Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a water-saving cooling tower with antifreeze function. Background Technology

[0002] Water-saving cooling towers are industrial devices designed to reduce water consumption while efficiently achieving cooling functions, and are widely used in industrial production and refrigeration systems. They primarily save water by optimizing the heat exchange process and improving water recycling methods. In terms of heat exchange, some water-saving cooling towers use high-efficiency heat dissipation packing to increase the contact area and time between water and air, improving heat dissipation efficiency and reducing the amount of water consumed for cooling. Others utilize specially designed water distribution systems to ensure even water distribution and improve heat exchange efficiency. Regarding recycling, they are equipped with comprehensive water recovery devices to collect water droplets carried during evaporation, avoiding water waste. Some also incorporate water purification equipment to remove impurities and salts from the water, allowing the circulating water to be used for extended periods and reducing the need for replenishment. Compared to traditional cooling towers, water-saving cooling towers significantly reduce water consumption, saving costs for businesses and reducing environmental impact, which is of great significance for achieving sustainable industrial development.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: In the process of cooling industrial hot water, the industrial hot water flows from top to bottom through the packing material and is cooled by the heat exchange of the circulating air. However, in the cold winter, the temperature of the hot water is relatively low when it flows to the lower end of the packing material, which can easily lead to freezing and thus affect the overall cooling effect of the cooling tower. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the lower end of the packing material in the existing technology is prone to freezing. To address this, we propose a water-saving cooling tower with antifreeze function.

[0005] To achieve the above objectives, this application adopts the following technical solution: a water-saving cooling tower with antifreeze function, including a tower body, a base fixedly installed at the lower end of the tower body, a water inlet pipe installed at the bottom inner side of the base, a packing material arranged inside the tower body passing through the middle of the water inlet pipe, and a fan installed at the upper end of the tower body.

[0006] A support frame is installed on the upper inner side of the base. A temperature sensor and a heating plate are installed on the upper end of the support frame. Both the temperature sensor and the heating plate are electrically connected to a controller installed on the outside of the tower body. The temperature sensor and the heating plate are located at the lower end of the packing.

[0007] Preferably, a partition is provided between the tower body and the base, with the upper end of the partition fixedly connected to the tower body and the lower end of the partition fixedly connected to the base, and multiple through holes are provided on the partition.

[0008] Preferably, at least two temperature sensors are provided.

[0009] Preferably, the water inlet pipe includes a horizontal pipe, a vertical pipe, and a spray pipe. The vertical pipe is installed at the output end of the horizontal pipe, and the spray pipe is installed at the output end of the vertical pipe. The vertical pipe passes through the middle of the packing material, and the spray pipe is located at the upper end of the packing material.

[0010] Preferably, the input end of the horizontal tube extends through the outer side of the base, and the output end of the horizontal tube is inserted into the middle of the base.

[0011] Preferably, a motor is installed in the middle of the base, and a drive gear is provided at the drive end of the motor. The drive gear meshes with a driven gear provided on the lower outer side of the vertical tube.

[0012] Preferably, a bearing is installed at the lower end of the vertical pipe, with the inner ring of the bearing fixedly connected to the vertical pipe and the outer ring of the bearing fixedly connected to the output end of the horizontal pipe.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In this invention, during cold winters, the lower end of the packing is prone to freezing due to low water temperature. When the temperature between the packing and the base monitored by the temperature sensor is lower than the threshold, the controller installed on the tower body receives the information transmitted by the temperature sensor that is electrically connected to it. The controller then controls the heating plate that is electrically connected to it to heat the packing, thereby preventing the lower end of the packing from freezing due to continuous temperature drop, thus enabling the water-saving cooling tower to operate stably and efficiently.

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. 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.

