5results about How to "Reduce wind speed" patented technology

The application discloses a kind of for tantalum niobium tailings in tin metal recovery's synergistic treatment system, specifically related to metallurgical solid waste resource utilization technical field, acoustic-electricity perception pre-agglomeration module exports pre-agglomeration probability index according to pre-agglomeration threshold value;Heat resistance chromatography module exports the temperature field and fluidized void fraction distribution of suspected agglomeration area;Inhibiting ingredient self-adapting module calculates inhibitor addition rate according to distribution;Wind material decoupling adjustment module exports decoupled wind speed and feed rate set value according to addition rate and bed pressure drop;Chain negative feedback blocking module detects pressure drop deviation to generate feedback correction, superimposed to wind speed set value and reversely adjust feed rate set value, while used to update pre-agglomeration threshold value;The application realizes the online identification of agglomeration precursor, accurate danger area precision inhibiting and the closed-loop cooperation of wind material decoupling, inhibits the nonlinear deterioration of coking loss flow, makes tin recovery rate keep stable when tailings fluctuation, and reduces inhibitor consumption and manual intervention.

The utility model relates to the field of copper clad plate gluing and drying, especially to a copper clad plate gluing and drying device. It comprises a feeding roll, a material receiving roll and a drying box. A first gluing roller and a second gluing roller are horizontally arranged on one side below the feeding roll, and the first gluing roller and the second gluing roller extend into a gluing groove. The material receiving roll is arranged on one side above two limiting transmission rollers. Electronic glass fiber cloth is sequentially immersed in the gluing groove through the first gluing roller and the second gluing roller from the feeding roll. The feeding roll and the material receiving roll are driven to rotate by a motor. The device uses negative pressure to form an air duct for drying. The opening of the air outlet faces downward, and the arc-shaped air outlet guide surface on one side can make the air outlet larger, so that the air speed of the air duct is smaller. The air inlet groove is provided with multiple air inlets, and the shape of the air inlet groove is an arc that curves upward. Hot air that goes out of the air inlet groove will be guided to move obliquely upward. The multiple air inlets can not only prevent the hot air from being directly blown but also make the drying process more gentle.

The utility model belongs to the technical field of cyclone dust collectors, and particularly relates to a cut-off type wear-resistant conical cylinder structure of a cyclone dust collector, which comprises an upper conical cylinder body and a lower conical cylinder body which are coaxially arranged up and down, a ceramic wear-resistant layer is adhered to the inner wall of the lower cone cylinder, and the surface of the ceramic wear-resistant layer is smooth; the upper cone cylinder and the lower cone cylinder are connected through a second flange structure to form a detachable and separable complete cone cylinder structure, and the bottom of the lower cone cylinder is connected with a discharging valve through a first flange structure. According to the technical scheme, the problems that a traditional conical cylinder is prone to abrasion, troublesome to replace and difficult to maintain are solved, and practicability and economical efficiency are both achieved.

The utility model discloses a dustproof noise reduction automobile air channel relates to automobile parts technical field, and it is connected with the air inlet pipe head in the air inlet end of air channel pipe body, the inside installation of air inlet pipe head has first dust screen and second dust screen, the mesh diameter of second dust screen is less than the mesh diameter of first dust screen, the middle part of first dust screen and second dust screen is all set to concave hemispherical shape, the inner wall of air channel pipe body is provided with sound absorption bubble cotton layer, one side of sound absorption bubble cotton layer is set in wave type away from the inner wall of air channel pipe body, the inner wall of air channel pipe body is fixed with a plurality of convex post, and the convex post is nested in sound absorption bubble cotton layer. The utility model can effectively intercept the impurity in air, and the air inlet pipe head is convenient to disassemble and clean, and the setting of sound absorption bubble cotton layer in air channel pipe body can effectively disperse the air direction, reduce the wind speed, reduce the sound frequency, thereby reduce the pneumatic noise in air channel pipe body.
