Description

Technical Field

[0001] This utility model relates to the field of high-temperature water heaters, specifically a vortex high-temperature water heater. Background Technology

[0002] A high-temperature water heater is a device that uses heat pump or electric heating technology to provide high-temperature hot water. It is widely used in industrial, commercial and civil fields. The high-temperature water heater uses a compressor to drive the refrigerant circulation, realizing the transfer of heat from the low-temperature environment to the high-temperature water. The refrigerant absorbs low-temperature heat from the air / environment in the evaporator and vaporizes into gas. The gas is compressed into a high-temperature and high-pressure state by the compressor. The high-temperature refrigerant releases heat to the water in the condenser, and the water temperature rises to the set value. It can transfer 3 parts of ambient heat energy for every 1 unit of electrical energy consumed, with an energy efficiency ratio of over 400%.

[0003] High-temperature water heaters have become core equipment for industrial thermal energy transformation due to their high efficiency, energy saving and environmental protection advantages. However, with the use of water heaters, subsequent maintenance has become a major challenge. Industrial water contains a large number of impurities and is hard, resulting in a large amount of scale buildup, which seriously affects heating efficiency and keeps subsequent maintenance costs high. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a vortex high-temperature water heater to solve the technical problems of industrial water containing a large number of impurities and hard water, which leads to the formation of a large amount of scale, seriously affecting heating efficiency and subsequent maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scroll high-temperature water heater, comprising a scroll compressor, a pipe fixedly connected to the output end of the scroll compressor, an air inlet fixedly connected to the end of the pipe, a heating coil fixedly connected to one end of the air inlet, an annular scraper slidably connected to the outer wall of the heating coil, a scraper holder fixedly connected to the outer end of the annular scraper, a telescopic rod rotatably connected to one end of the scraper holder, a connecting ring rotatably connected to one end of the telescopic rod, a lead screw rotatably connected inside the connecting ring, the lead screw penetrating a sealing cover, a bracket fixedly connected to the upper end of the sealing cover, a motor fixedly connected to the upper end of the bracket, and the output end of the motor fixedly connected to the lead screw.

[0006] By adopting the above technical solution, the scroll compressor is powered on and starts. Low-pressure, room-temperature gaseous refrigerant is introduced into the scroll compressor and transformed into high-pressure, high-temperature gaseous refrigerant. This refrigerant flows through a pipe to the inlet and then into the heating coil. The heating coil is coiled and laid flat at the bottom of the water storage tank. The coiled shape allows the refrigerant inside the coil more time to exchange heat with the cold water in the tank. When the heating time exceeds the specified range to reach the target calorific value, the motor power is switched on, and the motor starts. A lead screw is fixedly connected to the motor output, and the motor drives the lead screw to rotate. A connecting ring is rotatably connected to the lead screw. The connecting ring moves up and down with the rotation of the lead screw. One end of the connecting ring is rotatably connected to a telescopic rod, and the other end of the telescopic rod is rotatably connected to a blade holder. An annular scraper is fixedly connected inside the blade holder. The blade of the annular scraper contacts the heating coil. The rotation of the connecting ring drives the blade holder to move in a circle from the air inlet position along the heating coil. During this process, the telescopic rod is passively retracted and changes its angle as the connecting ring rises and the blade holder moves inward. The blade of the annular scraper presses against the surface of the heating coil during the movement of the blade holder, removing the scale on the surface of the heating coil.

[0007] Furthermore, an air outlet is fixedly connected to the end of the heating coil. The air outlet penetrates the bottom of the water storage tank, and the outer wall of the air outlet is fixedly connected to the water storage tank. A pipe is fixedly connected to the inner wall of the air outlet. An expansion valve is connected to one end of the pipe. The expansion valve is fixedly connected to the drying bottle through the pipe. The drying bottle is fixedly connected to the scroll compressor through the pipe.

