Description

Technical Field

[0001] This utility model relates to the field of medium frequency furnace technology, specifically to a furnace mouth device for an aluminum electrolysis medium frequency furnace. Background Technology

[0002] In aluminum electrolysis production, during the carbon anode assembly process, the molten iron used for casting the finished anode is currently smelted in a medium-frequency furnace. During operation, an electromagnetic field is generated inside the furnace, which induces a high-frequency current in a copper conduit via an inductor. This current heats the material in the furnace, which then flows out at the furnace opening to complete the casting process. The existing technology has the following problems:

[0003] Because the existing medium-frequency furnace opening has a simple structure and fixed size, the width of the molten iron flowing out of the furnace opening is fixed each time it is poured through the inclined medium-frequency furnace. It cannot be adjusted according to the size of the casting container, which makes it easy for the large outflow to splash or overflow into the casting container. The overall furnace opening has poor applicability. At the same time, after long-term use, the existing medium-frequency furnace opening will inevitably have a small amount of solidified metal material attached to it. It is not possible to disassemble and clean the furnace opening separately, which makes the cleaning process inconvenient. Utility Model Content

[0023] For example Figure 1 , Figure 2The utility model provides a kind of aluminium electrolysis intermediate frequency furnace mouth device, including intermediate frequency furnace shell 1, the inner chamber of intermediate frequency furnace shell 1 is provided with heating mechanism 2, the top of intermediate frequency furnace shell 1 is fixedly installed with top plate 3, the front side top of heating mechanism 2 is provided with furnace end mechanism 4, heating mechanism 2 includes bottom plate 21, four fixed supports 22 are fixedly installed in the top eccentricity of bottom plate 21 with annular array, the opposite side of four fixed supports 22 is fixedly installed with a plurality of annular copper pipes 23 arranged up and down, furnace body 24 is fixedly installed at the top center of bottom plate 21, the top end of furnace body 24 is penetrated to the top center of top plate 3, furnace end mechanism 4 includes U-shaped alloy furnace end 41, the rear end of U-shaped alloy furnace end 41 is fixedly connected with the front side upper side of furnace body 24, the front end of U-shaped alloy furnace end 41 is penetrated to the front side of top plate 3 and is provided with U-shaped adjusting plate 42;

[0024] When using, by pouring raw materials into furnace body 24, it is beneficial to the power supply to the plurality of annular copper pipes 23 fixed between four fixed supports 22 to be electrified, so as to heat the inside furnace body 24, melt the raw materials, and after melting is completed, the overall intermediate frequency furnace shell 1 can be inclined at an angle, so that the metal solution is poured out through U-shaped alloy furnace end 41 and U-shaped adjusting plate 42.

[0025] As shown in Figure 3 The two perpendicular opposite surfaces of U-shaped adjusting plate 42 are provided with adjusting plate clamping grooves 421, the bottom rear side of the two adjusting plate clamping grooves 421 is movably installed with rotating adjusting plates 422, the two perpendicular top of adjusting plate clamping grooves 421 is provided with left and right through limiting sliding grooves 424, the opposite surfaces of the two rotating adjusting plates 422 are fixedly installed with arc plates 423, the two arc plates 423 are slidably connected with the two limiting sliding grooves 424 respectively, and the center of the arc plate 423 and the limiting sliding groove 424 coincides with the rotating shaft of the rotating adjusting plate 422, the two limiting sliding grooves 424 are provided with a plurality of front and rear through adjusting screw holes 425, the two perpendicular front side of U-shaped adjusting plate 42 is provided with through threaded holes 427 penetrating to the inside of limiting sliding groove 424, the inner ring thread of through threaded hole 427 is installed with limiting threaded rod 428, the rear end of limiting threaded rod 428 is penetrated to the inside of limiting sliding groove 424 and is screw-connected with the inner ring thread of one of adjusting screw holes 425 provided in arc plate 423, the end of two adjusting screw holes 425 away from rotating adjusting plate 422 is fixedly installed with limiting push plate 426;

[0026] When the size of the casting to be poured in needs to be small, the limiting of the arc plate 423 can be released by loosening the two limiting threaded rods 428, so that the two rotating adjusting plates 422 on both sides of the U-shaped adjusting plate 42 can move relative to each other under the driving of the limiting lever 426, shorten the distance between the two rotating adjusting plates 422, and align the adjusting threaded holes 425 opened on the arc plate 423 with the through threaded holes 427, and then rotate the limiting threaded rods 428 again until they are screwed into the inner threads of the newly aligned adjusting threaded holes 425, so that the position of the adjusted rotating adjusting plate 422 is fixed, and when the melted solution flows out, it can flow out between the U-shaped alloy furnace head 41 and the two rotating adjusting plates 422 inside the U-shaped adjusting plate 42, thereby shortening the width of the flowing solution and making the pouring more accurate.

