Environment-friendly stone screening system

Abstract

The invention provides an environment-friendly stone screening system. The environment-friendly stone screening system comprises a stone washing device, a first conveying pipe, an input valve, a dry method powder removal device, a second conveying pipe, an output valve and a precipitation pool. The stone washing device is fixed to the ground. A discharge port of the stone washing device is connected with a feed port of the dry method powder removal device through the first conveying pipe. A discharge port of the dry method powder removal device is connected with the precipitation pool through the second conveying pipe. The input valve is arranged in the first conveying pipe. The output valve is arranged in the second conveying pipe. According to the environment-friendly stone screening system, dry type powder removal is adopted, pebbles are subjected to dust suction through the motor dry method powder removal system instead of being washed with high-pressure water when passing through the stone washing device, and the pebbles enter the precipitation pool. The environment-friendly stone screening system is low in energy consumption, small in water consumption and obvious in environment-friendly effect and solves the problem of environment pollution.

Description

technical field [0001] The invention relates to an environment-friendly stone screening system, and relates to a high-strength concrete stone cleaning machine in the building material industry. Background technique [0002] At present, there are nearly 700 prestressed concrete pipe pile companies in China, but the requirements for raw materials are very high in the process of producing prestressed concrete pipe piles. Among them, the main material stone must be distributed according to the size of the area and must not be stained with dust. Existing prestressed concrete pipe pile companies generally use a screen type stone washing machine to screen stones, on which a high-pressure water pump is installed to wash the stones with high-pressure water when the stones pass through the screen. Based on the production of 10,000 meters of pipe piles per day, the water consumption for washing stones is about 200 tons, which means that nearly 200 tons of sewage will be produced every ...

AI Technical Summary

Problems solved by technology

Based on the production of 10,000 meters of pipe piles per day, the water consumption for washing stones is about 200 tons, which means that nearly 200 tons of sewage will be produced every day, and energy is wasted. too bad

In order to evade environmental protection inspections, buried pipes are mostly used, and sewage pumps are used to secretly drain water into the river, the sea or nearby hidden low-lying areas, resulting in serious complaints from residents, and the environment cannot be improved. The environmental protection problem is only a formality. Not in place
