Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrode foil manufacturing, and more specifically, to an electrode foil electrolytic cell apparatus. Background Technology
[0002] During the production of electrode foil, the electrode foil is formed in an electrolytic cell containing electrolyte. The electrolyte needs to be circulated in the electrolytic cell. The purpose of this circulation is to use a circulation pump to circulate the electrolyte in the electrolytic cell to maintain the electrolyte temperature and concentration uniformity. During the formation process, crystals, i.e., impurity particles, will be generated on the electrode foil. The extrusion of the electrode foil with crystals or impurity particles will damage the appearance quality of the electrode foil, causing pits or cracks. In severe cases, foil breakage will occur, affecting the appearance quality of the electrode foil product and reducing the yield and pass rate of the product.
[0003] The existing method to solve the problem of impurity particles affecting foil quality is to install a filter in the electrolyte circulation path to filter out crystals and impurity particles in the electrolyte. However, this method requires production to be stopped and the filter to be cleaned and maintained every once in a while, which will significantly increase production costs and reduce production efficiency.
[0004] Existing technology discloses an electrolytic cell apparatus for electrode foil formation, including an electrolytic cell body with a circulation inlet and a circulation outlet connected by a circulation pipe. The circulation outlet is located at the upper part of the electrolytic cell body, and an impurity precipitation device is located at the bottom of the electrolytic cell body. The precipitation device is connected to the electrolytic cell body to form a connected cavity. The precipitation device is funnel-shaped with a wider upper opening and a narrower lower opening, and a liquid outlet is located at the bottom of the precipitation device. This solution provides an electrolytic cell apparatus where the electrolyte used for formation can cause crystalline particles and impurities in the electrolyte to precipitate at the bottom of the conical electrolytic cell body. This effectively reduces the number of crystalline particles and impurities in the circulating electrolyte, improves the appearance quality of the aluminum foil during electrode foil formation, increases the product yield, extends the production cycle of electrode foil formation, and reduces production costs.
[0005] However, since the sedimentation device is directly installed at the bottom of the electrolytic cell and they are connected, when too much sediment accumulates in the sedimentation device and is not discharged in time, some impurity particles will be suspended in the electrolytic cell, which will also come into contact with the aluminum foil and affect the quality of the aluminum foil. Utility Model Content
[0006] The purpose of this invention is to overcome the problem that impurity particles easily accumulate in the existing electrolytic cells, causing damage to the quality of the foil. It provides an electrode foil electrolytic cell device that adds a precipitation chamber, separates the electrolytic chamber from the reaction chamber, and avoids impurity particles from affecting the quality of the foil in the electrolytic chamber.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0008] An electrode foil electrolytic cell device is provided, comprising an electrolytic cell body, a sedimentation tank, and a circulation tank. The electrolytic cell body has an electrolysis chamber inside and an outlet and an inlet respectively connected to the electrolysis chamber. The outlet is located at the bottom of the electrolytic cell body. The sedimentation tank has a sedimentation chamber inside, and the circulation tank has a circulation chamber inside. The sedimentation tank is located at the bottom of the electrolytic cell body. The outlet and sedimentation chamber are connected via a pipe. The sedimentation chamber is connected to a drain pipe equipped with a drain switch. The circulation tank is located above the sedimentation tank and on one side of the electrolytic cell body. The circulation chamber is connected to the inlet via a pipe. A driving mechanism is provided within the circulation tank to drive the electrolyte circulation.
[0009] This invention relates to an electrode foil electrolytic cell device. The aluminum foil undergoes a formation reaction within the electrolytic cell body under the traction of rollers. A driving mechanism circulates the electrolyte within the electrolytic chamber, ensuring uniform electrolyte temperature and concentration. During the electrolysis process within the electrolytic chamber, the electrode foil produces crystals and impurity particles. These impurity particles are carried by the circulating water flow from the outlet into the sedimentation chamber. Due to their weight, these particles settle at the bottom of the sedimentation chamber and move within it under the influence of the water flow, accumulating below the circulation tank. When the sediment accumulates to a certain extent... Staff can then open the drain switch, and the sediment will be discharged from the drain pipe along with some of the electrolyte. Compared to existing technologies, this electrolytic cell device has an added sedimentation chamber, where impurity particles can settle and accumulate below the circulation tank under the influence of water flow, instead of accumulating below the electrolytic cell. Impurity particles will not return to the electrolytic chamber through the outlet, thus preventing their accumulation and avoiding damage to the electrode foil. Furthermore, the drain switch can be opened periodically to remove the sediment, making it simpler and more convenient than using a filtration device.
[0010] Furthermore, the driving mechanism includes a first driving member fixed to the outer wall of the circulation tank, a stirring rod connected to the output end of the first driving member and located within the circulation chamber, and a plurality of spiral lifters disposed on the stirring rod. The first driving member can drive the stirring rod to rotate, thereby driving the spiral lifters to rotate and causing the electrolyte to rise, so that the electrolyte continuously circulates within the circulation channel, improving the uniformity of water quality. Using spiral lifters to stir the electrolyte improves the uniformity of water quality compared to the use of a circulation pump in the prior art. Since the stirring rod is only disposed within the stirring chamber and does not extend into the sedimentation chamber, the stirring rod will not agitate the sedimented impurities or lift them.
