Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to an automatic water volume adjustment device for a cooling tower water distributor. Background Technology

[0002] Crossflow cooling towers have a large cooling water volume and wide application, making them a widely used heat dissipation device for refrigeration units in many industrial enterprises and commercial sites, and also one of the key components of refrigeration systems. Existing cooling tower water distributors mainly consist of a water distribution tray, an inlet pipe, and an inlet regulating valve. Numerous water distribution holes are opened at the bottom of the water distribution tray, whose function is to ensure that cooling water flows evenly onto the cooling tower packing below, achieving heat dissipation through heat exchange with the laterally flowing air.

[0003] Because the water distribution holes are small, scale or moss in the cooling water can clog them, reducing the amount of water dripping. Since the total water output from the inlet pipe is adjusted manually by a valve, failure to clear debris from the holes or adjust the valve in time can cause water to overflow from the distribution tray, potentially spilling from around the distributor and wasting cooling water. Furthermore, cooling towers are typically located on rooftops, making inspection and adjustment difficult, frequently resulting in significant water waste and sometimes even leaks or safety hazards to electrical equipment. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an automatic water volume adjustment device for cooling tower water distributors, which solves the problem of cooling water waste caused by overflow of water distribution pan in the prior art.

[0005] This utility model solves the above-mentioned technical problems through the following technical means: an automatic water volume adjustment device for a cooling tower water distributor, including a water distribution plate for communicating with a water inlet pipe, a float assembly at the outlet end of the water inlet pipe, the float assembly including an inner cover and a float body adapted to the inner cover, an arc-shaped inner cover at the bottom of the inner cover, water distribution buffer holes evenly distributed on the arc-shaped inner cover, the float body being located between the arc-shaped inner cover and the liquid surface of the water distribution plate, and moving up and down with the change of the liquid level of the water distribution plate to control the amount of water output at the outlet end of the water inlet pipe.

[0006] Optionally, the diameter of the float is less than or equal to the diameter of the arc-shaped inner cover. When the float moves upward with the liquid level in the distribution pan, the distance between the float and the arc-shaped inner cover decreases, and the water flow rate at the outlet end of the inlet pipe decreases; when the float moves downward with the liquid level in the distribution pan, the distance between the float and the arc-shaped inner cover increases, and the water flow rate at the outlet end of the inlet pipe increases. The float moves up and down with the change in liquid level in the distribution pan, and the water flow rate at the outlet end of the inlet pipe is adjusted in real time by the change in the gap with the arc-shaped inner cover.

[0007] Optionally, the outlet end of the water inlet pipe is connected to a flange, and the float assembly is connected to the water inlet pipe via the flange. This facilitates the disassembly of the float assembly and cleaning of the water distribution buffer hole.

[0008] Optionally, the bottom of the inner cover is further provided with a circumferentially distributed, downwardly extending grid, which is used to prevent the float from detaching from the arc-shaped inner cover and moving outward.

[0009] Optionally, the water inlet pipe is equipped with a water inlet regulating valve. The water inlet regulating valve controls the total amount of water entering the water inlet pipe.

[0010] Optionally, the bottom of the water distribution tray is provided with several evenly arranged strip-shaped protrusions, and each strip-shaped protrusion has a plurality of water distribution holes evenly distributed on it. Placing the water distribution holes on the strip-shaped protrusions can reduce the formation of scale.

[0011] Optionally, the bottom of the water distribution plate is provided with an overflow seat having an overflow hole. When the liquid level is high, cooling water flows out from the overflow hole, which alleviates the risk of water overflowing from the periphery of the water distribution plate to a certain extent.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model sets a float assembly at the outlet of the water inlet pipe. The float in the float assembly moves up and down with the change of liquid level in the water distribution plate. The water flow at the outlet of the water inlet pipe is adjusted in real time by the change of the gap with the arc-shaped inner cover. When the liquid level is low, the water flow is increased and when the liquid level is low, the water flow is decreased, ensuring the stability of the liquid level in the water distributor and effectively preventing water overflow and waste of water resources.

