Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, and in particular to a completely off-line dust removal equipment. Background Art

[0002] Bag pulse dust collector is a dry dust removal equipment, which is divided into online and offline types. Bag pulse dust collector has single or multiple dust chambers. The online dust collector does not cut off the airflow of each dust chamber during the cleaning process. Each dust chamber is in a normal filtering and dust removal state and is cleaned at the same time. The offline dust collector cuts off the airflow in some dust bins during the cleaning process, stops the filtering and dust removal process, and cleans the bags in one dust bin separately. The offline pulse bag dust collector has obvious advantages in dealing with large air volume, high dust concentration and sticky dust.

[0003] Both offline and online dust removal equipment use high-pressure airflow to blow the reverse bags during cleaning. The high-pressure airflow impacts the bags, causing them to shake and shake off the dust on the surface. In order to achieve better cleaning effects, the air pressure of the reverse blowing airflow is usually increased to make the bags shake more violently. However, more violent shaking of the bags will also damage them, which may reduce the service life of the bags to a certain extent. Therefore, in order to ensure the efficiency of cleaning the dust on the surface of the bags while reducing damage to the bags, we have proposed a completely offline dust removal equipment.

[0011] The working principle and beneficial effects of the present invention are: 1. In the present invention, by setting the inner cage and the outer cage of the filter bag, when filtering, the filter cloth bag fits with the inner cage of the filter bag and does not contact with the outer cage of the filter bag. When the filter cloth bag is used for dust removal, the filter cloth bag can contact with the outer cage of the filter bag. When dust and gas are filtered, the filter cloth bag is tightly attached to the inner cage of the filter bag. When the purge mechanism back-blows the filter cloth bag, the filter cloth bag is filled with air, and the filter cloth bag expands and contacts with the outer cage of the crawler. 2. In the present invention, an impact block and a toggle plate are provided. When the flip rod rotates, the toggle plate is driven to rotate. The toggle plate toggles the impact block, causing the spring three to bend. Since the connection between the spring three and the transmission rod is located on the side of the connection between the flip rod and the transmission rod close to the outer cage of the filter bag, the length of the spring three is smaller than the length of the toggle plate. When the toggle plate toggles the spring to bend to a certain angle, the toggle plate will separate from the impact block. At this time, the impact block will hit the transmission rod under the action of the rebound force of the spring three, causing the transmission rod to vibrate, and the transmission rod drives the stick body of the outer cage of the filter bag to vibrate. At this time, the filter cloth bag is tightly attached to the outer cage of the filter bag, and the vibration of the stick body of the outer cage of the filter bag helps to shake off the dust on the surface of the filter cloth bag by the outer cage of the filter bag, so that the filter cloth The dust on the surface of the bag is easier to fall off, thereby ensuring the cleaning effect of the filter cloth bag while reducing the damage to the filter cloth bag. At the same time, when the filter cloth bag hits the outer cage of the filter bag, it also helps the dust on the filter cloth bag to fall off. When the plug is pulled by spring one and fits the docking groove, the flip rod and the transmission rod rotate relative to each other in the opposite directions, and the toggle piece rotates in the direction of the transmission rod. When the toggle piece contacts the impact block, the toggle piece rotates in the deflection groove to squeeze the spring two. After the toggle piece rotates, it slides over the impact block on the side of the impact block. When the toggle piece moves to the side of the impact block close to the transmission rod, the toggle piece rotates and fits the deflection groove under the action of spring two. At this time, the toggle piece can toggle the impact block; 3. In the present invention, by arranging a filtering mechanism, when cleaning the filter bag, air flow will be discharged between the plug and the docking groove, so that the impact force on the filter bag is relatively small. At the same time, the vibration caused by the impact block is transmitted to the outer cage of the filter bag through the transmission rod. Through the vibration of the outer cage of the filter bag and the impact of the filter bag on the outer cage of the filter bag, the dust on the surface of the filter bag can be more easily removed, thereby ensuring the dust removal efficiency while avoiding the filter bag from being subjected to a large air pressure shock.

The exhaust pipe 6 is connected with an exhaust pump for suction. When cleaning the filter bags 10, the filter bags 10 in the three dust gas chambers 4 are cleaned alternately, and one of the lifting valves is closed to stop the air intake in the corresponding dust gas chamber 4. At this time, the purge mechanism back-blows the filter bags 10 for cleaning.

