Example Embodiment

[0013] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0014] in as figure 1 In the system shown, the cleaning device and the vibrating screening device are modified accordingly for the purpose of the present invention. One is the cleaning reactor in the cleaning device, and enough raised parts are evenly installed on the inner wall of the reactor to increase the friction between the bottle pieces in the reactor; the other is the vibration screening device, whose vibration panel is covered with small holes It is distributed in a plum blossom shape, and each aperture is 3mm. When the bottle pieces pass through, fine impurities such as dust fall into the collection box through the small holes; a certain number of V-shaped metal strips are evenly arranged on the vibration panel, and the thickness is 1mm. Vertically welded to the panel, the metal strips The interval is 4mm, and a cer...

Abstract

The invention discloses a system for cleaning and treating recycled PET bottle chips with high cleanliness. The system comprises a first pre-washing device, a first grinding device, an air separation device, a vibratory screening device, a cleaning device, a rinsing device, an output device, and a rinsing water processing subsystem. The first pre-washing device, the first grinding device, the air separation device, the vibratory screening device, the cleaning device, the rinsing device and the output device are connected in sequence; and the rinsing water processing subsystem recycles the rinsing water from the rinsing device, and sends the water back to one or two or three of the first pre-washing device, the rinsing device and the cleaning device for reutilization after the rinsing water is filtered and purified. The PEC bottle chip cleaning and treating system fully takes impurities, pollutants, etc. in the recycled PEC bottle into consideration, and utilizes each device to clean the bottle with pertinence, thus obtaining PET bottle chips with high cleanliness; and the subsystem is adopted to treat and recycle the water, thus reutilizing waste water, greatly improving the reutilization rate of waste water and greatly saving the water resource.

Description

【Technical field】 [0001] The invention relates to a complete production line, in particular to a system for cleaning recycled PET bottle flakes. 【Background technique】 [0002] In the prior art, the cleaning equipment for PET bottle flakes, due to its simple structure and backward technology, the cleanliness of the cleaned PET bottle flakes has not been able to meet the requirements of industries such as polyester filaments and bottle blowing. In terms of the treatment and recycling of wastewater generated during the process, there are also cases of excessive discharge and serious waste of water resources. Although the current PET bottle flake cleaning equipment has made great progress in terms of technology and performance, but judging from the comprehensive index data of the final bottle flakes, it still cannot meet the standard of high cleanliness bottle flakes. [0003] PET high-cleanliness bottle flakes are widely used in industries such as polyester filaments, spunbon...
