Description of the Invention: [Technical Fields of the Invention] The method of cultivating the Wei film or coating the metal with a multi-layered simple heat and the method of cultivating the character and regenerating the product from containing one or more thermoplastic resins and impurities The secret of the tree: the material regeneration - the face of Wei Wei, the purpose of correcting the device, the domain, about a shop setting [previous technology] gamma = year ί 'With the synthetic resin as the main raw material, a wide range of petrochemical products are widely used A large amount of waste is discharged from the whole industry. _, because of the waste of this synthetic purpose, there is no record _ recorded _ the nature of f, therefore, when the New Zealand is not, it will mix the soil, when the burning of various heavy metals and poison gas, polluting the air. Therefore, there is a need for a method for regenerating waste of the above synthetic resin which is inexpensive and free from environmental pollution. It is especially difficult to synthesize a resin waste towel. The position is set in cultivated land, which has functions such as preventing water loss and inhibiting weed growth. This feature has recently been widely used. However, since the mulch film is laid on the arable land, a large amount of soil adheres to the mulch film, and the soil adheres tightly to the surface of the mulch film, and it is difficult to remove the soil from the mulch film. Now, a method of regenerating a mulch film which is generally used is disclosed in Korean Laid-Open Patent Publication No. 2002_0034653. According to the above-mentioned published patent document, the conventional method for regenerating a film is as follows: First, the collected medium is chopped into a chopper and cut into a predetermined size, and then the chopped ground film is poured into the washing tank together with water to remove the adhesion. Impurities such as dirt on the mulch film. Then, the mulch film from which the impurities have been removed is put into a dewatering tank for dehydration, and the dehydrated mulch film is put into a hot melt extruder, and is melted by a heater, and discharged from one side. The melted mulch film is extruded into a hole of a predetermined diameter, and at the same time, cut into a predetermined size by a cutting device and pellets are produced. However, in the above conventional film regeneration method, since water is used for washing the film, there is a problem that water quality is contaminated. Further, as described above, it is difficult for water to wash the soil adhering to the mulch film, and it is difficult to produce granules from the mulch film due to the presence of dirt (impurities). In addition, multi-layer films are generally used as food packaging papers. In order to prevent moisture and protect the food from ultraviolet rays, the multilayer film is composed of a film made of a thermoplastic resin such as polyethylene terephthalate, polypropylene, or polyethylene, and a metal (usually aluminum) coated on the film. 201100221 Most of the 211 = was abandoned. The discarded multilayer film is not specially treated, and some of the ρρΖ \ 种 比率 _ _ _ _ hal _ _ hal _ _ _ _ hal _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Poor, can only be used as a low-grade resin product M JS (four) 528646 needle has been recorded in the village layer regeneration method. According to the patent method paste: a step of selectively dissolving a wheel; a difference in specific gravity is a step of selectively performing a surface by a difference in melting temperature; and a step of selectively performing dissolution by an organic solvent. The method for regenerating the above-mentioned multilayer film is decomposed by a chemical solvent, so that the pot process is complicated, the treatment cost is high, and it is not economical. SUMMARY OF THE INVENTION The present invention is directed to a method and apparatus for easily separating one or more thermoplastic resins and impurities from a resin mixture containing one or more thermoplastic resins and impurities. . The inventors of the present invention conducted a method of repeatedly researching the impurities, such as soil, lin, metal, and the like, which are closely adhered to the thermoplastic resin, without using water or a chemical solvent, and the result of the repeated study, the heating of the hull compound is over The temperature of the Weihua temperature is less than the temperature of the igniting, and the fluidity is imparted to the tree 曰 σ 、 and the resin mixture having fluidity (hereinafter referred to as “fluent liquid phase resin mixture”) When the centrifugal separation is carried out, the thermoplastic resin is separated from the impurities. In the present invention, the soil, bribe, metal, etc., which are the main targets of the impurities, maintain the solid phase (s〇lid_e) at a temperature exceeding the melting point of the thermoplastic resin. Usually, the thermoplastic resin is melted, which is a high secret. The impurities of the resin