Description

Technical Field

[0001] The utility model relates to the relevant field of electric permanent magnetic stirrers, in particular to a bottom-mounted electric permanent magnetic stirrer for a smelting furnace. Background Art

[0002] In the process of metal smelting or melting, it is usually necessary to fully stir the liquid metal. There are three ways of stirring: mechanical stirring, air blowing, and magnetic stirring. The magnetic stirring method has been increasingly widely used because of its advantages such as controllable stirring mode and no direct contact with the melt.

[0003] At present, in the process of metal smelting, stirring can improve the melting efficiency of metal objects, solve the uneven temperature between the melts in the furnace, and overcome the oxidation and burning caused by the uneven temperature in the smelting process. By fully stirring the metal liquid, the alloy composition in the metal liquid can be uniform, and the impurities in the melt can be discharged through stirring;

[0004] The magnetic fields of the commonly used furnace bottom magnetic stirrers are electromagnetic and permanent magnet. There are two types of existing electromagnetic stirrers. One is that the electromagnetic stirrer is fixed, and the excitation current is provided by a low-frequency alternating power supply to obtain a rotating or spiral magnetic field. This stirrer consumes a lot of energy, and the supporting equipment is expensive and complicated, and its promotion is limited. The other is that a rotating magnetic field is generated by the rotation of an electromagnet. It has a simple structure but relatively high energy consumption. For this reason, it is necessary to set up a bottom-mounted electric permanent magnet stirrer to achieve energy-saving and efficient stirring. At the same time, efficient heat dissipation can be achieved to avoid internal overheating and parts damage. Utility Model Content

[0036] Here’s how it works:

[0037] When the bottom-mounted permanent magnetic stirrer for the smelting furnace is to be used, the trolley 1 is provided with a lifting mechanism 12 and a traveling mechanism 15. The lifting mechanism 12 is provided with a lifting locking device 16 to ensure that the trolley 1 stops at a designated position and lifts the permanent magnet 5 to the height controlled by the limit device 11, and can stand stably on the ground so that the entire device is stable and does not swing when the permanent magnet 5 rotates. The supporting device 14 is fixed on the trolley 1, and supports the permanent magnet 5 to rotate normally at a high speed through the rotating support. The supporting shaft 7 cooperates with the supporting device 14 and the rotating support 6 through the rotating mechanism 4. The lead-out cable of the permanent magnet 5 is connected to the collector slip ring assembly 8 installed on the supporting shaft 7 through the supporting shaft 7. In addition, in order to ensure that the permanent magnet 5 can work normally, a cooling fan 3 is also installed on the trolley 1, and a thermocouple 10 is installed in the cover 13 to monitor and cool the temperature in the cover 13.

[0038] Among them, Figure 7 and Figure 8 The electric permanent magnet 5 shown can be installed in the form of a group of vertical electric permanent magnet coils and a group of horizontal electric permanent magnet coils, so as to achieve efficient electromagnetic stirring and accelerate the rapid stirring and discharge of impurities in the melt inside the smelting furnace;

