Definitions

  • MIXING CONTAINER FOR AUTOMATICALLY MIXING OF HYDRAULICALLY HARDENABLE BINDING MEANS Filed March 9, 1966 IN V EN TOR.
  • the present invention relates to a mixing container for automatically mixing hydraulically hardenable binding means, such as cement with water, at the bottom of which mixing container there is arranged an agitator movable from the outside.
  • the binding material withdrawn from a storage container is through a pressuretight closable opening introduced into the mixing container while feeding lines for water and compressed air lead into said mixing container.
  • a discharge opening at the bottom of the mixing container and a connecting line leading to a main mixing drum the binding means-water mixture is by compressed air conveyed from said mixing container to said main mixing drum.
  • the charging opening of the mixing container is adapted to be closed by a spherical cover engaging the mixing container from the inside and supported by a tiltable lever located outside the mixing container and laterally of the central axis thereof.
  • the inlet opening is arranged in the central portion of the hood closing the mixing container at the top, and comprises an upwardly directed funnel which receives the feeding means for the binding means.
  • the inlet opening does not have to be as large as it would be desirable in order to introduce the cement into the mixing container in a minimum of time because at least a path having the length of the diameter of the inlet opening is required for tilting the spherical cover toward the side.
  • the mixing container hood must have a diameter at least equalling three times the diameter of the inlet opening.
  • the spherical cover which covers the inlet opening will during the introduction of the cement still extend into the inlet opening and will thus interfere not only with the proper charging of the cement but there will also be encountered sealing difliculties because the cement dropping onto the protruding portion of the cover will harden together with the spray water so that the cover can no longer properly tightly engage the inside of the mixing container.
  • the provision of feeding lines on the hood closing the mixing container will at least be made more difiicult or may even be made impossible if automatic closing, control and measuring devices are provided on the feeding lines.
  • a further object of this invention consists in the provision of a mixing container as set forth above, which will permit making the inlet opening sufficiently wide to allow the introduction of cement into the mixing container in a minimum of time while avoiding the development of dust.
  • FIG. 1 diagrammatically illustrates a cross section through a hood or cover for a mixing container according to the invention with an inlet connection mounted thereon.
  • FIG. 2 illustrates that portion of FIG. 1 on an enlarged scale which is encircled in FIG. 1 by the dot-dash circle C.
  • FIG. 3 illustrates a section through a modified closure arrangement according to the invention.
  • the present invention is characterized primarily in that the inlet opening into the mixing container is eccentrically arranged therewith and is adapted to be closed by a cover at the top of the container.
  • the cover itself may consist of elastic material, such as rubber of sufiicient strength but with a sufficient soft surface, or it may be lined with elastic material, such as rubber which is adapted sealingly to engage a seat of metal or synthetic material adapted to repel the binding means.
  • the inlet connection connecting the inlet opening with the feeding line for the binding means has at its free end face a tubular member which is evenly spaced from the inner wall of the inlet connection and is connected thereto in a dust-proof manner.
  • the tubular member protrudes beyond the inlet connection while the other end is located within the inlet opening and is surrounded by an annular water line with downwardly extending nozzles.
  • the mixing container generally designated 11 as illustrated in the drawing is closed toward the top by a hood or cover 14.
  • Eccentrically arranged with regard to the container cover 14 there is provided an inlet opening 31 around which there is mounted a tubular inlet connection 32.
  • the inlet opening 31 may be closed by a cover 12 adapted from the inside to engage the mixing container 11.
  • Cover 12 may be provided with a layer of elastic material 44 whereby a particularly satisfactory seal will be obtained.
  • the seat 43 of the spherical cover 14 consists of metal, such as bronze, or synthetic material, such as rubber, which will repel or reject the binding means.
  • This plate will, when freeing the inlet opening, by means of the spherical cover rest on the opening of the inlet connection in such a way that the unavoidably forming dust will not be able during the charging of the binding means into the mixing container, to escape outwardly and thereby to form crusts on the container.
  • the plate may be shaped in conformity with the shape of said opening so as to be able during the tilting movement of the lever to enter said opening. In this instance, the plate will be flush With the inner wall of the inlet connection and will not interfere with the charging of the binding means. That side of the crank which faces the spherical cover 12 may also be resilient in order to assure that cover 12 will, when closing the inlet opening, lightly engage the seat below the inlet opening so that losses in pressure during the feeding of mixing material by compressed air will be avoided.
