Description

Technical Field

[0001] This invention relates to the field of activated carbon processing technology, and specifically to a screening device for activated carbon processing. Background Technology

[0002] Activated carbon is a type of carbon that has undergone special treatment and typically possesses strong adsorption capacity, enabling it to adsorb pollutants. It is commonly used for purifying and treating wastewater. Post-production activated carbon is usually of uneven size and mixed together. To improve its effectiveness, it is generally screened. However, current activated carbon screening devices do not achieve thorough screening in practice. The activated carbon is poured onto the screen through the feed pipe and rapidly discharged towards the outlet on the continuously vibrating screen. This often results in some unscreened material being discharged directly, necessitating repeated screening. Furthermore, the activated carbon particles easily clog the screen holes, especially with increasing usage time, leading to a decrease in screening efficiency. Summary of the Invention

Detailed Implementation

[0020] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0021] Example: Reference Figures 1-8 A screening device for activated carbon processing includes a frame 1, on which a screening device is mounted. The screening device includes a screen cylinder 301 and is used to screen activated carbon particles of different sizes. A feeding device is located in front of the screening device, and the feeding device includes a feeding box 201. The feeding device is used to perform preliminary filtration of the activated carbon. An auxiliary device is located above the screening device, and the auxiliary device includes a horizontal plate 401. The horizontal plate 401 is fixedly mounted on the frame 1 and is used to prevent the screening device from becoming clogged.

[0022] The activated carbon raw material is fed from the feeding device to the screening device. In the feeding device, some larger impurities and dust can be initially screened out. The rotating screening device can screen the activated carbon particles into large, medium and small sizes. At the same time, the auxiliary device can clean the activated carbon that is clogging the pores, which can help to screen the activated carbon.

[0023] like Figures 1-6 As shown, the feeding device includes an adjusting rod 202 fixed on the feeding box 201, a spring 205 provided on the adjusting rod 202, a coarse screen 203 slidably mounted on the adjusting rod 202, a rotating shaft 206 rotatably mounted inside the feeding box 201, a cam 207 rotatably mounted on the rotating shaft 206, a rotating pulley I 209 rotatably mounted on the top of the rotating shaft 206, a waste port 208 provided on the side of the feeding box 201, and a motor support frame 204 fixedly mounted on the frame 1.

[0024] Activated carbon raw materials are fed into the inlet of the feeding device. Once inside, the first motor 308 is started, driving the motor shaft 309 to rotate. The rotation of the motor shaft 309 drives the rotating pulley II 307 to rotate. The rotating pulley II 307 drives the rotating pulley I 209 to rotate via the rotating belt 319, thereby rotating the rotating shaft 206. The rotation of the rotating shaft 206 drives the cam 207 to vibrate the coarse screen 203. The coarse screen 203 has arranged holes, which performs preliminary screening of the activated carbon particles entering the feeding device. Larger impurities and some dust are discharged through the waste port 208.

[0025] like Figures 1-3 As shown, the screening device includes a screen cylinder 301 rotatably mounted on a frame 1. The surface of the screen cylinder 301 is provided with a plurality of small holes 304, medium holes 303 and large holes 302 in sequence. A large gear 305 is rotatably mounted on one end of the screen cylinder 301. A first motor 308 is fixedly mounted on the motor support frame 204. A motor shaft 309 is rotatably mounted on the movable end of the first motor 308. A rotating pulley II 307 is rotatably mounted on the motor shaft 309. A rotating belt 319 is wound around the rotating pulley II 307 and the rotating pulley I 209. A small gear 306 is rotatably mounted on the top end of the motor shaft 309. The small gear 306 meshes with the large gear 305.

[0026] When activated carbon enters the screening device 308, it simultaneously drives the small gear 306 to rotate via the motor shaft 309, which in turn drives the large gear 305 to rotate, and the large gear 305 drives the screen cylinder 301 to rotate as a whole.

[0027] like Figures 1-6 As shown, a main shaft 310 is rotatably mounted inside the screen cylinder 301. A feeding blade 314 is provided at the front end of the main shaft 310, and a stirring blade 315 is fixedly mounted at the rear end of the main shaft 310.

[0028] like Figures 1-6As shown, multiple arc frames 311 are fixedly installed on the outer ring of the screen cylinder 301. Arc guide wheels 312 are rotatably installed on the arc frames 311. Semi-arc frames 316 are fixedly installed on the arc guide wheels 312. A material slurry brush 318 is provided on the semi-arc frame 316. The material slurry brush 318 corresponds to the small holes 304, medium holes 303 and large holes 302 in each row. A semi-arc gear 317 is fixedly installed at one end of the semi-arc frame 316. A limit groove is provided on the tail end of the frame body 1.

