Description

[Detailed description of the invention] impact separator And five beans 1 The present invention comprises a rotating centrifugal rotor surrounded by a collision ring and a concentric Impact type for grain, grain or flour-like substances with feed pipe and annular discharge channel Regarding separators.

Tutu mutual Various impact machines are used in the crushing or milling industry. depending on use This impact machine is also called an impact separator, sterilizer and enderator in English. It will be revealed. Technically, some of the processes are the same and some are very similar. for Depending on the application, the impact force or impact speed applied to the product can be adjusted and adapted.

Each piece of material has great strength. The whole grain is like that, and so is it. The same applies to coarsely ground flour and powdered flour. In contrast, for example, the brown weevil The hollowed kernels are brittle. Insects and insect eggs are very sensitive to impact. This fact is exploited by collisions. In this case, an impact machine called a sterilizer Thus, the empty grains are destroyed and the insects and insect eggs are killed.

Furthermore, an important purpose of the mill is to separate endosperm from the white flour core. Low When using an impact separator between the grinder and the sieve, the small particles generated during milling are are separated, and the endosperm particles that are stuck together are loosened.

For a large number of applications, the optimum circumferential speed of the centrifugal wheel, each specially selected The geometrical situation with allows a very good effect for the intended working result. Make it. Especially these days, maintaining these kinds of numbers or stopping basic foodstuffs from spoiling without using any disadvantageous thermal methods or functionally unknown radiation effects. It is recommended that this be done. This is a suitable mechanical action that allows for exclusive mechanical separation. Ru. Therefore, one of the main objectives of the present invention is to provide a mechanical solution in this sense. It is about improving.

The main drawback of the conventional known solutions is that they increase the product loading into impact machines. In some cases, the desired effect may be weakened as opposed to increasing the charge. This is at least , this may not be immediately recognized when killing small creatures that reduce their value. Related to troubling facts.

Similarly, it is not easy to determine whether the impact separation of endosperm and flour particles is optimal. . For this reason, impact-type machines are no longer used very often. In fact, this is a real test has been demonstrated in individual cases. However, in most cases individual percussion machines The amount charged exceeded the allowable amount for each.

L Bean Wataru Chef The problem of the present invention is that it is possible to achieve a true charge increase and improve the processing quality or almost 100% To neutralize the release of endosperm from insects or shells that reduce value while maintaining effectiveness. First, it was to improve impact-type machines.

A feature of the new invention is that the centrifugal wheel has at least two axially offset centrifugal passages. The reason is that it is equipped with the following.

With this invention, for the first time, less attention has been paid to the conditions of the product flow and impact location than previously It was acknowledged that it did not. If the product flow is strongly concentrated, some parts of the product flow may be affected by collisions. Forms a kungjong of the product on the protruding surface, which buffers the collision, e.g. hollow The impact forces necessary for crushing grain or insect eggs are no longer generated. In the second case , the product flow is subject to disturbing redirection effects. Too many products are in circulation within the scope of and in other ranges the product flow is too low. The impact separator is used when the mixture is processed. It is a difficult machine in terms of the laws of air flow in the sense of a ventilator; The physical law of product centrifugal force applies. Therefore, for obvious reasons, today In , the centrifugal seal flow is directly compared to a water model or an air model. because, Break apart materials by abruptly redirecting and accelerating them in a centrifugal wheel This is because a strong decomposition effect occurs. Use of more than one centrifugal passage in one machine Only then can the guidance of the product be controlled.

This doubles the product flow rate with less structural cost and the same effect of impingement. The actual test showed that this is possible. Surprisingly, new inventions especially Allows advantageous embodiments.

In particular, following the supply pipe, a guide device is provided in the centrifugal wheel, and this guide device is connected to the centrifugal wheel. It is very advantageous to couple it so that it rotates with the wheel. At that time, the guide device has multiple entrance passages. This inlet passage is a centrifugal passage in the form of an annular disc. You will be guided to the road.

When shifting the centrifugal channels axially, different shapes of inlet channels are necessarily created.

