Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a filter mounting frame, and particularly to an air filter mounting frame in which a filter element can be taken in and out from the side of the mounting frame.

[Conventional technology]

In filter units in which a filter element is mounted on a filter mounting frame, there are two types: one type in which the filter element is inserted and removed from the front surface (inflow surface) of the mounting frame, and the other type in which the filter element is inserted and removed from the mounting frame.

When attaching the filter element to the mounting frame, if a gap is created between the filter element and the inner surface of the mounting frame, the filtration function will be impaired. be done.

[The problem that the idea attempts to solve]

Mounting the filter element in a pressed state against the support frame on the inner surface of the mounting frame can be easily realized with a structure in which the filter element is taken in and out from the front surface of the mounting frame. However, with structures in which loading and unloading is carried out from the side of the mounting frame, there is usually no space available at the front. In this case, it is difficult to press the filter element against the support frame because it is not possible to insert one's hand deep into the mounting frame from the side surface thereof.

Therefore, in view of these problems of the prior art, this invention has been developed to provide a filter mounting structure that allows the filter element to be easily and securely pressed against the support frame in a filter unit in which the filter element is inserted and removed from the side. The purpose is to provide a framework.

[Means to solve the problem]

In order to achieve the above object, the filter mounting frame of this invention has the front and rear sides open, an opening for the filter element on the side, an opening/closing door at the opening, and a filter mounting frame that faces both the upper and lower sides. In a filter mounting frame to which support members of the elements are respectively attached, an adjustment member that is slidable in the front and back direction is fitted to the front support ridge of the support member, and an elastic body that presses against the front surface of the filter element is attached to the adjustment member. It is structured as follows.

[Effect]

When the filter element is inserted from the side of the mounting frame, the elastic body of the adjustment member on the front side is pressed against the upper and lower parts of the filter element, and the rear surface is pressed against the rear support flange.

〔Example〕

The filter mounting frame 1 of the embodiment shown in the drawings constitutes a rectangular frame as a whole, and openings 2 and 3 are provided on the front and rear surfaces, respectively, with the front opening 2 facing upstream and the rear surface facing upward. It is designed to be installed with the opening 3 facing downstream.

An inlet/outlet 6 for the main filter element 4 and pre-filter element 5 is provided on one side of the mounting frame 1, and a door 7, which can be opened and closed freely, is attached to the inlet/outlet 6 with a hinge 8, and is locked with a lock 9. It's getting old.

Mounting bases 1 are installed on both the upper and lower sides of the mounting frame 1.
0 is fixed, and a support rail 1 of the prefilter element 5 is mounted on the mounting base 10 on the side of the front opening twice.
1 is attached, and the support member 12 of the main filter element 4 is attached to the rear of the support rail 11.

The support member 12 has a front support flange 13 bent inward in a U-shape and a rear support flange 14, and two support rails 15 are provided between both the support flange 13 and 14. It is something that

An adjustment member 16 having a U-shaped cross section is inserted into the front support flange 13 over its entire length so as to be slidable in the front-rear direction. This adjustment member 16 is inserted so that the U-shaped open surface faces inside the support flange 13. Adjustment bolts 17 are fixed near both ends of the adjustment member 16 (see FIG. 3),
A coil spring 18 is fitted to each adjustment bolt 17, and the legs of the bolt 17 are loosely fitted to the supporting flange 13, and a nut 19 is fitted to the protruding end. By operating the nut 19, the adjustment member 16 is positioned in the front-rear direction.

Further, on the rear end surface of the adjustment member 16, that is, the surface facing the main filter element 4, a curved plate spring 20 protruding toward the main filter element 4 side is attached near each bolt 17.
with the required spring force.

On the other hand, seal members 21 made of rubber or the like are attached to the upper and lower edges of the rear surface of the main filter element 4.
The sealing member 21 is brought into contact with the rear support flange 14.

In addition, as shown in FIG. 4, the rear support flange 14
The sealing member 22 may also be attached to the main filter element 4 so as to be brought into contact with the sealing member 21 on the main filter element 4 side.

Since the filter mounting frame of the embodiment of this invention is as described above, the side door 7 is opened and the pre-filter element 5 is inserted into its support rail 11, and the main filter element 4 is inserted into the support member 12. do. When the door 7 is closed, the left and right sides of each filter element 5, 4 are brought into close contact between the inner surface of the door 7 and the inner surface of the mounting frame 1, and the main filter element 4 is sealed by the spring force of the leaf spring 20. The member 21 is pressed against the rear support flange 14 and seals.

In addition, for main filter elements 4 having different widths, the adjustment member 16 is moved back and forth by operating the nut 19. Thereby, a constant pressing force can be applied to the main filter element 4 regardless of the difference in width.

[Effect of idea]

As described above, in a filter mounting frame in which the filter element is inserted and removed from the side, an adjustment member is fitted to the front support flange of the filter element support member, and the elasticity of a leaf spring or the like attached to the adjustment member is Since the filter element is pressed against the rear support flange by the body, it is possible to achieve close contact with the rear support flange by simply inserting the filter element from the side. Furthermore, differences in the width of the filter elements can be easily dealt with by adjusting the position of the adjustment member.
