Description

Technical Field

[0001] The present application relates to the technical field of filtration equipment, and specifically to a stacked disc precision filtration device. Background Art

[0002] A filter is a device used to filter impurities from liquids or gases, and is commonly used in industrial production, environmental protection, water treatment, and other fields. Typically composed of filter media, filter elements, and filter screens, these devices use physical or chemical methods to separate impurities such as solid particles, microorganisms, and grease suspended in liquids or gases, thereby improving the purity and cleanliness of the liquid or gas.

[0003] Common filtration devices use a single-layer filter membrane for physical filtration operations. Due to the limited contact range of the single-layer filter membrane, its efficiency is low, especially under large-flow filtration conditions. The current multi-layer filtration device uses a multi-layer filtration method, which inevitably involves repeated filtration. It is only used to improve filtration accuracy, but filtration efficiency is still difficult to guarantee.

[0004] Based on the above existing filtering devices, a stacked disc precision filtering device is proposed to solve the above problems. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present application provides a stacked disc precision filtration device, which has the advantages of stacked filtration under large flow conditions and significantly improved filtration efficiency.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: a stacked disc precision filtration device, comprising a kettle body and a filter assembly built into the kettle body, the filter assembly comprising a porous plate frame installed inside the shell and a filter membrane and a concave plate located inside the porous plate frame, one end of the filter membrane and the concave plate are fixedly connected to the porous plate frame.

[0007] Furthermore, the outside of the kettle body is fixedly connected to a support frame for fixing. The kettle body includes a shell, a liquid inlet, a liquid outlet, a drain port and a sewage outlet connected to the shell, and also includes an exhaust port for discharging gas. A hanging pipe assembly is fixedly installed on the outside of the shell, and a spare port is also connected to the top of the shell.

[0008] Furthermore, the porous plate frame is disc-shaped and there are several of them, and the multiple porous plate frames are stacked to form a cylindrical shape with a hollow center.

[0009] Furthermore, a liquid inlet hole is formed through a side wall of the porous plate frame facing the outside, and a liquid outlet hole is formed through a side wall of the porous plate frame facing the inside.

[0010] Furthermore, the liquid inlet and the liquid outlet are arranged in an offset manner up and down on the porous plate frame, and one end of the filter membrane and the concave plate are fixedly connected to a position between adjacent liquid inlet holes on the porous plate frame. At the same time, the other end of the filter membrane passes through the liquid outlet, and one end of the filter membrane divides the liquid outlet into two parts separated by an upper and a lower barrier. One end of the concave plate facing the inner side of the porous plate frame is downwardly fixedly connected to the adjacent filter membrane, and the connection is located at the end position of the liquid outlet.

[0011] Furthermore, a support frame is fixedly connected to the lower bottom surface of the concave plate, and a support member located on the lower end of the concave plate is fixedly installed on the support frame. Through the support member, a raised portion can be formed on the surface of the concave plate, and the raised portion is attached to the filter membrane above.

[0012] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0013] The stacked disc precision filter device filters the raw liquid by continuously fixing multiple groups of filter membranes and concave plates stacked up and down in the filter assembly, so that the filter assembly can simultaneously achieve upper and lower multi-layer filtration to improve the filtration efficiency, and the clear liquid after multi-layer filtration can be discharged from the liquid outlet to achieve the concentration of the filtered liquid. Compared with the existing filter structure, the filtration efficiency is significantly improved, and it is suitable for large flow rates to increase the filtration area.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] See also Figure 1-3 In this embodiment, a stacked disc precision filter device includes a kettle body and a filter assembly 9 built into the kettle body, wherein the outside of the kettle body is fixedly connected to a support frame 10 for fixing. The kettle body includes a shell 1, a liquid inlet 2 connected to the shell 1, a liquid outlet 3, a drain port 4, and a sewage outlet 5;

[0020] It also includes an exhaust port 6 for exhausting gas, a hanging pipe assembly 7 is fixedly installed on the outside of the shell 1, and a spare port 8 is connected to the top of the shell 1.

