[0023] Please refer to Figure 1 and Figure 2 The exhaust gas treatment device 100 of this embodiment is used to treat the exhaust gas and remove impurities in the exhaust gas, and includes an equipment body 10 and a filter component 20.

[0024] A processing chamber 16 is provided in the device body 10. Specifically, in the present embodiment, the device body 10 is cylindrical, and the cavity inside it is the processing chamber 16, which is used to pass the waste gas into the processing chamber 16 for treatment. Furthermore, an air inlet 14 and an air outlet 15 are provided at both ends of the device body 10. Specifically, the air inlet 14 is located on the top surface of the device body 10, and the waste gas is introduced through the air inlet pipe 141. The air outlet 15 is located at the bottom of the side wall of the device body 10, and the waste gas is discharged through the air outlet pipe 152.

[0025] Optionally, in other embodiments, the device body 10 can be configured in other shapes, such as a square tube or a multi-prism tube, as long as the internal processing chamber 16 can be formed, the utility model does not limit this. In other embodiments, the air inlet 14 can be arranged on the top side wall of the device body 10, and the air outlet 15 can also be arranged on the bottom wall of the device body 10, as long as the air inlet 14 and the air outlet 15 are located at both ends of the processing chamber 16, the utility model does not limit this.

[0026] Specifically, the gas outlet 15 is provided with a valve 151. In the present embodiment, the valve 151 is a solenoid valve, which is used to open or close the gas outlet 15, and the switch of the solenoid valve is controlled by the controller, thereby controlling the treated waste gas to be discharged from the gas outlet 15. In other embodiments, the valve 151 can be set as a manual valve, and the opening or closing of the valve 151 is manually controlled. The utility model does not limit the specific structure of the valve 151 of the gas outlet 15.

[0027] Furthermore, a rotation slot 12 is also provided on the device body 10. Specifically, the rotation slot 12 is located on the side wall of the device body 10. The width of the rotation slot 12 matches the height of the filter assembly 20. It is understandable that the filter assembly 20 can pass through the rotation slot 12. Specifically, in this embodiment, the rotation slot 12 is an annular groove surrounding the side wall of the device body 10. The rotation slot 12 divides the device body 10 into an upper half 11 and a lower half 13.

[0028] The filter assembly 20 is disposed at the rotating notch 12 and is rotatably connected to the device body 10. Specifically, the edge of the filter assembly 20 is rotatably connected to the side wall of the device body 10. When the filter assembly 20 rotates relative to the device body 10, the filter assembly 20 can be rotated out of the processing chamber 16 through the rotating notch 12, and the filter assembly 20 can be cleaned at this time; when the filter assembly 20 is cleaned, the filter assembly 20 can be rotated back into the processing chamber 16 through the rotating notch 12.

[0029] Please combine Figure 2 , Figure 3 and Figure 4Specifically, in the present embodiment, the filter assembly 20 includes a filter plate 21 and a rotating mechanism 22. The filter plate 21 is provided with a filter hole 211 for passing the waste gas and filtering the waste gas. The axial direction of the filter hole 211 is consistent with the axial direction of the processing chamber 16. It can be understood that when the waste gas enters the processing chamber 16 from the air inlet 14, it continues to move downward to the filter plate 21, and the waste gas can pass through the filter plate 21 through the filter hole 211 to reach the bottom of the filter plate 21, while the large solid particles of impurities in the waste gas cannot pass through the filter plate 21 through the filter hole 211, and thus remain above the filter plate 21. When the waste gas treatment device 100 treats the waste gas for a long time, too many impurities accumulate on the filter plate 21, which is easy to clog the filter hole 211, so the filter plate 21 needs to be processed, and the filter plate 21 needs to be moved out of the processing chamber 16 for cleaning.

[0030] Therefore, the utility model enables the filter plate 21 to be rotated out of the processing chamber 16 by providing a rotating mechanism 22. Specifically, the rotating mechanism 22 is provided at the edge of the filter plate 21. One end of the rotating mechanism 22 is rotatably connected to the filter plate 21, and the other end of the rotating mechanism 22 is fixedly connected to the device body 10. In this embodiment, the rotating mechanism 22 and the filter plate 21 are both provided between the upper and lower side walls of the rotating slot 12. The side of the rotating mechanism 22 away from the filter plate 21 is fixedly connected to the lower side wall of the rotating slot 12.

