SU1402507A1 - Hopper for loose materials - Google Patents

Abstract

The invention relates to the means of storing and unloading bulk materials, rials using bins with devices that facilitate unloading of the material. The purpose of the invention is to improve the conditions for unloading the material due to its uniform heating. The hopper includes a housing 1 and a device for heating the material. The device is made in the form of a vertical air distributor 2 placed inside the casing, communicating through distribution openings 3

The invention relates to means X1 |) of aneni and unloading bulk materials using silos with pri-; Arrangements that facilitate material unloading.

A: The purpose of the invention is to improve the conditions for unloading material due to its uniform heating.

; Supplying the hopper with horizontal airways of a triangular profile with an apex angle not exceeding the angle of repose of the Bulk material and with holes in the lower edges allows for uniform ventilation and heating of the material, which, in turn, reduces the likelihood of arching.

; Figure 1 shows a silo for raw materials; figure 2 is a section in figure 1; on fig.Z - section bb nor figure 1; figure 4 is a horizontal outlet (section bb In figure 1). Bunker for bulk materials includes a housing 1 and a device for heating the material. The device is designed as a vertical air distributor 2 placed inside Kdpnyca, communicating through distribution holes 3 with horizontal air ducts 4 having a triangular cross-sectional profile with an angle oi at the apex that does not exceed the angle of repose of the bulk material (Fig.4). On the lower edges of the horizontal air ducts there are holes 5 arranged with decreasing along the direction 10

In addition, pitch 6 is installed at the ends of the air ducts. Holes 3 on the air distributor 2 are made with an increasing diameter from top to bottom in such a way that their total area is equal to the area of the air distributor cross section. The area of the holes 5 on each horizontal air duct is equal to the area of the corresponding distribution hole 3. For stability, the horizontal air ducts rest on the stops 7 attached to the housing 1.

The hopper for bulk materials works as follows.

Hot air from an autonomous generator, for example, a electrolytic calorifier, is supplied through the piping system under Pressure to the vertical air distributor 2 from the top. Through the air distributor, hot air moves down through the openings 3 to the horizontal air ducts 4. From the air ducts through the holes 5 air enters the hopper and is distributed throughout the material. Since the holes 3 are made with a diameter increasing from top to bottom,

and the openings 5 are arranged in increments decreasing towards the bunker body, the air pressure throughout the heating device is the same, which contributes to the uniform heating of the material.
