Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a refrigeration host. Background Art

[0002] Refrigeration units are essential components for air conditioning systems, cold storage, and industrial cooling. They cool the refrigerant and deliver cooling through a refrigeration cycle consisting of an evaporator, compressor, condenser, and throttle valve. In the evaporator, the refrigerant absorbs heat from the object being cooled. The compressor then draws in and compresses the vaporized refrigerant. Next, the refrigerant releases heat and condenses into a liquid in the condenser. Finally, the throttle valve reduces the pressure and temperature before returning it to the evaporator, completing the cycle.

[0003] In industrial refrigeration systems, the performance of the condenser has a crucial impact on the efficiency of the entire system. Over time, a layer of scale gradually accumulates on the inner walls of the condenser tubes. This accumulation of scale significantly reduces heat exchange efficiency, requiring the system to consume more energy to maintain normal operation, which undoubtedly increases system operating costs.

[0004] Currently, cleaning scale deposits is often complex and time-consuming. Common approaches include disassembling the equipment to directly remove the scale deposits, or using other descaling mechanisms to remove the scale deposits in real time. However, these descaling mechanisms often require electricity to operate, which increases the equipment's energy consumption. Utility Model Content

[0005] The purpose of the present invention is to provide a refrigeration host to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] As a further solution of the present invention: a plurality of condensing tubes are provided in the condenser, and the plurality of condensing tubes are arranged along the length direction of the condenser.

[0010] The working efficiency of the refrigeration equipment can be increased by providing multiple condensing tubes.

[0011] As a further solution of the present invention: the scraping assembly includes a scraping ring, and a scraping ring is sleeved on any one of the condensing tubes, and the scraping ring is dynamically connected to the driving assembly.

[0012] The scraper ring is sleeved on the condenser tube, and the scale on the condenser tube is scraped off by moving the scraper ring back and forth on the condenser tube.

[0013] As a further solution of the present invention: a driving rod is provided in the condenser, a scraper ring on the condensing tube is fixedly connected to the driving rod, and the driving rod is dynamically connected to the driving assembly.

[0014] The drive rod is arranged in the condenser, and the drive assembly drives the drive rod to reciprocate in the condenser, thereby driving the scraper ring to reciprocate.

[0015] As a further solution of the present invention: a plurality of scraper rings are provided on the condenser tube, and the plurality of scraper rings on the condenser tubes are directly connected to the driving rod or connected to the driving rod through adjacent scraper rings.

[0016] A plurality of scraper rings are arranged on the condenser tube, so each scraper ring only needs to work a short distance to complete the scraping of the condenser tube through the combined force of the plurality of scraper rings, which can reduce the reciprocating stroke of the driving rod.

[0017] As a further solution of the present invention: multiple drive plates are arranged on the drive rod along the length direction of the drive rod, the spacing between adjacent drive plates is not greater than the distance of the reciprocating motion of the drive rod, the drive plate is provided with a rectangular through groove for the circulation of cooling water, and the condenser is provided with a scraper ring arranged in coordination with the drive plate. The scraper ring close to the drive plate is directly fixedly connected to the drive plate through a connecting rod, and the remaining scraper rings are fixedly connected to adjacent scraper rings through connecting rods.

[0018] All scraper rings are fixedly connected to the driving rod through a driving plate. Through multiple driving plates, multiple scraping nets can be formed along the length of the driving rod, which is convenient for scraping scale from the condenser tube. At the same time, a rectangular through groove is opened on the driving plate so that the cooling water can pass through the rectangular through groove to avoid the driving plate affecting the flow of cooling water.

[0019] As a further solution of the present invention: one end of the driving rod extends to the outside of the condenser, the driving assembly includes a slide rail fixedly connected to the condenser, and one end of the driving rod is slidably connected to the slide rail.

[0020] By arranging the drive assembly outside the condenser, it is easy to install and easy to maintain.

[0021] As a further solution of the present invention: the end of the driving rod close to the slide rail is fixedly connected to a slider, the slider is slidably connected to the slide rail, the end of the slider away from the driving rod is provided with an elastic pull rope, the end of the elastic pull rope away from the slider is fixedly connected to the end of the slide rail away from the driving rod, and the end of the slider close to the driving rod is connected to a traction rope for driving the slider to slide on the slide rail.

[0022] By providing an elastic pull rope, the driving rod can be reset, and then reciprocate under the action of the elastic pull rope and the traction rope.

[0023] As a further solution of the present invention: a cooling water inlet and a cooling water outlet are provided at one end of the condenser, the cooling water inlet is located above the cooling water outlet and the slide rail, and a limiting hole is provided at the end of the slide rail close to the condenser for passing a traction rope, an impeller is provided in the cooling water inlet, one end of the rotating shaft of the impeller passes through the side wall of the cooling water inlet and extends to above the slide rail, the rotating shaft and the limiting hole are offset along the length direction of the driving rod, and the end of the rotating shaft away from the cooling water inlet is fixedly connected to a rotating rod, and one end of the traction rope is fixedly connected to one end of the rotating rod.

