Detailed Description
Referring to fig. 1, 2 and 3, a construction waste soil classifying device includes a feeding hopper 11, a cylinder 12, a first conveyor 21, a second conveyor 22, a third conveyor 23, a first blanking hopper 24, a second blanking hopper 25 and a third blanking hopper 26. The cylinder 12 is axially inclined, that is, it is in a posture that one end of the cylinder is higher than the bottom of the cylinder. The barrel body of the axial lower part of the barrel body 12 is of a net structure with meshes 121, and a rotary cutter 13 which is provided with blades and can be driven to rotate is arranged at the central axis in the barrel of the axial upper part of the barrel body 12 and is used for crushing the dregs in the barrel body. A discharge hole 122 capable of guiding out the slag soil in the barrel is arranged on one end diameter surface of the axial lower part of the barrel 12. The feed hopper 11 is arranged at one end of the axial high part of the cylinder 12 and is communicated with the cylinder 12, and the original muck enters from the feed hopper 11 and then enters the cylinder 12 under the inclined guidance of the cylinder 12 and slides from the high part to the bottom. The first conveyor belt 21 is disposed just below the mesh structure of the cylinder 12 for receiving the screened soil (screened soil can be used as soil) with smaller particle size formed by falling from the mesh of the cylinder 12, and generally, the conveying direction of the first conveyor belt 21 is parallel to the projection of the central axis of the cylinder 12 on the plane of the first conveyor belt 21, so as to receive the screened soil from the cylinder 12 as much as possible. The first blanking hopper 24 is provided below the conveying front end of the first conveyor belt 21 for collecting the screened soil. The second conveyor belt 22 is provided directly below the discharge port 122 of the cylinder 12, and receives the large-volume soil that cannot fall through the mesh 121 but can fall through the discharge port 122. The third conveyer belt 23 is arranged obliquely, and at least part of the conveyer section is positioned right below the second conveyer belt 22; specifically, the conveying leading end of the second conveyor belt 22 is located directly above the third conveyor belt 23, and one end of the third conveyor belt 23 is lower than the second conveyor belt 22 and the other end is higher than the second conveyor belt 22. The second drop hopper 25 is located below the conveyance rear end of the third conveyor belt 23. The third drop hopper 26 is located below the conveying front end of the third conveyor belt 23. The third conveyer belt 23 can receive the large-size dregs falling from the front end of the second conveyer belt 22 above and transport the dregs on the third conveyer belt 23, and because the inclination angle of the third conveyer belt 23 is large, the heavy dregs such as bones and the like can slide down to fall into the second blanking hopper 25 due to the automatic gravity, and the light dregs such as branches, roots and the like can be transported upwards and finally fall into the third blanking hopper 26. Typically, the axial length of the axially lower portion of the barrel with the mesh 121 is greater than the axial length of the axially upper portion of the barrel without the mesh.
The rotary cutting tool 13 includes a central rotating shaft 131 and a plurality of sets of blades 132 fixed to the central rotating shaft 131, the plurality of sets of blades 132 are arranged at equal intervals along the axial direction of the central rotating shaft, and each set of blades 132 is arranged at equal intervals around the circumferential direction of the central rotating shaft 131. The drum 12 may be a drum that can be driven to rotate. The rotation directions of the roller and the rotary cutter 13 are opposite, so that the crushing strength and the crushing efficiency of the dregs in the barrel 12 can be improved. Specifically, in the present embodiment, three sets of blades 132 are provided, each set of blades 132 has four blades, the four blades are arranged around the circumference at intervals of 90 degrees in pairs, and the blades 132 are in a plate type or a paddle type. The blade 132 is connected with the central rotating shaft 131 through a bolt, so that the blade 132 is convenient to replace.
Referring to fig. 1 and 2, two sides of the first conveyor belt 21 perpendicular to the conveying direction are respectively connected with a guide side plate 27, and the two guide side plates 27 and the first conveyor belt 21 form a trapezoidal groove for receiving the screened soil falling from the cylinder 12. The guide plate 27 is provided to collect the soil sifted down from the drum 12 onto the first conveyor belt 21. The guide side plates 27 may be provided with heaters 28 for raising the temperature of the guide plates. By heating the guide plate 27, the soil on the guide plate 27 can be more easily peeled off from the guide plate 27, and the accumulation of the soil on the guide plate 27 can be prevented.
In this embodiment, there are several discharge ports 122, and the discharge ports 122 are arranged at intervals along the circumferential direction on an end diameter surface of the axial lower portion of the cylinder 12. For large-size dregs, the dregs which can not be filtered out through the meshes are discharged out of the cylinder 12 from the discharge hole 122 under the inclined guiding action of the cylinder 12.
Referring to fig. 2, the device further comprises a nozzle 30 capable of spraying high-pressure gas, the nozzle 30 is connected with an air compressor, the nozzle 30 is arranged above the cylinder 12, the nozzle 30 has a nozzle opening facing the mesh 121 of the cylinder and can move back and forth above the cylinder 12 along the axial direction of the cylinder 12, and the nozzle 30 can spray the whole mesh area of the cylinder 12 along with the rotation of the cylinder 12. Preferably, the nozzle 30 is directed toward the mesh 121 and is aligned with the first conveyor belt 21, and the mesh 121 and the inside of the cylinder 12 are prevented from being clogged by blowing the high-pressure gas into the cylinder 12 through the nozzle 30.
In this embodiment, the size of the mesh 121 on the cylinder 12 is set to 10mm to 40mm, and the inclination angle of the third conveyor 23 is set to 25 degrees to 40 degrees. The inclination angle of the cylinder 12 is set to 15 degrees. The inclination angle of the cylinder 12 is adjustable as necessary.
The construction waste soil classification device of the embodiment has the following classification processes: the original muck is poured from the hopper 11, then enters the cylinder 12 under the inclined guidance of the cylinder 12 and slides from the high part to the bottom, in the sliding process, the original dregs are firstly crushed and refined by the rotary cutter 13 at the high part of the cylinder 12, then sieving the waste soil through the mesh 121 at the bottom of the cylinder 12, forming the sieved soil by the waste soil with smaller particle size, falling from the mesh 121 onto the first conveyer belt 21 and being conveyed to the first hopper collection 24 by the first conveyer belt 21, continuously sliding the waste soil with larger size down to the discharge port 122 at the bottom of the cylinder 12 and falling from the discharge port 122 onto the second conveyer belt 22, conveying the waste soil with larger size onto the third conveyer belt 23 by the second conveyer belt 22, due to the inclined arrangement of the third conveyor belt 23, heavy slag soil with heavier weight slides to the second hopper 25 under the action of self gravity, and light slag soil with lighter weight is conveyed to the third hopper 26 by the third conveyor belt 23.
The above description is only a preferred embodiment of the present invention, and therefore should not be taken as limiting the scope of the invention, which is defined by the appended claims and their equivalents.
