Rollers 324 are rotatably provided at both ends of the bottom of the base 321 , and an annular slide rail cooperating with the roller 324 is provided on the top of the partition plate.

[0049] Working principle: When in use, the washed metaphosphate is introduced into the inner barrel 32 through the feed hopper 33, and the airflow generator 2 is started, so that the airflow enters the cylindrical sealing box 341, and then pushes the C-shaped plate 343 to move, and then the airflow flows into the air pipe from the air outlet, and then enters the inner barrel 32 through the annular air collecting groove and the air inlet 322 to contact the metaphosphate;

[0050] When the C-shaped plate 343 moves, the rotating shaft 342 is driven to rotate, and the inner barrel 32 is driven to rotate. At this time, the metaphosphate in the inner barrel 32 is dehydrated under the action of centrifugal force, and the water stains separated from the metaphosphate are thrown out from the through hole and fall on the annular guide plate 373, and then fall into the collection box 4 from the outlet;

[0051] In the process of the inner barrel 32 rotating, the gear 355 is driven to rotate by the plurality of tooth blocks 356, and then the cam 354 is driven to rotate, and then the strip collecting plate 352 and the triangular collecting plate 351 are driven to move left and right in the inner barrel 32 by the push plate 353, so as to scrape off the metaphosphate accumulated on the inner wall of the inner barrel 32, increase the contact surface between the metaphosphate and the inner barrel 32, facilitate the metaphosphate in the inner barrel 32 to contact with the airflow, and facilitate the dehydration of the metaphosphate;

[0052] In the process of the inner barrel 32 rotating, the push rod 3574 is driven to rotate, so that the push plate 374 at the bottom of the push rod 3574 rotates on the upper part of the annular guide plate 373, and then the push rod 3574 moves up and down along the annular guide plate 373 during the rotation process;

[0053] When the push rod 3574 moves to the right side of the annular guide plate 373, the push rod 3574 squeezes the second return spring and moves upward, so that the push rod 3574 contacts the cushion block 3573, thereby driving the slide plate 3572 to move upward, thereby driving the guide rod 3576 to squeeze the third return spring to move upward, thereby driving the slide rod 357 to squeeze the first return spring to move upward, so that the multiple block-shaped collecting plates 3571 move upward;

[0054] When the push rod 3574 moves to the left side of the annular guide plate 373, the second return spring drives the push rod 3574 to return to its original position, and the first return spring and the third return spring drive the slide bar 357 and the slide plate 3572 to return to their original position, respectively, so that the block collecting plate 3571 moves up and down while moving left and right, further increasing the contact surface between the metaphosphate and the inner barrel 32, making it easier for the metaphosphate in the inner barrel 32 to be dehydrated and for the metaphosphate in the inner barrel 32 to be in contact with the airflow;

[0055] After a period of time, the collection box 4 containing water is replaced with a new collection box 4 without water. Further, the infrared transmitter 367 is controlled to light up. With the rotation of the inner barrel 32, when the infrared transmitter 367 is aligned with the infrared receiver 312, the infrared receiver 312 supplies power to the single-chip microcomputer, and then the single-chip microcomputer controls the electromagnet 365 to be energized, and then the electromagnet 365 attracts the iron core 366 to stretch the fifth reset spring, so that the T-shaped slide 363 slides, and then drives the second block 362 to engage with the first block 361, so that the discharge baffle 36 is connected with the ejector rod 3574. When the ejector rod 3574 moves up and down, it drives the discharge baffle 36 to move up and down, so that the dry metaphosphate in the inner barrel 32 falls into the annular guide plate 373, and the metaphosphate on the annular guide plate 373 is collected by the push plate 374, so that the metaphosphate falls into the collection box 4 from the outlet.

[0056] The pushing plate 374 will also collect water stains on the annular guide plate 373 during the movement, so as to facilitate the removal of the water stains on the annular guide plate 373 .

[0057] 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.
