Description

Technical Field

[0001] This utility model relates to the field of cooling tower equipment technology, and in particular to a push-pull type conical cooling tower water distribution device. Background Technology

[0002] With the rapid development of modern urban construction, hotels, large shopping malls, commercial office buildings, subway stations, and other buildings have sprung up in large numbers, and central air conditioning systems have been widely used. As a key supporting equipment for central air conditioning, the installation location of cooling towers is often limited by space, thus increasing the requirements for the adaptability of cooling tower structures.

[0003] The water distribution tray is one of the core components of a cooling tower, and its performance directly affects the cooling tower's heat dissipation efficiency. In existing technologies, to meet the needs of multi-water distribution system cooling towers or side-discharge cooling towers with interlayer installation, a "drawer-type water distribution tray" (such as...) has been designed. Figure 1 As shown in the image, this structure has significant drawbacks: it is quite heavy (approximately 25kg for a 900mm x 900mm size), making it inconvenient to pull out for cleaning or nozzle replacement, and posing a serious safety hazard, especially when working at heights above 3 meters. Therefore, there is an urgent need to optimize and improve the existing water distribution tray structure. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to overcome the shortcomings of the existing drawer-type water distribution tray, such as large weight, inconvenient operation and poor safety, and to provide a push-pull type conical cooling tower water distribution device.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A push-pull type conical cooling tower water distribution device includes: a water distribution tank frame, a push-pull type conical water distribution tray and a guide rail assembly;

[0007] The push-pull conical water distribution tray has an oblique conical tray structure, with a bottom plane width greater than the top and a cone angle of α; conical protrusions are provided on the left and right sides of the push-pull conical water distribution tray respectively;

[0008] The guide rail assembly includes an upper guide rail and a lower guide rail, which are respectively fixed to the upper and lower inner sides of the water distribution tank frame. The upper guide rail has a trapezoidal boss at its tail end, and the lower guide rail is inclined with the inclination angle being the same as the cone angle α.

[0009] The trapezoidal boss at the tail end of the upper guide rail is used to cooperate with the conical boss to press the sealing strip.

[0010] Furthermore, the value of α ranges from 1.5° to 2°.

[0011] Furthermore, the sealing strip is fixed to the bottom surface of the upper guide rail, with a thickness of 2mm.

[0012] Furthermore, the height of the conical boss is 2.5mm, and a gap of 0.5-1.0mm is maintained between it and the upper guide rail.

[0013] Furthermore, the water tank frame is assembled from a front panel, a rear panel, a left side panel, a right side panel, and a middle guide rail structure to form a closed cavity; wherein, the middle guide rail structure includes a middle guide rail and a middle guide rail cover plate, the middle guide rail cover plate is fixed to the top of the middle guide rail, and the middle guide rail is arranged parallel to the left side panel and the right side panel.

[0014] Furthermore, the water distribution tank frame is provided with a water distribution tray inlet / outlet flange at the inlet / outlet port, and is equipped with a stainless steel buckle. One end of the stainless steel buckle is connected to the water distribution tray inlet / outlet flange, and the other end is detachably connected to the front panel of the push-pull conical water distribution tray.

[0015] Furthermore, the push-pull conical water distribution tray is equipped with multiple variable flow nozzles, which are evenly distributed along the length of the push-pull conical water distribution tray.

[0016] Furthermore, the upper and lower guide rails are connected to the left and right side plates by screws, with the screws and nuts forming a locking structure.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] like Figure 2 The diagram shows the structure of a push-pull conical water distribution tray, which includes a water distribution tank frame, a push-pull conical water distribution tray 5, and a guide rail assembly.

[0032] The push-pull conical water distribution tray 5 has an oblique conical tray structure, with its bottom plane width being greater than its top width and a cone angle of α; the push-pull conical water distribution tray 5 is provided with conical protrusions 13 on its left and right sides respectively;

[0033] The guide rail assembly includes an upper guide rail 7 and a lower guide rail 8. The upper guide rail 7 and the lower guide rail 8 are respectively fixed to the upper and lower inner sides of the water distribution tank frame. The tail end of the upper guide rail 7 is provided with a trapezoidal boss 14. The lower guide rail 8 is inclined, and the inclination angle is consistent with the cone angle α.

[0034] The trapezoidal boss 14 at the tail end of the upper guide rail 7 is used to cooperate with the conical boss 13 to press the sealing strip 11; the value of α is in the range of 1.5°-2°. When the push-pull conical water distribution tray 5 enters the water distribution tank, ensure that the push-pull conical water distribution tray 5 has sufficient space (height h) to slide between the upper guide rail 7 and the lower guide rail 8, and avoid the push-pull conical water distribution tray 5 contacting the upper guide rail 7 and the lower guide rail 8 to avoid friction, which could cause the push-pull conical water distribution tray 5 to jam (e.g. Figure 3 This reduces friction between the push-pull conical water tray 5 and the upper and lower guide rails, making its movement smoother.

