Energy-saving and environment-friendly concrete sandstone separator

Abstract

The invention relates to an energy-saving and environment-friendly concrete sandstone separator, and belongs to the field of sandstone separators. The energy-saving and environment-friendly concrete sandstone separator comprises a machine body, a screening mechanism is arranged in the machine body, one end of the machine body is provided with a stone outlet and a sand outlet, the stone outlet and the sand outlet are located at the end, away from a feeding hopper, of the machine body, and a blow-off pipe is arranged at the end, close to the bottom, of the machine body; the screening mechanism comprises a screen drum rotationally connected into the machine body, a first fixing frame and a second fixing frame are fixedly arranged at the two ends of the screen drum respectively, a driving assembly for driving the screen drum to rotate is arranged at the end, close to the first fixing frame, of the machine body, and a power assembly for driving the screen drum to vibrate is arranged at the end, close to the second fixing frame, of the machine body; and the power assembly comprises a power motor fixedly arranged on the outer side wall of the machine body, a polygonal inserting block is fixedly arranged on an output shaft of the power motor, a bearing is fixedly arranged in the second fixing frame, a true polygonal clamping groove is formed in the bearing, and the inserting block is inserted into the clamping groove of the bearing. The energy-saving and environment-friendly concrete sandstone separator has the effect of preventing the screen holes of the screen from being blocked.

Description

technical field [0001] The present application relates to the field of sand and gravel separators, in particular to an energy-saving and environment-friendly concrete sand and gravel separator. Background technique [0002] In the process of rapid social development, saving resources, protecting the environment, and maintaining the sustainable development of society are increasingly concerned by the whole society. Commercial concrete as a construction of social infrastructure is also developing rapidly. In the production process of ready-mixed concrete, it is necessary to wash the mixer and transport the tanker, which will generate a large amount of waste water and waste residue. These waste water and waste residue are usually discharged directly without treatment, causing great pollution to the environment. The sand and gravel separator is the core equipment of the wet concrete recovery system. It is mainly used to clean, separate and recycle the sewage from cleaning tank ...

AI Technical Summary

Problems solved by technology

[0004]However, after the common sand separator is used, the sand attached to the filter is difficult to clean, and the particle size of some sand is close to the pore size of the screen. Sand and gravel are easy to block the screen, thus affecting the filtration efficiency of the screen
