[0010] A separation method of a construction waste separation and recovery device, comprising the following steps:

[0011] Step 1: introduce an appropriate amount of water source into the cleaning box through the trapezoidal feed hopper, then start the first motor, drive the water pump and the power storage module, and introduce the concrete blocks to be separated and recycled into the trapezoidal feed hopper in batches. When the concrete blocks to be separated and recycled are introduced into the trapezoidal feed hopper, they will slide along the inclined surface of the trapezoidal feed hopper. When the concrete blocks to be separated and recycled contact with the cross rotating frame, they will push it to rotate, thereby driving the first rotating rod to rotate, and then driving the second synchronous wheel to rotate, and further driving the first synchronous wheel to rotate through the transmission synchronous belt, thereby driving the limit inner ratchet to rotate, and then driving the driven ring to rotate through the limit ratchet, and further driving the second rotating rod to rotate, thereby driving the U-shaped stirring plate to rotate through the installation ring;

[0012] Step 2: When the concrete blocks to be separated and recycled are separated from the cross rotating frame, the cross rotating frame will stop rotating. At this time, the corresponding concrete blocks to be separated and recycled will fall between the first crushing roller and the second crushing roller. At the same time, the first motor will drive the second sprocket and the second gear to rotate, so that the first sprocket can be driven to rotate through the transmission chain, and then the corresponding crushing rotating rod can be driven to rotate through the first side rod, and the first crushing roller can be further driven to rotate. The second gear will drive the first gear to reverse, so that the corresponding crushing rotating rod can be driven to reverse through the second side rod, and then the second crushing roller can be driven to reverse synchronously, so that the corresponding fallen concrete blocks to be separated and recycled can be quickly and efficiently crushed, and the crushed concrete blocks will fall on the arc-shaped magnetic suction plate. At this time, the power storage module can energize the electromagnetic rod and make it generate strong magnetism. Then, the magnetism will be guided to the arc-shaped magnetic suction plate through the magnetic conductive frame, so that the steel bars in the crushed concrete blocks can be adsorbed, and then the crushed concrete blocks without steel bars will be introduced into the cleaning box through the guide vertical pipe;

[0013] Step three, during this period, the driving water pump can guide the water source in the cleaning box into the two liquid outlet conduits through the liquid inlet conduit, and then the water source will be guided into the corresponding liquid guide inner groove through the second liquid guide ring, and then the water source will flow in the corresponding liquid guide inner groove, and during the flow period, the heat generated during the crushing of the first crushing roller and the second crushing roller can be fully absorbed, and then the heat-absorbing water source will be guided into the corresponding first liquid guide ring and guided into the corresponding return conduit and spray conduit by the first liquid guide ring. At this time, part of the heat-absorbing water source will flow back into the cleaning box, and the other part of the heat-absorbing water source will be guided into the spray spray plate and evenly sprayed onto the concrete blocks to be separated and recycled by the spray spray plate;

[0014] Step 4: when a proper amount of crushed concrete blocks are introduced into the cleaning box, the introduction operation of the concrete blocks to be separated and recycled is stopped, and then the first motor is turned off, the water pump and the storage module are driven, and the second motor is started. At this time, the second motor will drive the second rotating rod to rotate again, so that the U-shaped stirring plate can be driven to rotate again through the installation ring, and then the heated water source and the crushed concrete blocks can be stirred, so that the crushed concrete blocks can be effectively cleaned, and the second rotating rod will synchronously drive the driven ring to rotate, and then drive the limit ratchet to rotate synchronously, and further can compress the V-shaped elastic sheet in turn and make the limit ratchet slide along the teeth of the limit inner ratchet;

