Description

Technical Field

[0001] This utility model belongs to the field of cable production technology, and specifically relates to a temperature control device for cooling water in a catenary crosslinking production line. Background Technology

[0002] Currently, most catenary cross-linking production lines used for producing 35kV and below medium-voltage cross-linked polyethylene insulated cables (hereinafter referred to as cross-linked cables) are long-length catenary cross-linking production lines. During the production of cross-linked cables, a large amount of cooling water is used. However, the temperature of the cooling water after heat exchange is relatively high, requiring cooling to facilitate recycling and conserve water resources. Existing technologies utilize water tanks for natural cooling of the cooling water, but this is inefficient. Other technologies use cooling towers to cool the cooling water, but existing cooling towers cannot control the temperature of the cooling water, making them inconvenient and unable to meet the production needs of enterprises.

[0003] Therefore, improvements are urgently needed. Utility Model Content

[0004] To address the aforementioned deficiencies in the existing technology, this utility model provides a temperature control device for cooling water in a catenary crosslinking production line, comprising a water tank and a cooling tower. A first inlet pipe is connected to one side of the water tank, and a second inlet pipe and an outlet pipe are connected to the other side of the water tank. The first inlet pipe is connected to the cooling water pipeline of the catenary crosslinking production line. An air outlet is provided at the top of the cooling tower, and an exhaust fan is installed at the air outlet. A spray pipe is installed below the exhaust fan and is connected to the outlet pipe. Multiple spray heads are installed at the bottom of the spray pipe. A packing layer is installed below the spray pipe, and a perforated plate for support is installed at the bottom of the packing layer. An air inlet is provided at the bottom of the cooling tower, and a filter screen is installed at the air inlet to filter impurities and dust from the air. An outlet is provided at the bottom of the cooling tower and is connected to the second inlet pipe.

[0005] Optionally, water pumps are installed on the first inlet pipe, the second inlet pipe, and the outlet pipe of the water tank, and a valve is installed at the outlet of the cooling tower.

[0006] Optionally, a thermometer is installed inside the pool to detect the water temperature.

[0007] Optionally, the water tank is equipped with a stirring mechanism, which includes a crossbeam, a geared motor, a main stirring shaft, and two auxiliary stirring shafts. The crossbeam is fixed above the water tank by a mounting bracket. The geared motor is installed above the crossbeam. The main stirring shaft is vertically installed in the water tank. The top end of the main stirring shaft passes through the crossbeam and is connected to the output shaft of the geared motor. The main stirring shaft and the crossbeam are rotatably connected. Several mounting seats are spaced apart from top to bottom on the main stirring shaft. Four strip-shaped blades are evenly distributed on each mounting seat. The two auxiliary stirring shafts are located on the left and right sides of the main stirring shaft. The top ends of the two auxiliary stirring shafts are rotatably connected to the crossbeam. The two auxiliary stirring shafts are connected to the main stirring shaft through a transmission device. The transmission device is located at the top of the auxiliary stirring shaft and away from the water surface. Multiple square blades are connected to each auxiliary stirring shaft.

[0008] Specifically, the stirring mechanism can promote the mixing of hot and cold water in the pool, thereby improving heat exchange efficiency.

[0009] Optionally, the strip blades are inclined, and the angle between the strip blades and the horizontal plane is 30°-60°.

[0010] Specifically, it can improve mixing efficiency.

[0011] Optionally, the transmission device adopts a belt pulley drive structure.

[0012] Optionally, the air induced device includes a drive motor and a rotating shaft. The drive motor is fixed at the air outlet of the cooling tower by a fixed bracket. The rotating shaft is vertically arranged below the drive motor. The top of the rotating shaft is connected to the output shaft of the drive motor. Several fan blades are installed at the bottom of the rotating shaft.

[0013] Optionally, the cooling tower is equipped with a water collector and a level gauge. The water collector is located between the air intake device and the spray pipe to absorb water droplets in the air and reduce moisture loss. The level gauge is located below the air inlet to detect the water level at the bottom of the cooling tower.

[0014] This invention also includes other components that enable the temperature control device for cooling water in a catenary crosslinking production line to function properly; all of these are conventional techniques in the field. Furthermore, any devices or components not specified in this invention employ conventional techniques in the field, such as drive motors, water pumps, geared motors, thermometers, and level gauges.

[0015] The working principle of this invention is as follows: During use, hot water from the cooling water pipes of the catenary crosslinking production line flows into the water tank. When the thermometer detects that the water temperature in the tank exceeds 30°C, the water pump on the outlet pipe is started to draw the hot water into the spray pipe and spray it out through the spray head. At the same time, the drive motor is started to drive the rotating shaft to rotate, which in turn drives the fan blades to rotate, introducing cold air from the outside into the tower through the air inlet at the bottom of the cooling tower. Using the principle of aerodynamics, the sprayed hot water is cooled by heat exchange. The packing layer can increase the contact time between the water droplets and the cold air, improving the heat exchange efficiency and effect. After being cooled by heat exchange, the water droplets gather at the bottom of the cooling tower and flow back into the water tank through the second inlet pipe. The reduction motor is started to drive the main stirring shaft to rotate, which in turn drives the two auxiliary stirring shafts and the strip blades to rotate, mixing and stirring the hot and cold water in the water tank, accelerating the heat exchange efficiency. When the thermometer detects that the water temperature is below 25°C, the water pump is turned off.

[0016] The beneficial effects of this utility model are that, through the water tank and cooling tower, not only can the cooling water of the suspension crosslinking production line be cooled and cooled, but its temperature can also be controlled to keep it within the required temperature range to meet the production needs of enterprises. At the same time, by using the stirring mechanism, the heat exchange efficiency between hot and cold water in the water tank can be accelerated and the cooling time can be shortened.
