Definitions
- both the heat treatment and the necessary Subsequent cooling under protective gas mostly nitrogen or hydrogen or a mixture of these gases.
- protective gas mostly nitrogen or hydrogen or a mixture of these gases.
- This is used to cool the annealing material Shielding gas extracted from the protective hood via a central radial fan passed for cooling via a heat exchanger before it is returned to the Protective hood flows.
- protective gas mostly nitrogen or hydrogen or a mixture of these gases.
- Flow channels are axially adjustable slides mounted in the pressure side Flow path of the radial fan can be advanced to the gas flow sucked in from the protective hood via the cooling chamber conduct that through an outer annular gap between the diffuser of the radial fan and the protective hood with the protective hood in flow connection stands.
- the flow channels are closed, so that the axially sucked inert gas over the impeller of the Radial blower passed through the diffuser in the circuit in the protective hood becomes.
- the slides are raised, which is the Deflection of the protective gas down to the cooling chamber results.
- the invention is therefore based on the object, a bell annealer of the type described at the beginning with simple constructive means such that advantageous protective gas cooling can be achieved without entering the Need to intervene sustainably in the construction of the glow socket.
- the invention solves this problem in that the protective hood Is mounted gas-tight over an annular flange that the heat exchanger below of the ring flange is that the flow channel from one of the outer circumference of the diffuser, concentric to the annular gap annular channel and that the deflecting device, as the outside of the diffuser, annular deflection slide is formed.
- the deflection device that cools Deflects shielding gas into the ring channel leading to the heat exchanger Exit side of the nozzle is assigned what advantageous flow conditions for the gas flow to be deflected, especially since the deflection slide encloses the guide apparatus continuously.
- the one from the outer circumference of the diffuser, designed as an annular channel also represents an advantageous prerequisite for a heat exchanger arrangement in the form of a ring surrounding the glow plug, which is a simple sealing of the protective hood via an annular flange enables without in to have to take special cooling measures in this area.
- the one below the heat exchanger arranged on the ring flange of the protective hood ensures the cooled shielding gas for appropriate cooling in this area.
- annular channel and the annular gap from each other through a cylindrical wall be separated, which is axially displaceably mounted and the annular Deflection slide carries. Because the cylindrical wall for adjusting the annular Deflection valve is used, otherwise necessary drive connections are omitted between the actuator and the deflection slide.
- the bell annealer has a glow socket 1, in which a radial fan 2 is mounted, the Impeller 3 is driven by a motor 4.
- the impeller 3 is from one Guide apparatus 5 enclosed, the guide vanes are designated 6.
- the annealing material 7 resting on the glow base 1, which is only indicated by broken lines is covered by a protective hood 8, which has an annular flange 9 is supported by a circumferential seal 10 for a gas-tight Completion of the protective hood 8 ensures.
- the glow socket 1 surrounded by a heat exchanger 11, which in on the outflow side an annular gap 12 between the protective hood 8 and the diffuser 5 opens.
- the heat exchanger 11 connects to a flow channel 13 which is designed as an annular channel 14 concentric with the annular gap 12.
- the Separation between the ring channel 14 and the annular gap 12 is carried out by a cylindrical wall 15 which is axially displaceable and with an actuator 16 is connected via lifting rods 17.
- the wall 15 carries one on the outside Guide device 5 connecting deflector in the form of a guide device 5 enclosing, annular deflection slide 18, which either the gas flow 1 in the protective hood 8 releases, as this by the Flow arrow 19 is indicated, or the gas flow according to FIG. 2 deflected into the ring channel 14. Due to the wedge-shaped cross section of the Deflection slide 18 can also be used in intermediate positions, what a temperature control of the protective gas in the protective hood 8th allowed.
- the deflection slide 18 advantageously fits into the gained Space, which brings a radially compact design with it.
- the deflection slide is used to cool the protective gas in the protective hood 8 18 from the lowered position shown in FIG. 1 in the 2 raised to a corresponding gas flow over to cool the annular channel 14 through the heat exchanger 11 and via the Feed the annular gap 12 back to the protective hood 8.
- the cooling of the protective gas in the area below the ring flange 9 brings a cooling of the Protective hood with the ring flange 9 in this area, what else necessary separate cooling measures are unnecessary.
