Description

Technical Field

[0001] The present invention relates to the technical field of construction site material processing, and in particular to a construction site-based material processing system and method. Background Art

[0002] On-site decomposition of materials (construction waste, etc.) at the construction site is an energy-saving and efficient way of material handling. Figure 1 The figure shows an existing material handling system based on a construction site, which comprises a first material conveyor 1, a crushing and sorting device 2, a second material conveyor 3, and a third material conveyor 4. The crushing and sorting device 2 is used to crush and sort the materials to be processed conveyed by the first material conveyor 1, and to convey the sorted metal materials and other materials to different transportation equipment through the second material conveyor 3 and the third material conveyor 4 respectively.

[0003] Since the crushing and sorting equipment 2 needs to crush all kinds of steel-containing and non-steel-containing materials, its crushing efficiency is very low. This is because steel-containing materials cannot be crushed at high speed. If the material processing efficiency is to be improved, the processing capacity needs to be designed to be very large. However, the crushing and sorting equipment 2 with a large processing capacity is costly and large in size. Even if it can be manufactured, it is generally used in a fixed material processing site and is difficult to transport. It is impossible to move the installation site according to the construction site. Summary of the invention

[0004] The object of the present invention is to provide a material handling system and method based on a construction site to solve the problems existing in the background technology.

[0005] The technical solution of the present invention is as follows:

[0006] A material processing system based on a construction site, comprising a first material conveyor for conveying materials to be processed, a crushing and sorting device arranged at a first direction of the first material conveyor, and a control system, wherein a material sorting device is further arranged between the first material conveyor and the crushing and sorting device;

[0007] The material sorting machine comprises a material sorting platform provided with a corner diverter, and a size detection component and a metal detection component arranged on the upper side of the material sorting platform. Non-reinforced material crushing equipment is also arranged at the second direction and the third direction of the material sorting platform. The non-reinforced material crushing equipment comprises a block material crusher and a plate material crusher.

[0008] The size detection component is used to identify the materials to be processed as block materials and plate materials, and the metal detection component is used to identify the materials to be processed as materials containing steel bars and materials without steel bars;

[0009] The control system controls the corner diverter (whose diversion method is like the swing arm sorter or wheel sorter of the express sorting machine) to divert the materials to be processed based on the detection information of the size detection component and the metal detection component, so that the steel-containing material is conveyed along the first direction where the crushing and sorting equipment is located, and the block material without steel bars (such as bricks, concrete blocks without steel bars) and the plate material without steel bars (such as gypsum boards) are conveyed along the second direction and the third direction where the block material crusher and the plate material crusher are located, respectively.

[0010] When in use, the steel-containing materials, non-steel block materials and non-steel plate materials in the materials to be processed are automatically sorted out and transported to different crushing equipment respectively, so that various materials can be targeted and differentiated for crushing treatment, thereby improving the crushing efficiency; at the same time, the requirements for equipment capacity when processing all materials at the same time are reduced. These crushing equipment can be manufactured separately and can be transferred to the site separately according to the construction site for assembly, which greatly reduces the difficulty of manufacturing and transportation.

[0011] Furthermore, the steel-containing materials on the material sorting table are sent to the crushing and sorting equipment through the fourth material conveyor, the block materials without steel bars (such as bricks, concrete blocks without steel bars) are sent to the block material crusher through the fifth material conveyor, and the plate materials without steel bars (such as gypsum boards) are sent to the plate material crusher through the sixth material conveyor.

[0012] Through the above design, the material handling system significantly improves the efficiency of construction waste treatment and reduces equipment loss by integrating size detection, metal detection and intelligent sorting technology, and ultimately achieves the triple goals of efficient recycling of steel resources, increased aggregate recycling rate and optimized energy consumption of classified crushing.

[0013] Furthermore, the materials crushed by the block material crusher and the plate material crusher are respectively conveyed to the same or different transportation equipment through the seventh material conveyor and the eighth material conveyor.

[0014] Further, the first material conveyor, the fifth material conveyor, the sixth material conveyor, the seventh material conveyor and the eighth material conveyor are all lifting conveyors.

