Description

They are pressed into the bunker, they include the drive of the feeder, which rotates the impeller and the screw agitator. The latter, rolling over the bunker, loosens and mixes the materials, which improves their flowability. The intensity of the outflow also increases due to the increase in the number of impacts on the material due to the use of a two-way agitator. 3 il.

The invention relates to devices for the storage and distribution of difficult-to-flow materials and can be used in folk farms, mainly in agriculture, as well as in the chemical and food industries.

A device for accumulating and dispensing hard-flowing materials is known, which comprises a hopper with a conical lower part. A dispenser is connected to the outlet of the bunker, the working member of which is connected to a paddle shaker placed at the bottom of the bunker by means of a hinge. When the metering unit is put into operation, its working body rotates and through a hinge the rotation of the agitator, which uses its blades, loosens the nearby material and facilitates its movement along the hopper to the working body of the dispenser. In the event of the formation of a vault, the upper end of the agitator by a tangential force arising from the forces of friction rolls over the bunker until it touches the resulting vault and the blades disrupts its balance. When the vault collapses, the agitator rotates around its axis, not moving along the bunker, since the impact of the material on it from all sides is the same and the material resistance balances the tangential force that rolls the agitator around the perimeter of the bunker. Since the agitator cannot roll around the perimeter of the bunker in the absence of a vault in the area of its location, in the zone of the absence of the agitator the material is caking and does not pour out of the hopper.

A disadvantage of the known device is the low rate of agitating difficult-flowing materials.

The closest in technical essence is a device for the accumulation and distribution of difficult-to-flow materials containing a hopper, to the bottom flange of which a feeder body is attached. In the case there is an unloading window, covered with a flap, and on the shaft of the drive mechanism

mounted working body, made in the form of a blade impeller. The number of blades is greater than one. A single-thread screw agitator is connected to the working member by means of a cardan joint, at the upper end of which there is a roller fixed to the bunker. In addition, at the upper end of the agitator, a mechanism is installed to control the force of adhesion of the roller to the bunker. Materials are mixed in the bunker for mixing and feeding for other operations. The unloading window in the case of a feeder is blocked by a flap. Then include a drive mechanism that rotates

working body of a feeder and single-thread screw agitator. Due to the adhesion of the roller to the hopper, a forced rolling of the agitator around the bunker perimeter is achieved. Since the turns of the auger

are made so that the material is captured and moved upward, then during operation of the device, the materials are continuously circulated in the bunker, as a result of which they are mixed. After that, the unloading window in the feeder housing is opened and the mixture of components is fed to other technological operations, and the screw screw is turned and mixed.

In the device, the agitator auger is made one-way., Therefore, the intensity of the impact on the material is low. The screwing of the auger is continuous, with caking of the material or when loading into the hopper.

compacted (lumpy) material does not provide effective rapid loosening (destruction) of the pieces. As a result, mixing is difficult, and the presence of packed pieces of material worsens

flow and uniformity of materials. In addition, the impeller impeller is made with a number of blades, a large number of auger inserts, so that when the device is operated, the material of the auger coil is not captured and removed from all impeller blades, therefore during mixing or when dispensing the mixture in small doses

material is compacted in the housing by impeller blades of the impeller, thereby clogging the discharge window and increasing supply irregularity.

A disadvantage of the known device is the low intensity of agitating and mixing of hard-flowing (compacted) materials.

The purpose of the invention is to increase the intensity of the process of outflow of difficult-flowing materials.

The goal is achieved by the fact that in a device containing a conical bunker, a feeder with a working body in the form of a blade impeller and a screw agitator placed in the bunker connected to it by means of a cardan joint, is a multiple screw agitator, at the extreme the measure is two-way, and the teeth are cut along the periphery of one of the windings, and the number of blades of the impeller is equal to the number of screw turns of the screw.

By making the screw multiple and teeth along the periphery of one of the windings, loosening of adjacent (lumpy) materials is facilitated and the process of their outflow and mixing is intensified, since the number of impacts on the material with each turn of the screw increases in proportion to the number of entries. Scalloped winding easily cuts into pieces of compacted material and forms alternating grooves and protrusions on their surface, the latter are easily cut off (destroyed) by continuous winding.

Making the impeller with the number of blades equal to the number of screw augers prevents the impeller from compacting the material and reduces the energy consumption of the process, since the screws of the auger allow material to be drained from each impeller blade.

Figure 1 schematically shows the device; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 1.

The device consists of a conical hopper 1 (figure 1) to the lower flange of which the case 2 of the feeder is attached. In the housing there are windows 3, blocked by flaps 4. On the shaft of the drive mechanism 5 an impeller is installed, which consists of sleeve 6 and blades 7. Through a hinge 8, a multiple starting, at least two-way agitator consisting of shaft 9 is attached to the impeller sleeve gear 10 and continuous 11 windings. The coils are aimed so that they, capturing the material, only direct it upwards. The number of impeller blades is equal to the number of auger passes. For example, with a twin-auger screw, the impeller has two blades. A roller 12 is supported at the upper end of the auger shaft, resting on the hopper. In addition, a force control mechanism 13 is mounted here.

clutch roller with hopper.

Under the unloading windows 3, conveyors 14 are installed, feeding material for other operations.

The device works as follows.

Materials intended for storage, mixing, and

issuing. In this case, the windows 3 are closed by flaps 4. The drive mechanism 5 is turned on, which rotates the impeller and the screw agitator. Since the agitator is made in the form of a screw, the turns of which are directed

so that the material is captured and directed upwards, as well as the possibility of forcibly rolling it around the perimeter of the hopper, while agitating

materials. By making the screw multiple (two-way) and cutting the teeth on one of the windings, the agitating and mixing process is intensified, and loosening is also facilitated.

compacted (lumpy) materials, because with each turn of the screw the number of impacts on materials increased by the number of visits (twice). In addition, barbed winding is lighter than solid, cuts into pieces of compacted material and cuts grooves and protrusions on their surface, the latter are easily destroyed (cut off) by solid winding. Since the number of blades of the impeller and the number of visits

the augers are equal, and the angles of inclination of the blades and windings to the axis of rotation of the same direction and position of the beginning (Hi) of the turns of the screw below the level of the blades (H), the material in the feeder housing is prevented from being compacted, since the coils remove the material from each blade of the impeller.

After mixing, the shuttered 4 windows 3 and the material are opened

blades mi 7 impeller is carried through

windows on the conveyors 14, which serve

him on other operations.

The application of the present invention allows to improve the process of expiration, as well as to combine the operations of mixing, opening and feeding of hardly flowing materials.

By loosening and mixing the compacted materials, their flowability is improved and a more intensive outflow is achieved. In addition, the preparation of a mixture of materials by means of such a device makes it possible to reduce the number of metering mechanisms necessary to effect the supply of each component separately. Thus, in the production of mixed feeds, you can prepare a mixture of various additives (salt, chalk, urea, etc.) and introduce it into the composition of the feed. This makes it possible to replace with one device several feeders necessary for separately inputting each component. In this case, the three feeders MVU-0.5A (for salt, chalk, urea) are replaced with one device.
