Description

Technical Field

[0002] In actual waste gas treatment work, after the waste gas has undergone primary dust removal treatment such as dehumidification, it is often involved to use a filter bag dust purifier for purification and dust removal. The filter bag dust removal and purification equipment mainly uses the filter bags in the dust removal box to perform dust removal and filtration work, and the filter bags can be cleaned by pulse wind pressure. When the current filter bag dust removal and purification equipment uses high-pressure wind to clean the filter bags, the wind pressure will affect the smooth air intake of the dust collector and may even easily cause dust backflow.

The filter bag dust collector 3 can filter dust efficiently. At the same time, the present structure utilizes the floating filter part 2 that can be elastically lifted and lowered, in conjunction with the filter bag dust collector 3, and utilizes the poor airflow permeability of the filter bag dust collector 3 after being clogged. It can improve the filtration uniformity of each filter bag dust collector 3, ensure that each filter bag dust collector 3 can be fully utilized, and avoid the problem of low utilization rate of local filter bag dust collector 3 due to restrictions such as air intake position. This structure can be used for areas with severe blockage. The filter bag dust removal part 3 controls its intake flow rate, which can reduce its filtration utilization rate, making it easier for dust gas to adhere to the filter bag 302 with lower utilization rate. This structure can improve the dust adhesion consistency of each filter bag 302 after long-term use, making it easier to replace each filter bag 302 at one time, reducing the replacement frequency and the number of maintenance. At the same time, this structure can automatically control the dust removal consistency of each filter bag 302 by using the intake air pressure, ensuring the consistency of the service life of each filter bag 302, and preventing the local filter bag 302 from being blocked for a long time and the wind from blowing. The problem of the filter bag 302 still being blocked affects the service life of some filter bags 302, and even causes damage. The overall service life of the filter bag 302 is improved. As the service life increases, the air permeability of some seriously blocked filter bags 302 becomes worse. Under the action of the air pressure of the air inlet pipe 1012, the air pressure pushes the filter bag 302, driving the dust filter bracket 301 and the sliding connection cylinder 201 to move upward, compressing the floating spring 202. At this time, as the dust filter bracket 301 moves, the exhaust cover 304 will also be driven to move. When the exhaust cover 304 moves upward, it will move with the airflow through the bottom of the cylinder 105. The distance between the parts is reduced because the passage is narrowed. At this time, the airflow is reduced, and the exhaust gas will pass more through the filter bags 302 that are not seriously blocked, so as to balance the dust adhesion of each filter bag 302 and avoid the filter bags 302 that are seriously blocked from continuing to filter under pressure. The initial distance between the exhaust hood 304 and the bottom of the airflow tube 105 can be adjusted by rotating the threaded connecting column 303. It can be adjusted according to parameters such as the intake pressure, and then the nut on the threaded connecting column 303 is tightened to press against the end of the threaded tube 3011 to fix the threaded connecting column 303 in place. ;

[0040] In the disclosed embodiment, the blockage detection member 4 includes: a detection sliding cylinder 401, an upper electromagnet 402, a micro switch 403 and an anti-mistaken touch spring 404.

The structure does not affect the pulse dust removal and the air intake of the intake pipe 1012, and avoids the strong air pressure of the pulse dust removal causing the intake backflow and blowing up the dust accumulated at the bottom of the purification box 101, which can avoid the need to stop the air intake of traditional pulse dust removal, that is, offline pulse dust removal. The present structure can ensure the air intake efficiency and is more reasonable. The present structure adopts a closed cover 502 to facilitate the staff to replace the dust filter bracket 301 without stopping the machine, which can further improve the practicality of the present structure. The closed cover 502 can automatically seal the bottom of the cylinder 105 after the dust filter bracket 301 is removed, and the micro switch 403 can be used to facilitate the staff to understand each The filter bag 302 is blocked and replaced or pulse dust is removed. When the filter bag 302 is blocked, the upper electromagnet 402 is no longer limited by the closing cover 502. Under the pressure of the anti-mistouch spring 404, the upper electromagnet 402 moves down and no longer presses the micro switch 403. The micro switch 403 will control the corresponding prompt light 102 to light up as a prompt.

