Description

Technical Field

[0001] This invention relates to the field of condensers, and in particular to a low-temperature condenser for a well water machine room in a livestock farm. Background Technology

[0002] A well source heat pump chiller / hot water unit room is a core equipment room of a central air conditioning system that uses groundwater (usually extracted and reinjected from wells) as a heat source to provide cooling in summer, heating in winter, and domestic hot water for buildings. In summer, it transfers heat from the building to the groundwater, cools it, and then reinjects it. In winter, it extracts heat from the groundwater and uses it for heating.

[0003] Groundwater has a higher impurity content than pure water, which can easily cause scale, algae blooms and other foreign matter to form on the surface of pipes and condensers, affecting the heat exchange efficiency of the condenser. The condenser is a closed structure and is equipped with heat exchange tubes, making it inconvenient to disassemble, assemble and clean. The purpose of this invention is to propose a new condenser structure to solve the above-mentioned technical problems and facilitate the cleaning of foreign matter attached to the condenser. Summary of the Invention

[0004] The purpose of this invention is to provide a low-temperature condenser for well water in aquaculture farms to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: comprising a shell, a rotating ring, and a cavity. Heat medium channels are provided at both ends of the shell, and these channels are connected to external pipes that provide the heat medium. A support ring is fixedly installed inside the shell, and a through hole is formed on the support ring. A connecting rod is provided along the length of the shell at the through hole, and an annular scraper is provided at the end of the connecting rod. The annular scraper is inserted into the inner wall of the heat exchange tube via the connecting rod. During the movement of the heat exchange tube, the annular scraper can scrape off foreign matter adhering to the inner wall of the heat exchange tube. Waste discharge holes are provided on both sides of the shell, and the foreign matter separated during the cleaning process can be discharged from the waste discharge pipe after separating from the interface.

[0006] The rotating ring is rotatable within the housing via a bearing ring. The rotating rings are arranged side by side along the length of the housing. A movable magnetic ring is fitted on the outside of the housing, and the movable magnetic ring attracts the rotating ring. The movable magnetic ring and the housing form a cylindrical pair. Here, the movable magnetic ring refers to a magnetic ring that can move freely. A roller is embedded inside the rotating ring, forming a cylindrical pair with the rotating ring. A polytetrafluoroethylene (PTFE) film is provided inside the housing to cover the surface of the rotating ring. PTFE has excellent chemical corrosion resistance, high temperature resistance, and an extremely low surface friction coefficient. Its purpose is to reduce the adhesion of foreign matter. During the rotation of the rotating ring, the roller can resist the PTFE film, causing the surface of the PTFE film to undulate, thereby separating the foreign matter attached to the surface of the PTFE film.

[0007] The cavity has a refrigerant channel on its side, which is connected to an external pipe that provides the refrigerant. The cavity also includes a contact plate and a sealing plate. The contact plate abuts against the shell surface and covers the exhaust hole to prevent refrigerant leakage at the exhaust hole when the condenser is working. A heat exchange tube is formed on the contact plate, which penetrates the shell and forms a sliding pair along the length of the shell. The end of the heat exchange tube abuts against the support ring and cooperates with the through hole. The heat exchange tube surrounds the connecting rod and the annular scraper abuts against the inner wall of the heat exchange tube. The sealing plate is connected to the contact plate through a connecting column. The sealing plate and the contact plate form an opening that matches the shape of the heat medium channel. In a specific implementation, the sealing plate can be detachably connected to the cavity by bolts. In addition, for ease of use, handles or other components can be welded onto the sealing plate to facilitate pulling out the sealing plate.

[0008] To optimize the above technical solution, further measures are taken, including: a fixed magnetic ring, which is fixedly sleeved on the outside of the housing. The fixed magnetic ring and the support plate attract each other to fix the support ring inside the housing. The fixed magnetic ring refers to a magnetic ring with a fixed position. The fixed magnetic ring and the movable magnetic ring refer to ring-shaped components composed of magnets, mainly magnets or electromagnets. Magnets are known to those skilled in the art, so their specific composition and working principle will not be further explained. In specific implementation, technicians can change the magnetic force by changing the composition, specifications, and power of the electromagnet. By using the fixed magnetic ring to attract the support ring to the outside and fix the support ring, it can be prevented from moving inside the housing after the weld point between the support ring and the housing is damaged. In addition, using magnetic attraction to fix the support ring facilitates the subsequent replacement of the polytetrafluoroethylene film.

[0009] As a further improvement to the above technical solution: the support ring is welded and fixed to the inside of the shell. The support ring is fixed to the shell by welding, which has a good fixing effect.

[0010] As an improvement to the aforementioned technical solution: an annular groove is formed on the edge of the through hole, and the annular groove matches the shape of the end of the heat exchange tube. The heat exchange tube is constrained by the annular groove, which can prevent the contact surface between the heat exchange tube and the support ring from becoming unstable when the condenser is working. In specific implementation, gaskets, rubber pads and other components can be added to improve its fit.

[0011] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

[0012] A. The foreign matter on both sides of the heat exchange tube can be scraped off by the gap between the annular scraper and the shell and heat exchange tube. The fixed magnet ring and the rotating ring work together to make the polytetrafluoroethylene film on the inside of the shell undulate, which can promote the peeling off of foreign matter on the inside of the shell.

