Problems solved by technology

[0002] The amount of construction waste in my country has accounted for 30%-40% of the total amount of urban waste. Calculated based on the standard of 500-600 tons / 10,000 square meters, by 2020, my country will increase the construction area by about 30 billion square meters. The construction waste generated will be a shocking figure. However, most of the construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is piled up in the open air or landfilled. At the same time, problems such as dust, dust and sand flying in the process of clearing, transporting and stacking have caused serious environmental pollution.
[0003] In the process of recycling and reusing construction waste, it is necessary to crush the construction waste. The traditional crushing device cannot finely crush the construction waste. Recycling of construction waste

Embodiment 1

[0023] see Figure 1~4 In an embodiment of the present invention, a crushing device for recycling construction waste includes a crushing box 1 and crushing rollers 2; the crushing box 1 is provided with multiple groups of crushing rollers 2 arranged longitudinally, and the crushing rollers 2 are connected to each other through a transmission shaft 3 The inner wall of the crushing box 1 is rotationally connected, the transmission shaft 3 extends to the outside of the crushing box 1 and is connected to the first drive motor 4 through a coupling, and the first drive motor 4 is fixedly connected to the crushing box 1 by means of bolts; the crushing roller 2. There is an upward convex screen cover 5 at the bottom. The upward convex screen cover 5 is a hollow conical screen cover for preliminary screening of the broken concrete blocks, and small particles of concrete enter the upper convex screen through the screen holes. In the screen cover 5, the concrete blocks of large particles...

Embodiment 2

[0028] see figure 1 and Figure 5 The difference between this embodiment and Embodiment 1 is that: the upper end of the crushing box 1 is connected with a feeding hopper 14 through a feeding box 15, and a feeding impeller 16 is arranged in the feeding box 15, and the feeding impeller 16 includes a driven shaft 17 And the rectangular blades distributed in the circumferential direction, the driven shaft 17 extends to the outside of the lower material box 15 and is connected to the transmission shaft 13 through the second transmission belt 18. When crushing, the feeding speed of the concrete block is controlled to ensure the crushing effect. At the same time, it reduces dust spillage and protects the environment.

Abstract

The invention discloses a crushing device for recycling construction waste. The crushing device comprises a crushing box and a crushing roller, an upper convex screen cover is arranged below the crushing roller, a grinding disc is fixedly connected to the lower end of the upper convex screen cover; a grinding disc matched with the grinding disc is arranged on the outer side of the grinding disc, alower convex screen cover is arranged below the grinding disc, and a crushing blade group is arranged in the lower convex screen cover. The upper convex screen cover and the grinding disc with the through holes are arranged, so that the crushed concrete blocks are screened and separated, the subsequent grinding is facilitated, the grinding efficiency is improved, by arranging the lower convex screen cover and the crushing blade set, the ground concrete particles are further crushed, meanwhile, the crushing effect is ensured through the lower convex screen cover.

Description

technical field [0001] The invention relates to the field of construction waste recovery equipment, in particular to a crushing device for construction waste recovery. Background technique [0002] The amount of construction waste in my country has accounted for 30%-40% of the total amount of urban waste. Calculated based on the standard of 500-600 tons / 10,000 square meters, by 2020, my country will increase the construction area by about 30 billion square meters. The construction waste generated will be a shocking figure. However, most of the construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is piled up in the open air or landfilled. At the same time, problems such as dust, dust and sand flying in the process of clearing, transporting and stacking have caused serious environmental pollution. [0003] In the process of recycling and reusing construction waste, it is necessary to crush the construction waste. The t...
