Definitions

  • the invention relates to a device for closing an emptying opening arranged in the bottom of a container, preferably a turntable of a processing machine, with a closure lid arranged on a rotary shaft via a support arm and entering the emptying opening, the rotary shaft and support arm being provided outside the container next to the bottom thereof.
  • Sealing devices of the type mentioned above, in particular for mixing machines with a rotating plate, are known in principle.
  • the closure cover is always rigidly connected to the support arm and the rotary shaft. In such an arrangement, the closure cover then necessarily executes a circular movement around the rotary shaft.
  • the closure lid can only be retracted into the emptying opening of the container bottom if there is considerable play between the outside diameter of the closure lid and the inside diameter of the emptying opening, so that the horizontal movement component of the circular movement is caused by the difference in diameter resulting gap can be intercepted. Due to the gap there is, however, considerable leakage in this embodiment, so that no liquid or fine-grained substances can be treated in such a sealed container.
  • a flap closure on mixing machines is also known, in which the circular movement during entry into the container bottom is converted into a linear movement by parallel guidance.
  • This construction is disadvantageous in terms of machine technology, requires a large overall height of the mixing machine and requires extensive maintenance and care work, especially since this mechanism with its pivot bearings moves in a space through which the material flowing out of the mixing container flows.
  • the object of the invention is therefore to provide a closing device of the type mentioned, with which despite reliable construction and favorable installation conditions, a reliable closure with considerably better tightness is provided.
  • closure lid and the support arm, between which an elastic member is connected are rigidly connected to one another via a hinge having tabs and rotatably connected to one another about a tilt axis, and in that the tilt axis is formed by a tilt bearing arranged in the tabs .
  • the first part of the closing movement is still carried out by means of a normal circular movement, in which the support arm moves on an arc through the driven rotary shaft.
  • the elastic member engages, allowing the closure cover to be deflected from the circular movement, so that it slides perpendicularly to the closure cover into the discharge opening, while the support arm holding the cover the circular movement ends.
  • the elastic member thus compensates for the difference in the direction of movement between the centering ring or the inner edge of the emptying opening on the one hand and the outer edge of the closure cover on the other.
  • the structure of the rigid support arm which is fixed to the rotary shaft and is known from the prior art, can be maintained because the elastic member is seen in function only behind the support arm, ie between the latter and the closure cover.
  • the elastic member is a rubber or plastic part covered with metal plates, which is arranged between the closure cover and the tilting bearing, the tilting axis of which runs parallel to the axis of the rotary shaft and which has a radial spherical plain bearing.
  • Such an elastic member is sometimes referred to as "vibrating metal” and has the shape of a cube or cuboid, which has a compressible elastic plastic or rubber body inside, which is reinforced on at least two opposite surfaces with the metal plates mentioned, for. B. with a laminated core or a thicker iron sheet.
  • the metal reinforcement on the two outer sides results in good mechanical engagement options which are also used according to the invention in this elastic member.
  • the tilt bearing allows movement of one metal plate of the elastic member with respect to the other, although of course both plates are firmly connected to each other with the exception of the described tilting possibility, e.g. B. on landings, as will be described.
  • a spring or a hydraulic or pneumatic bellows could also be used as the elastic link.
  • the closure cover is practically connected to the support arm via a hinge which, as mentioned above, allows the tilting movement in the required direction.
  • tilting in only one direction is permitted.
  • the tilting bearing is fastened to the support arm and has a bearing plate with threaded bores for receiving at least one pressure screw and one adjusting screw.
  • Said bearing plate connects the two radial spherical bearings and is in the form of at least one web or a plate on the side of the closure cover which is opposite in relation to the elastic member.
  • the pressure screw is pressed against the side of the elastic member facing away from the sealing cap, which has a blind hole for the passage of the adjusting screw on the metal plate attached to the sealing cap or a pressure plate of the elastic member is held down.
