[0020] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed description is given in conjunction with the embodiments.

[0021] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0022] Please refer to Figure 1-Figure 4 A pull-out filter element support device comprises a support frame 1, an outer shell 2, and a sealing top plate 3; the support frame 1 is installed inside the outer shell 2, the length, height, and thickness of the support frame 1 extend along the X direction, the Y direction, and the Z direction respectively, the support frame 1 is divided into N columns along the X direction, and is divided into M rows along the Y direction, and the whole is composed of N*M unit fixing frames 11, wherein N≥2, M≥2; a baffle 12 is arranged on the edge of the unit fixing frame 11 along the X direction, and the baffle 12 is perpendicular to the XZ plane and A pull-out track 13 extending along the X direction is formed, and the pull-out track 13 extends from the 1st column to the Nth column. A small filter element is placed in the mth row of the support frame 1 from the YZ surface, where 1≤m≤M, and is pushed inward to the nth column, where 1≤n≤N. A pull-out opening 21 is provided on the YZ side of the outer shell 2, and the pull-out opening 21 is opposite to the YZ surface of the support frame 1. The small filter element is pushed into the support frame 1 from the pull-out opening 21. The sealing top plate 3 is installed in the pull-out opening 21 and seals the pull-out opening 21.

[0023] A pull-out installation method using any of the above support frames 1 comprises the following steps: S1. Device construction; install the pull-out filter element support device inside the outer shell 2, with the pull-out opening 21 facing the YZ surface of the filter support frame 1; S2, install the filter element; send the filter element from the pull-out opening 21 to the support frame 1 inside the outer shell 2, select the mth row of the support frame 1, place the filter element, and push it inward along the pull-out track 13 until it reaches the designated position in the nth column; S3, repeat the operation of S2, and install all the filter elements one by one on the support frame 1; S4, installing the sealing top plate 3 to seal the drawer opening 21.

[0024] The filter elements inside the current filter device are not well arranged and fixed, but the present invention utilizes the support frame 1 to integrate all the filter elements on the frame, arrange them tightly and neatly, and can install more filter elements in a limited space. The presence of the unit fixing frame 11 and the baffle 12 in the support frame 1 makes the installation of the filter elements more secure and not easy to detach from the frame. The overall stability of the filter is higher and the filtering effect is better.

[0025] The existing filter device is usually a front-mounted structure, with an installation door set on the XY plane. Since there are M rows and N columns of filter elements on the XY plane that need to be installed in sequence, they are additionally fixed with devices such as locks. Therefore, a large area of ​​installation space is usually required on the outside to be sufficient to install the door switch, and a large area of ​​installation space is also required on the inside to be sufficient for the installer to enter the outer shell 2 and move the position. The pull-out support device and installation method of the present invention form a pull-out track 13 extending along the X direction for each row of the support frame 1Y direction, with a total of M columns of tracks, baffles 12 are provided on both sides of the track, and the entrance of the track is directly opposite to the pull-out opening 21 opened on the outer shell 2. The installation worker only needs to stand next to the pull-out opening 21, select one of the M columns of tracks, put the filter element from the pull-out opening 21 into the column of tracks of the fixed frame, and then push it inward along the pull-out track to a certain row in the N rows of the column. All filter elements are installed according to the above method, which is convenient and fast, and all operations can be completed by just standing in front of the pull-out opening 21. The installation worker no longer needs to enter the outer shell 2, nor does the installation worker need to move his own position according to the installation position of the filter element. The installation door is converted into a small-area pull-out opening 21, and the product volume of the filter device itself is reduced, and the space required for installation is also greatly reduced. The product is miniaturized and lightweight, and is more suitable for use in small factories and workshops.

[0026] In one embodiment, M=2, N=2, then the support frame 1 can install a total of 4 aluminum cores. When installing the filter element, the installer only needs to open the sealing top plate 3, first send the first filter element into the first column entrance from the pull-out entrance, and then push it to the first row along the pull-out track 13 of the first column, so the filter element is successfully installed in the first column and the first row; the second filter element is continued to be placed at the entrance of the first column, and then pushed to the second row along the pull-out track 13 of the first column, so the filter element is successfully installed next to the first filter element in the first column and the second row; similarly, the third filter element is placed at the entrance of the pull-out track 13 of the second column and pushed to the first row, and the fourth filter element is placed at the entrance of the pull-out track 13 of the second column and pushed to the second row. It can be clearly seen that when the installer installs the filter elements of the same column, the position of the installation entrance is the same. When installing filter elements of different columns, it is only necessary to change the height, thereby changing the pull-out track 13. In addition, the present invention does not limit the installation order of filter elements in different columns, that is, in the absence of special installation requirements, the installer can select the pull-out rails 13 in different columns for installation in any order.

