Abstract

The invention relates to devices that provide a uniform flow of bulk materials from bunkers and the like and can be used in chemical, food and other sectors of the national economy, being additional to as well. 1323503. The aim of the invention is to increase the reliability of operation. This is achieved by the fact that in the device the funnel is made in the side surface on the side opposite to its discharge opening, shifted upward relative to the upper edge of the latter, and its bottom - with parallel sides under the hole to form with the latter a channel to divert material from the discharge opening and return it to the funnel. 2 Il.

Description

(pui.r

The invention relates to devices that ensure uniform flow of bulk materials from bunkers and similar containers, and can be used in the chemical, food, construction and other fields of natural economy.

i The purpose of the invention is to increase the reliability of the work.

FIG. 1 schematically shows the proposed feeder, vertical section; in fig. 2 - section А-А on ф | и г 1.

The feeder contains a hopper 1 with discharge pipe and 2 and vertically

a fixed funnel 3 fixed to the support flange L and rotating under the action of the engine (not pointed). On the side surface is a crow-20, formed by the sides 8 and

 -

rollers 10 prevent radial displacement of the support flange. The material entering through the discharge nozzle 2 of the hopper 1 into the rotating funnel 3 rolls down the inclined bottom 7 and under the action of centrifugal force through the hole 5 is evenly distributed around the circumference of the receiving hopper. A material that has a tendency to stick, due to the presence of an additional hole 6 on the wall, cannot climb it high. On the inclined bottom 7, a compacted layer of material is formed which does not hinder the passage of the main material flow. In the event of a funnel overload, a small part of the material rises along

Ki 3 is made unloading opening 5 and an additional hole 6, located above the discharge from its opposite side. The funnel has an inclined bottom 7 and vertical sides 8. Adjacent to the bottom of the additional hole 6, the bottom

with sides 8 forms an obliquely directed upward tray. In the inner cavity of the support flange, the support conical roller 9 and guide cylindrical oliki 10 with the clamping element are radially mounted, and grooves 11 for the wedge-terminal transmission connecting the engine with the funnel 3 are outside. 12.

The feeder works as follows.

The rotation from the engine is transmitted through the climber: a temporary transmission1 1 to the supporting flange k of the funnel 3. Flange 4.- freely rolls along the tapered rollers 9, pressing them under the action of gravity, and the guides

sloping bottom 7, and pouring over the lower edge of the hole 6 into the funnel. Material cannot rise up to the discharge nozzle 2, therefore cases of locking the funnel are excluded. The sealing ring 12 prevents the dust generated during operation of the feeder from penetrating into the turntable.
