In the description of the present utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically limited.

[0029] like Figure 1-5 As shown, the utility model provides a homogenizing adsorption device for VOC waste gas, including a base 10, an outer cylinder 11, a cover body 12, a rotating shaft 20, an adsorption cylinder 30 and a driving mechanism 40.

[0030] The base 10 is disc-shaped, and a plurality of legs 13 are fixedly mounted on the bottom of the base 10. The base 10 is provided with a plurality of annular positioning grooves 14 extending downward, and the plurality of annular positioning grooves 14 are arranged in sequence and at equal intervals along the circumference of the base 10.

[0031] The outer cylinder 11 is fixedly mounted on the base 10 along the longitudinal direction, and an air outlet pipe 15 communicating with the interior of the outer cylinder 11 is fixedly mounted on the outer surface of the outer cylinder 11 .

[0032] The cover body 12 is arranged on the top of the outer tube 11, the first side of the cover body 12 is hinged to the first side of the outer tube 11, and the second side of the cover body 12 is threadedly connected to the second side of the outer tube 11. A cavity is formed inside the cover body 12, and an air inlet pipe 16 connected to the cavity is fixedly installed on the top of the cover body 12. A plurality of inserting tubes 17 are fixedly installed on the bottom of the cover body 12, and the plurality of inserting tubes 17 correspond to the plurality of annular positioning grooves 14 one by one.

[0033] There are multiple rotating shafts 20, which correspond to the multiple annular positioning grooves 14 one by one, and the rotating shafts 20 are arranged in the middle of the corresponding annular positioning grooves 14. The rotating shafts 20 pass through the base 10 in the longitudinal direction and are rotatably connected to the base 10. A plurality of blades 21 are fixedly mounted on the rotating shafts 20, and the blades 21 are located inside the outer cylinder 11.

[0034] There are multiple adsorption cylinders 30 , and the multiple adsorption cylinders 30 correspond to the multiple annular positioning grooves 14 . The lower end of the adsorption cylinder 30 is adapted to the corresponding annular positioning groove 14 , and the upper end of the adsorption cylinder 30 is adapted to the corresponding insertion tube 17 .

[0035] The driving mechanism 40 is used to control the multiple rotating shafts 20 to rotate simultaneously.

[0036] In the initial state, the cover body 12 is closed on the top of the outer tube 11 , the lower end of the adsorption tube 30 is inserted into the corresponding annular positioning groove 14 , and the upper end of the adsorption tube 30 is inserted into the corresponding insertion tube 17 .

[0037] The specific working process of the device is as follows: First, the driving mechanism 40 starts to control the multiple rotating shafts 20 to rotate simultaneously, and the blades 21 on the rotating shafts 20 will generate airflow in the adsorption cylinder 30. Then, the VOC waste gas enters the cavity through the air inlet pipe 16, and enters the multiple adsorption cylinders 30 through the multiple inserts 17. At this time, the rotation of the blades 21 homogenizes the VOC waste gas and improves the fluidity of the VOC waste gas. Then, under the action of pressure, the VOC waste gas passes through the adsorption cylinder 30 into the outer cylinder 11, and is finally discharged from the outlet pipe 15.

[0038] On the one hand, the device can divert VOC waste gas into multiple adsorption cylinders 30, thereby improving the adsorption efficiency of VOC waste gas; on the other hand, the rotation of the blades 21 homogenizes the VOC waste gas, improves the fluidity of the VOC waste gas, and thus can improve the adsorption effect of the adsorption cylinder 30 on the VOC waste gas.

[0039] In one embodiment, the driving mechanism 40 includes a connecting shaft 41 , a first gear 42 , a motor 43 and a plurality of second gears 44 .

[0040] The connecting shaft 41 is disposed longitudinally below the base 10 and is rotatably connected to the base 10, and the axis of the connecting shaft 41 is colinear with the axis of the base 10. The first gear 42 is fixedly mounted on the connecting shaft 41. The motor 43 is fixedly mounted on the base 10 through the mounting bracket 45 and is used to drive the connecting shaft 41 to rotate. The motor 43 is electrically connected to the external control cabinet. A plurality of second gears 44 are respectively fixedly mounted on the plurality of rotating shafts 20 and are all meshed with the first gear 42.

[0041] When the driving mechanism 40 is working, the external control cabinet controls the motor 43 to start, and the motor 43 drives the connecting shaft 41 and the first gear 42 to rotate, and then drives the second gear 44 and the corresponding rotating shaft 20 to rotate. The blades 21 on the rotating shaft 20 will generate airflow in the adsorption cylinder 30, further improving the adsorption effect of the adsorption cylinder 30 on VOC waste gas.

[0042] In one embodiment, the axis of the rotating shaft 20 is colinear with the axis of the annular positioning groove 14 .

[0043] In one embodiment, a first sealing ring 18 is fixedly mounted on the inner wall of the annular positioning groove 14 , a second sealing ring 19 is sleeved on the insertion tube 17 , and the second sealing ring 19 is fixedly connected to the cover body 12 .

[0044] Thus, when the device is in the initial state, the upper end and the lower end of the adsorption cylinder 30 are sealed by the first sealing ring 18 and the second sealing ring 19 to prevent the VOC waste gas that has not been adsorbed from overflowing.

[0045] In one embodiment, a first valve is fixedly installed on the air inlet pipe 16 , and a second valve is fixedly installed on the air outlet pipe 15 .

[0046] After the device has been used for a period of time, the adsorption efficiency of the adsorption cylinder 30 decreases, and the staff needs to replace the adsorption cylinder 30. At this time, the staff opens the first valve and the second valve to prevent VOC waste gas from continuing to enter, opens the cover 12 to take out the original adsorption cylinder 30, and inserts the lower end of the new adsorption cylinder 30 into the annular positioning groove 14, and then covers the cover 12.

[0047] In one embodiment, the adsorption cylinder 30 is filled with molecular sieve particles or activated carbon particles.

[0048] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.

[0049] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
