Definitions

• the invention relates to pressing devices of presses for special Areas of application, in particular press screws for pulling Oil from oily raw material.
• the manufacturing technology of the well-known snail and the technology the repair in the event of operational wear however, is a complex of difficult operations that the Use of equipment with high precision and highly qualified Require work in multiple areas.
• the production of a new one or the restoration of a worn one known snail up the proportion of metal waste 90% of the mass.
• the manufacturing technology of the snail as the closest State of the art is considered much easier in Comparison to the one-piece screw. Is simplified also the technology of repairing such, in Operation worn snail.
• snail and its repair are also difficult technological operations linked to the use of Devices with high precision and the execution of highly qualified Require work.
• the metal losses remain relative high: achieve the metal losses in the production of the screw 60-70% of the mass.
• the task is solved by a press screw, the in the form of a bushing set arranged on a shaft Worm thread and smooth intermediate bushes, the bushes with worm thread and the smooth intermediate bushes in the form of packages composed of individual slotted spiral washers with different outer diameters are formed, which have a pitch that is the same the pitch of the worm thread.
• the snail according to the invention by the distinguish closest prior art, along with the common features of the snail according to the invention and the closest state of the art ensure better production-oriented production of new and better production-oriented Repair of worn snails simultaneous reduction of material losses in all cases, to which the claimed legal protection extends.
• the drawing shows an overall view of a particular embodiment the snail according to the invention.
• the press screw comprises one on a shaft 1 with a collar 2 attached flat through disc 3 and single composite slotted spiral disks 4, 5, 6, 7 and 8.
• Das Package of spiral washers is through a locking ring 9, a Jack 10 and a flat clamping plate 11 completed.
• the package is secured by a clamping bolt 12 on the Wave 1 fixed.
• spiral disks 4, 6 and 7 form the screw body.
• spiral disks 5 also form its feed thread.
• the spiral disks 8 form next to the screw body also its press thread.
• the snail described is one in a colander drum pressing press (not shown in the drawing).
• a colander drum pressing press (not shown in the drawing).
• the screw leads the feed thread of the spiral disks 5 the oil-containing raw material that has entered the colander drum Axial direction of the shaft 1 to the press thread of the spiral washers 8, which press the oil-containing raw material and push the oil out of it.
• the locking ring 9 regulates the pressure of the pressed Raw material.
• the oil pressed out is in a special Collecting pan of the press, and the pressed material is brought out in the form of a press cake in the axial direction from the press.
• the structure of the press screw according to the invention for pulling oil from oily raw material allows the most important sections the snail in the form of individual composite slotted To produce spiral disks by simple forming. With wear individual sections are simply replaced by appropriate ones Spiral disks replaced, and worn spiral disks with Larger outside diameters can be easily turned on a Thread lathe instead of worn spiral washers smaller outer diameter are used, the corresponding Have gear.
• the press screw according to the invention can even be used in smaller ones agricultural workshops with limited machinery be made and repaired.