[0008] By adopting the above technical solution, the high-temperature and high-pressure gaseous refrigerant exchanges heat with the cold water in the storage tank through the heating coil and flows to the gas outlet. The high-temperature and high-pressure gaseous refrigerant is transformed into a normal-temperature and high-pressure liquid-water mixed refrigerant. The normal-temperature and high-pressure liquid-water mixed refrigerant flows through the pipeline to the expansion valve. Through the expansion valve, the normal-temperature and high-pressure liquid-water mixed refrigerant is transformed into a low-pressure and normal-temperature gaseous refrigerant and continues to flow to the drying bottle for drying and filtration. After that, the low-pressure and normal-temperature gaseous refrigerant flows back into the scroll compressor for the next cycle until the calorific value detected by the integrated sensor in the storage tank reaches the standard and then stops.

[0009] Furthermore, the air inlet penetrates the outer wall of the water storage tank, and the outer wall of the air inlet is fixedly connected to the inside of the water storage tank. A sealing cover is fixedly connected to the upper surface of the water storage tank, and a comprehensive sensor is fixedly connected to the bottom surface of the sealing cover. The comprehensive sensor plays the role of monitoring the water level, water temperature, and machine operating status.

[0010] By adopting the above technical solution, the water inlet valve is opened, and water is added to the water storage tank through the water inlet on the sealed cover until the water level is detected by the integrated sensor and then the water inlet valve is closed.

[0011] Furthermore, the water storage tank is provided with a water outlet at the bottom, and a water outlet valve is fixedly connected to the water storage tank through the water outlet. The water outlet valve controls the water flow rate.

[0012] By adopting the above technical solution, after the integrated sensor in the water storage tank detects that the calorific value meets the standard, the power supply of the scroll compressor is turned off, and the water outlet valve is opened through the integrated sensor, so that hot water can flow out of the water storage tank through the outlet and enter the external equipment.

[0013] In summary, the present invention has the following main advantages:

[0014] By designing the heating coil to be coiled and installed at the bottom of the water storage tank, the heat exchange time between the refrigerant and the cold water in the tank is effectively extended, thus improving heating efficiency.

[0015] The heating time is monitored by a comprehensive sensor. When the heating time exceeds the limit, indicating that scale accumulation is affecting heating efficiency, the descaling mechanism is automatically activated. The motor drives the lead screw to rotate, which in turn moves the connecting ring up and down. This, in turn, pushes the blade holder equipped with a ring scraper through the telescopic rod. The scraper moves precisely in a circular motion along the curvature path of the heating coil, closely adhering to the surface of the coil. The mechanical scraping effectively removes the hard scale layer attached to the coil, significantly restoring the heat exchange efficiency of the coil. The descaling process is fully automated, requiring no manual intervention or chemical agents. It is environmentally friendly and safe to operate. After descaling, the telescopic rod moves in the opposite direction with the connecting ring, and the motor reverses to automatically reset the blade holder, preparing it for the next operation. The ring scraper has a large contact area with the coil and fits tightly, thoroughly cleaning stubborn scale from the surface of complex and curved pipes. This solves the problem of scale buildup in heat exchangers under industrial hard water conditions, which leads to increased energy consumption and decreased heating efficiency. It extends the service life of the equipment and reduces maintenance costs and energy consumption. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] A type of vortex high-temperature water heater, such as Figure 1-5 As shown, it includes a scroll compressor 1, with a pipe 9 fixedly connected to the output end of the scroll compressor 1, an air inlet 401 fixedly connected to the end of the pipe 9, and a heating coil fixedly connected to one end of the air inlet 401.

[0025] When the power supply to the scroll compressor 1 is turned on, the scroll compressor 1 is powered on and started. Low-pressure, room-temperature gaseous refrigerant is introduced into the scroll compressor 1 and converted into high-pressure, high-temperature gaseous refrigerant. It flows through the pipe 9 to the air inlet 401 and then into the heating coil 4 through the air inlet 401. The heating coil 4 is coiled and laid flat at the bottom of the water storage tank 6. The coiled shape allows the refrigerant in the coil to have more time to exchange heat with the cold water in the water storage tank 6.

