RU2338598C1 - Centrifuge for liquid cleaning - Google Patents

Abstract

FIELD: food industry.

SUBSTANCE: device has a body, in which a bowl with drive placed on a shaft is fixed, it consist of two vertical and concentrate conic shells with perforation holes, which form ring-form space between the shells filled with a filtering agent. Also the device has a filler and delivery necks, lid and liquid collector. And the upper part of the space between the shells is blocked by a perforated grille, placed so that it can change the position from top to bottom. Besides in the external side of the bowl there is a conic coaster, the lower edge of which is fixed to the body at the level of the bottom edge of the delivering neck.

EFFECT: simplification of centrifuge running.

Description

The invention relates to the food industry, where it can be used for refining vegetable oil or for the chemical industry.

A centrifuge is known, including a housing mounted on a rotor shaft in it, consisting of two vertical and concentrically arranged shells having perforations and forming an annular cavity filled with a filtering element, a filler neck, a lid and fluid collectors (AS USSR No. 1514414 Cl. B04B 3/00, 11/00). The disadvantage of this centrifuge is the low quality of cleaning, caused by the insufficient length of the path of passage of the cleaned liquid. An increase in this length leads to a significant increase in the dimensions of the centrifuge.

The closest in technical essence is a centrifuge for cleaning liquids, including a housing mounted on it on the shaft of the rotor, consisting of two vertical and concentric conical shells, the inner of which has a perforation and forming an annular cavity filled with filter media, a filler neck , cover and fluid collectors (RU 2108169, class B04B 3/00, 11/00).

The disadvantage of this centrifuge design is that it is impossible to remove the spent filter element from it without removing the housing cover, which complicates the operating conditions of the centrifuge.

The present invention is to simplify the operation of the centrifuge.

The present problem is solved in that in a centrifuge for cleaning a liquid containing a housing, a rotor with a drive mounted in it on the shaft, consisting of two vertical and concentrically arranged cone-shaped different shells with perforation and forming an annular inter-shell cavity filled with a filtering element, a filler neck , a cover and a fluid collector, the upper part of the inter-shell cavity is blocked by a perforated grill, installed with the possibility of changing its position in height, while on the outside thoron conical rotor mounted pan, the lower edge of which is attached to the body at the lower edge of the unloading mouth.

The technical result is an increase in ease of use, is that the discharge of the spent filter element occurs under the action of centrifugal force in a closed cavity of the centrifuge housing without opening the housing cover. This eliminates the scatter of the used filter element.

The drawing shows a diagram of a centrifuge.

The centrifuge for cleaning the liquid contains a housing 1, in which a rotor 3 is installed on the shaft 2, consisting of two vertical and concentrically arranged shells - the inner 4 and outer 5, which form an annular inter-shell cavity 6, filled with a filtering element 7. The inner shell 4 in the lower part has a perforation 8, and the outer shell in the upper part - perforation 9. On the upper part of the housing 1 there is a lid 10 and a filler neck 11, and between the conical shell 5 and the housing 1 there is an annular conical tray 12 for I collect the liquid and the spent filter element, the lower edge of which is attached at the level of the lower edge 13 of the discharge neck 14. In the upper part, the inter-shell cavity 6 of the rotor 3 is covered by a perforated grill 15, which is mounted with the possibility of changing its height position by screw 16, and connected to the outer ring the capacity of the collection of purified liquid, a conical pan 12. The shaft 2 is connected by a transmission 17 to the drive 18.

The proposed conical centrifuge is designed for fine cleaning of dispersed systems, in particular soybean oil. Cleaning is due to the passage of oil through the zealite filter element, which filled the inter-shell cavity 6.

The centrifuge operates as follows. The oil enters the centrifuge through the filler neck 11, then through the perforation 8 of the inner shell 4 enters the intershell cavity 6. Under the influence of hydrostatic pressure forces and the projection of the portable inertia force on the direction along the generatrix of the cone, caused by the rotation of the rotor 3, mounted on the drive shaft 2, uncleaned the oil begins to advance in the space between the shells 4 and 5 (inter-shell cavity 6) occupied by the filter material. The oil passing through the filter element 7, through the perforation in the grill 15 enters the annular conical pan 12 and leaves the centrifuge through the discharge neck 14.

After the filter element 7 becomes unusable, the perforated grate 15 is lifted with a screw 16, the centrifuge drive 18 is turned on and the spent element through the gap between the grate 15 and the outer shell 5 enters the conical pan 12 and is removed through the discharge neck 14.
