うに、ハンドル２〕・〜・２６１：よっで回動可能(Industrial Application Field) The present invention involves sorting and separating synthetic resin materials for recycling from electric wire scraps that are a mixture of various metals and synthetic resin materials, and recycling synthetic resin materials for recycling purposes. Electric wire scrap transferred to processing T 0) Recycling pre-treatment 40th item: Related 7 ] Conventional σ) Technology) Electric wire production Gluing and laying] Electric wires of various sizes and lengths 0) Cutting on motorcycles, etc. C. In other words, a lot of wire scrap is generated. This electric wire scrap σ) contains J11
There are some things that can be done raw and reused. PVC resin, which is a typical material for insulating materials, can be reused. Therefore, various 0 synthetic resin fees were mixed together.
There is a recycling pre-treatment device for electric wire scraps that separates vinyl chloride resin and other synthetic resin materials for recycling from wire scraps and transfers them to the recycling process. Figure 4 shows the overall configuration of a conventional regeneration pre-treatment device.
Material input hopper 14, cyclone dust collector 2, cleaning mixer 3. Wire mesh conveyor 4, metal recovery machine 5, specific gravity separation water tank,
From screen roller 21 conveyor 7, centrifugal dehydrator 6, intermittent dryer 9, blower] 0, filter 1]! being intimidated. In this conventional regeneration pre-treatment device, the air inside the cyclone dust collector 2 is suctioned at a predetermined pressure by a blower 10 through a pipe 12 and a filter 11. For this reason, a pipe 13 connecting the material input hopper 1 and the mill dust collector 2L is installed.
A high-speed air current is flowing in the direction of arrow A. Then, the electric wire scraps are put into the material input hopper 2. The electric wire scraps are fed under pressure into the cyclone dust collector 2 through the piping 3 with an air flow at a crystal velocity. Inside the Zyclone Sa machine 2, a rotating airflow is generated by the suction airflow to the piping 2, so the electric wire scraps that are fed into the cyclone dust collector 2 have dust deposited on their outer surface due to the rotating airflow. Separated. This dust comes from five directions 1-
However, since the six wire scraps have a certain weight, they fall in the direction of D and are sent to the cleaning mixer 3 disposed below the cyclone dust collector 2. The cleaning mixer 3 cleans the fallen electric wire scraps with water or a cleaning liquid mixed with detergent, and discharges them from the output hopper 14. Discharge hopper 14 height 0'l”
Since a wire mesh conveyor 4 is disposed on one side, the cleaned electric wire scraps are transferred to a metal recovery machine 5 by the wire mesh conveyor 4. 1 Metal same number machine 5, the specific gravity separation water tank 6 side is low or 0, and water is flowing towards this lower side in the direction +i. 2, as shown in the enlarged perspective view of Fig. 5, towards the 71 stream side.

It is configured. Therefore, when the electric wire scrap is transferred to the metal recovery machine 5, the metals such as copper wire, which are heavier than the synthetic resin material, sink to the metal pool] -5 to 20, and the ballast materials, etc. σ] comparison Light substances are swept away toward the specific gravity separation water tank 6 by the force of the water flow σ]. For the metals that have sunk in the metal reservoirs υ15-20, turn each metal reservoir 15-20 upside down using the handles 21-26. :' Take out IJ by rotating. As shown in the enlarged cross-sectional view of FIG. The part passes through the entrance of the screw conveyor 7. For this reason, when relatively light substances such as synthetic resin materials are transferred from the gold 91 collection machine 5, water 27
Lighter substances such as bound paper float on the water surface and are discharged from the discharge port 28 in this floating state. However, synthetic resin materials such as vinyl chloride sink in water and reach the inlet of the screw conveyor 7, and the resin is discharged by the screw 29 of the screw conveyor 7 and discharged from 130.

For example, vinyl chloride is separated and extracted. The separated and extracted specific synthetic resin material is dehydrated in a centrifugal dehydrator 8, then transferred to a rotary dryer 9 and dried with radiant heat from a gas burner 31.

[Problems to be Solved by the Invention] However, according to the above-mentioned conventional configuration, cleaning, separation of metals, separation of the target synthetic resin, dehydration, and drying are each performed by independent equipment. There was a problem in that the entire device was large-scale and a wide area of land had to be secured. Furthermore, since the metal recovery machine 5 using a metal reservoir is used to recover metals, the water must be temporarily stopped and the accumulated metals must be recovered before the metal reservoir becomes full. For this reason, there was a problem that the processing was intermittent and the efficiency was poor. Furthermore, the separation effect varies depending on the amount and flow rate of water flowing downstream in the metal recovery machine 5, and metals may be mixed into the synthetic resin material to be recycled, and the purity of the synthetic resin material obtained from the outlet of the dryer 9 may be insufficient. There was a problem that it did not go up. The present invention was made in view of the above circumstances, and its purpose is to efficiently, without requiring a wide range of land,

