[0026] The filter assembly 5 includes a filter screen 8 installed on one end of the inner wall of the air outlet 3 and a mesh cylinder 9 inserted into the inner wall of the air outlet 3. The mesh cylinder 9, filter media 10 and threaded plate 11 in the air outlet 3 cooperate with each other to filter and adsorb air, further improving cleaning accuracy and efficiency.
[0027] The inner wall of the screen cylinder 9 is provided with filter media 10. One end of the inner wall of the screen cylinder 9 is threadedly connected with a threaded plate 11. The outer wall of the screen cylinder 9 is slidably connected to the inner wall of the air outlet 3. After removing the installation tube 12, the screen cylinder 9 can be taken out from the inside of the air outlet 3 through the threaded plate 11. After opening the threaded plate 11, the outer wall of the screen cylinder 9 and the filter media 10 can be replaced and cleaned, which is convenient for cleaning, easy for installation and assembly, and improves the processing efficiency and accuracy.
[0028] An installation pipe 12 is installed on the outer wall of one end of the air outlet 3, and a fan 13 is installed on the outer wall of one end of the installation pipe 12. The outer wall of the threaded plate 11 has micro-holes distributed at equal intervals.
[0029] The fan 13 is connected to the switch via a wire, and the switch is connected to the power supply via a wire.
[0030] Example 2:
[0031] Reference Figure 1-3 The filter assembly 2 6 includes an insertion hole 14 opened at one end of the top outer wall of the sealing plate 2 and a sealing strip 15 that is inserted into the insertion hole 14. An insertion hole 16 is opened on the inner wall of the treatment box 1 at the air outlet 3. An insertion plate 17 is welded to the center of the bottom outer wall of the sealing strip 15. The two outer walls of the insertion plate 17 are slidably connected to the outer walls of the air outlet 3 and the insertion hole 16. The sealing plate 2 is removed from the outer wall of the treatment box 1, the outer wall of the partition plate 19 is cleaned, and water is added to the inner wall of the treatment box 1 through the addition pipe 21 to facilitate cleaning of the inside of the treatment box 1 and make it easy to use.
[0032] The plug plate 17 is removed upward from the sealing plate 2 by the sealing strip 15. The outer wall of the plug plate 17 slides on the outer wall of the scraper 18, and the particles and dust intercepted by the outer wall of the plug plate 17 are hung down. The dust and particles fall into the water, which is convenient for subsequent centralized treatment.
[0033] A scraper 18 is installed on the bottom outer wall of the sealing plate 2 at the insertion plate 17. One side of the outer wall of the scraper 18 is in contact with one side of the outer wall of the insertion plate 17. The outer wall of the insertion plate 17 has through holes that are evenly distributed at the air outlet 3. The insertion plate 17 and the filter screen 8 filter and intercept the gas at one end of the air outlet 3. After the insertion plate 17 is removed from the insertion hole 14, it can be cleaned by the scraper 18, which facilitates interception, improves processing accuracy, and facilitates cleaning.
[0034] A partition plate 19 is welded to the center of the bottom outer wall of the sealing plate 2. The two outer walls of the partition plate 19 are slidably connected to the inner wall of the treatment box 1. An air inlet pipe 20 is connected to the top outer wall of the sealing plate 2. The partition plate 19 in the treatment box 1 disrupts the direction of airflow, making it easier for impurities in the airflow to interfere with each other, so that some impurities fall directly into the water, and some dust and impurities will adhere to the outer wall of the partition plate 19 for easy interception and treatment of dust and particles in the air.
[0035] Filter assembly 37 includes a cleaning port located on the outer wall of one side of the treatment box 1 at the drain pipe 4 and a filter pipe 23 inserted into the inner wall of the treatment box 1 at the cleaning port;
[0036] A sealing circular plate 24 is welded to the outer wall of one end of the filter tube 23. The outer wall of the sealing circular plate 24 is threadedly connected to the inner wall of one end of the cleaning port. An adding pipe 21 is connected to the middle of the outer wall of one side of the treatment box 1. A valve 22 is installed at one end of both the adding pipe 21 and the drain pipe 4. After use, the valve 22 of the drain pipe 4 is opened to drain the water inside the treatment box 1. After the water is drained, the impurities and particles in the water are intercepted by the filter tube 23. The filter tube 23 is removed from one end of the drain pipe 4 through the sealing circular plate 24. The impurities and particles in the filter tube 23 are centrally processed for subsequent cleaning.
[0037] Working principle: During use, the air inlet pipe 20 at the top of the processing box 1 is installed in the crushing or pulverizing equipment. Water is added to the inside of the processing box 1 through the adding pipe 21, with the water level below the bottom of the partition plate 19. The blower 13 is started through the installation pipe 12 and draws gas from the inside of the processing box 1. The processing box 1 draws air from the inside of the crushing equipment through the air inlet pipe 20, drawing the dust and waste from the crushing process into the processing box 1. The dust and debris entering the processing box 1 move downwards under the obstruction of the partition plate 19, and most of the debris and dust are separated. Dust will come into contact with the water at the bottom of the processing tank 1. After contact, the weight of the debris and dust will increase, causing the debris and dust to fall into the water. Other debris and dust will reach the air outlet 3 with the gas. The plug plate 17 and the filter screen 8 will intercept the gas in a double manner, trapping all impurities on the outer wall of the plug plate 17. Then the gas and a small amount of dust will enter the air outlet 3. The remaining dust will be intercepted and adsorbed by the screen cylinder 9, filter material 10 and threaded plate 11. After that, the treated gas will be discharged from the blower 13, which will facilitate the processing of the crushing process.
[0038] After use, open valve 22 of drain pipe 4 to drain the water inside treatment tank 1. After the water is drained, impurities and particles in the water are intercepted by filter pipe 23. The filter pipe 23 is removed from one end of drain pipe 4 through sealing round plate 24. The impurities and particles in filter pipe 23 are centrally processed for easy subsequent cleaning.
