A high-efficiency and energy-saving preparation device for manganese electrolytic cathode plates

Abstract

This utility model belongs to the field of electrolytic manganese technology, specifically a high-efficiency and energy-saving preparation device for manganese electrolytic cathode plates. It includes a cathode plate surface, with a conductive sleeve pressed onto the upper end of the cathode plate surface. A pre-installation mechanism for pre-installing the conductive sleeve is installed on the cathode plate surface. Both the cathode plate surface and the conductive sleeve have two threaded holes. This utility model has a reasonable structure. Rotating the connecting circular plate causes the first bolt to rotate and move, driving the pressure plate downwards within the fixed groove, pressing the wire cable tightly against the bottom of the groove.

Description

Technical Field

[0001] This utility model belongs to the field of electrolytic manganese technology, specifically a high-efficiency and energy-saving preparation device for manganese electrolytic cathode plates. Background Technology

[0002] Manganese and manganese alloys are essential raw materials for industries such as steel, aluminum alloys, magnetic materials, and chemicals. There are two main methods for refining metallic manganese: thermal and electrolytic methods. The thermal method produces metallic manganese with a purity of no more than 95%-98%, while the electrolytic method can produce high-purity metallic manganese with a purity of over 99.7%-99.9%. The preparation process of electrolytic metallic manganese involves first leaching manganese ore with acid to obtain manganese salts, which are then fed into an electrolytic cell. Through electrolysis, manganese ions are deposited on the cathode plate, ultimately yielding elemental metallic manganese. The cathode plate, as the conductive cathode in manganese electrolysis, is an indispensable and crucial component in the electrolysis process.

[0003] Currently, various methods have been proposed for the preparation of a high-efficiency and energy-saving cathode plate for manganese electrolysis. For example, a patent application with publication number "CN217378049U" discloses an energy-saving cathode plate for electrolytic manganese. After the fastening and positioning are completed, the workers use welding to reinforce the mating ends of the conductive beam and the conductive sleeve, assembling them into a solid integrated structure. Further, when connecting the cathode plate and the conductive cable, the workers insert the exposed end of the conductive cable through the wire groove and simultaneously wind the cable around the bottom of the tightening bolt. Then, the workers tighten the clamping sleeve, causing it to spiral down on the tightening bolt to further tighten and position the conductive cable. However, the exposed end of the cable is spirally pressed down by the clamping sleeve, and the threads between the tightening bolt and the clamping sleeve will squeeze the exposed end of the cable, which may lead to conductor deformation, breakage, or insulation damage. This will not only directly affect the mechanical properties of the conductive cable itself but also reduce its service life and increase the frequency and cost of cable replacement.

[0004] Therefore, this utility model provides a high-efficiency and energy-saving preparation device for manganese electrolytic cathode plates. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A high-efficiency and energy-saving preparation device for manganese electrolysis cathode plates, comprising a cathode plate surface, a conductive sleeve pressed onto the upper end of the cathode plate surface, a pre-installation mechanism for pre-installing the conductive sleeve installed on the cathode plate surface, two threaded holes on both the cathode plate surface and the conductive sleeve, a groove on the conductive sleeve, two second bolts threadedly connected to the upper end of the conductive sleeve, the second bolts corresponding to the threaded holes, a knob fixedly connected to the upper end of the second bolt, a connecting block fixedly connected to the upper end of the knob, a first bolt threadedly connected to the connecting block, the first bolt passing through the rotating connecting block, a fixing groove on the connecting block, a connecting circular plate fixedly connected to one end of the first bolt, and a pressure plate rotatably connected to the other end of the first bolt, the pressure plate sliding within the fixing groove, and a protection mechanism for protecting electrical cables installed on the pressure plate.

[0007] Preferably, the pre-installation mechanism includes a rectangular block and two sliding plates. The rectangular block is fixedly installed on the upper end of the cathode plate. A rectangular groove is provided in the rectangular block, and the rectangular block slides in the groove. The two sliding plates slide in the rectangular groove. A limiting mechanism for limiting the sliding plates is installed in the rectangular groove, and a resetting mechanism for resetting the sliding plates is installed in the rectangular groove.

[0008] Preferably, the limiting mechanism includes two sliders, which are fixedly installed on opposite side walls of the slide plate. The rectangular groove has grooves on opposite inner walls, and the sliders slide within adjacent grooves.

[0009] Preferably, the reset mechanism includes a spring and a fixing plate, the fixing plate is fixedly installed in a rectangular groove, the spring is fixedly installed on the fixing plate, and the two ends of the spring are fixedly connected to the adjacent sliding plate.

