Description

The invention relates to concrete plants with an annular location of bins and a carousel metering device.

A distinctive feature of this invention is the use of a carousel metering device in combination with an annular arrangement of bins for materials, which leads to a decrease in the cost of a concrete plant compared to concrete plants mounted in a vertical pattern.

FIG. 1 shows a schematic plan of a concrete plant; in fig. 2 is a vertical section of it; in fig. 3 - details of the carousel metering device; in fig. 4 is a diagram of the organization of the cement supply.

The concrete plant includes a carousel mill consisting of a one-piece metal pipe / with a diameter of 200 mm, which, with its upper and lower ends, rests on conical baffles 2; the support of the upper bolster is bar 3. To the pipe / with the help of round metal gussets 4, as well as struts 5 from metal corners, a system of cantilever beams 6 of channel bars is attached. Six metering hoppers 7 are suspended to these beams on bolts.

The metering hoppers are made of sheet steel and equipped with easy-folding heads. Each metering hopper is divided by a vertical partition 8 into two compartments: one is smaller for sand, the other is larger for gravity. The cubic capacity of each compartment corresponds to the required volume of gravel or sand for one batch, and in general, the capacity of the hopper is equal to the capacity of one batch, i.e. the capacity of the concrete mixer bucket. If it is necessary to change the productivity of a concrete plant, the dosing bins can be easily replaced with any other tank, depending on the need.

After suspension of the dosing units on the upper shelf of the channels, wooden decking-floor is arranged on 9 of 40–50 mm boards.

The carousel freely rotates around the vertical axis of the pipe from a slight force and is located below the ground level so that the top of the dispensers is 30 --- 40 cm below the ground level. Above the carousel, overlap the JO with a lantern: //. . . .

Cement hoppers 12, fine gravel 13, gravel 14 and sand 15 located around the carousel mill are up to 4 m high and can have a significant capacity exceeding the capacity of the bunkers of conventional concrete plants, and at the same time they can be heated by simple means inert materials (for example, using steam needles), which is very important when working with znmpee time. The trays of the gravel and sand bunkers are so spread out across the top of the carousel, that when stacking the dosing bins over the skins of the concrete mixers 17, the remaining dosing bins turn out to be iodine bunkers for gravel and sand.

Gravel and sand silo trays are equipped with segment closures. Each metering hopper, making a circular dvnzhenie. it is filled with gravel and packed in the required dosing volume. This is a continuous filling of the bopker-doz.atorov when moving on the carousel but the way to the concrete mixers and the nighttime immediately load them into the erect buckets of the concrete benders during the period of mixing; -5 previous pages in the drum of the concrete mixer.

Thus, in total, with two workers on the carousel, uninterrupted loading of the cement and concrete 17 of any capacity is achieved, with the continuity of the cyclops of concrete, i.e. with the use of the machine.

 Cement carousel is manufactured by workers; from a warehouse 18 adjacent to it, in mobile kiteyperap-wagia 19 with passing them through the weights 20. Coypera-trolleys roll up on the truck in the intervals between the bunker chamber and pass them through the warehouse 18. Similarly, after the empty slots, they pass through the intervals 18 to the bunker chamber-dispensers in their passage past the warehouse 18. Similarly, after empty slopes, they pass through the intervals between the bunker chamber-dispensers and pass them past the warehouse 18. Similarly, after empty slots, they pass through the intervals between the bunker chamber-dispensers and pass them past the warehouse 18. Similarly, after empty slots, they pass through the intervals between the bunker chamber-dispensers and pass them past the warehouse 18. Similarly, after empty slots, they pass through the intervals between the bunker chamber-dispensers and pass them past the warehouse 18. Similarly, after the empty slopes, the bunker chamber-dispensers will pass through the warehouse 18. Similarly, after the empty slots, they pass through the intervals between the bunker chamber-dispensers and pass them past the warehouse 18. onn are removed back to the warehouse for loading. The loading of the bunkers with gravel is carried out with a belt conveyor, and the supply of sand with a four-meter lifting platform or trapsport (not shown on the drawings).

If it is necessary to enrich the gravel in a concrete plant, a gravel wash 22 is entered between the gravel storage tank and conveyor 21, from which the gravel flows through the wooden troughs into the gravel bupkers. A gravel washer with a conveyor belt is installed in a workshop 22 for gravel.

Supply of inert materials and cement to the plant and finished concrete from the plant can be produced; 1, by any means of transport.

The subject is invented and

A concrete plant with arrangement of mechanisms and devices according to a horizontal scheme, characterized in that the material bins and the concrete mixers are arranged on the ring, and a device in the form of a carousel with metering bunkers suspended from it is used to meter materials and supply them to the buckets of the concrete and benches.
