DETAILED DESCRIPTION

[0017] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0018] Please refer to Figs. 1-4 In the embodiments of the present application, the salt water cooling automatic control device comprises a water tank assembly 1 composed of a salt water tank 101, a water supplement pipe 102 and a water outlet pipe 103, and further comprises a cooling assembly 2. The water supplement pipe 102 is connected to the top of one side of the water outlet pipe 103. The water outlet pipe 103 is fixed to the bottom of one end of the salt water tank 101. The water supplement pipe 102 and the water outlet pipe 103 are in communication with the inner side of the salt water tank 101. The cooling assembly 2 is distributed on the side, top and inner side of the salt water tank 101. The cooling assembly 2 is used for cooling the salt water in the salt water tank 101. The salt water tank 101 is fixed with a plurality of flow resistance partitions 104 on the inner side. The plurality of flow resistance partitions 104 are evenly distributed along the vertical direction. A plurality of water permeable holes 105 are formed in the top of each flow resistance partition 104 and penetrate through to the bottom of the flow resistance partition 104. The plurality of water permeable holes 105 are distributed in a matrix. The distribution positions of the water permeable holes 105 on the adjacent two flow resistance partitions 104 are in a staggered state.

[0019] When the salt water in the salt water tank 101 is supplemented through the water supplement pipe 102, the plurality of flow resistance partitions 104 buffer the flowing speed of the entering salt water downward, so as to reduce the mixing and heat exchange efficiency of the newly entering salt water and the salt water at the bottom of the salt water tank 101.

[0020] A liquid level meter 4 is installed on the side of the salt water tank 101. The upper end of the liquid level meter 4 and the water inlet of the water supplement pipe 102 are distributed above the uppermost flow resistance partition 104.

[0021] The horizontal height of the lowermost flow resistance partition 104 is higher than the port of the water outlet pipe 103 and the horizontal height of the lower port of the flow resistance partition 104.

[0022] A temperature sensor 3 is installed on the end of the salt water tank 101 away from the water outlet pipe 103. The temperature sensor 3 is inserted into the salt water tank 101 in an inclined downward state.

[0023] The length of the flow resistance partition 104 corresponding to the installation track of the temperature sensor 3 decreases in turn. The flow resistance partition 104 with decreasing length in turn is fixed with an inclined plugging plate 106 on the end close to the temperature sensor 3.

[0024] The cooling assembly 2 comprises a water inlet pipe 201, an electromagnetic valve 202, a heat exchange coil 203 and a backflow pipe 204.

[0025] The water inlet pipe 201 is fixed to one side outside the saltwater tank 101, and one end of the water inlet pipe 201 is communicated with the external refrigerated saltwater conveying pipe through the electromagnetic valve 202.

[0026] The heat exchange coil 203 is distributed inside the saltwater tank 101 and connected to the water inlet pipe 201 at one end, and the other end of the heat exchange coil 203 extends to the upper end of the saltwater tank 101 and is connected to the return pipe 204.

[0027] In this embodiment, it needs to be noted that the water outlet pipe is connected to the storage tank and condenser that need to be cooled through the water pump, and the temperature sensor 3 and the liquid level gauge 4 are electrically connected to the external controller, and the working principle is as follows:

[0028] The temperature of the saltwater in the saltwater tank 101 is measured in real time by the temperature sensor 3, and the control instrument controls the electromagnetic valve 202 to open according to the measured temperature when the saltwater tank 101 rises to the set maximum temperature, and the external refrigerated saltwater enters the heat exchange coil 203 through the water inlet pipe 201 to cool the saltwater in the saltwater tank 101, and the refrigerated saltwater after heat exchange flows out through the return pipe 204. When the temperature of the saltwater in the saltwater tank 101 drops to the required low temperature, the electromagnetic valve 202 is closed to stop cooling. When the temperature of the saltwater in the saltwater tank 101 reaches the required temperature, the external water pump can be started to deliver the saltwater to the storage tank and condenser that need to be cooled. In this process, the liquid level of the saltwater tank 101 is monitored in real time by the liquid level gauge and transmitted to the external controller. When the liquid level of the saltwater tank 101 is lower than the set minimum water level, the external pipeline supplements the saltwater in the saltwater tank 101 through the water supplement pipe 102. When the liquid level is higher than the set maximum water level, the saltwater supplement is stopped.

[0029] In the process of supplementing the saltwater, the temperature of the supplemented saltwater is higher than that of the saltwater in the saltwater tank 101, and if they are directly contacted, they will exchange heat and cause the temperature of the saltwater in the saltwater tank 101 to rise, so that the single drainage amount is reduced. The structure of the plurality of flow resistance partitions 104 allows the supplemented saltwater to flow downward through the water permeable holes 105 step by step, which can effectively reduce the downward flow speed of the supplemented saltwater, so that the impact force is small when the supplemented saltwater contacts the saltwater in the saltwater tank 101, thereby reducing the mixing and heat exchange between them, so that the temperature of the saltwater at the bottom of the saltwater tank 101 remains stable for a longer time, thereby increasing the amount of saltwater that can be drained at a time.

[0030] When the original saltwater in the saltwater tank 101 is drained a lot, the temperature of the saltwater in the saltwater tank 101 will rise, and the external water pump can be stopped and the electromagnetic valve 202 can be started for secondary cooling operation, so that the refrigerated saltwater can be circulated stably.

[0031] Please refer to Figs. 1-4The flow resistance partition plate 104 and the inclined blocking plate 106 are further provided with mounting holes 107 for the heat exchange coil 203 to be installed through, and the distribution area of the heat exchange coil 203 does not interfere with the mounting area of the temperature sensor 3.

[0032] In the embodiment, the direct contact of the incoming supplementary brine with the temperature sensor 3 is avoided by the arrangement of the inclined blocking plate 106, so that the temperature monitoring deviation is avoided, and the heat exchange coil 203 does not affect the dismounting operation of the temperature sensor 3.

[0033] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
