DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-4 A zinc sulfate purification device comprises a reactor 1, an upper pressing plate 16 and a lower pressing plate 6. The reactor 1 is used for reacting a zinc sulfate solution and zinc powder. When in use, the zinc sulfate solution and zinc powder are put into the reactor 1 for reaction.

[0027] The upper pressure plate 16 is horizontally arranged inside the reactor 1 and is slidably sealed with the inner wall of the reactor 1. The upper pressure plate 16 is circular in design and fits with the inner wall of the reactor 1. A rubber ring is provided at the connection between the upper pressure plate 16 and the inner wall of the reactor 1 to seal the gap therebetween. The upper pressure plate 16 moves up and down inside the reactor 1 through a driving mechanism 1.

[0028] The driving mechanism 1 includes an electric push rod 7, which is installed on the upper surface of the reactor 1. A connecting pipe 5 is fixedly embedded on the upper surface of the upper pressure plate 16, and the upper end of the connecting pipe 5 passes through the upper side wall of the reactor 1 and is slidably connected to the reactor 1. The connecting pipe 5 can drive the upper pressure plate 16 to move up and down inside the reactor 1.

[0029] The upper end of the connecting tube 5 is rotatably connected to the fixed plate 10, and the telescopic end of the electric push rod 7 is fixedly connected to the bottom surface of the fixed plate 10, so that the electric push rod 7 can drive the upper pressure plate 16 to move up and down through the connecting tube 5.

[0030] The lower pressure plate 6 is horizontally arranged inside the reactor 1 and is slidably sealed with the inner wall of the reactor 1. The lower pressure plate 6 is circular in design and fits with the inner wall of the reactor 1. A rubber ring is arranged at the connection between the lower pressure plate 6 and the inner wall of the reactor 1 to seal the gap therebetween, and the lower pressure plate 6 is located below the upper pressure plate 16. The lower pressure plate 6 moves up and down inside the reactor 1 through a second driving mechanism. The second driving mechanism includes a second electric push rod 15, which is installed on the upper surface of the reactor 1. A connecting rod 8 is fixedly connected to the upper surface of the lower pressure plate 6. The connecting rod 8 is slidably arranged in the connecting tube 5, so that the inner cavity of the connecting tube 5 can serve as an avoidance zone for the connecting rod 8 to pass through, so that the connecting rod 8 can drive the upper pressure plate 16 to move up and down inside the reactor 1.

[0031] The upper end of the connecting rod 8 is fixedly connected to the fixed arm 14, and the telescopic end of the electric push rod 15 is fixedly connected to the bottom surface of the fixed arm 14, so that the electric push rod 15 can drive the lower pressure plate 6 to move up and down through the connecting rod 8. A plurality of through holes 19 are opened in the upper pressure plate 16. The solution between the upper pressure plate 16 and the lower pressure plate 6 seeps out from the through holes 19, and the purified slag remains between the upper pressure plate 16 and the lower pressure plate 6. The upper pressure plate 16 and the lower pressure plate 6 can move relative to each other, thereby squeezing the purified slag between the upper pressure plate 16 and the lower pressure plate 6, exposing the zinc powder in the purified slag that cannot participate in the reaction, so that it participates in the reaction, without adding excessive zinc powder, thereby saving costs.

[0032] A motor 12 is arranged on the fixed plate 10, and a driving gear 13 and a driven gear 11 are respectively fixed on the output shaft of the motor 12 and the surface of the connecting pipe 5, and the driving gear 13 is meshed with the driven gear 11, so that the upper pressure plate 16 can rotate while squeezing the precipitated slag downward, thereby improving the crushing effect of the precipitated slag. A plurality of grinding blocks 18 are arranged on the opposite surfaces of the upper pressure plate 16 and the lower pressure plate 6, and the grinding blocks 18 can be provided to further improve the crushing effect of the precipitated slag.

[0033] A connecting plate 20 is slidably provided on the surface of the connecting tube 5, and a paddle 17 is vertically provided on the bottom surface of the connecting plate 20. An opening adapted to the paddle 17 is opened on the upper surface of the upper pressing plate 16, and the paddle 17 passes through the opening and extends to the bottom of the upper pressing plate 16. When the zinc powder and the zinc sulfate solution react between the upper pressing plate 16 and the lower pressing plate 6, the upper pressing plate 16 rotates, which can drive the paddle 17 to rotate and stir the zinc powder and the zinc sulfate solution. When the upper pressing plate 16 and the lower pressing plate 6 are closed to grind and purify the slag, the paddle 17 is moved upward by the resistance of the lower pressing plate 6. Therefore, the paddle 17 does not affect the upper pressing plate 16 and the lower pressing plate 6 to extrude the ground precipitated slag.

[0034] A spring 9 is sleeved on the surface of the connecting tube 5, and both ends of the spring 9 are fixed to the connecting plate 20 and the connecting tube 5 respectively. The setting of the spring 9 can restore the paddle 17 with it when the upper pressing plate 16 is separated from the lower pressing plate 6.

[0035] The discharge valve 2 of the reactor 1 is located between the lower pressure plate 6 and the upper pressure plate 16. The reactor 1 has two symmetrical windows 3, and a sealing cover 4 is provided on the window 3. After purification, the connecting rod 8 and the lower pressure plate 6 are driven to move upward, so that the lower pressure plate 6 drives the solution and the precipitate to move upward, and the purified solution flows out of the reactor 1 through the discharge valve 2. After all the solution is released, the lower pressure plate 6 also moves to the window 3, and the precipitate on the lower pressure plate 6 is cleaned through the window 3. This design facilitates the cleaning of the precipitate and realizes solid-liquid separation at the same time.

[0036] Working principle:

[0037] The zinc sulfate solution and zinc powder to be purified are placed in the reaction kettle 1, and the upper pressing plate 16 drives a plurality of blades 17 to rotate, so that the blades 17 stir the zinc sulfate solution, thereby accelerating the reaction between the zinc powder and the zinc sulfate solution;

[0038] The upper pressing plate 16 is driven downward by the electric push rod 7 to move the upper pressing plate 16 close to the lower pressing plate 6, and the upper pressing plate 16 and the lower pressing plate 6 cooperate to crush the precipitated purification slag to release the zinc powder in the precipitated slag, and then the upper pressing plate 16 and the lower pressing plate 6 are separated to rotate the upper pressing plate 16 and the paddle 17 to rotate so that all the zinc powder can play a role;

[0039] After purification, the solution and the precipitate are moved upward by the lower pressure plate 6, so that the purified solution flows out of the reactor 1 through the discharge valve 2. After all the solution is released, the lower pressure plate 6 also moves to the window 3, and the precipitate on the lower pressure plate 6 is cleaned through the window 3.
