The invention relates to asphalt, in particular to a rubber asphalt proportioning method and a rubber asphalt detritus under-sealed layer technique. The method at least comprises rubber, matrix asphalt and single-sized detritus, wherein, the specification of the rubber scrap is 20 meshes, the dosage of the rubber scrap is 20%; the matrix asphalt is selected according to climate areas, number 50-70 can be selected in a hot area; number 70-90 can be selected in a warm area; number 90-110 can be selected in a cold area; the dosage of the matrix asphalt is 77%; the single-sized detritus adopts limestone detritus in 9.5-13.2mm specification, the dosage of the single-sized detritus is 3%; the rubber, the matrix asphalt and the single-sized detritus are blended through processing equipment of the rubber asphalt to form the rubber asphalt. The method comprises the following steps: 1) mixing the asphalt and single-sized detritus; drying and heating the temperature to 150DEG C-160 DEG C; 2) heating the asphalt and the rubber after being heated and dedusted by a mixer plant to 160 DEG C, transmitting the heated asphalt and the rubber to a high speed cutting stirrer for stirring, and heating the stirred asphalt and rubber to 190 DEG C rapidly; 3) cutting the asphalt and the rubber which are cooled to 177 DEG C, transmitting the cut asphalt and rubber to a reaction tank for reacting at least 45 minutes, and carrying out construction after the reacted asphalt and rubber are heated to 200 DEG C.

The invention discloses an amphibious electric balance vehicle structure device and an integrated control method thereof. The amphibious electric balance vehicle structure device comprises wheels, anillumination lamp, a control box, an air cushion, a regulating shaft, a lengthening shaft, a wheel hub motor, an isolation cover, a support post, a pneumatic spring, a protection cover, a state pre-estimation module and an acceleration sensor, wherein a chair is arranged inside an balance vehicle body; the middle part of the bottom end of the balance vehicle body is fixedly connected with the aircushion through screws. The amphibious electric balance vehicle structure device has the advantages that the design is reasonable; the use is convenient; the amphibious use can be realized; through the arrangement of the power wheel in the middle part of the wheel, the wheels can realize the driving effects in water; the wave-resistant performance and the stability are high. The vehicle can conveniently advance in the water; through the arrangement of the regulating shaft, the angle state of the wheels can be changed according to the state pre-estimation signal, so that the running requirementon the pavement and on the water surface can be met; through the arrangement of the balance vehicle body of the waterproof structure, the vehicle can realize the floating in the water; the goal of running in the water is achieved; the state pre-estimation module and the acceleration sensor are arranged on the protection cover, and are used for performing pre-estimation regulation on the stabilityof the balance vehicle body.

The invention provides a wet steam generator water-air mixed sand filter backwash system, which includes a wet steam generator box, a support leg, a heating chamber, a heating wire, a support plate, a stirring gas entering pipe device, and a backwash water storage tank device. Backwash nozzle structure, movable wet steam spray pipe device, waste sand collection bucket structure, flushing water discharge pipe, control cabinet, sand filter layer, reinforcement rod and backwash chamber, the supporting legs are respectively bolted in the wet steam generator The four corners of the lower surface of the box; the heating chamber is integrally arranged at the inner lower side of the wet steam generating box. The setting of the stirring shaft, the stirring rod and the rotating handle of the present invention is beneficial to carry out rotation and stirring, and discharge the gravel entering the air guide row, which facilitates the backwashing operation; the steam water connection is arranged at the lower part of the secondary manual valve, which is beneficial Separate control of backwash water and wet steam water can satisfy both wet steam operation and backwash water.

A method for preparing polyaluminium chloride flocculant with phthalocyanine green wastewater, which is characterized in that: select 335 type weakly basic anion exchange resin and put it into the adsorption column, then use dilute hydrochloric acid to flow through the adsorption column, and then use water or deionized Wash the resin column with water, then treat the resin column with dilute lye, and finally wash the adsorption column with water or deionized water until the effluent is weakly alkaline; adjust the pH value of the phthalocyanine green wastewater to make it between normal temperature and 50°C The 335-type weakly basic anion exchange resin column transformed through the above pretreatment, and then another ion exchange resin adsorption column, can obtain the copper ion concentration meeting the secondary standard in the "Comprehensive Wastewater Discharge Standard GB8978-1996" Phthalocyanine green wastewater: Concentrate the phthalocyanine green wastewater treated with the above resin, add an alkalizing agent to react under the condition of stirring and heating at the same time, adjust the wastewater to be weakly acidic, continue to stir and carry out heating reaction, and obtain the present invention 335 type weakly basic anion exchange resin can also be desorbed and regenerated, which not only recovers resources, but also reuses the resin, saving treatment costs. Realized that the purpose of waste utilization is beneficial to environmental protection.