[0031] Optionally, in this embodiment, a plurality of filter holes 211 are provided, and are radially arranged from the center of the filter plate 21 to the edge of the filter plate 21. In other embodiments, the arrangement of the filter holes 211 on the filter plate 21 can be a rectangular array, a staggered array, etc. As long as the exhaust gas can be filtered, the utility model does not limit the arrangement of the filter holes 211.

[0032] Furthermore, in order to achieve a better filtering effect, the shape of the filter plate 21 is the same as the cross-sectional shape of the device body 10. For example, in this embodiment, the device body 10 is cylindrical, and the shape of the filter plate 21 is a circular plate. When the filter plate 21 is screwed into the processing chamber 16, the edge size of the filter plate 21 can match the inner wall size of the processing chamber 16, so that the filter plate 21 can maximize the processing area of ​​the exhaust gas.

[0033] It can be understood that the filter plate 21 can rotate around the rotating mechanism 22, that is, the filter plate 21 can rotate around a point on its edge, and then gradually rotate out of the rotating slot 12 as the rotating angle increases.

[0034] In this embodiment, the rotating notch 12 is configured as an annular groove surrounding the device body 10, so the filter plate 21 can be rotated out of the processing chamber 16 by rotating clockwise around the rotating mechanism 22, and can also be rotated out of the processing chamber 16 by rotating counterclockwise. Similarly, the filter plate 21 can be rotated into the processing chamber 16 from the outside of the device body 10 by rotating clockwise around the rotating mechanism 22, and can also be rotated into the processing chamber 16 from the outside of the device body 10 by rotating counterclockwise around the rotating mechanism 22.

[0035] Furthermore, since the rotating notch 12 is set as an annular groove surrounding the device body 10, the device body 10 is divided into an upper half 11 and a lower half 13. Since the upper half 11 and the lower half 13 are arranged at intervals, the exhaust gas treatment device 100 in this embodiment also includes a connector (not shown) to fix the upper half 11 and the lower half 13 of the device body 10, and the connector does not interfere with the filter assembly 20, that is, it does not affect the filter assembly 20 from rotating in or out of the rotating notch 12. Specifically, in this embodiment, the connector is arranged on the outside of the device body 10, and the two ends of the connector are fixedly connected to the upper half 11 and the lower half 13 respectively. In other embodiments, the upper part 11 and the lower part 13 may be provided with connecting pieces to connect with other fixed structures respectively, so as to achieve relative fixation of the upper part 11 and the lower part 13, that is, the upper part 11 is connected to the external fixed structure through a connecting piece, and the lower part 13 is connected to the external fixed structure through another connecting piece, so as to achieve relative fixation of the upper part 11 and the lower part 13. As long as the relative fixation of the upper part 11 and the lower part 13 can be achieved, the present invention does not limit the structure of the connecting piece.

[0036] Furthermore, since the rotating notch 12 is set as an annular groove surrounding the device body 10, the device body 10 is divided into an upper half 11 and a lower half 13 by the rotating notch 12. When the filter assembly 20 is screwed into the processing chamber 16, there is still a gap below the filter assembly 20. Therefore, the exhaust gas treatment device 100 in this embodiment also includes a seal (not shown) for sealing the rotating notch 12 when the filter assembly 20 is screwed into the processing chamber 16. Specifically, in this embodiment, the seal is a rubber seal ring.

[0037] Please refer to Figure 4In this embodiment, the rotating mechanism 22 includes a rotating shaft 221, and the filter plate 21 can rotate around the axis of the rotating shaft 221. A circular hole 212 is provided on the edge of the filter plate 21. A sleeve 222 is fixedly connected to one end of the rotating shaft 221. The sleeve 222 is rotatably matched with the circular hole 212. It can be understood that the circular hole 212 is a countersunk hole, and when the sleeve 222 is inserted into the circular hole 212, the top of the sleeve 222 abuts against the bottom wall of the circular hole 212. The inner wall diameter of the circular hole 212 is clearance-matched with the outer wall diameter of the sleeve 222, so that the sleeve 222 can rotate in the circular hole 212, so that the rotating shaft 221 and the filter plate 21 can rotate relative to each other. One end of the rotating shaft 221 away from the sleeve 222 is fixedly connected to the device body 10. Specifically, one end of the rotating shaft 221 away from the sleeve 222 is fixedly connected to the lower wall of the rotating notch 12, so that the device body 10 and the filter plate 21 can rotate relative to each other.

