Description

Technical Field

[0002] Zinc sulfate is an inorganic compound, which is colorless or white crystals, granules or powders. Zinc sulfate is mainly used as a raw material for preparing pigments such as lithopone, zinc barium white and other zinc compounds, and also as a nutrient for animals lacking zinc, a feed additive for animal husbandry, a zinc fertilizer for crops, an important material for rayon, an electrolyte for electrolytic production of metallic zinc, a mordant in the textile industry, a medicine emetic, astringent, fungicide, a preservative for wood and leather, etc. In the production process of zinc sulfate, impurity removal and filtration are key links to ensure product quality. Therefore, there is a particular need for a novel impurity removal and filtration device for zinc sulfate production.

[0003] However, in the existing novel impurity removal and filtration device for zinc sulfate production, the filtration component is extremely easy to be blocked by impurities during use, resulting in a significant reduction in filtration efficiency. This not only increases the cleaning frequency and maintenance cost, but also seriously affects the production progress. When solidifying the zinc sulfate solution, it is difficult for the traditional device to achieve uniform heating, making the zinc sulfate crystals uneven, and it is difficult to guarantee the product purity and quality.

Detailed implementation mode

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-9 , the present invention provides a technical solution: a new type of impurity removal and filtration device for zinc sulfate production, including a support base 1, a discharge cylinder 2 is installed on the upper surface of the support base 1, a discharge pipe 3 is fixedly connected to the lower surface of the discharge cylinder 2, a control valve 4 is installed on the outer surface of the discharge pipe 3, a support rod 5 is fixedly connected to the upper surface of the discharge cylinder 2, a curing cylinder 6 is fixedly connected to the upper surface of the support rod 5, a circulation pipe 7 is fixedly connected to the lower surface of the curing cylinder 6, a steam outlet 8 is fixedly connected to the outer surface of the curing cylinder 6, a first connecting pipe 9 is fixedly connected to the outer surface of the curing cylinder 6, one end surface of the first connecting pipe 9 is flange-connected to a communicating pipe 10, the other end surface of the communicating pipe 10 is flange-connected to a second connecting pipe 11, one end surface of the second connecting pipe 11 is fixedly connected to a mixing cylinder 12, a feed pipe 13 is fixedly connected to the outer surface of the mixing cylinder 12, a stirring and filtering mechanism 14 is arranged inside the mixing cylinder 12, a curing mechanism 15 is arranged on the inner surface of the curing cylinder 6, and a cooling and vibrating mechanism 16 is arranged on the inner surface of the discharge pipe 3; The stirring and filtering mechanism 14 includes a motor 1401, the motor 1401 is installed on the upper surface of the mixing cylinder 12, a rotating shaft 1402 is fixedly connected to one end surface of the motor 1401, a sealing workpiece 1403 is rotatably connected to the outer surface of the rotating shaft 1402, a stirring blade 1404 is fixedly connected to the outer surface of the rotating shaft 1402, a filter plate 1405 is fixedly connected to the inner surface of the mixing cylinder 12, a filter hole 1406 is formed on the surface of the filter plate 1405, a dirt removing block 1415 is slidably connected to the inner surface of the filter hole 1406, the stirring and filtering mechanism 14 further includes a connecting rod 1407, the connecting rod 1407 is installed on the outer surface of the rotating shaft 1402, a fixing column 1408 is fixedly connected to the upper surface of the connecting rod 1407, a sliding groove 1409 is formed on the inner surface of the fixing column 1408, a sliding block 1410 is slidably connected to the inner surface of the sliding groove 1409, a spring 1411 is fixedly connected to one end surface of the sliding block 1410, a connecting column 1412 is fixedly connected to the other end surface of the sliding block 1410, a limiting block 1413 is fixedly connected to one end surface of the connecting column 1412, a limiting groove 1414 is formed on the inner surface of the fixing column 1408, a dirt removing block 1415 is fixedly connected to one end surface of the limiting block 1413, a filter membrane 1416 is fixedly connected to the inner surface of the communicating pipe 10. Through the setting of the above structure, when in use, after the zinc block and the zinc sulfate mixed liquid enter the mixing cylinder 12, the motor 1401 is started, the motor 1401 drives the rotating shaft 1402 to rotate, and the stirring blade 1404 on the rotating shaft 1402 rotates accordingly to stir the mixed liquid to make it fully mixed. The mixed liquid flows to the filter plate 1405, and larger impurity particles are blocked by the filter plate 1405, while smaller particles and liquid pass through the filter holes 1406. At the same time, the rotation of the rotating shaft 1402 drives the connecting rod 1407 to rotate, and the fixing column 1408 moves with the connecting rod 1407. When the dirt removing block 1415 slides on the surface of the filter plate 1405, the spring 1411 is compressed. When the dirt removing block 1415 moves to the position of the filter hole 1406, the elastic potential energy of the spring 1411 is released, pushing the sliding block 1410, so that the limiting block 1413, the connecting column 1412 and the dirt removing block 1415 pop out. The dirt removing block 1415 scrapes the inner wall of the filter hole 1406 to remove the attached impurities. The control valve 4 outside the second connecting pipe 11 is opened, and the liquid preliminarily filtered by the filter plate 1405 enters the communicating pipe 10 through the second connecting pipe 11 and is further filtered by the filter membrane 1416 to remove smaller impurity particles.

