Technical Field

The invention belongs to the technical field of filtration, and particularly relates to a high-pressure-resistant filter element.

Background

At present, various existing filters are easy to have the situations of insufficient pressure resistance, easy deformation and unchanged replacement due to the structure or material problems of filter elements. And most filter elements are difficult to clean, so that the filter elements are basically disposable products, and the waste is extremely large.

Disclosure of Invention

The invention aims to solve the technical problem that the sintered filter screen unit is used, so that the filter screen has higher strength, is not easy to deform, can be repeatedly used after being washed and cleaned, has a rod-shaped integral structure, has better pressure bearing performance, and is easy to disassemble and convenient to use.

In order to solve the technical problems, the invention adopts the technical scheme that: a high pressure resistant filter element comprises a guide pipe, a sintered filter screen unit and a locking nut; one end of the conduit is a connecting head, the other end of the conduit is provided with an external thread structure, and a plurality of gaps are formed in the conduit section between the connecting head and the external thread structure; sintering filter screen unit is the pipe structure, and the filter screen that the pipe wall formed for the sintering, sintering filter screen unit cover is established on the pipe section, lock nut twists the external screw thread is structural, sintering filter screen unit centre gripping is in lock nut with between the connecting head.

Above-mentioned high pressure resistant filter core, between sintering filter screen unit and lock nut, and all be provided with seal ring between sintering filter screen unit and the connector head.

In the high-pressure resistant filter element, the end of the guide pipe where the external thread structure is located is a sealing end, and the end where the connecting head is located is an opening end; the connector part is provided with external threads, and the end face of the outer side of the sealing end is provided with a groove along the diameter.

In the high-pressure resistant filter element, the transition part between the connecting head and the conduit section is of a shaft shoulder structure.

In the high-pressure resistant filter element, the plurality of gaps are divided into two rows on the curved surface of the conduit section, the plurality of gaps in each row of gaps are uniformly distributed along the extension direction of the conduit section, and each gap is formed by cutting along the radial direction of the conduit section.

Compared with the prior art, the invention has the following advantages: the sintered filter screen unit is used, so that the strength of the filter screen is higher, the filter screen is not easy to deform, the filter screen can be reused after being washed and cleaned, in addition, the integral structure is rod-shaped, the pressure bearing performance is better, and the sintered filter screen unit is easy to disassemble and convenient to use.

The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.

Detailed Description

As shown in fig. 1 and 2, the present invention comprises a guide tube, a sintered filter screen unit 1, and a locking nut 2; one end of the conduit is a connecting head part 4, the other end of the conduit is provided with an external thread structure, the conduit is integrally processed, a plurality of gaps 3 are arranged on a conduit section 5 between the connecting head part 4 and the external thread structure, and the plurality of gaps 3 are communicated with the inside of the conduit section 5; sintering filter screen unit 1 is the pipe structure, and the filter screen that the pipe wall formed for the sintering, 1 cover of sintering filter screen unit is established on pipe section 5, lock nut 2 is twisted the external screw thread is structural, 1 centre gripping of sintering filter screen unit is in lock nut 2 with between connecting head 4.

In this embodiment, sealing gaskets 6 are disposed between the sintered filter screen unit 1 and the locking nut 2, and between the sintered filter screen unit 1 and the connecting head 4. A stainless steel gasket 7 is arranged between the locking nut 2 and the sealing washer 6, and the guide pipe and the sintered filter screen unit 1 are made of stainless steel materials. Through setting up seal ring 6, can avoid sintering the gap department at filter screen unit 1 both ends, will need filterable liquid to leak into to guarantee the completeness of filter screen function. The sealing gasket 6 is a rubber sealing gasket 6.

In this embodiment, the end of the external thread structure of the conduit is a sealed end, and the end connected with the head 4 is an open end; the connecting head 4 is provided with an external thread, and the end face of the outer side of the sealing end is provided with a groove 8 along the diameter.

Through setting up recess 8, can be when connecting head 4 and installing in the filter cavity, conveniently be used for a word screwdriver to rotate recess 8, twist through recess 8 and revolve to whole pipe, have a better impetus of revolving. In practice, when the connection head 4 is installed in the filter, the connection head 4 is sleeved with a sealing gasket 6.

In this embodiment, the transition between the connecting head 4 and the conduit section 5 is a shoulder structure 9. The shoulder structure 9 is provided to mainly limit the sintered filter screen unit 1, and on the other hand, to limit the connection head 4 when mounted.

In this embodiment, the plurality of slits 3 are divided into two rows on the curved surface of the conduit section 5, the plurality of slits 3 in each row of slits 3 are uniformly arranged along the extending direction of the conduit section 5, and each slit 3 is formed by cutting along the radial direction of the conduit section 5. Through the design of the notch 3 adopting the structure, the integral torsion resistance of the conduit segment 5 is better, the conduit segment is not easy to deform, and on the other hand, filtered liquid can better enter the conduit.

As shown in figure 3, when the invention is used, the connecting head part 4 is installed in the filter containing cavity, when the invention is installed, the whole guide pipe is screwed through the groove 8, so that the connecting head part 4 is screwed in the filter containing cavity, then the liquid in the filter containing cavity is filtered into the guide pipe section 5 through the sintered filter screen unit 1, and finally the liquid is discharged from the connecting head part 4, and the filtration is finished.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiment according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
