Description

Technical Field

[0001] The utility model relates to the technical field of environmental engineering, in particular to an environment-friendly waste gas treatment device. Background Art

[0002] At present, in the operation of waste gas treatment for dust, as a common filtering solution, a filter screen is widely used to remove dust particles in waste gas. Through its dense filter hole structure, the filter screen can effectively intercept and adsorb dust in waste gas, thereby realizing the preliminary purification of waste gas.

[0003] However, with the increase of the use time, the dust on the filter screen gradually accumulates, the filter holes are gradually blocked, resulting in the gradual reduction of the filtering effect and even complete failure. This not only affects the efficiency of waste gas treatment, but also may cause the treated waste gas to still not meet the emission standard, further aggravating environmental pollution. Therefore, in view of this problem, the utility model proposes an environment-friendly waste gas treatment device. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an environment-friendly waste gas treatment device that can overcome the above problems or at least partially solve the above problems.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: An environment-friendly waste gas treatment device includes a tank body for waste gas treatment. One end of the tank body is connected with an air inlet cover, and the other end is connected with an air outlet cover. A filter plate is connected inside the tank body. The device further includes a mounting rack installed on the inner wall of the tank body. A connecting shaft one is rotatably provided on the mounting rack. A plurality of fan blades distributed in a circular pattern and located inside the mounting rack are fixed on the connecting shaft one. The connecting shaft one extends to one end of the filter plate close to the left side and is detachably connected with a brush plate that fits on the surface of the filter plate. The bottom of the tank body is communicated with a slag discharging part that can be opened or closed, which is used to cooperate with the dust and impurities generated by the brush plate when cleaning the surface of the filter plate for discharging.

[0006] Preferably, when the brush plate and the connecting shaft one are in a detachable elastic clamping structure, the brush plate is provided with a mounting hole that fits on the surface of the connecting shaft one. One end of the connecting shaft one close to the filter plate is provided with a circular groove, and the inner wall of the circular groove is provided with a plurality of clamping grooves distributed in a circular pattern.

[0007] Preferably, the clamping part includes a positioning piece fixed on the brush plate and fitting on the surface of the connecting shaft one. An L-shaped elastic piece that clamps on the inner wall of the circular groove is fixed on the positioning piece. A clamping block that fits on the inner wall of the clamping groove is fixed on the L-shaped elastic piece.

[0008] Preferably, the slag discharging member includes a slag discharging shell fixed on the tank body. An upright cavity and a circular cavity which are communicated with each other are sequentially arranged in the slag discharging shell from top to bottom. The upright cavity is communicated with the interior of the tank body. A discharge port is arranged at the bottom of the circular cavity. A second connecting shaft is rotatably connected to the slag discharging shell.

[0019] The following further describes the present invention in detail with reference to the drawings and embodiments, so that those skilled in the art can implement it according to the description in the specification.

[0020] It should be understood that the terms such as "having", "including" and "comprising" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0021] In the description of the present invention, the orientation or positional relationship indicated by the terms "transverse", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0022] Embodiment 1: Refer to Figure 1 、 Figure 2 and Figure 5 , an environment-friendly waste gas treatment device, including a tank body 1 for waste gas treatment. A pair of arc-shaped supporting blocks 5 are fixed at the bottom of the tank body 1. A pair of support plates 51 are fixed at the bottom of the arc-shaped supporting blocks 5. A bottom plate 52 is fixed at the bottom of the support plates 51. Corresponding connecting holes 53 are provided near the four corners of the bottom plate 52 for fixing the device at the required position. The connecting holes 53 are circular. An air inlet cover 11 is connected to one end of the tank body 1, and an air outlet cover 12 is connected to the other end. A filter plate 13 is connected inside the tank body 1. It further includes a mounting rack 2 installed on the inner wall of the tank body 1. A first connecting shaft 21 is rotatably provided on the mounting rack 2. A plurality of fan blades 22 distributed in a circular pattern and located inside the mounting rack 2 are fixed on the first connecting shaft 21. The first connecting shaft 21 extends to one end of the filter plate 13 near the left side and is detachably connected to a brush plate 23 that fits the surface of the filter plate 13.

