Problems solved by technology

[0003] When stirring the expansive soil, if the drying process is not carried out, some expansive soil will be bonded into blocks, which will affect the stirring effect. After that, the expansive soil is transported to the dryer for subsequent drying treatment. The mixing and drying process cannot be carried out at the same time, which greatly affects the work efficiency

Abstract

The invention discloses a stirring device for expansive soil. The stirring device comprises a stirring box and a heat supply box, a circulating drying box is arranged on the side wall of the stirring box, and the heat supply box is connected to the circulating drying box through an air conveying pipe. The device performs double stirring treatment on the expansive soil through cooperation of a stirring roller set and a stirring barrel, the stirring effect is better, and then the expansive soil is conveyed to the top of the inner cavity of the stirring box through the circulating drying box and then is subjected to a new round of stirring treatment; in the expansive soil conveying process, hot air is conveyed to the inner cavity of the circulating drying box through the heat supply box and the air conveying pipe so as to heat and dry the expansive soil, the drying effect is better, and heating is uniform; and meanwhile, the expansive soil can be circularly stirred in the stirring box, the phenomenon that the expansive soil is adhered in the stirring box is effectively prevented, and the practical effect is better.

Description

technical field [0001] The invention relates to the technical field of stirring devices, in particular to a stirring device for expansive soil. Background technique [0002] Expansive soil is a kind of cohesive soil whose volume expands violently after soaking in water, and shrinks significantly after dehydration. The main component is composed of hydrophilic minerals, which have strong expansion and contraction properties. Often patchy, mostly containing calcium or iron-manganese structure. [0003] When stirring the expansive soil, if the drying process is not carried out, some expansive soil will be bonded into blocks, which will affect the stirring effect. Finally, the expansive soil is transported to the dryer for subsequent drying treatment. The mixing and drying process cannot be carried out at the same time, which greatly affects the work efficiency. Contents of the invention [0004] The object of the present invention is to provide a stirring device for expansi...