[0017] like Figure 4~Figure 6As shown, the filter bag cage assembly includes a filter bag inner cage 11, a ring plate 12, a filter bag outer cage 13 and a ring plate 2 14. The filter bag inner cage 11 is fixedly connected to the annular boss 9, and the filter cloth bag 10 is sleeved on the filter bag inner cage 11.

When the purge mechanism back-blows the filter cloth bag 10, the filter cloth bag 10 is filled with air, and the filter cloth bag 10 expands and contacts with the track outer cage.

[0018] like Figure 5~Figure 8 As shown, the vibrating dust removal assembly includes a tension frame 15, a docking groove 16, a plug 17 and a spring 18. The tension frame 15 is fixedly connected to the ring plate 12, and the tension frame 15 is arranged on the side of the ring plate 12 close to the annular boss 9. The docking groove 16 is arranged on the side of the ring plate 12 away from the tension frame 15. The plug 17 is slidably connected to the docking groove 16, and the plug 17 and the docking groove 16 are detachably connected. The spring 18 is arranged between the plug 17 and the tension frame 15, and the two ends of the spring 18 are respectively fixedly connected to the plug 17 and the tension frame 15. The spring 18 pulls the plug 17 to connect with the docking groove 16, and then the dust is removed. During air filtering, the plug 17 is tightly attached to the docking groove 16 under the action of the spring 18 and air pressure, and the dust gas enters the clean air chamber 3 after being filtered by the filter bag 10. After the electric-controlled nozzle 30 sprays air into the venturi 29, a large amount of gas enters the filter bag 10, causing the filter bag 10 to expand rapidly. At the same time, under the action of air pressure, the plug 17 is pushed to separate from the docking groove 16, and part of the gas will leave the space inside the filter bag 10 through the gap between the docking groove 16 and the plug 17, reducing the air pressure shock on the filter bag 10, reducing the amplitude of the violent expansion of the filter bag 10, and reducing the damage to the filter bag 10.

[0019] like Figure 6~Figure 8As shown, the center of the stick body constituting the filter bag outer cage 13 is rotatably connected with a transmission rod 19, and a plurality of flip rods 20 are rotatably connected on the side of the plug 17 away from the docking groove 16. The transmission rod 19 corresponds to the flip rod 20 one by one, and the transmission rod 19 is rotatably connected to the flip rod 20. A deflection groove 21 and a toggle piece 22 are provided on the flip rod 20. The deflection groove 21 is opened on the end of the flip rod 20 close to the transmission rod 19, and the toggle piece 22 is rotatably arranged in the deflection groove 21. A spring 23 is arranged between the toggle piece 22 and the deflection groove 21. A spring 3 24 is fixedly connected on the side of the transmission rod 19 close to the flip rod 20, and a collision block 25 is fixedly connected to the spring 3 24. The collision block 25 is arranged on the side of the transmission rod 19 close to the filter bag outer cage 13. 25 can contact with the side of the toggle piece 22 close to the transmission rod 19, the rotation axis direction of the toggle piece 22 is perpendicular to the flip rod 20, and the side of the toggle piece 22 away from the impact block 25 is rotatably connected with the deflection groove 21. In this embodiment, the filter bag inner cage 11 and the filter bag outer cage 13 are both composed of eight stick bodies, and the transmission rod 19 and the flip rod 20 are also provided with eight pairs. When the plug 17 moves downward under the action of air pressure, the flip rod 20 is driven to rotate, and the flip rod 20 rotates relative to the transmission rod 19. Before the plug 17 is separated from the docking groove 16, the toggle piece 22 is on the side of the impact block 25 close to the transmission rod 19. When the flip rod 20 rotates, it drives the toggle piece 22 to rotate, and the toggle piece 22 toggles the impact block 25, causing the spring three 24 to bend. The connection between the spring 24 and the transmission rod 19 is located at the side of the connection between the flip rod 20 and the transmission rod 19 close to the filter bag outer cage 13, so the length of the spring three 24 is smaller than the length of the toggle piece 22. When the toggle piece 22 toggles the spring to bend to a certain angle, the toggle piece 22 will separate from the impact block 25. At this time, the impact block 25 will impact on the transmission rod 19 under the action of the rebound force of the spring three 24, so that the transmission rod 19 vibrates, and the transmission rod 19 drives the stick body of the filter bag outer cage 13 to vibrate. At this time, the filter cloth bag 10 is tightly attached to the filter bag outer cage 13, and the vibration of the stick body of the filter bag outer cage 13 helps to shake off the dust on the surface of the filter cloth bag 10 by the filter bag outer cage 13, so that the dust on the surface of the filter cloth bag 10 is easier to fall off, thereby ensuring the cleaning effect of the filter cloth bag 10 while reducing the The damage of the filter bag 10 and the impact of the filter bag 10 on the outer cage 13 of the filter bag also help the dust on the filter bag 10 to fall off. When the plug 17 is pulled by the spring 18 to fit the docking groove 16, the flip rod 20 and the transmission rod 19 rotate relative to each other in the opposite directions, and the toggle piece 22 rotates in the direction of the transmission rod 19. When the toggle piece 22 contacts the impact block 25, the toggle piece 22 rotates in the deflection groove 21, squeezing the spring 23. After the toggle piece 22 rotates, it slides over the impact block 25 on the side of the impact block 25. When the toggle piece 22 moves to the side of the impact block 25 close to the transmission rod 19, the toggle piece 22 rotates to fit the deflection groove 21 under the action of the spring 23. At this time, the toggle piece 22 can toggle the impact block 25.

