each annular plate 4 is rotatably arranged in each counter bore on the lower end face of the fixed plate 3, each annular plate 4 is fixedly provided with a vertical rod 7, the lower end of each vertical rod 7 is provided with a horizontal rod, bristles are fixed on the vertical rods 7 and the horizontal rods, the vertical rods 7 and the horizontal rods are arranged on the outer side of the filter cartridge, and the annular plates 4 drive the vertical rods 7 and the horizontal rods to clean the outer side and the lower end of the filter cartridge through the bristles when rotating;

a porous plate 5 is arranged in the shell 1 below the fixed plate 3, a plurality of filter cartridges and vertical rods 7 penetrate through holes in the porous plate 5, and the porous plate 5 can slide up and down in the shell 1;

after the cartridge filter took place to block up, the pressure of 3 lower extreme cavitys of fixed plate can rise, and pressure can push away fixed plate 3 rebound and drive montant 7 and horizontal pole rotation, and pressure disappears the back, and fixed plate 3 resets downwards.

The bottom end of the shell 1 is fixed with a conical shell 2, the small end face of the conical shell 2 is located below the large end face, an air inlet and an ash discharge opening are formed in the conical shell 2, a baffle plate 8 is arranged on the ash discharge opening in the conical shell 2, and the conical shell 2 can be opened and closed through the baffle plate 8.

The annular plate 4 is rotatably arranged in the counter bore through a bearing.

The inside wall of the shell 1 is provided with a chute in the vertical direction, the outer edge surface of the perforated plate 5 is fixed with a slide block, the slide block is slidably mounted in the chute, and the slide block is in contact with the chute through balls.

Perforated plate 5 on every through-hole in all install one can be at the sleeve 6 of through-hole internal rotation, sleeve 6 has a breach, montant 7 is fixed in the breach, sleeve 6's inner flange face, montant 7 and cartridge filter laminating are in the same place, sleeve 6's last lower extreme all has a turn-ups, the turn-ups laminates through the ball with perforated plate 5's upper and lower terminal surface, keeps apart the cavity at both ends about the through-hole on the perforated plate 5.

The breach setting of sleeve 6 on the inner edge face of sleeve 6, the breach runs through upper and lower terminal surface and the outer fringe face of sleeve 6, and does not run through the turn-ups outer fringe face of sleeve 6.

The through-hole inner edge face on the perforated plate 5 on have an internal thread, have the external screw thread with internal thread engaged with on the montant 7, the fixed plate 3 drives montant 7 and horizontal pole through helicitic texture and rotates when removing.

The lower terminal surface of fixed plate 3 on the left and right sides be fixed with many dead levers 9, dead lever 9 passes perforated plate 5, is located the cover on dead lever 9 between fixed plate 3 and the perforated plate 5 and has spring 10, can compress spring 10 after perforated plate 5 upwards removes, spring 10 extension can be with perforated plate 5 resetting down.

The filter cartridge is a cloth bag with support ribs inside, the support ribs can always keep the cloth bag in a cylindrical shape, when the filter cartridge is used, a blower is connected to an air inlet, a baffle 8 on an ash discharge port is closed, the blower is opened, gas with dust is sent into the shell 1, the cloth bag is placed in through holes in the fixed plate 3, the bottom end of the cloth bag penetrates through a sleeve 6 on the porous plate 5 and moves to the position below the porous plate 5, the gas penetrates through the cloth bag below the porous plate 5, the filtered gas passes through an opening at the upper end of the cloth bag and leaves the shell 1 from an air outlet, when the gas penetrates through the cloth bag, the dust in the gas is filtered by the cloth bag, one part of the dust falls into the conical shell 2, and the other part of the dust stays on the outer surface of the cloth bag;

after the cloth bag filters gas for a long time, a large amount of dust is attached to the outer side face of the cloth bag, the gas permeability of the cloth bag is smaller and smaller, the air blower continuously sends gas into the shell 1, the gas pressure below the porous plate 5 is larger and larger, the gas pressure in the shell 1 above the porous plate 5 is kept unchanged, pressure difference is formed between the upper side and the lower side of the porous plate 5, the gas pressure is caused to push the porous plate 5 to move upwards relative to the vertical rod 7 and the fixing rod 9 through the balls and the sliding grooves on the sliding blocks, the porous plate 5 moves upwards while the spring 10 is compressed, the through hole on the porous plate 5 enables the vertical rod 7 and the transverse rod to rotate around the axis of the through hole through threaded matching, meanwhile, the annular plate 4 rotates around the axis of the annular plate per se in the counter bore through the bearing, the vertical rod 7 is positioned in the notch of the sleeve 6, the vertical rod 7 rotates while the sleeve 6 pushes the sleeve 6 to synchronously rotate around the axis of the perforated plate per se through the balls on the turned edge, when the vertical rod 7 and the cross rod rotate, the bristles on the vertical rod 7 and the cross rod clean dust on the outer surface of the cloth bag, so that the air permeability of the cloth bag is gradually increased, the cleaned and fallen dust falls into the conical shell 2, the pressure difference between the upper side and the lower side of the porous plate 5 is gradually reduced, the spring 10 begins to extend, and the porous plate 5 is pushed downwards by the spring 10 to reset;

when the air pressure difference of both sides is not enough to overcome spring 10's elasticity and perforated plate 5's gravity about perforated plate 5, perforated plate 5 then no longer upwards moving, montant 7 and horizontal pole no longer rotate, the brush hair stops to clean the sack surface, when the sack is blockked up by the dust once more, the air pressure difference of both sides forms once more about perforated plate 5, perforated plate 5 will upwards move once more and drive montant 7 and horizontal pole and rotate, make the brush hair clean the sack, when the dust in conical shell 2 piles up too much, open baffle 8 on the row's of ashes mouth, it can to discharge accumulational dust.

The device has the advantages that:

1. the utility model filters gas for a long time through the cloth bag, the dust in the gas causes the air permeability of the cloth bag to be smaller and smaller, so that pressure difference is formed between the upper side and the lower side of the porous plate 5, the porous plate 5 is pushed to move upwards under the action of the gas pressure, so that the vertical rods 7 and the transverse rods rotate, the dust attached to the cloth bag is cleaned by the bristles, the gas filtering efficiency of the cloth bag is ensured, the cloth bag is not required to be cleaned manually or disassembled, when the dust on the cloth bag in the shell 1 increases, the air pressure difference is formed on the upper side and the lower side of the porous plate 5, the porous plate 5 is pushed to move upwards, the brush hair cleans the cloth bag, when the air permeability of the cloth bag returns to normal, the perforated plate 5 can automatically reset downwards under the action of the spring 10, so that the cleaning time is saved while the labor is saved, the dust removal efficiency of the bag-type dust remover is ensured, and the practicability is high.

2. According to the utility model, the rolling balls arranged on the flanging of the sleeve 6 are in contact with the surface of the porous plate 5, and the annular plate 4 is arranged in the counter bore through the bearing, so that the resistance of the porous plate 5 during up-and-down movement can be reduced, and the normal, continuous and stable use of the device can be ensured.
