Description

Technical Field

[0001] This utility model relates to a heat pump unit with automatic cleaning and sewage discharge, belonging to the technical field of aquaculture equipment. Background Technology

[0002] Based on years of experience among sea cucumber farmers, the optimal water temperature for sea cucumber farming is between 14℃ and 19℃, with 16℃ being the most suitable. Below 14℃, sea cucumbers grow too slowly, while above 20℃, bacteria easily proliferate in the farming ponds. At 16℃, sea cucumbers typically double their weight in about a month, while below 14℃, the growth rate is slower, taking two or even three months. More importantly, the size of the sea cucumbers sold in the current season may not meet market demand. Furthermore, excessively high water temperatures in summer can easily lead to disease and even entire ponds dying, which is also detrimental to sea cucumber farming. Deep-well seawater has a temperature of around 16℃. In winter, after being transported through a 5-kilometer pipeline, the water temperature drops to below 11℃-13℃, while in summer it rises to 20℃-22℃. Therefore, winter water temperatures are unfavorable for sea cucumber growth, and summer water temperatures easily cause disease. To maintain the water temperature within a specified range, a water source heat pump can be added to transfer heat from the deep well to the aquaculture pond. However, deep wells contain a lot of impurities, so the water source heat pump needs to be cleaned regularly; otherwise, blockages will affect its working efficiency. Utility Model Content

[0022] The working principle of one embodiment of this utility model is as follows: Water from the deep well 2 enters the heat exchanger 4 under the action of the first pump body 3. In the heat exchanger 4, the heat from the water is transferred to the medium in the first circulating medium pipeline 6. Because of the heat exchanger 4, the water from the deep well 2 is prevented from directly entering the evaporator 7, thus avoiding blockage of the evaporator 7. Under the action of the evaporator 7, the third pump body 14, and the expansion valve 13, the temperature of the medium in the second circulating medium pipeline 8 is increased, and this temperature is transferred to the medium in the third circulating medium pipeline 11, thereby raising the temperature of the water in the aquaculture pond 10.

[0023] Solar panels 5 are installed on the roof area of ​​the greenhouse, employing a photovoltaic direct-drive heat pump. The evaporator 7 is coated with graphene material, reducing heat transfer efficiency by less than 5% while increasing the heat exchange area by 5%. The condenser uses a corrosion-resistant copper alloy with high thermal conductivity. Corrosion protection measures such as sacrificial anodes and electron anodes are used inside the heat exchanger.

[0024] Water from the deep well 2 enters the outer casing 17 through the inlet tank 21, directly contacting the heat-conducting pipe 26, and then exits through the outlet tank 19. Both the inlet tank 21 and the outlet tank 19 are located below the casing 17, providing some turbulence and preventing impurities from accumulating inside the casing 17. Furthermore, the water flow acts on the guide plate 22, pushing the inner ring 25 to rotate under tangential force. During rotation, the water flow forms a vortex under the action of the guide plate 22, acting on the heat-conducting pipe 26 and washing away impurities deposited on it, which then fall into the collection box 20. The outer ring 23, inner ring 25, sealing ring 24, and balls of the bearing structure can all be made of high-molecular-weight plastic materials to prevent corrosion by seawater.
