Description

Technical Field

[0001] This utility model relates to the technical field of cross-flow filtration equipment, specifically to a high-precision separation cross-flow filtration equipment. Background Technology

[0002] Cross-flow filtration equipment is a device that uses membrane separation technology to separate substances. Its working principle is that the liquid to be filtered flows parallel to the membrane surface at a certain speed. Part of the liquid permeates through the membrane and becomes permeate, while the remaining liquid continues to flow along the membrane surface, carrying away particles that cannot permeate the membrane in time, thereby reducing the contamination of the membrane surface and extending the filtration cycle and the service life of the membrane.

[0003] Existing technologies have poor filtration effects, and larger particles or impurities may directly enter the ceramic membrane, causing rapid clogging of the membrane pores, reducing filtration efficiency and shortening the membrane's lifespan. They also cause wear and tear on the conveying mechanism and the ceramic membrane, affecting the normal purification effect. Therefore, a high-precision separation cross-flow filtration device is needed. Utility Model Content

[0039] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0040] Example 1

[0041] Please see Figure 1 - Figure 5 A high-precision separation cross-flow filtration device includes a raw water pipe 1, a conveying pipe 2 fixedly installed at the bottom of the raw water pipe 1, an installation shell 3 connected to the other end of the conveying pipe 2, a filter cylinder 4 provided inside the installation shell 3, and two filter screens 5 fixedly installed on the inner wall of the filter cylinder 4.

[0042] A buffer assembly 6 is provided on the inner side of the mounting shell 3, and the filter cartridge 4 is fixed on the buffer assembly 6.

[0043] A first conveying component 7 and a second conveying component 8 are respectively provided on one side of the raw water pipe 1, and the input end of the first conveying component 7 is connected to the mounting shell 3, and the output end of the first conveying component 7 is connected to the second conveying component 8.

[0044] A filter housing 9 is fixedly installed on the output end of the second conveying component 8. A first connecting pipe 10 is fixedly installed on the top of the filter housing 9, and the other end of the first connecting pipe 10 is connected to the raw water pipe 1.

[0045] A discharge pipe 11 is fixedly installed on the outer wall of the filter housing 9, and a ceramic membrane 12 is installed inside the filter housing 9.

[0046] This utility model provides a high-precision cross-flow filtration device. In use, the liquid inside the raw water pipe 1 enters the filter shell 9 through the conveying pipe 2 and the mounting shell 3 via the first conveying component 7 and the second conveying component 8. Before entering, the liquid is initially filtered by the filter cylinder 4 and the filter screen 5 inside the mounting shell 3. At the same time, with the cooperation of the buffer component 6, the filter cylinder 4 and the water flow can be buffered to a certain extent, thereby intercepting larger particles and impurities, reducing the burden on the subsequent ceramic membrane 12 filtration, and reducing the pressure impact in the pipeline to prevent destructive water hammer. The liquid entering the filter shell 9 is then filtered by the ceramic membrane 12. The unfiltered concentrate is returned to the raw water pipe 1 through the first connecting pipe 10 and mixed with the original liquid for filtration again. This not only ensures the recycling of the original liquid, but also maintains the shear force and scouring force generated by the high flow rate on the membrane surface, ensuring the cleanliness of the ceramic membrane 12 surface.

[0047] Furthermore, the buffer assembly 6 includes an annular plate 61 fixedly installed on the inner wall of the mounting shell 3, and a plurality of T-shaped rods 62 are sequentially arranged in a circular array on the annular plate 61;

[0048] The other ends of multiple T-shaped rods 62 are fixedly installed on a ring frame 63, and the filter cartridge 4 is connected to the ring frame 63;

[0049] A spring 64 is fitted on the outer wall of the T-shaped rod 62, and the spring 64 is located between the annular plate 61 and the annular frame 63.

[0050] Specifically, after the raw liquid passes through the filter cylinder 4 and the filter screen 5, the filter cylinder 4 drives the annular frame 63 to move stably under the action of the annular plate 61 and the T-shaped rod 62, and squeezes the spring 64. Thus, under the action of the spring 64, the filter cylinder 4, the filter screen 5 and the water flow can be buffered to a certain extent, thereby reducing the pressure impact in the pipeline and preventing the destructive water hammer phenomenon.

