A device for removing defective zinc cathode plates

Abstract

This utility model belongs to the technical field of electrolytic zinc cathode plates, and particularly relates to a defective electrolytic zinc cathode plate removal device. It includes a support frame, a mounting plate disposed on one side of the support frame, and a fixing plate disposed on one side of the mounting plate. An adjustment mechanism is provided on one side of the mounting plate, and a disassembly mechanism is provided on one side of the fixing plate. This defective electrolytic zinc cathode plate removal device, through the adjustment mechanism, directly uses a drive chain in the transmission assembly to move the mounting plate up and down when removing defective electrolytic zinc cathode plates. When a defective plate needs to be removed, the mounting plate moves downwards. At this time, the defective plate removal shovel first contacts the stripping plate and scrapes it. Meanwhile, the support plate rotates around the connecting shaft, and the return spring is compressed. When scraping the surface of the stripping plate, the defective plate removal shovel moves along the top of the stripping plate, preventing irreversible wear on the surface during the removal of defective plates.

Description

Technical Field

[0001] This utility model relates to the field of electrolytic zinc cathode plate technology, specifically to a device for removing defective electrolytic zinc cathode plates. Background Technology

[0002] The electrolytic process for zinc hydrometallurgy involves the following steps: A purified zinc sulfate solution is fed into an electrolytic cell; lead-silver alloy anode plates and aluminum cathode plates are suspended inside the cell, and direct current is applied; after a period of electrowinning, a crane using a specialized lifting device lifts the cathode plates, which have accumulated a certain thickness of zinc layer, out of the electrolytic cell; the zinc layer is then peeled off the cathode plates manually or mechanically; the zinc sheets are stacked and transported by forklift to the casting plant to obtain the electrolytic zinc product; the cathode plates are then washed and lifted back into the electrolytic cell by the crane to begin the next electrowinning cycle. During the processing of the electrowinning zinc cathode plates on the zinc stripping machine, if a defective zinc cathode plate is detected, it needs to be detached from the machine's suspension chain.

[0003] Existing defective product removal devices for electrolytic zinc cathode plates typically use a defective product removal shovel to directly scrape off defective products from the surface of the stripping plate. However, the direct impact of the shovel can damage the stripping plate, and over time, stubborn stains may accumulate on its surface, which is difficult to remove. Traditional defective product removal shovels are also difficult to disassemble and clean.

[0004] Patent document CN211814674U3 discloses an automatic zinc stripping machine with a double-row receiving function. This machine features a reasonable structural layout and occupies a small area. It is equipped with two sets of receiving devices, solving the technical problem that existing zinc stripping units cannot receive two half-slot cathode plates at once. This significantly reduces the workload of the overhead crane during loading and unloading, improves the efficiency of the zinc stripping machine's receiving operation, and reduces the labor intensity of personnel.

[0005] However, the automatic zinc stripping machine with double-row receiving function does not have a disassembly device for the defective product removal shovel during use. Disassembling the defective product removal shovel is quite troublesome, making it difficult to clean and affecting subsequent work. Therefore, it is necessary to propose a defective product removal device for electrolytic zinc cathode plates. Utility Model Content

[0006] The purpose of this invention is to provide a device for removing defective electrolytic zinc cathode plates, so as to solve the problem of removing defective electrolytic zinc cathode plates mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a device for removing defective electrolytic zinc cathode plates, comprising a support frame, a mounting plate disposed on one side of the support frame, and a fixing plate disposed on one side of the mounting plate, wherein an adjustment mechanism is provided on one side of the mounting plate, and a disassembly mechanism is provided on one side of the fixing plate; The adjustment mechanism includes a side plate, a return spring, a support plate, a connecting shaft, a connecting rod, and a slider. The side plate is fixedly connected to the top of the mounting plate, the return spring is disposed on one side of the side plate, the connecting shaft is rotatably connected to one side of the mounting plate, the support plate is fixedly connected to the outside of the connecting shaft, the connecting rod is fixedly connected to the outside of the connecting shaft, and the slider is fixedly connected to the back of the mounting plate.

[0008] Preferably, each end of the reset spring is provided with a spring seat, which is fixedly connected to one side of the side plate and the support plate, respectively. The spring seat is mainly used to position and install the reset spring to prevent the reset spring from shifting its position when compressed.

