[0040] When producing acetate, first put an appropriate amount of water into the mixing tank 2, and then add acetic acid. During production, certain impurities may be generated at this time. To ensure the concentration of acetate, it is necessary to filter the liquid. Drive the first motor, which then drives the second bidirectional lead screw 451 to rotate, which then drives the second threaded seat 452 to move, which then drives the connecting plate 46 to move, which then drives the connecting strip to move, which then drives the strip-shaped seat 44 to move, which then drives the filter plate 43 to move. Through the movement of the filter plate 43, filtration is achieved. At the same time, the second bidirectional lead screw 451 drives the sliding rod 456 to rotate, which then drives the first bevel gear 459 to rotate, which then drives the second bevel gear 465 to rotate, which then drives the second rotating rod 462 to rotate, which then drives the first rotating rod 461 to rotate, which then drives the first belt pulley 441 to rotate, which then drives the second belt pulley 442 to rotate through the belt 443, which then drives the filter plate 43. Through the rotation of the filter plate 43, the liquid is stirred, agitating the liquid, so as to achieve filtration in a larger range.

[0041] At the top end of the surface of the sliding rod 456, a first turntable 457 is fixedly arranged. On the surface of the first turntable 457, a first slider 458 is rotatably arranged. One side of the first slider 458 is connected to one side of the connecting plate 46 through a second connecting block 460.

[0042] By setting the first turntable 457, the first slider 458 and the second connecting block 460, when the connecting plate 46 moves up and down, it can drive the sliding rod 456 to move up and down simultaneously, achieving the effect of synchronous movement.

On the other side at the bottom end of the first connecting block 445, a vertical rod 446 is fixedly arranged. At the bottom of the vertical rod 446, a limiting toothed plate 447 is fixedly arranged. On the outer side of the first rotating rod 461, a limiting gear 463 that cooperates with the limiting toothed plate 447 is fixedly arranged.

[0044] When the filter plate 43 does not need to rotate, at this time, drive the fourth electric telescopic rod 468 to work, thereby driving the third connecting block 467 to move, thereby driving the second slider 466 to move, thereby driving the second turntable 464 to move, thereby driving the second rotating rod 462 to move, thereby driving the second bevel gear 465 to move, so that the second bevel gear 465 is separated from the first bevel gear 459. Thus, at this time, the filter plate 43 will not be driven to rotate. At the same time, drive the third electric telescopic rod 444, thereby driving the first connecting block 445 and the vertical rod 446 to move, thereby driving the limiting toothed plate 447 to move downward, so that the limiting toothed plate 447 meshes with the limiting gear 463, thereby realizing the limitation of the first rotating rod 461, and thus realizing the limitation of the filter plate 43 to prevent it from rotating.

[0045] The filter plate 43 is specifically two U-shaped plates 431 arranged oppositely. On the inner sides of the two U-shaped plates 431, filter meshes 432 are arranged.

A second gear 427 is rotatably arranged at the top of the cross plate 426. A tooth groove 450 meshing with the second gear 427 is formed on the surface of the movable disk 45. The second gear 427 is driven by a second motor, and the first bidirectional lead screw 421 is driven by a third motor.

[0047] When the filter plate 43 is in a vertical state, the third motor can be driven at this time, thereby driving the first bidirectional lead screw 421 to rotate, thereby driving the first threaded seat 422 to move, thereby driving the installation post 423 to move, thereby driving the cross bar 425 to move, thereby driving the connecting rod 429 to move, thereby driving the guide ring 428 to move, thereby driving the movable disk 45 to move, and thereby driving the filter plate 43 to move back and forth.

[0048] A vertical plate 411 is fixedly arranged on the left side of the top of the second mounting plate 41. An infrared emitter 424 is fixedly arranged on the left side of the installation post 423. An infrared receiver 412 for cooperating with the infrared emitter 424 is arranged on the right side of the vertical plate 411. A second electric telescopic rod 415 is fixedly arranged on the top of the second mounting plate 41. A strip-shaped block 414 is fixedly arranged on the top of the second electric telescopic rod 415. A baffle 413 is fixedly arranged on the left side of the strip-shaped block 414.

[0049] When the installation post 423 moves, it can drive the infrared emitter 424 to move. When the infrared receiver 412 receives the signal of the infrared emitter 424, the filter plate 43 is at the middle position at this time.

[0050] A trigger block 455 is fixedly arranged on the surface of one of the guide rods 453, and a pressure sensor is arranged on the surface of the trigger block 455.

[0051] A first mounting plate 21 is fixedly arranged at the rear side of the mixing box 2. A bracket 22 is fixedly arranged on the top of the first mounting plate 21.

The output end of the processor is electrically connected to the input end of the relay. The output end of the relay is electrically connected to the third motor, the third electric telescopic rod 444, and the fourth electric telescopic rod 468.

[0053] Working principle: When producing acetate, first put an appropriate amount of water into the mixing tank 2, and then add acetic acid. During production, certain impurities may be generated at this time. To ensure the concentration of acetate, it is necessary to filter the liquid. Drive the first motor, which in turn drives the second bidirectional lead screw 451 to rotate, which in turn drives the second threaded seat 452 to move, which in turn drives the connecting plate 46 to move, which in turn drives the connecting bar to move, which in turn drives the strip seat 44 to move, which in turn drives the filter plate 43 to move. Through the movement of the filter plate 43, filtration is achieved. At the same time, the second bidirectional lead screw 451 drives the slide bar 456 to rotate, which in turn drives the first bevel gear 459 to rotate, which in turn drives the second bevel gear 465 to rotate, which in turn drives the second rotating rod 462 to rotate, which in turn drives the first rotating rod 461 to rotate, which in turn drives the first belt pulley 441 to rotate, and then drives the second belt pulley 442 to rotate through the belt 443, which in turn drives the filter plate 43. Through the rotation of the filter plate 43, the liquid is stirred, agitating the liquid, so as to achieve filtration in a larger range. By setting the first turntable 457, the first slider 458, and the second connecting block 460, when the connecting plate 46 moves up and down, it can drive the slide bar 456 to move up and down at the same time, achieving the effect of synchronous movement; when the filter plate 43 does not need to rotate, at this time, drive the fourth electric telescopic rod 468 to work, which in turn drives the third connecting block 467 to move, which in turn drives the second slider 466 to move, which in turn drives the second turntable 464 to move, which in turn drives the second rotating rod 462 to move, which in turn drives the second bevel gear 465 to move, so that the second bevel gear 465 is separated from the first bevel gear 459. At this time, the filter plate 43 will not be driven to rotate. At the same time, drive the third electric telescopic rod 444, which in turn drives the first connecting block 445 and the vertical rod 446 to move, which in turn drives the limit tooth plate 447 to move downward, so that the limit tooth plate 447 meshes with the limit gear 463, thereby realizing the limitation of the first rotating rod 461, and thus realizing the limitation of the filter plate 43 to prevent it from rotating.