[0020] Further, multiple groups of control valves 4 are provided and are respectively arranged on the outer surfaces of the discharge pipe 3, the circulation pipe 7, and the second connecting pipe 11. The discharge cylinder 2 is fixedly connected to the curing cylinder 6 through the circulation pipe 7. Multiple groups of support rods 5 are arranged on the upper surfaces of the curing cylinder 6 and the discharge cylinder 2. The discharge cylinder 2 is fixedly connected to the curing cylinder 6 through multiple groups of support rods 5. The curing cylinder 6 is fixedly connected to the mixing cylinder 12 through multiple groups of support rods 5. Through the setting of the above structure, during use, during the operation of the device, the operator can control the opening and closing and the flow rate of the discharge pipe 3, the circulation pipe 7, and the second connecting pipe 11 according to production requirements. When it is necessary to transport the filtered liquid in the mixing cylinder 12 to the curing cylinder 6, the control valve 4 on the second connecting pipe 11 is opened. When the solidified zinc sulfate needs to enter the discharge cylinder 2, the control valve 4 on the circulation pipe 7 is opened. Finally, the finished zinc sulfate is discharged from the discharge pipe 3. The discharge speed is adjusted by controlling the control valve 4 on the discharge pipe 3. The support rods 5 provide stable support for each component, ensuring that the relative positions of each part of the device are fixed, so that the material can be orderly transported between the components along the set path.

[0021] Further, the rotating shaft 1402 passes through the discharge cylinder 2, the curing cylinder 6, and the mixing cylinder 12. The sealing workpiece 1403 is installed at the bottom of the discharge cylinder 2. The sealing workpiece 1403 is installed at the top and bottom of the curing cylinder 6. The sealing workpiece 1403 is installed at the top of the mixing cylinder 12. Through the setting of the above structure, during use, the rotating shaft 1402, as the core transmission component, penetrates the discharge cylinder 2, the curing cylinder 6, and the mixing cylinder 12, and synchronously drives the relevant components of the stirring and filtering mechanism 14, the curing mechanism 15, and the cooling and vibrating mechanism 16 to rotate under the drive of the motor 1401. The sealing workpieces 1403 are respectively installed at the key positions of each cylinder to form a sealing structure. During the rotation of the rotating shaft 1402, it prevents the liquid in the cylinder from leaking and at the same time prevents external impurities from entering the cylinder. The penetrating design of the rotating shaft 1402 realizes the operation of multiple mechanisms driven by one power source, simplifies the device structure, reduces the number of power components used, and reduces the equipment cost and energy consumption.

[0022] Furthermore, the upper half of the filtering hole 1406 is cylindrical, and the lower half is arc-shaped. The top of the dirt removing block 1415 is semi-circular. With the above structural arrangement, during use, under the action of pressure or gravity, the mixed liquid enters from the cylindrical upper part of the filtering hole 1406. Larger impurity particles are intercepted on the surface of the filter plate 1405. After the liquid and smaller particles pass through, they smoothly flow out from the arc-shaped lower part. When the dirt removing block 1415 rotates to the position of the filtering hole 1406 along with the rotating shaft 1402, since the top of the dirt removing block 1415 is semi-circular and is adapted to the arc-shaped lower part of the filtering hole 1406, it can smoothly enter the interior of the filtering hole 1406 and remove the impurities adhering to the hole wall through a scraping action. The design of the upper cylindrical part and the lower arc-shaped part of the filtering hole 1406 not only ensures the effective interception of impurity particles but also facilitates the smooth passage of the liquid, improving the filtering efficiency.

