Description

Technical Field

[0001] The utility model relates to the technical field of water supply for refrigeration stations, in particular to a cooling water balance device for refrigeration stations. Background Art

[0002] The cooling water balance device of the refrigeration station is a device used to adjust and control the amount of water in the cooling water system of the refrigeration station to ensure the normal operation of the system. It is often arranged in the factory area to extract water from the water pool and then transport it to the factory building after refrigeration treatment. It cools down some equipment or parts that need water cooling during the processing in the factory building. The cooled water is sent from the factory building to the water pool through pipes to realize the recycling of water resources;

[0003] In the process of cooling the equipment or parts in the factory, the existing cold east station usually evaporates a lot of water, resulting in the amount of water output from the factory to the pool each time being lower than the amount of water input from the pool to the factory. For this reason, it is necessary to frequently use tap water to replenish the water volume in the pool so that the water volume in the pool is at a normal water level. As a result, the existing cooling water supply pool is prone to overflow during periods of abundant rain, and the water storage effect is poor, resulting in a waste of low-temperature water sources. In daily use, it is necessary to regularly observe the water level line of the water supply pool to determine whether additional tap water is needed to be added to the pool. It is easy for the tap water in the water supply pool to be untimely replenished, resulting in a serious water shortage in the supply pool, affecting the cooling of the running equipment and causing the equipment to overheat and be damaged.

[0004] The above contents are only used to assist in understanding the technical solution of the present utility model, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

[0034] 3. The utility model sets an expansion groove in the second water supply tank to ensure that the water in the second water supply tank at a height corresponding to the first through groove is directly introduced into the first water supply tank through the first through groove, thereby reducing the need to pump water in the second water supply tank into the first water supply tank through the second water pump, thereby saving energy consumption.

[0063] Furthermore, the water storage unit 2 also includes:

[0064] A reserved groove 212 is provided at one side of the bottom of the second water supply tank 21, and the reserved groove 212 is located below the second through groove 116;

[0065] The second water pump 23 is arranged in the reserved groove 212. The upper end of the second water pump 23 is connected to the third input pipe 24. The outlet of the third input pipe 24 is located inside the first water supply tank 111. It is used to pump water in the second water supply tank 21 into the first water supply tank 111 when the water level in the first water supply tank 111 is lower than the lower water level line 112.

[0066] Furthermore, an expansion groove 211 is provided inside the second water supply tank 21, and the width of the expansion groove 211 is greater than the width of the second water supply tank 21, the upper end of the expansion groove 211 is higher than the upper end of the first through groove 115, and the lower end of the expansion groove 211 is at the same height as the lower end of the first through groove 115, which is used to increase the amount of water supplied from the first through groove 115 by the second water supply tank 21 to the first water supply tank 111.

[0067] As an improvement, the water storage unit 2 further includes:

[0068] A water retaining frame 25 is connected to the upper end of the second water supply tank 21;

[0069] The inclined plate 26 is inserted into the upper end of the water retaining frame 25. The upper end of the inclined plate 26 is an inclined surface, which is used to guide the rainwater falling on the inclined plate 26 into the second water supply tank 21 for storage;

[0070] A transition plate 28 connected to the inside of the water retaining frame 25 and located at the inclined bottom of the inclined plate 26;

[0071] The baffle plate 27 is slidably inserted in the water retaining frame 25 and is used to cooperate with the transition plate 28 to seal the water in the second water supply tank 21 .

[0072] The upper end of the first water supply tank 111 is also provided with a water retaining frame 25 at the same height as the upper end of the second water supply tank 21.

[0073] Furthermore, a drain port 22 is provided on one side of the water retaining frame 25 . The drain port 22 is provided on one side of the water retaining frame 25 . The drain port 22 is located between the second through groove 116 and the transition plate 28 , and is used to discharge water that is about to overflow from the second water supply tank 21 .

[0074] It should be added that the volume of the second water supply tank 21 in the utility model is larger than that of the first water supply tank 111. The first water supply tank 111 and the second water supply tank 21 are arranged separately on the stratum 100 instead of being directly combined. On the one hand, this is to target the actual distribution of some factory buildings 101 in the factory area, and the first water supply tank 111 cannot be built too large, which will affect the reasonable layout of the factory area. On the other hand, by arranging the first water supply tank 111 and the second water supply tank 21 separately, it is convenient to regularly clean up the impurities at the bottom of the first water supply tank 111 and the second water supply tank 21 separately. Among them, the first water supply tank 111 is used to directly supply water to the factory building 101 and recycle it. Therefore, the amount of impurities precipitated per unit time in the first water supply tank 111 is greater than the amount of sediment in the second water supply tank 21, and the required cleaning cycle is shorter.

