Description

The utility model relates to the field of construction, namely, equipment for the preparation of concrete and mortars.

A well-known concrete production plant, the technological equipment of which includes a receiving hopper for sand and gravel, a conveyor belt, a swivel funnel for loading sand and gravel consumables, water tanks, sand, gravel, cement, water, concrete mixers, a ready-mix bin (Polytechnic Dictionary, M., 1980, p. 54).

Concrete production at such plants requires the use of large areas, the construction of special cement silos of high height. The known design is difficult to assemble and disassemble, requires extensive preparatory work, is cumbersome, which makes it difficult to place the plant next to the construction site.

Known concrete mixing plant containing a warehouse of concrete components with sector storage bins, a dosing device with a bucket, a mixer, a hopper of the finished mixture, a device for feeding components to the mixer, as well as movable, regulating the flow of components of the damper installed at the openings of the discharge windows of the storage bins equipped with a return device with a control stop interacting with the bucket during operation (RF patent No. 2054999, IPC B 28 C 9/00 1996 publication).

The task of creating a real utility model is to expand the arsenal of technical means used for the production of concrete and mortars of various compositions, and to create a compact plant design that can be quickly mounted next to the construction site and is convenient in controlling the production process.

The essence of the proposed utility model is as follows.

The plant for the production of concrete and mortar contains technological equipment, including sand, crushed stone and cement consumables, consumables for water and chemical additives, weighing batchers, conveyors, a mixing machine, screw feeders, a compressor and a control panel. All elements of technological equipment are placed in a modular scheme in separate quick-detachable and quickly installed box-type blocks, placed on a common foundation base and mounted at least on two levels.

Technological equipment is placed in blocks that form an assembled U-shaped configuration in the horizontal plane.

When the blocks with equipment are located at three levels in the lower level, the equipment is placed in three blocks, one of which contains a control panel, a mixing apparatus and dispensers of cement, water and chemical additives, the adjoining second block contains consumables for chemical additives, a compressor and a conveyor a dispenser for loading the mixing apparatus with sand and gravel, and in the third block, located opposite the second, a boiler installation is placed.

The equipment at an average level is placed in three blocks, one of which is installed above the block in which the consumables are located

containers for chemical additives, a compressor and a metering conveyor for loading the mixing apparatus with sand and gravel, contains sand and gravel consumables, and the other two blocks form cement containers, one of which is installed above the block containing the control panel, mixing apparatus and dispensers cement, water and chemical additives, and the second, containing an additional supply tank with water, is installed above the block with the boiler room.

Two blocks are placed in the upper level, which form cement containers and are installed respectively above the blocks with second-level cement containers, while the cement containers in the second and third level blocks form three cement consumables, each of which is connected to the cement dispenser by screw feeders.

Between the unit with the boiler installation and the unit with consumable containers for chemical additives, the compressor and the loading conveyor, an inclined conveyor for unloading the finished product is installed, the lower end of which is located under the mixing apparatus.

All units and the control panel are interconnected by a quick-disconnect system of electrical wiring and a quick-detachable system of pipelines and hoses.

The control panel is located in a separate room of the lower tier block and is equipped with a computer to provide automated control of the operation of technological equipment and to monitor its functioning.

The invention is illustrated by drawings, which depict: in Fig.1 schematically shows a modular plant for the production of concrete and mortar; figure 2 is a view of figure 1; figure 3 is a view of B in figure 1; figure 4 is a view In figure 1; figure 5 - section GG in figure 1.

The modular plant contains 8 quick-detachable and quickly mounted box-type blocks mounted with a U-shaped arrangement of blocks in a horizontal plane. Blocks are installed on one common foundation and are located on three levels. In separate blocks is placed technological equipment for the production of concrete and mortars.

Two blocks 1, 2 are placed in the upper level, three blocks 3, 4, 5 are placed in the middle level, three blocks 6, 7, 8 are also located in the lower level.

The frame of each block is formed of welded metal frames. The blocks are bolted to each other.

Blocks 1, 2 of the upper level and blocks 3, 4 of the middle level have containers for cement 9, 10, 11, 12, 13. Tanks for cement located in the upper and middle levels form three cement hoppers 14, 15, 16, each of which has a lower contracting part in communication with the cement batcher by means of screw feeders 17.

In block 4 there is also a consumable container 18 with water.

In block 5 of the middle level are located feed bins 19, 20, respectively, of sand and gravel.

In block 7 of the lower level installed boiler room 21.

In block 8 of the lower level, consumables 22, 23 for chemical additives, a compressor 24 and a conveyor-dispenser 25 of sand and gravel are placed.

In block 6 of the lower level there is an operator compartment 26 with a control panel 27, a mixing apparatus 28 and a cement dispenser 29 located above it, connected to cement consumables through screw feeders, as well as a water dispenser 30 and a chemical additive dispenser 31 are installed.

The control panel 27 is equipped with a computer to provide automated control of the operation of technological equipment and to monitor its functioning.

Between block 8 and block 7 there is an inclined conveyor 32 for unloading the finished product, the lower end of which is located under the mixing apparatus 28.

Installation of the plant is carried out on a prepared foundation (foundation) using a crane.

Blocks with technological equipment pre-installed in them are sequentially mounted in the first, second and third levels, fastened together by bolted connections. All units and the control panel are interconnected by a quick-disconnect wiring system and a quick-detachable system of pipelines and hoses.

The plant operates as follows.

Sand and gravel pre-loaded into the supply hoppers enter the conveyor-batcher and then into the mixing apparatus. Cement pre-loaded into consumable hoppers through screw feeders enters the dispenser and then into the mixing apparatus. Water and the necessary chemical additives are supplied to the mixing apparatus from the respective consumables by means of electric pumps. In the cold season, sand, gravel, water are heated by steam from the boiler room or by steam from an external source.

Executive pneumatic mechanisms of the equipment are driven by air from the compressor.

The operation of technological equipment located in separate units is controlled automatically or manually from the operator’s console.

The proposed block design allows quick and efficient installation and dismantling of the plant.

The proposed plant has a compact structure with small dimensions and weight, which can be mounted both in an open area and in a closed hangar.
