Technical Field
[0001] This utility model relates to the field of cleaning devices, and in particular to a cleaning device for lithium battery PMMA binder raw materials. Background Technology
[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as positive and negative electrode materials and a non-aqueous electrolyte solution. PMMA (polymethyl methacrylate) binder in lithium-ion batteries is an important component of the battery electrode materials. It is mainly used to fix the positive and negative electrode materials of the battery to improve the mechanical strength and vibration resistance of the battery. In order to remove impurities, improve adhesion performance, ensure product quality, and meet production needs, the raw materials of lithium-ion battery PMMA binder usually need to be cleaned. The lithium-ion battery PMMA binder raw material cleaning equipment is mainly used to clean impurities, oil stains, mold release agents, plasticizers, plasticizers and other contaminants that may adhere to the PMMA binder raw materials during production and storage.
[0003] Existing lithium battery PMMA binder raw material cleaning devices typically involve directly immersing the raw material in a water tank for stirring and cleaning, followed by sieving. This makes it difficult to effectively separate impurity particles with similar particle sizes to the raw material, resulting in a decrease in cleaning efficiency.
[0004] Therefore, the existing lithium battery PMMA binder raw material cleaning devices typically directly put the raw material into a water tank for stirring and cleaning, followed by sieving. However, it is difficult to effectively separate impurity particles with similar particle size to the raw material, resulting in a decrease in cleaning effect. By filtering larger impurity particles in the raw material before cleaning, and then adding a dissolving agent to dissolve the pre-filtered binder and combining it with water washing and filtration, the binder and impurity particles can be completely separated, resulting in a better cleaning effect.

[0014] The beneficial effects of this utility model are:
[0015] 1. By filtering larger particles of impurities in the raw materials before cleaning, and then adding a dissolving agent to dissolve the pre-filtered binder and combining it with water washing and filtration, the binder and impurity particles can be completely separated, resulting in a better cleaning effect. By setting up a filter box with a filter plate, impurities can be pre-filtered to remove larger particles, thus reducing the burden of subsequent cleaning. By setting up a cleaning module on the cleaning box, dissolving agents and water can be added to the cleaning box to dissolve the impurities first, and then water washing can be used to rinse and filter the impurities. The dissolved binder enters the drying box through the filter screen, which can completely separate the binder from the impurities, thus resulting in a better cleaning effect.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Please see Figures 3-4In this embodiment, vibration motors 7 for accelerating filtration are fixedly installed at the left and right ends of the filter box 1, which are arranged opposite to each other. A filter plate 6 for filtering impurity particles is fixedly installed at the bottom of the filter box 1.

A control valve for controlling the inflow and outflow is provided on the outside of the feed hopper 5. A first door 8 for opening and closing is provided at the front end of the filter box 1. By providing the first door 8, it is convenient to clean the filtered impurities. The washing box 2 and the drying box 3 are connected by a guide hopper 9. A filter screen for filtering impurities is fixedly installed at the connection between the guide hopper 9 and the washing box 2. A control valve for controlling the inflow and outflow is provided on the outside of the guide hopper 9. A second door 10 for opening and closing is provided at the front end of the washing box 2. By providing the second door 10, it is convenient to clean the impurities left by the washing and filtration.
[0029] Please see Figure 5 In this embodiment, the cleaning module includes a water tank 401, a water inlet pipe 402, a spray pipe 403, a connecting pipe 405, a water pressure controller 406, and a solvent hopper 407. The spray pipe 403 is fixedly installed on the inner top of the cleaning tank 2. The water tank 401 and the spray pipe 403 are connected through the connecting pipe 405. The inner side of the spray pipe 403 is evenly distributed with spray holes 404 for spraying water. A solvent hopper 407 for introducing relevant solvents is fixedly installed on the upper left side of the cleaning tank 2. The lower end of the solvent hopper 407 extends through the upper end of the cleaning tank 2 and connects to the spray pipe 403. A water inlet pipe 402 for introducing water is fixedly installed at the upper rear of the water tank 401. Both the water inlet pipe 402 and the outside of the solvent hopper 407 are equipped with control valves for controlling the inlet and outlet. A water pressure controller 406 for controlling the water pressure is fixedly installed at the upper middle of the water tank 401. By setting the water pressure controller 406, it is convenient to adjust the water pressure at the spray nozzle 404 according to the reagent cleaning requirements.