[0015] Furthermore, a punching machine may be provided before the first material conveyor to perform preliminary punching and cutting of materials with excessive size and weight.

[0016] Furthermore, the punching method of the punching machine is hydraulic shear punching. The hydraulic system provides high crushing force, which can easily cope with the rapid cutting of oversized construction waste such as concrete blocks, bricks and stones, and is especially suitable for processing materials with large thickness and high hardness.

[0017] Further, the size detection component adopts at least one of visual detection, laser detection, and ultrasonic detection, and the metal detection component adopts at least one of X-ray detection and ultrasonic detection.

[0018] Furthermore, the jaw crusher can be selected as the block material crusher. This type of crusher has strong crushing capacity, durable equipment, low failure rate, low maintenance cost, and is suitable for rapid crushing of block materials.

[0019] Furthermore, the plate-like material crusher can be an impact crusher, which has high crushing efficiency and uses impact energy to crush materials, and is particularly suitable for rapid crushing of plate-like materials.

[0020] The present invention also provides a material processing method using the above-mentioned material processing system based on a construction site, comprising the following steps:

[0021] S1: Transport the system modules to the construction site and assemble them;

[0022] S2: After starting work, the first material conveyor continuously conveys the materials to be processed to the material sorting table. When the materials arrive at the preset detection area of ​​the sorting table, the size detection component and the metal detection component work together to identify the shape of the materials and whether the materials contain steel bars in real time;

[0023] S3: If the metal detection component identifies the material as containing steel bars, the material containing steel bars is conveyed along the first direction and conveyed to the crushing and sorting equipment for processing through the fourth material conveyor;

[0024] If the metal detection component does not identify the steel bar, and the size detection component identifies it as a block material, the block material without the steel bar is conveyed along the second direction and sent to the block material crusher for processing via the fifth material conveyor;

[0025] If the metal detection component does not identify the steel bar, and the size detection component identifies it as a plate-like material, the plate-like material without the steel bar is conveyed along the third direction and sent to the plate-like material crusher for processing through the sixth material conveyor;

[0026] S4: The crushing and sorting equipment, the block material crusher and the plate material crusher respectively perform differentiated crushing processing on the steel-containing materials, the block materials without steel bars and the plate materials without steel bars, and output the processed materials.

[0027] The beneficial effect achieved by the present invention compared with the prior art is that it can sort the steel-containing materials, non-steel block materials and non-steel plate materials in the materials to be processed, and transport them to different crushing equipment for processing respectively. It can specifically crush the non-steel materials at high speed, reduce the pressure when crushing the steel-containing materials, thereby improving the material processing efficiency, reducing the requirements for equipment capacity when processing all materials at the same time, thereby facilitating the manufacture and transportation of the crushing equipment, and providing conditions for transferring and installing the equipment between different construction sites.

[0034] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0035] Example

[0036] Combination Figure 2 This embodiment provides a material processing system based on a construction site, including a first material conveyor 1 for conveying materials to be processed, a crushing and sorting device 2 arranged at a first direction of the first material conveyor 1, and a control system, and a material sorter is also arranged between the first material conveyor 1 and the crushing and sorting device 2. It should be noted that the crushing and sorting device 2 used in the present invention is not limited to the integrated crushing and sorting device known in the art, and can also be a combined processing device composed of a crushing device and a sorting device, as long as it can crush and sort the steel-containing material.

[0037] The material sorting machine includes a material sorting platform 5 provided with a corner diverter, and a size detection component 6 and a metal detection component 7 arranged on the upper side of the material sorting platform 5. Non-reinforced material crushing equipment is also arranged in the second direction and the third direction of the material sorting platform 5. The non-reinforced material crushing equipment includes a block material crusher 10 and a plate material crusher 12.

[0038] The size detection component 6 is used to identify the material to be processed as block material and plate material, using at least one of laser detection, visual detection, and ultrasonic detection, and in this embodiment, it is laser detection. The metal detection component 7 is used to identify the material to be processed as material containing steel bars and material not containing steel bars, using at least one of X-ray and ultrasonic detection, and in this embodiment, it is X-ray detection.

