Description

Technical Field

[0001] The utility model relates to the technical field of asphalt processing, in particular to an asphalt emulsification preparation device. Background Art

[0002] Asphalt emulsification is the process of converting viscous asphalt into liquid asphalt through a specific process. Its primary purpose is to improve asphalt's workability and expand its application. Emulsified asphalt is a process in which viscous asphalt is dispersed as droplets in water containing an emulsifier and stabilizer through thermal melting and mechanical action, forming an oil-in-water asphalt emulsion. The emulsifier plays a key role in this process, connecting the two immiscible systems of asphalt and water, reducing the surface tension at the asphalt-water interface and allowing the asphalt to disperse as tiny particles in the aqueous solution, forming a relatively stable mixture.

[0003] Emulsified asphalt does not require high-temperature and long-term heating during the production process. On the contrary, emulsified asphalt generates a lot of latent heat during production. If the emulsified asphalt is directly put into the finished product tank, the heat will be dissipated at will, which will cause energy waste and be detrimental to environmental protection. Utility Model Content

[0004] The utility model aims to solve the above-mentioned technical problem that the latent heat generated by emulsified asphalt is not effectively utilized, which is not conducive to environmental protection, and provides an asphalt emulsification preparation device.

[0006] A heat exchanger is provided on the bottom plate, and a heat recovery assembly is provided between the heat exchanger and the preparation tank and the storage tank. The heat recovery assembly includes a discharge pipe provided at the lower end of the preparation tank, a pump is provided on the discharge pipe, and the discharge pipe is connected to a branch pipe 1 and a branch pipe 2 through a tee pipe fitting; the branch pipe 1 extends into the heat exchanger and coils in a serpentine shape, and the end portion extends out of the heat exchanger and extends into the storage tank; the end portion of the branch pipe 2 extends into the storage tank; the branch pipe 1 is provided with a solenoid valve 1, and the branch pipe 2 is provided with a solenoid valve 2;

[0007] A water inlet pipe is provided at the upper end of the heat exchanger, and a water volume control structure is provided on one side of the heat exchanger; a water delivery pipe is provided between the heat exchanger and the preparation tank.

[0008] Furthermore, a driving motor is provided at the upper end of the preparation tank, and an output end of the driving motor extends into the preparation tank and is provided with a shear stirring structure.

[0009] Furthermore, the emulsifier tank and the matrix tank are both connected to the preparation tank through a transmission pipe.

[0010] Furthermore, the water volume control structure includes a control pipe connected to the lower end of the heat exchanger, and the control pipe is Z-shaped, with the end extending to the outside of the heat exchanger.

[0011] Furthermore, a heat-insulating cavity is provided in the storage tank, and a thermometer is provided on the storage tank.

[0012] Furthermore, a control panel is provided in the control box, and the control panel is electrically connected to the first solenoid valve and the second solenoid valve via a wire.
