The area of the electronic scale 5 is smaller than that of the plate valve core 2, ensuring that the plate valve core 2 can rotate in and out of the dust discharge pipe opening 1 normally, realizing the opening and closing operations of the dust discharge pipe opening 1. The pulse dust collector starts the electromagnetic pulse valve, and the powerful impact force generated by the instant release of high-pressure gas quickly removes the dust deposited on the surface of the filter bag. The dust falls into the hopper and accumulates on the electronic scale 5. When the weighing weight reaches the set value, the PLC controller 6 receives the signal, makes the servo motor 4 energize and start, and the plate valve core 2 rotates 90 degrees to open the dust discharge pipe opening 1. The dust enters the dust cleaning mechanism 7, and the dust cleaning mechanism 7 can push and clean the accumulated dust to avoid the accumulation of dust at the bottom of the dust discharge pipe opening 1, resulting in a dirty and messy surrounding environment.

[0020] As a technical optimization scheme of the present utility model, the dust cleaning mechanism 7 includes a conveyor cylinder 9, a screw conveyor 10, and a driving motor 11; the screw conveyor 10 is located inside the conveyor cylinder 9, the motor is arranged on the conveyor cylinder 9, one end of the screw conveyor 10 is fixedly arranged at the output end of the driving motor 11, the conveyor cylinder 9 is provided with an ash inlet 12 and an ash outlet 13, the ash inlet 12 is arranged at the bottom of the dust discharge pipe opening 1 through a flange, and the driving motor 11 is electrically connected to the PLC controller 6.

[0021] In this embodiment: when the dust discharge port 1 is opened, the PLC controller 6 controls the driving motor 11 to be powered on, and the auger 10 rotates to push and clean the accumulated dust, avoiding the accumulation of dust at the bottom of the dust discharge port 1 and causing the working environment to be dirty and messy.

[0022] As a technical optimization scheme of the present utility model, the collection mechanism 8 includes a dust-proof chamber 14 and an ash storage cart 15 arranged in the dust-proof chamber 14. A sealing plate 16 is arranged on one side of the ash storage cart 15 away from the dust-proof chamber 14. A push rod is arranged on the sealing plate 16, and the bottom of the ash outlet 13 is communicated with the bottom of the dust-proof chamber 14.

[0023] In this embodiment: the ash storage cart 15 is located below the ash outlet 13, and the accumulated dust can be directly collected into the ash storage cart 15. The sealing plate 16 is attached to the inlet end of the dust-proof chamber 14 to reduce the dust from drifting outside the dust-proof chamber 14.

[0024] As a technical optimization scheme of the present utility model, a threaded seat 17 is arranged at the top end inside the dust-proof chamber 14. A screw rod 18 with a handle at one end is arranged on the sealing plate 16, and the other end of the screw rod 18 is threadedly inserted into the threaded seat 17.

Both the distance sensor 19 and the alarm 20 are electrically connected to the PLC controller 6.

[0027] In this embodiment: the distance sensor 19 monitors the accumulated dust inside the ash storage cart 15 in real time. When the height of the accumulated dust in the ash storage cart 15 reaches the set value, the PLC controller 6 powers on the alarm 20, and the alarm 20 gives an alarm to remind the operator to clean the ash.

[0028] Working principle: First, the pulse dust collector starts the electromagnetic pulse valve to clean the dust deposited on the surface of the filter bag. The dust falls into the ash hopper and accumulates on the electronic scale 5. When the electronic scale 5 weighs and the weighed weight reaches the set value, the PLC controller 6 receives the signal, energizes and starts the servo motor 4, rotates the plate valve core 2 by 90 degrees, opens the dust discharge pipe orifice 1, and the dust enters the dust cleaning mechanism 7. The PLC controller 6 controls the drive motor 11 to be energized, and the auger 10 rotates to push the accumulated ash, preventing the accumulated ash from piling up at the bottom of the dust discharge pipe orifice 1 and causing the surrounding environment to be dirty and messy. The accumulated ash is pushed into the dust-proof cavity 14 through the ash outlet 13. The ash collecting vehicle 15 can directly collect the accumulated ash. The sealing plate 16 is attached to the vehicle inlet end of the dust-proof cavity 14 to reduce the dust from drifting outside the dust-proof cavity 14. When the value monitored by the distance sensor 19 reaches the set value, the PLC controller 6 energizes the alarm 20, and the alarm 20 gives an alarm to remind the operator to clean the ash.
