Description

Technical Field

[0001] The invention relates to a high-temperature pyrolysis device, in particular to a high-temperature pyrolysis device for metal garbage attachments. Background Art

[0002] A large amount of garbage is generated in people's daily life. If these garbage are not treated and discharged directly into nature, it will greatly pollute the environment. Some of these garbage can be reused. Recycling this part of reusable garbage is also a measure to protect the environment. For example, metal cans, metal sheets and other things in the garbage can have their surface impurities removed and can be reused after smelting again.

[0003] The patent with the patent authorization announcement number CN208116379U discloses a daily metal waste heat treatment device, which includes a rotating cylinder, a garbage treatment bin, a smoke filter, a gearbox, a delivery port, a speed sensor, and a temperature sensor. A metal garbage delivery machine is arranged above the base, a delivery port is arranged on the metal garbage delivery machine, a heat carrier inlet is arranged above the metal garbage delivery machine, a rotating cylinder is arranged at one end of the metal garbage delivery machine, a garbage treatment bin is arranged in the rotating cylinder, a high-temperature heater is arranged inside the garbage treatment bin, a chuck is arranged on the rotating cylinder, a temperature sensor is arranged on the chuck, a gearbox is arranged next to the chuck, a saw gear is arranged in the gearbox, and a speed sensor is arranged below the saw gear. When the heat treatment device is in use, the metal waste is first put into the metal waste delivery machine from the delivery port, and the heat carrier enters through the heat carrier inlet. The gearbox changes the rotation speed of the saw gear, and the rotation speed sensor detects the rotation speed of the device. When the drive motor drives the gearbox to rotate, the gearbox drives the saw gear to rotate, and the saw gear cooperates with the groove of the outer ring of the chuck to drive the chuck to rotate, thereby driving the rotating cylinder to rotate, accelerating the melting process of the metal. The high-temperature heater can heat the scrap metal at high temperature. The temperature sensor detects the temperature of the melted metal during the operation of the device. The powerful heater performs the final heating on the metal. The gas released when the metal is melted is discharged into the interior of the flue gas filter through the exhaust pipe. The spray head sprays the high-temperature flue gas to cool it down. The melted molten metal enters the next process through the molten metal transfer mechanism. However, the heat treatment device cannot remove impurities attached to the surface of the heated metal waste, and the subsequent melting of the metal will cause the quality of the molten metal to fail to meet the standards.

[0004] In view of the above problems, the present invention provides a high-temperature pyrolysis device for metal waste attachments, which is capable of removing impurities attached to the surface of heated metal waste. Summary of the invention

A screening mechanism 7 is arranged between the tops of the bottom plates 1 on the left and right sides, and the screening mechanism 7 can shake out impurities attached to the metal waste.

[0036] See also Figure 3The preliminary filtering mechanism 6 includes a fixed shell 601, a first rotating shaft 602, a second rotating shaft 603, a square wheel 604, a pulley 605 and a flat belt 606. Fixed shells 601 are welded on both sides of the left and right sides of the top of the heating box 3. The first rotating shaft 602 is symmetrically rotatably arranged in the two fixed shells 601. The second rotating shaft 603 is rotatably arranged on the back side of the middle part of the two fixed shells 601. Square wheels 604 are arranged on the first rotating shaft 602 and the second rotating shaft 603. The square wheel 604 can shake off the moisture on the metal garbage. The rear end of the first rotating shaft 602 is keyed to a pulley 605, and a flat belt 606 is sleeved between two adjacent pulleys 605.

[0037] See also Figure 4-Figure 5 The screening mechanism 7 includes a placement plate 701, a screening frame 702, a first fixed frame 703, a first servo motor 704, a first turntable 705 and a first fixed shaft 706. A placement plate 701 is slidably arranged between the tops of the bottom plates 1 on the left and right sides, a screening frame 702 is placed on the placement plate 701, and the screening frame 702 can shake out impurities attached to metal waste.

[0038] When it is necessary to heat and remove impurities on the surface of the metal waste, the staff pours the metal waste from the fixed shell 601 into the heating box 3. Under the action of the metal waste, the upper square wheel 604 rotates, and the upper first rotating shaft 602 rotates accordingly. When the metal waste falls onto the middle square wheel 604, the middle square wheel 604 rotates to drive the second rotating shaft 603 to rotate. The upper first rotating shaft 602 rotates through the upper pulley 605 to drive the flat belt 606 to rotate. The flat belt 606 rotates through the lower pulley 605 to drive the lower first rotating shaft 602 to rotate. The lower first rotating shaft 602 rotates to drive the lower square wheel 604 to rotate. Under the action of the collision between the metal waste and the square wheel 604, the moisture in the metal waste can be shaken out for subsequent heating. The shaken-out moisture is then discharged out of the device through the fixed shell 601. After the metal waste is poured into the heating box 3, the staff turns on the heating tube 5, and the heating tube 5 operates to heat the metal waste. The heating is performed to make the impurities on the surface of the metal waste agglomerate. After the heating is completed, the staff turns off the heating tube 5, and then the staff pulls the material baffle plate to slide outward to open the bottom of the heating box 3, and the metal waste falls into the screening frame 702. After it falls out completely, the staff pushes the material baffle plate to slide inward to reset and close the bottom of the heating box 3. After completion, the staff starts the first servo motor 704, and the output shaft of the first servo motor 704 rotates to drive the first turntable 705 to rotate. The rotation of the first turntable 705 drives the placement plate 701 to slide back and forth continuously through the first fixed shaft 706. The placement plate 701 slides back and forth to drive the screening frame 702 to shake, thereby shaking off the impurities on the surface of the metal waste, thereby achieving the purpose of removing the attachments on the surface of the metal waste. After the cleaning is completed, the staff turns off the first servo motor 704 to stop the operation, and then the staff picks up the screening frame 702 to take out the metal waste for collection. After completion, the staff puts the screening frame 702 back to its original position.

