[0024] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0025] like Figures 1 to 4 As shown, a VOC waste gas treatment device in one embodiment of the utility model includes a filter box 11, and the filter box 11 is provided with an air inlet pipe 12 and an air outlet pipe 13 that are connected to the filter box 11. A plurality of filter screens 22 are provided in the filter box 11, and activated carbon 23 is provided on the filter screens 22. The side wall of the filter box 11 is provided with an installation groove 41 that matches the activated carbon 23, and a fixing plate 42 is fixedly connected in the installation groove 41.

[0026] Specifically, the air inlet pipe 12 transports the exhaust gas into the filter box 11, and the exhaust gas passes through the multiple layers of activated carbon 23, and is adsorbed and purified by the activated carbon 23. The purified exhaust gas is discharged through the air outlet pipe 13. The fixing plate 42 is removed from the mounting groove 41, and the activated carbon 23 can be pulled out of the filter box 11 through the mounting groove 41, so that the activated carbon 23 can be replaced easily.

[0027] The filter box 11 is circular, and a shaft rod 31 is movably connected to the center axis of the filter box 11 , and a partition plate 21 matching the inner diameter of the filter box 11 is fixedly connected to the shaft rod 31 .

[0028] Specifically, the shaft 31 is movably connected between the upper wall and the bottom wall of the filter box 11, and the shaft 31 can drive the partition 21 to rotate. The partition 21 separates the filter screen 22, and the separated filter screens 22 are evenly fixed on both sides of the partition 21. The partition 21 divides the filter box 11 into a semicircular filter box and a semicircular replacement box, and the intake pipe 12 can transport the exhaust gas into the semicircular filter box. The partition 21 is fixedly connected with a rotating rod 32, and the rotating rod 32 is fixedly connected with a handle 33.

[0029] More specifically, when the activated carbon 23 in the semicircular filter box needs to be replaced, the shaft 31 can be rotated by rotating the rod 32 and the handle 33, thereby driving the partition 21 to rotate. The partition 21 moves the activated carbon 23 in the semicircular filter box to the semicircular replacement box.

[0030] New activated carbon 23 is arranged on the filter screen 22 in the semicircular replacement box, and the new activated carbon 23 in the semicircular replacement box is moved to the semicircular filter box to filter the exhaust gas. As the partition 21 rotates 180°, the positions of the activated carbon 23 in the semicircular filter box and the activated carbon 23 in the semicircular replacement box are changed. The fixed plate 42 is located in the semicircular replacement box. By opening the fixed plate 42, the used activated carbon 23 in the semicircular replacement box can be replaced. The replacement is convenient without stopping the delivery of the exhaust gas.

[0031] A sealing plate 52 is provided in the filter box 11, and a sealing groove 51 matching the sealing plate 52 is fixedly connected to the partition 21. The sealing groove 51 is an elastic rubber pad, which can be snapped into the sealing plate 52 to increase the sealing performance of the partition 21 and prevent exhaust gas from leaking from the joint between the partition 21 and the inner wall of the filter box 11.

[0032] The fixing plate 42 is clamped in the mounting groove 41, so that the fixing plate 42 can be taken out from the mounting groove 41 easily.

[0033] A handle 43 is fixedly connected to the fixing plate 42. The fixing plate 42 can be easily moved by the handle 43.

[0034] The first air permeable hole 61 is provided in the topmost activated carbon 23. Since the exhaust gas passes through the topmost activated carbon 23 first, the topmost activated carbon 23 reaches the saturated state first, while the lower activated carbon 23 has not yet reached the saturated state. After the topmost activated carbon 23 reaches the saturated state, the exhaust gas is not easy to pass through the topmost activated carbon 23, thereby affecting the efficiency of exhaust gas treatment. When the topmost activated carbon 23 reaches the saturated state first, the exhaust gas can continue to move downward through the first air permeable hole 61.

[0035] The activated carbon 23 at the middle position is provided with a second air hole 62. When the activated carbon 23 at the middle position reaches a saturated state, the exhaust gas can continue to move downward through the second air hole 62. When all the activated carbon 23 reaches a saturated state, the activated carbon 23 can be replaced.

[0036] The partition plate 21 is provided with a plurality of fixing grooves 71. The filter screen 22 is fixedly connected with a fixing block matching the fixing grooves 71, so as to facilitate the installation and removal of the filter screen 22. The number of the filter screens 22 can be increased or decreased according to the content of the exhaust gas, thereby increasing or decreasing the number of the activated carbon 23.

[0037] The height of the mounting groove 41 is greater than the height of the activated carbon 23, so that the activated carbon 23 can be easily taken out.

[0038] When using, refer to Figure 1 to Figure 4As shown, VOC waste gas is transported to the semicircular filter box through the air inlet pipe 12, and the VOC waste gas is adsorbed and purified by the activated carbon 23 in the semicircular filter box, and the purified waste gas is discharged through the air outlet pipe 13. When the activated carbon 23 in the semicircular filter box needs to be replaced, the shaft 31 can be rotated by the rotating rod 32 and the handle 33, and the shaft 31 drives the partition 21 to rotate. The partition 21 moves the activated carbon 23 in the semicircular filter box to the semicircular replacement box, and at the same time, the new activated carbon 23 in the semicircular replacement box is moved to the semicircular filter box for use. Open the fixing plate 42, the installation groove 41 leaks out, and the used activated carbon 23 in the semicircular replacement box can be taken out through the installation groove 41.

[0039] Compared with the prior art, the VOC waste gas treatment device of the utility model is convenient for replacing activated carbon, and there is no need to stop the transportation of waste gas during replacement, thereby increasing the efficiency of waste gas treatment.