  • a rubber seal may be provided at the bottom edge of the inlet connection which preferably extends into the cover of the mixing container.
  • a rubber ringO-ringwith suitable preferably round cross section is pressed into a groove.
  • the rubber seal saves a machining of the top side of the spherical cover 12 because rough parts or deposits will be compensated for by the elasticity of the rubber seal.
  • An advantageously dovetail-shaped groove prevents a detachment of the rubber ring.
  • the groove is provided with unevenly long legs while that leg which faces the inlet opening is the shorter one so that the spherical cover will snugly engage the seal but will be unable to compress the seal beyond an admissible extent because, while still sealing properly, it will abut against the inside of the mixing container at the end face of the inlet connection.
  • cover 12 is by means of a crank 33, 34 connected to a lever 13.
  • Crank section 33 is adapted to pull the spherical cover 12 resiliently against a rubber seal 35 which is inserted in a dovetail-shaped groove 36.
  • Groove 36 has unevenly long legs 36a and 36b which approximately correspond to the curvature of cover 12 to be pressed against the container.
  • That side of crank 34 which faces the pivot bearing 9 of lever 13 forms a circular section the center point of which is located on the axis of the pivot bearing 9.
  • This section of crank 34 passes through an opening 37 in the charging passage 32.
  • a plate 38 arranged at the end of crank section 34 will in the open position of cover 12 enter the opening 37 as shown in dash lines in FIG. 1 and will thus close the said opening 37 toward the outside.
  • a tubular member 39 Coaxially arranged with regard to the inlet connection 32 there is a tubular member 39 which has that portion 39a thereof which protrudes beyond the inlet connection 32 arranged for receiving elastic connecting means, such as hoses, while the portion 39b of said tubular member 39 extends into the inlet connection 32 and shields a water line 40 against binding means dropping into the container.
  • Water line 49 has downwardly directed nozzle means or openings 41 which, when introducing water into the mixing container, will spray cover 12 and clean the same from any cement or cement water residue which might deposit thereon.
  • the arrangement of the charging opening eccentrically with regard to the mixing container makes it possible that the spherical cover, which is adapted to close the charging opening, can be tilted far enough inside said mixing container to fully free a sufficiently large inlet opening. Moreover, this arrangement also makes possible the mounting of a plurality of units on the cover because the inlet opening, even with a funnel or inlet connection mounted thereon, leaves still sufiicient space for mounting additional feeding lines or a drive extending from the top into the mixing container.
  • the binding means which now drops into the mixing container eccentrically with regard thereto is immediately caught by the strong flow forming along the walls of the mixing container and is conveyed to the agitator. In this way, also the formation of cement nests will be prevented.
  • a cover according to the present invention may be used e.g. in connection with an apparatus as disclosed in my copending application entitled Method of and Apparatus for Mixing Hydraulically Hardenable Binding Material and Water and filed of even date herewith. It may also be added that arm 33 of the crank 33, 34 may be slightly resilient.
  • cover 12 is continuously urged sealingly to engage seat 35 at the inner end of said tubular member 32. This may be effected for instance by a spring. The movement of cover 12 away from its seat 35 may be elfected manually by correspondingly tilting arm 13 in counter-clockwise direction.
  • a mixing apparatus including a container for automatically mixing hydraulically hardenable binding material, especially cement, with water: first cover means forming the top portion of said container, said first cover means having an opening therethrough eccentrically arranged in said first cover means, main tubular means arranged in said opening and connected to said first cover means while outwardly protruding therefrom, the inner end of said main tubular means forming a discharge opening leading into the interior of said container and being adapted selectively to be closed and opened, said tubular means being adapted to receive binding material and discharge the same into said container, that side portion of said tubular means which is adjacent the central portion of said first cover means having a passage therethrough, second cover means arranged within said container and being continuously urged into closing engagement with said inner end of said main tubular means for closing said discharge opening, said second cover means being operable to disengage said main tubular means and to move into a maximum opening position to fully free said opening, lever means pivotally supported by said main cover means and including a cranked portion having first arm means extending from the outside of said container
  • said second cover means has a spherical shape arched toward the interior of said main tubular means, and in which the inner end of said main tubular means is provided with a dovetailed groove, and O-ring means confined in said groove and adapted sealingly to be engaged by the marginal area of said second cover means.
