The workers will increase the complexity of waterproofing the separation installation tank 101, and a large amount of solvent in the soaking water will be discharged before participating in the paper-plastic separation, which will directly affect the water quality, thereby forming a restriction and improving the operation standardization of the workers. In the normal paper-plastic separation work, the crushed paper-plastic raw material is put into the through holes on the rotary material storage block 301 through a conveyor belt or manual feeding. At this time, the electromagnetic valve of the installation pipe 103 connected to the water source needs to be opened to supply water, and the water source needs to be added with a solvent in advance. Acidic solvents such as acetic acid can neutralize alkaline adhesives and promote separation and soaking effect. At this time, as the liquid level rises, the liquid surface buoyancy pushes the lifting ring 403 to move upwards, driving the sliding shaft 402 to press the liquid level switch 404.

[0039] The working principle of the present embodiment is as follows: first, place the separation installation tank 101 on the ground, and put the crushed paper-plastic raw materials into the through holes on the rotary material storage block 301 through a conveyor belt or manually. At this time, the electromagnetic valve of the installation pipe 103 connected to the water source needs to be opened to supply water. The solvent, such as acetic acid, is added in advance to neutralize the alkaline adhesive and promote the separation and soaking effect. At this time, as the liquid level rises, the liquid surface buoyancy pushes the lifting ring 403 to move upwards, driving the sliding shaft 402 to press the liquid level switch 404. At this time, the liquid level switch 404 can control the magnetic attraction of the rack 202, lengthening the tension spring 203, and the rack 202 can quickly engage the gear 302 to drive the rotary material storage block 301 to rotate. The through holes on the two feeding baffles 201 are misaligned, and at this time the raw materials in the through holes on the rotary material storage block 301 will be discharged from the two through holes on the bottom feeding baffle 201, achieving the placement on the soaking water surface. After the rotary material storage block 301 rotates to discharge the paper-plastic raw materials, the upper feeding baffle 201 can be attached to assist in closing, and then the stirring motor 501 drives the stirring teeth 502 to mix and stir to promote the separation of plastic from the paper-plastic raw materials. The paper fibers can pass through the isolation plate 6011 for subsequent independent discharge. The stirring motor 501 drives the stirring teeth 502 to stir the raw materials and soaking water. At this time, the paper-plastic raw material debris in the separation installation tank 101 will rotate to generate a vortex. The negative pressure suction pump 106 performs real-time suction to assist in generating negative pressure, promoting the penetration of soaking water into the paper-plastic raw material debris. At the same time, the electric heating wire provided in the separation installation tank 101 is heated in real time. When checking the separation effect of the paper-plastic raw materials, the opening of the rotating sampling groove 1021 can be directed against the stirring rotation direction of the raw materials. The through groove on the sampling groove 1021 can be used to filter the paper-plastic raw material debris, and then the sampling shaft 102 is pulled out, but not completely. At this time, whether there are still a large number of paper fibers attached to the plastic pieces on the sampling groove 1021 can be observed. First, open the electromagnetic valve on the lower part of the fiber discharge pipe 104, and the electromagnetic valve on the upper part of the fiber discharge pipe 104 is always open to discharge the soaking water containing paper fibers. As the water level drops, the buoyancy support float block 703 no longer supports the counterweight ring 702 when the water level is lower than the buoyancy support float block 703. At this time, the support counterweight ring 702 falls under the action of gravity, driving the flow switch 704 to press the bottom of the separation installation tank 101. At this time, the flow switch 704 controls the electromagnetic valve on the upper part of the fiber discharge pipe 104 to close and the electromagnetic valve on the upper discharge pipe 105 to open, realizing the discharge of the upper layer soaking water, that is, the tail section soaking water, for independent collection. During the process, the electromagnetic valve on the lower part of the fiber discharge pipe 104 is closed.The scraper 503 is driven to rotate by the stirring motor 501 to scrape the isolation plate 6011, so as to promote the plastic raw materials on the isolation plate 6011 to gather at the bottom of the isolation plate 6011, and the plastic raw materials can be quickly discharged after the rotating dismounting plug 602 is removed. In the process, the electromagnetic valve on the installation pipe 103 of the external fan can be opened to supply air and assist the quick discharge of the plastic raw materials. When paper-plastic separation is performed next time, the soaking water can be continuously added in the separation installation tank 101 for separation and soaking. The electromagnetic valve on the upper discharge pipe 105 can be temporarily controlled to be closed by the switch connected to the electromagnetic valve. After the water level is higher than the buoyant block 703, the shunt switch 704 is no longer pressed. At this time, the shunt switch 704 can control the electromagnetic valve on the upper fiber discharge pipe 104 to be opened and the electromagnetic valve on the upper discharge pipe 105 to be closed. After the paper fiber mixed liquid is discharged, the liquid level is lowered, the lifting ring 403 is lowered, the liquid level switch 404 is no longer pressed, the electromagnetic iron 204 is controlled to be powered off, the rotary storage block 301 is quickly rotated and reset under the pulling of the tension spring 203, the paper-plastic raw materials are conveniently pre-filled again, the electromagnetic valve of the installation pipe 103 connected to the water source is controlled to be opened to supply water, the liquid level is raised again, the liquid level switch 404 is pressed again by the buoyancy, and the control of the discharge work is realized.
