Description

Technical Field

[0001] The utility model relates to the field of energy-saving construction waste recycling, in particular to a construction waste recycling device. Background Art

[0002] After the demolition of energy-saving buildings, a large amount of construction waste such as concrete blocks, slag, waste bricks and stones will be generated. In order to improve the utilization rate of resources, these wastes can be crushed or pulverized and can be used for laying foundations or as aggregates for new concrete.

[0003] At present, a Chinese patent discloses an energy-saving construction waste recycling device, and its announcement number is CN220559342U. In the technical solution of this application, the device uses an extrusion and crushing method to crush the construction waste, and uses a separation mechanism to realize the classification of metal materials and non-metallic waste such as steel bar segments, nails and angle irons, so that various wastes can be classified and reasonably reused, reducing the difficulty of manual sorting work and being more energy-saving and environmentally friendly.

[0004] In combination with the above-disclosed technical solution, when adsorbing metal in crushed waste, after the electromagnet adsorbs the metal for a period of time, it is necessary to move the electromagnet to the outside of the conveyor frame, and then cut off the power to the electromagnet to make the adsorbed metal fall. This causes a period of working vacuum during the process of the electromagnet adsorbing the metal, which reduces the working efficiency of the device and makes it impossible to process the dust of construction waste. Therefore, we propose a construction waste recycling device to solve this problem. Utility Model Content

[0036] Pulleys are arranged on both sides of the first transmission belt 9 , the second transmission belt 10 and the third transmission belt 11 , and the pulleys are fixedly connected to the corresponding gear shafts or motor shafts.

[0037] The implementation principle of a construction waste recycling device in the embodiment of the present application is as follows: after turning on the first motor 8, the second motor 7, the ventilating fan and the water pump, pour the construction waste into the feeding funnel 4, the first motor 8 drives the material distribution shaft 14 to rotate, and the rotation of the material distribution shaft 14 drives the baffle to rotate, and the rotation of the baffle causes the construction waste to fall into the crushing box 1 at a uniform speed, and the first motor 8 drives the second transmission belt 10 to rotate, so that the first gear 12 on the right side rotates, and the first gear 10 on the right side drives the first transmission belt 9 to rotate, thereby driving the second gear 13 on the right side to rotate, and the second gear 13 on the left side is driven by the rotation of the second gear 13 on the right side. The third transmission belt 11 is driven by the rotation of the second gear 13 on the left side, thereby driving the first gear 10 on the left side to rotate, and the two first gears 10 and the two second gears 13 are driven by the rotation of the two first crushing rollers 15 and the two second crushing rollers 16 to rotate, so that large blocks of construction waste are initially crushed. After the first crushing and the second fine crushing, the crushed construction waste falls onto the surface of the conveyor belt 6, and the fifth rotating belt 6 is driven by the rotation of the second motor 7. The crushed construction waste moves downward through the rotation of the conveyor belt 6. When the construction waste moves to the bottom of the magnet 19, the magnet 19 adsorbs the metal in the construction waste to the surface of the metal conveyor belt 18. The second gear 13 on the left side rotates to drive the bevel gear set 17 to rotate, thereby driving the transmission shaft at one end of the fourth rotating belt 18 to rotate. The metal conveyor belt 18 is driven as a whole through the rotation of the transmission shaft at one end of the fourth rotating belt 18. The metal is driven to move through the overall transmission of the metal conveyor belt 18. Since vertical plates are arranged at equal intervals on the surface of the metal conveyor belt 18, the metal conveyor belt 18 can drive the metal adsorbed by the magnet 19 to move. When the metal moves to the top of the metal collection box 5, the metal on the surface of the metal conveyor belt 18 falls into the metal collection box 5 due to the loss of the magnetic force range of the magnet 19.

[0038] Through the operation of the ducting fan, the three dust suction ports suck dust from all directions into the dust collecting box 22. Since a large-particle filter is installed at the connection between the first dust suction port and the crushing box 1, large particles of debris will not fall into the dust collecting box 22. The water in the water tank 20 is sucked by the water pump and sprayed out by the nozzle 21 to reduce the dust in the dust collecting box 22, and the sewage is discharged through the sewage pipe. Since a partition is provided in the middle of the inner side of the dust collecting box 22 and a filter is provided on the surface of the partition, the dust inside the dust collecting box 22 will not be sucked into the ducting fan.

[0039] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
