It can also be used as a mordant for printing and dyeing, a preservative for wood and leather, and an important auxiliary raw material for the production of viscose fiber and vinylon fiber.

[0003] During the preparation of zinc sulfate, some metal impurities or sand and gravel will be mixed in, and it is necessary to filter and remove impurities, otherwise it will affect the quality and purity of the zinc sulfate. The existing screening device uses a screen for screening. During the screening process, the zinc sulfate powder will stick to the inner wall of the filter chamber and the filter, making it difficult to recycle the zinc sulfate, resulting in a certain amount of waste. In addition, due to the large holes in the filter, some small particle impurities cannot be filtered well.

DETAILED DESCRIPTION

[0030] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods:

[0031] Embodiment 1, this embodiment aims to provide a zinc sulfate refining and impurity removal device, which is mainly used for removing impurities from zinc sulfate. In view of the problems that zinc sulfate powder will stick to the inner wall of the filter chamber and the filter screen in the existing zinc sulfate impurity removal process, it is difficult to recover the zinc sulfate, and some small particle impurities cannot be well filtered due to the large holes of the filter screen, this embodiment provides a zinc sulfate refining and impurity removal device.

[0032] like Figure 1-3 As shown in the figure, a zinc sulfate refining and impurity removal device is characterized in that it includes: a filter chamber 1, a drive chamber 2, a waste chamber 3, a primary filter screen 7, a secondary filter screen 9, a drive mechanism and a spray mechanism; a feed port 13 is provided above the filter chamber 1, and a discharge port 14 is provided below the filter chamber 1; the left side of the filter chamber 1 is fixedly connected to the drive chamber 2, and the right side of the filter chamber 1 is fixedly connected to the waste chamber 3, the filter chamber 1 is connected to the drive chamber by opening a first through hole 4, and the filter chamber 1 is connected to the waste chamber 3 by opening a second through hole 5, and a spring 6 is fixed in the first through hole 4 and the second through hole 5, and the first through hole 4 is higher than the second through hole 5.

[0033] The primary filter screen 7 is a mesh filter screen that can intercept large particles of impurities and allow zinc sulfate powder to pass through. The primary filter screen 7 is arranged obliquely in the filter chamber 1, and its two ends are respectively inserted into the first through hole 4 and the second through hole 5, and are fixedly connected to the springs 6 therein respectively. A transmission block 8 is fixed to the side of the primary filter screen 7 close to the drive chamber 2, and large particles of impurities can roll on the primary filter screen 7 and fall into the waste chamber 3.

[0034] A waste box 10 is inserted into the waste chamber 3, and large particles of impurities falling into the waste chamber 3 are collected by the waste box 10. The front half of the bottom of the waste box 10 is an inclined surface inclined toward the filter chamber 1, and the rear half is a flat surface. A handle 12 is also fixed to the waste box 10. An inclined three-stage filter screen 11 is arranged in the waste chamber 3, and the bottom end of the three-stage filter screen 11 is aligned with the middle of the waste box 10.

[0035] The driving mechanism includes a driving motor 17, a driving shaft 19 and a cam 21. The driving motor 17 is fixed in the driving chamber 2. A first gear 18 is fixedly mounted on the motor shaft. The driving shaft 19 is horizontally arranged below the transmission block 8. Both ends of the first gear 18 are rotatably mounted on the two side walls of the driving chamber 2. A second gear 20 and a cam 21 are fixedly mounted on the driving shaft 19. The second gear 20 is meshed with the first gear 18. The cam 21 abuts against the bottom of the transmission block 8. When the driving motor 17 is started, the motor shaft of the driving motor 17 drives the first gear 18 rotates, the first gear 18 transmits the power to the second gear 20, the second gear 20 drives the driving shaft 19 to rotate, the driving shaft 19 drives the cam 21 to rotate, the cam 21 keeps pushing the transmission block 8, thereby transmitting the force to the primary filter screen 7, so that the primary filter screen 7 keeps vibrating, and the zinc sulfate powder and the large particles of impurities are separated. The large particles of impurities roll on the primary filter screen 7 until they fall into the waste box 10. A flip cover 15 is hinged on the top of the driving chamber 2. By opening the flip cover 15, the driving mechanism can be inspected and processed.

[0036] The secondary filter screen 9 includes a support frame 901 and a filter screen 902. The filter screen 902 is a cloth-like filter screen that can filter small particles that are insoluble in water. The filter screen 902 is fixed on the support frame 901 to ensure that the filter screen 902 has a certain tension. A handle 12 is also fixed on the support frame 901. A slot is provided on the filter chamber 1 between the bottom end of the filter chamber 1 and the primary filter screen 7. The secondary filter screen 9 is plugged into the filter chamber 1. The zinc sulfate powder screened by the primary filter screen 7 will accumulate on the secondary filter screen 9.

[0037] The spray mechanism includes a water pump 22, a spray head 23 and a pipe 24. The water pump 22 is fixed above the filter chamber 1. The spray head 23 is arranged inside the filter chamber 1 and connected to the water pump 22 through the pipe 24. After the water pump 22 pumps clean water to the spray head 23, the spray head 23 sprays water around to wash away the zinc sulfate powder adhering to the inner wall of the filter chamber 1 and the primary filter screen 7, so that it falls onto the secondary filter screen 9. An inwardly inclined baffle 16 is fixed above the first through hole 4 and the second through hole 5, which can guide the sprayed water and the coarse zinc sulfate powder falling from the feed port 13 to the bottom end of the filter chamber 1, thereby preventing a large amount of powder and water from entering the drive chamber 2 and the waste chamber 3.

[0038] After cleaning by the spray mechanism, the zinc sulfate powder accumulated on the secondary filter screen 9 combines with water to form a zinc sulfate solution, which is filtered by the secondary filter screen 9 and stored at the bottom of the filter chamber 1. The zinc sulfate solution can be taken out through the discharge port 14 for subsequent processing and use. Small particles of impurities insoluble in water will adhere to the secondary filter screen 9. After a period of use, the secondary filter screen 9 can be taken out for cleaning.

[0039] Since the primary filter screen 7 is vibrating, it is inevitable that part of the solution remaining thereon is splashed into the waste box 10. This part of the solution will enter the waste box together with the large particles of impurities. After being filtered by the third-stage filter screen 11, the large particles of impurities roll into the second half of the waste box 10, and the solution flows into the inclined surface of the first half of the waste box 10, and flows back into the filter chamber 1 through the reflux port 25 opened on the waste chamber 3, thereby reducing the waste of zinc sulfate.
