Concrete additive raw material collecting device

Abstract

The invention relates to the field of concrete additives, in particular to a concrete additive raw material collecting device, and aims to solve the technical problem about how to provide the concreteadditive raw material collecting device. According to the technical scheme, the concrete additive raw material collecting device comprises an operation platform, an operation control screen, a collecting mechanism, a multi-stage sorting mechanism, a recycling and maintaining mechanism, an elevated workbench and the like; and a conveying belt, the collecting mechanism, the multi-stage sorting mechanism, the elevated workbench and the operating platform are sequentially connected to the upper side of a working machine bottom plate. According to the device, efficient cleaning and separation of microbial films on the surfaces of volcanic rock are achieved, volcanic ash and zoogloea in small holes of the volcanic rock are separated, the volcanic ash is separated and collected in a flotation manner, the microbial films are dissolved, pure volcanic rock is separated out, and adhesive zoogloea is separated from the device, so that the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the field of concrete additives, in particular to a device for collecting raw materials of concrete additives. Background technique [0002] Volcanic rock is a kind of vitreous lava with dense pores formed after the magma is cooled rapidly during the volcanic eruption. Due to the sharp decrease in pressure, the internal gas overflows and expands rapidly. Its pore volume accounts for more than 50% of the rock volume. It is called pumice because of its many pores, light weight, and ability to float on water. It is characterized by high strength, heat preservation, heat insulation, sound absorption, fire prevention, acid and alkali resistance, corrosion resistance, and no pollution and radioactivity. [0003] At present, volcanic ash is an important building material. In the prior art, after the volcanic rock is formed, volcanic ash will accumulate in the small holes of the volcanic rock. When the volcanic rock is ejected to the...

AI Technical Summary

Problems solved by technology

[0005]In order to overcome the volcanic ash that will accumulate in the small holes of the volcanic rock after it is formed, when the volcanic rock is ejected to the foot of the volcano, the volcanic rock is relatively humid at the foot of the volcano. In the environment, because its own porous structure is conducive to the reproduction of microorganisms, gelatinous bacteria clusters will grow inside the small holes, and the volcanic ash will be blocked in the small holes. With the rapid reproduction of bacteria, a layer of microbial film that is difficult to remove is formed on the surface of the small holes. This kind of microbial film completely covers and wraps most of the small holes on the surface of the volcanic rock, which leads to the fact that the volcanic ash inside the small holes cannot be separated and extracted by simple water washing and vibration methods during the volcanic rock extraction operation, and the volcanic ash inside the small holes cannot be extracted. The shortcoming that is fully utilized, the technical problem of the present invention is: provide a kind of concrete additive raw material collecting device
