Description

Technical Field

[0001] This utility model belongs to the technical field of storage battery production equipment, and in particular relates to a cooling water tank for storage batteries. Background Technology

[0002] During the production of lead-acid batteries, an acid-adding process is performed. After acid addition, the lead-acid battery generates a large amount of heat due to exothermic chemical reactions and sulfuric acid dilution processes. At this time, cooling is required to ensure that the battery is within a safe temperature range. This is to prevent problems such as deformation, swelling, softening and shedding of active materials, excessive water evaporation, and electrolyte concentration imbalance caused by excessive temperature, which would also reduce the quality and performance of the battery.

[0003] Chinese patent CN202996985U, entitled "A Cooling Water Tank for Internally Formed Lead-Acid Batteries After Acid Addition," discloses a cooling water tank for internally formed lead-acid batteries after acid addition, in which a power chain is installed. After acid addition, the internally formed lead-acid battery is promptly placed on the chain and transported to the charging rack by flowing water. At this time, the tank is filled with cooling water, completely avoiding the problem of excessive battery temperature rise after acid addition.

[0004] Chinese patent CN218448381U, entitled "A Cooling Water Tank for Lead-Acid Batteries," discloses a cooling water tank for lead-acid batteries. The tank includes a second water tank with multiple first water tanks fixed perpendicularly to its right side. The first and second water tanks are connected. The end of each first water tank furthest from the second water tank corresponds to the outlet of an acid-adding machine. A lowering mechanism is located at the end of each first water tank furthest from the second water tank. This patent, by establishing a connected first and second water tank, increases the contact time between the lead-acid battery and the cooling water after acid addition, thereby improving the cooling effect on the battery.

[0005] Currently, batteries undergoing acid addition and after acid addition are placed on a conveyor chain in a cooling water tank to achieve overall cooling, combining automated conveying with efficient heat dissipation. However, due to the relatively low flow resistance of the cooling water on both sides of the batteries in the cooling water tank and the insufficient gap between adjacent batteries, the flow of cooling water between adjacent batteries on the conveyor chain becomes relatively low. This leads to higher temperatures in localized areas of the cooling water tank and the batteries within those areas, thus reducing the cooling effect.

[0006] In response to the aforementioned problem that the cooling effect is reduced due to the high temperature of local areas in the cooling water tank and the surrounding battery, this utility model designs a cooling water tank for batteries. Utility Model Content

[0007] The purpose of this utility model is to provide a cooling water tank for storage batteries. Through the function of the water tank guide component, the fluidity of the cooling water inside the cooling water tank in contact with the surface of the storage battery is improved, thereby increasing its fluidity and the heat dissipation effect of water flow impact. It solves the problem that the cooling effect is reduced due to the high temperature of local areas in the cooling water tank and the storage battery thereon.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model relates to a cooling water tank for a storage battery, comprising a cooling water tank, a conveyor chain, a water tank flow guiding assembly, and a cooling circulating water assembly. The cooling water tank is internally equipped with a conveyor chain; a storage battery is placed on the conveyor chain. The water tank flow guiding assembly includes flow guiding side plates and a flow guiding bottom plate. Flow guiding side plates are arrayed on the inner walls of both sides of the storage battery, and a flow guiding bottom plate is arrayed below the storage battery. A flow-blocking baffle is also fixedly installed below the flow guiding bottom plate. The cooling circulating water assembly includes an inlet pipe and an overflow trough. At least two inlet pipes are fixedly installed on the cooling water tank, and at least two overflow ports are provided on the cooling water tank. An overflow trough is provided outside the overflow ports of the cooling water tank.

[0010] Since batteries typically require tens of minutes or even hours to cool in the water tank, the overall movement speed of the conveyor chain tends to be slow. This results in relatively low flow of cooling water between adjacent batteries on the conveyor chain. The cooling water tank is filled with cooling water to a certain height through the inlet pipe. The overflow port is used to quickly overflow water exceeding the overflow height to ensure that the water level does not exceed the safety level. The conveyor chain transports each battery that is being acidified or has been acidified to the next process position. The water tank flow guiding component aims to ensure that the water flows in and out of contact with the battery surface as much as possible to ensure effective cooling. The cooling circulating water component regulates the flow path of the cooling water in the cooling water tank according to the temperature difference between winter and summer.

