Wherein: the filter element is fixed and arranged in the shell by the upper support plate and the lower support plate; the filter element, the upper support plate and the lower support plate form a first cavity; a magnetic core is arranged in the first cavity, so that a magnetic field exists on the filter element; the shell, the filter element, the upper support plate and the lower support plate form a second cavity; the inlet of the filter is communicated with the first cavity of the shell; the outlet of the filter is communicated with the second cavity of the shell; when fluid flows in from the inlet of the shell, enters the first cavity through the round hole in the upper support plate, then flows through the filter element to enter the second cavity, and then flows out of the filter through the outlet, pollutants in the fluid are blocked by the filter element under the action of the magnetic field, and the fluid cannot flow out of the filter, so that the fluid cleaning control is realized. The embodiment of the invention can greatly improve the filtering effect of the filter.
Description
Technical Field
The present invention relates to the field of aerospace fluid system design, and more particularly to filters for fluid cleaning control.
Background
One of the methods of ensuring that the fluid medium is clean is to use a filter. The filter is capable of filtering contaminants from the fluid passing therethrough.
At present, the filter technology for coarse filtration is mature, but fine filtration requires a very fine filter screen, which increases the resistance of the fluid and deteriorates the flow condition.
Disclosure of Invention
In view of the above, the present invention provides a filter to solve at least one technical problem in the prior art.
The filter includes: casing, last extension board, filter core, extension board, magnetic core down, wherein:
the filter element is fixed and arranged in the shell by the upper support plate and the lower support plate;
the filter element, the upper support plate and the lower support plate form a first cavity;
a magnetic core is arranged in the first cavity, so that a magnetic field exists on the filter element;
the shell, the filter element, the upper support plate and the lower support plate form a second cavity;
the inlet of the filter is communicated with the first cavity of the shell;
the outlet of the filter is communicated with the second cavity of the shell;
when fluid flows in from the inlet of the shell, enters the first cavity through the round hole in the upper support plate, then flows through the filter element to enter the second cavity, and then flows out of the filter through the outlet, pollutants in the fluid are blocked by the filter element under the action of the magnetic field and cannot enter the second cavity.
Therefore, the embodiment of the invention can solve the problem that pollutants are retained in the filter and cannot flow out, and can realize fluid cleaning control. Because of the effect of the magnetic core, the filter element is surrounded by the magnetic field, so that the filtering effect is greatly improved, and fine filtering can be realized.

Fig. 1 is a schematic structural diagram of a filter according to an embodiment of the present invention.
The filter comprises a shell 1, an upper support plate 2, a filter element 3, a lower support plate 4 and a magnetic core 5.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Features and illustrative embodiments of various aspects of the invention are described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention. The present invention is in no way limited to any specific arrangement and method set forth below, but rather covers any improvements, substitutions and modifications in structure, method, and apparatus without departing from the spirit of the invention. In the drawings and the following description, well-known structures and techniques are not shown to avoid unnecessarily obscuring the present invention.
It should be noted that, in the case of conflict, the embodiments and features of the embodiments of the present invention may be combined with each other, and the respective embodiments may be mutually referred to and cited. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is a schematic structural diagram of a filter according to an embodiment of the present invention.
As shown in fig. 1, the filter may include: the filter comprises a shell 1, an upper supporting plate 2, a filter element 3, a lower supporting plate 4 and a magnetic core 5. The filter element 3 is fixed and installed in the housing 1 by the upper and lower support plates 2 and 4, and the magnetic core 5 is installed in the filter element 3.
The filter inlet communicates with the first chamber of the housing 1; the outlet is communicated with the second cavity of the shell 1, fluid flows in from the inlet of the shell 1, enters the first cavity through the round hole on the upper support plate 2, then flows through the filter element 3, enters the second cavity, and then flows out of the filter through the outlet. The contaminants in the fluid are blocked by the filter element 3 from entering the second chamber, and for this reason, the contaminants are retained in the filter and cannot flow out, achieving fluid cleaning control. Due to the magnetic core 5, the filter element 3 is surrounded by the magnetic field, so that the filtering effect is greatly improved.
In some embodiments, the filter may be mounted in a manner that includes the steps of:
a installing the magnetic core 5 in the filter element 3;
b, combining the filter element 3 with the upper support plate 2 and the lower support plate 4;
and c, putting the combined filter element 3, the upper support plate 2 and the lower support plate 4 into the shell 1.
It should be noted that the above flow operations can be combined to different degrees. For simplicity, the implementation of various combinations is not described again, and those skilled in the art can flexibly adjust the sequence of the above operation steps according to actual needs, or flexibly combine the above steps, and the like.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive various equivalent modifications or substitutions within the technical scope of the present invention, and these modifications or substitutions should be covered within the scope of the present invention.