[0010] Preferably, the protection mechanism includes a protection plate, which is fixedly installed on the side wall of the pressure plate and slides against the surface of the connecting block.

[0011] Preferably, a cable groove is provided at the lower end of the protection plate, and the inner wall of the cable groove is made of rubber.

[0012] Preferably, the connecting block is silver-plated.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The high-efficiency and energy-saving preparation device for manganese electrolytic cathode plates described in this utility model involves rotating a connecting circular plate, which drives a first bolt to rotate. The first bolt moves as it rotates, causing a pressure plate to move downwards within a fixed groove. This presses the electrical cable at the bottom of the groove, preventing pressure on the exposed end of the cable during thread rotation. This reduces the risk of conductor deformation, breakage, and insulation damage, thereby improving the mechanical properties and service life of the electrical cable and reducing replacement frequency and cost.

[0015] 2. The high-efficiency and energy-saving preparation device for manganese electrolysis cathode plates described in this utility model involves fitting a conductive sleeve onto the cathode plate surface. As the conductive sleeve moves downward, the sliding plate is pressed into the rectangular groove by the side wall of the groove. At this time, the spring is compressed. After the rectangular block passes through the groove, the side wall of the groove no longer presses the sliding plate, and the compressed spring instantly resets, causing the sliding plate to extend at the upper end of the conductive sleeve. This achieves the effect of pre-installing the conductive sleeve, preparing for the subsequent threaded connection of the conductive sleeve and the cathode plate surface by rotating the second bolt. This ensures the accuracy and reliability of the connection and prevents the cathode plate surface from shifting away from the conductive sleeve when rotating the second bolt.

[0024] 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.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 6 As shown in the embodiment of this utility model, a high-efficiency and energy-saving preparation device for manganese electrolysis cathode plates includes a cathode plate surface 1. A conductive sleeve 2 is pressed onto the upper end of the cathode plate surface 1. A pre-installation mechanism for pre-installing the conductive sleeve 2 is installed on the cathode plate surface 1. Both the cathode plate surface 1 and the conductive sleeve 2 have two threaded holes 8. A groove 9 is provided on the conductive sleeve 2. Two second bolts 15 are threadedly connected to the upper end of the conductive sleeve 2. The second bolts 15 correspond to the threaded holes 8. A knob 7 is fixedly connected to the upper end of the second bolts 15. A connecting block 5 is fixedly connected to the upper end of the knob 7. A first bolt 14 is threaded through a rotating connecting block 5. A fixing groove 19 is provided on the connecting block 5. A connecting circular plate 6 is fixedly connected to one end of the first bolt 14, and a pressure plate 20 is rotatably connected to the other end of the first bolt 14. The pressure plate 20 slides in the fixing groove 19. It should be noted that the inner wall of the fixing groove 19 limits the pressure plate 20 to prevent the pressure plate 20 from shifting when moving. Since the pressure plate 20 is rotatably connected to the first bolt 14, the rotation of the first bolt 14 will not drive the pressure plate 20 to rotate, but the movement of the first bolt 14 will drive the pressure plate 20 to move.

[0027] The pressure plate 20 is equipped with a protective mechanism for protecting the electrical cables. During operation, the knob 7 is turned, which drives the second bolt 15 to rotate, thereby causing the second bolt 15 to thread the cathode plate 1 and the conductive sleeve 2 through the threaded hole 8. The workers use welding to reinforce the mating ends of the conductive beam and the conductive sleeve 2, so that they are assembled into a solid integrated structure, ensuring the integrity and stability of the cathode plate.

[0028] like Figure 1 and Figure 3As shown, the pre-installation mechanism includes a rectangular block 3 and two sliding plates 4. The rectangular block 3 is fixedly installed on the upper end of the cathode plate surface 1. A rectangular groove 16 is formed in the rectangular block 3, which slides within the groove 9. The two sliding plates 4 slide within the rectangular groove 16. A limiting mechanism for limiting the sliding plates 4 is installed within the rectangular groove 16, and a resetting mechanism for resetting the sliding plates 4 is also installed within the rectangular groove 16. This structure allows for rapid pre-installation of the conductive sleeve 2 on the cathode plate surface 1. By utilizing the sliding of the rectangular block 3 within the groove 9, and with the aid of the limiting and resetting mechanisms, the sliding plates 4 automatically reset and extend after being compressed. This process eliminates the need for precise manual operation, greatly improving the efficiency and accuracy of pre-assembly and saving time for subsequent installation procedures.

