The upper portion of the filter bag 7 is provided with the iron sheet 7a, and the iron sheet 7a is mutually matched with the electromagnet 209, so that the electromagnet 209 can drive the top of the filter bag 7 to move up and down, dust on the inner wall of the filter bag 7 can be shaken off, and the filter bag 7 can be turned over under the condition that the electromagnet 209 moves downwards all the time.
The upper portion of the first fixing plate 201 is provided with two inclined surfaces so that dust falling on the first fixing plate 201 may slide down from the first fixing plate 201, thereby preventing the falling dust from remaining on the first fixing plate 201.
The upper portion of the through hole 201a of the first fixing plate 201 is provided with a chamfer so that the supporting bar 208 can be guided by the chamfer to more conveniently enter between two adjacent pulleys 202 below the first fixing plate 201.
The dust removing device also comprises a dust removing unit, and each baffle cylinder 9 and each filter cylinder 10 are connected with the dust removing unit together; the ash removing unit comprises a second spring 301, a first conical plate 302, a second conical plate 303 and a storage box 304; a second spring 301 is welded in the baffle cylinder 9; the retaining cylinder 9 is slidably connected with a first conical plate 302, the first conical plate 302 is fixedly connected with the other end of the second spring 301, and dust is collected and dumped through the first conical plate 302; a second conical plate 303 is fixedly connected to the upper portion of the filter cartridge 10.
The mounting plate 5 is in sliding connection with the filter cartridge 10; and the supporting control assembly can drive the filter cartridge 10 to move up and down, so that the ash cleaning unit can move downwards below the air inlet 1a, and the entering air flow can not blow off dust in the dumping process.
The working principle of the embodiment is as follows: since a large amount of dust is adhered to the filter bag 7 during the filtration process of the filter bag 7, after long-time filtration, dust accumulation makes air difficult to pass through the filter bag 7, so that the filtration performance of the filter bag 7 is greatly reduced, then the wind speed of which filter bag 7 is detected by the wind speed detector 116 is too small, so that the condition that the dust of which filter bag 7 is excessively accumulated is judged, then the electromagnet 209 is controlled to be electrified to suck the iron sheet 7a, then the first push rod 11 below the filter bag 7 with excessively accumulated dust is controlled to start, and the filter cartridge 10 is pushed to move upwards, after the filter opening 10a and the rectangular hole 9a are misplaced, the upward movement is stopped, and the state is shown in fig. 6, and the second spring 301 is in a normal state at this time, so that the air cannot enter the filter bag 7 with excessively accumulated dust through the filter opening 10 a.
Taking the view angle of fig. 10 as an explanatory view angle, the motor 204 arranged above is controlled to continuously rotate in the forward and backward directions, i.e. the motor 204 rotates clockwise, then rotates anticlockwise and then rotates clockwise under the view angle of fig. 10, so that the motor 204 continuously switches in the two rotation directions of clockwise and anticlockwise, and the motor 204 simultaneously drives the gear 203 and the pulley 202 arranged above and positioned at the left side, so that the gear 203 and the pulley 202 continuously switch in the two rotation directions of clockwise and anticlockwise, and because the gear 203 arranged above and positioned at the left side is meshed with the other gear 203 arranged above and positioned at the right side, the gear 203 at the right side always rotates in the opposite direction to the gear at the left side, and further, the gear 203 at the right side drives the other pulley 202 connected with the motor to rotate, the end result is that the two pulleys 202 always rotate in opposite directions, at this time, because the bottom of the supporting rod 208 is located between the two pulleys 202 and is in contact with the two pulleys 202, when the left pulley 202 rotates clockwise and the right pulley 202 rotates anticlockwise, the two pulleys drive the supporting rod 208 to move downwards through friction force, and in turn drive the supporting rod 208 to move upwards, the supporting rod 208 and the electromagnet 209 repeatedly move upwards and downwards through the transmission of the pulley 202, the electromagnet 209 sucks the iron sheet 7a, and further the electromagnet 209 can drive the iron sheet 7a and the filter bag 7 to repeatedly bend, deform and reset, and because air cannot enter the filter bag 7 at this time, no airflow exists in the filter bag 7, so that dust stuck in the filter bag 7 is shaken down, then the dust falls on the second conical plate 303 and slides onto the first conical plate 302 from the second conical plate 303, so that the dust accumulated in the