[0001] The utility model belongs to the technical field of chillers, and in particular relates to a magnetic suspension variable frequency chiller. Background Art

[0002] A magnetic levitation variable frequency chiller is a high-efficiency chiller that utilizes magnetic levitation technology and variable frequency control technology. It uses magnetic force to suspend the compressor rotor in the air, avoiding the friction of traditional mechanical bearings, reducing energy loss and wear, and improving the operating efficiency and reliability of the compressor. To achieve water recycling, the corresponding cooling system will be equipped with corresponding water treatment equipment, such as filters and softeners, to remove impurities, dirt, and hardness ions in the water to prevent them from accumulating in pipes and equipment, affecting the normal operation of the system and heat exchange efficiency.

[0003] However, in the prior art, processing equipment such as filters are usually arranged inside the unit, which makes it inconvenient to replace the filter element of the filter. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the present invention is to provide a magnetic levitation variable frequency chiller to solve the problems raised by the above background technology.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0006] A magnetic levitation variable frequency chiller, comprising a magnetic levitation chiller body, characterized in that: the magnetic levitation chiller body is provided with a water inlet and a water outlet, the water inlet and the water outlet are both provided with a filter element, the filter element is detachably connected to the water inlet and the water outlet, the two ends of the filter element are connecting pipes, the connecting pipes are fixedly connected with a connecting shell, a filter plate and a flow limiting mechanism are provided inside the connecting shell, a filter plate outlet is opened above the connecting shell, an anti-overflow frame is fixedly connected to the outside of the outlet of the connecting shell, the anti-overflow frame is sealed with a sealing cover, and the lower side of the sealing cover abuts the filter plate.

[0007] It is further defined that the upper side frame portion of the filter plate is located on the upper side of the connecting shell, and a slot is provided laterally on the upper side frame of the filter plate. An inverted T-shaped limit plate is slidably connected in the slot of the filter plate, and the vertical plate on the upper side of the limit plate is biased toward the water inlet side, and a handle groove is provided on the vertical plate of the limit plate.

[0008] It is further defined that a collection frame is fixedly connected below the filter plate, and the collection frame is located on a side of the filter plate close to the water inlet.

[0009] It is further defined that the flow limiting mechanism includes a baffle with a circular opening on the side close to the water inlet, a water sealing plate on the side of the baffle away from the water inlet, a circular ring fixedly connected to the edge of one side of the water sealing plate, a positioning plate fixedly connected to the connecting shell on the side close to the filter element, a water groove on the positioning plate, and an elastic member is provided between the positioning plate and the water sealing plate, and the elastic member is used to make the circular ring abut against the baffle.

[0010] It is further defined that the elastic member is a spring, a cylindrical groove is opened in the middle of the positioning plate, the spring is located in the cylindrical groove, the spring is located in the cylindrical groove, the side of the water sealing plate close to the filter plate is fixedly connected to a limiting column, the limiting column is located in the spring, and at the same time passes through the circular hole opened in the middle of the positioning plate.

[0011] It is further defined that the end of the connecting pipe is fixedly connected to a flange.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The filter plate of the utility model can be taken out from the outlet of the filter plate, so that the filter plate can be cleaned and replaced. By arranging a card slot above the filter plate, when the vertical plate of the limit plate contacts the side of the filter plate, the limit plate and the filter plate can be taken out at the same time, and when one side of the limit plate is pushed to the lower side of the connecting shell, the limit plate is located below the card slot of the filter plate and the connecting shell, so that the filter plate is stuck in the connecting shell.

[0014] The utility model has a simple structure and can limit the flow direction of water through the flow limiting mechanism, thereby preventing water in the connecting shell from flowing back into the connecting pipe. The design is ingenious. When water flows out, the water flow squeezes the water sealing plate to one side, thereby forming a gap between the water sealing plate and the baffle for water to pass through.

