DETAILED DESCRIPTION

[0014] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0015] Combined with Figure 1 , 2As shown, a cooling water recovery device for a cooling water tank for BTTZ cable production includes a water storage tank 1, wherein the water storage tank 1 is divided into a water supply chamber 2 and a water return chamber 3, and a water supply pump 4 connected to the water supply chamber 2 is provided outside the water storage tank 1, and a water return pump 5 connected to the water return chamber 3 is provided, and a connecting pipe 6 for connecting the water supply chamber 2 and the water return chamber 3 is provided, and a connecting solenoid valve 6a is provided on the connecting pipe 6; a water supply pipe 7, wherein both ends of the water supply pipe 7 are respectively connected to the cooling water tank and the water supply pump 4, and a water supply solenoid valve 7a is provided on the water supply pipe 7 ; A return pipe 8, both ends of which are connected to the cooling water tank and the return water pump 5, respectively, and a return water solenoid valve 8a is provided on the return pipe 8; a refrigeration mechanism 9, which is used to cool the water in the water supply chamber 2; a water temperature sensor, which has two water temperature sensors, which are respectively arranged in the cooling water tank and the water supply chamber 2; a control host 10, which is respectively electrically controlled and connected to the water supply solenoid valve 7a, the return water solenoid valve 8a, the communication solenoid valve 6a, the water supply pump 4, the return water pump 5, and the refrigeration mechanism 9;

[0016] It should be noted that when the cable is water-cooled, the cooling water in the cooling water tank 11 will evaporate, so the cooling water in the cooling water tank 11 needs to be replenished in time; in addition, an isolation cover can also be added to the cooling water tank 11 to prevent a large amount of evaporated water vapor from overflowing, thereby reducing the loss of cooling water.

[0017] The refrigeration mechanism 9 includes an evaporator 9a, a condenser, a compressor, and an expansion valve. The evaporator 9a is located in the water supply chamber 2. The evaporator 9a includes a plurality of heat exchange components 9b connected in series. The heat exchange components 9b include a fixing frame 9c and a plurality of heat exchange tubes 9d arranged on the fixing frame 9c and connected in series in a spiral shape.

[0018] The cooling water recovery device also includes a water level sensor, of which there are two, which are respectively arranged in the cooling water tank and the water supply cavity 2;

[0019] It should be noted that

[0020] When the water level sensor in the cooling water tank 11 detects that the water level is insufficient, the feedback is sent to the control host 10, and the control host 10 opens the water supply solenoid valve 7a and the water supply pump 4 to supply water to the cooling water tank 11 until the water level requirement is met;

[0021] At this time, if the water level sensor in the water supply chamber 2 detects that the water level is insufficient, the connecting solenoid valve 6a is opened to allow the cooling water in the return water chamber 3 to enter the water supply chamber 2. If the water level is still insufficient, the control host 10 will alarm, indicating that additional water needs to be added to the cooling water tank 11.

[0022] When additional water is added, the connecting solenoid valve 6a is opened, the return solenoid valve 8a is opened, and the return pump 5 works to return the cooling water in the cooling water tank 11 to the water supply chamber 2 until the water level in the water supply chamber 2 reaches the standard; at the same time, additional water can be slowly added to the cooling water tank 11 until the cooling water level in the cooling water tank 11 reaches the standard.

[0023] The water inlet end of the water return pipe 8 is provided with a filter.

[0024] The outside of the water storage tank 1 is provided with a plurality of heat sinks.

[0025] When the cooling water recovery device is working,

[0026] The water temperature sensor in the cooling water tank 11 detects that the water temperature inside is too high and feeds back to the control host 10;

[0027] The control host 10 controls the water supply solenoid valve 7a, the water supply pump 4, the return water solenoid valve 8a, and the return water pump 5 to open, and the cooling water tank 11 takes in low-temperature cooling water while recovering high-temperature cooling water until the water temperature reaches the standard;

[0028] Afterwards, the connecting solenoid valve 6a is opened, and the high-temperature cooling water in the return water chamber 3 flows into the water supply chamber 2. The water temperature sensor in the water supply chamber 2 detects that the water temperature is too high and feeds back to the control host 10. The control host 10 controls the refrigeration mechanism to work until the water temperature in the water supply chamber 2 meets the standard.