[0013] B. The movable heat exchange tubes are exposed to the external environment by pulling out the sealing plate, which makes it easy to clean the heat exchange tubes directly;

[0014] C. It is easy to operate as there is no need to remove the condenser from the installed piping network. Attached Figure Description

[0026] The rotating ring 200 is rotatable inside the housing 100. A movable magnetic ring 201 is sleeved on the outside of the housing 100, and the movable magnetic ring 201 and the rotating ring 200 attract each other. The movable magnetic ring 201 and the housing 100 form a cylindrical pair. The Curie point temperature of the movable magnetic ring 201 is higher than the temperature of the housing 100.

The sealing plate 303 is connected to the contact plate 302 through the connecting post 306. An opening 305 matching the shape of the heat medium channel 101 is formed on the sealing plate 303 and the contact plate 302. The sealing plate 303 is detachably connected to the cavity 300.

[0028] Example 2: Please refer to Figure 1-7 The present invention provides a low-temperature condenser for a well water room in a livestock farm, comprising a shell 100, a rotating ring 200, a cavity 300, and a fixed magnet ring 400. Heat medium channels 101 are provided at both ends of the shell 100, a support ring 102 is fixedly disposed inside the shell 100, a through hole 103 is formed on the support ring 102, a connecting rod 104 is provided along the length of the shell 100 at the through hole 103, an annular scraper 105 is provided at the end of the connecting rod 104, and waste discharge holes 106 are opened on both sides of the shell 100.

[0029] The rotating ring 200 is rotatable inside the housing 100. A movable magnetic ring 201 is sleeved on the outside of the housing 100, and the movable magnetic ring 201 and the rotating ring 200 attract each other. The movable magnetic ring 201 and the housing 100 form a cylindrical pair. The Curie point temperature of the movable magnetic ring 201 is higher than the temperature of the housing 100. A roller 202 that forms a cylindrical pair with the rotating ring 200 is embedded inside the rotating ring 200. A polytetrafluoroethylene film 203 covering the surface of the rotating ring 200 is provided inside the housing 100.

[0030] A refrigerant channel 301 is formed on the side of the cavity 300. The cavity 300 also includes a contact plate 302 and a sealing plate 303. The contact plate 302 abuts against the surface of the shell 100 and covers a waste discharge hole 106. A heat exchange tube 304 is formed on the contact plate 302. The heat exchange tube 304 penetrates the shell 100 and forms a sliding pair with the shell 100 along the length direction of the shell 100. The end of the heat exchange tube 304 abuts against the support ring 102 and cooperates with the through hole 103. An annular groove 107 is formed on the edge of the through hole 103. The annular groove 107 and the heat exchange tube 304 are connected. The end shapes match, the heat exchange tube 304 surrounds the connecting rod 104 and the annular scraper 105 abuts against the inner wall of the heat exchange tube 304, the sealing plate 303 is connected to the contact plate 302 through the connecting column 306, and the sealing plate 303 and the contact plate 302 form an opening 305 that matches the shape of the heat medium channel 101. The fixing magnet ring 400 is fixedly sleeved on the outside of the housing 100. The fixing magnet ring 400 and the support ring 102 attract each other to realize that the support ring 102 is fixedly set in the housing 100. The sealing plate 303 and the cavity 300 are detachably connected.

[0031] Working principle: For Embodiment 1 and Embodiment 2, the cold medium is input from the cold medium channel 301 on one side, flows through the cavity 300, the heat exchange tube 304, and the through hole 103 on the support ring 102, and finally flows out from the cold medium channel 301 connected to the cavity 300 on the other side. The hot medium is input from the hot medium channel 101 on one side of the shell 100. The hot medium evenly surrounds the heat exchange tube 304 in the shell 100. During the process, heat can be exchanged between the cold medium and the hot medium to achieve condensation. The hot medium is finally output from the hot medium channel 101 on the other side.

[0032] After foreign matter adheres to the surface of the heat exchange tube 304, the sealing plate 303 is removed from the cavity 300, and then the sealing plate 303 is pulled outward. Since the heat exchange tube 304 and the shell 100 form a moving pair, the heat exchange tube 304 can move outward synchronously with the sealing plate 303. During the process, the foreign matter attached to the outer surface of the heat exchange tube 304 can be scraped off by the fitting gap between the heat exchange tube 304 and the shell 100. In addition, as the heat exchange tube 304 moves outward, the annular scraper 105 can scrape off the foreign matter attached to the inner wall of the heat exchange tube 304. These foreign matter can then flow out from the waste discharge hole 106. Furthermore, the heat exchange tube 304 is directly exposed to the external environment after being pulled outward, and can be further cleaned by technicians. During the process, it is not necessary to disassemble the condenser to separate it from the piping network.

[0033] After foreign matter adheres to the inner surface of the housing 100, a technician rotates and moves the movable magnetic ring 201 along the surface of the housing 100. At this time, the rotating ring 200 can rotate under the drive of the movable magnetic ring 201. During this process, the rotor on the rotating ring 200 can cause the polytetrafluoroethylene (PTFE) film 203 to undulate, causing the foreign matter to peel off from the PTFE film 203. The peeled foreign matter can then flow out from the waste discharge hole 106. In Embodiment 2, since the support ring 102 is magnetically fixed inside the housing 100 by the fixed magnetic ring 400, when the PTFE film 203 is damaged or has too much foreign matter to clean, it can be directly replaced.
