The invention relates to a plastic filtering device with a cylindrical filter, mainly through the cylindrical filter and the scraper block of the feeding screw, which can quickly filter plastic particles and scrape off impurities in a large area.

By the way, most of the conventional plastic filter devices are generally equipped with a cylindrical filter outside the feeding screw; after a period of use, it is necessary to stop the machine, clean the filter and then restart the machine, which often consumes a lot of energy. A lot of time affects the progress of raw material delivery. And because the cylindrical filter screen is not easy to completely filter the waste materials during filtration, the filtered raw materials are not yet refined, so it not only consumes the time of raw material output, but also easily blocks the waste materials, which is not in line with economic benefits.

In order to solve the inconvenient use and poor effect of the filter screen of the traditional plastic filter device, the inventor invented a plastic filter device with a cylindrical filter screen, which can scrape off impurities at the same time during the filtration process, reduce the number of times to replace the filter screen, and improve the filtering effect. good.

The cylindrical filter screen of the conventional plastic filter device has limited efficiency and is easy to catch waste, which is time-consuming, costly and time-consuming, and is not economical.

The invention is a plastic filtering device with a cylindrical filter net, which mainly has a feeding trough and a waste material trough. The feed tank has a motor, feeding screw and cylindrical filter; the waste tank has a motor and waste screw. There is a feeding screw threaded inside the feeding trough, and the shaft is equipped with several scraper blocks, which are connected and rotated by a motor located at the outer end. There is a feeding port under the feeding chute; On one side, a discharge port is arranged on the top, and the feeding screw extends to the inside of the cylindrical filter. There is a motor at one end of the waste tank, and there is a waste screw inside, which is connected and rotated by the motor, and several waste discharge holes are arranged on the top.

When the present invention is assembled, the feeding trough is sequentially connected to the waste trough, and the feeding screw is extended into the cylindrical filter screen to penetrate the feeding trough. When in use, the plastic raw material is fed in from the feeding port below the feeding trough, and the motor drives the feeding screw to rotate, so that the plastic raw material is introduced into the cylindrical filter, and after the impurities are filtered through the cylindrical filter, the raw material is discharged from the upper part of the filter cylinder. The material port is exported; the impurities enter the waste material tank at the rear, and then the impurities are exported by the waste material screw inside, and discharged from the waste material discharge hole above. This case uses the cylindrical filter, which can quickly filter plastic particles in a large area and cooperates with the feeding screw. The number of scraper blocks on the shaft scrapes off the waste and impurities, and can be used for a long time, reducing the number of times to replace the filter and achieving high efficiency.
