Description

Technical Field

[0001] The present invention relates to the technical field of melting furnaces, and more particularly to a continuous zinc alloy centralized melting system. Background Art

[0002] The zinc alloy melting furnace is a new type of high-efficiency and energy-saving zinc melting furnace developed based on the zinc smelting process. It is mainly used for melting and heat preservation of zinc ingots, and it can well meet the zinc smelting process. The furnace consists of a melting furnace, crucible, heating elements, furnace cover lifting mechanism, and heat preservation system.

[0003] After searching, a continuous aluminum alloy centralized melting device with the announcement number CN114294958B is found, which includes: a melting furnace and an insulation device connected to the output end of the melting furnace and capable of accommodating molten aluminum liquid. The first outer shell is arranged outside the second outer shell through a first outer shell ring, and the first heating wire is wound around the outside of the second outer shell. The first driving part drives the second outer shell to rotate, and the first heating wire is energized, which can heat the second outer shell in all directions, and through the rotation of the second outer shell, the aluminum liquid therein is driven to shake, thereby preventing a single area of ​​the aluminum liquid from being heated for too long and uneven heating, thereby improving the subsequent mold production quality.

[0052] For example 1, please refer to Figure 1-17 , the present invention provides the following technical solutions:

[0055] Working principle of this embodiment 1:

[0056] This application utilizes the technology of electromagnetic stirring. The working principle of electromagnetic stirring is to transmit ultra-low frequency alternating current to the induction coil of the electromagnetic inductor through a variable frequency power supply. The iron core of the inductor generates a traveling wave magnetic field. When the traveling wave magnetic field penetrates the bottom wall of the smelting furnace and acts on the molten metal, the molten metal will produce a regular flow under the action of the Lorentz magnetic force, thereby achieving the purpose of stirring the molten metal, which can effectively solve the quality problems of metal products such as segregation, shrinkage, and formation of columnar crystals.

[0057] The specific technical solution is to transport the molten zinc in the melting furnace 1 into the insulation furnace 2 for insulation storage. When the workers need it, they only need to take the molten zinc from the insulation furnace 2 without shutting down the melting furnace 1, thereby realizing on-demand use and continuous melting of the zinc alloy, thereby improving production efficiency; through the use of the electromagnetic stirring part 11 and the electromagnetic heating part 16, the molten zinc is stirred while being melted and insulated; through the linkage between the various components, the electromagnetic heating part 16 and the electromagnetic stirring part 11 are synchronously swung back and forth, so that the direction of the magnetic field formed by the stirring coil 19 and the annular wavy heating coil 21 changes synchronously (the two always remain perpendicular to each other), thereby changing the flow direction of the molten zinc and further improving the stirring effect.

[0061] A ring gear 34 is fixed to the bottom of the rotating ring 32; a connecting plate is fixed to the inner wall of the annular cover 4; a rotating shaft 35 is rotatably provided on the surface of the support plate; a driving gear 36 that meshes with the ring gear 34 is fixed to one end of the rotating shaft 35; a first bevel gear 37 is fixed to the other end of the rotating shaft 35; a connecting shaft 38 is rotatably provided on the inner wall of the annular cover 4; a second bevel gear 39 that meshes with the first bevel gear 37 is fixed to one end of the connecting shaft 38; a servo motor 40 is fixedly installed on the outer peripheral side of the annular cover 4; the output end of the servo motor 40 is fixedly connected to the other end of the connecting shaft 38 through a reducer.

[0062] A C-shaped upper guide ring 41 and a C-shaped lower guide ring 42 coaxial with the inner circumference of the swivel 32 are fixed; an extension plate 43 is symmetrically fixed to the C-shaped upper guide ring 41, the C-shaped lower guide ring 42 and the inner circumference of the swivel 32; a guide channel 44 for sliding cooperation with the slide rod 13 is formed between the C-shaped upper guide ring 41 and the C-shaped lower guide ring 42; a first curved guide plate 45 is fixed to the bottom surface of the C-shaped upper guide ring 41; a second curved guide plate 46 is fixed to the surface of the C-shaped lower guide ring 42; the first curved guide plate 45 is placed directly above the avoidance gap formed at both ends of the C-shaped lower guide ring 42; the second curved guide plate 46 is placed directly below the avoidance gap formed at both ends of the C-shaped upper guide ring 41.

