[0001] The utility model relates to the field of waste gas treatment, in particular to a VOCs waste gas treatment device based on zeolite wheel adsorption. Background Technique

[0002] Zeolite wheel adsorption is a technology that uses the special structure of the zeolite wheel and the adsorption characteristics of zeolite to adsorb pollutants. The zeolite wheel utilizes the advantages of high adsorption efficiency and fast desorption of zeolite to concentrate high-volume and low-concentration organic waste gas into low-volume and high-concentration waste gas, thereby reducing equipment investment costs and operating costs and improving the high-efficiency treatment of VOCs waste gas.

[0003] Zeolite wheels are widely used in the chemical industry, especially in the field of waste gas treatment. In the prior art, during the long-term use of zeolite wheels, their adsorption capacity will gradually decline. If they are not replaced or maintained in time, the waste gas treatment effect of the entire waste gas treatment device will be weakened. Moreover, zeolite wheels are usually fixed to the support plate with bolts, which is inconvenient for disassembly and assembly. Content of the Utility Model

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A VOCs waste gas treatment device based on zeolite wheel adsorption, including an adsorption chamber, a motor is fixedly connected to the bottom of the adsorption chamber, an output end of the motor is fixedly connected to a rotating shaft, a support plate is fixedly connected to an outer wall of the rotating shaft, a zeolite wheel is arranged on a top of the support plate, the zeolite wheel is sleeved on the outer wall of the rotating shaft, a rotating groove is opened at a top of the rotating shaft, a telescopic groove is opened at a bottom of an inner wall of the rotating groove, and the number of the telescopic grooves is multiple. A limiting groove is opened at an upper end of the inner wall of the rotating groove. A rotating rod is movably connected to a bottom of the inner wall of the rotating groove.

Positioning columns are fixedly connected to the bottom of the zeolite wheel, and the number of the positioning columns is multiple. Multiple positioning columns are respectively located inside the multiple positioning grooves.

[0008] As a further description of the above technical solution:

[0009] A top cover is provided at the top of the adsorption bin, a sealing groove is provided at the joint where the top cover fits with the top of the adsorption bin, and a sealing ring is installed inside the sealing groove.

[0010] As a further description of the above technical solution:

[0011] An air inlet is fixedly connected to the upper end of the left outer wall of the adsorption bin, and an air outlet is fixedly connected to the lower end of the right outer wall of the adsorption bin.

When the turntable rotates counterclockwise, the multiple linkage columns connected to its bottom respectively move along the linkage grooves opened inside the multiple telescopic blocks, so that the multiple telescopic blocks respectively move towards the center of the rotating shaft along the multiple telescopic grooves opened on the outer wall of the rotating shaft until the multiple telescopic blocks are respectively retracted into the rotating grooves opened at the top of the rotating shaft. Subsequently, the zeolite rotor can be lifted upward to separate the zeolite rotor from the rotating shaft, and a new or maintained zeolite rotor can be sleeved on the rotating shaft again. And the zeolite rotor is located on the top of the support plate. Subsequently, turn the knob clockwise, and by the same principle, the multiple telescopic blocks are reset to limit the movement of the zeolite rotor in the Y-axis direction, and the multiple telescopic blocks limit the zeolite rotor. The whole maintenance or replacement process is convenient and fast, avoiding the weakening of the adsorption effect due to the reduction of the adsorption performance of the zeolite rotor over time.

A limiting block 10 is fixedly connected to an outer wall of the rotating rod 9, and the number of the limiting blocks 10 is multiple. A plurality of the limiting blocks 10 are all located inside the limiting groove 8. A knob 11 is fixedly connected to a top of the rotating rod 9.

A telescopic block 14 is installed inside each of the plurality of telescopic grooves 7. A linkage groove 15 is opened inside the telescopic block 14, and the linkage column 13 is located inside the linkage groove 15.

[0030] When it is necessary to replace or maintain the zeolite wheel 5, rotate the knob 11 counterclockwise, and the rotating rod 9 and the turntable 12 rotate counterclockwise accordingly. When the turntable 12 rotates counterclockwise, a plurality of linkage columns 13 connected to its bottom respectively move along the linkage grooves 15 opened inside the plurality of telescopic blocks 14, so that the plurality of telescopic blocks 14 respectively move towards the center of the rotating shaft 3 along the plurality of telescopic grooves 7 opened on the outer wall of the rotating shaft 3 until the plurality of telescopic blocks 14 are respectively retracted into the rotating groove 6 opened at the top of the rotating shaft 3. Subsequently, the zeolite wheel 5 can be lifted upwards to separate the zeolite wheel 5 from the rotating shaft 3. Then, a new or maintained zeolite wheel 5 is sleeved on the rotating shaft 3 again, and the zeolite wheel 5 is located on the top of the support plate 4. Subsequently, rotate the knob 11 clockwise, and by the same principle, the plurality of telescopic blocks 14 are reset to limit the movement of the zeolite wheel 5 in the Y-axis direction. The plurality of telescopic blocks 14 limit the zeolite wheel 5, and the whole maintenance or replacement process is convenient and fast.

[0031] A positioning groove 16 is opened at a top of the support plate 4, and the number of the positioning grooves 16 is multiple. A positioning column 17 is fixedly connected to a bottom of the zeolite wheel 5, and the number of the positioning columns 17 is multiple. A plurality of the positioning columns 17 are respectively located inside the plurality of positioning grooves 16. The plurality of positioning columns 17 and the plurality of telescopic blocks 14 cooperate together to limit the movement of the zeolite wheel 5 in the X-axis and Y-axis directions.

[0032] A top cover 18 is arranged on a top of the adsorption chamber 1. A sealing groove 19 is opened at a joint between the top cover 18 and the top of the adsorption chamber 1.

[0034] Working principle:

[0035] The operation of the motor 2 drives the rotation of the rotating shaft 3. The rotation of the rotating shaft 3 drives the rotation of the support plate 4 connected to its outer wall. Since multiple positioning columns 17 connected to the bottom of the zeolite wheel 5 are respectively located in multiple positioning grooves 16 opened on the top of the support plate 4, and one end of multiple telescopic blocks 14 far from the center of the rotating shaft 3 extends outside the telescopic grooves 7, the movement of the zeolite wheel 5 in the X-axis and Y-axis directions is restricted, enabling the zeolite wheel 5 to rotate with the operation of the motor 2. When the zeolite wheel 5 needs to be replaced or maintained, rotate the knob 11 counterclockwise, and the rotating rod 9 and the turntable 12 rotate counterclockwise accordingly. When the turntable 12 rotates counterclockwise, multiple linkage columns 13 connected to its bottom respectively move along the linkage grooves 15 opened inside multiple telescopic blocks 14, causing multiple telescopic blocks 14 to move towards the center of the rotating shaft 3 along multiple telescopic grooves 7 opened on the outer wall of the rotating shaft 3 until multiple telescopic blocks 14 are respectively retracted into the rotating grooves 6 opened on the top of the rotating shaft 3. Subsequently, the zeolite wheel 5 can be lifted upwards to disengage the zeolite wheel 5 from the rotating shaft. Then, a new or maintained zeolite wheel 5 is sleeved on the rotating shaft 3 again, and the zeolite wheel 5 is located on the top of the support plate 4. Subsequently, rotate the knob 11 clockwise, and by the same principle, multiple telescopic blocks 14 return to their positions, restricting the movement of the zeolite wheel 5 in the Y-axis direction. Multiple telescopic blocks 14 limit the zeolite wheel 5, making the entire maintenance or replacement process convenient and fast.