[0024] When there is water flow in the cooling water inlet, the water flow drives the impeller to rotate. When the impeller rotates, it drives the rotating shaft to rotate, thereby driving the rotating rod to rotate. When the rotating rod rotates, it drives one end of the traction rope to move in a circular trajectory, so that the other end of the traction rope pulls the slider to move, and cooperates with the tension of the elastic pull rope to make the slider move back and forth. When the slider moves back and forth, it drives the drive rod to move back and forth, thereby making the scraping assembly move back and forth to scrape off the scale on the condenser tube. The power of the driving assembly comes from the power of the water flow at the cooling water inlet, and there is no need to set up other electrical driving elements for driving, which saves energy and reduces consumption.

[0025] As a further solution of the present invention: blind holes are provided at both ends of the rotating rod, a spring is provided in the blind hole, the other end of the spring is fixedly connected to the impact rod, one end of the impact rod is slidably connected to the blind hole, the radius of the rotating rod is smaller than the distance from the axis of the rotating shaft to the outer wall of the condenser, and the distance from the axis of the rotating shaft to the outermost end of the impact rod in the natural state of the spring is greater than the distance from the axis of the rotating shaft to the outer wall of the condenser.

[0026] When the rotating rod rotates, the impact rod reciprocates and impacts the shell of the condenser, thereby causing the condenser to vibrate. Cooperating with the scraping of the scraping assembly, the scale on the condenser tube is easier to fall off, thereby improving the scale removal effect.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. This application utilizes the water flow at the cooling water inlet as a power source, and realizes automatic scraping of scale on the condenser tube and vibration of the condenser through a mechanical transmission device, thereby significantly improving the heat exchange efficiency and reducing the energy consumption of the system, reducing power consumption, and reducing operating costs;

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figure 1 In an embodiment of the utility model, a refrigeration host includes a refrigerator body 1 and a condenser 2 connected to the refrigerator body 1. A condensing tube 4 connected to the refrigerator body 1 is provided in the condenser 2. In this embodiment, a plurality of condensing tubes 4 are provided in the condenser 2. The plurality of condensing tubes 4 are arranged along the length direction of the condenser 2. By setting a plurality of condensing tubes 4, the working efficiency of the refrigeration equipment can be increased.

[0040] like Figure 2 As shown, a scraping assembly for removing scale on the condenser tube 4 is provided in the condenser 2. The scraping assembly includes a scraper ring 5. A scraper ring 5 is sleeved on any condenser tube 4. The scraper ring 5 is power-connected to the drive assembly 3. The scraper ring 5 is sleeved on the condenser tube 4. The scraper ring moves back and forth on the condenser tube 4 to complete the scraping of scale on the condenser tube 4. In this embodiment, a plurality of scraper rings 5 ​​are provided on the condenser tube 4.

[0041] The condenser 2 is connected to a driving assembly 3, and the driving assembly 3 is power-connected to the scraping assembly for driving the scraping assembly to reciprocate along the length direction of the condenser tube 4. In this embodiment, a driving rod 7 is provided in the condenser 2, and the scraper ring 5 on the condenser tube 4 is fixedly connected to the driving rod 7. The driving rod 7 is power-connected to the driving assembly 3. Multiple scraper rings 5 ​​on multiple condenser tubes 4 are directly connected to the driving rod 7 or connected to the driving rod 7 through adjacent scraper rings 5. Multiple scraper rings 5 ​​are provided on the condenser tube 4. Multiple scraper rings 5 ​​are provided on the condenser tube 4. Therefore, each scraper ring 5 only needs to work a short distance to complete the scraping of the condenser tube 4 through the combined force of multiple scraper rings 5, which can reduce the reciprocating stroke of the driving rod 7.

[0042] like Figure 3As shown, a plurality of drive plates 6 are arranged on the drive rod 7 along the length direction of the drive rod 7, and the spacing between adjacent drive plates 6 is no greater than the distance of the reciprocating motion of the drive rod 7. A rectangular through-slot 601 for the circulation of cooling water is provided on the drive plate 6. A scraper ring 5 arranged in coordination with the drive plate 6 is arranged on the condenser tube 4. The scraper ring 5 close to the drive plate 6 is directly fixedly connected to the drive plate 6 via the connecting rod 8, and the remaining scraper rings 5 ​​are fixedly connected to the adjacent scraper rings 5 ​​via the connecting rod 8. All the scraper rings 5 ​​are fixedly connected to the drive rod 7 via the drive plate 6. Through the multiple drive plates 6, multiple scraping nets can be formed along the length direction of the drive rod 7 to facilitate the scraping of scale on the condenser tube 4. At the same time, a rectangular through-slot 601 is provided on the drive plate 6 to allow cooling water to pass through the rectangular through-slot 601, thereby preventing the drive plate 6 from affecting the flow of cooling water.

