Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a water collecting tank of a high-position water-collecting mechanical ventilation cooling tower. Background Art

[0002] The high-level water collection mechanical ventilation cooling tower is a traditional cooling tower that is equipped with a high-level water collection device. The high-level water collection device is used to intercept the water falling from the bottom of the filler at a high level, thereby reducing the noise caused by the water falling to the bottom of the tower and reducing the water pump head. The high-level water collection device mainly includes a water collection inclined plate and a U-shaped water collection trough. The U-shaped water collection trough is fixedly installed at the lower end of the water collection inclined plate. When the cooling tower is in operation, the water that passes through the filler falls onto the water collection inclined plate, and then flows into the U-shaped water collection trough along the inclined surface. The water that flows into the U-shaped water collection trough flows along the length direction of the U-shaped water collection trough to the water collection box installed on the side wall of the cooling tower, thereby completing the high-level water collection function. The traditional U-shaped water collection trough has an integrated molding structure. For a long U-shaped water collection trough, its structural strength is relatively weak. When the impact force of the water is too large, it is easy for the middle part to be concave, deformed or even broken, which seriously affects the normal operation of the high-level water collection device. In order to avoid this problem, some manufacturers design the U-shaped water collection tank as a split structure, and each part is connected to form a complete U-shaped water collection tank. In this structure, since the lengths of the various parts that constitute the U-shaped water collection tank are relatively short, its structural strength is improved. However, glass glue is usually used to connect the various components. This connection method makes the U-shaped water collection tank non-removable after assembly, which is not conducive to subsequent maintenance. In addition, the bottom wall of the U-shaped water collection tank is in a horizontal state, that is, the height of the bottom wall of the tank is flat at all places, which makes it impossible for the water that falls into the U-shaped water collection tank to flow quickly to the water collection box on the side wall of the cooling tower, thereby slowing down the high-level water collection efficiency of the sprinkler. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in the prior art, the various components of the water collecting trough are difficult to disassemble, which is not conducive to subsequent maintenance. At the same time, the cooling water flow rate in the water collecting trough in a horizontal state is slow, and the water collection efficiency is not high. In view of this, the utility model provides a high-level water collection mechanical ventilation cooling tower water collecting trough which is easy to maintain, has high structural strength and can accelerate the flow of cooling water.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a high-level water collection mechanical ventilation cooling tower water collection tank, including a plurality of water collection tank bodies connected end to end in sequence, connecting flanges are installed at both ends of the water collection tank body, and two adjacent water collection tank bodies are detachably connected through the connecting flanges. The water collection tank body includes a U-shaped groove and a water guide flange, and the water guide flange is fixedly connected to the top of one side of the U-shaped groove. The water guide flange is smoothly transitionally connected to the U-shaped groove, and the heights of the bottom walls of any two adjacent U-shaped grooves along the water flow direction in the U-shaped groove are kept level or decrease in sequence.

[0005] Furthermore, the connecting flange includes a contour plate and a fixing plate connected to each other, the fixing plate is located on one side of the contour plate, the contour plate is consistent with the outer contour of the water collection tank body, the contour plate is fixedly installed on the end of the water collection tank body, and two adjacent water collection tank bodies are detachably connected via the fixing plate.

[0006] Furthermore, the contoured plate is fixedly connected to the sump body by bolts.

[0007] Furthermore, a plurality of fixing holes are provided on the fixing plate.

[0008] Furthermore, the connecting flange is an integrally formed structure and is made of glass fiber reinforced plastic material.

[0009] Furthermore, there are three water collecting trough bodies, and the three water collecting trough bodies are connected end to end in sequence.

[0010] Furthermore, the bottom walls of the three water collecting trough bodies are all at the same height.

[0011] Furthermore, among the three water collecting trough bodies, the bottom wall of the trough of the middle water collecting trough body is a slope, and the bottom walls of the troughs of the water collecting trough bodies on both sides are in a horizontal state.

[0012] Furthermore, the bottom walls of the three water collecting trough bodies are all sloped.

[0013] Furthermore, transverse reinforcing ribs are provided on the inner side walls opposite to the upper end of the U-shaped groove along the length direction of the water collecting trough body, and longitudinal reinforcing ribs are provided on the surface of the water guiding flange for guiding water.

At the same time, two adjacent water collection trough bodies are detachably connected by connecting flanges, which is convenient for subsequent maintenance. In addition, users can meet various usage scenarios of cooling towers by combining various forms of water collection trough bodies. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0024] See also Figure 1-Figure 6The utility model provides a water collecting trough of a high-level water-collecting mechanical ventilation cooling tower, comprising a plurality of water collecting trough bodies 10 connected end to end in sequence, both ends of the water collecting trough body 10 are detachably mounted with connecting flanges 20, two adjacent water collecting trough bodies 10 are detachably connected through the connecting flanges 20, the water collecting trough body 10 comprises a U-shaped groove 11 and a water guiding flange 12, the water guiding flange 12 is fixedly connected to the top of one side of the U-shaped groove 11, the water guiding flange 12 is smoothly transitionally connected to the U-shaped groove 11, and the heights of the bottom walls of any two adjacent U-shaped grooves 11 along the water flow direction in the U-shaped groove 11 are kept level or sequentially reduced.