[0039] The control system controls the corner diverter to divert the materials to be processed based on the detection information of the size detection component 6 and the metal detection component 7, so that the steel-containing materials are conveyed along the first direction where the crushing and sorting device 2 is located, and the block materials without steel bars (such as bricks, concrete blocks without steel bars) and the plate materials without steel bars (such as gypsum boards) are conveyed along the second direction and the third direction where the block material crusher 10 and the plate material crusher 12 are located, respectively. The corner diverter can adopt an existing swing arm sorter or a wheel sorter.

[0040] When in use, the steel-containing materials, non-steel block materials and non-steel plate materials in the materials to be processed are automatically sorted out and transported to different crushing equipment respectively, so that various materials can be targeted and differentiated for crushing treatment, thereby improving the crushing efficiency; at the same time, the requirements for equipment capacity when processing all materials at the same time are reduced. These crushing equipment can be manufactured separately and can be transferred to the site separately according to the construction site for assembly, which greatly reduces the difficulty of manufacturing and transportation.

[0041] As for the transportation of each material from the material sorting table 5 to the crushing equipment, the steel-containing material (such as steel-containing concrete blocks) on the material sorting table 5 is sent to the crushing and sorting equipment 2 through the fourth material conveyor 8, and then crushed by the crushing and sorting equipment 2 to output the steel-containing material (such as steel-containing) and the non-steel-containing material (such as concrete), and are respectively transported to different transportation equipment by the second material conveyor 3 and the third material conveyor 4 located on one side of the crushing and sorting equipment 2; the block material without steel bars (such as bricks, concrete blocks without steel bars) is sent to the block material crusher 10 through the fifth material conveyor 9, and the plate material without steel bars (such as gypsum board) is sent to the plate material crusher 12 through the sixth material conveyor 11, and the materials crushed by the block material crusher 10 and the plate material crusher 12 are respectively transported to the same or different transportation equipment through the seventh material conveyor 13 and the eighth material conveyor 14, and these transportation equipment can be transport vehicles.

[0042] Through the above design, the material handling system significantly improves the efficiency of construction waste treatment and reduces equipment loss by integrating size detection, metal detection and intelligent sorting technology, and ultimately achieves the triple goals of efficient recycling of steel resources, increased aggregate recycling rate and optimized energy consumption of classified crushing.

[0043] In this embodiment, it is preferred that the first material conveyor 1, the fifth material conveyor 9, the sixth material conveyor 11, the seventh material conveyor 13 and the eighth material conveyor 14 are all lifting conveyors, and the fourth material conveyor 8 can be a horizontal conveyor or a lifting conveyor, but this embodiment is preferably a lifting conveyor, which can share the crushing and lifting height with the first material conveyor 1, thereby avoiding exceeding the height limit of the material sorting table 5.

[0044] The block material crusher 10 is a jaw crusher, which has strong crushing capacity, durable equipment, low failure rate, low maintenance cost, and is suitable for rapid crushing of block materials.

[0045] The plate-like material crusher 12 is an impact crusher, which has high crushing efficiency and utilizes impact energy to crush materials, and is particularly suitable for quickly crushing plate-like materials.

[0046] In the case that the size and weight of some materials exceed the tolerance, a punching machine 15 may be arranged before the first material conveyor 1 to perform preliminary punching and cutting of the materials with the size and weight exceeding the tolerance.

[0047] The punching method of the punching machine 15 is hydraulic shear punching. The hydraulic system provides high crushing force, which can easily cope with the rapid cutting of oversized construction waste such as concrete blocks, bricks and stones, and is particularly suitable for processing materials with large thickness and high hardness.

[0048] The shearing blade of the punching machine 15 is a multi-stage progressive cutting to avoid overloading the equipment due to a one-time impact and reduce dust generation.

