Description

Technical Field

[0001] This utility model belongs to the field of diaphragm cleaning technology, and in particular relates to a spray diaphragm cleaning machine. Background Technology

[0002] AGM separators, also known as battery separators, are a core material in valve-regulated sealed lead-acid batteries (VRLA batteries). They are made from ultra-fine glass fibers with a diameter of 0.4-3 μm using a wet process. They possess excellent properties, such as good acid resistance, uniform thickness, high porosity, rapid electrolyte absorption, and good tensile strength and elongation in both the longitudinal and transverse directions. In the battery, AGM separators play a crucial role in fixing the electrolyte, providing hydrogen-oxygen recombination channels during charging and discharging, preventing the shedding of active materials from the electrodes, slowing down lead dendrite formation, and reducing electrolyte loss during charging and discharging. This ultimately enables lead-acid batteries to achieve maintenance-free operation and extend their service life.

[0003] In battery production, to ensure the performance of AGM membranes, they require spray cleaning to remove surface impurities. Existing traditional spray cleaning machines typically use conveyor rollers to transport the AGM membranes while simultaneously using upper spray pipes for cleaning. However, because the sprayed liquid is high-pressure, it causes deformation of the membrane surface due to the impact force. If this deformation is not effectively controlled and utilized, it can lead to excessive membrane deformation, affecting its structure and performance. Furthermore, relying solely on the upper spray pipes results in limited cleaning effectiveness, failing to thoroughly remove impurities from the complex microporous structure of the membrane or its back surface, thus failing to meet increasingly stringent production quality standards.

[0004] Therefore, it is essential to invent a spray diaphragm cleaning machine. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a spray diaphragm cleaning machine, including a water storage tank, a filter screen, a spray hood, conveying rollers, an upper support plate, a lower support plate, a pressure sensor, an upper spray pipe, a lower spray pipe, an integrated pipe, a connecting pipe, a water pump, and a diaphragm. A filter screen is fixedly installed on the upper part of the water storage tank. The spray hood is fixedly installed on the upper part of the water storage tank. Several horizontally equidistant conveying rollers are rotatably installed inside the spray hood, and the diaphragm is conveyed on the conveying rollers. The upper and lower support plates are fixedly installed inside the water storage tank, and the pressure sensor is installed on the surface of both plates. The inner wall of the water storage tank is fixedly connected to one end of several upper and lower spray pipes, and the other ends of the upper and lower spray pipes protrude outside and are fixedly connected to the integrated pipe. The integrated pipe is connected to the water storage tank through the connecting pipe and the water pump. Two water pumps are fixedly installed outside the water storage tank.

[0006] Preferably, a number of upper and lower support plates are fixedly installed inside the water storage tank in a staggered manner, and waterproof pressure sensors are embedded on the surface of both plates facing the diaphragm.

[0007] Preferably, the upper support plate is located above the diaphragm, the lower support plate is located below the diaphragm, and the upper and lower support plates are spaced less than two centimeters apart from the diaphragm.

[0008] Preferably, the upper support plate, the lower support plate, the upper spray pipe, and the lower spray pipe are all located between the two conveying rollers. The upper spray pipe is located above the diaphragm and is correspondingly arranged with the lower support plate. The lower spray pipe is located below the diaphragm and is correspondingly arranged with the upper support plate.

[0009] Preferably, the upper and lower spray pipes are each equidistantly arranged with several high-pressure nozzles facing the diaphragm surface. The upper spray pipe and the lower support plate form a cleaning area for the upper surface of the diaphragm, and the upper support plate and the lower spray pipe form a cleaning area for the lower surface of the diaphragm. The liquid sprayed by the upper and lower spray pipes can flow back and fall into the water storage tank below.

