Description

Technical Field

[0001] The utility model relates to the technical field of industrial processing, in particular to an energy-saving two-stage refrigeration circulation pump. Background Art

[0002] The two-stage refrigeration circulation pump plays a vital role in the refrigeration system. It goes through a two-stage compression process, that is, after the refrigerant is sucked from the evaporator, it is first compressed to the intermediate pressure by the low-pressure compressor, then cooled in the intercooler, and then compressed to the condensing pressure by the high-pressure compressor, and finally releases heat in the condenser to complete the refrigeration cycle. The design of the two-stage refrigeration circulation pump allows the refrigerant to be cooled between the two compression processes, which can reduce the exhaust temperature of the compressor and improve the refrigeration efficiency. It also helps to protect the compressor and extend its service life. In addition, the two-stage refrigeration circulation pump can also achieve different refrigeration effects, such as cooling or heating, according to different refrigeration needs by adjusting the operating status of the compressor. In general, the role of the two-stage refrigeration circulation pump is to improve the efficiency and reliability of the refrigeration system, while reducing energy consumption and maintenance costs to ensure the stable operation of the refrigeration system.

[0003] After searching, the patent number "CN212656969U" mentioned in the text that "the utility model discloses a high-efficiency and energy-saving water pressure circulation pump, which belongs to the field of circulation pumps, including a pump body and a pipeline, a joint is fixedly installed on the side of the pipeline, and the joint is slidably connected to the inner side of the pump body. Both ends of the pump body are provided with annular grooves, and the inner part of the annular groove is slidably connected with a connecting ring. The side of the connecting ring is fixedly installed with a threaded sleeve, and the threaded sleeve is threadedly sleeved on the outer side of the pipeline. The inner end side of the pump body is fixedly installed with a sealing ring, which is slidably connected to the outer side of the joint, and the lower end face of the connecting ring is fixedly installed with a sealing ring. The sealing block is slidably connected to the end face of the annular groove. When in use, the high-efficiency and energy-saving water pressure circulation pump can fix the pipeline by rotating the connecting ring so that the threaded sleeve and the outer side thread of the pipeline can be screwed together, and the installation is relatively convenient. However, when the two-stage refrigeration circulation pump is refrigerating, a large amount of heat inside the docking equipment will be brought out and dissipated by itself. However, during the heat dissipation process, due to the large power consumption of the equipment itself and long-term operation, it is easy to cause waste of resources. However, if the operation is stopped, the heat dissipation and refrigeration effect will be reduced, resulting in the problem of poor refrigeration effect.

[0004] Therefore, we provide an energy-saving two-stage refrigeration circulation pump to solve the above problems. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0025] Embodiment 1

[0026] See also Figure 1-5 As shown, the utility model provides a technical solution: an energy-saving two-stage refrigeration circulation pump, comprising a cooling tank 1 and an energy-saving cooling mechanism 2, wherein the energy-saving cooling mechanism 2 is installed inside the cooling tank 1;

[0027] The energy-saving cooling mechanism 2 comprises a water cooling component 21 and a water level positioning component 22 . The water cooling component 21 is installed on the inner side of the cooling tank 1 , and the water level positioning component 22 is installed on the right side of the water cooling component 21 .

[0028] Furthermore, the water cooling assembly 21 includes a support frame 211, an intermediate cooler 212, a liquid nitrogen pump chamber 213, a liquid nitrogen cooling nozzle 214, a bipolar circulation pump chamber 215, a water temperature sensor 216 and a multi-stage sub-control device 217. The support frame 211 is welded on the upper side of the cooling tank 1, the intermediate cooler 212 is installed in the middle of the support frame 211, the liquid nitrogen pump chamber 213 is arranged on the lower side of the intermediate cooler 212, the liquid nitrogen cooling nozzle 214 is welded on the lower side of the liquid nitrogen pump chamber 213, the bipolar circulation pump chamber 215 is arranged on the front and rear sides of the liquid nitrogen cooling nozzle 214, and the left side of the liquid nitrogen pump chamber 213 is arranged. A water temperature sensor 216 is installed, and a multi-level sub-control device 217 is installed on the upper side of the intermediate cooler 212. When it is needed, the bipolar circulation pump chamber 215 absorbs and dissipates the heat generated by the intermediate cooler 212, and the internal heat will be dissipated to the water in the cooling tank 1 through the surface of the bipolar circulation pump chamber 215, thereby achieving a water cooling effect. When the bipolar circulation pump chamber 215 operates at a high intensity, the liquid nitrogen pump chamber 213 will spray a small amount of liquid nitrogen into the water through the liquid nitrogen cooling nozzle 214, so that the liquid nitrogen is vaporized and the hot air in the water is taken away, achieving a faster cooling effect.

