DISTRIBUTION DEVICE

Patent DE2632984C3

Container filling device with solid particulate matter.

Apparatus for loading an enclosure with particulate solids includes a loading hopper, a discharge chute (integral with the hopper), and a movable member disposed below the outlet opening of the chute. The movable member includes a shaft driven in rotation by a motor and flexible, moderately hard deflecting strips, which are articulated to the shaft or to a structure rigidly integral with the shaft, so as to spread out from the shaft at an angle by the effect of centrifugal force when driven in rotation. At least one discharge opening is provided in the side wall of the hopper and/or of the chute in the direction of the rotating deflecting strips.

Device for delivering a measured charge of a flowable powder

A device for delivering a measured charge of a flowable powder comprising a storage container, a vertical piston rod and a buffer vessel, the rod being provided with a constriction which reaches into the storage container when the piston rod is at the upper end of its stroke, and reaches into the buffer vessel when the piston rod is at the lower end of its stroke. In the latter position the piston rod fits tightly in a first channel which is in connection with a second channel which has a clearing rod. At one end of its stroke the clearing rod occupies the second channel and at the opposite end of its stroke establishes a communication between the first channel and the open end of the second channel.

Device for delivering a measured charge of a liquid or flowable powder

1370492 Delivering measured quantities FARBWERKE HOECHST AG 20 Dec 1971 [18 Dec 1970] 59085/71 Heading B8N [Also in Division B1] A measured charge of liquid or powder is delivered under relatively high pressure from storage container 3, Fig. 1, to reactor 8 by (a) causing piston 2 to be raised so that the powder or liquid can flow into constriction 1 to form the measured charge, (b) lowering the piston to allow the measured charge to pass into chamber 4, (c) lifting piston 2 to allow the charge to fall down channel 5 into channel 6, Fig. 2, whereupon (d) gas which is inert in the reaction in reactor 8 and is at a pressure source atmospheres greater than the pressure in reactor 8 is introduced from valve 15, Fig. 1, to blow the charge into reactor 8 and (e) piston 7 is moved to the left to move any remaining charge into the reactor. Suction channel 13 normally prevents gases from reaching chambers 3 and 4, however, should a blow back occur, chamber 4 protects the contents of chamber 3.

Method and apparatus for handling fluidizable finely divided solid materials

Improved control over particulate feed

Olefin polymerization reactions, particularly those performed in a gas phase fluidized bed process, benefit from a uniform feed of catalyst. Poor control of the feed rate can cause problems due to temperature fluctuations within the fluidized bed. Disclosed herein is a method for controlling the flow of supported particulate catalyst through a unit body rotary disc catalyst feeder, the method involving a feeder with means for feeding an inert gas, such as nitrogen, to the upper surface of the metering disk. The method describes controlling the rate of catalyst leaving the feeder by changing one or more of the speed of rotation of the metering disk, the pressure of nitrogen fed to the upper surface of the metering disk, and the volume of nitrogen fed to the upper surface of the metering disk.
