The invention relates to a breeding technology of fly maggots and aims to provide a method for breeding fly maggots in two steps under conditions of normal temperature and low temperature. The method is characterized by adding an enhanced treatment stage before the common breeding treatment method and retaining high environment temperature of the former growth period in a manner of increasing the breeding density of larvae of fly maggots, and increasing independent room temperature or providing coverage for the larvae. The enhanced process can be used for improving the features and the nutritional characteristics of the breeding materials; the growth condition of the larvae of fly maggots can be improved; the growth of the fly maggots can be improved; the indoor enhanced process can be used for improving the growth environment of the larvae of fly maggots by increasing the temperature; the relative temperature-increasing cost is low; the larvae of fly maggots after the enhanced treatment are large in larva instar and size and high in resistance to low temperature; the survival rate of the larvae of fly maggots under the condition of the relative low temperature is higher than that of the larvae which are just hatched in 24 hours. The method can be used for increasing the utilization rate of the land; the biomass waste fly maggots such as excrements of livestock can be annually treated; the method has great effects on enterprise benefit and development and quick and effective treatment on the excrements of livestock.

The invention discloses a hammer type crusher internally provided with a feeding fan and a rotary screen, which comprises a shell, a driving device as well as rotary screen assembly and a rotor assembly that are arranged inside the shell, wherein the rotary screen assembly comprises a fan and a filter screen; the rotor assembly comprises a hammer carrier plate and a hammer piece; the driving device drives the rotary screen assembly and the rotor assembly to rotate along the opposite directions at the same time; the fan can be used for throwing the material to the end of the hammer piece alongthe direction of 360 degrees, so that the material can be completely crushed by the hammer piece; meanwhile, the rotary screen assembly and the rotor assembly rotate along the opposite directions, sothat a material circulation layer can be prevented from being formed, and the problems of material blockage, excessive crushing, uneven granularity, high material temperature, high consumption and energy consumption and the like can be avoided; and the filter screen rotating at the wrap angle of 360 degrees is beneficial to discharging, so that circumferential 360-degree feeding and 360-discharging can be realized, and the problem that a screen of the traditional crusher is fixed, so that the feeding direction is limited can be solved. The hammer type crusher has the advantages of high efficiency, energy conservation, environmental protection, good quality of finished goods and the like, and can be applied to vertical and horizontal hammer type crushers, thus having wide application scope.

The invention discloses a method for reducing water of sintered mixture, which belongs to the technical field of sintering process in the metallurgical industry. The main technical problem to be solved by the present invention is to reduce the moisture in the sintering mixture and thereby reduce the energy consumption of the sintering process. The basic technical solution of the present invention is: a water-reducing method for sintered mixture, which includes the process of blowing the sintered mixture in the process of falling through the nozzle and using wind force to make it particle size segregated, characterized in that: the sintered mixture The moisture content is reduced by at least 3.6%. The invention is not only suitable for newly designed sintering machines, but also suitable for the transformation of existing sintering machines.

The invention discloses a method for preparing high-nickel molten iron from low-grade laterite-nickel ore by using chain grate machine preheating and electric furnace smelting separation. The method comprises the following steps that S1, drying pretreatment and crushing are carried out on the laterite-nickel ore to obtain laterite-nickel ore powder; S2, the laterite-nickel ore powder is uniformlymixed with a fusing agent to obtain a uniform mixture, and pelletizing is carried out to obtain green balls; S3, the green balls are fed into a chain grate machine for drying, preheating and roastingto obtain preheated pellets; and S4, the preheated pellets are mixed with a reducing agent, and then are fed into an electric furnace for smelting separation to obtain high-nickel molten iron and furnace slag. According to the production method, the electric furnace burden which is high in strength, uniform in particle size and excellent in quality is prepared, and the high-temperature hot preheated pellets are directly fed into the electric furnace to be subjected to reduction and smelting separation, so that the heat required for re-heating to reach the smelting separation temperature is saved, then the electricity consumption of the electric furnace is reduced, and meanwhile, the metal recovery rate is improved.

A device for preheating to-be-sintered raw materials with steam and sludge belongs to the technical field of sintered ore. The device comprises a primary concentration basin, a secondary concentration basin, a filter screen, a steam pipeline, a lifting platform, a sludge pump, a mud stirring paddle and a through hole, wherein the primary concentration basin and the secondary concentration basin communicate with each other through the bottom through hole; the filter screen is located at the upper part of the primary concentration basin; the steam pipeline is located at the four corners of the secondary concentration basin; the lifting platform is located above the secondary concentration basin; and the sludge pump and the mud stirring paddle are mounted in the middle of the lifting platform. The device has the advantages of simple structure, low site requirement and easiness in implementation. The sludge concentration of equipment with no steam pipeline is about 20%-25% in general, and the concentration is increased to 35%-38% after the steam pipeline is arranged on the equipment.

The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a cultivation material formula and a production method for industrial production of Flammulina velutipes. The cultivation material of Flammulina velutipes consists of the following raw materials in percentage by weight: 42% to 50% of Artemisia annua, 28% to 32% of cottonseed hulls, 12% to 16% of bran, 5% to 10% of soybean powder, and 0.5% of calcium carbonate. %~2.0%, lime 1.0%~3.0%, magnesium sulfate 0.2%~0.5%. The cultivation material uses Artemisia persicae as the main material, which not only solves the cost problem of raw materials for the production of Flammulina velutipes, improves the cultivation efficiency, but also realizes the effective utilization of Artemisia persicae weeds, and reduces the damage and pollution to the environment. The production method of Flammulina velutipes realizes the purpose of high-efficiency production under the factory mode.

The invention discloses preserved beancurd containing a functional factor, which comprises components of soybean and edible (medicinal) fungi. A preparation method for the preserved beancurd containing the functional factor comprises the following steps: soybean, edulcoration, soaking, soybean grinding, filtering separation, soybean milk, soybean milk cooking, soybean milk curdling, blanking, block division, pehtze preparation fermentation, salted pehtze, filling, ripening, and a finished product. During soybean milk curdling, a mixed solution of an aqueous solution of edible (medicinal) fungiultra-fine powder and the soybean milk is added, and the soybean milk curdling is realized by the following steps: removing roots of the edible (functional) fungi and carrying out edulcoration on theedible (medicinal) fungi; carrying out ultrafine grinding on the edible (medicinal) fungi after drying or insolating; adding water to dissolve, wherein the ratio of the edible (medicinal) fungi ultra-fine powder to the water is 1:4; adding the soybean milk at 100 DEG C with the same quantity as the aqueous solution of the edible (medicinal) fungi ultra-fine powder into the mixture to dilute afterthe mixture is stirred fully and evenly; and during filling, the aqueous solution of the edible (medicinal) fungi ultra-fine powder is added. The preserved beancurd is rich in functional factor and multiple nutrients and has the advantages of health care function, tasty mouthfeel and simple processing.
