Stirring cylinder of cold-regeneration stirring apparatus for asphalt mixture

Abstract

The invention discloses an agitating tank of bituminous mixture cold regeneration and agitation equipment, which comprises a tank body and an inlet and an outlet formed on the tank body, wherein two rotatable agitating shafts are arranged inside the tank body; at least three agitating blade devices are arranged on each agitating shaft; each agitating blade device comprises an agitating blade and a holder; the inlet is formed above one end in the axial direction of the agitating shaft of the tank body; the outlet is formed below the other end in the axial direction of the agitating shaft of the tank body; and the plane of the agitating blade and the axial line of the agitating shaft form an included angle Alpha. Compared with the prior art, the inlet and the outlet of the tank body are formed on the two ends in the axial direction of the agitating shaft of the tank body; the agitating blades and the axial direction of the agitating shaft incline to form the included angle; materials to be agitated enter the inlet, are output from one end of the agitating shaft to the other end thereof in a mixed way under the agitating action of the inclined agitating blades, and meanwhile, during the agitating process, the agitating tank can realize continuous feeding after the materials to be agitated are mixed.

Description

technical field [0001] The invention relates to a mixing device, in particular to a mixing cylinder of a mixing equipment for cold regeneration of asphalt mixture. Background technique [0002] Asphalt mixture cold recycling mixing equipment is a mixing equipment used to process asphalt pavement milling materials, and the mixing tank is the heart part of the equipment. The milling material, water, cement, stone powder and emulsified asphalt are fully mixed in the mixing tank to become a qualified asphalt mixture. The inner cavity of the old-fashioned mixing tank is formed by the intersection of two semi-cylindrical bodies. The upper end is the material inlet and the lower end is the material outlet. Such a mixing tank can only be stirred quantitatively. Continuous material supply is greatly limited in actual engineering. At the same time, this kind of mixing tank has a wear-resistant lining plate on the inner wall of the cylinder body. When stirring, the mixing blade direct...

AI Technical Summary

Problems solved by technology

The inner cavity of the old-fashioned mixing tank is formed by the intersection of two semi-cylindrical bodies. The upper end is the material inlet and the lower end is the material outlet. Such a mixing tank can only be stirred quantitatively. Continuous material supply is greatly limited in actual engineering. At the same time, this kind of mixing tank has a wear-resistant lining plate on the inner wall of the cylinder body. When stirring, the mixing blade directly acts on the wear-resistant lining plate to fully mix all materials. , because there is no gap between the blade and the liner, all materials are involved in the mixing, so the material mixing is relatively uniform

The mixing tank cavity is not only complex in shape and relatively difficult to manufacture, but also requires the use of wear-resistant linings, which increases production costs. Users must replace wear-resistant linings regularly during use, which also increases the cost of use.
