The invention discloses a wick structure for a vapor chamber. The wick structure comprises multiple condensing zones radiating from center to outside, each condensing zone is formed by a multistage channel structure formed by branching step-by-step from a central beginning channel to outside, each stage comprises at least two narrow channels, the number of the narrow channels in each stage increases from center to outside stage-by-stage, the narrow channels in each stage and the narrow channels among stages are mutually communicated to enable each condensing zone to form a latticed channel structure, the width of the narrow channels of a next stage is smaller than that of the narrow channels of a front stage, and the length of the narrow channels of a next stage is smaller than or equal to that of the narrow channels of a front stage. The wick structure for the vapor chamber has the advantages of high capillary attraction, low flow resistance and high temperature evenness and heat radiating efficiency.

The invention is suitable for heating and baking bulk materials such as ferroalloy for steelmaking, etc., and relates to a heating furnace with double furnace bodies, including an outer furnace body, an inner furnace body and a furnace cover. The outer furnace body is a steel container with a heat-insulating layer. There is a platform inside, a sealing ring on the upper part, and ventilation holes on the upper and lower sides of the platform; the bottom of the inner furnace body has a grate made of heat-resistant steel. There are hoisting holes or hoisting trunnions on the upper part of the plate, and ferroalloy materials are contained inside; the inner furnace body sits on the bearing platform of the outer furnace body, and the contact surface between the inner furnace body and the bearing platform of the outer furnace body is the sealing surface; the furnace cover sits Placed on the sealing ring on the outer furnace body; when the furnace cover is removed, the inner furnace body can be hoisted into or out of the outer furnace body. The invention evenly heats the ferroalloy material, has simple structure, high reliability, no burner in the furnace, no local high temperature, does not burn the furnace wall, high thermal efficiency, is matched with a general flue gas furnace, has reliable performance and long service life.

The invention relates to a bright molybdenum concentrate self-heating type rotational flow roasting technology and equipment. A rotational flow roasting furnace provided with a furnace body heat exchanging device is utilized to roast bright molybdenum concentrate so as to produce industrial molybdenum oxide. The heat emitted by a roasting reaction of the bright molybdenum concentrate is utilized to preheat air entering from an interlayer heat exchanging device of a lower furnace body in the roasting process, the preheated air is supplied into the rotational flow roasting furnace from the furnace bottom, a rotational flow wind distributing device makes the bright molybdenum concentrate be subjected to a roasting reaction under a rotational eddy state, a material coming out from the rotational flow roasting furnace enters an upper interlayer heat exchanging device of the rotational flow roasting furnace along with roasting eddy under the effect of negative pressure, a desulfurization reaction is completed in the interlayer heat exchanging device in the rotational advancing process, and a reacted gas-solid mixture enters a gas-solid separation discharging device to be subjected to gas-solid separation so that a solid roasted product and roasted smoke can be separated. The roasted smoke is sent to a SO2 recycling processing system under a draft effect of an induced draft fan afterentering a heat exchanger to exchange heat with the air, and the air after being subjected to heat exchanging is sent to a flash evaporation drying machine to dry the bright molybdenum concentrate.

The invention discloses a composite bottom pot body and a manufacturing method thereof. The composite bottom pot body (100) comprises a pot bottom wall (1) and a composite bottom sheet (3) arranged at the bottom of the pot bottom wall. The pot bottom wall and the composite bottom sheet A compound bottom cavity (5) is formed therebetween, the pot bottom wall and the compound bottom sheet are fixedly connected by a connecting piece (2), and the compound bottom cavity is also filled with a sintered compound bottom cavity filling material (4). The manufacturing method includes connecting the double bottom sheet at the bottom of the bottom wall of the pot through a connecting piece; welding and sealing the peripheral edge (31) of the double bottom sheet and the outer peripheral wall of the pot body; filling the compound bottom cavity between the reciprocating bottom sheet and the pot body. The bottom cavity filling material; finally, the pot body with the double bottom sheet and the double bottom cavity filling material is heated. The cookware of the invention can thicken the bottom of the pan, improve the heat storage performance and thermal conductivity of the bottom of the pan, improve the temperature uniformity of the bottom of the pan, reduce the generation of oil fume, and improve the product quality and user experience. The manufacturing method is simple, practical and low in cost, and can be used in mass production with high efficiency.
