Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a pressure-resistant high-precision filtration device. Background Technology

[0002] Nickel sulfate refining primarily employs hydrometallurgical processes, including leaching, purification, and crystallization filtration. In the crystallization tank, crude nickel sulfate needs to be filtered to separate impurities; the resulting filter cake is crude nickel sulfate, while the filtrate is used for subsequent processing. During this process, the filtration equipment must be resistant to high pressure and acid corrosion, and possess high-precision filtration capabilities to remove impurities such as iron and copper.

[0003] In the filtration of nickel sulfate solutions, microporous membranes or precision filter cartridges are often required to ensure the removal of fine suspended particles and impurities. However, these filter mechanisms are prone to clogging due to their small pore size, necessitating frequent replacement and cleaning. Currently, most filtration equipment only has a single filtration path and filter mechanism. This leads to frequent pausing of the filtration process when replacing or cleaning the filter mechanism, as the filtration can only resume after the cleaning and replacement are completed. Consequently, the efficiency of the filtration process is greatly reduced. Therefore, there is an urgent need for a pressure-resistant, high-precision filtration device to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model discloses a pressure-resistant high-precision filtration device. It features a dual-head conveying mechanism and a quick-release filtration mechanism. During filtration, a nickel sulfate solution is conveyed to a coarse filtration tank to remove larger impurities. Then, a pump transports the solution to a T-tube, and one of the solenoid valves at the T-tube is opened to deliver the solution to a fine filtration tank. The fine filtration tank then uses an ultrafiltration membrane to remove fine suspended particles and impurities. The purified nickel sulfate solution is then discharged through a drain pipe. After a period of operation, this solenoid valve can be closed, and the other solenoid valve can be opened, allowing another fine filtration tank to seamlessly connect with its internal ultrafiltration membrane. The previously used ultrafiltration membrane can then be removed for cleaning and replacement without interrupting the filtration process. This significantly reduces the time wasted on replacing ultrafiltration membranes, thereby greatly improving filtration efficiency and solving the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a pressure-resistant high-precision filtration device, including a base. A coarse filter box and a fine filter box are fixedly installed on the top of the base. There are two fine filter boxes. The top of the coarse filter box is open. A pump body is connected to one side of the coarse filter box. The output end of the pump body is connected to a conduit. The top of the fine filter box is provided with a water inlet pipe. Each of the two fine filter boxes is provided with a drain pipe with a valve on opposite sides. A through insertion groove is opened on the top of the fine filter box. Two sliding grooves are opened laterally on the top of the fine filter box.

[0007] A coarse filtration mechanism, which is located inside the coarse filtration box;

[0008] A dual-head conveying mechanism includes a T-shaped tube, the top end of which is connected to the end of the guide tube away from the pump body, the bottom end of which is connected to two water inlet pipes respectively, and two solenoid valves are symmetrically arranged at the T-shaped tube.

[0009] A quick-release filtration mechanism includes two ultrafiltration membrane plates. A top plate is fixedly connected to the top of each ultrafiltration membrane plate. Sealing gaskets are attached to the bottom of both the ultrafiltration membrane plates and the bottom of the top plate. An insertion groove extends through the bottom of the ultrafiltration membrane plate. The sealing gasket at the bottom of the ultrafiltration membrane plate abuts against the inner bottom surface of the fine filtration box. The sealing gasket at the bottom of the top plate abuts against the top surface of the fine filtration box. The size of the top plate is larger than the size of the insertion groove. The ultrafiltration membrane plate is located between the inlet pipe and the outlet pipe.

[0010] An auxiliary sealing mechanism is located at the top of the fine filter box.

[0011] Furthermore, the coarse filtration mechanism includes support blocks and filter screens. Multiple support blocks are provided, and all of the support blocks are fixedly installed on the inner wall of the coarse filtration box. The filter screens are movably clipped onto the top of the multiple support blocks.

[0012] Furthermore, two handles are fixedly connected to the top of the filter screen, and the top of the handles is higher than the top opening height of the coarse filter box.

[0013] Furthermore, a set of limiting blocks is provided on both sides of the interior of the fine filtration box, and a limiting groove is formed between the same set of limiting blocks. The ultrafiltration membrane plate is located in the limiting groove formed by the two sets of limiting blocks.

[0014] Furthermore, the auxiliary sealing mechanism includes a slide, a mounting base, a pressing plate, and a pressing knob. The auxiliary sealing mechanism has two sets. The bottom of the slide is slidably connected to two sliding grooves through a sliding connector. The mounting base is L-shaped and is fixedly installed on the top of the slide. Multiple telescopic guide rods are fixedly connected to the bottom of the L-shaped turning surface of the mounting base. The top of the pressing plate is fixedly connected to the telescopic ends of the multiple telescopic guide rods. The bottom end of the pressing knob passes through the mounting base through a screw connection, and the bottom end of the pressing knob is rotatably connected to the top of the pressing plate through a rotating connector. The bottom of the pressing plate abuts against the top of the top plate.

[0015] Furthermore, an extension plate is fixedly connected to the side of the slide away from the water inlet pipe, and an abutment knob is screwed onto the extension plate, which abuts against the top of the fine filter box.

