[0058] Among them, the treatment tank 82 is fixedly connected to the supporting rod 81, and an upper space 821 and a lower space 822 are reserved in the treatment tank 82 from top to bottom.

The upper ends of the stripping channels 83 pass through the upper space 821 and extend to the top of the treatment tank 82 .

[0060] A plurality of through grooves 831 connected to the upper space 821 are reserved on the stripping channel 83 at the micro-holes on the stripping channel 83. The lower end of the stripping channel 83 passes through the lower space 822 and is threadedly connected to a closing block 832. The stripping channel 83 is used to strip impurities in the drawn-in polluted gas in the lower space 822. The diameter of the impurities in the polluted gas is larger than the diameter of the micro-holes on the stripping channel 83.

[0061] The traction unit 84 is installed at the upper end of the treatment tank 82, and a plurality of debris stripping units 85 are installed in the corresponding stripping channels 83. Each debris stripping unit 85 includes a carrying unit 851 and a decontamination unit 852.

The number of the debris stripping units 85 is equal to the number of the stripping channels 83.

[0062] A cavity for collecting debris is reserved between the carrying unit 851 and the closing block 832.

[0063] The decontamination unit 852 is movably installed in the stripping channel 83. The upper end of the decontamination unit 852 passes through the stripping channel 83 and is connected to the traction unit 1 84. Among them, the traction unit 1 84 is used to pull the decontamination unit 852 to perform vertical movement to remove debris adhering to the inner wall of the stripping channel 83.

[0065] When the contaminated gas during cutting is treated, the purification module 8 draws the contaminated gas into the inlet channel 823, the contaminated gas flows into the upper space 821 through the inlet channel 823, and flows into the stripping channel 83 through the through groove 831 on the stripping channel 83, the contaminated gas in the stripping channel 83 flows into the lower space 822 through the micro-holes on the stripping channel 83, and flows away from the lower space 822 by the outflow channel 824.

[0066] When the stripping channel 83 has been used for a long time, the impurities in the polluted gas are stripped out by the stripping channel 83. Since the stripped out impurities adhere to the inner wall of the stripping channel 83, in order to prevent the adhered impurities from weakening the stripping function and speed of the stripping channel 83, the user can control the traction unit 2 86 to pull a number of stripping channels 83 to rotate, and control the traction unit 1 84 to pull the decontamination unit 852 to perform vertical movement, and remove the impurities adhered to the inner wall of the stripping channel 83, and the removed impurities fall into the sealing block 1 832 under their own weight.

[0067] After the debris in the closing block 832 has accumulated to a certain amount, the user can manipulate the traction unit 84 to pull the decontamination unit 852 downward, allowing the decontamination unit 852 and the supporting unit 851 to cooperate with each other and seal the lower end of the stripping channel 83. It should be clarified that the lower end of the stripping channel 83 here refers to the lower end of the stripping channel 83 at the upper end of the closing block 832, not the lowest end of the stripping channel 83.

[0068] Next, the user opens the lower end of the stripping channel 83 by rotating the sealing block 832, and then takes out the removed debris from the stripping channel 83. This method can perform decontamination during the operation of the device, and then ensure the continuous high-speed operation of the stripping effect on the debris in the polluted gas, which can not only greatly speed up the treatment speed, but also extend the normal working time of the stripping channel 83 and reduce the cost of maintenance.

[0069] Reference Figure 7 and Figure 8 The traction unit 84 includes a bearing seat 841 , a bearing sheet 842 and a linear push rod 843 .

[0070] Among them, the bearing seat 841 is fixedly connected to the upper wall surface of the treatment tank 82, and the bearing sheet 842 is vertically slidably installed on the bearing seat 841.

[0071] The linear push rod 843 is installed on the upper end of the bearing seat 841 , and the movable end of the linear push rod 843 is fixedly connected to the upper wall surface of the bearing sheet 842 .

[0072] The user can manipulate the linear push rod 843 to pull the carrier plate 842 to pull the decontamination unit 852 to perform vertical movement.

[0073] Reference Fig.10 and Fig.12 The carrying unit 851 includes a carrying platform 8511 , a support 8512 and a rotating rod 8513 .

[0074] Among them, the supporting platform 8511 is screwed on the stripping channel 83 and is located on the closing block 832. The supporting platform 8511 is provided with a discharge groove 8501.

