Description

one

The invention relates to the treatment of material with pressure, in particular to drum presses for pressing bones.

The well-known drum press for squeezing liquids from loose vegetable and mineral products® contains a rotatable outer perforated drum and an inner perforated inside it.

Shrinking the release of liquid in a thick layer leads to a low 4% degree from. zhati N vzvkoy performance.

The purpose of the invention is the production of the body of the press and the degree of pressing liquid.

This is achieved by the fact that the internal drum is made in the form of cylindrical shell A with double walls, the ring-shaped space between the shafts is divided by rectilinear for the directional movement of the heating body, and along the ends of the outer drum are filled with the BS.

On 1G. 1 shows a press, a general view; in fig. 2 is a section along A-A in FIG. one; on; fet. 3 - press, top view; in fig. 4 heat transfer circuit ..

The continuous drum npedc for annealing a liquid consists of the outer surface of the IR (this slave 1 with its sides on both ends, inside which are drum 2 and screws 3, 4, which serve to feed and discharge material.

By the two supporting bands, the drum 1: is erased into three pairs of rollers 5; YcTaHOitonnyh on the base plate, and with the help of a circular crown and a combination of drive gears 6 is rotated.

Drum 2 is eccentrically placed in the space of Barkan 1, it is produced; it is in the form of Yu (a livdrich shell with door machines. The space between the outer and inner walls of the shell is divided by the first, townships 7.

The heating fluid (condensate) is supplied to the pipe S, and the heatsinks are supplied to the pipes (a sting and through a stationary-mounted box).

Direction vrashen drums one thing. The number of turnover under} is eobno in such a way that MH equals the surrounding JHbix velocity on the inner and outer surfaces of the drums. At the exit of the pressed material, the brushes 9 and the partitions 10, separating the material from the drum, are installed ... I The press works as follows. I A material containing a liquid in the izlischka, such as beet pulp sugar beet pulp, screw 3 through a longitudinal cut in the lower part of its body under a certain pressure is fed into the sickle (space of the right side of the press (Fig. 2). Since both walls of the sickle move in clockwise the arrow with one New district speed, each separate piece of material moves down without sliding, gradually (thickness. Since the width of the pressing chamber is delimited by the sides and constant: in size, then the decrease in the layer thickness Reduces its volume and, at the same time, squeezes out the liquid that is discharged through the hole in the drum; 1; The thickness of the layer jt can be made to be very small, i.e., the press device allows you to carry out the process of squeezing out the liquid in a thin layer. material is realized by supplying a heating fluid (condensate) to the inner drum, which ensures: advantageous temperature conditions of the process, as well as creates favorable conditions for squeezing the liquid, since the direction of heat flow m drainage fluid .; The pressed product passes into the left cavity and with the help of a rotating brush and a spindle, the rod moves away from the sieve surface; the drum 1 is guided into the screws 4 and is removed from the press. Formulas a and 3 about b e e e and a drum press for squeezing liquids from loose plant and mineral products, containing a rotatable outer perforated drum and an inner one inside it, which is characterized by the fact that, in order to master the production of the press and degree wring out liquidoet, the inner drum is made in the form. cylindrical shell with double walls, the space between which is connected to the coolant supply system and divided by partitions of directional motion, and the sides of the outer drum are made on the end surfaces of the outer drum
