Definitions
- the invention relates to a device for drying bulk goods with a at least partially funnel-shaped container according to the preamble of the claim 1.
- the invention according to claim 8 relates to a Bulk dryer that uses a dehumidifier for that has upcoming dry grass.
- Drying devices for drying bulk goods such as B. plastic granules are known, inter alia, from DE 3234431 C2.
- the one to be dried Granulate is in a container that is down for granule removal tapered towards the funnel and charged with the granulate from above becomes.
- a dry gas is warmed air in particular, which contains the moisture adhering to the granulate sweeps away.
- the drying air previously passed through a dehumidifier.
- the dryers are generally for a certain throughput designed for bulk goods.
- the plastic granulate is after the Drying supplied in particular plastic processing machines. Before they are often mixed with other components that are essential represent a lower percentage in the desired raw material.
- Conventional dryers are used for the pretreatment of additional granules very small amounts are only of limited use. Will this Problems with the drying result may not be completely filled of the granules occur because the passage of the dry air is no longer in takes place homogeneously. On the other hand, the dryer is full with granules due to the time-dependent thermal degradation of the bulk material not possible. The drying system can therefore be in its capacity do not adjust the desired amount of dry granules.
- the dehumidifier remains largely when the drying capacity is reduced unused because it should be designed for the case of system utilization got to.
- Regenerable cartridges are often used to dehumidify the dry air with moisture-absorbing substances used as additional Unit are assigned to the granule dryers.
- the object of the invention is a drying device for bulk goods to create, which optimally adjusts to the amount of granules to be dried can adapt, is particularly suitable for small amounts of dry, and a high flexibility in use, especially with regard to different locations, having.
- claim 1 claimed a granulate container with adjustable walls. Furthermore, claimed a drying device according to claim 7, which a membrane dryer has as a dehumidifier.
- the drying device has a funnel-shaped container in which the bulk material to be dried is filled and removed can. Furthermore, the passage of a dry gas through the container possible in such a way that the dry air flows through the bulk material.
- the container is characterized by a funnel wall, which is at least partially can be adjusted in inclination, whereby the volume of the container can be changed is. This makes it possible to move the container to the desired one adjust the amount of dry bulk material. This can either be done manually, or done automatically by a suitable adjusting device.
- the emptying behavior can be adjusted by adjusting the funnel inclination of the container are positively influenced.
- the tank is low there is a larger hopper slope inside the container.
- the stronger one The hopper slope is the same for small dry quantities when emptying the container the absence of the granulate load in the upper area of the container, which in the case of large quantities of bulk material, the granules are removed from the container presses.
- the inclination adjustment of the funnel walls is simultaneous the container volume is reduced.
- the lower amount of bulk material is therefore reached the same or only slightly lower level in the container, as with full utilization of the plant. This ensures that the dry air Even when the volume throughput is reduced, the granulate is even flows through, and takes a path of defined length through the granules.
- the inclination and volume of the container Wall parts of the funnel wall can be adjustable. It can be adjustable and Fixed, essentially rigid wall parts are used which form the funnel through their interaction. But it is also conceivable to manufacture the funnel from an elastic material, where volume and Inclination of the funnel is caused by an elastic deformation of the funnel.
- An advantageous embodiment of the funnel provides that it consists of several build up flat surfaces. At least one of these is said to be adjustable Form the side of the funnel, so that this ensures the adjustability of the funnel becomes.
- Appropriate training of this variant is achieved by providing a pyramid-shaped funnel with four faces. Two yourself opposite funnel surfaces are stationary, the other two as adjustable sides are executed. This keeps the expense of components for the Bulk container within limits and at the same time offers the possibility of reducing the hopper volume and the inclination of a sufficient part of the funnel wall adjust the bulk quantity.
- the fixed wall parts can be steeper be carried out as the adjustment sides in the position of the largest container capacity. As a result, an optimal one can be achieved even when the container is low Emptying behavior can be achieved.
- the fixed wall parts of the Funnels can also be at least partially vertical.
- the Adjustment sides pivoted in the area of the outlet opening.
- Swiveling the adjustment sides is the same with this design Size of the outlet opening, the inclination of the container walls and the volume of the container affected.
- the fixings for the adjustment sides in different Tilt angles can e.g. B. attached to the fixed wall parts his.
- Adjustment sides with an essentially trapezoidal shape. Will this be in their inclination is adjusted, so for the side edges of the adjustment sides in the horizontal projection seen parallel to the fixed wall parts a different slope.
- This can be compensated that the fixed wall parts of the container with one over the adjustment range of the adjustment sides changing inclination are executed. Thereby is achieved that a constant over the adjustment range of the adjustment sides Gap between the outer edges of the adjustment sides and the fixed Side parts can be adhered to. Additional sealants such as B. This eliminates the need for rubber lips on the edges of the adjustment sides.
- a maintenance opening can be arranged in one of the fixed side walls his. The easiest way to achieve this is when this wall part is vertical is executed.
- the maintenance opening enables z.
- the container can advantageously be double-walled, whereby the dry air is passed through the cavity thus formed before it Bulk material reached. This can reduce the temperature loss in the container be reduced, which reduces the need for heating energy. This measure is due to the low bulk quantity with an unfavorable ratio of Volume to surface makes sense.
