Description

Technical Field

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

[0002] Emulsified asphalt is a viscous asphalt dispersed in water containing an emulsifier and a stabilizer in a droplet state through heat melting and mechanical action to form an oil-in-water (O / W) asphalt emulsion. Emulsified asphalt is a road construction material that is usually used at high temperatures, diffused into water through mechanical stirring and chemical stabilization (emulsification) to liquefy into a very low viscosity and good fluidity at room temperature. It can be used at room temperature and can also be used with cold and wet stones.

[0003] Emulsified asphalt is a thermodynamically unstable system and should be stored at high or low temperatures; it is usually required to be between 5 and 50°C. At the same time, it needs to be stirred regularly to make it uniform. The Chinese authorized patent document with publication number CN217457238U relates to an emulsified asphalt storage device, including a storage tank body, a discharge pipe, a stirring motor, a stirring shaft, support legs and a plate-shaped stirring blade, and the discharge pipe is arranged on the outside of the storage tank body, the stirring motor is installed on the surface of the storage tank body, the stirring shaft is connected to one end of the stirring motor, the plate-shaped stirring blade is installed on the outside of the stirring shaft, and the support legs are connected to the outside of the storage tank body. The utility model is provided with a second scraper, a connector and a pulling assembly, and when the asphalt in the storage tank body is discharged, the asphalt remaining on the outside of the plate-shaped stirring blade can be scraped off more fully, so as to quickly discharge this part of the asphalt from the storage tank body, and it can also prevent the asphalt from adhering to and condensing on the outside of the plate-shaped stirring blade.

[0004] The above-mentioned prior art cannot quantitatively adjust and control the storage temperature of emulsified asphalt, and the absence of a circulating pumping device easily causes oil-water separation and upper and lower stratification of the emulsified asphalt. Therefore, it is necessary to develop a new type of emulsified asphalt storage device. Utility Model Content

[0011] Preferably, a discharge pipe is installed at the bottom end of the storage tank body, a discharge control valve is installed outside the discharge pipe, and the outer surface of the storage tank body is coated with a heat-insulating paint structure layer.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model adjusts the temperature of the storage tank by setting a cavity, and is provided with an electric heating control tube, a temperature sensor and a temperature adjustment knob device. The temperature adjustment knob device can be used to adjust the electric heating control tube to a suitable heating temperature, so that the storage temperature of the emulsified asphalt is relatively constant, which can effectively reduce the influence of the external ambient temperature on the emulsified asphalt. At the same time, a stirring device and a circulation device are provided to delay stratification, and a stirring rod is used to continuously stir the emulsified asphalt inside the tank body.
