Description

The invention relates to devices used in the food-concentrate industry for the preparation of multicomponent dry milled strength compositions and uniform mixing of the components.

It can also be used in the confectionery, animal feed and milling industries and in other industries, when it is necessary to compile multicomponent mixtures of bulk and powder materials.

Known feeder for bulk materials containing a vertically mounted sectional housing with top

inlet and lower outlet openings, a cylindrical nozzle concentrically covering the lower part of the casing with the possibility of movement in a vertical plane relative to the casing, mounted in series under the outlet openings of the casing fixed and rotary disks. discharge scrapers and mixer.

A disadvantage of the known feeder is insufficient dosing accuracy with the accumulation over time of dose calibration errors for individual components, as a result of which at least one of the components of the mixture is overspended.

In addition, if the composition provides for a very low content of at least one component, its uniform mixing with the rest of the components cannot be ensured by the receiving adaptation of this device.

The aim of the invention is to improve operational properties by increasing the accuracy of the dosage of the components and the efficiency of their mixing. .:

This goal is achieved by the fact that in a bulk material feeder comprising a vertically mounted sectional housing with feed and outlet openings, a rotary disk mounted coaxially to the latter under the housing, discharge scrapers and a mixer, under each outlet between the housing and the drive with the possibility of moving - no grooves are installed in the radial direction, triangular-shaped holes are evenly made in the rotary disk, the number of which is a multiple of the number of grooves and does not exceed it. turned by the base of the triangle to the center of the disk with a distance between them exceeding the width of the outlet of the trough, and the mixer has a fixed funnel mounted in a cylindrical housing coaxial to the rotary disk, under which another rotary disk with scrapers is placed on the shaft common to the first disk.

In addition, the mixer is made a lot of Russian, and sections of the body are made in the form of bins.

Figure 1 shows a diagram of the proposed feeder; figure 2 is a section along aa in figure 1; in Fig.3 is a section along BB in Fig.1; figure 4 is a section along bb in figure 1; figure 5 is a section along G-D in figure 1.

The feeder for bulk materials consists of bins 1 for mixed components, the lower part of which ends with a conical bottom 2 and nozzles (holes) 3, and each hopper is suspended on the sensors 4 of the weighing device (not shown), grooves 5 (according to the number of bins) with outlet pipes (holes) 6 and telescopic nozzles 7, screw devices 8 for moving the grooves 5 and fixing their selected position, shaft 9 with a stop device in one of the fixed positions (not shown) with conical dividers 10, disk and a dispenser 11 with triangular holes 12, disks 13 of the mixer, funnel 14 with scrapers 17 rigidly fixed on them, discharge

holes 18, the cylindrical casing 19 and the drive device (not shown).

The components of the mixed materials located in the hoppers 1, through the discharge nozzles (holes) 3 fill the grooves 5, and when they reach the level of the lower end of the discharge nozzle 3, the material outlet is blocked.

The feeder drive through the shaft 9 rotates the dispenser disk 11 and the mixer disks 13. When the dispenser disk 11 rotates, the triangular holes 12 sequentially bypass the telescopic nozzles 7 of the discharge nozzles (holes) 6 of the grooves 5 and, depending on their radial distance from the center, the mixture components are metered through the holes 12. The components that enter the mixer upper funnel 14 are collected into the total mass and by divider 10, the material is spread on the first disk 13 of the mixer. The scraper 15 has a slope relative to the radial beam, which allows the mixture to move from the center to the edge of the disk. Further on. subsequent mixer disks, these processes are repeated. In the lower rus, the ready-made composition is scraped out by the scrapers 17 from the feeder through the discharge opening 18.

The scrapers 15 on the disc of the dispenser 11 serve to clean it (to prevent the accumulation of component residues).

v The capacity of the feeder, all other things being equal, depends on the number of slots 12 on the disk 11 and its rotational speed.

When equipping enterprises with the proposed feeder, the production area is reduced by more than 2 times, and the energy consumption of dosing and mixing operations is 1.5 times. Significantly improved dosage accuracy and mixing efficiency of the components.
