Provided is a powder stirring tank with a simple structure and raising the stirring efficiency. The powder stirring tank comprises a stirring tank, a stirring shaft and stirring blades. The stirring shaft is arranged in the center of the stirring tank vertically. The stirring blades are arranged at the lower end of the stirring shaft. Elastic projections are distributed on the inner wall uniformly. A heavy bob is movably arranged on the surface of the stirring tank. The stirring shaft has a hollow holding cavity. A plurality of telescopic elastomers are distributed on the surface of the stirring shaft uniformly. Through holes communicated with the elastomers are arranged in the side wall of the stirring shaft. The upper end of the stirring shaft is communicated with a gas source. The stirring quality is raised greatly, powder is mixed uniformly after stirring, the quality is fine, the structure is simple and usage is convenient.

The invention discloses a porous spherical carbon adsorption material with blood compatibility, which belongs to the technical field of material preparation. The porous spherical carbon adsorption material is a composite carbon sphere; the composite carbon sphere is composed of single-layer or multi-layer hollow carbon The microspheres are self-assembled under the action of the binder; the multi-level pore structure is as follows: the first level is the micron-scale radial pore channel from the surface of the composite carbon sphere to the interior, and the second level is the internal connection of the large pore channels of the composite carbon sphere The submicron pore structure between them, the pore walls of the primary and secondary pore structures are composed of hollow carbon microspheres and binders, and the third level is the nanoscale pore structure of the hollow carbon microspheres that make up the composite carbon spheres. The porous spherical carbon adsorption material described in this application has good adsorption properties for various adsorbents, especially for medium and large molecular toxins, and has good blood compatibility. , Water treatment and other adsorption fields have a good application prospect.

A stator structure and a manufacturing method thereof, in which wires are respectively wound in the wire slots formed by the outer and inner slots of each H-shaped tooth to form a winding, and one winding coil is wound on one H-shaped tooth. When the winding is energized, the spatial position of an H-shaped tooth forms two N / S magnetic poles tangential to the stator circumference; that is, when there are 4 teeth (H-shaped teeth) in the yoke, 8 magnetic poles can be generated, which can The torque and speed equivalent to the traditional 8-tooth stator structure are obtained, and the material consumption is small, and the size is nearly doubled compared with the traditional structure; compared with the distributed winding stator, slot wedges are not required.

The invention belongs to the technical field of polymer materials, in particular to a refractory silica gel material and a preparation method thereof. The invention combines sodium bicarbonate and gelatin, and dissolves aluminum sulfate in the agar layer of the outer layer to prepare The multi-layer structure, and then make the outer part of the coated functional thread meet the temperature rise, with the transfer of temperature, the inner layer of the functional fiber is first dissolved, so that the gelatin is mixed with sodium bicarbonate and calcium hydroxide, and with The continuous rise of the temperature makes the agar dissolve slowly. During the process of the agar slowly dissolving, the aluminum sulfate solution and the sodium bicarbonate solution in the agar layer undergo a double hydrolysis reaction, releasing a large amount of carbon dioxide, and the carbon dioxide causes the calcium hydroxide inside to condense as Calcium carbonate is adsorbed on the surface of the fiber filaments, thereby enhancing the hardness of the fiber filaments and playing the role of skeleton support. At the same time, the impact of carbon dioxide has a hindering effect on the combustion of the flame, so that the obtained silica gel material has better flame retardant and fire resistance. sex.
