenance and improving the dust removal efficiency of the entire dust removal system.

[0039] Specifically, in this embodiment, the filter element 24 is made of activated carbon.

[0040] One end of the dust collection pipe 6 is connected to the dust removal chamber 7. The dust collection pipe 6 is inclined so that the end of the dust collection pipe 6 near the polishing equipment is higher than the end near the wet dust collector 2. An openable maintenance port 27 is provided on the dust collection pipe 6.

[0041] The dust collection pipe 6 is inclined, so that the end near the polishing equipment is higher than the end near the wet dust collector 2. This allows the wastewater formed after the spray liquid mixes with the dust during the spraying process to flow smoothly to the wet dust collector 2 and enter the water tank 12 through the drain pipe 16 for secondary filtration, thereby reducing residue in the pipe. The inspection port 27 facilitates the inspection and cleaning of the dust collection pipe 6, allowing for the timely removal of dust and other impurities that may adhere to the pipe, ensuring the pipe's suction and dust removal efficiency and subsequent dust removal effect.

[0042] The dust removal chamber 7 is equipped with a liquid level sensor 28 for detecting liquid level and a pressure sensor 29 for detecting pressure.

[0043] The liquid level sensor 28 can detect the liquid level of the spraying liquid in the dust removal chamber 7 in real time, ensuring that the liquid level is within a suitable range, ensuring the normal operation of the spraying components, and avoiding the impact of excessively high or low liquid levels on the dust removal effect.

[0044] Pressure sensor 29 can detect the pressure inside dust removal chamber 7, allowing staff to promptly understand the operating status of the dust removal system, adjust system parameters according to pressure changes, ensure stable system operation, and improve dust removal efficiency.

[0045] Specifically, refer to Figure 4 In this embodiment, multiple dust suction pipes 6 can be provided, thereby connecting the multiple dust suction pipes to the corresponding grinding and polishing equipment to meet dust removal needs.

[0046] The specific wet dust removal process in this embodiment is as follows:

[0047] One end of the dust collection pipe 6 is connected to the grinding and polishing equipment. Driven by the explosion-proof fan 1, the connecting pipe 5 generates negative pressure suction, which allows the dust collection pipe 6 to suck up the dust generated by grinding and polishing through the dust suction port. When the dust-laden gas enters the dust collection pipe 6, the second water pump 13 controls the spray head 14 to spray the dust-laden gas in the dust collection pipe 6 for the first time to remove dust. The dust in the dust-laden gas mixes with the liquid to form sewage, which flows along the inclined dust collection pipe 6 and is discharged from the drain pipe 16. The discharged sewage enters the first sedimentation chamber 19 of the water tank 12 for sedimentation, and then passes through the filter element 24 and filter screen 25 in the second sedimentation chamber 20 before entering the drain chamber 26. This ensures the stable and normal operation of the second water pump 13. At the same time, the spray head 14 can spray and clean the dust collection pipe 6 to reduce dust retention or adhesion to the inner wall of the pipe.

[0048] After the first spray dust removal, the dust-laden gas enters the dust removal chamber 7 through the air inlet 17. At this time, the first water pump 8 controls the spray valve 9 to perform a second spray dust removal on the dust-laden gas, ensuring that the dust-laden gas and the spray liquid are fully mixed, thereby improving the dust collection efficiency. This solves the problem of insufficient mixing between dust and liquid, which affects the dust removal effect and efficiency. The dust removal effect is further improved through the first and second spray dust removal.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
