(5) BUNKER DEVICE

one

The invention relates to storage devices for bulk solids.

A bunker storage device for bulk solids is known, which has a cylindrical conical shape with an outlet opening in the bottom. 1.

However, when the device is several times the height of its cross section, the bottom layers of the stored product are under great pressure, compacted and can form static or dynamic arches that prevent the material from flowing evenly and impair its quality.

A bunker device is known, comprising a cylindrical vertical body divided into sections with by-pass openings and a shaft mounted with a rotatable shaft in the case with blades 2.

However, this device is cumbersome in design and does not preserve the quality of the product.

The aim of the invention is to preserve the quality of stored products.

The goal is achieved by the fact that in a bunker device containing a cylindrical vertical housing divided into sections with bypass openings and rotatably mounted in a housing with a hoist, each section is provided with a bottom, the bypass opening has a sector shape and is located in the bottom The body and shaft; and the connectors at the points of their connection with the bottoms, and the blades are fixed in each section in pairs with a potential axial rewrite, while the holes in the sections of each section are evenly spaced. and for connection with an inert gas supply system, furthermore, the device is provided with a lid fixed in the upper section. .

Figure 1 shows the bunker system, general view; figure 2 - section 3 jfl, -A in FIG. 1; on fig.Z-section bb in figure 1.

The device comprises a cylindrical body made in the form of several intermediate interchangeable sections 1 and the lower section 2, a vertical shaft 3 and the upper cover 4 with a loading opening 5. The body is made inlaid with the ability to adjust the number of sections. In the bottom 6 nines (section 2, there is a discharge opening 7 with a discharge dispenser.

Each section 1 is made in the form of a shell attached to the bottom 8, in the center of which is placed a bowl 9 for securing the vertical shaft 3, and the sides are provided with openings 10 for supplying an inert gas. The bottoms of 8 sections 1 are provided with bypass openings 11, which are sector-shaped.

The body sections are fastened together by fastening elements along flanges 12, provided with grooves 13, designed to install the sections, with the possibility of displacement of the bypass holes 11 relative to each other on the T-board depending on the type of stored product.

 The vertical shaft 3 is made of interchangeable and equally high components with sections, interconnected in the cups 9. To each component of the vertical shaft 3, the blades 1 and 15 are mounted with a possibility of moving along the height, placed respectively in the upper and lower parts of each section, and the blades 15 are located with a minimum gap relative to the bottom 6 and 8.

Each section 1 and 2 is provided with an annular manifold 16 connected by means of valves 17 to an inert gas supply pipe 18. The annular manifolds 16 are mounted above the level of the bottoms 6 and 8 on the outer side of the sections and are provided with fittings 19 entering the openings of 10 shell sections.

The device works as follows.

Before loading the device, depending on the type of stored product, the sections of the body are installed with the offset of the bypass holes 11 relative to each other at a desired angle, for example, when storing dry mashed potatoes in the form of grains - with the offset of the bypass holes 11 by 90

The device is loaded after the vertical shaft 3 is rotated. The product is fed through the loading opening 5 into the upper section 1. With the help of the rotating blades 15, the product advances to the bypass holes 11 and passes through them sequentially fills all the sections of the device. At the same time, the rotating blades 15 produce leveling of the product by the volume of sections 1 and 2 and the rotating blades 1 level the product cone formed during loading, ensuring that the entire volume of the sections is completely filled. When the device volume is completely filled, the vertical shaft 3 is turned off.

During operation of the proposed device, valves 17 of the pipeline 18 periodically turn on and inert gas, such as nitrogen, flows into the annular manifold 1b, from where it is fed through fitting 19 to the lower part of sections 1 and 2. Inert gas, as a lighter one, rushes up through the product layer whereby the product is uniformly and intensively processed throughout the entire volume of the device.

To unload the product, the vertical shaft 3 is rotated and the product is uniformly unloaded from the device using a discharge dispenser.

The speed of loading and unloading of the product is regulated by the frequency of rotation of the vertical shaft 3.

Making the housing in the form of interchangeable sections provided with bottoms with bypass holes, as well as making sections with the possibility of shifting the bypass holes relative to each other by 1B, prevents the upper layers of the product from being pressurized to the bottom and, thus, virtually eliminates caking of the product, which at adverse conditions contribute to the deterioration of its quality.

The presence of blades attached to each component of the vertical shaft and located in the upper and lower parts of the sections with the ability to move in height, allows you to completely fill the volume of the mouth (product). Installation of sections with offset by-pass holes and the proposed arrangement of the blades ensure uniform filling and flow product from each section.

The use of an annular collector with nozzles for introducing the inert gas installed on the outside of each section above the bottom level allows qualitative and uniform processing of the product to the volume of the device, which makes it possible to use the proposed device for long-term storage of various products and to ensure the preservation of their quality. .

The construction of the case with the type-setting of interchangeable sections, each of which is provided with a cylindrical shell and a bottom with an overflow hole, makes it possible to eliminate cumbersome jumpers and make the most of the volume of the device.

In addition, the design of the body as a set in the form of separate interchangeable sections and the execution of the shaft from its component parts makes it possible to adjust the height of the proposed device depending on the height of the rooms. This allows you to expand the possibilities of using the proposed device in different height areas, both in newly built and existing ones and, thus, significantly reduce investment in the construction of special structures.
