Description

Technical Field

[0001] This utility model relates to the field of temperature control device technology, and in particular to a low ammonia consumption temperature control device for circulating water. Background Technology

[0002] An ammonia refrigeration unit uses ammonia as its refrigerant. It operates based on the vapor compression refrigeration cycle principle, where ammonia undergoes four processes: compression, condensation, expansion, and evaporation. Specifically, ammonia is first compressed into a high-pressure gas by the compressor, increasing its temperature and pressure. It then enters the condenser, where it exchanges heat with the cooling medium, cooling into a high-pressure liquid. Next, it passes through a throttling valve or expansion valve, causing a rapid pressure drop to become low-temperature, low-pressure ammonia. Finally, it exchanges heat with the object being cooled in the heat exchanger, absorbing heat and evaporating into a low-pressure gas, which is then drawn back into the compressor, repeating the cycle to achieve refrigeration. In practical applications, when using an ammonia refrigeration unit to regulate the temperature of circulating water, the circulating water and the refrigeration end of the ammonia refrigeration unit are connected to a heat exchanger for heat exchange, thereby lowering the temperature of the circulating water.

[0003] The above-mentioned and existing technologies have the following drawbacks: During the process of using an ammonia chiller to regulate circulating water, the circulating water will contain impurities due to its long-term continuous operation. These impurities will adhere to the inner wall of the heat exchanger after entering it, resulting in a decrease in the heat exchange efficiency of the heat exchanger. In order to achieve the required temperature control performance, the power of the ammonia chiller needs to be increased, thereby increasing the consumption of ammonia.

[0004] Therefore, a low ammonia consumption temperature control device for circulating water is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that when using an ammonia chiller to regulate circulating water, impurities enter the heat exchanger and adhere to the inner wall of the heat exchanger, causing a decrease in the heat exchange efficiency and requiring an increase in the power of the ammonia chiller. Therefore, this invention proposes a low ammonia consumption temperature control device for circulating water.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a circulating water low ammonia consumption temperature control device, comprising a base, an ammonia chiller and a heat exchange tube fixedly mounted on the upper surface of the base, a heat conduction pipe fixedly installed inside the heat exchange tube, the ammonia chiller being fixedly connected to the heat conduction pipe, a drain pipe and a filter frame being fixedly connected to the outer circumference of the heat exchange tube, a water inlet pipe being fixedly connected to the upper surface of the filter frame, a plurality of fixing plates fixedly mounted on the inner wall of the filter frame, a sliding rod slidingly passing through the fixing plate, a filter plate fixedly mounted on the upper end of the sliding rod, the filter plate being slidably connected to the filter frame, and a baffle fixedly mounted on the inner wall of the filter frame, the baffle being slidably connected to the filter plate.

[0007] The effect achieved by the above components is as follows: by setting up components such as filter frames, filter plates and baffles, when the temperature of the circulating water is adjusted, the filter plates will filter the circulating water to prevent impurities in the circulating water from entering the heat exchange tubes, thereby ensuring that the heat exchange tubes can exchange heat normally and thus reducing the consumption of ammonia.

[0008] Preferably, a rotating frame that abuts against the surface of a baffle is rotatably connected inside the filter frame, a rotating shaft is rotatably connected inside the filter frame, a cam is fixedly mounted on the outer circumference of the rotating shaft, a motor is fixedly mounted on the outer wall of the filter frame, the output end of the motor is fixedly connected to the rotating shaft, and an extension rod is fixedly mounted on the filter plate relative to the position of the cam.

[0009] The effect achieved by the above components is as follows: when the motor is turned on, the output end of the motor rotates, which drives the shaft to rotate. The shaft drives the cam to rotate. The cam first squeezes the extension rod, which moves upward and drives the filter plate to move synchronously. When the cam rotates to a certain angle, it will disengage from the extension rod, and the filter plate will move downward. Therefore, as the motor continues to run, the filter plate will continue to shake, thereby shaking off the impurities remaining on the upper surface of the filter plate.