[0063] A sealing cover 62 is screwed to the inner side surface of the annular cover 4; two mounting seats 63 are symmetrically fixed on the surface of the sealing cover 62; a delivery pump 64 is fixedly mounted on the two mounting seats 63; a discharge pipe 65 and a feed pipe 66 are provided through the top of the holding furnace 2; the output end of one delivery pump 64 is connected to a first delivery pipe 67, and its input end and the discharge pipe 65 are connected to a first extraction pipe 68; the input end of the other delivery pump 64 is connected to a discharge pipe 69 and the feed pipe 66, and its output end is connected to a second delivery pipe 70; a second extraction pipe 71 is connected between the output end of the melting furnace 1 and the second delivery pipe 70.

[0064] Working principle of the second embodiment:

[0065] The so-called star connection, also known as the "Y" connection, connects one end of the three windings of the motor stator together and the other end of each winding to three-phase AC power. Its name comes from its resemblance to the shapes of a "Y" and an "*." Because the star connection connects three phases of power 120° out of phase through the coils, when the three phases are balanced, their common connection point cancels out each other, forming a "zero" point. The neutral line plays a crucial role in the star connection. First, it acts as a bridge connecting the various load devices. By connecting the neutral points of each device to a common lead, current distribution and guidance are facilitated. Second, the neutral line also serves to balance current. Due to the operating conditions of different load devices,

[0066] The magnetic field direction of the annular wavy heating coil 21 is horizontal, one end of each annular wavy heating coil 21 is connected to the three-phase output of the heating power supply, and the other end of each annular wavy heating coil 21 is grounded; a number of grooves are evenly opened on the magnetic yoke 18, and each group of stirring coils 19 is arranged in the corresponding groove of the magnetic yoke 18. Adding a magnetic yoke 18 in the middle of the stirring coil 19 can increase the strength of the stirring magnetic field. The magnetic field direction of the stirring coil 3 is vertical, and the two magnetic fields are perpendicular to each other. There is no induced electromotive force, which avoids the coupling of the magnetic field of the annular wavy heating coil 21 and the magnetic field of the stirring coil 19. The annular wavy heating coil 21 is decoupled by being arranged perpendicular to the stirring coil 19, so that melting and insulation can be carried out while stirring, and there will be no mutual influence due to electromagnetic field coupling. The specific working principle can be seen in the announcement number CN114294958B, a ready-to-use continuous aluminum alloy centralized melting device, which will not be elaborated here.

[0067] Fix the ear plate 23 on the electromagnetic assembly 5 to the mounting plate 22 by tightening bolts, screw the sealing cover 62 to the top of the annular cover 4, and connect the output end of the melting furnace 1 to the conveying pipe 67 through the second extraction pipe 71 to complete the assembly of the electromagnetic assembly 5.

[0068] By starting the corresponding delivery pumps 64, the zinc melt heated and melted inside the melting furnace 1 is delivered to the holding furnace 2 through the second extraction pipe 71 and the second delivery pipe 70 in sequence. When the workers need it, they only need to take the zinc melt from the holding furnace 2 (that is, control and start another set of delivery pumps 64 to extract the zinc melt in the holding furnace 2 through the first extraction pipe 68 and discharge it through the first delivery pipe 67). Valves are provided on the first delivery pipe 67, the first extraction pipe 68, the discharge pipe 69 and the second delivery pipe 70, and there is no need to close the melting furnace 1, thereby realizing on-demand use and continuous melting of the zinc alloy, thereby improving production efficiency.

