A high-efficiency separation sand screening device

Abstract

The invention discloses an efficient separation sand sieving device comprising a sieve drum, a feed pipe and a driving motor. A linear rotary sieve plate is arranged in the sieve drum and is fixedly connected with a third driven shaft. The third driven shaft extends to the outer side of the sieve drum and is connected with a second driven shaft through a second transmission belt. The bottom of thesieve drum is provided with an arc-shaped through groove. A bottom sieve plate is nested in the arc-shaped through groove. The two sides of the sieve drum are fixedly connected with struts. A sand guide plate is arranged below the bottom sieve plate. A stone discharge pipe is arranged on the right side of the sieve drum and is in tangency with the upper end of the sieve drum. The efficient separation sand sieving device is provided with the sieve drum, the rotary sieve plate, the stone discharge pipe and the bottom sieve plate, and the stone discharge pipe and the bottom sieve plate are in tangential communicating, thus efficient centrifugal separation of fine sand and impurity particles is achieved, sieving efficiency is improved, and meanwhile the fine sand and the impurity particles are separated conveniently. The efficient separation sand sieving device is provided with the feed pipe and a spiral feed roller, so that feed speed is controlled, and the sieving effect is ensured.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a high-efficiency separation sand screening device. Background technique [0002] The sand sieving machine imitates the working principle of artificially using the inclined screen to screen sand. It adopts a flat rolling screen cylinder and ensures that the material flow can be continuously rolled for more than five circles between the multi-turn inner spiral blades in the screen cylinder, so that the sand material can be repeatedly screened. It is fully discrete and separated by tumbling and sliding; it is different from the pushing and burying of large and small materials caused by inclined roller sieves, and the screening process is rushed; it is also different from the vibration and mixing of large and small materials caused by inclined vibrating screens. The traditional sand screening machine screens through the vibrating sieve plate, and the impurity particles roll alo...

AI Technical Summary

Problems solved by technology

The traditional sand screening machine screens through the vibrating sieve plate, and the impurity particles roll along the sieve plate to the bottom. The separation efficiency of the impurity particles and the fine sand is low, resulting in low screening efficiency. In addition, the impurity particles are easy to block the sieve holes during the screening process to clean up
