Description
Technical Field
[0001] This utility model relates to the field of water circulator technology, and in particular to a water circulator for aluminum bar heaters. Background Technology
[0002] In industrial production, aluminum bar heaters are commonly used heating equipment and require stable heat transfer to provide heat. The water circulator used for aluminum bar heaters is a key supporting device. Its main function is to transfer the heat generated by the aluminum bar heater to the heat-using end through water circulation, while removing excess heat from the heater to avoid local overheating. In scenarios such as machining and workshop temperature control, aluminum bar heaters need to continuously output heat, and the supply of heating water depends entirely on the water circulator.
[0003] The existing water circulator for aluminum bar heaters mainly consists of a water storage tank, a conventional water pump, and a water delivery pipe. The water storage tank stores cold water to be heated and is the basic water source for water circulation. The water pump is installed on the water storage tank. After being powered on, the impeller rotates to generate power, pumping the cold water in the water storage tank into the water delivery pipe, and then delivering it to the inlet of the aluminum bar heater. After the aluminum bar heater heats the incoming cold water, the resulting heated water flow is sent back to the water circulator through another set of water delivery pipes. The outlet pipe of the water circulator then delivers the heated water flow to the heat-using end.
[0004] Existing water circulators used for aluminum bar heaters suffer from the problem of unstable hot water temperature due to backflow of cold water. When the water pump pressure fluctuates, the heating end equipment suddenly stops causing a drop in pipeline pressure, or the system experiences a temporary power outage, unused low-temperature water in the downstream heating end pipeline, cold water in the storage tank, and even cold water seeping in from the outside will flow back to the hot water outlet of the aluminum bar heater through the water supply pipe, mixing with the already heated hot water inside the heater. This temperature instability reduces the heating effect of the aluminum bar heater. If used for environmental temperature control, fluctuating workshop temperatures will affect production. At the same time, in order to reheat the cooled water to the target temperature, the heater needs to operate at high power frequently, which not only consumes electricity but also accelerates the aging of internal components and increases the risk of equipment failure. Therefore, a water circulator for aluminum bar heaters is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a water circulator for aluminum bar heaters, which aims to improve the problem in the prior art where the mixing of cold water and hot water in the heater directly leads to the dilution of hot water and damages the temperature stability of the hot water at the outlet.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A water circulator for an aluminum strip heater includes a circulator body, an outlet pipe fixedly connected to the side wall of the circulator body, an inlet pipe fixedly connected to the side wall of the circulator body, a heater body fixedly connected to one end of the outlet pipe and one end of the inlet pipe, a water pump fixedly connected to the side wall of the circulator body, an outlet pipe fixedly connected to the output end of the water pump, a check valve assembly installed inside the outlet pipe, and a filter assembly installed inside the inlet pipe. The check valve assembly includes a baffle post, the outer wall of which is disposed inside the second water outlet pipe. A fixing frame is fixedly connected to the inner wall of the second water outlet pipe. The outer wall of the baffle post is slidably connected to the inner wall of the fixing frame. A reset assembly is provided on the outer wall of the fixing frame. A water outlet groove is opened inside the baffle post. A retaining ring is fixedly connected to the outer wall of the baffle post. A sealing ring is fixedly connected to the outer wall of the retaining ring.
[0007] As a further description of the above technical solution: The reset assembly includes a sliding rod, one end of which is fixedly connected to the outer wall of the fixed frame, the inner wall of the stop post is slidably connected to the outer wall of the sliding rod, and a spring is sleeved on the outer wall of the sliding rod, one end of which is fixedly connected to the outer wall of the stop post, and the other end of which is fixedly connected to the outer wall of the fixed frame.
[0008] As a further description of the above technical solution: The filter assembly includes a filter screen, the outer wall of which is disposed inside the second water inlet pipe.
[0009] As a further description of the above technical solution: The water inlet pipe has a sliding groove inside, and the filter screen is fixedly connected to a sealing ring.
