Description

Technical Field

[0001] This utility model relates to the field of electrowinning equipment technology, and in particular to an electrowinning nickel and cobalt separator frame. Background Technology

[0002] Nickel- and cobalt-ion battery separators are key components used in battery manufacturing. They are used to separate the electrodes in nickel- and cobalt-ion batteries, respectively. They are mainly made of insulating materials and have excellent chemical stability and mechanical strength. They can effectively prevent electrode short circuits while allowing ions to pass through, thereby ensuring the normal operation of the battery and extending its service life.

[0003] The quality of electrolytic nickel and cobalt depends on both the electrolysis parameters and the structure and stability of the diaphragm frame. A reasonable diaphragm frame structure can ensure unobstructed communication between the electric lines in the anode and cathode regions, while the stability of the diaphragm frame can prevent the diaphragm bags from repeatedly sticking together during electrolysis.

[0004] The existing method of installing diaphragm frames has obvious shortcomings: operators need to thread the diaphragm frame pieces one by one onto the outside of the metal rod, and adjust and determine the interval between the anode and cathode areas using a spacer sleeve. This method of threading the sleeve one by one is not only time-consuming and labor-intensive, but also requires manual support to prevent it from tipping over after each diaphragm frame is installed before the next diaphragm frame can be installed. This series of cumbersome steps seriously affects the efficiency of operation and has become a bottleneck problem restricting the production process. Utility Model Content

[0005] One objective of this invention is to provide an electrolytic nickel and electrolytic cobalt diaphragm frame. This invention addresses the significant shortcomings of existing diaphragm frame installation methods mentioned in the background above: operators must thread the diaphragm frame pieces one by one onto the outside of the metal rod, and adjust and determine the interval between the anode and cathode areas using a spacer sleeve. This method of threading the sleeve one by one is not only time-consuming and labor-intensive, but also requires manual support to prevent tipping after each diaphragm frame is installed before the next diaphragm frame can be installed. This series of cumbersome steps seriously affects the efficiency of the operation.

[0006] An electrolytic nickel-cobalt separator frame according to an embodiment of the present invention includes:

[0007] The diaphragm frame mechanism includes a large diaphragm frame piece and a small diaphragm frame piece. Both the large and small diaphragm frame pieces have slots on their outer sides for engaging with metal rods. The large and small diaphragm frame pieces are fixed to fasteners via metal rods. An anode area and a cathode area are formed between adjacent large and small diaphragm frame pieces. The small diaphragm frame pieces are rotatably connected to the large diaphragm frame piece via a rotating assembly.

[0008] A positioning mechanism is installed on the top of the large and small diaphragm frame pieces in the diaphragm frame mechanism to position the large and small diaphragm frame pieces. The positioning mechanism includes a rotating plate rotatably mounted on the top of the small diaphragm frame piece via a second rotating shaft. A support plate is fixedly mounted at the end between the two rotating plates. A screw is rotatably mounted inside the support plate. A spacer sleeve is fixedly mounted on the outer side of the screw near the large diaphragm frame piece. A stop is fixedly mounted on the side of the support plate near the small diaphragm frame piece.

[0009] Preferably, the slot group includes a transverse slot at the top of the diaphragm frame large piece and a support slot at the lower inner end, and an upper slot at the top and a lower slot at the bottom of the diaphragm frame small piece. The slot group is symmetrically opened at both outer ends of the diaphragm frame large piece and the diaphragm frame small piece.

[0010] Preferably, both the large and small diaphragm frame pieces are made of fiberglass, and the upper part of both the large and small diaphragm frame pieces has a serrated structure to ensure that the electric field lines are better transmitted to the cathode chamber during electrolysis.

[0011] Preferably, the fastener is a nut.

[0012] Preferably, an anode plate and a cathode plate are installed inside the anode region and the cathode region, respectively.

[0013] Preferably, the rotating assembly includes a rotating seat fixedly disposed below the large diaphragm frame piece and a connecting plate fixedly disposed below the small diaphragm frame piece. The rotating seat has a plurality of adjustable perforations horizontally opened inside. The small diaphragm frame piece and the connecting plate are rotatably disposed through the adjustable perforations inside the rotating seat via a first rotating shaft, so as to adjust the distance between the small diaphragm frame piece and the large diaphragm frame piece by changing the position of the first rotating shaft inside the adjustable perforations.