[0010] Preferably, a spring is fitted on the outer circumference of the slide rod, and the two ends of the spring are fixedly connected to the fixing plate and the filter plate, respectively.

[0011] The effect achieved by the above components is that when the spring contracts, the filter plate will move downwards quickly with the help of the spring's elastic force.

[0012] Preferably, the filter frame has a drain outlet at a position relative to the rotating frame.

[0013] The effect achieved by the above components is that when the rotating frame is aligned with the drain outlet, the impurities inside the rotating frame will fall out through the drain outlet.

[0014] Preferably, the filter frame is fixedly fitted with a guide plate relative to the position of the drain outlet.

[0015] The effect achieved by the above components is that the guide plate can guide impurities, thereby making it easier for staff to collect them.

[0016] Preferably, a limiting post is rotatably connected inside the filter frame, the limiting post is fixedly connected to the rotating frame, a protrusion is fixedly mounted on the outer wall of the filter frame, a limiting rod slides through the protrusion, and the limiting rod passes through the limiting post.

[0017] The effect achieved by the above components is as follows: when the limiting post is rotated to a suitable position, the limiting rod is inserted into the limiting post to restrict the position of the limiting post, thereby restricting the position of the rotating frame.

[0018] Preferably, a magnetic block is fixedly mounted on the upper end of the limiting rod, and the protrusion is made of iron.

[0019] The effect achieved by the above components is that when the magnetic block comes into contact with the protrusion, the magnetic block will be attracted to the surface of the protrusion, thereby preventing the limiting rod from coming out of the limiting post.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, by setting up components such as a filter frame, filter plate, and baffle, the filter plate will filter the circulating water when the temperature of the circulating water is adjusted, preventing impurities in the circulating water from entering the heat exchange tube, thereby ensuring that the heat exchange tube can exchange heat normally and thus reducing the consumption of ammonia.

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] like Figures 1-5 As shown, this utility model provides a low ammonia consumption temperature control device for circulating water, including a base 1. An ammonia chiller 2 and a heat exchange tube 3 are fixedly mounted on the upper surface of the base 1. A heat conduction tube 4 is fixedly installed inside the heat exchange tube 3. The ammonia chiller 2 is fixedly connected to the heat conduction tube 4. A drain pipe 5 and a filter frame 6 are fixedly connected to the outer circumference of the heat exchange tube 3. A water inlet pipe 7 is fixedly connected to the upper surface of the filter frame 6. Several fixing plates 8 are fixedly mounted on the inner wall of the filter frame 6. A sliding rod 9 slides through the fixing plate 8. A filter plate 10 is fixedly mounted on the upper end of the filter frame 6, and the filter plate 10 is slidably connected to the filter frame 6. A baffle 11 is fixedly mounted on the inner wall of the filter frame 6, and the baffle 11 is slidably connected to the filter plate 10. By setting up components such as the filter frame 6, filter plate 10, and baffle 11, when the temperature of the circulating water is adjusted, the filter plate 10 will filter the circulating water to prevent impurities in the circulating water from entering the heat exchange tube 3, thereby ensuring that the heat exchange tube 3 can exchange heat normally and reducing the consumption of ammonia. The filter frame 6 is rotatably connected to... A rotating frame 12 rests against the surface of the baffle 11. A rotating shaft 13 is rotatably connected inside the filter frame 6. A cam 14 is fixedly mounted on the outer circumference of the rotating shaft 13. A motor 15 is fixedly mounted on the outer wall of the filter frame 6. The output end of the motor 15 is fixedly connected to the rotating shaft 13. An extension rod 16 is fixedly mounted on the filter plate 10 relative to the cam 14. When the motor 15 is turned on, the output end of the motor 15 rotates, causing the rotating shaft 13 to rotate. The rotating shaft 13 then rotates the cam 14, which first presses against the extension rod 16, extending... The extension rod 16 will move upward and drive the filter plate 10 to move synchronously. When the cam 14 rotates to a certain angle, it will disengage from the extension rod 16, and the filter plate 10 will move downward. Therefore, as the motor 15 continues to run, the filter plate 10 will continue to shake, thereby shaking off the impurities remaining on the upper surface of the filter plate 10. The outer circumference of the slide rod 9 is fitted with a spring 17. The two ends of the spring 17 are fixedly connected to the fixed plate 8 and the filter plate 10 respectively. When the spring 17 contracts, the filter plate 10 will move downward quickly with the help of the elastic force of the spring 17.

