DE3715054A1 - Double gritting plate - Google Patents

Abstract

To reduce the amount of gritting salt on the roads and hence to preserve the environment, the salt is moistened with calcium chloride brine and then applied in an up to 30% reduced amount. This "double gritting plate" is easy to fit to existing gritting machines at any time. The separate application of salt and brine, the mixing of which does not occur until in flight after leaving the "double gritting plate", prevents clumping and guarantees a uniform, firmly adhering grit.

Description

State of the art

The invention relates to salt shakers for winter use for smoothness control.

Salt shakers for winter or road service are already known and used for decades. Salt is currently being used and brine solid particles and liquid before the Aus mixed and spread out with rotating spreading disc scatters. The principle can be seen on the spreaders for winter service of the companies Weisser, Schmid etc.

Disadvantages of the current problem solving

By mixing, solid parts clump together before spreading chen and liquid.

This creates

• - an uneven spread
• - an uneven coverage
• - a sticking of the loading device
• - An uneconomical use of the grit

task

The invention is based on the object, the above mentioned disadvantages in the type of spreading term.  

solution

This goal is achieved by the spreading disc consists of two levels and by separate spreading of Solid particles and liquid on two spreading plates or a double spreading disc.

Embodiment

In the drawings, the subject of the invention is in one Embodiment shown in section.

The double spreading disc consists of two circular levels, a solid level ( 2 ) and a liquid level ( 3 ), which are separated by a separating tube ( 4 ). On the double litter plate, the liquid, for example brine, is brought through the hose ( 6 ) and the nozzle ( 7 ) inside the separating tube ( 4 ) to the liquid level ( 3 ) and the solids, for example salt, are passed through the chute ( 8 ) to the free one Surface ( 12 ) brought the solid level ( 2 ). The rotation of the double scattering plate about the axis (10) (5) are thrown through the solid slats (9) and the liquid lamellae, the solids and liquids to the outside where they are after leaving the liquid level (3) and the solid layer (2) without Mix lump formation. By sloping the solids lamellae ( 9 ), the discharge rate of the solids is reduced. Through the end wire ( 11 ) at the end of the liquid level ( 3 ) the trajectory of the liquid is broadened. To improve stability, the liquid level ( 3 ) and solid level ( 2 ) are connected to one another via the separating tube and the liquid fins ( 5 ).

Due to the separate discharge of solids e.g. Salt and Liquid e.g. Brine on separate levels only comes through the intersection of the two trajectories to the mixture.  

This has the following advantages

• - no clumping of the spread
• - No spreading device sticking
• - uniform spreading
• - uniform coverage
• - economic exploitation
