PET bottle flakes automated cleaning equipment

Cleaning and drying of plastic is broken after the necessary process of cleaning process to remove impurities, in preparation for subsequent processing. Currently plastic recycling business waste plastics cleaning mostly using traditional wet cleaning, the cleaning medium is water, that is, with water or water plus detergent for cleaning. Mechanical cleaning can be divided into intermittent wet cleaning, wet cleaning continuous two kinds.

PET bottle washing automation
PET bottle flakes automated cleaning apparatus shown below, the main technical features are: having a certain sorting capability; hot water spray cleaning; partition cleaning, grading filter, to improve the cleaning efficiency of water use.

PET bottle flakes automated cleaning equipment
Automated cleaning equipment consists of two relatively independent unit composed of a vibrating screen to the left of the cleaning means for cleaning PET bottles upfront; the other is on the right there are three relatively independent partition cleaning automatic cleaning device. PET bottle chip first into the shaker vibration cleaning cleaning apparatus for removing larger impurities and foreign matter. Then from the left into the automatic cleaning device through the delivery device, injected into the hot water from the top of the device, the rotation of the screw conveyor PET bottle flakes from the right end of the conveyor, at the same time play a role in turning.
Three separate partitions the lower portion of the tank cleaning wastewater flow filtration device, respectively, three from the left to the right side of the filter device filters into the 400-200Ľm, 200-100Ľm and 100-20Ľm. In order to improve after cleaning water use efficiency, new clean hot water from above the partition means rightmost injected, after cleaning the tank bottom to collect, process and then filtered from the cleaning partition into the middle of the spray, collected in the bottom of the tank again filtration, washing and finally from the leftmost partition injected. Partition leftmost cleaning tank washing water collected below the vibrating screen directly to the cleaning apparatus used for cleaning water.

Integrated continuous cleaning system
Integrated continuous cleaning systems (such as AMUT - WASHING SYSTEM A Mute washing line), and consists of strong washing and rinsing processes. In strong wash step, the friction material washing machine cleaning. Cleaning action is by rotating paddle in strong friction between the debris of implementation. Material feeding is an ongoing process not adjustable, but by adjusting the friction material can be controlled washing machine in which the residence time. In the absence of noise, there is no need to build soundproof room. Friction washing machine out of the water, the paper contains contaminants filtered back to be used in the process.
After strong wash step, there are two order of rinsing tank start rinsing step. By rinsing separated light contaminants (such as paper, non-polyolefin thermoplastics, etc.). Material from the bottom of the tank into the rinse efficient rinse. Light to filter out pollutants, polyolefin materials were floating away. The rinsing tank is also equipped with automatic extraction means and the filtrate was extracted heavy plastic. After a mixed plastics by the centrifugal drying apparatus to store large package. Cleaning part is fully automatic, controlled by the control cabinet.

Decanter sorting, cleaning equipment integration
Decanter sorting, cleaning equipment integration of the overall technical features are: the use of clean water to maintain the flow of the mixed plastic waste in the gravel, metal, glass, paper removal, while the waste plastics will enter the next step of cleaning materials and recycled polystyrene, and in the process, maintain low water consumption, while reducing the wear of the hard material to the apparatus.

Decanter waste plastic sorting, integrated schematic cleaning equipment
Seen from the figure, the integrated device comprises two stirring screw conveyor, a drain line into the system, a feed inlet port and three material settlement. Impurities from waste plastics charging port on the left side of the join, rotary stirring screw conveyor through two two, while transport equipment to the right side, while the water in the cleaning implement.

In this process, the material according to density differences, settlement will take place in a different location of the device. Corresponding to the different materials of the settlement location, device settings, three material settlement mouth. Settlement Settlement for the left side of the mouth gravel, glass, metal and other heavy density materials, settling lower port to connect a screw conveyor for discharging sediment from settling mouth water. Central settlement mouth for pulp slurry sediment, slurry-like substance can not be used due to the auger output, directly connected to the central settlement mouth discharge pipe. The right of settlement mouth for collecting waste plastic particles and debris, settling a port connected to the lower end of the same screw conveyor for discharging sorting, waste plastic material after cleaning.

Centrifugal separation, washing, dewatering equipment integration
Based on conventional centrifuge technology developed by the centrifugal cleaning, sorting, and dewatering integration of waste plastics processing equipment, its technical features are: mixed waste plastic debris will need to deal with in a cleaning water or cleaning fluid, using a high-speed centrifuge rotation of the liquid and waste plastic materials Shuaixiang centrifuge tube wall. Depending on the difference in specific gravity and waste

plastic washing liquid to achieve separation.
Cleaning fluid containing mixed waste plastics cleaning equipment and EPS recycling machine from the left end of the shaft central centrifugal inflow pipe at the outlet of the central outflow to a centrifuge rotor centrifugal chamber under the effect of centrifugal force thrown towards the cylinder wall. In this process, the proportion is greater than the cleaning liquid waste plastic material will be concentrated in the vicinity of the cylinder wall, while the proportion is less than the cleaning liquid waste plastic material in the inside of the cleaning liquid. Spiral centrifuge rotor on the transport of waste plastic materials play a role in specific gravity of the material being conveyed to the right end of the screw conveyor outlet device, a small proportion of the material being conveyed to the left of the exit device. The cleaning liquid is discharged through a centrifuge to remove the material outlet.
