The invention relates to a municipal refuse classification processing method, which comprises a plurality of steps of (1) primary separation that the garbage which can be treated solely is separated from municipal refuse, (2) primary fragmentation, (3) one-time separation that the garbage material is divided into weight material mainly comprising inorganic substances and soft material mainly comprising organic compounds, (4) crushing of weight material, (5) magnetic separation of weight material that the weight material is divided into magnetic weight material and non-magnetic weight material, and (6) crushing of soft material; wherein, the metallurgy mineral processing of magnetic weight material is processed; the separated fine mineral sand is adopted as metallurgy material; the separated mine tailing is mixed with the non-magnetic weight material and treated together; the non-magnetic weight material is applicable to architecture materials and filler; the crushed soft material is applicable to fuel, marsh gas, compost or fertilizer. The municipal refuse classification processing method has the advantages of adopting most of municipal refuse as recyclable material to classify and treat, and facilitating the resource utilization of most municipal refuses.

The car flexible side-frame material box comprises a base, straight slide rails, slide blocks and limiting supports, wherein the limiting supports are mounted on the slide blocks, and comprise the first limiting support and the second limiting support, the straight slide rails are mounted on the base, and the slide blocks are mounted on the straight slide rails and can move on the straight slide rails; and front-rear-direction position adjustors are mounted on the slide blocks, height-direction adjustors are mounted on the first limiting support, the height-direction adjustors are used for adjusting the height of the first limiting support, and rotatable left-right-direction limiting adjustors are mounted on the second limiting support. The car flexible side-frame material box has the beneficial effects that the compatibility of material box is achieved, the quantity of material boxes is reduced, the cost is saved, the valuable location resource is saved, furthermore, the structure is simple, the cost is low, and maintenance is simple.

The invention discloses an integrated transmission line protection and traveling wave distance measurement method. Through a protection DSP unit starting criterion and traveling wave DSP unit starting combination, the frequent false starting of traveling wave distance measurement is effectively reduced, through dividing a high speed cache unit into four cache sub units to store traveling wave distance measurement data in a circulated way and timely storing the traveling wave distance measurement data of each time to a data storage device, thus the multiple times of traveling wave distance measurement data with near initiation intervals are not covered, a problem of data coverage or loss caused by frequent starting is effectively solved, through a mode of setting two types of extraction sampling units, the precision of protecting DSP sampling is improved, the fault distance measurement precision of a transmission line is improved, at the same time station resources are saved, and the method has a good application prospect.

The invention discloses a permeable brick prepared from serpentine tailings and construction waste and a preparation method thereof. The present invention selects serpentine tailings and construction waste as raw materials, carries out crushing, screening, and grading, uses high-efficiency binders and solid waste particles to form moldings, and maintains finished products. The prepared non-sintering permeable bricks are better than the indicators specified in national standards. Requirements, not only can make full use of solid waste serpentine tailings and construction waste, but also greatly increase the added value of solid waste, realize the resource recycling of solid waste, reduce the site resources occupied by landfill, It has important economic, social and ecological significance.

The invention relates to the field of comprehensive utilization of solid waste resources and the field of preparation of inorganic non-metallic materials, and in particular, relates to a multi-scale pore honeycomb ceramic and a preparation method thereof. The multi-scale pore honeycomb ceramic comprises the raw materials: fly ash, an additive and a pore-preparing agent, wherein the pore-preparingagent is composed of a foaming agent and a pore-forming agent, the foaming agent is silicon carbide, and the pore-forming agent is nano silicon carbide. The preparation method of the multi-scale porehoneycomb ceramic comprises the steps: (1) mixing fly ash, an additive and the pore-preparing agent, and then carrying out ball milling, aging and secondary pugging to obtain pug; (2) carrying out extrusion molding on the pug through an extruder to prepare a honeycomb ceramic green body; and (3) drying the honeycomb ceramic green body, and sintering. According to the invention, the high-valued utilization of solid waste fly ash is realized, the additional value of the fly ash is increased, the manufacturing cost of the multi-scale porous honeycomb ceramic is reduced, and the performance of themulti-scale porous honeycomb ceramic is further improved.

The invention discloses a method for hoisting, roasting and casting a strip continuous casting flow distribution device. The method comprises the following steps that: 1) the flow distribution device is arranged at two ends of the bottom of a tundish vehicle through a hanging mechanism, a distributor is arranged at the bottom of the tundish vehicle and inserted into the flow distribution device, and the tundish vehicle drives the flow distribution device and the distributor to move up and down; 2) during roasting, a roasting pit has an independent temperature control system, and gas nozzles are arranged on the periphery inside the roasting pit; 3) hot charging is performed after roasting is finished; and 4) after the tundish vehicle, the hanging mechanism and the flow distribution device reach a casting position, the hanging mechanism hangs the flow distribution device to descend together, and places the flow distribution device on a bracket of the flow distribution device of the roasting pit, and then the hanging mechanism is separated from the flow distribution device for molten steel to inject. By the method, the time of strip continuous casting hot charging process can be effectively reduced, so that temperature drop of the flow distribution device in the process of hot charging is reduced, the problem that cold steel is easy to form when the high-temperature molten steel is contacted with the flow distribution device can be effectively avoided, and the success rate of strip continuous casting pouring is improved; the method is convenient to operate and the hot charging step is convenient to implement at the same time; and a heating furnace can also be saved and field resources are greatly saved.
