The invention relates to a reflector detacher for materials in the form of zerkrup or flour with a rotating centrifugal wheel surrounded by a reflection ring and having a concentric feed pipe, an annular

general channel.

The purpose of the invention is the improvement of the reflective machine to provide

an increase in producer-nose gi, while preserving, however, quality

You, respectively, are almost 100% effective, be it the neutralization of insects that reduce the quality or the release of the endosperm from the membrane.

The invention is characterized in that the centrifugal wheel has at least two axially displaced central channels.

Only with the help of the invention it was found that so far too little attention has been paid to the product flow, or product flows, on the one hand, and the situation in the field of reflection, on the other hand. The consequence of too much concentration of the product stream is that a portion of the product stream is created on the reflective surfaces as if a cushion from the product, so that reflection is damped and, for example, the impact force required to break the hollow grains or insect eggs no longer occurs. In the second case, the product flow undergoes an interfering deviation, and too much product flows in certain areas, and very few in others. A reflective detacher is a complex machine insofar as the processing of the mixture takes place. Both the laws of airflow in the sense of a fan and the physical laws of a food centrifuge apply. For obvious reasons, to this day it has not been possible to directly compare the dense flow centrifuge with a water or air model, since extreme delamination occurs in the centrifugal wheel due to the strong deflection and acceleration of the material. Only through the use of more than one centrifugal channel

Noah machine can master the direction of the product.

Experiments have shown that in this way, with insignificant structural additional costs and the same reflection efficiency, the passage of the product can be doubled. Surprisingly, the new invention allows a large number of particularly preferred options.

So, it is especially preferred if c. a centrifugal wheel is provided with a guide apparatus and / to the feed pipe fixedly connected to the centrifugal wheel during joint rotation. In this case, the guiding apparatus has a large number of supply channels directed to the centrifugal channels in the form of an annular disk.

With the axial displacement of centrifugal channels, various forms of supply channels are forced to arise. Here, a series of experiments showed that in the case of two axially displaced centrifugal channels, a large number of supply channels are required, and the centrifugal channel remote from the supply pipe must be given twice the number of supply channels compared to the number of supply channels for a centrifugal channel located near the supply pipes. Accordingly, an appropriate ratio of supply surfaces must be maintained. This resulted in an exact bisection of the product for both centrifugal channels, respectively, both centrifugal channels creating identical centrifugation conditions for the material.

It is further preferred that the feed channels included in the centrifugal channel remote from the feed pipe have a tapering cross section on the outer circumference. In this case, the insert is made in the form of an annular section with a narrowed shape in the direction of the axis of rotation.

Correspondingly, the same supply channels are arranged symmetrically. In the following, completely particularly preferred embodiment, each centrifugal channel is provided with a special ring-shaped reflective surface.

Optimum performance with respect to reflection occurs when the centrifugal wheel is made in the form of a double wheel and the reflective ring has two reflective surfaces directed oppositely to each other, with

this predominantly double wheel, respectively two reflective surfaces, is provided with a joint material withdrawal channel included in the tangent

material withdrawal channel.

In this preferred embodiment, the reflective surfaces are formed with respect to the double wheel in the form of two truncated cones opening in the opposite direction. With respect to both self-cleaning and reflective effect, the guide vanes have flat guide vanes.

5 Further, with the further development of the idea of the invention, it is possible to realize a centrifugal wheel with three or four axially displaced centrifugal channels, and, if viewed from the supply side, the more distant the centrifugal channel is, the greater the number of supply channels must enter this channel, respectively, must match the corresponding supply surface. In this case, predominantly each centrifugal channel is given one separate reflective ring.

Design costs can be kept very low by directly flanging the drive motor to the housing of the reflective detacher. The centrifugal wheel then has the same amount

5 revolutions per minute, like an electric motor, for example, 3000 rpm.

The material withdrawal channel may be formed from two approximately equally shaped halves, which are

0 separable in a perpendicular plane with respect to the axis of rotation of the shaft of the centrifugal wheel.

In a very preferred manner, the reflective detacher is in the form of a fan, so that the product inlet and product outlet can be selected in all directions in space, both vertically and horizontally.

This allows for almost complete freedom in

With regard to integration into the processing process, it accordingly facilitates the corresponding design of the installation.

In FIG. 1 shows a reflective detacher, an axial sectional view; on the

5 of FIG. 2 is a sectional view of FIG. 1; in FIG. 3 - double wheel guide apparatus; FIG. 4 is a plan view of FIG. 3; in FIG. 5-8 illustrate various options for incorporating a reflective detacher: FIG. 9 is the following embodiment with 3x

by centrifugal rotor: in FIG. 10 is a further embodiment in which the i centrifugal rotor is made in the form of a double rotor; in FIG. 11 is a doubling of FIG. 10 with product deviation.

