DETAILED DESCRIPTION

It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of 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.

[0023] See also Figures 1 to 5 The utility model provides a technical solution: a closed cooling tower, comprising: a casing 1, a fan 2 is symmetrically fixedly installed on the top of the casing 1, a water collecting chamber 13 is provided in the lower part of the casing 1, and a water collector 12 is installed in the upper part of the casing 1; a spray assembly 6, the spray assembly 6 comprises a circulation pipe 1 61, the circulation pipe 1 61 is fixedly installed in the upper part of the casing 1, a plurality of evenly distributed branch pipes 64 are fixedly installed on the outer periphery of the circulation pipe 1 61, and a plurality of evenly distributed nozzles 65 are fixedly installed on the lower part of the outer periphery of the branch pipe 64, a spray pump 62 is fixedly installed at the bottom end of the circulation pipe 1 61, a circulation pipe 2 63 is fixedly installed on the end of the spray pump 62 away from the circulation pipe 1 61, and the end of the circulation pipe away from the water spray pump is fixedly installed on the rear side of the casing 1 and is connected with the water collecting chamber 13, after the high-temperature liquid enters the cooler 10 through the input pipe 5, the spray assembly 6 sprays The pump 62 can pump the water in the water collecting chamber 13 into the branch pipe 64 through the circulation pipe 1 and the circulation pipe 2 63. Since the branch pipe 64 is equipped with a nozzle 65 at the lower part, the nozzle 65 can spray water evenly onto the cooler 10, so that the high-temperature liquid in the cooler 10 can be cooled. The outer surface of the cooler 10 is wrapped with a PVC heat exchange layer filler to improve the heat dissipation efficiency. The high-temperature liquid after cooling will be output through the output pipe 7. During the cooling process, the high-temperature water vapor generated will move upward with the cooperation of the fan 2. At this time, the high-temperature water vapor will pass through the water collector 12. The water collector 12 can prevent the occurrence of water flying, reduce the loss of liquid water and medicine, and at the same time maintain the ecological environment and save water resources. The water after spraying can enter the water collecting chamber 13 through the filtering mechanism 8, which is conducive to the recycling of water resources.

[0024] A mounting bracket 9 is fixedly installed in the middle upper part of the casing 1, a cooler 10 is fixedly installed in the middle of the mounting bracket 9, an output pipe 7 is fixedly installed on the upper part of the cooler 10, an input pipe 5 is fixedly installed on the lower part of the cooler 10, a pressure gauge 11 is fixedly installed on the upper part of the outer periphery of the input pipe 5, a base 4 is fixedly installed at the bottom end of the casing 1, a spray pump 62 is fixedly installed in the middle of one side of the top of the base 4, a grid 3 is symmetrically installed at the lower front side of the casing 1, and the input pipe 5 allows the high-temperature liquid to enter the cooler 10. Since there are multiple curved pipes in the cooler 10, the high-temperature liquid will be evenly distributed. Through the pipeline, in conjunction with the spray assembly 6, the high-temperature liquid in the cooler 10 can be cooled down, and the grid 3 on the front side of the casing 1 can interact with the external environment. Under the action of the fan 2, the ambient air enters the cooling tower through the grid 3, which is beneficial to the cooling of the high-temperature liquid in the cooler 10, and a pressure gauge 11 is installed on the input pipe 5. The pressure gauge 11 can detect the pressure of the high-temperature liquid in the input pipe 5 to prevent abnormal pressure from affecting the normal use of the cooling tower, and the high-temperature liquid after cooling will be discharged from the cooling tower through the output pipe 7.

[0025] The filter mechanism 8 is arranged at the lower part of the casing 1. The filter mechanism 8 includes a mounting frame 82. The mounting frame 82 is fixedly mounted at the lower part of the casing 1. A collection box 83 is slidably mounted in the middle part of the mounting frame 82, and a handle is fixedly mounted in the middle part of the rear side of the collection box 83. A plurality of evenly distributed filter holes 81 are provided at the bottom end of the mounting frame 82 and the lower part of the collection box 83. When the temperature in the spray assembly 6 is cooled, water will fall into the collection box 83. Since the filter holes 81 are provided in the collection box 83 and the mounting frame 82, the filter holes 81 can filter the cooled water, which can prevent the impurities such as scale generated inside the cooling tower from falling into the water collecting chamber 13 when the cooling tower is used for a long time, and the spray pump 62 is blocked, affecting the normal use of the water circulation.

[0026] During the actual use of the system, the staff connects the input pipe 5 to the external equipment. At this time, the high-temperature liquid will enter the cooler 10 through the input pipe 5. Then, the spray pump 62 in the spray assembly 6 can collect the water in the water chamber 13 through the circulation pipe 1 61 and the circulation pipe 2 63 and then into the branch pipe 64. At this time, the nozzle 65 at the bottom of the branch pipe 64 will spray the water evenly into the cooler 10. At this time, the low-temperature water can cool the high-temperature liquid in the cooler 10. The water vapor generated during the cooling process will enter the water collector 12 with the cooperation of the fan 2. The water collector 12 can prevent the occurrence of water flying, reduce the loss of liquid water and medicine, maintain the ecological environment and save water resources. The water after spraying can pass through the collection box 83 and the mounting frame 82 in the filtering mechanism 8, so that the water after spraying can be filtered to avoid impurities mixed into the water during the cooling process, which affects the normal use of the spray assembly 6. After entering the water collecting chamber 13, the spray assembly 6 can recycle water resources.
