Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically to an air conditioning waste heat recovery pipeline device. Background Technology

[0002] Air conditioners, as commonly used temperature control devices in daily production and life, generate a lot of waste heat in the outdoor unit's condenser pipes and exhaust system during cooling and heating operations. Most of this waste heat is directly discharged into the external environment, which not only causes a lot of energy waste, but also aggravates thermal pollution in the surrounding environment.

[0003] Existing air conditioning waste heat recovery piping systems suffer from scale buildup on the inner walls due to the presence of calcium, magnesium, and other minerals in the medium, which, after prolonged operation, negatively impacts heat exchange efficiency. Therefore, there is an urgent need to develop a new air conditioning waste heat recovery piping system to overcome these shortcomings in current applications. Summary of the Invention

[0019] The retention box is fixedly connected to the material guide cover at the bottom of the heat exchange tube by a support rod, and the retention box has two mutually separated receiving cavities, namely, receiving cavity 2 and receiving cavity 1.

[0020] The second intermediate circulation pipe is used to accommodate the communication between cavity two and inner cavity four.

The discharge end circulation pipe one is connected to the inner cavity three, and the discharge end circulation pipe two is connected to the inner cavity four. A collection pipe is respectively disposed on the discharge end circulation pipe one and the discharge end circulation pipe two.

[0024] As a further aspect of the present invention: the cleaning component includes:

[0025] A cleaning cover is fixedly installed on a lifting plate above the turntable. A drive plate is rotatably installed inside the cleaning cover, and the drive plate is provided with multiple sets of blades.

[0026] An air pump used to blow the blades and drive the drive disc to rotate, the air pump's outlet pipe extending into the cleaning hood;

[0027] And a telescopic plate, wherein multiple sets of telescopic plates are provided at the bottom of the drive disk, and the drive disk has through holes that communicate with the telescopic plates, and multiple air jet holes are provided on the side wall of the telescopic plate.

[0028] As a further aspect of the present invention: a telescopic pipe and a drain pipe are sequentially installed on the drain hole, the end of the drain pipe is connected to a round hole on the lifting plate, a positioning rod is fixed inside the drain hole, a top rod is fixedly installed on the positioning rod, and a sealing plug for sealing the drain pipe is provided at the end of the top rod.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] This invention achieves an intermittent operating mode for the heat exchange tubes by incorporating a rotating support assembly and a retention-type feed / discharge section. After a set of heat exchange tubes has been operating for a period of time, a telescopic cylinder drives a slider and a lifting plate to separate the guide cover from the heat exchange tubes, thereby removing the used heat exchange tubes from their working position for cleaning, while the other heat exchange tubes continue to operate. This design avoids the formation of scale on the inner wall of the pipes due to long-term medium circulation, as seen in existing technologies, thus effectively maintaining the heat exchange efficiency of the device.

[0031] This invention utilizes high-pressure gas to drive blades that rotate a drive disc. Simultaneously, high-pressure gas enters a telescopic plate, causing it to extend and exiting through jet holes on the side wall. This, combined with the rotational motion, powerfully flushes the inner wall of the heat exchange tubes. This device can automatically clean the heat exchange tubes at a cleaning station without shutting down the air conditioning system, eliminating the need for manual disassembly and significantly improving operational continuity and maintenance convenience.

[0032] By incorporating a retention chamber and dual-chamber heat exchange tubes (inner chamber one and inner chamber two), this device achieves separate flow of the refrigerant and the heat exchange medium (such as water). The refrigerant and heat exchange medium undergo pre-heat exchange in the retention chamber before entering the heat exchange tubes for main heat exchange, optimizing the heat exchange process and improving energy recovery efficiency. Simultaneously, the outlet manifold design facilitates the return of the treated refrigerant to the compressor and the introduction of the heated medium into the waste heat recovery system.

[0033] This invention features a drain hole at the bottom of the housing, along with a telescopic pipe, a drain pipe, and an automatic sealing mechanism (including a positioning rod, a top rod, and a sealing plug). During cleaning, the lifting plate moves the drain pipe downwards, offsetting it from the sealing plug for drainage. Under normal operation, the sealing plug effectively seals the drain outlet, preventing media leakage and ensuring the safety and environmental friendliness of the device.

Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0049] The present invention will be further explained below with reference to specific embodiments.