[0026] A ring scraper 501 is slidably connected to the outer wall of the heating coil 4. A scraper holder 5 is fixedly connected to the outer end of the ring scraper 501. A telescopic rod 502 is rotatably connected to one end of the scraper holder 5. A connecting ring 503 is rotatably connected to one end of the telescopic rod 502. A lead screw 504 is rotatably connected inside the connecting ring 503. The lead screw 504 passes through the sealing cover 601. A bracket 506 is fixedly connected to the upper end of the sealing cover 601. A motor 507 is fixedly connected to the upper end of the bracket 506. The output end of the motor 507 is fixedly connected to the lead screw 504.

[0027] When the heating time exceeds the specified range to reach the required calorific value, the power supply to motor 507 is turned on, and motor 507 starts. A lead screw 504 is fixedly connected to the output end of motor 507, and motor 507 drives lead screw 504 to rotate. A connecting ring 503 is rotatably connected to lead screw 504, and the connecting ring 503 moves up and down with the rotation of lead screw 504. One end of connecting ring 503 is rotatably connected to telescopic rod 502, and one end of telescopic rod 502 is rotatably connected to knife holder 5. A ring scraper 501 is fixedly connected inside knife holder 5. The cutting edge of ring scraper 501 contacts heating coil 4. When connecting ring 503 rotates, it drives knife holder 5 to move in a circle from air inlet 401 along heating coil 4. During this process, telescopic rod 502 passively retracts and changes angle as connecting ring 503 rises and knife holder 5 moves inward. As knife holder 5 moves, the cutting edge of ring scraper 501 presses against the surface of heating coil 4 to remove scale from the surface of heating coil 4.

[0028] Please see Figure 1 , Figure 3 and Figure 4 The heating coil 4 is fixedly connected to an air outlet 402 at its end. The air outlet 402 penetrates the bottom of the water storage tank 6 and is fixedly connected to the outer wall of the air outlet 402 and the water storage tank 6. A pipe 9 is fixedly connected to the inner wall of the air outlet 402. An expansion valve 3 is connected to one end of the pipe 9. The expansion valve 3 is fixedly connected to the drying bottle 2 through the pipe 9. The drying bottle 2 is fixedly connected to the scroll compressor 1 through the pipe 9.

[0029] The high-temperature, high-pressure gaseous refrigerant exchanges heat with the cold water in the water tank 6 through the heating coil 4 and flows to the gas outlet 402. The high-temperature, high-pressure gaseous refrigerant is transformed into a normal-temperature, high-pressure liquid-water mixture refrigerant. The normal-temperature, high-pressure liquid-water mixture refrigerant flows through the pipe 9 to the expansion valve 3. Through the expansion valve 3, the normal-temperature, high-pressure liquid-water mixture refrigerant is transformed into a low-pressure, normal-temperature gaseous refrigerant and continues to flow to the drying bottle 2 for drying and filtration. After that, the low-pressure, normal-temperature gaseous refrigerant flows back into the scroll compressor 1 for the next cycle until the integrated sensor 505 in the water tank 6 detects that the calorific value meets the standard and then stops.

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A sealing cover 601 is fixedly connected to the upper end of the water storage tank 6, and a comprehensive sensor 505 is fixedly connected to the bottom of the sealing cover 601. The comprehensive sensor 505 plays the role of monitoring the water level, water temperature and machine working status.

[0031] The process involves opening the inlet valve 7 and adding water to the storage tank 6 through the inlet on the sealing cover 601 until the integrated sensor 505 detects that the water level has reached the standard, at which point the inlet valve 7 is closed.

[0032] Please see Figure 2 and Figure 4 The water storage tank 6 has a water outlet at the bottom, and the water storage tank 6 is fixedly connected to the water outlet valve 8 through the water outlet. The water outlet valve 8 controls the water flow rate of the water outlet.

