Description

Technical Field

[0001] This utility model relates to the technical field of filtration, and more specifically, to a filter element mechanism. Background Technology

[0002] The need for separation of mixed liquids is prevalent in practical applications. For example, the raw liquid is catalytic slurry, which is a byproduct of the catalytic process in oil refineries. Its density is as high as 1100 kg / m³ or more, its viscosity is greater than 1000 cst (kinematic viscosity at 100°C), and it contains about 1% solids, mainly aluminum and silicon oxides.

[0003] In existing technologies, solid-liquid separation of catalytic oil slurry, as described above, generally employs a centrifuge. This involves separating the solid and liquid within a high-speed rotating centrifuge drum using centrifugal force. For example, Chinese authorized invention patent CN201510159999.9 describes a filtration device and method. This filtration device utilizes centrifugal force to filter impurities from the liquid or solid-liquid mixture to be filtered, completing the filtration process and outputting the solution from the outlet.

[0004] However, the drawback of the aforementioned patent CN201510159999.9 is that the device is relatively simple and the filter material needs to be replaced frequently during use. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a filter element mechanism that has strong integrity, good filtration effect, and does not require frequent replacement of the filter medium.

[0006] The technical solution of this utility model is: a filter element mechanism, which includes a filter disc, a filter housing, and a liquid outlet pipe. The filter housing covers the outside of the filter disc, and the filter disc is fixedly connected to the filter housing. The bottom of the filter disc is connected to the liquid outlet pipe, and the filter disc is connected to the liquid outlet pipe.

[0007] The filter disc is disc-shaped and includes a filter disc support arranged in a 360-degree circle. The filter disc support is covered with a support sealing plate.

[0008] The filter disc also includes a filter media screen and an outlet fixing part. The filter media screen is located on both sides of the support sealing plate and has a disc-shaped structure.

[0009] The outlet fixing part is connected to the liquid outlet pipe.

[0010] In this invention, the raw liquid is poured into the filter housing. Under the drive of external force, the filter housing will swing, which will also cause the filter disc to swing. After the raw liquid passes through the filter medium mesh, it forms a purified liquid that enters the filter disc and is then output from the outlet pipe.

[0011] The filter disc of this invention is fixedly connected to the filter housing and moves synchronously, thus the filter element mechanism has strong integrity, with no scattered or redundant parts, and the stability of the filter element mechanism during movement is also strong. This invention uses a mesh filter medium for filtration, which has a good filtration effect and does not require frequent replacement of the filter medium.

[0012] Specifically, the filter media is a sintered metal mesh.

[0013] Furthermore, the filter element mechanism also includes an air inlet pipe, and the upper part of the filter disc is provided with an inlet fixing part. The air inlet pipe is connected to the inlet fixing part, and the filter disc is connected to the air inlet pipe.

[0014] Furthermore, both the inlet fixing part and the outlet fixing part are recessed groove structures facing the inside of the filter disc, and the air inlet pipe and the liquid outlet pipe are respectively inserted into the groove structure.

[0015] Preferably, the filter element mechanism further includes fixing bolts, and the filter disc has filter disc fixing parts on both sides along the disc-shaped direction. The fixing bolts pass through the filter housing and are inserted into the filter disc fixing parts to fix the filter disc to the filter housing.

[0016] Specifically, the filter disc fixing part is a groove structure that is recessed towards the inside of the filter disc.

[0017] Furthermore, the filter housing is also provided with an insulation layer.

[0018] Furthermore, an outer shell of the insulation layer is provided outside the insulation layer, and the fixing bolts fix the outer shell of the insulation layer to the filter housing.

[0019] Compared with the prior art, the advantages are: the filter disc of this utility model is fixedly connected to the filter housing and moves synchronously, so the filter element mechanism has a strong integrity, no scattered redundant parts, and the stability of the filter element mechanism during movement is also strong.

[0020] This invention uses a mesh filter medium for filtration, which has a good filtration effect and does not require frequent replacement of the filter medium.

[0021] This invention flushes the filter media by injecting compressed air into the air intake pipe, which saves costs compared to existing technologies that require replacing the filter media.

Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1-5 As shown, a filter element mechanism includes a filter disc 1, a filter housing 2, and a liquid outlet pipe 6. The filter housing 2 covers the outside of the filter disc 1, and the filter disc 1 is fixedly connected to the filter housing 2. The bottom of the filter disc 1 is connected to the liquid outlet pipe 6, and the filter disc 1 is connected to the liquid outlet pipe 6.

[0034] The filter disc 1 is disc-shaped and includes a filter disc support 11 arranged in a 360-degree circle. A support sealing plate 12 is provided on the filter disc support 11.

[0035] The filter disc 1 also includes a filter medium screen 13 and an outlet fixing part 16. The filter medium screen 13 is located on both sides of the support sealing plate 12 and has a disc-shaped structure. The outlet fixing part 16 is connected to the liquid outlet pipe 6.

[0036] In this embodiment, filter disc 1 is the core component of the filter element mechanism, serving to filter the raw liquid. The raw liquid in this embodiment is catalytic slurry, a byproduct of the catalytic process in oil refineries. Its density is over 1100 kg / m³, and its viscosity is greater than 1000 cst (kinematic viscosity at 100°C). It contains approximately 1% solids, primarily aluminum and silicon oxides. The presence of these solids significantly reduces the application value of the raw liquid. If the solids can be removed as required, the application value of the raw liquid can be increased by more than two times.

