Integrated complete equipment and method for crushing, washing and separating discarded plastics

Abstract

The invention discloses integrated complete equipment and method for crushing, washing and separating discarded plastics. The complete equipment comprises a crushing device, a washing and separating device and a dewatering device, sequentially connected, wherein the washing and separating device comprises a first dewatering machine with a washing basket and separating grooves used for separating different densities of materials; the dewatering device comprises a second dewatering machine with a washing basket; a first-section washing water circulating system is arranged between the first dewatering machine and the crushing device; and a second-section washing water circulating system is arranged between the second dewatering machine and the separating grooves. The integrated complete equipment can carry out crushing, washing and separating integrated treatment on discarded plastics so as to reduce space occupied by plastic recycling and clear residues on plastics. The integrated complete equipment has the advantages of being high in automation degree, small in water usage, conservative in labor, compact in structure, small in land occupation and the like.

Description

technical field

[0001] The invention relates to a plastic recycling equipment and method, in particular to a complete set of integrated equipment and method for crushing, cleaning and sorting discarded plastics. Background technique

[0002] The good processing performance and pleasing appearance of plastic products are widely favored by human beings, and their applications are becoming more and more extensive. They are indispensable in human production and life; It hardly degrades under the environment, and the discarded objects after use have caused serious harm to the environment and ecology. According to statistics, the average life cycle of plastic products is 4-8 months, and the amount of discarded plastic products is huge. The recycling of discarded plastics has become an important part of the circular economy. Discarded plastics often have the characteristics of many voids and large volumes, such as various bottles, barrels, basins, etc., and the recycling site take...

Examples

Embodiment 1

[0041] see figure 1 and figure 2 , the waste plastic crushing, cleaning and sorting integrated complete set of equipment in this embodiment includes a crushing device 1, a cleaning and sorting device, and a dehydration device connected in sequence; wherein, the cleaning and separation device includes a first dehydrator 2 with a washing cage and a separation device. Tank 3; the dehydration device includes a second dehydrator 4 with a washing cage, and the washing cage is used to clean materials and remove large particles of sediment and other impurities.

[0042] see figure 1 A first section of the cleaning water circulation system 6 is provided between the first dehydrator 2 and the crushing device 1, and the first section of the cleaning water circulation system 6 includes a skimmer 6-1 connected to the water outlet of the first dehydrator 2, Pipelines, pumps 6-2, valves, etc. connecting the skimmer 6-1 and the crushing device 1; a second stage of cleaning water circulatio...

Embodiment 2

[0061] see Figure 7 with Figure 8 , the difference between this embodiment and embodiment 1 is that in this embodiment:

[0062] The four combined modules are arranged in a right-angle shape, specifically, a 90-degree bend is performed between the second combined module and the third combined module.

[0063] The separation tank 3 has a three-section structure, which is respectively a first separation section 3-1, a second separation section 3-2 and a third separation section 3-8, which can separate at least four kinds of materials with different densities.

Embodiment 3

[0065] see Figure 9 , the difference between this embodiment and embodiment 2 is that in this embodiment:

[0066] The arrangement of the four combined modules has two right-angled bending points, specifically a 90° bend between the second combined module and the third combined module; a 90° bend between the third combined module and the fourth combined module folded, and bent towards the material conveying direction in the first combination module.
