Centrifugal sand grain separation device and implementation method

Abstract

The invention relates to a centrifugal sand grain separation device and an implementation method. The centrifugal sand grain separating device comprises a speed regulating motor, a feeding device, a discharging device, a primary separation device, a secondary separation device, a collecting device and a conveying device. The primary separation device consists of a bulk material disc and a bulk material range controller, wherein the bulk material disc is a steel conical barrel or a steel disc connected with a main shaft of the motor, and the bulk material range controller consists of a steel cylinder and a steel truncated cone cylinder. The secondary separation device is a bulk material disc connected with the main shaft of the motor, the size of the bulk material disc is greater than thatof a primary bulk material disc, and the secondary separation device is a steel disc or a steel fan blade capable of adjusting angles. The centrifugal sand grain separation device can effectively separate sand grains with the grain size more than or less than certain grain size (a controlled diameter) so that separated sand materials meet the requirements on engineering application. The centrifugal sand grain separation device has the advantages of the separation of thick and thin sand grains, high automation degree, time and labor saving, simple structure, durability, easy repair, large treatment quantity and high separation efficiency.

Description

technical field [0001] The invention relates to sand sorting equipment, in particular to a centrifugal sand separation device and a realization method. Background technique [0002] Sand is an important engineering material in construction engineering. In recent years, due to the rapid development of my country's capital construction projects, the qualified sand sources used in civil construction projects have been gradually exhausted. There are few particles, it is difficult to meet the requirements of engineering use, and further screening is required. [0003] In recent years, rich oil resources have been explored in many desert regions in my country and the world. Petroleum development is inseparable from capital construction, and capital construction cannot be separated from concrete. Due to the special conditions of the desert, the stones used for concrete can only be transported from outside the desert at present, and the huge transportation cost has greatly increas...

AI Technical Summary

Problems solved by technology

Even if a small number of projects with high requirements are used to sort sand, water washing or winnowing is generally used. Due to the limitations of sewage treatment and environmental pollution, these methods do not have the value of general application

At the same time, manual screening has the problems of low efficiency and high labor intensity, and the traditional sand sorting machine is not suitable for the problem of desert with more fine sand and less coarse sand due to the angle and density of the screen surface
