A roll-up filter

Abstract

The invention provides a rolling-up curtain type filter. When a filter material is replaced, the whole filter can still realize air purification and ensure that the air purification is carried out continuously, therefore, the production can be carried out continuously. The rolling-up curtain type filter comprises a main body frame, wherein the main body frame comprises an upper box body, a lower box body and a middle filtering area, guiding devices are arranged inside the upper box body and the lower box body respectively, the guiding devices are externally connected with a power device, a filter material structure is arranged on the windward side of the middle filtering area between the upper box body and the lower box body, the filter material structure is driven by the guiding device, thus, the filter material structure capable of moving towards the specific box body can be formed; the rolling-up curtain type filter is characterized in that the rolling-up curtain type filter also comprises a standby filter material which is folded at one end, positioned at the windward side, of the upper box body / or the lower box body, and the standby filter material is located at the front end of the windward side of the filter material structure when being unfolded and covers the windward side of the filter material structure when being unfolded.

Description

technical field [0001] The invention relates to the technical field of filter structures, in particular to a roll-up filter. Background technique [0002] Existing roll filter mainly comprises upper and lower filter material rolls, a roll of filter material mounted on the upper and lower filter material rolls and a motor that drives the rotation of the lower filter material rolls. When in use, a plurality of such filters are arranged side by side to form an air curtain, and when the air passes through the air curtain, the filter material will filter the air to purify the air. A differential pressure sensor is installed at the front and rear of the filter material curtain. When the dust on the filter material is saturated, the differential pressure sensor gives a signal to start the motor, and the controller starts the motor to drive the lower filter material roller to rotate, thereby removing the dirty filter material. The section is rolled up and replaced with a clean filt...

Problems solved by technology

When replacing, the roller shutter filter stops working. At this time, once the external equipment continues to be used, the unfiltered air will directly enter the lower circulation, making the entire internal environment polluted; because the existing roller shutter filter is due to the need Replacing the filter material makes it difficult to continuously purify the air, especially in harsh weather such as sandstorms, the dust on the filter material will soon become saturated. However, it is very difficult to quickly replace the filter material in harsh weather, and it is often difficult to implement. Therefore, it is possible to cause production shutdown and cause great losses to production
