Description

Technical Field

[0001] The utility model relates to the technical field of fully biodegradable plastic particles, and particularly relates to a filtering device for fully biodegradable plastic particles. Background Technique

[0002] As is well known, with the increasing awareness of environmental protection, fully biodegradable plastic particles have been widely used due to their characteristics of complete degradability and environmental friendliness. However, during the production, processing, and recycling processes, various impurities will inevitably be mixed into the fully biodegradable plastic particles, which not only affects the purity and performance of the products but also may cause damage to subsequent processing equipment.

[0003] At present, for the filtering devices of fully biodegradable plastic particles, although there are various designs on the market, there are still many inconveniences in the replacement and cleaning of the filter screens. Traditional filtering devices often use fixed filter screen plates. Once the filter screen plates are blocked or need to be replaced, the entire filter box needs to be shut down and disassembled, which not only increases the downtime, reduces the production efficiency, but also has complex operations and increases the maintenance cost.

[0025] During use, pour the fully biodegradable plastic particles into the feed pipe 2. Under the action of gravity, the particles pass through the filter screen plate 13. Larger particles and sundries are blocked on the filter screen plate 13, while normal particles pass through the filter screen plate 13 and enter the lower collection area. At this time, start the vibrator 14. The vibration generated by the vibrator 14 will cause the filter screen plate 13 to have a small displacement and vibration, thereby loosening and shaking off the particles blocked on the mesh holes and improving the filtering effect. After filtering, open the valve to pour out the particles from the discharge pipe 10. Pull out the limit rod 8 from the fixed ring 18 and the sliding hole, and move the handheld block 9.

At this time, the filter screen plate 13 is already installed. Close the baffle 6, align the locking column 7 with the fixing hole, release the handheld block 9, and the spring 15 extends under its own elastic force, driving the slider 17 to move. The locking column 7 moves accordingly and passes through the fixing hole. At this time, the sliding hole coincides with the fixed ring 18, and pass the limit rod 8 through the sliding hole and the fixed ring 18 for locking.
