Description

Technical Field

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

[0002] A cooling tower is a device used to cool circulating water, mainly composed of a tower body, fan, packing material, and water distribution system. Its working principle is to spray hot water onto the packing material, forming a water film that exchanges heat with the air, thus cooling the hot water. Cooling towers are widely used in industrial production, central air conditioning, and other fields, effectively reducing the temperature of circulating water and ensuring the normal operation of the system. The water storage device in a cooling tower collects the cooled water, providing a water source for the circulating water pump. The water storage device typically has a certain volume to ensure sufficient water supply during system operation.

[0003] Prior art application number 202121367684.0 discloses a multi-stage cooling tower for dairy products. The cooling tower body has a water storage tank fixedly connected to its top. A cooling assembly is located inside the cooling tower body, including a spiral cooling pipe and a water pump body. The spiral cooling pipe is located inside the cooling tower body, with a supporting vertical mesh inside. A first L-shaped pipe is fixedly connected to the bottom of the spiral cooling pipe, and a second L-shaped pipe is fixedly connected to the top of the spiral cooling pipe. The water pump body is located inside the water storage tank and fixedly connected to it. This design improves the practicality of the multi-stage cooling tower for dairy products and avoids the problem of poor cooling effect and inability to stably and continuously cool dairy processing equipment, as seen in existing multi-stage cooling towers.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: during the use of the water storage tank, the water intake is controlled by the control valve through manual observation, lacking automatic water level monitoring and adjustment, making it difficult to control the water level. If the water level is too high, it is easy to overflow, and if it is too low, it will affect the cooling cycle. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the water storage tank of the cooling tower cannot automatically control the water intake and the water level control is unstable during the water intake process. To this end, we propose a water storage device for cooling towers.

[0006] To achieve the above objectives, this application adopts the following technical solution: a water storage device for a cooling tower, comprising: a cooling tower: a water storage tank is installed at the upper end of the cooling tower, an inlet hopper is provided at the top of the water storage tank, an inlet valve is provided inside the water storage tank, one end of the inlet valve is connected to the inlet hopper, the other end of the inlet valve is connected to a buoyancy component, and an outlet valve and a pumping component are installed at the bottom of the water storage tank.

[0007] Preferably, the water inlet valve includes a valve body, with a water inlet at one end and a piston port at the other end. The water inlet and the piston port are connected in a continuous manner. A water supply pipe is connected to one end of the water inlet, and the water inlet is connected to the water inlet hopper through the water supply pipe. An outlet is provided at the bottom of the valve body, and the outlet is vertically connected to the water inlet.

[0008] Preferably, a piston body is movably mounted inside the piston port, and a piston rod is connected to one end of the piston body. The buoyancy component includes a float, a connecting rod connected to one side of the float, one end of the connecting rod being fixedly connected to the float, and the other end of the connecting rod being connected to the piston rod.

[0009] Preferably, the pumping component includes a water pump, with one end of the water pump connected to a pumping pipe and the other end of the water pump connected to an outlet pipe.

[0010] Preferably, the side wall of the water storage tank is provided with a transparent observation window.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, a float valve is installed, and the valve is opened and closed by mechanical linkage of the float rising and falling with the water level. Water intake control can be completed without external manual intervention. Water is automatically replenished when the water level is low and stopped when the water level is high, ensuring that the water level is always stable within a safe range.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] Reference Figure 1 As shown, this utility model provides a technical solution: a water storage device for a cooling tower, including: a cooling tower 1, a water storage tank 2 installed on the upper end of the cooling tower 1 by screws, a water inlet hopper 3 installed on the top of the water storage tank 2 by welding, and a transparent observation window 4 provided on the side wall of the water storage tank 2, through which the water level in the water storage tank 2 can be observed.

[0023] Reference Figure 2 As shown in this embodiment: a water inlet valve 5 is installed in the water storage tank 2. One end of the water inlet valve 5 is connected to the water inlet hopper 3, and the other end of the water inlet valve 5 is connected to a buoyancy component 6. A water outlet valve 7 and a water pumping component 9 are installed at the bottom of the water storage tank 2. By controlling the water outlet valve 7, the water in the water storage tank 2 can be output to the cooling tower 1 for cooling. By controlling the water pumping component 9, the water that is cooled and returned by the cooling tower 1 can be pumped back into the water storage tank 2 for recycling.

[0024] Reference Figure 3 As shown in this embodiment: the water storage tank 2 includes a water tank shell 21. The bottom of the water tank shell 21 is welded with an inclined bottom 22. One side of the inclined bottom 22 is higher than the other side. A drain outlet 8 is provided at the bottom edge of the lower side of the inclined bottom 22. Water in the water storage tank 2 can be drained through the drain outlet 8, which facilitates the replacement of water in the water storage tank 2.

[0025] Reference Figure 3 As shown in this embodiment: the water pumping component 9 includes a water pump 92, one end of which is connected to a water pumping pipe 91, and the other end of which is connected to a water outlet pipe 93. The water pumping pipe 91 is responsible for transporting the cooling return water to the water pump 92, and then transporting it back to the water storage tank 2 through the water outlet pipe 93.

[0026] Reference Figures 4-5As shown in this embodiment: the water inlet valve 5 includes a valve body 51, one end of which has a water inlet 52 and the other end has a piston port 54. The water inlet 52 and the piston port 54 are connected in a continuous manner. One end of the water inlet 52 is connected to a water supply pipe 55, and the water inlet 52 is connected to the water inlet 3 through the water supply pipe 55. The bottom of the valve body 51 has a water outlet 53, which is vertically connected to the water inlet 52. A piston body 56 is movably installed inside the piston port 54. The piston body 56 can slide inside the valve body 51 along the direction of the water inlet 52. One end of the piston body 56 is fixedly connected to a piston rod 57 by welding.

[0027] Reference Figures 4-5 As shown in this embodiment: the buoyancy component 6 includes a float 61, which is hollow and can move with the rise and fall of the water level. A connecting rod 62 is fixedly connected to one side of the float 61. One end of the connecting rod 62 is fixedly connected to the float 61, and the other end of the connecting rod 62 is rotatably connected to the piston rod 57. When the water level rises, the float 61 floats with the water level and drives the connecting rod 62 to rotate, pushing the piston rod 57 and the piston body 56 to slide along the direction of the water inlet 52. When the water level reaches a certain position, the piston body 56 blocks the water inlet 52 and stops water intake. When the water level drops, the piston body 56 moves towards the piston opening 54, and water can enter again.

[0028] Working principle: The user connects the water source to the water inlet 3, and the water reaches the water inlet 52 through the water supply pipe 55. At this time, the water level in the water storage tank 2 is low, the buoyancy component 6 is tilted downward, and the piston body 56 is close to the piston port 54. Water can enter the water storage tank 2 through the water inlet 52 and the water outlet 53. The maximum water height in the water storage tank 2 can be calculated by the volume of the water circulation channel in the water storage tank 2 and the cooling tower 1. When the water level rises to the preset maximum height, the float ball 61 rises with the buoyancy and pushes the piston body 56 to block the water inlet 52 to stop the water from entering. When the water in the cooling cycle decreases due to consumption during the cooling process, the water level drops, the float ball 61 descends, and the piston body 56 slides back to open the water inlet 52, so that water can be replenished to the water storage tank 2.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