  • the prestressing on the elastic member can thus be set in a very simple manner. For example, pressing the pressure screw down compresses the elastic body arranged between the metal plates, so that the elastic member acts harder. The opposite is of course achieved when the pressure screw is unscrewed.
  • stop screws can also be provided, or the adjusting screws can take over their function, namely. Determine end positions of the elastic member so that occurring pressures, for. B. with material jams during the closing process, do not overload the elastic member.
  • closure cover in the middle region is held in a rotary bearing Pivot and has a sealing ring on the outside.
  • the arrangement of the sealing ring means that the annular gap, which can be adjusted extremely narrowly by the measures according to the invention, can even be sealed in a liquid-tight manner, by means of the pivot bearing and the pivot even for a rotating cover.
  • This closing device is therefore also of particular interest for compulsory mixers with a rotating container.
  • the tank bottom 1 shown in FIGS. 1 and 2 is covered with armor 2 on its surface. This results in a not inconsiderable material thickness in the emptying opening 3, so that the closure cover 4, the surface of which must be flush with the surface of the armor 2 of the container base 1, must perform a not inconsiderable component of movement transversely to the container base 1, after which the circular movement described above occurs along the arc lines shown in Fig. 2.
  • the embodiment shown here is a compulsory mixer, the turntable axis of which is not perpendicular but an angle of z. B. is tilted 30 ° from the vertical. Therefore, the container bottom 1 is shown obliquely in FIGS. 1 and 2.
  • the container designed as a turntable extends upwards, so that the arrangement shown here is outside the container and below it.
  • the support arm 6 On the driven on the machine frame, not shown, and rotatably mounted rotary shaft 5, the support arm 6 is attached, which carries the closure cover 4 at its free end via the hinge 7 (Fig. 3), the elastic member 8 and the tilt bearing 9.
  • the closure cover 4 and the support arm 6 are rigidly connected to the tilt bearing 9 via the hinge 7.
  • the tilting is made possible in that the tilting bearing 9 has spherical bearings 12 on the outside at the opposite ends of a bearing plate, which are only shown in FIG. 3. It can thus be seen that, according to FIG. 3, the closure cover 4 cannot be tilted in the paper plane, but can be tilted perpendicular to it, namely about the tilt axis 10, which lies parallel to the axis of the rotary shaft 5.
  • 1 shows the operating position, in which the tilting bearing 9 is tilted while compressing the left half of the rubber or plastic part.
  • 2 shows the relieved state.
  • the bearing plate 11 of the tilt bearing 9 has threaded holes 13 and 14, which can only be seen in the sectional views of FIGS. 1 and 2, the pressure screw 15 against the outer metal plate 16 and the adjusting screw 17 (both secured by lock nuts 18) against the inner metal plate 19 of the elastic member 8 is screwed, held pressed and thereby pressed against the pressure plate 24. It can also be seen that the middle rubber part of the elastic member 8 has a bore 20 which is extended to be flush with the bore 21 of the outer metal plate 16 for receiving the adjusting screw 17. This results in a blind bore 20, 21 in the elastic member 8.
  • a strip 22 is screwed to the bearing plate 11 of the tilting bearing 9 for holding and guiding the elastic member 8.
  • the rubber ring 26 fastened by means of the pressure ring 23 on the outer circumference of the closure cover 4 can be clearly seen from FIG. 3.
  • closure cover which is forcibly preferably driven at a variable speed.
  • the drive is attached to the cover so that it follows the deflection movement.
  • the prestressing of the elastic member 8 is first set by tightening the pressure screw 15. Then, by screwing in the adjusting screw 17, such a position of the closure cover 4 is adjusted that when the position shown in solid lines in FIG. H. during the transition from the linear to the rotary movement, the free outer end of the adjusting screw 17 just lies against the inner metal plate 19, as shown in FIG. 2. This ensures that the surface of the cap 4 is really parallel to the surface of the bottom 1 of the container. With 25, the bearing bush for the cover 4 is designated.
