SU44119A1 - Double brown roll with two baths - Google Patents

Description

The rolls operating in the baking industry give the better efficiency than the thicker their charge, since in this case less energy is expended in throwing excess water through the hill.

However, in order to obtain a proper rut of mass in the bath, it usually has to be diluted to a concentration of 4-6%. New types of roll advertise the opportunity to work at a concentration of up to 9%, which has not been practically achieved yet.

Two-tier rolls (for example, Taylor roll), equipped for pumping mass with conventional pumps, also cannot work on a mass of dense concentration and therefore do not, however, use any superanteous HpeimyniecTB.

The object of the present invention is a roll, having one or two baths arranged one above the other, connected vertically or by inclined channels, the mass passing through the hill in the upper bath falling into the bottom and then again continuously using a vertical or inclined head. bucket elevator is fed into the upper tub, acting under the IOGL1 drum and bar.

Fpg 1 shows a longitudinal vertical section of a roll, and FIG. 2 - its top view; the numbers denote: 1-knife drum, 2 - a bar with knives, 3-top bath, 4-connecting duct or nozzle, 5 - bottom bath, having an inclined bottom, along which mass flows to the elevator, 6-bucket elevator, 7- rotating, and with the damper, when the roll is in a vertical position, and when the mass is released, it takes an inclined position and guides the mass into the exhaust pipe 8.

Material is loaded into the roll through the hatch 11 located on the side. The release can be carried out depending on the local opening and through the pipe 10. The drum is eased and added by one of the most commonly used methods and are not shown in the drawing. The feed mass produced by the elevator must be regulated by transmission from a motor with a variable speed, transmission by means of conical drums or a system of junction boxes used in the paper industry (such as used in bulk tanks), as well as other possible adjustment methods.

The elevator makes it possible to move the mass, the concentration of which can be increased even higher than its yield strength, and therefore the roll of the proposed i design can with much more; success, than the rolls of other systems, handle thick mass. The mass of the concentrate, of the order of 12-15%, also has fluidity, but cannot be processed in rolls of other structures, whereas the proposed roll can easily grind it.

The advantage of a roll is the very significant saving of energy used for grinding.

The subject matter of the invention.

A two-roll roll with two baths, one above the other, which is characterized by the fact that in order to feed the mass from the bottom of the varsha to the top, a vertically nl inclined bucket elevator is used.