[0009] Preferably, one end of the connecting rod is fixedly connected to the fixing plate. The connecting rod mainly serves as a support for the fixing plate. When the defective product is removed by the scraper, the angle of the connecting rod changes, thereby driving the support plate to compress the return spring.

[0010] Preferably, the disassembly mechanism includes a T-shaped plate, a defective product detachment shovel, a limiting plate, a baffle, a mounting block, an auxiliary spring, a telescopic rod, and a push plate. The T-shaped plate is slidably connected to one side of the fixed plate, the defective product detachment shovel is fixedly connected to one side of the T-shaped plate, the limiting plate and the mounting block are fixedly connected to one side of the fixed plate, the baffle is disposed on one side of the fixed plate, the telescopic rod is fixedly connected to the inner wall of the mounting block, the auxiliary spring is movably connected to the outside of the telescopic rod, and the push plate is fixedly connected to one side of the telescopic rod.

[0011] Preferably, a limiting screw is provided on one side of the baffle. There are two limiting screws, and the limiting screws connect the baffle to the fixing plate to fix the T-shaped plate.

[0012] Preferably, the limiting plate and the mounting block have a through groove on one side that cooperates with the T-shaped plate. On the one hand, the T-shaped plate can be limited to facilitate installation and disassembly. On the other hand, the through groove can cooperate with the baffle to fix the entire T-shaped plate, ensuring the stability of the defective product when it leaves the scraper and preventing the defective product from shaking when it leaves the scraper.

[0013] Preferably, a transmission assembly is provided on one side of the support frame, and a stripping plate is provided at the bottom of the support frame. The transmission assembly includes a drive chain, which mainly lifts and lowers the mounting plate, and then uses a defective product removal shovel to scrape off defective products from the surface of the stripping plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This defective electrolytic zinc cathode plate removal device, through an adjustable mechanism, directly uses the drive chain in the transmission assembly to move the mounting plate up and down when removing defective electrolytic zinc cathode plates. When a defective plate needs to be removed, the mounting plate moves down, at which point the defective plate removal shovel first contacts the stripping plate and scrapes it. At this time, the support plate rotates around the connecting shaft, and the return spring is compressed. When scraping the surface of the stripping plate, the defective plate removal shovel moves along the top of the stripping plate, and the scraping of the defective plate does not cause irreversible wear on its surface, resulting in good scraping effect.

[0015] 2. This defective product removal device for electrolytic zinc cathode plates, through a disassembly mechanism, allows for the removal of the defective product removal shovel by removing the fixing nut on one side of the baffle after the work is completed. At this time, the auxiliary spring, which is under compression, will generate a rebound force on one side of the push plate. The push plate pushes the T-shaped plate out of the inner wall of the limiting plate and the mounting block a certain distance, which facilitates the disassembly of the T-shaped plate and the cleaning of the defective product removal shovel. This avoids the difficulty in removing stains from the surface of the defective product removal shovel, which would affect subsequent work. Moreover, disassembly is simple and cleaning is relatively easy. Attached Figure Description

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 This utility model provides a technical solution: Example 1: A defective electrolytic zinc cathode plate removal device includes a support frame 1, a mounting plate 3 disposed on one side of the support frame 1, and a fixing plate 4 disposed on one side of the mounting plate 3. An adjustment mechanism is provided on one side of the mounting plate 3. The adjustment mechanism includes a side plate 301, a return spring 302, a support plate 303, a connecting shaft 304, a connecting rod 305, and a slider 306. The side plate 301 is fixedly connected to the top of the mounting plate 3. The return spring 302 is located on one side of the side plate 301, and each end of the return spring 302 has a spring seat, which is fixedly connected to one side of the side plate 301 and the support plate 303, respectively. The spring seats mainly position the return spring 302 to prevent it from shifting its position when compressed. The connecting shaft 304 is rotatably connected to one side of the mounting plate 3. The support plate 303 is fixedly connected to the outside of the connecting shaft 304. The connecting rod 305 is fixedly connected to the outside of the connecting shaft 304. Each end of the return spring 302 has a spring seat, which is fixedly connected to one side of the side plate 301 and the support plate 303, respectively. The spring seats mainly position the return spring 302 to prevent it from shifting its position when compressed. The slider 306 is fixedly connected to the back of the mounting plate 3. When removing defective electrolytic zinc cathode plates, the drive chain in the transmission assembly 2 directly drives the mounting plate 3 to move up and down to remove the defective electrolytic zinc cathode plates. When it is necessary to remove the defective products, the mounting plate 3 moves down. At this time, the defective product removal shovel 402 first contacts the stripping plate 5 and scrapes the stripping plate 5. At this time, the support plate 303 will rotate around the connecting shaft 304, and the return spring 302 will be compressed. When scraping the surface of the stripping plate 5, the defective product removal shovel 402 will change along the top of the stripping plate 5. When scraping the defective products, it will not cause irreversible wear on the surface.

