Description

Technical Field

[0001] This utility model relates to the field of high-purity copper sulfate production technology, specifically to a high-purity copper sulfate production filtration device. Background Technology

[0002] In the crystallization or solution concentration process of high-purity copper sulfate, residual free water (such as water of crystallization or adsorbed water) will directly affect the crystal structure, particle size distribution and chemical stability. Especially in the production of electronic-grade copper sulfate (such as for PCB electroplating or photovoltaic materials), excessive moisture will cause problems such as abnormal conductivity, uneven coating or battery performance degradation. Therefore, a high-purity copper sulfate production filtration device is needed for filtration.

[0003] However, existing high-purity copper sulfate production filtration devices typically rely on a single dehydration process (such as screw extrusion alone), which has low water removal efficiency and high energy consumption, making it difficult to meet the continuous production requirements of high-purity copper sulfate. Furthermore, without pre-dehydration, when the mixed liquid directly enters the separation cylinder, the excessive water load leads to blockage of the drainage channel, and the crystals will reabsorb water during the accumulation process, reducing the purity of the product.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 As shown, this utility model provides a technical solution:

[0024] A high-purity copper sulfate production filtration device includes a feed inlet 101, a screening mechanism 102 at the bottom of the feed inlet 101, a screening cylinder 103, a discharge hopper 104 fixedly installed at the bottom of the screening cylinder 103, a separation mechanism 105 at the bottom of the discharge hopper 104, a feed inlet 101 fixedly installed on one side of the top of the screening cylinder 103, a rotary motor 201 fixedly installed on the top of the screening cylinder 103 near the feed inlet 101, a rotating shaft 202 fixedly installed on the rotating end of the rotary motor 201, and the rotating shaft 202 passing through the screening cylinder 103 and movably installed inside the screening plate 503 via bearings.

[0025] A scraper 203 is fixedly installed on the outside of the rotating shaft 202. The scraper 203 is attached to the screening plate 503. The screening plate 503 is fixedly installed inside the screening cylinder 103. A discharge hole 204 is opened on one side of the screening plate 503. A partition plate 205 is fixedly installed on the side of the screening plate 503 near the discharge hole 204. The bottom end of the partition plate 205 is fixedly installed inside the feed hopper 104.

[0026] The above scheme achieves directional introduction of copper sulfate mixture into the screening cylinder through the feed connector. The screening cylinder provides a closed processing space for the screening mechanism. The screening plate receives the material and drains water through its pores. A rotating motor drives the rotating shaft to rotate the scraper along the screening plate. The scraper pushes the material to be evenly distributed and guides the dehydrated copper sulfate crystals to the discharge hole. The dehydrated crystals are discharged into the feed hopper through the discharge hole on the screening plate. A partition plate physically separates the crystals in the feed hopper from the drained water and guides them to the separation tank. The feed hopper connects the screening mechanism and the separation mechanism to achieve continuous material transfer. The separation mechanism performs secondary dehydration and separation treatment on the crystals.

[0027] In this embodiment, preferably, the separation mechanism 105 includes a separation cylinder 301, a support platform 302 is fixedly installed on one side of the top of the separation cylinder 301, a separation groove 303 is provided on the support platform 302, a feeding hopper 104 is fixedly installed on the side of the support platform 302 near the separation groove 303, and a drainage hopper 304 is fixedly installed on the side of the separation cylinder 301 opposite to the support platform 302.

[0028] The above scheme uses a support platform and a separation tank to receive the crystals and water discharged from the hopper. The inclined structure of the separation tank guides the water to the drainage hopper for rapid discharge. The channels separated by baffles inside the separation cylinder achieve physical isolation between the crystals and the water flow. The bidirectional layout of the drainage hopper discharges the liquid from the initial drainage and the liquid from the secondary compression, respectively.

[0029] In this embodiment, preferably, a drive motor 305 is fixedly installed on the side of the separation cylinder 301 away from the drainage hopper 304, and a drive shaft 306 is fixedly installed on the drive end of the drive motor 305. The drive shaft 306 passes through the separation cylinder 301 and is movably installed in the support frame 401 through a bearing.

