  • the device according to the invention, the system according to the invention and the method according to the invention are particularly suitable for admixing a first substance and a second substance to a urea melt, a dispersion then being formed from the first substance, the second substance and the urea melt. This dispersion can then be processed into pastilles in the plant according to the invention.
  • the invention is therefore particularly suitable for producing a fertilizer that is easy to handle, in particular urea fertilizer.
  • a device for admixing at least a first substance and a second substance to a base substance for the continuous formation of a mixture is known.
  • the device has a first mixing container and a second mixing container.
  • the first and second mixing containers each have an inlet opening, an introduction opening for admixing the first or second substance, and an outlet opening.
  • the first and the second mixing tank are each provided with an agitator.
  • the outlet opening of the first mixing container and the inlet opening of the second mixing container are connected to one another by means of a connecting line, the connecting line being open during mixing operation of the device.
  • the mixing containers of the device should be operated with the exclusion of air. Since the system works with the exclusion of air and the components to be emulsified are continuously introduced into the mixing device, the components located in the mixing device are continuously transported away in the direction of the discharge line.
  • a device for admixing at least a first substance and a second substance to a flowable base substance has two mixing containers connected in series, each with an agitator.
  • a return line is provided to return fluid from the second tank to the first tank.
  • a device for admixing at least a first substance and a second substance to a flowable base substance has a first mixing tank and a second mixing tank, each of the mixing tanks being provided with an agitator.
  • a mixture is mixed in either the first mixing tank and the second mixing tank and then transported via a discharge line to a downstream processor. While one of the containers is being emptied, another container is being loaded or is on hold. The transport of fluid from the first mixing container into the second mixing container is not provided.
  • the aim of the invention is to improve the production of mixtures from a first substance, a second substance and a base substance.
  • a device for admixing a first substance and a second substance to a base substance to form a mixture in particular for admixing a first substance and a second substance to a urea melt to form a dispersion according to claim 1, is provided for this purpose, the device for admixing the following features
  • the admixing device has a first mixing container and a second mixing container.
  • the first and second mixing containers each have an inlet opening for admitting a base material or an intermediate mixture, an outlet opening for letting out the intermediate mixture or the mixture, an inlet opening for admixing the first or second substance and a pressure equalization opening.
  • the pressure equalization openings of the first and second mixing containers are connected to one another by means of a pressure equalization line, with the pressure equalization openings being above the fluid levels present in the mixing containers when the device is in operation when the device is in operation, so that the interior of the first mixing container and the interior of the second mixing container the same pressure is present, and the outlet opening of the first mixing tank and the inlet opening of the second mixing tank are connected to one another by means of a connecting line, which enables flow during operation of the device, with the outlet opening of the first mixing tank, the connecting line and the inlet opening of the second mixing tank being connected during operation of the device Mixing tanks are below the fluid level in the mixing tanks, so that fluid can pass from the first mixing tank into the second mixing tank.
  • a first and a second mixing container are provided in the device according to the invention and fluid can flow from the first mixing container into the second mixing container through the connecting line, which is open during operation, an intermediate mixing stage is thus produced in the first mixing container and this intermediate mixing stage is then fed to the second mixing container , where a second substance is then added.
  • This achieves particularly good and rapid mixing of the first substance with the base substance and then subsequently of the second substance with the intermediate mixing stage.
  • the multi-stage admixing prevents the admixed substances from influencing one another and/or the admixing of the at least one further substance is facilitated.
  • the mixing intermediate stage gets from the first mixing container into the second mixing container only by gravity, it can be ensured that a mixing time in the first mixing container is long enough to achieve a particularly uniform mixture between the first substance and the base substance. A sufficiently long mixing time to produce a particularly uniform mixture can also be achieved in the second mixing container. Due to the connecting line, which is open during operation of the device and lies below the fluid level, the fluid levels in the two mixing containers are always essentially at the same level. If, for example, the fluid level in the second mixing tank is higher than in the first mixing tank, then fluid can also reach the first mixing tank through the connecting line from the second mixing tank. As a rule, however, the intermediate mixture stage produced in the first mixing container flows through the connecting line into the second mixing container as a result of gravity. Continuous mixing operation is possible with the device according to the invention.
  • the mixing containers and/or agitators can be designed differently.
  • the first mixing container and the second mixing container each have an essentially the same basic shape with essentially the same volume, and the first mixing container and the second mixing container are arranged essentially at the same height.

  • Fluid thus emerges from the inlet openings perpendicularly to the central longitudinal axis of the containers and also enters the outlet openings again perpendicularly to the central longitudinal axis of the containers.
  • the inlet openings can, for example, also be aligned in such a way that they support a flow movement within the mixing container around the central longitudinal axis.
  • it can also be useful to direct the inlet openings against the flow generated by the agitator and also to align the outlet openings against the flow generated in the container by the agitator.
  • the inlet into the second mixing container is preferably in the direction of flow.
  • the angled pipe sections can also be left out at the outlet openings.

  • melts in particular can be mixed and then pelletized.
  • the system according to the invention is particularly suitable for pastillating a urea melt, a first substance and a second substance being admixed to the urea melt. This is of great advantage, especially in the production of fertilizers.
  • the melt Inside the mixing container, the melt can be kept in a good flowable state, so that a very even mixture can be produced with the two substances supplied.
  • the mixture of the melt and the at least two admixed substances is then fed to the pastillation device.