[0075] It should also be added that the water level in the first water supply tank 111 in the utility model is the same height as the upper water level line 114 as the highest water level line, the same height as the middle water level line 113 as the standard water level line, and the same height as the lower water level line 112 as the lowest water level line. The buoyancy ball 124 in the utility model can be a hollow plastic sphere.

[0076] It should be noted that: in the specific implementation process of the present invention, the first water pump 1023 pumps the water in the first water supply tank 111 into the refrigeration unit 102 through the second input pipe 1022 for cooling, and the refrigeration unit 102 inputs the cooled water into the factory building 101 through the first input pipe 1021 for cooling the equipment or processed parts in the factory building 101. The water in the factory building 101 after cooling is discharged into the first water supply tank 111 through the output pipe 1011 for recycling;

[0077] Since a certain amount of cooling water is evaporated each time it is input into the plant 101 through the first input pipe 1021 during the process of cooling down the equipment or parts, the amount of water input into the first water supply tank 111 through the output pipe 1011 is less than the amount of water input into the plant 101 through the first input pipe 1021, and thus the amount of water in the first water supply tank 111 gradually decreases;

[0078] To this end, when the water level in the first water supply tank 111 of the utility model is between the middle water level line 113 and the upper water level line 114, the buoyancy ball 124 pulls the valve block 122 upward through the lifting rod 123 under the upward buoyancy of the water in the first water supply tank 111, so that the first through groove 115 is blocked by the valve block 122. As the water level of the first water supply tank 111 gradually decreases during use, the buoyancy ball 124 also gradually decreases with the height of the water level. When the water level in the first water supply tank 111 is lower than the middle water level line 113 and gradually decreases, the height of the buoyancy ball 124 is lower than the middle water level line 113 and gradually decreases with the water level. At this time, under the action of the gravity of the valve block 122 itself, the valve block 122 gradually moves downward along the water outlet frame 121, so that the water outlet frame 121 is initially opened, and the water in the second water supply pool 21 enters the first water supply pool 111 through the first through groove 115 and the water outlet frame 121 in turn, so that the first water supply pool 111 can supply water in time, thereby achieving the goal of being able to automatically supply water to the first water supply pool 111 after the water level of the first water supply pool 111 drops below the standard water level, without the need for manual regular water supply to the first water supply pool 111, thereby avoiding the situation where the first water supply pool 111 is seriously short of water due to untimely water supply;

[0079] When the water level in the first water supply tank 111 is lower than the lowest water level corresponding to the lower water level line 112, at this time, the valve block 122 fully opens the water outlet frame 121, after which the second water supply tank 21 cannot supply water to the first water supply tank 111 through the first through groove 115. At this time, the second pump 23 can be turned on, and the second pump 23 pumps the water in the second water supply tank 21 into the first water supply tank 111 through the third input pipe 24, so that the water level in the first water supply tank 21 is maintained at the lowest water level. At the same time, tap water is input into the first water supply tank 111 to maintain the water level in the first water supply tank 111, so as to avoid untimely water supply due to the second water supply tank 21 being completely drained before supplying water to the first water supply tank 111;

[0080] The utility model sets an expansion groove 211 in the second water supply tank 21 to ensure that the water in the second water supply tank 21 corresponding to the height of the first through groove 115 is directly introduced into the first water supply tank 111 through the first through groove 115, thereby reducing the need to pump water in the second water supply tank 21 into the first water supply tank 111 through the second water pump 23, thereby saving energy consumption.

[0081] It should also be noted that, during the implementation of the present invention, the baffle 27 cooperates with the transition plate 28 and the inclined plate 26 to close the second water supply pool 21, thereby preventing the water source in the second water supply pool 21 from being precipitated by impurities, while the upper end of the first water supply pool 111 with a shorter cleaning cycle is in an open state. During rainfall, the baffle 27 is pulled along the water retaining frame 25 to separate the baffle 27 from the transition plate 28, and rainwater falls into the first water supply pool 111 and the second water supply pool 21 respectively. When the water level in the first water supply pool 111 reaches the second through groove 116, the rainwater that subsequently falls into the first water supply pool 111 is discharged into the second water supply pool 21 through the second through groove 116. When the water level in the second water supply pool 21 reaches the drain port 22, the water that subsequently falls into the second water supply pool 21 is discharged at the drain port 22, thereby achieving the effect of automatically storing rainwater and saving a large amount of water resources.

[0082] Since the opening of the second water supply tank 21 is relatively large and difficult to open or close, the utility model provides an inclined plate 26 in the upper water retaining frame 25 of the second water supply tank 21. Rainwater falling into the second water supply tank 21 is first guided to the transition plate 28 through the inclined plate 26 in the water retaining frame 25, and then introduced into the gap between the baffle plate 27 and the transition plate 28 through the transition plate 28 to enter the second water supply tank 111 for storage. The storage of rainwater in the second water supply tank 21 can be controlled by adjusting the baffle plate 27, which is convenient and quick.
