Description

Mixing equipment for the manufacture of compound feedingstuffs

The present invention relates to an apparatus for the preparation of a compound feed comprising several components, consisting of powdery and / or fine-grained / base materials and optionally porous liquids, e.g. Suitable for feeding liquid fat, molasses, dissolved urea, etc.

Currently, the production of compound feed is based on two technologies.

One method of production is continuous mixing and mixing, the other is batch / or batch, i.e. serving per portion, and then mixing.

Continuous power generation technologies, as is known, provide end products of sufficient quality only with sufficient capacity.

In small plants with a few to / h power, continuous space ^; dental measurements of the feed materials consisting of grain crops and fodder concentrate from the appropriate component cells. Dispensing devices are usually variable speed delivery screws. The mixing of the feed components is provided by a hammer grinder, on the one hand, and by a pneumatic material conveyor following the grinder, on the other hand. Many types of commonly known Skjold equipment are subject to this.

For granular products / feed grain / volume by volume / hl. weight / variable, impurities in the crop, different grain sizes of different batches, ϊ all have a major influence on the volume composition of pon-1180226 by volume. Λ cono concentrates, for the ownership of poor rivers of dull materials; the inclination to arch is also detrimental to the accuracy of volume measurement.

The raw materials entering the grinder do not always mix in the pneumatic transport line. For example, the airflow causes smaller, lighter particles of the mixture to move faster, and you can only carry larger, heavier particles more slowly. This leads to some sorting which adversely affects homogeneity because the concentrate particles, including the high performance premix particles, are smaller and, among the lighter ones, increase the inhomogeneity during the pneumatic delivery.

Thus, the quality of feeds produced by continuous volume measurement and continuous mixing is not, as can be seen, the most advantageous, which can also have adverse consequences during use / over-feeding. This circumstance is of special importance for small animals / e.g. poultry / as well as in the feeding of the growing potato curse.

The listed faults and shortcomings of continuous power generation can be eliminated and avoided by the batch / batch / per-feed / compound feed production method. Bz, the manufacture of compound feed presupposes a preliminary and accurate comparison, and the use of a convenient mixing machine results in a proper homogenous mixture.

Such feeds can also meet the stricter requirements of livestock professionals for the quality of feed for small and small animals.

Batch feeding produces a finished product with high quality characteristics, but requires more sophisticated technological equipment.

More sophisticated mixing plant equipment requires more machines, larger structural dimensions, more building levels and consequently more building space. Ultimately, this means more investment.

Due to the higher cost of the facility, smaller farms are unable to create the conditions for economical and high quality feed production and to produce compound feed with their own equipment. Farms therefore transport the highest proportion (70-90%) of the nutrients to the distant agitator and then return it as ready-to-eat food. Thus, 70-90% of the total material can be significant in loading, freight.

In practice, batch mixing plants using batch / batch / technology are generally designed as follows.

Component and finished goods / ready-to-eat / tanks or groups of tanks are located on the upper level (or several upper levels) of the factory building. Dispensing machines are connected to the underside of these, the outlet. Below the bellows, a balancing tank is installed on the floor, into which the dosing machines fill the components and raw materials that have been removed from the component cells.

In the technological order, the agitator following the balance is placed on the building level below the balance. If you move elsewhere, for example. for the higher floor of the plant, even if at the same level as the balance, a linkage between the balance and the mixing machine must be provided with a material handling machine. Usually you need to insert a buffer-tar-2180226 plate and of course some valves, level gauges and other fittings and appliances should not be left out.

Electrical / _f electrical / possibly pneumatic / automation systems to protect technological equipment and prevent malfunctions should also be expanded.

From the mixer, the homogenized material is fed into another feed system into the feed cells / tanks / or into the feed granulation / pelletizer / machine group.

It is well known in the art of mixing equipment that installation in multi-storey, high-rise buildings is a tower-like solution. Thus, from a traditional technological point of view, the ideal solution seems to be expensive.

SUMMARY OF THE INVENTION The object of the present invention is to eliminate the drawbacks and to provide a mixing device which is free of the above-mentioned disadvantages.

The invention is based on the recognition that the comparator. the mixing and component cells and dispensing conveyors can be assembled and combined into one unit. As a result, the material dosing of the component components containing the nutrient component can be carried out in the immediate vicinity of the floor level of a single-storey / one-story / factory building.

The present invention relates to a mixing device for producing compound feed. to which the grinding equipment belongs and its units are arranged on a single functional level. The silos for storing the nutrient components are connected to a balancing machine, preferably a twin screw mixer or a tapered mixer. A temporary storage is provided between the balance and the bucket elevator. There are feed cells for storing the feed mixture, which have a feed carrier and feed conveyor. You have a skip or other bucket lift for loading the feed wagon.

Both the twin screw mixer and the conical mixer are equipped with separate feed screws and the mixer is connected to the silos.

The technological process depicted in Figure 1 illustrates a solution of the possible variants. The equipment, its nutritional production, is described below.

