Thus, the first scraper 403 rotates with the rotation of the first spiral blade 402, so that the activated carbon remaining on the inner wall of the first extrusion pipe 401 can be scraped off to avoid waste of activated carbon; the second scraper 503 rotates with the rotation of the second spiral blade 502, so that the activated carbon remaining on the inner wall of the second extrusion pipe 501 can be scraped off to avoid waste of activated carbon; the third scraper 701 rotates with the rotation of the rotating rod 802, so that the activated carbon remaining on the inner wall of the transition section extrusion pipe 7 can be scraped off to avoid waste of activated carbon; the rotating rod 802 is driven to rotate by the first driving piece 801, so that the first spiral blade 402 and the second spiral blade 502 rotate, so that the mixed activated carbon is conveyed from the first extrusion pipe 401 to the second extrusion pipe 501 through the rotating first spiral blade 402, and the first extrusion treatment is performed at the connection between the first extrusion pipe 401 and the second extrusion pipe 501, then the activated carbon is conveyed from the second extrusion pipe 501 to the screen 6 position through the rotating second spiral blade 502, and the second extrusion treatment is performed at the screen 6 position, and finally the activated carbon is extruded into granular form through the screen 6.

[0052] Specifically, the screen 6 is installed on the side of the second extrusion pipe 501 away from the first extrusion pipe 401 by bolts, and the screen 6 can be quickly installed and removed by bolts, so that different models of screens 6 (i.e., screens 6 with different particle sizes) can be replaced according to different pretreatment requirements of the activated carbon (i.e., the particle size of the final granular activated carbon).

[0053] For example, the first driving member 801 is an electric motor.

[0054] In this embodiment, the mixing mechanism 2 includes a mixing box 201, two feed ports 202, a discharge port 203, a second driving member 205, and a mixing stirring rod 206. The mixing box 201 is installed at the bottom of the grinding mechanism 1, and the powdered activated carbon ground by the grinding mechanism 1 enters the mixing box 201. The two feed ports 202 are respectively located on the two sides of the mixing box 201, and are respectively used to inject water and a binder into the mixing box 201.

Thus, the second driving member 205 is started, and the rotation of the mixing stirring rod 206 is driven by the second driving member 205 to uniformly mix the powdered activated carbon, water, and binder, so as to facilitate the subsequent extrusion molding of the activated carbon and the pretreatment of the activated carbon into granular activated carbon, and facilitate the subsequent high-temperature activation regeneration.

[0055] For example, the second driving member 205 is an electric motor.

[0056] In this embodiment, two grinding mechanisms 1 are provided, and the two grinding mechanisms 1 are respectively located on the two sides of the second driving member 205.

Specifically, the grinding mechanism 1 includes a grinding box 101, two grinding rollers 102, and two fourth driving members 103. The two grinding rollers 102 abut each other, and the two fourth driving rollers are respectively used to drive the rotation of the two grinding rollers 102. The honeycomb or columnar activated carbon is ground by the two rotating grinding rollers 102 to become powdered activated carbon.

[0059] Specifically, the frequency of the cutting blade 902 moving downward is controlled by controlling the start-stop frequency of the third driving member 901, so that the pretreatment requirements of different activated carbons can be met (that is, the higher the frequency of the cutting blade 902 moving downward, the higher the cutting frequency of the cutting blade 902 on the extruded activated carbon, and the smaller the particle size of the granular activated carbon, and vice versa, the larger the particle size of the granular activated carbon).

[0060] For example, the third driving member 901 is a pneumatic cylinder.

[0062] It should be noted that the extruding mechanism 3 is supported by the rack 11.

[0063] The pretreatment process of the honeycomb or columnar activated carbon is as follows: firstly, according to the requirements of activated carbon regeneration pretreatment, a screen 6 matched with the requirements is selected for use, and the start-stop frequency of the third driving part 901 is set; then, the honeycomb or columnar activated carbon is added into the grinding mechanism 1, and the grinding mechanism 1 is started to grind the honeycomb or columnar activated carbon into powder, and the powder-like activated carbon flows into the mixing box 201; then, water and a binder are added into the mixing box 201 through two feeding ports 202 respectively, and the second driving part 205 is started to drive the mixing stirrer 206 to rotate, so as to mix the powder-like activated carbon, water and the binder, and then the valve 204 is opened to make the mixed activated carbon flow into the first extrusion pipe 401 through the discharge port 203; then, the first driving part 801 is started to drive the rotating rod 802 to rotate, so that the first spiral blade 402 and the second spiral blade 502 rotate, the mixed activated carbon is gradually extruded from the first extrusion pipe 401 into the second extrusion pipe 501 through the rotating first spiral blade 402, and the mixed activated carbon is gradually extruded from the second extrusion pipe 501 to the screen 6 through the rotating second spiral blade 502; in addition, under the rotation of the rotating rod 802, the first scraper 403, the second scraper 503 and the third scraper 701 rotate to scrape off the activated carbon remaining on the inner walls of the first extrusion pipe 401, the second extrusion pipe 501 and the transition section extrusion pipe 7; finally, the third driving part 901 is started to drive the cutting blade 902 to move downward to cut the activated carbon extruded out through the screen 6, so as to cut the activated carbon into granular activated carbon.

[0064] In summary, the first extrusion part 4 and the second extrusion part 5 are used to press the mixed activated carbon twice, compared with the existing extrusion mode relying on the cooperation of the spiral blade and the screen 6, the mode has the advantages of simple structure and convenient operation, and the twice extrusion can improve the extrusion effect and efficiency of the activated carbon, thereby improving the pretreatment effect and efficiency of the activated carbon.
