Description

Description

The invention relates to an arrangement for continuous Treatment of bulk goods in several physical and / or chemical treatment stages.

To bulk goods of certain chemical composition and physical To maintain consistency, given raw materials often have to be subjected to several successive treatments: Drying by heating or blowing with hot air, conversion by heat alone or by mixing with other solid materials, liquid or gaseous substances, where heat has to be supplied or heat can arise that has to be removed, among others. The treatment may require the use of explosive or toxic substances or gases or these may be released during the reaction.

The following are known for carrying out the treatments mentioned: rotary kilns, in which the problem of tightness causes considerable and costly problems, stirred tanks in which the sufficient Mixing takes a long time and is difficult to monitor, and vibrating, housed in cylinder-like vessels Spiral conveyors that can only be produced for small quantities and in which the individual treatment zones are not sufficiently spaced apart are detachable. In the latter case, in particular, since there is only one drive, there is only one for all treatments single oscillation frequency and single amplitude possible, so that an adaptation to the changes during the treatment Flow properties of the bulk material can not be made.

The object of the present invention is to enable a continuous multistage bulk material treatment, with the individual Treatment zones are easily separable from one another and the throughput speed of the respective consistency of the bulk material is optimally adaptable.

The object is achieved by an arrangement according to patent claim.

An exemplary embodiment of the invention, further refinements and the mode of operation are illustrated with the aid of the attached drawing explained.

Fig. 1 shows the side view of an arbitrarily extendable row vibratory conveyors containing individual treatment steps,

Fig. 2 shows the section through a particularly for a heat treatment vibratory conveyor determined for the bulk material.

Each vibratory conveyor 1, which is resilient in a known and customary manner Is mounted on a stationary support frame, is by its own oscillating drive 2, which is an oscillating magnet or a Can be unbalanced drive, according to the following from the currently existing consistency of the bulk material in terms of conveying properties individually driven on frequency and / or amplitude of the oscillation. So that the deviating oscillating movements of the one behind the other vibratory conveyor 1 lying in the treatment sequence do not interfere with each other, are the successive vibratory feeders 1 via elastic, movement-compensating sealing sleeves 3 connected to each other.

Each individual vibratory conveyor 1 is therefore its own special one Treatment stage of the bulk material assigned, for which he accordingly is equipped. A heat treatment stage is exemplified below overdone.

The trough of the vibratory conveyor is raised by a stationary, thus closed cover 6 that does not resonate and rests on a frame 4 running around the circumference. The conclusion of the Treatment room to the outside and the compensation of the oscillating movement is carried out by a circumferential, elastic, if necessary heat-resistant and gas-tight sealing sleeve 5 »which in certain Execution fabric compensator is called. To make the interior accessible To do this, the cover 6 is expediently fastened to hinges on one side and designed to be hinged. In the present

Example is the cover itself pendulum or pivotable on the central suspension l6 on a vibrating conveyor 1 spanning Traverse suspended, which in turn hinges on one side 7 is attached and hinged. The wraparound, heat-resistant Seal 19 seals the interior when the lid is pressed on. Elongated holes compensating for the different thermal expansions and gap is a support plate 17 on the cover for holding the heating elements 8 appended. This support plate 17 is expediently designed at the same time as a reflector for / uie thermal radiation. Of course, the radiators can be switched individually or in groups as heating zones 9 as required.

For observing and monitoring the reaction process in the vibratory conveyor 1, nozzles 13 with sight glasses 10, which are inclined towards the edge, are expediently arranged in the cover 6. As a die It is known and cannot be avoided if reflections impairing vision when shining and seeing through the same sight glass It is common to arrange two separate light corridors, either through two connecting pieces lying next to each other or two sight glasses in one connecting piece. As a simplifying improvement, it is proposed that a blackened partition wall be placed in the connecting piece directly below the sight glass 10 diametrically to switch off the visually impairing reflection when shining in.

For monitoring the temperature and also for direct control or control, 1 thermal sensor can be installed in the bottom of the vibratory conveyor l8 should be provided.

To protect the vibratory conveyor against overheating and / or for process control, 1 mouth nozzle lk of blowers 20 can be arranged under the bottom of the vibratory conveyor, which for example correspond to suction nozzle 15 on the top.

individually / adjustable
As a result of the vibration-induced movement of the bulk material, not only the advancement speed adapted to the respective treatment process takes place, but also, in particular, constant circulation and mixing, if necessary with gaseous, liquid or solid additives, with warming or cooling air or gas, e.g. B. protective gas, as well as a uniform rapid distribution of heat.

If as a result of heating or an exothermic chemical reaction the channel of the vibration conveyor I is heated strongly, experience the channel and its fastening parts, in particular the vibrator drive load-bearing connection block (l ') different thermal expansions. To take account of these heat movements, it is It is advisable to create a fixed connection only at one point of the longitudinal extension and only shift it in the other areas. lent clamps to be provided.
