Definitions

  • the invention relates to a double jacket storage for the preparation and storage of hot industrial water according to the preamble of claim 1.
  • Double jacket stores of this type are generally known and in use, so that no special printed evidence is required in this regard.
  • the connection of the supply and return connections leading the heating medium to the outer jacket is problematic insofar as the ring-shaped outer jacket end plate adjoining the outer jacket upwards has a small radial width in consideration of the most compact dimensions of the entire tank with the smallest possible heating medium volume between the storage tank and the outer jacket the convenient connection of the flow and return connections there does not allow.
  • These were therefore attached to corresponding lateral openings on the outer jacket with corresponding 90 ° pipe elbows, the elbows also having to be kept large enough to be able to lay flawless weld seams. This therefore leads to a correspondingly large space requirement on the side of the accumulator.
  • the annular outer jacket end plate must remain accessible for automatic mechanical welding.
  • the invention is therefore based on the object to design and improve a double jacket storage of the type mentioned with regard to the connection of the supply and return connections for the heating medium in such a way that after mechanical welding of the outer jacket end plate is carried out with minimal lateral space stress on the memory and axially parallel outlet on the outer jacket can be.
  • the connecting pipe pieces are first simply welded on the bottom side next to the openings on the outer jacket, specifically with the pipe pieces aligned axially parallel to the storage axis, ie the small flanges of the pipe pieces are perpendicular to the outer jacket, advantageously their edge part to be welded is adapted to the curvature of the outer jacket.
  • the transition pieces adapted to the gusset shape and advantageously by deep drawing or pressing are now used, which thus cover the openings in the outer jacket and which are now welded from the outside along their connecting edges to the flanges and to the outer jacket .
  • the manufacture of the pipe and transition pieces is very simple, since, as mentioned, the transition pieces can be easily deep-drawn from correspondingly small sheet metal blanks, because open structures are to be created on both sides without interruption.
  • the small flanges at the pipe ends are advantageously attached by roller cranking and cut secantially at any point in order to create a correspondingly long connecting wheel to the outer jacket, which is expediently slightly arcuate, corresponding to the curvature of the outer jacket.
  • a similar connection which takes up just as little space, can also be achieved in accordance with claim 1 in conjunction with claim 6 by cutting out a correspondingly long part of the pipe end on one side in the longitudinal direction or deforming it flatly and thus placing the pipe laterally on the outer jacket, the then still open end of the tube must be closed in a suitable manner, which will be explained in more detail.
  • the return flow opening is arranged on the bottom of the outer jacket, which is remote from the connection, and from there a return line is led outside the outer jacket to the connection side of the storage tank, it is not necessary to form the actual return connection in the aforementioned manner, but (this will also be explained in more detail), this will be done the actual return connection forming pipe section deformed with its connection end so that it can be inserted into or onto the upper end of the return line and welded to it.
  • the supply and return connections 6, 7 are made of transition pieces 9 which are open on two sides without interruption and are formed from connecting pipe pieces 10, the transition pieces 9 having an open side 11 on the peripheral edge region 13 of openings 14 in the Outer jacket 2 are placed and the other open side 12 oriented at right angles thereto is closed with a connecting flange 15 of the respective connecting pipe piece 10.
  • FIG. 3 which clearly illustrates this requirement.
  • FIG. 1 shows how close the supply and return connections 6, 7 can be arranged on the outer jacket 2, that is, the supply and return connections 6, 7 are longitudinal axes LA parallel to the container longitudinal axis BA with a distance D to the wall W des Outer jacket 2 arranged, which is only slightly larger than half the diameter of the outlet openings of the connections 6, 7.
  • Fig. 1 shows how the annular outer jacket end plate 8 is usually shaped and inserted and welded between the bottom 5 and the outer jacket 2, that is, there is no smoothly cylindrically tapering peripheral edge 17. Such a cylindrically smoothly running edge 17 can, however, as FIG.
  • the supply and return connections 6, 7 are formed from tubes 3 ', 4', the connection ends of which are on one side form-adapted to the outer jacket 2 and provided with an overflow opening 14 ', applied to the outer jacket 2 via its overflow opening 14 and welded all around to the outer jacket 2.
  • the tubes 3 ', 4' are provided with a lateral cutout 18 at their connecting ends, and the wall tab 19 of the connecting end is formed into a closure cap 20.
  • a shape can be easily produced with correspondingly adapted press tools. Without having to make a cutout 18 at the end of the tube, this can also be deformed in the sense of FIGS. 5, 7, that is to say the wall of the tubes 3 ', 4' at one end thereof is one-sided to a connecting surface 21 and the other Part of the wall is deformed to form a closure cap 20, the overflow opening 14 ′ having to be provided in the connection surface 21 here. It does not matter that a gap 20 'with the shape shown is initially open, since the whole thing is then welded to the outer jacket 2 along the dash-dotted line.
  • the embodiment of the memory according to FIGS. 6, 8 shows a different design of the return RL, ie the flow connection 6 does not require any further explanation here, since it can be designed in one way or another as described above (FIGS. 1, 4 or 5).
  • the return RL it is attached to an opening 22 of the outer jacket base 23 and is guided as a return line 24 on the outside of the outer jacket 2 to the connection side of the accumulator, in the end 25 of which the correspondingly shaped return port 7 is inserted and welded.
  • the double jacket storage unit according to FIG. 6 is, moreover, one for a horizontal one Arrangement that is shown in vertical position only for reasons of space.