[0031] A drain port 18 is provided in the filter frame 6 relative to the rotating frame 12. When the rotating frame 12 is aligned with the drain port 18, impurities inside the rotating frame 12 will fall through the drain port 18. A guide plate 19 is fixedly installed in the filter frame 6 relative to the drain port 18. The guide plate 19 can guide the impurities, thereby facilitating the collection of impurities by the staff. A limiting post 20 is rotatably connected inside the filter frame 6. The limiting post 20 is fixedly connected to the rotating frame 12. A protrusion 21 is fixedly installed on the outer wall of the filter frame 6. The protrusion 21 slides inside. The limit rod 22 passes through the limit post 20. When the limit post 20 is rotated to a suitable position, the limit rod 22 is inserted into the limit post 20 to limit the position of the limit post 20, thereby limiting the position of the rotating frame 12. A magnetic block 23 is fixedly installed at the upper end of the limit rod 22. The protrusion 21 is made of iron. When the magnetic block 23 contacts the protrusion 21, the magnetic block 23 will be attracted to the surface of the protrusion 21, thereby preventing the limit rod 22 from coming out of the limit post 20.

[0032] The overall working principle is as follows: When adjusting the temperature of the circulating water, the circulating water is introduced into the inlet pipe 7. After entering the filter frame 6, the circulating water flows onto the surface of the filter plate 10. The filter plate 10 filters the circulating water, preventing impurities in the circulating water from entering the heat exchange tube 3, thus ensuring that the heat exchange tube 3 can exchange heat normally and reducing ammonia consumption. At this time, the impurities will remain on the upper surface of the filter plate 10. When it is necessary to clean the impurities, the motor 15 is turned on. The output end of the motor 15 rotates, which drives the rotating shaft 13 to rotate. The rotating shaft 13 will carry... When the cam 14 rotates, it first presses against the extension rod 16, causing the extension rod 16 to move upward and simultaneously move the filter plate 10. The movement of the filter plate 10 stretches the spring 17. After the cam 14 rotates a certain angle, it disengages from the extension rod 16, at which point the spring 17 contracts. The filter plate 10 then moves rapidly downward with the help of the spring 17. Therefore, as the motor 15 continues to run, the filter plate 10 continuously vibrates, shaking off impurities remaining on its surface. These impurities fall onto the inner wall of the rotating frame 12 for temporary storage, and are then discharged later. When removing impurities from the rotating frame 12, pull the magnetic block 23 upwards to remove the limiting rod 22 from the limiting post 20. Then rotate the limiting post 20, which will cause the rotating frame 12 to rotate. When the rotating frame 12 is aligned with the drain outlet 18, the impurities in the rotating frame 12 will fall into the guide plate 19 through the drain outlet 18. The guide plate 19 can guide the impurities, making it convenient for workers to collect them. Then rotate the limiting post 20 in the opposite direction. When the limiting post 20 is rotated to the appropriate position, insert the limiting rod 22 into the limiting post 20 to limit the movement. The position of the column 20 is restricted, thereby restricting the position of the rotating frame 12. When the magnetic block 23 contacts the protrusion 21, the magnetic block 23 will be attracted to the surface of the protrusion 21, thereby preventing the limiting rod 22 from coming out of the limiting column 20. After being filtered by the filter plate 10, the circulating water will flow into the heat exchange tube 3. At this time, the ammonia refrigeration machine 2 is turned on, and the ammonia refrigeration machine 2 will reduce the heat of the heat conduction tube 4, thereby allowing the heat conduction tube 4 to absorb the heat of the circulating water, thereby cooling the circulating water and controlling the temperature of the circulating water. The cooled circulating water will flow out through the drain pipe 5.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
