The invention relates to the technical field of ocean engineering deep-sea mining equipment, in particular to a multi-metal nodule desliming device suitable for deep-sea mining, which consists of a mineral aggregate input connecting flange, a mineral aggregate input transition cabin, a mineral aggregate enrichment cabin, a waste discharge cabin, a desliming screen, a screen fixing frame, a screen fixing screw and a waste discharge guide plate. The mineral aggregate input connecting flange is located at the front end of the multi-metal nodule desliming device and used for being connected with the multi-metal nodule collecting and conveying device, the mineral aggregate input transition cabin is tightly connected with the mineral aggregate input connecting flange, and a square opening is formed in the rear end of the mineral aggregate input transition cabin. The shape of the front end of the mineral aggregate input transition cabin is the same as that of the mineral aggregate input connecting flange.

The utility model discloses a waterproof breathable film component, which comprises a blue film layer, a waterproof breathable film layer and a pressure-sensitive adhesive layer, the blue film layer comprises a body and a handle part which are connected, and the body and the handle part are coplanar; the outer contour size of the waterproof breathable film layer is the same as that of the body, and the waterproof breathable film layer and the blue film layer are fixed in an electrostatic adsorption mode. The whole pressure-sensitive adhesive layer is in an annular frame shape, the outer contour size of the pressure-sensitive adhesive layer is the same as that of the waterproof breathable film layer, and the pressure-sensitive adhesive layer is connected with the side, away from the blue film layer, of the waterproof breathable film layer; the length of the body is 8.18 + / -0.08 mm, the width of the body is 2.08 + / -0.08 mm, and the weight of the waterproof breathable film layer is 5 + / -0.1 g. According to the waterproof breathable film assembly, the size and the weight of the blue film layer are reasonably set, and when a worker uncovers the blue film layer, the blue film layer cannot damage the waterproof breathable film layer and cannot enable the waterproof breathable film layer and the pressure-sensitive adhesive layer to be separated.

The invention discloses a household air conditioner interaction ability evaluation method, system and device and a medium. The method comprises the steps that evaluation data matrixes of indexes of a to-be-evaluated air conditioner of multiple evaluation objects and technical parameters of the to-be-evaluated air conditioner are obtained; calculating by utilizing a variable coefficient correction method based on the evaluation data matrix to obtain the subjective weight of each index; calculating by using an entropy weight method based on the evaluation data matrix to obtain an objective weight of each index; calculating by utilizing a game theory weighting method based on the subjective weight and the objective weight to obtain a comprehensive weight of each index; evaluating based on the comprehensive weight of each index and the technical parameters of the to-be-evaluated air conditioner to obtain an evaluation result; the subjective weight is determined more accurately through the variable coefficient correction method; the objective weight is determined through the entropy weight method, so that the weighting is more objective, and the credibility is higher; the subjective weight and the objective weight are considered through game theory combination weighting, and a more reasonable comprehensive weight is obtained; and the interaction capability of different types of household air conditioners can be evaluated through the comprehensive weight.

The utility model belongs to the technical field of forging and pressing processing, and particularly relates to an oxygen lance nozzle forging and pressing die which comprises a lower die fixing frame, the lower die fixing frame is connected with an upper die fixing plate in a sliding mode through a positioning assembly, an upper die is fixedly connected below the upper die fixing plate, a lower die assembly is fixedly connected above the lower die fixing frame, and the lower die assembly comprises a lower die fixing base. The lower die fixing base is fixedly connected with the lower die fixing frame, a lower die block is fixedly connected into the lower die fixing base, a center block is arranged in the center of the lower die block, a plurality of oxygen column blocks are arranged between the lower die block and the center block, and the center block can move up and down to drive the oxygen column blocks to be away from or close to the lower die block. The oxygen lance nozzle demoulding device has the advantages that the conception is ingenious, the structure is reasonable, the oxygen lance nozzle which is light in weight, cannot cause overweight of products and does not need to be subjected to subsequent processing to remove redundant materials can be produced, and the demoulding problem of the oxygen lance nozzle is ingeniously solved.
