Abstract
The present invention relates to a shiftable positioner of a rotary blowing instrument for the dehydrogenation of molten aluminum, which belongs to the field of the purification treatment of metal. In the present invention, a fixed slide plate is arranged in the position of a machine base where the bracket of a rotary nozzle passes when the rotary nozzle descends, fixed on the machine base via a screw or in the mode of welding, and provided with two chutes via which a travel switch is arranged on the slide plate, so that the travel switch can be fixed on the slide plate, and can reciprocate when needed. The present invention with the advantage of reasonable structure not only effectively prevents the rotary nozzle from excessively descending so as to avoid damage to equipment but also smartly changes the extreme lower descending position of the rotary nozzle, and is suitable for molten aluminum processing furnaces (or chutes) with different dimensions so as to obviously enhance the safety and the adaptability of rotary blowing instruments for the dehydrogenation of molten aluminum.
Description
Technical field
What the present invention relates to is winding-up instrument locating device during a kind of metal purification is handled, and particularly a kind of removing hydrogen from aluminum melt rotary blowing instrument baffle plate belongs to the metal purification process field.
Background technology
The rotary blowing instrument that is used for removing hydrogen from aluminum melt, when molten aluminium being carried out the dehydrogenation processing, by a rotating rotor and shower nozzle rare gas element (as nitrogen, argon) is imported in the molten aluminium, the hydrogen that is dissolved in the molten aluminium is moved to from melt in the rare gas element bubble owing to partial pressure difference, and swim to bath surface, thereby reach the purpose of dehydrogenation with bubble.In order to obtain high efficiency dehydrogenation effect, not only to make contact area, the duration of contact of bubble that rotary nozzle imports and aluminium liquid big as far as possible, and require to make the bubble disperse be distributed in equably in the whole aluminium liquid by the eddy current of rotary nozzle and aluminium liquid self.Therefore, for the aluminium liquid pack processing (or chute) of different size, the degree of depth that rotary nozzle stretches into aluminium liquid has specific requirement.In addition, stretch in the process excessively, cause rotary nozzle, aluminium pack processing (or chute) to be damaged in order to prevent that rotary nozzle from stretching into.Be necessary a travel switch to be installed, so that the minimum lowering position of controls revolution shower nozzle at the support place of rotary nozzle.Find that by literature search " products catalogue specification sheets " CALGAS2000 air-removal equipment that P8-9 mentioned that U.S. Pyrotec high-temperature material company limited is provided is exactly at the support place of rotary nozzle a contact travel switch to be installed.Can prevent effectively that like this rotary nozzle from reducing excessively.But because travel switch is fixed on a position, therefore, at the different positions that promptly requires the design runlength switch for the aluminium liquid pack processing (or chute) of different size, be unfavorable for the batch process of equipment like this, and also be the factor of an inconvenience for the user, when the size of change aluminium liquid pack processing (or chute), just must change rotary blowing equipment.
Summary of the invention
The present invention is directed to the deficiencies in the prior art and defective, a kind of Aluminium Melting Body Degassing Fydrogen Rotatary Spraying Device Portable Locating Device rational in infrastructure is provided, make it can prevent effectively that rotary nozzle from descending excessively, the extreme lower position that can descend to rotary nozzle easily again changes simultaneously, thereby the security of equipment, adaptability are significantly improved.
The present invention is achieved through the following technical solutions, and the support position of the support process of rotary nozzle was provided with a fixed slide plate when the present invention descended at rotary nozzle, and this slide plate is fixed on the support by the form of screw or welding.Two chutes are set on slide plate, and travel switch is installed on the slide plate by these two chutes, utilizes four Luo bolts and mother Luo to be fixed on travel switch on the slide plate like this.When aluminium pack processing (or chute) size change or experimentize etc. needs to change the minimum lowering position of rotary nozzle, can unclamp the Luo bolt, make travel switch in the chute length range, freely to move up and down.Realized so promptly that in the equipment use travel switch can be lived in a certain stationkeeping, plays the safeguard protection effect; And when the minimum lowering position of needs change rotary nozzle, can on slide plate, slide up and down by travel switch again and realize, improved the adaptability of equipment.
Pass through on the planar side when slide plate is installed in the cantilever oscilaltion of supporting rotary nozzle, and near cantilever the Plane Installation of process.Cantilever was residing probably highly definite when the particular location that slide plate is installed can pass through the rotary nozzle extreme lower position.The length of slide plate can determine that the width of slide plate is determined by the width of travel switch by the rotary nozzle extreme lower position regulation range that designing institute needs.Slide plate can be installed in by the mode of screw or welding on the support, and after travel switch was contained on the slide plate like this, in cantilever decline process, the stroke contact lever that stretches out by the travel switch that is installed on the slide plate can stop the continuation of cantilever to descend.
Two chutes on the slide plate are a bit larger tham mother's Luo of fixed journey system switch width at the width by equipment support one side, this one side that makes mother Luo can put into chute also can slide up and down freely, and be a bit larger tham the diameter of the Luo bolt of fixed journey system switch at width by two chutes of the one side of travel switch, make the Luo bolt in chute, to slide freely.
When travel switch was installed, the Luo bolt passed Luo hole on the travel switch and chute and screws by mother Luo who is embedded in the chute inboard, thereby reaches the fixed journey system switching purposes.In addition, unclamp being connected of Luo bolt and mother Luo, can make travel switch on slide plate, to move up and down.
When the cantilever that hangs rotary nozzle dropped to the height location of travel switch, cantilever just contacted with the contact lever of travel switch, and at this moment travel switch produces the Controlling System of a signal to the rotary blowing instrument, makes the decline of cantilever be prevented from.If will change the minimum lowering position of rotary nozzle, promptly change the position of travel switch, only need that pine is a bit a little location Luo bolt and location mother Luo, just can drive the Luo bolt to travel switch and mother Luo moves up and down together, when moving to the desired position, again Luo bolt and mother Luo are tightened again, so just travel switch is fixed on the desired position and has located.
The present invention has substantive distinguishing features and marked improvement, the present invention is rational in infrastructure, both prevented the structure deteriorate that rotary nozzle descends and excessively causes effectively, can also change simultaneously the extreme lower position that rotary nozzle descends neatly, the aluminium liquid that adapts to different size is handled stove (or chute), thereby has improved the security and the adaptability of removing hydrogen from aluminum melt rotary blowing instrument significantly.
