Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane cooling technology, specifically, an overflow stepped zoned cooling water tank. Background Technology

[0002] Waterproof membrane is a core material in building waterproofing projects. Its main production processes include material preparation, impregnation and coating, lamination / sand spreading, cooling and shaping, and rolling and packaging. Among these, cooling and shaping is a critical process affecting the final physical properties, appearance quality, and production energy consumption of the product. In this stage, the high-temperature formed waterproof membrane must undergo effective cooling to reduce its temperature to below 50℃ to ensure that it does not stick together or deform after rolling, and maintains stable dimensional and mechanical properties.

[0003] Currently, the most commonly used cooling device in the industry is an open-type circulating cooling water tank. This device is typically a rectangular container with multiple passively rotating guide rollers inside. The high-temperature roll material passes around these guide rollers submerged in water in an S-shaped path, achieving cooling through heat exchange between the water and the surface of the roll material.

[0004] However, this traditional cooling water tank has gradually revealed several technical bottlenecks in practical applications. For example, the roll material undergoes a violent heat exchange with the cooling water the moment it enters the tank, causing the surface to shrink rapidly while the internal heat is not dissipated in time. This results in uneven cooling rates in different parts of the roll material, generating significant internal stress. This "rapid cooling" effect can easily lead to a decrease in the flatness of the roll material, and even defects such as warping and wrinkles, affecting product quality. Especially for thicker waterproof roll materials, the residual heat in the core is difficult to dissipate, and "arching" can easily occur after winding due to heat accumulation. Furthermore, to achieve a better cooling effect, large amounts of low-temperature tap water or chilled water are usually used for soaking. The cooling water's temperature rises rapidly after absorbing heat from the roll material, and it is often directly discharged, failing to achieve cascaded utilization. This direct-flow cooling method not only consumes a large amount of water resources but also places a heavy burden on the factory's refrigeration system, leading to high production costs.

[0005] Therefore, given the aforementioned deficiencies in existing technologies, there is an urgent need for a well-designed, uniformly efficient, energy-saving, water-saving, and automatically corrective cooling water tank for waterproof membranes, in order to improve product quality, reduce production energy consumption, and ensure the stable operation of the production line. Utility Model Content

[0006] The purpose of this invention is to provide an overflow stepped zoned cooling water tank to solve the problems of excessively rapid cooling of materials in the initial stage of cooling rolls by existing water cooling equipment, resulting in sudden cooling and the need to set up multiple water cooling tanks for gradient temperature control, which leads to excessive water consumption.

[0007] To solve the above problems, the present invention adopts the following technical means: An overflow stepped partitioned cooling water tank includes a water-cooling tank with an open top surface. A vertical first partition plate and a second partition plate are installed inside the water-cooling tank. The first partition plate and the second partition plate sequentially divide the water-cooling tank into a first chamber, a second chamber, and a third chamber along the horizontal material conveying direction. A first raising plate is installed at the top of the first partition plate, and a second raising plate is installed at the top of the second partition plate. The height of the second raising plate is greater than the height of the first raising plate. The height of the side wall of the water-cooling tank near the second raising plate is not lower than the height of the second raising plate. The first chamber between the water-cooling tank and the first partition plate forms a pre-cooling chamber. The second chamber between the first partition plate and the second partition plate serves as the main cooling chamber. The third chamber between the second partition plate and the water-cooling tank serves as a cooling and shaping chamber. The side wall of the water-cooling tank has an inlet pipe communicating with the third chamber and an outlet pipe communicating with the first chamber. The material to be cooled sequentially passes through the first chamber, the second chamber, and the third chamber.

[0008] Preferably, both the first and second heightening plates are wedge-shaped plates, and the horizontal width of the first and second heightening plates gradually decreases from bottom to top along the material's horizontal movement direction.

[0009] Furthermore, the first cavity is provided with a first conveying mechanism, the second cavity is provided with a second conveying mechanism, and the third cavity is provided with a third conveying mechanism. The material to be cooled passes through the first cavity via the first conveying mechanism, through the second cavity via the second conveying mechanism, and through the third cavity via the third conveying mechanism.

[0010] Furthermore, the first conveying mechanism includes a pair of first rollers disposed on the lower side of the first cavity and a second roller and a third roller disposed above the first cavity. The second roller and the third roller are respectively disposed directly above the two first rollers. The second roller is located above the side wall of the water-cooling tank, and the rotation axis of the third roller is located above the first heightening plate.

[0011] Furthermore, a rotating cam is also provided in the first cavity, and the cam part of the rotating cam intermittently abuts against the vertical conveying part for conveying materials.

