[0032] Example
[0033] Reference Figure 1-Figure 7 The utility model provides a technical solution: a bag dust collector that is easy to replace the filter element, including a positioning frame 1 and a pushing mechanism 3, and a processing chamber 2 is fixedly installed inside the positioning frame 1, and the pushing mechanism 3 includes a mounting frame 31, and the mounting frame 31 is slidably installed inside the processing chamber 2. A tooth plate 311 is fixedly installed at the bottom of the mounting frame 31, and a rotating rod 32 is rotatably installed inside the processing chamber 2. The outside of the rotating rod 32 is fixedly connected to a driving gear 321, and the driving gear 321 is meshed with the tooth plate 311. A rotating disk 33 is fixedly installed at one end of the rotating rod 32, and the rotating disk 33 is arranged outside the processing chamber 2.
[0034] In a preferred embodiment, the bottom of the processing bin 2 is fixedly connected to the conical bin 4, the bottom of the conical bin 4 is fixedly connected to the discharge barrel 5, the interior of the discharge barrel 5 is connected to the interior of the conical bin 4, and the interior of the conical bin 4 is connected to the interior of the processing bin 2. This device can not only process the flue gas, but also clean up the impurities accumulated inside the processing bin 2. Therefore, the conical bin 4 is installed at the bottom of the processing bin 2, and the discharge barrel 5 is fixedly installed at the bottom of the conical bin 4. Impurities can enter the interior of the discharge barrel 5 from the interior of the conical bin 4, and the impurities can be discharged from the interior of the discharge barrel 5.
[0035] In a preferred embodiment, the interior of the discharge barrel 5 is rotatably connected to the stirring rod 6, and the outer surface of the stirring rod 6 is fixedly connected to the stirring plate 7. After each flue gas treatment, the interior of the processing chamber 2 can be cleaned, and the filter element is blown by the air pump 14 to blow impurities on the filter element and drop them into the interior of the discharge barrel 5. In order to prevent impurities from accumulating inside the discharge barrel 5 and affecting the falling speed of the impurities, a rotatable stirring rod 6 is installed inside the discharge barrel 5. During the falling process of the impurities, the stirring rod 6 will also rotate simultaneously, which can speed up the falling of impurities from the inside of the discharge barrel 5.
[0036] In a preferred embodiment, a partition 8 is fixedly installed inside the processing chamber 2, one side of the processing chamber 2 is fixedly connected to the air inlet pipe 9, and the other side is fixedly connected to the vacuum fan 10, the air inlet end of the vacuum fan 10 is fixedly connected to the hose 11, one end of the hose 11 is fixedly installed at the top of the processing chamber 2, and the air outlet end of the vacuum fan 10 is fixedly connected to the air outlet pipe 12. In order to improve the treatment effect of the flue gas, the device has a partition 8 fixedly installed inside the processing chamber 2, so that the flue gas can move upward from the bottom end of the processing chamber 2 and pass through all filter elements, thereby improving the treatment effect of the flue gas. In order to speed up the treatment speed of the flue gas, the vacuum fan 10 is used to extract the gas inside the processing chamber 2, thereby speeding up the movement speed of the flue gas in the processing chamber 2 and improving work efficiency.
[0037] After the flue gas is treated by the filter element, the particles in the flue gas will adhere to the filter element. In order to maintain the subsequent treatment effect of the filter element on the flue gas, a detachable top cover 13 is installed on the top of the processing chamber 2, and an air pump 14 is fixedly installed on the top of the top cover 13. A round tube is fixedly installed at the air outlet end of the air pump 14, and one end of the round tube is fixedly connected to the hollow rod 16. A jet pipe 17 is installed at the bottom of the hollow rod 16. In actual use, the air pump 14 can be turned on after the flue gas treatment is completed. The air pump 14 transports the gas to the inside of the hollow rod 16 and disperses it to the inside of each jet pipe 17, and sprays air from the inside of the jet pipe 17 to blow the filter element to blow away the impurities on the filter element, thereby ensuring that the filter element can be used normally.
[0038] The present device pushes the mounting frame 31 upward so that the upper end of the filter element extends out of the interior of the processing chamber 2 so that the staff can take out the filter element. In order to ensure that the staff can stably disassemble and assemble the filter element, it is necessary to ensure that the tooth plate 311 cannot move downward after moving. In order to solve this problem, an anti-rotation mechanism 18 is installed inside the processing chamber 2. The anti-rotation mechanism 18 includes a limit rod 181, a spring 182 and a positioning plate 183. The positioning plate 183 is fixedly mounted on the inner wall of the processing chamber 2. The upper surface of the positioning plate 183 is fixedly connected to the spring 182. One end of the spring 182 is fixedly connected to the limit rod 181. One end of the limit rod 181 is slidably connected to the outside of the tooth plate 311. The outside of the limit rod 181 is rotatably connected to the connecting rod 19. The connecting rod 19 passes through the interior of the processing chamber 2 and extends to the outside of the processing chamber 2. One end of the connecting rod 19 is fixedly connected to the pull plate 15.
[0039] When the tooth plate 311 stops moving, one end of the limiting rod 181 is also in the groove, against the tooth plate 311, thereby controlling the tooth plate 311 not to move downward, and the filter element can be stably disassembled and assembled.
