Description

Technical Field

[0001] The utility model belongs to the technical field of flow equalizing membrane installation, and in particular relates to a flow equalizing membrane installation fixing structure. Background Art

[0002] The function of the flow equalizing membrane is to make the airflow coming down from the high-efficiency filter at the outlet be evenly laminated downward without forming a turbulent state, so as to better control the cleanliness to achieve the effects of ten thousand, one thousand, and one hundred. How to fix the flow equalizing membrane on the high-efficiency air outlet is crucial.

[0003] After using the high-efficiency filter for a period of time, it needs to be inspected or replaced regularly. The flow equalizing membrane is currently installed in the market with bolts or retaining rings. The bolt fixing method is troublesome to disassemble, and the exposed bolts will have the risk of harbouring dirt in the clean room. The retaining ring fixing method requires the use of special tools and has high requirements for the installer. The above installation methods all require two people to operate at the same time (one person fixes the position of the flow equalizing membrane, and the other person installs the bolts or retaining rings). If the operation is improper, it is easy to cause damage to the high-efficiency filter or the flow equalizing membrane. Utility Model Content

[0016] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] The utility model provides Figure 1-4 A flow balancing membrane installation and fixing structure shown in the figure includes an outer frame 1, a bead device 2, and a flow balancing membrane 6. The bead device 2 includes a shell 3, a spring 4 and a bead 5. The spring 4 and the bead 5 are arranged in the shell 3, and the bead 5 is arranged on the outside of the spring 4. An opening is arranged on one side of the bead 5 corresponding to the shell 3, and the bead 5 protrudes from the opening. Raised plates are integrally arranged on the edges of the shell 3 on both sides of the bead 5. The bead device 2 is fixed to the outer frame 1 by welding or bolts, and the flow balancing membrane 6 is installed in the outer frame 1. The bead 5 is stuck in the flow balancing membrane groove 7 at the edge of the flow balancing membrane 6, and a high-efficiency filter 8 is arranged on the upper side of the flow balancing membrane 6.

[0018] The shape of the bumping ball 5 is set to be spherical, cylindrical, or elliptical. Specifically, the device uses a spherical bumping ball 5.

[0019] The installation position of the bead device 2 is single-sided installation, double-sided installation, three-sided installation or four-sided installation, and the number of the bead devices 2 can be adjusted according to the size of the flow-balancing membrane; specifically, the device adopts double-sided installation, with two bead devices 2 installed on each side; the bead 5 can be made of metal or plastic.
