The invention discloses a wax and paper separation process for waste wax cartons and application of the wax and paper separation process, and belongs to the technical field of paper making. The wax and paper separation process includes the following steps: (1) the waste wax cartons are collected into a pulper; (2) pulping is conducted, specifically, a solvent and lye are added, and meanwhile, an intermittent pulping mode is adopted; (3) heavy slag is removed; (4) coarse sieving is conducted; (5) grading sieving is conducted; (6) fine sieving is conducted; and (7) secondary treatment of good long fiber pulp is conducted. The pulper is a hydraulic pulper, and the rotating speed of the pulper is 300-500 r/min; the solvent is water or pulping white water or a mixture of the water and the pulping white water, the temperature of the solvent is 45-55 DEG C, and the additive amount of the solvent enables the concentration of wax paper to be 8-12%; and the lye includes but is not limited to a caustic soda or potassium hydroxide solution. According to the wax and paper separation process, wax and paper on the wax cartons can be effectively separated, paper fiber after separation of the wax can serve as a raw material for manufacturing the cartons, the obtained cartons have good compressive strength, and the industry use standard is met.

The invention discloses an intelligent garbage can management system based on automatic classification, and particularly relates to the technical field of intelligent garbage can management. Humidityof garbage thrown into a garbage can is collected through a humidity sensor, and an instruction is sent into a control module according to a judgment result, so that the control module controls an output shaft of a motor to rotate forwards or reversely; the garbage is thrown into two can bodies in a classified mode, and when a capacity sensor senses that the can bodies are full of the garbage, information is transmitted to a cloud server through a wireless communication module, then the information of the garbage can is transmitted to a mobile terminal, workers are informed to clean the garbage in the garbage can, and a planned route map is sent to the mobile terminal, and workers can conveniently and quickly reach the position of the garbage can, so that the working efficiency of cleanersis greatly improved, the labor intensity of the cleaners is reduced, centralized management and unified display of information such as positions, states and usability of a large number of garbage cans by environmental protection departments are facilitated, and the construction of smart cities is facilitated.
