Definitions
- the invention relates to a dissolving system for granular material, in particular for minerals with soft components such as clay and / or clay, bulbous mineral conglomerates or the like.
- the dissolving system has a trough with an inlet and with an outlet for the material that is between the inlet and Outlet is conveyed through the trough.
- a shaft driven in rotation and equipped with tools Arranged in the longitudinal axis of the trough is a shaft driven in rotation and equipped with tools.
- the tools have a wedging active surface, between which and the trough wall or a tank formed on them by firing, there is a wedge gap that narrows in the direction of rotation of the shaft from front to back.
- washing tools that have a trapezoidal profile with a flat bottom.
- the latter includes a wedge angle with the trough circumference in order to bring about a strong wedging effect on the goods. This results in a high pressure build-up and a strong squeezing, grinding and dissolving effect on the material to be treated.
- the shape of the trough is basically not critical either, since the trough melts itself together during operation. This means that a tank forms on the trough wall that adheres to it, which extends in the circumferential direction of the shaft and a working gap remains between the and the wedging tools. It is desirable to tamper with the trough, as this counteracts wear.
- the pressure build-up mentioned takes place between the bottom of the trapezoidal profile of the wedging tools and the tank formed on the trough wall due to the jamming.
- the side cheeks of the trapezoidal profile have the function of holding the item to be treated, ie preventing the item from flowing away to the side.
- the object of the invention is to provide a dissolving plant of the type mentioned with an improved dissolving effect.
- the wedging effective surface of the tools is convexly curved.
- the curved effective surface of the wedging tools takes into account the rounding of the casing of the trough or the rounding of the shell formed by the tampering therein. An even stronger wedge effect with higher pressure build-up and a correspondingly improved dissolving effect are achieved in this way. Different types of goods to be treated can be taken into account by a different convex curvature of the active surface.
- the tools are provided with identical or identical wear sets in the area of the active surface.
- the latter are positively supported on the tool in order to apply force in the direction of rotation.
- the active surface is structured in a manner that retains the material to be treated. This counteracts tool wear. However, massive tampering with the tools could have an adverse effect on their release effect. In principle, the convex curvature of the tool effective surface ensures that the material flows away well.
- the active surface is provided with parallel grooves which extend in the longitudinal direction of the shaft.
- the grooves have a rectangular U-profile.
- the active surface is reinforced with ceramic or hard metal. Wear is counteracted and a long service life is achieved.
- the active surface is formed on the rear edge of the tool in the direction of rotation by a ceramic or hard metal part. At this point the wedge gap is narrowest, the pressure build-up is highest and the wear is most serious.
- the tools have cheeks protruding from the edge of the active surface on both sides. These serve to record the goods to be treated, i.e. H. to prevent the material from flowing away to the side.
- the cheeks diverge outwards. They form a trapezoidal profile with the active surface.
- the outer edges of the cheeks are rounded so that they essentially follow the curvature of the wall of the trough or the curvature of a tank formed in it by fusing. This ensures a good lateral seal.
- the tools in the area of the active surface are mirror-symmetrical and suitable for rotation in both directions. After a certain degree of wear has been reached, this enables the tool to be turned through 180 ° and thus better utilization of the tool.
- the tools are equipped with carriers.
- the latter can have an angled profile open at the front in the direction of rotation of the washing shaft or a concave curved hollow profile. The drivers serve to convey excess goods over the apex of the shaft to the beginning of the wedge path.
- the trough is segmented in its base area with bulkhead plates, between which the tools work.
- the bulkhead plates serve to hold the material to be treated, i.e. H. to prevent the material from flowing away to the side.
- the subject of the invention is not only the complete opening system, but also each wedging tool for this.
- each wedging tool for this With regard to the attachment of the tools to the shaft, reference can be made to EP 0 712 665 AI.
- the wedging tools are particularly suitable for interacting with a trough narrowing, as described in DE 202 18 919.8 Ul.
- FIG. 4 shows the schematic side view of a first opening system with a trough and a shaft running therein, which is equipped with wedging tools of another type;
- FIG. 5 shows the front view of a wedging tool with a view in the direction “A” of FIG. 4;
- 6 to 8 show the schematic side views of a second, third and fourth opening system with further tool variants
- FIG. 9 is a front view of the fourth dissolving system shown in FIG. 8, looking in the direction IX;
- FIG. 10 shows the schematic side view of a fifth opening system with a further tool variant; and 11 and FIG. 12 further wedging tools of an opening system in a side view.
- trough bottom 10 is semi-cylindrical, in FIGS. 8 and 9 prismatic and in FIG. 10 rectangular.
- a shaft 14 is arranged in the cylinder axis of the trough and is equipped with wedging tools. With regard to their attachment, reference can be made to EP 0 712 665 AI.
- the dissolving systems are used to remove granular mineral goods from soft components adhering to them.
- the systems usually run wet.
- the trough is flowed through in the wavelength direction by the material to be treated and in countercurrent to it by water.
- water for washing the goods is not essential for the invention.
- dissolving systems run better dry.
- the trough of the dissolving plants firecracked in operation in a thickness that is indicated by line 16.
- the wedging tools according to FIGS. 1 to 3 and 8 to 10 enclose a wedge angle with the armor formed by the tampering, which narrows from the front to the rear in the direction of rotation of the shaft.
- the wedging active surface 18 of the tools is convexly curved. According to the curvature, the wedge gap narrows towards the rear in the direction of rotation.
- the effective surface 18 is provided in the direction of rotation of the shaft with parallel grooves 20 at the rear, which extend in the direction of the wavelength and have a rectangular u-profile.
- the Nu Ten 20 contain inserts 22 made of ceramic or hard metal, which are flush with the curvature of the active surface 18 and reinforce the latter. If the grooves 20 are left free, they become clogged during operation.
- the curved active surface 18 of the tool according to FIG. 2 is composed of three identical wear sets 24 which have grooves 20.
- the active surface 18 consists of two identical wear sets 26 without grooves.
- the wear sets 24, 26 are positively supported on the lugs 40 of the tool in the direction of rotation.
- the tools are equipped with drivers 28, 30 in the direction of rotation of the shaft at the front.
- the drivers 28 according to FIGS. 8 and 9 have an angular profile which is open at the front in the direction of rotation of the shaft.
- the trough is segmented in its base area with bulkhead plates 32, between which the wedging tools work.
