Description

Technical Field

[0001] The utility model relates to a bottom-mounted and bottom-detachable FFU filter unit device, belonging to the technical field of fan filter units. Background Art

[0002] FFU filter unit device is a fan filter unit, which is generally installed on the ceiling of the clean workshop. In actual construction, the height of the clean workshop is often too low, resulting in insufficient space above the technical mezzanine to accommodate construction personnel, making installation difficult and maintenance and replacement even more difficult.

[0003] In the prior art, one installation method of the FFU filter unit device requires first lifting the FFU box through the U-shaped keel, then twisting the support mechanism installed on both sides of the FFU box to unfold it, and then lifting the high-efficiency filter by hand until it contacts the FFU, and continue to lift it up together with the FFU, and then install four auxiliary structures around the other U-shaped aluminum profiles, and then slowly move your hands down to support the high-efficiency filter and FFU on it, and the installation is completed. The removal process steps are reversed.

[0004] The above installation method has high material costs because it needs to pretend 2 supporting mechanisms and four auxiliary structures; it is too complicated in terms of installation and construction, and 2-3 people are needed to assist in the installation; and the load-bearing strength of the product after installation is poor, which makes it easy for people to step on and fall; and maintenance and replacement are also equally complicated. Utility Model Content

[0005] The utility model provides a bottom-mounted and bottom-detachable FFU filter unit device, which aims to overcome the above-mentioned shortcomings of the prior art, reduce material costs, and simplify installation, construction, maintenance and replacement.

[0006] The technical solution of the utility model is a bottom-mounted and bottom-detachable FFU filter unit device, whose structure includes a high-efficiency filter and an FFU outer frame. The high-efficiency filter is located in the opening of the FFU outer frame. A plurality of fixing mechanisms are evenly spaced at the edge of the FFU outer frame opening, and handles are respectively provided at the centers of the edges around the FFU outer frame opening.

[0007] Preferably, the fixing mechanism is a fixing plate, which is rotatably connected to the FFU outer frame via a rotating shaft. When the fixing plate rotates to the outside of the FFU outer frame opening, it does not contact the high-efficiency filter. When the fixing plate rotates to the inside of the FFU outer frame opening, it supports the edge of the high-efficiency filter.

[0008] Preferably, a slide groove opening outward is provided on the inner side around the opening of the FFU outer frame, and a sliding bar arranged along the length direction of the opening of the FFU outer frame is provided in the slide groove. The handle passes through a slot hole opened on the FFU outer frame and is connected to the sliding bar. The slot hole is arranged along the width direction of the slide groove. When the FFU outer frame is installed in the hole formed by the FFU keel, the handle slides to the outermost side along the slot hole, and the sliding bar slides along the slide groove to the outer side of the slide groove opening and is supported on the FFU keel.

[0009] The utility model has the advantages of simple and reasonable structural design, can be installed and disassembled by one person, is easy to maintain and replace, and can effectively reduce material costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention is further described in detail below in conjunction with embodiments and specific implementation methods.

[0016] like Figure 1-3 As shown, a bottom-mounted and bottom-detachable FFU filter unit device has a structure comprising a high-efficiency filter 1 and a FFU outer frame 2. The high-efficiency filter 1 is located in the opening of the FFU outer frame 2. A plurality of fixing mechanisms are evenly spaced at the edge of the opening of the FFU outer frame 2, preferably fixed plates 3. The fixed plates 3 are rotatably connected to the FFU outer frame 2 through a rotating shaft. When the fixed plates 3 are rotated to the outside of the opening of the FFU outer frame 2, they do not contact the high-efficiency filter 1. When the fixed plates 3 are rotated to the inside of the opening of the FFU outer frame 2, they support the edge of the high-efficiency filter 1. Handles 4 are respectively provided at the centers of the edges around the opening of the FFU outer frame 2.

[0017] like Figure 4As shown, a slide groove 7 opening outward is provided on the inner side around the opening of the FFU outer frame 2, and a sliding bar 6 is provided in the slide groove 7 along the length direction of the opening of the FFU outer frame 2. The handle 4 passes through a slot 5 opened on the FFU outer frame 2 and is connected to the sliding bar. The slot 5 is arranged along the width direction of the slide groove 7. When the FFU outer frame 2 is installed in the hole formed by the FFU keel 8, the handle 4 slides to the outermost side along the slot 5, and the sliding bar 6 slides along the slide groove 7 to the outer side of the opening of the slide groove 7 and is supported on the FFU keel 8.

[0018] According to the above structure, only one operator is needed for installation. First, place the FFU outer frame 2 with the opening facing upward on a clean work platform, then place the high-efficiency filter 1 in the opening with both hands, and pay attention to the installation direction of the high-efficiency filter 1. After the high-efficiency filter 1 is placed in, twist the surrounding fixing plates 3 to fix the high-efficiency filter 1 in the FFU outer frame 2. Then grab the handles 4 on both sides with both hands, and gently lift them up from under the hole of the FFU keel 8. After lifting it onto the FFU keel 8, pull the handles 4 outward, then release both hands, and then pull the other two handles 4 in the corresponding directions outward in the same way to complete the installation.

[0019] When disassembling, follow the same steps as above, hold the left and right handles 4 and pull them inwards, then change the corresponding direction and pull the left and right handles 4 inwards, and you can easily take out the FFU frame 2 and the high-efficiency filter 1 as a whole. If you do not need to take out the FFU frame 2, and only need to replace the high-efficiency filter 1, just rotate the fixing plate 3 to take out the high-efficiency filter 1, and after replacing the new high-efficiency filter 1, rotate the fixing plate 3 back to its original position. The entire installation process only requires one operator, which is convenient and efficient.

[0020] All the components mentioned above are prior art, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