The sorting and stirring tank is provided with a plurality of discharge ports located at heights corresponding to the differences in specific gravity between the plurality of substances to be sorted and separated and the liquid, and the synthetic resin material to be recycled is discharged from one of the discharge ports. It can be configured to be removed from the outlet. Further, it is preferable that the stirring blade forms a downward vortex flow in the tank. Further, it is preferable that an obstacle plate is provided on the upper inner wall of the sorting and stirring tank to restrict the movement of substances with low specific gravity toward the bottom of the tank. (Function 1 According to the above configuration, the scale of the equipment is significantly reduced, as electric wire scraps are cleaned and the synthetic resin material for recycling is separated from other substances based on the difference in specific gravity in one sorting and stirring tank. Therefore, it does not require a large area of land.In addition, the separated synthetic resin materials and other substances for recycling are automatically discharged, making continuous operation possible and significantly improving treatment efficiency. [Example] Examples of the present invention will be described below. Fig. 1 is an overall configuration diagram showing an example of the present invention. In the figure, 1 is a material input hopper into which electric wire scrap is input; 40 is a screw conveyor that sends the electric wire scraps input from the material input hopper 1 to the next sorting and stirring tank 41; 41 is a tank containing a liquid with a predetermined specific gravity and a stirring blade; Reference numeral 42 denotes a sorting and stirring tank which cleans the wire scrap by stirring it with a stirring blade, and further sorts and automatically discharges the synthetic resin material for recycling and other substances based on the difference in specific gravity with respect to the liquid.

A hot air blower 46 sends hot air to the dryer 43, and a blower 46 is used to forcefully feed the synthetic resin material that has fallen into the hopper 47 at the outlet of the dryer 43 through the piping 33. FIG. 2 is an enlarged sectional view showing an embodiment of the 1st sorting stirring tank 41. A cylindrical tank 48 with 0, 2 and 4 open is shown in FIG. This tank 4] Jl:t, Jt depending on the weight difference, iJ metals,