[0025] When assembling the water collecting tank of the high-position water collecting mechanical ventilation cooling tower of the utility model, the connecting flanges 20 are first installed at both ends of the water collecting tank body 10, and then the connecting flanges 20 at the ends of two adjacent water collecting tank bodies 10 are connected, so that multiple water collecting tank bodies 10 can be combined into a whole. When the cooling tower is in operation, the cooling water passing through the filler is poured on the water collecting inclined plate, and then flows along the inclined surface to the water guide flange 12, and further flows into the U-shaped groove 11. The cooling water entering the U-shaped groove 11 finally flows along the length direction of the U-shaped groove 11 to the water collecting box on the side wall of the cooling tower. When each water collecting trough body 10 is in a horizontal state, the water in the water collecting trough body 10 will flow to both sides respectively, and finally flow into the two water collecting tanks on both sides of the cooling tower. This arrangement of the water collecting trough body 10 is suitable for the use scenario where there are water collecting tanks on both sides of the cooling tower; when the heights of the bottom walls of any two adjacent U-shaped grooves 11 are successively reduced, the bottom wall of the entire water collecting trough body 10 is generally in an inclined state. At this time, the cooling water in the U-shaped groove 11 flows from high to low into the water collecting tank. This arrangement of the water collecting trough body 10 is suitable for the use scenario where there is a water collecting tank on only one side of the cooling tower. The specific arrangement method to be adopted can be decided by the user according to the specific needs of the user.

[0026] As a preferred embodiment, there are three water collecting tank bodies 10, and the three water collecting tank bodies 10 are connected end to end in sequence. Figure 4 In a specific embodiment, the heights of the bottom walls of the three water collecting trough bodies 10 are all level with each other, and the bottom of the water collecting trough is in a horizontal state as a whole. When working, the cooling water can flow to both sides along the length direction of the water collecting trough. At this time, it is suitable for the use scenario of two water collecting tanks arranged relatively on the cooling tower.

[0027] See also Figure 5In another specific embodiment, among the three water collecting trough bodies 10, the bottom wall of the trough of the middle water collecting trough body 10 is a slope, and the bottom walls of the two water collecting trough bodies 10 on both sides are in a horizontal state. When the cooling water flows, it will flow from the water collecting trough body 10 on the side of the higher bottom wall through the water collecting trough body 10 with a slope, and finally flow quickly to the water collecting trough body 10 on the side of the lower bottom wall. At this time, it is suitable for the use scenario where there is a water collecting tank on only one side of the cooling tower.

[0028] See also Figure 6 In another specific embodiment, the bottom walls of the three water collecting trough bodies 10 are all sloped, so that the trough walls of the water collecting trough are inclined as a whole. During operation, the cooling water will flow from the higher side of the bottom wall to the lower side of the bottom wall, and finally flow quickly through the three water collecting trough bodies 10 from high to low. At this time, it is also suitable for the use scenario where only one side of the cooling tower has a water collecting tank.

[0029] Please refer again Figure 1-3 In this embodiment, the connecting flange 20 includes a profiling plate 21 and a fixing plate 22 connected to each other. The fixing plate 22 is located on one side of the profiling plate 21. The profiling plate 21 is consistent with the outer contour of the water collecting tank body 10. The profiling plate 21 is fixedly mounted on the outer wall of the end of the water collecting tank body 10. When connected, the fixing plate 22 is fixedly connected to the end of the water collecting tank body 10 through the profiling plate 21, and two adjacent water collecting tank bodies 10 are detachably connected through the fixing plate 22. In addition, since the profiling plate 21 is consistent with the outer contour of the water collecting tank body 10, the profiling plate 21 fits the outer wall of the water collecting tank body 10. In this way, when the profiling plate 21 is fixed to the end of the water collecting tank body 10, the profiling plate 21 can be used as a reinforcing rib plate, which is conducive to enhancing the structural strength of the end of the water collecting tank body 10 and ensuring the connection reliability between the two adjacent water collecting tank bodies 10.

[0030] As a preferred embodiment, the contour plate 21 is fixedly connected to the sump body 10 by bolts 30 .

[0031] As a preferred embodiment, a plurality of fixing holes 221 are formed on the fixing plate 22 , and the fixing holes 221 are used to install fixing parts such as bolts, so as to fix the two fixing plates 22 together.

[0032] In this embodiment, the water collecting tank body 10 is an integrated structure, which is convenient for processing and also helps enterprises to control production costs. In addition, the water collecting tank body 10 is made of glass fiber reinforced plastic material.

[0033] In addition, the connecting flange 20 is an integrally formed structure and is made of a glass fiber reinforced plastic material, which has good corrosion resistance, can prevent oxidation and corrosion, and extend the service life.

[0034] In order to improve the structural strength of the water collecting trough body 10, transverse reinforcing ribs 13 are provided on the inner side walls opposite to the upper end of the U-shaped groove 11, and the transverse reinforcing ribs 13 are arranged along the length direction of the water collecting trough body 10.

There are multiple longitudinal reinforcing ribs 14, and the multiple longitudinal reinforcing ribs 14 are arranged at intervals along the axial direction of the water collecting trough body 10.

[0035] The utility model discloses a high-level water-collecting mechanical ventilation cooling tower water collection tank, and designs the water collection tank as a split structure composed of a plurality of water collection tank bodies 10. The length of the water collection tank body 10 is relatively short, and the structural strength is increased, thereby avoiding the occurrence of concave deformation and breakage when the impact force of water spraying is too large. At the same time, two adjacent water collection tank bodies 10 are detachably connected by a connecting flange 20, which is convenient for subsequent maintenance. In addition, the user can meet various usage scenarios of the cooling tower by combining various forms of water collection tank bodies 10.
