Whole seal type highly effective air purification air supply outlet

Abstract

The present invention relates to a fully enclosed type high-efficient air cleaning feeding opening, comprising a static pressure box body, a high-efficient filter and a base. One side of the static pressure box body is provided with an air feeding opening. The static pressure box body and the high-efficient filter are up and down arranged. The base is provided with a hanging ring. The static pressure box body and the high-efficient filter are tightly pressed on the base by a pressing clamp device. A dual-sided tight pressing is used for the sealing between the static pressure box body, the high-efficient filter and the base. The present invention has reasonable structure, reliable sealing, and the airflow of the micro leakage can not leak into a cleaning room and the pollution and leakage is completely avoided. By adopting the pressing clamp device, the assembling and the detachment are facilitated, the full processes of the replacement of the high-efficient filter can be completed without the operator accessing into the cleaning area, and the pollution caused by the operator is avoided. The handling and assembling of the static pressure box body is facilitated by a sliding handle. The present invention can be directly matched with the high-efficient filter of different thicknesses, wide in the ranges of application, and is mainly suitable for the feeding opening of the cleaning room, and the cleaning equipment and air cleaning project with higher requirement of tightness.

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 air purification outlet structure widely used in China is shown in Fig. The lower part of the pressure box body 1 is bolted to the flat base 4, and the sealing between the upper part and the high-efficiency filter 3 is realized by mechanical compression and smearing of sealant within the positive pressure range; the disadvantages are (1) the static pressure box The body is an integral structure. If there is a small leak if the seal is not tight, the airflow will leak into the clean room in the direction of the arrow in the figure. It cannot be guaranteed that all the airflow flowing into the clean room is clean air filtered by the high-efficiency filter; (2) Installation The process is complicated, and leakage will occur once the installation is improper or t...

If there is a small leak if the seal is not tight, the airflow will leak into the clean room in the direction of the arrow in the figure. It cannot be guaranteed that all the airflow flowing into the clean room is clean air filtered by the high-efficiency filter; (2) Installation The process is complicated, and leakage will occur once 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 replacing the filter; (4) When replacing the filter, it is necessary to It is easy to cause pollution in the purification area when operating in the purification area; (5) When replacing the filter, it is inconvenient to disassemble the diffuser plate from a height; (6) The existing high-efficiency air supply port is only suitable for a single-thickness high-efficiency filter and cannot be used High-efficiency filters in various thicknesses

[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
