Description

Technical Field

[0001] This utility model belongs to the technical field of battery manufacturing, and in particular relates to a water washing device for pre-forming battery explosion-proof sheets. Background Technology

[0002] Battery explosion-proof discs (also known as explosion-proof valves or rupture discs) are key components for ensuring battery safety, especially in new energy power batteries and energy storage systems. They serve a pressure-relieving and explosion-proof function: when high-pressure gas is generated inside the battery due to thermal runaway, overcharging, or a short circuit, the explosion-proof disc ruptures through a pre-set burst mark (usually V-shaped, angle 40°-120°), instantly releasing pressure and preventing battery explosion. They also provide sealing protection: under normal conditions, they maintain the airtightness of the battery's internal structure, preventing electrolyte leakage or the intrusion of external contaminants. Battery explosion-proof discs are typically made by stamping, but even after pre-forming, they still have the following drawbacks:

[0003] After preforming, battery explosion-proof sheets usually need to be washed with water to remove metal debris, oil, and other contaminants generated during the preforming process, ensuring the cleanliness of the explosion-proof sheets before subsequent assembly. The water washing process includes high-pressure rinsing, ultrasonic cleaning, and rinsing. During high-pressure rinsing, because the battery explosion-proof sheets are small in size, they cannot be cleaned during transportation. They are easily scattered by the water flow, resulting in a messy and disorganized appearance, which can lead to incomplete cleaning. It is impossible to rinse them in a concentrated manner. However, rinsing them one by one would increase the processing cost too much.

[0004] Secondly, during the subsequent ultrasonic cleaning process, some special cleaning agents are required. These cleaning agents may damage the skin of the workers, making it impossible to directly retrieve the battery explosion-proof pads inside the ultrasonic cleaner. Furthermore, if a large number of battery explosion-proof pads settle at the bottom of the ultrasonic cleaner, it will also bring certain difficulties to the retrieval operation. Utility Model Content

[0005] The purpose of this utility model is to provide a water washing device for pre-formed battery explosion-proof sheets. By setting up a water washing tank, conveyor, spray pipe, high-pressure pump, storage component, and ultrasonic cleaner, it solves the problems of not being able to centrally clean during high-pressure cleaning, while individual positioning cleaning is too costly, and the battery explosion-proof sheets settling at the bottom of the ultrasonic cleaner during ultrasonic cleaning, making them difficult to retrieve.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a water washing device for pre-formed battery explosion-proof sheet, including a water washing tank, a high-pressure pump, a conveyor, a spray pipe and a storage component, wherein an ultrasonic cleaner is fixed to one end of the water washing tank.

[0008] An inclined conveyor is fixed to the upper end of the washing tank; the conveyor includes two frames that are inclined and fixed to the end of the washing tank, and rollers that are equidistantly distributed are rotatably connected inside the two frames. A conveyor belt is fitted around all the rollers. The conveyor belt has equally distributed drainage grooves, and a storage component is provided on each drainage groove on the upper part of the conveyor belt.

[0009] The storage assembly includes a cleaning basket located directly above the drain tank, with base blocks fixed at both ends of the cleaning basket, and a float fixed above each base block;

[0010] Two spray pipes are installed above the washing tank, and two sets of inclined and symmetrically distributed nozzles are fixed through the lower part of each spray pipe, with the nozzles inclined downwards towards the center of the conveyor.

[0011] Furthermore, the two ends of the washing tank are at different heights, and the top surface of both ends of the washing tank is provided with grooves. The length of the grooves is equal to the width of the conveyor belt. A filter screen is fixed inside the washing tank. The higher end of the conveyor extends out of the higher end of the washing tank and faces the ultrasonic cleaner. The height of the ultrasonic cleaner is lower than the height of the washing tank.

[0012] Furthermore, a high-pressure pump is fixed to the front side of the washing tank, a water suction pipe is fixed to the water suction end of the high-pressure pump, and the end of the water suction pipe away from the high-pressure pump is fixedly connected to the inner bottom of the washing tank. A water outlet pipe is fixed to the water outlet end of the high-pressure pump, and the end of the water outlet pipe away from the high-pressure pump is fixedly connected to the end of the spray pipe close to it.