Again, in the case of two axially offset centrifugal passages, multiple inlet passages are required. It has been found from many tests that this is the case. In this case, the centrifugal passage away from the supply pipe is , twice the number of inlet passages should be provided. This is due to the centrifugal passage close to the supply pipe. This is twice the number of inlet passages. Alternatively, the corresponding area ratio for the inlet should be maintained. Thereby, accurate product bisection for both centrifugal passages is achieved. or both centrifugal passages produce identical centrifugal conditions for the substance.

Furthermore, an inlet passage opening into the centrifugal passage remote from the supply pipe has a reduced cross section on its outer periphery. It is advantageous to have a small built-in body. At that time, the built-in body is It is formed as part of a ring that is reduced in size.

Each identical inlet passage is arranged symmetrically. In another highly advantageous embodiment, A separate annular impingement surface is associated with each centrifugal passage.

The centrifugal wheel is configured as a double wheel, and the collision ring has two oppositely directed collisions. Providing a protruding surface results in optimal actuation for collisions. In this case, common material It is advantageous if the exit channel is attached to the double wheel or to the two impact surfaces. material The discharge channel opens tangentially to the product outlet.

In this advantageous embodiment, the collision surfaces are open in opposite directions with respect to the double wheel. It is formed as two truncated cones. Regarding self-cleaning and for impact action For convenience, the guide device is provided with flat guide vanes.

Furthermore, in a further development of the inventive concept, three or more centrifugal wheels are provided which are offset in the axial direction. is equipped with four centrifugal passages, and the further away from the centrifugal passages seen from the inlet, the more a number of inlet passages are open to this inlet or are provided with a corresponding area ratio. I'm here. A separate impingement ring is preferably assigned to each centrifugal channel.

If the motor is flanged directly to the casing of the impact separator, the The structural cost can be made very low. At that time, the centrifugal wheel is electrically The rotation speed is the same as that of the machine, for example, 3000 revolutions/minute.

The material discharge channel consists of two halves of approximately the same shape, this half being connected to the axis of the centrifugal wheel. is separable in a plane perpendicular to the axis of rotation.

The impact separator is configured in the form of a ventilator, and the product supply and product discharge are carried out vertically and horizontally. Any spatial direction can be selected, both in-plane and in the horizontal plane.

This allows almost complete freedom with regard to integration into the machining operation or facilitates a corresponding design of the device.

L Bean Dumplings I Ass Next, the present invention will be explained in detail based on examples.

− of Next, referring to Fig. 1, the upper part of Fig. 0 shows an axial cross section of the impact separator 1. There is. Electric motor 2 (lower half of the figure), which rotates approximately 3000 rpm, is connected to bolt 3 and the connecting flange. 4 to the lower fixed casing part 5 of the impact separator 1. ing. The connecting flange 4 is a seal for sealing the impact separator 1 from the outside. It is shaped to accommodate a. Upper casing part 6, lower casing part 6 The collision ring 7 is clamped and fixed between the lower casing part 5 and the collision ring 7. connected. Concentrically to both casing parts 5, 6, the supply pipe 8 is connected to the upper It is placed on the casing part 6. The material to be treated passes through this supply pipe into an impact fractionator. It is supplied to takeoff machine 1. A centrifugal wheel 9 is provided in the casing part 5.6. There is. This centrifugal wheel is connected to the electric motor 2 via a support bushing 10 and a safety bolt 12. It is attached to the shaft 11 of. The centrifugal wheel or centrifugal rotor 9 is a double wheel That is, it is formed as a double rotor 17. This double wheel has outer rotation disc 13, inner rotating disc 14 and this re-rotating disc 13.14 It is formed by a central separation ring 15 arranged between. At that time, supply An outer centrifugal passage 18 close to the tube 8 and an inner centrifugal passage 19 different from the supply tube 8 are formed. has been done. The collision ring 7 comprises two collision surfaces 20, 21 facing in opposite directions. There is. The impact surface forms two truncated cones opening in opposite directions. in this case , the outer impingement surface 20 is attached to the outer centrifugal passage 18 and the inner impingement surface 211 is It is attached to the centrifugal passageway 9 on the side.