[0023] In the above technical solution, when the first connecting shaft 21 is driven by the servo motor installed on the mounting frame 2, it will drive the fan blade 22 to rotate, generating negative pressure in the tank body 1 to suck dust in the external environment into the tank body 1 for filtration through the filter plate 13, and the filtered gas is then discharged from the air outlet cover 12. This can reduce the pollution of environmental dust. At the same time, considering that the dust and impurities on the filter plate 13 will affect the filtering effect of the filter plate 13, the first connecting shaft 21 will also drive the brush plate 23 to synchronously clean the side of the filter plate 13 close to the air inlet cover 11 during the rotation process. This design avoids the cumbersome problem of the traditional method of disassembling and cleaning the filter plate 13 from the tank body 1.

[0024] Further, referring to Figure 2 and Figure 3 , considering that after the brush plate 23 automatically cleans the dust or impurities on the surface of the filter plate 13, although it avoids the cumbersome problem of manual disassembly and cleaning of the filter plate, the cleaned dust is inconvenient to discharge and will accumulate in the tank body 1, which may cause the dust after cleaning to adhere to the filter plate 13 again. Therefore, based on this problem, a slag discharging part 3 that can be opened or closed is connected to the bottom of the tank body 1 to cooperate with the brush plate 23 to discharge the dust and impurities generated on the surface of the filter plate 13. The slag discharging part 3 includes a slag discharging shell 31 fixed on the tank body 1. An upright cavity 32 and a circular cavity 33 that are connected to each other are sequentially arranged in the slag discharging shell 31 from top to bottom. The upright cavity 32 communicates with the inside of the tank body 1, and a discharge port 34 is provided at the bottom of the circular cavity 33. A second connecting shaft 35 is rotatably connected to the slag discharging shell 31, and a plurality of blades 36 that are circumferentially distributed and are all in contact with the inner wall of the circular cavity 33 are fixed on the second connecting shaft 35. The right side wall of the upright cavity 32 is on the same horizontal plane as the side of the filter plate 13 for filtration. When the slag discharging part 3 realizes the discharge of dust and impurities, only need to start the servo motor on the slag discharging shell 31 to drive the blades 36 fixed on the second connecting shaft 35 to slide along the inner wall of the circular cavity 33, and the dust and impurities accumulated between the upright cavity 32 and the circular cavity 33 can be discharged and processed.

[0025] Embodiment 2: Referring to Figure 4 , on the basis of the above Embodiment 1, when the brush plate 23 and the first connecting shaft 21 are of a detachable elastic clamping structure, the brush plate 23 is provided with a mounting hole 26 that fits the surface of the first connecting shaft 21. One end of the first connecting shaft 21 close to the filter plate 13 is provided with a circular groove 24, and a plurality of clamping grooves 25 are arranged on the inner wall of the circular groove 24 in a circumferential distribution. A clamping part 4 that cooperates with the plurality of clamping grooves 25 is fixed on the brush plate 23. The clamping part 4 includes a positioning piece 41 fixed on the brush plate 23 and fitting the surface of the first connecting shaft 21. An L-shaped elastic piece 42 that clamps the inner wall of the circular groove 24 is fixed on the positioning piece 41, and a clamping block 43 that fits the inner wall of the clamping groove 25 is fixed on the L-shaped elastic piece 42.

[0026] In the above technical solution, the mounting hole 26 on the brush plate 23 slides along one end of the connecting shaft 21 located on the filter plate 13. While the brush plate 23 slides, it will also drive the positioning piece 41 to slide and fit along the surface of the connecting shaft 21, so that the L-shaped elastic piece 42 connected to the positioning piece 41 can slide and clamp along the inner wall of the circular groove 24. At the same time, the clamping block 43 on the L-shaped elastic piece 42 is tightly clamped in the clamping groove 25. Such a design can facilitate the subsequent replacement of the brush plate 23. When replacing, only need to remove the bolts connecting the air inlet cover 11 and the tank body 1, separate the air inlet cover 11 from the tank body 1, and then pull the clamping portion 4 on the brush plate 23 to slide out of the circular groove 24.

[0027] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
