[0032] Water softening refers to a series of chemical or physical treatment processes to reduce the hardness of water, that is, to remove or reduce calcium and magnesium ions to a certain extent. This treatment method can make the water purer and softer, and because the proportion of calcium and magnesium ions in the softened water is low, it is not easy to produce scale.

[0033] Referring to Figure 1 , the arrow shows the water flow direction, and the utility model embodiment provides a kind of plastic film blowing cooling system, including cooling device, soft water device 400 and monitoring component, cooling device includes refrigeration component 200 and air supply component 300, refrigeration component 200 and air supply component 300 are connected by pipeline, refrigeration component 200 and air supply component 300 jointly manufacture cold wind to cool plastic film;Wherein refrigeration component 200 is used to cool water, to reduce the temperature of water, air supply component 300 is provided with the pipeline that can be supplied with cold water and carries out heat exchange, air supply component 300 is also provided with air blowing structure to blow the air after being cooled by cold water to plastic film;After being cooled by refrigeration component 200, water is transported to air supply component 300, air and cold water are exchanged in air supply component 300, and the air after being cooled is blown to plastic film by the air blowing structure of air supply component 300;Soft water device 400 is connected with cooling device by pipeline, and the role of soft water device 400 is to soften hard water and provide softened water for cooling device;Monitoring component includes first pressure monitoring module 500, and first pressure monitoring module 500 is connected with the water outlet end of soft water device 400 by pipeline to monitor the outlet pressure of soft water device 400, whether the blockage occurs in soft water device 400 is judged by the outlet pressure of soft water device 400, whether the work of soft water device 400 is normal is judged, so as to maintain soft water device 400 in time.

[0034] According to some embodiments of the application, the cooling device further comprises a heat dissipation assembly 100, and the soft water device 400, the first pressure monitoring module 500, the heat dissipation assembly 100 and the refrigeration component 200 are connected in sequence by pipelines. The heat dissipation assembly 100 is used to naturally dissipate heat and cool the water at a higher temperature. The water cooled by the heat dissipation assembly 100 is transported to the refrigeration component 200, which can reduce the energy consumption of the refrigeration component 200 for water cooling and save resources.

[0035] The soft water device 400 is used to soften the tap water, that is, to remove or reduce the calcium and magnesium ions in the tap water to a certain extent. The softened water is not easy to produce scale in the pipeline of the cooling system, so as not to easily cause the copper pipe to be blocked, maintain the long-term efficient operation of the equipment, and ensure the plastic film production capacity and production quality. The heat dissipation assembly 100 is used to pre-cool the water, thereby saving energy consumption. The monitoring assembly is used to monitor the cooling system in real time, so as to timely find problems or risks in the operation of the cooling system and timely eliminate them, thereby ensuring the normal operation of the cooling system and the production safety and efficiency. Since the pipeline of the cooling system is not easy to produce scale, the refrigeration assembly 200 and the air supply assembly 300 can be operated for a long time and efficiently, thereby avoiding the problems of high refrigeration energy consumption and low heat exchange efficiency caused by the pipeline scale blockage, and further saving energy consumption.

[0036] As a preferred scheme, the heat dissipation assembly 100 is a cooling tower, the refrigeration assembly 200 is an industrial water chiller, and the air supply assembly 300 is an air supply cabinet. The cooling tower, the industrial water chiller, and the air supply cabinet are sequentially connected through pipelines.

[0037] According to some embodiments of the present application, the monitoring assembly further comprises a second pressure monitoring module 510, which is arranged at the water inlet end of the soft water device 400. The second pressure monitoring module 510 is used to monitor the water inlet pressure of the soft water device 400 and compare it with the monitoring value of the first pressure monitoring module 500, so as to more accurately judge the working state of the soft water device 400. At the same time, it is avoided that the first pressure monitoring module 500 monitors the low pressure due to the low water inlet pressure of the soft water device 400, and thus misjudges the working state of the soft water device 400.

[0038] Further, the soft water device 400 comprises a filter core assembly 410, which comprises a resin softening filter. The resin softening filter is used to soften hard water. When the hard water passes through the resin filter core, the calcium and magnesium ions will exchange with the sodium ions on the resin beads. Since the charge of the calcium and magnesium ions is stronger than that of the sodium ions, they will preferentially replace the sodium ions and combine with the resin. After ion exchange, the calcium and magnesium ions in the water are removed, and the water quality is softened.

