Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically to an evaporator water defrosting device. Background Technology

[0002] Evaporators are widely used in industrial refrigeration systems, and are a crucial component among the four main parts of a refrigeration system. However, in actual operation, due to factors such as reduced evaporation rate, some refrigerant liquid is not completely evaporated. At the end of the evaporator, the gradual decrease in refrigerant liquid can cause a phenomenon similar to low evaporation pressure, leading to icing.

[0003] The existing technology has the following defects or problems: The existing technology, disclosed in CN220582869U, relates to the field of evaporator technology, and specifically to an evaporator water defrosting device. It solves the problem of slow defrosting. It includes a heater, a transport pipe on the heater, a transport component on the transport pipe, one side of the transport component being attached to the outer side of the heating tube, and a water-filling component on the transport pipe. The fluid medium on the water-filling component is heated into steam after passing through the transport component and circulates along the side of the heating tube. This invention facilitates the circulation of water flow after it is heated into steam along the flow direction of the first and second one-way valves. When the steam circulates between the transport frame and the circulation sleeve, it heats the frost on the heating tube, thereby defrosting it. By using high temperature to hydrate the frost on the heating tube, the defrosting speed on the heating tube is effectively improved.

[0004] During the use of the aforementioned equipment, the water after defrosting is usually at a low temperature, and direct discharge would result in energy waste. However, in existing technologies, some evaporator water defrosting devices may cause water to corrode the metal surface of the evaporator during the defrosting process, leading to rust and corrosion of the evaporator over time, affecting its service life and performance.

[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-4In this embodiment: an evaporator defrosting device includes a base plate 1, an evaporator 2 fixedly connected to the top of the base plate 1, a water tank 3 fixedly connected to the top of the evaporator 2, two heating rods 4 disposed inside the water tank 3, two water outlet pipes 5 fixedly connected to the right side of the water tank 3, a water distribution pipe 6 fixedly connected to one end of each water outlet pipe 5, and conveying pipes 7 fixedly connected to the front and rear ends of the left side of the water distribution pipe 6, respectively. The exterior of the two conveying pipes 7 respectively contacts the front and rear sides of the evaporator 2, and a T-shaped pipe 8 fixedly connected to the bottom end of each conveying pipe 7. A collection bucket 9 is fixedly connected to the left side of the T-shaped pipe 8. The bottom end of the evaporator 2 is fixedly connected to the top left side of the base plate 1. The top of the collection tank 9 is fixedly connected to the protective box 10. The inside of the protective box 10 is fixedly connected to the water pump 11. The input end of the water pump 11 is fixedly connected to the suction pipe 12. The outside of the suction pipe 12 is fixedly connected to the inner wall of the bottom end of the protective box 10. The output end of the water pump 11 is fixedly connected to the second delivery pipe 13. The bottom end of the second delivery pipe 13 is fixedly connected to the inner wall of the top end of the protective box 10. The right side of the second delivery pipe 13 is fixedly connected to the left side of the water tank 3. The top front and rear sides of the base plate 1 are respectively provided with sliding grooves 14. The front and rear of the evaporator 2 are respectively provided with cleaning components.

[0026] In this embodiment, the heating rod 4 inside the water tank 3 heats the water in the water tank 3 to a suitable temperature, providing hot water for defrosting. The heated water flows into the distribution pipe 6 through the outlet pipe 5, and then is distributed to two delivery pipes 7. The hot water flows along the delivery pipes 7. Since the delivery pipes 7 are in contact with the front and rear sides of the evaporator 2, the heat of the hot water is transferred to the evaporator 2, thereby realizing the defrosting operation of the evaporator 2. The melted defrost water flows down the evaporator 2 to the T-shaped pipe and is finally collected in the collection bucket 9. The water pump 11 draws water from the collection bucket 9 through the suction pipe 12, and then transports the water back to the water tank 3 through the second delivery pipe 13.

[0027] Example 2

[0028] like Figure 1 - Figure 4 As shown, the cleaning assembly includes a protective frame 15. The top and rear sides of the protective frame 15 are respectively provided with two grooves 16. A fixing plate 17 is fixedly connected to the right side of the protective frame 15. A motor 18 is fixedly connected to the top of the fixing plate 17. A threaded rod 19 is fixedly connected to the output end of the motor 18. The outer side of the threaded rod 19 is rotatably connected to the inner wall of the protective frame 15. A protrusion 20 is threadedly connected to the outer side of the threaded rod 19. The inner wall of the protrusion 20 is threadedly connected to the outer side of the threaded rod 19. A sliding plate 21 is fixedly connected to the rear end of the protrusion 20. The upper and lower ends of the sliding plate 21 are slidably connected to the inner walls of the first groove 14 and the second groove 16, respectively. A scraper 22 is fixedly connected to the rear side of the sliding plate 21. The outer side of the scraper 22 is in contact with the outer side of the evaporator 2.

[0029] In this embodiment, when the motor 18 starts, its output end drives the threaded rod 19 to rotate. Since the inner wall of the protrusion 20 is threadedly connected to the outside of the threaded rod 19, when the threaded rod 19 rotates, according to the principle of threaded transmission, the protrusion 20 will move along the axial direction of the threaded rod 19. The protrusion 20 drives the sliding plate 21 at the rear end to move. The upper and lower ends of the sliding plate 21 slide in the first slide groove 14 and the second slide groove 16 respectively. In this way, the movement trajectory of the sliding plate 21 is restricted to a plane and can only slide along the direction of the first slide groove 14 and the second slide groove 16. The scraper 22 fixedly connected to the rear side of the sliding plate 21 will move together with the sliding plate 21. The outside of the scraper 22 is in contact with the outside of the evaporator 2. Therefore, during the movement of the scraper 22, impurities, residual frost, etc. on the surface of the evaporator 2 will be scraped off.

[0030] The working principle and usage process of this utility model are as follows: First, the heating rod 4 is powered on, and the heating rod 4 in the water tank 3 heats the water in the water tank 3 to a suitable temperature to provide hot water for defrosting. The heated water flows into the distribution pipe 6 through the outlet pipe 5, and then is distributed to two conveying pipes 7. The hot water flows along the conveying pipes 7. Since the conveying pipes 7 are in contact with the front and rear sides of the evaporator 2, the heat of the hot water is transferred to the evaporator 2, thereby realizing the defrosting operation of the evaporator 2. The melted defrost water flows along the evaporator 2 to the T-shaped pipe and is finally collected in the collection bucket 9. The water pump 11 sucks the water in the collection bucket 9 through the suction pipe 12, and then transports the water back to the water tank 3 through the second conveying pipe 13, realizing the recycling of water and saving water resources. Finally, the motor 18 is started, and its output end drives the threaded rod 19 to rotate. Since the inner wall of the protrusion 20 is threadedly connected to the outside of the threaded rod 19, when the threaded rod 19 rotates, according to the principle of threaded transmission, the protrusion 20 will move along the axial direction of the threaded rod 19. The protrusion 20 drives the sliding plate 21 at the rear end to move. The upper and lower ends of the sliding plate 21 slide in the first slide groove 14 and the second slide groove 16 respectively. In this way, the movement trajectory of the sliding plate 21 is restricted to a plane, and it can only slide along the direction of the first slide groove 14 and the second slide groove 16. The scraper 22 fixedly connected to the rear side of the sliding plate 21 will move together with the sliding plate 21. The outside of the scraper 22 is in contact with the outside of the evaporator 2. Therefore, during the movement of the scraper 22, it will scrape off the impurities, residual frost, etc. on the surface of the evaporator 2, thereby realizing the cleaning operation of the evaporator 2.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
