Detailed ways

Below in conjunction with accompanying drawing, the optimized implementation mode of the present invention is further described:

As shown in Figure 1, each equipment is distributed from right to left according to the process, including: conveyor belt 1, label remover 2, sorting table 8, metal detector 12, crusher 3, washing machine 4, steamer Pot 5, dehydrator 6 and silo 7, wherein, the conveyor belt 1 is used to transport the mineral water bottles placed on it to the delabeling machine 2, and the delabeling machine 2 is used to separate the labels on the mineral water bottles, and can remove the labels at the same time. About 50% of the bottle caps; the sorting table 8 is used to sort the off-label bottles, and pick out 5% of the non-off-label bottles, which will be transported to the off-label machine 2 again Secondary off-label; Crusher 3 is used to crush the bottle body after completely off-label into bottle flakes, in the present embodiment, there is a water spray pipe on the top of the hopper of the crusher 3, by spraying water in the crusher 3, can Reduce the heat generated during the crushing process to increase the service life of the cutter head of the crusher, and at the same time play a pre-cleaning effect. A screw feeder 13 is arranged below the crusher 3, and the feeder 13 inputs the bottle flakes to the cleaning machine 4. In the present embodiment, the cleaning machine 4 includes a horizontal cleaning machine 41 and a twin-screw cleaning machine 42 arranged before and after the horizontal cleaning. The function of machine 41 is to break up the broken bottle flakes under the high-speed operation of the screw rod of the horizontal cleaning machine, and the top can be flushed with water, so that the sundries can be removed from the screen holes of the horizontal cleaning machine, and the broken bottle flakes enter the double-sided cleaning machine. After the screw washer 42 is in full contact with water, the friction of the screw can achieve the purpose of cleaning. At the same time, there is an overflow port on the upper part of the screw washer, and the continuous injection of water can make the bottle caps floating on the water overflow (PET bottle flakes are faster than water The bottle cap is made of PE material, which is lighter than water and floats on the surface of the water to be discharged to achieve the purpose of separation). The feeder 13 between 5 enters the steamer 5, and cleaning agent can be added in the steamer 5, so that the bottle flakes can be cleaned more cleanly. quality. In the present embodiment, after the steamer 5, two cleaning machines are also provided, also being a horizontal cleaning machine 10 and a twin-screw cleaning machine 11, which can further remove the impurities on the bottle flakes. Cleaning agents and deep cleaning purposes. Finally, the thoroughly cleaned bottle flakes enter the dehydrator 6 for dehydration. The dehydrated bottle flakes enter the feed bin 7 through the drying equipment arranged behind the dehydrator 6 to be stored in bags. In the present embodiment, the drying equipment 9 includes a drying pipe 91, an electric heater is arranged in the drying pipe 91, and the dehydrated bottle flakes are blown into the drying pipe 91 through a blower fan 92, and passed through the hot air in the drying pipeline to further Reduce the moisture content of bottle flakes.

The entire operation process of the PET mineral water bottle recovery, crushing and cleaning line in this embodiment is as follows: PET mineral water bottle → conveyor belt → label removal machine → sorting conveyor → conveyor belt → crusher → screw feeder → horizontal cleaning machine → screw cleaning machine → Spiral feeder→steamer hot water cleaning machine→screw feeder→horizontal cleaning machine→screw cleaning machine→screw feeder→dehydrator→pipeline drying→air conveying equipment→cyclone silo→bags.

The above-mentioned entire production line adopts an electrical control cabinet 14 centralized control, only 3~4 people are needed on the production site (the sorting conveyor needs 3~4 people for sorting), and the output can reach 500~3000kg/h, which is a good realization of automation production, reducing the number of workers in the factory, and multi-channel cleaning to make the material cleaner.

To sum up, the PET mineral water bottle recycling crushing cleaning line in this embodiment has the following advantages:

1. Continuous automatic production can get rid of the current situation of dirty and chaotic production sites in the plastic recycling industry.

It embodies the corporate philosophy of "people-oriented, improving the environment, and recreating value";

2. A de-labeling machine is added to separate labels to make PET bottle flakes more pure;

3. The hot air drying of the dehydrator and the pipeline makes the moisture content of the film after cleaning lower, which is good for the subsequent spinning

Silk;

4. Multi-channel cleaning makes the quality of PET flakes higher.

The above-mentioned combination has described the preferred embodiment of the present invention, but the above-mentioned embodiment can not be interpreted as limiting the scope of protection of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection of the present invention. within range.