[0014] 2. This utility model has a simple structure and is easy to install. It controls the water inflow through a float, without any other moving mechanisms, which effectively prevents the failure of conventional mechanical structures due to corrosion. At the same time, it does not use any additional energy, making it safe, energy-saving, and environmentally friendly. Attached Figure Description

[0020] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can understand the advantages and effects of this utility model from the content disclosed in this specification. It should be noted that the illustrations provided in the following embodiments are for illustrative purposes only and represent schematic diagrams, not actual pictures. They should not be construed as limiting the utility model. To better illustrate the embodiments of this utility model, some components in the figures may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the figures for those skilled in the art.

[0021] In the figures of this utility model embodiment, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper", "lower", "left", "right", "front", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figure, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.

[0022] like Figures 1-4 As shown, this utility model discloses an automatic water volume adjustment device for a cooling tower water distributor, including a water distribution plate 2 for communicating with a water inlet pipe 1. A float assembly is provided at the outlet end of the water inlet pipe 1. The float assembly includes an inner cover 11 and a float 12 adapted to the inner cover 11. An arc-shaped inner cover 111 is provided at the bottom of the inner cover 111. Water distribution buffer holes 112 are evenly distributed on the arc-shaped inner cover 111. The float 12 is located between the arc-shaped inner cover 111 and the liquid surface of the water distribution plate 2, and moves up and down with the change of the liquid level of the water distribution plate 2 to control the amount of water output at the outlet end of the water inlet pipe 1.

[0023] In this embodiment, specifically, the diameter of the float 12 is less than or equal to the diameter of the arc-shaped inner cover 111. When the float 12 moves upward with the liquid level of the water distribution plate 2, the distance between the float 12 and the arc-shaped inner cover 111 decreases, and the water flow rate at the outlet end of the water inlet pipe 1 decreases; when the float 12 moves downward with the liquid level of the water distribution plate 2, the distance between the float 12 and the arc-shaped inner cover 111 increases, and the water flow rate at the outlet end of the water inlet pipe 1 increases. The minimum water flow rate is determined by the difference in diameter between the two. When the two are equal, the water flow can be almost completely shut off.

[0024] In this embodiment, to facilitate the disassembly of the float assembly and cleaning of the water distribution buffer hole, a flange 13 is connected to the outlet end of the water inlet pipe 1, and a flange structure is also provided on the top of the inner cover 11. The flange structure is of similar size to the flange 13 and is connected by threads, thereby allowing the float assembly to be detachably connected to the water inlet pipe 1 through the flange 13.

[0025] In this embodiment, the bottom of the inner cover 11 is also provided with a circumferentially distributed downward extending grid 113. The grid 113 is used to prevent the float 12 from detaching from the arc-shaped inner cover 111 and moving outward. The grids 113 are circumferentially spaced, and the circumference formed by all the grids 113 makes the float 12 only able to move up and down within the grid 113.

[0026] In this embodiment, the inlet pipe 1 is equipped with an inlet regulating valve 14 for manually adjusting the total amount of water entering the inlet pipe 1. The bottom of the water distribution tray 2 has several evenly arranged strip-shaped protrusions 21, each with a plurality of water distribution holes 22. The placement of the water distribution holes 22 on the strip-shaped protrusions 21 helps reduce scale formation at the water distribution holes 22, thereby reducing clogging. The bottom of the water distribution tray 2 is equipped with an overflow seat 23 with an overflow hole 231, which can mitigate the risk of water overflowing from the periphery of the water distribution tray to a certain extent.

[0027] The working principle of this utility model is as follows:

[0028] When using the automatic water volume adjustment device of this utility model, the water inlet regulating valve 14 is manually rotated as needed to fix the initial water volume of the water inlet pipe 1. By setting a float assembly at the outlet of the water inlet pipe 1, the float 12 in the float assembly moves up and down with the change of liquid level in the water distribution plate 2. The water volume at the outlet of the water inlet pipe 1 is adjusted in real time by the change of the gap between the float 12 and the arc-shaped inner cover 111. When the liquid level is low, the water volume is automatically increased; when the liquid level is low, the water volume is automatically decreased, ensuring the stability of the liquid level in the water distributor and effectively preventing water overflow and waste of water resources.

[0029] During this process, the water distribution buffer hole 112 on the arc-shaped inner cover 111 disperses the water flow from the outlet of the water inlet pipe 1, buffers the water pressure, and prevents the float 12 from failing to float properly due to excessive force.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