mixture in which the feathers are dispersed in such a high-precision state are not easily used when the conventionally known solid-liquid separation method is used. The thermoplastic resin and the impurities are separated. Thus, the inventors have found that when a rotating body capable of rotating more than 2 rpm is injected into the flowing liquid resin mixture The thermoplastic resin and the impurities are separated into solid phases, respectively. The inventors of the present invention changed the viscosity (poise) of the liquid phase resin mixture flowing by the temperature change and the injection pressure of the liquid phase resin mixture flowing to the rotating body (201100221) Kj/cm2) and/or injection amount (L/min), rotational speed of the rotating body (rpm) (centrifugal force (kgf)), and as a result of observation, the liquid phase injected into the rotating body under predetermined conditions In the resin mixture, the thermoplastic resin becomes a powder form or a fibrous form and floats on the rotating body, and the impurities fall under the rotating body in a fine powder form. In the present invention, the thermoplastic resin is made into a powder form. It is especially important to drop the impurities under the rotating body while floating on the rotating body. If the thermoplastic resin does not float on the rotating body, the powdery or fibrous thermoplastic resin is mixed with the impurities, making it difficult to separate. Or the separation cost will increase. 旋转The rotating system of the present invention, when the injected liquid phase resin mixture is connected to the surface of the rotating body In one instant, the device separates into a solid phase thermoplastic resin and impurities. Therefore, the rotating body of the present invention includes a conical shape in which the tip is cut, a disk shape, a cup shape, a multi-lobed shape, and the like. A method of regenerating a thermoplastic resin from a resin mixture containing one or more thermoplastic resins and impurities, comprising: a step of heating the above resin mixture to form a flowing liquid phase resin mixture; and flowing the liquid phase resin mixture a step of injecting the thermoplastic resin onto the rotating body, and dropping the impurities under the rotating body to separate the thermoplastic resin and the impurities; and collecting the thermoplastic resin. Μ Q An apparatus for regenerating a thermoplastic resin from a resin mixture containing one or more thermoplastic resins and impurities according to the present invention, comprising: a melter, heating and stirring the above resin mixture, raising a temperature above a melting point temperature to obtain a flow Liquid phase resin mixture; leaving ~ separator to make The thermoplastic resin floats on the rotating body from the flowing liquid resin mixture, and the impurities are dropped under the rotating body to separate the thermoplastic resin and the impurities, and the controller controls the centrifugal force and the flow of the rotating body. a viscosity of the liquid phase resin mixture and an amount of the injection into the rotating body; and a collector for collecting the thermoplastic resin, wherein the centrifugal force, viscosity, and injection amount are controlled by the controller to obtain a powdery or fibrous thermoplastic Resin. 6 201100221 The eight-replenishment of the squad is based on the secret, the resin mixture, the pigment and the metal. Therefore, the project is simple and economical, and the monthly thermoplastic resin is purified. Further, according to the present invention, the flow-through liquid phase resin mixture is in contact with the eight compartments of the rotating body, respectively, and is separated from the axis, so that it can be easily separated from impurities and is economical.

(Moltener) The melter (10) of the present invention accommodates the resin mixture introduced into the melting tank (11), and the heat of the woven body oil (12) is added to reduce the aging age. The melting agent (10) of the present invention may be a heat carrier oil, or may be any device which can be heated by a heating body, electrically heated, or a machine. In the H II (1Q) of the present invention, an applicator (13) capable of dissolving the mixture is provided. The lining (13) contributes to the melting of the tree thief, and serves to break up the impurities contained in the resin mixture and uniformly stir them. Since the present invention binds the thermoplastic resin tightly to the thermoplastic resin, it is included in the tree stalk compound. The resin mixture heated to a temperature above the melting temperature has fluidity, and these flowing liquid resin mixtures are transferred to the storage tank (2G) along with the discharge pipe (14). At this time, the flowing liquid phase resin must have a fluidity that can be exhausted at least through the discharge pipe. Since the heater is heated by the heater provided in the discharge pipe (Fig. 4), the flow liquid resin mixture is kept flowing when it is transferred through the discharge pipe.