[0023] Furthermore, multiple groups of fixed columns 1408 are arranged at equal intervals on the upper surface of the connecting rod 1407. The outer dimension of the limiting block 1413 matches the inner dimension of the limiting groove 1414. With the above structural arrangement, during use, during the rotation of the rotating shaft 1402, the connecting rod 1407 drives the fixed columns 1408 to rotate. The multiple groups of fixed columns 1408 arranged at equal intervals ensure that the dirt removing blocks 1415 are evenly distributed on the filter plate 1405, and all the filtering holes 1406 can be cleaned. When the dirt removing block 1415 is ejected by the elastic force of the spring 1411, the limiting block 1413 is inserted into the limiting groove 1414. Since the outer dimension of the limiting block 1413 matches the inner dimension of the limiting groove 1414, the ejection distance and movement direction of the dirt removing block 1415 are restricted, ensuring that the dirt removing block 1415 accurately cleans the filtering hole 1406. After the cleaning is completed, under the action of the rotation of the rotating shaft 1402 and the pulling force of the spring 1411, the limiting block 1413 disengages from the limiting groove 1414, and the dirt removing block 1415 retracts. The precise cooperation between the limiting block 1413 and the limiting groove 1414 makes the ejection and retraction actions of the dirt removing block 1415 more stable and accurate, avoiding the influence of excessive ejection or direction deviation of the dirt removing block 1415 on the cleaning effect and even damage to the filter plate 1405, and improving the reliability and safety of the device operation.

[0024] Furthermore, the curing mechanism 15 includes a heating rod 1501. The heating rod 1501 is installed on the outer surface of the rotating shaft 1402. A scraping block 1502 is slidably connected to the outer surface of the heating rod 1501. A stop block 1503 is fixedly connected to one end surface of the heating rod 1501. An arc-shaped guide plate 1504 is fixedly connected to the outer surface of the rotating shaft 1402. A fixing rod 1505 is fixedly connected to the outer surface of the rotating shaft 1402. A scraping plate 1506 is fixedly connected to one end surface of the fixing rod 1505. A heating tube 1507 is fixedly connected to the inner surface of the curing cylinder 6. With the above structure, when in use, after the filtered zinc sulfate solution enters the curing cylinder 6, the heating tube 1507 and the heating rod 1501 start to work to heat and cure the solution. When the rotating shaft 1402 rotates, it drives the heating rod 1501, the arc-shaped guide plate 1504, the fixing rod 1505 and the scraping plate 1506 to rotate synchronously. The arc-shaped guide plate 1504 makes the solution flow around the heating rod 1501. Due to the direction setting of the three groups of arc-shaped guide plates 1504, the solution forms a complex flow path in the curing cylinder 6, increasing the contact time and contact area between the solution and the heating rod 1501 and the heating tube 1507, realizing uniform heating. At the same time, the rotating heating rod 1501 makes the scraping block 1502 be thrown to the other end of the heating rod 1501 under the action of centrifugal force until it is blocked by the stop block 1503. The scraping block 1502 scrapes the outer wall of the heating rod 1501 during the movement to remove the attached crystalline substances, and the scraping plate 1506 scrapes the inner wall of the curing cylinder 6 to prevent the solution from solidifying and accumulating on the cylinder wall.

[0025] Furthermore, both the arc-shaped guide plate 1504 and the heating rod 1501 are inclined and fixed on the outer surface of the rotating shaft 1402. The arc-shaped guide plate 1504 is installed around the heating rod 1501. There are three groups of the arc-shaped guide plate 1504 and the heating rod 1501 arranged vertically. The middle group of arc-shaped guide plates 1504 has the opposite direction to the other two groups. With the above structure, when in use, since the arc-shaped guide plate 1504 is installed around the heating rod 1501 and is inclined and fixed, it will push the zinc sulfate solution to flow along an arc path when rotating, making it surround the heating rod 1501. Among the three groups of arc-shaped guide plates 1504, the middle group has the opposite direction to the other two groups, which makes the solution form a complex and three-dimensional flow trajectory in the curing cylinder 6. During the flow of the solution, it continuously contacts the heating rod 1501 and the heating tube 1507, increasing the contact area and contact time with the heating components, realizing uniform and efficient heating. During the flow of the solution, the heated solution can perform more sufficient heat exchange due to the temperature change and the disturbance generated by the flow, promoting the crystallization and curing of zinc sulfate and improving the uniformity of heating of the zinc sulfate solution.

