Description

Technical Field

[0001] The utility model relates to the technical field of cobalt sulfate recovery and treatment, in particular to a cobalt sulfate solution impurity removal and recovery device. Background Art

[0002] Cobalt sulfate is widely used in industry. It can act as a medium-strength sulfur-replacing solvent in the electroplating process. It is most commonly used in the electrolysis of di- and tri-sulfur. It is beneficial for capturing small cations and is also convenient for recovering residual sulfiding agents.

[0003] In practical applications, cobalt sulfate is often used in the form of a solution (such as in electroplating processes). In order to avoid waste, the cobalt sulfate solution is recycled after use. One of the main purposes of recycling is to filter and remove impurities from the solution. However, the existing cobalt sulfate solution impurity removal and recovery device has a relatively simple structure. During use, the filter screen is often blocked by impurities, thereby reducing the filtration and recovery efficiency. In order to cope with this situation, the filter screen needs to be cleaned or disassembled and replaced manually during use, which is time-consuming and increases labor costs, further reducing the cobalt sulfate impurity removal and recovery efficiency. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the name of the utility model of this application to avoid blurring the purpose of this section, the abstract of the specification and the name of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Figure 1-Figure 4 The utility model shows a schematic diagram of the entire structure of a cobalt sulfate solution impurity removal and recovery device. Figure 1-Figure 4 A cobalt sulfate solution impurity removal and recovery device according to the present embodiment includes a treatment box 100, and filter screens 200 are arranged on both sides of the central axis of the treatment box 100, and the filter screens 200 divide the inner cavity of the treatment box 100 into three cavity sections. The areas opposite to the two filter screens 200 are the filter cavity 110, and the middle area of ​​the two filter screens 200 is the purification cavity 120. A water inlet cabin 400 connected to the filter cavity 110 is arranged on the top of the treatment box 100, and a hollow plate 300 parallel to the filter screen 200 is arranged in the center of the purification cavity 120. A plurality of high-pressure scattering nozzles 310 are respectively arranged on both sides of the hollow plate 300 facing the filter screen 200, and a high-pressure water pipe 330 connected to the hollow plate 300 is also arranged on the outside of the treatment box 100. A drainage pipe 500 connected to the purification cavity 120 and a sewage valve 600 connected to the filter cavity 110 are arranged at the bottom of the treatment box 100.

[0024] A maintenance door 150 corresponding to the filter 200 is also provided on one side of the processing box 100, and a support leg 160 is also provided at the bottom of the processing box 100. It can be understood that by opening the maintenance door 150, the staff can conveniently replace and maintain the filter 200 and the hollow plate 300, and the support leg 160 can be used to vertically stabilize the processing box 100 and the entire device.

[0025] Two sets of positioning grooves 140 are provided at the upper and lower ends of the inner side of the processing box 100; the filter 200 includes an outer frame 210 that is matched and inserted into the inner side of the positioning grooves 140, a filter plate 220 fixed to the inner side of the outer frame 210, and reinforcing ribs 230 installed on both sides of the outer frame 210 and covering the filter plate 220. When in use, when the filter 200 needs to be installed, it is only necessary to open the inspection door 150 and directly insert the filter 200 into the positioning grooves 140, and a sealing ring may also be provided on the outer peripheral side of the outer frame 210 to prevent the liquid in the filter cavity 110 from infiltrating into the purification cavity 120 without being filtered; in addition, the reinforcing ribs 230 provided can form a stable support for the entire filter plate 220 to prevent deformation during flushing and use, and the reinforcing ribs 230 and the filter plate 220 and the outer frame 210 are all detachable structures for subsequent disassembly and replacement.

[0026] The top of the hollow plate 300 is also provided with a connection nozzle 320 connected to the high-pressure water pipe 330. The high-pressure water pipe 330 is also provided with a pressure pump 340. Here, one end of the high-pressure water pipe 330 away from the connection nozzle 320 is connected to the clean water source. When in use, the high-pressure water pipe 330 can inject high-pressure water into the hollow plate 300 under the action of the pressure pump 340. Under the action of pressure, the water in the hollow plate 300 can form a covering flushing to the filter screen 310 on both sides through the high-pressure scattering nozzle 310. Since impurities are mainly blocked on the sieve surface of the filter screen 310, the impurities are quickly separated from the mesh of the filter screen 310 under reverse flushing and high pressure push, so that the cleaned sewage is gathered in the filter chamber 110, and the sewage and impurities are discharged by opening the sewage valve 600, which effectively solves the problem that the filter screen is often blocked in the existing cobalt sulfate solution impurity removal and recovery device, and the time consumption and labor cost caused by manual cleaning are effectively solved, and the cobalt sulfate solution impurity removal and recovery efficiency is further improved.

[0027] Furthermore, both sides of the top of the treatment box 100 are provided with liquid inlets 130 connected to the water inlet tank 400, and the top of the water inlet tank 400 is also provided with a water injection port 410. Here, the water inlet tank 400 is equivalent to a cobalt sulfate stock solution transfer station. The unfiltered cobalt sulfate solution is introduced into the water inlet tank 400 through the water injection port 410, and the solution is naturally diverted to the filter chamber 110 on both sides through the water inlet tank 400 and the liquid inlet 130, and enters the purification chamber 120 after natural filtration through the filter screen 200.

[0028] Furthermore, a solenoid valve 510 is also provided on the drain pipe 500; wherein, a controller is also provided on the outside of the processing box 100, which is respectively connected to the signals of the solenoid valve 510, the drain valve 600 and the pressure pump 340. It can be understood that the cobalt sulfate solution impurity removal and recovery device is more convenient to use through the controller. It should be noted that when the filter 200 is flushed, the solenoid valve 510 is in a closed state and the drain valve 600 is in an open state.

[0029] In summary, in a cobalt sulfate solution impurity removal and recovery device of the present embodiment, when the filter screen 200 needs to be cleaned, the high-pressure water pipe 330 can inject high-pressure water into the hollow plate 300 under the action of the pressure pump 340. Under the action of pressure, the water in the hollow plate 300 can form a covering flushing to the filter screens 310 on both sides through the high-pressure scattering nozzle 310. Since impurities are mainly blocked on the screening surface of the filter screen 310, the impurities are quickly separated from the mesh of the filter screen 310 under reverse flushing and high pressure push, so that the cleaned sewage is gathered in the filter chamber 110, and the sewage and impurities are discharged by opening the drain valve 600, which effectively solves the problems of frequent filter screen blockage and the time consumption and labor cost caused by manual cleaning in the existing cobalt sulfate solution impurity removal and recovery device, and further improves the cobalt sulfate solution impurity removal and recovery efficiency.
