Embodiment Construction

[0027] Please also refer to Figure 1 to Figure 5 , as shown in the figure, the mixer for preparing modified emulsified asphalt includes a base 3, an outer cylinder 1 placed on the base 3, an inner cylinder 2 built into the outer cylinder 1, a stirring device 4, and a feed pipe 5 is connected to the inner cylinder 2 through the outer cylinder 1. Feed pipe 5 is a five-channel feed pipe, which is a group of stainless steel temperature control pipes, and is a passage for soap liquid, asphalt, modifier, transition liquid, and filtrate. The stirring device 4 includes a suction swirl volute 41 and a first motor 44 that drives the swirl core 45 inside the swirl volute 41 to work. The first motor 44 acts on the swirl volute 41 through the coupling 43 and the bearing seat 42, wherein the top interface of the swirl volute 41 is connected to the outlet of the lower end of the inner cylinder 2, and the swirl volute 41 has a cage-type swirl core 45. A colloid mill (not shown) is installe...

Abstract

The invention discloses a mixing melting device for preparing modified emulsified asphalt. The mixing melting device comprises a base, an outer cylinder arranged on the base, an inner cylinder arranged in the outer cylinder, a stirring device and a group of material inlet pipes penetrating through the outer cylinder and connected to the inner cylinder, wherein the stirring device comprises a suction type rotational flow volute and a first motor for driving a rotational flow core in the rotational flow volute to work, the top end interface of the rotational flow volute is connected to the outlet in the lower end of the inner cylinder, a cage type rotational flow core is arranged in the rotational flow volute, an internal pressure disperser is arranged in the rotational flow core, a colloidmill is installed behind the rotational flow core, and the mixing melting device further comprises a defoaming device. The invention further discloses a method for preparing modified emulsified asphalt. According to the invention, the problem that asphalt modification and emulsification are completed at a time is solved while the temperature of the asphalt is kept at the normal storage temperature, the extra heating is not needed, and in the whole preparation process, the temperature is within 100 DEG C, such that the raw materials are not affected by high-temperature aging, the product performance is high, and the storage is stable.

Description

technical field [0001] The invention relates to equipment for preparing modified emulsified asphalt, in particular to a mixer for preparing modified emulsified asphalt. It also relates to the use method of the blender. Background technique [0002] SBS modified emulsified asphalt is used for highway pavement and engineering waterproofing. When SBS is used as a modifier to prepare modified emulsified asphalt, SBS and asphalt are generally heated to 180°C, and the SBS modified emulsified asphalt is prepared by high-speed shearing by a shearing machine. Asphalt; then emulsify the SBS modified asphalt, that is, the process of first modifying the asphalt and then emulsifying it. If you want to get high-quality SBS modified emulsified asphalt, you must first prepare high-quality SBS modified asphalt. When preparing SBS-modified asphalt, with the increase of SBS content, the preparation difficulty increases, and the stability of SBS-modified asphalt becomes worse, so the emulsifi...
