It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0029] Figure 1 This is a flowchart of a multi-source construction waste collaborative processing method provided by an embodiment of the present invention. This embodiment is applicable to the case of classifying and processing construction waste. The method can be executed by a multi-source construction waste collaborative processing device. The multi-source construction waste collaborative processing device can be implemented in the form of hardware and / or software. The multi-source construction waste collaborative processing device can be configured in any electronic device with network communication function. Figure 1 As shown, the method includes:

[0030] S110, determining target material properties of target construction waste.

[0031] The target material characteristics are used to characterize the types of target construction waste. Further, the target material characteristics include: construction and decoration waste, building demolition waste or engineering waste and construction concrete block waste.

[0032] Among them, construction waste refers to the abandoned soil, materials and other solid waste generated during the construction, reconstruction, expansion and demolition of various buildings, structures, pipe networks, etc. by construction units and construction units, as well as the abandoned soil, abandoned materials and other solid waste generated during the decoration and renovation of houses by residents. It mainly includes five categories: engineering slag, abandoned mud, engineering waste, demolition waste and decoration waste.

[0033] Specifically, the image information of the target construction waste is collected by a camera, and the image information of the target construction waste is recognized by an image recognition model to obtain the target material characteristics of the target construction waste.

[0034] Furthermore, the weight of the target construction waste placed in the loading port can be collected by a weight sensor, and the target material characteristics of the target construction waste can be determined according to the weight.

[0035] Furthermore, image recognition and weight sensors may also be combined to determine target material characteristics of target construction waste.

[0036] Exemplarily, the weight of the target construction waste placed at the loading port is first determined by a weight sensor to determine the first reference material property, and then the image information of the target construction waste is collected by a camera, and the image information of the target construction waste is recognized by an image recognition model to obtain the second reference material property, and the target material property is determined based on the first reference material property and the second reference material property. When the first reference material property and the second material property are inconsistent, an early warning is issued to prompt the management personnel to manually confirm.

[0037] S120. Matching a corresponding target waste treatment mode from candidate waste treatment modes according to the target material characteristics.

[0038] The candidate waste treatment modes include: a first treatment mode, a second treatment mode and a third treatment mode. The first treatment mode is used to first screen and then crush the construction and decoration waste, and to recover the recyclable resources in the construction and decoration waste. The second treatment mode is used to first crush and then screen the construction demolition waste or engineering waste, and to recover the recyclable resources in the construction demolition waste or engineering waste. The third treatment mode is used to recover metal resources in construction concrete block waste.

[0039] Specifically, if the target material characteristics characterize that the target construction waste is construction decoration waste, the first processing mode is matched; if the target material characteristics characterize that the target construction waste is construction demolition waste or engineering waste, the second processing mode is matched; if the target material characteristics characterize that the target construction waste is construction concrete block waste, the third processing mode is matched.

[0040] S130, processing the target construction waste according to the target waste processing mode.

[0041] Specifically, construction and decoration waste is processed by the first processing mode; construction demolition waste or engineering waste is processed by the second processing mode; and construction concrete blocks are processed by the third processing mode.

[0042] For example, Figure 2 As shown, when processing construction and decoration waste, the first processing mode is turned on, that is, the construction and decoration waste is loaded through the decoration waste loading port, and the system adopts the processing process route of "screening first and then crushing", and is equipped with three-stage screening, two-stage magnetic separation, two-stage air separation, one-stage intelligent robot sorting, one-stage manual sorting, and one-stage crushing equipment. It is turned on at the same time to ensure that all kinds of impurities in the decoration waste are fully removed.

[0043] Furthermore, when processing construction demolition waste or engineering waste, the second processing mode is turned on, that is, the construction demolition waste or engineering waste is loaded through the construction demolition waste or engineering waste or concrete block loading port, and the system adopts the "crushing first and then screening" processing process route, and the configured two-stage crushing, two-stage screening, three-stage magnetic separation, two-stage air separation, and one-stage manual sorting equipment are turned on at the same time to ensure that all kinds of impurities in the demolition waste / engineering waste are fully removed.

[0044] Furthermore, when processing construction concrete blocks, the third processing mode is turned on, that is, the construction concrete blocks are loaded from construction demolition waste or engineering waste or concrete block loading port. The impurity rate in the material itself is very low, mainly some metals hidden inside the concrete blocks. At this time, the system only needs to simultaneously turn on the secondary crushing, two-stage magnetic separation, and primary screening equipment to ensure that the metal resources are fully recycled and at the same time obtain the desired high-resource recycled aggregate products of different particle sizes.