[0015] Step 5. After the corresponding crushed concrete blocks are cleaned, the second motor is turned off, and the cleaned concrete blocks are taken out for subsequent grading and other treatments to make recycled concrete. At the same time, the electric telescopic rod is started to drive the connecting side ears to move downward, and then the magnetic frame and the arc-shaped magnetic plate are driven downward, and the separated steel bars are further driven downward. Then the battery module is turned off and the separated steel bars are removed. After that, the arc-shaped magnetic plate is reset and the subsequent crushing and cleaning operations of the concrete blocks to be separated and recycled are carried out according to the above steps.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Through the coordinated use of the crushing mechanism and the separation mechanism, the first crushing roller and the second crushing roller can be driven to reverse synchronously, so that the fallen concrete blocks to be separated and recycled can be crushed quickly and efficiently, and the crushed concrete blocks will fall on the arc-shaped magnetic suction plate. At this time, the storage module can energize the electromagnetic rod and make it generate strong magnetism. Then the magnetism will be guided to the arc-shaped magnetic suction plate through the magnetic conductive frame, and then the steel bars in the crushed concrete blocks can be adsorbed, thereby realizing the convenient separation and recovery of the crushed concrete blocks and steel bars;

[0018] 2. Through the use of the cleaning mechanism, the cross rotating frame can be driven to rotate when the concrete blocks to be separated and recycled are fed, so that the driven ring can be driven to rotate through the limit ratchet, and then the second rotating rod can be driven to rotate, so that the U-shaped stirring plate can be driven to rotate through the installation ring, and then the water source and the crushed concrete blocks in the cleaning box can be initially stirred, thereby effectively utilizing the force generated when the concrete blocks to be separated and recycled are fed, and when a proper amount of crushed concrete blocks are introduced into the cleaning box, the U-shaped stirring plate can be driven to rotate again, and then the water source and the crushed concrete blocks can be stirred, so that the crushed concrete blocks can be effectively cleaned, and when the second motor is driven, the V-shaped elastic sheet can be compressed in turn and the limit ratchet can slide along the teeth of the ratchet wheel inside the limit, so that there is no need to drive the cross rotating frame etc. to rotate, thereby reducing the load of the second motor and further reducing energy consumption;

[0019] 3. Through the setting and use of the auxiliary mechanism, the water source in the cleaning box can be introduced into the two liquid outlet conduits through the liquid inlet conduit, and then the water source will be introduced into the corresponding liquid guide inner groove through the second liquid guide ring, and then the water source will flow in the corresponding liquid guide inner groove, and during the flow, the heat generated during the crushing of the first crushing roller and the second crushing roller can be fully absorbed, and then the heat-absorbing water source will be introduced into the corresponding first liquid guide ring and introduced into the corresponding return conduit and spray conduit by the first liquid guide ring. At this time, part of the heat-absorbing water source will flow back into the cleaning box, and the other part of the heat-absorbing water source will be introduced into the spray nozzle plate and evenly sprayed onto the concrete blocks to be separated and recycled by the spray nozzle plate, so that the concrete blocks to be separated and recycled can be sprayed and preheated, thereby effectively reducing the adhesion between the soil and the concrete blocks, especially when working in cold weather. The effect is more obvious, and the use of the heat-absorbing water source to clean the crushed concrete blocks can effectively improve the cleaning effect of the concrete blocks.

[0041] Step 1: introduce a proper amount of water into the cleaning box 41 through the trapezoidal feed hopper 23, then start the first motor 211, drive the water pump 51 and the power storage module 35, and introduce the concrete blocks to be separated and recycled into the trapezoidal feed hopper 23 in batches. When the concrete blocks to be separated and recycled are introduced into the trapezoidal feed hopper 23, they will slide along the inclined surface of the trapezoidal feed hopper 23. When the concrete blocks to be separated and recycled contact with the cross rotating frame 415, it will push it to rotate, thereby driving the first rotating rod 42 to rotate, and then driving the second synchronous wheel 413 to rotate, and further driving the first synchronous wheel 411 to rotate through the transmission synchronous belt 414, thereby driving the limit inner ratchet 412 to rotate, and then driving the driven ring 47 to rotate through the limit ratchet 49, and further driving the second rotating rod 44 to rotate, so that the U-shaped stirring plate 46 can be driven to rotate through the mounting ring 45;

