The arrangement of the crushing device 13, the screening device 12 and the first folding conveyor means 15 is balanced on the first low platform trailer 11 to prevent severe unbalance loading of the vehicle from side to side or front to back.

Referring to fig. 4 to 7, in the sorting apparatus 2 according to the embodiment of the present invention, a measuring conveyer 23 is horizontally disposed on the second low platform trailer 21, a feeding machine 24 is disposed above the measuring conveyer 23, and a receiving opening of the feeding machine is communicated with an output end of the first folding conveyer device 15. The measuring conveyor belt 23 is provided with a plastic scintillator detection device 26 and a NaI detection device 210 respectively along the material conveying direction and at the upper part thereof to realize the detection of radioactive elements in the material. Two second folding conveyor belt devices 29 are arranged on the second low flat trailer 21 at the tail end of the material conveying direction of the measuring conveyor belt 23, a material distributing device 28 is arranged above the second folding conveyor belt devices 29, wherein a feed inlet of the material distributing device 28 is aligned with the tail end of the material conveying direction of the measuring conveyor belt 23, material distributing outlets of the material distributing device 28 are respectively aligned with the two second folding conveyor belt devices 29, a control device is used for receiving and processing the material radioactivity measuring result detected by the plastic scintillator detecting device 26 and the NaI detecting device 210, controlling the material distributing device 28 to separate the materials conveyed by the measuring conveyor belt 23, and respectively conveying the separated materials to the next process through the two second folding conveyor belt devices 29. By adopting the sorting equipment 2, the problem that the sorting equipment 2 in the prior art cannot realize full automation when sorting radioactive materials and needs to be manually resident on site for auxiliary operation to further influence the physical health of site workers is effectively solved, and automatic sorting and transportation of radioactive materials are realized. When the second low platform trailer 21 is connected to the main vehicle 5, the sorting device can be moved to any workplace.

The length of the belt of the measuring conveyor 23, which is a flat belt with skirt edges to prevent the bulk material from falling off from both sides of the measuring conveyor 23, is determined according to the space required for the layout of the system.

This equipment during operation possesses two kinds of mode: the intermittent type formula is mainly used for high accuracy sorting operation. The measuring conveyer belt 23 sends the materials to the position below the radioactive detector one by one, then the measuring conveyer belt 23 stops sending the materials, the distributing device 28 is put in place in advance according to the instruction of the control equipment after the materials are measured, then the measuring conveyer belt 23 is restarted to send the materials into the distributing device 28, and the materials are guided to the corresponding second folding conveyer belt device 29.

Continuous type, mainly used for high-speed sorting operation.

In the mode, the separation efficiency of the device for low and medium radioactive materials is not less than 30t/h, and the separation precision is not more than 15 kg. When the equipment works continuously, namely the whole processes of conveying, measuring and distributing are continuous, all devices are required to have better cooperativity and real-time performance, and the equipment is generally set to be in a second working mode by default. The time for the material to be detected to reach the outlet of the distributing device 28 from the position of the detector is accurately calibrated, and the time can be calculated and controlled by a vehicle-mounted embedded control system (PLC) through control equipment, so that the distributing device 28 can quickly reach the specified outlet at a proper time, and the mistaken distribution is avoided (namely, part of the exceeding-standard material is separated onto the exemptable conveyor belt, or the exemptable material is separated onto the exceeding-standard soil conveyor belt).

As shown in FIG. 7, the third feeding hopper 2e is arranged at the feeding hole of the feeder 24, and the metal plate is arranged in the feeding hole of the feeder 24, so that the direction and the speed of the sand can be changed and reduced after the sand enters, and the influence on the service life of the conveyor belt caused by the fact that the sand directly falls onto the measuring conveyor belt 23 from the top of the carriage is reduced. A vibrator 2c is arranged on the outer wall of the feeder 24 to ensure uniform blanking.

The system work flow is as follows: incoming material from the output of the first folding conveyor means 15 enters the feeder 24 from the third infeed hopper 2 e; the feeder 24 uniformly and quantitatively feeds the material onto the measuring conveyor belt 23; the radioactive detector measures the radioactive nuclide species and activity level of the contaminated material passing through the measurement conveyor 23; the control device compares the radioactivity measurement result with a preset threshold value to judge whether the radioactivity measurement result exceeds the preset threshold value or not, and controls the material distribution device 28 to act at a proper moment according to the judgment result so as to guide the materials entering the material distribution device 28 from the measurement conveyor belt 23 to different second folding conveyor belt devices 29 (the materials which exceed the radioactivity measurement result are guided to one second folding conveyor belt device 29 to be output, and the materials which do not exceed the radioactivity measurement result can be guided to the other second folding conveyor belt device 29 to be output), thereby completing the automatic measurement and separation of the parts of the materials.

As shown in fig. 5 and 6, the sorting apparatus 2 further includes a thickness adjusting device 27. The thickness adjusting device 27 is arranged on the measuring conveyer belt 23 and is positioned between the feeding machine 24 and the plastic scintillator detecting device 26. The thickness adjusting device 27 includes a first holder 271, a shutter 272, and a lifting mechanism 273. The first support 271 is in a door shape, and the risers 2712 on both sides of the first support 271 are fixed to both sides of the measuring conveyer 23. As shown in fig. 5, the riser 2712 and the measuring conveyor 23 may be fixed by a bolt, specifically, the front end of the bolt passes through the riser 2712 from the side surface of the riser 2712 and then is disposed in a screw hole in the side surface of the measuring conveyor 23, so that the riser 2712 and the measuring conveyor 23 can be fixed.

