Described feeder is that cylinder and the feeder slide plate that has opening on inclined plane and the sidewall forms by the bottom, and the feeder slide plate is connected on the cylindrical sidewall, can slide up and down at opening part, opens opening or closes opening being used for.
Angle between described cylinder bottom and its perspective plane in the horizontal direction is the 30-60 degree.
Described feeder by metallic cylinder, be in metallic cylinder bottom, the cloth bag and the knot that can be undone by a pull that are connected as a single entity with metallic cylinder form.
The diameter of described feeder is 20-80mm, and less than vertical tubulation diameter, length is 200-1200mm, and the quantity of feeder is 10-100.
The circular hole of described storagetank bottom is 10-100, and Circularhole diameter is slightly smaller than the diameter of feeder.
In order to realize above-mentioned the second purpose, by the following technical solutions:
A kind of charging process that adopts the feeding device loading catalyst of above-mentioned fixed bed reactors tubulation loading catalyst is characterized in that: described method operating procedure is:
One, feeder is moved near storagetank bottom feeder top perforate part is alignd with the storagetank bottom opening, by storagetank catalyst is poured in row's feeder it is filled it up with;
Two, make feeder slowly drop to reactor tubulation bottom;
Three, open feeder, so that catalyst falls into the reactor tubulation.
Described catalyst is graininess.
Feeding device and the charging process of fixed bed reactors tubulation loading catalyst provided by the invention, because being provided with, feeder bottom or side can open or mobile structure, allow again catalyst fall in the tubulation after catalyst can being dropped to like this fixed bed tubulation bottom, avoid catalyst breakage.In a single day each feeder completes, and its volume is certain, therefore can be implemented as the purpose of the differing heights Quantitative charging catalyst of fixed bed tubulation.
