The invention discloses an up-flow reactor and an application thereof. The up-flow reactor comprises a reactor shell, and a catalyst bed support grid and a catalyst bed are sequentially arranged in the reactor shell along the material flow direction. The lower part of the bed and / or the upper part of the catalyst bed is provided with an elastic support layer, the elastic support layer includes a plastic elastomer bed and a ceramic ball support layer, the plastic elastomer bed includes several plastic elastomer units, the plastic elastomer The elastomeric unit includes particles made of an elastic material, and there are voids between and within the plastic elastomeric units as passages through which fluid flows. The present invention also provides an application of the upflow reactor. The plastic elastomer bed in the up-flow reactor of the present invention can be deformed synchronously with the expansion and contraction of the catalyst bed, so as to prevent the bed pressure drop from increasing due to particle abrasion during the floating process of the catalyst, and to ensure that the up-flow reactor has a stable performance. Long-term stable operation.

A high-temperature superconducting coil shielding current elimination device is composed of a skeleton, a cold head, a high-temperature superconducting strip, a stainless steel strip, a terminal, an AC power supply and a DC power supply. High-temperature superconducting strips and stainless steel strips are not wrapped with insulating materials on the surface, but are wound side by side on the skeleton. There are grooves on the inner side of the frame to install terminal posts, and round holes are opened on the outside of the frame to install terminal posts and cold heads respectively. The inner side of the high-temperature superconducting strip and the stainless steel strip share a terminal, and the outside is connected to an independent terminal. The high-temperature superconducting strip is connected to a DC power supply to generate a static magnetic field in the central area of ​​the coil. The stainless steel strip is connected to an AC power supply to provide high-temperature superconducting The current flowing between the layers of the strip and the stainless steel strip causes heating of the interlayer resistance, thereby reducing the critical current in the high-temperature superconducting coil and further eliminating the influence of the shielding current.

The invention discloses a double-worktable-exchange device of a laser cutting machine, and belongs to the technical field of laser cutting machines. The double-worktable-exchange device comprises a first worktable and a second worktable, wherein the first worktable and the second worktable are arranged on a worktable rail of a lathe bed, and position exchange of the two worktables is achieved through driving of a chain transmission mechanism. The worktable guide rail is divided into a lifting worktable outer guide rail with the middle high and the two ends low, a lifting worktable inner guide rail with the middle high and the two ends low, and a linear horizontal movement worktable guide rail, wherein transition of each middle high section and the corresponding low sections at the two ends is achieved through inclined sections. Two front side wheels at one end of the second worktable are arranged on the lifting worktable outer guide rail, and two rear side wheels at the other end of the second worktable are arranged on the lifting worktable inner guide rail. The first worktable is arranged on the horizontal movement worktable guide rail. The device does not need to be provided with a lifting mechanism, exchange between the two worktables can be completed by only reasonably designing the guide rails where the worktables operate, the structure is greatly simplified, the manufacture cost is reduced, and the double-worktable-exchange device has the beneficial effects of being convenient to operate and easy to maintain.

The invention relates to a medical functional device (900) having a valve seat (803) for a non-return valve (1), wherein said non-return valve (1) is embodied such that, in addition to the first position, by By exerting a force on a segment of the check valve (1) and / or by moving or displacing the segment, the check valve (1) also assumes a second functional position, the first position Suitable for gas disinfection, in said second functional position said non-return valve assumes a non-return or non-return function, wherein said non-return valve (1) is implemented such that it achieves transfer to said first in the second position and remains in the second position after release or insufficiency of the force and / or movement.

The invention relates to an air flow channel assembly of a baffle plate, comprising a flow channel and a blowing device, the flow channel includes an air inlet part and an air outlet part, the air inlet part and the air outlet part form a communication structure, and the air outlet part forms a communication structure.
