Definitions

  • the invention relates to a two-roll machine for the pressure treatment of granular material, in particular roller press for Gutbettzerklein ceremonies or compaction or briquetting, with two rotatably mounted, counter-driven and separated by a nip rollers, of which at least one is designed as transverse to the nip roller movable, wherein the Bearing housings are stored with their lower and upper sides on slideways of machine consoles, with the use of hydraulic cylinders for pressing one roller against the opposite roller.
  • the hydraulic cylinders which press on the bearing housing of the Loswalze, must be supported on solid side parts of the machine frame.
  • the machine frame forms a self-contained force system, ie occurring during operation of the roller press high radial roller press forces or grinding forces must be absorbed by the self-contained machine frame, which is heavy and expensive.
  • JP-H-09192519 discloses a two-roll machine with rotatably mounted, counter-rotating driven and separated by a nip rollers.
  • the bearing housings are mounted with their lower and upper sides on slide tracks.
  • the two-roll machine on hydraulic cylinders for pressing the rollers, which are arranged so that they attack the bearing housings of both rolls.
  • the construction is possible only with a high weight of the necessary for the transmission of hydraulic power link or lever.
  • the invention has for its object to design a two-roll machine, in particular roller press of the type mentioned above so that the machine frame is easy to build and lightweight and allows easy assembly and disassembly of the rollers.
  • roller press for Gutbettzerkleintation support the hydraulic cylinder with which the roll pressing force is applied to the compressive stress of the nip located in the nip, not on a heavy machine frame, but the hydraulic cylinders are arranged so that they both on the bearing housings which engage a roller as well as on the respective opposite bearing housings of the other roller to form a self-contained Mahlpress technologysystems, so that a closed loaded with the roller press forces machine frame is unnecessary.
  • This means, therefore, that the radial grinding forces are absorbed directly by the opposing bearing housings of both rollers that are opposite each other.
  • the hydraulic cylinders can be arranged transversely to the nip between the respective opposite bearing housings of the rollers, as a pull cylinder, which contract the opposite bearing housing and thus the two grinding rollers.
  • the hydraulic pull cylinder together with the bearing housings form a self-contained force system, which makes a heavy-duty machine frame superfluous.
  • a machine frame meet essentially machine panels with slideways on which the bearing housing with its lower and upper sides are slidably supported and which are able to absorb axial forces occurring in the roll operation.
  • the hydraulic cylinder instead of pulling cylinder but also be pressure cylinder which can be pressed against the bearing housings of a roller at its outer side facing away from the nip and their pressing forces across transverse to the nip pull rods on the respective opposite Transfer bearing housing of the other roller.
  • the hydraulic pressure cylinder and the bearing housing together with the tie rods in turn form the self-contained force system for receiving the radial grinding forces.
  • the two-roll machine according to the invention is in principle at any rate open to the side. In case of overload necessary evasive movements of the Loswalze or the Loswalzen are not hindered. Since heavy-weight end pieces of the machine frame omitted, the rollers z. B. replaced on the occasion of a repair without lengthy disassembly of the machine frame, d. H. dismantled and assembled.
  • hydraulic cylinders are each designed as double-acting cylinders, they can be used not only to apply the roller pressing force, but also to move the two rollers apart when the pressure medium is applied in the opposite direction.
  • both rollers can be designed as movable transverse to the nip roller bearing, whereby both rollers are equally loaded and a uniform wear of the roll surfaces is formed.
  • Both rollers may be supported by positioning cylinders mounted on the machine consoles, which can center the nip toward the center of the machine.
  • the working hydraulic cylinder is also possible to form the working hydraulic cylinder as a double-piston hydraulic cylinder with two independently acted upon with pressure medium working spaces and pistons which engage the respective opposite bearing housings.
  • the two bearing housings of one of the two grinding rollers can with their outer side facing away from the nip but also via fasteners such.
  • B. consoles so that this roller is then the hard roller.
  • These links are outside of the self-contained Mahlpress technologysystems and they in turn only prevent lateral slippage of the two rolls including bearing housings on their slideways of the machine consoles.
  • the roller press after Fig. 1 has no self-contained machine frame for receiving the roller pressing forces more, but the frame consists essentially only of two spaced transversely to the nip lying brackets 10, the tops have flat slideways.
  • Both rotatably mounted, in opposite directions driven and separated by the nip rollers 11, 12 are formed in the embodiment as transverse to the nip movable rollers.
  • Both rollers 11, 12 are mounted at both ends in bearing housings 13 and 14, which are mounted with their lower and upper sides on the slides of the brackets 10, 10a.
  • Both rollers 11 and 12 can with their bearing housings 13 and 14 on the slides of the brackets 10 transversely to the nip translationally back and forth.
  • the upper slide track guide of the bearing housings 13, 14 is indicated by the numeral 10a.
  • the connecting element between the upper and lower brackets 10, 10a is in Fig. 3 indicated by the numeral 10b.
  • the roller pressing force to the compressive stress of the nip located in the nip is to be comminuted according to the embodiment of Fig. 1 of a total of four hydraulic cylinders applied, of which in the front view of the Fig. 1 the two hydraulic cylinders 15 and 16 can be seen, which connect the opposing front bearing housings 13 and 14 directly to each other. That means, as well as out Fig.
  • both ends 17 and 18 of the upper hydraulic cylinder 15 are articulated as a joint bearing, as well as the lower hydraulic cylinder 16, on or in the respective opposite bearing housings 13 and 14.
  • the two hydraulic cylinders 15, 16 only a single central hydraulic cylinder could be arranged per roller end face.
  • the hydraulic cylinders 15, 16 are arranged so that they each act both on the bearing housings 14 of the one roller 12 and on the respective opposite bearing housings 13 of the other roller 11 to form a self-contained Mahlpress mechanisms, so that a loaded with the roller press forces heavyweight Machine frame is unnecessary.
  • Fig. 2 shows how z. B. the right roller 11 together with bearing housings 13 to the right side without hindrance through a machine frame on the consoles 10 can pull out.
  • the rollers are held by positioning cylinders 20 which are fixed to the machine consoles 10 and the cylinder tubes of the Actuate hydraulic cylinder 16 or other suitable component of the system to be able to center the system towards the machine center by operating the positioning cylinder 20, even during machine operation.
  • the positioning cylinder 20 adopting a control function can at the same time be hydropneumatic damping components for damping the vibrations and shocks arising during machine operation.
  • the bearing housing shape can be designed so that an optimal load distribution is ensured on the mounted in the respective bearing housing bearings.
  • the hydraulic cylinders are designed as flat pressure cylinders 22 which are pressed against the bearing housings 14 of a roller 12 at the outer side facing away from the nip and their pressing forces across transverse to the nip tension rods 23, 24 on the respective opposite bearing housing 13 of the other roller 11 transmitted.
  • the flat pressure cylinders 22 are each supported on a traverse 25 which is hinged to the outer ends of the tie rods 23, 24, whose inner ends are in turn articulated to the respective opposite bearing housing 13 of the other roller 11. Also in this variant of the invention eliminates a machine frame that would have to absorb the roll pressing forces.