5 to dynamically discharge the precipitated metals, etc.,
It has become. . Next, the operation will be explained. First, when electric wire scraps are thrown into the charge input hopper 1 (5-), the electric wire scraps are sent into the sorting and stirring tank 41 through the surikoko ~=] conveyor 41. I? The water 50 is stirred by the stirring blades 52 &, -, and the water 50 is stirred in the tank 4.
A vortex 54 directed in the direction of force 9 has been formed. koσ〕
Therefore, wire scrap is a whirlpool 54! , ::Yo, te-
(force direction), it tries to be swept away. However, since the synthetic resin material is light, the vortex 54. L, -, pit. "Upper Kahe floating", trying to crawl. Therefore, the synthetic resin material becomes suspended at a water depth position where the buoyant force and the downward thrust of the vortex 54 are balanced, that is, at the water depth position where the resin discharge 056 is set, and in this floating state, the vortex 54 It is washed by stirring. On the other hand, substances such as dust that are lighter than the synthetic resin material float to the water surface, and heavier substances such as metals settle in the sediment discharge port 55. In this way, the synthetic resin of the regeneration 1] target, e.g., vinyl chloride resin, is washed, and dust and metals are removed with water.
They are sorted based on the difference in specific gravity with respect to 0. Then, the selected synthetic resin material for recycling is sent from the resin extraction port 5G to the centrifugal dehydrator 42 through the manually operated valve 58. Yes
Precipitate discharge] Metals precipitated in 55 are automatically discharged #
57 periodically or depending on the amount of precipitated metals [1, 1, 1], the amount of water is dynamically removed. The synthetic resin material for recycling purpose sent to the centrifugal dehydrator 42 is
After being dehydrated in this centrifugal dehydrator 42, it is applied to a vibrating dryer 43 where vibrations are applied (1) by the elasticity of the sublink 59, and in this vibrating state it is dried by the hot air sent out from the hot air blower 45. Ru. Then, it is dropped from the outlet of this dryer 43 into the hopper 47.
Then, it falls further into the pipe 33, and is transferred to the regeneration process by a high-speed airflow in the direction of the arrow I3σ) flowing through the pipe 33 by the blower 4G. As described above, in this embodiment, 1. In the two sorting stirring tanks 42, the electric wire scraps are cleaned and the synthetic resin wires to be recycled are separated from other substances based on the difference in specific gravity, so the scale of the apparatus is reduced to a large scale. Therefore, a large area of land is not required. In addition, since the separated synthetic resin materials and other material for recollection are discharged internally, continuous operation is possible, and processing efficiency is greatly improved. Furthermore, in the sorting and stirring tank 42, 2-TI discharge ports 55.56 ft are installed, each located at a water depth corresponding to the difference between the plurality of substances to be sorted and separated and the water 50.
Synthetic resin materials for recycling purposes and lighter and heavier substances can be accurately sorted and taken out. In addition, the stirring blade 52 of the sorting stirring WI42 is
Since the vortex 54 is formed in the F direction of At times, the air in the hollow part prevents the liquid from floating on the water surface (2), and the time required for cleaning and sorting can be shortened. Figure 3 shows another embodiment of the sorting and stirring tank.
Figure a) is a partially cutaway perspective view, and figure (b) is a cross-sectional view. In the figure, the tank 49 is similar to the configuration shown in FIG. 2, and is supplied with water 50 from a faucet 48, a stirring blade 52 for stirring the water 50, a sediment discharge port 55 for discharging metals, etc.
A resin discharge port 56, an automatic discharge valve 57, and a manually operated valve 58 are provided for discharging the synthetic resin material for recycling. In addition, an obstacle plate 60 having a V-shaped cross section is newly provided on the upper inner wall of the tank 49 to restrict the movement of substances with low specific gravity toward the bottom of the tank. Furthermore, a partition plate 63 is provided that partitions the tank 49 into an outer tank 61 and an inner tank 62 to a depth of approximately 172 degrees from the water surface to the obstacle plate 60. In this sorting and stirring tank 64, wire scraps are dropped into an inner tank 62, where they are washed and sorted in the same manner as in the configuration shown in FIG. The resin is discharged from the resin discharge port 56. However, light substances such as dust float above the obstacle plate 60,
Then, the floating matter collects on the water surface of the outer tank 61 due to the vortex generated by the stirring blade 52, and is discharged from the floating matter discharge port 65 together with the water. Therefore, in this embodiment, the sorting accuracy is better than that of the sorting agitation tank 41 shown in FIG. That is, in the configuration shown in FIG. 2, when electric wire scraps are sent one after another to the tank 49, the floating objects that were floating on the water surface are submerged again by new electric wire scraps, and are converted into synthetic resin materials for recycling purposes. There is a risk that they will be mixed together and discharged from the discharge port 56. However, in the configuration shown in FIG. 3, floating objects on the water surface are collected in the outer tank 61 by the partition plate 63, and are further restricted from moving downward into the water by the obstruction plate 60. That is, dust and other resins that are lighter than the synthetic resin material to be recycled are contained in the outer tank 61. Therefore, it is less likely that resins other than the intended purpose will be mixed into the synthetic resin material to be recycled that is discharged from the discharge port 56, and the sorting accuracy will be improved. In both Figures 2 and 3, the water depth where substances other than metals accumulate is determined not only by the difference in specific gravity with water but also by the amount of water discharged from the discharge port 57, 58 (i.e., by the automatic discharge valve). 57, the opening degree of the manual discharge valve 58) and the rotational speed of the stirring blade 52. Therefore, when trying to take out a different type of synthetic resin material from the resin discharge port 56, it is necessary to The opening degrees of the automatic discharge valve 575 and the manual discharge valve 58 and the rotational speed of the stirring blade 52 may be set so that the desired synthetic resin material is retained. In addition, if there are two or more types of synthetic resin materials to be recycled,
What is necessary is just to provide each outlet at a water depth position according to the specific gravity difference with the water 50. Moreover, although water was used for sorting and separation based on the difference in specific gravity, other liquids may be used as long as they do not chemically change the synthetic resin material. [Effects of the Invention] As described above, the electric wire scrap recycling pre-treatment device of the present invention cleans electric wire scraps in one sorting and stirring tank, and sorts and separates synthetic resin materials for recycling from other substances based on the difference in specific gravity. As a result, the scale of the equipment is significantly reduced. Therefore, a large area of land is not required. In addition, since certain types of synthetic resin materials and other substances that have been sorted and separated are automatically discharged, continuous operation is possible and processing efficiency is greatly improved. In addition, if multiple discharge ports are provided, each located at a depth corresponding to the difference in specific gravity between the multiple substances to be separated and the liquid, the synthetic resin material to be recycled and lighter and heavier substances can be separated. It can be sorted and extracted with high precision. In addition, if the stirring blade of the sorting stirring tank is configured to form a downward vortex, it is possible to speed up the precipitation of heavy substances such as metals, and it is possible to prevent the synthetic resin material for recycling from becoming hollow. The air in the hollow part prevents the water from floating to the water surface, reducing the time required for cleaning and sorting. Furthermore, if an obstacle plate is installed on the upper inner wall of the sorting stirring tank to restrict the flow of substances with low specific gravity toward the bottom of the tank, the sorting accuracy can be significantly improved and highly pure synthetic resin materials for recycling purposes can be obtained. be able to.
