The radiator is generally made of a steel frame and is connected to a copper pipe through which cooling water passes, and around the copper pipe is made of aluminum heat radiating fins.

If the radiator used in the automobile and the heat exchanger is discarded, the frame of steel material is manually removed by hand for recycling, and then the remaining copper pipe and the radiating fin are separated or crushed by hand or crusher, The pieces are separated by a separate sorting device.

However, in the prior art, there is a problem in that the efficiency of the work is deteriorated due to the manual operation or the operation by the separate crusher or sorting device in the state where the concrete system capable of performing the crushing operation and the screening operation of the waste radiator is not provided Specifically, in the case of the crushing operation, after the work of removing the frame of the steel material by manual operation is preceded, only the hard copper pipe and the radiating fin are crushed by the crusher in comparison with the frame, and the troubles in the crushing work are accompanied .

The process of chopping (cutting and separating) copper contained in the waste wire is roughly summarized in FIG. 8 based on the technology of KR 10-1158862, KR 10-0704552 and KR 10-0647992. As shown in FIG. 8, the conventional chopper includes a primary cutter for cutting a pulsed wire to a predetermined length, a secondary pulverizer for finely grinding the cut electric wire to form a chip, And a primary sorting machine (dry type) for sorting the copper and the sheath by a vibration and a specific gravity difference between chips that have passed through the cyclone and a separator A second cyclone for blowing off the outer shells from the first sorting machine to extract unreacted copper and a second cyclone for spraying water onto the outer shells of the second cyclone and then separating the copper and the outer shell by vibration and specific gravity difference (Wet type) and a dryer for drying the copper extracted from the secondary sorting machine.

In order to recycle the radiator, using the difference in specific gravity between copper and aluminum, KR 10-1315096 selects a technique for selecting Al and Cu by means of vibration and blowing, KR 10-1471885 uses a technique using vacuum and wind, KR 10-1034941 discloses a technique for selecting Al and Cu as a vibration and suction means, but there are difficulties in separating high purity copper and aluminum.

Since the thickness of the material is higher than that of the pulverized coal, the pulverizing process is important, and the pulverizing process is required several times, and KR 10-1185441 discloses a technique for pulverizing the pulverized radiator.

The above-mentioned conventional techniques have not solved the following problems.

First, there is no countermeasure against the dissimilar metal crushing mixture in which the copper pieces and the aluminum pieces are mixed together, and they are handmade or exported to China.

Second, the separation capacity of copper and aluminum should be increased in the primary sorting machine. At present, the separation efficiency is about 80 ~ 85% of silver purity.

Third, there is a need for a technique to secure 99% or more of the separation ability of the selected copper, aluminum and iron.

The present invention relates to a method of manufacturing a radiator, comprising: a primary crushing step of cutting a radiator in the form of a sprackett gear;

A secondary crushing step of densely cutting the cut radiator pieces after the primary crushing step; A third crushing step of finely crushing the cut radiator piece with a high-speed rotating cutter blade after the secondary crushing step; A scrap storage for storing a scrap shape by providing a sorter input port 1 having a magnet for separating iron at a lower end thereof after the tertiary scrapping step; A primary sorting step for separating by iron; A fourth crushing step of crushing the dissimilar metal in a state where the copper piece and the aluminum piece are mixed at high speed after the primary sorting step; And a second sorting step of separating the scrap supplied from the cyclone storage into copper, aluminum or steel, after the fourth crushing step, The diaphragm 30 of the sorter 100 used in the sorting step is characterized by having at least one mesh screen 32 through which air can pass through one side.

The crusher applied to the primary and secondary crushing stages densely cuts the radiator while rotating at a low speed of 100 to 200 rpm.

The conveyor conveyed from the above step to the next step is omitted.

In the third crushing step, the scrap crushed by the primary crusher and the secondary crusher is crushed finely by rotating at a high speed, and the scrap having a diameter of about 3 to 5 cm can be penetrated through a mesh at the lower end.

After the third crushing step, fine crushed scrap is transferred to and stored in the cyclone reservoir by blowing.

The outlet of the cyclone reservoir is preferably provided with a magnet for separating iron.

The scrap stored in the cyclone reservoir is delivered to the screw conveyor and supplied through the inlet (1) of the sorter (100).

The fourth crushing step is for crushing heavy scrap and copper after the first sorting step, and most of the scrap is a dissimilar metal mixed with copper pieces and aluminum pieces.

In the fourth crushing step, the scrap is crushed ultrafine by rotating at a high speed and a mesh is provided at the lower end to penetrate scrap having a diameter of about 0.5 to 1 cm.

The difference between the primary sorting step and the secondary sorting step is that a plurality of sorting devices are arranged in parallel in the primary sorting step and one sorting device is provided in the secondary sorting step.

3 is a side view of the sorter 100, FIG. 4 is a configuration diagram of the waving plate 30 of the sorter 100, FIG. 5 is a side view of the separator 100 of the preferred embodiment of the present invention, Fig.