At the top of FIG. 1 shows a reflective detacher 1 in the form of a section in the axial i direction. Approximately 3,000-rev (motor 2 / lower half of the ignition / with screws 3 and a connecting flange 4 is fixedly attached to the lower fixed part of the housing 5 of the defective detacher 1. The connecting flange 4 is designed in such a way that the seal / seal for sealing the reflective} etasher 1 is placed outside. The upper part of the housing 6 is connected to the lower part of the housing 5 in such a way that the reflective ring is clamped between them t. Concentrated with respect to both parts (housing 5 and 6 on the upper part of the housing ( a b install on the supply pipe 8, through the second material to be processed, it is introduced into the reflective detacher 1. In parts of the case 5 and 6, a centrifugal t-wheel is located 9. In this case, this wheel is mounted on the shaft 11 of the motor 11 through the bearing sleeve 10 and the safety screw 1 2. or the centrifugal rotor 9 is made of an external rotating disk 13, an internal i rotating disk 14, and also located between the two rotating disks 13. 14 of the spacer ring 15 assembled by means of the 16 axles into a double t wood , respectively, two rotor 17. In this case, an external centrifugal channel 18, close to the supply pipe 8, appears, and also an internal centrifugal channel 19 remote from the supply pipe 8, the Reflective ring 7 has two opposite I-directional reflective surfaces 20, 21, which which are two truncated cones that open in opposite directions, with the first reflective surface 20 attached to the outer centrifugal channel 18 and the inner reflective surface. 1 attached to the inner centrifugal (anal 19.

In the direction and periphery with respect to the centrifugal wheel 9, or the double wheel 17, there is a discharge channel of the paterial 23 or 24, expanding in the first fan in the direction of the channel of the material return 22 (Fig. 2). In FIG. 3 and 4, a guide i apparatus 30 is shown. The guide apparatus 30 has- (two types of flat guide plates - (pins: short guide plates 31,

directing the air flow with the product into the inner (close to the supply pipe 8) centrifugal channel 18, as well as long guide plates 32, directing the 5 air flow with the product into the outer (remote from the supply pipe 8) centrifugal channel 19. Short guide plate 31 in FIG. 3 has a vertical hatch and a long guide plate 32 has a horizontal hatch.

As can be seen from FIG. 3, the guiding apparatus 30 can be made integrally, for example, in the form of a casting, centrifugal ducts 18 and 19 can be pulled out of the steel sheet 5 and both parts can be assembled into a single unit.

The centrifugal passage 19 is also completely self-cleaning when an insert 33 is placed in or in them

0 of the annular portion in the feed zone of the centrifugal channel 19 (shaded with circular rings in Fig. 4). In the double rotor 17, a 2: 4 ratio of the number of internal supply channels 34 has been established

5 and external supply channels 35. The experiments proved that in this embodiment almost identical product flows are established, which also constitutes a confirmation of the positive effect

0 new invention. The processed mixture of air with the material enters through the supply pipe 8 directly into the supply channels 34 or 35 of the guide apparatus 30 and is rotated.

5 In the supply channels 34.35, the mixture accelerates and undergoes a first reflection on axis 16. By using two sets of axes 16 arranged in a ring-like fashion, this reflection effect is even doubled.

0 However, a large number of axes also provides the advantage of uniform distribution of the mixture in the circumferential direction. In addition, they give a certain effect of the scapula. Air mixture with product

5 is then separately ejected by both centrifugal channels 18, 19 onto its own reflective surfaces 20, 21. It can be easily seen that due to the 90 ° rotation for both flows, the opposite

In direction 0, the mixture immediately separates, the heavy material is reflected onto the intended reflective surface, and air passes further. Due to the annular and generally symmetrical arrangement of both of the material outlets 23 and 24, a stable air flow is generated in addition to a stable product flow, also after reflection. The channel for the removal of material 22 in the form of a water turbine, expanding towards

peripherals / supports uniform loading of the reflective surface 20, 21, and supports the re-combination of air and material, which in the form of a mixture after the material withdrawal channel 22 can be transported further by pneumatic conveying.

Figs. 5-8 depict various built-in positions. This expresses the fact that regardless of the position of the built-in, the working effect of the reflective detector 1 is always ensured.

In FIG. 5, the material to be processed is fed into the reflective detacher 1 vertically from below and discharged in the horizontal direction; in FIG. 6, the product is fed vertically from above. Compared to this, the starting material in FIG. 7 and 8 enters the reflective detacher1 1 horizontally. Product Transfer in FIG. 7 occurs vertically downward, and in FIG. 8 - vertically up.

In FIG. 9 shows the following embodiment with a 3-fold centrifugal rotor 9, each centrifugal passage 51, with 52, 53, having one own reflective surface 54, 55, 56. From both reflective surfaces 55 and 56, the product flow deviates downward, and from the reflective surface 54 - up. It is also important here that the guide apparatus 30 is made according to the same rules as in FIG. 1-4, and uniform distribution of product was ensured for all channels.

In FIG. 10, the centrifugal rotor is made in the form of a double rotor similarly to FIG. 1-4, however, with two reflective surfaces 61, 62 deflecting the product flow in the same direction below.

big. 11 is a doubling of FIG. 10, but with a deviation of the product in two opposite directions, the centrifugal rotor 70 being a 4-fold rotor.