[0030] Please see Figures 6-7 In this embodiment, a heating coil 12 for heating is embedded in the bottom of the drying chamber 3. One end of the heating coil 12 extends through the interior of the drying chamber 3 to the outside and is fixedly connected to a control module 13 for controlling the temperature and working state of the heating coil 12. By setting the control module 13, it is convenient to adjust the temperature of the heating coil 12 according to the drying of the reagent. Heat dissipation grooves 11 for heat dissipation are evenly distributed on the upper part of both the left and right ends of the drying chamber 3. A third door 14 for opening and closing is provided at the front end of the drying chamber 3. A base 15 for increasing stability is fixedly connected to the lower end of the drying chamber 3. Mounting holes 16 for mounting and fixing the base 15 are opened around the four corners of the upper end of the base 15. By setting a base 15 with mounting holes 16 at the lower end of the drying chamber 3, a stable support can be formed for the upper structure, thereby increasing the stability of the device during operation.
[0031] When working, first place the device in the corresponding position, install and fix the base 15 through the mounting hole 16 on the base 15, and introduce water into the water tank 401 for storage through the water inlet pipe 402, and close the control valve on the outside of the water inlet pipe 402.
[0032] Then open the control valve on the outside of the feed hopper 5 to introduce the binder raw material into the filter box 1, and then close the control valve on the outside of the feed hopper 5.
[0033] The vibrating motor 7 vibrates, causing the adhesive to separate from the larger particles of impurities. The filtered adhesive then enters the cleaning tank 2 through the filter plate 6.
[0034] Then, the water pressure is adjusted to a suitable level by the water pressure controller 406, so that the spray hole 404 at the spray pipe 403 sprays an appropriate amount of water into the cleaning tank 2, and an appropriate amount of dissolving reagent is introduced into the cleaning tank 2 through the solvent hopper 407 to dissolve the adhesive.
[0035] Then, the water pressure is adjusted to a suitable level by the water pressure controller 406 to rinse the impurities and dissolved adhesive in the cleaning tank 2, so that the impurity particles are blocked by the filter screen in the cleaning tank 2, and the dissolved adhesive enters the drying box 3 below.
[0036] Then, the heating tube is adjusted to a suitable temperature by the control module 13 to heat the inside of the drying oven 3. The water vapor generated during the heating process is dissipated through the heat dissipation groove 11.
[0037] After drying, impurity particles are removed through the first door 8 and the second door 10, and the dried adhesive is exported to the corresponding location for storage through the third door 14.
[0038] Through the above steps, by filtering larger particles of impurities in the raw material before cleaning, and then adding a dissolving agent to dissolve the pre-filtered binder and combining it with water washing and filtration, the binder and impurity particles can be completely separated, resulting in a better cleaning effect. By setting up a filter box 1 with filter plates 6, impurities can be pre-filtered to remove larger particles, thus reducing the burden of subsequent cleaning. By setting up a cleaning module on the cleaning box 2, dissolving agents and water can be added to the cleaning box 2 to dissolve the impurities first, and then water washing can be used to rinse and filter the impurities. The dissolved binder enters the drying box 3 through the filter screen, which can completely separate the binder from the impurities, thus improving the cleaning effect. This solves the problem that existing lithium battery PMMA binder raw material cleaning devices usually directly put the raw material into a water tank for stirring and cleaning, and then perform sieving. It is difficult to effectively separate impurity particles with similar particle size to the raw material, resulting in a decrease in cleaning effect.
