Description
The technical field is as follows:
the utility model relates to a palladium charcoal technical field especially relates to a material device is thrown to palladium charcoal.
Background art:
the palladium-carbon catalyst is a supported hydrogenation catalyst formed by loading metal palladium into active carbon, has the characteristics of high hydrogenation reducibility, good selectivity, stable performance, small feed ratio in use, repeated application, easy recovery and the like, and is widely used in the hydrogenation reduction process of petrochemical industry, pharmaceutical industry, electronic industry, perfume industry, dye industry and other fine chemical industries.
Because the palladium-carbon powder is flammable, and the hydrogenated material liquid generally contains a low-boiling point solvent or is a low-boiling point organic solution, the traditional manual feeding mode has the following defects: 1. the static electricity generated after the palladium-carbon rubs with the inner wall of the hydrogenation kettle is easy to enable solvent steam and air to generate deflagration; 2. the powder feeding is easy to make the catalyst float and attach to the surfaces of the inner wall of the hydrogenation kettle, the inner coil pipe and the like, and the danger is easy to cause when the next feeding is carried out.
The utility model has the following contents:
to the above problem, the to-be-solved technical problem of the utility model is to provide a material device is thrown to palladium charcoal, including feeder, sight glass lamp, searchlight sight glass, take the window to open fast throw the material hole, operate glove hole, nitrogen gas pipe, hydrogenation material liquid pipe, evacuation pipe, throw material device unloading pipe, couple and vacuum tube, the positive below of feeder is provided with sight glass lamp and searchlight sight glass, openly is provided with takes the window to open fast throw the material hole, is provided with the operative glove hole in the left and right sides, the feeder top is connected with nitrogen gas pipe, hydrogenation material liquid pipe and evacuation pipe respectively, the feeder below is connected with the unloading pipe, the unloading pipe extends into in the hydrogenation cauldron, the feeder inner wall is provided with the couple.
Preferably, the blanking pipe extends into the hydrogenation kettle by 15 cm.
The utility model discloses beneficial effect: the utility model discloses adopt nitrogen protection when palladium charcoal throws the material to through the vacuum suction hydrogenation cauldron after with the hydrogenation feed liquid mixing, avoid palladium charcoal, hydrogenation feed liquid steam and air contact to produce dangerously, and throw material device unloading pipe and extend into 15cm in the hydrogenation cauldron, avoid palladium charcoal feed liquid along hydrogenation cauldron inner wall flow-down back, lead to palladium charcoal dry powder to glue on the wall because of the feed liquid volatilizees.
Description of the drawings:
for ease of illustration, the invention is described in detail by the following detailed description and accompanying drawings.
FIG. 1 is a schematic view of the overall structure of the present invention;
