Description

Technical Field

[0001] The utility model relates to the technical field of recycled polyester bottle flake production, in particular to production equipment for recycled polyester bottle flakes. Background Art

[0002] At present, the presence of metal impurities (iron filings, aluminum filings, copper filings, etc.) and non-metallic impurities (sand, cement blocks, gravel, etc.) is unavoidable in the process of PET bottle flakes recycling. Except for iron filings, these impurities can be removed by strong magnets during paper separation, cleaning or filling processes. Aluminum filings, copper filings, sand, gravel, cement blocks, etc. are not magnetic or have a higher specific gravity than PET bottle flakes. Usually, a single solution (such as saturated salt water, calcium chloride solution, etc.) cannot be used to separate PET bottle flakes from the above impurities. The presence of these impurities will seriously affect the service life of the equipment.

[0003] Although electrostatic separation and flotation separation used in most existing technologies can separate some impurities, they are expensive, require large equipment investment, have low separation efficiency and are complex to operate.

[0004] For example, a production device for separating recycled polyester bottle flakes by a specific gravity method disclosed in Chinese patent CN109822780A drives a cam and a second stirring rod to rotate through a driving mechanism, and can vibrate and stir the materials in the stirring tank and the separation box respectively, so as to achieve a better separation effect of the recycled polyester bottle flakes. The recycled polyester bottle flakes are added to a sodium chloride white oil water mixture for preliminary separation, and then the separated recycled polyester bottle flakes are added to water for re-separation, which is not only low in cost but also simple to operate.

[0005] However, impurities such as mud, sand and gravel separated by the device during use will adhere to the inside of the mixing tank, making it inconvenient to clean the mixing tank.
