[0002] In industrial cooling systems, cross-flow cooling towers as a common heat exchange equipment, its performance and efficiency are crucial to the operation of the whole system. The bottom of the traditional cross-flow cooling tower suspended center cylinder outlet structure usually adopts the welded design, such as Figure 1 The wedge-shaped center cylinder is welded, both ends are provided with welded center cylinder support beams for supporting the top of the center cylinder, and the lower part is provided with a center cylinder support beam supporting the bottom of the center cylinder. However, this traditional welded center cylinder has many problems: on the one hand, the welding workload is large, which needs to consume a lot of manpower and time, increases the production cost and production cycle; on the other hand, stress concentration is easy to occur in the welding process, which reduces the stability and reliability of the structure, affects the service life of the cooling tower. In addition, the welded center cylinder uses more materials and has a larger weight, which not only increases the material cost, but also brings inconvenience to the installation and transportation of the cooling tower. SUMMARY

[0003] In view of the above problems, the utility model provides a sheet metal wedge center cylinder, which aims to realize the lightweight, high strength and high sealing property of the center cylinder through sheet metal bending and bolt connection processes, and reduce the production cost and improve the production efficiency.

[0004] To achieve the above purpose, the utility model adopts the technical scheme of:

[0005] A sheet metal wedge center cylinder, comprising a side plate, a main plate and an inclined plate of a sheet metal structure, the side plate, the main plate and the inclined plate jointly forming a wedge-shaped center cylinder main body; the upper end of the side plate is bent outward to form a flange, forming a sheet metal beam, and the lower side edge and the end part are both provided with a second side flange; the four edges of the main plate are provided with C-shaped flanges bent outward, and a circular hole is formed in the main plate for installing an outlet flange and a blowdown opening; the four edges of the inclined plate are provided with flanges bent outward, and the inclined plate is provided with a protruding strip protruding inward; the components are connected by bolts, and the connection is pasted with butyl tape to improve the sealing property.

[0006] The beneficial effects of the above technical solution are: the sheet metal wedge-shaped center cylinder adopts a sheet metal structure, and through the bending and flanging design of each component, the structure is lightweight and the strength is improved. The sheet metal beam design at the upper end of the side plate replaces the traditional welded center cylinder support beam, which not only reduces the welding workload, but also reduces the material cost. The main flange design on the main plate enhances the support strength of the main plate, and provides a stable foundation for the installation of the water outlet flange and the blowdown port. The convex strip design on the inclined plate not only improves the rigidity of the inclined plate, but also effectively prevents the formation of vortex in the center cylinder, reduces the probability of air entering the water, and ensures the operating efficiency of the cooling tower. Each component is connected by bolts, which is convenient and fast to install. The connection is pasted with butyl tape to improve the sealing performance and prevent water leakage. The overall structure design is reasonable, the production efficiency is high, and the production cost is greatly reduced.

[0007] As a further improvement of the above scheme, the lower flange of the inclined plate is installed in close contact with the inner wall of the main plate, and butyl tape is filled in the middle.

[0008] The beneficial effects of the above technical solution are: the lower flange of the inclined plate is installed in close contact with the inner wall of the main plate, and butyl tape is filled in the middle, which further enhances the sealing performance and structural strength of the bottom of the center cylinder. This design forms a tight connection between the inclined plate and the main plate, effectively preventing water leakage from the connection, and improving the overall stability of the structure, ensuring that the center cylinder can withstand certain water pressure and external forces during use, prolonging the service life.

[0009] As a further improvement of the above scheme, the first side flange of the inclined plate is installed in close contact with the inner wall of the side plate, and butyl tape is filled in the middle.

[0010] The beneficial effects of the above technical solution are: the first side flange of the inclined plate is installed in close contact with the inner wall of the side plate, and butyl tape is filled in the middle, which realizes the tight connection between the inclined plate and the side plate, enhances the structural strength and sealing performance of the side of the center cylinder. This design not only improves the overall stability of the center cylinder, preventing water leakage from the side connection, but also effectively disperses the impact force of the water flow on the side of the center cylinder, further prolonging the service life of the center cylinder.