[0045] The above steps are for the treatment of construction waste because construction waste has the characteristics of wide distribution, huge output, environmental pollution, complex composition, and difficulty in degradation, and there are also great differences in different regions. Compared with other domestic waste, construction waste is a kind of misplaced "resource" with huge value. It contains a large amount of recyclable aggregates, sand and gravel, wood, metal, paper and other resource materials. If it can be processed through technical means, the resource recycling of construction waste can be realized to the greatest extent. It will not only help to avoid the problems of urban construction waste accumulation and environmental pollution, but also recycle resources and form a closed loop of interests, bringing social, ecological and economic benefits, which is in line with the country's strategic route of sustainable development of circular economy.

[0046] The above steps, using different waste treatment modes to treat the target construction waste, are because at present, the recycling rate of construction waste in my country is about 10%, which is far lower than that of developed countries such as Europe, America, Japan and South Korea, which has reached more than 90%. The vast majority of construction waste has not been treated as a resource, and has not been recycled. Some are even dumped, scattered, and piled up at will, which not only occupies a large amount of land resources and affects the appearance of the city, but also easily causes problems such as secondary environmental pollution. In recent years, although local governments have also built many new construction waste disposal facilities, the commonly used construction waste treatment processes are either simple or complex, and can only adapt to a single type of construction waste disposal mode. If you want to dispose of multiple types of construction waste, you need to set up multiple processing production lines, resulting in a large overall project area, large civil engineering and equipment investment, and high energy consumption and operation and management costs. In some rapidly developing economic regions, the development of comprehensive utilization facilities for construction waste is relatively lagging due to the scarcity of land resources. In some economically underdeveloped regions, the development of comprehensive utilization facilities for construction waste is even more lagging due to large project investments and high operating costs. In addition, there have been many reports of violations in the utilization and disposal of construction waste in various places, such as illegal acceptance, direct dumping, or unknown whereabouts, which have seriously restricted the improvement of the level of resource utilization of construction waste in my country.

[0047] The above steps use different processing modes to treat the target construction waste. Only one production line can be used to efficiently process four different types of construction waste, with accurate classification, reduced sorting difficulty, improved sorting efficiency and resource utilization rate. Compared with the existing solutions, it can effectively reduce resource occupation and management costs.

[0048] Optionally, the first processing mode includes steps A1-A6:

[0049] Step A1: Screening construction and renovation waste by a primary screening machine to obtain a first material, and determining a first target material based on the first material.

[0050] The first material includes: the first screen material, the first screen material and the first screen material. The first screen material is the material left on the first screen of the first-level screening machine by the construction and decoration waste. For example, the first screen material is mainly large interfering objects such as large concrete blocks. For example, the particle size of the first screen material is greater than or equal to 300mm; the first screen material is the material left on the second screen of the first-level screening machine by the construction and decoration waste. For example, the particle size of the first screen material is 180-300mm; the first screen material is the material screened off the second screen of the first-level screening machine by the construction and decoration waste. For example, the particle size of the first screen material is less than or equal to 180mm.

[0051] The first-level screening machine is the first screening machine that construction and renovation waste passes through. The first-level screening machine is equipped with two layers of screens with gradually decreasing particle sizes. For example, the particle size of the first layer of the screen of the first-level screening machine is greater than or equal to 300mm; the particle size of the second layer of the screen is less than or equal to 180mm.

[0052] Specifically, the construction and decoration waste is loaded into the heavy-duty plate chain conveyor by a loader or an excavator, and the construction and decoration waste is evenly and stably conveyed into the primary screening machine by the heavy-duty plate chain conveyor. The primary screening machine can screen the construction and decoration waste into the first material, and the material that needs to be processed in the next step is the first target material. For example, if the material that needs to be processed in the next step is the first screened material, the first screened material is used as the first target material.

[0053] Step A2: if the first target material is the first oversize material, the first oversize material is subjected to a ground buffering and impurity removal treatment, and the first oversize material after impurity removal is processed by a third processing mode.

[0054] Specifically, if the first target material is the first screened material, the first screened material is directly placed on the ground for buffering, and after mechanical or manual impurity removal, the first screened material after impurity removal is processed through the third processing mode.