[0026] Furthermore, the cooling and vibrating mechanism 16 includes an inclined scraper 1601 which is installed on the outer surface of the rotating shaft 1402. One end surface of the rotating shaft 1402 is fixedly connected with a rotating disc 1602. The outer surface of the rotating disc 1602 is fixedly connected with a pushing plate 1603. The upper surface of the rotating disc 1602 is fixedly connected with a jacking block 1604. The outer surface of the rotating shaft 1402 is slidably connected with a chassis 1605. The lower surface of the chassis 1605 is fixedly connected with a floating block 1606. The upper surface of the chassis 1605 is fixedly connected with a vibrating disc 1607. The surface of the vibrating disc 1607 is provided with sieve holes 1608. The inner wall surface of the discharge cylinder 2 is provided with a limiting ring 1609. The inner surface of the discharge cylinder 2 is fixedly connected with a refrigeration pipe 1610. Through the setting of the above structure, when in use, after the solidified zinc sulfate enters the discharge cylinder 2 through the flow pipe 7, the refrigeration pipe 1610 starts to cool the zinc sulfate. At the same time, the rotation of the rotating shaft 1402 drives the rotation of the rotating disc 1602, and the jacking block 1604 on the rotating disc 1602 rotates accordingly. When the jacking block 1604 meshes with the floating block 1606, it pushes the floating block 1606, causing the chassis 1605 and the vibrating disc 1607 to move upward. When the jacking block 1604 disengages from the floating block 1606, under the action of gravity, the chassis 1605 and the vibrating disc 1607 fall. Repeating this way, the up-and-down vibration of the vibrating disc 1607 is realized. Since vibration can, to a certain extent, help shake loose the agglomerated zinc sulfate, the vibration generated by the vibrating disc 1607 can effectively destroy the agglomerated structure of zinc sulfate, reduce the friction and adhesion force between particles, and promote the loosening of the agglomerates. At the same time, the sieve holes 1608 on the vibrating disc 1607 can screen out unqualified large particles or agglomerated zinc sulfate that is not completely dispersed. When the inclined scraper 1601 rotates with the rotating shaft 1402, it scrapes the inner wall of the discharge cylinder 2 to prevent zinc sulfate from adhering to the cylinder wall. The limiting ring 1609 limits the vibration range of the vibrating disc 1607, ensures the stability of the vibration process, and avoids affecting the operation of the equipment and the screening effect due to excessive vibration amplitude.

[0027] Furthermore, the lifting block 1604 meshes with the floating block 1606. There are multiple sets of the lifting block 1604 and the floating block 1606. The diameter of the lifting block 1604 is smaller than that of the floating block 1606. The inclined scraper 1601 fits against the inner wall of the curing cylinder 6. There are two sets of the limit rings 1609 provided on the upper and lower surfaces of the vibrating disk 1607. With the above-described structure, during use, when the lifting block 1604 continues to rotate with the rotating disk 1602 and disengages from the floating block 1606, the chassis 1605 and the vibrating disk 1607 fall under their own gravity. Repeating this process, the rotating disk 1602 continues to rotate, causing the vibrating disk 1607 to continuously vibrate up and down. The up-and-down vibration of the vibrating disk 1607 can, to a certain extent, help shake loose the agglomerated zinc sulfate. Through vibration, the mutual force between the originally agglomerated zinc sulfate particles is destroyed, and the agglomeration gradually loosens, making the particle size of the product more uniform. The limitation of the vibration range of the vibrating disk 1607 by the limit ring 1609 ensures the stability of the vibration process.