[0010] As a further description of the above technical solution: The filter screen has a slot inside, and a slider is fixedly connected to the outer wall of the filter screen.
[0011] As a further description of the above technical solution: The outer wall of the slider is slidably connected to the inner wall of the sliding groove, and the outer wall of the water inlet pipe is fixedly connected to a fixing block.
[0012] As a further description of the above technical solution: The inner wall of the fixed block is slidably connected to a locking block, and the outer wall of the locking block is slidably connected to the inner wall of the second water inlet pipe.
[0013] As a further description of the above technical solution: The outer wall of the card block is slidably connected to the inner wall of the card slot, and a sliding column is fixedly connected to the top of the card block.
[0014] As a further description of the above technical solution: The outer wall of the sliding column is slidably connected to the inner wall of the fixed block, and a pull rod is fixedly connected to the top of the sliding column.
[0015] As a further description of the above technical solution: A second spring is fitted on the outer wall of the sliding column. One end of the second spring is fixedly connected to the inner wall of the fixed block, and the other end of the second spring is fixedly connected to the top of the locking block.
[0016] This utility model has the following beneficial effects: In this invention, the retaining ring slides against the inner wall of the fixed frame via the baffle post, and then the sealing ring is brought into contact with the outer wall of the fixed frame by the retaining ring. This achieves the effect of preventing cold water backflow, avoiding the backflow of cold water, unheated low-temperature circulating water, or residual cold water from the external system back into the outlet and mixing with the hot water in the heater. Backflow would directly dilute the hot water and disrupt the temperature stability of the hot water at the outlet, thus ensuring that the water output from the outlet is always high-temperature water continuously heated by the heater, guaranteeing a stable hot water temperature at the outlet and improving the accuracy of heat use.
[0017] In this invention, a filter screen drives a slider to slide on the inner wall of a sliding groove. The filter screen then intercepts impurities in the water flow, achieving the effect of filtering impurities in the water flow. This prevents circulating water from carrying a large amount of dust, impurities, and other pollutants during long-term use. These substances are prone to adhering to the inner wall of the pipe, causing the inner diameter of the pipe to decrease or even become blocked. This invention prevents them from accumulating in the pipe and ensures smooth water circulation. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0021] Reference Figures 1-4 This utility model provides an embodiment of a water circulator for an aluminum strip heater, comprising a circulator body 1. The circulator body 1 provides a stable installation reference for the entire water circulation system, ensuring that the components maintain their relative positions during operation and guaranteeing long-term stable operation of the system. A water outlet pipe 2 is fixedly connected to the side wall of the circulator body 1, connecting the heater body 4 and the circulator body 1, and transporting hot water heated inside the heater body 4 to the circulator body 1. A water inlet pipe 3 is fixedly connected to the side wall of the circulator body 1, transporting cold water or water to be heated from the circulator body 1 to the heater body 4, providing a continuous heating water source for the heater body 4 and ensuring uninterrupted heating. The water outlet pipe... Heater body 4 is fixedly connected to one end of pipe 2 and one end of inlet pipe 3. Water pump 5 is fixedly connected to the side wall of circulator body 1. Water pump 5 provides power for transporting hot water in circulator body 1, driving hot water to flow from circulator body 1 to outlet pipe 6, ensuring that hot water can overcome pipeline resistance and be transported to external equipment. The output end of water pump 5 is fixedly connected to outlet pipe 6, which transports the hot water that flows back from circulator body 1 through outlet pipe 2 to external equipment, realizing the final utilization of hot water. A check valve component is installed inside outlet pipe 6. Inlet pipe 7 is fixedly connected to the side wall of circulator body 