SU35095A1 - A device for converting boiled substances into lumpy form - Google Patents

Description

The proposed device is intended to transform the agitated substances into a lumpy form in the molding box by means of pneumatic separation of the liquid, and the box is arranged in such a way that dehydration can occur evenly and simultaneously.

The liquid is sucked through the mass in the mold by means of suction chambers, which can be removed from the mass after the end of the liquid suction process. The molding box used, as well as the suction chambers, can be of any shape and be integral or detachable.

An essential part is the molding boxes, the walls of which, in whole or in part, are formed by the porous walls of the closed chamber, through which air is introduced into the molding box by sucking or forcing air through the raw material, which can help remove liquid from this material.

In FIG. 1 shows a sectional view of a molding box with one internal suction chamber; FIG. 2 - the same, in another embodiment, in a vertically longitudinal section; FIG. 3-

(295)

the same top view, and FIG. 4 - crate in a vertical cross section.

The proposed device for converting the agitated substances into a lumpy form consists of molding boxes / 7 and a suction box 7, with porous walls serving to restrict the molding box to the outside. The bottom} 0 of the mold box is formed by a stand on which the mold parts are to be further processed. Along the center line of the molding box, a chamber 5 is provided with porous walls, connected to the front walls of the molding box freely or rigidly. The chamber is equipped with a tube S for gas supply, and a suction box with a tube 3 for connecting with a vacuum.

The boiled mass is loaded into the mold box, and the suction box is connected to a vacuum. The gas used for this is injected (at atmospheric or elevated pressure) into the porous chamber and flows through its walls, through a stirred up mass, into the suction box. As it flows, the gas entrains the particles of liquid, and the mass is dried, compressed, and gradually acquires the desired solid form. After removing the water.

the suction tube is turned off, and the suction boxes porous chambers are raised up (simultaneously or separately) so that the molded part remains free to lie on the stand.

In the embodiment shown in FIG. 2-4, the molding box has two spaces, each with its own nozzle for the passage of gas. The suction boxes / are connected to the front walls 2 of the device, through which the suction tubes 5 separate boxes come out, and pass into the collecting pipe 4. The gas-conducting porous chambers 5 are located along the inner walls of the facades moving along and resting on the y. of the projections 6 onto the frame 7. Through the projections are introduced into the chambers of the branch 8 from the main gas supply pipe 9.

The entire device can stand on a stand 10 used for this purpose or directly hang over it. Here is the case when the sides of the stand are bounded linearly. The holes (slits) that may form, due to poor adhesion between the lower edge of the walls and under the heading, are closed with flaps 7 /, which are spring-loaded to the frame 7 by means of a gear 12, 75, 14, 75, 16. The moldings are filled with a fine agitated mass. 77, bounded by the porous walls of the suction boxes and chambers, as well as by partitions 18 protruding from the sides of the chambers. Suction boxes are connected to the vacuum by means of pipes 4; at the same time, gas is supplied to the chambers through pipes 9. Porous walls are made at the upper part in such a way that, if desired, faster deactivation can be obtained at the top or bottom or at the same time throughout the entire cross section.

Under the action of reduced pressure, the gas penetrates from the chambers through the mass into the suction boxes, entrains the liquid particles, and the mass dries out. After suction, the vacuum lines are closed. The frame 7 is then lifted by chains 27, as indicated in FIG. 1, or in some other known manner.

The chambers (resting on the frame) are successively raised, the pressure of the spring 14 stops, the guide 75 reaches the stop 22, whereby the flap 77 rotates and finally the frame reaches the stop 23 rigidly connected to the device and the latter rises to the desired height above the formed material remaining on the stand.

The relative movement between the chambers and the rest of the device prevents the molded material from pestering the walls of the molding box. For this reason, the cross-sections of the suction drawers, chambers and partitions 18 decrease towards the bottom.

In order to avoid losses during the filling of the molding boxes, the fixed front walls 2 are elongated above the upper end of the suction boxes and chambers, and in the front walls the slots 26 are extended outward, through which the chambers with seals 27 that are rigidly connected to the chambers move. On the same basis, the outer walls 28 of both suction boxes are extended along the height of the front walls. Suction boxes and chambers can be moved in such a way that the chambers, if desired, are placed outside.

In order to avoid connections and disconnection of gas and vacuum collecting pipes. the latter are introduced through the gaskets 24 into the vessels 25 and can be moved along with the rest of the device.

The molding box can be arranged in such a way that its bottom consists of a rigidly fixed or removable part of a trolley or other conveyance means on which the piece (briquette) can be inserted after removal of individual parts of the mold box. sintering furnace or other device for further processing.

A closed space with porous walls through which air is injected or sucked from the material placed in the molding box can usually be arranged in this way.

that the lore walls stand vertically, with the air flowing through the material and from wall to wall in a horizontal or near horizontal direction, however, the molding boxes can be arranged in such a way that a closed space for supplying or sucking air is located under the molding box and forms with its upper porous wall, the bottom of the molding box. And in this case, the bottom of the molding box may consist of a rigidly mounted or removable part of the conveyor device.

The subject of the patent.