[0039] It can be understood that in other embodiments, the filter core assembly 410 further comprises one or more of an activated carbon filter, a quartz sand filter, and a manganese sand filter, so as to further improve the filtering capacity of the filter core assembly 410 and reduce the entry of silt, metal chips, or other harmful chemical substances into the heat dissipation assembly 100.

[0040] Further, the soft water device 400 further comprises a first pressurizing module 420, which is arranged at the water inlet end of the soft water device 400. Specifically, the first pressurizing module 420 is a pressurizing pump, the water inlet of the pressurizing pump is connected to the tap water pipeline, and the water outlet of the pressurizing pump is connected to the water inlet of the filter core assembly 410, so as to provide the tap water to the filter core assembly 410 for processing after pressurizing.

[0041] According to some embodiments of the present application, the monitoring assembly further comprises a first water hardness monitoring module 520, which is arranged at the connecting pipeline between the heat dissipation assembly 100 and the refrigeration assembly 200. The first water hardness monitoring module 520 is used to monitor the water hardness of the internal pipeline of the cooling device, so as to find the abnormal condition of the water hardness in the cooling device in time.

[0042] Further, the monitoring assembly further comprises a second water hardness monitoring module 530, which is arranged at the connecting pipeline between the soft water device 400 and the heat dissipation assembly 100. The second water hardness monitoring module 530 is used to monitor the water hardness of the water outlet end of the soft water device 400, so as to monitor whether the soft water device 400 is invalid in real time, and to process and avoid the hard water entering the heat dissipation assembly 100 in time.

[0043] According to some embodiments of the present application, the air supply assembly 300 is connected to the heat dissipation assembly 100 through a second pressurizing module 310 and a pipeline, so as to send the water heated by the air supply assembly 300 back to the heat dissipation assembly 100 for recycling. Specifically, the second pressurizing module 310 is a one-way hydraulic pump, and the water heated by the heat exchange of the air supply assembly 300 can be pumped back to the heat dissipation assembly 100 by the one-way hydraulic pump, so as to be recycled.

[0044] Further, a first stop valve 120 is arranged at the connecting pipeline between the first pressure monitoring module 500 and the heat dissipation assembly 100. When the amount of soft water in the heat dissipation assembly 100 is sufficient, the first stop valve 120 can be closed; when the amount of soft water in the heat dissipation assembly 100 is insufficient and needs to be supplemented, the first stop valve 120 can be opened, so that the soft water device 400 supplements the soft water to the heat dissipation assembly 100; when the soft water device 400 needs to be maintained, the first stop valve 120 can be closed, so that the connecting pipeline between the soft water device 400 and the heat dissipation assembly 100 is not connected, and the soft water device 400 can be maintained at this time, while the cooling device can still work in circulation and continuously produce cool air.

[0045] Further, the heat dissipation assembly 100 is provided with a water outlet 110, and the water outlet 110 is provided with a second stop valve 130. When the water in the pipeline of the cooling device accumulates a large amount of calcium, magnesium ions or other impurities, the second stop valve 130 can be opened to drain water, so as to drain the hard water or other water with high impurity content out of the cooling device, so as to avoid scale or corrosion of the pipeline.

[0046] It can be understood that in other embodiments, the display assembly 600 is also included, and the display assembly 600 is electrically connected with the monitoring assembly. The monitoring parameters of the monitoring assembly can be displayed in real time through the display assembly 600. The display assembly 600 can be arranged in other workshops or office places, and remote monitoring of the running state of the cooling system can be realized.

[0047] It can be understood that in other embodiments, the connecting pipeline between the heat dissipation assembly 100 and the refrigeration assembly 200, the connecting pipeline between the refrigeration assembly 200 and the air supply assembly 300, the connecting pipeline between the air supply assembly 300 and the second pressurizing module 310, and the connecting pipeline between the second pressurizing module 310 and the heat dissipation assembly 100 can all be provided with pressure monitoring modules, so as to monitor the water pressure in each pipeline in real time.
