Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0022] The air compressor system in the production workshop uses softened water for cooling, and a closed-loop cooling tower provides cooling water to the internal circulation system of the air compressor. When the ambient temperature of the air compressor is too high and the cooling water in the closed-loop cooling tower is insufficient to achieve the desired cooling effect, the cooling water inside the closed-loop cooling tower will be discharged externally, and then replenished with new softened water. When the discharge flow rate is too large, it leads to a severe shortage of water supply from the softening water equipment. When the inflow is less than the outflow, it can easily cause the air compressor to shut down abnormally due to high temperature, thus affecting the production line and causing significant production losses.

[0023] To address the aforementioned technical problems, this application provides a circulating water cooling device that can recycle the cooling water flowing out of the closed cooling tower, thereby avoiding insufficient water supply and abnormal shutdown of the air compressor due to high temperature. This is beneficial for the stable operation of production equipment and reduces losses caused by downtime.

[0024] The following is in conjunction with the instruction manual. Figures 1-3 A detailed explanation will be provided.

[0025] This application provides a circulating water cooling device, such as... Figure 1 As shown, the circulating water cooling device includes: a cooling tower 1, which is connected to the inlet and outlet of the cooling circulation system of the air compressor 3; a water treatment component 2, including an inlet pipe 21, a water treatment component 22, and an outlet pipe 23, wherein the inlet pipe 21 is connected to the water treatment component 22 and the cooling tower 1, and the outlet pipe 23 is connected to the water treatment component 22 and the cooling tower 1; a liquid level control component, including a liquid level monitoring component, a controller, and an on / off switch 7, wherein the on / off switch 7 is located in the inlet pipe 21, the liquid level monitoring component is located inside the water treatment component 22, and the controller is electrically connected to the on / off switch 7 and the liquid level monitoring component; and a liquid replenishment component 4, which is connected to the inlet pipe 21.

[0026] Specifically, such as Figure 1As shown, the circulating water cooling device includes a cooling tower 1, a water treatment component 2, a liquid level control component, and a liquid replenishment component 4. The cooling tower 1 is connected to the inlet and outlet of the cooling circulation system of the air compressor 3. The cooling tower 1 is used to cool the water entering its interior and then transport the cooled water to the cooling circulation system of the air compressor 3 to cool the air compressor. It also recovers the water output from the cooling circulation system of the air compressor 3, thus recycling the cooling water, saving energy and reducing emissions. The water treatment component 2 includes an inlet pipe 21, a water treatment component 22, and an outlet pipe 23. The inlet pipe 21 is connected to the inlet of the water treatment component 22 and the outlet of the cooling tower 1. The outlet pipe 23 is connected to the outlet of the water treatment component 22. The water inlet and cooling tower 1 are connected by a water treatment component 22, which filters the cooling water and further cools it. The liquid level control component includes a liquid level monitoring component, a controller, and an on / off switch 7. The controller is electrically connected to the on / off switch 7 and the liquid level monitoring component. The on / off switch 7 is located in the water inlet pipe 21. The liquid level monitoring component is located in the water treatment component 22 and is used to monitor the water level inside the water treatment component 22. When the water level reaches a certain value, the liquid level monitoring component will send a liquid level signal to the controller. The controller processes the liquid level signal and sends a close or open signal to the on / off switch 7. The liquid replenishment component 4 is connected to the water inlet pipe 21 and is used to replenish water to the cooling tower 1.

[0027] like Figure 3 As shown, one air compressor 3 requires one circulating water cooling device. When there are multiple air compressors 3, multiple circulating water cooling devices are needed. When multiple circulating water cooling devices supply multiple air compressors 3, the structure of the inlet pipe 21 and the outlet pipe 23 needs to be changed. Optionally, the inlet pipe 21 has multiple inlet ends, one of which corresponds to the drain end of a cooling tower 1. The inlet pipe 21 also has multiple outlet ends, one of which corresponds to the inlet end of a water treatment component 22. Similarly, the outlet pipe 23 has multiple inlet ends, one of which corresponds to the outlet end of a water treatment component 22. Finally, the outlet pipe 23 has multiple outlet ends, one of which corresponds to the inlet end of a cooling tower 1.

