It should be noted here that the pore size of the filter plate 4 becomes smaller from the direction of the dust collecting port 3. After the exhaust mechanism is started for a period of time, the exhaust mechanism is stopped, and most of the dust remaining on the filter plate 4 will fall into the ash discharge box 2 through the dust outlet 6 provided at the bottom of the filter box 1. At this time, some dust on the filter plate 4 will still be stuck to the filter plate 4 and will not fall off;

A knocking ball 19 is provided at the other end of the knocking rod 18, and the knocking ball 19 contacts the two filter plates 4 close to it. Specifically, by starting the electric telescopic rod 15, it drives the support rod 16, the two lifting rods 17, and the knocking rod 18 to produce a certain displacement in the vertical direction and then stop. By forward and reverse rotation of the first motor 9, the first motor 9 drives the rotating rod 10 to rotate, and at the same time drives the first sliding sleeve 12, the second sliding sleeve 13, the support rod 16, the two lifting rods 17, and the knocking rod 18 to reciprocate in the horizontal direction, and finally realizes that the knocking ball 19 provided at the end of the knocking rod 18 intermittently contacts the two filter plates 4 close to it, knocks the dust that has not fallen on the filter plate 4, makes it fall into the ash discharge box 2, and finally discharges the ash through the ash discharge mechanism provided in the inner cavity of the ash discharge box 2.
[0026] Furthermore, the exhaust mechanism includes an exhaust fan 20 fixed to the outside of the filter box 1, the exhaust fan 20 is connected to an exhaust pipe 21, and the exhaust pipe 21 extends through the side wall of the filter box 1 to the inner cavity of the filter chamber 5.

[0027] Furthermore, the ash discharge mechanism includes a plurality of ash discharge hoppers 22 connected with a plurality of filter chambers 5, the bottom of the ash discharge hopper 22 is connected with an ash discharge pipe 23, the other end of the ash discharge pipe 23 passes through the bottom of the ash discharge box 2 and extends to the outside of the ash discharge box 2, and the inner cavity of the ash discharge hopper 22 is provided with an ash discharge component, and the ash discharge component includes two fixed blocks 24 symmetrically fixed to the inner cavity side wall of the ash discharge hopper 22, and the other end of the fixed block 24 is hinged with a cross plate 25, and a gravity sensor 26 is installed on the top of the cross plate 25. A supporting component is provided below the cross plate 25, and the supporting component is in contact with the bottom of the cross plate 25. The supporting component includes a second motor 27 fixed to the inner cavity of the ash discharge hopper 22, and the output end of the second motor 27 is connected to a cam Block 28, the protrusion 28 is in contact with the bottom of the horizontal plate 25. Specifically, when dust discharge is not performed, the second motor 27 and the protrusion 28 are in a static state. In the static state, the protrusion 28 makes the two horizontal plates 25 in a horizontal state. When the dust falling on the horizontal plate 25 reaches a certain weight, the second motor 27 will start, driving the protrusion 28 to rotate a certain angle. At this time, one end of the horizontal plate 25 hinged to the fixed block 24 tilts downward, and the dust on the horizontal plate 25 is discharged through the ash discharge pipe 23 connected to the bottom of the ash discharge hopper 22, and automatic ash discharge is achieved through the gravity sensor 26. It should be noted here that the gravity sensor 26 and the second motor 27 are connected through a controller.
[0028] Furthermore, two guide slopes 29 are symmetrically fixed to the inner cavity of the ash hopper 22 above the fixed block 24. Specifically, by setting the guide slopes 29, the dust falling from the dust outlet 6 falls along the two guide slopes 29 to the inner cavity of the ash hopper 22, making the flow of dust smoother.
[0029] It can be seen from the above technical solution that when in use, the exhaust fan 20 is started, and the dust-carrying gas is passed from the dust collecting port 3 into the inner cavity of the filter box 1, and is filtered through the multiple filter plates 4 arranged in the inner cavity of the filter box 1 in sequence, and the filtered dust will remain on the filter plate 4. It should be noted here that the aperture size of the filter plate 4 gradually decreases from the direction of the dust collecting port 3. After the exhaust fan 20 is started for a period of time, the exhaust fan 20 is stopped, and most of the dust remaining on the filter plate 4 will fall into the ash discharge box 2 through the dust outlet 6 opened at the bottom of the filter box 1. At this time, some dust on the filter plate 4 will still be stuck to the filter plate 4, by starting the electric telescopic rod 15, it drives the support rod 16, the two lifting rods 17, and the knocking rod 18 to produce a certain displacement in the vertical direction and then stop, by forward and reverse rotation of the first motor 9, the first motor 9 drives the rotating rod 10 to rotate, and at the same time drives the first sliding sleeve 12, the second sliding sleeve 13, the support rod 16, the two lifting rods 17, and the knocking rod 18 to reciprocate in the horizontal direction, and finally realizes that the knocking ball 19 set at the end of the knocking rod 18 intermittently contacts the two filter plates 4 close to it, knocks the dust that has not fallen on the filter plate 4, and makes it fall into the ash discharge box 2;
[0030] Finally, the ash is discharged through the ash discharge mechanism set in the inner cavity of the ash discharge box 2. Specifically, when the ash is not discharged, the second motor 27 and the protrusion 28 are in a static state. In the static state, the protrusion 28 makes the two cross plates 25 in a horizontal state. When the dust falling on the cross plate 25 reaches a certain weight, the second motor 27 will start, driving the protrusion 28 to rotate a certain angle. At this time, one end of the cross plate 25 hinged to the fixed block 24 tilts downward, and the dust on the cross plate 25 is discharged through the ash discharge pipe 23 connected to the bottom of the ash discharge hopper 22. Automatic ash discharge is achieved through the gravity sensor 26. It should be noted here that the gravity sensor 26 and the second motor 27 They are connected through a controller, and a guide slope 29 is set in the inner cavity of the ash hopper 22, so that the dust falling from the dust outlet 6 can fall along the two guide slopes 29 to the inner cavity of the ash hopper 22, so that the flow of dust is smoother, which solves the problem that more dust will be generated in the cement production and processing process. Under normal circumstances, after a period of dust removal, a lot of dust will accumulate inside the dust bag of the bag dust collector used, which will block the dust bag, and the actual cleaning effect is not good, thereby affecting the dust removal efficiency in the later stage. In addition, the ash removal method generally adopts continuous ash removal or manual ash removal, and manual ash removal will have the problem of excessive ash due to untimely ash removal, thus affecting the dust removal effect.
