[0002] Activated alumina is a porous, highly dispersed solid material with a large surface area. Its microporous surface has the characteristics required for catalysis, such as adsorption performance, surface activity, excellent thermal stability, etc., so it is widely used as a catalyst and catalyst carrier for chemical reactions.

[0003] The oil absorption value and viscosity of activated alumina are its important physical properties, and one of the reasons why it is widely used in industry. Viscosity is the flow property of alumina, and its size is related to factors such as the surface properties and particle size of the activated alumina.

[0027] The cleaning part 210 includes a plurality of cleaning plates 211 movably arranged inside the screening box 130, each cleaning plate 211 is fixed with a soft cleaning brush 212, the soft cleaning brush 212 is in contact with the inner bottom end surface of the screening box 130, both ends of the cleaning plate 211 are fixed with elastic scrapers 213, the elastic scrapers 213 are slidably connected with the inner wall of the screening box 130, and the design of the elastic scrapers 213 is to scrape off the active alumina around the screening box 130, and the cleaning plate 211 is provided with a driving member 214. The driving member 214 is a motor, the output shaft of the motor is fixedly connected with the top center of the cleaning plate 211, and the motor is fixed on the adjusting part 220.

[0028] Specifically, the adjusting part 220 includes a connecting plate 221 movably arranged inside the screening box 130 and a power member 222 for adjusting the height of the connecting plate 221. The driving member 214 is fixed on the connecting plate 221. The connecting plate 221 supports the driving member 214. On the other hand, it is also a bridge connecting the power member 222 and the cleaning part 210. One end of the connecting plate 221 extends through the screening box 130 to the outside and is fixedly connected to the power member 222.

[0029] Specifically, the number of the cleaning plates 211 and the screening boxes 130 corresponds one to one, and the distances from the bottom ends of the cleaning plates 211 to the bottom ends of the inner walls of the corresponding screening boxes 130 are equal. Each screening box 130 has a corresponding cleaning plate 211 inside.

[0030] Specifically, a plurality of the screening boxes 130 have a receiving opening 510 at the position corresponding to the connecting plate 221, and two sides of the receiving opening 510 are provided with through openings 500, and one end of the connecting plate 221 is moved through the through openings 500 and the receiving opening 510 in sequence and then extends to the outside, and an elastic pleated cloth 400 is sealed and fixed around the inner wall of the receiving opening 510, and a cloth opening 410 is provided on the elastic pleated cloth 400, and the outer surface of the connecting plate 221 and the inner surface of the cloth opening 410 are sealed and fixedly connected.

[0033] A power source 2224 is fixed to one end of the lead screw 2223. The power source 2224 is a reciprocating motor, and the output shaft of the reciprocating motor is fixedly connected to one end of the lead screw 2223. The reciprocating motor can drive the lead screw 2223 to reciprocate, thereby driving the T-shaped driving plate 2222 to move up and down, so as to achieve the purpose of adjusting the height of the connecting plate 221 and the cleaning part 210. When it is necessary to clean the activated alumina clogged on the screen, the height of the cleaning part 210 can be lowered, so that the soft cleaning brush 212 can clean the inner bottom end of the screening box 130.

A support leg is fixed to the bottom end of the bottom plate 330, and an elastic spring 320 is fixed between the bottom plate 330 and the arc-shaped connecting block 310.

[0036] When the multi-layer screening device for processing activated alumina of the embodiment of the present application is actually used, the vibrator 110 is first started, and then the activated alumina is added to the screening box 130. Under the action of the vibrator 110, the screening box 130 screens the activated alumina, and the screened activated alumina is discharged from the discharge pipe 120. When the screen on the screening box 130 is blocked, the reciprocating motor of the power source 2224 is started, and the reciprocating motor drives the lead screw 2223 to rotate, and the T-shaped driving plate 2222 moves downward. The connecting plate 221 is synchronously driven to move downward. When the soft cleaning brush 212 contacts the bottom end surface of the screening box 130, the reciprocating motor stops and the driving member 214 is started. The driving member 214 drives the cleaning plate 211 to rotate. The cleaning plate 211 drives the soft cleaning brush 212 to clean the screen on the screening box 130. The elastic scraper 213 on the cleaning plate 211 scrapes off the active alumina remaining on the inner periphery of the screening box 130. The inner bottom end surface of the last layer of the screening box 130 is cleaned.

[0037] After cleaning, the reciprocating motor of the power source 2224 is used again. The reciprocating motor drives the lead screw 2223 to rotate in the opposite direction, and the T-shaped driving plate 2222 moves upward, synchronously driving the connecting plate 221 and the cleaning part 210 to move upward, and the soft cleaning brush 212 leaves the inner bottom end of the screening box 130, which does not affect the subsequent screening operation of the activated alumina. The through port 500 provides a moving space for the connecting plate 221, and the elastic pleated cloth 400 prevents the activated alumina from flying out of the through port 500 and the accommodating port 510.