[0021] It should be noted that the above-mentioned liquid inlet 2, liquid outlet 3, drain outlet 4, exhaust port 6, standby port 8 and sewage outlet 5 are all provided with valves for closing the pipelines.

[0022] In this embodiment, the filter assembly 9 includes a porous plate frame 901 installed inside the shell 1, a filter membrane 902 located inside the porous plate frame 901, and a concave plate 903. One end of the filter membrane 902 and the concave plate 903 are fixedly connected to the porous plate frame 901.

[0023] It is understandable that the porous plate frames 901 are disc-shaped and there are several of them. Several porous plate frames 901 are stacked to form a cylindrical shape with a hollow center, so as to facilitate the arrangement of multiple layers of concave plates 903 in the porous plate frames 901.

[0024] Specifically, the filter material of the filter membrane 902 can be PP, PE, PVDF, nylon, 304, 316L, special alloys, composite fibers and the like, and appropriate filter materials can be selected according to different working conditions.

[0025] It should be noted that a liquid inlet 11 is formed through a side wall of the porous plate frame 901 facing the outside, and a liquid outlet 12 is formed through a side wall of the porous plate frame 901 facing the inside.

[0026] In the present invention, the filtered liquid is fed into the shell 1 through the liquid inlet 2, and penetrates into the interior of the porous plate frame 901 through the liquid inlet hole 11 opened on the porous plate frame 901. After being blocked by the filter membrane 902, the filtered liquid can be discharged from the liquid outlet 12, and the filtered impurities remain between the filter membrane 902 and the concave plate 903.

[0027] Preferably, the liquid inlet 11 and the liquid outlet 12 are arranged in an upper and lower staggered manner on the porous plate frame 901, and one end of the filter membrane 902 and the concave plate 903 are fixedly connected to a position between adjacent liquid inlet holes 11 on the porous plate frame 901. At the same time, the other end of the filter membrane 902 passes through the liquid outlet 12, and one end of the filter membrane 902 divides the liquid outlet 12 into two parts with upper and lower barriers. The end of the concave plate 903 facing the inner side of the porous plate frame 901 is fixedly connected downward to the adjacent filter membrane 902, and the connection is located at the end position of the liquid outlet 12.

[0028] In a specific implementation, the raw liquid enters the porous plate frame 901 through the liquid inlet 11. At this time, the raw liquid is located between the upper concave plate 903 and the lower filter membrane 902. After the raw liquid is filtered by the lower filter membrane 902, the impurities are blocked in the part between the filter membrane 902 and the upper concave plate 903. The filtered raw liquid is discharged from the lower half of the liquid outlet hole 12 passed by the filter membrane 902 and the upper half of the lower liquid outlet hole 12 to the outside of the porous plate frame 901 for filtration.

[0029] In order to concentrate the filtered clear liquid and discharge it toward the liquid outlet 12, a support frame 14 is fixedly connected to the lower bottom surface of the concave plate 903 in this embodiment, and a support member 15 located on the lower end of the concave plate 903 is fixedly installed on the support frame 14. Through the support member 15, a raised portion 13 can be formed on the surface of the concave plate 903, and the raised portion 13 is attached to the filter membrane 902 above, so that the concave plate 903 and the filter membrane 902 can form an area for the clear liquid to flow with the inner wall of the porous plate frame 901.

[0030] The working principle of the above embodiment is:

[0031] The filtered liquid is fed into the shell 1 through the liquid inlet 2, and the raw liquid penetrates into the interior of the porous plate frame 901 through the liquid inlet hole 11 opened on the porous plate frame 901. At this time, the raw liquid is in the position between the upper concave plate 903 and the lower filter membrane 902. After the raw liquid is filtered by the lower filter membrane 902, the impurities are blocked in the part between the filter membrane 902 and the upper concave plate 903. The filtered raw liquid is discharged from the lower half of the liquid outlet hole 12 passed by the filter membrane 902 and the upper half of the lower liquid outlet hole 12 to the outside of the porous plate frame 901 for filtration. Since the filter membrane 902 is arranged in multiple layers above and below, multi-layer filtration with a large flow rate can be achieved within the upper and lower stacking range. Compared with the existing filtration method, the filtration efficiency is significantly improved.