[0028] Furthermore, the cooling tower 1 is a closed cooling tower. The cooling tower 1 has a top and a bottom. The top of the cooling tower 1 has a water inlet end, a water return end, a water outlet end and a water drain end. The water inlet end and the water return end are located at the top of the cooling tower 1, and the water outlet end and the water drain end are located at the bottom of the cooling tower 1.

[0029] In some optional embodiments, the circulating water cooling device further includes a first conveying pipe 5, which is connected to the inlet end of the cooling circulation system of the air compressor 3 and the outlet end of the cooling tower 1, respectively.

[0030] Specifically, the cooling tower 1 is used to cool the water entering its interior. The first conveying pipe 5 is connected to the inlet end of the cooling circulation system of the air compressor 3 and the outlet end of the cooling tower 1, thereby conveying the cooling water in the cooling tower 1 to the cooling circulation system of the air compressor 3 to cool the air cooler.

[0031] In some optional embodiments, the circulating water cooling device further includes a second conveying pipe 6, which is connected to the outlet end of the cooling circulation system of the air compressor 3 and the return water end of the cooling tower 1, respectively.

[0032] Specifically, after the cooling water circulates in the air compressor 3, it flows out and the temperature of the cooling water rises. The second conveying pipe 6 is connected to the outlet end of the cooling circulation system of the air compressor 3 and the return water end of the cooling tower 1, respectively, so as to recycle the heated cooling water back into the cooling tower 1 and recover the coolant flowing out of the cooling circulation system of the air compressor 3, thereby recycling the cooling water, saving energy and reducing emissions.

[0033] In some alternative embodiments, the water treatment component 22 is a soft water tank.

[0034] Specifically, the function of a water softener is to soften water and remove impurities. Water softeners use ion exchange technology to remove hard water components such as calcium and magnesium, converting them into sodium ions, thus making the water softer. This process not only improves water quality but also reduces scale formation. The filter cartridge in the water softener effectively filters out impurities such as sediment, rust, and organic matter, improving water clarity and transparency. Furthermore, the water softener's excellent corrosion resistance and sealing performance prevent dissolved oxygen and impurities from entering the tank, maintaining water purity.

[0035] In some optional embodiments, the water treatment component 22 includes a tank 221 and a filter component, the filter component being disposed inside the tank 221, the inlet pipe 21 being connected to the tank 221 and the cooling tower 1 respectively, and the outlet pipe 23 being connected to the tank 211 and the cooling tower 1 respectively.

[0036] Specifically, the inlet pipe 21 connects the drain end of the cooling tower 1 to the inlet end of the tank 221, and the outlet pipe 23 connects the outlet end of the tank 221 to the inlet end of the cooling tower 1. The cooling tower 1 is used to cool the water entering its interior. When the ambient temperature of the air compressor 3 is too high and the cooling water in the closed-loop cooling tower 1 cannot achieve the cooling effect, the cooling water inside the closed-loop cooling tower 1 will be discharged to the outside. The closed-loop cooling tower 1 enters the tank 221 through the inlet pipe 21. The filter component can not only filter the cooling water, but also further cool it. Afterwards, it flows back into the cooling tower 1 through the inlet pipe 21. The cooling tower 1 is used to cool the water entering its interior and delivers the cooled water to the cooling circulation system of the air compressor 3, thereby cooling the air compressor and realizing the recycling of cooling water, saving energy and reducing emissions.

[0037] In some alternative embodiments, such as Figure 3 As shown, the filter components include a primary filter element 222, a secondary filter element 223, and a tertiary filter element 224, which are arranged sequentially from top to bottom inside the tank 221.

[0038] Specifically, the cooling tower 1 enters the tank 221 through the inlet pipe 21, and flows out from the outlet end of the tank 221 after passing through the primary filter element 222, the secondary filter element 223 and the tertiary filter element 224 in sequence. The primary filter element 222, the secondary filter element 223 and the tertiary filter element 224 filter the cooling water in sequence, which not only makes the cooling water of better quality, but also further cools the cooling water and can supply water to the cooling tower 1 as quickly as possible.