[0014] Preferably, a knob is fixedly provided at the other end of the screw.

[0015] Preferably, the metal rod is made of titanium alloy, with threaded ends, and is resistant to acid corrosion.

[0016] The beneficial effects of this utility model are:

[0017] This invention effectively avoids the problem of inserting each piece of the diaphragm frame piece by piece in the traditional method by setting up a diaphragm frame mechanism. The diaphragm frame mechanism achieves rapid assembly through the cooperation of the slot group and the metal rod. In use, the slot group on the outside of the large and small diaphragm frame pieces includes a horizontal slot, a support slot, an upper slot, and a lower slot. Operators can quickly snap the diaphragm frame pieces to the metal rod. Furthermore, the large and small diaphragm frame pieces are connected by a rotating component, so that they do not need to be inserted one by one during assembly, thus effectively avoiding the time-consuming and laborious drawbacks of the traditional installation method. In addition, the adjustable perforation of the rotating seat in the rotating component is linked to the adapter plate through the first rotating shaft. During installation, by adjusting the horizontal position of the rotating shaft in the perforation, the distance between the small and large diaphragm frame pieces can be changed to form a standardized anode and cathode area interval. Therefore, this structure not only makes the installation process simpler but also greatly reduces the inconvenience of installation and effectively avoids the problem of low work efficiency.

[0018] This invention effectively avoids the problem of manual support to prevent tipping by setting up a positioning mechanism. The positioning mechanism forms a rigid triangular support structure with the rotating plate and the support plate. During operation, the rotating screw drives the spacer sleeve to move axially. When the end face of the spacer sleeve abuts against the large diaphragm frame piece, the abutment on the other side of the support plate simultaneously presses against the small diaphragm frame piece, forming a two-way positioning lock. In conjunction with the rotating component provided between the large and small diaphragm frame pieces, the distance between the anode and cathode areas between the large and small diaphragm frame pieces can be changed. This effectively avoids the cumbersome steps of adjusting the interval through the spacer sleeve in the traditional installation method, reduces installation time and labor costs, and makes the installation of the diaphragm frame fast, accurate and safe.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] refer to Figure 1-4 An electrolytic nickel-cobalt diaphragm frame, comprising:

[0027] The diaphragm frame mechanism 1 includes a large diaphragm frame piece 101 and a small diaphragm frame piece 102. Both the large diaphragm frame piece 101 and the small diaphragm frame piece 102 have slots on their outer sides for engaging with a metal rod 107. Each slot includes a transverse slot 103 at the top of the large diaphragm frame piece 101 and a support slot 104 at its lower inner end, and an upper slot 105 at the top and a lower slot 106 at the bottom of the small diaphragm frame piece 102. These slots are symmetrically arranged on the outer sides of both the large diaphragm frame piece 101 and the small diaphragm frame piece 102. At the end, the large diaphragm frame piece 101 and the small diaphragm frame piece 102 are fixed to the fastener 108 by a metal through rod 107. Between adjacent large diaphragm frame pieces 101 and small diaphragm frame pieces 102, an anode region 109 and a cathode region 110 are formed. The small diaphragm frame piece 102 is rotatably connected to the large diaphragm frame piece 101 via a rotating assembly. The rotating assembly includes a rotating seat 112 fixedly disposed below the large diaphragm frame piece 101 and a transition plate 114 fixedly disposed below the small diaphragm frame piece 102. The interior of the base 112 has several adjustable perforations 113. The diaphragm frame piece 102 and the adapter plate 114 are rotatably connected to the adjustable perforations 113 inside the rotating base 112 via a first rotating shaft 115. This allows the spacing between the diaphragm frame piece 102 and the diaphragm frame piece 101 to be adjusted by changing the position of the first rotating shaft 115 inside the adjustable perforations 113. The outer sides of the diaphragm frame piece 101 and the diaphragm frame piece 102 have a set of slots, including a transverse slot, a support slot, an upper slot, and a lower slot. Operators can quickly snap the diaphragm frame pieces to the metal rods, and the large and small diaphragm frame pieces are connected by a rotating assembly, eliminating the need to thread them one by one during assembly. This effectively avoids the time-consuming and labor-intensive drawbacks of traditional installation methods. In addition, the adjustable perforation of the rotating seat in the rotating assembly is linked to the adapter plate through the first rotating shaft. During installation, by adjusting the horizontal position of the rotating shaft in the perforation, the spacing between the small and large diaphragm frame pieces can be changed, forming a standardized anode and cathode area spacing.

