Abstract
Description
Technical Field
[0001] This utility model relates to the field of chiller technology, and in particular to an energy-saving chiller unit for refrigeration equipment. Background Technology
[0002] A chiller unit comprises four main components: a compressor, an evaporator, a condenser, a filter, and a throttling valve. These components enable the unit to provide cooling and heating. The compressor compresses the refrigerant into a high-temperature, high-pressure vapor state, which then enters the condenser, releasing heat and condensing into a liquid state. The liquid refrigerant passes through a filter to remove impurities. Subsequently, the refrigerant is throttled by the throttling valve and flows into the evaporator, where it is transformed from a high-pressure, medium-temperature liquid refrigerant into a low-pressure, medium-temperature vapor state before returning to the compressor.
[0003] After the condenser converts the high-pressure, high-temperature gas into a high-pressure, low-temperature liquid, the liquid enters the throttle valve. During this process, the filter removes impurities from the liquid. After prolonged use, the filter screen needs to be cleaned. Currently, the filter screen is cleaned manually, which is time-consuming and difficult, thus reducing the efficiency of the workers. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides an energy-saving chiller unit for refrigeration equipment.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an energy-saving chiller unit for refrigeration equipment, comprising an internally hollow filter cylinder, a filter element fixedly disposed on the inner bottom wall of the filter cylinder, a filter hole penetrating through the outer wall of the filter element, an inlet pipe installed on the outer wall of the filter cylinder, an outlet pipe installed on the bottom surface of the filter cylinder, the axis of the outlet pipe coinciding with the axis of the filter cylinder, and a cleaning device for cleaning the filter element disposed inside the filter cylinder.
[0006] By adopting the above technical solution, after the condenser converts the gas into liquid, the liquid flows into the filter cartridge through the inlet pipe. Subsequently, it flows into the throttling valve through the outlet pipe. During this process, the filter holes on the surface of the filter element filter out impurities in the water, causing the impurities to adhere to the surface of the filter element or fall onto the inner bottom wall of the filter cartridge. Later, when the filter element needs cleaning, the cleaning device is activated to clean it. This process eliminates the need for manual cleaning, reducing cleaning time and difficulty, and thus improving worker efficiency.
[0007] Furthermore, the cleaning device includes a motor fixedly mounted on the upper surface of the filter cylinder, a circular plate fixedly mounted on the end of the motor output shaft, and a cleaning component fixedly mounted on the bottom surface of the circular plate. The motor output shaft passes through the filter cylinder and extends into the filter cylinder, where it is fixed to the circular plate. The bottom surface of the circular plate abuts against the upper surface of the filter component.
[0008] By adopting the above technical solution, when the staff needs to clean the filter element, the staff needs to start the motor, which will cause the output shaft of the motor to rotate. This will cause the circular plate to rotate under the action of the motor output shaft, and in turn, the cleaning element will rotate under the action of the circular plate. This will cause the cleaning element to clean the filter element, thereby scraping off the impurities on the surface of the filter element and causing the impurities to fall onto the inner bottom wall of the filter cylinder. In this process, the cleaning device does not require the staff to manually clean the filter element, thereby reducing the cleaning time and difficulty for the staff and improving the work efficiency of the staff.
[0009] Furthermore, a drain port is provided through the inner bottom wall of the filter cylinder, a drain pipe is installed in the drain port, and a control valve for controlling the opening and closing of the drain pipe is provided on the drain pipe. A cleaning plate is fixedly provided on the bottom surface of the cleaning component, and the bottom surface of the cleaning plate abuts against the inner bottom wall of the filter cylinder.
[0010] By adopting the above technical solution, when the cleaning component rotates under the action of the circular plate, the cleaning plate rotates under the action of the cleaning component, thereby scraping away impurities on the bottom wall of the filter cylinder. When the impurities pass the upper end of the drain pipe, they are discharged out of the filter cylinder through the drain pipe, thus reducing the difficulty for workers to collect impurities and reducing the workload of the workers. In addition, the control valve can control the opening and closing of the drain pipe, reducing the probability of water flowing out along the drain pipe when the filter cylinder is working.
[0011] Furthermore, two sliding holes are symmetrically formed on the side wall of the cleaning component near the filter element. A sliding rod is slidably arranged in the sliding hole, and a scraper is fixedly arranged on the side wall of the sliding rod. The side wall of the scraper away from the sliding rod abuts against the outer wall of the filter element.
[0012] Furthermore, a retaining spring is fitted on the outer wall of the slide rod, one end of the retaining spring abutting against the side wall of the cleaning component, and the other end of the retaining spring abutting against the side wall of the scraper.
