Definitions

  • the free end of the unit can be releasably engaged with a respective rotor or a plate mounted fixedly on the shaft of the rotor and provided with circumferentially spaced apertures for connecting purposes.
  • operation of the cylinder and piston unit serves to displace the rotor angularly to a desired angular position.
  • the present invention relates generally to comminutors, and more particularly to impact comminutors.
  • Impact comminutors are already known in a variety of different types and constructions. Some of these are in form of hammer mills and others are in form of impact comminutors, but they all use one or more rotors which turn in a housing and with which the material rocks and the like comes in contact to be impacted and crushed.
  • an object of the present invention to provide, in an impact comminutor, a construction in which the rotor can be readily positioned in a desired angular position and can be arrested in the once-assumed angular position.
  • a concomitant object of the invention is to provide such an arrangement which is very simple in its construction and operation, and which requires very little space.
  • Still a further object of the present invention is to provide such an arrangement which is highly economical in its construction and can, according to an embodiment of the invention, be used with two adjacent rotors in cases where the comminutor has two or more rotors.
  • an impact comminutor having a combination of wall means defining an interior chamber and rotor means mounted for rotation in this chamber.
  • a cylinder and piston unit has a first end and a second end, mounting means being provided which pivotaIly mounts the unit on the wall means laterally offset from the rotor means.
  • Releasable connecting means is provided for releasably connecting said second end of the unit with the rotor means in order to move the latter to a desired angular position in response to operation of the unit.
  • FIGURE is a somewhat diagrammatic end-elevational view of a comminutor embodying the invention.
  • the invention has been illustrated by way of example in an impact comminutor of the type provided on its rotor with a plurality of beater bars which extend longitudinally of the axis of rotation of the rotor. It is, however, equally applicable to any other type of comminutor having one or more rotors as was already pointed out.
  • the invention has been illustrated in the form of an impact comminutor having two adjacent rotors; the invention is, of course, applicable also to impact comminutors having only a single rotor or to impact comminutors having more than two rotors.
  • the drawing shows an impact comminutor having a housing 1 bounded by wall means 1.
  • rotors 10 mounted for rotation in the housing 1, that is in the interior chamber thereof, are two diagrammatically illustrated rotors 10, which are shown in chain lines and provided on their peripheries with beater bars 100. These rotors turn about axes 4 which in this embodiment extend in parallelism with one another and are transversely spaced from one another.
  • the illustration is such as to show the end wall of the housing 1, provided with a pair of access openings 1" through which access is to be had to the beater bars 10a. Consequently, the beater bars 10a, which are located in registry with the respective openings 1" are shown in full lines, whereas the other and the remainder of the respective rotor 10 are shown in chain lines.
  • Each of the rotors 10 is provided with a disc-shaped member 3 which is mounted outside the chamber on its respective shaft constituting the axis of rotation, with the members 3 being fixed with the shaft and rotatable therewith.
  • Each of the members 3 is provided with a plurality (here four) of openings 5, which in the illustrated embodiment are equi-angularly spaced. Of course, more or fewer than these openings could be provided and they need not be equi-angularly spaced.
  • a cylinder and piston unit 2 which shall be assumed to be hydraulically operated but it could also be operated otherwise.
  • the unit 2 has two opposite ends a first one of which is connected by suitable mounting means 1a (a pivot or the like) to the wall of the housing 1 so that in its normal rest position in which it is not used, the unit 2 will depend under the influence of gravity from the pivot provided by the mounting means 1a in the chain line position.
  • the opposite or second end of the unit 2 is provided with an eye or aperture 6.
  • the unit 2 When the respective rotors with which the unit 2 can selectively be connected are to be turned to a desired angular position the unit 2 is connected with the respective member 3 by for instance passing a pin or other connecting means 6a through one of the openings 5 and through the eye 6 of the unit 2. Thereafter the unit 2 is operated in a sense extending or retracting its piston rod whereby the rotor coupled with it can be turned either in clockwise or in counterclockwise direction until the beater bar 10a or analogous element which is to be inspected or engaged through the respective opening 1 will be juxtaposed with the latter.