[0050] Please see Figures 1-10 An embodiment of the present invention provides an air conditioning waste heat recovery pipeline device, comprising:

[0051] The housing 1 has a drain hole 3 at its bottom;

[0052] A heat exchange mechanism located inside the housing 1, the heat exchange mechanism including a rotary support assembly and a waste heat recovery assembly disposed on the rotary support assembly;

[0053] The heat exchange mechanism further includes a connecting component, which includes a retention feed section and a discharge section disposed at both ends of the waste heat recovery component, and the discharge section is also provided with a cleaning component for cleaning the waste heat recovery component.

[0054] In embodiments of the present invention, during operation, the retention-type feed section allows refrigerant to be introduced from the refrigerant outlet of the condenser in the outdoor unit of the air conditioner into the waste heat recovery component. It also allows heat exchange media (water, heat transfer fluid, etc.) to enter the waste heat recovery component, where the refrigerant and heat exchange media complete heat exchange. The discharge section guides the refrigerant back to the compressor inlet of the outdoor unit, achieving a circulation function. Simultaneously, the discharge section allows the heat exchange media to be introduced into an external air conditioning waste heat recovery system, realizing waste heat utilization. A cleaning component allows for the regular cleaning of the waste heat recovery component after use. Regular cleaning improves heat exchange efficiency, and the drain hole 3 can discharge the debris generated during cleaning. Among them, there are various existing air conditioning waste heat recovery systems that can collect, transport and reuse waste heat (such as heating, hot water supply, etc.), which are conventional systems known to those skilled in the art and will not be described in detail here. Compared with the prior art, the present invention avoids the problem that existing air conditioning waste heat recovery pipe devices will form scale on the inner wall surface of the pipe after long-term circulation due to the calcium, magnesium and other minerals contained in the medium, which affects the heat exchange effect.

[0055] In one embodiment of the present invention, please refer to Figures 1-10 The rotating support assembly includes:

[0056] A support shaft 21 is rotatably installed inside the housing 1, and a motor 10 for driving the support shaft 21 to rotate is provided inside the housing 1;

[0057] Turntable 16, which is fixedly mounted on support shaft 21, and support shaft 21 has multiple round holes;

[0058] The waste heat recovery assembly includes a heat exchange tube 23, which is fixedly installed in the circular hole of the turntable 16, and at least three sets of heat exchange tubes 23 are provided. The heat exchange tube 23 has a mutually separated inner cavity 25 and inner cavity 26.

[0059] Both the retention-type feed section and the discharge section include:

[0060] A guide rail 4 is fixedly installed inside the housing 1. Two sets of sliders 15 are slidably installed inside the guide rail 4, and the two sets of sliders 15 are symmetrically arranged inside the guide rail 4.

[0061] A fixing block 6 is fixed inside the guide rail 4. The fixing block 6 is located between two sets of sliders 15, and a telescopic cylinder 5 for driving the guide rail 4 to move is also provided inside the fixing block 6.

[0062] The lifting plate 14 is provided in two sets, and the two sets of lifting plates 14 are respectively fixed on two sets of sliders 15.

[0063] A material guide cover 17 is snapped onto the end of the heat exchange tube 23. The material guide cover 17 is fixedly installed on the lifting plate 14 by a fixing ring 24. The material guide cover 17 has an inner cavity 30 and an inner cavity 4 31. The inner cavity 30 is connected to the inner cavity 1 25, and the inner cavity 4 31 is connected to the inner cavity 2 26.

[0064] The retention-type feed section also includes:

[0065] The retention box 13 is fixedly connected to the guide cover 17 at the bottom of the heat exchange tube 23 by a support rod 29, and the retention box 13 has a mutually separated receiving cavity 33 and receiving cavity 32.

[0066] The second intermediate circulation pipe 28 is used to accommodate the communication between the second cavity 33 and the fourth inner cavity 31.

[0067] A mid-end circulation pipe 27 is used to accommodate the communication between cavity 32 and inner cavity 30.

[0068] The feed end circulation pipe 11 and feed end circulation pipe 2 12 are fixedly installed on the housing 1. The feed end circulation pipe 11 is connected to the second receiving cavity 33, and the feed end circulation pipe 2 12 is connected to the first receiving cavity 32. Solenoid valves are provided on the feed end circulation pipe 11, the feed end circulation pipe 2 12, the middle circulation pipe 1 27 and the middle circulation pipe 2 28.