[0038] In the present embodiment, the rotating shaft 221 includes a fixed rod 2211 and a movable rod 2212. One end of the fixed rod 2211 is fixedly connected to the device body 10. Specifically, one end of the fixed rod 2211 is fixedly connected to the lower wall of the rotating notch 12. One end of the movable rod 2212 is inserted into one end of the fixed rod 2211 close to the filter plate 21, and can move axially relative to the fixed rod 2211. Specifically, a hole is provided at one end of the fixed rod 2211 close to the filter plate 21, and one end of the movable rod 2212 is matched with the hole of the fixed rod 2211 to realize the axial hole. It can be understood that the movable rod 2212 can slide axially in the hole of the fixed rod 2211. Further, the movable rod 2212 and the fixed rod 2211 are circumferentially limited. Specifically, in the present embodiment, a strip protrusion (not shown) is provided axially on the outer wall of the movable rod 2212, and a strip groove (not shown) matching with the strip protrusion is provided on the inner wall of the hole of the fixed rod 2211. The strip-shaped protrusion and the strip-shaped groove cooperate to realize the circumferential limit of the movable rod 2212 and the fixed rod 2211, and limit the relative rotation of the movable rod 2212 and the fixed rod 2211. Optionally, in other embodiments, a strip-shaped groove can be provided on the outer wall of the movable rod 2212, and a strip-shaped protrusion can be provided on the inner wall of the hole of the fixed rod 2211. Alternatively, one end of the movable rod 2212 that cooperates with the fixed rod 2211 is a non-cylindrical structure. As long as the relative rotation of the movable rod 2212 and the fixed rod 2211 can be limited, the utility model does not limit this.

[0039] It is understandable that the axially movable structure of the movable rod 2212 and the fixed rod 2211 is to facilitate the filter plate 21 not to contact with the upper device body 10 when the filter plate 21 is rotated, so as to prevent friction from hindering the movement of the filter plate 21. The circumferential fixation of the movable rod 2212 and the fixed rod 2211 is to avoid relative rotation of the movable rod 2212 and the fixed rod 2211 and friction when the sleeve 222 and the circular hole 212 rotate relative to each other.

[0040] Please refer to Figure 1 and Figure 5 Furthermore, the exhaust gas treatment device 100 also includes a fixed plate 30. The fixed plate 30 is located in the rotating slot 12. One end of the fixed plate 30 is connected to the device body 10 through an elastic member 31, and the other end of the fixed plate 30 abuts against the filter plate 21. Specifically, the fixed plate 30 is located below the filter plate 21. It can be understood that when the filter plate 21 is screwed into the processing chamber 16, the fixed plate 30 abuts against the filter plate 21; when the filter plate 21 is screwed out of the processing chamber 16, the fixed plate 30 abuts against the edge of the filter plate 21 under the action of the elastic member 31, specifically abuts against the connection between the filter plate 21 and the rotating mechanism 22.

[0041] Specifically, in this embodiment, the fixing plate 30 is annular. Further, the outer diameter of the fixing plate 30 is the same as the diameter of the filter plate 21. It is understandable that when the filter plate 21 is screwed into the processing chamber 16, the fixing plate 30 only abuts against the edge of the filter plate 21. Since the fixing plate 30 is annular, the edge of the filter plate 21 is not provided with a filter hole 211. Therefore, when the fixing plate 30 abuts against the filter plate 21, the filter hole 211 of the filter plate 21 does not affect the filtering of the exhaust gas.

