Description

Filtration system This invention relates to a filtration device, and more particularly to a negative pressure reverse osmosis filtration device and filtration system. Referring to Figure 1, a conventional filter device 1 mainly includes a cylindrical component 11, a top cover 12 and a bottom cover 13 sealing two opposite ends of the cylindrical component 11, and an impeller 14 installed between the top cover 12 and the cylindrical component 11. The cylindrical component 11 defines a vortex chamber 110 around an axis X. The top cover 12 has an inlet 121 and an outlet 122 formed on two opposite sides and respectively connected to the vortex chamber 110. When foreign matter such as oil and water mist, black smoke, dust or exhaust gas enters the vortex chamber 110 of the cylinder 11 along the direction of the solid arrow from the inlet 121 of the top cover 12, a vortex as shown by the ribbon arrow in the figure will be generated in the vortex chamber 110. Centrifugal force will throw the foreign matter brought in by the airflow out, causing the foreign matter to fall along the wall of the cylinder 11 and be deposited at the bottom end 112 of the cylinder 11. Finally, the airflow without foreign matter will be discharged from the outlet 122 of the top cover 12. However, the aforementioned method of using vortices to throw out foreign matter in the airflow is only effective for foreign matter with a certain weight or size. Foreign matter or harmful substances with smaller particle size or dissolved in liquid will still exist in the fluid, thereby damaging the components through which the fluid flows, such as blowers. Therefore, how to capture and filter out smaller foreign matter in the fluid to improve fluid cleanliness is a problem that the industry is trying to overcome. Therefore, the object of the present invention is to provide a negative pressure reverse osmosis filtration device that can improve the cleanliness of fluids. Therefore, the negative pressure reverse osmosis filtration device of the present invention includes a cylindrical component, a connecting cover, an end cover unit, and a reverse osmosis filter element. The cylindrical component includes two oppositely arranged ends. The connecting cover is detachably disposed at one of the ends and includes two openings for fluid inlet and outlet. The end cap unit is detachably disposed at the other end and has an inner annular conical surface formed on the inner surface. The reverse osmosis filter element extends along an axis within the cylindrical component and abuts against the connecting cap and the end cap unit. The reverse osmosis filter element surrounds the axis and defines a conduit, and includes an outer conical surface that corresponds to and abuts against the inner conical surface. The reverse osmosis filter element and the cylindrical component define a chamber. The chamber and one of the openings of the connecting cap define a first flow channel for fluid passage. The conduit and the other opening of the connecting cap define a second flow channel for fluid passage. One of the first and second flow channels forms a negative pressure state to drive water molecules through the reverse osmosis filter element. Therefore, the filtration system of the present invention includes at least one negative pressure reverse osmosis filtration device as described above, at least one heat exchange device, a connecting device, and a driving device. The at least one heat exchange device is used to regulate the temperature of the fluid passing through. The connection device includes a plurality of connection units, each of which is selectively and detachably connected to the at least one heat exchange device and the at least one negative pressure reverse osmosis filter device. The drive device is connected to the connecting device and is used to drive the fluid to flow between the at least one negative pressure reverse osmosis filter and the at least one heat exchange device. The advantages of this invention are: the fluid in the first flow channel is driven by a negative pressure environment, passes through the reverse osmosis filter and enters the second flow channel. The reverse osmosis filter filters the fluid, which can block most harmful substances and impurities, thereby improving the cleanliness of the fluid. Referring to Figures 2, 3, and 4, an embodiment of the negative pressure reverse osmosis filtration device of the present invention includes a cylindrical component 2, a connecting cover 3, an end cover unit 4, and a reverse osmosis filter element 5. The cylindrical component 2 includes two ends 21 arranged in opposite directions along an axis L. The connecting cap 3 is detachably disposed at one of the ends 21 and includes a tube portion 32 surrounding the axis L and defining a channel 31, and a body portion 34 surrounding the tube portion 32 and defining an annular channel 33 therewith. The body portion 34 has two opposing annular edges 35. Each annular edge 35 defines a cover opening 36 for fluid inlet and outlet. One cover opening 36 communicates with the annular channel 33, and the other cover opening 36 communicates with the channel 31. The channel 31 is not connected to the annular channel 33. The end cap unit 4 is detachably disposed at the other end 21 and includes an end cap 41 surrounding the axis L, a sealing cap 42 spaced apart from the end cap 41 along the extending direction of the axis L, a water-stopping member 43 disposed between the end cap 41 and the sealing cap 42, and a fixing assembly 44 detachably disposed on the end cap 41 and the sealing cap 42 and positioning the sealing cap 42 relative to the end cap 41. The end cap 41 defines a port 411 open along the extending direction of the axis L and has an inner annular conical surface 412 formed on its inner surface. In this embodiment, the fixing assembly 44 is configured as a C-shaped retaining ring, and the opposite ends of the C-shaped retaining ring are brought close together by screws to press the sealing cap 42 toward the end cap 41. The reverse osmosis filter element 5 extends along the axis L and passes through the cylindrical component 2, abutting against the connecting cap 3 and the end cap unit 4. The reverse osmosis filter element 5 includes an inner tube surface 51 surrounding the axis L, an outer tube surface 52 radially located outside the inner tube surface 51 along the axis L, a first annular surface 53 and a second annular surface 54 arranged opposite to each other along the axis L, and an outer annular conical surface 55 corresponding to and abutting against the inner annular conical surface 412. The inner tube surface 51 defines a conduit 511. The first annular surface 53 faces the connecting cap 3 and connects the outer tube surface 52 and the inner tube surface 51. The second annular surface 