[0029] like Figure 3 As shown, multiple material dropping limit blocks 320 are fixedly installed inside the frame 1, and the ports of the material dropping limit blocks 320 are aligned with the screen cylinder 301. A material dropping box 313 is provided below the material dropping limit blocks 320 and is placed on the ground.

[0030] Activated carbon is conveyed into the screen cylinder 301 through 314 at the front end of 310. While the screen cylinder 301 rotates as a whole, the stirring blades 315 rotate in the opposite direction, causing the activated carbon to rotate. When the activated carbon rotates, smaller particles fall through 304, and larger particles fall into the medium and large holes at the rear through the rotation, falling into the material limit plate 320 in sequence, and finally falling into the material box 313.

[0031] like Figures 1-8 As shown, the auxiliary device includes a second motor 402 fixedly mounted on a horizontal plate 401. A transmission shaft 404 is rotatably mounted on the movable end of the second motor 402. A transmission pulley I 403 is rotatably mounted on the transmission shaft 404. A rotating shaft 407 and an auxiliary gear 411 are rotatably mounted on the frame 1. A driving gear 408 is rotatably mounted on the rotating shaft 407. A transmission pulley II 406 is rotatably mounted in front of the driving gear 408. A transmission belt 405 is wound around the outside of the transmission pulley I 403 and the transmission pulley II 406. The driving gear 408 meshes internally with the auxiliary gear 411. A driven gear 409 is rotatably mounted on the main shaft 310. The driven gear 409 meshes with the driving gear 408. A toggle gear 410 is rotatably mounted in front of the driven gear 409. A missing gear 412 is fixedly mounted on the auxiliary gear 411. The missing gear 412 meshes with a semi-circular gear 317. The toggle gear 410 meshes with the semi-circular gear 317.

[0032] While 301 rotates, the second motor 402 operates, driving the rotating shaft 407 to rotate. The rotation of the rotating shaft 407 drives the transmission pulley I 403 to rotate, and the transmission pulley I 403 drives the transmission pulley II 406 to rotate via the transmission belt 405, thereby driving the drive gear 408 to rotate. The rotation of the drive gear 408 drives the driven gear 409 to rotate, and the rotation of the driven gear 409 drives the main shaft 310 to rotate, simultaneously driving the shifting gear 410 to rotate. While the drive gear 408 rotates, it also drives the auxiliary gear 411 to rotate, thus enabling the missing gear 412 to drive the semi-circular gear 317 to move forward, and then the shifting gear 410 to drive the semi-circular gear 317 to rotate in reverse, so that the semi-circular frame 316 can rotate back and forth along the limiting slide groove to clear the blockage of the holes in the screen cylinder 301.

[0033] The working principle of the screening device for activated carbon processing disclosed in this invention is as follows: Activated carbon raw material is fed into the inlet of the feeding device. The raw material enters the feeding device, and the first motor 308 is started. The first motor 308 drives the motor shaft 309 to rotate. The rotation of the motor shaft 309 drives the rotating pulley II 307 to rotate. The rotating pulley II 307 drives the rotating pulley I 209 to rotate via the rotating belt 319, thereby realizing the rotation of the rotating shaft 206. The rotation of the rotating shaft 206 drives the cam 207, which can adjust the gap of the coarse screen 203. The activated carbon particles entering the feeding device are initially screened by shaking and the coarse screen 203 has a series of holes. Larger impurities and some dust are discharged through the waste port 208. When the activated carbon enters the screening device 308, the motor shaft 309 drives the small gear 306 to rotate, which in turn drives the large gear 305 to rotate. The large gear 305 drives the entire screen cylinder 301 to rotate. The activated carbon is conveyed into the screen cylinder 301 through the front end 314 of 310. The entire screen cylinder 301 rotates. Simultaneously, the stirring blades 315 rotate in the opposite direction, causing the activated carbon to rotate. As the activated carbon rotates, smaller particles fall through 304, while larger particles fall through the medium and large holes at the rear, sequentially falling into the material discharge limit plate 320 and finally into the material discharge box 313. At the same time, while the screen cylinder 301 rotates, the second motor 402 operates, driving the rotating shaft 407 to rotate. The rotating shaft 407 drives the transmission pulley I 403 to rotate, and the transmission pulley I 403 drives the transmission pulley II via the transmission belt 405. Rotation of gear 406 drives the drive gear 408 to rotate, which in turn drives the driven gear 409 to rotate. The driven gear 409 then drives the main shaft 310 to rotate, which in turn drives the actuating gear 410 to rotate. Simultaneously, the rotation of the drive gear 408 drives the auxiliary gear 411 to rotate. This allows the missing gear 412 to drive the semi-circular gear 317 to rotate forward, while the actuating gear 410 drives the semi-circular gear 317 to rotate in reverse. This enables the semi-circular frame 316 to rotate back and forth along the limiting slide groove, thus clearing blockages in the holes of the screen cylinder 301.

Various modifications and variations can be made to the present invention by those skilled in the art.
