The invention discloses a coking blending coal blended with recycled materials and a coking coal blending method. The weight ratio of the components is: fat coal (16-2N)%, high-sulfur coal 19-21%, 1 / 3 coking coal 4~6%, coking coal 39~41%, lean coal (7-N)%, gas coal (12+2N)%, recycled material N%, said N≤5; the content of β resin in said recycled material is 21~24wt%. This blended coal uses β resin with caking effect and combines it with coking coal blending technology to replace part of fat coal and add it to coking coal to produce coke, which can not only expand coking coal resources, but also reduce high-priced fat coal blending. Ratio, reduce coal blending cost. This coal blending method widens the plastic temperature range of coking coal, so that various coal types can better connect and overlap each other, improve the coking performance of the coking process, and promote the anisotropy generation technology; in ensuring the quality of coke to meet the requirements of large-scale Under the condition of blast furnace coke demand, the proportion of lean and weak coal with weak cohesion can be maximized in coking coal blending, so as to greatly reduce the cost of coal blending.

The present invention relates to a comprehensive recovery process for a rare earth and strontium intergrowth multi-metal ore. The mineral mainly comprises rare earth fluoro-carbonate and at least one selected from a sulfate of the strontium, a carbonate of the strontium or a strontium oxide. According to the present invention, at least one method selected from gravity separation, magnetic separation and flotation separation is adopted to carry out concurrent screening for the rare earth and the strontium in the rare earth and strontium intergrowth multi-metal ore to obtain the bulk concentrate containing the rare earth and the strontium; then the bulk concentrate is subjected to oxidizing roasting for 1-8 hours at a temperature of 350-700 DEG C in air atmosphere or oxygen atmosphere; the resulting calcine is subjected to leaching for 1.0-5.0 hours by a sulfuric acid solution with the hydrogen ion concentration of 0.5-12.0 mol / L, wherein the leaching temperature is 20-100 DEG C, the leaching liquid-solid ratio (by weight) is 1-5:1. The comprehensive recovery process of the present invention has the following advantages that: the rare earth is almost entirely leached in the solution; the strontium sulfate (SrSO4) is remained in the residue; the strontium concentrate with the grade of about 70% is obtained, and can be sold directly or deep processed; with the comprehensive recovery process of the present invention, the multi-metal ore containing the rare earth and the strontium can be effectively separated.

The invention discloses an adjustable material splash-prevention cover plate. The adjustable material splash-prevention cover plate comprises a cover plate shell and an L-shaped mounting fixed plate;a cover plate comprises a fixed cover plate and a plurality of sliding cover plates; an upper L-shaped clamping groove I is formed in the top side edge of the fixed cover plate; upper L-shaped clamping grooves II are formed in the top side edges of the sliding cover plates; and clamping position grooves are formed in two ends of the upper clamping grooves II. The adjustable material splash-prevention cover plate is novel in structure, is capable of realizing the storage and unfolding of cover plates, and is convenient to mount and dismount so as to facilitate the using of people; by utilizinga sliding chute, sliding, on the fixed cover plate, of the sliding cover plates is realized; by utilizing the clamping position grooves and clamping position through holes, clamping of clamping position rods is convenient, gaps between the cover plates during the clamping are decreased, so that zero-splash of materials is ensured; by utilizing the L-shaped clamping grooves II and lowe-shaped clamping grooves, the adjacent sliding cover plates can be mutually matched and clamped, so as to ensure that no gaps exist between the sliding cover plates; and by utilizing threaded holes and threaded rods, the cover plates can be fixed on sliding rails when being unfolded, so that the cover plates can be conveniently mounted and fixed.

The invention provides an air circuit breaker assembling machine. A workbench, a drive motor, a fixing table, an executing device, fixing devices and an auxiliary device are included. The upper end ofthe workbench is provided with the drive motor through a motor base. An output shaft of the drive motor is connected with the fixing table through a flange. The executing device is arranged at the middle portion of the fixing table, and the fixing devices are evenly arranged at the upper end of the fixing table around the circumference direction of the fixing table in a sliding fit manner. The auxiliary device is arranged on the workbench and located above the fixing devices. The air circuit breaker assembling machine can solve the problems that in the process that an operation handle of a circuit breaker is manually pushed up and then is sleeved with a ceramic shell, the manual operation efficiency is low, inner components in the incompletely-assembled circuit breaker are not completelyfixed, and disengaging of the inner components is likely to be caused by manual operation handle carrying; and meanwhile, the manual installing efficiency is low, and the work efficiency of a production line is influenced.