[0051] Furthermore, two L-shaped grooves 14 are sequentially formed in a circular array on the outer wall of the ring frame 63, and two snap-fit ​​blocks 15 are fixedly installed on the outer wall of the filter cylinder 4, with the snap-fit ​​blocks 15 and the L-shaped grooves 14 being inserted into each other.

[0052] Specifically, the snap-fit ​​block 15 on the surface of the filter cartridge 4 is manually inserted into the L-shaped groove 14 on the annular frame 63, and then rotated to fix the filter cartridge 4 on the annular frame 63, thereby making it easier to disassemble, replace and clean the back of the filter cartridge 4.

[0053] Furthermore, the mounting shell 3 includes a fixed shell 31, and an annular plate 61 is fixedly installed on the inner wall of the fixed shell 31. A sealing cap 32 is threadedly connected to one side of the fixed shell 31, and a sealing ring 1 is fixedly installed on one side of the inner wall of the fixed shell 31, with the other side of the sealing ring 1 abutting against the fixed shell 31.

[0054] Specifically, the filter cartridge 4 can be easily removed from the fixed housing 31 for cleaning and replacement by manually unscrewing the threaded sealing cap 32 on the fixed housing 31.

[0055] Furthermore, a first flange 16 is fixedly installed on the end of the conveying pipe 2 away from the raw water pipe 1 and on the input end of the first conveying component 7. A second flange 17 is fixedly installed on one end of the fixed shell 31 and the sealing cover 32. The first flange 16 and the second flange 17 are locked together by bolts and nuts.

[0056] Specifically, the first flange 16 and the second flange 17, along with the bolts and nuts, allow the conveying pipe 2, the mounting shell 3, and the first conveying assembly 7 to be stably connected together. This allows the raw liquid in the raw water pipe 1 to enter the filter shell 9 for filtration, and also allows the mounting shell 3 to be disassembled and reassembled, making it convenient to open the mounting shell 3 later and remove the filter cylinder 4 inside.

[0057] Furthermore, two oil removal layers 13 are fixedly installed on the inner wall of the filter cartridge 4. The oil removal layers 13 are made of polylactic acid material and have through holes.

[0058] Specifically, the degreasing layer 13 can remove oil stains from the original liquid, thereby improving the purification effect of the liquid and reducing damage to the conveying mechanism and ceramic membrane 12.

[0059] Furthermore, the second conveying assembly 8 includes a second water pump 81 disposed on one side of the raw water pipe 1, the input end of the second water pump 81 is fixedly connected to a second connecting pipe 82, and the other end of the second connecting pipe 82 is connected to the first connecting pipe 10.

[0060] The output end of the second water pump 81 is fixedly connected to the third connecting pipe 83, and the filter shell 9 is fixedly installed on the third connecting pipe 83.

[0061] Specifically, the raw liquid can be transported to the filter housing 9 for filtration via the second water pump 81, the second connecting pipe 82, and the third connecting pipe 83.

[0062] Furthermore, the first delivery assembly 7 includes a first water pump 71 disposed on one side of the raw water pipe 1, the input end of the first water pump 71 is fixedly connected to an extraction pipe 72, and the other end of the second connecting pipe 82 is connected to the mounting housing 3.

[0063] The output end of the first water pump 71 is fixedly connected to the output pipe 73, and the other end of the output pipe 73 is connected to the second connecting pipe 82.

[0064] Specifically, the first water pump 71, the extraction pipe 72 and the output pipe 73 enable the raw liquid in the raw water pipe 1 to be delivered to the filter shell 9 when filtration is required.

[0065] Example 2

[0066] Based on Example 1, in this example: a magnet is provided on the inner side of the L-shaped groove 14, and the magnet is fixedly installed on one side inside the ring frame 63. A magnet is provided on one side of the snap-fit ​​block 15, and the magnet and the magnet attract each other.

[0067] The technical solution provided in this embodiment is as follows: when the filter cylinder 4 drives the snap-fit ​​block 15 to rotate to the inside of the L-shaped groove 14, the first magnet and the second magnet are attracted to each other, thereby improving the fixing effect and stability between the filter cylinder 4 and the ring frame 63.

[0068] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
