Drum-type medicinal material cleaning equipment with automatic discharging function

The drum-type medicinal material cleaning equipment with the automatic discharging function comprises a horizontally-arranged supporting box body, a horizontally-arranged drum is arranged in the supporting box body, and the outer wall of the drum is rotationally connected with the inner wall of the supporting box body through at least eight rolling structures. One end of a feeding port of the roller is located outside one end of the supporting box body, one end of a discharging port of the roller is flush with the other end of the supporting box body, the inner wall of the roller is connected with a continuous spiral feeding piece, the two ends of the spiral feeding piece are connected with the inner walls of the two ends of the roller respectively, and a plurality of through holes are evenly formed in the roller. The top of the outer wall of the supporting box body is connected with a driving mechanism for driving the roller to rotate, the top of the inner wall of the supporting box body is connected with a spraying mechanism for cleaning medicinal materials, and the spraying mechanism is located above the roller, so that the problem that the medicinal materials are difficult to fish out from a container after being cleaned at present is solved; the problem that impurities are easily attached to the surfaces of the medicinal materials again after the medicinal materials are cleaned is also solved.

A fluidized bed boiler for treating papermaking sludge

This application relates to the papermaking field, and in particular to a fluidized bed boiler for treating papermaking sludge. Addressing the shortcomings of existing technologies that cannot rapidly press the sludge, resulting in difficulty in separating the moisture contained in the sludge, the following solution is proposed: a drainage tank; a support plate fixedly connected to one side of the drainage tank, with two baffles fixedly connected to the top of the support plate; a discharge port located on one side of the drainage tank, with a boiler fixedly connected to one side of the discharge port; six support columns fixedly connected to the bottom of the drainage tank, the support plate, and the boiler, with an adsorption tank fixedly connected to the top of the boiler; a flue gas outlet located on the top of the adsorption tank, with a first housing fixedly connected to one side of the drainage tank; and a transmission assembly fixedly connected to one side of the first housing. This application enables rapid pressing of the sludge, facilitating the separation of moisture from the sludge.

Preparation method of foam metal

The invention discloses a preparation method of foam metal, and belongs to the technical field of porous metal preparation. The method comprises the following steps: forming a single-layer foam half-hole structure by a metal sheet through a mold pressing process, and carrying out closed hole combination after surface treatment and functional material filling to form a single-layer foam structure; and the single-layer foam structures are stacked and combined in a three-dimensional space, and the foam metal is obtained. Metal sheets made of different materials are selected according to product purposes, and different types of molds are selected for die forming according to the shapes of the air holes and the materials of the metal sheets; different surface treatment processes or functional materials are selected for filling according to product purposes, and the single-layer foam structures are combined in a welding mode, a riveting mode, a gluing mode, a high-temperature sintering mode and the like. The size and shape of the air holes are effectively controlled through mold design, the process period is greatly shortened, functional material filling can be achieved in the air holes, and a single-layer foam half-hole structure can endow the foam metal with a new function through surface treatment.
