Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, and in particular to a jet cleaning device for a bag filter dust collector that provides rapid dust removal. Background Technology

[0002] The working principle of a baghouse dust collector is based on the filtration of dust-laden gas by a filter material (usually a filter bag), trapping dust particles on the surface of the bag to achieve air purification. The core component of this type of baghouse dust collector is the filter bag, which is made of woven fiber materials such as polyester fiber or glass fiber, possessing good filtration effect and a certain mechanical strength. Currently, the most common type of baghouse dust collector is the pulse jet baghouse dust collector. This pulse jet baghouse dust collector is an improvement on the traditional baghouse dust collector, retaining the advantages of high purification efficiency, large gas handling capacity, stable performance, convenient operation, long filter bag life, and low maintenance workload. It uses a pulse jet cleaning system to rapidly blow dust particles from the filter bag, thus achieving a rapid dust removal effect.

[0003] However, it has been found that the pulse jet cleaning system in traditional pulse jet baghouse dust collectors has nozzles for spraying high-speed, high-pressure jet airflow. When the pulse jet cleaning system is not in use, if the dust gas entering the dust collector contains heavy moisture, it will cause damp dust inside the dust collector. This dust can easily enter the nozzles, causing them to become clogged and affecting normal pulse jet cleaning operation.

[0004] Therefore, it is necessary to provide a new fast dust removal bag filter pulse jet cleaning device to solve the above-mentioned technical problems. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1-8 The rapid dust removal bag filter pulse jet device includes: an upper housing 1 and a dust discharge hopper 2 connected by bolts. An air inlet pipe connector is fixedly installed on one side of the upper housing 1, an exhaust pipe is fixedly installed on the top of the upper housing 1, and a dust discharge pipe with a dust discharge valve is fixedly installed at the bottom of the dust discharge hopper 2. An mounting plate 3 is fixedly installed inside the upper housing 1, on which multiple filter bags 4 are fixedly installed. An air compressor 5 is fixedly installed on one side of the outer wall of the upper housing 1. An air vent pipe 6 is fixedly installed on the air compressor 5 through a pipeline. Multiple air outlet pipes 7 are fixedly installed on the air vent pipe 6. The ends of the multiple air outlet pipes 7 extend into the upper housing 1. The air outlet pipes 7 are located above the filter bags 4. Each of the multiple air outlet pipes 7 is equipped with a pulse valve 8. Multiple nozzles 9 are fixedly installed at the bottom of the multiple air outlet pipes 7. The multiple nozzles 9 are respectively adapted to the multiple filter bags 4.

[0025] To provide a protective seal for the nozzle 9 when dust removal is not performed, a first movable opening 10 is provided on the side of the upper housing 1 away from the air compressor 5. A rodless cylinder 13 is fixedly installed on the outer wall of the upper housing 1 away from the air compressor 5. A connecting strip 14 is fixedly installed on the slider of the rodless cylinder 13, and a first baffle plate 15 is fixedly installed at the bottom of the connecting strip 14. The first baffle plate 15 contacts one side of the upper housing 1, and its outer dimensions are larger than the diameter of the first movable opening 10, thus sealing the first movable opening 10. Furthermore, to prevent the first movable opening 10 from being exposed when the first baffle plate 15 moves horizontally, its length is set to be longer to allow for normal horizontal movement. A second baffle plate 17 is slidably provided on one side of the first baffle plate 15. The baffle plate 15 has a second movable opening 16, which is connected to the first movable opening 10. The outer dimensions of the second baffle plate 17 are larger than the diameter of the second movable opening 16, thus blocking the second movable opening 16. Furthermore, the height of the second baffle plate 17 is much greater than the diameter of the second movable opening 16, so that the second movable opening 16 will not be exposed when sliding up and down. The upper housing 1 has multiple connecting strips 11, and the bottom of each of the multiple nozzles 9 is in contact with the corresponding connecting strip 11. One side of each of the multiple connecting strips 11 passes through the first movable opening 10 and the second movable opening 16 and is fixedly connected to the second baffle plate 17. Multiple filling columns 12 are fixedly installed on the top of each of the multiple connecting strips 11, and the multiple filling columns 12 are located inside the multiple nozzles 9, thus providing sufficient protection for the nozzles 9.

