Novel device capable of washing and removing impurities of PET bottle pieces

Abstract

The invention relates to a device capable of washing and removing impurities of PET bottle pieces and particularly relates to a novel device capable of washing and removing impurities of PET bottle pieces. The device comprises a tank body, a horizontal screw auger conveyor and an oblique screw auger conveying mechanism, wherein a feeding hole, a tank bottom flushing mechanism, a water-sucking and dust-removing mechanism and an impurity salvaging mechanism are arranged in the tank body in sequence; the horizontal screw auger conveyor is arranged at the bottom of the tank body; the oblique screw auger conveying mechanism is arranged at the tail end of the horizontal screw auger conveyor; a discharging hole is formed in the tail end of the tank body; a bottom feeding hole of the oblique screw auger conveying mechanism is connected to the discharging hole of the tank body; a water outlet is formed in the tail end of the left side of the tank body; a filtering device is arranged under the water outlet. The device is capable of washing and removing impurities of PET bottle pieces at the same time, and has the characteristics of high washing and impurity removing efficiency and high cleanliness of materials.

Description

technical field [0001] The invention relates to a recycling, cleaning and impurity removal device for PET bottle flakes. Background technique [0002] In the chemical fiber industry, a large part of the raw material is PET bottle flakes. The whole bottle is crushed by a shredder and turned into bottle flakes. However, because there are still a lot of residual substances on the bottle, and it has been exposed to the outside world for a long time, there are relatively large amounts of PET bottle flakes. There are many impurities, so the bottle flakes must be cleaned first, and then go to the subsequent spinning process. Generally, the cleaning of bottle flakes needs to go through processes such as flotation, high-temperature boiling, and clear water rinsing. Among these processes, the last one is very important, which directly determines the cleanliness of the bottle flakes. [0003] In the current production process, what is generally used in the final cleaning process is as...

Problems solved by technology

Such a tank has a storage time, so the material coming out is relatively dry, but because there is an angle of inclination, this angle should not be too large, if it is too large, it will easily cause blockage at the inclined plate, so the height of the tank is relatively low, and the amount of cleaning water inside Less, so the cleanliness of the material is not good enough

In addition, because some impurities such as wood glue, paste, and small pieces of paper are suspended in the water, and most of the time they float under the water instead of floating to the surface, so it is difficult to remove such floating tanks. Such impurities
