A stone powder processing device for green environmental protection machine-made sand production

Abstract

The invention belongs to the technical field of stone powder treatment, and in particular relates to a stone powder treatment device for green and environmentally friendly machine-made sand production, which includes a feeding module, a processing module, and a transportation module. The upper side of the transport mechanism will not have friction and wear with the inner wall of the processing shell. The function of the filter ring designed in the present invention can prevent stone powder from entering the upper end of the first passage, causing damage to the first air pump. The invention makes the machine-made sand falling from the hopper fall in a relatively thin shape in the radial direction of the treatment shell through the design of the width of the feeding hole, so as to ensure that the stone powder in the falling machine-made sand is blown by the gas in the first air pipe , most of the stone powder can enter the second channel from the third air hole opened on the third channel on the treatment shell, so as to ensure that the stone powder in the machine-made sand can be mostly cleaned up and improve the quality of the machine-made sand.

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.
