Example Embodiment

[0028] The invention provides a double-horizontal-shaft forced mixer with an adjustable mixing unit, which is particularly suitable for efficiently producing high-quality and diversified asphalt concrete. Its structure is shown in Fig. 1 and Fig. 2, and includes: a horizontal mixing cylinder 2, which is horizontally fixed and supported on a frame 1. The barrel 2 forms a chamber for containing the materials to be stirred, and the barrel 2 has a feeding mechanism and a discharging mechanism. The two stirring shafts 3 are rotatably supported on the stirring cylinder 2 in the axial direction. The rotation axes of the two stirring shafts 3 are in the same plane and parallel to each other. The two stirring shafts 3 are driven by the driving device 7 to rotate synchronously in opposite directions. Each agitating shaft is provided with a plurality of agitating units spaced in the axial direction and sequentially deviated from a certain angle in the circumferential direction to form a spir...

Abstract

A compulsory mixer provided with an adjustable mixing unit comprises a horizontal mixing cylinder body, a mixing shaft which can act as support rotationally along the axial direction and a plurality of mixing units which are spaced along the axial direction and arrayed in a screwed manner with deviating from the mixing shaft at different angles in sequence in the circumferential direction. The mixing unit comprises a mixing arm and a mixing blade. A mounting hole extending in the direction of length is arranged on the mixing arm. The mixing arm is connected with the mixing shaft by a dismountable sleeve. The mixing blade is flexibly fixed on the mixing arm by a fastening component that goes through the mounting hole. And a tooth part arranged between the mixing blade and the contact face of the mixing arm is used for locating the mixing blade and the contact face of the mixing arm. The intervals, installation angles and number of the mixing units can be adjusted according to the requirement for mixing. In addition, the mixing unit can be moved in the direction of the length of the mixing arm and the installation position of the mixing blade also can be adjusted, thus meeting the diversified demands placed on mixing asphalt concrete to achieve the best effect of mixing and highest mixing efficiency.

Description

technical field [0001] The invention relates to a forced mixer, especially a twin-shaft forced mixer used for asphalt concrete mixing, which has an adjustable mixing unit. Background technique [0002] As is known, forced mixers are widely used in highway and construction engineering for material mixing, for example, twin-shaft forced mixers are preferably used in asphalt concrete mixing operations. Use a forced mixer to mix the measured gravel, gravel, stone chips or sand, mineral powder, etc. with a certain gradation and a certain proportion of road asphalt materials to make a mixture that meets different construction requirements. [0003] Recently, the research and development of the forced mixer has been paid attention to by the industry, and the mixing performance, production capacity and reliability have been greatly improved. However, in order to produce high-quality asphalt concrete economically and efficiently, the existing forced mixer still needs to be further i...