filter bag 7 is collected on the first conical plate 302, and because the filter port 10a and the rectangular hole 9a are misplaced, the dust cannot flow out from the filter port 10a, then the motor 204 is controlled to drive the two pulleys 202 to rotate, so that the supporting rod 208 and the electromagnet 209 move downwards, thereby driving the upper part of the filter bag 7 to move downwards, when the electromagnet 209 moves downwards to be attached to the second conical plate 303, the lower end of the supporting rod 208 at the moment is moved between the two adjacent pulleys 202 on the first fixed plate 201, then the motor 204 on the first fixed plate 201 is controlled to start, thereby driving the two adjacent pulleys 202 on the first fixed plate 201, the pulley 202 on the left rotates clockwise, the pulley 202 on the right rotates anticlockwise, and simultaneously the motor 204 on the second fixed plate 207 is controlled to stop rotating, so that the supporting rod 208 and the electromagnet 209 continue to move downwards, and the inner ring of the second conical plate 303 is smaller than the electromagnet 209, so that the electromagnet 209 moves downwards to press the second conical plate 303, and the second conical plate 303, the baffle cylinder 9, the filter cartridge 10 and the first push rod 11 are fixedly connected with each other, so that the second conical plate 303, the filter cartridge 10, the baffle cylinder 9 and all parts connected with the baffle cylinder are moved downwards, the filter cartridge 10 is separated from the vent hole 5a, and the electromagnet 209 is attached to the second conical plate 303 to block, so that air flowing in from the air inlet 1a does not blow dust on the first conical plate 302 through the second conical plate 303, when the second fixing plate 207 moves downwards to be only five to eight centimeters away from the first fixing plate 201, the downward movement is stopped, the first spring 206 is in a compressed state, and then the first push rod 11 is controlled to continuously push the filter cartridge 10 to move upwards, and the filter cartridge 10 is separated from the first conical plate 302, so that the filter cartridge 10 drives the second conical plate 303 to move upwards, and then the second conical plate 303 pushes the supporting rod 208 and the electromagnet 209 to move upwards in the pulley 202, and in the process of moving the electromagnet 209 upwards, the second conical plate 303 is closely attached to the electromagnet 209, so that the second fixing plate 207 is not moved, the first spring 206 is not reset, and is in a state as shown in fig. 9, the second spring 301 is in a normal state, so that dust collected on the first conical plate 302 flows from the first conical plate 302 to the rectangular hole 9a, then slides out of the rectangular hole 9a and then falls into the storage box 304, and then the dust is collected together, thus the dust pouring is completed, and other filter units perform the filtering operation normally at this time, and the air entering through the air inlet 1a cannot influence the dust pouring because the filter cartridge 10 and the baffle 9 are located below the air inlet 1 a.
It should be noted that, since the electromagnet 209 attracts the iron sheet 7a at this time, the electromagnet 209 moves the iron sheet 7a and the upper end of the filter bag 7 between the first fixing plate 201 and the air inlet 1a after moving downward, and since the lower end of the filter bag 7 is fixed to the slider 6, the filter bag 7 is turned over after the iron sheet 7a and the upper end of the filter bag 7 move downward, and the first spring 206 is in a compressed state as shown in fig. 11, so that the inner wall of the filter bag 7 is exposed to the lower case 1, and thus, some dust remaining on the inner wall of the filter bag 7 is blown away under the impact of the air flowing in from the air inlet 1a, so that the dust adhering to the filter bag 7 is greatly reduced, and cleaning of the filter bag 7 is completed.
Then, the motor 204 on the first fixing plate 201 is controlled to drive the supporting rod 208 and the electromagnet 209 to move upwards for resetting, so that the first spring 206 resets and pushes the second fixing plate 207, the baffle cylinder 9, the filter cartridge 10 and all parts connected with the filter cartridge to move upwards, the second conical plate 303 is still tightly attached to the electromagnet 209 in the process of upward movement of the electromagnet 209, after resetting, the filter cartridge 10 is attached to the mounting plate 5 again, then the first push rod 11 is controlled to push the filter cartridge 10 to move downwards, so that the filter port 10a and the rectangular hole 9a are aligned, the state shown in fig. 5 is achieved, the second spring 301 is in a compressed state at the moment, air flowing into the air inlet 1a enters the filter bag 7 again, and then the electromagnet 209 and the iron sheet 7a are separated under the blowing of air flow, so that the filter bag 7 is overturned back again, and resetting is completed.