[0039] In order to speed up the heat dissipation of the cover body 13, an adjustable heat dissipation device 17 is provided at the upper end of the cover body 13 to assist in realizing flexible adjustment of heat dissipation coordination. That is, when heat dissipation is required, the rotating shaft 17a1 installed in the intermittent structure 17a can be rotated to rotate the rotating shaft 17a1 and realize the synchronous rotation of the transmission wheel 17a2 arranged on the outer side of the middle part. As the transmission wheel 17a2 rotates, the transmission grooves 17a3 symmetrically arranged at the front and rear ends of the outer side of the transmission wheel 17a2 will cooperate with the rotation effect to transmit the convex shafts equidistantly arranged on the outside of the turntable 17a4 arranged at the bottom, so that the turntable 17a4 can realize intermittent rotation as a whole. When the turntable 17a4 intermittently rotates, the screw 1741 connected to the middle part of the turntable 17a4 can be intermittently rotated to thread the connecting plates 1742 connected on the left and right sides, so that the connecting plates 1742 arranged on the left and right sides will cooperate with the brackets 1743 connected at the bottom to realize lateral relative movement. The push-pull rod 1744 fixedly connected to the middle of the two connecting plates 1742 will move horizontally with the two connecting plates 1742 moving relative to each other, and cooperate with the five connecting shafts 1745 plugged longitudinally in the middle to realize the transmission of the front and rear side phase transmission connecting swing arms 1746, so that the five swing arms 1746 on both sides swing synchronously and oppositely. As a result, the opening and closing plates 1747 connected to the upper ends of the five swing arms 1746 on both sides will be opened accordingly, so that the internal openings on the left and right sides of the support plate 173 are exposed. In this way, the heat generated by the driving of the internal parts of the cover body 13 can be auxiliary discharged along the heat conduction ports 172 on both sides of the bottom of the heat conduction shell 171, the openings on both sides of the support plate 173 and the openings 175 opened at the upper ends of the heat conduction ports 172, thereby helping to improve the heat dissipation effect and avoid the cover body 13 from being damaged by overheating due to excessive operating temperature, thereby achieving the advantages of auxiliary adjustable heat dissipation coordination and meeting different electromagnetic stirring conditions.

[0040] In order to ensure that external dust does not easily enter the cover body 13 during the auxiliary heat dissipation activities, a dustproof component 176 is installed at the upper end of the heat-conducting shell 171, that is, the dustproof net 1761 arranged inside the dustproof component 176 can effectively block external dust and achieve stable dustproof protection. If the dustproof net 1761 blocks a lot of dust on the outside and causes an obstruction to the auxiliary heat dissipation efficiency, the lock plate 1763 embedded in the left side plate 1762 can be pushed horizontally to move the lock plate 1763 to the right along the guide shaft 1764 plugged in the middle to achieve unlocking. In this way, the left side plate 1762 can be lifted to achieve the overall lifting of the dustproof net 1761, so that the dustproof net 1761 can be quickly moved out of the opening 175 for convenient disassembly and cleaning. When installing, the dustproof net 1761 can be positioned and assembled in advance through the positioning block 1766 provided at the bottom of the right side plate 1762, and then the locking plate 1763 is pushed horizontally again to make the locking plate 1763 squeeze the compression spring 1765 provided on the outside of the guide shaft 1764, and then inserted into the upper left side of the heat conductive shell 171. When the dustproof net 1761 is smoothly embedded in the through opening 175, the locking plate 1763 can be loosened to make the compressed compression spring 1765 rebound, and quickly push the locking plate 1763 to the left to re-insert and lock the locking plate 1763 and the upper left side of the heat conductive shell 171. In this way, the dustproof net 1761 is reinstalled for dustproof use, thereby achieving the advantages of auxiliary dust protection and reducing the occurrence of dust pollution.

[0041] The utility model provides a bottom-mounted electric permanent magnetic stirrer for a smelting furnace. An adjustable heat dissipation device 17 is provided. Under the intermittent transmission of the transmission wheel 17a2, the transmission groove 17a3 and the turntable 17a4 provided inside the intermittent structure 17a, a screw rod 1741 can intermittently drive the connecting plates 1742 provided on the left and right sides, so that the connecting plates 1742 provided on the two sides correspondingly drive the push-pull rod 1744. In this way, the five connecting shafts 1745 provided outside the push-pull rod 1744 will drive the swing arm 174 provided outside accordingly. 6. The intermittent opening of multiple locations can realize auxiliary adjustable heat dissipation coordination and enhance the heat dissipation effect, thereby achieving the advantages of auxiliary adjustable heat dissipation coordination and meeting different electromagnetic stirring conditions. A dustproof component 176 is provided, that is, the dustproof net 1761 provided inside can realize auxiliary dust protection. Under the transmission of the locking plate 1763 and the compression spring 1765, the dustproof net 1761 can be conveniently disassembled as a whole to meet the needs of convenient cleaning and use, thereby achieving the advantages of auxiliary dust protection and reducing the occurrence of dust pollution.
