Abstract

The utility model relates to mechanical engineering, in particular to engine building, and can be used in the manufacture of filter elements. The filter element contains a spiral frame with a filter layer and end discs. The frame is made in the form of a spirally twisted strip, the edges of which are fastened with a locking joint, which is reinforced with a bulge. The technical result is the ability of the filter element to withstand heavy loads during operation by increasing the strength of the frame in the longitudinal and transverse directions. 3 ill.

Description

The utility model relates to mechanical engineering, in particular to engine building, and is intended for the manufacture of filter elements.

The closest in technical essence is a filter element with spiral frames (RU 112283, publ. 10.01.2012 Bull. No. 1), including the outer and inner frames, the filter layer and end discs, the outer and inner frames are made by spiral laying. The disadvantage of this design of the filter element is the insufficient strength of the lock connection.

The technical problems to be solved by the utility model are to develop a rigid filter element capable of maintaining its shape and dimensions during operation, to reduce the cost, to simplify the manufacturing process, and to improve its performance properties due to the fact that the manufacturing process excludes welding and the use of additional fasteners.

These tasks are solved due to the fact that the filter element with a spiral frame includes a filter layer and end discs, the frame is made by spiral laying from a strip, the edges of which are fastened with a lock joint, which is strengthened by peening.

The technical result provided by the above set of features is the ability to withstand heavy loads, and thereby increases the strength of the frame in the longitudinal and transverse directions.

The essence of the utility model is illustrated by drawings, which show:

in fig. 1 - general view of the filter element in section,

figure 2 - puklevka castle connection,

in fig. 3 - screw frame,

where 1 - frame;

2 - filter layer;

3 - end disk;

4 - lock connection;

5 - puklevka.

The filter element contains a spiral frame 1, a filter layer 2. There are end discs 3 on top and bottom of the filter element.

The frame is made by means of spiral laying from expanded strip or from a continuous strip with perforated holes, the edges of which are left intact. The edges of the strip are connected to each other by a lock joint (sealing seam) 4. The lock joint is reinforced with a bulge 5.

Punching is performed by the method of plastic deformation of metal elements using special equipment, as a result of which thin layers of metal are connected without the use of additional fasteners or welding. Puklevka is carried out with a certain step, depending on the design requirements and the size of the filter element frame.

The specified method of connecting metal elements allows them to be securely fastened at the lock joint without the use of welding and fasteners, which increases the strength of the frame and enables the filter element to withstand heavy loads during operation.

The proposed design of the filter element frame allows you to automate the production of the filter, reduce the amount of waste, allows you to use equipment of less power in the manufacturing process, which in turn allows you to use smaller areas for the production process. Automation of the manufacturing process makes it possible to obtain high quality products with precise geometric parameters.

Claims (1)

A filter element containing a frame with a filter layer and end discs, wherein the frame is made in the form of a spirally wound strip, the edges of which are connected by a lock connection, characterized in that the layers of the spirally wound strip at the lock connection are fastened with a bulge.
