APPARATUS FUR Application August In Germany '3 Claims. (01!. 71-4) In the chambers shown in Figs; 1-3, the sta- This invention relates to apparatus for the manufacture of superphosphate and the like products.

The chief cause of =the defects of the superphosphate reaction chambers hitherto generally employed, resides in the intermittent manner in which they operate.

The present invention aims at providing reaction chambers which are adapted to enable the my work to be carried on continuously, in that the reaction mass and the support on which it rests and adheres is moved in relation to that part of the chamber which contains the intake (mixing machine) and the discharge device, so that the dissociated portions of the charge canbe conveyed continuously to the discharging device and fresh raw'material can be fed into the vacant portion of the chamber.

In-the embodiments illustrated in the accomgg panying drawing, these parts rotate on a horizontal axis.

As the apparatus rotates on a horizontal axis, the stationary hollow cylinder b prevents the liquid superphosphate from spreading towards The drum 0 and reaction mass rotate on the horizontal rotational axis y--@:-and

accordingly, the mixer 'm and discharging device I of the knife the latter "material and detaches dislodged material falls through are stationary whilst the other parts and walls can be connected either to the stationary or the 3p rotary systems, as may be most convenient. The hollow cylinder is providedwith ,an opening of ample dimensions, extending from near the one end wall a to the other end wall a and from the auxiliary wall a to about a line under the knives 5 14. Through this opening the dislodged material passes into the hollow cylinder, from which it is led into the open by means of any convenient conveyor. The auxiliary wall a is connected with the hollow cylinder and merely serves as a boun- 449 dary for the dissociation chamber, so that the gases liberated by the dissociation process can be evacuated.

In order to make clear the character of my invention, a preferred embodiment is illustrated in the drawing wherein:

February 2!, 1929 of an end wall a in which is placed a hollow cylinder b, concentric with the rotational axis. The end wall a (in which is sunk the mixer m) and the hollow cylinder in are held in place by an iron structure. The opposite end wall a is connected with the cylindrical shell 0, with which it turns in the direction of the arrow s. The cylinder, which is mounted on rollers r,

is driven, in the usual manner, by a pinion '1 with driving wheel 2 The contact surfaces between I a, and c, and also between'a and b, are self tightening. The auxiliary wall a is disposed vertically and tangentially in relation to the hollow cylinder b. It carries the exhaust gas flue l, which passes out of the chamber through a and is connected with a fan. The discharging device consists of the knife 14,

which is disposed at right angles to the rotational axis and is reciprocated in the direction of the double arrow s", by means of the guide rods 15 which slide in the bearing 16 and are moved by a crank or the like. a is provided with a slot through which the knife 14 passes out of the interior of the chamber and is thus detached from the block of material. While the knife is in this position the cylinder 0 is moved forward so that, in the next forward movement encounters a thin layer of it from the block. The

is covered by the mixer m which is thus disrelation to the block of mate- The end Walls a and a are connected to b, and are carried by an iron structure. The surfaces of contact with the cylinders c are close fitting. The cylinders c are mounted on rollers r, and are uniformly moved by means of the toothed crowns z. The discharging device consists of a number of knives 14, which are attached to two endless chains 17.

These chains, together with the knives, are moved' by a toothed wheel not illustrated in the direction of the arrow s pass out of the chamber through a slot in a, are diverted from this direction of movement by rollers not shown and passed round the outside of the chamber, to be led over other rollers and into the chamber again through a slot in (1 This arrangement of the discharging device enables the two cylinders c to be moved in a uniform manner. The dislodged material drops through the opening provided in the hollow cylinder b and on to the conveyor 23.

Instead of being vertically disposed, as shown, the knives may also be arranged parallel with the rotational axis yy. The embodiment shown in Figs. 1-3 would be provided with a knife, clamped on one side in a sliding shoe and swinging up and down in a guide track provided in a. In the ex-.

ample shown in Fig. 5, a number of knives, attached to two endless chains, would be provided. These chains would run at right angles to the rotational axis and guided, in each case, by two rollers mounted in the end walls a and a respectively.

In the embodiment according to Fig. 5, the

parts a, c and a as a whole, assume approximately a spherical form. The end wall a is connected to the stationary hollow cylinder b, and

carries the mixer m. a and c constitute a unit,,

are mounted on rollers 1', and are rotated by means of the toothed crown z. The block is broken down by'means of the knife 14 which rocks on the shaft 13 driven by a crank or the like. The reaction mass is moved forward intermittently, and at the moment when the knife 14 is inside the cylinder 1). .The dislodged material is carried away by the conveyor 23. The contact surfaces between a and c, and between a and b, are self-tightening. Z is the gas exhaust flue.

The reaction chamber shown in Fig. 6 is in the form of a ring of circular cross section. The stationary cylinder is connected to the end wall a, and the rotary support 0 is connected to the end wall a The block is broken down by means of a revolving knife disc 14, driven by the pair of pinions 7c and :i. The toothed crown 2 serves to drive the support 0, and the conveyor 23 to remove the dislodged material. I is the gas .exhaust flue.