[0027] As shown in Figure 4 , Figure 5 , two fixing holes 429 are opened on the bottom rear side of the U-shaped adjusting plate 42, a U-shaped clamping groove 411 is opened on the front end of the U-shaped alloy furnace head 41, a positioning box 412 is fixedly installed on the bottom front side of the U-shaped alloy furnace head 41, the rear end of the U-shaped adjusting plate 42 is clamped with the U-shaped clamping groove 411, a threaded rod 4121 is movably installed on the top center of the inner wall of the positioning box 412, a knob 4122 is fixedly installed on the bottom end of the threaded rod 4121 which penetrates through the bottom of the positioning box 412, a lifting plate 4123 is threadedly installed on the outer wall of the threaded rod 4121, the lifting plate 4123 is slidably connected with the inner cavity of the positioning box 412, two fixed insertion plates 4124 are fixedly installed on the top left and right sides of the lifting plate 4123, two butt joints 413 which penetrate into the inner cavity of the positioning box 412 are opened on the inner wall bottom left and right sides of the U-shaped clamping groove 411, and the two butt joints 413 are located above the two fixed insertion plates 4124 respectively.

[0028] When it is necessary to clean the front end of the U-shaped adjusting plate 42, the knob 4122 at the bottom of the positioning box 412 is only rotated to drive the threaded rod 4121 to rotate, so that the lifting plate 4123 in the inner cavity of the positioning box 412 moves downward by the threaded connection with the threaded rod 4121, drives the two fixed insertion plates 4124 to retract into the inner cavity of the positioning box 412 after passing through the two butt joints 413, releases the limiting of the fixing holes 429 on the bottom of the U-shaped adjusting plate 42 clamped into the U-shaped clamping groove 411, so that the whole U-shaped adjusting plate 42 can be directly taken off from the front end of the U-shaped alloy furnace head 41, and the careful cleaning is facilitated. After cleaning, the rear end of the U-shaped adjusting plate 42 can be clamped into the U-shaped clamping groove 411 opened on the front end of the U-shaped alloy furnace head 41, and the knob 4122 is reversed to drive the threaded rod 4121 to reverse, so that the lifting plate 4123 drives the two fixed insertion plates 4124 to move upward and then clamps into the fixing holes 429 after passing through the two butt joints 413, and the fixing of the U-shaped adjusting plate 42 is completed.

[0029] The working principle of the furnace mouth device of the aluminum electrolysis medium frequency furnace will be explained in detail below.

[0030] like Figures 1-5 As shown, during use, the raw material is poured into the furnace body 24. An external power source is used to energize several annular copper conduits 23 fixed between the four fixed supports 22, thereby heating the inner furnace body 24 and melting the raw material. After melting, the entire medium-frequency furnace shell 1 can be tilted at an angle, allowing the molten metal to be poured out through the U-shaped alloy furnace head 41 and the U-shaped adjusting plate 42. When the size to be poured is small, the two limiting threaded rods 428 can be loosened to release the limiting on the arc plate 423, thereby allowing the U-shaped adjusting plate to open. The two rotating adjusting plates 422 on both sides of plate 42 can be moved relative to each other by using the limiting deflector 426 to shorten the distance between the two rotating adjusting plates 422. The adjusting threaded hole 425 on the arc plate 423 is then aligned with the through threaded hole 427, and the limiting threaded rod 428 is rotated again until it is threadedly connected and fixed to the inner ring of the newly aligned adjusting threaded hole 425. This fixes the position of the adjusted rotating adjusting plate 422, allowing the molten solution to flow through the U-shaped alloy furnace head 41 and the inner ring of the U-shaped adjusting plate 42. The solution flows out between the two rotating adjustment plates 422 on the side, shortening the width of the outflow and making the casting more precise. When it is necessary to clean the front end of the U-shaped adjustment plate 42, simply rotate the knob 4122 at the bottom of the positioning box 412 to drive the threaded rod 4121 to rotate. This causes the lifting plate 4123 inside the positioning box 412 to move downward through the threaded connection with the threaded rod 4121, driving the two fixed insert plates 4124 to pass through the two docking holes 413 and retract into the inner cavity of the positioning box 412, thus releasing the U-shaped adjustment plate 42 that is stuck in the U-shaped slot 411. The bottom fixing hole 429 limits the movement of the entire U-shaped adjustment plate 42, allowing it to be removed directly from the front end of the U-shaped alloy furnace head 41 for easy cleaning. After cleaning, the rear end of the U-shaped adjustment plate 42 can be aligned with the U-shaped slot 411 at the front end of the U-shaped alloy furnace head 41 and inserted. Then, the knob 4122 is reversed, which drives the threaded rod 4121 to reverse, thereby causing the lifting plate 4123 to move the two fixing plates 4124 upward and pass through the two docking holes 413 before being inserted into the fixing hole 429, thus completing the fixing of the U-shaped adjustment plate 42.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