The baffle 272 includes a fixing plate 2721 and a stopper 2722. The fixing plate 2721 is parallel to the upper top plate 2711 of the first bracket 271. The top surface of the blocking piece 2722 is connected with a fixing plate 2721, and the surface is perpendicular to the conveying direction of the measuring conveyor belt 23. One end of the lifting mechanism 273 is fixed to the upper top plate 2711, and the other end is fixed to the fixing plate 2721, so that the lifting mechanism 273 drives the baffle 272 to lift. Specifically, the lifting mechanism 273 can drive the baffle 272 to continuously lift. The distance between the lower end surface of the baffle 2722 of the baffle 272 and the upper surface of the measuring conveyor belt 23 is randomly adjustable within the range of 1 mm-100 mm, and the control error is less than or equal to +/-1 mm.

In practical application, the measuring conveyor belt 23 can convey massive materials, granular materials, powdery materials and the like, and at present, when conveying smaller granular materials such as sandy soil to the next equipment for subsequent processing, the materials are expected to be output according to preset thickness, so that the granular materials such as sandy soil are uniformly and quantitatively conveyed to the tail end of the conveyor belt and do not pile up or fall, but the existing conveyor belt equipment cannot convey the smaller granular materials such as sandy soil according to the preset thickness. In the embodiment of the present invention, by controlling the working state of the lifting mechanism 273, the thickness adjusting device 27 controls the lifting mechanism 273 to drive the baffle 272 to lift, so as to adjust the distance between the end surface of the blocking piece 2722 close to the measuring conveyor belt 23 and the upper surface of the measuring conveyor belt 23, where the distance is the preset thickness of the granular material that can pass through the lower end of the baffle 272.

The third motor 2733 is fixed to the upper top plate 2711, the screw 2732 is connected to the output end of the third motor 2733, and the screw 2732 is sleeved with the nut 2731. The fixing plate 2721 is provided with a fixing hole, and the outer wall of the nut 2731 is clamped in the fixing hole, so that the fixing plate 2721 is fixed to the nut 2731, and the baffle 272 is fixed to the nut 2731. At this time, an avoiding opening is formed at the upper side of the middle part of the blocking piece 2722 to avoid one end of the screw 2732 extending out of the fixing plate 2721. The lifting mechanism 273 provided by the embodiment of the application has a simple structure and is easy to realize.

The working process of the lifting mechanism 273 provided by the embodiment of the application is as follows: when the third motor 2733 is controlled to be opened, the output end of the third motor 2733 drives the screw 2732 to rotate forward or backward, and since the nut 2731 is sleeved on the screw 2732, the nut 2731 moves upward or downward relative to the screw 2732, and the nut 2731 is fixed to the fixing plate 2721 of the baffle 272, so that the nut 2731 can drive the baffle 272 to move upward or downward. The height of the baffle 272 can be known by calculating the number of rotations of the third motor 2733 and converting the number of rotations into the height of the driving nut 2731. In practical applications, the third motor 2733 is a servo motor, and the screw 2732 is driven by the servo motor to rotate, so that the distance between the end surface of the separation blade 2722, which is close to the measurement conveyor belt 23 of the conveyor belt device, and the upper surface of the measurement conveyor belt 23 can be continuously adjusted. The servo motor can ensure that the control speed and the position precision are very accurate, the rotating speed of a motor rotor is controlled by an input signal and can quickly respond, the servo motor is used as an executing element in an automatic control system and has the characteristics of small electromechanical time constant, high linearity and the like, and the received electric signal can be converted into the angular displacement or the angular speed on a motor shaft to be output, so that the control of the lifting height of the baffle 272 driven by the lifting mechanism 273 can be quicker and more accurate.

Of course, the lifting mechanism 273 may further include a hydraulic cylinder, a cylinder body of the hydraulic cylinder is fixed to the upper top plate 2711 of the first support 271, and the telescopic rod is fixed to the fixing plate 2721 of the baffle 272, so that when the hydraulic rod extends, the baffle 272 can be driven to lift.

Because the bayonet socket on the fixed plate 2721 is located to the outer wall card of second slider 2742, thereby it is fixed with fixed plate 2721 to set up second slider 2742, when baffle 272 goes up and down, second slider 2742 slides from top to bottom along the extending direction of first guide post 2741, thereby make fixed plate 2721 slide from top to bottom along the extending direction of first guide post 2741, and then make whole baffle 272 slide from top to bottom along the extending direction of first guide post 2741, guiding mechanism 274 that this application embodiment provided can realize making the lift of baffle 272 more stable, and make baffle 272 go up and down along the extending direction of first guide post 2741. In addition, in practice, because the baffle 272 needs to block granular materials such as sand to can receive granular materials's long-term impact force, and then lead to the baffle 272 to warp, the distance between separation blade 2722 and the conveyer belt that makes up for a long time is inaccurate, and because the both ends of first guide post 2741 are fixed with the top surface and the bottom surface of mounting groove respectively, can make the both ends of baffle 272 fixed, and then make baffle 272 can bear granular materials' long-term impact force and be difficult for taking place the deformation.