[0012] Furthermore, the second feeding mechanism includes a pair of fourth rollers disposed on the lower side of the second cavity and a fifth roller and a sixth roller disposed above the second cavity. The fifth roller and the sixth roller are respectively disposed directly above the two fourth rollers. The rotation axis of the fifth roller is located above the first heightening plate, and the rotation axis of the sixth roller is located above the second heightening plate.

[0013] Furthermore, a rotating cam is also provided in the second cavity, and the cam part of the rotating cam intermittently abuts against the vertical conveying part for conveying materials.

[0014] Furthermore, the third feeding mechanism includes a pair of seventh rollers disposed on the lower side of the third cavity and an eighth roller and a ninth roller disposed above the third cavity. The eighth roller and the ninth roller are respectively disposed directly above the two seventh rollers. The rotation axis of the eighth roller is located above the second heightening plate, and the rotation axis of the ninth roller is located above the side wall of the water cooling tank near the second heightening plate.

[0015] Furthermore, a rotating cam is also provided in the third cavity, and the cam part of the rotating cam intermittently abuts against the vertical conveying part for conveying materials.

[0016] This utility model has the following beneficial effects during use: By forming a first, second, and third cavity within the water-cooling tank, and arranging a first and second riser plate, the first, second, and third cavities can be arranged in a progressively deeper layout. Furthermore, ensuring that the bottoms of the first, second, and third cavities are at the same horizontal level, their tops can form a stepped layout from low to high. Thus, when cooling water is pumped into the third cavity through the inlet pipe, once the third cavity is full, the cooling water can overflow from one side of the second riser plate, flowing into the second cavity. Similarly, once the second cavity is full, the cooling water can overflow from one side of the first riser plate, flowing into the first cavity, and then exiting through the outlet pipe connected to the first cavity. This not only macroscopically creates a reverse-flowing and upward-flowing state along the material conveying direction, but also allows for a gradient change in water temperature within the first, second, and third cavities. The water temperature in the first chamber is at its highest since the material has already undergone two cooling cycles in the latter half of the tank. The water temperature in the second chamber, having only cooled the material in the third chamber, is at a relatively good primary cooling temperature. The water temperature in the third chamber, being the newly introduced cooling water, is at its lowest, serving as the final cooling stage for material shaping. This overflow design creates a gradient temperature distribution within the water-cooling tank. The high-temperature material first passes through uniformly heated water at its highest temperature, then through uniformly heated water at a medium temperature, and finally through uniformly heated water at its lowest temperature. This not only prevents sudden cooling during the material's initial cooling process but also ensures proper shaping during cooling in the third chamber. Furthermore, all cooling water in the water-cooling tank overflows from the first chamber, improving equipment continuity and eliminating the need for multiple water-cooling tanks, thus significantly conserving water resources.

[0028] Please refer to Figures 1 to 4 As shown, an overflow stepped partitioned cooling water tank includes a water-cooling tank 1 with an open top surface. A vertical first partition plate 2 and a second partition plate 3 are installed inside the water-cooling tank 1. The first partition plate 2 and the second partition plate 3 sequentially divide the water-cooling tank 1 into a first cavity 4, a second cavity 5, and a third cavity 6 along the horizontal material conveying direction. A first raising plate 7 is installed at the top of the first partition plate 2, and a second raising plate 8 is installed at the top of the second partition plate 3. The height of the second raising plate 8 is greater than the height of the first raising plate 7. The water-cooling tank 1 is close to the second... One end of the heightening plate 8 is higher than the second heightening plate 8. The first cavity 4 between the water-cooling tank 1 and the first partition plate 2 forms a pre-cooling cavity. The second cavity 5 between the first partition plate 2 and the second partition plate 3 serves as the main cooling cavity. The third cavity 6 between the second partition plate 3 and the water-cooling tank 1 serves as a cooling and shaping cavity. The side wall of the water-cooling tank 1 is constructed with an inlet pipe 9 communicating with the third cavity 6 and an outlet pipe 10 communicating with the first cavity 4. The material to be cooled passes through the first cavity 4, the second cavity 5, and the third cavity 6 in sequence.

