[0031] Example
[0032] like Figures 1-2 As shown,
[0033] The existing static pressure box consists of two parts: a static pressure box 1 and a suspended laminar flow support 3. Lifting rods 4 are installed at the four opposite corners of the suspended laminar flow support 3. These lifting rods 4 pass through the static pressure box lifting holes 5 from bottom to top, and the flow equalization membrane is installed on the suspended laminar flow support 3. This structure has high manufacturing and transportation costs for the support, a long manufacturing cycle, and the support is prone to deformation, increasing after-sales costs.
[0034] like Figures 3-6 As shown,
[0035] A suspended laminar flow static pressure box includes a static pressure box 1, with a flow equalization membrane installation window for installing a flow equalization membrane on the lower inner side of the static pressure box 1, and a filter rack 2 installed inside the static pressure box 1 near the flow equalization membrane installation window.
[0036] 1. Lifting structure inside static pressure box 1:
[0037] Static pressure box 1 has four opposite corners at the top of the static pressure box 1. A hoisting connecting block 6 is installed on the static pressure box 1 inside the bottom of the static pressure box hoisting connecting block 5. A connecting block hoisting connecting block 8 is opened in the middle of the hoisting connecting block 6, which is coaxial with the static pressure box hoisting connecting block 5. The top of the hoisting rod 4 passes through the connecting block hoisting connecting block 8 and the static pressure box hoisting connecting block 5 from bottom to top and extends to the top of the static pressure box 1. The bottom of the hoisting rod 4 is locked to the bottom of the connecting block hoisting connecting block 8 by the hoisting rod locking block 9.
[0038] The hoisting connection block 6 is welded inside the static pressure box 1, and the hoisting connection block 6 is set in an L-shaped structure.
[0039] 2. Installation structure of the flow equalization membrane and flow equalization membrane baffles:
[0040] A flow equalization membrane baffle 7 is installed on the outer side of the flow equalization membrane installation window. Specifically, flow equalization membrane baffles 7 are installed around the outer perimeter of the flow equalization membrane installation window.
[0041] The flow equalization membrane baffle 7 includes a front baffle 10 located at the bottom, and a rear baffle 11 bent inside the top of the front baffle 10. The rear baffle 11 is used to place and support the flow equalization membrane, and the front baffle 10 is located at the front end of the flow equalization membrane to limit and protect it from external impact.
[0042] 3. Adjusting the installation position of filter holder 2:
[0043] The distance between the filter frame 2 and the bottom of the static pressure box 1 is 100mm to 140mm. Specifically, the distance between the filter frame 2 and the bottom of the static pressure box 1 is 140mm.
[0044] The existing filter rack has a low installation height. This invention raises the installation height of the filter rack, which makes it easier to install the flow equalization membrane on the flow equalization membrane installation window.
