Description

Technical Field

[0001] This utility model relates to the technical field of supporting equipment for magnetic levitation fans, and in particular to a filtration system for dual-unit air supply of magnetic levitation fans. Background Technology

[0002] Magnetic levitation blowers are characterized by high efficiency, energy saving, low carbon emissions, environmental protection, and intelligent design. Their overall equipment performance is significantly better than that of traditional blowers. Therefore, they account for a large proportion of the current market for levitation blowers. Moreover, with the global focus on energy conservation and emission reduction, the application of magnetic levitation blowers is increasing year by year.

[0003] In practical applications of magnetic levitation fans, the industry currently mostly adopts a "one machine, one filter" air supply and filtration mode, meaning each fan is equipped with an independent filtration system. This increases the initial investment in equipment, and the application of the filtration system is not complete. At the same time, impurities easily accumulate in the filtration system, especially in areas with high dust levels. If cleaning is not done in time, it will lead to increased air intake resistance and affect the fan's operating efficiency. Cleaning and replacing the filter screen requires disassembling the filtration system, but the high frequency of cleaning and replacing the filter screen results in a poor user experience and also increases the cost of purchasing filter screens for users. Utility Model Content

[0004] To address the issues of excessive investment in magnetic levitation fans and untimely cleaning of filtration systems in the aforementioned background technology, this utility model provides a filtration system for dual-unit air supply to magnetic levitation fans.

The air outlet of the air filter is connected to a switching valve via a flexible joint. The switching valve is connected to the air inlet of the tee via the connecting pipe. The two air outlets of the tee are respectively connected to two independent control valves via connecting pipes. The control valves are connected to the air inlet of the magnetic levitation blower via flexible joints.

[0006] Preferably, the air filter includes a filter chamber, and a filter screen is installed inside the filter chamber. The filter screen divides the filter chamber into an air inlet chamber and an air outlet chamber. The edge of the filter screen is snapped and fixed to a limiting protrusion on the inner wall of the filter chamber.

[0007] Preferably, the air outlet chamber is equipped with an air inlet port, which is connected to a compressed air pipe, and the compressed air pipe is connected to a high-pressure air source.

[0008] Preferably, the air inlet port is connected to an air pipe and extends into the air outlet chamber. The air pipe connects to multiple branch pipes and a nozzle is installed at the end of the branch pipe, with the nozzle facing the filter plate. The air inlet chamber is detachably fitted with louvers at the connection point with the outside via bolts.

[0009] Preferably, the adjustment pipe comprises multiple sections of spliced ​​metal pipe, and the adjustment pipe is adapted to the height difference between the air filter and the air inlet of the two magnetic levitation blowers.

[0010] Preferably, the control valve is an electric disc valve, and the control valve is communicatively connected to an external controller.

[0011] Preferably, the elastic joint is a rubber elastic joint, with flanges snapped and fixed at both ends. The elastic joint is connected to the air filter, adjusting pipe, control valve, and magnetic levitation blower via flanges.

[0012] In summary, this utility model has the following beneficial technical effects: 1. This utility model optimizes the arrangement of the magnetic levitation fan and the air filter, so that one air filter supplies filtered gas to two fans, thus making full use of the filtration system and reducing equipment purchase costs and floor space.

[0013] 2. This utility model installs a filter plate inside the air filter and sets up an air inlet port to connect to an external high-pressure air source. The high-pressure airflow back-blown the dust on the filter plate, which effectively reduces the cost of frequently replacing the built-in filter in the cabinet and the frequency of manual filter replacement in dusty application environments. It only requires periodically back-blowing the filter plate and collecting the back-blown dust, thus improving the user's experience of using the equipment. Attached Figure Description

[0016] The following combination Figures 1-5 The present invention will be described in further detail below.

[0017] This utility model discloses a filtration system for dual-machine air supply of magnetic levitation fans.

[0018] Reference Figure 1 A filtration system for dual-unit air supply of magnetic levitation blowers includes an air filter 1, an adjusting pipe 2, a tee 3, and a connecting pipe 4. The outlet of the air filter 1 is connected to a switching valve 21 via a flexible joint 6. The switching valve 21 is connected to the inlet of the tee 3 via the connecting pipe 4. The two outlets of the tee 3 are respectively connected to two independent control valves 5 via the connecting pipe 4. The control valves 5 are connected to the inlet of the magnetic levitation blower 16 via the flexible joint 6. The tee 3 divides the filtered gas into two paths to provide clean gas to the two magnetic levitation blowers 16.

