Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building waste recycling and reprocessing, especially to a building waste recycled aggregate intelligent pipe control device. BACKGROUND

[0002] The preparation of building waste recycled aggregate is an important way to realize the resource utilization of building waste. With the enhancement of environmental awareness and the progress of technology, the traditional recycled aggregate preparation process cannot meet the requirements of high efficiency, intelligence and environmental protection. Therefore, developing a building waste recycled aggregate preparation device that can realize automatic and intelligent management has become an inevitable trend in the industry.

[0003] The purpose of fine screening is to classify building waste according to particle size, ensuring that the particle size distribution of recycled aggregate meets the standard requirements. At the same time, the screening process can also remove small dust, soil and other impurities, improving the purity of recycled aggregate. The purpose of iron removal is to separate ferromagnetic materials (such as steel bars, nails, and iron sheets) from building waste, preventing these materials from entering subsequent equipment and causing equipment damage or affecting product quality. At the same time, the separated ferromagnetic materials can be recycled and reused, reducing resource waste.

[0004] Although some progress has been made in fine screening and iron removal technology in building waste recycling and processing, there are still some technical and process defects in actual application. These defects not only affect the quality of recycled aggregate, but also may cause equipment failure, environmental pollution and other problems. The main defects of fine screening and iron removal technology in building waste recycling and processing are insufficient screening precision, incomplete separation of lightweight impurities, incomplete separation of ferromagnetic materials, poor adaptability of iron removal equipment, lack of intelligent management system, low automation level, low resource utilization rate and serious construction pollution.

[0024] As shown in Figure 2As shown, the suspension type electromagnetic iron remover 2 is connected with the eccentric vibrating screen powder machine 1 through the frame rod 41, and the side plate 40 and the frame rod 41 are welded to form a fixed frame 25. The electromagnetic source 28 is fixed on the side plate 40 by high-strength bolts 27.

[0026] As shown in the drawings, Figure 4 The operation technical process of the building waste recycled aggregate intelligent pipe control device is as follows:

[0027] Step one, particle feeding: the broken waste is put into the eccentric vibrating screen powder machine.

[0028] Step two, weight adjustment and vibration amplitude: the weight of the waste particles put in is weighed by the weighing plate in the eccentric vibrating screen powder machine, and the vibration frequency and amplitude of the eccentric vibrating screen powder machine are intelligently adjusted. Start the eccentric vibrating screen powder machine to screen the particles. The recycled aggregate at each level is produced from the corresponding discharge port.

[0029] Step three, iron remover: open the suspension type electromagnetic iron remover to extract metal from the waste particles in the first stage screening bin. Through the video intelligent recognition of the block and the weighing result of the particles, the metal content in the waste is preliminarily judged, and the magnetic size of the electromagnetic source in the suspension type electromagnetic iron remover is adjusted. Open the permanent magnet roller iron remover to extract metal from the waste particles in the second stage screening bin. The extracted metal impurities are classified and recycled as needed.

[0030] Step four, recycled aggregate classification collection: the recycled aggregate is classified into oversized particles, 10mm-15mm grade aggregate, 5mm-10mm grade aggregate and fine waste after iron removal and screening. The oversized particles are put into the crusher for re-crushing, the fine waste is discarded or treated separately, and the finished 10mm-15mm recycled aggregate and 5mm-10mm recycled aggregate are packaged and stored in a flat, solid and dry place.

[0031] The crushed particles are put into the eccentric vibrating screen powder machine 1 and start to be screened. The particles with a particle size less than 10mm in the first screening bin 15 pass through the 10mm sieve plate 43 and fall into the second screening bin 13. The particles with a particle size greater than 10mm are concentrated outward under the action of centrifugal force. The particles with a particle size less than 15mm pass through the first discharge port 14. The particles with a particle size greater than 15mm are left in the first screening bin 15. The particles entering the second screening bin 13 continue to be screened. The particles with a particle size less than 5mm fall from the 5mm sieve plate 44 and are discharged through the discharge port 11. The particles with a particle size greater than 5mm diffuse to the edge of the machine under the action of centrifugal force and are discharged through the second discharge port 20. The weight of the waste can be determined by the weighing plate 22 during screening, and the position of the eccentric block 9 and the power output of the screen powder machine motor 8 can be adjusted to control the frequency and amplitude of the vibration. The rotation of the sieve plate 19 can improve the efficiency of waste screening.

[0032] The power is turned on to generate an electromagnetic field by the electromagnetic source 28. The metal in the waste is attracted to the transmission track 29 by the magnetic force. The transmission track 29 rotates and moves the metal to the edge of the machine under the action of the stirring bar 42. The magnetic plate 31 can isolate the magnetic force at the edge of the machine. The metal falls under the action of gravity and falls out of the first iron discharge port 24.

[0033] The content of iron in the waste can be preliminarily determined by intelligent video recognition and the weighing plate 22 during operation, and the current can be adjusted to control the size of the magnetic field, thereby reducing energy consumption.

[0034] The rotor 38 drives the rotating drum 33 to rotate. The permanent magnet source 36 made of high-performance neodymium iron boron emits strong magnetic force to attract the metal to the rotating drum 33. The screening rib 34 rotates with the metal. When passing through the demagnetizing plate 35, the magnetic force is isolated, and the metal falls under the action of gravity and is discharged from the second iron discharge port 21.

[0035] The present application adopts a multi-stage precise screening technology for waste particles, which finely screens the waste through different levels of sieve plates and screening bins. The quality of the recycled material can be improved, and the resource utilization rate can be improved.

[0036] The application adopts high-efficiency dynamic self-unloading magnetic separation iron removal technology, uses double iron removal of a suspended electromagnetic iron remover and a permanent magnetic drum iron remover, and does not need a construction operator to manually clean metal slag, so that dynamic high-efficiency iron removal is realized.

[0037] The application adopts whole-process intelligent management and control coordination technology, adjusts vibration frequency and amplitude of vibration screening through weighing of waste and intelligent video identification, can improve production efficiency, avoids energy consumption waste, and improves economic benefits of engineering.

[0038] The application adopts dust-free green construction technology, reduces dust in a construction site through a blowing machine and a water mist sprayer, can protect an environment of an operation space, and guarantees physical health of an operator.

[0039] The utility model is not limited to the above-mentioned best implementation, and anyone can derive other various forms of products under the enlightenment of the utility model, but no matter any change in shape or structure, any technical scheme with the same or similar to the application falls within the protection scope of the utility model.
