Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to a high-level water collection tank. Background Technology

[0002] Currently, most water collection tanks on the market are made of fiberglass reinforced plastic (FRP) and manufactured using a hand lay-up molding process. Fiberglass, with its corrosion resistance, lightweight, and high strength, meets basic usage requirements to a certain extent. However, with increasing environmental protection requirements, growing demand for large-scale production, and stricter product quality standards, the traditional manufacturing process of fiberglass water collection tanks has revealed the following technical bottlenecks and industry pain points:

[0003] 1. Harsh production environment: The hand lay-up molding process relies on manual labor to apply resin and lay up fiber reinforcement materials (such as fiberglass cloth), which generates a large amount of volatile organic compounds (VOCs), especially harmful gases such as styrene, which seriously endanger the health of operators.

[0004] 2. Outdated Technology and Low Efficiency: Current processes rely entirely on manual operation. Statistics show that the production efficiency of traditional hand lay-up technology is less than 30% of that of injection molding, severely restricting capacity expansion. Furthermore, the uncontrollable nature of manual operation makes it difficult to guarantee product quality. More significantly, the water collection tank is molded as a single piece; if local structural damage, uneven sealing surfaces, or internal cavity deformation are detected after demolding, the entire tank must be scrapped, resulting in a material waste rate as high as 15%–20%.

[0005] 3. High processing difficulty for complex structures: When dealing with deep grooves, irregular curved surfaces, or thin-walled designs, the hand lay-up process is prone to weakening structural strength due to insufficient fiber lay-up or insufficient resin flowability. In addition, insufficient mold precision and manual adjustment errors will further reduce the dimensional stability of the product and affect the sealing performance during on-site installation.

[0025] Please see Figure 1 The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0026] It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are only used to complement the content disclosed in the specification for those skilled in the art to understand and read, and are not intended to limit the conditions under which this utility model can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

The term “connection,” unless otherwise specified, includes both direct and indirect connections.

[0028] To avoid confusion with this utility model, some technical features known in the art have not been described.

[0029] like Figure 1 As shown, this embodiment provides an elevated water collection tank, which is injection molded from modified PP. It includes a body 10 and a flange 20. The body 10 is an upward-opening tank with a U-shaped cross-section for holding water. The flange 20 has an arc-shaped cross-section and is fixedly connected to one side wall of the body 10. The flange 20 can be used to form a water collection ramp for a cooling tower. The body 10 and flange 20 are respectively injection molded from modified PP and then assembled to form the elevated water collection tank.

[0030] This embodiment adopts a split water collection tank structure, which can separately injection mold the body 10 with a deep cavity and the arc-shaped flange 20. This avoids the design of complex molds, reduces the difficulty and cost of mold processing, avoids the problem of difficult demolding, and avoids mold damage. It can also reduce the risk of overall scrap due to local defects, which not only improves the yield and production efficiency, but also facilitates the transportation and modular maintenance of the split structure.

[0031] To facilitate the vertical connection of the body 10 and the flange 20 and to enable waterproofing, the body 10 and the flange 20 can be fixedly connected using flanges. Specifically, flange edges 11 can be formed on both sides of the open end of the body 10 and on one end of the flange 20. The flange edges 11 have evenly distributed bolt holes. The flange 20 is fixedly connected to one side wall of the body 10 via the flange edges 11 and bolts. The flange edges 11 are flat flanges with a semi-circular groove offset 20mm from the center line of the bolt holes, using a long, circular cross-section sealing strip. When the body 10 and the flange 20 are vertically connected, the long, circular cross-section sealing strip is embedded in the semi-circular groove, and tightening the bolts ensures a tight seal between the body 10 and the flange 20.

[0032] To achieve a sealed connection between two adjacent elevated water collection tanks, a first flange 12 is provided at both ends of the body 10, the shape of which matches the cross-sectional shape of the body 10; a second flange 21 is provided at both ends of the flange 20, the shape of which matches the cross-sectional shape of the flange 20. Multiple bolt holes are evenly arranged on the first flange 12 and the second flange 21. Both the first flange 12 and the second flange 21 are designed for airtight sealing, using flat flanges. A semi-circular groove is opened 20mm off the centerline of the bolt holes, and a long strip of circular cross-section sealing strip is used. When two adjacent elevated water collection tanks are joined, the long strip of circular cross-section sealing strip is embedded in the semi-circular groove, and after tightening the bolts, a tight seal between the two adjacent elevated water collection tanks is ensured.

[0033] It should be noted that the bottom ends of the body 10 have a certain slope, that is, the heights of the first flanges 12 at the two ends are different, so that the two ends of the body 10 have a natural height difference. Therefore, according to the use needs, the flanges 20 can be installed on different side walls of the body 10 to form a left part or a right part.

[0034] Furthermore, the first flange 12 is perpendicular to the ground and is U-shaped with a certain thickness. The bottom of the first flange 12 is flat, which can form a natural base, so that the body 10 can stand stably on the ground, and its thickness can ensure the strength of the support.

[0035] To ensure a smooth interior for the body 10, facilitating smooth water flow and minimizing resistance, and considering ease of demolding during injection molding, longitudinal reinforcing ribs 13 are provided only on the outer surface of the body 10. These longitudinal reinforcing ribs 13 are evenly spaced, and their cross-sections are protruding arc shapes, ensuring smooth demolding while also reinforcing the body 10.

[0036] To enhance the suspension bearing capacity of the high-level water collection tank, through holes for suspension components can be reserved at the opening position of the main body 10 at a standard interval of 2 meters. At the same time, reinforcing members 14 are provided around the through holes to provide solid reinforcement for the through holes.

[0037] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