[0013] Furthermore, a water inlet pipe is fixedly connected to the front side of the high-pressure pump, and the position of the water inlet pipe is lower than the height of the filter screen.

[0014] Furthermore, a connecting rod is provided between each of the two adjacent rollers, and the two ends of the connecting rod are fixedly connected to the opposite surfaces of the two frames. The side length of the connecting rod is smaller than the diameter of the roller.

[0015] Furthermore, the washing basket and the drain trough have the same cross-section, and a through groove is also opened on one side of the conveyor belt of each drain trough. Symmetrically distributed pads are fixed on the outer surface of the conveyor belt between adjacent drain troughs and through grooves.

[0016] Furthermore, the opening of the cleaning basket is angled upwards, a rod is fixed to the lower side of the base block and inserted into a nearby pad, a limit rod is fixed to the higher side of the base block, a limit block is fixed to the outer periphery of the limit rod, a sealing plate is fitted around the two limit rods, a handle is fixed to the center of the sealing plate away from the cleaning basket, the sealing plate is located between the limit block and the cleaning basket, a spring is fixed between the sealing plate and the opposite face of the limit block outside the limit rod, and the cover is placed outside the opening side of the cleaning basket.

[0017] Furthermore, a support rod is fixed below both ends of the spray pipe, and the bottom end of the support rod is fixed above the side of the washing tank. A connecting pipe is fixed through the two support rods.

[0018] This utility model has the following beneficial effects:

[0019] This invention solves the problems of centralized cleaning during high-pressure cleaning and the excessive cost of individual cleaning by setting up a washing tank, conveyor, spray pipe, high-pressure pump, and storage component. Before high-pressure cleaning, a small number of battery explosion-proof sheets to be cleaned are placed in the storage component. Then, these storage components containing battery explosion-proof sheets are placed on a conveyor belt and moved with the operation of the conveyor. As the conveyor belt operates, it drives the storage component and the battery explosion-proof sheets inside to move until they enter the area below the spray pipe. The high-pressure pump draws water from the washing tank and outputs it from the outlet pipe to the spray pipe, and then sprays it out from the nozzle to rinse the battery explosion-proof sheets in the storage component below. Because of the cleaning basket in the storage component, the battery explosion-proof sheets cannot be washed away by the water flow, but can only tumble in the cleaning basket, thereby washing away impurities on the surface of the battery explosion-proof sheets. This achieves centralized cleaning of small quantities and eliminates the need for individual cleaning of each explosion-proof sheet, saving operating costs.

[0020] This invention solves the problem of battery explosion-proof sheets settling at the bottom of the ultrasonic cleaner and being difficult to retrieve during ultrasonic cleaning by incorporating an ultrasonic cleaner and a storage component. After high-pressure spray rinsing on a conveyor belt, the storage component flips as it reaches its highest point, naturally falling into the ultrasonic cleaner. Due to the float within the storage component, the cleaning basket and the battery explosion-proof sheets inside naturally float along with it. In this state, the cleaning basket and the battery explosion-proof sheets are located in the water within the ultrasonic cleaner, while the float remains on the surface. This allows for thorough ultrasonic cleaning and facilitates easy removal after cleaning, eliminating the need for manual retrieval from the bottom of the ultrasonic cleaner, making the operation simpler and more convenient.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0035] Please see Figure 1-10As shown, this utility model is a water washing device for pre-formed battery explosion-proof sheet, including a water washing tank 1, a high-pressure pump 2, a conveyor 3, a spray pipe 4 and a storage component 6. An ultrasonic cleaner 5 is fixed to one end of the water washing tank 1.

[0036] The battery explosion-proof sheet is cleaned by high-pressure spray in the water washing tank 1, and then enters the ultrasonic cleaner 5 for ultrasonic cleaning.

[0037] An inclined conveyor 3 is fixed to the upper end of the washing tank 1; the conveyor 3 includes two inclined frames 301 fixed to the ends of the washing tank 1, and equidistant rollers 302 are rotatably connected inside the two frames 301. A conveyor belt 303 is sleeved on all rollers 302. Equidistant drainage grooves 3033 are opened on the conveyor belt 303. A storage component 6 is provided on each drainage groove 3033 on the upper part of the conveyor belt 303.