[0023] Reference Figure 1 As shown, this utility model provides a technical solution: a water-saving cooling tower with antifreeze function, including a tower body 1, a base 2 fixedly welded to the lower end of the tower body 1, and a certain gap between the tower body 1 and the base 2. This allows air to be replenished from the gap when the fan 6 installed at the upper end of the tower body 1 exhausts air outward. Specifically, the fan 6 exhausts air to the upper end of the tower body 1, while the outside air at the gap replenishes the air inward, thereby forming an air circulation inside the tower body 1. However, in order to prevent floating objects such as large plastic bags from entering the tower body 1, preferably, a partition 11 with through holes is provided at the gap. The upper and lower ends of the partition 11 can be connected to the tower body 1 or the base 2 by screws or welding.

[0024] Reference Figure 2 As shown, industrial hot water is transported to the upper part of the tower body 1 through the inlet pipe 3 installed on the base 2, and drips onto the upper part of the packing 5 installed by screws on the inner side of the tower body 1 by spraying. The industrial hot water flows downward from the upper part of the packing 5, and then exchanges heat with the circulating cold air to achieve a cooling effect. Finally, it flows out from the lower part of the packing 5 and into the interior of the base 2, and is discharged from the drain pipe 4 installed on the base 2 by screws or welding. It is then recycled to complete the cooling work of the entire water-saving cooling tower.

[0025] Reference Figures 1-3 As shown, in cold winter, the lower end of the packing 5 is prone to freezing due to low water temperature. When the temperature sensor 9 detects that the temperature between the packing 5 and the base 2 is below the threshold, such as 2°C, the controller 12 installed on the tower body 1 receives the information transmitted by the temperature sensor 9, which is electrically connected to it. The controller 12 controls the heating plate 8, which is electrically connected to it, to heat the packing 5, thereby preventing the lower end of the packing 5 from freezing due to continuous temperature drop, so that the water-saving cooling tower can operate stably and efficiently.

[0026] Furthermore, to facilitate the installation and support of the temperature sensor 9 and the heating plate 8, a support frame 7 is installed on the upper inner side of the base 2. Both the temperature sensor 9 and the heating plate 8 are installed on the support frame 7. In order to improve the accuracy of temperature monitoring, 2-4 temperature sensors 9 can be set.

[0027] Furthermore, refer to Figures 4-5 As shown, the water inlet pipe 3 consists of a horizontal pipe 31, a vertical pipe 32, and a spray pipe 33. The input end of the horizontal pipe 31 passes through the outside of the base 2, while the output end is inserted into the middle of the base 2, so that the horizontal pipe 31 can be stably supported. The lower end of the vertical pipe 32 is inserted into the upper middle of the base 2, and the middle part passes through the middle of the packing 5. The upper end of the vertical pipe 32 is connected to the spray pipe 33, which is located at the upper end of the packing 5. The process hot water enters from the horizontal pipe 31, and then passes through the vertical pipe 32 and is sprayed from inside the spray pipe 33 onto the upper end of the packing 5.

[0028] Furthermore, to facilitate the even spraying of process hot water onto the upper end of the packing 5 by the spray pipe 33, a driven gear 34 is installed on the outer side of the lower end of the vertical pipe 32. The driven gear 34 is driven to rotate by the driving gear 35 installed on one side. The driving gear 35 is driven to rotate by the motor 36 installed in the middle of the base 2. Thus, the motor 36 drives the driving gear 35 to rotate, which in turn drives the driven gear 34 to rotate, causing the vertical pipe 32 to rotate. The vertical pipe 32 drives the spray pipe 33 to rotate along the axis of the packing 5, which can evenly spray the hot water onto the packing 5 and improve the cooling effect.

[0029] Furthermore, to facilitate the rotation of the vertical pipe 32 while it is flowing with water, a bearing 37 is installed at the lower end of the vertical pipe 32. The radial outer circumferential surface of the inner ring of the bearing 37 is fixedly connected to the radial outer circumferential surface of the vertical pipe 32, while the lower side of the outer ring of the bearing 37 is fixedly connected to the output end of the horizontal pipe 31. This allows the vertical pipe 32 to rotate while conveying water.

[0030] 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.