[0075] The support 8512 is fixedly connected to the lower wall surface of the supporting platform 8511, and the rotating rod 8513 is vertically fixedly connected to the support 8512. A stop wedge is installed on the outer peripheral wall of the rotating rod 8513. The upper end of the rotating rod 8513 passes through the discharge groove 8501 and extends into the upper space 821.

[0076] Reference Figure 10-12 The decontamination unit 852 includes an outer tube 8521 and a decontamination sheet 8522, wherein one end of the outer tube 8521 is fixedly connected to the supporting sheet 842, and a second anti-rotation wedge is installed on the outer peripheral wall of the outer tube 8521. The other end of the outer tube 8521 extends into the stripping channel 83 and is clamped on the rotating rod 8513. During the vertical movement, the outer tube 8521 is always clamped on the rotating rod 8513 to prevent the stripping channel 83 from rotating and pulling the supporting platform 8511 to rotate, thereby allowing the decontamination sheet 8522 and the discharge groove 8501 to always correspond to each other.

[0077] The cleaning piece 8522 is connected to the lower end of the outer tube 8521 by a hoop, and the cleaning piece 8522 and the discharge groove 8501 are adapted to each other, wherein the cleaning piece 8522 is used to remove the sundries adhering to the inner wall surface of the stripping channel 83, and the cleaning piece 8522 can also be used to control the opening and closing of the discharge groove 8501. The head of the cleaning piece 8522 contacts the inner wall surface of the stripping channel 83.

[0078] The specifications of the discharge groove 8501 are consistent with those of the decontamination sheet 8522, and the decontamination sheet 8522 and the discharge groove 8501 are adapted to each other.

[0079] The traction unit 2 86 includes a motor 861 and a linkage unit 862, wherein the motor 861 is installed on the side wall of the treatment tank 82, and the rotating part of the motor 861 is connected to the upper ends of the respective stripping channels 83 through the linkage unit 862, wherein the motor 861 is used to pull the linkage unit 862 to pull the plurality of stripping channels 83 to perform rotation.

[0080] The linkage unit 862 includes a plurality of linkage parts, and the number of the plurality of linkage parts corresponds to the number of the stripping channels 83. Each linkage part includes a pair of sprockets and a chain, and the pair of sprockets are respectively hooped and fixedly connected to a pair of supporting tubes fixedly connected to the upper ends of the adjacent stripping channels 83, and the chains are respectively hooped and fixedly connected to the pair of sprockets and meshed with each other. The plurality of stripping channels 83 are sequentially linked and connected to each other through the plurality of linkage parts, and are connected to the rotating part of the motor 861.

[0081] The linkage unit 862 is controlled by the action of the motor 861 to pull the plurality of stripping channels 83 to rotate together.

[0082] After the stripping channel 83 performs stripping of impurities in the polluted gas for a long time, most of the solid impurities in the polluted gas are retained in the stripping channel 83. Since the stripped solid impurities are easily adhered to the inner wall surface of the stripping channel 83, in order to prevent the adhered solid impurities from weakening the stripping function and speed of the stripping channel 83, the motor 861 can be controlled to pull the linkage unit 862 to pull a plurality of stripping channels 83 to rotate together, and the linear push rod 843 can be controlled to pull the carrier sheet 842 to perform vertical movement. The vertically moving carrier sheet 842 pulls the decontamination sheet 1 8522 to perform vertical movement through the outer tube 8521. With the rotation of the stripping channel 83, the decontamination sheet 1 8522 removes the solid impurities adhered to the inner wall surface of the stripping channel 83. The removed solid impurities fall into the closed block 1 832 through the discharge groove 8501 on the carrier 8511 under their own weight, that is, fall into the cavity between the carrier 8511 and the closed block 1 832.

[0083] When a certain amount of solid impurities accumulate in the sealing block 832, the moving end of the linear push rod 843 is extended and pulled to move the cleaning sheet 8522 downward, so that the cleaning sheet 8522 extends into the discharge groove 8501 and seals the discharge groove 8501, thereby blocking the cleaned solid impurities and the micro-holes on the stripping channel 83.

[0084] Then, the lower end of the stripping channel 83 is opened by rotating the closing block 832, and the cleaned solid impurities are released from the stripping channel 83. Then, during the period when the stripping channel 83 treats the polluted gas, the removed solid impurities can be cleaned out of the stripping channel 83. This method can also perform decontamination during the operation of the device, thereby ensuring the continuous and efficient operation of the polluted gas during the stripping period, which not only greatly improves the work efficiency and reduces the production loss caused by shutdown and cleaning, but also effectively prolongs the service life of the stripping channel 83 and reduces the maintenance cost.

