Definitions

  • the invention relates to a ventilation nozzle for liquids, in particular for aerating and atomizing beer wort and yeast with a liquid channel tapering in the flow direction, with a gas supply line for admixing a gas into the liquid channel and with an expansion space adjoining the taper in the flow direction.
  • Venturi nozzles Such a ventilation nozzle is known from practice.
  • so-called Venturi nozzles are used.
  • a gas stream is fed to the liquid flowing through the Venturi nozzle in such a way that the gas mixes with the liquid and the liquid is atomized in an expansion space adjoining the Venturi nozzle.
  • Such a ventilation nozzle is used e.g. in brewing technology for wort aeration and yeast aeration. If the wort flowing into the nozzle is mixed with air, a fine distribution of the air in the wort is achieved, which has a favorable influence on the flotation effect. With a very fine distribution of the air bubbles in the wort, a very even foam blanket formation is achieved during the flotation.
  • the nozzles used are usually constructed in one piece. Therefore, their interior is difficult to access for cleaning.
  • the invention has for its object to provide a ventilation nozzle for liquids, which is easy to clean inside, is simple and inexpensive to manufacture.
  • the liquid channel is formed from two telescopically pushed pipe sections in such a way that the strongly overlapping areas of the pipe sections delimit an annular channel, which is provided by circumferential recesses provided on the outside of one pipe section and on the inside of the other pipe section formed and sealed by seals provided on the mutually facing ends of the pipe sections to the liquid channel on the one hand and to the environment on the other hand, that the area separating the ring channel from the liquid channel is provided with gas passage openings, the gas supply line opening into the ring channel, and that the two pipe sections are connected to one another by means of radially outwardly projecting screw flanges and fastening screws distributed over their circumference, the screw flange of the annular channel na ch externally sealing pipe section is attached to the front end.
  • the liquid channel is formed from two pipe sections, the liquid channel can be broken down into two parts, as a result of which its inside is easily accessible and is therefore easy to clean. Since the overlapping areas delimit an annular channel, the inside of this annular channel is also easily accessible when the two pipe sections are taken apart. When the pipe sections are taken apart, the area of the gas passage openings is also accessible from both sides, so that the gas passage openings can also be easily cleaned.
  • the manufacture of the ventilation nozzle by the two-part construction of the liquid channel is particularly simple and therefore inexpensive.
  • the ring channel can be produced simply by turning off a part of the tube section which has the screw flange on the end, so that the recess running around the inside is formed.
  • the other part of the pipe section is turned off, creating the circumferential recess on the outside of this pipe section. In the latter, the gas passage openings can then be easily introduced through bores.
  • the assembly and disassembly of the two parts is particularly simple and reliable.
  • the ring channel is reliably and uniformly sealed over the circumference of the mutually facing end ends of the pipe sections.
  • the screw flange arranged on the end face has a circumferential groove on its surface facing the other screw flange, in which one of the seals for the annular channel is inserted.
  • a seal reliably seals the ring channel from the environment.
  • a commercially available O-ring can be used which, if its sealing effect wears off after a long period of use, can be easily replaced by a new sealing ring at any time.
  • the pipe section which has the screw flange on the end also has the other seal which seals the ring channel and is inserted into a circumferential groove.
  • the front end of the other tube section has a radially outward-pointing, shoulder-extending sealing flange which cooperates with the seal, the inside diameter of the two tube sections being the same size at this point.
  • the two assembled pipe sections form the liquid channel with a uniform, constant inner diameter at this point.
  • the circumferential groove has a T-shaped cross section, since a particularly effective sealing effect is achieved with a seal which has the same cross section.
  • the gas supply line is connected to the pipe section which has the screw flange on the end face and opens into the annular channel.
  • the gas can then be passed directly via the pipe section having the end screw flange into the ring channel, in which the gas is evenly distributed and fed to the liquid channel via the gas passage openings in the other pipe section becomes.
  • the end screw flange is advantageously attached as a separate component to the pipe section, preferably by welding. It forms part of the radial outer boundary of the ring channel. In this way, inexpensive prefabricated components can be used for the screw flange. Furthermore, the creation of the tube section having the end screw flange is simplified, since only a part of the circumferential recess on the inside, that is, a part of the outer boundary of the ring channel, has to be unscrewed. Furthermore, if the inside diameter of the screw flange on the face side corresponds to the inside diameter of the recess running around the inside of the pipe section, the outer boundary of the ring channel has a constant diameter along the entire length.
  • the screw flange of the other pipe section is pushed as a separate component radially onto the pipe section and fastened, preferably by welding. Because then it is also easy to manufacture the pipe section which does not have the screw flange arranged on the end face, since apart from the recess which delimits the annular channel inwards, it has a smooth surface. Furthermore, the separate components are commercially available and inexpensive. It is also possible for the screw flange of the other tube section to protrude axially beyond a wall axially delimiting the ring channel and likewise to form part of the radially outer delimitation of the ring channel. This will make the circumferential Recess, which must be formed on the inside of the pipe section having the front screw flange, is further shortened.