[0039] Furthermore, the primary filter element 222, the secondary filter element 223, and the tertiary filter element 224 are arranged sequentially from top to bottom inside the tank 221, realizing graded filtration. The graded filtration of cooling water can effectively filter out impurities and contaminants in the cooling water, preventing these impurities from damaging the air compressor 3 during the production process, reducing the number of times the air compressor 3 is damaged or malfunctions, thereby reducing the maintenance cost of the equipment.

[0040] In some optional embodiments, the primary filter element 222 is a primary filter plate with a plurality of first filter holes, and the secondary filter element 223 is a secondary filter plate with a plurality of second filter holes, wherein the diameter of the first filter holes is larger than the diameter of the second filter holes.

[0041] Specifically, the primary filter plate has multiple first filter holes, and the secondary filter plate has multiple second filter holes. The diameter of the first filter holes is larger than the diameter of the second filter holes, thereby refining and screening the impurities. Some impurities are screened out from the primary filter plate, and some impurities are screened out from the secondary filter plate.

[0042] Furthermore, the tank body 221 is internally provided with a first limiting ring and a second limiting ring. The outer periphery of the first limiting ring is welded to the inner surface of the tank body 221, and the outer periphery of the second limiting ring is welded to the inner surface of the tank body 221. The first limiting ring is located near the top of the tank body 221, and the second limiting ring is located near the bottom of the tank body 221. The first limiting ring supports the primary filter element 222, and the second limiting ring supports the secondary filter element 223.

[0043] In some alternative embodiments, the tertiary filter element 224 includes a resin layer 225, a quartz sand layer 226, a manganese sand layer 227, and an activated carbon layer 228 stacked together.

[0044] Specifically, resin layer 225 removes calcium and magnesium ions from the water using ion exchange technology. These ions are the main causes of water hardness and scale. Resin layer 225 adsorbs calcium and magnesium ions in the water and releases sodium ions, thereby reducing water hardness and making the water purer. Quartz sand layer 226 removes suspended solids, organic matter, colloidal particles, silt, and other impurities from the water, reducing turbidity and improving clarity. Manganese sand layer 227 effectively removes suspended solids, turbidity, colloids, and other impurities from the water, significantly improving water transparency and clarity. Manganese sand, through oxidation-reduction reactions, oxidizes dissolved iron and manganese ions in the water into insoluble hydroxides or oxides, and captures and removes these substances through its surface micropores, thereby reducing the iron and manganese content in the water. Activated carbon layer 228 adsorbs impurities, odors, pigments, and heavy metal ions from the water. Activated carbon has a loose and porous structure with a large surface area, enabling it to adsorb organic pollutants, chlorine, and heavy metal ions from the water.

[0045] In some optional embodiments, the liquid replenishment component 4 includes a water storage tank 41, a water pump 42, and a water delivery pipe 43. The water delivery pipe 43 is connected to the water storage tank 41 and the water inlet pipe 21, respectively, and the water pump 42 is disposed on the water delivery pipe 43.

[0046] Specifically, the water storage tank 41 stores soft water. When the cooling tower 1 is short of water, the water pump 42 starts working, and the soft water in the water storage tank 41 enters the cooling tower 1 through the water delivery pipe 43, thereby quickly replenishing the water in the cooling tower 1.

[0047] In some alternative embodiments, the level monitoring component is a float level gauge, and the on / off switch 7 is a solenoid valve.

[0048] Specifically, the controller is electrically connected to the solenoid valve and the float level gauge respectively. The solenoid valve is installed in the water inlet pipe 21, and the float level gauge is installed inside the water treatment unit 22 to monitor the water level inside the water treatment unit 22. When the water level reaches a certain value, the float level gauge will send a level signal to the controller. The controller processes the level signal and sends a close or open signal to the solenoid valve so that the water level inside the water treatment unit 22 is always in a reasonable state.
