RU61635U1 - TAPE-ROLLER PRESS FOR SPINNING OF BEET CHIP - Google Patents

Abstract

The utility model relates to the processing of wet, solid plant materials and can be used to process beet pulp in order to better dehydrate it before being fed to the dryer.

The belt-and-roller press for squeezing beet chips consists of two belt-and-roller devices: the first is for preliminary squeezing of beet chips, consisting of a drive conveyor with an endless filter tape installed in the drive zone with a varying clearance of pressing elements, and the second is for the final squeezing of beet chips , consisting of a drive conveyor with an endless filter belt installed in the pressing zone of a movable plate with rotating rollers and a varying gap, of a collector pulp press water.

The technical result of the utility model is to simplify the design of the known press, which entails an increase in the moisture yield of beet chips, which reduces energy consumption for drying it, it is stored longer, which is especially valuable for agriculture.

Description

This utility model relates to the processing of wet, solid plant materials and can be used to process beet chips with the goal of better dehydration before being fed to a dryer used in the food industry.

Known tape dehydration device containing a pair of strip-like tapes of filter cloth. The tapes are mounted rotatably and have opposing surfaces, forming a gap between them for transmitting wet solid materials. The device also comprises means for establishing various rotational speeds and means for vibrating at least one of the tapes in the transverse direction to the tape (Patent of the Russian Federation RU 2149164 C1, published on 05.20.2000).

The disadvantage of this device is the lack of compression of beet chips, the complexity of the design, which entails a decrease in the efficiency of the filter tape, excessive humidity of the beet chips.

The closest in technical essence is a press for squeezing shredded plant materials, including a frame on which drive drums are mounted, three pairs of vertically mounted press rolls, electromagnetic vibrators, juice collectors. The filter belt is pulled onto the drums using chains. The chains slide along the grooves of the guide tubes. The guide tubes come together in a pressing zone so that it takes a V-shape, with the rollers mounted vertically on both sides of the conveyor and in contact with a sagging filter tape, which is also a filter. The distance between the guide tubes in the pressing zone

gradually decreases, as a result, the sagging of the tape between their edges increases. In the pressing zone, after the first and second pairs of rolls, pipes with holes for supplying water and secondary juice are installed. A scraper and a pulp collector are mounted on the frame. In the proposed press, pressing occurs not by volume, but along the contact lines of the raw material with each pair of rolls. In this case, the spin force is significantly reduced, and the juice yield increases, since its swelling occurs under its own weight on a vertical plane. (Patent of the Russian Federation RU 2062700 C1, published on June 27, 1996)

The disadvantage of this press is the intensive wear of the tape, which is a filter element, which results in frequent replacement of the filter element, increased metal consumption of the structure and a significant effect on the structure of the product, which is unacceptable for crimping beet chips.

The purpose of the proposed utility model is to achieve optimal physical and mechanical structure of beet chips before it is fed to the dryer by introducing two pressing zones - a belt-roller press for preliminary pressing and a belt-roller press for final pressing, and an adjustable pressing force.

This goal is achieved by the fact that in a belt-roller press for pressing beet chips, a system consisting of two belt-roller devices is installed: the first is for preliminary pressing of beet chips, consisting of a drive conveyor with an endless filter tape installed in the drive zone with a variable gap pressing elements, the second - for the final extraction of beet chips, consisting of a drive conveyor with an endless filter tape installed in the pressing zone of the movable oh plate with rotating rollers and a varying gap, a bag of pulp press water.

In the figure, representing the belt-roller press for squeezing beet chips, consisting of:

1. Tape-roller device for preliminary squeezing of beet chips;

2. Tape-roller device for the final squeezing of beet chips;

3. Forming plate;

4. Pressing elements;

5. Movable frame with adjustable clearance;

6. Infinite filtering tape;

7. The frame.

Tape-roller press, represents two tape-roller devices for preliminary extraction and for final extraction, respectively. Unpressed chips along the guide tray are fed to a belt-rolling device for preliminary pressing (1), where, using a forming plate (3), it is applied to the pressing elements (4) in an even layer. The resulting water enters the pulp press water collector, and the pre-squeezed beet chips are fed to the belt-roller device for final squeezing (2), where it falls under the movable frame (5) with an adjustable gap. The squeezed water, passing through the filter element (6), enters the collector of pulp press water, and then is reused at the enterprise, and the squeezed beet chips enter the dryer. On the device for the final squeezing of beet chips, on the idle branch of the filter element, scrapers are installed to remove the remains of beet chips.

The proposed press proposes combining the transportation of the product with the technological operation - extraction, which significantly reduces the cost of conveying equipment.

The advantage of the proposed design is the lower metal consumption and simplicity of the technology for manufacturing parts and assembly units, which significantly reduces the cost of manufacturing the structure.

The technical result of the utility model is to simplify the design of the known press, which will entail an increase in moisture yield of beet chips, thereby reducing energy consumption for drying beet chips.
