Description

Centrifuges with a very large number of revolutions and low productivity are known, for example, tubular or supercentrifugal, copra has a small efficiency factor.

The described circuit fan-filter is distinguished by its design. from the well-known in that it is in terms of dimensions and other parameters similar to a vertical centrifuge with a lower drive, but it has the advantages of:

a) in order to combine the process of settling and filtering the suspension, inside the conical rotor, the conic is concentrically strengthened; Th; perforated 1 vessel with a fitting of this tement;

b) in order to filter the suspension under pressure, the rotor and vessel covers are sealed;

c) to carry out a process in the centrifuge, with a pressurized filtering system under pressure, a T-shaped branch pipe is placed in the center of a conical vessel, the horizontal sections of which will be drawn out to the surface of the breaker flange, and the vertical axis is enclosed in an omental seal;

d) for the purpose of episodic unloading of solid sediment from the filter and the rotor walls, during the rotation of the zeitrip, a mechanical discharge was applied through the valves in the bottom of the rotor.

The proposed centrifuge filter is original, both in its design and in the method of filtration, which takes place after preliminary settling due to centrifugal force and pressure in a closed centrifuge rotor.

FIG. I shows a sectional view of the centrifuge and fig; in fig. 2 - diagram of the device control the drain valves.

The centrifugal filter’s vertical settling unit consists of the following main elements: a cover L with a cover 2, which is made on three ball suspension supports 3 rigidly fixed to the plate 4. Insert a cone-shaped drum 5 with a vertical shaft 5 the rotor 6, closed hermetic cover 7.

The drum is equipped with a conical perforated vessel 8, on which a removable filter element 9 with a flange flange Y is put on.

The vessel with the filter element at the top and bottom is tightly attached to the lid and bottom of the drum-rotor 6. The belt drive 7 / centrifuge filter with the sub-Jnile jlita is rigidly fixed in the bottom of the casing /.

In the upper part of the conical vessel 8, a T-shaped branch pipe (V) is mounted, which serves to inject the suspension when the centrifugal rotation and the liquid flow are of peripheral speed equal to the circumferential speed of the drum-rotor, which is one of the centrifuges described.

The T-shaped pipe 13 is connected through the gland 14 to the fixed and salted pipe 15. Through this pipe and the pipe 13 and the centrifuge is in full swing, the suspension is fed into the drum-rotor, which will return its entire volume.

Under the action of centrifugal force, the slurry suspension / 5 is suspended to the outer wall of the drum and accumulates at the bottom of the base of the cone.

When creating the proper pressure in the Barbara-rotor, the enclosed part of the suspension continuously passes through the filler cell /, flows down and is continuously removed through the opening J6 in the bottom of the cone vessel and the drum-rotor.

By increasing or decreasing the pressure and suspension of the suspension in the drum drum-rotor, it is possible to regulate within certain limits, both when the centrifuge is used and the degree of transparency of the centrifuge.

Filtered filtering as it scans in the Arabian-rotor is periodically removed through the hole 17 in the bottom.

FIG. 2 schematically depicts a centrifuge drum-rotor, with cranes 18 with hinged levers 19 mounted to which are attached straps 20, interconnected with a coil 21, which moves freely up and down through pipe 15, under the action of a lever plate 22, between rollers 23 which freely inserted upper disk reel.

Subject invention

1. Vertical otteoya centrifuge-filter with a lower drive, consisting of a ciliydric casing, a mount of three three-ball suspension with supports, and a cone-shaped rotor with a lid mounted on a vertical shaft, o tl and hI hI a with Combining the process of otstupi and filtering the suspension under pressure, inside a hermetically sealed rotor, a conic hardened hardened vessel is concentrically strengthened, with a filter element with a flashing flange attached to it, on the upper surface of which is in the center of the vessel under A tempered branch pipe is inserted, the horizontal segments of which are brought to the back of the bumper flange, and the vertical axis of which is welded to the vessel lid at the bottom, and enclosed in the gland seal at the top.

2. Vertical settling centrifuge filter no. 1, characterized in that, for the purpose of occasional unloading of solid sediment from the filter element and the walls of the rotor or the rotor of the centrifuge, valves are used in the bottoms of the rotor.