[0013] By adopting the above technical solution, when the cleaning component cleans the filter component, the slide bar slides under the action of the clamping spring, which in turn causes the scraper to move under the action of the slide bar. As a result, the scraper presses against the outer wall of the filter component under the action of the clamping spring and the slide bar, thereby improving the cleaning effect.
[0014] Furthermore, a limiting hole is formed on the inner wall of the sliding hole, and a limiting plate is slidably disposed in the limiting hole. The limiting plate is fixed to the sliding rod, and the diameter of the limiting hole is larger than the diameter of the sliding hole.
[0015] By adopting the above technical solution, when the slide bar slides, the limiting plate slides under the action of the slide bar. During this process, the limiting plate reduces the probability of the slide bar and the sliding hole separating from each other, thereby improving the stability of the device.
[0016] Furthermore, the lower part of the filter element does not have filter holes.
[0017] By adopting the above technical solution, the cleaning plate cannot clean the impurities on the surface of the filter element. Therefore, no filter holes are opened in the lower part of the filter element.
[0018] Furthermore, the surface of the filter element is coated with a sound-absorbing coating.
[0019] By adopting the above technical solution, the sound-absorbing material reduces the probability of excessive noise from the filter element when the scraper cleans it.
[0020] In summary, this utility model has the following beneficial effects:
[0021] 1. In this application, after the condenser converts the gas into liquid, the liquid flows into the filter cartridge through the inlet pipe. Subsequently, it flows into the throttle valve through the outlet pipe. During this process, the filter holes on the surface of the filter element filter out impurities in the water, causing the impurities to adhere to the surface of the filter element or fall onto the inner bottom wall of the filter cartridge. Later, when the filter element needs cleaning, the worker needs to activate the cleaning device to clean it. In this process, the cleaning device eliminates the need for manual cleaning, thus reducing cleaning time and difficulty, and improving worker efficiency.
[0022] 2. In this application, when the staff needs to clean the filter element, the staff needs to start the motor, which will cause the output shaft of the motor to rotate, thereby causing the circular plate to rotate under the action of the motor output shaft, and then causing the cleaning element to rotate under the action of the circular plate, thereby cleaning the filter element, scraping off the impurities on the surface of the filter element, and causing the impurities to fall onto the inner bottom wall of the filter cylinder. In this process, the cleaning device does not require the staff to manually clean the filter element, thereby reducing the cleaning time and difficulty for the staff, and thus improving the work efficiency of the staff.
[0023] 3. In this application, when the cleaning component rotates under the action of the circular plate, the cleaning plate rotates under the action of the cleaning component, thereby scraping away impurities on the bottom wall of the filter cylinder. When the impurities pass the upper end of the drain pipe, they are discharged out of the filter cylinder through the drain pipe, thus reducing the difficulty for workers to collect impurities and reducing the workload of the workers. In addition, the control valve can control the opening and closing of the drain pipe, reducing the probability of water flowing out along the drain pipe when the filter cylinder is working.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0030] like Figure 1-4 As shown in the illustration, this application discloses an energy-saving chiller unit for refrigeration equipment, including a filter cylinder 1, a filter element 11, an inlet pipe 12, an outlet pipe 13, a cleaning device 2, a drain pipe 31, a cleaning plate 32, a sliding rod 41, a scraper 42, a retaining spring 5, and a limiting plate 61. The filter cylinder 1 is a hollow cylindrical structure. The filter element 11 is fixedly installed on the inner bottom wall of the filter cylinder 1, and a filter hole 14 is formed through the outer wall of the filter element 11. The inlet pipe 12 is installed on the outer wall of the filter cylinder 1, and the outlet pipe 13 is installed on the bottom surface of the filter cylinder 1, with the axis of the outlet pipe 13 coinciding with the axis of the filter cylinder 1.
[0031] After the condenser converts the gas into liquid, the liquid flows into the filter cartridge 1 through the inlet pipe 12. Then, it flows through the outlet pipe 13 to the throttle valve. During this process, the filter holes 14 on the surface of the filter element 11 filter impurities in the water, causing them to adhere to the surface of the filter element 11 or fall onto the inner bottom wall of the filter cartridge 1. Subsequently, when the filter element 11 needs cleaning, the cleaning device 2 is activated to clean it. This process eliminates the need for manual cleaning of the filter element 11, reducing cleaning time and difficulty, and thus improving work efficiency.
[0032] A cleaning device 2 is installed inside the filter cylinder 1 for cleaning the filter element 11. The cleaning device 2 includes a motor 21, a circular plate 22, and a cleaning component 23. The motor 21 is fixedly installed on the upper surface of the filter cylinder 1, and its output shaft axis is vertical. The circular plate 22 is fixedly installed at the end of the output shaft of the motor 21, and its axis coincides with the axis of the output shaft of the motor 21. The output shaft of the motor 21 passes through the filter cylinder 1 and extends into the filter cylinder 1, where it is fixed to the circular plate 22. The bottom surface of the circular plate 22 abuts against the upper surface of the filter element 11, and the cleaning component 23 is fixedly installed on the bottom surface of the circular plate 22.