[0039] Example 2

[0040] See also Figure 1 , Figure 6 and Figure 7 On the basis of Example 1, it also includes an arc-shaped limit block 801, a screw 802, a sealed shell 803, a second servo motor 804, an impeller 805 and a sealed pipe 806. An arc-shaped limit block 801 is arranged on the top of the heating box 3. The sealed shell 803 is arranged on the left and right sides of the arc-shaped limit block 801 through two upper and lower screws 802. The second servo motor 804 is arranged on the upper part of the sealed shell 803. The impeller 805 is arranged on the output shaft of the second servo motor 804. The impeller 805 can discharge exhaust gas. The rear side of the sealed shell 803 is provided with a sealed pipe 806.

[0041] A large amount of exhaust gas will be generated during the heating process of metal waste. At this time, the staff will connect the external exhaust pipe to the sealed connecting pipe 806. After completion, the staff will start the second servo motor 804. The output shaft of the second servo motor 804 will rotate to drive the impeller 805 to rotate. The impeller 805 rotates to draw the exhaust gas in the heating box 3 through the sealed shell 803 to the sealed connecting pipe 806. Then the exhaust gas is discharged through the external exhaust pipe. After use, the staff will turn off the second servo motor 804 to stop the operation.

[0042] See also Figure 1 and Figure 8 , also includes a transmission block 901, a second fixed shaft 902, a transmission rod 903, a second turntable 904, a third fixed shaft 905 and a connecting rod 906. Transmission blocks 901 are arranged on both sides of the left and right sides of the rear of the placement plate 701. The second fixed shaft 902 is welded symmetrically on the left and right sides of the rear lower part of the heating box 3. The two second fixed shafts 902 are rotatably arranged with transmission rods 903. The lower part of the transmission rod 903 is slidingly connected to the adjacent transmission block 901. The rear ends of the two first rotating shafts 602 at the lower part are key-connected with the second turntable 904. The third fixed shaft 905 is eccentrically arranged at the rear side of the two second turntables 904. The two third fixed shafts 905 are rotatably arranged with connecting rods 906. The outer ends of the connecting rods 906 are rotatably connected to the upper part of the adjacent transmission rod 903.

[0043] The placing plate 701 continuously moves forward and backward, driving the transmission block 901 to move forward and backward. The transmission block 901 moves forward and backward, driving the transmission rod 903 to continuously swing up and down. The transmission rod 903 swings up and down, driving the second turntable 904 to rotate through the connecting rod 906 and the third fixed shaft 905. The rotation of the second turntable 904 drives the lower first rotating shaft 602 to rotate, thereby realizing the rotation of the upper and lower square wheels 604, facilitating material unloading and preventing metal waste from clogging the fixed shell 601. At the same time, it can better shake out the moisture in the metal waste. When the placing plate 701 stops moving, the second turntable 904 stops rotating accordingly.

[0044] See also Figure 1 , Fig. 9 and Fig.10 , also includes a second fixing frame 1001, a lower clamp 1002, a third rotating shaft 1003, a torsion spring 1004 and an upper clamp 1005. The second fixing frame 1001 is welded symmetrically on the left and right sides of the top front side of the placement plate 701. The two second fixing frames 1001 are each provided with a lower clamp 1002 on the upper part, and the two lower clamps 1002 are each rotatably provided with a third rotating shaft 1003. The two third rotating shafts 1003 are each provided with an upper clamp 1005. The upper clamp 1005 cooperates with the lower clamp 1002 to clamp the screening frame 702, and a torsion spring 1004 is wound between the upper clamp 1005 and the adjacent lower clamp 1002.

[0045] When the placement plate 701 slides back and forth, the upper clamp 1005 cooperates with the lower clamp 1002 to clamp the screening frame 702, which can prevent the screening frame 702 from falling off the placement plate 701. When the metal waste needs to be collected, the staff presses the upper clamp 1005 to rotate upward, and the third shaft 1003 rotates accordingly, and the torsion spring 1004 is deformed accordingly. The upper clamp 1005 rotates upward and no longer clamps the screening frame 702. Then the staff picks up the screening frame 702 to collect the metal waste. After completion, the staff puts the screening frame 702 back to its original position, and then the staff releases the upper clamp 1005, and the torsion spring 1004 is reset to drive the upper clamp 1005 to rotate downward and clamp the screening frame 702 again.

[0046] See also Figure 1 , Fig.11 and Fig.12 , also includes a support block 1101, a guide box 1102, a guide pipe 1103 and a valve 1104. Support blocks 1101 are welded to the front sides of the left and right bottom plates 1, and guide boxes 1102 are arranged on the left and right sides of the bottom of the heating box 3. A guide pipe 1103 is arranged between the two support blocks 1101. The end of the guide pipe 1103 is connected to the adjacent guide box 1102, and a valve 1104 is rotatably arranged in the middle of the guide pipe 1103.

[0047] When using this device, the staff connects the external water pipe to the diversion pipe 1103. The collision of metal garbage and the square wheel 604 can cause the water in the metal garbage to be shaken out, and the waste water then flows into the diversion pipe 1103 through the diversion box 1102. Then the staff turns the valve 1104 to open the diversion pipe 1103, and the waste water is discharged through the external water pipe, so that the waste water can be discharged in a centralized manner for the staff to clean up. After use, the staff reverses the valve 1104 to close the diversion pipe 1103.
