Method for preparing ball clay through resource utilization of urban construction engineering muck

Abstract

The invention relates to a method for preparing ball clay through resource utilization of urban construction engineering muck. By means of the method, resource reutilization can be effectively achieved, and the engineering residue soil is changed into ball clay used for ceramic manufacturing in the ceramic field; Meanwhile, in the ball clay preparation method disclosed by the invention, when the mixed slurry is subjected to filter pressing, ball clay with different particles can be subjected to graded filter pressing to obtain ball clay finished products with different finenesses; meanwhile, the flexible linkage mechanism can fluctuate in all directions during filter pressing, so that the whole filter screen can be driven to fluctuate up and down; the filter pressing effect is further enhanced, and blockage of the filter screen is reduced; in addition, the pressure filtration device has the advantages of obvious effect and high applicability.

Description

technical field [0001] The invention belongs to the technical field of urban construction engineering, and in particular relates to a method for preparing ball soil by resource utilization of urban building engineering dregs. Background technique [0002] Ball soil, named after it is pressed into a ball when mined, is an important raw material for the production of ceramic products. The main mineral component of the ball clay is kaolinite supplemented with a certain amount of bentonite, which can make the ball clay have a certain plasticity. With the continuous advancement of urbanization, there are more and more urban construction dregs, and many of the existing engineering dregs include kaolinite, such as Longyan in Fujian and Maoming in Guangdong. Due to its kaolinite The resources are abundant, and most of the excavated engineering slag is kaolinite, and the existing technology multi-processing method for this kind of engineering slag is to be used for landfill in the d...

Problems solved by technology

[0006] In summary, in the prior art, for the method of preparing ball soil, because only the filter press structure of the general prior art is used, and the filter screen in the filter press usually has the problem of clogging, resulting in the prior art The efficiency of preparing ball soil becomes lower and the time becomes longer. At the same time, in the filter press in the prior art, it is not considered that a plurality of different filter screens can be selected according to the difference in particle size during the press filter, so that the press filter Ball soil structures with different particle sizes and diameters are produced to meet the requirements of different application scenarios. At the same time, in the anti-blocking structure of the filter screen, the existing technology only drives the filter screen near the middle part, and there is no strong drive for the edge part. Therefore, the present invention provides a kind of ball soil that can turn waste into treasure, can produce ball soil with different particle sizes according to different particle sizes, can save ball soil preparation time, and prevent ball soil from A method for preparing ball soil by utilization of urban engineering dregs resources when the filter screen is clogged during pressing