[0029] like Figure 3 and Figure 5 As shown, the limiting mechanism includes two sliders 11, which are fixedly installed on opposite side walls of the slide plate 4. The rectangular groove 16 has grooves 17 formed on its inner walls, and the sliders 11 slide within adjacent grooves 17. This structure limits the range of motion of the slide plate 4, enhancing the reliability and stability of the entire pre-installation mechanism and preventing component damage or connection failures that may result from disordered movement of the slide plate 4.

[0030] like Figure 3 and Figure 5 As shown, the reset mechanism includes a spring 12 and a fixing plate 13. The fixing plate 13 is fixedly installed in the rectangular groove 16, and the spring 12 is fixedly installed on the fixing plate 13. Both ends of the spring 12 are fixedly connected to the adjacent slide plate 4. During operation, when the conductive sleeve 2 moves down, the slide plate 4 is pressed into the rectangular groove 16 by the side wall of the groove 9, and the spring 12 is compressed. When the rectangular block 3 passes through the groove 9, the side wall of the groove 9 no longer presses the slide plate 4, and the compressed spring 12 instantly resets, causing the slide plate 4 to extend at the upper end of the conductive sleeve 2. Through the above structure, the combination of the spring 12 and the fixing plate 13 allows the slide plate 4 to instantly reset when it is not compressed, without manual intervention, thus improving the automation and efficiency of the pre-installation process.

[0031] like Figure 4 and Figure 6 As shown, the protection mechanism includes a protection plate 18, which is fixedly installed on the side wall of the pressure plate 20. The protection plate 18 slides against the surface of the connecting block 5. During operation, as the pressure plate 20 moves downward, it also moves the protection plate 18 downward, thereby closing the fixing groove 19. Through this structure, the protection plate 18 slides against the surface of the connecting block 5, effectively preventing external substances such as electrolyte and impurities from entering through the gap between the connecting block 5 and the pressure plate 20 and corroding the exposed end of the cable, thus improving the service life of the cable and the reliability of the connection.

[0032] like Figure 6 As shown, a cable trough 10 is provided at the lower end of the protective plate 18, and the inner wall of the cable trough 10 is made of rubber. Through this structure, the cable trough 10, made of rubber, has a certain degree of elasticity and can adapt to cables of different diameters and specifications. Regardless of the thickness of the cable, the cable trough 10 can tightly fit the cable through its own elastic deformation, enhancing the device's versatility and flexibility for cables of different specifications.

[0033] like Figure 1 and Figure 4 As shown, the connecting block 5 is silver-plated. Through this structure, the silver layer has excellent anti-oxidation properties, which can prevent surface oxidation of the connecting block 5 to a certain extent, maintain the stability of its conductivity, and help improve the efficiency and quality of the electrolysis process.

[0034] Working principle: The rectangular block 3 slides within the groove 9 on the conductive sleeve 2. The movement range of the slide plate 4 is limited by the limiting mechanism slider 11 and slide groove 17, ensuring that the slide plate 4 slides orderly within the rectangular groove 16 of the rectangular block 3. When the conductive sleeve 2 moves downward, the slide plate 4 is pressed into the rectangular groove 16 by the side wall of the groove 9, and the spring 12 is compressed. After the rectangular block 3 passes through the groove 9, the side wall of the groove 9 no longer presses against the slide plate 4, and the compressed spring 12 instantly resets, causing the slide plate 4 to extend at the upper end of the conductive sleeve 2, thereby achieving the pre-installation effect of the conductive sleeve 2.

[0035] After pre-installation, turn knob 7. Knob 7 drives the second bolt 15 to rotate, which in turn causes the second bolt 15 to thread the cathode plate 1 and the conductive sleeve 2 through the threaded hole 8. Then, the workers use welding to reinforce the mating ends of the conductive beam and the conductive sleeve 2, so that they are assembled into a solid integrated structure, ensuring the integrity and stability of the cathode plate.

[0036] Rotating knob 7 causes the first bolt 14 to rotate. As the first bolt 14 rotates, it moves, causing the pressure plate 20 to move downwards within the fixing groove 19 on the connecting block 5. This presses the cable into the bottom of the fixing groove 19, preventing the exposed end of the cable from being squeezed by the screw threads. Simultaneously, the pressure plate 20 moves the protective plate 18 downwards, sealing the fixing groove 19. The protective plate 18 and cable trough 10 effectively protect the cable. The protective plate 18 slides against the surface of the connecting block 5, and the cable trough 10 at its lower end is made of rubber, ensuring a tight fit with the cable and preventing electrolyte or other corrosive substances from eroding the exposed end of the cable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