[0055] Step A3: If the first target material is the first screened material, the conveyor conveys it to the intelligent sorting device, sorts and removes impurities from the first screened material, and crushes the sorted and impurity-free first screened material through an impact crusher to obtain crushed material.

[0056] The crushed material is a mixture of crushed bricks, stones, concrete and the like.

[0057] Specifically, if the first target material is the first screened material, the first screened material transmitted by the conveyor is sorted by an intelligent sorting robot to pick out impurities such as wood, metal, and combustibles therein, and the remaining relatively pure first screened material is conveyed by the conveyor to the rear-end impact crusher for crushing to obtain crushed material.

[0058] Step A4: If the first target material is the first screened material, the first screened material is screened by a secondary screening machine to obtain a second material, and a second target material is determined based on the second material.

[0059] The second material includes: a second oversize material, a second midsize material and a second undersize material.

[0060] The second oversize is the material left on the first screen of the secondary screening machine by the first undersize. For example, the particle size of the second oversize is greater than or equal to 60 mm. The second undersize is the material left on the second screen of the secondary screening machine by the first undersize. For example, the particle size of the second undersize is 20-60 mm. The second undersize is the material screened off the second screen of the secondary screening machine by the first undersize. For example, the particle size of the second undersize is less than or equal to 20 mm.

[0061] Among them, the secondary screening machine is a screening machine for screening crushed materials or removing ferromagnetic metal building demolition waste or removing ferromagnetic metal engineering waste. The secondary screening machine is equipped with two layers of screens with gradually decreasing particle sizes, and the particle sizes of the screens are all smaller than the particle sizes of the primary screening machine screens. For example, the particle size of the first layer of the secondary screening machine is greater than or equal to 60mm; the particle size of the second layer of the screen is less than or equal to 20mm.

[0062] Specifically, if the first target material is the first undersize, the conveyor enters the secondary screening machine for screening to obtain the second material, and the material that needs to be processed in the next step is the second target material. For example, if the material that needs to be processed in the next step is the second oversize, the second oversize is used as the second target material.

[0063] Step A5: If the second target material is the second undersize material, the second undersize material is sent to the slag bin for temporary storage.

[0064] Specifically, if the second target material is the second undersize material, it indicates that the second undersize material is a slag mixture, which is directly conveyed by a conveyor to a corresponding slag bin for temporary storage.

[0065] Among them, the slag soil mixture can be used as landfill cover, road foundation backfill, and can also be used as a brick-making admixture for resource utilization.

[0066] Step A6: If the second target material is the second oversize material and / or the second midsize material, the second oversize material and / or the second midsize material are screened.

[0067] Specifically, if the second target material is the second oversize material and / or the second midsize material, the second oversize material and the second midsize material are subjected to magnetic metal and light material removal to obtain heavy material, and the heavy material is crushed to obtain crushed material.

[0068] Among them, light materials are mixed combustible debris.

[0069] Furthermore, after removing the light materials, the light materials are transported to the corresponding warehouse for temporary storage, and then transported to the incineration power plant for incineration and power generation or preparation of RDF fuel.

[0070] Furthermore, the magnetic metals are directly shipped out for sale.

[0071] Optionally, the second screen material and / or the second screen material are screened, comprising steps B1-B3:

[0072] Step B1: remove magnetic metals from the second oversize material and / or the second midsize material through a first magnetic separator to obtain a first material to be processed.

[0073] The first magnetic separator includes magnetic separator 1# and magnetic separator 2#, for example, Figure 3 As shown, magnetic separator 1# is used to remove magnetic metals from the second sieve material or the third sieve material; magnetic separator 2# is used to remove magnetic metals from the second sieve material or the third sieve material.

[0074] Specifically, the magnetic metal in the second oversize is removed by magnetic separator 1#; the magnetic metal in the second insize is removed by magnetic separator 2#, and the second oversize and / or the second insize after the magnetic metal is removed are used as the first material to be processed.

[0075] Furthermore, the magnetic metals are directly shipped out for sale.

[0076] Step B2: sending the first material to be processed into a target air separator to obtain heavy materials and light materials.

[0077] Among them, light materials are mixed combustible impurities, and heavy materials are materials composed of concrete, bricks, etc.

