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

The invention discloses a local fine-tuning device for purification equipment and an adjustment method thereof, which includes a high-efficiency air filter and a flow uniformity device, and is characterized in that the flow uniformity device includes a porous membrane and a flow uniformity frame, and the The uniform flow frame includes an outer frame and an inner frame, and there is a movable space between the two frames. The inner frame includes several fixed blocks and several movable blocks, and the fixed blocks are fixed to the chassis of the purification equipment by fixing screws. The moving blocks are arranged in sequence along the edge of the outer frame, and each moving block is provided with a screw hole corresponding to one side of the outer frame, and a transition hole corresponding to the screw hole is provided on the outer frame, and the adjustment screw can be adjusted from the The transition hole on the outer frame is connected with the screw hole on the moving block. The present invention stretches or shrinks the porous film attached to the moving block through the relative movement of the moving block to realize the change of the aperture of the porous film, thereby changing the wind speed at the adjustment point to achieve different positions of points, rows and surfaces Flexible adjustment, output laminar airflow.
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...