[0016] The present invention has the following advantages over the prior art:

[0017] 1. This technical solution, by incorporating a dual-head conveying mechanism and a quick-release filtration mechanism, allows the nickel sulfate solution to be conveyed to the coarse filtration tank during filtration. The coarse filtration removes larger impurities from the solution. Then, a pump transports the solution to the dual-head conveying mechanism, which opens one of two filtration paths to deliver the solution to a fine filtration tank. This fine filtration tank, with its internal quick-release filtration mechanism, performs fine filtration. When the filtration mechanism in this fine filtration tank needs replacement, the dual-head conveying mechanism switches the filtration path, allowing another fine filtration tank to seamlessly connect with its own quick-release filtration mechanism. At this point, the ultrafiltration membrane plate from the previously used quick-release filtration mechanism can be removed for cleaning and replacement without interrupting the filtration process. This process significantly reduces the time wasted on replacing ultrafiltration membrane plates, thereby greatly improving filtration efficiency and demonstrating high practicality.

[0018] 2. This technical solution incorporates an auxiliary sealing mechanism, allowing the ultrafiltration membrane plate to pass through the insertion groove during installation until the sealing gasket at the bottom of the ultrafiltration membrane plate abuts against the inner bottom surface of the fine filtration box, and the sealing gasket at the bottom of the top plate abuts against the top of the fine filtration box. At this point, the auxiliary sealing mechanism can tighten the top plate, which, together with the sealing gasket at the bottom of the top plate, improves the sealing performance of the insertion groove, effectively preventing solution leakage at the insertion groove and further enhancing the practicality of the device.

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0031] Reference Figures 1-6 A pressure-resistant high-precision filtration device includes a base 1, on the top of which a coarse filter box 2 and a fine filter box 3 are fixedly installed. There are two fine filter boxes 3. The top of the coarse filter box 2 is open. A pump body 4 is connected to one side of the coarse filter box 2. The output end of the pump body 4 is connected to a conduit 5. The top of the fine filter box 3 is provided with a water inlet pipe 6. The opposite sides of the two fine filter boxes 3 are provided with drain pipes 7 with valves. The top of the fine filter box 3 is provided with a through insertion groove 8. The top of the fine filter box 3 is provided with two horizontal sliding grooves 9. A coarse filtration mechanism 10 is located inside the coarse filter box 2.

[0032] A dual-head conveying mechanism 11 includes a T-shaped tube 1101, the top end of which is connected to the end of the conduit 5 away from the pump body 4, and the bottom of which is connected to two inlet pipes 6 respectively. Two solenoid valves 1102 are symmetrically arranged at the T-shaped tube 1101. A quick-release filtration mechanism 12 includes two ultrafiltration membrane plates 1201, the top of which is fixedly connected to a top plate 1202. The bottom of the ultrafiltration membrane plate 1201 and the top plate are also connected. The bottom of each of the 1202 plates is fixedly fitted with a sealing gasket 1203. The bottom of the ultrafiltration membrane plate 1201 penetrates the insertion groove 8. The sealing gasket 1203 at the bottom of the ultrafiltration membrane plate 1201 abuts against the inner bottom surface of the fine filter box 3. The sealing gasket 1203 at the bottom of the top plate 1202 abuts against the top surface of the fine filter box 3. The size of the top plate 1202 is larger than the size of the insertion groove 8. The ultrafiltration membrane plate 1201 is located between the inlet pipe 6 and the outlet pipe 7. An auxiliary sealing mechanism 13 is located at the top of the fine filter box 3.

[0033] The coarse filtration mechanism 10 includes a support block 1001 and a filter screen 1002. Multiple support blocks 1001 are provided, and all multiple support blocks 1001 are fixedly installed on the inner wall of the coarse filtration box 2. The filter screen 1002 is movably clipped onto the top of the multiple support blocks 1001. Two handles 1003 are fixedly connected to the top of the filter screen 1002. The top height of the handles 1003 is higher than the top opening height of the coarse filtration box 2. A set of limiting blocks 1204 is provided on both sides of the interior of the fine filtration box 3. A limiting groove is formed between the same set of limiting blocks 1204. The ultrafiltration membrane plate 1201 is located in the limiting groove formed by the two sets of limiting blocks 1204.

[0034] In the specific implementation process, when performing filtration, the nickel sulfate solution can be transported to the coarse filter box 2, where it works with the coarse filter mechanism 10 to remove larger impurity particles from the solution. Then, the solution is transported to the T-tube 1101 via the pump body 4, and one of the solenoid valves 1102 at the T-tube 1101 is opened to transport the solution to one of the fine filter boxes 3. The solution then passes through the ultrafiltration membrane plate 1201 in the fine filter box 3 to remove fine suspended particles and impurities from the solution. The purified nickel sulfate solution is then discharged through the drain pipe 7. After working for a period of time, this solenoid valve 1102 can be closed, and at the same time, another solenoid valve 1102 can be opened. Another fine filter box 3, in conjunction with its internal ultrafiltration membrane plate 1201, can then perform seamless filtration. At this point, the ultrafiltration membrane plate 1201 that was previously used for filtration can be removed for cleaning and replacement without interrupting the filtration process. This process can be repeated to greatly reduce the time wasted on replacing the ultrafiltration membrane plate 1201, thereby significantly improving the efficiency of the filtration process.