[0028] Working principle: The operator can control the opening and closing and the flow rate of the discharge pipe 3, the circulation pipe 7, and the second connecting pipe 11 according to the production requirements through the control valve 4. When it is necessary to transport the filtered liquid in the mixing cylinder 12 to the solidification cylinder 6, open the control valve 4 on the second connecting pipe 11. When the solidified zinc sulfate needs to enter the discharge cylinder 2, open the control valve 4 on the circulation pipe 7. Finally, the finished zinc sulfate is discharged from the discharge pipe 3, and the discharge speed is adjusted by controlling the control valve 4 on the discharge pipe 3. The support rod 5 provides stable support for each component, ensuring that the relative positions of all parts of the device are fixed, enabling the material to be orderly transported between each component along the set path. After the zinc block and the zinc sulfate mixed liquid enter the mixing cylinder 12, start the motor 1401. The motor 1401 drives the rotation shaft 1402 to rotate, and the stirring blades 1404 on the rotation shaft 1402 rotate accordingly to stir the mixed liquid to make it fully mixed. The mixed liquid flows towards the filter plate 1405, and larger impurity particles are blocked by the filter plate 1405, while smaller particles and liquid pass through the filter holes 1406. At the same time, the rotation of the rotation shaft 1402 drives the connecting rod 1407 to rotate, and the fixed column 1408 moves with the connecting rod 1407. When the dirt removal block 1415 slides on the surface of the filter plate 1405, the spring 1411 is compressed. When the dirt removal block 1415 moves to the position of the filter hole 1406, the elastic potential energy of the spring 1411 is released, pushing the sliding block 1410, causing the limit block 1413, the connecting column 1412, and the dirt removal block 1415 to pop out. The dirt removal block 1415 scrapes the inner wall of the filter hole 1406 to remove the attached impurities. Open the control valve 4 outside the second connecting pipe 11, and the liquid preliminarily filtered by the filter plate 1405 enters the connecting pipe 10 through the second connecting pipe 11 and is further filtered by the filter membrane 1416 to remove smaller impurity particles. When the filtered zinc sulfate solution enters the solidification cylinder 6, the heating tube 1507 and the heating rod 1501 start to work to heat and solidify the solution. When the rotation shaft 1402 rotates, it drives the heating rod 1501, the arc-shaped guide plate 1504, the fixed rod 1505, and the scraper 1506 to rotate synchronously. The arc-shaped guide plate 1504 makes the solution flow around the heating rod 1501. Due to the direction setting of the three groups of arc-shaped guide plates 1504, the solution forms a complex flow path in the solidification cylinder 6, increasing the contact time and contact area between the solution and the heating rod 1501 and the heating tube 1507 to achieve uniform heating. At the same time, the rotating heating rod 1501 causes the scraping block 1502 to be thrown to the other end of the heating rod 1501 under the action of centrifugal force until it is blocked by the stop block 1503. The scraping block 1502 scrapes the outer wall of the heating rod 1501 during the movement to remove the attached crystalline substances, and the scraper 1506 scrapes the inner wall of the solidification cylinder 6 to prevent the solution from solidifying and accumulating on the cylinder wall. After the solidified zinc sulfate enters the discharge cylinder 2 through the circulation pipe 7, the refrigeration pipe 1610 starts to cool the zinc sulfate. At the same time, the rotation of the rotation shaft 1402 drives the rotating disk 1602 to rotate, and the lifting block 1604 on the rotating disk 1602 rotates accordingly.When the lifting block 1604 meshes with the floating block 1606, it pushes the floating block 1606, causing the chassis 1605 and the vibrating disk 1607 to move upward. After the lifting block 1604 disengages from the floating block 1606, under the action of gravity, the chassis 1605 and the vibrating disk 1607 fall. Repeating this process realizes the up-and-down vibration of the vibrating disk 1607. Since vibration can, to a certain extent, help disperse the agglomerated zinc sulfate, the vibration generated by the vibrating disk 1607 can effectively destroy the agglomerated structure of zinc sulfate, reducing the frictional force and adhesion force between particles and promoting the loosening of the agglomerates. At the same time, the sieve holes 1608 on the vibrating disk 1607 can screen out unqualified large particles or agglomerated zinc sulfate that has not been fully dispersed. When the inclined scraper 1601 rotates on the rotating shaft 1402, it scrapes the inner wall of the discharge cylinder 2 to prevent zinc sulfate from adhering to the cylinder wall. The limit ring 1609 restricts the vibration range of the vibrating disk 1607, ensuring a stable vibration process and avoiding affecting the operation of the equipment and the screening effect due to excessive vibration amplitude.
