Abstract
The utility model relates to a removable steel lining filter core. The conventional steel lining filter element has the main defects that: the steel lining needs to be tightly attached to the filter membrane, burrs on the edge are easy to damage the filter membrane, the length of the steel lining is not easy to control, and the two ends of the steel lining can prop against the end cover after being lengthened, so that the filter element leakage is caused. The utility model discloses an exoskeleton sets up filter media and king-rod, its characterized in that in the exoskeleton the inside steel lining that sets up of filter media, the steel lining form hickey respectively in upper end and lower extreme, hickey with the hickey that forms matches on the filter core both ends. The utility model discloses can alternate inside conventional filter core and through screw thread and the supporting interface zonulae occludens in both ends, both avoided steel lining and filter membrane direct contact to cause the filter membrane damage, also avoided steel lining top jail end cover to cause the filter core to leak, but the design of steel lining recycle can reduce admittedly useless and practice thrift the cost.
Description
Technical Field
The utility model relates to a removable steel lining filter core.
Background
The conventional steel lining filter element has the main defects that: the steel lining needs to be tightly attached to the filter membrane, burrs on the edge are easy to damage the filter membrane, the length of the steel lining is not easy to control, and the two ends of the steel lining are lengthened to prop against the end cover, so that the filter element is leaked; the middle of the filter core is short, so that the filter core is not strong enough and is easy to deform; the steel lining can not be recycled, and the generated solid waste is high.
SUMMERY OF THE UTILITY MODEL
The utility model discloses shortcoming to prior art exists provides a removable steel lining filter core, has improved steel lining filter core structure, makes its ability recycle, avoids damaging the filter membrane, reduces admittedly useless and practice thrift the cost.
Therefore, the utility model adopts the following technical proposal: the utility model provides a removable steel lining filter core, includes the exoskeleton, sets up filter media and king-rod in the exoskeleton, its characterized in that the inside steel lining that sets up of filter media, the steel lining form the hickey respectively at upper end and lower extreme, the hickey with the supporting hickey that forms matches on the filter core both ends.
And a tetrafluoroethylene gasket is arranged between the threaded connector and the filter element end cover.
The outer diameter of the steel lining is 30 mm.
The two ends of the steel lining form M25 internal thread, and the two ends of the filter element form M25 external thread.
And the steel lining is also provided with a plurality of punching net pipes.
The utility model discloses make it can alternate inside conventional filter core and through screw thread and the supporting interface zonulae occludens in both ends, both avoided steel lining and filter membrane direct contact to cause the filter membrane damage, also avoided steel lining top jail end cover to cause the filter core to leak, but steel lining recycle's design can reduce solid useless and practice thrift the cost.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of the steel lining of the present invention.
Fig. 3 is a schematic view of the interface of the present invention, which takes a 222 triangular tip as an example.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The filter element with the replaceable steel lining as shown in the figures 1-3 comprises an outer framework 4, wherein a filter material 5 and a central rod 6 are arranged in the outer framework, the outer framework is externally connected with a triangular tip 1 through 222, a steel lining 7 is arranged in the filter material, the upper end and the lower end of the steel lining form a threaded connector 8 respectively, and the threaded connector is matched with threaded connectors 10 formed on the two ends of the filter element in a matched mode. And a tetrafluoroethylene gasket 2 is arranged between the threaded connector and the filter element end cover 3. The outer diameter of the steel lining is 30 mm. The two ends of the steel lining form M25 internal thread, and the two ends of the filter element form M25 external thread. The steel lining is also provided with a plurality of punching net pipes 9.
The utility model discloses change the steel lining external diameter for a short time, make it can alternate inside conventional filter core, the end that the welding of steel lining both ends contains interior silk thread, according to steel lining both ends thread size, the filter core interface is done to the die sinking again, and is supporting with steel lining both ends.
Specifically, the outer diameter of the steel lining is changed from 40mm to 30mm from the original outer diameter, M25 inner thread design is carried out on two ends of the steel lining, M25 outer thread design is carried out on a filter element interface, and a polytetrafluoroethylene gasket is adopted for sealing between the filter element and the interface matched with the two ends of the steel lining.
The utility model has the main advantages as follows:
1. the steel lining is not directly contacted with the filter membrane, so that the risk of leakage caused by damage to the filter membrane is avoided.
2. The steel lining is not welded inside the filter element, the length can be customized according to the length of the filter element, and the overall compressive strength of the filter element can be effectively improved while the leakage risk caused by the firm end cover is avoided.
3. The steel lining and the interface are connected through threads, so that the steel lining is convenient to disassemble and replace, the steel lining can be recycled, solid waste is reduced, and the cost is saved.
4. The interface adopts the tetrafluoro gasket to seal with filter core end cover contact surface, guarantees that the filter core does not have the leakage and chemical compatibility is not influenced.
The above description is only an example of the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