54 connects to the inner tube surface 51, and the outer annular conical surface 55 connects the second annular surface 54 and the outer tube surface 52. The reverse osmosis filter element 5 also has an embedding groove 531 formed on the first annular surface 53, into which the tube body portion 32 of the connecting cover 3 extends. More specifically, the outer tube surface 52 of the reverse osmosis filter element 5 and the cylindrical member 2 define a chamber 521. The annular channel 33, the chamber, and one of the openings 36 of the connecting cover 3 together define a first flow channel suitable for fluid passage. The orifice 31, the pipe 511, and the other opening 36 of the connecting cover 3 together define a second flow channel suitable for fluid passage. The second flow channel forms a negative pressure state to drive water molecules through the reverse osmosis filter element 5. It should be noted that in this embodiment, the cylindrical component 2, the connecting cover 3, and the end cover 41 are made of aluminum. In other embodiments, other metal materials with higher thermal conductivity, such as copper, may also be selected as needed. It should be noted that the negative pressure reverse osmosis filtration device of the present invention is not limited to being connected in series or in parallel. During assembly, as shown in FIG5, a connecting device 6 can be used to connect multiple embodiments in series, so that the fluid passes through the first flow channel and the second flow channel of the negative pressure reverse osmosis filtration device in an alternating manner, and is filtered through multiple reverse osmosis filter elements 5, thereby further improving the cleanliness of the fluid. The connecting device 6 includes a plurality of connecting units 61, each of which is selectively and detachably connected to the negative pressure reverse osmosis filtration device. Alternatively, during assembly, as shown in Figure 6, the connecting device 6 can be used to connect this embodiment and a filter module 7. The aforementioned filter module 7 can be a cyclone separator filter module disclosed in Republic of China Patent No. 1589344, or a cyclone filter device disclosed in Republic of China Patent Publication No. 201912230. The filter module 7 has a channel 71 for fluid passage and a trapping element 72 that crosses the channel 71, which can block larger particle sizes of foreign matter from passing through. Since these are not technical features of this application, and those skilled in the art can infer extended details from the above description, they will not be described further. Referring to Figures 7 and 8, the present invention can form a filtration system using the negative pressure reverse osmosis filtration device, the connecting device 6, a heat exchange device 8, and a driving device 9. The connection device 6 also includes a plurality of pipes 62 that are connected to the negative pressure reverse osmosis filter, the heat exchange device 8 and the drive device 9 through the connection units 61. The heat exchange device 8 is used to regulate the temperature of the fluid passing through it, and includes a housing unit 81, a pipe unit 82, a cyclone ring 83, a linkage unit 84, and a condensation unit 85. The housing unit 81 includes an outer cylinder 811 and two housing covers 812 disposed at opposite ends of the outer cylinder 811. The outer cylinder 811 and the tubular unit 82 together define a vortex chamber 813. Each housing cover 812 has two openings 814 disposed in opposite directions. The tubular unit 82 is inserted into the outer cylinder 811 and includes two hollow tubular components 821 respectively disposed on the shell covers 812, and an adjusting tube 822 screwed to one of the hollow tubular components 821 and located between the hollow tubular components 821. Each hollow tubular component 821 defines a flow space 823, and the other hollow tubular component 821 is separated from the adjusting tube 822 by a gap 824. The flow spaces 823 and one opening 814 of each shell cover 812 define a third flow channel suitable for fluid passage, and the vortex chamber 813 and another opening 814 of each shell cover 812 define a fourth flow channel suitable for fluid passage.

The operating member 843 can be operated to rotate the rotating rod 841, thereby driving the adjusting tube 822 to rotate relative to the first tube, so as to enlarge or reduce the gap 824. The condensation unit 85 is disposed on another housing 812. The condensation unit 85 includes a cooling wafer module 851 and a heat dissipation module 852 in contact with the cooling wafer module 851. The cooling wafer module 851 is used to lower the fluid temperature inside the housing unit 81. When the condensation unit 85 is connected to direct current, heat energy can be released by the heat dissipation module 852 through the Peltier effect of the cooling wafer module 851. The drive device 9 is connected to the connecting device 6 and is used to drive the fluid to flow between the negative pressure reverse osmosis filter and the heat exchange device 8. The drive device 9 includes a motor 91 and a blower 92 that connects to the pipes 62 and is driven by the motor 91 to drive the fluid flow. Compared to existing filtration devices, this invention utilizes a negative pressure environment to drive the fluid in the first flow channel through the reverse osmosis filter element 5 and then into the second flow channel. Based on the above description, the advantages of the aforementioned embodiments can be summarized as follows: 1. The present invention utilizes the reverse osmosis filter element 5, which has pores smaller than 0.001 micrometers, allowing only water molecules and substances smaller than water molecules to pass through, thereby blocking most harmful substances and impurities and improving the cleanliness of the fluid. 2. The reverse osmosis filter element 5 can restore its filtration function after cleaning and can be reused, replacing filter consumables that must be discarded after a period of use, thus reducing waste. 3. By matching the inner ring conical surface 412 with the outer ring conical surface 55, the end cap 41 can be installed to position the reverse osmosis filter element 5 and press it against the connecting cap 3. There is no need for complicated mechanisms and complicated installation procedures, which achieves the effect of easy assembly and cost saving. 4. This invention can be widely applied in the fields of cooling, filtration, or processing through modular design. It can not only improve the cleanliness of fluids to enhance the quality of each finished product in the processing process, but also reduce foreign matter and harmful substances in the fluid, thereby increasing the service life of the components through which the fluid passes.
