Detailed Implementation

[0025] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figures 1-6 As shown, an improved magnetic levitation variable frequency chiller unit includes a condenser 1, a frequency converter 2, a control cabinet 3, an economizer 4, an evaporator 5, a magnetic levitation compressor 6, an inlet pipe 7, and an outlet pipe 8. The inlet pipe 7 is equipped with a filter box 9, which has an inlet port 10 and an outlet port 11. The inlet port 10 is equipped with an inlet pipe 12, and the outlet port 11 is connected to the inlet pipe 7.

[0027] The filter box 9 is equipped with a mounting slot 13, and the mounting slot 13 is equipped with a filter plate 14.

[0028] Working principle explanation:

[0029] Example 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, after water is supplied to the equipment, the liquid enters the inlet pipe 12, then enters the filter box 9 for filtration, and then enters the water inlet pipe 7. The liquid is processed through the condenser 1, frequency converter 2, control cabinet 3, economizer 4, evaporator 5, and magnetic levitation compressor 6, and then discharged through the outlet pipe 8, achieving the effect of a chiller unit. It is worth noting that when the liquid enters the inlet pipe 12 and the inlet 10, the liquid is filtered for impurities by the filter plate 14 in the filter box 9, and the clean water enters the chiller unit for treatment through the outlet 11 and the inlet pipe 7.

[0030] Example 2, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment adds the following structure to the embodiment 1: the filter box 9 is provided with a drain port 15, the drain port 15 is equipped with a drain pipe 16, the filter box 9 is equipped with a first motor 17, the power output end of the first motor 17 is equipped with a rotating shaft 18, the rotating shaft 18 is fixedly equipped with a stop block 19 that matches the drain pipe 16, and the drain pipe 16 is connected to an impurity box 20. It is worth noting that when it is necessary to discharge the filtered impurities, the first motor 17 is started to make the rotating shaft 18 rotate, which drives the stop block 19 to rotate and discharge the filtered impurities into the impurity box 20 through the drain pipe 16. This structural design allows the impurities filtered by the filter box 9 to be discharged, making the equipment cleaning more convenient.

[0031] Example 3, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment adds the following structure based on embodiment 1: the filter box 9 is equipped with a first slide groove 21, the filter box 9 is equipped with a second motor 22, the power output end of the second motor 22 is equipped with a threaded rod 23, the threaded rod 23 is threadedly equipped with a slider 24 that matches the first slide groove 21, the slider 24 is equipped with a brush body 25 that matches the filter plate 14, and the bottom of the mounting groove 13 is equipped with a guide block 26 that matches the drain pipe 16. It is worth noting that when the filter plate 14 needs to be cleaned, the second motor 22 is started to make the threaded rod 23 rotate and drive the slider 24 to move in the first slide groove 21. The movement of the slider 24 drives the brush body 25 to scrape the impurities on the filter plate 14 onto the stop block 19. This structural design makes cleaning the filter plate 14 more convenient and saves more manpower.

[0032] Example 4, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment adds the following structure based on embodiment 1: the filter box 9 is equipped with a hinge member 27, the hinge member 27 is equipped with a cover plate 28, the cover plate 28 is equipped with a first fixing block 29, the first fixing block 29 is equipped with a limit block 30, the filter box 9 is equipped with a second fixing block 31, the second fixing block 31 is provided with a groove 37 matching the limit block 30, the second fixing block 31 is provided with a second sliding groove 32, the second sliding groove 32 is equipped with a spring 33, the spring 33 is equipped with a pressure block 34 matching the second sliding groove 32, the pressure block 34 is equipped with a limit rod 35, and the limit block 30 is provided with a limit hole 36 matching the limit rod 35. It is worth noting that when it is necessary to install or remove... When the cover 28 needs to be opened to remove the filter plate 14, the limiting rod 35 is pulled to compress the spring 33 by the pressure block 34. The limiting rod 35 then disengages from the limiting hole 36, allowing the cover 28 to be opened. Similarly, when closing the cover 28, the limiting block 30 contacts the limiting rod 35, causing the limiting rod 35 to be forced to compress the spring 33 by the pressure block 34. After the limiting block 30 is fully inserted into the groove 37, the spring 33 rebounds, causing the pressure block 34 to insert the limiting rod 35 into the limiting hole 36 to fix the limiting block 30. This structural design makes it easier to open and close the cover 28, and the cover 28 is more securely closed, reducing the amount of dust entering the filter box 9. It also makes it easier to replace the filter plate 14.

[0033] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
