Problems solved by technology

[0002] Construction waste refers to the waste generated during the process of building new construction, reconstruction, expansion, and demolition, mainly including reinforced concrete, cement mortar, masonry, bamboo, wood, steel and decorative glass that can be used as the main structure of the building. Ceramics, asphalt, plastic, gypsum, etc.; the largest amount of construction waste is the construction waste generated when the main structure of the building is dismantled, such as reinforced concrete blocks, masonry blocks, plain concrete blocks, mortar blocks, etc. These construction wastes can be further processed Crushing and screening, used as recycled aggregate or recycled decorative bricks, but it contains steel bars, metal embedded parts and other materials that are difficult to break and have higher recycling value
[0003] In conventional construction waste recycling, crushers are often used to break reinforced concrete blocks, and then the metal materials are manually screened out. However, this process not only consumes a lot of manpower, but also has low screening efficiency.

Embodiment 1

[0025] see Figure 1-5 , a crushing and recycling device for construction waste, comprising a crushing box 1 and a recycling box 2, the top and bottom of the crushing box 1 are respectively provided with a feed port 3 and a discharge port 4, and the crushing box 1 is arranged from top to bottom. A plurality of pulverizing mechanisms 5 are arranged, and the discharge port 4 is connected with the recovery box 2, and the lower end of the discharge port 4 in the recovery box 2 is provided with a conveying device 6, and the conveying device 6 includes a driving roller 7, a driven roller 8 and a conveyor belt 9, the conveyor belt 9 is supported between the driving roller 7 and the driven roller 8, and the conveyor belt 9 is provided with a screen hole, and the driving roller 7 and the driven roller 8 are all rotated with the recovery box 2 connected, and the driving roller 7 is provided with three driving teeth 10, and the three driving teeth 10 are distributed in an annular array o...

Embodiment 2

[0033] This embodiment has been improved on the basis of Embodiment 1, specifically:

[0034] The two side walls of the top of the crushing box 1 are symmetrically fixed with a rotating shaft 25, and a door 26 is hinged on the rotating shaft 25, and a telescopic rod 27 is arranged between the bottom surface of the door 26 and the side wall of the crushing box 1. , the telescopic rod 27 is covered with a third spring 28, by setting the door 26, when the construction waste is imported, under the gravity of the construction waste, the doors 26 on both sides are opened, so that the construction waste is introduced into the crushing box 1 Inside, after the construction waste enters the crushing box 1, under the force of the third spring 28, the bin door 26 is closed again, which not only avoids the overflow of dust when the construction waste is crushed, but also ensures the comfort of the surrounding environment. It avoids the splashing of fine particles of construction waste duri...

Abstract

The invention discloses a crushing and recycling device for construction waste. The crushing and recycling device for the construction waste comprises a crushing box and a recycling box, a plurality of crushing mechanisms are arranged in the crushing box from top to bottom, the crushing box communicates with the recycling box, a conveying device is arranged in the recycling box, a water tank and ametal collecting box are arranged at the lower end of the conveying device, and a scraping device is arranged on the metal collecting box. According to the crushing and recycling device for the construction waste, by arranging the recycling box, the construction waste crushed by the plurality of crushing mechanisms is guided into the conveying device, in cooperation with a permanent magnet arranged in the middle of the conveying device, separation of concrete and metal is achieved, through the scraping device arranged at the tail end of the conveying device, the metal on a conveying belt is guided into the metal collecting box, recycling and utilizing of the metal is achieved, meanwhile, through a high-pressure spray head arranged at the top of the recycling box, cleaning is carried out on screen holes in the conveying belt, and the screen holes are prevented from being blocked by the concrete, so that continuous separation of the crushed construction waste through the conveying device is achieved.
