The invention discloses an agglomeration method for iron containing dust slime of iron and steel plants; according to the method, the iron containing dust slime is shunted independently, is briquetted, is mixed with other iron ore powder, flux and coke powder, and then is sintered on the basis of the traditional technology. The agglomeration method comprises the following detailed steps of: 1), firstly, mixing the iron containing dust slime with composite binder, mixing uniformly, briquetting, so as to obtain dust slime briquette; 2), mixing the dust slime briquette with other iron ore powder, flux and coke powder, pelletizing, so as to obtain sintered mixture material; and 3), distributing the sintered mixture material by adopting the existing sintering method, igniting, sintering, cooling, granulating, finally the finished product of sintered ore is obtained. Compared with the traditional method of directly returning, sintering and mixing the dust slime, by adopting the agglomeration method, the ratio of the iron containing dust slime in the mixture material is greatly improved, and in addition, the sintered product quality index is improved. By adopting the agglomeration method, the problem on large-scale use of the iron containing dust slime of iron and steel plants is effectively solved, and the agglomeration method is beneficial for industrial production.

The invention provides an electronic video game apparatus which includes a display for displaying a video depiction of a first card game on the display. Each card in the first card game has a card suit, a card value and a card color. At least one of these cards has an additional symbol which depicts at least one outcome of an independent game of chance (e.g. roulette, craps, slot machine, etc.), and a wagering mechanism enabling a wager to be placed on an outcome which is dependent on at least the additional symbol.

The invention discloses a method for microwave sintering of porous ceramsites by adopting medical waste incineration fly ash. The method comprises the following steps: (1) fully mixing the medical waste incineration fly ash with an auxiliary material, adding a small amount of water into the mixture, and carrying out granulation molding by a molding machine; (2) carrying out granulation molding, drying to obtain a particle raw material, filling the periphery of the particle raw material with a microwave coupling agent powder; and (3) carrying out microwave sintering of the particle raw material filled with the powder, and after sintering, cooling to the room temperature to obtain the porous ceramsites. The method can utilize a 'hot spot' effect of fly ash high-content active carbon in a microwave field to instantly completely decompose dioxins in the fly ash, at the same time, allows most heavy metals to be wrapped and cured in grids of the sintered product, and rapidly sinters the fly ash into the porous ceramsites; and the ceramsites can be used for building aggregates or wastewater filter materials, achieves further resource utilization while achieving harmlessness treatment of the medical waste incineration fly ash, and achieves many things at one stroke.

The embodiment of the invention discloses an exercise recommendation method and device, equipment and a storage medium, and relates to the technical field of network teaching. The method comprises thefollowing steps: receiving an exercise recommendation operation in a teaching video playing process; in response to the exercise recommendation operation, obtaining a corresponding search keyword according to playing data in the teaching video, the playing data including image data and / or audio data; searching in an exercise library according to the search keyword; and obtaining an exercise search result, and recommending the exercise search result to the user. By adopting the scheme, the technical problem that students cannot perform consolidation practice in the teaching process in the prior art can be solved.

The invention discloses a rice seedling machine seedling planting diaphragm and a manufacture method of the rice seedling machine seedling planting diaphragm. By aiming at the problems that the seedling root winding effect in the rice seedling machine seedling planting is poor, the seedlings can easily get scattered, and the operation is complicated, the invention provides the rice seedling machine seedling planting hemp-base diaphragm, which consists of a hemp fiber diaphragm substrate and rice seeds fixedly carried on the substrate. The hemp fiber raw materials are subjected to loosening, scattering and mechanical stretching to form a net, then, biodegradable bonding agents are adopted for bonding, baking is carried out, the hemp fiber diaphragm substrate is formed, and next, the rice seeds are uniformly scattered and pasted on the hemp fiber diaphragm substrate through the biodegradable bonding agents. When the rice seedling machine seedling planting hemp-base diaphragm provided by the invention is adopted, the seedling culture operation can be greatly simplified, farmers can realize the seedling culture without seeding, in addition, the seedling root system winding effect can be obviously promoted, the winding force is improved, seedlings conforming to the machine seeding requirements are formed, meanwhile, because the seedling quality is improved, the green returning speed of the seedlings after the machine seedling planting is high, the tillering effect is good, the rice yield is obviously improved, and good economic benefits are realized.

The invention relates to the technique of prevention of geological hazards, in particular to a debris flow prevention technique. The invention discloses a debris flow multi-stage dissipative blockingstructure, thus damage action of a debris flow can be lowered, and the disaster loss is relieved. According to the debris flow multi-stage dissipative blocking structure, from flowing area of the debris flow to the accumulation area, the debris flow multi-stage dissipative blocking structure is arranged in a step-by-step mode along debris flow channels from the upstream to downstream, and at leastincludes a flexible blocking net, a pile-carrying-type grid wall and a permeable buttress-type gravity dam. According to the debris flow multi-stage dissipative blocking structure, according to different geological conditions, types of the debris flows and the like, the matching structure of the flexible blocking net 2, the pile-carrying-type grid wall 3 and the permeable buttress-type gravity bam is reasonably selected, benefits of the investment in engineering construction can be given full play to the maximum extent, and cost benefit optimization is achieved. The debris flow multi-stage dissipative blocking system is very suitable for prevention of the debris flow disasters.

Disclosed is a high-pressure water-rich goaf grouting reinforcement method. Through the high-pressure water-rich goaf grouting reinforcement method, many defects of existing goaf grouting reinforcement methods are overcome, so that high-pressure water-rich goaf grouting reinforcement construction is feasible and fast, and the construction cost is saved. According to the high-pressure water-rich goaf grouting reinforcement method, artificial explosion is used for forming goaf top plate caving zones, high-pressure grouting is adopted in the caving zones under the action of high-pressure water on the two sides for forming curtain reinforcement bodies, and the problem that curtains are difficult to be formed by grouting liquid in a high-pressure water-rich goaf is solved. Grouting reinforcement is started from the periphery to the inside of a goaf reinforcement area, the pressure influence of high-pressure water on the periphery of the goaf reinforcement area and non-section supplement of a water source can be reduced gradually, grouting holes are used for water pumping and drainage so that the pressure of the high-pressure water in the goaf can be reduced, thus the condition that each grouting hole adopts high pressure grouting can be avoided, meanwhile, deposition and solidification of the grouting liquid are facilitated, accordingly, the construction time is saved, and the construction cost is reduced.