  • the two screw flanges can also be of identical design. This has the advantage that only one type of screw flange has to be present in the manufacture of the ventilation nozzle. These screw flanges can then be attached to both pipe sections simply by welding.
  • the screw flanges can be arranged approximately in the middle of the ventilation nozzle. This simplifies the storage of the individual pipe sections, since they are approximately the same length. Furthermore, a favorable division of the liquid channel is achieved in the disassembled state, since none of the pipe sections is unnecessarily long. This means that both liquid channels are easily accessible for cleaning. Also, the overlapping area of the two pipe sections is small in this arrangement, so that the ventilation nozzle can be assembled and disassembled easily without the two parts easily tilting or bumping against one another and thus being damaged.
  • the single figure shows a partially longitudinally cut ventilation nozzle according to the invention.
  • the ventilation nozzle according to the invention has a liquid channel 1, which tapers in the direction of flow 2.
  • An expansion space 3 adjoins the liquid channel 1 in the flow direction 2.
  • the Liquid channel 1 is formed from two pipe sections, one of the pipe sections 4 having a screw flange 5 on the end face, which is screwed to a screw flange 7 attached to the other pipe section 6 with fastening screws 8 distributed over its circumference.
  • the two pipe sections 4, 6 are telescoped. In their overlapping area, the two tube sections 4, 6 delimit an annular channel 9.
  • the annular channel is formed by a recess 10 running around on the outside of the tube section 6.
  • the outer boundary is partially formed by a recess 11 on the inside of the pipe section 4.
  • Another part of the outer boundary of the ring channel 9 is formed by the inner diameter of the screw flange 5 on the end face.
  • the inner diameter of the screw flange 5 corresponds to the inner diameter of the recess 11, so that the outer boundary of the annular chamber 9 has a constant diameter.
  • Another small part of the outer boundary of the annular chamber 9 is formed by the inner diameter of the screw flange 7, which is designed to match the inner diameter of the screw flange 5.
  • the screw flanges 5 and 7 are the same components.
  • the screw flange 5 is attached to the pipe section 4 by welding.
  • the screw flange 7 is axially attached to the jacket of the pipe section 6 by welding.
  • the screw flanges 5, 7 are arranged approximately in the middle of the ventilation nozzle.
  • the screw flange 5 arranged at the end has a circumferential groove 12 with a T-shaped cross section on its surface facing the flange 7, into which a sealing ring is inserted.
  • the ring channel 9 is sealed to the outside by this seal 12.
  • the pipe section 4 has a radially inwardly projecting shoulder 13 which is axially spaced from its end face and which axially delimits the annular channel 9.
  • the front end of the other tube section 6 has a radially outward-pointing sealing flange 14 which extends into the shoulder 13.
  • the inside diameter of the two pipe sections 4, 6 is the same size at this point.
  • An axially open, circumferential groove 15 with a T-shaped cross section is formed in the shoulder 13.
  • a sealing ring is arranged in the groove 15 and seals the ring channel 9 against the liquid channel 1.
  • a gas supply line 16 is formed in the boundary of the annular channel 9, which is delimited by the pipe section 4 having the end screw flange 5.
  • Gas passage openings 17 are formed in the boundary of the annular chamber 9, which is formed by the other tube section 6. The gas is conducted into the annular chamber 9 via the gas supply line in the pipe section 4, is distributed there and reaches the liquid channel 1 via the gas passage openings 17.
  • the two pipe sections 4, 6 are put together, sealing rings being inserted into the grooves 12 and 15 provided in the pipe section 4.
  • the screw flanges 5, 7 are screwed together by means of the fastening screws 8 arranged along their circumference.
  • the aeration nozzle is installed in the device with which the wort or beer yeast is aerated or atomized.
  • the wort is supplied to the liquid channel so that it flows through the liquid channel 1 in the direction of flow 2.
  • a gas is in via the gas supply line 16 the ring channel 9 passed.
  • the pressure of the gas is selected so that the gas is evenly distributed in the annular channel 9 and reaches the liquid channel 1 via the gas passage openings 17.
  • the liquid is enveloped by the gas streams like a net.
  • the gas / liquid mixture then continues to flow in the direction of flow 2 and reaches the tapered end of the liquid channel 1, in which the gas mixes with the liquid.
  • the gas / liquid mixture reaches the expansion space 3 via a pressure drop. Because of this pressure drop, the wort / air mixture is expanded. This creates an even bubble formation in the wort. This effect influences the flotation in such a way that a very uniform foam blanket formation is achieved.
  • the aeration nozzle can be removed again from the wort aeration device.
  • the aeration nozzle If the aeration nozzle is to be cleaned, it can be disassembled for this purpose and, after cleaning, reassembled and installed in the wort aeration device. Likewise, if one of the pipe sections is damaged or shows signs of wear, the ventilation nozzle can be disassembled, one of the pipe sections can be replaced and the ventilation nozzle can be reassembled. If the aeration nozzle is installed again in the wort aeration device, the aeration process can begin again.