[0027] The presence of the pull-out rail 13 of the present invention makes the installation of each column of filter elements extremely fast and convenient. If the pull-out rail 13 is long, the installer can use auxiliary tools, such as a long rod that can be fixed on the filter element to assist in pulling and pushing the filter element. When the filter element needs to be replaced at a later stage, it is only necessary to open the sealing top plate 3, and all the filter elements can be quickly taken out for maintenance or replacement using the pull-out opening 21.

[0028] The pull-out opening 21 of the present invention is greatly reduced in size compared to the existing installation door, so the closing method can be changed to blocking + sealing using the sealing top plate 3. In addition to being more convenient to open and close and occupying less space, its sealing performance is also effectively improved, thereby improving the filtering effect of the filter.

[0029] In one embodiment, the support frame 1 is a support frame 1 built with square tubes as edges. The square tubes can be common hollow steel tubes, which are welded together, have lower costs, and will not block the filter element, so that it can have a better filtering effect.

[0030] Furthermore, the shape and size of the unit fixing frame 11 are exactly the same as those of the small filter element. The edge of the filter element is fixed against the edge square tube, which can effectively ensure the stability of the filter element in the unit fixing frame 11, especially the filter elements in the same row. Due to the existence of the pull-out track 13, in order to ensure smooth and convenient pulling, there is no separated and fixed structure in the X direction. The above-mentioned size limitation can make the filter elements in the same row abut against each other, making the installation more stable and not easily falling out of the unit fixing frame 11.

[0031] In a preferred embodiment, the drawer opening 21 includes an outer frame 211 and a fixing plate 212, the outer frame 211 is installed at the opening periphery of the outer shell 2, and the fixing plate 212 is installed around the edge of the outer frame 211. Further, the sealing top plate 3 includes a top plate body 31 and a sealing plate 32, the top plate body 31 has the same shape and size as the outer frame 211 of the drawer opening 21, the top plate body 31 is pushed into the drawer opening 21, and a sealing plate 32 is installed on one side of the top plate body 31 located outside the drawer opening 21, and the sealing plate 32 is tightly attached to the fixing plate 212 and sealed and fixed. The outer frame 211 and the top plate body 31 both have a certain thickness, so when the sealing top plate 3 is installed on the drawer opening 21, the top plate body 31 is pushed and blocked inside the drawer opening 21, which enhances the stability of the installation of the sealing top plate 3 and enhances the sealing performance, and the fixing plate 212 and the sealing plate 32 are independent of the outer shell 2, and are fixed to each other, so that the installation is more convenient and the sealing performance is better.

[0032] More preferably, a sealing strip 33 is installed on one side of the top plate body 31 located inside the pull-out opening 21, and a sealing strip 33 is installed on the inner side of the sealing plate 32. The top plate body 31 and the pull-out opening 21, as well as the sealing plate 32 and the fixed plate 212 are all sealed. The above-mentioned double sealing structure makes the sealing between the sealed top plate 3 and the pull-out opening 21 stronger, further ensuring the filtering effect of the filter.

[0033] More preferably, the fixing plate 212 and the sealing plate 32 are fixedly connected by bolts, and a circle of screw holes are correspondingly provided on the fixing plate 212 and the sealing plate 32, and bolts are used for sealing. The installation requires a small space, the installation is flexible, and the disassembly and assembly are convenient, which is conducive to the convenience of later maintenance or replacement of the filter element.

[0034] In one embodiment, the upper and lower four edges of the unit fixing frame 11 are provided with baffles 12 facing the inner side of the unit fixing frame 11. When two unit fixing frames 11 share an edge, the baffles 12 on the edge protrude toward the upper and lower sides, ensuring that each filter element can be effectively limited during the pulling process and after installation to avoid falling off from the support frame 1.

[0035] In one embodiment, the projection of the support frame 1 on the YZ plane falls into the interior of the pull-out opening 21 , so that each row of the pull-out rails 13 can be conveniently used to transport and install the filter element.

[0036] To sum up, the pull-out filter element support device of the present invention and the pull-out installation method using the same can install more filter elements in a limited space, and the filter elements are arranged neatly and firmly and are not easy to fall off; during installation, the installer only needs to stand at the pull-out opening on the side of the outer shell to use the pull-out track to complete the rapid installation of all filter elements. The filter product size is small, the required installation space is also extremely small, and the sealing effect is good, which is beneficial for small factories or workshops. It can be quickly installed in a small installation space, has excellent filtering effect, and is convenient for later disassembly, assembly, maintenance and replacement.

[0037] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention are all within the scope of patent protection of the present invention.
