When in use, compressed air is used to blow the residual dust on the filter bag to achieve the purpose of cleaning. After cleaning, there will still be some residual dust attached to the filter bag, which will affect the filtering effect of the filter bag, and when in use, it generally does not have the function of automatic dust discharge. When used for a long time, a large amount of dust is likely to accumulate in the equipment. If manual cleaning is used, it will consume a lot of time and energy of the staff. At the same time, in order to solve the above technical problems, we have designed a high-efficiency pulse bag dust removal system for raw materials entering the furnace for yellow phosphorus production.

The top of the long hollow bracket plate 12 is connected and installed with a long hollow air outlet spray plate 14. The right side of the dust removal box 1 is fixedly connected to an air inlet box 15, and the top of the air inlet box 15 is fixedly connected to an air pump 18.

[0024] See also Figure 1 , Figure 4 and Figure 5 The air outlet end of the vacuum pump 18 is connected to the long hollow bracket plate 12, the inner cavity of the air inlet box 15 is laterally fixedly connected with a filter plate 17, the front and rear sides of the air inlet box 15 are inlaid with filter screens 16, and both sides of the top of the threaded block 13 are fixedly connected with limit blocks.

[0025] See also Figure 1 and Figure 6 The discharge assembly 7 includes a guide frame 19, which is fixedly installed at the bottom of the dust removal box 1. Both sides of the guide frame 19 are connected with a discharge pipe 20, and a closed baffle 21 is installed on the top of the discharge pipe 20. A second motor 22 is fixedly connected to the left side of the dust removal box 1, and the output end of the second motor 22 penetrates into the inner cavity of the dust removal box 1 and is fixedly connected to a bidirectional screw 23. The surface thread sleeve of the bidirectional screw 23 is provided with a threaded scraper 24, and the number of the threaded scrapers 24 is two.

[0026] See also Figure 1 and Figure 6 The inner cavity of the guide frame 19 is laterally fixedly connected with a limiting guide rod, the threaded scraper 24 is movably sleeved on the surface of the limiting guide rod, and the top of the closed baffle 21 is fixedly connected with a handle.

[0027] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The four corners of the bottom of the dust removal box body 1 are fixedly connected with support legs, the front and rear sides of the bottom of the inner cavity of the dust removal box body 1 are fixedly connected with guide blocks, and the inner cavity of the dust removal box body 1 is laterally fixedly connected with a baffle.

[0028] By setting a guide block, the fallen dust can be guided so as to introduce the dust into the guide frame 19. By setting a limiting guide rod, the threaded scraper 24 can be guided and limited to prevent the threaded scraper 24 from rotating during movement. By setting a closed baffle 21, the discharge pipe 20 can be closed to prevent dust from floating out of the dust removal box 1 during use. By setting supporting legs, the equipment can be supported so that the equipment can be placed. By fixing the slide rail 10 and connecting the slide frame 11, the long hollow bracket plate 12 can be installed and the long hollow bracket plate 12 can be moved back and forth. By matching the filter plate 17 and the filter net 16, the dust in the air can be filtered so that external dust can enter the dust removal box 1.

[0029] During use, when producing yellow phosphorus, the flue gas in the furnace will transport the smoke to the dust removal box 1 through the air inlet pipe 3. After the smoke enters the dust removal box 1, the smoke will enter the dust removal bag 4, so that the dust removal bag 4 can filter the dust in the smoke. When the dust removal bag 4 filters the smoke, the user starts the pulse dust collector 5 through an external controller, and then the pulse dust collector 5 can blow air into the dust removal bag 4 in the form of air waves, so that the dust removal bag 4 vibrates, thereby shaking off the dust on the surface. After the dust removal bag 4 filters the smoke, the user controls the first motor 8, and then the output end of the first motor 8 drives the threaded block 13 to move through the threaded rod 9, and the threaded block 13 drives the long strip hollow bracket plate 12 when moving. The hollow air outlet spray plate 14 moves. When the long hollow air outlet spray plate 14 moves, the user starts the vacuum pump 18 so that the long hollow air outlet spray plate 14 can blow air to the surface of the dust bag 4 to blow off the residual dust on the surface of the dust bag 4. When the equipment is working, the staff will regularly clean the dust in the equipment, and then the user will move the recovery device to the bottom of the discharge pipe 20 or sleeve it on the discharge pipe 20, and then pull the closed baffle 21 out of the discharge pipe 20. After completion, the user will start the second motor 22, and then the second motor 22 will drive the two threaded scrapers 24 to move in the opposite direction through the bidirectional screw 23, so as to push the accumulated dust into the discharge pipe 20, so that the dust can fall into the recovery device, so that the staff can handle the dust.