The grain products and other dung / flour / or granular raw materials poured into the hopper 1 pass through the pneumatic / air flow / conveyor belt 2 and the stone separator / heavy material selector 3 to the hammer grinder 4, which is integrated with a fan. When dispatching grain products and other materials with a larger particle size, the material is directed to the grinding chamber, where the necessary grinding takes place. There is no need for grinding when pouring fine-grained, deroed, floury materials. In this case, the swivel space can be bypassed and only a simple material handling operation is performed. Through the airstream pressure pipe 5 through the cyclone 6, then through the air damper 7, the conveyor 8 and the conveyor 9, the

-3180226 feeds material to one of 10 standing positions.

From the scissors, the dispensing machines 11 feed the weighed components one after the other to the twin screw mixer 1 on the balance 14 or to its screwing auger 25. After the stacked stack, the u.n. Microcomponents / additives can be delivered through the filling opening 12 to the balance 14 or to the twin screw mixer 12 where the feed is homogenized.

After completion of the mixing operation, the homogenized mixture is transferred to the temporary storage tank 15. From there, the feed mixture 16, the bucket elevator 17, the feed conveyor 18 and the feeders 19 can be transferred to one of the feed pellets 20 and stored until use.

When the feed wagon 24 is being filled, the feed carrier 21, through the squeegees 22, allows the feed wagon 24 into the feed opening of the feed wagon 24.

The number of silos / component cells / 10 and the number of feed cells 20 are adapted to the need. The feed conveyor 23 may also supply glove feed to the elevator foot 26 if the need arises for some reason,

The technology may be complemented by a granulating / palletizing device known per se and / or by incorporating a liquid component.

The balance 14 is equipped with a twin screw mixer 13.

The 13 twin screw mixer has 25 feeder screws, which can be omitted for a small number of component cells.

Figures 5 and 6 show in balance two views of the balance 14 with a taper mixer 28 and a planetary screw 27. The cone mixer 28 is carried by the conveyor 25 or other conveyor.

The hopper 1 is located outside the wall of the plant building. The hammer grinder 4 and the hopper 1 are connected by a pneumatic conveyor tube 2 with the stone separator 3 interposed. The 10 silo / component cell / group is located on the floor of the plant building. Dispensing machines 11 are connected to the cell outlet arrows. They are carried on the twin-screw mixing machine 13 and its projecting feed screws 25. The 12 twin screw mixer and the bottom 14 scales are above a shaft. In the shaft are mounted the legs 26 of the bucket elevator 17, the temporary storage 15 and the carrier 16. The power cells 20 are also located on the building floor.

The feed outlets 21 are secured to the outlets of the feed cells 20. The feed conveyor 22 fills the feed conveyor 24, which may optionally be loaded with a bucket elevator 17.

Cyclone 6 sits on top of the silos 10, with the bottom connected to the air lock 7. The conveyor 8 is coupled to the cells 10 and the carriers 9.

The bucket elevator 17 serves to charge the feed cells 20 through the elevator foot 26. The feeders 20 feed the material into the feed cells 20. When unloaded, feeder 21 passes through feeder 22 to finished feed cart 24.

According to the invention, the operation of the mixing device is as follows, the additives are weighed instead of the usual weighing tank. The component feed to the mixer is loaded and fed into the short feeder conveyor / conveyor which is part of the mixer. Depending on the number of component tanks, the mixer may be equipped with several conveyor screws. They can also be fed directly to the mixing machine.

-4180226

The mixer built on the scale also functions as a weighing tank.

Dispensers mounted on the knockout opening of the component cells are fed to a mixer and its feeder located near the attic of the building. The latter are connected to the agitator feeder auger by means of suitable carrying pieces, so that they cannot cause inaccurate weighing. The mixing of the components begins as soon as they enter the mixing space of the mixer. The components measured in succession are thus introduced into a premixer with a continuous flow. Component cell outlets and outlet outlets are also low relative to the floor slab of the build. As a result, the building may have a single-storey and moderate interior height.

The scale-mounted / on-scale / mixer can be of any type or design, or operate on any principle.

Preferably low-build machines, e.g. two turtles / two parallel horizontal twin screws / mixers. The shafts of the mixing augers of the invention / twin rotor / mixer can be extended, provided with a feed auger which extends below the dispensers of the component cells and thus feeds the feed mixture components.

The invention is more advantageous in terms of the quality of the finished products / blends, using the principle of batch weighing and blending technology, but at a lower installation cost compared to plants of similar capacity and technology, and significantly less space requirements. The training, assembly, grouping, and expedient placement of agitator machines, assemblies, and equipment results in multiple material handling machines. the installation of a buffer tank, rack and a significant number of fixtures becomes unnecessary. Another notable advantage is that the simplification makes the operation, operation and maintenance of the equipment easier. It can also be operated by workers with less experience and less skills. To place the plant machinery, a building level waffle is needed. The number of component cells and ready-to-feed cells can still vary within wide limits, adapting to the needs, the number of ingredients to be mixed, and the nutrients to be produced.

The scale detects the amount of material when it enters the mixer or the feed screws of the mixer. The present invention also provides a high quality feed mix, using low-cost equipment, on the premises of smaller plants.