[0011] As a preferred technical solution of this utility model, elastic sheets for guiding flow are fixedly connected to the inner sides of the two guide side plates on both sides; rubber strips are fixedly connected to the outer ends of the elastic sheets; the function of the elastic sheets is to guide the cooling water to the two sides of the battery as much as possible, and the rubber strips are used to avoid scratching the two sides of the battery.

[0012] As a preferred technical solution of this utility model, plastic brushes are fixedly connected to the inner sides of the two guide side plates. Since the plastic brushes are relatively soft, they can also disturb the water flow, thereby increasing the cooling water flow to achieve a better heat absorption effect on the battery surface.

[0013] As a preferred technical solution of this utility model, the conveyor chain plate includes a chain plate; the chain plate is uniformly provided with clearance through holes for water flow to pass through; the function of the clearance through holes is that, since the water flow at the bottom of the cooling water tank absorbs less heat and has a relatively low water temperature, the lower temperature cooling water flow is guided through the clearance through holes to the bottom surface of the battery, thereby improving the heat dissipation and cooling effect of the battery.

[0014] As a preferred embodiment of this utility model, the chain plate has a uniform array of flow guiding and heightening plates on its outer surface near the battery; a support plate is fixed to the outer end of the flow guiding and heightening plate; the outer surface of the support plate is in contact with the bottom surface of the battery; the flow guiding and heightening plate is used to increase the gap between the bottom surface of the battery and the chain plate and reduce the contact area between the two, thereby improving the contact area with cooling water and the heat dissipation effect.

[0015] As a preferred embodiment of this utility model, the chain plate has a uniform array of lower guide plates on its inner surface away from the battery; the lower guide plates are used to increase the flow of water from the bottom of the cooling water tank upward to the bottom surface of the battery.

[0016] As a preferred embodiment of this utility model, each overflow tank is fixedly connected to a plurality of water outlet pipes; the plurality of water outlet pipes are arranged vertically; the total flow area of ​​all water outlet pipes in each overflow tank is less than the flow area of ​​one water inlet pipe; the ratio of the total flow area of ​​all water outlet pipes in each overflow tank to the flow area of ​​one water inlet pipe is in the range of 0.2-0.9; the purpose is to ensure that, while keeping the water level difference between the two ends of the water outlet pipes small, the total outflow of all water outlet pipes in each overflow tank is less than the inflow of water in the water inlet pipe, so as to ensure the stability of the water level and prevent it from falling below the height of the overflow outlet; at the same time, it can also achieve the effect of allowing cooling water at different heights inside the cooling water tank to flow out; thereby avoiding the situation where only the cooling water near the water surface in the cooling water tank flows out.

[0017] As a preferred technical solution of this utility model, each overflow tank is provided with an overflow drainage trough at the top. Since there is a water outlet pipe between the overflow tank and the cooling water tank, the water level inside the overflow tank cannot be too low. Otherwise, the water pressure difference between the two ends of the water outlet pipe will be too large, resulting in a too fast flow rate, thereby reducing the water level inside the cooling water tank and causing it to be too low. At the same time, the water level inside the overflow tank cannot continue to rise, which would affect the safe water level. Therefore, the top of the overflow tank is designed with an overflow drainage trough for placing water levels that are too high.

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

[0019] 1. This utility model improves the fluidity of the cooling water in the cooling water tank and the surface of the battery by using the water tank guide component, which has the advantages of increasing fluidity and water flow impact, as well as cooling and heat dissipation.

[0020] 2. This utility model uses the cooling circulating water component to regulate the flow path of the cooling water in the cooling water tank according to the temperature difference of the cooling water in winter and summer; it has the advantage of providing more efficient heat dissipation and cooling effect in summer.