[0029] In this way, by forming a first cavity 4, a second cavity 5, and a third cavity 6 within the water-cooling tank 1, and by arranging a first riser plate 7 and a second riser plate 8, the first cavity 4, the second cavity 5, and the third cavity 6 can be arranged in a layout with increasing depth. Furthermore, after ensuring that the bottoms of the first cavity 4, the second cavity 5, and the third cavity 6 are at the same horizontal level, their tops can form a stepped layout from low to high. Thus, after cooling water is pumped into the third cavity 6 through the water inlet pipe 9, once the third cavity 6 is full, the cooling water can overflow from one side of the second riser plate 8, flowing into the second cavity 5. Similarly, once the second cavity 5 is full, the cooling water can overflow from one side of the first riser plate 7, flowing into the first cavity 4, and then discharged from the water outlet pipe 10 connected to the first cavity 4. This not only macroscopically creates a reverse-flowing and upward-flowing state along the material conveying direction, but also allows for a gradient change in water temperature within the first cavity 4, the second cavity 5, and the third cavity 6. In this system, the water temperature in the first chamber 4 is at its highest after the material has already undergone two cooling cycles in the latter half of the chamber. The water temperature in the second chamber 5, having only cooled the material in the third chamber 6, is at a relatively good primary cooling temperature. The water temperature in the third chamber 6, being newly introduced cooling water, is at its lowest, serving as the final cooling stage for material shaping. This overflow creates a gradient temperature distribution within the water-cooling tank 1, allowing the high-temperature material to first pass through uniformly high-temperature cooling water, then through uniformly medium-temperature cooling water, and finally through uniformly low-temperature cooling water. This not only prevents sudden cooling during the material's initial cooling process but also ensures proper shaping during cooling in the third chamber 6. Furthermore, all the cooling water in the water-cooling tank 1 overflows from the previous chamber, improving equipment continuity and eliminating the need for multiple water-cooling tanks, thus significantly conserving water resources.

[0030] Specifically, both the first heightening plate 7 and the second heightening plate 8 are wedge-shaped plates, and the horizontal width of the first heightening plate 7 and the second heightening plate 8 gradually decreases from bottom to top along the horizontal movement direction of the material.

[0031] This effectively reduces the situation where cooling water remains at the top of the first riser plate 7 or the second riser plate 8 due to water surface tension during overflow.

[0032] Furthermore, the first cavity 4 is provided with a first conveying mechanism, the second cavity 5 is provided with a second conveying mechanism, and the third cavity 6 is provided with a third conveying mechanism. The material to be cooled passes through the first cavity 4 via the first conveying mechanism, through the second cavity 5 via the second conveying mechanism, and through the third cavity 6 via the third conveying mechanism.

[0033] Furthermore, the first conveying mechanism includes a pair of first rollers 11 disposed on the lower side of the first cavity 4, and a second roller 12 and a third roller 13 disposed above the first cavity 4. The second roller 12 and the third roller 13 are respectively disposed directly above the two first rollers 11. The second roller 12 is located above the side wall of the water cooling tank 1, and the rotation axis of the third roller 13 is located above the first heightening plate 7.

[0034] Meanwhile, a rotating cam 14 is also provided in the first cavity 4, and the cam part of the rotating cam 14 intermittently abuts against the vertical conveying part of the material conveying.

[0035] Furthermore, the second conveying mechanism includes a pair of fourth rollers 15 disposed on the lower side of the second cavity 5, and a fifth roller 16 and a sixth roller 17 disposed above the second cavity 5. The fifth roller 16 and the sixth roller 17 are respectively disposed directly above the two fourth rollers 15. The rotation axis of the fifth roller 16 is located above the first heightening plate 7, and the rotation axis of the sixth roller 17 is located above the second heightening plate 8.

[0036] Similarly, a rotating cam 14 is also provided in the second cavity 5, and the cam part of the rotating cam 14 intermittently abuts against the vertical conveying part for conveying materials.

[0037] Meanwhile, the third conveying mechanism includes a pair of seventh rollers 18 disposed on the lower side of the third cavity 6, and an eighth roller 19 and a ninth roller 20 disposed above the third cavity 6. The eighth roller 19 and the ninth roller 20 are respectively disposed directly above the two seventh rollers 18. The rotation axis of the eighth roller 19 is located above the second heightening plate 8, and the rotation axis of the ninth roller 20 is located above the side wall of the water cooling tank 1 near the second heightening plate 8.

[0038] Furthermore, a rotating cam 14 is provided in the third cavity 6, and the cam part of the rotating cam 14 intermittently abuts against the vertical conveying part for conveying materials.

[0039] In this way, during the material conveying process, the rotating cam 14 continuously disturbs the vertically positioned roll material, causing the cooling water in the first cavity 4, the second cavity 5, and the third cavity 6 to ripple horizontally. This optimizes the overflow of the cooling water and ensures that the temperature of the cooling water in the first cavity 4, the second cavity 5, and the third cavity 6 is relatively uniform, avoiding a situation where the cooling water in the first cavity 4, the second cavity 5, and the third cavity 6 has a lower temperature in the center and a higher temperature near the material.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
