DETAILED DESCRIPTION

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 6 The waste gas collection device for waste gas treatment shown in the figure comprises a connecting pipe 1, which is placed horizontally, a dust collecting cover 2 is installed at the left end of the connecting pipe 1, a filtering mechanism 3 is installed in the middle of the connecting pipe 1, a rotating driving member 4 is installed on the outside of the filtering mechanism 3, and a receiving box 6 and a blowing box 7 are symmetrically installed on both sides of the filtering mechanism 3. When in use, the rotating driving member 4 drives the filtering mechanism 3 to rotate, and the blowing box 7 blows the dust accumulated on the filtering mechanism 3 into the receiving box 6, so as to realize the real-time automatic cleaning of the filtering mechanism 3.

[0026] like Figure 3 As shown, the filter mechanism 3 includes a filter cartridge 31, which is a cylindrical structure. A second annular baffle 33 is fixed to the right end of the filter cartridge 31, and eight guide wheels 34 are evenly fixed on the inner circumference of the second baffle 33. A rotating frame 35 is coaxially installed in the filter cartridge 31. The rotating frame 35 is cylindrical. The inner wall of the right end of the rotating frame 35 is provided with a mounting groove 351. The mounting groove 351 is distributed along the circumference of the rotating frame 35. The guide wheels 34 are clamped in the mounting groove 351, so that the rotating frame 35 can rotate around the axis of the filter cartridge 31. A step is provided on the inner wall of the left end of the rotating frame 35, and a filter screen 36 is clamped in the step.

[0027] like Figure 3 , Figure 5As shown, a first annular baffle 32 is fixed to the left end of the filter cartridge 31, and the inner diameter of the first baffle 32 is larger than the outer diameter of the filter screen 36 and smaller than the outer diameter of the rotating frame 35, so as to facilitate the installation of the filter screen 36 and reduce the dust-containing gas from passing through the outside of the rotating frame 35. Preferably, a sealing ring 37 made of polytetrafluoroethylene is fixed to the right side of the first baffle 32, and the right surface of the sealing ring 37 abuts against the left surface of the rotating frame 35 to further improve the sealing performance of the edge of the rotating frame 35. At the same time, due to the self-lubricating property of polytetrafluoroethylene, the rotation of the rotating frame 35 will not be interfered.

[0028] like Figure 1 , Figure 3 , Figure 5 , Figure 6 As shown, a rotating drive member 4 is installed on the outer side of the filter cartridge 31, and the rotating drive member 4 is connected to the rotating frame 35 through a transmission mechanism 5. The rotating drive member 4 is a motor, and the output shaft of the motor is parallel to the axis of the filter cartridge 31. The transmission mechanism 5 includes a ring gear 51 and a gear 52, the ring gear 51 is sleeved on the outer side of the rotating frame 35, the gear 52 is fixed on the output shaft of the motor, and the gear 52 is meshed with the ring gear 51. When the motor rotates, the gear 52 drives the gear 51 to rotate, so that the rotating frame 35 drives the filter screen 36 to rotate around its axis.

[0029] like Figure 2 , Figure 4 , Figure 5 As shown, the blow box 7 is a rectangular hollow box body, which is vertically installed at the bottom of the filter cartridge 31 on the right side of the filter screen 36. An air inlet pipe 71 is installed at the bottom of the blow box 7, and the air inlet pipe 71 passes through the filter cartridge 31 and communicates with the high-pressure air storage tank. A vertical slit-shaped air blowing port is opened at the left end of the blow box 7 to increase the blowing force of the air and ensure the cleaning ability of the filter screen 36. The height of the blow box 7 is greater than the radius of the filter screen 36 to achieve cleaning of the entire filter screen 36.

[0030] A clamping tube 61 is fixed to the bottom of the filter cartridge 31 at the left end of the filter screen 36. The clamping tube 61 penetrates the filter cartridge 31, and a dust box (not shown) is connected to the lower end of the clamping tube 61. The receiving box 6 is a rectangular hollow shell. The receiving box 6 can be detachably mounted on the clamping tube 61 so that the receiving box 6 is vertically mounted in the filter cartridge 31. A receiving port is provided on the right side of the receiving box 6. The receiving port is opposite to the air port, and the receiving port is larger than the air port to prevent the blown dust from overflowing from the edge of the receiving port. When the filter screen 36 needs to be replaced, the receiving box 6 can be removed from the clamping tube 61 to avoid interfering with the replacement of the filter screen 36.

[0031] The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages:

[0032] By installing the filter on a rotatable rotating frame and installing a blowing box and a receiving box on both sides of the filter, the filter can be automatically cleaned in real time without disassembling the filter, which reduces the labor intensity of workers and improves the efficiency of exhaust gas treatment.

[0033] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings.
