The aim of the invention is to prevent leakages in the zone of the peripheral sealing edge, to guarantee an unimpaired filter capacity during feeding and to facilitate operation of the filter press without an external supply line and outgoing connection lines. To this end, the filling element (2) is disposed on a joining piece (5) that extends outside a plate level and within a sealing edge (27) on the periphery of the filter plates (1M, 1K) and that can be linked with a filter plate (1M). In the filtering position, the filling elements (2) form a suspension supply channel (22) that extends through the filter plate package and are sealingly wedged between adjoining filter plates (1M, 1K).

The invention relates to a disc type drier. The disc type drier comprises a machine shell and a drying mechanism arranged in the machine shell, wherein the drying mechanism comprises a shaft rod and shaft heads sleeved at the two ends of the shaft rod, and the shaft heads are provided with steam inlets and condensate outlets; a plurality of guiding pipe groups are uniformly distributed on the shaft rod, guiding pipes of each guiding pipe group are uniformly distributed on the same shaft section of the shaft rod, and each guiding pipe group comprises a plurality of condensate water guiding pipes and a plurality of steam guiding pipes; heat transfer discs are sleeved on the shaft rod by corresponding to the guiding pipe groups one by one, and the heat transfer discs are formed by welding two disc-shaped pieces in an opposite manner; a radial gap formed by the two disc-shaped pieces is internally provided with a plurality of guiding plate groups, and the guiding plate groups are arranged in match with the condensate water guiding pipes. The disc type drier provided by the invention has the advantages that large amount of condensate water in the heat transfer discs can be rapidly discharged through the condensate water guiding pipes, and the heat exchange efficiency is high; the guiding pipe groups and the heat transfer discs are uniform to distribute and drain, a water hammer effect is unlikely to cause, the damage risk of the shaft rod is reduced, the service life of the drier is prolonged, the driving energy consumption is reduced, and the maintenance cost is reduced.

Provided is support structure of a pipe nut improving assemblability. The structure comprises a pipe nut 1 where one end side 1a is supported by matching to a hole part of a vehicle body frame 10, a bolt which is fastened to the pipe nut 1 through the hole part and supports a supported body to the vehicle body frame 10, and a reinforcing member 2 which is fixed to the vehicle body frame 10 and contacted to the other end surface 1b of the other end part of the pipe nut 1, and constituted so as to be mounted by welding the other end surface 1b of the pipe nut 1 and the reinforcing member 2.

The invention relates to the technical field of grinding machines, in particular to a grinding system and a grinding method. The grinding system comprises a workbench provided with a via hole, a grinding disc suitable for being conveyed into an inner cavity of a to-be-ground object, a rotating main shaft and a grinding disc automatic installing mechanism; the rotating main shaft has a first working position and a standby position, wherein the standby position is the position of the rotating main shaft located below the workbench, and the first working position is the position that the rotatingmain shaft upwards penetrates through the via hole to extend into the inner cavity to install or detach the grinding disc; the rotating main shaft is located below the workbench, the stroke of the rotating main shaft is shortened, loading and unloading of a workpiece are facilitated, and influences caused by the fact that a driving component is located above a workbench face on layout of a workpiece loading and unloading mechanical arm on the workbench are avoided; and the rotating main shaft conducts pulling from top to bottom to conduct grinding, a grinding head is provided with downward pulling force, the risk of bending due to large stress of a grinding shaft is reduced, and the structure of the driving end is simplified.

A thermally processed camshaft quick-loading anti-bending tooling, comprising a cube or cuboid frame jointly surrounded by a plurality of upper support frame plates (1), lower support frame plates (2) and vertical support frame plates (3). The bottom surface of the support frame plate (1) is fixedly connected with a plurality of I-beams or H-shaped steels (6), and the top surface of the lower support frame plate (2) is fixedly connected with a plurality of channel steels (7). The red hot camshaft can The gap between two adjacent I-beams or H-beams (6) is loaded and snapped between the lower legs of two adjacent I-beams or H-beams (6), and part of the shaft section at the lower end of the camshaft can Stretch into the gap space between the channel steel (7) two legs. The hot-processed camshaft fast loading anti-bending tooling and corresponding method of the present invention can quickly load the red-hot camshaft, prevent bending caused by traditional horizontal placement and boxing, and have a large capacity, and can quickly calculate the loading amount, comprehensively Improve product yield and turnover efficiency.