1. Inlet pipe 7 introduces external cold water into circulator body 1 to replenish the water source of the system and maintain the balance of circulating water volume. A filter component is installed inside inlet pipe 7. The check valve assembly includes a baffle 10, which blocks the internal passage of the outlet pipe 6 when the water flow is reversed, preventing the water from flowing backward. The outer wall of the baffle 10 is located inside the outlet pipe 6, and a fixing frame 8 is fixedly connected to the inner wall of the outlet pipe 6. When the forward water flow pressure is greater than the elastic force of the spring 11, the baffle 10 slides away from the fixing frame 8, opening the outlet passage. When the forward water flow pressure disappears, the baffle 10 slides closer to the fixing frame 8, closing the outlet passage, thus achieving flexible control of the opening and closing of the passage. The outer wall of the baffle 10 is slidably connected to the inner wall of the fixing frame 8, and a reset component is provided on the outer wall of the fixing frame 8. A water outlet groove 12 is provided inside the baffle 10. The water outlet groove 12 is used to allow hot water to pass smoothly when the forward water flow pressure pushes the baffle 10 to move. The hot water is then transported to external equipment through the outlet pipe 6. The outer wall of the baffle 10 is fixed. A retaining ring 13 is connected, and a sealing ring 14 is fixedly connected to the outer wall of the retaining ring 13. The sealing ring 14 fills the gap between the retaining ring 13 and the fixing frame 8 to prevent water leakage and enhance the reverse sealing effect. The reset component includes a sliding rod 9, which slides in conjunction with the baffle 10 to ensure that the baffle 10 does not deviate when moving and that the baffle 10 can completely cover the aperture of the fixing frame 8. One end of the sliding rod 9 is fixedly connected to the outer wall of the fixing frame 8, and the inner wall of the baffle 10 is slidably connected to the outer wall of the sliding rod 9. A spring 11 is sleeved on the outer wall of the sliding rod 9. One end of the spring 11 is fixedly connected to the outer wall of the baffle 10, and the other end of the spring 11 is fixedly connected to the outer wall of the fixing frame 8. When the forward water flow pushes the baffle 10, the spring 11 is compressed. When the water pressure disappears, the spring 11 returns to its original shape and pushes the baffle 10 to reset, closing the channel and achieving the effect of preventing reverse backflow.
[0022] Reference Figure 5 and Figure 6The filter assembly includes a filter screen 15, which filters impurities in the inlet pipe 7, ensuring the cleanliness of the cold water entering the circulator body 1 and achieving the effect of purifying the water entering the circulation system. The outer wall of the filter screen 15 is set inside the inlet pipe 7, and a sliding groove 16 is provided inside the inlet pipe 7. The sliding groove 16 provides a matching sliding track for the slider 19, clearly defining the installation direction and position of the filter screen 15, and achieving the effect of ensuring the precise installation of the filter screen 15. A sealing ring 17 is fixedly connected to the outer wall of the filter screen 15. The sealing ring 17 fits tightly against the inner wall of the inlet pipe 7, filling the gap between the filter screen 15 and the inlet pipe 7, thereby preventing unfiltered water from flowing into the circulator body 1 through the gap. A slot 18 is provided inside the filter screen 15. The locking block 21 engages with the filter screen 15 to secure it and prevent it from moving under the impact of water flow. A slider 19 is fixedly connected to the outer wall of the filter screen 15. The slider 19 engages with the sliding groove 16. During installation, the slider 19 is inserted into the sliding groove 16 to secure the filter screen 15. During disassembly, it is pulled out along the sliding groove 16, allowing for quick installation and removal of the filter screen 15 and facilitating cleaning or replacement. The outer wall of the slider 19 is slidably connected to the inner wall of the sliding groove 16. A fixing block 20 is fixedly connected to the outer wall of the water inlet pipe 27. The fixing block 20 provides installation space and support for the locking block 21, sliding column 22, and spring 24, achieving the effect of fixing the filter assembly structure. A locking block is slidably connected to the inner wall of the fixing block 20. 