[0030] The above scheme provides rotational power to the helical blades through a drive motor, ensures stable propulsion of the crystals through the bearing cooperation between the drive shaft and the support frame, fixes the axial position of the drive shaft to prevent displacement through the support frame, and maintains a closed environment for the filtration process through the sealed cavity of the separation cylinder.

[0031] In this embodiment, preferably, the support frame 401 is fixedly installed on the side of the separation cylinder 301 opposite to the drive motor 305, and the drive shaft 306 is located between the support frame 401 and the separation cylinder 301 with a spring 402 sleeved on it. A pressure plate 403 is fixedly installed on one side of the spring 402, and an adjusting block 404 is fixedly installed on the other side of the spring 402.

[0032] The above scheme absorbs the crystal stacking pressure fluctuations through the elastic deformation of the spring, controls the crystal discharge gap by sliding the pressure plate along the drive shaft, limits the spring compression stroke by the adjusting block, and forms a rigid support foundation for pressure regulation by the relative fixation of the support frame and the separation cylinder.

[0033] In this embodiment, preferably, the pressure plate 403 is slidably mounted on the outside of the drive shaft 306, the pressure plate 403 is attached to one side of the separation cylinder 301, and the adjusting block 404 is threadedly mounted on one side with an adjusting screw 405, and the adjusting block 404 is slidably mounted on the side of the drive shaft 306 near the support frame 401.

[0034] The above scheme uses the screw thread to push the adjustment block to move, the adjustment block to slide and adjust the spring preload threshold, the opening and closing of the gap between the pressure plate and the separation cylinder to control the crystal discharge rate, and the axial guidance of the drive shaft to ensure the accuracy of the pressure plate sliding trajectory.

[0035] In this embodiment, preferably, the drive shaft 306 is fixedly installed with a spiral blade 406 inside the separator 301 on one side. The spiral blade 406 is disposed inside the filter screen 501. The filter screen 501 is fixedly installed inside the separator 301 on one side. A baffle 502 is fixedly installed inside the separator 301 on the other side.

[0036] The above scheme uses the rotational propulsion of the spiral blades to force the crystals to accumulate and compress within the filter screen. The crystals are trapped and residual moisture is trapped through the pores of the filter screen. The moisture is guided out of the specific drainage bucket through the channels separated by baffles. The continuous transport and dynamic dehydration balance of the crystals are achieved through the gap fit between the spiral blades and the filter screen.

[0037] In this embodiment of the high-purity copper sulfate production filtration device, the operator first fixes the separation cylinder 301 and connects it to the external copper sulfate production pipeline through the feed connector 101. Then, the copper sulfate mixture is introduced into the screening cylinder 103 through the feed connector 101 and falls onto the surface of the screening plate 503. Simultaneously, the rotating motor 201 drives the rotating shaft 202 to rotate the scraper 203 circumferentially along the screening plate 503. The scraper 203 pushes the mixture to distribute it evenly on the screening plate 503. At this time, water is drained through the pores of the screening plate 503. The drained copper sulfate crystals, under the action of the scraper 203, enter the discharge hopper 104 through the discharge hole 204 on the screening plate 503. The discharge hopper 104 is equipped with a partition plate 205, so that the drained water and copper sulfate crystals are discharged into the separation tank 303 through the discharge hopper 104 respectively. The separation tank 303 transports the water and copper sulfate crystals into the separation cylinder 301 for further processing. In the channel separated by baffle 502, water is discharged through the drain hopper 304 on one side of the bottom of the separator 301, while the initially separated copper sulfate crystals enter the channel near the filter screen 501. At this time, the drive motor 305 is energized, which drives the drive shaft 306 to drive the spiral blades 406 to rotate. The rotation of the spiral blades 406 will push the copper sulfate crystals towards the filter screen 501. The copper sulfate crystals accumulate in the filter screen 501, forming a squeezing effect, which squeezes out the remaining water in the copper sulfate crystals and discharges it through the drain hopper 304 on the other side of the bottom of the separator 301. When the pressure of the accumulated copper sulfate crystals exceeds the preset threshold of the spring 402, the pressure plate 403 slides along the drive shaft 306 and compresses the spring 402. The copper sulfate crystals are discharged from the gap between the pressure plate 403 and the separator 301. After the pressure decreases, the spring 402 rebounds and pushes the pressure plate 403 to reset and close the channel, realizing continuous filtration and dynamic pressure regulation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