The present structure can ensure the discharge quality and is more practical. Five rows of airflows are connected to each other through the cylinder 105. When the nozzle on the pulse exhaust pipe 802 sprays air, the air pressure penetrates the filter bag 302. At this time, the air pressure can press the air pressure slider 602 upward to retract and relieve the pressure.

[0042] In the embodiment of the present disclosure, the discharge member 7 includes: a driving motor 701, a discharge column 702 and a discharge slot 7021. The driving motor 701 is fixedly mounted on the side of the discharge shell 1011; the discharge column 702 is fixedly mounted on the output shaft of the driving motor 701, and three discharge slots 7021 are provided on the discharge column 702; the discharge column 702 rotates to fit the inner side of the discharge shell 1011; the air pressure cleaning member 8 includes: an exhaust hood 801 and a pulse exhaust pipe 802, and a through hole is provided on the top of the exhaust hood 801; the exhaust hood 801 is fixedly mounted on the top of the purification box 101 by bolts; Five pulse exhaust pipes 802 are fixedly installed on the cover 801; the five pulse exhaust pipes 802 are respectively provided with nozzles corresponding to the five rows of dust filter brackets 301; the five pulse exhaust pipes 802 are respectively connected to pulse steam drums; the five pulse exhaust pipes 802 are respectively provided with solenoid valves, and the use of discharge parts 7 can facilitate sealed dust discharge, and can continuously discharge dust without affecting the sealing inside the purification box 101 and the continuous air intake of this structure. At the same time, this structure can use the pulse exhaust pipes 802 to comprehensively clean the five rows of filter bags 302 respectively, and the pulse air pressure dust removal is mature and efficient.

[0043] The working principle of this embodiment is as follows: first, the exhaust pipe of the air intake fan or the exhaust pipe of the exhaust dehumidifier is connected through the air intake pipe 1012, and the exhaust gas is discharged between the bottom of the exhaust isolation plate 104 and the purification box 101, and is filtered through the filter bag 302. The through hole on the top of the exhaust hood 801 is externally connected to the exhaust pipe for conveying the filtered gas. As the use cycle increases, the air permeability of the filter bag 302 that is severely blocked becomes worse. Under the action of the air pressure of the air intake pipe 1012, the air pressure pushes the filter bag 302, drives the dust filter bracket 301 and the sliding connection cylinder 201 to move upward, and compresses the floating spring 202. At this time, as the dust filter bracket 301 When the exhaust hood 304 moves upward, the distance between the exhaust hood 304 and the bottom of the airflow tube 105 is reduced, the airflow here is reduced, and the exhaust gas passes more through the filter bags 302 that are not seriously blocked, so as to balance the dust adhesion of each filter bag 302, and facilitate the subsequent one-time replacement of all the filter bags 302; after the filter bag 302 is blocked, the filter bag 302 is pushed upward by the air pressure, and the exhaust hood 304 is driven to move upward, and the micro switch 403 is also controlled to move upward together. At this time, the upper electromagnet 402 is no longer limited by the closed cover 502, and under the compression of the anti-mistouch spring 404, the upper electromagnet 4 02 moves down, and the micro switch 403 is no longer squeezed. The micro switch 403 will control the corresponding prompt light 102 to light up. When pulse dust removal is needed, first control each row of lower electromagnets 503 and upper electromagnets 402 to be energized and repelled, so as to control the exhaust cover 304 to move up actively. The sealing ring on the outer side of the exhaust cover 304 will directly seal and insert the air flow through the cylinder 105 to ensure the sealing. At this time, the solenoid valves of the five pulse exhaust pipes 802 can be opened, and the nozzles on the pulse exhaust pipes 802 can spray to clean the filter bags 302; using the five rows of air flow through the cylinders 105 respectively connected, the nozzles on the pulse exhaust pipes 802 When the head jets, the air pressure penetrates the filter bag 302. At this time, the air pressure can press the air pressure slider 602 upward. At this time, the air pressure slider 602 pulls the traction rope 6011, pulling the anti-blocking brush 604 to move, which can play the role of moving the brush to wipe the accumulated dust, thereby avoiding the accumulation of dust in the hollow arch and achieving the purpose of breaking the arch.
