Description

Technical Field

[0001] The utility model relates to the technical field of nonferrous metal smelting production, in particular to a zinc sulfate solution purification device. Background Art

[0002] Zinc sulfate is colorless or white crystals, granules or powders, also known as Haofan. As an important material, zinc sulfate is used in many fields. It is mainly used as a raw material for making some pigments, animal nutrients, feed additives, zinc fertilizers for crops, important materials for artificial fibers, and electrolytes for electrolytic production of metallic zinc. In the production process of zinc sulfate, zinc powder needs to be replaced with sulfuric acid solution. After the replacement, the zinc sulfate solution will still contain zinc powder impurities and replaced impurities. If it is not purified, it will affect its production quality.

[0003] In the existing industrial zinc sulfate solution production, during the purification process of the zinc sulfate solution by the zinc sulfate solution purification device, due to the different replacement reaction times of different metals, the purity of the zinc sulfate solution obtained by one purification is not enough if a single barrel is replaced. In most cases, it is necessary to further design a multi-barrel multi-stage purification. On the one hand, the equipment occupies a large area, and on the other hand, it leads to low purification efficiency in the production process. Summary of the invention

[0004] In view of this, the purpose of the utility model is to provide a zinc sulfate solution purification device with sufficient replacement reaction and high purification efficiency.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is a zinc sulfate solution purification device, comprising:

[0006] Shell: A discharge port is provided at the bottom of the left wall of the shell, and a discharge pipe is fixedly connected to the bottom of the right wall of the shell;

[0007] Reaction chamber: The reaction chamber is fixedly arranged on the upper left side of the shell, an overflow port is provided on the top right side of the reaction chamber, and a vertically transparent connecting port is provided at the bottom of the reaction chamber, and the connecting port can control on and off;

[0008] Feed pipe: the feed pipe is located above the reaction chamber;

[0009] Stirring device: The stirring device is arranged in the reaction chamber;

[0010] Guide body: the guide body is fixed on the right outer wall of the reaction chamber, and the upper surface of the guide body is an overflow surface inclined to the lower right;

[0011] Zinc powder box: the zinc powder box is fixed on the overflow surface;

[0012] Filter plate: The filter plate is fixed obliquely below the reaction chamber, with the left side of the filter plate fixed at the lower left corner inside the shell, and the right side of the filter plate against the right inner wall of the shell.

[0013] The beneficial effect of the above technical scheme is that in the process of purifying the zinc sulfate solution, firstly, the zinc sulfate leachate is added with zinc powder to carry out a replacement reaction in the reaction chamber. During the whole process, the stirring device keeps stirring to ensure that the leachate and the zinc powder react fully. As the production proceeds, the solution in the reaction chamber gradually increases, and then overflows from the overflow port on the right side of the reaction chamber after reaching a certain amount. The overflowing solution continues to contact the fixed zinc powder box on the overflow surface of the guide body for secondary replacement, ensuring that the entire leachate is fully replaced with the zinc powder, and then solid-liquid separation is carried out through the filter plate below, and the replaced heavy metals are collected at the lower left of the shell, and the purified zinc sulfate solution flows out from the discharge pipe at the lower right of the shell. When the production is completed, the valve of the connecting valve below the reaction chamber is opened, and the solution in the reaction chamber can also fall through the filter plate to separate the heavy metals, and all the heavy metals can be taken out through the discharge port on the left side, which is convenient and quick.

[0014] Furthermore, a connecting valve is provided at the connecting port, and the valve of the connecting valve extends outwardly from the outside of the shell.

[0015] Beneficial effect: a collection path for displaced heavy metals in the reaction chamber is provided, and the zinc sulfate solution in the reaction chamber is conveniently discharged after production is completed through a connecting valve.

[0016] Furthermore, the stirring device includes a stirring motor and a stirring shaft, the stirring shaft vertically extends into the reaction chamber, and the top of the stirring shaft is fixedly connected to the rotating shaft of the stirring motor.

