Definitions
- the present invention relates to the mixing of a hydraulic binder and mineral materials with a liquid. It relates firstly to the use of a device comprising at least two concentric tubular elements, the external tubular element containing a helical drive means for liquids or solid products in the divided state.
- a device comprising at least two concentric tubular elements, the external tubular element containing a helical drive means for liquids or solid products in the divided state, for example in the form of grains and / or in the pulverulent state, said helical means surrounding the inner tubular element, the outer tubular element comprising at least one inlet for the liquid or solids and an outlet for the mixture of liquid and solids, said tubular member inside opening inside the external tubular element downstream of the inlet orifice and upstream of the outlet orifice.
- Such known devices are used for mixing and transporting solid products and liquids for further operation. There is no specification in these documents of a means of capturing these elements so as to form a new composition. There are also no plans to distribute the mixed products.
- the device as defined above is used to obtain a composition based on at least one hydraulic binder by semi-continuous mixing of the hydraulic binder with a liquid.
- the device is used for: - mix, transport and distribute a composition based on hydraulic binder, mineral materials and liquid;
- the invention also relates to an installation which allows use as defined above.
- Said installation comprises a device in accordance with that described above and it further comprises a mobile carriage supporting said device comprising feed metering devices upstream and a device for controlling and synchronizing the movement of the carriage as a function of the supply .
- This installation allows the supply and distribution of the hydraulic binder.
- it comprises a rotary element of revolution open at one end, said rotary element being concentric and of a diameter greater than the tubular elements of the device.
- the invention also relates to an internal coating process for a quick setting cement-based metal pipe.
- the coating is based on mortar containing a significant proportion of sand.
- the installation shown in the drawing comprises a device 1 formed by a tubular element 2 concentrically surrounding a second emerging tubular element 3.
- a helical spring 4 contained in the first tubular element 2 surrounds the second tubular element 3 for supplying water 5
- the first element tubular 2 has on the upper part of its circular envelope an inlet orifice 6a and at one end has an inlet orifice 6b, its other open end forms an outlet orifice 7.
- the tubular element 3 passes through the orifice 6b .
- Dry materials 8 made up in particular of minerals, for example sand and a hydraulic binder such as a cement, are brought through the orifice 6a.
- the mixture of dry materials 8 with water 5 forms a mortar 9 which leaves through the orifice 7.
- the device 1 is placed on a carriage 10.
- a rotary pipe 11 with an internal diameter greater than the external diameter of the first tubular element is disposed at the open end of the first tubular element 2 forming a distribution pipe.
- the pipe 11 is concentric with the tubular element 2 forming a distribution pipe.
- Dosing bodies 12 are connected to the upper inlet orifice 6a.
- a control and synchronization device 13 makes it possible to regulate the movements of the installation which comprises a motor 14 for setting in motion hollow rotary bearings 15 for driving the spring 4.
- Hoppers 16 containing either cement or different minerals such as sand is placed above the metering members 12.
- a pump 17 connected to the tubular element 3 makes it possible to supply the device 1 with water.
- the tubular element 3 opens into the tubular element 2 downstream of the inlet orifice 6 and upstream of the outlet orifice 7 so as to form downstream of the outlet of the element 3 a location 18 for mixing of dry materials with water and upstream a transport zone 19 and mixing of dry materials 8.
- the metering members 12 are fixedly connected to the carriage 10 by the device 1 and rigid pipes 20 for supplying dry materials.
- a deflector 22 is placed at the end of the spring 4. The installation distributes the mortar 9 in the pipe 11 through the distribution pipe 2.
- This operation is carried out by simultaneously ensuring the rotation of the pipe 11 on its axis 21, the translation of the device 1, and, the mixing, the transport in the rod 2 and the distribution.
- the helical spring 4 placed inside the rod 2 is driven by a rapid rotational movement.
- the dry materials 8 are introduced with the controlled flows in the zone 19 of the rod 2.
- the rapidly rotating spring 4 immediately ensures vigorous stirring which allows a perfect mixture of the different dry materials 8, as well as a transport of these materials in cane to location 18.
- the water 5 is injected via a second tubular element 3 into the location 18 of the feed rod 2.
- the rapid rotational movement of the spring 4 ensures a perfect mixture of the dry materials 8 with the water 5 as well as the transport of the mortar 9 then finished to the outlet orifice 7 of the cane 2.
- the movement of rotation of the pipe and translation of the cane ensures the immediate distribution of the mortar in the pipe 11 when it leaves the distribution cane.
- the deflector 22 allows a regular projection of the mortar 9 to form a uniform interior coating of the pipe 11.
- This installation has the advantage of being able to limit the quantity of wet mortar 9 present at all times in the installation with a location 18 of small dimension. So the residence time of this mortar 9 in the device 1 is reduced.
- This installation allows the use of very fast setting cements.
- the minimum setting time of this cement can be up to three minutes.
- mortars with a wide variation in rheology.
- the rheology of the mortar 9 varies according to the difference in dosage of some of the components with respect to each other.
- a composition 9 comprising water 5 cement and sand
- the mortar 9 will be very dry
- the solid materials (sand, cement) 8 will fall to the bottom and water 5 will rise to the surface.
- S / C ratio of 0 to 10
- S being sand and C cement are also located in a W / C ratio of 0.1 to 2.
- E water 5 and C being cement.
- the installation makes it possible to prevent the mortar 9 from settling because it does not produce pressure and stirs said mortar.
- This installation allows, for example, to distribute very dry mortars, mortars containing a large proportion of sand and mortars with a strong tendency to segregate.
