Description

The invention relates to a technology for the production of building materials, specifically to devices for slaking lime and the preparation of lime paste.

A device for the manufacture of lime paste according to A. St. USSR No. 1076409, containing two containers, and one of them (internal) is embedded in the external. The inner container is perforated and connected to a vibration generating mechanism. Milk of lime accumulates between the two containers and is pumped out from there. Impurities are periodically removed from the internal container. The process of extinguishing lime in this case occurs discretely, so the installation has a low productivity.

Known installation for extinguishing lime according to the patent of the Russian Federation for the invention No. 2064904, containing a stirring mechanism and a filter.

The disadvantage of this installation is a very small percentage of finished products.

A known installation for the manufacture of lime paste according to the patent of the Russian Federation No. 2158240. This installation contains a mixing device, a pre-filter, an intermediate container, a pump, a filter and a settling tank, while the settling tank is made in the form of a container with an opening in the lower part, in which a water-permeable fabric bag is placed.

The disadvantage of this device is its low productivity, due to the duration of the process of water separation. The performance of the water separation process is limited by the surface of the fabric permeable bag, the bore between the threads of the fabric from which this bag is made, and the hydrostatic pressure inside. Changing the hydrostatic pressure of a lime mortar inside a fabric permeable bag is a real, but technically difficult task, realizable with a significant complication of the installation.

The objective of the invention is to increase labor productivity.

The stirring device may be perforated.

Option 2

Installation containing a mixing device, a pre-filter, an intermediate container, a pump, a filter and a settling tank with an opening for draining water at the bottom and a fabric permeable bag, the settling tank is made of an oblong shape in plan, one or more are suspended above it with the possibility of horizontal movement several additional fabric permeable bags, fabric permeable bags have the ability to move horizontally and contain valves. The installation uses a container for collecting lime paste.

For all options, the settling tank can be made in a horizontal cross section of a rectangular or square shape. A hole for draining the water can be made in the lower end or on the side wall of the tank. The system for draining water from a hollow perforated cylinder can be connected to its upper or lower end face of the hollow perforated cylinder and contain a pipeline. The water drainage system may comprise a pump out. The connection of the pipeline with a hollow perforated cylinder, it is advisable to perform telescopic.

An intake pipe 10 is lowered into the intermediate container 7, to which the joint pump 11. To the output of the pump 11 pumping docked line 12. By leaving the transfer line 12 positioned settling tank 13 with aperture A formed on the bottom (Figure 1) or sideways (Figure 5). The settling tank 13 can be made of any shape, for example, cylindrical (Fig. 4), rectangular or square cross-section (Fig. 5), or trapezoidal in cross-section (Fig. 6). A permeable fabric bag 14 is placed inside the settling tank 13, and an inner permeable fabric bag 15 is placed inside the permeable fabric bag 14, a hollow perforated cylinder 16 is placed inside the inner permeable fabric bag 15, which contains the water drain 17. The water drain 17 can include a pump 18 , the pipe 19, and the connection of the pipe 19 with a hollow perforated cylinder is made telescopic (Fig.7).

The device for mixing is made perforated with holes 21.

2nd option

The installation according to the second embodiment (Fig. 3) contains a stirring device 1, inside which quicklime is poured 2. In the lower part of the stirring device 1, a valve 3 is made, to which a drain pipe 4 is attached. A water supply pipe 5 s is installed in the upper part valve 6. Below the mixing device 1, an intermediate container 7 is made, on which an intermediate filter 8 is installed for separating solid particles of impurities 9. An intake pipe 10 is lowered into the intermediate container 7, to which the joint pump 11. To the output of the pump 11 pumping docked line 12.

And are made with the possibility of horizontal movement using a cable block system 24. Outside the settling tank 13, a container for collecting lime paste is installed.

Device operation

1st option

During operation, quicklime is pre-poured into the mixing device 1, then water is poured through the water supply pipe 5 through valve 6. The agitator 1 rotates. In this case, quicklime 3 is quenched. The lime mortar through valve 4 and the drain pipe 5 are discharged to an intermediate filter 8, where solid particles of impurities are filtered, and a clean lime solution is pumped through a pipe 11 to a pump 10 and then to a settling tank 13 via a pressure pipe 12. more precisely, into a fabric permeable bag 14, through which water enters the settling tank 13 and then through the opening A in the lower part to return to the cycle or disposal. Part of the water passes through the inner fabric permeable bag 15 and through the holes in the inner hollow perforated cylinder 16 and further into the drain line 17. As a result, a calcareous paste forms between the two fabric permeable bags 14 and 15. The fabric permeable bag 14 together with the internal fabric permeable bag 15 and the hollow perforated cylinder 16 are removed from the settling tank 13. The presence of a telescopic connection facilitates this operation. Lime paste is packaged in plastic bags.

When working according to the first embodiment (Fig. 2), quicklime 2 is pre-poured into the mixing device 1, then water is added through the water supply pipe 5 through valve 6. The agitator 1 rotates. In this case, quicklime 2 is quenched. The lime mortar is discharged through openings 21 to an intermediate filter 8, where solid particles of impurities 9 are filtered, and a clean lime solution is piped 10 by pump 11 and then fed via pressure pipe 12 to a fabric permeable fabric bag 14, through which water goes inside the settling tank 13 and then through the hole A in the lower part to return to the cycle. The paste is packaged in plastic bags.

2nd option

During operation of the installation according to the second embodiment (Fig. 3), quicklime is pre-poured into the mixing device 1, then water is added through the water supply pipe 5 through valve 6. The agitator 1 rotates. In this case, quicklime 3 is quenched. The lime mortar through valve 4 and the drain pipe 5 are discharged to an intermediate filter 8, where solid particles of impurities are filtered, and a clean lime solution is pumped through a pipe 11 to a pump 10 and then fed through a pressure pipe 12 to a fabric permeable bag 15 through which water enters the settling tank 13 and then through the hole A in the lower part to return to the cycle or disposal. Since the installation provides additional fabric permeable bags 22 and a cable block system 24 for moving them, water is separated simultaneously in several additional fabric permeable bags 22. From the additional fabric permeable bag 22, located above the collection capacity of the lime paste 25, unload through the valve 23 lime paste.

Lime paste is packaged in plastic bags.