[0021] 3. This utility model utilizes the function of an outlet pipe between the overflow trough and the cooling water tank to allow cooling water at different heights inside the cooling water tank to flow out. This avoids the situation where only the cooling water near the water surface in the cooling water tank flows out and the phenomenon of low heat absorption efficiency of the cooling water, thus ensuring that the cooling water tank is in a relatively good water cooling effect.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0032] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figure 1-5 As shown, this utility model is a cooling water tank for a storage battery, including a cooling water tank 1, a conveyor chain plate 2, a water tank flow guiding assembly 4, and a cooling circulating water assembly 5; the cooling water tank 1 is equipped with a conveyor chain plate 2; a storage battery 3 is placed on the conveyor chain plate 2; the water tank flow guiding assembly 4 includes a flow guiding side plate 401 and a flow guiding bottom plate 402; the cooling water tank 1 has flow guiding side plates 401 arrayed on both sides of the inner wall of the storage battery 3, and the cooling water tank 1 has a flow guiding bottom plate 402 arrayed below the storage battery 3; the cooling water tank 1... A flow-blocking baffle 403 is also fixedly installed below the flow guide plate 402; the cooling water circulation assembly 5 includes an inlet pipe 501 and an overflow trough 502; two inlet pipes 501 are fixedly installed on the cooling water tank 1, and two overflow ports 101 are opened on the cooling water tank 1. An overflow trough 502 is provided outside the overflow ports 101 of the cooling water tank 1; the two inlet pipes 501 are located at the front end and the rear end of the cooling water tank 1, respectively; the two overflow troughs 502 are located at the front end and the front middle part of the cooling water tank 1, respectively.

[0035] In winter, due to the relatively low air and water temperatures, the water temperature inside the cooling water tank 1 differs significantly from the temperature of the battery after acid addition, resulting in a noticeable cooling effect. At this time, only the inlet pipe 501 at the rear end of the cooling water tank 1 and the overflow trough 502 at the front end of the cooling water tank 1 are needed. Initially, the cooling water inside the cooling water tank 1 dissipates heat from the battery 3, which is located at the rear end of the cooling water tank 1 and has a lower heat generation rate, and lowers the temperature of the battery 3 to a minimum, ensuring that it has sufficient temperature rise margin even after being removed from the cooling water tank 1. When the cooling water inside the cooling water tank 1 flows to the front end of the cooling water tank 1, although the water temperature rises slightly, the battery 3 is at a period of rapid heat generation and high internal temperature, and the temperature difference between the two is relatively large, which can also achieve a relatively high heat dissipation and cooling effect.

[0036] During summer, due to the relatively high air and water temperatures, the temperature difference between the battery 3 and its upper temperature limit is relatively small. If the cooling water in the cooling water tank 1 flows from the rear end to the front end, the temperature difference between the two is relatively small and cannot meet the cooling requirements of the battery 3, which generates heat quickly. Therefore, at this time, both inlet pipes 501 located at the front and rear ends of the cooling water tank 1 need to be opened, and only the overflow trough 502 located in the front of the middle of the cooling water tank 1 needs to be opened. At this time, the cooling water at both ends of the cooling water tank 1 flows from both ends to the overflow trough located in the front of the middle. The overflow channel 502 flows, ensuring that the battery, whether in the initial or later stages of acid addition or after acid addition, receives the lowest temperature cooling water for optimal cooling. This not only guarantees the urgent heat dissipation and cooling needs of the rapidly generating battery 3, but also minimizes the temperature of the battery 3 when it is transported to the rear end of the cooling water tank 1, ensuring that the battery 3 has sufficient temperature rise margin even after being removed from the cooling water tank 1. Under normal circumstances, the internal heat generation rate is slow and far from sufficient to raise the internal temperature of the battery 3 to the upper limit or threshold of the safe temperature.

[0037] Since the batteries typically require tens of minutes or even hours to cool in the water tank, the overall movement speed of the conveyor chain plate tends to be slow. This also results in relatively low flow of cooling water between adjacent batteries on the conveyor chain plate. The cooling water tank 1 is filled with cooling water to a certain height through the inlet pipe 501. The overflow port 101 is used to quickly overflow water exceeding the height of the overflow port 101 to ensure that the water level does not exceed the safe level. The conveyor chain plate 2 is used to transport each battery that is being acidified or has been acidified to the next process position. The water tank guide assembly 4 is used to ensure that the water flow impacts and contacts the surface of the battery as much as possible to ensure the cooling and heat dissipation effect. The cooling circulating water assembly 5 is used to adjust the flow path of the cooling water in the cooling water tank 1 according to the temperature difference of the cooling water in winter and summer.

