Filter housing interface and filter

Abstract

This invention proposes an interface for a filter housing and a filter, including a main body and a sealing plate. The main body has openings at both ends that connect to the interior of the filter housing. The sealing plate is disposed in at least one of the openings. The sealing plate is integrally formed with the main body and can detach from the main body along a preset crack to open the opening. The preset crack consists of at least two intersecting straight lines, with both ends of each line extending radially from the main body to the edge of the sealing plate. By integrally forming the sealing plate with the interface body, material management is reduced while ensuring a sealing effect. At the same time, the sealing plate can split into several unit pieces through the preset crack, which not only ensures unobstructed flow of the main body when the equipment is in use, but also allows the unit pieces to reset and re-close the opening when the equipment is not in use.

Description

Technical Field

[0001] This invention relates to the field of ultrafiltration membrane technology, and more particularly to an interface for a filter housing and a filter. Background Technology

[0002] Currently, ultrafiltration membrane housings have two types of interface structures: Cobbling interfaces and union interfaces. Chinese patent CN107570013A discloses a fiber ultrafiltration membrane housing with interfaces at both ends. The union interface is sealed using a blind gasket, meaning a gasket is directly affixed to the port of the interface. The purpose of this gasket is to seal the filter housing assembly for easy storage and transportation, preventing external dust or other impurities from entering the filter housing assembly through the interface and causing adverse effects. During actual equipment assembly, the gasket is simply removed and discarded.

[0003] However, using blind gaskets to temporarily seal the filter housing has the following disadvantages:

[0004] Firstly, during equipment production and assembly, assemblers sometimes forget to attach the gaskets to the interfaces; moreover, filter housings and blind gaskets belong to different material categories, and the warehouse material management system needs to manage and store the gaskets, which increases the difficulty of material management.

[0005] Secondly, during equipment assembly, assemblers sometimes forget to remove the blind gasket from the interface, causing the interface to remain closed during equipment operation. This can lead to equipment malfunctions requiring shutdown for inspection. The blind gasket must be removed after identifying the problem before the equipment can be used again. Summary of the Invention

[0006] In view of this, the present invention proposes an interface for a filter housing and a filter, to solve the problem that currently, after the filter housing is manufactured, blind gaskets are often forgotten to be used to seal the interface.

[0007] The technical solution of the present invention is implemented as follows: The present invention provides an interface for a filter housing, including a main body, both ends of which are through to form openings and communicate with the interior of the filter housing; a sealing sheet is disposed in at least one of the openings; wherein, the sealing sheet is integrally formed with the main body, and the sealing sheet can detach from the main body along a preset crack and open the opening; the preset crack is at least two intersecting straight lines, and the two ends of each straight line extend radially along the main body to the edge of the sealing sheet.

[0008] Based on the above technical solutions, preferably, it also includes a protruding component, one end of which is disposed on the end face of the sealing sheet away from the interior of the filter housing and the other end of which extends in a direction away from the interior of the filter housing; wherein, the end of the protruding component away from the sealing sheet extends to the outside of the main body.

[0009] Even more ideally, all the straight lines intersect at the same point.

[0010] More preferably, the sealing sheet has a through hole in the center, and the extension direction of each straight line passes through the through hole; the sealing sheet is divided into several sheet units by a preset crack, one end of the sheet unit is connected to the inner wall of the opening and the other end extends toward the through hole; wherein, the end of the sheet unit facing the through hole can rotate around the connection part between the sheet unit and the inner wall of the opening; when the sheet units abut against each other to form a sealing sheet, the end of the protruding component can be set in the through hole and fix the sheet units.

[0011] More preferably, the protruding component includes a shaft, one end of which passes through the through hole and the other end which extends outward from the body in a direction away from the interior of the filter housing; a limiting plate fixed to the end of the shaft passing through the through hole; and a sleeve fitted onto the shaft and moving along the shaft; wherein the sleeve moves toward the limiting plate and clamps the ends of each unit facing the through hole between the sleeve and the limiting plate.

[0012] In a further preferred embodiment, the shaft is a screw rod, and the sleeve is threadedly connected to the shaft rod.

[0013] Even more preferably, the outer diameter of the sleeve is larger than the inner diameter of the through hole.

[0014] More preferably, the protruding component also includes an elastic strip, one end of which is fixed to the sleeve and the other end of which extends away from the shaft; wherein the end of the elastic strip away from the shaft extends to the outside of the main body and overlaps the outer wall of the main body.

[0015] Based on the above technical solutions, preferably, the cross-section of the sealing sheet along the main body axis is an isosceles triangle or an isosceles trapezoid.

[0016] On the other hand, the present invention also provides a filter whose filter housing adopts the above-described interface.

[0017] The filter housing interface and filter of the present invention have the following advantages over the prior art:

[0018] (1) The present invention integrates the sealing sheet and the interface body into one piece, which reduces the items of material management while ensuring the sealing effect. At the same time, the sealing sheet can be split into several pieces by pre-set cracks, which not only ensures the smooth flow of the main body when the equipment is in use, but also allows the pieces to reset to form a sealing sheet to close the opening again when the equipment is stopped.

[0019] (2) The present invention forms a foolproof design by setting a detachable protruding component on the sealing plate, which avoids the problem of users connecting the interface to external devices without removing the sealing plate.