[0011] Furthermore, a baffle screen is horizontally installed on the inner wall of the sedimentation chamber, located below the circulation chamber. The baffle screen can block some lighter impurity particles, preventing them from entering the circulation chamber. These particles, once blocked, will fall to the bottom of the sedimentation tank under gravity. Therefore, fewer impurity particles remain on the baffle screen, and it does not need to be replaced.
[0012] Furthermore, the water inlet is located on the side wall of the electrolytic cell body, and there are several water inlets. Located on the side wall of the electrolytic cell body, the water inlet reduces energy consumption compared to its location on the top. The presence of multiple water inlets allows the electrolyte to enter the electrolysis chamber from different inlets, improving water quality uniformity.
[0013] Furthermore, a baffle is provided on the inner wall of the sedimentation chamber, located below the circulation tank. The baffle, together with the side wall and bottom surface of the sedimentation chamber, forms a drain chamber with an inlet. The drain pipe is connected to the drain chamber. Due to the action of the driving mechanism, the sediment at the bottom of the sedimentation chamber moves with the water flow and enters the drain chamber through the inlet. The inner wall of the drain chamber blocks impurity particles, collecting them within the drain chamber and preventing them from scattering. The drain pipe's connection to the drain chamber allows for centralized drainage, resulting in better drainage efficiency.
[0014] Furthermore, the sedimentation tank is also equipped with a flow-blocking mechanism, which includes a second driving component fixed to the outer wall of the circulation tank and a flow-blocking plate located inside the sedimentation chamber. The second driving component is used to drive the flow-blocking plate to block the inlet. Normally, the flow-blocking plate is in the open state, allowing impurities to enter the discharge chamber from the outlet. When discharge is desired, the second driving component can be controlled to close the flow-blocking plate, blocking the inlet, and then the discharge switch can be opened to discharge the impurities and sediment, reducing electrolyte waste.
[0015] Furthermore, the bottom of the sedimentation chamber is provided with an inclined section, with the higher end of the inclined section located at the bottom of the outlet and the lower end located at the inlet. Impurity particles, after falling into the sedimentation chamber, can enter the inlet along the inclined section, which provides guidance.
[0016] Furthermore, the circulation chamber is cylindrical. This reduces the energy loss due to the collision between the water flow and the inner wall of the circulation chamber, thus lowering energy consumption.
[0017] Furthermore, the sidewall of the electrolytic cell body is inclined towards the outlet to form a conical portion. If the bottom surface of the electrolytic cell body is flat, impurity particles tend to accumulate on the bottom surface. Even if some impurity particles enter the sedimentation chamber with the water flow, the remaining impurity particles remain on the bottom surface. By making the bottom of the electrolytic cell body conical, impurity particles can enter the sedimentation chamber from the outlet along the conical portion, reducing the residue of impurity particles in the electrolytic cell body.
[0018] Furthermore, the cone angle of the conical portion is 100°-120°. This angle range is neither too flat, causing excessive residue of impurity particles, nor too tilted, reducing the volume of the electrolytic cell body.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] 1. A sedimentation chamber has been added, which allows impurity particles to settle in the sedimentation chamber and accumulate below the circulation tank under the action of water flow, instead of accumulating below the electrolysis cell. Impurity particles will not return to the electrolysis chamber through the outlet, thus avoiding the accumulation of impurity particles in the electrolysis chamber and preventing impurity particles from squeezing and damaging the appearance of the electrode foil.
[0021] 2. Using a propeller to stir and circulate the electrolyte improves water quality uniformity compared to existing technologies that use circulation pumps;
[0022] 3. The baffle is designed so that impurities can enter the drain chamber from the inlet, and the inner wall of the drain chamber will block the impurities and collect them in the drain chamber, preventing them from scattering. The drain pipe is connected to the drain chamber, which allows for centralized drainage and better drainage effect.
[0023] 4. The side wall of the electrolytic cell body is inclined towards the outlet to form a conical part, so that impurity particles can enter the sedimentation chamber from the outlet along the conical part, reducing the residue of impurity particles in the electrolytic cell body.

