Abstract
The utility model discloses a filter stick relating a filter element, which aims at providing a filter stick having good sealing property and simple structure. The technique proposal of the utility model is that the filter stick comprises a framework, a screw cap and a plugging cap, wherein one end hole of the screw cap is matched with the framework body, a brazing seam is arranged between the screw cap and the framework, the other end of the screw cap is provided with inner threads which are matched with external threads on a pipe body of the other end of the framework, and an anti-loose screw cap is arranged on the framework between filter materials and the screw cap. The filter stick is used in a filter in a device in metallurgical and chemical industries.
Description
Technical field:
The utility model relates to a kind of filter element, particularly a kind of filter stick.
Background technology:
Existing filter stick (filter element), form by skeleton, filter medium, nut and " O " RunddichtringO, skeleton is the pipe that a plurality of terminations are provided with screw thread and cannelure, and the skeleton that is provided with filter medium (filter material) makes the distortion of flexible " O " shape sealing ring realize sealing by nut when assembling connects, this " O " shape sealing ring is in assembling process, because the rotation of nut often makes the sealing circle body break, and seal failure, in addition, structure is complicated, the processing cost height.
Summary of the invention:
The purpose of this utility model provides a kind of good seal performance and filter stick simple in structure.The technical solution of the utility model is, a kind of filter stick, comprise skeleton, nut and blocking cap, it is characterized in that: a stomidium and the skeleton body of screw cap hole match, between screw cap hole and the skeleton body weld seam is arranged, the external screw thread that the other end of screw cap hole is provided with on the other end body of internal thread and skeleton matches, and is provided with anti-loosening nut on the skeleton body between filter material and the nut.The utility model has good seal performance and advantage of simple structure compared with the prior art.
Description of drawings:
Accompanying drawing is the structural representation of the utility model filter stick.
The specific embodiment:
In conjunction with above-mentioned accompanying drawing the utility model is elaborated, filter stick of the present utility model is identical with existing skeleton, filter material and nut, different is that sealing ring is not set, change has been done in method of attachment, the internal thread that one end of segmentation filter stick is provided with external screw thread and nut one end matches, and the unthreaded hole of its other end pipe diameter and the above-mentioned nut other end matches.
Assembly method of the present utility model is, at first be enclosed within the unthreaded hole end of nut on the plain end of a skeleton 1 and make the end face of pipe contact the back with step end face in nut 3 holes and form girth joint 4 at the body of the place, chamfering aperture of nut and segmentation skeleton with welding method it is linked into an integrated entity, again filter material 5 is sleeved on the body of the skeleton that is welded with nut, with anti-loosening nut 2 filter material is compressed, its elasticity is regulated by designing requirement or according to filtering requirement, the thread segment that installs the segmentation skeleton of filter material is screwed in the screwed hole of the WELD NUTS on another segmentation skeleton and till screwing, on the screw thread of the skeleton body of outer end, screw on blocking cap 6 at last and screw.This filter stick has replaced " O " shape sealing ring with the nut of welding, has avoided causing because of breaking of sealing ring the problem of seal failure.
Claims (1)
1, a kind of filter stick, comprise skeleton, nut and blocking cap, it is characterized in that: a stomidium and the skeleton body of screw cap hole match, between screw cap hole and the skeleton body weld seam is arranged, the external screw thread that the other end of screw cap hole is provided with on the other end body of internal thread and skeleton matches, and is provided with anti-loosening nut on the skeleton body between filter material and the nut.
