Abstract

The invention relates to the storage and distribution of bulk materials, can be used to dispense caking and sticking materials and is an improvement of the invention according to the author. St. No. 931519. The purpose of the invention is to improve the uniformity of the material feed. The hopper contains a cylindrical body 1 and the bottom of a disk 2 with a discharge slot 3. A scraper 8 is installed on the rear edge of the slot along the edge of the slot that can move in a vertical plane, which is rounded to the side of rotation of the disk, which ensures efficient material capture. At the same time, the interconnection between the annular protrusion 15c and the sealing material is carried out by pressing the rods 19 by means of springs 20 through the clamp 18 onto the sealing material 16, which prevents the material from spilling out through the gap 14.

Description

The invention relates to the storage and distribution of bulk materials, can be used for the dosage of caking and sticking materials, such as milk powder, and is an improvement of the invention according to the author. St. No. 931619.

The aim of the invention is to improve the uniformity of the feed material.

FIG. 1 shows a bunker, cut, front view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 is a view B in FIG. 3; in fig. 5 shows a section B-B in FIG. 3

The bunker contains a tsipindric body 1 and a bottom in the form of a disk 2 with a radial discharge gap 3. The disk 2 rests on the guide rollers 4. The outer edge 5 of the slot 3 is located under the lower edge of the housing 1, and the inner edge 6 passes through the center of the disk 2. At the rear a radial edge 7 of the discharge gap 3 in the direction of rotation of the disk 2, perpendicular to it, a scraper 8 is fixed with the possibility of vertical movement in the grooves of the lugs 9 fixed in the radial edge 7 of the disk 2. The position of the scraper is fixed by screws and nuts 10. The scraper 8 is above the disk ohm 2 has a rounded shape in the direction of rotation of the disk 2. The scraper ends with a cutting edge 11. Under the front radial edge 12, in the direction of rotation of the disk 2, a flap 13 is installed to adjust the width of the slit 3. The gap 14 between the lower edge of the housing 1 and the disk 2 is sealed with an annular ledge 15 of the disk 2. The protrusion 15 is interconnected with the sealing material 16 inserted into the annular seat 17 fixed to the lower part of the outer surface of the cylinder body 1. Between the annular seat 17 and the sealing material 16 there is an annular washer 18 interconnected from the side of the annular seat 17c with spring-loaded rods 19. The springs 20 are inserted between the support rings 21 of the rod 19 and the brackets 22 fixed to the outer surface of the cylinder 1 1.

A conic chute 23 is installed under the disk 2. The rollers 4 are rotatably secured to the brackets 24, which, in turn, are rigidly connected to the housing 1 and to the conical chute 23. The plate 25 is attached to the housing 1 for vertical movement of the plate 25. in rotation from the gear drive 26. For such materials, which, after unloading from the bunker, require mixing in water (e.g. milk powder), nozzles 27 are installed in a comic bag,

associated with a common water supply manifold 28.

The bunker works as follows. In accordance with the required performance, the height of the scraper 8 (h) above the disk 2 is set, the width of the slit 3 through the valve 13, then the plate 25 is fixed above the scraper with a gap. Next, the gear drive of the drive is turned on

26. When the disk 2 rotates, the scraper 8 evenly captures the material located above the disk 2 with a thickness h, and evenly points towards the discharge gap 3, from where it pours out of the hopper through the conical chute 23. During one revolution of the disk 2, the scraper 8 encloses the entire area of the circle under the body 1 with the height h of the material and its continuous dosage is unloaded. If flour or milk powder is discharged,

which are subsequently mixed with water in the respective mixers, the valve is opened and the water from the collector 28 and the nozzles 27 are directed into the volume of the conical chute 23, where preliminary

mixing with the paged material. In this case, a constant relationship between the rotating annular protrusion 15 and the sealing material is carried out by pressing the rods 19 through the springs 20 through the ring-shaped washer 18 onto the sealing material 16, which prevents the loose material from spilling out through the gap 14. The plate 25 keeps the lower layers of material from rotating together with disk 2.

The installation of the scraper on the back radial edge of the discharge gap in the direction of rotation of the disk, perpendicular to it, as well as the rounded shape of the scraper above the disk ensures that the disk rotates efficiently grip sticking bulk material above the disk and a continuous metered discharge. At the same time, the cutting edge of the scraper when gripping the material reduces the resistance forces

cut.