[0020] (3) In the foolproof design of the protruding component, in addition to the protruding end of the shaft that is easy to identify by the eye, an elastic strip is also set on the sleeve to overlap the outer wall of the main body to obstruct the external equipment connecting parts that connect to the main body, thereby improving the foolproof effect.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1:

[0032] like Figure 1 As shown, combined with Figure 2 , Figure 3 and Figure 4 The filter housing interface of the present invention includes a main body 1 and a sealing piece 2.

[0033] The main body 1 has openings 101 at both ends, which are connected to the inside of the filter housing. The main body 1 of the interface is a hollow tubular structure, one end of which is fixed to the filter housing and connected to the inside of the filter housing, while the other end can be connected to a hose or other equipment connecting pipe.

[0034] A sealing piece 2 is disposed within at least one of the openings 101. The sealing piece 2 serves the same function as the blind gasket, sealing the opening 101 of the live interface body 1 to prevent external dust and contaminants from entering the filter housing through the opening 101 after production, thus preventing contamination or damage. However, in this embodiment, the sealing piece 2 is integrally formed with the body 1. Compared to using a blind gasket to cover the opening 101, the integral forming of the sealing piece 2 with the body 1 not only seals the opening 101 during filter housing production but also reduces material management items. Previously, there were two material items: the filter housing and the blind gasket; now there is only one material item: the filter housing, indirectly reducing the difficulty of material management.

[0035] The sealing piece 2 can detach from the main body 1 along a predetermined crack and open the opening 101; the predetermined crack is at least two intersecting straight lines a, each of which extends radially from the main body 1 to the edge of the sealing piece 2, thus allowing the sealing piece 2 to open like an umbrella. Preferably, all straight lines a intersect at the same point.

[0036] Specifically, the sealing plate 2 is divided into several plate units 21 by a pre-set crack. One end of each plate unit 21 is connected to the inner wall of the opening 101, and the other end extends toward the through hole 201. Therefore, the end of the plate unit 21 facing the through hole 201 can rotate around the connection between the plate unit 21 and the inner wall of the opening 101. The advantage of this is that the tail end of each plate unit 21 is still actually connected to the inner wall of the opening 101. Therefore, when the equipment is not in use or needs to be transported, each plate unit 21 can be rotated to recombine into the sealing plate 2 to close the opening 101.

[0037] It should be noted that since the sealing sheet 2 and the main body 1 are both integrally formed of metal material, when the sealing sheet 2 is torn, each piece unit 21 is bent and the opening 101 is opened, each piece unit 21 will not be straightened and reset during use.

[0038] Example 2:

[0039] Based on Example 1, such as Figure 1 As shown, combined with Figure 6 and Figure 7 It also includes prominent component 3.

[0040] The protruding component 3 has one end positioned on the end face of the sealing sheet 2 away from the interior of the filter housing, and the other end extending in a direction away from the interior of the filter housing; the end of the protruding component 3 away from the sealing sheet 2 extends to the outside of the main body 1. The protruding component 3 serves as a foolproof design, as its outer end protrudes from the main body 1, making it conspicuous and easy for the user to see, thus reminding the user whether they have forgotten to tear the sealing sheet 2.

[0041] Meanwhile, in order to ensure the sealing effect of the sealing plate 2 after straightening each piece unit 21 when the equipment is paused, a through hole 201 is provided in the center of the sealing plate 2, and the extension direction of each straight line a passes through the through hole 201.

[0042] When the individual unit 21 abuts against each other to form a closed piece 2, the end of the protruding component 3 can be placed in the through hole 201 and fix the individual unit 21.

[0043] Specifically, the protruding component 3 includes a shaft 31, a limiting plate 32, and a sleeve 33.

[0044] One end of the shaft 31 passes through the through hole 201, and the other end extends outward from the main body 1 in a direction away from the interior of the filter housing. The shaft 31 is a screw.

[0045] The limiting plate 32 is fixed at the end of the shaft 31 that passes through the through hole 201.

[0046] The sleeve 33 is fitted onto and screwed onto the shaft 31, and the sleeve 33 can move along the shaft 31.

[0047] Therefore, rotating the sleeve 33 moves it toward the limiting plate 32, thereby clamping the ends of each piece unit 21 facing the through hole 201 between the sleeve 33 and the limiting plate 32. The outer diameter of the sleeve 33 is larger than the inner diameter of the through hole 201 to ensure that the ends of all the piece units 21 can be clamped.

[0048] Example 3:

[0049] Based on Example 2, in order to improve the error prevention effect, such as Figure 1 As shown, combined with Figure 5 The prominent component 3 also includes an elastic strip 34.

[0050] One end of the elastic strip 34 is fixed to the sleeve 33, and the other end extends away from the shaft 31. The end of the elastic strip 34 away from the shaft 31 extends to the outside of the main body 1 and overlaps the outer wall of the main body 1, thereby obstructing the connection of the external equipment to the main body 1. The elastic strip 34 must be actively removed to allow the interface to connect to the external equipment, thus improving the foolproof effect.

[0051] Example 4:

[0052] Based on any one of embodiments one to three, the cross section of the sealing piece 2 along the axial direction of the main body 1 is an isosceles triangle or an isosceles trapezoid, so that the thickness of the part where the sealing piece 2 connects with the inner wall of the opening 101 is relatively thin, thereby allowing the sealing piece 2 to be torn off from the opening 101.

[0053] In addition, the method of making the pre-set crack in the sealing sheet 2 is similar to that of making a pull-tab lid.

[0054] Example 5:

[0055] The filter of the present invention has a filter housing using any one of the interfaces of Embodiments 1 to 4.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