[0078] The target air separators include: air separator 1# and air separator 2#. Figure 3 As shown, air separator 1# is used to remove light materials in the second screen after the magnetic metal is removed or in the third screen after the magnetic metal is removed; air separator 2# is used to remove light materials in the second screen after the magnetic metal is removed or in the third screen after the magnetic metal is removed.

[0079] Specifically, after the magnetic metal is removed by the winnowing machine 1#, the light material in the second sieve is removed to obtain the heavy material; after the magnetic metal is removed by the winnowing machine 2#, the light material in the second sieve is removed to obtain the heavy material, and the removed light material is sent to the corresponding warehouse for storage.

[0080] Furthermore, the light materials can be subsequently transported to an incineration power plant for incineration to generate electricity or to prepare RDF fuel.

[0081] For example, Figure 3As shown, the material on the second sieve and the material in the second sieve are conveyed by a conveyor through magnetic separators 1# and 2#, respectively. After some ferromagnetic metals are removed, they enter air separators 1# and 2# respectively to separate the materials into heavy matter and light matter. The light matter is collected by the conveyor to the mixed combustible bin for temporary storage, and the heavy matter is collected by the conveyor to the artificial intelligence sorting room for further sorting and purification.

[0082] Furthermore, in the AI ​​sorting room, materials such as wood and paper are extracted from heavy materials through intelligent robots or manual means.

[0083] Step B3: crushing the heavy material by an impact crusher to obtain crushed material.

[0084] Specifically, the purified heavy material is conveyed from a conveyor to an impact crusher for crushing to obtain crushed materials.

[0085] Optionally, the second processing mode includes steps C1-C4:

[0086] Step C1, using a jaw crusher to roughly crush the building demolition waste or engineering waste, and using a second magnetic separator to remove ferromagnetic metals to obtain a first material to be screened.

[0087] The second magnetic separator is used to process building concrete block waste, building demolition waste or engineering waste. Figure 4 Magnetic separator 4#.

[0088] Specifically, the construction demolition waste or engineering waste is loaded into the vibrating feeder by a loader or an excavator, and the vibrating feeder sends the construction demolition waste or engineering waste to the jaw crusher evenly and continuously, and the construction demolition waste or engineering waste is subjected to primary coarse crushing. After the coarse crushing, the construction demolition waste or engineering waste is conveyed by a conveyor and passed through a magnetic separator 4# to remove part of the ferromagnetic metal to obtain the first material to be screened, and the first material to be screened is conveyed to the forward and reverse belt conveyor of the system, and the forward and reverse belt conveyor switches to the forward operation mechanism, and the first material to be screened is conveyed to the secondary screening machine.

[0089] Step C2: screening the first material to be screened using the secondary screening machine to obtain a third material, and determining a third target material based on the third material.

[0090] Among them, the third material includes: the third sieve material, the third sieve material and the third sieve material. Among them, the third sieve material is the material left on the first layer of the screen of the secondary screening machine by the first material to be screened. Exemplarily, the particle size of the third sieve material is greater than or equal to 60mm. The third sieve material is the material left on the second layer of the screen of the secondary screening machine by the first material to be screened. Exemplarily, the particle size of the third sieve material is 20-60mm. The third sieve material is the material screened off the second layer of the screen of the secondary screening machine by the first material to be screened. Exemplarily, the particle size of the third sieve material is less than or equal to 20mm.

[0091] Specifically, the first material to be screened is conveyed from a conveyor to a secondary screening machine for screening to obtain a third material, and the material currently to be processed in the next step is used as the second target material. For example, if the material to be processed in the next step is the second screened material, the second screened material is used as the second target material.

[0092] Step C3: If the third target material is the third undersize material, the third undersize material is sent to the slag bin for temporary storage.

[0093] Specifically, if the third target material is the third undersize material, it indicates that the third undersize material is a slag mixture, which is directly conveyed by a conveyor to a corresponding slag bin for temporary storage.

[0094] Step C4: if the third target material is the third oversize material and / or the third midsize material, the third oversize material and / or the third midsize material are screened.

[0095] Specifically, if the third target material is the third sieve oversize and / or the third sieve midsize, the third sieve oversize and the third sieve midsize are subjected to magnetic metal and light matter removal to obtain heavy matter, which is then crushed to obtain crushed material.

[0096] Optionally, the third sieve material and / or the third sieve material are subjected to sieving treatment, including steps D1-D3:

[0097] Step D1: remove magnetic metal from the third oversize material and / or the third midsize material through a first magnetic separator to obtain a second material to be processed.