[0017] Beneficial effects: During the first replacement process of zinc powder and leachate, stirring is used to ensure that zinc powder and zinc sulfate leachate are fully in contact with each other for replacement reaction, thereby improving the purification effect of zinc sulfate solution.

[0018] Furthermore, a paddle is fixedly connected to the bottom of the stirring shaft.

[0019] Beneficial effect: Improve the stirring ability of the stirring shaft on the solution and enhance the stirring effect.

[0020] Furthermore, zinc powder boxes are fixed on the overflow surface at intervals along the inclined direction of the overflow surface, and overflow grooves are formed between adjacent zinc powder boxes.

[0021] Beneficial effects: increase the contact angle between zinc powder and solution, expand the contact area between overflowing solution and zinc powder, and ensure the purification effect of secondary replacement of zinc sulfate solution.

[0022] Furthermore, a handle is provided on the discharge port.

[0023] Beneficial effect: It is convenient to open the discharge port when collecting heavy metals. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following is a further detailed description of a zinc sulfate solution purification device of the utility model in conjunction with the accompanying drawings and specific implementation methods.

[0029] like Figure 1-3 As shown, a zinc sulfate solution purification device of the utility model comprises a shell 2, a reaction chamber 10, a feed pipe 1, a stirring device, a flow guide 12, a zinc powder box 16 and a filter plate 13. A discharge port 7 is arranged at the bottom of the left wall of the shell 2, and a handle 8 is arranged on the discharge port 7 to collect the heavy metals replaced during the purification process. A discharge pipe 9 is fixedly connected to the bottom of the right wall of the shell 2. The reaction chamber 10 is fixedly arranged at the upper left side of the inside of the shell 2. An overflow port 3 is arranged at the top right side of the reaction chamber 10. A connecting port that is transparent from top to bottom is arranged at the bottom of the reaction chamber 10, and the connecting port can control the on-off. A connecting valve 14 is arranged at the connecting port. The valve 6 of the connecting valve 14 extends outside the shell to provide a collection path for the heavy metals replaced in the reaction chamber 10. The zinc sulfate solution in the reaction chamber 10 can be discharged conveniently after the production is completed through the connecting valve 14.

[0030] In this embodiment, the feed pipe 1 is located above the reaction chamber 10, the stirring device is arranged in the reaction chamber 10, the flow guide 12 is fixed on the right outer wall of the reaction chamber 10, the upper surface of the flow guide 12 is an overflow surface 15 inclined to the lower right, and the zinc powder box 16 is fixed on the overflow surface 15. As the production progresses, the solution in the reaction chamber 10 gradually increases, and the overflowing solution continues to contact the fixed zinc powder box 16 on the overflow surface 15 of the flow guide 12 for secondary replacement. The filter plate 13 is tilted and fixed below the reaction chamber 10, the left side of the filter plate 13 is fixed at the lower left corner inside the shell 2, and the right side of the filter plate 13 is against the right inner wall of the shell 2. The solution after the secondary replacement is separated into solid and liquid through the filter plate 13, and the replaced heavy metals are collected at the lower left of the shell 2, and the purified zinc sulfate solution flows out from the discharge pipe 9 at the lower right of the shell 2.

[0031] In this embodiment, the stirring device includes a stirring motor 5 and a stirring shaft 4. The stirring shaft 4 extends vertically into the reaction chamber 10. The top of the stirring shaft 4 is fixedly connected to the rotating shaft of the stirring motor 5. During the first replacement process of the zinc powder and the leachate, stirring is performed to ensure that the zinc powder and the zinc sulfate leachate are fully in contact with each other for replacement reaction, thereby improving the purification effect of the zinc sulfate solution. The bottom of the stirring shaft 4 is fixedly connected with a paddle 11 to improve the stirring ability of the stirring shaft 4 on the solution and enhance the stirring effect.

