Description

Technical Field

[0001] The present application relates to the technical field of purification equipment, and in particular to an industrial gas purification equipment containing a filtering structure. Background Art

[0002] Activated carbon adsorption tower is an industrial gas purification equipment that uses the adsorption capacity of activated carbon to purify waste gas and wastewater. It is widely used in air purification and waste gas treatment in industrial production. For example, in chemical plants, pharmaceutical plants, printing plants, paint plants, food processing plants and other places, activated carbon adsorption towers can effectively remove harmful substances in waste gas, protect the environment and comply with environmental protection policy requirements.

[0003] Patent publication number CN117679860A discloses an activated carbon adsorption device for waste rubber recycling, which uses absorbent cotton to absorb and dry gas, and squeezes the absorbent cotton through a squeezing roller to dehydrate and reuse the absorbent cotton. However, the above structure has the following problems:

[0004] 1. The absorbent cotton is provided as a single, large-sized, single integral structure, and the reciprocating movement and squeezing of the absorbent cotton easily causes the absorbent cotton to wrinkle or even stack together.

[0005] 2. The squeezing roller needs to move a long distance, which takes a long time.

[0006] 3. The power device, i.e. the first reduction motor, is located at the top of the adsorption tower. Disassembly, assembly and maintenance require climbing to the top of the adsorption tower, which is extremely inconvenient.

[0007] Therefore, it is necessary to design a liquid supply gas purification device that can achieve dehydration of the water filter equipment over a short distance. Summary of the invention

[0008] An industrial gas purification device with a filtering structure includes an adsorption bed body, wherein the adsorption bed body at least includes a frame and an activated carbon filtering device arranged in the frame, and further includes:

[0009] The water filter assembly is arranged on the right half of the frame along the front-back direction, and comprises a fixed frame, a water filter element arranged in the fixed frame, and a sliding frame slidably arranged on the fixed frame, wherein the sliding frame moves horizontally to squeeze the water filter element;

The crank assembly drives the nut assembly to rotate, and the nut assembly drives the lead screw assembly to move forward and backward and drives the sliding frame to move forward and backward.

[0015] As a further implementation:

[0016] The mounting base includes an upper mounting column arranged at the upper end of the frame, an upper horizontal column arranged below the rear end surface of the upper mounting column, a front mounting column arranged at the front end of the frame, a lower horizontal column arranged behind the front mounting column, and a rotation-stopping longitudinal column connecting the upper horizontal column and the lower horizontal column. The mounting base also includes an upper connecting block arranged at the lower end surface of the upper horizontal column, a lower connecting block arranged at the upper end surface of the lower horizontal column, a limiting circular ring fixedly connected between the upper connecting block and the lower connecting block, and a limiting ring groove formed on the inner wall of the limiting circular ring;

[0017] The nut assembly includes an upper rotating hole provided at the lower end of the upper mounting column, a lower rotating hole provided at the upper end surface of the front mounting column, a rotating central shaft rotatably provided between the upper rotating hole and the lower rotating hole, an active bevel gear provided on the rotating central shaft and between the upper mounting column and the front mounting column, a bottom bevel gear provided at the lower end of the rotating central shaft, an internally threaded tube rotatably provided in the limiting circular ring, a limiting convex ring provided on the outer wall of the internally threaded tube and rotatably matched with the limiting ring groove, and a driven bevel gear provided on the right side of the internally threaded tube and meshing with the active bevel gear;

[0019] The crank assembly is arranged in the front mounting column to drive the bottom bevel gear to rotate.

[0020] As a further implementation:

[0021] The crank assembly includes a crank circular cavity arranged in the front mounting column, a rear end opening arranged behind the front mounting column and connected to the lower rotating hole, a front end opening arranged at the front end of the crank circular cavity, a crank circular shaft rotatably arranged in the crank circular cavity, a gear shaft penetrating the rear end opening is provided at the rear end of the crank circular shaft, and a crank bevel gear is provided on the gear shaft, the crank bevel gear is transmission-connected with the bottom bevel gear, the crank assembly also includes a crank front cavity arranged at the front end of the crank circular shaft, axial side holes uniformly distributed on the outer wall of the crank front cavity in the circumferential direction, a widened circular groove formed on the inner wall of the crank circular cavity, a fixed locking ring formed in front of the widened circular groove, a compression spring and a movable locking ring are sequentially arranged in the widened circular groove from back to front, the crank assembly also includes a through plug plate uniformly distributed on the inner wall of the movable locking ring in the circumferential direction and plugged into the corresponding axial side holes one by one, a telescopic core shaft slidably arranged in the crank front cavity and connected to the through plug plate, a vertical connecting rod perpendicular to the front end of the telescopic core shaft, and a hand-held handle arranged in front of the stop end of the vertical connecting rod.

[0026] Beneficial effects:

[0027] A purification device described in this case arranges multiple water filter elements between a fixed frame and a sliding frame. The size of the water filter elements in the front-to-back direction is greatly reduced. After multiple squeezing in the front-to-back direction, the deformation of the water filter elements is small, thereby reducing the wrinkle deformation of the water filter elements as much as possible.

[0028] The purification equipment described in this case has a small displacement distance of the water filter assembly and a high dehydration efficiency: the water filter assembly can move a small distance forward and backward through the sliding frame, and the follower pressure plate can synchronously squeeze and dehydrate multiple water filter elements. The moving distance of the sliding frame in the forward and backward direction does not exceed the size of the accommodating through hole in the forward and backward direction, which greatly reduces the action distance and improves the dehydration efficiency.

[0029] The purification equipment described in this case has a crank component of the displacement assembly arranged in front of the frame and located in the lower half of the frame in the height direction, so as to facilitate manual rotation operation. BRIEF DESCRIPTION OF THE DRAWINGS