  • the openings 5 could also be provided directly on the respective rotor 10, and that instead of the openings 5 (either on the member 3 or on the rotor itself) other connecting means could be provided for instance projections or the like.
  • the unit 2 is pivoted about the point 1a towards that one of the two rotors with which it is to cooperate, in the illustrated embodiment to the left-hand one, until it is in the full line position shown. Because the point 1a is located equi-distantly between the axis 4, the unit 2 will normally depend between the two members 3 out of contact with both until such time as it is to be used.
  • the unit 2 may be operated, for instance, by means of a foot-actuated pump 9, with which it is connected in suitable manner via the illustrated (no reference numerals) hydraulic lines.
  • the mounting of the unit 2 can be reversed and the eye 6 can be connected to the wall 1' by the mounting means la, whereas the other end portion can be releasably connected with the respective rotors.
  • an arresting device 7 having, in the illustrated embodiment, at least one or two transversely spaced lugs 7 the single lug 7 is formed with an opening 8 or, if two of the lugs are provided transversely spaced from one another, there are two openings 8 provided which are in registry with one another.
  • the lugs 7 are so located that they overlap the members 3 as illustrated, and of course, if there are two of the lugs 7 provided then the respective disc member 3 will be located between them.
  • the openings 8 are so located that the openings 5 of the associated disc-member 3 can be placed into registry with the respective opening or openings 8.
  • arresting can simply be carried out by inserting a pin or the like through the registering openings 5 and 8, thereby preventing the rotor N) from turning and retaining it in the selected angular position until such time that the ball or pin is withdrawn.
  • Disc-shaped member 3 may be in the form of a single disc or two parallel discs, the latter thus aligning the pins or other connecting means 6a with opening 8 in lug or lugs 7 or with eye 6 more accurately.
  • the cooperating impact units l0b have also been illustrated which cooperate with the rotors 10 and on which material flung by the rotors and flung against the units 10b, will crash to fall back on the rotors and obtain additional impacts in the sense comminuting it.
  • These units 101) have been shown only for orientation and do not form part of the present invention, being entirely conventional in the impact-rebound type of comminutor.
  • the present invention achieves the afore-mentioned objects and does so in a simple and reliable as well as expedituous manner.
  • the space requirements of the novel arrangement are very small, and on the other hand, manual turning of the rotor is no longer necessary.
  • the rotor can be reliably and for any desired period of time arrested in the selected angular position, thereby avoiding the possibility of accidental turning and danger to an operator.
  • the invention is applicable to a comminutor having only a single rotor, it will be appreciated that it is particularly advantageous where a comminutor has two or more rotors, because a single unit 2 can serve two adjacent ones of the rotors.
  • the economy of constructing the arrangement according to the present invention is also significantly improved over what is known from the prior art.
  • wall means defining an interior chamber and having an outer side; rotor means mounted for rotation in said chamber and including a shaft having a shaft portion located at said outer side; a disk member fixedly mounted on said shaft portion and provided with a plurality of connecting portions which are spaced about the circumference of said shaft; a cylinder and piston unit having a first end and a second end; mounting means cooperating with said first end and pivotally mounting said unit on said wall means laterally spaced from said shaft and disk member; and connecting means for releasably connecting said second end of said unit with respective ones of said connecting portions when it is desired to change the angular position of said rotor means, so as to move the latter to a desired angular position in response to operation of said unit and prior to release of said connecting means from the respective connecting portion.
  • wall means defining an interior chamber; rotor means mounted for rotation in said chamber and comprising a rotary shaft; a cylinder and piston unit having a first end and a second end; mounting means cooperating with said first end and pivotally mounting said unit in said wall means laterally offset from said rotor means; and releasable connecting means for releasably connecting said second end of said unit with said rotor means, including a disk member fixed with said rotor means so as to rotate with said shaft and being provided with a plurality of angularly spaced openings, and a connector engageable with said second end and in a respective one of said openings so as to move said rotor means to a desired angular position in response to operation of said unit.
