Working principle of paper plastic separator
Paper-plastic separator is a machine that separates paper and plastic. With the development of the economy, people have also begun to pay attention to environmental protection. The industry of plastic granule recycling has broad prospects and good benefits, and has been recognized by many people. However, the separation of paper and plastic will bring great benefits to investors. The distress of the traditional separation method is that the investment is relatively large, the pollution is large, and the paper and plastic cannot be separated cleanly. How does the paper-plastic separator separate?
The following SUNY GROUP will give you a brief explanation: The thermal separation method of the paper-plastic separator, that is, the method of realizing the paper-plastic separator by changing the plasticity after heating. There are thermal separation method and hot air flow method for heat distribution. The hot cylinder method is that the separation device is composed of an electrically heated chrome-plated material cylinder and a hollow cylinder (drum) with a scraper inside. The scraper is connected to the wall of the heating cylinder, and the two rotate in reverse. The bottom of the cylinder is connected to a trough. The material is fed from the feeding , once the plastic component in it comes into contact with the heat cylinder, it starts to melt, adheres to the cylinder wall, scrapes it off with a scraper, and falls into the trough. This method can separate more than 90% of the plastic and paper, and the separated plastic contains paper. It is very small and can be controlled below 1%; the hot air flow method is to use the principle that the plastic film shrinks when it is heated and the specific area is reduced to realize the separation of the plastic film and paper. The mixture of film and paper is sent to the heating area, and the heating box can be An agricultural grain dryer, granulated so that its surface area is reduced, is mixed with paper into an air separator where air currents carry the paper out of the mixture, and thermoplastic granules fall into the separator bottom. This method can almost completely separate the plastic from the paper.
The wet separation method of the paper-plastic separator is to send the light materials obtained from the dry separation equipment into the pulverizer, and the pulverized pulp flows out from the small holes on the sorting board, and the remaining plastic is separated from a It is discharged from the outlet, then sent to the dehydrator for dehydration, and then sent to the air separator for separation. The electric separation method of the paper-plastic separator is to feed the mixture of paper and plastic into the separator, which is completed by a vibrating feeder, and falls into the rotating crushing drum, and then the mixture of paper and plastic is sent to the separator The corona zone formed between the wire electrode and the crushing, the paper is attracted to the electrode, while the plastic sticks to the drum, and as the drum rotates, the plastic material falls to its bottom and is collected. Humidity affects the electric The result of the separation method has a great influence. When the humidity of the paper-plastic mixture is 15%, although the paper and plastic can be separated, but because the plastic material will be polluted by a large amount of paper, only when the humidity exceeds 50%, the paper and plastic can be separated. Completely separated and contamination is minimized.
The paper-plastic separation equipment developed and manufactured by SUNY GROUP uses a split bearing body as a casting. Ductile iron is a component used in standard machinery at present. It has good weldability and machinability, and has high impact toughness at room temperature. Moreover, the plasticity is high, the brittle transition temperature is low, and the low temperature toughness is also good. Used as parts that can withstand dynamic and static loads such as high shock vibration and torsion, require high toughness and plasticity, especially parts that require a certain impact value at low temperature. The separating cutter head of the paper-plastic separator is made of giant steel blades made of GB manganese steel, and the wear resistance is several times that of ordinary steel. And the separated pulp and plastic are very clean, plastic can be granulated, paper can be made into pulp, both can realize new value, it is the first choice equipment for making plastic granules and paper pulping. This machine has small footprint, large output, low energy consumption, simple operation and convenient maintenance. If you have more needs to know or consult, please feel free to contact us.
