Description

The proposed limescale oil is intended for mechanical slaking of lime and can be used to prepare clay solutions, chalk pastes, etc.

For slaking lime and mixing it, in the solution of any consistency, both small and lump of boil can be loaded into the apparatus, and the shape and size of the clods, as well as the grade of lime, are not limited. The latter will only affect the quality of the lime test and the productivity of the unit.

Lime nebulizer is a metal welded body / (fig. 1) of cylindrical shape, consisting of two parts: a lower cone-shaped, called a working chamber in which, by means, and a double cone 2 mounted on a vertical rotating shaft 3 processing lime-boil in lime milk of the required thickness, and the upper, cylindrical, intended for loading lime-boil or other processed raw materials.

The upper part of the housing 1 ends with a removable cover 4 consisting of two halves made of cr: 01 galvanized iron. To load the limescale, one half of the caps is removed. 42

The lower cone-shaped part of the reservoir 1 is attached to the collector 5 for the solution by means of flanges. A pipe for draining the solution is connected to one of the openings of the collector 5 through the tee 6 (Fig. 2), and the other opening is plugged with a revision cover 7 on the wings.

Case 1 limestone mounted on a metal rack 8, to which it is attached at the top with the help of the rim 9, and in the cone-like part with the help of kerchiefs 10.

Racks 5 are mounted on the frame of the cart, made in the form of a frame on which the electric motor 11 is placed, bearings 12 of the horizontal shaft 13, having a clutch with the electric motor shaft through the coupling 14.

The working part of the apparatus is a double cone rotor 2 mounted on a vertical shaft 5. Below the rotor 2, the shaft passes through the bottom of the collector 5 by means of a stuffing box and ends with a bushing 16 fixed to the trolley frame. The upper end of the shaft 3 is enclosed in a bearing 17, mounted on a T-shaped frame, bolted to the housing cylinder with bolts in case of repair or replacement of the rotor.

On the upper cone of the rotor 2, profiled incisors are made, but 6 9

They are formed at the optimum cutting angle and have a tray-shaped recess for guiding the cut material from the upper base of the cone to the lower one. The incisors are arranged radially, slightly rounded to the base of the upper cone. On the surface of the lower cone of the rotor, multi-cut is cut (according to the number of incisors on the upper cone) spiral cutting, along one edge of the grooves of which fork-shaped ribs-ribs are provided, the purpose of which is to grind harder lime particles. The spiral cutting of the lower cone is intended to direct lime mortar from the bottom of the tank to the collector.

From the bottom, the rotor has two blades (agitators) placed in the collector and fixed on the lower cone.

The rotor receives movement from the shaft 3 through a pair of conical gears / 5, one of which is located on the horizontal shaft 13, and the second on the vertical shaft 3.

The process of mechanical slaking of lime is as follows.

After starting the limescaler, water is pumped into the upper tank, which is used to wash the rotor, the collector and the pipeline. After flushing all taps are closed, hoses are connected to the drains (or trays are installed) to direct lime mortar to the we.

Then, the conveyor belt 19 is activated, by which during all the time the machine is running, the lime is loaded into the upper part of the tank. At the same time, the faucet is opened to supply water to the tank, which, when properly adjusted to obtain a solution of adequate thickness, remains open for the entire period of operation.

Drain cocks are opened after the solution has received the required thickness in the apparatus. Density is determined by sampling from a special tube connected to a collection. Water is introduced into the tank above the center of the latter (near the shaft).

The rotor, which makes more than 1,500 revolutions per minute, creates an energetic circulation of water in the reservoir, as a result of which large lumps of lime-boilers disintegrate into smaller ones and, falling under the incisors and fork-like edges of the rotor, are processed into lime milk, which, being drained into Pits, after 6-12 hours. turns into lime paste. Stones and solids that have not been processed by a limescaler are removed during machine breaks and at the end of the work shift.
