Whole seal type highly effective air purification air supply outlet

Abstract

The invention relates to a completely sealed type high-efficiency air purification air outlet. It includes a static pressure box, a high-efficiency filter, and a base. One side of the static pressure box is provided with an air inlet, and the static pressure box and the high-efficiency filter are arranged up and down. The filter is pressed on the base by the pressing buckle device; the sealing between the static pressure box and the high-efficiency filter and the base is double-sided pressing, the structure is reasonable, the sealing is reliable, and the small leakage airflow will not leak into the clean room, completely avoiding The pollution leakage is avoided; the compression buckle device is adopted, which is convenient for installation and disassembly, and the operator can complete the whole process of replacing the high-efficiency filter without entering the purification area, so as to avoid the pollution of the purification area by personnel; the static pressure box is equipped with a pull The handle is easy to carry and install; it can be directly matched with a variety of high-efficiency filters of different thicknesses, and has a wide range of applications. It is mainly suitable for air supply outlets in clean rooms, as well as purification equipment and air purification projects that require high sealing.

Description

technical field [0001] The invention belongs to the field of air purification equipment and relates to a completely sealed type high-efficiency air purification air outlet. Background technique [0002] At present, the structure of the air purification outlet widely used in China refers to figure 1 As shown, the upper part and the lower part of the static pressure box 1 are an integral structure, the high-efficiency filter 3 is arranged in the lower part of the static pressure box 1, and the lower part of the static pressure box 1 is connected with the flat base 4 by bolts , the sealing between the upper part and the high efficiency filter 3 is realized by mechanically pressing and applying sealant in the positive pressure range; its disadvantage is (1) the static pressure box is an integral structure, if the seal is not tight, there will be small leakage, The airflow will leak into the clean room in the direction of the arrow in the figure, and it cannot be guaranteed that...

[0002] At present, the structure of the air purification outlet widely used in China refers to figure 1 As shown, the upper part and the lower part of the static pressure box 1 are an integral structure, the high-efficiency filter 3 is arranged in the lower part of the static pressure box 1, and the lower part of the static pressure box 1 is connected with the flat base 4 by bolts , the sealing between the upper part and the high efficiency filter 3 is realized by mechanically pressing and applying sealant in the positive pressure range; its disadvantage is (1) the static pressure box is an integral structure, if the seal is not tight, there will be small leakage, The airflow will leak into the clean room in the direction of the arrow in the figure, and it cannot be guaranteed that all the airflow flowing into the clean room is clean air filtered through high-efficiency filters; (2) The installation process is complicated, and leakage will occur if the installation is improper or the operation is not rigorous (3) the process of applying the sealant is complicated, the installation is inconvenient, and it is very difficult to cut and clean the sealant when changing the filter; (4) to operate in the purification area when changing the filter, it is easy to cause pollution in the purification area; ( 5) It is inconvenient to disassemble the diffuser when replacing the filter; (6) The existing high-efficiency air supply port is only suitable for a single thickness of high-efficiency filters, not for multiple thicknesses of high-efficiency filters

[0003] In the nine years from the beginning of 1995 to April 2004, I have used about 385 air purification outlets in many air purification projects. Among them, in 13 projects, 36 air outlets leaked, which brought great harm to the project. huge loss
