Description

Devices for packing bulk materials are already known, which enclose the receivers arranged in a circle in a vertical plane (Suspended to a separate weight beam for each of them, carrying a device for guiding the material from the pitched surface to the receiver, which ensures a gradual reduction of the material supply As far as the rocker arm is deflected from the initial position, the adaptations of such devices, which provide a gradual reduction of the material feed, are rather complicated in design.

The proposed device of the same type simplifies the design of these devices and has the peculiarity that the device for directing material into the receiver is carried out in the reference of a reflective visor located at the initial position of the rocker arm against the material flow running down from the ramp and approximately the shape of a triangle facing top up and down stream when the rocker arm is fully deflected from the initial position.

In FIG. 1 depicts

longitudinal section of an exemplary form of the device; FIG. 2 is a front view of the visor and receiver of the software device of FIG. one; FIG. 3-6 illustrate the effect of the visor of the device at its various positions relative to the pitched surface.

From the hopper 1, the material is uniformly delivered to the surface 2. The material can be distributed over the pitched surface 2 in various ways that are not substantially reflected on the entire system, for example, by a fast-rotating disk 3, from which the material is dropped to the surface 2 by the action of centrifugal force. the best distribution of material over the surface 2 above the disk 3 is supported by a fixed screen 4, reflecting the material in the desired direction.

On the surface 2, the material escapes and falls into the casing 5, then it is collected in box 6.

 the edges of the surface 2 are located reflective visors 7 (Fig. 1), mounted on the rocker arms 8, which are star-shaped around the axis 9. The rocker arms 8 can swing on the supports 10 rigidly fastened with the AELCO 9. On the rocker arms 8 are suspended receivers 11 and 12 s put on them cascade loads 13, lowering, imis into cups 14. Sequence is installed on the disk 15 fastened to the axis 9. Each rocker arm 8 is equipped with a counterweight 16.

The operation of the device proceeds as follows.

The bulk material flowing out of the hopper 1 is scattered over the pitched surface 2, run down over it, reflected from the visor 7 and fed to the receiver 11. As it is filled, the receiver 11 together with the visor 7 is lowered and the material supply to the receiver decreases due to the fact that it is upstream The narrower part of the goat 7, which is approximately the shape of a triangle, with its tip upward, is established. This ensures dosage accuracy. When the weight reaches the predetermined value, the upper edge of the visor 7 will fall below the edge of the surface 2 and the filling of the receiver will stop. Thus, the visor 7 is a kind of automatic controller that gradually reduces the flow of material entering the receiver as it approaches the given weight and stops it when it reaches that weight. A prerequisite for automatic material feed control is the establishment of a hard link between the weight of the material in the receiver and the position of the visor 7 relative to the surface 2. This is achieved by using "cascade weights 13, the effect of which is illustrated in FIG. 3-6. The flow of material entering the receiver loads it and when it reaches a weight that balances the counterweight 16, receiver I lowers until the washer 17 is strengthened, and t 12 starts to lift the lower cascade load 13 (Fig. 4), which gives the first equilibrium position. With further loading of the receiver, the ha ha 12 still rises and stops, reaching the second cascade load (Fig. 5). FIG. 4 shows the third equilibrium position when a narrow part of the visor 7 is located against the edge of the surface 2. When the specified weight is reached, the lower cascade weights touch the upper, called “control,” and the beam 8 stops, and the visor 7 descends below the edge of surface 2 (Fig. 5 ) and bulk material backfilling ceases. In case of accidental overloads, the control weight is raised and the receiver 11 is lowered significantly below the position corresponding to the normal weight (Fig. 6). The combination of the adjusting visor 7 and cascade loads is the central unit of the entire system, ensuring its operation. To calm oscillations, the rocker arms can be equipped with dampers.

The entire rocker system and the pitched surface 2 rotate around OSI 9, and each receiver passes about 1/4 of the circumference in the process of weighing, starting from the zone of intensive backfilling caused by using fixed stationary 4, and ending with the zone of backfill, in which the final dosage occurs. Having loaded to a given weight and dropping below the edge of the surface 2, the receiver 11 continues to move, the finger 18 hooks on the fixed stop 19 (Fig. 2), the receiver overturns and its contents are poured into the funnel intended for it, after which the receiver 11 under the influence of the load 20 returns to the starting position. If for some reason the linkage does not correspond to the specified value, then the receiver 11 passes at a different level, the finger 18 engages not with the stop 19, but behind another stop positioned along the receiver and not shown in FIG. 2, and then the receiver with a non-handling weight is emptied directly into the casing 5. After the receiver is emptied, the rocker with the visor rises under the edge of the surface 2 and the weighing process is repeated.

Using the principle of a self-adjusting rocker is possible not only with the star-shaped arrangement described above and vraeni around the common axis, but also in other combinations, for example, these can be single rocker arms, fixed in space.

The above described device can be used for the automatic weighing of gunpowder, powder for hard alloys, tea, etc. In some cases, additional devices may be required, such as a fan for removing dust, a pre-cleaner for bulk material, etc.

Subject invention

The devices for packing® bulk materials, which enclose receivers, suspended from a separate beam for each of them, lay down; they have on themselves a device for guiding material from the pitched surface to the receiver, which ensures a gradual decrease in the supply of material to this receiver as deflection of the rocker arm from the initial position, characterized in that the device for guiding the material into the receiver is made in the form of a reflective visor 7 located at the initial position of the rocker arm against ayuschego with a sloping surface 2 of material flow and having approximately the shape of a triangle, the apex of inverted up and below opuskayuschegos stream at full deflection of the rocker from the initial position.