[0033] Once the integrated sensor 505 inside the water storage tank 6 detects that the calorific value meets the standard, it shuts off the power to the scroll compressor 1 and opens the outlet valve 8 through the integrated sensor 505, allowing hot water to flow out of the water storage tank 6 and into external equipment.

[0034] The working principle of this utility model is as follows: Open the water inlet valve 7 and add water to the water storage tank 6 through the water inlet on the sealing cover 601 until the integrated sensor 505 detects that the water level has reached the standard. Then close the water inlet valve 7 and connect the power supply to the scroll compressor 1, causing the scroll compressor 1 to start. Low-pressure, room-temperature gaseous refrigerant is introduced into the scroll compressor 1, where it is converted into high-pressure, high-temperature gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant flows through the pipe 9 to the air inlet 401 and then into the heating coil 4. The heating coil 4 is coiled and laid flat at the bottom of the water storage tank 6. The coiled shape allows the refrigerant inside the coil more time to exchange heat with the cold water in the water storage tank 6, and the coiled contact area... Larger, high-temperature, high-pressure gaseous refrigerant exchanges heat with cold water in the water tank 6 through the heating coil 4 and flows to the gas outlet 402. The high-temperature, high-pressure gaseous refrigerant is transformed into a normal-temperature, high-pressure liquid-water mixture refrigerant. The normal-temperature, high-pressure liquid-water mixture refrigerant flows through the pipe 9 to the expansion valve 3. Through the expansion valve 3, the normal-temperature, high-pressure liquid-water mixture refrigerant is transformed into a low-pressure, normal-temperature gaseous refrigerant and continues to flow to the drying bottle 2 for drying and filtration. After that, the low-pressure, normal-temperature gaseous refrigerant flows back into the scroll compressor 1 for the next cycle until the comprehensive sensor 505 in the water tank 6 detects that the calorific value meets the standard and stops. The comprehensive sensor 505 then opens the water outlet valve 8, allowing hot water to flow out of the water tank 6 and into external equipment.

[0035] Industrial water contains many impurities and is hard. The water heater heats the cold water in the storage tank 6 through the heating coil 4. A large amount of impurities adhere to the heating coil 4 during heating, forming scale. After repeated use, the scale builds up to a certain thickness, significantly reducing the heat exchange efficiency of the heating coil 4. The integrated sensor 505 detects and records the heating time during each operation. If the time to reach the required calorific value exceeds the specified range, the power to the motor 507 is activated, and the motor 507 starts. A lead screw 504 is fixedly connected to the output end of the motor 507, driving the lead screw 504 to rotate. A connecting ring 503 is rotatably connected to the lead screw 504, moving up and down with the rotation of the lead screw 504. One end of the connecting ring 503 is rotatably connected to a telescopic rod 502, and the other end of the telescopic rod 502 is rotatably connected to a tool holder 5. The tool holder 5 is internally fixed... A ring scraper 501 is fixedly connected, and the cutting edge of the ring scraper 501 contacts the heating coil 4. The connecting ring 503 rotates, which drives the blade holder 5 to move in a circle from the air inlet 401 along the heating coil 4 through the telescopic rod 502. During this process, the telescopic rod 502 passively retracts and changes its angle as the connecting ring 503 rises and the blade holder 5 moves inward. The cutting edge of the ring scraper 501 presses against the surface of the heating coil 4 during the movement of the blade holder 5, removing the scale on the surface of the heating coil 4. The connecting ring 503 moves upward until it reaches the limit position detected by the integrated sensor 505. The integrated sensor 505 cuts off the power to the motor 507 and reverses the power supply to the motor 507, causing the motor 507 to reverse. The motor 507 drives the telescopic rod 502 through the lead screw 504 to reset the blade holder 5, completing one scale cleaning cycle.
