Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic copper foil production equipment, specifically to an electrothermal heat-insulating scraper for electrolytic copper foil. Background Technology

[0002] Electrolytic copper foil is widely used as the negative electrode current collector in lithium-ion batteries in energy storage, power, and 3C fields. The production process of electrolytic copper foil is complex. Before peeling off the copper foil obtained by electrodeposition on the cathode roller, the residual copper sulfate solution on its surface needs to be removed. This process usually involves first scraping off the residual liquid on the copper foil with a scraper, and then squeezing the copper foil with a squeezing roller to make the surface of the copper foil completely free of aqueous solution.

[0003] To avoid damaging the cathode roller, the wiper blade must be flexible. Currently, most wiper blades are made of EPDM rubber with a flat front end. However, during the wiping process, the electrolyte is a supersaturated copper sulfate solution (95-100g / L) at 52-56℃. As the temperature drops after the solution reaches the wiper blade, copper sulfate crystals often precipitate. These crystals will form continuous indentations on the copper foil surface during subsequent wiping processes, causing the copper foil to be scrapped.

[0004] Therefore, in order to correct the above-mentioned defects, we propose an electrothermal heat-insulating electrolytic copper foil scraper. Utility Model Content

[0005] The technical problem solved by this utility model is to provide an electrolytic copper foil scraper that can be electrically heated and kept warm.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrolytic copper foil scraper with electrothermal insulation, comprising a flat scraper, wherein an electric heating module is installed on the flat scraper, the heating wire of the electric heating module is located inside the flat scraper, and the flat scraper is made of silicone rubber.

[0007] Furthermore, the upper surface of the flat scraper is equidistantly equipped with several protrusions, the two sides of which are arc-shaped, and the gap between each two adjacent protrusions is a water channel.

[0008] Furthermore, a collecting plate is installed at the end of the flat scraper. The side of the collecting plate facing the flat scraper has a water inlet hole corresponding to the water channel, and a drain valve is installed on the side of the collecting plate away from the flat scraper.

[0009] Furthermore, the side of the collecting plate facing away from the flat scraper has an arc-shaped structure.

[0010] Furthermore, the upper inner part of the collecting plate is the electric heating module installation area, and the lower inner part of the collecting plate is the electric heating wire penetration area and the water collection area. The electric heating wire penetration area is close to the flat scraper, and the electric heating wire penetration area is provided with through holes. The two ends of the through holes are respectively connected to the water collection area and the water inlet hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This device uses a silicone rubber heating plate that can be electrically heated and kept warm. This plate can not only be electrically heated and kept warm at 52-56℃, but also has higher flexibility. At the same time, the traditional flat-end wiper blade is designed with a groove, so that the water scraped off can flow down quickly with the groove and not remain on the wiper blade.

Detailed Implementation

[0013] 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.

[0014] This utility model provides a technical solution: like Figure 1-6 As shown, an electrolytic copper foil scraper with electrothermal insulation includes a flat scraper 1, on which an electrothermal module is installed. The electrothermal module is an existing mature product, which includes a heating wire 9, a power supply module, and a control module. The heating wire 9 of the electrothermal module is located inside the flat scraper 1. The flat scraper 1 is made of silicone rubber. The heating temperature is preset by the control module so that the flat scraper 1 is heated and kept at 52-56℃. In this way, the electrolyte is a supersaturated copper sulfate solution of 95-100g / L at 52-56℃. After it reaches the scraper, it will not cool down, so there will be no crystal precipitation.

[0015] In the above, a number of protrusions 2 are installed at equal intervals on the upper surface of the flat scraper 1. The two sides of the protrusions 2 are arc-shaped. The gap between each pair of adjacent protrusions 2 is a water channel, so that the scraped water can flow down quickly with the water channel and not remain on the scraper. Based on the above, in order to prevent water from flowing freely on the wiper blade during wiping, a collecting plate 3 is installed at the end of the flat wiper blade 1. The side of the collecting plate 3 facing the flat wiper blade 1 has a water inlet hole 4 corresponding to the water channel. The side of the collecting plate 3 away from the flat wiper blade 1 is equipped with a drain valve 5. That is, all the water entering the water channel enters the collecting plate 3 and is then discharged through the drain valve 5 at the end of the collecting plate 3. The drain valve 5 can be connected to a flexible hose to guide the water away.

[0016] Specifically, the upper inner part of the collecting plate 3 is the electric heating module installation area 8, and the lower inner part of the collecting plate 3 is the electric heating wire penetration area 6 and the water collection area 7. The electric heating wire penetration area 6 is close to the flat scraper 1, and the electric heating wire penetration area 6 is provided with a through hole. The two ends of the through hole are connected to the water collection area 7 and the water inlet hole 4, respectively. That is, the power supply module and control module of the electric heating module are installed in the electric heating module installation area 8, and the control panel of the control module is installed on the surface of the collecting plate 3. The water in the water inlet tank enters the through hole, then enters the water collection area 7, and then is discharged from the drain valve 5.

[0017] Among them, the side of the collecting plate 3 facing away from the flat scraper 1 has an arc-shaped structure, which facilitates the rapid flow of water in the water collection area 7 to the drain valve 5.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