[0032] In this embodiment, zinc powder boxes 16 are fixed at intervals on the overflow surface 15 along the inclined direction of the overflow surface 15, and overflow grooves 17 are formed between adjacent zinc powder boxes 16, thereby increasing the angle at which zinc powder and solution can contact, expanding the contact area between the overflowing solution and the zinc powder, and ensuring the purification effect of the secondary replacement of the zinc sulfate solution.

[0033] When the utility model is used, the connecting valve 14 is first closed through the valve 6 to ensure that the bottom of the reaction chamber 10 is airtight, and then the solution is injected into the reaction chamber 10 through the feeding pipe 1. When the height of the solution in the reaction chamber 10 is above the blade 11, the stirring motor 5 is turned on, and then an appropriate amount of zinc powder is added into the reaction chamber 10 to start a replacement reaction. As the amount of solution injected by the feeding pipe 1 increases, the solution flows out from the overflow port 3 on the right side of the reaction chamber 10, and the outflowing solution further undergoes a secondary replacement reaction on the overflow surface 15 of the guide body 12 and the fixed zinc powder box 16. The solution after replacement falls through the filter plate 13 for solid-liquid separation. The displaced heavy metals are collected along the filter plate 13 to the lower left of the shell 2, and the purified zinc sulfate solution flows out and is collected through the discharge pipe 9 on the right side of the shell 2. After the injection of the feed pipe 1 stops, the valve 6 is opened to release all the solution in the reaction chamber 10, and the metals that have been displaced in the reaction chamber 10 can also be collected through the filter plate 13. After waiting for the right discharge pipe 9 to discharge all the zinc sulfate solution, the discharge port 7 is opened by the handle 8 to take out all the heavy metals from the device. It should be noted that during the purification process, zinc powder is added to the reaction chamber 10 in time according to the amount of solution injected by the feed pipe 1.

[0034] The utility model provides a zinc sulfate solution purification device with the following advantages: first, the solution and zinc powder in the reaction chamber are continuously stirred to ensure the replacement effect, and the overflowing solution in the reaction chamber is fully contacted with the zinc powder box through the overflow surface of the guide body for secondary replacement, thereby improving the purification effect of the zinc sulfate solution; second, the device is designed with secondary replacement but does not require double-barrel classification, thereby reducing the floor space occupied by the equipment and improving the production efficiency; third, all heavy metals replaced during the purification process are finally collected at the lower left bottom of the shell body, which is convenient for taking out from the device.

[0035] In the above embodiment, a connecting valve is provided at the connecting port, and the valve of the connecting valve extends outward from the outside of the shell. In other embodiments, a slide and a plug plate structure can be provided at the bottom of the reaction chamber, and the plug plate is pulled out to fully open the entire bottom. The bottom of the reaction chamber can also be made with an inclined slope to facilitate the complete discharge of the solution and heavy metals when it is opened.

[0036] In the above embodiment, the stirring shaft extends vertically into the reaction chamber, and the top of the stirring shaft is fixedly connected to the rotating shaft of the stirring motor. In other embodiments, the stirring motor may not be used, and other forms may be used to move the solution in the reaction chamber, such as an air pump to inflate the bottom of the reaction chamber.

[0037] In the above embodiment, zinc powder boxes are fixed at intervals on the overflow surface along the inclined direction of the overflow surface, and overflow grooves are formed between adjacent zinc powder boxes. In other embodiments, the overflow surface can be designed to be uneven, or the zinc powder boxes can be fixed end to end in a cross shape to form a tortuous overflow groove, thereby increasing the time that the solution passes through the overflow surface and improving the replacement reaction effect.

[0038] In the above embodiment, a discharge port is provided at the bottom of the left wall of the shell, and a handle is provided on the discharge port. In other embodiments, a waste chamber can be separated under the filter plate on the left side inside the shell, and heavy metals are directly collected in the waste chamber.