[0098] Specifically, the magnetic metal in the third oversize is removed by magnetic separator 1#; the magnetic metal in the third insize is removed by magnetic separator 2#, and the third oversize and / or the third insize after the magnetic metal is removed are used as the second material to be processed.

[0099] Step D2: sending the second material to be processed into a target winnowing machine to obtain heavy materials and light materials.

[0100] Specifically, the light materials in the third sieve after the magnetic metal is removed by the winnowing machine 1# are used to obtain heavy materials; the light materials in the third sieve after the magnetic metal is removed by the winnowing machine 2# are used to obtain heavy materials, and the removed light materials are sent to the corresponding warehouse for storage.

[0101] For example, Figure 4 As shown, the material on the third screen and the material in the third screen are conveyed by a conveyor through magnetic separators 1# and 2#, respectively. After removing some ferromagnetic metals, they enter air separators 1# and 2# respectively to separate the materials into heavy materials and light materials. The light materials are collected by the conveyor to the mixed combustible bin for temporary storage, and the heavy materials are collected by the conveyor to the artificial intelligence sorting room for further sorting and purification.

[0102] Furthermore, in the AI ​​sorting room, materials such as wood and paper are extracted from heavy materials through intelligent robots or manual means.

[0103] Step D3: sort and purify the heavy materials, and crush them by an impact crusher to obtain crushed materials.

[0104] Specifically, the purified heavy material is conveyed from a conveyor to an impact crusher for crushing to obtain crushed materials.

[0105] Optionally, the third processing mode includes steps E1-E2:

[0106] Step E1: coarsely crush the construction concrete block waste by a jaw crusher, and remove the ferromagnetic metal by a second magnetic separator to obtain a material to be crushed.

[0107] The second magnetic separator is used to process building concrete block waste, building demolition waste or engineering waste. Figure 4 Magnetic separator 4#.

[0108] Specifically, the building concrete blocks are loaded into the vibrating feeder by a loader or an excavator, and the vibrating feeder sends the building concrete blocks to the jaw crusher evenly and continuously for primary coarse crushing. After the coarsely crushed building concrete blocks are conveyed by a conveyor and passed through a magnetic separator 4# to remove part of the ferromagnetic metal, the material to be crushed is obtained.

[0109] Step E2: crushing the material to be crushed by an impact crusher to obtain crushed material.

[0110] Specifically, the material to be crushed is conveyed to the forward and reverse belt conveyor of the system, and the forward and reverse belt conveyor is switched to the reverse operation mechanism, and the material to be crushed is directly conveyed to the impact crusher for secondary fine crushing to obtain crushed materials.

[0111] Optionally, after crushing the material by an impact crusher, the steps F1-F3 are included:

[0112] Step F1: removing ferromagnetic metals from the crushed materials by a third magnetic separator, and screening the crushed materials from which the ferromagnetic metals have been removed by a three-stage screening machine to obtain recycled aggregates.

[0113] Among them, the three-stage screening machine is used to screen the crushed materials to remove ferromagnetic metals. The three-stage screening machine is equipped with three layers of screens with gradually decreasing particle sizes, and the particle sizes of the screens are set according to the particle size requirements of the recycled aggregate. For example, the particle size of the first layer of the three-stage screening machine is 31.5mm; the particle size of the second layer of the screen is 10mm; and the particle size of the third layer of the screen is 5mm.

[0114] Among them, recycled aggregates can be used as raw materials for building materials such as brick making, concrete preparation, dry-mix mortar, recycled water-stabilized materials, or directly used as roadbed backfill for resource utilization.

[0115] The third magnetic separator is arranged after the first magnetic separator to remove ferromagnetic metals from the crushed material. Figure 5 As shown, the third magnetic separator is magnetic separator 3#.

[0116] Specifically, after part of the ferromagnetic metal in the crushed material is removed by the third magnetic separator, the material is transported to the third-stage screening machine for screening. The third-stage screening machine can screen the material into three different particle sizes of recycled aggregate: fine, medium and coarse.

[0117] Step F2: If the particle size of the recycled aggregate is within a preset range, the recycled aggregate is temporarily stored in an aggregate bin according to the corresponding particle size.

[0118] The preset range is flexibly adjusted according to the specific needs of the project. For example, the preset range can be 0-31.5mm; the fine particle size of recycled aggregate is 0-5mm; the medium particle size of recycled aggregate is 5-10mm; and the coarse particle size of recycled aggregate is 10-31.5mm.