[0020] Example 2: Based on Embodiment 1, a disassembly mechanism is provided on one side of the fixed plate 4. The disassembly mechanism includes a T-shaped plate 401, a defective product removal shovel 402, a limiting plate 403, a baffle 404, a mounting block 405, an auxiliary spring 406, a telescopic rod 407, and a push plate 408. The T-shaped plate 401 is slidably connected to one side of the fixed plate 4, the defective product removal shovel 402 is fixedly connected to one side of the T-shaped plate 401, and the limiting plate 403 and the mounting block 405 are fixedly connected to one side of the fixed plate 4. A through groove is provided on one side of the limiting plate 403 and the mounting block 405 to cooperate with the T-shaped plate 401. On the one hand, the T-shaped plate 401 can be limited to facilitate installation and disassembly. On the other hand, the through groove can cooperate with the baffle 404 to fix the entire T-shaped plate 401, ensuring the stability of the defective product removal shovel 402 and preventing the defective product removal shovel 402 from shaking during scraping. A baffle 404 is disposed on one side of the fixed plate 4. Two limit screws are provided on one side of the baffle 404, connecting the baffle 404 to the fixed plate 4 and fixing the T-shaped plate 401. A telescopic rod 407 is fixedly connected to the inner wall of the mounting block 405. An auxiliary spring 406 is movably connected to the outside of the telescopic rod 407. A push plate 408 is fixedly connected to one side of the telescopic rod 407. After the work is completed, some hard-to-remove stains may be attached to the surface of the defective product removal shovel 402, which may cause trouble for subsequent use. At this time, the defective product removal shovel 402 can be removed by removing the fixing nut on one side of the baffle 404. At this time, the auxiliary spring 406, which is in a compressed state, will generate a rebound force on one side of the push plate 408. The push plate 408 pushes the T-shaped plate 401 out of the inner wall of the limit plate 403 and the mounting block 405 a certain distance, which can facilitate the disassembly of the T-shaped plate 401 and the cleaning of the defective product removal shovel 402, thus avoiding the impact of difficult-to-remove stains on the surface of the defective product removal shovel 402 on subsequent work.

[0021] A transmission assembly 2 is provided on one side of the support frame 1, and a stripping plate 5 is provided at the bottom of the support frame 1. The transmission assembly 2 includes a drive chain, which mainly lifts and lowers the mounting plate 3. Then, the defective products on the surface of the stripping plate 5 are scraped off by the defective product removal shovel 402.

[0022] Working principle: First, through the set adjustment mechanism, when removing defective electrolytic zinc cathode plates, the drive chain in the transmission assembly 2 directly drives the mounting plate 3 to move up and down to remove the defective electrolytic zinc cathode plates. When it is necessary to remove the defective products, the mounting plate 3 moves down. At this time, the defective product removal shovel 402 first contacts the stripping plate 5 and scrapes the stripping plate 5. At this time, the support plate 303 will rotate around the connecting shaft 304, and the return spring 302 will be compressed. When scraping the surface of the stripping plate 5, the defective product removal shovel 402 will change along the top of the stripping plate 5. When scraping the defective products, there will be no irreversible wear on the surface, and the scraping effect is good.

[0023] Furthermore, through the disassembly mechanism, after the work is completed, some difficult-to-remove stains may adhere to the surface of the defective product detachment shovel 402, causing trouble for subsequent use. At this time, the defective product detachment shovel 402 can be removed by removing the fixing nut on one side of the baffle 404. At this time, the auxiliary spring 406, which is in a compressed state, will generate a rebound force under its own restoring force. The rebound force acts on one side of the push plate 408, and the push plate 408 pushes the T-shaped plate 401 out of the inner wall of the limiting plate 403 and the mounting block 405 a certain distance, which can facilitate the disassembly of the T-shaped plate 401 and the cleaning of the defective product detachment shovel 402. This avoids the difficulty in removing stains on the surface of the defective product detachment shovel 402 from affecting subsequent work, and the disassembly is simple and the cleaning is relatively easy.
