[0026] The lifting assembly 49 further includes: Two second levers 494 are rotatably connected to the fixed column 493, and a coil spring is provided at the connection point for flipping the second levers 494; The bottom of the interference rod 495 interferes with one end of the second lever 494 to deflect the second lever 494; The connecting rod 498 is movably connected to the separation cylinder 51 and connected to the bottom of the fixed column 493; A torsion spring 497 is sleeved on the outer wall of the connecting rod 498, and the two ends of the torsion spring 497 are respectively connected to the connecting rod 498 and the bottom of the separation cylinder 51, for resetting the connecting rod 498; A plurality of toggle rods 499 are fixedly connected to the outer wall of the sealing sleeve 492 and move along with the sealing sleeve 492 .

[0027] The inner wall of the separation cylinder 51 is provided with a scraping mechanism 6 for scraping off the feed residue attached to the inner wall of the separation cylinder 51. The scraping mechanism 6 comprises: The annular slide rail 61 is fixedly connected to the bottom of the fixing frame 41; The brush rod 62 is slidably connected to the slide groove provided on the annular slide rail 61 and is attached to the inner wall of the separation cylinder 51. The bottom of the brush rod 62 contacts the flipped second lever 494 and is used to drive the second lever 494 to rotate. Two fixing plates 1 32 are fixedly connected to the outer wall of the cover 3, and two fixing plates 2 34 are fixedly connected to the outer wall of the treatment cylinder 1. The tops of the two fixing plates 2 34 are fixedly connected to multi-stage push rods 33, and the top output ends of the multi-stage push rods 33 are connected to the bottom of the fixing plate 1 32. Above the lid 3, a feed valve 31 is installed for injecting feed sewage residue into the interior of the treatment cylinder 1.

[0028] Working principle: When treating feed sewage residue, first close the discharge valve 55 and the liquid valve 56, and add a phosphorus remover into the interior of the treatment cylinder 1. Then, drive the lid 3 to move downward and seal the treatment cylinder 1 by pushing the multi-stage electric push rod 33. At this time, open the feed valve 31 to inject sewage containing feed residue into the separation cylinder 51 in the treatment cylinder 1. After injecting an appropriate amount, close the feed valve 31; To enable the phosphorus remover and the feed sewage residue to react fully, start the motor 54 and rotate it at a low speed. At this time, the fixed sleeve 52 will be driven to rotate through the gearbox 53, thereby driving the separation cylinder 51 to rotate continuously, and then driving the feed sewage residue inside the separation cylinder 51 to rotate. At the same time, since the fixed frame 41 cannot rotate, the fixed rod 43 and the first shifting rod 44 cannot rotate. Furthermore, when the feed sewage residue rotates with the separation cylinder 51, it can be shifted by the first shifting rod 44, thus realizing the promotion of mixing. At the same time, it can also prevent the residue in the feed sewage from settling to the bottom and promote the reaction with the phosphorus remover; Furthermore, when the separation cylinder 51 rotates, it will also drive the fixed column 493 to rotate, thereby driving the contact rod 495 and the contact hemisphere 496 to rotate, and continuously contacting the wavy sleeve 491 with the contact hemisphere 496. When contacting the peaks and valleys of the wavy sleeve 491, at the peak, it can push the wavy sleeve 491 and the fixed rod 43 upward, and push the spring 46 to be compressed in the connecting sleeve 42 through the sliding sleeve 431. At the same time, at the valley, the spring 46 pushes the sliding sleeve 431 downward and pushes the fixed rod 43 and the wavy sleeve 491 downward. Through the continuous up and down movement of the fixed rod 43, it can drive multiple first shifting rods 41 to move up and down, further improving the shifting effect on the feed sewage residue. At the same time, through the up and down movement of the wavy sleeve 491, it can also drive the sealing sleeve 492 to move up and down, and drive multiple shifting rods 499 to move up and down, which can roll the feed sewage residue that has settled to the bottom and prevent the feed sewage residue from settling to the bottom; Furthermore, when solid-liquid separation is required, the liquid that has passed through the separation cylinder 51 can be discharged by opening the liquid valve 56. After the discharge is completed, the motor 54 is turned on and rotated rapidly, and the fixed sleeve 52 is driven to rotate through the gear box 53, and then the separation cylinder 51 is driven to rotate, and the remaining water is thrown out of the separation cylinder 51 by centrifugal force. At the same time, by rotating the screw 45, the screw 45 will drive the connecting sleeve 42 to move upward, thereby synchronously driving the fixed frame 41 and the fixed rod 43 to move upward, and causing the wavy sleeve 491 to disengage from the interference hemisphere 496, and synchronously driving the sealing sleeve 492 to move upward and separate from the fixed sleeve 52, so that the separated solids can enter the fixed sleeve 52 for discharge. At the same time, when the wavy sleeve 491 moves upward, it contacts the interference hemisphere 496. At this time, under the action of the coil spring, the two levers 494 are toggled to the left and right. The second shift rod 494 rotates and pushes the resistance rod 495 and the resistance hemisphere 496 to move upward for a distance, and the two shift rods 494 open. At the same time, the brush rod 62 located on the annular slide rail 61 can shift the feed residue on the inner wall of the separation cylinder 51 when it moves relative to the separation cylinder 51 to prevent the feed residue from clogging the separation cylinder. At the same time, when the separation cylinder 51 drives the second shift rod 494 to move relative to the brush rod 62 and generates friction, it will push the brush rod 62 to rotate to shift the feed residue that has been centrifugally settled to the bottom to prevent the feed residue from forming a block. At the same time, after the second shift rod 494 is separated from the contact with the brush rod 62, it is reset under the action of the torsion spring 497 to achieve deflection and promote the shifting of the feed residue. After the separation is completed, the speed of the motor 54 is reduced, and the feed residue is brushed downward by the brush rod 62, enters the bottom of the separation cylinder 51, and enters the fixed sleeve 52, and is discharged outward by opening the discharge valve 55. Furthermore, in order to avoid clogging of the separation cylinder 51, during the separation stage, water is intermittently injected through the water inlet conduit 47 and sprayed out through the one-way valve on the fixed rod 43 and the shift rod 44, thereby spraying the rotating separation cylinder 51 to clean the clogged inner wall and further improve the cleaning effect.

[0029] The present invention provides a feed wastewater residue treatment device. There are many methods and approaches to implement this technical solution. The above is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention. Such improvements and modifications should also be considered within the scope of protection of the present invention. Any components not specified in this embodiment can be implemented using existing technologies.
