specific Embodiment approach 1

[0006] Specific embodiment one: (referring to Fig. 1, Fig. 2) this embodiment consists of a water intake pipe 1, a cold water pump 2, a heat exchange freezer 3, a sealing ring 4, a chain 5, a main shaft 6, a motor reducer 7, and a drain pipe 8 , circulating pump 9, circulating water outlet pipe 10, circulating water inlet pipe 11, heat exchange freezing pipe 12, auger scraper 13, cold water inlet mask 14 and ice floc outlet mask 15; cold water inlet mask 14 and ice floc outlet mask 15 respectively fixed on the two ends of the heat exchange freezer 3, the outlet end of the water intake pipe 1 communicates with the cold water inlet mouthpiece 14, the inlet end of the water intake pipe 1 communicates with the outlet end of the cold water pump 2, and the inlet end of the cold water pump 2 It is connected with the water source, the inlet end of the drain pipe 8 is connected with the ice floc outlet mouthpiece 15, the outlet end of the drain pipe 8 is connected with the water source,...

specific Embodiment approach 2

[0007] Embodiment 2: (see FIG. 1 and FIG. 2 ) The inner diameter of the heat exchange and freezing tube 12 of this embodiment is 60-100 mm. The length of the heat exchange and freezing pipe 12 is 5-8m. The number of roots is determined by the required heat exchange and freezing area. Many heat exchange freezing tubes 12 are arranged in several rows in parallel, 5-8 in every row. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0008] Specific embodiment three: (see Fig. 1, Fig. 2) the oblique angle γ of the auger scraper 13 of this embodiment deviates from the axial direction by 20 degrees, and the outer diameter of the auger scraper 13 is smaller than the inner diameter of the heat exchange and freezing tube 12 0.5-1mm. Other compositions and connections are the same as in the first embodiment. Through the slow rotation (1 revolution per minute) of the auger scraper 13, the ice formed on the inner wall of the heat exchange and freezing tube is scraped and cut off, and flows away with the water, so as to ensure the non-blocking operation of the subsequent pipeline.

Abstract

The invention relates to a collector of cold water solidification heat. The heat exchange icing pipe (12) is fixed inside the heat exchange icing device (3) while they are sealing connected by the sealing ring (4) to form a water-glycol space (16); the heat exchange icing pipe (12) has a water-ice space (17); the continuous scrapping plate (13) is arranged inside the heat exchange icing pipe (12) while its one end is connected to the main axle (6) on the end of heat exchange icing pipe (12); and the main axle (6) is connection to the motor speed reducer (7) inside the cold water inlet cover (14) via the chain transmission. The invention has simple structure and high heat-collection efficiency, while it can break the point of 0Deg. C to ice the water and attain the solidification heat.

Description

technical field [0001] The invention relates to a device for collecting solidification heat from cold water. Background technique [0002] Using water source heat pump technology to extract heat from water in the environment for heating and air conditioning of buildings can increase the utilization rate of electric energy to four times. It not only utilizes renewable energy, but also avoids the inevitable pollution of the environment by using fossil fuels as heat sources. Heat pump heating technology has appeared for nearly a hundred years, and it has long been recognized as an excellent technology that is both energy-saving and environmentally friendly. However, heat pump technology has not been widely promoted. The reason is that the water in the environment suitable for heat pump water source is not everywhere. In fact, the lack of suitable water source is the bottleneck of the popularization and application of heat pump technology. The heat pump water sources that peop...
