Description

Centrifugal liquid cleaner.

The utility model relates to the field of separation of suspensions and emulsions in the field of action of centrifugal forces and can be used to clean oils, fuels and technical fluids from mechanical impurities and water in machine-tool, chemical, oil and fat, aviation and other industries.

The well-known centrifuge GTsN-911K, taken as a prototype and included in the SOG-913K liquid purification stand (see passport 75302.954.00.000 PS, p. 8-11), developed, 1st AOOT PITI-Tesar. The ShchP-911K centrifuge contains a rotor with a disk insert located in a sealed cap on a fixed axis, an impeller connected to the drive, and a pressure disk, a line for supplying the cleaned liquid, and a line for draining the cleaned liquid in communication with the pressure sensor.

A disadvantage of the known centrifuge is that, during the accumulation of a critical amount of sediment during the cleaning process on the outside surface of the hood, a deterioration in the quality of liquid cleaning occurs, and clogging of the plates in the plate insert by sludge begins, which complicates the cleaning of the centrifuge.

The objective of the proposed utility model is to improve the quality of liquid purification by ensuring that the centrifuge automatically stops when a critical sediment volume is accumulated in it.

The problem is solved as follows. A centrifugal liquid cleaner containing a rotor with a disk insert located in a sealed cap on a fixed axis, an impeller connected to the drive and a pressure disk, a line for supplying a cleaned liquid and a line for draining the cleaned liquid in communication with the pressure sensor is equipped with a warning plate. Plate signaling mouth 41

is poured in the lower part of the plate insert, and the area of the annular gap between the plate-detector and the inner surface of the cap should be not less than calculated by the formula:

where S is the area of the annular gap between the signaling plate and the inner surface of the cap, W is the critical sediment volume, N is the height of the plate insert, m

In Fig.1 shows a centrifugal liquid cleaner in the context. Figure 2 - diagram of the actuator with a pressure sensor.

The centrifugal liquid cleaner contains a hollow axis 2 located in a sealed cap 1, on which a rotor 3 is mounted, which consists of a sleeve 4 with an impeller 5 pressed into it and a disk insert 6, lower 7 and upper 8 bearings.

The impeller 5 is equipped with a pulley 9 connected to the drive 10. In the sleeve 4, grooves are made for passage of the purified liquid into the collection cavity of the purified liquid 11, where a pressure disk 12 is installed, which serves to drain the purified liquid to the consumer.

An alarm plate 13 is installed in the lower part of the plate insert, and the annular gap between the signal plate 13 and the inner surface of the cap 1 must be not less than calculated by the formula:

where S is the area of the annular gap between the plate-5; b signaling device and the inner surface of the cap,

s- n

W is the critical volume of sediment, N is the height of the plate insert, m

The centrifugal cleaner has nozzles 14 and 15, respectively, for connecting to the supply lines of the cleaned liquid and the discharge of the cleaned liquid. The drainage line of the purified liquid is in communication with the pressure sensor 16.

Centrifugal liquid cleaner operates as follows.

When the drive is turned on, the rotation through the impeller 9 of the impeller 5 is transmitted to the rotor 3. The liquid to be cleaned that flows through the nozzle 14 is untwisted to the angular speed of the rotor 3. Under the influence of centrifugal force, the particles of dirt settle on the surface of the disk insert 6 and on the inner surface of the cap 1, and the purified liquid passing through the poppet insert 6, the pressure disk 12, the hollow axis 2 and the nozzle 15, enters the purified liquid outlet, in communication with the pressure sensor 16.

When a critical volume of sediment accumulates on the inner surface of the hood 1, an annular gap is overlapped between the signaling plate 13 and the inner surface of the hood 1, as a result of which the liquid pressure drops in the purified liquid outlet, and the pressure sensor 16 disables the centrifugal cleaner 10 drive.

This design helps prevent deterioration in the quality of cleaning by timely stopping the centrifugal cleaner to clean it from accumulated sludge.
