The present invention relates to the field of bacterial agent amplification technology, in particular to a bacterial agent amplification and automatic delivery device for sewage treatment, comprising an amplification tank and a cover body, and also comprising an illumination component, wherein the illumination component comprises an annular seat, a plurality of lamp holders mounted on the annular seat, a rotation adjustment unit for driving the annular seat to rotate, and a height adjustment unit for adjusting the height of the annular seat, so as to adjust the distance between the rotating lamp holder and the liquid surface, and after adjusting the distance, the annular seat is rotated to drive the lamp holder to move in a circular trajectory; the present invention synchronously adjusts the heights of the plurality of lamp holders, so that a mixed solution of solid microbial agent and water is close to a light source, and in the process of culturing and amplification, the annular seat is continuously driven to rotate by the rotation adjustment unit, thereby driving the lamp holder to move in a circular trajectory, so as to achieve uniform irradiation of the mixed solution of solid microbial agent and water, which ensures the stability of the light source on the one hand, and is conducive to uniform illumination and improving amplification efficiency on the other hand.

This invention discloses a method for predicting the drum strength and RDI of sintered ore based on the characteristics of adhering powder in ore blending. The method includes: obtaining the particle size distribution and main chemical composition information of adhering powder under several ore blending conditions during actual sintering production; obtaining the actual measured values ​​of the drum strength and RDI+3.15 of sintered ore under several ore blending conditions during sintering production; constructing a numerical simulation model of the sintered ore temperature field to obtain the temperature level corresponding to the ore blending during sintering; using thermodynamic analysis methods to obtain the amount of liquid phase generated, liquid phase viscosity, and Fe2O3 / CaO ratio under the corresponding ore blending and sintering temperature conditions; and then constructing a prediction model for the drum strength and RDI of sintered ore. This invention can optimize and adjust the ore blending structure in a timely manner based on the prediction results, maintaining a reasonable drum strength and RDI of sintered ore, forming a rapid response for optimized ore blending from the source and mechanism, and can better support blast furnace production.

The four-way shuttle vehicle comprises a vehicle frame main body, and a first wheel set is movably arranged on the side wall of the vehicle frame main body; the jacking plate is movably arranged on the frame main body, and a second wheel set is movably arranged on the side wall of the jacking plate; the at least two first control rods are rotationally arranged on the frame main body; at least two reversing mechanisms are arranged on the same first control rod and are respectively connected to the jacking plate and the frame main body; the first control rod rotates to drive the two reversing mechanisms to get away from or get close to each other and drive the frame body to get away from or get close to the jacking plate, so that the second wheel set or the first wheel set makes contact with the ground, and the movement direction of the four-way shuttle vehicle is changed. Compared with similar products, the device is simpler, simple in transmission, stable in structure and higher in efficiency.

The utility model provides a hub of an anti-puncturing tire, and belongs to the technical field of wheel production. Comprising a main body, a spoked wheel is fixedly connected to the interior of one side of the main body, the molded surface of the main body comprises a head at one end, a middle section in the middle and a tail at the other end, the head, the middle section and the tail are of an integrated structure, and a plurality of protruding ribs are fixedly connected to the inner wall of the main body. By arranging the head part, the middle section and the tail part, the step design of the head part increases the structural strength; the thickness of the middle section is reduced, the material distribution is optimized, and the anti-pricking tire is conveniently and quickly disassembled and assembled through the connection of the b angle between the head part and the middle section; through the arc transition design of the b angle of the tail part and the middle section, the structural strength is enhanced, the material redundancy is reduced, the stability of the device is improved, through the integrated design of the head part, the middle section and the tail part, the structure of the whole hub is more compact, the material consumption of the structure is reduced, and the material utilization rate is increased to 90% or above.