[0033] When the staff needs to clean the filter element 11, the staff needs to start the motor 21, which will cause the output shaft of the motor 21 to rotate, thereby causing the circular plate 22 to rotate under the action of the output shaft of the motor 21. This will cause the cleaning element 23 to rotate under the action of the circular plate 22, thereby cleaning the filter element 11 and scraping off the impurities on the surface of the filter element 11. The impurities will fall onto the inner bottom wall of the filter cylinder 1. In this process, the cleaning device 2 does not require the staff to manually clean the filter element 11, thereby reducing the cleaning time and difficulty for the staff and improving the work efficiency of the staff.
[0034] A drain port 3 is provided through the inner bottom wall of the filter cylinder 1. A drain pipe 31 is installed inside the drain port 3. A control valve (not shown in the figure) is provided on the drain pipe 31 to control the opening and closing of the drain pipe 31. A cleaning plate 32 is fixedly installed on the bottom surface of the cleaning component 23, and the bottom surface of the cleaning plate 32 abuts against the inner bottom wall of the filter cylinder 1.
[0035] When the cleaning component 23 rotates under the action of the circular plate 22, the cleaning plate 32 rotates under the action of the cleaning component 23, thereby scraping away impurities on the bottom wall of the filter cylinder 1. When the impurities pass the upper end of the drain pipe 31, they are discharged from the filter cylinder 1 through the drain pipe 31, thus reducing the difficulty for workers to collect impurities and reducing the workload of the workers. In addition, the control valve can control the opening and closing of the drain pipe 31, reducing the probability of water flowing out along the drain pipe 31 when the filter cylinder 1 is working.
[0036] Two sliding holes 4 are symmetrically formed on the side wall of the cleaning component 23 near the filter component 11. The sliding rod 41 is a round rod structure with its axis horizontal, and the sliding rod 41 is slidably disposed in the sliding hole 4. The scraper 42 is fixedly disposed on the side wall of the sliding rod 41, and the side wall of the scraper 42 away from the sliding rod 41 abuts against the outer wall of the filter component 11.
[0037] The clamping spring 5 is sleeved on the outer wall of the slide rod 41. One end of the clamping spring 5 abuts against the side wall of the cleaning component 23, and the other end of the clamping spring 5 abuts against the side wall of the scraper 42.
[0038] When the cleaning component 23 cleans the filter component 11, the slide rod 41 slides under the action of the clamping spring 5, which in turn causes the scraper 42 to move under the action of the slide rod 41. As a result, the scraper 42 presses against the outer wall of the filter component 11 under the action of the clamping spring 5 and the slide rod 41, thereby improving the cleaning effect.
[0039] A limiting hole 6 is provided on the inner wall of the sliding hole 4. The limiting plate 61 is a circular plate 22 structure, and its axis coincides with the axis of the sliding rod 41. The sliding plate is slidably set in the sliding hole 4. The limiting plate 61 and the sliding rod 41 are fixed to each other, and the diameter of the limiting hole 6 is larger than the diameter of the sliding hole 4.
[0040] When the slide bar 41 slides, the limiting plate 61 slides under the action of the slide bar 41. During this process, the limiting plate 61 reduces the probability of the slide bar 41 separating from the sliding hole 4, thereby improving the stability of the device.
[0041] The lower part of the filter element 11 does not have filter holes 14, so the cleaning plate 32 cannot clean the impurities on the surface of the filter element 11. Therefore, the lower part of the filter element 11 does not have filter holes 14.
[0042] To reduce noise, the surface of filter element 11 is coated with a sound-absorbing material. The sound-absorbing material reduces the probability that filter element 11 will be too noisy when the scraper 42 cleans it.
[0043] The operating principle of the energy-saving chiller unit of the refrigeration equipment in this embodiment is as follows: After the condenser converts the gas into liquid, the liquid flows into the filter cartridge 1 through the inlet pipe 12. Subsequently, it flows into the throttling valve through the outlet pipe 13. During this process, the filter holes 14 on the surface of the filter element 11 filter impurities in the water, causing the impurities to adhere to the surface of the filter element 11 or fall onto the inner bottom wall of the filter cartridge 1. Subsequently, when the staff needs to clean the filter element 11, the staff needs to activate the cleaning device 2 to clean the filter element 11. During this process, the cleaning device 2 eliminates the need for the staff to manually clean the filter element 11, thereby reducing the cleaning time and difficulty for the staff and improving the work efficiency of the staff.
[0044] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