[0037] It should be noted that the raw liquid is filled into the filter housing 2 through an external interface (not shown in the figure). In addition, the filter disc support 11 arranged in a 360-degree surround makes the filter disc 1 have good overall strength.

[0038] Furthermore, a support sealing plate 12 is installed on the filter disc support 11, and the filter media mesh 13 is located on both sides of the support sealing plate 12. This arrangement prevents the raw liquid from entering the filter disc 1 from the 360-degree surrounding support sealing plate 12 (i.e., Figure 2 The support plate 12 in the middle ring is a closed structure. The raw liquid can only pass through the filter medium 13 to form a purified liquid that enters the filter plate 1 (e.g., Figure 6 (As indicated by the horizontal arrow).

[0039] The general principle is as follows: the raw liquid is poured into the filter housing 2. Under the drive of external force, the filter housing 2 will swing, which will also drive the filter disc 1 to swing. After the raw liquid passes through the filter medium mesh 13, it forms a clean liquid and enters the filter disc 1. The clean liquid is then output from the outlet pipe 6.

[0040] In this invention, the filter disc 1 is fixedly connected to the filter housing 2 and moves synchronously, thus the filter element mechanism has strong integrity, without any scattered or redundant parts, and the stability of the filter element mechanism during movement is also strong. This invention uses a mesh filter medium 13 for filtration, which has a good filtration effect and does not require frequent replacement of the filter medium.

[0041] Furthermore, the filter media 13 is a sintered metal mesh. In this embodiment, the sintered metal mesh is a new type of filter material made of multi-layered woven metal wire mesh through special lamination pressing and vacuum sintering processes, possessing high mechanical strength and overall rigidity. The mesh openings of each layer of the wire mesh are interwoven to form a uniform and ideal filter structure, which not only overcomes the shortcomings of ordinary metal wire mesh such as low strength, poor rigidity, and unstable mesh shape, but also allows for reasonable matching and design of the material's pore size, permeability, and strength characteristics. This results in excellent filtration accuracy, filtration impedance, mechanical strength, wear resistance, heat resistance, and processability, with comprehensive performance significantly superior to other types of filter materials such as sintered metal powder, ceramics, fibers, filter cloth, and filter paper.

[0042] Furthermore, the filter element mechanism also includes an air inlet pipe 5, and an inlet fixing part 15 is provided on the upper part of the filter disc 1. The air inlet pipe 5 is connected to the inlet fixing part 15, and the filter disc 1 is connected to the air inlet pipe 5. Both the inlet fixing part 15 and the outlet fixing part 16 are recessed groove structures facing the inside of the filter disc 1, and the air inlet pipe 5 and the liquid outlet pipe 6 are respectively inserted into the groove structures.

[0043] In this embodiment, during the filtration process, solids in the raw liquid become trapped on the filter media 13, forming a filter cake. The filter cake consists of the solid substances contained in the raw liquid that remain on the filter after the liquid has passed through it. Therefore, after the filter cartridge has been running for a period of time, the filter cake must be removed to restore the filtration effect. In this embodiment, compressed air is connected to the outside of the air inlet pipe 5. By injecting compressed air into the air inlet pipe 5, the filter media 13 is flushed, which saves costs compared to the prior art that requires replacing the filter media.

[0044] Specifically, the filter element mechanism also includes fixing bolts 7. Filter disc 1 has filter disc fixing parts 14 on both sides along its disc-shaped direction. The fixing bolts 7 pass through the filter housing 2 and are inserted into the filter disc fixing parts 14 to fix the filter disc 1 to the filter housing 2. The filter disc fixing parts 14 are recessed groove structures facing inwards towards the filter disc 1.

[0045] In this embodiment, the method of fixing the filter disc 1 to the filter housing 2 by passing the fixing bolt 7 through the filter housing 2 and inserting it into the filter disc fixing part 14 is simple and reliable. It can firmly fix the filter disc 1 to the filter housing 2 together, so that the filter disc 1 and the filter housing 2 can move synchronously.

[0046] Furthermore, an insulation layer 3 is provided around the filter housing 2. An outer insulation shell 4 is also provided outside the insulation layer 3, and fixing bolts 7 secure the outer insulation shell 4 to the filter housing 2. The insulation layer 3 helps to stabilize the temperature inside the filter housing 2. The outer insulation shell 4 serves to secure the insulation layer 3.

[0047] The overall working principle of this utility model is as follows:

[0048] Filtration process:

[0049] First, the raw liquid is poured into the filter housing 2 through an external interface (not shown in the figure). Driven by external force, the filter housing 2 will swing, causing the filter disc 1 to also swing.

[0050] Then, the original solution cannot enter the filter plate 1 from the 360-degree surrounding support sealing plate 12 (i.e. Figure 2 The middle ring of the support enclosure plate 12 is a closed structure. (For example...) Figure 6 As shown, the horizontal arrow indicates the direction of the raw liquid flow. The raw liquid can only pass through the filtration of the filter medium 13 to form a purified liquid that enters the filter plate 1. The purified liquid then flows out from the bottom of the filter plate 1. Figure 6 As indicated by the arrow at the bottom.

[0051] Rinsing process:

[0052] During the filtration process, solids in the raw liquid become trapped on the filter media 13, forming a filter cake. The filter cake consists of the solid substances from the raw liquid that remain on the filter after the liquid has passed through it. Therefore, after the filter cartridge has been running for a period of time, the filter cake must be removed to restore the filtration effect. In this embodiment, compressed air is connected to the outside of the air inlet pipe 5, and the filter media 13 is flushed by injecting compressed air into the air inlet pipe 5.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
