Description

Recovery processing device for waste plastic bottles Technical Field The invention relates to the technical field of plastic bottle recovery processing, in particular to a recovery processing device for waste plastic bottles. Background With the wide use of plastic products, the number of waste plastic bottles is increasing, and serious pressure is caused to the environment. Therefore, the recycling treatment of the waste plastic bottles with high efficiency realizes the reutilization of resources, and the recycling treatment becomes an important problem to be solved in the current society. However, the existing recovery processing device for waste plastic bottles has a plurality of problems in practical application, and seriously affects the recovery processing effect and efficiency. In the recycling process of waste plastic bottles, crushing and smashing are key links, and the effect directly determines the quality of subsequent treatment. At present, the crushing structure of the partial recovery processing device is simpler, and an effective preliminary crushing mechanism is lacked. When a large amount of abandonment plastic bottles directly get into crushing link, because plastic bottles are different in size, great plastic bottles are easy to block in crushing case, lead to equipment failure to frequently occur, not only influence the production progress, have still increased cost of maintenance. Meanwhile, most of the existing crushing equipment adopts a single crushing mode, the layout and the movement mode of the crushing blades are not reasonable enough, and the plastic bottles cannot be crushed sufficiently and finely. This makes the crushed pieces of plastic uneven in size, wherein there may be large pieces of plastic, and these unqualified pieces may affect the subsequent sieving and reprocessing process, reduce the quality of the recycled plastic, and make it difficult to meet the market demand for recycled plastic. Screening is an important step for ensuring the quality of finished products in the recovery treatment process, and aims to classify crushed fragments according to the granularity requirement and separate fragments meeting the standard and unqualified fragments. However, the existing recovery processing device has obvious defects in the screening link. Some devices have simple screening structure and low screening efficiency, and can not accurately separate fragments with different granularity, so that more unqualified fragments are mixed in qualified fragments, or part of qualified fragments are mixed in unqualified fragments, and the qualification rate of finished products is reduced. In addition, existing devices often lack an effective secondary treatment mechanism for the screened off reject fraction. These unacceptable fragments are typically discarded directly, resulting in wasted resources. In practice, these chips can still be acceptable recycled plastic stock after the regrind process. However, due to the lack of corresponding secondary treatment equipment and flow, the part of resources cannot be fully utilized, and the economic benefit and the environmental benefit of recovery treatment are further reduced. The existing recovery processing device for waste plastic bottles has a plurality of unreasonable parts in structural design and protective measures, and stability and safety of the device are affected. For example, in the feeding link, some devices are not provided with effectual limit material and anti-drop structure, lead to getting into broken regional plastic bottle quantity too much or too little, influence crushing effect, and the plastic bottle drops at the feeding in-process easily simultaneously, causes the confusion of material waste and production environment. In the crushing link, the transmission parts of part devices lack necessary protective measures, transmission parts such as gears are exposed to the outside and are easily influenced by dust, sundries and the like, so that the abrasion of the gears is increased, the transmission precision is reduced, and even equipment faults are caused. Moreover, operators can easily touch the transmission parts in the running process of the equipment, and great potential safety hazards exist. In screening link, some devices do not be provided with effectual filtration and ash discharge structure, impurity that mingles with in the piece after smashing can not in time separate and discharge, and these impurity can accumulate inside the device gradually, influence screening effect and the normal operating of device, have also increased the maintenance degree of difficulty and the cost of equipment simultaneously. Disclosure of Invention In order to solve the above problems, the present invention provides a recycling device for waste plastic bottles, so as to solve the above problems in the prior art more precisely. The invention is realized by the following technical scheme: The invention provides a recycling device