In order to maintain the fluidity of the flowing liquid resin mixture, a heating skirt is also provided in the above storage tank (2〇). Further, since the impurities dispersed in the liquid phase resin mixture flowing in the storage tank (20) may agglomerate each other, it is preferable to agitate the mixture with a stirrer (21) to homogenize the resin mixture. Further, it is also possible to control the temperature as needed to make the flowing liquid resin mixture have a viscosity in accordance with centrifugation. The liquid phase resin mixture flowing in the storage tank (20) is sent to the centrifugal separator (3〇) by a discharge pipe (22) provided with a heater. (Centrifugal Separator) The centrifugal separator (30) of the present invention comprises at least a rotating body (32), a motor (33) that rotationally drives a rotating body (32), and a powdery or fibrous thermoplastic tree. Moonlight collector (31). The liquid phase resin mixture flowing through the discharge pipe (22) to the centrifugal separator (3) is injected from the nozzle (34) to the rotating body (32). In the present invention, the conical shape in which the tip end is cut is used as a preferred embodiment of the rotating body (32), but as shown in Figs. 3, 4, and 5, a disc shape (321) and a multi-lobed shape may be used. (322) and cup shape (323), etc. The rotating body 02) is not particularly limited as long as it can withstand high temperatures, but it is preferably made of stainless steel or ceramic. The resin mixture injected into the center portion of the rotating body (32) which is rotated at a rapid speed is subjected to centrifugal force, so that relatively large-weight impurities fall under the rotating body in a powder state, and the heat-Q plastic resin having a small specific gravity floats in powder or fiber form. Above the rotating body. The flowing liquid resin mixture has a high viscosity, and a very large centrifugal force is required to separate the impurities dispersed in the highly viscous resin mixture. The present inventors have conceived a method in which impurities are discharged to the lower surface of the rotating body by the presence of impurities in the normally closed phase, and the thermoplastic resin having a relatively small specific gravity floats on the rotating body to separate. In order to easily separate the thermoplastic resin and the impurities from the flowing liquid resin mixture, the inventors conducted a reverse study and found that the solid phase impurities can maintain the solid phase even if they are separated from the resin mixture, and therefore, can be lowered. The fact that it is below the rotating body. Moreover, it has been found that by adjusting the flow of the axial tree merging, the injection pressure of the testator's secret from the nozzle, and the amount of the sister and the centrifugal force of the rotating body, the powder floating on the rotating body can be obtained. Or a fibrous thermoplastic resin. Impurities will fall under the rotating body, and the thermoplastic resin will float above the 201100221 rotating body, the county, _ quality soil (specific gravity of about 28) or Ming (relatively larger than the specific gravity, and thermoplastic resin (according to the type of resin 〇9 to 丨, '', ·) and the thermoplastic resin is separated into powder or fiber. The t weight is relatively small '% of the original reading of the myeloid system, the flow of the rest of the people (five) the fine-grained age-contact - instant 'can be It is separated into thermoplastic resin and impurities. The thermoplastic tree is separated from the secret money, and the collector of the county (31) can effectively separate the __fat from the === In the figure of the present invention, Wei Jicai = Ο 真空 vacuum collection method using a vacuum suction machine, but the collector (31) can only collect the powder or the __ device, which is made by the special ship. The collector (8) collects the financial system of the thermoplastic resin liquid phase resin mixture through the suction port of the collector (8) in a reduced pressure state, and the temperature of the resin mixture is a function of the resin mixture = but it is difficult to control the resin mixture due to the characteristics of the waste. Composition, therefore, In the present invention, the degree of drying of the resin mixture is adjusted in the manner of the temperature of the resin mixture. The temperature of the resin mixture may be installed on the heater (10), the storage tank (2〇), or the row & Other known methods are used for adjustment. In the present invention, the viscosity of the resin mixture is determined by the temperature of the = tree complex to be 3 to l cps of the dryness of the ink for the pen. Further, in the present invention, the injection pressure and/or the injection amount of the liquid phase resin mixture injected into the rotating body can be adjusted by controlling a pump (not shown) or a nozzle (34). Rotation, the centrifugal force as a function of the diameter and the degree of curvature of the rotor, but due to the diameter of the rotating body, the Tongwei is fixed (the diameter of the disk is 200mm in the present invention), therefore, the rotational speed of the rotating body can be controlled Make adjustments. The circumference of the rotating body has an influence on the sharpness of the powdery shape of the thermoplastic tree on the floating body of the floating county. The present invention focuses on the removal of impurities from the thermoplastic resin mixture, and therefore the ambient temperature of the rotating body is kept at room temperature. The degree of dryness of the flowing liquid resin mixture, the injection pressure and/or the amount of injection of the rotating body, and the force of the rotating body can be controlled by the controller (38). The controller (38) of the present invention can be separately disposed in each of the pieces, and can be divided into a degree, a range of force, and a refill amount, a private force, or also 201100221 can be controlled by a controller. Further, the control action of the present invention can be manually adjusted to adjust the injection pressure and/or the amount of injection or the like. Further, in order to monitor the separation state between the thermoplastic resin and the