A substance discharge passage 23 or 24 are provided.

This substance discharge passage expands like a ventilator towards the substance discharge passage 22 (Fig. 2). ing.

In FIGS. 3 and 4 only the guide device 30 is shown.

A plurality of short guide plates 31 and a plurality of long guide plates 32 are provided. Short information board is a product The air flow is guided into the inner centrifugal passage 18 (near the supply tube 8). The long information board is a product The air flow is guided into an outer centrifugal channel 19 (away from the supply tube 8). Figure 3: Smell The short guide plate 31 has a vertical hunting plate, and the long guide plate 32 has a horizontal hunting plate. The tag is attached.

As can be seen from FIG. 3, the guide device 30 is made integrally with a mold, for example, and 8.19 can be made from a steel plate and the picture parts connected to form a unit. Ru.

An assembly 33 in the form of a part of a ring is provided in the inlet region of the centrifugal channel 19. When the centrifugal passage 19 is completely closed (the shaded line of the ring is marked in Fig. 4), has a self-cleaning effect. In the case of a double rotor 17, the inner to outer inlet passage 35 A ratio of 2:4 for the number of side inlet passages 34 has proven effective. test We were able to prove that almost the same product flow as this shape occurs. This is the same as well as proof of the practical effectiveness of the new invention. The mixture of substance and air to be processed is It enters directly from the supply pipe 8 into the inlet passage 34 or 35 of the guide device 30 and is rotated. Ru. The mixture is accelerated in the inlet passage 34 or 35 and has a first impact at the pin 16. Perform tsu. By using two sets of ring-shaped bins 16, collisions can be achieved. The sudden action is doubled. Moreover, since a large number of pins 16 are provided, This has the advantage that the mixture is evenly distributed. In addition, the bottle has a certain degree of feather production. It's useful. The product air mixture is then separated by both centrifugal passages 18 or 19. The two flows that collide with each other due to centrifugal force on their own collision surfaces 20 and 21 change direction by 90°. The mixtures are immediately separated from each other. That is, the substance is mainly Each collides with a collision surface, and the air rubs against the collision surface.

Because the two material discharge passages 23 and 24 are arranged approximately symmetrically in an annular manner, collisions can be avoided. After that, a stable product flow and a stable air flow occur. water that spreads in the circumferential direction The bottle-shaped material discharge passage 22 allows the material to uniformly hit the collision surface 20 or 21. It also has the function of reuniting air and matter. This air and substances are After the exit channel 22, it can be further conveyed as a mixture by pneumatic conveying.

Various built-in layouts are illustrated in FIGS. 5-8. As a result, the opposition The operation of the shot separator 1 is always guaranteed independent of the installation position 1.

In Figure 5, the material to be processed is fed into the impact separator 1 from vertically below, and carried flat. In FIG. 6, the product is fed vertically from above. In contrast to this In Figures 7 and 8, untreated material is fed horizontally to impact separator 1. Ru. In Figure 7, the product moves vertically downwards, and in Figure 8 it moves vertically upwards. Moving.

FIG. 9 shows another embodiment with triple centrifugal rotors 9. In this case, each distance Each cardiac passageway 51 or 52 or 53 has one specific impingement surface 54 or 55. or 56. The product flow is guided downward from both collision surfaces 55 and 56, It is guided upward from the collision surface 54. Here again, the guide device 30 is as shown in FIGS. 1 to 4. to ensure uniform product distribution with respect to all aisles.

In FIG. 10, the centrifugal rotor is configured as a double rotor similar to FIGS. 1-4. However, it has two collision surfaces 61 and 62. This collision surface directs the product flow in the same direction. guide you downwards.

FIG. 11 shows the centrifugal rotor of FIG. 10 doubled. But the product is against You will be guided in two directions. The centrifugal rotor 70 is formed as a quadruple rotor. Ru.