[0085] In order to facilitate the automatic control of the motor 861 and the linear push rod 843 on time, the electric control cabinet 9 is electrically connected to the motor 861 and the linear push rod 843. The decontamination cycle can be set in advance through the electric control cabinet 9, and when decontamination needs to be performed, the electric control cabinet 9 can automatically control the motor 861 and the linear push rod 843 to perform the work.

[0086] Reference Fig.13 and Fig.14 The clean air module 8 also includes a plurality of debris stripping units 87 and a discharge unit 88 .

[0087] Among them, a plurality of debris stripping units 87 are respectively connected to the corresponding stripping channels 83, and the debris stripping units 87 are fixedly connected to the treatment tank 82. Among them, the debris stripping units 87 are used to remove solid impurities adhering to the outer wall of the stripping channel 83, and the discharge unit 88 is installed at the lower end of the treatment tank 82. The number of the plurality of debris stripping units 87 is equal to the number of the stripping channels 83.

[0088] Reference Fig.14 The debris stripping unit 87 includes a pair of circular sleeves 871 and a plurality of decontamination sheets 872 .

[0089] A pair of circular sleeves 871 are respectively connected to the stripping channel 83, one of the circular sleeves 871 is fixedly connected to the upper wall of the lower space 822, and the other circular sleeve 871 is fixedly connected to the lower wall of the lower space 822. A plurality of decontamination sheets 872 are arranged in a ring between the pair of circular sleeves 871, and the decontamination sheets 872 are in contact with the outer peripheral surface of the stripping channel 83.

[0090] Reference Fig.13 The discharge unit 88 includes a discharge channel 881, a switch 882 and a closing block 883, wherein the discharge channel 881 is connected to the lower end of the treatment tank 82 through the switch 882, and the closing block 883 and the discharge channel 881 are threadedly connected.

[0091] At the beginning, the switch 882 is in the open state. In order to facilitate the removal of the solid impurities removed from the outer wall of the stripping channel 83 from the treatment tank 82, the lower end of the treatment tank 82 can be arranged in a conical shape.

[0092] Reference Fig.15The clean air module 8 also includes an absorption unit 89, which includes a box body 891. A discharge pipe 892 is installed inside the box body 891. The box body 891 is filled with absorbent. One end of the discharge pipe 892 is connected to the outflow channel 824, and the other end of the discharge pipe 892 is in the absorbent. There are several exhaust holes 893 on the discharge pipe 892 in the absorbent. The side of the box body 891 is connected to a connecting pipe four 894. The connecting pipe four 894 is above the liquid level of the absorbent. The other end of the connecting pipe four 894 is connected to the other end of the fan 713. The gas after stripping flows to the discharge pipe 892 through the outflow channel 824. The discharge pipe 892 sprays the gas evenly into the absorbent in the box body 891. The absorbent treats the gas. The treated gas floats out of the absorbent and then flows away through the connecting pipe four 894.

[0093] When the contaminated gas moves from the stripping channel 83 to the outside of the stripping channel 83, the solid impurities in the contaminated gas will adhere to the outer wall of the stripping channel 83. In order to prevent the solid impurities adhered to the outer wall of the stripping channel 83 from weakening the ventilation function of the stripping channel 83, the installed decontamination sheet 872 is in contact with the outer wall of the stripping channel 83. That is, when the stripping channel 83 rotates, the decontamination sheet 872 can remove the solid impurities adhered to the outer wall of the stripping channel 83. The removed solid impurities fall into the lower space 822 under their own weight, and fall into the closing block 883 through the switch 882.

[0094] When the dust particles in the sealing block 883 accumulate to a certain extent, the switch 882 is closed to block the solid impurities that fall into the sealing block 883 and the lower space 822. Then, the sealing block 883 is rotated to open the discharge port of the discharge channel 881, and the solid impurities removed from the outer wall of the stripping channel 83 are discharged from the treatment tank 82.

[0095] When a certain amount of solid impurities accumulate on the stripping channel 83, they can be decontaminated during the operation of the device, thereby ensuring continuous high-speed stripping of impurities in the polluted gas. This can not only greatly speed up the treatment process, but also extend the normal working time of the stripping channel 83 and reduce the cost of maintenance.