The separator (100) used in the sorting step of the present invention comprises a frame (10) holding a certain height from the ground and supporting each component; The lower end of the frame 11 is connected to the vibration shaft 41 to be vibrated. In order to disperse the scrap, at least one mesh screen 32 is provided on one side, A diaphragm 30 including a diagonal projection 33 formed in the direction of the diaphragm 1; An elastic member fastened to the frame 10 and the diaphragm 30 to absorb vibration; A vacuum duct 20 located at an upper end of the mesh screen 32 of the diaphragm 30 for sucking in aluminum; A blow duct 50 disposed at a lower end of the mesh screen 32 of the diaphragm 30 for dispersing scrap; A vibrating part (40) fastened to the vibration shaft (41) for vibrating the diaphragm (30); And an iron collecting part located at an outlet of the diaphragm 30 for separating the iron, thereby separating and discharging aluminum, iron and copper.

The frame 10 has a shaft 11 at one side thereof to fix the vibration portion 40 and supports the vibration shaft 41 and the diaphragm 30. The frame 10 is preferably provided with means for adjusting the height of the vacuum duct 20 and the blow duct 50.

The vibrating unit 40 is constituted by a cam vibration generating unit connected to a rotating motor. The vibration generated in the vibrating unit is shaken by the vibration shaft 41 fastened to the vibration plate 30. The vibration unit 40 vibrates the vibration direction in the rotation direction of the cam so that the scrap moves to the discharge port located at the upper end, and the vibration disperses the scrap uniformly on the vibration plate 30 by the vibration.

The vacuum duct 20 is connected to a suction motor and a vacuum pipe, and is connected to a connector 21 having a jig 22 at a connection portion. The connector 21 is preferably made of genuine material, and the jeep 22 is used for observing the maintenance and vacuum duct inhaling process.

It is preferable that the height of the vacuum duct 20 and the vacuum plate 30 is gradually decreased, and that the height of the vacuum duct is adjusted in the field by the trial and error method.

The blow duct 50 is connected to a blower and a blowing pipe, and the connection part is fastened to a connector 51 having a jig 52. The connector 51 is preferably made of genuine material, and the jeep 52 is used for observing maintenance and vacuum duct sucking processes.

When the air is blown at a constant wind pressure supplied to the blow duct 50, the scrap is floated at a constant height on the diaphragm 30, and thus the vibration of the diaphragm 30 can not be transmitted. Therefore, the wind pressure supplied to the blow duct 50 is supplied irregularly or intermittently instead of a constant blowing effect, thereby dispersing the scrap and improving the efficiency of scrap separation.

It is preferable that the diaphragm 30 is fastened to the frame 10 by an elastic member that absorbs vibration, and is fastened at an inclination angle of 5 to 20 degrees.

In the present invention, the diaphragm 30 is increased four times as compared to the conventional diverter diaphragm area to handle a capacity of 1,500 Kg / h per hour.

In the present invention, it is preferable to dispose the mesh screen in the vicinity of the protruding portion of the diaphragm 30 and the vacuum duct 20 in order to uniformly disperse the scrap in the increased area. Further, a blow duct is disposed under the mesh screen 32 to allow the stacked scrap to float. With the above arrangement, even if the increased area and scrap supplied are increased, the high separation efficiency can be maintained.

The most important feature of the present invention is that the mesh screen (32) is provided with air passing through one side of the diaphragm (30). Further, the mesh screen 32 is disposed at the upper end of the vacuum duct 20 and at the lower end thereof to the blow duct 50.

As shown in FIG. 5, it is an important technology that the present invention exhibits a high separation efficiency as compared with the prior art, in order to uniformly disperse the laminated scrap and to prevent the scrap broken by the iron, copper and aluminum from tangling with each other.

The vacuum suction system of the prior art is an important technology distinguishing from the prior art in that the scrap can be sucked from the upper end of the stacked scrap while the present invention has a structure in which stacked scrap can be lifted by providing the net screen 32 .

The net screen of the present invention provides a high separation efficiency compared to the prior art without a blow. The air is sucked in the vacuum duct, air is also introduced into the mesh screen 32, and the scrap stacked on the diaphragm 30 floats up, so that the collecting ability of aluminum is improved as compared with the existing technology.

Due to the intermittent blowing in the mesh screen 32, the separation and floatation effects of scrap are increased, and the separation efficiency of each material can be improved.

The diaphragm 30 forms a slanting protrusion 33 formed in the direction of the injection port 1 in order to disperse the scrap supplied from the cyclone reservoir.

The protrusions 33 have the effect of evenly dispersing scrap on the diaphragm due to the vibration energy of the diaphragm 30.

The iron collecting part is preferably located at the outlet of the diaphragm 30 to separate the iron.

FIG. 6 is a photograph of a scrap radiator, FIG. 7 is a photograph of aluminum and copper selected through the present invention, and FIG. 9 is an actual photograph of the constituent elements of the present invention.

The greatest effect of the present invention is that, as shown in FIG. 8, it is possible to separate at least 95% of purity of iron, copper, and aluminum without using wet sorting used in a chipping machine for extracting copper from a waste wire.

Radiators are mostly exported to China at low cost because of low efficiency of separation. However, since the purity of materials in recycling differs exponentially with price, high separation efficiency improves the financial condition of the company and it is processed in Korea .
