Description
Technical field
The utility model relates to vacuum melting furnace, and especially a kind of vacuum melting furnace is used air draft mechanism.
Background technology
At present, existing vacuum smelting fast solidification stove is under vacuum or protective atmosphere, through eddy-current heating metal or alloy is melted, and through water cooled rolls metal or alloy is cooled off fast then, forms specific crystal or non crystalline structure material.In order to shorten the cool time that falls into the aqueous cold plate furnace charge from water cooled rolls, must accomplish quick continual heat exchanging process through blower fan.But original blower fan is more because of the structure problem fault, has a strong impact on production.Because the cooling blower maintainability directly has influence on the cooling velocity and the product quality of getting rid of sheet.Original blower fan causes to produce and pauses because of structure problem often damages because of bearing running hot in the course of the work.Therefore, existing vacuum smelting fast solidification stove has many improved technology and device to blower fan, as strengthening bearing, bearing and magnetic fluid isolated, even the outside increase again on cooling jacket, the result still is that accident is continuous.
In a word, the blower fan structure on the existing vacuum smelting fast solidification stove is loaded down with trivial details, and fault is more, thereby reduces transmission efficiency; The labor energy and time in real work, inefficiency; Maintenance and replacing are inconvenient, and maintenance frequency is many, increase maintenance cost; Therefore, production can not stable operation, causes reducing the quality of producing product and the efficient of melting work, and is poor with existing equipment compatibility, shortened service life.It is the insoluble for a long time technical barrier in this area.
In view of above-mentioned reason, the blower fan on the existing vacuum smelting fast solidification stove need be innovated improvement.
The utility model content
The purpose of the utility model is in order to overcome deficiency of the prior art, to provide a kind of vacuum melting furnace to use air draft mechanism, reduces the fan trouble of melting work, and reduces maintenance and maintenance cost, maintenance, change convenient; Good with existing equipment compatibility, guarantee that production run is reliable and stable, make and get rid of that sheet cooling is fast, quality is good; Greatly energy savings and time, obviously increase work efficiency and product quality.
The utility model is in order to realize above-mentioned purpose, adopt following technical scheme: a kind of vacuum melting furnace is used air draft mechanism, is by draught fan impeller, counter flange; Magnetic fluid, shaft coupling, motor cylinder base, motor; Machine shaft, the magnetic fluid rotating shaft, the cooling water inlet pipe, cooling water outlet pipe constitutes; One end of motor is provided with columnar motor cylinder base, and an end of motor cylinder base is provided with counter flange, counter flange middle part preformed hole; Machine shaft is set, the coaxial magnetic fluid that is provided with in the chamber of motor cylinder base in the motor; The magnetic fluid rotating shaft is set, the coaxial corresponding shaft coupling that is provided with between magnetic fluid rotating shaft and the machine shaft in the magnetic fluid; The other end of magnetic fluid rotating shaft is through the coaxial draught fan impeller that is provided with of the preformed hole of counter flange, and draught fan impeller is arranged on the outside of counter flange.
Between magnetic fluid and the motor cylinder base bottom at least one cooling water inlet pipe is set, between magnetic fluid and the motor cylinder base top at least one cooling water outlet pipe is set.
The beneficial effect of the utility model is: simple in structure, reasonable in design, and safety easy to use, swift to operate; Reduce the fan trouble of melting work, and reduce maintenance and maintenance cost, it is convenient to keep in repair, change; Good with existing equipment compatibility, guarantee that production run is reliable and stable, make and get rid of that sheet cooling is fast, quality is good; Greatly energy savings and time, obviously increase work efficiency and product quality.
Simple in structure: the utility model connects draught fan impeller and motor through a magnetic fluid, saves the bearing fan of original structure and the multiple parts such as magnet of power transmission shaft and magnetic running part.Therefore, avoided original blower fan, caused the situation of pausing of producing because of structure problem often damages because of bearing running hot in the course of the work.Thereby make the reliable, stable of cooling blower running, accelerated to get rid of the cooling velocity of sheet and improved product quality.Thereby guarantee the efficient of melting work.
Minimizing produces the factor of fault: because the required number of parts of this structure reduces, the factor that produces fault has also just decreased, and installation and maintenance are all more convenient.Under reliable, the stable case of equipment operation, just practice thrift the energy and the time of additional waste greatly like this, reduced labour intensity; Simultaneously, prolonged service life.
Reduce production costs: the design adopts part to significantly reduce than in the past, adopts magnetic fluid directly to connect with draught fan impeller at the running part of blower fan, cancels original bearing block, bearing and water jacket part.Raw material and processing charges have lacked many relatively.Invest lowly, be convenient to promote.
Good with existing equipment compatibility: variation is little on the existing equipment basis, can change arbitrarily with most of parts of existing vacuum melting rapid hardening spun furnace, is convenient to the batch process of these parts, and the parts price of batch process is low, reduces maintenance cost.
The utility model has solved the insoluble for a long time technical barrier in this area adaptable across the heat-exchange system of spun furnace, has satisfied market and user's demand.