[0119] Specifically, if the particle size of the recycled aggregate meets the preset range, the fine-sized recycled aggregate is sent to the fine-sized aggregate bin; the medium-sized recycled aggregate is sent to the medium-sized aggregate bin; and the coarse-sized recycled aggregate is sent to the coarse-sized aggregate bin.

[0120] Step F3: If the particle size of the recycled aggregate is not within the preset range, it is subjected to impurity removal treatment by an aggregate purifier and then crushed and screened.

[0121] Specifically, if the particle size of the recycled aggregate is greater than 31.5mm, it does not meet the production requirements, so it needs to be crushed and screened. Before crushing and screening, it is necessary to determine whether the purity of the recycled aggregate meets the requirements. If it does, it is directly crushed by an impact crusher and then screened by a three-stage screening machine. If it does not meet the requirements, it needs to be removed by an aggregate purifier, crushed by an impact crusher, and then screened by a three-stage screening machine. Determine whether the particle size of the screened recycled aggregate meets the preset range. If it does, store the recycled aggregate in the aggregate bin according to the corresponding particle size for temporary storage; if it does not meet the requirements, crushing and screening are performed again.

[0122] For example, Figure 3As shown in the figure, it is the flow chart of the first processing mode, which adopts the processing route of "screening first and then crushing", and is equipped with three-stage screening, two-stage magnetic separation, two-stage air separation, one-stage intelligent robot sorting, one-stage manual sorting, and one-stage crushing equipment. The specific steps are as follows: the received construction and decoration waste is loaded into the heavy-duty plate chain conveyor by a loader or excavator, and the material is evenly and stably conveyed to the first-stage screening machine by the conveyor. The first-stage screening machine can screen the material into three materials with different particle sizes, among which the screened materials are mainly large pieces of concrete blocks and other large interferences, which are directly cached on the ground. After mechanical and manual impurity removal, the remaining materials are treated as building concrete blocks. The first-stage screening machine screens the first screened material, and the first screened material is transferred to the intelligent sorting robot through the conveyor. The intelligent sorting robot sorts the first screened material, picks out impurities such as wood, metal, and combustibles, and reduces labor costs. The remaining relatively pure materials are conveyed by the conveyor into the back-end impact crusher for crushing. The undersize material screened by the primary screening machine is conveyed to the secondary screening machine by the conveyor, and is again screened by the secondary screening machine into three materials of different particle sizes. The undersize material screened by the secondary screening machine is a mixture of slag and soil, which is directly conveyed by the conveyor to the corresponding slag bin for temporary storage. The oversize material and the undersize material screened by the secondary screening machine are conveyed by the conveyor through magnetic separators 1# and 2#, respectively, and after removing some ferromagnetic metals, they enter air separators 1# and 2# respectively to sort the materials into heavy materials and light materials. The light materials are mixed combustible impurities and are collected by the conveyor to the mixed combustible bin for temporary storage, while the heavy materials are collected by the conveyor to the artificial intelligence sorting room for further sorting and purification. The purified heavy materials are conveyed to the impact crusher for crushing by the conveyor, and the crushed materials are conveyed by the conveyor through magnetic separator 3#, and after removing some ferromagnetic metals, they are conveyed to the third-stage screening machine for material screening. The third-stage screening machine can screen the materials into three different particle sizes of recycled aggregates: fine, medium and coarse. Fine and medium-sized recycled aggregates are directly conveyed by conveyors to aggregate silos of corresponding sizes for temporary storage. Coarse-sized recycled aggregates are conveyed by conveyors to aggregate purifier 1# for further impurity removal and then conveyed by conveyors to aggregate silos of corresponding sizes for temporary storage. The top layer of materials from the three-stage screening machine are conveyed by conveyors to aggregate purifier 2# for impurity removal and then returned to the impact crusher for further crushing. The crushing and screening are cyclically carried out to control the particle size of the system's recycled aggregate products.

