Description

Technical Field

[0001] The utility model relates to the field of waste cutter head recycling, in particular to a device for separating heavy metals from waste cutter heads. Background Art

[0002] Cemented carbide inserts are made of cemented carbide, which is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. In particular, its high hardness and wear resistance remain basically unchanged even at a temperature of 500°C, and it still has a high hardness at 1000°C.

[0003] During mechanical processing, alloy tool heads need to be recycled and screened. Currently, many enterprises or self-employed individuals separate them manually by placing tool heads in liquid mercury to make part of the tool heads dissolve in the mercury, sink in the mercury, or float on the mercury. This is used to screen the tool heads and separate different tool heads. However, since mercury is toxic, it is very harmful to people during operation, and the efficiency is low, and the loss of mercury volatilization is large. Therefore, a device for separating heavy metals from scrapped tool heads is proposed. Utility Model Content

[0024] Example

[0025] Please refer to Figure 1-Figure 6As shown, the utility model provides a device for separating heavy metals from scrapped tool bits, the device comprises an isolation box consisting of a lower box body 1 and an upper box body 3, the internal mercury is isolated from the outside by the isolation box, a sealing rubber is arranged between the lower box body 1 and the upper box body 3, and a blowing drying device 6 is arranged between the lower box body 1 and the upper box body 3, the lower box body 1 and the upper box body 3 are fixed together by the blowing drying device 6;

[0026] like Figure 1-Figure 5 As shown, a mercury box 10 is fixed inside the lower box body 1, and a vibrating screen and other structures are arranged inside the mercury box 10 to enable the mercury box 10 to shake and accelerate the sedimentation and dissolution of the cutter head. Mercury is contained inside the mercury box 10, and a partition 11 is fixed to the middle part of the mercury box 10. The upper part of the mercury box 10 is divided into two areas by the partition 11. A Z-shaped conveyor belt 8 is fixed inside the mercury box 10, and a first baffle 9 is arranged on the outer side of the Z-shaped conveyor belt 8. The cutter head sunk to the bottom is pushed out by the first baffle 9. The bottom end of the Z-shaped conveyor belt 8 is located in one area, and the inclined end of the Z-shaped conveyor belt 8 is located in another area, and the screen of the cutter head The selection and separation are both located in the area where the lowest end of the Z-shaped conveyor belt 8 is located. Through the action of the partition 11, the floating cutter heads are all located in the screening area and will not float to the other side so that the first baffle 9 on the outside of the Z-shaped conveyor belt 8 can convey the floating cutter heads out. A sinking cutter head recovery box 2 is inserted into the outside of the lower box body 1. A sealing structure is provided between the lower box body 1 and the sinking cutter head recovery box 2 so that mercury will not escape from the gap between the lower box body 1 and the sinking cutter head recovery box 2 after volatilization. At the same time, the sinking cutter head recovery box 2 is located below the highest point of the Z-shaped conveyor belt 8. After the Z-shaped conveyor belt 8 conveys the cutter head waste, it will fall into the interior of the sinking cutter head recovery box 2.

[0027] like Figure 1-Figure 6 As shown, a floating object pushing structure is fixed on both sides of the mercury box 10, and the floating object pushing structure includes a pushing cylinder 14 fixed on the front and rear sides of the mercury box 10, and the telescopic end of the pushing cylinder 14 points to the direction of the screening area of ​​the mercury box 10, and an L-shaped plate 16 is fixed to the telescopic end of the pushing cylinder 14, and a vertical guide rod 17 is penetrated on the top surface of the L-shaped plate 16, and a second baffle 15 is fixed at the bottom end of the two vertical guide rods 17, and an elastic member 18 located between the second baffle 15 and the L-shaped plate 16 is sleeved on the outer side of the vertical guide rod 17, and a limiting block 19 is fixed on the top of the vertical guide rod 17, and the limiting block 19 is located above the L-shaped plate 16, and an inverted V-shaped plate 12 is fixed on the side of the mercury box 10 on the side opposite to the sinking cutter head recovery box 2, and a floating cutter head recovery box 13 is inserted into the side of the lower box body 1 adjacent to the inverted V-shaped plate 12, and the floating cutter head recovery box 13 is located below the inverted V-shaped plate 12;

[0028] By extending the push cylinder 14, the push cylinder 14 pushes the second baffle 15 to move. Since the outer side of the vertical guide rod 17 is covered with an elastic member 18, the elastic member 18 pushes the second baffle 15 downward. When the second baffle 15 contacts the inclined edge of the inverted V-shaped plate 12, as the push cylinder 14 continues to extend, the elastic member 18 is retractable, so that the second baffle 15 can move upward. At this time, the second baffle 15 is in close contact with the inclined edge of the inverted V-shaped plate 12. As the push cylinder 14 continues to extend, the cutter head is pushed out.

[0029] like Figure 1-Figure 5 As shown, a blowing drying device 6 is fixed to the inner top wall of the upper box body 3, and the blowing drying device 6 is located above the highest end of the Z-shaped conveyor belt 8, and a one-way air inlet pipe 4 is fixed to the outer top surface of the upper box body 3, so that the internal air will not escape in the reverse direction, and a sealing upper cover 5 is fixed to the top surface of the upper box body 3, and the sealing upper cover 5 has a sealing structure, and the sealing upper cover 5 is located directly above the screening area of ​​the mercury box 10, and a hopper 7 is fixed inside the upper box body 3, so that the waste blade head is introduced into the screening area of ​​the mercury box 10 through the hopper 7, and a ventilation filter device 20 is fixed to the outer side of the air outlet of the lower box body 1, and the mercury vapor ventilated out can be filtered through the ventilation filter device 20;

[0030] The staff wears a gas mask, opens the sealed upper cover 5, and pours the unclassified cutter heads into the interior of the upper box body 3 through the sealed upper cover 5. In order to ensure the safety of the working environment, ventilation should be carried out in time to disperse the small amount of mercury that escapes and enter the mercury through the hopper 7. After sedimentation, the sunken cutter heads are transferred to the sinking cutter head recovery box 2 through the Z-shaped conveyor belt 8, and are air-dried through the blowing drying device 6. The floating cutter heads are pushed into the floating cutter head recovery box 13 through the second baffle 15. At the same time, through the design of the ventilation and filtering equipment 20, the device can form a certain passage, thereby recovering the volatile steam, and enabling the blowing drying device 6 to form a passage with the outside world and work normally.