[0042] Furthermore, a clearance hole is provided on the fixed plate 30. The rotating mechanism 22 is fixedly connected to the device body 10 through the clearance hole. It can be understood that when the filter plate 21 rotates relative to the device body 10, the filter plate 21 and the rotating mechanism 22 may not contact the fixed plate 30. The setting of the fixed plate 30 does not affect the rotation of the filter plate 21. When the filter plate 21 rotates relative to the device body 10, the filter plate 21 is first pressed down, the filter plate 21 is separated from the abutment with the upper part 11, and the filter plate 21 is pulled to rotate. At this time, the rotating mechanism 22 is fixed on the lower part 13 and does not contact the fixed plate 30. It should be noted that due to the provision of the elastic member 31, the two ends of the elastic member 31 are fixedly connected to the fixed plate 30 and the lower wall of the rotating notch 12 respectively. The fixed plate 30 is always in abutment with the filter plate 21 during the rotation of the filter plate 21. The contact pressure between the fixing plate 30 and the filter plate 21 must satisfy the requirement that the friction between the fixing plate 30 and the filter plate 21 is small enough so that the filter plate 21 can rotate smoothly.

[0043] Optionally, in this embodiment, the elastic member 31 is a spring, and the two ends of the spring are respectively fixedly connected to the fixing plate 30 and the lower wall of the rotating slot 12. The number of springs is six, and they are respectively arranged at equal intervals along the edge of the fixing plate 30. In other embodiments, the number of elastic members 31 can be any number such as two, three, four, etc., and can be arranged at equal intervals or symmetrically. As long as the force can be uniform, it can be specifically arranged as needed, and the utility model does not limit this.

[0044] Please refer to Figure 2 In this embodiment, a vibrating member 40 is further provided in the processing chamber 16. The vibrating member 40 is connected to the filter assembly 20 so as to vibrate the filter assembly 20. Specifically, the vibrating member 40 includes a vibrating base 41 and a vibrating rod 42. The vibrating base 41 is fixedly disposed on the upper wall of the processing chamber 16. The two ends of the vibrating rod 42 are respectively connected to the vibrating base 41 and the filter assembly 20. The vibrating base 41 is used to drive the vibrating rod 42 to vibrate up and down. In order to achieve a better vibration effect, the vibrating member 40 is disposed at the center of the processing chamber 16, so as to directly apply a vibration force to the center of the filter assembly 20 and radiate to the edge of the filter assembly 20 to ensure the uniformity of the vibration effect.

[0045] It is understandable that the axially movable structure of the movable rod 2212 and the fixed rod 2211 is convenient for the filter plate 21 not to contact the upper device body 10 when the filter plate 21 is rotated, and can also drive the filter plate 21 to vibrate up and down when the vibration member 40 is started, so as to meet the matching relationship. The fixed plate 30 is connected to the device body 10 through the elastic member 31 in order to buffer the filter plate 21 when the vibration member 40 is started.

[0046] In order to further process the exhaust gas, an adsorption plate 60 is further provided between the gas outlet 15 and the filter assembly 20. The adsorption plate 60 is fixedly connected to the inner wall of the processing chamber 16. Specifically, the adsorption plate 60 is an activated carbon adsorption plate 60.

[0047] Furthermore, in order to apply power to the exhaust gas, a suction fan 50 is also provided at the air outlet 15. The suction fan 50 is provided with an air suction port 51, and the air suction port 51 is located at one end of the processing chamber 16 close to the air outlet 15, and a fan blade 52 is provided inside the air suction port 51. Specifically, the suction fan 50 is located at the bottom of the processing chamber 16, and is used to suck the exhaust gas from the air inlet 14 to the air outlet 15. On the way, the exhaust gas passes through the filter plate 21 and the adsorption plate 60 for processing, and finally discharged from the air outlet 15.

[0048] Please refer to Figure 3 A handle 23 is also provided on the outside of the filter assembly 20. When the filter assembly 20 is screwed into the processing chamber 16, the handle 23 is located on the outside of the device body 10.

[0049] In summary, the beneficial effects of the exhaust gas treatment device 100 of the embodiment of the utility model are:

[0050] The waste gas treatment device 100 of the utility model can remove the fixed impurities on the filter component 20 by rotating the filter component 20 out of the processing chamber 16, and then the cleaned filter component 20 is rotated into the processing chamber 16 through the rotating notch 12, so as to continue to be used, thereby improving the waste gas treatment efficiency. The utility model can conveniently clean the filter component 20, and prevent the accumulation of too many impurities on the filter component 20, which affects the waste gas treatment effect.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