[0040] Specifically, the working process or working principle of a bag filter that is easy to replace the filter element is as follows: when the bag filter is in use, the smoke is transported to the inside of the device and then passes through multiple filter elements. The smoke is processed by the filter elements, and the processed smoke rises to the upper end of the device, and then the processed smoke is extracted for use.
[0041] When a large amount of flue gas enters the equipment and is processed through the filter element, the particles in the flue gas will adhere to the filter element when passing through the filter element. Long-term use will increase the number of particles on the filter element. There are small holes on the filter element. A large number of particles attached to the filter element will block the small holes, causing the filter element to have a poor flue gas treatment effect or even no treatment effect, affecting its use. Therefore, this device is designed to solve this problem.
[0042] The present device can push the filter element out from the interior of the processing chamber 2, and it is convenient to remove the filter element from the interior of the processing chamber 2 so as to replace the filter element and facilitate use. The specific operation is to connect an external power supply. When using the present device, the external flue gas is connected to the air inlet pipe 9 through an external pipe, and the flue gas is transported to the interior of the processing chamber 2. The vacuum pump 10 must also be turned on. Under the action of the vacuum pump 10, a large amount of smoke will be quickly moved inside the processing chamber 2, so that the smoke can pass through the position of the filter element in time to realize smoke treatment and make the particles adhere to the filter element.
[0043] When the flue gas is transported to the interior of the processing chamber 2, the flue gas will be blocked by the partition 8. At this time, a large amount of flue gas will pass through the bottom of the partition 8 and move to the position of the filter element. Under the continuous extraction of the vacuum fan 10, the flue gas under the filter element will move upward rapidly. The flue gas can be processed while passing through the filter element, and the particles in the flue gas will adhere to the filter element. The gas moved to the top of the filter element will be sucked out of the interior of the processing chamber 2 under the pumping of the vacuum fan 10. In actual use, the gas can be collected and used or directly discharged into the atmosphere.
[0044] After the flue gas treatment is completed, the air pump 14 can be turned on, and the gas can be quickly transported to the inside of the hollow rod 16 and then into the inside of the jet pipe 17 through the air pump 14. There are several jet pipes 17 corresponding to the position of each filter element. The particles attached to the filter element are blown off by the jet pipe 17, and fall downward from the inside of the processing bin 2, and fall into the inside of the conical bin 4 and randomly fall out from the inside of the discharge barrel 5. The downward blowing of the jet pipe 17 will also blow the stirring rod 6 to rotate. The continuous rotation of the stirring rod 6 can prevent the particulate impurities from being blocked in the inside of the discharge barrel 5, and can make the particulate impurities fall quickly.
[0045] After long-term use of the filter element, a large amount of particles will adhere to its outer surface. The accumulation of particles on the filter element will affect the filter element's treatment effect on flue gas, so the filter element needs to be replaced regularly. In order to facilitate the replacement of the filter element, the top cover 13 is removed from the top of the processing chamber 2 before replacing the filter element, so that the top of the processing chamber 2 is in an open state, and then the rotating disk 33 is rotated. The device arranges the rotating disk 33 in pairs, and a staff member can simultaneously control the rotation of the two rotating disks 33, one rotating disk 33 rotates clockwise and the other rotates counterclockwise. By controlling the rotation of the rotating rod 32, the driving gear 321 on the rotating rod 32 is driven to rotate, thereby driving the tooth plate 311 to move upward, and the upper end of the mounting frame 31 is pushed out from the interior of the processing chamber 2. At this time, the upper end of the filter element will extend out of the interior of the processing chamber 2, and then the staff will take out the filter element from the interior of the mounting frame 31, replace it with a new filter element and reinstall it.
[0046] After the mounting bracket 31 is pushed to move by the movement of the toothed plate 311, the staff will release the control of the rotating disk 33. At this time, in order to prevent the toothed plate 311 from moving downward under the weight of the mounting bracket 31 and drive the driving gear 321 to rotate, a limiting rod 181 is installed on one side of the toothed plate 311, and one end of the limiting rod 181 is attached to the outer surface of the toothed plate 311. When the toothed plate 311 moves upward, one end of the limiting rod 181 will slide on the outside of the toothed plate 311, and one end of the limiting rod 181 will slide through the grooves on the toothed plate 311 one by one, and one end of the limiting rod 181 will also extend into the inside of the groove. That is, when the toothed plate 311 stops moving, one end of the limiting rod 181 is also in the inside of the groove, against the toothed plate 311.
[0047] Therefore, when the staff releases the control of the rotating disk 33, the tooth plate 311 will not move downward, so that the tooth plate 311 is positioned at a certain position and then the mounting frame 31 is controlled to stably extend out of the processing chamber 2, which is convenient for removing the filter element and replacing it. After replacing the filter element, the connecting rod 19 is pulled, and the movement of the connecting rod 19 will drive the limit rod 181 to move, and one end of the limit rod 181 is pulled out from the groove on the tooth plate 311. At this time, the mounting frame 31 will move downward under the action of its own weight and move back to the initial position. Then the top cover 13 is restored and fixed, so that the device can be used normally again.
[0048] It should be noted that the vacuum fan 10 and the air pump 14 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
