Local fine-adjustment air rectification device for purification equipment and adjustment method of local fine-adjustment air rectification device

Abstract

The invention discloses a local fine-tuning rectification device for purification equipment and an adjusting method of the local fine-adjustment air rectification device. The local fine-tuning rectification device comprises a high-efficiency air filter and a flow uniformizing device, and is characterized in that the flow uniformizing device comprises a porous membrane and a flow uniformizing frame, the flow uniformizing frame comprises an outer frame and an inner frame, a movable space is arranged between the outer frame and the inner frame, the inner frame comprises a plurality of fixed blocks and a plurality of movable blocks, the fixed blocks are fixed to a machine box of the purification equipment through fixing screws, the movable blocks are sequentially arranged along the edge of the outer frame, a screw hole is formed in the side, corresponding to the outer frame, of each movable block, a transition hole corresponding to the screw hole is formed in the outer frame, and an adjusting screw is connected with the screw hole in the moving block from the transition hole in the outer frame. Through relative movement of the moving blocks, the porous membrane attached to the moving blocks is stretched or shrunk, and the aperture of the porous membrane is changed, so that the air outlet speed at an adjusting point position is changed, flexible adjustment of different positions of points, rows and surfaces is achieved, and laminar airflow is output.

Description

technical field [0001] The invention relates to a purification equipment technology, in particular to a local fine-tuning device and an adjustment method for the purification equipment, so that the airflow velocity passing through the device is uniform and meets the requirements for the airflow velocity in a clean environment. Background technique [0002] Clean equipment such as clean benches, biological safety cabinets, laminar flow hoods, etc. have strict requirements on the uniformity of wind speed in the state of slight wind speed (wind speed between 0m / s and 1m / s). The existing micro-wind speed airflow forming device for cleaning equipment mainly includes a fan, a diffuser plate and a filter arranged between the fan and the diffuser plate. , Rectifier board. However, the actual situation is that due to various reasons, the airflow sent from the diffuser plate is not a true laminar airflow, the uniformity of the wind speed is low, and the anti-interference ability of t...

AI Technical Summary

Problems solved by technology

[0004] Although the above two solutions solve some problems of the overall wind speed in different directions, the technicians found that the previous solutions cannot be individually adjusted in the form of points or rows in dealing with the adjustment of wind speed in some local areas.

For example, the overall wind speed has reached the standard value, but only at a certain point or points, scattered and irregular occurrences exceed the specified index range, and there is often no way to make detailed adjustments. Our technicians have always Looking for a better way to deal with