[0069] By controlling and starting the servo motor 40, the connecting shaft 38 is driven to rotate slowly, thereby driving the second bevel gear 39 to rotate slowly, and then driving the first bevel gear 37 to rotate slowly, thereby driving the driving gear 36 to rotate through the rotating shaft 35, and then driving the ring gear 34 to rotate slowly. In the initial state, the four groups of slide bars 13 are all arranged inside the guide channel 44. At this time, each group of arc springs maintains a normal state, and the positioning ring 12 together with each group of stirring coils 19 and the annular wavy heating coil 21 are all coaxially sleeved on the outside of the insulation furnace 2; when the ring gear 34 slowly rotates until a group of slide bars 13 (denoted as slide bars 13A) disengages from the guide channel 44, the corresponding second curved guide plate 46 moves toward the direction close to the slide bar 13A, so that the slide bar 13A is lifted and the corresponding arc spring is compressed; the other group of slide bars 13 (denoted as slide bars 13a) opposite to the slide bar 13A is ) also just leaves the guide channel 44, and the corresponding first curved guide plate 45 slides toward the direction close to the slide bar 13a, so that the slide bar 13a is pressed down and the corresponding arc spring is stretched. The remaining two groups of opposite slide bars 13 (respectively recorded as slide bar 13B and slide bar 13b) are placed inside the guide channel 44, the slide bar 13A is lifted, and the slide bar 13a is synchronously pressed down, so that the electromagnetic stirring part 11 as a whole rotates around the corresponding rotating ring 14 on the slide bar 13B and the slide bar 13b. During this process, the direction of the magnetic field of the stirring coil 19 changes, thereby changing the direction of the Lorentz magnetic force and the flow direction of the zinc melt, further improving the stirring effect, and at the same time ensuring that the magnetic field of the stirring coil 19 and the magnetic field of the annular wavy heating coil 21 are always perpendicular to each other, avoiding the coupling of the magnetic field of the annular wavy heating coil 21 with the magnetic field of the stirring coil 19.

[0070] To sum up, as the ring gear 34 rotates slowly, the electromagnetic heating part 16 and the electromagnetic stirring part 11 synchronously perform periodic reciprocating swings, so that the directions of the magnetic fields formed by the stirring coil 19 and the annular wavy heating coil 21 change synchronously (the two always remain perpendicular to each other), thereby changing the flow direction of the zinc melt, improving the stirring effect, and enhancing the production quality of the smelting product.

[0071] For example three, please refer to Figure 1-17The third embodiment is improved on the basis of the second embodiment as follows: specifically, an annular guide plate 47 is fixed to the bottom surface of the gear ring 34; a plurality of curved guide grooves 48 are evenly opened on the bottom surface of the annular guide plate 47; a plurality of heat exchange tubes 49 are evenly fixed to the surface of the support plate 3; a plurality of heat exchange protrusions are evenly fixed to the outer peripheral side of the heat exchange tube 49; a first annular tube 50 is fixed to the outer peripheral side of the annular cover 4; a cold water inlet pipe 51 and a cold water outlet pipe 52 are sequentially connected to the outer peripheral side of the first annular tube 50; a water pumping pipe 53 is connected between the first annular tube 50 and each heat exchange tube 49; a second annular tube 50 is fixed to the bottom of the annular cover 4 4; a water outlet pipe 55 is provided on the outer peripheral side surface of the second annular tube 54; a drain pipe 56 is provided between the second annular tube 54 and the bottom of each heat exchange tube 49; a one-way valve is provided on the drain pipe 56 and the water pumping pipe 53; the top of the heat exchange tube 49 is opened, and a piston portion 57 is slidably provided inside the heat exchange tube 49; the piston portion 57 includes a piston plate 58 that slides with the heat exchange tube 49; a piston rod 59 is fixed on the top of the piston plate 58; a guide ball 60 that is adapted to the curved guide groove 48 is fixed on the top of the piston rod 59; a return spring 61 is fixedly connected between the piston plate 58 and the inner bottom surface of the heat exchange tube 49.

[0072] Working principle of the third embodiment:

[0073] The control guide portion 17 is controlled to rotate slowly, and the annular guide plate 47 at its bottom is driven to rotate slowly during the process. Under the elastic force of the return spring 61, the guide ball 60 is driven to always be close to the bottom of the annular guide plate 47. When the curved guide groove 48 rotates to above the guide ball 60, the guide ball 60 is driven to always be close to the curved guide groove 48 under the elastic force of the return spring 61. During the rotation of the guide portion 17, the return spring 61 is cooperated to realize the periodic reciprocating rise and fall of each group of piston parts 57 in the corresponding heat exchange tube 49, and the cold water is transported to the inside of the first annular tube 50 through the cold water inlet pipe 51. , discharged through the cold water outlet pipe 52, ensuring that there is a constant supply of cold water inside the first annular tube 50, and by arranging a one-way valve on the drain pipe 56, the hot water after heat exchange inside the heat exchange tube 49 can only be discharged into the second annular tube 54 through the drain pipe 56, and through the water outlet pipe 55.