[0010] Preferably, the same ends of several of the upper spray pipes and the lower support plate extend out of the water storage tank and are connected to the corresponding integrated pipe fixedly installed outside the water storage tank. The water pump can inject the liquid inside the water storage tank into the integrated pipe through the connecting pipe, and then inject the liquid into the upper spray pipe and the lower spray pipe through the integrated pipe.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes upper and lower support plates spaced at a specific interval above and below a diaphragm. When high-pressure liquid is sprayed from the upper and lower spray pipes and acts on the diaphragm, causing it to deform, the diaphragm precisely contacts the upper and lower support plates. At this time, the support plates support the diaphragm and limit excessive deformation. Simultaneously, the impact force of the high-pressure spray enhances the scouring effect on impurities on the diaphragm surface, achieving more efficient and thorough cleaning of the diaphragm while ensuring cleaning quality and minimizing damage to the diaphragm structure.

[0012] This invention features upper and lower spray pipes that, together with their corresponding support plates, form cleaning zones on the upper and lower surfaces of the diaphragm. During diaphragm transport, the upper and lower spray pipes operate simultaneously, providing double-sided spray cleaning of the diaphragm. Furthermore, due to the dynamic contact between the diaphragm and the support plate under high-pressure spraying, a unique composite cleaning mode is formed. Compared to the traditional method of spraying only from above, this significantly improves cleaning efficiency, allowing the diaphragm cleaning task to be completed in a shorter time and increasing production efficiency.

[0013] The components of this utility model are arranged in a compact and reasonable manner. Inside the water storage tank, the upper and lower support plates are fixedly installed in a staggered manner. The upper and lower spray pipes, the upper and lower support plates are all located between the two conveyor rollers, making full use of the internal space of the equipment. This design not only ensures the realization of the cleaning function, but also makes the overall structure of the equipment more stable, and facilitates installation, maintenance and layout on the production line.

Those skilled in the art can understand the specific meaning of the above terms in the present utility model based on the specific circumstances.

[0021] As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a spray diaphragm cleaning machine, comprising a water storage tank 1, a filter screen 2, a spray hood 3, conveyor rollers 4, an upper support plate 5, a lower support plate 6, a pressure sensor 7, an upper spray pipe 8, a lower spray pipe 9, an integrated pipe 10, a connecting pipe 11, a water pump 12, and a diaphragm 13. The filter screen 2 is fixedly installed above the interior of the water storage tank 1. The spray hood 3 is fixedly installed above the water storage tank 1. Several horizontally equidistant conveyor rollers 4 are rotatably installed inside the spray hood 3, and the conveyor rollers 4 convey water... The diaphragm 13; the upper support plate 5 and the lower support plate 6 are fixedly installed inside the water storage tank 1, and the pressure sensor 7 is installed on the surface of both; the inner wall of the water storage tank 1 is fixedly connected to one end of several upper spray pipes 8 and lower spray pipes 9, and the other end of the upper spray pipes 8 and lower spray pipes 9 protrudes out and is fixedly connected to the integrated pipe 10. The integrated pipe 10 is connected to the water storage tank 1 through the connecting pipe 11 and the water pump 12. Two water pumps 12 are fixedly installed outside the water storage tank 1.

[0022] Furthermore, to achieve alternating support and cleaning coordination on both sides of the diaphragm 13, several upper support plates 5 and lower support plates 6 are fixedly installed inside the water storage tank 1 in a staggered arrangement. Specifically, adjacent upper support plates 5 and lower support plates 6 are staggered in the horizontal position, meaning that the projection area of ​​one upper support plate 5 corresponds to the gap between two adjacent lower support plates 6 below, avoiding vertical overlap and interference with the conveying of the diaphragm 13. Both upper support plates 5 and lower support plates 6 are made of 304 stainless steel, and their surfaces are polished to reduce frictional damage to the diaphragm 13. Mounting grooves are provided on the surfaces of both facing the diaphragm 13, and waterproof pressure sensors 7 are embedded in these grooves. The pressure sensors 7 are piezoelectric sensors with an IP68 protection rating, and their sensing surfaces are flush with the surface of the support plates. They are fixed and sealed to the inner wall of the mounting groove with food-grade sealant, ensuring accurate detection of the deformation contact pressure of the diaphragm 13 while preventing cleaning fluid from seeping in and affecting sensor performance.