[0028] Positioning mechanism 2 is installed on the top of the diaphragm frame large piece 101 and diaphragm frame small piece 102 in diaphragm frame mechanism 1. It is used to position the diaphragm frame large piece 101 and diaphragm frame small piece 102. Positioning mechanism 2 includes a rotating plate 201 rotatably mounted on the top of diaphragm frame small piece 102 via a second rotating shaft 202. A support plate 203 is fixedly mounted at the end between the two rotating plates 201. A screw 205 is rotatably mounted inside the support plate 203. A spacer sleeve 206 is fixedly mounted on the outer side of the screw 205 near the diaphragm frame large piece 101. A stop seat 204 is fixedly mounted on the side of the support plate 203 near the diaphragm frame small piece 102. The positioning mechanism forms a rigid triangular support structure through the rotating plate and the support plate. During operation, rotating the screw drives the spacer sleeve to move axially. When the end face of the spacer sleeve abuts against the diaphragm frame large piece, the stop seat on the other side of the support plate simultaneously presses against the diaphragm frame small piece, forming a bidirectional positioning lock.

[0029] Example 1: Both the large diaphragm frame 101 and the small diaphragm frame 102 are made of fiberglass, ensuring the strength and corrosion resistance of the structure. The upper part of both the large diaphragm frame 101 and the small diaphragm frame 102 has a serrated structure, which ensures that the electric field lines are better transmitted to the cathode chamber during electrolysis. The fastener 108 is a nut. The anode plate and cathode plate are installed in the anode area 109 and the cathode area 110 respectively, realizing the high efficiency of the electrolysis process.

[0030] Example 2: A knob 207 is fixedly installed at the other end of the screw 205. By rotating the knob, the distance between the large diaphragm frame piece 101 and the small diaphragm frame piece 102 can be changed. The metal rod 107 is made of titanium alloy and has a threaded structure at both ends, making it resistant to acid corrosion.

[0031] Working principle: First, the diaphragm frame mechanism 1 includes a large diaphragm frame piece 101 and a small diaphragm frame piece 102 made of fiberglass. Both have a serrated structure on the upper part, which helps the electric field lines to be transmitted to the cathode chamber more efficiently during electrolysis. The outer sides of the large diaphragm frame piece 101 and the small diaphragm frame piece 102 are symmetrically provided with a set of slots, including a transverse slot 103, a support slot 104, an upper slot 105, and a lower slot 106, which facilitates quick engagement with the metal rod 107. Next, the large diaphragm frame piece 101 and the small diaphragm frame piece 102 are fixed by the metal rod 107 and the nut fastener 108, forming an anode area 109 and a cathode area 110, which are respectively installed with an anode plate and a cathode plate to ensure the efficient operation of the electrolysis process. In addition, the small diaphragm frame piece 102 is rotatably connected to the large diaphragm frame piece 101 through a rotating assembly, which includes a rotating seat. 112. The adapter plate 114 and the first rotating shaft 115 can change the distance between the diaphragm frame small piece 102 and the diaphragm frame large piece 101 by adjusting the position of the first rotating shaft in the adjustable perforation 113, so as to achieve a standardized anode and cathode area spacing. Finally, the positioning mechanism 2 is installed on the top of the diaphragm frame large piece 101 and the diaphragm frame small piece 102, including a rotating plate 201, a support plate 203, a screw 205, a spacer sleeve 206 and a stop 204. By rotating the knob 207, the screw 205 is moved so that the spacer sleeve 206 abuts against the diaphragm frame large piece 101, and at the same time the stop 204 presses the diaphragm frame small piece 102 to form a two-way positioning lock, so as to ensure the stability and installation accuracy of the diaphragm frame. The metal through rod 107 is made of titanium alloy and has a threaded structure at both ends, which is resistant to acid corrosion and further improves the overall performance and durability of the diaphragm frame.
