Description

Technical Field

[0001] This application relates to the field of waste recycling and treatment, and particularly to a recycling management system for construction site waste materials. Background Art

[0002] Construction waste refers to the muck, waste materials, scraps and other waste generated during the construction, laying, demolition or repair of various buildings, structures, pipe networks, etc. by construction, construction units or individuals. These materials are of no help to the building itself, but are substances generated during the construction process and need to be processed accordingly in order to achieve an ideal engineering project construction.

[0003] In the related art, waste collection bins are usually placed at the construction site, and various waste materials are put into them, and are processed and recycled by means of manual screening, filtering, etc. regularly. During the recycling process, the operator first takes out and classifies the materials in the collection bin. The conventional classification is only based on the shape or volume of the materials. The waste materials with large volume are separated and then crushed, and the waste materials with small volume or in powder or granular form are concentrated for briquetting.

[0004] The above simple classification method has obvious problems of low efficiency, low accuracy and non - fine classification, which in turn leads to poor effects of waste material recycling and utilization. Summary of the Invention

[0022] The following is a further detailed description of the present application in combination with the attached Figures 1-4 drawings.

[0023] An embodiment of the present application discloses a construction waste recycling management system. As Figure 1 shown, it includes a collection box 1 and a classification device 2. The classification device 2 includes a frame 21. A plurality of collection boxes 1 can be set according to on-site requirements, and multiple collection boxes 1 collect waste materials at different positions on the construction site. A placement slot 22 is provided above the frame 21; a processing chamber 23 communicating with the placement slot 22 is opened in the frame 21, and a grading and processing mechanism 3 is provided on the frame 21. The placement slot 22 is for placing the collection box 1, and the waste materials carried in the collection box 1 are discharged into the processing chamber 23 through the placement slot 22. The grading and processing mechanism 3 is used to separate the waste materials according to volume and magnetism.

[0024] As Figure 1 and 2 shown, the collection box 1 includes a box body 12 and a bottom plate 11. The lower part of the box body 12 is open, and the bottom plate 11 is movably connected to the box body 12. The bottom plate 11 is used to close or open the lower opening of the box body 12. The bottom plate 11 is rotatably connected to the box body 12, and the rotation axis is in the horizontal direction. The rotation axis is located at one side edge of the bottom plate 11. One side of the bottom plate 11 away from its own rotation axis and the box body 12 are detachably connected by bolts. When the bottom plate 11 and the box body 12 are fixedly connected by bolts, the plate surface of the bottom plate 11 is horizontal, and the lower opening of the box body 12 is also closed. The bolts are threadedly connected to the side wall of the bottom of the box body 12, the axis of the bolts is in the horizontal direction, and the end of the bolts is inserted into the edge of the bottom plate 11. The bottom plate 11 and the box body 12 maintain a relatively stable relationship, and the collection box 1 collects waste materials normally in this state.

[0025] As Figure 1As shown, when the collection box 1 is placed on the placement slot 22 and the lower opening is opened, the waste materials in the collection box 1 will fall. The materials collected in the collection box 1 include iron wires, steel bars, wooden blocks, bolts and nuts, processing scraps, debris, etc. The classification and treatment mechanism 3 includes an interception component 34 and a filtering component 33. The filtering component 33 is used for gradually filtering the waste materials according to their volumes, and the interception component 34 is used for blocking the long and thin objects such as iron wires, steel bars, and large-sized wooden strips in the collection box 1. The interception component 34 includes an adjustment seat 341 and a plurality of interception rods 342. The adjustment seat 341 is slidably connected to the frame 21 and is located beside the placement slot 22. The sliding direction of the adjustment seat 341 is horizontal. An electric slide is provided on the frame 21 for controlling the sliding of the adjustment seat 341. The plurality of interception rods 342 are connected to the side of the adjustment seat 341 facing the placement slot 22. The length direction of the interception rod 342 is parallel to the moving direction of the adjustment seat 341. An interception hole 121 for the interception rod 342 to pass through is provided on one side wall of the box body 12. After the box body 12 is placed in the placement slot 22, the movement of the adjustment seat 341 can make the interception rod 342 pass through the interception hole 121 and abut against the inner wall of the other side of the box body 12. A blocking plate 13 is movably provided on the box body 12. The blocking plate 13 is used for blocking or opening the interception hole 121. The blocking plate 13 is slidably connected to the box body 12, and the sliding direction is vertical. A blocking bolt 131 is passed through the blocking plate 13. After the blocking bolt 131 passes through the blocking plate 13 and is threadedly connected to the box body 12, the blocking plate 13 and the box body 12 are relatively fixed. At this time, the blocking plate 13 blocks the interception hole 121.

[0026] As Figure 1 and 3 shown, the interception rod 342 is rotatably connected to the adjustment seat 341, and the rotation axis is the straight line where its own length direction is located. A plurality of adjustment gears 347 are rotatably connected to the adjustment seat 341. A single interception rod 342 is coaxially connected to one adjustment gear 347. An adjustment motor is provided on the adjustment seat 341 for driving one of the adjustment gears 347 to rotate. The plurality of adjustment gears 347 are sequentially meshed, so that each adjustment gear 347 can rotate simultaneously, and the corresponding interception rod 342 also rotates accordingly. A plurality of blocking rods 348 are rotatably provided on the side wall of the interception rod 342, and the rotation axis is perpendicular to the length direction of the interception rod 342. A plurality of receiving grooves 3422 are provided on the side wall of the interception rod 342. The length direction of the receiving groove 3422 is the same as the length direction of the interception rod 342. A single blocking rod 348 corresponds to one receiving groove 3422. During the process that the interception rod 342 does not pass through the interception hole 121 or normally passes through the interception hole 121, the blocking rod 348 is located in the receiving groove 3422. When the interception rod 342 passes through the interception hole 121 and the end contacts the inner wall of the box body 12, each blocking rod 348 rotates 90°, and at this time, the length direction of the blocking rod 348 is perpendicular to the length direction of the interception rod 342.