[0023] Furthermore, from a spatial perspective, the upper support plate 5 is horizontally suspended directly above the diaphragm 13, and the lower support plate 6 is horizontally supported directly below the diaphragm 13. Both plates maintain a distance of less than two centimeters from the diaphragm 13 (this distance can be adjusted by adding adjustable stainless steel shims at the connection between the support plate and the inner wall of the water storage tank 1; the standard adjustment range is 0.5-1.8 centimeters). This spacing is designed to ensure that when the diaphragm 13 deforms under spray pressure, it can quickly contact the corresponding support plate surface within a deformation range of 1-2 millimeters. This avoids excessive deformation and damage to the diaphragm 13 due to excessive spacing, while also preventing insufficient spacing from affecting the normal transport of the diaphragm 13. Simultaneously, the lengths of both the upper and lower support plates 5 and 6 are adapted to the width of the diaphragm 13, ensuring adequate lateral coverage of the diaphragm 13.

[0024] Furthermore, to improve the space utilization between the two conveyor rollers 4, the upper support plate 5, lower support plate 6, upper spray pipe 8, and lower spray pipe 9 are all centrally arranged within the cleaning section between the two conveyor rollers 4. The upper spray pipe 8 is positioned parallel above the diaphragm 13, and its axis coincides with the axis of the lower support plate 6 in the vertical projection—meaning the high-pressure water jet from the upper spray pipe 8 can act perpendicularly on the area on the upper surface of the diaphragm 13 corresponding to the lower support plate 6, allowing the diaphragm 13 to precisely adhere to the lower support plate 6 when deforming downwards. The lower spray pipe 9 is positioned parallel below the diaphragm 13, and its axis coincides with the axis of the upper support plate 5 in the vertical projection, similarly allowing the diaphragm 13 to adhere to the upper support plate 5 when deforming upwards.

[0025] Furthermore, several high-pressure nozzles (8-10 cm apart) are equidistantly arranged along the axial direction on the side of the upper spray pipe 8 and the lower spray pipe 9 facing the surface of the diaphragm 13. The nozzles are made of stainless steel and can spray the cleaning fluid onto the diaphragm 13 at a pressure of 0.3-0.8 MPa. The nozzles of the upper spray pipe 8 and the lower support plate 6 form a cleaning area for the upper surface of the diaphragm 13: when the high-pressure water flow impacts the upper surface of the diaphragm 13, the diaphragm 13 bends and deforms downward and sticks tightly to the lower support plate 6. The impact force of the water flow and the supporting force of the lower support plate 6 work together to efficiently remove impurities attached to the upper surface. Similarly, the upper support plate 5 and the lower spray pipe 9 form a cleaning area for the lower surface of the diaphragm 13. In addition, the inner wall of the spray hood 2 has an inclined flow guiding structure. After the liquid sprayed by the upper spray pipe 8 and the lower spray pipe 9 is guided by the surface of the diaphragm 13 and collected on the inner wall of the spray hood 2, it can flow back and fall into the water storage tank 1 below, realizing the initial recovery of the cleaning liquid.

[0026] Furthermore, to achieve centralized supply of cleaning fluid, the same end of several upper spray pipes 8 protrudes through a pre-set sealing hole on the side wall of the water storage tank 1 (a rubber sealing ring is installed in the hole to prevent leakage), and is welded to the upper integrated pipe 10 fixedly installed on the outside of the water storage tank 1; similarly, the same end of several lower spray pipes 9 protrudes from the water storage tank 1 and is connected to the lower integrated pipe 10 on the other side of the outside. The integrated pipe 10 is made of seamless steel pipe, one end of which is connected to one end of the connecting pipe 11 through a flange, and the other end of the connecting pipe 11 is connected to the outlet of the water pump 12 through a quick connector. The inlet of the water pump 12 extends through a pipe to below the filter screen 1 inside the water storage tank 1. When the water pump 12 starts, the cleaning fluid filtered by the filter screen 1 in the water storage tank 1 can be pressurized and injected into the integrated pipe 10 through the connecting pipe 11, and then evenly distributed by the integrated pipe 10 to each upper spray pipe 8 and lower spray pipe 9, forming a closed-loop cleaning fluid circulation path.