[0019] Reference Figure 2 , Figure 3 The air filter 1 includes a filter chamber 7, inside which a filter screen plate 8 is installed. The filter screen plate 8 divides the filter chamber 7 into an inlet chamber 9 and an outlet chamber 10. The edge of the filter screen plate 8 is snapped and fixed to a limiting protrusion 11 on the inner wall of the filter chamber 7. The outlet chamber 10 is equipped with an air inlet port 12, which is connected to a compressed air pipe 13. The compressed air pipe 13 is connected to a high-pressure air source, which is usually set as an air compressor. When the air compressor is started, it supplies air and inputs high-pressure air into the outlet chamber 10. The air inlet port 12 is connected to the air pipe 18 and extends into the air outlet chamber 10. The air pipe 18 is connected to multiple branch pipes 19 and a nozzle 20 is installed at the end of the branch pipe 19. The nozzle 20 faces the filter plate 8. The air pipe 18 introduces high-pressure airflow to flush the filter plate 8. A louver 14 is detachably installed at the position where the air inlet chamber 9 communicates with the outside through bolts.

[0020] Reference Figure 1 , Figure 4 The adjustment pipe 2 includes multiple sections of spliced ​​metal pipe 15, and the adjustment pipe 2 is adapted to the height difference between the air filter 1 and the air inlet of the two magnetic levitation blowers 16.

[0021] In practical applications of magnetic levitation blowers, the positions of each device are usually fixed. Therefore, by splicing multiple sections of metal pipe 15, the connection between the air filter 1 and the air inlet of the two magnetic levitation blowers 16 can be achieved. For some devices in different positions, a flexible hose structure can also be used to adjust the pipe 2.

[0022] Reference Figure 1 The control valve 5 is an electric disc valve used to independently control the opening and closing of the air intake pipe of the magnetic levitation blower 16. The control valve 5 is connected to an external controller, which includes a remote terminal and outputs control signals to the control valve 5. The control valve 5 receives and feeds back the signals to realize remote control of the air intake status of the magnetic levitation blower.

[0023] The switching valve 21 also uses an electric disc valve structure to independently control the opening and closing of the air outlet pipeline of the air filter 1. The switching valve 21 is connected to an external controller and is closed when high-pressure air is input to backflush the filter plate 8 to ensure that the airflow flows to the filter plate 8.

[0024] To reduce equipment purchase costs, control valve 5 and switch valve 21 can also be set as manual disc valves, and control valve 5 and switch valve 21 can be manually adjusted to open and close the air inlet pipe of magnetic levitation blower 16 and the air outlet pipe of air filter 1.

[0025] Reference Figure 1 , Figure 2 , Figure 5 The elastic joint 6 is a rubber elastic joint. Flanges 17 are snapped and fixed at both ends of the elastic joint 6. The elastic joint 6 is connected to the air filter 1, the adjusting pipe 2, the control valve 5 and the magnetic levitation blower 16 through the flanges 17.

[0026] The implementation principle of a filtration system with dual air supply from a magnetic levitation fan, as described in this embodiment of the utility model, is as follows: Assemble the adjustment pipe 2 that adapts to the height difference between the air filter 1 and the air inlet of the two magnetic levitation blowers 16, and connect other components. After the air is filtered by the air filter 1, it passes through the adjustment pipe 2, the tee 3, the connecting pipe 4, and is controlled by the control valve 5 to enter the magnetic levitation blower 16, so as to provide filtered clean air to the two magnetic levitation blowers.

[0027] When only one of the magnetic levitation blowers 16 is running, one of the control valves is closed. After being filtered by the air filter 1, the air enters the magnetic levitation blower 16 through the pipeline, thus providing filtered clean air for the operation of a single magnetic levitation blower 16.

[0028] After a long period of operation, dust will accumulate on the filter screen 8 in the air filter 1, which will increase the air intake resistance and affect the operating efficiency of the fan. At this time, the compressed air pipe 13 is connected to the air inlet port 12 of the air outlet chamber 10, the switch valve 21 is closed, and high-pressure air is introduced to automatically back-blow and clean the dust attached to the filter screen 8, so as to achieve normal and stable operation of the filtration system.

[0029] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
