Conical filter and pipeline

Technical Field

The application belongs to the technical field of filter devices, and particularly relates to a conical filter and a pipeline.

Background

In the fields of metallurgy, chemical industry and the like, before the equipment is formally started, the residual solid impurities in the pipeline are required to be washed, and the solid impurities are filtered and removed by a conical filter arranged on the pipeline, so that the equipment, a valve, an instrument and the like are prevented from being damaged due to the influence of the solid impurities.

The conical filter is installed between two adjacent flanges, the mounting plate of the conical filter is clamped through the end faces of the two adjacent flanges, and sealing elements are further arranged on two sides of the mounting plate respectively for preventing fluid in a pipeline from leaking from the mounting plate, so that the risk of fluid leakage from the mounting plate is reduced. The gap between the end faces of two adjacent flanges is the sum of the thickness of the mounting plate and the thickness of the two sealing elements.

The conical filter is only used temporarily before the equipment is started, the conical filter is required to be removed after the pipeline is cleaned, and the conical filter is not used when the equipment is in normal operation. After the conical filter is removed, a backing ring is required to be arranged to make up the gap left by the mounting plate of the conical filter, and a sealing gasket is also required to be arranged on each of the two sides of the backing ring, so that the gap left by the sealing elements on the two sides of the mounting plate is made up, and the backing ring is in sealing fit with the flange surface through the sealing elements. This results in a higher number of gaskets for sealing the gap between the end faces of adjacent two flanges, which increases the risk of leakage of the pipe.

Since at least part of the orthographic projection of the mounting plate coincides with the orthographic projection of the annular seal in the direction perpendicular to the axis of the conical filter, the annular seal and the mounting plate together occupy less space, so that after removal of the conical filter, the gap between the end faces of two adjacent connecting flanges is reduced compared to the background art, and a gasket can be used between the two connecting flanges; or a backing ring and a sealing gasket are selected and arranged between the two adjacent connecting flanges, so that a gap between the two adjacent connecting flanges is sealed.

The mounting plate 100 may be a ring-shaped member, such as a circular ring, and one end of the filter screen 210 may be connected to the inner circumferential surface of the mounting plate 100; alternatively, the filter screen 210 may be disposed on the first surface or the second surface of the mounting plate 100. In addition, the shape of the mounting plate 100 is not limited in this application, and for example, the mounting plate 100 may be annular, sector-annular, or the like. Further, the conical filter further comprises a pore plate 220, the pore plate 220 is wrapped by the filter screen 210, the pore plate 220 can support the filter screen 210, the filter screen 210 can be connected with the mounting plate 100 through the pore plate 220, and the shapes of the filter screen 210 and the pore plate 220 can be matched.

The annular seal 300 is provided on the mounting plate 100, at least part of the orthographic projection of the mounting plate 100 coincides with the orthographic projection of the annular seal 300 in a direction perpendicular to the axis of the conical filter (the direction in which the axis is in is the direction indicated by the arrow line in fig. 1 to 4 and 6), the mounting plate 100 has a first face and a second face disposed opposite to each other in the axial direction of the conical filter, and the annular seal 300 has a first sealing face and a second sealing face disposed opposite to each other, the first sealing face being disposed protruding from the first face, and the second sealing face being disposed protruding from the second face. In this embodiment, the first sealing surface of the annular sealing member 300 protrudes from the first surface, the second sealing surface protrudes from the second surface, and when the conical filter is installed between two adjacent connecting flanges, the first sealing surface and the second sealing surface can be respectively in sealing fit with the two connecting flanges, so that fluid in the pipeline is prevented from leaking from the mounting plate 100. Since at least part of the orthographic projection of the mounting plate 100 coincides with the orthographic projection of the annular seal 300 in a direction perpendicular to the axis of the conical filter, the annular seal 300 and the mounting plate 100 together occupy less space, so that when the conical filter is removed, the gap between the end faces of two adjacent connecting flanges is reduced compared to the background art, and a gasket can be used between the two connecting flanges; or a backing ring and a sealing gasket are selected and arranged between the two adjacent connecting flanges, so that a gap between the two adjacent connecting flanges is sealed.

In an alternative embodiment, the mounting plate 100 is provided with an annular through hole extending through the mounting plate 100 in the direction of the axis of the conical filter, and a portion of the annular seal 300 is provided in the annular through hole, that is, in a direction perpendicular to the axis of the conical filter, the orthographic projection of the mounting plate 100 is all coincident with the orthographic projection of the annular seal 300. The annular sealing member 300 and the mounting plate 100 overlap more, and the annular sealing member 300 can be embedded in the annular through hole, so that the connection strength between the annular sealing member 300 and the mounting plate 100 is high, and the annular sealing member 300 is not easy to separate from the mounting plate 100. Alternatively, the width of the annular seal 300 may be slightly greater than the width of the annular through hole, such that the annular seal 300 may be pressed into the annular through hole, thereby securing the annular seal 300 to the mounting plate 100.

In the above embodiment, the annular seal 300 is a one-piece member and has both the first sealing surface and the second sealing surface, so that the embodiment can simplify the mounting operation of the annular seal 300.

Since at least part of the orthographic projection of the mounting plate 100 coincides with the orthographic projection of the annular seal 300 in a direction perpendicular to the axis of the conical filter, the annular seal 300 and the mounting plate 100 together occupy less space, so that when the conical filter is removed, the gap between the end faces of two adjacent connecting flanges is reduced compared to the background art, and a gasket can be used between the two connecting flanges; or a backing ring and a sealing gasket are selected and arranged between the two adjacent connecting flanges, so that a gap between the two adjacent connecting flanges is sealed.
