[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to solve the problem that the traditional cooling tank may only use a single spraying method, resulting in the PVC sheet cooling is not uniform and efficient. At the same time, in the traditional cooling tank design, the temperature of the whole single cooling tank will gradually increase during the continuous operation, thus affecting the cooling effect. Figure 1-4 , this utility provides the following technical solutions:

[0023] A PVC sheet water-cooled cooling tank, comprising a separation cooling tank 1 and a conveyor belt 3, wherein at least two separation cooling tanks 1 are provided, and adjacent separation cooling tanks 1 are interconnected, and the tops of the separation cooling tanks 1 are connected with circulating water pipes 7, and the bottoms of the separation cooling tanks 1 are connected with drain pipes 5, and the ends of the drain pipes 5 away from the separation cooling tanks 1 are connected with cooling water tanks 4, and the cooling water tanks 4 are connected with heat exchangers 6, and the water outlets of the heat exchangers 6 are connected with the circulating water pipes 7, and the cooled water flows into the cooling water tanks 4 through the drain pipes 5, and then heat is exchanged through the heat exchangers 6 to reduce the water temperature, and then the water is recycled, and the temperature of the cooling water is reduced by the heat exchangers 6, so that the recycled water resources are more efficient, and the separation cooling tank 1 A drying tank 2 is connected to one side, and a conveyor belt 3 enters from one side of the separation and cooling tank 1. The separation and cooling tank 1 passes through each separation and cooling tank 1 in turn and enters the interior of the drying tank 2. The conveyor belt 3 extends from the side of the drying tank 2 away from the separation and cooling tank 1 to the outside. By using multiple separation and cooling tanks 1 in series, the cooling area and time of the PVC sheet are increased, and the cooling efficiency is improved. At the same time, the multiple separation and cooling tanks 1 are connected only by the inlet and outlet ports 11, so that the effect of the mutual influence of the cooling temperature environment between the separation and cooling tanks 1 is reduced. When the PVC sheet enters each separation and cooling tank 1 in turn, the temperature environment inside each separation and cooling tank 1 is gradually reduced, so that the cooling effect can be effectively improved.

[0024] In this embodiment, both sides of the separation and cooling tank 1 are provided with inlet and outlet ports 11, and a water guide slope 16 is provided on the inner upper side of the inlet and outlet ports 11. A spray pipe 12 is provided inside the separation and cooling tank 1, and the spray pipe 12 is connected to the circulating water pipe 7. A spray port 13 is provided at the bottom of the spray pipe 12. The bottom of the separation and cooling tank 1 is connected to the drain pipe 5. A water pump 17 is provided on one side of the separation and cooling tank 1. The water inlet end of the water pump 17 is connected to a water guide pipe 15, and the water outlet end of the water pump 17 is connected to a bottom spray pipe 14. The water guide pipe 15 is connected to the inside of the separation and cooling tank 1 from the side, and the bottom spray pipe 14 is connected to the inside of the separation and cooling tank 1. The nozzle of the bottom spray pipe 14 is vertically arranged upward. The combination of the spray pipe 12 and the bottom spray pipe 14 allows the cooling water to be more evenly covered on the surface of the PVC sheet. By spraying and bottom spraying at the same time, the temperature of the PVC sheet can be quickly reduced, the production efficiency is improved, and the cooling effect is improved.

[0025] In this embodiment, the bottom of the drying tank 2 is connected with a water pipe 8, which is connected with the cooling water tank 4. An electric fan 21 is arranged inside the drying tank 2, a heating wire 22 is arranged inside the electric fan 21, a vent 23 is provided on the side of the drying tank 2, a water storage tank 24 is arranged at the bottom of the drying tank 2, the bottom of the water storage tank 24 is connected with the water pipe 8, and a valve 25 is arranged on the water pipe 8. The electric fan 21 and the heating wire 22 in the drying tank 2 can quickly dry the PVC sheet, thereby improving the production efficiency. The water vapor or water droplets generated during the drying process will fall into the water storage tank 24, and then flow back to the cooling water tank 4 through the water pipe 8, thereby realizing the recycling of water resources.

[0026] The working principle of the above content is as follows: the PVC sheet enters the separation cooling tank 1 from one side through the conveyor belt 3. The circulating water pipe 7 guides water from the cooling water tank 4 to the spray pipe 12, and the water is evenly sprayed on the PVC sheet through the spray port 13 to initially cool it. At the same time, the water pump 17 sprays water from the bottom to the PVC sheet through the water guide pipe 15 and the bottom spray pipe 14. Since the nozzle of the bottom spray pipe 14 is vertically upward, the water will splash around after contacting the PVC sheet, increasing the cooling area and effect. The cooled water flows back to the cooling water tank 4 through the drain pipe 5 to achieve the recycling of water resources. The PVC sheet that has been cooled continues to enter the drying tank 2 through the conveyor belt 3. The electric fan 21 starts to work, and the heating wire 22 inside it generates heat to heat the inside of the drying tank 2, thereby drying the PVC sheet. The water vapor or a small amount of water droplets generated during the drying process will drip into the water storage tank 24, and then flow back to the cooling water tank 4 through the water guide pipe 8, further realizing the recovery and recycling of water resources.
