This utility model discloses a textile finishing and dyeing machine, relating to the technical field of textile processing equipment. It aims to solve the technical problem that current textile finishing and dyeing machines are inconvenient for removing excess dye from fabrics that have passed through the dyeing vat. The machine includes a main body. Through its designed cleaning structure, this utility model adjusts the relative movement of two sets of clamps inside the cavity during fabric dyeing. The clamps apply pressure to the fabric. When the two sets of fabric rollers in the main body of the dyeing machine repeatedly unload and reload the fabric, the fabric passing through the dyeing vat first passes through the cavity. Then, the two sets of clamps in the cavity squeeze out excess dye from the fabric. The fabric rollers in the main body then unload and reload the fabric with the squeezed-out excess dye, thus avoiding a large amount of excess dye remaining on the fabric and preventing dye splashing during the unloading and reloading process.

The invention provides a particle discharging device and method for a Tokamak divertor area. The device comprises an adsorbent pump unit arranged in a divertor area and a gas channel structure communicated with the divertor area, and is used for capturing and discharging neutral particles generated by interaction of plasma and divertor components. The adsorbent pump unit is made of a non-evaporation type adsorbent material, has high adsorption capacity on hydrogen and isotopes thereof, can keep stable structure and working performance under the condition of high temperature, and is suitable for a high-heat-load and high-particle-flux operating environment in a divertor area. The in-situ air exhaust of the neutral particles is realized in the divertor area, so that the transport path of the particles is shortened, and the response speed and efficiency of particle discharge are improved. Meanwhile, the particle discharging device has large air extraction capacity and effective extraction speed, is suitable for tritium-related application scenes and operating environments with neutron irradiation, and has good engineering application prospects.

The utility model relates to the technical field of corrugated paper production, in particular to a corrugated roller flow guide structure which comprises a corrugated roller, a bearing is arranged on a shaft tube of the corrugated roller in a sleeving mode, an air guide cover is installed at the end of the shaft tube, a flow guide pipe is arranged in the corrugated roller, the interior of the flow guide pipe is divided into a plurality of main flow cavities, each main flow cavity is further divided into a plurality of branch flow cavities, and the branch flow cavities are communicated with the main flow cavities. A flow dividing pipe is arranged in each flow dividing cavity, the flow dividing pipes arranged in the flow dividing cavities corresponding to the main flow cavities are connected to the same air pipe, and the air pipes of the main flow cavities form an air pipe bundle which is communicated with an external air exhaust structure. The flow guide pipe is arranged on the inner side of the corrugated roller, the flow guide pipe is divided into a plurality of main flow cavities which are used for discharging condensate water, and the flow dividing cavities in the main flow cavities can be suitable for small water flows, so that the discharging effect of the condensate water in the corrugated roller can be further improved.

The utility model relates to a kind of diamond trimmer, include: substrate;At least one first abrasive island, form in the one side of the substrate;And at least one protruding part, form in the one side of at least one first abrasive island relative to the substrate, wherein: the substrate, the at least one first abrasive island and the at least one protruding part are integrally formed, since omitting assembly process in forming process, and avoid using composite material or metal material, thus can greatly improve manufacturing precision and prevent pollution;In addition, the arrangement form of first abrasive island is various, after combining the protruding part of multiple shapes, can be adapted to the demand and use scene of various grinding, and can ensure that grinding fluid and grinding debris can flow smoothly and discharge in the process of diamond trimmer rotation and sweeping.
