This utility model specifically relates to a drying device for rice processing, comprising an inner drying tank and a heating outer tank. A drying mechanism is located between the inner and outer tanks, comprising a stirring rod, heating wire, temperature monitor, and drive motor. A feeding preheating mechanism is located at the top of the heating outer tank, and its interior includes a feeding assembly and a heat-conducting pipe. The inner and outer tanks are detachably connected via a split-type disassembly mechanism, which consists of a fixing ring, a slot, a locking block, fastening bolts, and threaded holes. A screening mechanism is located at the bottom of the inner drying tank. This utility model not only reduces the humidity of rice entering the inner drying tank, improving the working efficiency and quality of the dried rice, but also enhances the convenience of maintenance.

The invention provides a mugwort charcoal hot patch prepared by adopting a low-temperature slow baking process, and relates to the technical field of heating physiotherapy products. The mugwort charcoal hot patch prepared through the low-temperature slow baking process comprises a breathable inner layer, a mugwort charcoal functional layer, a heating layer and a protective outer layer, the breathable inner layer is made of full-bio-based degradable non-woven fabric, the mugwort charcoal functional layer is close to the breathable inner layer, the core component is mugwort charcoal subjected to composite modification treatment through the low-temperature slow baking process, and the protective outer layer is made of non-woven fabric. The mugwort charcoal functional layer can continuously and stably release active ingredients under the heat action of the heating layer. The mugwort charcoal is prepared by combining a low-temperature slow baking process with composite modification treatment, active ingredients in mugwort can be fully reserved, the mugwort charcoal and the mugwort leaf extract are synergistic at a heating temperature, trace ingredients with soothing, blood activating and aromatic effects can be continuously and stably released, far infrared rays radiated by the infrared emission ceramic powder are combined with thermal therapy, and the health care effect is achieved. And the physiotherapy effect is obviously improved.

The utility model discloses energy-saving aluminum ore calcining equipment, and relates to the technical field of calcining equipment, the energy-saving aluminum ore calcining equipment comprises a gas collector, a rotary kiln, a discharge bin and a preheater, the preheater comprises a shell and a plurality of partition plates; a feed port and an exhaust port are formed in the top of the shell, and the exhaust port is connected with an inlet of the gas collector through an exhaust pipeline; a discharge port is formed in the bottom of the shell and is connected with an inlet of the discharge bin; an air inlet is formed in the bottom of the shell and connected with the rotary kiln through an air inlet pipeline. The multiple partition plates are connected to the two opposite inner walls of the shell in a crossed mode, and the two opposite sides of the partition plates abut against the other two inner walls of the shell. According to the energy-saving aluminum ore calcining equipment, after high-temperature gas generated in the calcining process of the rotary kiln is introduced into the preheater, the high-temperature gas can circulate in the shell in a snakelike path, the circulating path of the high-temperature gas in the preheater is prolonged, the high-temperature gas makes full contact with uncalcined materials, and therefore the preheating time of the uncalcined materials is prolonged, and the energy-saving effect is achieved. The preheating effect is improved.

This invention discloses a waste aluminum recycling device, including a melting furnace and an electromagnetic stirrer disposed below the melting furnace. A frustum-shaped outer shell is inserted from above into the middle of the melting furnace. A conical auger body is disposed inside the frustum-shaped outer shell. A perforated cylinder is installed below the frustum-shaped outer shell. The portion of the frustum-shaped outer shell inside the melting furnace has densely packed exhaust holes. A buffer chamber is inserted above the melting furnace and is located outside the frustum-shaped outer shell. At least three heat recovery pipes are evenly installed between the buffer chamber and the feed hopper. This invention incorporates a perforated cylinder to ensure that waste aluminum can uniformly reach the interior of the molten aluminum in the vertical direction. Exhaust holes are provided on the lower side wall of the frustum-shaped outer shell to prevent gas from reaching the interior of the molten aluminum and causing air bubbles to remain inside the molten aluminum.
