Problems solved by technology

The traditional label removal methods are winnowing and flotation. Since the weight of impurity particles is comparable to the weight of plastic bottle flakes, the effect of removing impurities by winnowing or flotation is not ideal, which leads to the label impurity separation process cycle of plastic bottle flakes. Long, the separation efficiency is not high

Embodiment Construction

[0015] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0016] Such as figure 1 As shown, the label impurity separator for plastic bottle flakes of the present invention includes a stirring box, a feed hopper, a motor, a central shaft, a spiral blade, an air intake net for removing impurities, an absorption cover, a suction fan and an air lock.

[0017] The upper side wall of one end of the mixing box is provided with a feed inlet, the upper side wall of the other end of the mixing box is provided with a bottle flake outlet, and the upper side wall of the stirring box between the feed inlet and the bottle flake outlet is provided with an air outlet. The airflow outlet is arranged at the side of the bottle flake discharge port, and the airflow outlet is closer to the bottle flake discharge port. The bottom wall of the mixing box below the air outlet is provided with an air inlet, and the air inlet is opposit...

Abstract

The invention discloses a label impurity separator for plastic bottle sheets. A feeding opening is formed in the upper side wall of one end of a stirring box. A bottle sheet discharging opening is formed in the upper side wall of the other end of the stirring box. An airflow outlet is formed in the upper side wall of the stirring box between the feeding opening and the bottle sheet discharging opening. An airflow inlet is formed in the bottom wall of the stirring box below the airflow outlet. A feeding hopper is arranged in the feeding opening of the upper side of the stirring box. Screw blades stir the plastic bottle sheets in the stirring box under the driving action of a motor and push the plastic bottle sheets from the feeding opening to the bottle sheet discharging opening. A wind inlet impurity removing net is arranged in the airflow inlet of the bottom wall of the stirring box. A bottom cover opening of an absorbing cover communicates with the airflow outlet of the upper side wall of the stirring box. A wind inlet of a suction fan communicates with a top cover opening of the absorbing cover. A first wind closing device is arranged in the feeding opening of the stirring box.A second wind closing device is arranged in the bottle sheet discharging opening of the stirring box. The label impurity separator for the plastic bottle sheets separate labels and impurities more efficiently and thoroughly.

Description

technical field [0001] The invention relates to a label impurity separator for plastic bottle flakes. Background technique [0002] After waste plastic bottles are broken into plastic bottle flakes, in addition to the label paper, it also contains impurity particles such as sand, stones, glass slag, and broken metal, so not only the label paper must be removed, but also the impurity particles need to be separated. The traditional label removal methods are winnowing and flotation. Since the weight of impurity particles is comparable to the weight of plastic bottle flakes, the effect of removing impurities by winnowing or flotation is not ideal, which leads to the label impurity separation process cycle of plastic bottle flakes. Long, the separation efficiency is not high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a label impurity separator for plastic bottle flakes with more efficient and thorough label imp...
