Description

Technical Field

[0001] This utility model relates to the field of sandblasting room technology, and in particular to a sandblasting room exhaust pipe device. Background Technology

[0002] Industry Status and Demand Background: In industries such as shipbuilding, construction machinery, and metal product processing, sandblasting is a core step in surface treatment. High-speed jetting of abrasives such as quartz sand and steel shot effectively removes oxide scale, rust, and burrs from the workpiece surface. However, this process generates a large amount of dust-laden exhaust gas, characterized by: high dust concentration (up to several thousand milligrams of suspended particulate matter per cubic meter of air, mainly composed of silicates, metal oxides, and unbroken abrasives); complex particle size distribution (encompassing large particles from tens of micrometers to submicron-sized fine dust); and high temperature and humidity (frictional heat causes airflow temperature to rise, and in some cases, oily pollutants volatilize). Traditional solutions often employ a "direct discharge + simple bag filter" model, which has significant drawbacks: rapid equipment wear (hard particles continuously scour the inner wall of the pipe, causing wear on the fan impeller and perforation of the filter bags); significant safety hazards (aluminum-magnesium alloy dust poses an explosion risk, and static electricity accumulation may lead to combustion and explosion accidents); and serious resource waste (unrecovered precious metal abrasives are directly discharged, increasing enterprise operating costs).

[0003] Currently, sandblasting booths generally use single bag filters or simple cyclone separators to treat exhaust gas, which has the following shortcomings: incomplete coarse filtration; large abrasive particles easily clog pipes; high escape rate of fine dust; serious waste of water resources; lack of recycling mechanism; high water consumption and frequent maintenance; poor adaptability; inability to adjust spray angle and intensity according to changes in working conditions; risk of secondary pollution; and failure to consider the convenience of operation after wet dust removal. Therefore, we propose a sandblasting booth exhaust stack device to solve this problem. Utility Model Content

The worm gear 25 meshes with the worm gear 27, allowing for precise control of the water mist coverage area.

[0026] In this embodiment, the second filter assembly includes: a limiting block 15 and a clamping plate 19. The clamping plate 19 is fixedly installed on the top of the limiting block 15. A rotating block 16 is fixedly installed on one side of the clamping plate 19. A clamping plate 21 is rotatably installed on the rotating block 16. Multiple limiting pins are fixedly installed on one side of the clamping plate 21. A filter screen 20 is provided between the clamping plate 19 and the clamping plate 21. The clamping plate 19 has a fixing groove that matches the multiple limiting pins. The filter box 4 has an installation groove that matches the clamping plate 19, the clamping plate 21, and the limiting block 15 for further filtration.

[0027] In this embodiment, a circular block 17 is rotatably installed inside the limiting block 15. Two connecting rods 32 are rotatably installed on one side of the circular block 17, and a connecting rod 33 is rotatably installed on one side of the connecting rods 32. A square plate 34 is fixedly installed at the bottom of the connecting rod 33, and a spring 35 is fixedly installed on one side of the square plate 34. A square slot matching the connecting rod 33 is opened in the mounting groove. A square groove matching the square plate 34 is opened in the limiting block 15. The spring 35 is fixedly installed in the square groove and can be precisely adjusted. T-shaped strips 8 are integrally formed on both sides of the water tank 3. A sliding groove matching the T-shaped strips 8 and the water tank 3 is opened in the settling tank 2. A limiting groove matching the connecting rods 32 and 33 is opened in the limiting block 15, which facilitates disassembly and installation.

[0028] In this embodiment, a square groove matching the swing frame 30 is provided in the mounting block 10. A second motor 22 is fixedly installed on one side of the square groove. The output end of the second motor 22 is fixedly connected to the swing frame 30. A third motor 24 is fixedly installed on one of the fixed blocks 23. The output end of the third motor 24 is fixedly connected to the worm gear 25. A rotating rod 18 is fixedly installed on the rotating block 16. The rotating rod 18 is rotatably connected to the clamping plate 21 for quick installation and disassembly. An mounting plate 11 and activated carbon 14 are fixedly installed in the exhaust pipe 25. The activated carbon 14 is located below the mounting plate 11. A first motor 12 is fixedly installed on the mounting plate 11. An exhaust fan 13 is fixedly installed at the output end of the first motor 12 to further adsorb organic waste gas.

[0029] In this embodiment, during use, the water pump 6 is turned on, and the water pump 6 draws water from the water tank 3 through the water pipe 7. The water passes through the folded pipe 29 and is sprayed out from the atomizing nozzle 9 to form water mist. The water mist is used to perform preliminary settling treatment on the dust-laden gas entering the settling tank 2 from the exhaust pipe 1, so that larger dust particles settle into the water tank 3 with the water mist. At the same time, the motor 24 is started, driving the worm 25 to rotate. Since the worm 25 meshes with the worm wheel 27, the worm wheel 27 will rotate accordingly. The round rods 26 on both sides of the worm wheel 27 rotate, driving the strip plate 28 to swing, thereby causing the bottom of the strip plate 28 to swing. The angle of the atomizing nozzle 9 at the end changes. By controlling the forward and reverse rotation of motor 3 24, the atomizing nozzle 9 can be adjusted to a suitable spray angle to better settle the dust-laden gas. At the same time, motor 22 can also be started. Motor 22 drives the swing frame 30 to swing in the square groove at the bottom of the mounting block 10, which helps to adjust the overall position of the atomizing nozzle 9 and further optimize the settling effect. The gas enters the filter box 4. After the gas has undergone preliminary settling treatment in the settling box 2, it enters the filter box 4 through the pipeline. The filter screen 20 is placed between the clamping plate 1 19 and the clamping plate 2 21. The multiple limiting pins on clamping plate 21 are inserted into the corresponding fixing slots on clamping plate 19 to initially fix the filter screen 20. Then, the limiting block 15, clamping plate 19, clamping plate 21, and filter screen 20 are placed into the mounting slot inside the filter box 4. The circular block 17 is rotated, which drives the two connecting rods 32 to rotate. The connecting rods 32 drive the connecting rod 33 to move. When the connecting rod 33 moves to the square slot position in the mounting slot, the square plate 34 pops out and is inserted into the square slot under the action of spring 35, thereby fixing the limiting block 15. The filter screen 20 is fixed in the installation slot to further ensure the stability of the installation. When the gas passes through the filter screen 20, the fine dust and other impurities are filtered out. After being filtered by the filter box 4, the gas enters the exhaust pipe 2 5. When it passes through the activated carbon 14 below the installation plate 11, the activated carbon 14 adsorbs the odors and harmful gases in the gas, further purifying the gas. The motor 12 on the installation plate 11 is turned on, and the motor 12 drives the exhaust fan 13 to rotate, and the purified gas is discharged to the outside through the exhaust pipe 2 5, completing the entire sandblasting process of the sandblasting room exhaust pipe.
