DE1068670B - Device for mixing powdery or granular. Good with thick liquids - Google Patents

Description

The invention relates to a device for 'mixing of powdery or fine-grained material with viscous liquids.

In such devices, it is known to throw the material inside a container by means of a rotating spreader plate to the outside and the liquid from the inside by means of a misting body in the direction of the material. The liquid the powder is added in its entire thickness, so ¹ that the mixture adheres to the wall and has to be replaced by a fixed stripper from the circumferential wall. The detached smaller and larger lumps and crusts then get into the mixing trough, where one must try to produce a uniform mass from powder, lumps and crusts. It is also known to throw a liquid from the inside onto a freely falling jacket-shaped stream of granular material. The liquid beats through the dry material veil, so that lumps and crusts are again obtained on the vessel wall behind the jacket.

In order to avoid this formation of lumps and crusts, the spreading plate according to the invention is sufficient so close to the container wall and revolves at such a high speed that the liquid droplets hit the Hit the inside of a closed veil of material trickling down the wall without breaking through it.

The use of a height-adjustable funnel that supports the container wall is particularly advantageous surrounds above the spreading plate and creates an annular gap with the spreading plate, which regulates of the dry goods curtain.

In the drawing, an exemplary embodiment for the subject matter of the invention is shown schematically in the axial direction Section shown.

A stationary hollow axle 1 is used to supply the liquid to be sprayed or nebulized. This hollow axle carries a bearing sleeve that can be set in circulation by means of a belt drive via ball bearings 2, which carries the spreading plate 3 below. This arrangement is at a distance from a glass cylinder 4 enclosed, which serves as a container wall and enables observation of the operation. The one in the upper, horizontal end wall provided sliding surfaces lead the powdery or granular Good to the loyalty plate 3. With its edge, the edge forms a height-adjustable funnel-shaped Guide ring 5 an annular gap, the outlet of the device for mixing

of powdery or granular material

with viscous liquids

Good regulates and makes it even. Under the high-speed spreading disc 3, on which e.g. two different substances fed in via the two chutes shown are mixed a conical, upwardly open nebulization body 6, which rotates over the hollow core 7 is connected to the bearing sleeve 2. Numerous tangential nozzles 8 in this hollow core fling the Liquid from, generate a negative pressure inside the same and suck liquid through the hollow shaft after.

Claims (2)

Patent claims: 1. Device for mixing powdery or fine-grained material with tough ones Liquids, in which the material is replenished within a container by means of a rotating spreading plate thrown outside and the liquid from the inside by means of a nebulizer in the direction of the material is thrown, characterized in that the spreading plate is so close to the container wall enough and revolves at such a high speed that the liquid droplets on the inside hit a closed veil of material trickling down on the wall without breaking through it. 2. Device according to claim 1, characterized by the arrangement of a height-adjustable, the hopper wall above the spreader plate surrounding the hopper. Considered publications:
