Green and environment-friendly stone powder treatment device for machine-made sand production

Abstract

The invention belongs to the technical field of stone powder treatment, and particularly relates to a green and environment-friendly stone powder treatment device for machine-made sand production. The green and environment-friendly stone powder treatment device for machine-made sand production comprises a feeding module, a treatment module and a transportation module. According to the green and environment-friendly stone powder treatment device for machine-made sand production provided by the invention, machine-made sand can directly fall to the upper side of a transportation mechanism in the stone powder removal process, and friction abrasion between the machine-made sand and the inner wall of a treatment shell is avoided. A filter ring designed in the invention can prevent stone powder from entering the upper end of a first channel to damage a first air pump. According to the green and environment-friendly stone powder treatment device for machine-made sand production provided by the invention, through the design of the width of a discharging hole, the machine-made sand falling from the discharging hopper falls in the radial direction of the treatment shell in a thin form, so that after the stone powder in the falling machine-made sand is blown by air in a first air pipe, most of the stone powder can enter a second channel from third air holes formed in a third channel in the treatment shell, the most of the stone powder in the machine-made sand can be ensured to be removed, and the quality of the machine-made sand is improved.

Description

[0001] Technical field [0002] The invention belongs to the technical field of stone powder treatment, and in particular relates to a stone powder treatment device for green and environment-friendly machine-made sand production. Background technique [0003] Machine-made sand refers to sand processed by sand making machines and other auxiliary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different process requirements, which can better meet daily needs. Machine-made sand requires professional equipment to produce qualified and suitable sand and gravel. With the strengthening of environmental protection policies and the tightening of the ban on river sand excavation, machine-made sand has gradually become the mainstream of construction sand. [0004] In the process of machine-made sand manufacturing, it is necessary to control the stone powder in the machine-made sand. Generally, water washing is used...

AI Technical Summary

Problems solved by technology

[0004] In the process of machine-made sand manufacturing, it is necessary to control the stone powder in the machine-made sand. Generally, water washing is used to control the content of the stone powder. As a result, water resources are wasted and new pollution is generated. After the implementation of the new national standard, there is no need for stone powder in the machine-made sand. Clear requirements and experimental methods. Before raw material processing, soil removal treatment should be carried out first. After that, the stone powder should be removed and collected by special equipment to improve the added value of the product. At present, the processing equipment of stone powder has the following problems: the impact of sand on the equipment The wall surface has certain wear and tear, and the sieve hole is too small, which is easy to block and difficult to clean. The treated sand cannot be discharged well, and the removal rate of stone powder in a single process is low, requiring more processes.