[0049] Combination Figure 3 The metal detection component 7 can preferably use a dual-energy X-ray detector (such as detecting steel bars wrapped inside concrete) to distinguish metal from non-metal materials by Zeff equivalent atomic number calculation; the size detection component 6 can preferably use a line laser scanning unit and an encoder synchronization module to calculate the material length by contour curve integration. If the thickness is greater than 150 mm and the aspect ratio is ≥2:1, it is marked as a plate-like material; if the thickness is less than 50 mm and the aspect ratio is less than 2:1, it is marked as a block material.

[0050] The present invention also provides a material processing method using the above-mentioned material processing system based on a construction site, comprising the following steps:

[0051] S1: Transport the modules of the material handling system to the construction site and assemble them;

[0052] S2: After starting work, the punching machine 15 performs multi-stage progressive hydraulic shearing punching on the oversized materials, and the processed materials are transported to the material sorting table 5 by the first material conveyor 1;

[0053] S3: Metal detection component 7 and size detection component 6 cooperate to detect:

[0054] When the material reaches the preset detection area of ​​the material sorting platform 5, the size detection component 6 and the metal detection component 7 cooperate to identify the shape of the material and whether the material contains steel bars in real time;

[0055] If the metal detection component 7 identifies the material as containing steel bars, the material containing steel bars is transported along the first direction and conveyed to the crushing and sorting device 2 for processing via the fourth material conveyor 8;

[0056] If the metal detection component 7 does not identify the steel bar, and the size detection component 6 identifies it as a block material, the block material without the steel bar is conveyed along the second direction, and is lifted and conveyed to the jaw crusher for crushing by the fifth material conveyor 9;

[0057] If the metal detection component 7 does not identify the steel bar, and the size detection component 6 identifies the material as a plate, the plate-like material without the steel bar is conveyed along the third direction, and is lifted and conveyed to the impact crusher for crushing by the sixth material conveyor 11;

[0058] S4: After crushing, the materials are processed in different paths:

[0059] The steel-containing material is crushed and sorted by the crushing and sorting device 2, and then the steel-containing material and the non-steel-containing material are output, and the steel-containing material and the non-steel-containing material are respectively conveyed to different transportation equipment by the second material conveyor 3 and the third material conveyor 4;

[0060] The block-shaped crushed materials without steel bars are lifted and outputted via the seventh material conveyor 13, and the plate-shaped crushed materials without steel bars are lifted and outputted via the eighth material conveyor 14, and the seventh and eighth conveyors can be selected to merge into the same or different transport equipment.

[0061] Combination Figure 2 , in step 3:

[0062] The conveying direction of the fourth material conveyor 8 coincides with the first direction. After the material to be processed is identified as a material containing steel bars by the metal detection component 7, the material containing steel bars continues to be conveyed forward to the fourth material conveyor 8;

[0063] When the metal detection component 7 does not identify the bulk material without steel bars and the size detection component 6 identifies it as a bulk material, the corner diverter is triggered to deflect in the second direction, thereby pushing the bulk material without steel bars to the fifth material conveyor 9;

[0064] The metal detection component 7 does not identify the steel bars as plate-like materials, and the size detection component 6 identifies them as plate-like materials, triggering the corner diverter to deflect in the third direction, thereby pushing the plate-like materials without steel bars to the sixth material conveyor 11.

[0065] The present invention discloses a material processing system based on a construction site, which can sort materials containing steel bars and materials without steel bars at the construction site, and realize refined classification and processing of block materials without steel bars and plate materials without steel bars; it integrates size detection, metal detection and intelligent sorting technology to significantly improve the processing efficiency of construction waste, reduce equipment loss, and match special crushing equipment according to different material characteristics, and finally realize the triple goals of efficient recovery of steel bar resources, improvement of aggregate recycling rate and optimization of energy consumption of classified crushing; specifically, it can avoid the damage of steel bars to the corresponding crusher through metal sorting, adopt differentiated configuration of jaw crusher and impact crusher to improve crushing efficiency by more than 30%, and realize automatic classification and processing and transportation of construction waste in combination with a full-process lifting conveying system, so that the recycling rate of building materials such as concrete, bricks and gypsum boards reaches more than 90%, and at the same time, the oversized materials are pre-processed through the front punching table to ensure continuous and stable operation of the system.
