Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of asphalt mould cleaning, and particularly relates to a closed asphalt mould cleaning and waste liquid distillation treatment device. BACKGROUND

[0002] In the production and wide application field of asphalt, such as road paving, building waterproofing and the like, the asphalt mould is used very frequently. However, a large amount of asphalt is often left on the surface of the used asphalt mould, which not only seriously affects the forming quality of the mould in the next use, but also may cause the shortening of the service life of the mould. Therefore, the asphalt mould needs to be effectively cleaned.

[0003] At present, some cleaning methods use organic solvents to clean the asphalt mould. In the cleaning process, the existing cleaning device has poor sealing, and the organic solvent is extremely easy to volatilize. The odor generated by the volatilization of kerosene also pollutes the air environment, which threatens the health of the workers.

[0004] The existing cleaning method does not have an effective waste liquid recovery mechanism. The waste liquid after cleaning contains organic solvents in which asphalt is dissolved. If the waste liquid is directly discharged, it will cause serious pollution to the soil and water body. Moreover, the organic solvent is wasted, and the production cost is increased.

[0005] In addition, the current cleaning device and waste liquid treatment device are mostly independently designed. When the two are integrated into one, if there is no effective linking mechanism between the waste liquid collection link in the cleaning device and the feeding system of the distillation device, leakage and blockage of the waste liquid may occur in the transfer process. At the same time, the flow and temperature of the waste liquid cannot be stably controlled, which affects the working efficiency of the distillation device and cannot effectively separate and recycle the organic solvent.

[0006] In summary, the existing asphalt mould cleaning method and waste liquid treatment have many problems and deficiencies, and need to be improved and optimized. UTILITY MODEL CONTENT
