Technical Field

The invention relates to the field of filter element purification equipment, in particular to a composite compression-resistant filter element end cover for a multilayer filter element.

Background

Filtration purification is one of the current common applications, and as environmental pollution gradually deepens, more and more people begin to focus on filtration purification, such as water purification, air purification, etc., and these purification processes often need to use the filter core, and the filter core is a filter screen with filtration pore, and the mixture gets into the inside of filter core, and what comes out from the filter core side is the liquid after the filtration purification, because the filter core is inside to be hollow, so once being crushed or warp, can serious influence subsequent filterable effect.

Therefore, the inventor aims to invent a pressure-resistant filter element end cover for a multilayer filter element, aiming at solving the problem that the filter element is easy to collapse or deform.

Disclosure of Invention

To overcome the above disadvantages, the present invention provides a pressure-resistant end cap for a multi-layer filter element.

In order to achieve the above purposes, the invention adopts the technical scheme that: the utility model provides a resistance to compression formula filter core end cover for multilayer filter core, includes the filter core, the filter core is enclosed into the cylinder by the filter screen, just the inside of cylinder is cavity the tip of filter core is provided with the end cover, the end cover is formed by the steel sheet pressfitting, including the base plate the center of base plate sets up interior plate washer, the outside edge of base plate sets up the fixed plate, just interior plate washer and fixed plate all are the annular setting, and are located the homonymy of base plate, and annular just can be fixed with the outward flange of filter core in the fixed plate, and annular interior plate washer just can support with the inward flange of filter core and lean on.

Preferably, the fixing plate of the end cover is provided with an internal thread, and the internal thread can be matched with the outer side of the filter element to fix the filter element. The setting of screw thread is a relatively safer fixed setting in fact, can guarantee the stability when the use of filter core.

Preferably, an inner supporting piece is arranged on an inner baffle plate of the end cover, the inner supporting piece can be an external thread or a sealing ring, and the inner supporting piece is arranged on the outer side of the inner baffle plate. The support of the inner support piece to the inner layer filter screen is ensured.

Preferably, the length of the inner baffle is greater than that of the fixed plate, a plurality of inner supporting pieces are arranged on the inner baffle and are uniformly distributed, and when the inner baffle abuts against the inner wall of the filter element, the end part of the filter cloth is arranged between the inner baffle and the inner wall of the filter element, and the filter cloth can be kept flat. Through with interior shelves extension, guaranteed interior shelves to the inside support of filter core, even when the filter core outside takes place the extrusion, inside also has suitable power to support to also have the support to the filter cloth and guarantee leveling all the time of filter cloth.

Preferably, the filter core comprises at least two-layer filter screen, and at least two-layer the filtration pore crisscross distribution of filter screen is simultaneously at least two-layer set up the filter cloth between the filter screen, the material of filter cloth adopts synthetic fiber such as dacron. If the filter screen has three or more layers, the selection of synthetic fiber materials such as filter cloth and terylene is needed to be distributed between two adjacent layers, which is the stable chemical property of fully considering the wear-resisting property and not reacting with the filtrate.

Preferably, the central position of the end cover is a through hole, the through hole is communicated with a hollow structure inside the filter element, and the through hole is surrounded by the inner baffle. Due to the circular filter element, the feed of filtrate is also ensured if the filtrate enters from the middle of the filter element and exits from the outside of the filter element.

The pressure-resistant filter element end cover for the multilayer filter element has the advantages that the inner baffle plate supports the filter element, so that the pressure-resistant effect is achieved, the filter element is prevented from being seriously deformed when external force or high-pressure filtrate is applied, the filtering effect is not influenced, and the service life of the filter element is prolonged.