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0028] like Figure 1-6 As shown, a magnetic levitation variable frequency chiller includes a magnetic levitation chiller body 1, the magnetic levitation chiller body 1 is provided with a water inlet 11 and a water outlet 12, the water inlet 11 and the water outlet 12 are both provided with a filter element 2, the filter element 2 is detachably connected to the water inlet 11 and the water outlet 12, both ends of the filter element 2 are connecting pipes 21, the connecting pipes 21 are fixedly connected with a connecting shell 22, a filter plate 23 and a flow limiting mechanism 4 are provided inside the connecting shell 22, a filter plate 23 outlet is opened above the connecting shell 22, an anti-overflow frame 25 is fixedly connected to the outside of the outlet of the connecting shell 22, the anti-overflow frame 25 is sealed with a sealing cover 26, and the lower side of the sealing cover 26 abuts against the filter plate 23.

[0029] Using the technical solution of this embodiment, the filter plate 23 is used to filter the water entering the magnetic levitation chiller body 1 from the water inlet 11 and the water discharged from the water outlet 12 of the magnetic levitation chiller body 1, thereby keeping the water source of the recycled water clean. The connecting pipe 21 is connected to the magnetic levitation chiller body 1, and the current limiting mechanism 4 is used to limit the direction of water flow to prevent the backflow of water in the connecting shell 22. After the sealing cover 26 is removed from the anti-overflow frame 25, the filter plate 23 can be removed from the top of the connecting shell 22, so that the filter plate 23 can be replaced or cleaned.

[0030] Reference Figure 4 and 6The upper frame portion of the filter plate 23 is located on the upper side of the connecting shell 22. A slot is provided in the transverse direction of the upper frame portion of the filter plate 23. An inverted T-shaped limit plate 3 is slidably connected to the slot of the filter plate 23. The upper vertical plate of the limit plate 3 is biased toward the water inlet side, and the vertical plate of the limit plate 3 is provided with a handle slot. In this embodiment, the water inlet is different from the water inlet 11. The water inlet, relative to the water inlet, refers to the side where water enters the main body 1 of the magnetic levitation chiller. The water inlet, relative to the water outlet 12, refers to the side where water exits the main body 1 of the magnetic levitation chiller. When the limit plate 3 is moved in a direction away from the filter plate 23, the upper side of the limit plate 3 abuts against the lower side of the connecting shell 22, and the other side is partially located in the slot.

[0031] Reference Figure 6 : A collecting frame 231 is fixedly connected below the filter plate 23, and the collecting frame 231 is located on one side of the filter plate 23 near the water inlet. In the present embodiment, the collecting frame 231 collects impurities, and when the filter plate 23 is taken out, the collecting frame 231 can be taken out at the same time.

[0032] Reference Figure 4 The flow limiting mechanism 4 includes a baffle 41 with a circular opening near the water inlet, a water sealing plate 42 on the side of the baffle 41 away from the water inlet, a circular ring 43 fixedly connected to one edge of the water sealing plate 42, and a positioning plate 44 fixedly connected to the connecting shell 22 near the filter element 2. The positioning plate 44 has a water passage, and an elastic member is provided between the positioning plate 44 and the water sealing plate 42, and the elastic member is used to make the circular ring 43 abut against the baffle 41. In this embodiment, the water sealing plate 42 is abutted against the baffle 41 by the elastic member. When the circular ring 43 of the water sealing plate 42 abuts against the baffle 41, water in the connecting shell 22 cannot enter the side of the water inlet. When water enters one side of the water inlet, the water flow pushes the water sealing plate 42 to move toward the other side of the water inlet, so that water flows into the connecting shell 22 through the gap between the water sealing plate 42 and the baffle 41.

[0033] Reference Figure 3-5 The elastic member is a spring 45. A cylindrical groove is defined in the center of the positioning plate 44. The spring 45 is positioned within the cylindrical groove. A limiting post 46 is fixedly connected to the side of the water sealing plate 42 proximate to the filter plate 23. The limiting post 46 is located within the spring 45 and extends through a circular hole defined in the center of the positioning plate 44. In this embodiment, the limiting post 46 extends through the circular hole defined in the center of the positioning plate 44, thereby defining the position of the limiting post 46 and causing the spring 45 to abut against the water sealing plate 42.

[0034] Reference Figure 4 : The end of the connecting pipe 21 is fixedly connected with a flange 211. The flange 211 is used to connect the end of the connecting pipe 21 to the pipeline.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
