Abstract

The utility model discloses a exempt from fastener enhancement mode and filter fossil fragments. The existing keel structure is mostly integral, the length of a single keel after processing is long, the strength is low, and the keel is easy to deform or break in transportation. The utility model discloses a split type structure is formed by upper cover, low head, solid fixed ring and the concatenation of many filter tubes. The utility model is formed by splicing a plurality of filter pipes through threads, and the place with large relative stress is an external thread, so that the connection strength is enhanced; all the openings are in arc transition, so that no stress concentration is ensured in the use process of the filter cloth, and the service life of the filter cloth is prolonged.

Description

Fastener-free reinforced filtering keel

Technical Field

The utility model belongs to the filtration equipment field, concretely relates to exempt from fastener enhancement mode and filter fossil fragments.

Background

The filtering keel is an important component in the filtering equipment and plays a role in supporting and fixing the filtering equipment core element, namely the filtering cloth. The filtering keel is convenient to install and maintain, so that the filtering effect and the service life of the whole set of filtering equipment are ensured. The existing keel structure is mostly integral, the processing is time-consuming, the blanking is recovered everywhere, and the environmental safety is influenced; the processed keel has a long single length and low strength, and is easy to deform or break in transportation; the junction is mostly the fossil fragments straight-bar and is the external screw thread with the upper cover, and the upper cover is the internal thread, and the use filters fossil fragments and receives liquid impact great, receives easy rupture of vibrations, high temperature factor's influence and pine to take off, influences the operation of whole equipment.

Disclosure of Invention

In order to compensate for the deficiencies of the prior art, the utility model provides a exempt from fastener enhancement mode to filter fossil fragments, convenient transportation and intensity are high.

The utility model discloses the technical scheme who adopts does:

the fastener-free reinforced filter keel comprises an upper end enclosure, a lower end enclosure, two fixing rings and a plurality of filter pipes; the interior of the upper end enclosure is of a hollow structure, the appearance of the upper end enclosure is of a stepped cylindrical shape, and one end of the upper end enclosure is provided with an external thread; the fixing ring is in a ring shape; the filter pipe is in a hollow stepped cylinder shape, one end of the filter pipe is provided with an external thread, the other end of the filter pipe is provided with an internal thread, and the outer wall of the filter pipe is provided with a plurality of through holes; the lower end enclosure is in a stepped cylindrical shape, one end of the lower end enclosure is open, the other end of the lower end enclosure is closed, and the open end is provided with internal threads; the external thread end of the upper end enclosure is arranged in the inner hole of the fixing ring and is connected with the internal thread end of the filter pipe; the plurality of filter pipes are connected through threads at two ends; the external thread end of the end section filter pipe is arranged in the inner hole of the other fixing ring and is connected with the internal thread end of the lower seal head;

the utility model discloses all spare parts trompil departments are the fillet transition.

The utility model has the advantages that:

1) the utility model adopts a split structure and is formed by splicing an upper end socket, a lower end socket and a plurality of filter pipes, thereby being convenient for transportation;

2) the utility model has simple processing technology, convenient assembly and no unnecessary waste;

3) compared with the prior filter pipe which is a single pipe, the utility model is formed by splicing a plurality of filter pipes through threads, and places with large relative stress are external threads, so that the connection strength is enhanced, and the problems of corrosion of a clamp, loosening of a binding belt due to heating and the like caused by vibration, high temperature and the like in the use of the prior filter keel are solved;

4) the utility model discloses the whole circular arc transition of all trompil departments ensures that no stress concentrates in the filter cloth use, extension filter cloth life.

Detailed Description

The present invention will be described in detail with reference to the following embodiments.

Fig. 1 is an overall structure diagram of the embodiment of the present invention. As shown in fig. 1, the filter keel comprises an upper seal head 1, a lower seal head 4, two fixing rings 2 and a filter pipe 3; the interior of the upper end enclosure 1 is of a hollow ladder structure, the appearance of the upper end enclosure is of a ladder cylindrical shape, one end of the upper end enclosure is provided with external threads, and the other end of the upper end enclosure is provided with 3 circular through holes along the axis direction; the fixed ring 2 is in a ring shape; the filter pipe 3 is in a hollow stepped cylindrical shape, one end of the filter pipe is provided with an external thread, the other end of the filter pipe is provided with an internal thread, and the outer wall of the filter pipe is provided with a plurality of strip-shaped through holes; the lower end enclosure 4 is in a stepped cylindrical shape, one end of the lower end enclosure is open, the other end of the lower end enclosure is closed, and the open end is provided with internal threads; the external thread end of the upper seal head 1 is arranged in the inner hole of the fixed ring 2 and is connected with the internal thread end of the filter pipe 3; the external thread end of the filter pipe 3 is arranged in the inner hole of the other fixed ring 2 and is connected with the internal thread end of the lower seal head 4. And all parts are provided with holes in a fillet transition mode.

When the filter is used, the filter cloth is sleeved on the straight rod part of the assembled filter keel, the end parts of the filter cloth respectively penetrate through the inner holes of the two fixing rings connected with the upper seal head and the lower seal head, the upper seal head and the lower seal head are connected with the filter pipe through threads at the two ends, and the filter cloth is fastened on the filter keel; the filtering keel provided with the filter cloth is connected with the filtering equipment through 3 circular through holes on the upper end enclosure by using anti-corrosion bolts. The number of the filter pipes can be spliced according to actual requirements.

In the description of the present invention, unless expressly stated or limited otherwise, the terms "disposed," "mounted," "connected," and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral part; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship.
