SK29894A3 - Device for washing of sugar beet - Google Patents

Abstract

The subject of the invention is an apparatus for washing beet which is made up of an elongate rotary drum with a perforated wall and is fitted on the inside with screw conveyors or blades which carry the beet from one end to the other, and with sprinkler pipes having nozzles which spray water under pressure onto the beet. With a view to using an apparatus of this type for the final washing of beet in the washing station of a sugar refinery, and providing better cleaning of the sugar-containing grooves than is obtained with conventional apparatuses, the drum has on its inside surface low humps (48) and the dimensions of the apparatus and its method of operating are chosen to ensure that the beet (26) is conveyed in a single layer. <IMAGE>

Description

Fields of technology - the state of the art

BACKGROUND OF THE INVENTION The present invention relates to an apparatus for washing sugar beet comprising an elongated rotary drum with a horizontal axis, the walls of which are perforated and which is internally equipped with helices or blades to move the sugar beet balls from one end to the other. which spray water under individual sugar beet cells. Similar equipment is usually used in sugar refineries as an entrance device in a washing hall for the removal of sugar beet.

So far, the washers, which, however, washed sugar beets. ensure final washing purification of sugar grooves this operation used vibrating could not provide the required degree

The device according to the invention would have sugar beet, especially better

SUMMARY OF THE INVENTION

The device according to the invention is characterized in that the drum has protrusions on its inner surface of a slight height (less than 10 mm) and the dimensions of the drum as well as its equipment are designed so that the displacement of the sugar beet balls is possible in one layer. The protrusions then cause the eyeballs to flip, so that their entire surface is sprayed with jets of water, which also penetrates into the sugar fibers and thus cleans them. These protrusions may be e.g. formed in the form of ribs parallel to the drum axis.

Preferably, the drum walls are formed of perforated sheet metal,

2 which is lined with rubber panels which are also perforated and on which the protrusions are arranged. These panels may be self-supporting, e.g. the rubber frame may be embedded in the metal frame. The panels are mounted on the side wall of the drum to avoid contact of the sugar beet balls with other fasteners. This creates a space between the panels and the sheet which allows the washing water to drain.

for beds, screws and

For the purpose of shifting the beet in one layer, the apparatus is equipped with a drum rotation drive mechanism which allows the rotation rate to be controlled with respect to the amount of beet processed.

Overview of the figures in the drawing

In the following, the description refers to the accompanying drawings, which illustrate an embodiment of the invention and do not limit its scope in any way.

Fig. 1 is a front view of a washing drum according to the invention; Fig. 2 is a cross-sectional view of the drum of FIG. 1; Fig. 3 is an enlarged perspective view of a portion of the drum wall; FIG. 4 is an enlarged view of how the panels are mounted on the metal ring of the drum.

DETAILED DESCRIPTION OF THE INVENTION

The washing device shown in the drawings consists of a longitudinal drum with a horizontal or slightly inclined axis. The drum consists of cells with a full wall and cells with a perforated wall. The two full-wall members 12 and 14 positioned at the ends of the drum form a conveyor belt with rollers 18 which support the drum and set it in rotation.

Between the links 12 and 14, the drum is formed by three perforated links 20 separated by short links with a solid wall 22.

The ramps equipped with the washers 24 are arranged inside the drum along its entire length, thus allowing spraying of the water under pressure onto the sugar beet cells 26; the position of the frame and the inclination of the windscreen washers can be adjusted.

Through the delivery device 28, the sugar beet cells reach one end of the drum. The perforated ring member 30 located at the other end of the drum allows the sugar beet to drip.

Funnels for trapping the water burdened by clay and dirt 32 are located below each of the links 20.

The links 20 are connected by a metal perforated ring 34 coated on the inside with panels 36 with apertures that are arranged on most of their surface to form the presievacle panels. These panels consist of a lattice mounted on a metal frame and rubber-coated, just like a frame.

The fastening of the panels 36 to the ring 34 is secured laterally by the beds 40 and the pins. The wedges 44 create a space 45 between the panels and the ring to allow water to drain through the panels and holes in the ring. For the same purpose, the panels can be provided with protrusions 46.

The surface of the panels 36 is formed by ribs 48 parallel to the axis of the drum, thereby forming longitudinal protrusions at a slight height and allowing the carbohydrate grooves 50 to be cleaned in the cells and also rotated while remaining in the drum.

are ribs

However, in the example shown, which is designed as a continuous strip, they can also be cut or replaced by rows of points or teeth; however, in all these cases, the height of the protrusion on the inner surface of the panels is less than 10 db.

In addition, the drum is equipped with screwdrivers which are not shown and which in a known manner provide for the movement of individual sugar beet balls from the inlet to the outlet of the machine. These helixes are designed to ensure the transfer of sugar beet in one layer. Both the respective dimensions of the drum and the working speed have been deliberately chosen to allow a function of the device that would correspond to the feed of the processed material. The drive mechanism which drives the drum 52 is provided with a continuous gear 54, which allows the sugar beet layer to be optimized.

It is to be understood that all modifications that may be made to the described embodiments of the invention with the aid of technical equivalents are within the scope of the invention.
