Description

FILLER FEEDING LINE FOR PREPARING MIXTURE

The utility model relates to the field of manufacturing concrete and reinforced concrete products.

A known installation for the manufacture of a dry mixture, including a filler supply line containing a filler warehouse, a drying compartment, an elevator loading conveyor, an elevator, feeding filler into a feed hopper, which is connected via a screw conveyor to a mixer.

(SU No. 2033327 C1, B28C9 / 00, 1993)

A disadvantage of the known technical solution intended for the manufacture of a dry mixture is its rather low productivity of the filler feed line, due to the complexity of controlling the filler supply process from its storage warehouse to the mixer, associated with the use of various types of conveyors and the performance limitations of dispensers and hopper leaks. In addition, the use of open types of movement of the filler adversely affects the ecological environment of production. An important factor in this is the use of closed types of movement and storage of filler with a minimum length of movement of filler along the processing chain, which greatly increases the ability to provide the required performance and feeding modes, reduces the wear of process equipment and improves the ecology of production.

B28C9 / 00

feed rates while reducing wear on process equipment.

The technical result of the utility model is to improve the ecology of the production of filler feed from the warehouse to the mixer, increase the feed rate and reduce equipment wear.

The essence of the utility model lies in the fact that the filler feed line for preparing the concrete mixture includes a warehouse, a drying compartment, an elevator loading conveyor, an elevator, a feed bin; and filler in a feed hopper, which is connected through a dispenser with a screw conveyor and a mixer, and the elevator loading conveyor is made with a screw , the elevator is equipped with a vibrating screen, and the feed hopper is made in the form of a horizontal hollow cylinder equipped with at least two truncated cones in the lower part to drain the filler into wines commodity conveyor.

Figure 1 shows the filler supply line for the preparation of concrete mixture, including;

1. filler warehouse;

2. drying department;

3. elevator loading conveyor;

4. vibrating screen;

5. elevator;

6. consumable hopper;

7. The cone of the filler drain;

8. screw conveyor;

9.doser;

10. mixer.

The filler (sand) from the warehouse I is mixed, shipped to the drying compartment 2, from where, after reaching the required parameters, the loading conveyor 3 is fed into the elevator receiving device 5,

equipped with a vibrating screen 4. The use of a screw conveyor increases the ecology of production, and the use of a vibrating screen, with which large and medium fractions are extracted from the filler, reduces the friction wear of subsequent processing equipment. The elevator 5 feeds the filler into the feed hopper 6, which is made in the form of a horizontal hollow cylinder (such as a tank), which is equipped with three truncated cones 7 in the lower part to drain the filler into the screw conveyor 8. Using the cylindrical shape of the feed hopper 6 according to the utility model with several conical filler drains into the screw conveyor 8 can increase the overall speed of the filler in the feed line. After that, the filler screw conveyor 8 through the dispenser 9 serves in the mixer 10.

The operating experience of the filler feed line for the preparation of concrete mix showed an improvement in the ecology of production, an increase in the feed rate and a decrease in equipment wear.

Claims (1)
