The invention discloses a vacuum drying device. The vacuum drying device comprises a mounting cover, an inner cover and an extraction opening, a mounting space for accommodating a substrate is formed in the mounting cover, a plurality of uniformly distributed first air holes are formed in the mounting cover, the first air holes are communicated with the mounting space, and at least part of the first air holes are located above the substrate; the inner cover covers the mounting cover, the inner cover and the mounting cover are arranged in a spaced mode, a first cavity is formed between the inner cover and the mounting cover, the first cavity is communicated with the mounting space through the first air holes, and a plurality of second air holes which are evenly distributed are formed in the upper portion of the inner cover; an extraction opening is communicated with the second air hole and is positioned above the inner cover; and gas in the mounting space sequentially flows to the first gas hole, the first cavity, the second gas hole and the extraction opening. The upper air exhaust vacuum drying device is simple in structure and low in installation precision requirement.

The utility model discloses an oblique folding wave anti-blocking counter flow type cooling tower packing sheet with bonding points, and belongs to the technical field of cooling tower packing. The cooling structure comprises a group of transverse flow channel cooling structures and oblique flow channel cooling structures, the transverse flow channel cooling structure comprises a set of first protrusions, a vertical first channel is formed between every two adjacent first protrusions, and a set of first retention areas are arranged in each first channel. The inclined flow channel cooling structure comprises a group of second bulges, an inclined second channel is formed between the adjacent second bulges, and a group of second retention areas are arranged in the second channel; the first channels and the second channels are in one-to-one correspondence and staggered arrangement, and inclined flow guide planes are arranged between the first channels and the second channels. Based on the alternate structural design of the transverse flow channels and the inclined flow channels, the transverse flow channels can provide a larger contact area, so that cooling water can be in full contact with the surface of the filler, and the heat and mass transfer efficiency is improved; the introduction of the inclined flow channel provides flow paths in different directions for the water flow, so that the water flow can be more uniformly and stably distributed in the whole filler.

The utility model is suitable for the technical field of automobile brake, provides a kind of automobile brake cylinder body casting uses conical side face pouring type mould, including mould frame, the mould frame includes the horizontal setting fixed mould frame and movable mould frame, the fixed mould frame inside is close to movable mould frame one side and is provided with fixed mould, the movable mould frame inside is close to fixed mould frame one side and is provided with movable mould;The fixed mould is set to quadrangle structure, and its close movable mould one side is provided with fixed mould cooperation groove, the movable mould is set to quadrangle structure, and shape is adapted with fixed mould, and the movable mould top is close to fixed mould one side end and is provided with material handle shunt cone.This device solves the problem that the uneven flow rate of the metal liquid generated in the one-piece inner gate encounters collision and generates eddy current, which increases the internal stress of the metal liquid, ultimately affects the uniformity of the finished product, achieves pouring from the conical runner side, uniformly distributes the metal liquid to reduce the internal stress, improves the uniformity of the finished product, and facilitates subsequent removal of the gate.

This invention discloses an automatic control method for the sickle bend of a medium-thick plate rolling mill, belonging to the field of metal processing. The method includes billet heating and rolling, optimizing the steel rolling production scheduling principles and the roll crown configuration, dividing the work roll cycle into initial roll, intermediate roll, and final roll, and establishing scheduling principles for steel plate width and thickness. This invention significantly improves equipment stability and reduces the stock shortage rate.
