Description

Technical Field

[0001] The utility model generally relates to the field of dust removal equipment, and particularly relates to a bag filter. Background Art

[0002] A bag filter is an efficient dry dust filtering device, which is widely used in the industrial field and plays an important role especially in dust emission control. Its working principle is to use a bag-type filtering element made of fiber fabric to capture solid particles in the dust-containing gas, so as to separate the dust from the gas. The filter bag is cleaned by injecting gas through a pulse tube to prevent the filter bag from being blocked by solid particles. The pulse tube is usually arranged in the upper box body. In order to facilitate the disassembly and assembly of the filter bag, a cover plate that can be opened is usually arranged on the top of the upper box body.

[0003] In the prior art, the upper box body and the main box body are generally fixed and cannot be disassembled. When disassembling and assembling the filter bag, the disassembly and assembly route may be blocked by the pulse tube, resulting in inconvenient disassembly and assembly.

It can be understood that the specific embodiments described herein are only used to explain the relevant utility model and are not intended to limit the utility model. Additionally, it should be noted that for ease of description, only the parts related to the utility model are shown in the drawings.

[0019] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will detail the present application with reference to the accompanying drawings and embodiments.

[0020] Please refer to Figures 1 to 7 , the bag filter of the present utility model includes: a main box body 100, a hopper 110 is provided at the bottom thereof, a plurality of filter bags 120 are provided at the top of the main box body 100, an air inlet 111 is provided at one side of the hopper 110, and a gas cylinder 200 is detachably and fixedly connected to the outside of the main box body 100; an upper box body 300, which is detachably and sealingly fixedly connected to the top of the main box body 100, a cover plate 310 is detachably and sealingly fixedly connected to the top of the upper box body 300, a plurality of pulse tubes 320 are detachably fixedly connected inside the upper box body 300, the plurality of pulse tubes 320 are respectively communicated with the gas cylinder 200, and an air outlet 330 is provided at one side of the upper box body 300; a dust collection bucket 400, which is detachably connected to the bottom of the hopper 110, and a valve 410 is provided between the dust collection bucket 400 and the bottom of the hopper 110.

[0021] In an embodiment of the present utility model, the dust-containing gas enters the main box body 100 from the air inlet 111. After being filtered by the filter bag 120, the dust remains on the surface of the filter bag 120, achieving the separation of dust and gas. The filtered gas enters the upper box body 300 and is then discharged from the air outlet 330. After the bag filter works for a period of time, the pulse tube 320 sprays pulse gas to clean the dust on the surface of the filter bag 120. The dust separated from the filter bag 120 will fall into the ash hopper 110 and then enter the ash collection bucket 400. The ash collection bucket 400 can collect the fallen dust. A valve 410 is provided between the ash collection bucket 400 and the bottom of the ash hopper 110. During the normal operation of the bag filter, the valve 410 is in an open state, and the dust can fall into the ash collection bucket 400. When there is a large amount of dust in the ash collection bucket 400 and needs to be cleaned, the valve 410 is switched to the closed state to separate the ash collection bucket 400 from the bottom of the ash hopper 110. A new ash collection bucket 400 is replaced, or after the old ash collection bucket 400 is cleaned, it is fixed to the bottom of the ash hopper 110, and then the valve 410 is opened. The bag filter can clean the ash collection bucket 400 without stopping the machine.

[0022] A plurality of filter bags 120 are provided at the top of the main box body 100, which can ensure the filtering efficiency of the bag filter for gas. Multiple pulse tubes 320 are respectively connected to the gas cylinder 200, and the gas cylinder 200 can store pulse gas. Of course, the connection between the multiple pulse tubes 320 and the gas cylinder 200 is separable.

[0023] The upper box body 300 is detachably and sealingly fixedly connected to the top of the main box body 100 to prevent gas from leaking between the upper box body 300 and the main box body 100. A plurality of pulse tubes 320 are detachably fixedly connected inside the upper box body 300. When disassembling and assembling the filter bag 120, the upper box body 300 can be separated from the main box body 100, and the upper box body 300 will drive the multiple pulse tubes 320 to move, avoiding the pulse tubes 320 blocking the disassembly and assembly route and making the disassembly and assembly more convenient.

[0024] Furthermore, a plurality of lock plates 340 are respectively fixedly connected to each side of the cover plate 310. The lock plates 340 are provided with lock grooves 341. A plurality of lock catches 350 are rotatably connected to the upper box body 300. The lock catches 350 correspond to the lock plates 340 one by one. Part of the lock catches 350 is placed into the lock grooves 341 to lock the cover plate 310 on the upper box body 300.

[0025] In an embodiment of the present utility model, when the bag filter is working normally, part of the lock catches 350 is placed into the lock grooves 341, and the lock catches 350 latch onto the lock plates 340, thereby locking the cover plate 310 on the upper box body 300. When it is necessary to check the inside of the upper box body 300, the lock catches 350 can be rotated to disengage the lock catches 350 from the lock grooves 341 and separate the cover plate 310 from the upper box body 300.

[0026] Further, the buckle 350 includes a screw 351 and a nut 352. The screw 351 is rotatably connected to the upper box body 300, and the locking groove 341 is located on the rotation path of the screw 351.

[0027] In an embodiment of the present utility model, the nut 352 is screwed onto the screw 351, and the screw 351 is rotatably connected to the upper box body 300. When locking the cover plate 310 onto the upper box body 300, rotate the screw 351 so that a part of the screw 351 is placed into the locking groove 341, and rotate the nut 352 so that the nut 352 tightly presses the buckle 350. Of course, the buckle 350 and the locking plate 340 are in one-to-one correspondence, and multiple sets of buckles 350 and locking plates 340 are provided, and multiple locking plates 340 are fixedly connected to each side of the cover plate 310 respectively, ensuring the reliability of locking the cover plate 310 onto the upper box body 300.

[0028] Further, the nut 352 is an annular nut 352, which is convenient for the operator to rotate the nut 352.

[0029] Further, the upper box body 300 is provided with a stepped surface 360, and multiple fixing seats 361 are arranged on the stepped surface 360. The screw 351 is rotatably connected to the fixing seats 361.