21. The outer wall of the locking block 21 is slidably connected to the inner wall of the water inlet pipe 2 7, and the outer wall of the locking block 21 is slidably connected to the inner wall of the slot 18. The locking block 21 engages with the slot 18. When the locking block 21 is inserted into the slot 18, it fixes the filter screen 15 by limiting its movement. When the locking block 21 is pulled out of the slot 18, it releases the fixation of the filter screen 15, achieving the effect of quickly fixing and removing the filter screen 15. A sliding post 22 is fixedly connected to the top of the locking block 21. The sliding post 22 connects the locking block 21 and the pull rod 23, transmitting the pulling force of the pull rod 23 to the locking block 21, achieving the effect of controlling the movement of the locking block 21 through the pull rod 23. The outer wall of the sliding post 22 is slidably connected to the inner wall of the fixing block 20. The fixing block 20 provides guidance for the movement of the sliding post 22 and the locking block 21, restricting them to only move along... The vertical movement prevents the locking block 21 from shifting and failing to engage with the slot 18. A pull rod 23 is fixedly connected to the top of the sliding column 22, and a spring 24 is sleeved on the outer wall of the sliding column 22. When the pull rod 23 is not pulled, the spring 24 provides a downward elastic force to the locking block 21, pushing the locking block 21 tightly into the slot 18, thus maintaining the filter screen 15 in a fixed state. One end of the spring 24 is fixedly connected to the inner wall of the fixing block 20, and the other end is fixedly connected to the top of the locking block 21. When the pull rod 23 is pulled, the sliding column 22 drives the locking block 21 to move upward, and the spring 24 is compressed and stores potential energy. After the pull rod 23 is released, the spring 24 releases potential energy and pushes the locking block 21 downward, re-engaging it into the slot 18, thus achieving an automatic reset and fixation effect.
[0023] Working principle: When water pump 5 starts, hot water from inside the circulator body 1 is sent out through outlet pipe 2 6. The pressure generated by water pump 5 causes baffle 10 to slide on the inner wall of fixed frame 8. Then, baffle 10 slides on the outer wall of sliding rod 9, compressing spring 11. Next, the sliding of baffle 10 causes retaining ring 13 to move, and then the movement of retaining ring 13 causes sealing ring 14 to move. When retaining ring 13 and sealing ring 14 move away from the outer wall of fixed frame 8, they are in the open state, and water flows out through outlet trough 12. When water pump 5 is turned off, the spring 11 first causes the stop column 10 to reset, and then the stop column 10 resets the retaining ring 13. Next, the retaining ring 13 resets the sealing ring 14 to fit against the outer wall of the fixing frame 8. When the outer wall of the sealing ring 14 fits against the outer wall of the fixing frame 8, it is in a closed state, which prevents cold water, unheated low-temperature circulating water or residual cold water from the downstream pipeline from flowing back into the outlet and mixing with the hot water in the heater. Backflow will directly dilute the hot water and destroy the temperature stability of the hot water at the outlet.
[0024] First, pull rod 23. Pulling rod 23 causes sliding column 22 to slide on the inner wall of fixed block 20. Then, the sliding column 22 moves the locking block 21, which compresses spring 24. The slider 19 on the outer wall of filter screen 15 is then inserted into the inner wall of sliding groove 16. Once filter screen 15 is in place, release pull rod 23. The rebound of spring 24 moves locking block 21 into slot 18, completing the installation of filter screen 15. Finally, filter screen 15 filters the water entering the circulator body 1. Impurities are filtered out. When the filter screen 15 needs to be cleaned and replaced, first pull the lever 23. Pulling the lever 23 will cause the sliding column 22 to slide on the inner wall of the fixed block 20. Then, the sliding column 22 will cause the locking block 21 to move. When the locking block 21 moves out of the slot 18, it will release the fixing of the filter screen 15. Then, pull the filter screen 15 to complete the disassembly. This avoids the circulating water from carrying a large amount of dust, impurities and other pollutants during long-term use. These substances are easy to adhere to the inner wall of the pipe, causing the inner diameter of the pipe to become smaller or even blocked.