impurities, the present invention mounts the monitoring camera (37)' and monitors it by a monitor (not shown). When the separation of the thermoplastic resin and the impurities is poor as a result of monitoring by the monitor, the separation state can be controlled by the controller (38). The powdery or fibrous thermoplastic resin floating on the rotating body (32) may include a plurality of thermoplastic resins which may be collected by a collector (31). Further, the powdery impurities which are quickly dropped to the underside of the rotating body (32) can be recovered by a valve (36) installed under the centrifugal separator (3). (Resin Storage Tank) A powdery or fibrous thermoplastic resin is collected by a collector and transferred to a resin storage tank (4〇) through a discharge pipe (35). The thermoplastic resin is used in the form of powder (fiber) or pellet form according to the injection molding method. Therefore, the thermoplastic resin collected in the form of powder or fiber by the present invention can be used as a raw material for regeneration in this state. (Hot melt extruder, etc.) When a granular raw material is required, the powdery or fibrous resin is transferred to a hot melt extruder (5G) through a discharge pipe (42). The resin which was extruded in a hot melt extruder (5 〇) was cut into a predetermined size on a cutter (7 〇) by a cooler (6 〇) to become granules. The granules are transferred to the granule storage tank (8 〇) through the discharge pipe (71) * are stored. Here, the drawing symbols 41 and 81 indicate 阙. Hereinafter, a method of separating a thermoplastic resin and impurities from a resin mixture by the above-described reproducing apparatus of the present invention will be specifically described. Example 1 Early use of agricultural / special film using low density polyethylene (l〇w density p〇iyethyiene, LDPE), {As a raw material for the film, most of the use of South Density polyethylene refueling such as 办 〇 p〇iyethylene, HDP E And the pigment of the polyethylene after the sputum is carbon, so it is black. Because the mulch is laid on the arable land, the soil is close to the surface of the mulch, and contains foreign matter such as sand, bracts, and water during the collection process. The collected mulch film is cut into an appropriate size to carry out a pretreatment process of silk or silk. The metal piece can be separated from the chest iron, and the sand is placed on the moving red and removed by vibrating wire. The Lai's state of the sect of the sect of the sect is also omitted. 201100221 After the pretreatment process is completed, the film is then placed in a melter (10) for melting. In the present embodiment, after the mulch film is placed in the melter, the stirrer is used while raising the temperature, and the film is stirred while being melted. At this time, the mulch film is melted into a liquid, and the soil adhering to the surface of the mulch film is pulverized and mixed with the mulch film in a liquid state. The melting temperature of the polyethylene as a raw material of the mantle is about 100 ° C to 135 ° C. However, in order to make the melted film have fluidity, it is preferable to heat the temperature to a temperature lower than the temperature of the ignition point as much as possible. The mulch film having fluidity after being melted (hereinafter referred to as a flowing liquid phase resin mixture) is centrifugally separated by a pump to a centrifugal separator (30). In the present embodiment, the temperature of the liquid phase resin mixture in which PE is a main component is adjusted to a range of 〇 to 200 °C. Here, the main component of the flowing liquid resin mixture is pE, but depending on the characteristics of the waste, a PP or PET film may be mixed. In this case, since the melting temperature of pET is higher than the melting temperature of PE, it is necessary to raise the upper limit of the above temperature. In the present embodiment, the temperature is adjusted so that the viscosity of the flowing liquid resin mixture becomes 3 to 1 〇 c ps. The lower the degree of the liquid phase of the mixture, the more suitable the centrifugal separation, but the resin in the molten state is itself The viscosity is high, and in order to lower the viscosity of the flowing liquid phase resin mixture, the temperature of the resin mixture should be increased, and therefore, the lower limit of the viscosity is preferably set to 3 cps. Further, if the viscosity of the flowing liquid resin mixture is increased, the impurities cannot be separated from the resin mixture, or the rotation speed (centrifugal force) of the rotating body needs to be increased when the impurities are separated. Therefore, the upper limit of the viscosity is preferably set to 1 〇 cps.旋转 In the present embodiment, a rotating body (32) having a diameter of 200 mm is used, and therefore, the centrifugal force generated on the rotating body becomes a function of the rotational speed. In the present embodiment, the rotational speed of the rotating body is set to 2,000 to 20,000 Å, preferably 5, _ to 2 〇〇〇〇, and more preferably 1 〇, _ 2 2, 000 ipm. The rotation speed of the rotating body is adjusted so that the impurities are separated from the flowing liquid resin mixture and the thermoplastic resin floats on the rotating body in a powder or fiber form. Here, the powdery PE can be obtained as the rotation speed of the rotating body is higher. However, in consideration of the safety of the rotating body, it is preferable to limit the upper limit of the rotational speed of the rotating body to 2 〇, φ φπι. In the second example of the present embodiment, the injection pressure injected from the nozzle (34) to the rotating body (3) is adjusted to 3 to 5 kgf/cm. The diameter of the mouthpiece (34) used in the present embodiment is not particularly limited, but it is considered that the diameter of the rotating body is 2 mm, and the size of the county is 1 mm to 4 mm. The injection amount of the liquid phase resin mixture flowing to the rotating body 11 201100221 directly affects the yield of the thermoplastic resin, and thus the function of the main wide pressure 'and' in this embodiment, the domain has a powdery surface ~ 2G L / Min° The temperature is kept at room temperature. ,,,...apply resin, around the rotating body Example 2