[0038] The conveyor 3 is installed at an angle to facilitate the timely discharge of cleaning water after cleaning. When the conveyor 3 is working, the conveyor belt 303 runs from low to high. The conveyor belt 303 is synchronously sleeved on the outside of the drum 302 for transporting the storage component 6. The rotating drum 302 is installed inside the two frames 301 to assist the drive of the conveyor belt 303.

[0039] The storage component 6 includes a cleaning basket 601 located directly above the drain trough 3033, and base blocks 602 are fixed at both ends of the cleaning basket 601, with a float block 604 fixed above each base block 602.

[0040] The cleaning basket 601 stores a small number of battery explosion-proof sheets, and a base block 602 is installed at its end. A float block 604 is installed on the base block 602. The function of the float block 604 is to make the cleaning basket 601 float on the water.

[0041] Two spray pipes 4 are installed above the water washing tank 1, and two sets of inclined and symmetrically distributed nozzles 402 are fixed through the lower part of each spray pipe 4. The nozzles 402 are inclined downward towards the center of the conveyor 3.

[0042] As the main spraying component, the spray pipe 4 sprays the cleaning water inside through the nozzle 402. The inclined nozzle 402 concentrates the water towards the storage component 6 running on the conveyor 3 for rinsing.

[0043] The two ends of the washing tank 1 are at different heights, and the top surface of both ends of the washing tank 1 is provided with a groove 102. The length of the groove 102 is equal to the width of the conveyor belt 303. A filter screen 103 is fixed inside the washing tank 1. The higher end of the conveyor 3 extends out of the higher end of the washing tank 1 and faces the ultrasonic cleaner 5. The height of the ultrasonic cleaner 5 is lower than the height of the washing tank 1.

[0044] The two ends of the washing tank 1 are at different heights, so the conveyor 3 is installed at an angle. The groove 102 is designed to allow the pads 3031 on the surface of the conveyor belt 303 to pass through normally when it is running. A filter screen 103 is installed inside the washing tank 1. The wastewater generated during cleaning is filtered through the filter screen 103 and enters the bottom of the washing tank 1. After impurities are filtered out, the wastewater can be recycled. When the conveyor 3 carrying the storage component 6 runs to the top, the conveyor 3 flips over. At this time, the storage component 6 falls naturally into the ultrasonic cleaner 5 for ultrasonic cleaning. The drive motor in the conveyor 3 is omitted in the attached drawing.

[0045] A high-pressure pump 2 is fixed to the front side of the washing tank 1. A water suction pipe 201 is fixed to the water suction end of the high-pressure pump 2, and the end of the water suction pipe 201 away from the high-pressure pump 2 is fixed to the inner bottom of the washing tank 1. A water outlet pipe 202 is fixed to the water outlet end of the high-pressure pump 2, and the end of the water outlet pipe 202 away from the high-pressure pump 2 is fixedly connected to the end of the spray pipe 4 that is close to it.

[0046] The high-pressure pump 2 draws the cleaning water from the washing tank 1, extracts it through the water extraction pipe 201, and then discharges it from the water outlet pipe 202, which is then fed into the spray pipe 4.

[0047] A water inlet pipe 101 is also fixed through the front side of the high-pressure pump 2, and the position of the water inlet pipe 101 is lower than the height of the filter screen 103; the water inlet pipe 101 is used to add cleaning water, and the water level is not higher than the height of the filter screen 103.

[0048] A connecting rod 304 is provided between each of the two adjacent rollers 302, and the two ends of the connecting rod 304 are fixedly connected to the opposite surfaces of the two frames 301. The side length of the connecting rod 304 is smaller than the diameter of the roller 302.

[0049] Connecting rods 304 are installed between the frames 301 to strengthen the overall structural strength of the conveyor 3.