[0035] Because there is a gap between the push-pull conical water distribution tray 5 and the upper guide rail 7, the sealing performance of this type of push-pull conical water distribution tray 5 is relatively poor, and water will leak into the gap, causing uneven water distribution. Therefore, a sealing strip 11 with a thickness of 2mm is fixed to the bottom surface of the upper guide rail 7 to seal the gap between the push-pull conical water distribution tray 5 and the upper guide rail 7 to prevent water leakage (e.g., Figure 4 (As shown).

[0036] When the sealing strip 11 is installed, the push-pull conical water distribution tray 5 will rub against the sealing strip 11 when it enters the upper and lower guide rails 7 and 8, potentially damaging the sealing strip 11. Therefore, a conical boss 13 is machined on each of the left and right sides of the push-pull conical water distribution tray 5 as a limit. The height of the conical boss 13 is 2.5mm, and a gap of 0.5-1.0mm is maintained between it and the upper guide rail 7 to ensure smooth movement of the push-pull conical water distribution tray 5. However, even after the push-pull conical water distribution tray 5 is fully inserted into the water distribution tank, if the conical boss 13 still abuts against the upper guide rail 7, meaning there is still a gap between the push-pull conical water distribution tray 5 and the sealing strip 11, a seal cannot be achieved. Therefore, a trapezoidal boss 14 must be machined at the tail end of the upper guide rail 7 so that the conical boss 13 enters the trapezoidal boss 14. In this way, the push-pull conical water distribution tray 5 will tightly press against the sealing strip 11, achieving a seal and ensuring uniform water distribution (e.g., Figure 5 (As shown).

[0037] The water tank frame is assembled from a front panel 1, a rear panel 2, a left side panel 3, a right side panel 4, and a middle guide rail structure to form a closed cavity; wherein, the middle guide rail structure includes a middle guide rail 10 and a middle guide rail cover plate 9, the middle guide rail cover plate 9 is fixed to the top of the middle guide rail, and the middle guide rail 10 is arranged parallel to the left side panel 3 and the right side panel 4.

[0038] The water distribution tank frame has a water distribution tray inlet / outlet flange 12 at its inlet / outlet port, equipped with a stainless steel buckle 15. One end of the stainless steel buckle 15 is connected to the water distribution tray inlet / outlet flange 12, and the other end is detachably connected to the front panel 1 of the push-pull conical water distribution tray 5. When the push-pull conical water distribution tray 5 is fully pushed into the water distribution tank, it must be fixed to the water distribution tray inlet / outlet flange 12 and sealed with a sealing strip 11. The buckle 15 method of fixing is simple and quick, reduces labor intensity, and better ensures the safety of operators (e.g., ...). Figure 6 (As shown).

[0039] The push-pull conical water distribution plate 5 is equipped with multiple variable flow nozzles 6, which are evenly distributed along the length of the push-pull conical water distribution plate 5.

[0040] The upper guide rail 7, the lower guide rail 8, the left side plate 3, and the right side plate 4 are connected by screws, and the screws and nuts form a locking structure.

[0041] like Figure 7 The diagram shown is an exploded view of the conical water distribution tray. The installation method is as follows: The left side plate 3 is fixed to the left side of the front panel 1 and rear panel 2 using screws 16 and nuts 17. The right side plate 4 is fixed to the right side of the front panel 1 and rear panel 2 using screws 16 and nuts 17. The upper cover plate 9 of the middle guide rail and the middle guide rail 10 are fixed to the middle of the front panel 1 and rear panel 2 using screws 16 and nuts 17. This completes a basic water distribution tank structure. Then, the upper guide rail 7 and lower guide rail 8 are fixed to the upper and lower screw holes of the left, middle, and right side plates respectively using screws 16 and nuts 17. This creates a closed cavity for installing the push-pull conical water distribution tray 5, restricting its movement within this cavity. When cleaning or replacing the nozzle 6, simply pull out the push-pull conical water distribution tray 5, remove the nozzle 6 for cleaning or replacement, and then reinstall the nozzle 6. Finally, push the push-pull conical water distribution tray 5 back into the cavity and lock it with the latch. This method is easy and convenient, ensuring no leakage inside the water distribution tray, uniform water distribution, reducing the weight of the water distribution tray, lowering the workload of operators, and ensuring personal safety.

Any person skilled in the art to which this utility model pertains may make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in this utility model, but the patent protection scope of this utility model shall still be determined by the scope defined in the appended claims.
