Efficient gravel screening water recycling device

Abstract

The invention discloses an efficient gravel screening water recycling device which comprises a feeding pipe, a grid, a liquid level meter, a tank, a water inlet pipe, a flow meter, a spray head, a rotating shaft, a camera, a timer, impellers, a sieve plate, a vibration exciter, a coarse sand discharging pipe, a fine sand discharging pipe and a return pipe, wherein the feeding pipe is arranged at the top of the tank, the grid is arranged obliquely in the feeding pipe, the tank is communicated with the water inlet pipe, the spray head is arranged at the outlet end of the water inlet pipe, the rotating shaft is arranged in the tank, the impeller is mounted on the rotating shaft which is connected with an external motor, the sieve plate is arranged obliquely in the tank, the lower surface of the sieve plate is provided with the vibration exciter, and the upper surface of the sieve plate is provided with a friction strip. The sieve plate comprises a first sieve plate and a second sieve plate, a stirring shaft is arranged between the first sieve plate and the second sieve plate and provided with a plurality of groups of impellers of different sizes, the bottom end of the tank is connected with one end of the return pipe, and the other end of the return pipe is communicated with the water inlet pipe. The efficient gravel screening water recycling device screens gravels, improves working efficiency, saves time and labor, and is simple in structure, convenient to use and favorable for popularization.

Description

Technical field [0001] The invention relates to a washing device, in particular to a high-efficiency sand and gravel screening water recycling device. Background technique [0002] Because of its good hardness and stable chemical properties, sand and gravel are often used as high-quality building materials and concrete raw materials and are widely used in housing, roads, highways, railways, engineering and other fields. With the requirements of infrastructure construction technology and the development of high technology, there are higher requirements for the quantity and quality of sand and gravel. Sand and gravel are loose materials, but their particles are generally harder and chemically stable under the surface environment. For sandstone, its resistance to weathering is generally strong, especially for silicified quartz sandstone, whose hardness exceeds that of granite. Sand and gravel is the basic material in the national economic construction, mainly used in basic enginee...

AI Technical Summary

Problems solved by technology

It has different effects on sand and gravel of different sizes. The existing sand and gravel screening work is inefficient and difficult to meet the needs of increasingly prosperous production and life.
