The application relates to a modular three-dimensional garage facilitating bicycle storage, and belongs to the technical field of traffic facilities. The garage frame is formed by splicing a plurality of standard modules through a unified interface. The transmission of bicycles is realized by the gear and rack mechanisms of mutual connection between the modules. The system has key module quantity identification and module topology identification functions, and the connected module quantity is detected in real time through PLC. During operation, the system cooperates with motors and sensors based on the automatically generated layout, and follows the logic of first moving horizontally to clear the channel and then lifting to adjust the parking position to complete accurate storage and taking. The core feature of the application is that the modular design thought of standardized units and expandability is adopted, the number of frame can be flexibly increased or reduced according to the size of the urban fragmented space, on-demand expansion is realized, and the site adaptability and reconstruction flexibility of the three-dimensional garage are improved.

The invention relates to the technical field of chemical sewage, discloses a pretreatment method of chemical sewage, and solves the problems of high treatment cost, low organic matter removal rate and poor resource utilization rate of existing production sewage of anthranilic acid, methyl anthranilate and saccharin sodium salt. According to the method, the sewage is subjected to salt component pretreatment, so that interference of inorganic salt on subsequent reaction is eliminated; then carrying out hydrolysis / alkaline hydrolysis treatment; then, through diazotization-coupling reaction, anthranilic acid components are directionally converted into 2-((5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl) diazo) benzoic acid by-products with high additional value; and finally, cooling is carried out, and a phthalic acid crude product is separated out and recovered from the 2-((5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl) diazo) benzoic acid by-products. The utilization rate of anthranilic acid components in the sewage reaches 99.9% or above, and meanwhile the method has the advantages of being low in treatment cost, small in equipment investment, short in technological process, high in resource benefit and thorough in sewage treatment.

The utility model discloses a household garbage and stale garbage synergistic treatment system which comprises a stale garbage feeding hopper, a double-layer roller dryer, a crushing and conveying assembly and a stale garbage discharging hopper. The double-layer roller dryer comprises an outer cylinder and an inner cylinder, the inner cylinder is embedded in the outer cylinder, and the two ends of the inner cylinder are connected with the stale garbage feeding hopper and the stale garbage discharging hopper correspondingly so that stale garbage can enter and exit from the inner cylinder; a spiral conveying assembly is arranged in the inner cylinder so that stale garbage can move in the inner cylinder. A dead steam inlet and a dead steam outlet are formed in the two ends of the outer cylinder correspondingly, dead steam is introduced from the steam turbine side, and stale garbage is dried; dry stale garbage output by the stale garbage discharging hopper is conveyed to the crushing and conveying assembly, is crushed and then is conveyed into the garbage incinerator to be mixed with household garbage for combustion. The device has the advantages of convenience in use, high treatment efficiency, low cost and the like, and solves the problem that the treatment cost of stale garbage is high due to the fact that the existing equipment is too complicated.