[0038] Among them, such as Figure 5 As shown, the conveyor chain plate 2 includes a chain plate 201; the chain plate 201 is evenly provided with clearance through holes 202 for water flow to pass through; the function of the clearance through holes 202 is that, since the water flow at the bottom of the cooling water tank 1 absorbs less heat and the water temperature is relatively low, the cool water flow with lower temperature is guided through the clearance through holes 202 to the bottom surface of the battery 3, thereby improving the heat dissipation and cooling effect of the battery 3.

[0039] Among them, such as Figure 3 As shown, the chain plate 201 has a uniform array of flow guiding and heightening plates 203 on its outer surface near the battery 3; a support plate 204 is fixed to the outer end of the flow guiding and heightening plate 203; the outer surface of the support plate 204 is in contact with the bottom surface of the battery 3; the flow guiding and heightening plate 203 is used to increase the gap between the bottom surface of the battery 3 and the chain plate 201 and reduce the contact area between the two, thereby improving the contact area with cooling water and the heat dissipation effect.

[0040] Among them, such as Figure 3 As shown, the chain plate 201 has a uniform array of lower guide plates 205 on its inner surface away from the battery 3; the lower guide plates 205 are used to increase the flow of water from the bottom of the cooling water tank 1 upward to the bottom surface of the battery 3.

[0041] Example 2

[0042] A more preferred technical solution based on Embodiment 1 is as follows: Please refer to [link / reference]. Figure 5 As shown, elastic sheets 404 for guiding flow are fixedly connected to the inner sides of the two flow guide side plates 401 on both sides; rubber strips 405 are fixedly connected to the outer ends of the elastic sheets 404; the function of the elastic sheets 404 is to guide the cooling water to the two sides of the battery 3 as much as possible, and the rubber strips 405 are used to avoid scratching the two sides of the battery 3.

[0043] Example 3

[0044] A more preferred technical solution based on Embodiment 1 is as follows: Please refer to [link / reference]. Figure 6 As shown, plastic brushes 406 are fixedly connected to the inner sides of the two guide plates 401. Since the plastic brushes 406 are relatively soft, they can also disturb the water flow, thereby increasing the cooling water flow to better absorb heat on the surface of the battery 3.

[0045] Example 4

[0046] A more preferred technical solution based on Embodiment 1 is as follows: Please refer to [link / reference]. Figure 2As shown, each overflow tank 502 is fixedly connected to the cooling water tank 1 by several outlet pipes 503; the outlet pipes 503 are arranged vertically; the total flow area of ​​all outlet pipes 503 in each overflow tank 502 is less than the flow area of ​​one inlet pipe 501; the ratio of the total flow area of ​​all outlet pipes 503 in each overflow tank 502 to the flow area of ​​one inlet pipe 501 is in the range of 0.2-0.9; the purpose is to ensure that while keeping the water level difference between the two ends of the outlet pipes 503 small, the total outflow of all outlet pipes 503 in each overflow tank 502 is less than the inflow of the inlet pipe 501, so as to ensure the stability of the water level and prevent it from falling below the height of the overflow port 101; at the same time, it can also achieve the effect of allowing cooling water at different heights inside the cooling water tank 1 to flow out; thereby avoiding the situation where only the cooling water near the water surface in the cooling water tank 1 flows out.

[0047] Among them, such as Figure 2 As shown, each overflow trough 502 has an overflow drain trough 504 at its top. Since there is a water outlet pipe 503 between the overflow trough 502 and the cooling water tank 1, the water level inside the overflow trough 502 cannot be too low. Otherwise, the water pressure difference between the two ends of the water outlet pipe 503 will be too large, resulting in a too fast flow rate, which will reduce the water level inside the cooling water tank 1 and cause its water level to be low. At the same time, the water level inside the overflow trough 502 cannot continue to rise, which will affect the safe water level. Therefore, the top of the overflow trough 502 is designed with an overflow drain trough 504 for placing water levels that are too high.

[0048] It is worth noting that in the above system embodiments, the various units are divided according to functional logic, but are not limited to the above division, as long as the corresponding functions can be achieved; in addition, the specific names of each functional unit are only for easy differentiation and are not used to limit the protection scope of this utility model.

[0049] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
