Description

Technical Field

[0001] This utility model relates to the field of industrial chilled water technology, and in particular to an air-cooled chiller with easy filter replacement. Background Technology

[0002] An air-cooled chiller mainly consists of components such as a compressor, air-cooling device, filter, throttling valve, and water tank. Air-cooled chillers are primarily used for cooling in plastic processing and temperature control in machine tool lubrication systems.

[0003] To prevent the refrigerant in air-cooled chillers from accumulating particulate impurities after long-term use, which could lead to blockages in components such as the expansion valve, existing air-cooled chillers are equipped with filters. However, the filters used in existing air-cooled chillers are integrated structures, and replacing the filter requires disassembling the inlet and outlet pipes on both sides of the filter, making replacement inconvenient. Utility Model Content

[0004] The purpose of this invention is to address the inconvenience of filter replacement in existing technologies by proposing an air-cooled chiller that facilitates filter replacement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a filter-replaceable air-cooled chiller, including a housing, within which a water tank, a compressor, and an air-cooling device are installed, and further comprising:

[0007] The quick-change filter assembly includes a housing. The input and output terminals on both sides of the housing are connected to an air-cooling device and a water tank, respectively. A first slot is provided in the middle of the housing. An installation rod is rotatably installed at the opening of the first slot. Filter screens are movably installed at both ends of the installation rod. A movable shell is movably installed at the opening of the first slot, and the movable shell is fitted around the filter screen.

[0008] Preferably, the filter screen has a semi-circular structure, and the mounting rod and the combination of the two sets of filter screens form a circular structure.

[0009] Preferably, a rotating shaft is movably inserted at the central axis of the mounting rod, and the rotation of the mounting rod can be controlled by turning the rotating shaft.

[0010] Preferably, a second slot is formed inside the first slot, and the edge of the filter screen can slide inside the second slot.

[0011] Preferably, the inner end face of the movable shell has a second groove that mates with the filter screen.

[0012] Preferably, the opening of the first slot is integrally formed with a mounting groove, and the lower end of the movable shell can be slidably installed inside the mounting groove.

[0013] Preferably, a sealing gasket is nested on the inner end face of the first slot, which slides against the mounting rod.

[0014] The air-cooled chiller with easy filter replacement proposed in this utility model has the following advantages:

[0015] The mounting rod allows for the installation of filters on both sides. During use, only one side of the filter can be used, while the other side can be used as a spare. When the filter needs to be replaced, simply rotate the rotating shaft to switch between the two filters without stopping the machine.

[0016] Since the switching can be performed without shutting down the system, when the pressure gauge shows an increase in the reading in the pipeline, the filter screen can be switched to test whether the cause of the fault is filter blockage, thus playing a role in troubleshooting.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Reference Figures 1-6 An air-cooled chiller with easy filter replacement includes a housing 1, a water tank 2, a compressor 3, and an air-cooling device 4 installed inside the housing 1, and further includes:

[0027] The quick-change filter assembly includes a housing 5. The input and output terminals on both sides of the housing 5 are connected to the air-cooling device 4 and the water tank 2, respectively. A first slot 6 is provided in the middle of the housing 5. An installation rod 10 is rotatably installed at the opening of the first slot 6. Filter screens 11 are movably installed at both the upper and lower ends of the installation rod 10. A movable shell 9 is movably installed at the opening of the first slot 6 and is fitted around the filter screen 11.

[0028] Furthermore, refer to Figures 3-5 The filter screen 11 has a semi-circular structure, and the assembly of the mounting rod 10 and the two sets of filter screens 11 forms a circular structure. Figure 5 The image shows that the filter screen 11 and the mounting rod 10 are connected by a T-shaped slot; a rotating shaft 12 is movably inserted at the central axis of the mounting rod 10, and the rotation of the mounting rod 10 can be controlled by turning the rotating shaft 12.

[0029] Furthermore, refer to Figure 3 , Figure 6 The first slot 6 has a second slot 7 inside, and the edge of the filter screen 11 can slide inside the second slot 7; the inner end face of the movable shell 9 has a second slot 7 that cooperates with the filter screen 11.

[0030] Furthermore, refer to Figure 4 , Figure 6 The opening of the first slot 6 is integrally formed with an installation groove 8, and the lower end of the movable shell 9 can be slidably installed inside the installation groove 8.

[0031] Furthermore, a sealing gasket that slides against the mounting rod 10 is nested on the inner end face of the first slot 6.

[0032] Working principle:

[0033] When it is necessary to switch the filter 11, manually rotate the rotating shaft 12. When the rotating shaft 12 rotates, it will drive the mounting rod 10 to rotate. Manually control the rotating shaft 12 to rotate 180 degrees. At this time, the filter 11 located in the movable shell 9 and the filter 11 located in the outer shell 5 will switch positions, thereby realizing the switching of the filter 11.

[0034] After the switching is completed, slide the movable shell 9 along the mounting groove 8. The movable shell 9 causes the filter screen 11 inside it to move. The movable shell 9 slides out along the mounting groove 8, and the filter screen 11 slides out along the mounting rod 10. The movable shell 9 and the filter screen 11 inside the movable shell 9 can then be removed. Since there is a sealing gasket between the mounting rod 10 and the first slot 6, the liquid inside the outer shell 5 will not leak through the gap between the mounting rod 10 and the first slot 6. After that, remove the old filter screen 11 from the movable shell 9 and put in the new filter screen 11. When placing the filter screen 11, the filter screen 11 can be placed in the second slot 7 opened inside the movable housing 9 to prevent the filter screen 11 from shaking. After the filter screen 11 is replaced, the movable housing 9 is sent in along the mounting slide 8, and the filter screen 11 located inside the movable housing 9 will also be sent in, so that the mounting slide 8 is combined with the movable housing 9, the mounting rod 10 is combined with the filter screen 11, and the new filter screen 11 is in a closed state. When replacing it next time, the rotating shaft 12 can be directly rotated to replace it, realizing the reservation of parts, so as to facilitate quick replacement of parts.

[0035] The second slot 7 is used to fix the position of the filter screen 11, and the first slot 6 is used to prevent the filter screen 11 from contacting the inner wall of the outer shell 5 when rotating, so as to prevent the impurities adsorbed in the filter screen 11 from being scraped into the interior of the outer shell 5.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