[0027] The working principle is as follows: First, before starting the equipment, sufficient cleaning solution needs to be injected into the water storage tank 1 (deionized water or special cleaning solvent can be selected according to the characteristics of the stains on the diaphragm 13). The cleaning solution is initially filtered by the filter screen 2 at the top inside the water storage tank 1 to remove large particles of impurities and ensure the cleanliness of the initial cleaning solution. At the same time, check the sealing status between the spray cover 3 and the water storage tank 1 to ensure that the liquid does not overflow during the cleaning process.

[0028] Then, the diaphragm 13 to be cleaned is smoothly conveyed inside the sprayer hood 3 by a number of transversely equidistant conveying rollers 4 through the winding and unwinding mechanisms set at both ends of the outside. Its surface is covered with a wear-resistant rubber layer to avoid scratching the surface of the diaphragm 13. The diaphragm 13 is kept taut during the conveying process and passes through each cleaning section in sequence.

[0029] Next, the two water pumps 12 outside the water storage tank 1 are started. The water pumps 12 draw the filtered cleaning liquid from below the filter screen 2 inside the water storage tank 1 through the water inlet pipe. After being pressurized, the liquid is transported to the integrated pipe 10 through the connecting pipe 11. The integrated pipe 10 evenly distributes the cleaning liquid to the upper spray pipe 8 and the lower spray pipe 9 connected to it. Finally, the liquid is sprayed out from the upper spray pipe 8 and the lower spray pipe 9 toward the high-pressure nozzle of the diaphragm 13. The spray pressure is controlled at 0.3-0.8MPa.

[0030] Simultaneously, when the high-pressure water flow from the upper spray pipe 8 impacts the upper surface of the diaphragm 13, the diaphragm 13 deforms downwards under the impact force. Because the distance between the upper support plate 5 and the diaphragm 13 is less than 2 cm, the diaphragm 13 quickly adheres to the lower support plate 6 below. The lower support plate 6 provides support force, which, together with the impact force of the water flow, forms an efficient cleaning of the upper surface of the diaphragm 13. Impurities attached to the upper surface are washed away under the dual action. Similarly, when the high-pressure water flow from the lower spray pipe 9 impacts the lower surface of the diaphragm 13, the diaphragm 13 deforms upwards and adheres to the upper support plate 5 above, achieving cleaning of the lower surface. Furthermore, because the upper support plate 5 and the lower support plate 6 are arranged in a staggered manner, the diaphragm 13 alternately contacts both during transportation, completing double-sided cleaning without dead angles.

[0031] During this process, the waterproof pressure sensors 7 on the surfaces of the upper support plate 5 and the lower support plate 6 detect the contact pressure of the diaphragm 13 in real time. If the pressure exceeds the preset threshold (such as excessive deformation due to excessive water pressure), a signal can be fed back to the control system (not shown in the figure). The spray pressure is reduced by adjusting the speed of the water pump 12 to avoid damage to the diaphragm 13. If the pressure is too low, the water pressure is increased to ensure the cleaning effect.

[0032] Finally, the cleaning fluid after spraying is guided through the surface of the diaphragm 13 to the inner wall of the sprayer hood 3. Because the inner wall of the sprayer hood 3 is an inclined guiding structure, the liquid gathers along the inner wall and flows back into the water storage tank 1. It is then filtered again by the filter screen 2 to remove the impurities washed down, thus realizing the closed-loop recycling of the cleaning fluid.

[0033] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
