Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with specific embodiments.

[0038] like Figure 1 to Figure 6 As shown, a FFU installation structure of the present invention includes a mounting frame 2 arranged around the chassis 1, the mounting frame 2 is provided with a number of mounting holes 21, and the mounting frame 2 is fixed by screws 6 and nuts 7 passing through the mounting holes 21. On the framework 3, several rigid spacers 4 and flexible sealing strips 5 are sandwiched between the mounting frame 2 and the framework 3. The spacers 4 are located on the periphery of the mounting hole 21, and the sealing strips 5 are attached to the installation One side of the frame 2 is also provided with an escape groove 51 for avoiding the spacer 4 . The chassis 1 is placed on the frame 3 through the surrounding mounting frames 2, and the mounting frame 2 and the frame 3 are fixed by screws 6 and nuts 7, so the actual assembly can be install...

Abstract

The invention belongs to the technical field of cleaning equipment, and relates to an FFU installation structure. The FFU installation structure comprises an installation frame arranged on the periphery of a machine case, a plurality of installation holes are formed in the installation frame, the installation frame penetrates screws and nuts of the installation holes to be fixed to a framework, a plurality of rigid limiting gaskets and flexible sealing strips are clamped between the installation support and the framework, the limiting gaskets are located on the peripheries of the installation holes, and the sealing strips are attached to one face of the installation frame and are provided with avoiding grooves avoiding the limiting gaskets. By means of the FFU installation structure, a screw fixation manner is adopted, the FFU machine case is fixedly connected to the framework, sealing is achieved through the limiting gaskets and the sealing strips which are of special structures, installation is facilitated, and the better sealing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of clean equipment, in particular to an FFU installation structure with convenient installation and good sealing. Background technique [0002] The full name of FFU is Fan Filter Units, which means "Fan Filter Unit" in Chinese. At present, the common FFUs on the market are directly placed on the frame, and the filter is pressed by the gravity of the FFU itself, without any fastening measures. The disadvantages of this installation structure are: [0003] ① Personnel need to work at heights, step on the skeleton to place the FFU, and there needs to be enough space on the top so that personnel can stretch their bodies to work. [0004] ②The FFU and the frame cannot be completely sealed, and the external dust will enter the clean room from the unsealed place, which affects the filtration efficiency of the FFU and the process quality of the clean room. [0005] Therefore, it is necessary to provide a new inst...