[0042] Step 2: When the concrete blocks to be separated and recycled are separated from the cross rotating frame 415, the cross rotating frame 415 will stop rotating. At this time, the corresponding concrete blocks to be separated and recycled will fall between the first crushing roller 25 and the second crushing roller 26. At the same time, the first motor 211 will drive the second sprocket 212 and the second gear 213 to rotate, thereby driving the first sprocket 28 to rotate through the transmission chain 214, and then driving the corresponding crushing rotating rod 24 to rotate through the first side rod 27, further driving the first crushing roller 25 to rotate, and the second gear 213 will drive the first gear 210 to reverse, thereby The corresponding crushing rotating rod 24 can be driven to reverse through the second side rod 29, and then the second crushing roller 26 can be driven to reverse synchronously, so that the corresponding fallen concrete blocks to be separated and recycled can be crushed quickly and efficiently, and the crushed concrete blocks will fall on the arc-shaped magnetic attraction plate 37. At this time, the storage module 35 can energize the electromagnetic rod 36 and make it generate strong magnetism, and then the magnetism will be guided to the arc-shaped magnetic attraction plate 37 through the magnetic frame 34, so that the steel bars in the crushed concrete blocks can be adsorbed, and then the crushed concrete blocks without the steel bars will be introduced into the cleaning box 41 through the guide vertical pipe 22;

[0043] Step three, during this period, the driving water pump 51 can guide the water source in the cleaning box 41 into the two liquid outlet conduits 54 through the liquid inlet conduit 53, and then the water source will be introduced into the corresponding liquid guide inner groove 216 through the second liquid guide ring 56, and then the water source will flow in the corresponding liquid guide inner groove 216, and during the flow period, the heat generated during the crushing of the first crushing roller 25 and the second crushing roller 26 can be fully absorbed, and then the heat-absorbing water source will be introduced into the corresponding first liquid guide ring 52 and introduced into the corresponding return conduit 57 and the spray conduit 58 by the first liquid guide ring 52. At this time, part of the heat-absorbing water source will flow back to the cleaning box 41, and the other part of the heat-absorbing water source will be introduced into the spray spray plate 59 and sprayed evenly onto the concrete blocks to be separated and recycled by the spray spray plate 59;

[0044] Step 4, when a proper amount of crushed concrete blocks are introduced into the cleaning box 41, the introduction of the concrete blocks to be separated and recycled is stopped, and then the first motor 211 is turned off, the water pump 51 and the power storage module 35 are driven, and the second motor 43 is started. At this time, the second motor 43 will drive the second rotating rod 44 to rotate again, so that the U-shaped stirring plate 46 can be driven to rotate again through the installation ring 45, so as to stir the heated water source and the crushed concrete blocks, so as to effectively clean the crushed concrete blocks, and the second rotating rod 44 will synchronously drive the driven ring 47 to rotate, and then drive the limit ratchet 49 to rotate synchronously, and further can compress the V-shaped elastic sheet 410 in sequence and make the limit ratchet 49 slide along the teeth of the limit inner ratchet 412;

[0045] Step five, when the corresponding crushed concrete blocks are cleaned, the second motor 43 is turned off, and the cleaned concrete blocks are then taken out for subsequent grading and other treatments to make recycled concrete. At the same time, the electric telescopic rod 32 is started, so that the connecting side ears 33 can be driven downward, and then the magnetic frame 34 and the arc-shaped magnetic plate 37 can be driven downward, and the separated steel bars can be further driven downward. Then the power storage module 35 is turned off and the separated steel bars are removed, and then the arc-shaped magnetic plate 37 is reset and the subsequent crushing and cleaning operations of the concrete blocks to be separated and recycled are carried out according to the above steps.
