Description

Technical Field

[0001] This utility model relates to the field of battery separator technology, and in particular to a spray-assisted cooling system for separator processing. Background Technology

[0002] In diaphragm processing, cooling of the casting rollers is a crucial step in ensuring product quality. Current casting processes result in a long suspension distance after extrusion, causing the film to neck towards the center, leading to thicker edges and a wider thickness transition zone. Simultaneously, cooling is ineffective, resulting in uneven temperature distribution. In practice, only one side of the oil film is cooled by the roller, with slow heat dissipation from the air surface. The cooling rate is heavily dependent on the roller temperature, and increasing the cooling speed presents a greater challenge to the cooling water temperature. Furthermore, significant differences exist in the microstructure of the two sides.

[0003] Shortcomings of existing technology: The traditional cooling die head and casting roller have insufficient fit, resulting in uneven distribution of coolant and insufficient heat exchange, which affects the cooling effect.

[0004] The lack of an efficient recycling mechanism means that coolant is directly discharged after use, which not only increases costs but also causes environmental pollution.

[0005] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create a spray-assisted cooling system for diaphragm processing, making it more industrially valuable. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a spray-assisted cooling system for diaphragm processing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A spray-assisted cooling system for diaphragm processing includes a coolant spraying assembly and a casting roller; The coolant spraying assembly includes a coolant spraying die head, which is mounted on a die head base below.

It also includes a coolant recovery and circulation system, which includes an oil receiving tank, a recovery tank, a coolant storage tank, a heat exchanger, and a second filter. An oil receiving tank is provided below the coolant spraying head. The oil receiving tank is connected in sequence to the recovery tank, the coolant storage tank, the heat exchanger, and the second filter, and then to the head cooling cavity.

The first side of the cyclone separator is connected to the recovery tank, and the second side of the cyclone separator is connected to the first filter, the fan and the oil and gas purifier in sequence.

[0010] As a further improvement of this utility model, an iron remover is also connected between the second filter and the oil inlet of the mold head.

[0011] As a further improvement of this utility model, a system detection unit is provided on the connecting pipe between the second filter and the oil inlet of the mold head.

[0015] As a further improvement of this utility model, the mold head base and the oil receiving groove are both integrated and installed on the same working platform.

[0016] By means of the above solution, this utility model has at least the following advantages: The cooling cavity of the mold head of this invention adopts an arc-shaped design, which fits closely with the casting roller to ensure uniform coverage of the coolant and improve heat exchange efficiency.

[0017] This invention utilizes a complete recycling system, allowing coolant to be reused, reducing waste and emissions, and lowering operating costs.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] The first embodiment of this utility model: like Figures 1-2 As shown in the figure, a spray-assisted cooling system for diaphragm processing in this embodiment mainly includes a coolant spraying assembly 1, a casting roller 2, and a coolant recovery and circulation system.

[0028] The coordination between the coolant spraying assembly 1 and the casting roller 2: The core of the coolant spraying assembly 1 is the coolant spraying die head 13, which is mounted on the die head base 16 below. On the side of the coolant spraying die head 13 facing the casting roller 2, there is a die head cooling cavity 14 with an arc-shaped structure. The contact surface inside the cavity is designed to match and closely fit the curvature of the casting roller 2 to ensure that the coolant can form a uniform and stable liquid film, achieving efficient heat exchange.

[0029] Coolant recovery and circulation system: The system is designed to collect, process, and recycle coolant. It consists of a main liquid recovery path and an oil and gas treatment branch path.

[0030] Main path for liquid recovery: Collection: An oil receiving trough 3 is provided below the coolant spraying head 13 to collect coolant flowing down from the roller surface and any that may splash. The oil discharge hole 20 at the bottom of the oil receiving trough 3 is connected to the recovery tank 4 via a pipe.

[0031] Storage and processing: The coolant flows from the recovery tank 4 into the coolant storage tank 9 for temporary storage and initial settling. Subsequently, the coolant is pumped to the heat exchanger 10 for cooling to restore its cooling capacity.

[0032] Fine filtration and supply: The cooled coolant flows through the second filter 11 to remove tiny particulate impurities. To ensure system cleanliness, a magnetic separator 12 is connected in series after the second filter 11 to adsorb and remove any ferromagnetic metal particles that may be present in the coolant. Finally, the clean coolant is reinjected into the mold head cooling chamber 14 through the connecting pipe and the mold head oil inlet 17 at the bottom of the coolant spray mold head 13, completing the circulation.

[0033] Oil and gas processing branch path: Collection: A scraper trough 19 is provided on one side of the top of the coolant spraying die 13 to collect any oil-gas mixture that may escape. The scraper trough is connected to the cyclone separator 5 through the die oil discharge pipe 18.

[0034] Separation and purification: The oil-gas mixture undergoes gas-liquid separation in the cyclone separator 5. The separated liquid portion is discharged from its first side and flows into the recovery tank 4. The gaseous portion passes sequentially from its second side through the first filter 6, the blower 7, and the oil-gas purifier 8, ultimately meeting emission standards.

