Definitions

  • the invention has for its object to provide means for feeding paper pulp and the like to the sieve of a paper making machine, cell de-watering machine,.and the like.
  • the discharge velocity of the stock is approximately equal to the velocity of the sieve.
  • the height of the stock in the stock casing varies with the change in the working velocity and, in consequence, with the sieve velocity.
  • the distance between the upper and lower lips of the outlet nozzle is varied with changes in the thickness of the stock and in the viscosity thereof.
  • Figure 3 is a side view of a structure'adapted to a low working speed, v s
  • Figure 4 is a side view of a structure having a controllable breast roll and a controllable table, adapted to a high working speed
  • Figure 5 isa similar view of a structure having a controllable breast roll and a controllable table, adapted to a low working speed.
  • Figures 6, '7 and 8 show views of the adjusting means; and v Figure 9 is'a side view of means for adjusting 1 the roll.
  • the stock therein collected passes through the distributing roll B, as shown in Figure 1, or between plates 0, as shown in Figure 3, into the nozzle D.
  • This nozzle D consists of a fixed underlip d and movable upperlip d, which is'adjustable .so as to increase or decreasethe nozzle discharge opening.
  • the stock discharged by the nozzle passes upon the sieve E, which passes around thegbreast roll F, These parts are known.
  • the improvement consists in roviding means to control the position of the reast roll F in respect to the flxedstock inlet casing A.
  • the invention overcomes these objections, and consists in the regulation of breast roll alone or in connection with the table or table rolls, that is, the front'part of the table, in horizontal or vertical or both directions; it is possible to control the direction of the stock stream, and also the position of the same upon the sieve, in accordance with demands of the operation of the plant.
  • FIG. 1 is a sideview of a structure embodying the invention, having a controllable breast roll adapted to a stock flow of high working speed, I
  • Figure 2 is a view taken at right angles to that of Figure 1, of the same structure as shown in by the adjustable device J, which permits the breast roll F'to be raised or lowered whereby the height in vertical direction is controlled.
  • the breast roll may also be controlled in a horizontal-direction toward and away from the casing A, and this is accomplished by the sliding guide device K arranged in the baseL.
  • the first table roll G is made'larger than the other table rolls and is given a large diameter.
  • the large table roll G is also controllable in respect to vertical and horizontal positions, by suitable means shown in Fig. 9.
  • a roll H for tensioning the sieve E is also provided; and the'table r011 G'and the tension roll H serve for adjusting and supporting the sieve. These rolls also act in a compensatory manner, during the regulation of the breast roll.
  • the table F can also, be controlled by the table, rollbar G the rolls F and the bar G consti-f tuting-the known table, that is, in cooperation with the control of the breast roll.
  • the table F By the operation of the adjusting device J, the table F may be vertically raised or lowered, and by the operation of the slide in the guide K in the base L, the table F may be horizontally controlled toward or away from the casing A.
  • the movement of the breast roll and the table F in vertical direction can be achieved by the worm spindle which passes through the same, or by means of a hand actuation of the device J.
  • a displacement of the standard M it here is possible to bring about a movement from the breast roll F, in respect to the discharge openin'g of the nozzle D.
  • the front part of the table is controlled as described.
  • Figs. 6, '1, and a. show the adjusting device for the design as shown in Figs. 1 to 5.
  • the crosswise worm shaft N is shown.
  • Worm shaft N actuates through a worm gear O, adjusting device J; 1
  • adjustment is made by means of a crossshaft P.
  • This cross shaft P drives over a gear set Q, adjusting spindle J.
  • Figure 9 shows the possibility of adjusting the roll G horizontally and vertically.
  • the slide carriage In a dovetailed guide S of bearing support R the slide carriage is operated which at its upper end, in
  • a clamping device I carries roll-G.
  • the adjustment of the slide carriage T in horizontal direction, is effected by a hand wheel.
  • This hand wheel turns a spindle V along which moves a square nut held between the walls of the slide carriage which causes the latter to move in horizontal direction.
  • the vertical movement of roll G is effected by disengaging clamping device U.
  • the invention is, of course, not alone applicable to paper making machines or the like, but
  • a support on the breast roll for supporting one end of the table bar, the change in inclination of which changes the inclination of the sieve, whereby the table bar will adjust the sieve in.
