The upper end of the output shaft of the scraper motor 92 passes through the bottom of the dust collecting chamber 2, and the scraper member 91 is installed on its upper end. The scraper member 91 can move the dust away from the dust outlet 14 to the dust outlet 14; an air-tight unloading mechanism is provided at the bottom of the dust collecting chamber 2, and the position of the air-tight unloading mechanism corresponds to the position of the dust outlet 14, and the air-tight unloading structure is used to process the collected dust; a wind pressure sensor 11 is provided in the dust collecting chamber 2, and the wind pressure sensor 11 is used to measure the condition in the dust collecting chamber 2 to determine whether the filter bag 6 needs to be cleaned; the specification of the wind pressure sensor 11 is 1000-5000Pa, and its model is DPS5000A, and the alarm pressure can be set; the wind pressure sensor 11 is connected to an external PLC controller, and the model of the PLC controller is Siemens PLC st20, and the vibration component 7 and the scraper motor 92 are both connected to the PLC controller, and the PLC controller controls each component.

[0035] like Fig.10 As shown, the air-tight unloading mechanism includes a first shell 101, a sealing plug plate 102 and a dust bag 103. The bottom surface of the dust collecting chamber 2 is provided with a first shell 101 with an opening at one end. The first shell 101 is communicated with the interior of the dust collecting chamber 2. The position of the first shell 101 corresponds to the position of the dust outlet 14, so that dust enters the dust bag 103 through the dust outlet 14 and the first shell 101; a sealing plug plate 102 for blocking the dust outlet 14 is provided inside the open end of the first shell 101, and the sealing plug plate 102 is slidably matched with the first shell 101 to seal the dust outlet 14. The dust bag 103 communicated with the interior of the first shell 101 is installed on the bottom surface of the first shell 101.

[0036] like Fig. 9As shown, the scraper 91 includes a cone 911 and a scraper 912. The upper end of the output shaft of the scraper motor 92 is connected to the bottom surface of the cone 911. The scraper motor 92 drives the cone 911 to move. An L-shaped scraper 912 is provided on the side of the cone 911. The opening direction of the recess of the scraper 912 is opposite to the movement direction, ensuring that the long end of the scraper 912 in the vertical direction contacts the dust and moves the dust.

[0037] like Figure 5 and Fig.10 As shown, the bottom surface of the dust collecting chamber 2 is provided with an inspection port 121, which is convenient for workers to enter for repair; a cover 122 is provided inside the inspection port 121, which prevents gas from leaking from the inspection port 121; a rotating baffle 123 is installed on the bottom surface of the dust collecting chamber 2 through a cylinder, and the top surface of the rotating baffle 123 contacts the bottom surface of the cover 122, and the rotating baffle 123 can fix the cover 122 in the inspection port 121. The front of the clean air chamber 1 is also provided with an observation inspection port for observing the condition of the filter bag 6.

[0038] like Figure 1 and Figure 2 As shown, the bracket of the dust collecting chamber 2 is provided with two groups of symmetrically distributed reinforcing rods 13, one group is inclined, and the other group is a cross structure. The reinforcing rods 13 are simple in structure, easy to process, and are conducive to improving the overall stability of the structure.

[0039] During operation, dust-laden gas enters the dust collecting chamber 2 through the air inlet 3, enters the interior of the filter bag 6 at a relatively low wind speed in the dust collecting chamber 2, and is discharged through the air outlet 5 of the cover plate 4 after being filtered by the filter bag 6; when dust accumulates to a certain thickness on the inner wall of the filter bag 6, the wind pressure sensor 11 detects that the pressure in the dust collecting chamber 2 becomes larger, and transmits a signal to the PLC controller, and the PLC controller determines that there is a lot of dust adhering to the inner wall of the filter bag 6, and the filter bag 6 needs to be cleaned in time; the PLC controller sends a command to the vibration motor 76, and the vibration motor 76 starts to drive the filter bag 6 to vibrate, and the dust is shaken off to the bottom of the dust collecting chamber 2; during the cleaning process, The wind pressure sensor 11 works continuously, and when it measures that the pressure in the dust collecting chamber 2 tends to the pressure at which the gas passes normally, it sends a signal to the PLC controller again, causing the vibration motor 76 to stop working; then, the PLC controller starts the scraper motor 92, and the scraper motor 92 drives the cone 911 to rotate. The cone 911 causes the dust falling from the filter bag 6 to move to a position away from the center of the dust collecting chamber 2 to prevent the scraper 91 from not cleaning in place. The rotation of the cone 911 drives the scraper 91 to move the dust away from the dust outlet 14 to the dust outlet 14 for processing, so as to avoid excessive dust accumulation in the dust collecting chamber 2 affecting the use.

[0040] When the dust in the dust bag 103 is full, the worker moves the sealing plug plate 102 along the inner wall of the first shell 101 toward the center of the dust chamber 2, and the top surface of the sealing plug plate 102 contacts the bottom surface of the dust outlet 14, thereby blocking the dust outlet 14 to prevent the gas in the dust chamber 2 from leaking from here; then remove the dust bag 103, install a new dust bag 103 on the first shell 101, and then move the sealing plug plate 102 outward along the inner wall of the first shell 101, so that the dust chamber 2, the first shell 101, and the dust bag 103 are connected, and the dust that falls continues to be collected. During the entire replacement process, there is no need to stop work, ensuring that the gas is always filtered without affecting work efficiency.