[0069] The discharge section also includes a discharge end circulation pipe 18 and a discharge end circulation pipe 29 disposed on the material guide cover 17 at the top of the heat exchange tube 23. The discharge end circulation pipe 18 is connected to the inner cavity 30, and the discharge end circulation pipe 29 is connected to the inner cavity 41. A collecting pipe 20 is respectively provided on the discharge end circulation pipe 18 and the discharge end circulation pipe 29. The collecting pipe 20 is used for communication between the discharge end circulation pipe 18 and the discharge end circulation pipe 29 on adjacent material guide covers 17. A solenoid valve is provided on the discharge end circulation pipe 18 and the discharge end circulation pipe 29.

[0070] In this embodiment, during heat exchange, a single set of heat exchange tubes 23 operates. The inlet circulation pipe 11 and the inlet circulation pipe 22 respectively introduce the condenser and heat exchange medium into the receiving chamber 2 33 and the receiving chamber 1 32, respectively, completing pre-heat exchange in the retention tank 13. The middle circulation pipe 28 and the middle circulation pipe 27 introduce the condenser and heat exchange medium from the retention tank 13 into the inner chamber 26 and the inner chamber 1 25, completing heat exchange in the heat exchange tubes 23. After heat exchange, the condenser and heat exchange medium are discharged through the outlet circulation pipe 2 19 and the outlet circulation pipe 18, respectively. The condenser is discharged through the outlet circulation pipe. The manifold 20 connected to pipe 219 returns to the compressor. The heat exchange medium enters the air conditioning waste heat recovery system through the manifold 20 connected to the discharge end circulation pipe 18, completing waste heat recovery and refrigerant circulation. After the heat exchange tube 23 has been working for a period of time, the telescopic cylinder 5 will push the two sets of sliders 15 to move, so that the lifting plate 14 drives the guide cover 17 to separate from the heat exchange tube 23. Before separation, the solenoid valves on the feed end circulation pipe 11 and the feed end circulation pipe 22 are closed. At the same time as closing, all the liquid in the heat exchange tube 23 is extracted, and the used heat exchange tube 23 can be moved to the cleaning station to complete the cleaning work without stopping the machine.

[0071] In one embodiment of the present invention, please refer to Figures 1-10 The cleaning component includes:

[0072] A cleaning cover 22 is fixedly installed on a lifting plate 14 above a turntable 16. A drive plate 35 is rotatably installed inside the cleaning cover 22, and multiple sets of blades 34 are provided on the drive plate 35.

[0073] An air pump 2 is used to blow the blades 34 and drive the drive disc 35 to rotate. The air outlet pipe of the air pump 2 extends into the cleaning hood 22.

[0074] And the telescopic plate 36, which has multiple sets at the bottom of the drive disk 35, and the drive disk 35 has through holes that communicate with the telescopic plate 36. Multiple jet holes are opened on the side wall of the telescopic plate 36. When high-pressure gas enters the telescopic plate 36 from the drive disk 35, the telescopic plate 36 will extend, and the high-pressure gas will be sprayed out from the jet holes onto the inner wall of the heat exchange tube 23, effectively removing dirt. When the air pump 2 stops working, the spring built into the telescopic plate 36 will reset the telescopic plate 36.

[0075] The drain hole 3 is also equipped with a telescopic pipe 9 and a drain pipe 8 in sequence. The end of the drain pipe 8 is connected to the round hole on the lifting plate 14. A positioning rod 37 is also fixed inside the drain hole 3. A top rod 39 is fixedly installed on the positioning rod 37, and a sealing plug 38 for sealing the drain pipe 8 is provided at the end of the top rod 39.

[0076] In this embodiment, the high-pressure gas ejected by the air pump 2 will drive the blades 34 to rotate the drive plate 35. After the high-pressure gas enters the telescopic plate 36 through the drive plate 35, it will cause the telescopic plate 36 to extend. The high-pressure gas will be ejected from the jet hole onto the inner wall of the heat exchange tube 23. At the same time, the drive plate 35 will drive the telescopic plate 36 to rotate, effectively removing dirt. When the air pump 2 stops working, the spring built into the telescopic plate 36 will cause the telescopic plate 36 to return to its original position. After cleaning is completed, the lifting plate 14 will move the drain pipe 8 downward so that the bottom of the drain pipe 8 is misaligned with the sealing plug 38. At this time, impurities can be discharged through the drain pipe 8 and the telescopic pipe 9.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
