[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0021] Reference Figure 1-4 A device for recovering tail gas adsorption solvent includes a recovery barrel 1, a collecting barrel 2 is fixedly inserted inside the recovery barrel 1, the collecting barrel 2 opens upward, a filtering mechanism is arranged above the collecting barrel 2, a cylinder 3 is fixedly inserted inside the collecting barrel 2, the cylinder 3 opens upward, a water inlet pipe 4 is fixedly installed on one side of the cylinder 3, the water inlet pipe 4 passes through the collecting barrel 2 and the recovery barrel 1 and extends to the outside of the recovery barrel 1, and a drainage pipe 5 is fixedly installed on the outside of the recovery barrel 1.

[0022] When the utility model is used, water is injected into the cylinder 3 through the water inlet pipe 4, and the water fills the inside of the cylinder 3 and the collecting bucket 2. The filtering mechanism can filter the water, and the filtered impurities fall into the inside of the collecting bucket 2 under the action of gravity. The filtered water enters the inside of the recovery bucket 1 and is discharged through the drain pipe 5.

[0023] Specifically, the filtering mechanism includes a filter screen 6, which is movably inserted into the interior of the collection barrel 2, and the filter screen 6 is located above the cylinder 3, and the filter screen 6 is in the shape of a bamboo hat.

[0024] A rotatable shaft 7 is arranged inside the cylinder 3 , the shaft 7 is rotatably connected to the filter screen 6 , and a spiral blade 8 is fixedly sleeved on the outer surface of the shaft 7 .

[0025] A motor 9 is fixedly installed below the recycling barrel 1 , and an output end of the motor 9 passes through the recycling barrel 1 and extends to the inside of the cylinder 3 . The output end of the motor 9 is fixedly connected to one end of the rotating shaft 7 .

[0026] When the utility model is used, when water passes through the filter screen 6, the filter screen 6 can block impurities in the water, so that the impurities can remain in the inside of the collection barrel 2. Since the filter screen 6 is inclined, the impurities on the surface of the filter screen 6 can slide along the surface of the filter screen 6 to the inside of the collection barrel 2, so that the impurities will not gather inside the cylinder 3, and the impurities can be prevented from clogging the cylinder 3.

[0027] At the same time, the motor 9 is connected to an external power source, and the motor 9 drives the rotating shaft 7 to rotate, thereby driving the spiral blades 8 to rotate inside the cylinder 3, accelerating the flow of water from bottom to top inside the cylinder 3, which is beneficial to improving the filtering effect of water.

[0028] Furthermore, a brush 10 is disposed on the outer fixed sleeve of the rotating shaft 7 . The brush 10 is inclined, and the brush 10 is in contact with the lower end surface of the filter screen 6 .

[0029] A protrusion 11 is fixedly installed at one end of the brush 10 away from the rotating shaft 7, and a protrusion 12 is evenly fixedly installed at the lower end of the filter 6. The protrusion 11 and the protrusion 12 are in contact and fit with each other, and there is a gap between two adjacent groups of protrusions 12. The filter 6 is connected to the collection barrel 2 through an elastic structure.

[0030] A protrusion 11 is fixedly installed at one end of the brush 10 away from the rotating shaft 7, and a protrusion 12 is evenly fixedly installed at the lower end of the filter 6. The protrusion 11 and the protrusion 12 are in contact and fit with each other, and there is a gap between two adjacent groups of protrusions 12. The filter 6 is connected to the collection barrel 2 through an elastic structure.

[0031] When the utility model is in use, the rotating shaft 7 drives the brush 10 to move synchronously, and the brush 10 can clean the surface of the filter screen 6. At the same time, the protrusion 11 contacts the protrusion 12, and the protrusion 11 pushes the filter screen 6 to move upward inside the collection barrel 2 through the protrusion 12, thereby driving the slide bar 13 to move synchronously, and the spring 14 is deformed by the force. When the protrusion 11 is not in contact with the protrusion 12, under the elastic force of the spring 14, the spring 14 pushes the filter screen 6 to move downward, and shakes off the impurities attached to the surface of the filter screen 6.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
