Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The present invention provides a transmission high-efficiency thickener automatic dilution device, comprising a thickener pool 1, a transmission mechanism 2 for cleaning upper liquid foam is arranged on the thickener pool 1, and a feeding mechanism 3 for automatically feeding additives in cooperation with the transmission mechanism 2 is arranged on the thickener pool 1; the transmission mechanism 2 comprises a stirring shaft 24 arranged to rotate inside the thickener pool 1, and a stirring blade 23 for stirring the bottom liquid of the thickener pool 1 is arranged on the bottom surface of the stirring shaft 24; the transmission mechanism 2 also comprises a crossbeam 21 erected on the thickener pool 1, and a first slide 26 is installed on the crossbeam 21 to slide along the crossbeam 21 when the stirring shaft 24 rotates, and a buoyancy plate 28 that moves according to the buoyancy of the liquid slides at the bottom of the first slide 26, and scraping plates 27 with a telescopic function are installed on both sides of the buoyancy plate 28; while the stirring shaft 24 drives the stirring blade 23 to stir the liquid at the bottom of the thickener pool 1, the stirring shaft 24 drives the first slide 26 to move on the crossbeam 21, and at this time the buoyancy plate 28 is on the surface of the upper liquid layer due to the buoyancy of the liquid. When the first slide 26 moves, the buoyancy plate 28 is driven to move on the surface of the upper liquid layer to process the foam on the surface of the upper liquid layer. A motor 22 for driving the stirring shaft 24 to rotate is arranged at the bottom of the thickener tank 1. The output end of the motor 22 is fixedly connected to the stirring shaft 24. The crossbeam 21 is fixedly mounted on the top of the thickener tank 1, and a slide groove for the first slide 26 and the second slide 34 to slide is arranged on the crossbeam 21. A screw rod 25 rotates inside the crossbeam 21. The outer thread of the screw rod 25 is connected to the bearing seat on the first slide 26 through a ball nut pair. The screw rod 25 and one end of the stirring shaft 24 are both installed with a bevel gear, and the two bevel gears are meshed and connected. A vertical shaft 29 is installed at the bottom of the first slide 26. The buoyancy plate 28 slides along the vertical shaft 29. The buoyancy plate 28, the scraper plate 27 and the vertical shaft 29 are two groups, and are respectively installed on the first slide 26 and the second slide 34. See also Figures 1 to 7As shown, the motor 22 is started, and the output end of the motor 22 drives the stirring shaft 24 to rotate, and the stirring shaft 24 drives the stirring blades 23 to rotate. The stirring blades 23 stir the liquid inside the thickener pool 1, which can improve the dilution efficiency of the liquid inside the thickener pool 1; while the stirring shaft 24 rotates, since the bevel gear at one end of the stirring shaft 24 is meshed with the bevel gear on the screw rod 25, the screw rod 25 is driven to rotate while the stirring shaft 24 rotates, and because the outer thread of the screw rod 25 is connected to the bearing seat on the first slide 26 through a ball nut pair, when the screw rod 25 rotates, the first slide 26 moves along the screw rod 25 on the crossbeam 21, and at the same time, the first slide 26 drives the vertical shaft 29 at the bottom to move.

During the rotation of the stirring shaft 24, the additive inside the discharge pipe 37 is continuously delivered to the inside of the thickener tank 1 through the discharge port, and the stirring of the stirring blade 23 can make the additive added more evenly; by cooperating with the first slide 26 to move and clean the foam of the upper layer of liquid, the discharge pipe 37 automatically delivers and adds to the middle and lower layers of liquid, thereby simultaneously processing multiple layers of liquid, further improving the dilution efficiency of the thickener tank 1 for the liquid; In addition, according to the actual situation, the storage capacity of the additive inside the piston cylinder 32 is set, which can automatically add a certain amount of additive to the thickener tank 1 to avoid large errors in manual addition and affect the dilution of the liquid inside the thickener tank 1; at the same time, with the reciprocating movement of the first slide 26, the effect of timely, quantitative and automatic addition of additives can be achieved, further reducing the workload of the staff and improving the dilution efficiency.

[0023] In addition, during the movement of the second slide 34, the second slide 34 also drives the buoyancy plate 28 to move through the vertical axis 29. The buoyancy plate 28 is located on the surface of the upper liquid due to the buoyancy of the liquid. The buoyancy plate 28 moves on the surface of the upper liquid while driving the scraper plate 27 to move. The scraper plate 27 can puncture and scrape the foam generated on the surface of the upper liquid, thereby processing multiple surfaces of the upper liquid inside the thickener tank 1, further improving its dilution efficiency.

[0024] A method for automatic dilution of a transmission high-efficiency thickener, using the above-mentioned automatic dilution device of a transmission high-efficiency thickener, comprises the following steps: Step 1: The pre-mixed additives in the stirring box 31 are added into the piston cylinder 32, and the stirring shaft 24 drives the stirring blades 23 to continuously stir the liquid at the bottom of the thickener tank 1; Step 2: The first slide 26 moves along the cross beam 21, and the first slide 26 and the second slide 34 simultaneously drive the buoyancy plate 28 to move, so as to process the foam on the surface of the upper liquid; Step 3: The second slide seat 34 moves while squeezing the additive inside the piston cylinder 32 and delivering it into the inside of the discharge pipe 37; Step 4: The additive inside the discharge pipe 37 is automatically discharged into the thickener tank 1 through the discharge port.

When the scraper plate 27 moves to the inner edge of the thickener pool 1, one end of the scraper plate 27 will contact the inner wall of the thickener pool 1, and will be squeezed by the inner wall of the thickener pool 1, so that the scraper plate 27 can shrink, thereby increasing the cleaning area of ​​the scraper plate 27 and improving its working flexibility. In addition, a telescopic spring is arranged inside the scraper plate 27, which can be expanded and reset by elastic force when the scraper plate 27 is no longer squeezed by the inner wall of the thickener pool 1.

[0026] While the first slide 26 moves to treat the foam on the surface of the upper liquid, the stirring box 31 dilutes and pre-treats the additive inside; most flocculants need to be dissolved before adding and activated before use, which is usually done by dissolving the solid flocculant in water and stirring it for a certain period of time to fully dissolve and activate it, ensuring that it can effectively react with the solid particles in the suspension and transport the diluted pre-treated additive to the inside of the piston cylinder 32 through the first connecting pipe 33.
