Technical Field

[0001] The utility model relates to the technical field of slag treatment, in particular to a slag metal detection and rejection system. Background Art

[0002] After the incineration of hazardous waste, slag is produced, which contains metal monomers. In the cement kiln co-treatment, the monomer metals will affect the waste addition and cement calcination. The existing process technology equipment adopts manual sorting + magnetic separation + secondary manual sorting technology, and the slag often contains magnetic metals, non-magnetic metals, and wrapped metals. Such materials cannot meet the requirements of cement kiln co-treatment and affect production. In addition, manual secondary sorting consumes manpower and has poor quality stability.

[0003] Cement kiln co-processing is an advanced waste treatment technology that uses the high temperature environment of cement kilns during the cement production process to treat and dispose of various types of solid waste. Cement kiln co-processing technology involves feeding solid waste that meets specific pre-treatment standards into cement kilns. The interior of the cement kiln is characterized by high temperature, long material residence time and high turbulence. These conditions are conducive to the complete decomposition of organic matter in the waste, the effective destruction of harmful components, and at the same time, some of the waste can be used as alternative fuels or raw materials in the production process of cement clinker.

In addition, the removal efficiency is low, which increases the workload of the staff. Utility Model Content

[0045] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0046] Embodiment 1, as Figure 1-18 As shown, this embodiment provides a slag metal detection and rejection system, including a first conveying device 100, a second conveying device 200 is provided at the bottom of the first conveying device 100, and the first conveying device 100 and the second conveying device 200 are used to convey the slag.

[0049] Furthermore, a collecting frame 307 located at the bottom of the frame 301 is installed on the surface of the shell 304, and the collecting frame 307 is used to collect materials that are out of the magnetic suction range of the magnetic suction system 314. A fixing plate 305 is installed on the surface of the shell 304, and a cleaning brush roller 306 is rotatably connected inside the fixing plate 305. The cleaning brush roller 306 is movably connected to the surface of the conveyor belt 312 to clean it. The rear end of the cleaning brush roller 306 is provided with a second transmission wheel 308, and the rear end of the active transmission roller 310 is provided with a first transmission wheel 311. The surfaces of the first transmission wheel 311 and the second transmission wheel 308 are connected with a transmission belt 309 for transmission.

[0050] Furthermore, the magnetic attraction system 314 is one of an electromagnetic coil and a permanent magnet.

[0051] When the magnetic attraction mechanism 300 is working, the magnetic attraction system 314 attracts and separates ferromagnetic metal substances in the slag through magnetic force, and these metals will be adsorbed on the surface of the conveyor belt 312. The output shaft of the first motor 302 drives the active transmission roller 310 to rotate. During the rotation of the active transmission roller 310, the conveyor belt 312 is driven to rotate.

A distribution box 402 is installed on the metal detector 401, and a control panel 403 is installed on the distribution box 402.

[0054] When the metal detection mechanism 400 is working, the first detection probe 404 detects the slag on the top of the second conveying device 200, and the second detection probe 405 detects the slag near the conveyor belt of the second conveying device 200. The detection data is transmitted to the control panel 403, and the control panel 403 transmits the data to the controller 504 to control the material receiving mechanism 500.

[0055] Furthermore, it also includes a material collecting mechanism 500 , which is installed at the bottom of the second conveying device 200 to collect the slag discharged from the second conveying device 200 .

[0056] The material receiving mechanism 500 includes a material receiving box 501, the top of which is connected to a collecting hopper 502 located at the discharge end of the second conveying device 200, and the surface of the material receiving box 501 is respectively installed with a support plate 503, a controller 504 and a reducer 511, the support plate 503 is connected to the bottom of the second conveying device 200 to support the material receiving box 501, and a second motor 510 is installed on one side of the reducer 511, and the output shaft of the second motor 510 is connected to the input shaft of the reducer 511, and the output shaft of the reducer 511 is installed with a pinion 509, and the pinion 50 The bottom of the material receiving box 501 is connected to a limit frame 513 for rotation, and the limit frame 513 is installed on the surface of the reducer 511. The bottom of the material receiving box 501 is connected to a feeding pipe 514. The surface of the feeding pipe 514 is connected to a rotating tube 507 for rotation through a bearing. The surface of the rotating tube 507 is sleeved with a gear ring 508 meshing with a pinion 509. A plurality of laser reflective heads 506 are installed on the surface of the rotating tube 507. The surface of the feeding pipe 514 is installed with a sensor support frame 512, and the sensor support frame 512 is installed with a laser displacement sensor 505 for detecting the laser reflective head 506.

[0057] When the receiving mechanism 500 is working, the slag enters the receiving box 501 through the collecting bucket 502, and enters the distributing mechanism 600 through the discharging pipe 514 and the rotating pipe 507 for sorting. When it is necessary to change the discharging angle of the distributing mechanism 600, the output shaft of the second motor 510 drives the reducer 511 to work, and the output shaft of the reducer 511 drives the pinion 509 to rotate, and the pinion 509 drives the gear ring 508 meshing with it to rotate, and the gear ring 508 drives the rotating pipe 507 to rotate on the surface of the discharging pipe 514, and the rotating pipe 507 drives the cross-tube 601 at its bottom to rotate, so as to achieve the above-mentioned effect. By changing the unloading position of the second discharge channel 605 and the third discharge channel 608, the rotating tube 507 rotates to synchronously drive several laser reflection heads 506 to rotate, and the laser displacement sensor 505 detects the laser reflection head 506. When the rotating tube 507 rotates to a specified angle, the laser displacement sensor 505 can detect the laser reflection head 506 at the corresponding angle. The detection signal of the laser displacement sensor 505 is transmitted to the controller 504, so that the rotation angle of the rotating tube 507 can be controlled, thereby preventing the slag discharged from the second discharge channel 605 and the third discharge channel 608 from spilling.

The first discharge channel 607 is used to discharge slag containing metal, and the second discharge channel 605 and the third discharge channel 608 are used to discharge slag that does not contain metal.

[0060] Furthermore, the cross-tube 601 is installed at the bottom of the rotating tube 507 and is in communication therewith.

[0061] When the sorting mechanism 600 is working, the slag that has not been completely sorted by the magnetic suction mechanism 300 enters the interior of the feed channel 602. When the slag contains metal, the slag enters the first discharge channel 607 through the feed channel 602, and is discharged from the bottom center of the four-way pipe 601 through the first discharge channel 607. The sorting baffle 606 blocks the slag containing metal to prevent the slag from entering the second discharge channel 605 and the third discharge channel 608. When the slag does not contain metal, the hydraulic cylinder 609 drives the rotating part 610 to move, and the rotating part 610 drives the sorting baffle 606 to rotate. The two sorting baffles 606 rotate relative to each other to close the top of the first discharge channel 607, so that the slag inside the four-way pipe 601 enters the second discharge channel 605 and the third discharge channel 608, and is discharged through the second discharge channel 605 and the third discharge channel 608, thereby realizing the sorting of the slag.
