Abstract

The winding belt press for separating liquids from solid substances where pressing pressure is increased by gradual tensioning of freely wound coils of the press wires (2), between which the pressed medium (3) is sandwiched.

Description

Technical field

The invention relates to a winding belt press for separating liquids from solids in the field of water purification and treatment, in the manufacture of paper and cellulose in the chemical, food, mining and other industries.

Winder belt press

BACKGROUND OF THE INVENTION

Various types of presses such as chamber presses, vacuum presses, membrane presses, band presses are currently used for separating liquids from solids.

All have their advantages but also disadvantages in terms of acquisition costs, operating costs, output parameters and suitability of use for a given type of pressed medium.

SUMMARY OF THE INVENTION

The principle of the invention is a winding belt press, the principle of which is that the liquid medium flows between two screens which are wound or wound on a winding press roller (system - reel).

After the gravitational concentration, the pressing process is initiated, which consists in observing the loosely rotated threads of the pressing sieves between which the pressing medium is located.

As the threads of the press sieves are gradually obstructed, the pressure on the press medium is gradually increased, while the liquid component flows through the channels formed by the tread of the back side of the press sieves pressed against each other.

At the end of the pressing process, the press is emptied by reversing.

An advantage of the device according to the invention is that a large pressing surface (length of the wound sieve * width of the sieve) can be achieved on a device of small dimensions.

It is most advantageous to press the press sieves by blocking the auxiliary rollers and gradually increasing the torque of the winding press roll, whereby the press sieves are progressively moved away from the center of the winding press roll. The increase in ear forge can possibly be achieved by a bird of prey.

Overview of the figure in the drawing

BRIEF DESCRIPTION OF THE DRAWINGS The invention is explained in more detail with reference to the drawing, in which the drawing illustrates a device according to the invention in which the compression pressure is generated by progressively observing the loosely wound threads of the compression sieves between which the press medium is located.

Exemplifying the invention

The winding belt press according to FIG. 1 consists of auxiliary rollers 1, press sieves 2, a winding press roller 4, a pressure roller 5 and a scraper 6.

The press medium 3 is located between the press sieves 2, where, by mechanically locking the auxiliary rollers 1 and increasing the torque of the winding press roll 4, the press sieves 2 gradually follow from the center of the winding press roll 4, thereby gradually increasing the press pressure. An increase in the pressing pressure is achieved by pushing the pressure roller 5.

The take-up press roll 4, the auxiliary roll 1 and the press roll 5 may be in a vertical or horizontal position.

When the rollers 4, 5 are mounted vertically, a shrink seal is wound in the lower part between the press sieves 2 together with the sieves.

A shrink seal of a certain thickness ensures that a spiral chamber 7 is formed when the compression screens 2 are wound and sealed from the bottom by the seal. In the molding process, the shrink seal shrinks together with the molded material 3. The molded medium, when the cylinders 1, 4, 5 are vertically mounted, can flow into place 8.

With horizontal mounting of cylinders 1, 4, 5, no shrink seal is required.

The compressed medium 3 is scraped from the press sieves 2 by scraper 6 during reverse operation.

The device according to the invention can be used wherever a large pressing capacity is required with small dimensions of the device.