[0020] like Figure 1~Figure 4 As shown, the purge mechanism includes a pressure gas tank 26, an electromagnetic gas valve 27, an air guide pipe 28, a venturi tube 29 and an electrically controlled nozzle 30. The pressure gas tank 26 is fixedly mounted on the filter frame 1. A plurality of electromagnetic gas valves 27 are provided. The plurality of electromagnetic gas valves 27 are fixedly mounted on the pressure gas tank 26. The air guide pipe 28 is connected to the electromagnetic gas valve 27.

The plurality of venturi tubes 29 are fixedly mounted on the porous A plurality of electrically controlled nozzles 30 are provided at the through holes on the plate 8. The plurality of electrically controlled nozzles 30 are installed on the air duct 28. The electrically controlled nozzles 30 correspond to the venturi tube 29 one by one. The electrically controlled nozzles 30 are arranged above the venturi tube 29. The electromagnetic valve 27 can control the flow of gas between the pressure gas tank 26 and the air duct 28. The jet to the inside of the venturi tube 29 can be controlled by controlling the electrically controlled nozzles 30. When the electrically controlled nozzles 30 jet to the inside of the venturi tube 29, a large amount of gas will flow into the filter cloth bag 10.

[0021] In this embodiment, the dust gas is introduced into the dust gas chamber 4 through the air supply pipe 7, and the vacuum pump extracts the gas outward through the exhaust pipe 6. The dust-containing gas enters the clean air chamber 3 through the filter bag 10 and then enters the exhaust pipe 6. When the filter bag 10 is dusted, the lifting valve on the exhaust pipe 6 connected to the corresponding dust gas chamber 4 closes the exhaust pipe 6. At this time, the electromagnetic valve 27 is opened, and the electric control nozzle 30 at the corresponding position is opened. The high-pressure gas in the pressure gas tank 26 is sprayed to the venturi 29 through the air guide pipe 28 and the electric control nozzle 30. A large amount of gas flows into the filter bag 10, and the filter bag 10 is quickly opened and connected to the filter bag The outer cage 13 is in contact, and the air pressure pushes the plug 17 to separate from the docking groove 16. The spring 18 is stretched and extended, and the plug 17 drives the flip rod 20 to rotate, and the flip rod 20 drives the transmission rod 19 to rotate. At this time, the toggle piece 22 rotates with the flip rod 20, and the toggle piece 22 toggles the impact block 25, and the spring three 24 bends. When the toggle piece 22 rotates to a certain angle, the toggle piece 22 is separated from the impact block 25, and the spring three 24 drives the impact block 25 to rotate and hit the transmission rod 19. The transmission rod 19 transmits the vibration to the outer cage 13 of the filter bag, and the dust on the filter cloth bag 10 is easier to remove through vibration.

[0022] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