[0031] An electrode foil electrolytic cell apparatus, such as Figure 1As shown, the system includes an electrolytic cell body 100, a sedimentation tank 200, and a circulation tank 300. The electrolytic cell body 100 has an electrolysis chamber 110 inside, and an outlet 120 at its bottom. Three inlets 130 are vertically arranged on the sidewalls of the electrolytic cell body 100. The sedimentation tank 200 has a sedimentation chamber 210 inside, and the circulation tank 300 has a circulation chamber 310 inside. The sedimentation tank 200 is located at the bottom of the electrolytic cell body 100. The outlet 120 is connected to the sedimentation chamber 210 via a pipe. The sedimentation chamber 210 is connected to a drain pipe 220, which is equipped with a drain switch 230. In this embodiment, the drain switch 230... 0 is an electrically controlled valve. The circulation tank 300 is located above the sedimentation tank 200 and on one side of the electrolytic cell body 100. The circulation chamber 310 is connected to the water inlet 130 through a pipe. A dirt-blocking net 240 is provided on the inner wall of the sedimentation chamber 210 in the horizontal direction. The dirt-blocking net 240 is located below the circulation chamber 310. A drive mechanism 400 is provided in the circulation tank 300. The drive mechanism 400 includes a first drive member 410 fixed outside the circulation tank 300, a stirring rod 420 connected to the output end of the first drive member 410 and located in the circulation chamber 310, and seven spiral lifters 430 provided on the stirring rod 420. In this embodiment, the first drive member 410 is a rotary motor.
[0032] The working principle of this embodiment is as follows:
[0033] This invention relates to an electrode foil electrolytic cell device. The aluminum foil undergoes a formation reaction within the electrolytic chamber 110 under the traction of rollers. A first driving component 410 drives a stirring rod 420 to rotate, which in turn rotates a propeller 430, causing the electrolyte to circulate and ensuring uniform temperature and concentration. During the electrolysis process within the electrolytic chamber 110, the electrode foil produces crystals and impurity particles. These impurity particles are carried by the circulating water flow from the outlet 120 into the sedimentation chamber 210. Due to their weight, these particles settle at the bottom of the sedimentation chamber 210 and move within it under the influence of the water flow, accumulating below the circulation tank 300. When the sediment accumulates to a certain extent... Once opened, the drain switch 230 will allow the sediment to be discharged from the drain pipe 220 along with some of the electrolyte. Compared to existing technologies, this electrolytic cell device adds a sedimentation chamber 210, where impurity particles can settle and accumulate below the circulation tank 300 under the influence of water flow, instead of accumulating below the electrolysis chamber 110. Excessive accumulation of impurity particles will not return to the electrolysis chamber 110 through the outlet 120, thus preventing the accumulation of impurity particles in the electrolysis chamber 110 and avoiding the squeezing and damage to the appearance of the electrode foil. At the same time, the drain switch 230 can be opened periodically to discharge the sediment, which is simpler and more convenient than using a filtration device.
[0034] The beneficial effects of this embodiment are as follows:
[0035] A sedimentation chamber 210 is added, allowing impurity particles to settle inside and preventing them from accumulating in the electrolysis chamber 110. This avoids the impurity particles from compressing and damaging the appearance of the aluminum foil. The drain switch 230 can be opened periodically to discharge the sediment, which is simpler and more convenient than using a filter device. A propeller 430 is used to stir the electrolyte, resulting in better water quality uniformity compared to the existing technology that uses a circulation pump. The filter screen 240 can block some of the lighter impurity particles, preventing them from entering the circulation chamber 310. After being blocked, these impurity particles will fall to the bottom of the sedimentation tank 200 under gravity. Therefore, there are fewer impurity particles remaining on the filter screen 240, and the filter screen 240 does not need to be replaced.

The baffle 250 is located below the circulation tank 300. The baffle 250, the side wall of the sedimentation chamber 210, and the bottom surface of the sedimentation chamber 210 form a sewage discharge chamber 270 with a sewage inlet 260. The sewage discharge pipe 220 is connected to the sewage discharge chamber 270. An inclined part 280 is provided at the bottom of the sedimentation chamber 210. The higher end of the inclined part 280 is located at... At the bottom of the outlet 120, the lower end of the inclined portion 280 is located at the inlet 260. The angle between the inclined portion 280 and the horizontal plane is 15°.

The second driving member 510 is a rotary driving member, and the baffle plate 520 is rotatably connected to the bottom of the sedimentation chamber 210. In this embodiment, the second driving member 510 is a rotary motor.
[0038] The working principle of this embodiment is as follows:
[0039] Due to the action of the drive mechanism 400, the sediment at the bottom of the sedimentation chamber 210 will also move with the water flow at the bottom of the sedimentation chamber 210. Under the guidance of the inclined part, it will enter the sewage discharge chamber 270 from the sewage inlet 260. The inner wall of the sewage discharge chamber 270 will block the impurity particles and collect them in the sewage discharge chamber 270 to prevent the impurity particles from scattering everywhere. The sewage discharge pipe 220 is connected to the sewage discharge chamber 270, which can centralize the sewage discharge and improve the sewage discharge effect. The baffle plate 520 is normally in the open state, and impurities can enter the sewage discharge chamber 270 from the sewage discharge outlet. When you want to discharge sewage, you can control the second drive component 510 to close the baffle plate 520 to block the sewage inlet 260, and then open the sewage discharge switch 230 to discharge the impurity sediment and reduce the waste of electrolyte.

[0044] The working principle of this embodiment is as follows:
[0045] The cylindrical circulation chamber 310 can reduce the energy loss caused by the collision between the water flow and the inner wall of the circulation chamber 310, thus reducing energy consumption.
