[0050] The dust removal filter element 11 is mounted on the fixed plate;

[0051] The sound-absorbing panel 12 is disposed at the air inlet 102; the sound-insulating panel 13 is disposed on the outer surface of the sound-absorbing panel 12; preferably, the sound-absorbing panel 12 is a glass wool sound-absorbing panel 12. Preferably, the sound-insulating panel 13 is a sound-insulating felt. By absorbing noise at the air inlet 102, the sound-insulating panel 13 isolates noise, preventing the dust collector from generating excessive noise during dust removal. Both the sound-absorbing panel 12 and the sound-insulating panel 13 have clearance holes (not shown in the figure) corresponding to the air inlet 102.

[0052] The pulse device 14 includes an air storage tank 141, a plurality of pulse valves 142 and a plurality of blow pipes 143.

[0053] The dust collection box 15 is provided at the corresponding ash leakage port; the dust collection box 15 is provided with a handle, and a locking ring is connected to the handle. Correspondingly, the dust collector body 10 is provided with a locking part at the corresponding handle. The handle is locked to the locking part by the locking ring, so that the dust collection box 15 is detachably locked to the lower end of the dust collector body 10.

[0054] The grayscale sensor 16 is disposed on the dust collector filter element 11; preferably, the grayscale sensor 16 is connected to the control unit 20 through an analog-to-digital converter 19. The grayscale sensor 16 detects the grayscale signal in the filter element and transmits the signal to the control unit 20, which controls the start and end of the dust cleaning process by controlling the opening and closing of the pulse valve 142.

[0055] A grayscale sensor 16 is used to detect dust inside the dust collector filter element 11. When dust accumulates in the filter element 11, the intensity of the reflected light changes after illumination, resulting in a change in grayscale value, thus achieving dust detection. The grayscale sensor 16 is an analog sensor, consisting of a light-emitting diode (LED) and a photoresistor mounted on the same surface. The grayscale sensor 16 utilizes the principle that different colored detection surfaces reflect light differently, and the photoresistor exhibits different resistance values ​​to light reflected from different detection surfaces to detect color depth. Within the effective detection distance, the LED emits white light, illuminating the detection surface. The detection surface reflects some of the light, and the photoresistor detects the intensity of this light and converts it into an analog signal. Because the grayscale sensor 16 outputs an analog signal, it needs to be converted into a digital signal that can be processed by a processor. An analog-to-digital converter 19 (A / D converter) converts the analog signal from the grayscale sensor 16 into a digital signal that the processor can process, enabling control via the processor.

[0056] The ash volume sensor 17 is disposed on the dust collection box 15; preferably, the ash volume sensor 17 is a pressure sensor. The buzzer 18 is disposed on the dust collector body 10; in this embodiment, the pressure sensor compares the pressure value with a preset pressure value. When the pressure value in the dust collection box 15 exceeds the preset pressure value, the pressure sensor sends the pressure value to the control unit 20, and the control unit 20 controls the buzzer 18 to sound to prompt manual replacement; the pressure sensor can be electrically connected to the control unit 20 in various ways, such as by digital signal connection or wireless connection. These connection methods are well known in the art and will not be described in detail here.

[0057] The control unit 20 is electrically connected to the pulse valve 142, the grayscale sensor 16, the gray volume sensor 17, and the buzzer 18. A corresponding control program is typically embedded within the control unit 20, which can be an industrial-grade microcontroller.

[0058] Preferably, a temperature sensor 30 is also provided in the dust removal space 101, and the temperature sensor 30 is electrically connected to the control unit 20. Preferably, an automatic fire extinguishing device 40 is also provided on the dust collector body 10, the automatic fire extinguishing device 40 includes an electric valve 41 and a fire extinguishing canister 42, the electric valve 41 is installed at the canister opening of the fire extinguishing canister 42 and the electric valve 41 can control the opening or closing of the canister opening of the fire extinguishing canister 42; the output end of the fire extinguishing canister 42 is connected to the dust removal space 101; the electric valve 41 is electrically connected to the control unit 20. In this embodiment, during industrial cutting activities, excessively hot residue and dust are generated, along with some flammable materials. When these high-temperature residues, dust, and flammable materials are directly absorbed by the dust collector, they can easily ignite inside the dust collector and cause an explosion. Utilizing the design of the temperature sensor 30 and the automatic fire extinguishing device 40, the temperature sensor 30 continuously monitors the temperature inside the dust collector body 10. When the temperature inside the dust collector body 10 exceeds the preset value of the temperature sensor 30, the temperature sensor 30 transmits the sensed temperature signal to the control unit 20. The control unit 20 then controls the automatic fire extinguishing device 40 to automatically spray fire extinguishing material into the dust collector body 10, thereby extinguishing the fire.

[0059] Preferably, the dust collector body 10 is further provided with a fan assembly, which includes a fan and a drive device for driving the fan to rotate. The fan is disposed within the dust collector body 10 and communicates with the dust collection chamber. The drive device is disposed within the dust collector body 10 and electrically connected to the control unit 20. The fan assembly is a well-known technology in the field and will not be described in detail here.

[0060] The key design feature of this utility model is that it mainly uses a grayscale sensor to detect the dust content in the filter element. The dust content detected by the grayscale sensor is compared with a set value. After the deviation is obtained, an output signal is generated according to a certain adjustment rule to control the pulse valve to work and eliminate the deviation, so that the dust content in the filter element is kept near the set value, thus ensuring the effectiveness of the dust removal control.

[0061] Secondly, the design of the ash volume sensor and buzzer ensures that when the dust in the dust collection box accumulates to a certain amount, it will trigger the preset value of the pressure sensor, thereby causing the control unit to control the buzzer to sound, thus prompting the staff to clean the dust, avoiding the accumulation of dust in the dust collection box and preventing the backflow of dust in the dust collection box.

[0062] Next is the design of the sound-absorbing panel and the sound-insulating panel.