[0050] The cross-sections of the cleaning basket 601 and the drain trough 3033 are equal. A through groove 3032 is also provided on the conveyor belt 303 on one side of each drain trough 3033. A symmetrically distributed pad block 3031 is fixed on the outer surface of the conveyor belt 303 between adjacent drain troughs 3033 and through grooves 3032.

[0051] The cleaning basket 601 is placed above the drain trough 3033. The wastewater generated during cleaning will leak down through the drain trough 3033, and the excess wastewater will slide down the inclined surface of the conveyor belt 303 and slide down into the through trough 3032.

[0052] The opening of the cleaning basket 601 is angled upward. A rod 6021 is fixed to the lower side of the base block 602, and the rod 6021 is inserted into the pad 3031 that is close to it. A limit rod 6022 is fixed to the higher side of the base block 602. A limit block 6023 is fixed to the outer periphery of the limit rod 6022. A sealing plate 603 is sleeved on both limit rods 6022. A handle 6031 is fixed to the center of the sealing plate 603 away from the center of the cleaning basket 601. The sealing plate 603 is located between the limit block 6023 and the cleaning basket 601. A spring 6024 is fixed between the opposite surfaces of the sealing plate 603 and the limit block 6023 outside the limit rod 6022. The cover is placed on the outside of the opening side of the cleaning basket 601.

[0053] When installing the storage component 6, the sealing plate 603 is pulled open by the handle 6031. The spring 6024 deforms in the shape of the limit block 6023. First, the battery explosion-proof sheet is placed in the cleaning basket 601. The spring 6024 returns to its original shape. Then, the sealing plate 603 closes the cleaning basket 601. Then, the insertion rod 6021 is inserted into the pad 3031. At this time, the cleaning basket 601 is located above the drain trough 3033. As the cleaning proceeds, the wastewater will leak out from the drain trough 3033.

[0054] Both ends of the spray pipe 4 are fixed with support rods 401. The bottom of the support rods 401 is fixed to the upper side of the washing tank 1. A connecting pipe 403 is fixed between the two support rods 401. The spray pipe 4 is installed above the washing tank 1 through the support rods 401. The two spray pipes 4 are connected through the connecting pipe 403 so that the two spray pipes 4 can spray and clean at the same time.

[0055] The specific working principle of this utility model is as follows: First, a small amount of battery explosion-proof pads are placed in the storage component 6. The sealing plate 603 is opened by pulling the handle 6031, and the spring 6024 deforms at the limit block 6023, opening the opening side of the cleaning basket 601. The battery explosion-proof pads are placed in the cleaning basket 601. After releasing the handle 6031, the spring 6024 returns to its original deformation, and then the sealing plate 603 closes the cleaning basket 601. Then, the insertion rod 6021 is inserted into the pad 3031. At this time, the cleaning basket 601 is located above the drain trough 3033. After the conveyor 3 starts running, the storage component 6 moves with the conveyor belt 303. Then the conveyor 3 works, and the external motor drives the roller 302 to rotate, and the conveyor belt 303 moves accordingly, carrying the storage component 6 towards the ultrasonic cleaner 5 until it enters below the spray pipe 4. The high-pressure pump 2 draws the cleaning water from the washing tank 1 and pumps it out through the water suction pipe 201. The water flows out through the outlet pipe 202 and into the spray pipe 4, then sprays out from the nozzle 402 to rinse the battery explosion-proof sheet in the storage component 6 below. Because of the cleaning basket 601 in the storage component 6, the battery explosion-proof sheet cannot be washed away by the water flow, but can only tumble in the cleaning basket 601, thereby rinsing away impurities on the surface of the battery explosion-proof sheet. As the conveyor belt 303 runs, when the storage component 6 runs to the highest point with the conveyor belt 303, it flips over. At this time, the storage component 6 naturally falls into the ultrasonic cleaner 5. Because of the float 604 in the storage component 6, it will naturally float along with the cleaning basket 601 and the battery explosion-proof sheet inside. In this state, the cleaning basket 601 and the battery explosion-proof sheet inside are located in the water in the ultrasonic cleaner 5, and the float 604 floats on the water surface. This allows for thorough ultrasonic cleaning and makes it easy to remove the battery after cleaning.

[0056] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
