[0044] The guide device 62 includes a limit card shaft 624 for support, a transmission worm gear 623 is fixedly installed at the center of the outer end surface of the limit card shaft 624, and a connecting turntable 621 is symmetrically arranged on the side end surface of the limit card shaft 624, and a fixed sliding shaft 622 is fixedly arranged on the side end surface of the two sets of connecting turntables 621 near the outside.

[0045] The limiting shaft 311 is rotatably connected to the inner end surface of the closed cover plate 32 through the fixed rotating groove 31. The inner end surface of the limiting shaft 311 is hollow. The hollow setting inside the limiting shaft 311 can facilitate subsequent wiring, and can also facilitate the subsequent connection between the line body and the electric slip ring 312.

[0046] The four sets of driven gears 310 are all meshed and connected with the driving gear 34, and the four sets of driven gears 310 are all meshed and connected with the transmission ring gear 35. Under the meshing of the driving gear 34 and the transmission ring gear 35, the four sets of driven gears 310 can rotate at high speed and also rotate in a circle, which can effectively improve the efficiency of exhaust gas treatment.

[0047] Both sets of exhaust ducts 45 are fixedly connected to the fixed ducts 38, the support guide shaft 53 is adapted to the sealing slide groove 46, and the compression card plate 54 is adapted to the sealing slide groove 46 through the support guide shaft 53 and then sealed and slidably clamped on the inner end surface of the air guide box 41. The sealed sliding adaptation of the support guide shaft 53 and the sealing slide groove 46 can effectively improve the accuracy of the compression card plate 54 in compressing and guiding the gas inside the air guide box 41.

[0048] The width of the fixed slide rail 51 is equal to the diameter of the fixed slide shaft 622, and the connecting turntable 621 is adapted to the fixed slide rail 51 through the fixed slide shaft 622 and then slidably engaged with the guide slide groove 52. When the fixed slide shaft 622 rotates in a circle, it can limit the sliding of the fixed slide rail 51, and then synchronously drive the two sets of compression clamping plates 54 to move up and down inside the air guide box 41, which can effectively improve the stability of equal air guidance of exhaust gas.

[0049] The transmission worm 68 is meshedly connected with the transmission worm wheel 623, and the active synchronous pulley 63 is meshedly connected with the driven synchronous pulley 7 through the arc-toothed synchronous belt 2. The meshing of the transmission worm 68 and 323 can effectively improve the stability of subsequent transmission. At the same time, the transmission card shaft 69 can synchronously provide power to the quantitative air guide device 4 and the exhaust gas treatment device 3 through the transmission worm 68 and the active synchronous pulley 63, which can effectively improve the power utilization efficiency of the equipment.

[0050] Working principle: Before use, the user can connect the external exhaust gas supply pipeline with the air supply conduit 43 to facilitate the subsequent rapid air supply operation of the VOCs exhaust gas. At the same time, the external exhaust pipeline can be connected to the bottom of the exhaust branch pipe 314 to facilitate the subsequent extraction of the treated exhaust gas for further treatment.

[0051] When treating the exhaust gas, the user can start the servo motor 61, and the servo motor 61 can drive the transmission card shaft 69 at the bottom to rotate, and the transmission card shaft 69 can synchronously drive the transmission worm 68 and the active synchronous pulley 63 to rotate.

[0052] When the transmission worm 68 rotates, the transmission worm 68 can drive the front transmission worm wheel 623 to mesh and rotate, and at the same time, the transmission worm wheel 623 can synchronously drive the two sets of connecting turntables 621 to rotate in a circle, and the two sets of connecting turntables 621 can drive the fixed sliding shaft 622 to rotate in a circle, and the fixed sliding shaft 622 can pass through the sliding limit with the fixed slide rail 51, and then synchronously drive the two sets of guide slide grooves 52 to move up and down in a cycle. When the guide slide groove 52 moves up and down, the guide slide groove 52 can drive the compression card plate 54 through the support guide shaft 53. When the compression card plate 54 moves up and down inside the air guide box 41, the second one-way valve 42 is opened and the third one-way valve 44 is closed. At this time, the inside of the air guide box 41 is in negative pressure, and the exhaust gas can be sucked in an equal amount through the air supply duct 43. On the contrary, the compression card plate 54 introduces the exhaust gas into the fixed duct 38 through the exhaust duct 45, thereby completing the equal introduction of the exhaust gas. At the same time, when the intermittent introduction is performed, it can provide sufficient time for the exhaust gas treatment device 3 to subsequently treat the exhaust gas, thereby maximizing the efficiency of the exhaust gas treatment device 3 in treating the exhaust gas.

[0053] When the above-mentioned active synchronous pulley 63 rotates synchronously, the active synchronous pulley 63 can drive the limiting shaft 311 to rotate through the arc-shaped toothed synchronous belt 2, and the limiting shaft 311 can drive the bottom active gear 34 to rotate, and the active gear 34 can synchronously drive the four sets of driven gears 310 to rotate, and the four sets of driven gears 310 can mesh with the transmission gear ring 35, so that the four sets of driven gears 310 can not only rotate in a circle, but also rotate at a high speed, so that the four sets of heating wires 39 can contact the exhaust gas to the greatest extent. When rotating again, the external wire can be connected to the electric slip ring 312 through the upper opening of the limiting shaft 311, and the electric slip ring 312 can supply power to the heating wire 39 through the limiting rotating seat 33 for rapid heating, thereby improving the efficiency of exhaust gas treatment, treating subsequent exhaust gas, and when the first one-way valve 313 reaches a certain pressure, it automatically opens, and then the exhaust gas is discharged through the exhaust branch pipe 314.
