Abstract
The invention relates to the technical field of air filters, and discloses an air filter coarse strainer which comprises an outer frame and a pressing strip, wherein the outer frame is an angle aluminum alloy frame connected through welding, a filter screen is arranged in the outer frame, the pressing strip is arranged on the inner edge of the outer frame, and the pressing strip fixes the filter screen in the outer frame at the front end of the filter screen. The angle aluminum outer frame changes the frame structure, reduces the manufacturing difficulty, has low manufacturing cost and light weight, and meets the requirement of higher ventilation volume.
Description
Technical Field
The invention relates to the technical field of air filters, in particular to a coarse filter screen of an air filter.
Background
In the accessories of a 400km standard motor train unit, an air filter coarse strainer of a cooling unit is mainly used for the working conditions of large air intake, good interchangeability and small space requirement, and is used for the occasions of filtering large-particle air impurities on the side surface of a motor train body, severe working conditions and abundant ventilation quantity.
The traditional rough filter screen assembly of the cooling unit is mostly formed by welding an aluminum outer frame, and the back part of the traditional rough filter screen assembly is formed by riveting a pressing strip and is used for fixing a filter screen. The manufacturing method has high technological requirement and high manufacturing cost, and if the fan adopts an air suction type, the back of the fan is riveted to increase the risk of rivet failure.
Disclosure of Invention
The invention aims to solve the problems and provides a coarse filter screen of an air filter, which changes the structure of a frame body, reduces the manufacturing difficulty, has low manufacturing cost and light weight and meets the requirement of higher ventilation quantity.
The technical scheme adopted by the invention is as follows:
the utility model provides an air cleaner coarse strainer, characterized by, includes frame and layering, the frame sets up the filter screen for the angle aluminum alloy frame through welded connection in the frame, sets up the layering at the inward flange of frame, the layering fixes the filter screen in the frame at the front end of filter screen.
Furthermore, transverse or longitudinal additional pressing strips are arranged at a plurality of positions in the middle of the outer frame, and the additional pressing strips further fix the filter screen.
Further, a handle is arranged on the additional pressing strip.
The invention has the beneficial effects that:
through the improvement to the frame, greatly reduced the manufacturing degree of difficulty, angle aluminium frame not only cost is cheap weight reduction, and the change of leading filter screen satisfies the requirement of higher air volume in induced-draft fan simultaneously, greatly reduced the risk that the rivet became invalid.

Detailed Description
The following description will discuss an embodiment of a coarse filter screen of an air filter according to the present invention in detail with reference to the accompanying drawings.
Referring to the attached drawings 1, 2 and 3, the coarse filter screen of the air filter comprises an outer frame 1 and a pressing strip 2, wherein the outer frame 1 is an angle aluminum alloy frame connected through welding, a filter screen 3 is arranged in the outer frame 1, the pressing strip 2 is arranged at the inner edge of the outer frame 1, and the filter screen is fixed in the outer frame 1 at the front end of the filter screen 3 by the pressing strip 2. And transverse or longitudinal additional pressing strips 4 are arranged at a plurality of positions in the middle of the outer frame 1, and the additional pressing strips 4 further fix the filter screen 3. A handle 5 is arranged on the additional pressing strip 4.
During installation, the filter screen 3 is arranged in the outer frame 1, four sides of the filter screen are locked by the pressing strips 2 through fasteners, and the filter screen is further fixed through the additional pressing strip 4 in the middle. After the installation is finished, the installation is carried to the installation position through the handle 5. When the maintenance and the replacement are carried out, the additional pressing strip 4 and the pressing strip 2 are detached.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
Claims (3)