[0027] like Figure 1 and 4 As shown, a feedback groove 3421 is coaxially provided at one end of the intercepting rod 342 away from the adjustment seat 341, and the cross section of the feedback groove 3421 is circular. A feedback slider 343 is provided in the feedback groove 3421 of the intercepting rod 342, and the feedback slider 343 can rotate relative to the intercepting rod 342 and can slide relative to the intercepting rod 342. The feedback slider 343 is rotatably connected to a driving rack 346 at one end thereof facing the adjustment seat 341, and a driving gear 345 is coaxially fixedly connected to the rotating shaft of the blocking rod 348 relative to the intercepting rod 342, and the driving gear 345 is meshed with the driving rack 346, and a feedback spring 344 is connected between the driving rack 346 and the blocking rod 348, and in a natural state, the feedback slider 343 extends from the end of the intercepting rod 342. When the end of the interception rod 342 approaches the inner wall of the box 12, the feedback slider 343 first contacts the inner wall of the box 12, and then the interception rod 342 continues to move, the feedback slider 343 and the driving rack 346 move relative to the interception rod 342, the driving gear 345 rotates, and each blocking rod 348 rotates out from the storage slot 3422, and the length direction of the blocking rod 348 is perpendicular to the length direction of the interception rod 342. Before the bottom plate 11 of the collection box 1 is opened, the blocking plate 13 is first moved to open each interception hole 121, and the adjustment seat 341 moves to allow each interception rod 342 to enter the box 12. The interception rod 342 penetrates and intercepts slender objects such as iron wires, steel bars, and large-sized wooden strips in the box 12. When the end of the interception rod 342 abuts the inner wall of the box 12, the obstruction rod 348 extends to improve the interception effect.

[0028] like Figure 3 and 4 As shown, since the shape of the material intercepted by the intercepting rod 342 in the box body 12 is relatively uncertain, when the intercepting rod 342 rotates, part of the blocking rod 348 is subject to greater resistance, while part of the blocking rod 348 is subject to less resistance; therefore, the intercepting rod 342 and the adjusting gear 347 are coaxially connected for rotation, and a residual torsion spring is connected between the intercepting rod 342 and the adjusting gear 347. After the bottom plate 11 is opened, the adjusting motor is started to make each intercepting rod 342 reciprocate, and different intercepting rods 342 are subject to different resistances, and the rotation conditions are also different. The intercepting rod 342 and the blocking rod 348 stir this part of the material, so that the powdery, granular, and small-volume block materials attached to it can fall more smoothly.

[0029] like Figure 1As shown in the figure, the filtering component 33 includes a plurality of filtering plates 331. The filtering plates 331 are located in the processing chamber 23 and are connected to the frame 21. Filtering holes are formed in the filtering plates 331. The plurality of filtering plates 331 are arranged vertically, and the aperture diameters of the filtering holes on different filtering plates 331 in the direction of gravity gradually decrease, that is, the smaller the volume of the material, the higher its penetrability. The classification processing mechanism 3 further includes a negative pressure fan 31 and a filter cartridge 32. The negative pressure fan 31 is communicated with the processing chamber 23. The filter cartridge 32 is detachably connected to the frame 21 and is located between the negative pressure fan 31 and the processing chamber 23, that is, there is a negative pressure air flow in the processing chamber 23. The filtering plate 331 is rotatably connected to the frame 21. The rotating shaft is located at the edge of the filtering plate 331 and the rotation axis is in the horizontal direction. A vibration spring 332 is connected between the filtering plate 331 and the frame 21. When the falling material impacts the filtering plate 331, the filtering plate 331 vibrates, and the fine powder and granular objects in the material are lifted up and float in the air. Under the action of the negative pressure air flow, such substances move towards the filter cartridge 32 and adhere to the filter cartridge 32. When the weight of the material carried on a single filtering plate 331 is too large, the deformation amount of the vibration spring 332 is large, and the filtering plate 331 inclines at a large angle. Therefore, a plurality of guiding inclined plates 333 are fixedly connected to the inner wall of the processing chamber 23 of the frame 21. A single guiding inclined plate 333 is located between two adjacent filtering plates 331. The guiding inclined plate 333 is located on the side of the filtering plate 331 away from its own rotating shaft, and the side of the guiding inclined plate 333 away from the inner wall of the processing chamber 23 inclines downward. After the upper filtering plate 331 inclines, the material on it slides down to the guiding inclined plate 333, and the guiding inclined plate 333 guides it to the lower filtering plate 331 through its own inclination.

[0030] As Figure 1 shown in the figure, the material of the filtering plate 331 is a magnetically attractive metal. In this embodiment, iron is used. A magnet block 334 is fixedly connected to the filtering plate 331. The magnet block 334 is located on the side of the filtering plate 331 facing away from the collection box 1. When the magnetically attractive metal parts in the material contact the filtering plate 331, there is a high probability of being adsorbed on the filtering plate 331, and the non-magnetic material can continue to fall, thereby realizing the separation of the material.

[0031] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
