SU793874A1 - Hopper for loose materials - Google Patents

Description

one

This invention relates to the field of storage and distribution of materials, in particular, to silos for bulk cargo.

A known hopper for bulk materials, comprising a body, a bottom part. which is made in the form of a cone with a pin hole, a cargo divider mounted inside the case on a vertical rod with a cone gate at the end of tl.

A disadvantage of the known device is that it is intended only for coarsely dispersed materials and cannot provide uniform and controlled movement of fine materials.

The aim of the invention is to increase efficiency in operation, by ensuring a uniform and adjustable supply of material.

For this purpose, the material divider is made in the form of an aperture, with slits along the perimeter, and the said cone valve is located inside the housing, and

total area of the slots. The diaphragm is 1-1% of the total surface area of the diaphragm, and the horse shutter diameter is 0.5-0.9 of the diameter of the base of the diaphragm.

FIG. 1 shows a sectional bin; in fig. 2 is a section A-A of FIG. one.

The bunker consists of a cylindrical body 1, which in the lower part turns into a cone. Inside the housing there is a rod 2, to which an adjusting cone bolt 3 is fastened at the bottom. The rod is screwed into the threaded bushing 4 located on the cover 5 of the bunker. A taper diaphragm 6 is fixedly mounted in the body of the hopper, with slots around the periphery of the material, which has a sliding fit on the rod. Dimb 7 is mounted on the top of the stem to fix the amount of stem rotation. A vibrator 8 is mounted on the cover. The bunker is attached to the bed 9, to which the carrier gas is fed through the opening 10. The feeder has vacuum seals 11 and a stem seal 12. The plug 13 serves for. pour the powder into the hopper. The work is carried out as follows: unscrew the plug 13, through which the necessary amount of material is poured. If it is necessary to force the air out of the bunker, the inert gas is fed through the opening 10. At that, the gas pipeline is blocked at the spring choke. After purging the feeder, close the npo6ky 13, open the gas line, turn on the vibrator 8, raise the adjusting cone gate 3 by means of the pinch 2 to a certain height necessary to obtain the required material flow and install a certain flow rate of the carrier gas (the diaphragm remains stationary due to sliding landing on the rod 2. The material is poured down by the carrier gas, which flows through the opening 10 in the bed 9 and is fed into the plasma torch by means of a gas pipeline, feeding mine to the outlet connection. To better material the surface of the bunker body, the diaphragm and the shutter are polished. In order for the vibrations to not over 7 4. to be given to other nodes, the buiker is mounted on shock absorbers. BACKGROUND OF THE INVENTION Bunker for bulk materials, mainly fine powders, comprising a body, the lower part of which is made in the form of a cone with an outlet, a material divider mounted inside the body on a vertical rod with a cone gate at the end, characterized in that in order to increase efficiency in operation, by providing a uniform and adjustable material supply, the material divider is made in the form of a diaphragm with slots around the perimeter, and the cone gate is placed inside The total area of the aperture slots is 1–1O% of the total surface of the diaphragm, and the diameter (year of the conical shutter is D, 5-O, 9 diameters of the base of the diaphragm.