[0026] In the above method, to facilitate the removal of the filling column 12 from the nozzle 9, a connecting protrusion 18 is fixedly installed on the side of the second shielding plate 17 away from the first shielding plate 15. A folding plate 19 is fixedly installed at the bottom of the first shielding plate 15. Two guide rods 20 are slidably installed on the folding plate 19. The top ends of the two guide rods 20 are fixedly connected to the connecting protrusion 18, and the same abutment strip 22 is fixedly installed at the bottom of the two guide rods 20. An electric push rod 23 is fixedly installed on the folding plate 19, and its output shaft passes through the bottom of the folding plate 19 and is movably connected to the bottom of the folding plate 19. The output shaft of the electric push rod 23 is connected to the abutment strip 22. The connecting bar 11 is adapted to the contact bar 22. When the output shaft of the electric push rod 23 extends and contacts the contact bar 22, it can drive the connecting bar 11 downward, thereby bringing the filling column 12 out of the nozzle 9. In addition, a return spring 21 is sleeved on both guide rods 20. The top end of the return spring 21 is fixedly connected to the connecting protrusion 18, and the bottom end of the return spring 21 is fixedly connected to the bottom inner wall of the folding plate 19. When the connecting bar 11 descends, the return spring 21 is in a compressed state. When the output shaft of the electric push rod 23 gradually retracts, the return function of the return spring 21 automatically re-inserts the filling column 12 into the nozzle 9.

[0027] The working principle of the rapid dust removal bag filter jet cleaning device provided by this utility model is as follows:

[0028] In the initial state, the multiple nozzles 9 are protected by the connecting strip 11 below and the filling column 12 inserted inside the nozzles 9, which prevents moisture and dust from entering and clogging the nozzles when they are not in use.

[0029] During normal use, dusty gas is discharged into the upper chamber 1 through the air inlet pipe joint, and then filtered by the filter bag 4 to obtain relatively clean gas, which is then discharged through the exhaust pipe.

[0030] In subsequent use, when the filter bag 4 needs to be cleaned and dust removed, the output shaft of the electric push rod 23 is first extended. When the output shaft contacts the abutment strip 22, it will push the abutment strip 22, causing it to descend along with the guide rod 20. This will then bring down the second baffle plate 17 and multiple connecting strips 11. After the output shaft of the electric push rod 23 extends to its maximum length, multiple filling columns 12 will be moved out of the corresponding nozzles 9. At this time, the reset spring 21 is in a deeply compressed state. Then, the rodless cylinder 13 is activated, and the slider on it moves the connecting strip 14 longitudinally and horizontally, thereby moving multiple connecting strips 11 longitudinally. This allows the connecting strips 11 to move away from directly below the nozzles 9, so that there is no longer any obstruction below the nozzles 9.

[0031] Then, by opening the pulse valve 8, high-speed and high-pressure airflow can be introduced into multiple air pipes 7 and finally sprayed out through the nozzle 9, thereby enabling rapid jet dust removal of the filter bag 4.

[0032] After dust removal is completed, the rodless cylinder 13 is activated first, and its slider brings the connecting strip 11 back to the bottom of the nozzle 9. Then, the output shaft of the electric push rod 23 is retracted. During the retraction, the compressed return spring 21 is pulled back, which causes the multiple connecting strips 11 to gradually rise, and finally the connecting strips 11 are brought back into contact with the bottom of the nozzle 9. At the same time, the filling column 12 is inserted into the nozzle 9, thus forming a shielding and protection for the nozzle 9 again.

[0033] Compared with related technologies, the fast dust removal bag filter jet cleaning device provided by this utility model has the following beneficial effects:

[0034] This utility model provides a fast dust removal bag filter jet cleaning device. By setting a connecting strip 11 that contacts the bottom of the nozzle 9 and a filling column 12 that can be inserted into the nozzle 9, a good shielding and protection effect can be formed on the nozzle 9 without the filter bag 4 being jet cleaned. This can prevent the nozzle 9 from becoming blocked, ensure that the jet cleaning dust removal work can be carried out normally, and reduce the equipment failure rate.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
