Problems solved by technology

The air inlet of the fan filter device is generally fixedly connected with a filter screen for protection and preliminary filtration. However, the existing filter screen will accumulate dust, which will easily cause the mesh of the filter screen to be blocked. It is necessary to disassemble the filter plate for cleaning, and it is more troublesome to disassemble and clean

Abstract

The invention discloses an air inlet filter screen plate enabling air inlet speed to be adjustable. The air inlet filter screen plate comprises a rectangular panel and arc filter pieces. A plurality of sets of slotted holes are formed in the panel. Each slotted hole set is composed of a strip-shaped inserting groove and a rectangular air inlet hole. A plurality of filtering holes are formed in the lower ends of the filter pieces. A pair of bent blocking pieces is formed on the two side edges of each air inlet hole. Through holes are formed in the blocking pieces. A plurality of inserting and connecting holes evenly arranged along arc side walls and matched with the through holes are formed in the arc side walls at the two ends of each filter piece. Pin shafts sequentially penetrate the through holes and the inserting and connecting holes to fix the filter pieces and the blocking pieces. Arc adjusting plates are hinged to the ends of the parts, inserted in the inserting grooves, of the arc filter pieces. A pair of adjusting holes facilitating stretching-in of the human hands is formed in each adjusting plate. A dust collecting plate is connected to the bottom end of the panel and fixedly arranged on a rotating shaft in a sleeving manner. Blockage caused by dust accumulating is not likely to happen, and meanwhile the air inlet amount of a draught fan filter device can be adjusted.

Description

Technical field: [0001] The invention relates to the technical field of purification equipment, in particular to an air inlet filter screen plate with adjustable wind speed of a fan filter device. Background technique: [0002] The fan filter device is a terminal purification device that combines a fan and a filter to form its own power. To be precise, it is a modular terminal air supply device with its own power and filtering effect. The air inlet of the fan filter device is generally fixedly connected with a filter screen for protection and preliminary filtration. However, the existing filter screen will accumulate dust, which will easily cause the mesh of the filter screen to be blocked. It is necessary to disassemble the filter screen plate for cleaning, and disassembly and cleaning are relatively troublesome. [0003] In view of the above-mentioned defects, this designer, actively researches and innovates, in order to create a kind of air intake filter panel of novel s...
