Description

one

The invention relates to devices for processing green feed and can be used in the preparation of feed.

Apparatus for processing plant material is known, including roller electrodes, one of which is sectioned along the length, and voltage source 1

A disadvantage of the known devices is the high energy consumption of the process, low productivity due to the passage of current across the material layer, and low processing uniformity due to poor contact of the electrodes with the material layer with an uneven layer thickness across the flow gap.

The closest in technical essence to the present invention is an electroplasma isolator for processing plant material containing rollers with insulated electrodes located along their forming, connected to a voltage source through brushes and collectors 2.

A disadvantage of the known device is the uneven processing of the layer of material along the width of the stream due to poor contact of the electrodes with the mass.

The purpose of the invention is to increase the uniformity of material processing.

The goal is achieved by the fact that the electrodes are made in the form of flexible conductive cables, which are mounted on rollers with a gap relative to their surface using radially spring-loaded elastic suspensions and spring-loaded relative to suspensions along the forming rollers.

The electrolyzer contains cylindrical rollers 1 and 2, made of insulating material, pressure spring 3, collectors 4, 5 with plates 6, 7, current collecting brushes 8 and 9 electrically connected to a voltage source (not shown).

Along each roller, flexible electrodes 10 and 11 are installed in the form of metal ropes along equal angular intervals along the forming cylinders, which are mounted on elastic hangers, for example, retractable rods 12 connected to springs 13. The rollers are installed in axes of rotation in one plane so that the contact zone, each electrode of one drum enters in the middle of the insulating gap between the two electrodes of the second drum. A common drive ensures their rotation in different directions (one clockwise, the other against) with the same linear velocity of the cylindrical surface of the rollers, regardless of the varying size of the working gap. The electrodes of the rollers are powered through separate wires 14 connecting the electrodes at the moment when the corresponding plates run over the corresponding brushes. The electrodes are fixed relative to the suspensions by means of a spring 15 and have tips 16 and pins 17. The device operates as follows. The flow of plants oriented along the direction of movement (in the process of cutting and flattening, the orientation is achieved naturally without additional operations) is fed along the centerline between the rollers perpendicular to the axis of rotation of the rollers, captured by the electrodes at the initial contact angle in the hedgehog zone and gradually approaching planes of axes of rotation, are pressed in the contact zones of each electrode of one roller to the insulating part of the cylinder of the second roller in the middle of the gap between two blocks its nearest-electrodes. Thus, different potentials are supplied to different points along the length of the stream oriented along the plants, and therefore along the length of the stems. In the contact zone of the electrode with the grass layer, an increased mass density is created, as a result of which the contact resistance between the electrode and the grass layer and between plants is minimal in the height of the layer. In the middle zone between the electrodes, the grass layer does not condense; the contact resistance between the stalks and the leaves of different plants is higher by more than an order of magnitude compared to the contact resistance in the contact zone in the electrode. Due to this distribution of contact resistances, and also due to the fact that in the plant tissue of each plant, the resistivity across the fibers (stem) is several times higher than the resistivity along the fibers (the stem electric current passes between two nearest electrodes of different rollers from one contact zone to another in mainly along the stems of plants and does not have a closed path through the leaves. With an uneven height of the layer across the width of the stream in areas with an elevated layer height creates pressure higher, h In the remaining areas, the layer thickens more, which is required for flattening the plants and creating a reliable contact between them in such areas. At the same time, in areas with an increased layer height, the rods 12 are recessed more, compressing the spring 13, increase the gap, and the electrode gets the opportunity to create contact with the rest of the areas.When the height of the layer is leveling with the width of the flow, the electrode is straightened by the action of the springs 13 through the rods 12, by the action of its own elasticity and by the action of the tension spring 15 through the clamps 17 at the tip 16. When a hard foreign object or tufts of vegetable mass hit a roller exceeding the radial limit of the flexible electrode (5-10 mm), the device can increase the gap between the rollers (more than 20 mm) due to compression of the spring 3 of the upper drum 1. Making the electrode flexible with the possibility of copying a layer of plants across the width of the stream, it improves the uniformity of processing, and hence the quality, the invention. An electroplasmolizer for processing plant material, with The adhering rollers with insulated electrodes located along their forming, connected to a voltage source through brushes and collectors, characterized in that the electrodes are made in the form of flexible conductive cables that are mounted on rollers with a gap relative to their surface with using radially spring-loaded elastic suspensions and spring-loaded relative to the suspensions along the generator of the rollers.