[0043] like Figure 4 As shown, one end of the drive rod 7 extends to the outside of the condenser 2, and the drive assembly 3 includes a slide rail 301 fixedly connected to the condenser 2. One end of the drive rod 7 is slidably connected to the slide rail 301. By setting the drive assembly 3 outside the condenser 2, it can be easily installed and maintained.

[0044] The end of the driving rod 7 close to the slide rail 301 is fixedly connected to the slider 302, and the slider 302 is slidably connected to the slide rail 301. The end of the slider 302 away from the driving rod 7 is provided with an elastic pull rope 303, and the end of the elastic pull rope 303 away from the slider 302 is fixedly connected to the end of the slide rail 301 away from the driving rod 7. The end of the slider 302 close to the driving rod 7 is connected to a traction rope 304 for driving the slider 302 to slide on the slide rail 301. One end of the condenser 2 is provided with a cooling water inlet 201 and a cooling water outlet 202. The cooling water inlet 201 is located above the cooling water outlet 202 and the slide rail 301. The end of the slide rail 301 close to the condenser 2 is provided with a limiting hole for the traction rope 304 to pass through. An impeller 307 is provided in the cooling water inlet 201. One end of the rotating shaft 306 of the impeller 307 passes through the side wall of the cooling water inlet 201 and extends to the top of the slide rail 301. The rotating shaft 306 and the limiting hole are offset along the length direction of the driving rod 7. The end of the rotating shaft 306 away from the cooling water inlet 201 is fixedly connected to the rotating rod 305, and one end of the traction rope 304 is fixedly connected to one end of the rotating rod 305.

[0045] When there is water flow in the cooling water inlet 201, the water flow drives the impeller 307 to rotate. When the impeller 307 rotates, it drives the rotating shaft 306 to rotate, thereby driving the rotating rod 305 to rotate. When the rotating rod 305 rotates, it drives one end of the traction rope 304 to move in a circular trajectory, so that the other end of the traction rope 304 pulls the slider 302 to move, and cooperates with the tension of the elastic pull rope 303 to enable the slider 302 to move back and forth. When the slider 302 moves back and forth, it drives the drive rod 7 to move back and forth, thereby causing the scraping assembly to move back and forth to scrape off the scale on the condenser 4. The power of the driving assembly 3 comes from the power of the water flow at the cooling water inlet 201, and there is no need to set up other electrical driving elements for driving, which plays a role in energy saving and consumption reduction.

[0046] like Figure 5 As shown, both ends of the rotating rod 305 are provided with blind holes, and a spring 309 is provided in the blind hole. The other end of the spring 309 is fixedly connected to the impact rod 308, and one end of the impact rod 308 is slidably connected to the blind hole. The radius of the rotating rod 305 is smaller than the distance from the axis of the rotating shaft 306 to the outer wall of the condenser 2. In the natural state of the spring 309, the distance from the axis of the rotating shaft 306 to the outermost end of the impact rod 308 is greater than the distance from the axis of the rotating shaft 306 to the outer wall of the condenser 2. When the rotating rod 305 rotates, the impact rod 308 reciprocates and strikes the shell of the condenser 2, thereby causing the condenser 2 to vibrate. In combination with the scraping of the scraping assembly, the scale on the condenser tube 4 is more easily removed, thereby improving the scale removal effect.

[0047] When the refrigeration host of this embodiment is working, high-temperature and high-pressure refrigerant vapor enters the condenser 2 and is dispersed into multiple condensing tubes 4. The refrigerant vapor releases heat and condenses into high-pressure liquid. The cooling water is input into the condenser 2 through the cooling water inlet 201, absorbs the heat emitted by the condensing tube 4, and is heated before being discharged through the cooling water outlet 202. After the condensing tube 4 has been used for a long time, scale adheres to the outer wall of the condensing tube 4. When the refrigeration host is working, there is water flow in the cooling water inlet 201. The water flow drives the impeller 307 to rotate. When the impeller 307 rotates, it drives the rotating shaft 306 to rotate, thereby driving the rotating rod 305 to rotate. When the rod 305 rotates, it drives one end of the traction rope 304 to move in a circular trajectory, so that the other end of the traction rope 304 pulls the slider 302 to move, and cooperates with the tension of the elastic pull rope 303 to enable the slider 302 to move back and forth. When the slider 302 moves back and forth, it drives the driving rod 7 to move back and forth, so that the scraping assembly moves back and forth to scrape the scale on the condenser 4. At the same time, when the rotating rod 305 rotates, the impact rod 308 reciprocates and impacts the shell of the condenser 2, so that the condenser 2 vibrates, and cooperates with the scraping of the scraping assembly to make the scale on the condenser 4 fall off more easily, thereby improving the scale removal effect.