[0029] Furthermore, the water temperature sensor 216 is electrically connected to the liquid nitrogen pump chamber 213. The water temperature sensor 216 is an immersion type water temperature sensor. When needed, the water temperature sensor 216 will sense the water temperature in real time. When the water temperature is high, the water temperature sensor 216 will control the liquid nitrogen pump chamber 213 to work according to the water temperature conditions, thereby avoiding long-term work and causing a large amount of liquid nitrogen waste.

[0030] Furthermore, the multi-level sub-control device 217 is electrically connected to the water temperature sensor 216, and the multi-level sub-control device 217 is electrically connected to the liquid nitrogen pump warehouse 213. When needed, the multi-level sub-control device 217 will coordinate the data connection between the water temperature sensor 216 and the liquid nitrogen pump warehouse 213, and connect the data with the intermediate cooler 212 to coordinate the overall functional work.

[0031] Furthermore, the water level positioning assembly 22 includes a limit slot 221, a laser sensor 222, a telescopic rod 223, a laser generator 224 and a floating plate 225. The limit slot 221 is installed on the inner side of the cooling tank 1, the laser sensor 222 is installed in the middle of the limit slot 221, the telescopic rod 223 is installed on the inner side of the limit slot 221, the laser generator 224 is installed on the front side of the telescopic rod 223, and the floating plate 225 is installed at the end of the telescopic rod 223. When it is needed, the telescopic rod 223 is telescoped up and down along the limit slot 221. In this way, when in use, the up and down movement of the telescopic rod 223 will not occur first, and due to the influence of gravity, a relative telescopic movement with the subsequent buoyancy is generated, thereby achieving a more convenient measurement effect.

[0032] Furthermore, there is a one-to-one correspondence between the laser sensor 222 and the limit slot 221, and the laser generator 224 is electrically connected to the laser sensor 222. When it is needed, the telescopic rod 223 drives the laser generator 224 to pass through the laser sensor 222, and the laser sensor 222 will sense the laser scan. When it reaches the middle position of the laser sensor 222, it will issue a warning or control the subsequent water inlet component 3 to perform a water replenishment operation.

[0033] Furthermore, the floating board 225 and the telescopic rod 223 are adhesively connected. The floating board 225 is made of hollow plastic. When needed, the floating board 225 will float on the water surface, thereby lifting the telescopic rod 223 upward. Through the cooperation of gravity, the floating board 225 can always sense the water surface height.

[0034] Embodiment 2

[0035] See also Figure 1 and Figure 2 As shown, compared with Example 1, as another implementation of the utility model, a water inlet component 3 is installed on the front side of the cooling tank 1, and the water inlet component 3 includes a water inlet pump 31 and an intelligent controller 32. The water inlet pump 31 is welded on the front side of the cooling tank 1, and the intelligent controller 32 is installed on the upper side of the water inlet pump 31. When it is needed, as the laser sensor 222 senses that the water level is lowered, the intelligent controller 32 will control the water inlet pump 31 to inject water into the cooling tank 1, so as to ensure that the water in the cooling tank 1 can completely sink the bipolar circulation pump chamber 215.

[0036] Working principle: an energy-saving two-stage refrigeration circulation pump is moved to the working position. When in use, the first step is to place the cooling tank 1 in the position where it needs to be used, and then the water is discharged into the cooling tank 1 through the water inlet pump 31. The second step is that the intermediate cooler 212 in the support frame 211 is cooled by the bipolar circulation pump chamber 215 for refrigeration circulation. When the operation intensity is large and the water temperature sensor 216 senses the increase in water temperature, the multi-stage sub-control device 217 will control the liquid nitrogen pump chamber 213 to spray liquid nitrogen into the water along the liquid nitrogen cooling nozzle 214 submerged in the water. The third step is that during the water-cooled evaporation process, the telescopic rod 223 in the limit card slot 221 will sense the water level through the floating plate 225. When the water level drops, the laser generator 224 on the telescopic rod 223 will pass through the position of the laser sensor 222, thereby controlling the water inlet pump 31 to inject water into the cooling tank 1 through the intelligent controller 32, thus completing the use process of an energy-saving two-stage refrigeration circulation pump.