[0011] As a further improvement of the above scheme, the main flange on both sides of the main plate is installed in close contact with the inner wall of the side plate, and butyl tape is filled in the middle.

[0012] The beneficial effects of the above technical solution are: the main flange on both sides of the main plate is installed in close contact with the inner wall of the side plate, and butyl tape is filled in the middle, which forms a firm connection between the main plate and the side plate, improving the overall structural strength and sealing performance of the center cylinder. This design not only enhances the load-bearing capacity of the center cylinder, but also effectively prevents water leakage from the connection between the main plate and the side plate, ensuring the reliability and stability of the center cylinder during use.

[0013] As a further improvement of the above scheme, the main flange at the upper end of the main plate and the upper flange of the inclined plate and the metal beam are connected with the bottom of the cooling tower water collecting basin, and the connection is filled with butyl tape.

[0014] The beneficial effects of the above technical solution are that the connection of the main flange at the upper end of the main plate, the upper flange of the inclined plate and the metal beam with the bottom of the cooling tower water collecting basin and the filling of butyl tape achieve the tight connection between the center cylinder and the cooling tower water collecting basin, improving the stability and sealing of the overall structure. This design not only ensures the accurate installation position of the center cylinder in the cooling tower, but also effectively prevents water leakage from the connection, and at the same time, through the supporting action of the metal beam, the carrying capacity and anti-deformation ability of the center cylinder are enhanced, ensuring the normal operation of the cooling tower.

[0015] As a further improvement of the above scheme, the bottom of the center cylinder is V-shaped.

[0016] The beneficial effects of the above technical solution are that the V-shaped design of the bottom of the center cylinder can effectively reduce the vortex and turbulence generated inside the center cylinder, reducing the probability of air entering the water, thereby improving the cooling efficiency and operation stability of the cooling tower. At the same time, the V-shaped bottom is beneficial to the concentration and discharge of bottom stains, and the impurities in the center cylinder can be cleaned more conveniently through the drain, keeping the inside of the center cylinder clean and further improving the operation efficiency and service life of the cooling tower.

[0017] As a further improvement of the above scheme, the water outlet flange includes an inner flange and an outer flange; the inner flange and the outer flange are respectively installed at the circular hole positions of the inner and outer walls of the main plate and are fixed by being clamped with bolts.

[0018] The beneficial effects of the above technical solution are that the water outlet flange adopts a split design of an inner flange and an outer flange, which are respectively installed at the circular hole positions of the inner and outer walls of the main plate and are fixed by being clamped with bolts. This installation method is not only simple to operate, but also ensures the tight connection between the water outlet flange and the main plate, improves the sealing, and effectively prevents water leakage. At the same time, the split design makes the installation and replacement of the water outlet flange more flexible, reducing maintenance costs. In addition, the cooperation of the inner flange and the outer flange enhances the structural strength of the water outlet, which can withstand a large water pressure, ensuring the stability and reliability of the cooling tower under high load operation, and further improving the performance and service life of the entire metal wedge-shaped center cylinder.

[0019] Compared with the traditional welded center cylinder, the metal wedge-shaped center cylinder has many significant advantages:

[0020] In structural design, the light weight and high strength of each component are realized through sheet metal bending and flanging processes, the welding workload and material usage are reduced, and the production cost and labor cost are reduced. In terms of sealing performance, butyl tape is used to seal the connections, effectively preventing water leakage and improving the reliability and stability of the center cylinder. In terms of function, the convex strip design on the inclined plate and the V-shaped bottom design effectively reduce the generation of water vortex and turbulent flow, reduce the entry of air into the water, improve the operating efficiency of the cooling tower, and facilitate the discharge of bottom stains, keeping the center cylinder clean. Overall, the utility model has the advantages of simple structure, convenient installation, excellent performance, high practical value and market competitiveness, and provides a more advanced, efficient and economical solution for the design and manufacture of the center cylinder of the cooling tower.