[0123] For example, Figure 4As shown in the flowchart of the second processing mode, the processing route of "crushing first and then screening" is adopted, and the two-stage crushing, two-stage screening, three-stage magnetic separation, two-stage air separation, and one-stage manual sorting equipment are configured to start and operate at the same time. The specific steps are as follows: the received building demolition waste or engineering waste is loaded into the vibrating feeder by a loader or excavator. The vibrating feeder evenly and continuously sends the material to the jaw crusher for primary coarse crushing. The coarsely crushed material is conveyed by the conveyor to the system's forward and reverse belt conveyor after removing some ferromagnetic metals from the magnetic separator 4#. The forward and reverse belt conveyor switches to the forward running mechanism, and the material is conveyed to the secondary screening machine. The secondary screening machine screens the coarsely crushed material into three materials with different particle sizes, among which the screened material is a slag mixture, which is directly conveyed by the conveyor to the corresponding slag bin for temporary storage. The oversize and midsize materials screened by the secondary screening machine are conveyed by a conveyor through magnetic separators 1# and 2#, respectively. After removing some ferromagnetic metals, they enter air separators 1# and 2# respectively to separate the materials into heavy and light materials. The light materials are mixed combustible impurities and are collected by the conveyor to the mixed combustible bin for temporary storage, while the heavy materials are collected by the conveyor to the artificial intelligence sorting room for further sorting and purification. The purified heavy materials are conveyed by the conveyor to the impact crusher for crushing. The crushed materials are conveyed by the conveyor through magnetic separator 3#, and after removing some ferromagnetic metals, they are conveyed to the third-stage screening machine for screening. The third-stage screening machine can screen the materials into three different particle sizes of recycled aggregates: fine, medium and coarse. Fine and medium-sized recycled aggregates are directly conveyed by conveyors to aggregate silos of corresponding sizes for temporary storage. Coarse-sized recycled aggregates are conveyed by conveyors to aggregate purifier 1# for further impurity removal and then conveyed by conveyors to aggregate silos of corresponding sizes for temporary storage. The top layer of materials from the three-stage screening machine are conveyed by conveyors to aggregate purifier 2# for impurity removal and then returned to the impact crusher for further crushing. The crushing and screening are cyclically carried out to control the particle size of the system's recycled aggregate products.

[0124] For example, Figure 5As shown, when processing building concrete blocks, the building concrete block processing mode is turned on. At this time, the impurity rate of the material itself is very low, mainly some metal resources hidden inside the concrete blocks. The system only needs to start the configured secondary crushing, two-stage magnetic separation, and primary screening equipment at the same time. The specific steps are as follows: The building concrete blocks received by the project are loaded into the vibrating feeder by a loader or excavator. The vibrating feeder evenly and continuously sends the materials to the jaw crusher for primary coarse crushing. The coarsely crushed materials are conveyed by the conveyor through the magnetic separator 4# to remove some ferromagnetic metals and then conveyed to the forward and reverse belt conveyor of the system. The forward and reverse belt conveyor switches to the reverse operation mechanism, and the materials are directly conveyed by the conveyor to the impact crusher for secondary fine crushing. The finely crushed materials are conveyed by the conveyor through the magnetic separator 3#, and after removing some ferromagnetic metals, they are conveyed to the three-stage screening machine for material screening. The three-stage screening machine can screen the materials into three different particle sizes of recycled concrete aggregates: fine, medium, and coarse. Fine, medium and coarse particle size recycled concrete aggregates have high purity and do not need to be purified. They are directly transported by conveyor to the aggregate bin of corresponding particle size for temporary storage. The top layer of material of the three-stage screening machine is directly returned to the impact crusher through the conveyor for re-crushing. The cycle of crushing and screening controls the particle size of the system recycled aggregate products.

[0125] The above steps adopt different processing modes according to the characteristics of different types of construction waste materials. The different types of construction waste processing modes are activated through the setting of different feeding ports, forward and reverse belt conveyor bypass paths, reasonable layout of equipment and intelligent switching of the electronic control system. The system process route is smoother, the equipment is highly integrated and modularly designed, and the equipment functions are maximized.

[0126] The technical solution of this embodiment determines the target material characteristics of the target construction waste, providing a selection basis for the subsequent matching treatment mode; according to the target material characteristics, the corresponding target waste treatment mode is matched from the candidate waste treatment mode, which can match different waste treatment modes according to different target construction wastes, thereby improving the flexibility of waste treatment; the target construction waste is treated according to the target waste treatment mode, which can improve the recovery rate of resources in the waste. This method processes the target construction waste through different waste treatment modes, which can realize flexible switching of treatment modes, has high adaptability, and also avoids the problem of resource waste caused by the existing treatment method of treating all construction waste through a single treatment method.
