SU716832A1 - Unit for preparing concrete mix and dispensing it to moulding stations - Google Patents

Description

The invention relates to the field of construction, namely, to installations for the preparation and distribution of concrete mixture at molding posts, mainly at iron factories, tons of products.

A known installation for preparing a concrete mix and distributing it at the molding posts, containing warehouses of aggregates and cement, consumable bins and aggregates and cement metering devices in the concrete mixing shop, dry mix blender for concrete mixers, dry mix feeder, jet mixer, storage bin for concrete mix, feed conveyor concrete mix, concrete spreader 111.

The closest of the known devices is a plant for preparing and dispensing concrete mixture at the molding stations, including warehouses of aggregates and cement, myografratsionnymi dispensers and mixers with a water supply system 2J.

The disadvantages of the known installations are their considerable metal consumption, as well as the impossibility of preparing the mixture of the required quality, the considerable consumption of cement and the significant duration of the technological process of preparing the mixture.

The purpose of the present invention is to eliminate these drawbacks, namely, reducing metal consumption, improving the quality of the mixture being prepared, reducing cement consumption and speeding up the process.

This goal is achieved by the fact that the installation for the preparation and distribution of concrete mixture in a mold. Multiplexing dispensers and mixers with a water supply system are equipped with a pneumatic conveying system for supplying dry components of the mixture, made in the form of a tube pump connected to the mixer with a mixer, the upper part of which is made in the form of a tangential cyclone with nozzles for ps stream water into the mixer

5, in the pipeline in front of the mixer, a device was installed for a pair of steam, and the warehouses of the aggregates were made in the form of batteries of a silo jar grouped into blocks by fractions.

The invention is illustrated in the drawings, where; Fig 1 shows an installation unit; Fig 2 - cx (gma installation in axons errin.

The installation for the preparation and distribution of the concrete mix by molding posts includes a battery si, glossy cans, grouped blocks, each of which has banks of aggregates 1 and 2 feeders 3 and 4, a multi-fractional dispenser 5 with a shutter 5m b and a drive 7 , tekeometric sensors 8, automatic control system 9 with software devices, see f chamber pump 10, compressed air supply system 11, switch 12, transport pipelines 13, device; steam supply 14, controller 1.5 with temperature sensor 16 automatic a cusher 17 and a switch-on sensor for pa-ea 18c time relays connected to a compressed air supply circuit 11, a mixer 19 installed at the end of the transport pipeline with a tangential cyclone 20 in its upper part, a scrubber 21 f a system fan 22 of water system 23, associated with the fogs 24 J regulator diaphragm 8.1 h 25 water dispenser and additional 26.

The installation works a trace of the ego-cm image,

An automatic control system with software devices 8M 9 receives an order for a specific portion of the mixture of a certain composition. After that, alternately, the feeders 3 n 4 silage jars of aggregates 1 and cement 2 are supplied to the components in the multifraction metering device 5 installed on tenes 4 "4 sensors 1, where dosing of the components of p followed by failure. The gate of the chamber pump 10 is transferred to the chamber pump. Then, using a pneumatic conveying system, the material is fed into the mixer 19, installed directly above the place. For 8-20 meters from the transport pipeline vkod 13 to the system

through the device 14, steam is supplied by opening the automatic valve 17, controlled by the steam switch 18 sensor cw, @ sak {: I through a time relay with a compressed air signal system. WHO. the VC from the mixer 19 is sucked off the torso valve. 1 22. Adjusting the amount of diaphragms supplied to the injectors during the operation of the diaphragms 25. To ensure the replacement of chamber pumps and systems of transport pipelines on the latter; set switches 12,

The proposed economic effect from the use of this installation at the concrete goods plant with the gross output of 140-200 thousand, M per year will be 550-600 thousand „rubles.