[0035] Auxiliary and monitoring unit: A system monitoring unit is installed on the connecting pipe between the second filter 11 and the oil inlet 17 of the die head. This unit typically includes, but is not limited to, pressure gauges, thermometers, and flow meters, and is used to monitor the coolant supply status in real time, providing data support for stable system operation and process optimization.

[0036] A coolant replenishment pipeline is installed on the coolant storage tank 9 for automatic or manual replenishment when the coolant is insufficient due to evaporation or loss.

[0037] To optimize the spatial layout and facilitate installation and maintenance, the mold base 16 and the oil receiving groove 3 are both integrated and installed on the same working platform.

[0038] The working process of this embodiment: Cooling and Initial Recovery: Driven by a pump, the clean coolant flows sequentially through the second filter 11 and the iron remover 12, enters the die head cooling chamber 14 through the die head oil inlet 17, and is evenly sprayed onto the surface of the high-speed rotating casting roller 2 for efficient cooling. Most of the used coolant drips directly into the oil receiving tank 3 below under gravity and flows into the recovery tank 4 through the oil discharge hole 20.

[0039] Oil and gas recovery and treatment: The oil and gas mixture generated during the cooling process is captured by the top die oil scraper 19 and introduced into the cyclone separator 5 through the die oil discharge pipe 18. Here, most of the oil is separated and sent back to the recovery tank 4, while the gas is drawn in by the blower 7 and purified by the first filter 6 and the oil and gas purifier 8 before being discharged.

[0040] Recycling: The coolant collected in the recovery tank 4 is sent to the coolant storage tank 9, and then cooled to the set temperature through the heat exchanger 10. The cooled coolant re-enters the second filter 11 and the iron remover 12 for purification, and finally returns to the coolant spray head 13, forming a complete closed loop.

[0041] Monitoring and Maintenance: Operators can monitor the coolant pressure, temperature, and flow rate in real time through the system's detection unit. When the coolant level is low, it can be replenished through the coolant replenishment pipe.

[0042] The second embodiment of this utility model: This embodiment provides a spray-assisted cooling system for diaphragm processing, such as... Figures 1-2As shown, the assembly includes a coolant spraying component 1 and a casting roller 2. The coolant spraying component 1 includes a coolant spraying die 13, which is mounted on a die base 16 via a push-pull cylinder 15 and can move towards or away from the casting roller 2. The coolant spraying die 13 has an arc-shaped die cooling cavity 14 on the side facing the casting roller 2, and its inner contact surface is in close contact with the casting roller 2 to ensure uniform spraying of coolant.

[0043] An oil receiving tank 3 is located below the coolant spraying nozzle 13. An oil discharge hole 20 at the bottom of the oil receiving tank 3 is connected to a recovery tank 4 via a pipe. The recovery tank 4 is sequentially connected to a coolant storage tank 9, a heat exchanger 10, and a second filter 11. The second filter 11 is connected to the nozzle oil inlet 17 via a pipe. A magnetic separator 12 and a system monitoring unit (including a pressure gauge, thermometer, and flow meter) are located between the second filter 11 and the nozzle oil inlet 17. A coolant replenishment pipe is installed on the coolant storage tank 9 for replenishing coolant.

[0044] The coolant spraying die head 13 has an oil scraper 19 at its top connected to a cyclone separator 5 via an oil drain pipe 18. The first side of the cyclone separator 5 is connected to a recovery tank 4, and the second side is sequentially connected to a first filter 6, a blower 7, and an oil and gas purifier 8. The die head base 16 and the oil receiving tank 3 are integrated on the same working platform, forming a compact structure.

[0045] The working process of this embodiment: Cooling stage: Coolant is sprayed from the die head cooling chamber 14 onto the surface of the casting roller 2, absorbs heat and partially evaporates, achieving efficient cooling of the casting roller.

[0046] Recovery stage: The used coolant and splashed liquid droplets fall into the oil receiving tank 3 and flow into the recovery tank 4 through the oil discharge hole 20; at the same time, the oil-gas mixture collected by the die head scraping groove 19 enters the cyclone separator 5 through the die head oil discharge pipe 18.

[0047] Purification stage: In the cyclone separator 5, the oil-gas mixture undergoes gas-liquid separation. The liquid enters the recovery tank 4, and the gas passes through the first filter 6 (to remove particulate matter), the blower 7 (to provide airflow power), and the oil-gas purifier 8 (to adsorb harmful gases) in sequence before being discharged in compliance with standards.

[0048] Circulation stage: The coolant in the recovery tank 4 enters the coolant storage tank 9 for temporary storage. After being cooled by the heat exchanger 10, it passes through the second filter 11 to filter impurities, then passes through the iron remover 12 to remove metal particles, and finally returns to the die head cooling cavity 14 for recycling through the die head oil inlet 17.

[0049] Monitoring and Regulation: The system detection unit monitors the pressure, temperature and flow rate of the coolant in real time and feeds the data back to the control center; the push-pull cylinder 15 automatically adjusts the distance between the coolant spraying head 13 and the casting roller 2 according to process requirements; and the coolant is replenished in a timely manner through the coolant replenishment pipeline to maintain stable system operation.