[0035] In this process, after the nickel sulfate solution is transported to the coarse filter box 2, larger impurity particles in the solution can be filtered and intercepted by the filter screen 1002, thereby performing preliminary filtration treatment on the solution.

[0036] Among them, the handle 1003 is designed to make it easier for staff to quickly lift and remove the filter screen 1002 after putting on protective gear;

[0037] The limiting block 1204 can effectively limit the position of the ultrafiltration membrane plate 1201, thereby improving the stability of the ultrafiltration membrane plate 1201. Specific Implementation Example 2:

[0039] Reference Figure 6 and Figure 7 In a preferred embodiment, the auxiliary sealing mechanism 13 includes a slide 1301, a mounting base 1302, a pressing plate 1303, and a pressing knob 1304. The auxiliary sealing mechanism 13 is provided in two sets. The bottom of the slide 1301 is slidably connected to two sliding grooves 9 through a sliding connector. The mounting base 1302 is L-shaped and is fixedly installed on the top of the slide 1301. Multiple telescopic guide rods 1305 are fixedly connected to the bottom of the L-shaped turning surface of the mounting base 1302. The top of the pressing plate 1303 is fixedly connected to the telescopic ends of the multiple telescopic guide rods 1305. The bottom end of the pressing knob 1304 passes through the mounting base 1302 through a screw connection, and the bottom end of the pressing knob 1304 is rotatably connected to the top of the pressing plate 1303 through a rotating connector. The bottom of the pressing plate 1303 abuts against the top of the top plate 1202.

[0040] An extension plate 1306 is fixedly connected to the side of the slide 1301 away from the water inlet pipe 6. An abutment knob 1307 is screwed onto the extension plate 1306, and the abutment knob 1307 abuts and tightens against the top of the fine filter box 3.

[0041] In the specific implementation process, when installing the ultrafiltration membrane plate 1201, the ultrafiltration membrane plate 1201 can be passed through the insertion groove 8 until the sealing gasket 1203 at the bottom of the ultrafiltration membrane plate 1201 abuts against the inner bottom surface of the fine filter box 3, and the sealing gasket 1203 at the bottom of the top plate 1202 abuts against the top of the fine filter box 3. At this time, the sliding seat 1301 can be adjusted to be close to the top plate 1202 in conjunction with the sliding groove 9 until the pressing plate 1303 is located above the top plate 1202. Then, the pressing knob 1304 is rotated, and the telescopic guide rod 1305 is used to move the pressing plate 1303 down to abut against the top plate 1202. This, together with the sealing gasket 1203 at the bottom of the top plate 1202, improves the sealing performance of the insertion groove 8 and effectively prevents solution leakage at the insertion groove 8.

[0042] The abutment knob 1307 can abut against the top of the fine filter box 3 to help fix the slide 1301, thereby facilitating the installation and disassembly of the ultrafiltration membrane plate 1201.

[0043] Working principle: During operation, the nickel sulfate solution is fed into the coarse filter box 2. In the coarse filter box 2, larger impurities are filtered and intercepted by the filter screen 1002, thus performing preliminary filtration. Then, the solution is pumped into the T-tube 1101 by the pump body 4, and one of the solenoid valves 1102 at the T-tube 1101 is opened to transfer the solution to a fine filter box 3. The fine filter box 3 then uses an ultrafiltration membrane 1201 to filter out fine suspended particles. Particles and impurities are filtered out, and the purified nickel sulfate solution is discharged through drain pipe 7. After working for a period of time, this solenoid valve 1102 can be closed, and another solenoid valve 1102 can be opened at the same time. Another fine filter box 3 works seamlessly with its internal ultrafiltration membrane plate 1201 to perform filtration. At this time, the ultrafiltration membrane plate 1201 that has been used for filtration can be removed for cleaning and replacement without interrupting the filtration work. This process can greatly reduce the time wasted on replacing the ultrafiltration membrane plate 1201, thereby greatly improving the efficiency of the filtration work.

[0044] When installing the ultrafiltration membrane plate 1201, the ultrafiltration membrane plate 1201 can be passed through the insertion groove 8 until the sealing gasket 1203 at the bottom of the ultrafiltration membrane plate 1201 abuts against the inner bottom surface of the fine filter box 3, and the sealing gasket 1203 at the bottom of the top plate 1202 abuts against the top of the fine filter box 3. At this time, the sliding seat 1301 can be adjusted to be close to the top plate 1202 in conjunction with the sliding groove 9, until the pressing plate 1303 is located above the top plate 1202. Then, the pressing knob 1304 is rotated, and the telescopic guide rod 1305 is used to move the pressing plate 1303 down to abut against the top plate 1202. This will work with the sealing gasket 1203 at the bottom of the top plate 1202 to improve the sealing performance of the insertion groove 8 and effectively prevent solution leakage at the insertion groove 8. The same principle applies to disassembly; the above operations are repeated in reverse.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
