Description

Technical Field

[0001] The present invention relates to the technical field of smelting furnaces, and particularly to a temperature self-adjusting smelting furnace for titanium alloy production. Background Art

[0002] The metal manufacturing industry has always been one of the pillar industries in the country. Among them, melting, cutting, and grinding are several commonly used processing methods in the metal manufacturing process. During the metal melting process, the smelting furnace is the most commonly used metal melting equipment. The smelting furnace melts the metal ingot into metal slurry by high-temperature heating, and then injects the metal slurry into the corresponding mold to complete the processing of the metal.

[0003] The existing smelting furnaces usually adopt the way of overall smelting to melt the metal raw materials, but the heating time required for overall smelting is relatively long, and long-time heat conduction is needed. And during smelting, the metal with a relatively low temperature is usually directly put into the smelting pot, which further reduces the smelting efficiency and consumes more energy. Summary of the Invention

[0004] The purpose of the present invention is to provide a temperature self-adjusting smelting furnace for titanium alloy production to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A temperature self-adjusting smelting furnace for titanium alloy production, including a furnace body. A furnace cover is arranged on the top of the furnace body. A preheating chamber and a smelting chamber are arranged inside the furnace body. The preheating chamber is located above the smelting chamber, and a discharging chamber is arranged at the bottom of the smelting chamber.

[0007] Preferably, one side of the preheating chamber close to the smelting chamber is hemispherical. A plurality of spring plates are arranged inside the preheating chamber. One end of the spring plate close to the preheating chamber is provided with a rotating shaft, and a torsion spring is arranged on the rotating shaft. The spring plate is rotationally connected to the inner wall of the preheating chamber through the rotating shaft.

[0008] When the smelting chamber smelts the metal, the heat generated by smelting is conveyed to the side close to the preheating chamber. The heat is conducted to the spring plate and transferred to the surface of the metal stored in the preheating chamber through the spring plate. At this time, the preheating chamber plays a role of storage. Affected by the heat of smelting, the temperature of the metal surface rises, thus achieving the preheating effect and improving the smelting efficiency.

[0009] Preferably, the smelting chamber is composed of a plurality of vertical grooves. The tops of the plurality of vertical grooves converge and communicate with the preheating chamber. A smelting pot is arranged at the bottom of the vertical groove. The smelting pot is rotationally connected to the vertical groove. The top area of the vertical groove is larger than the bottom area of the vertical groove.

[0010] By setting up several vertical slots and connecting all the vertical slots with the preheating chamber, the vertical slots can be divided into zones for metal smelting. By using a small amount and multiple smelting method, the smelting time is saved compared with overall smelting. The raw materials in the preheating chamber are transported to the vertical slots through the spring plate. Since the top area of ​​the vertical slots is larger than the bottom area of ​​the vertical slots, the raw materials fall into the smelting pot through the vertical slots.

[0011] Preferably, a heating coil is arranged on the inner wall of the vertical groove, and the heating coil is arranged in a ring shape around a single vertical groove. A rotating motor is arranged at the bottom of the vertical groove, and a driving shaft of the rotating motor is connected to a rotating shaft of the smelting pot.

[0012] After the raw materials fall into the smelting pot, the controller controls the heating coil to start, and the heat generated by the heating coil is conducted to the raw materials. Different vertical slots can be set with different heating temperatures through the controller to adapt to different raw material melting points and achieve the function of temperature self-adjustment. In addition, the vertical slots are used for zoned heating. Compared with overall heating, the efficiency of heat conduction is improved, the time required for heating the raw materials to the melting point is reduced, the efficiency of raw material smelting is improved, and energy consumption is saved. After the raw materials are smelted, the controller controls the rotation motor to start, and the driving shaft of the rotation motor drives the rotation shaft of the smelting pot to rotate, and the smelting pot rotates toward the discharge chamber.

[0013] Preferably, the discharge cavity is composed of a plurality of chutes and output chutes, the chutes are located at the bottom of the smelting pot, the chutes correspond to the smelting pot one by one, one end of the chutes away from the output chutes is connected to the output chutes, and a casting mold is provided at the bottom of the output chutes;

[0014] After the metal in the smelting pot is melted, the smelting pot rotates to the side close to the chute. During the rotation of the smelting pot, the molten metal flows to the chute, then flows to the output chute through the chute, and finally flows into the casting mold. By setting up multiple chute, the smelting pot can pour out the molten metal continuously, and then the molten metal is output through different chute, which improves the smelting efficiency. If the mold to be cast requires more molten metal, several smelting pots can rotate synchronously, so that the molten metal output from several chutes is gathered in the output chute and output together.

[0015] Preferably, a plurality of toggle assemblies are provided on one side of the furnace cover close to the preheating chamber, and the toggle assemblies are composed of a transmission shaft, a moving ring, a pushing ring and two centrifugal balls.

[0016] Preferably, a No. 1 motor is provided inside the furnace cover, the driving shaft of the No. 1 motor is connected to the transmission shaft, a slide groove is provided on the shaft wall of the transmission shaft, a slider is provided on the inner wall of the movable ring and the push ring, and the movable ring and the push ring are rotatably connected to the transmission shaft through the slide groove and the slider.

[0017] Preferably, the moving ring is located above the pushing ring, and centrifugal balls are arranged between the moving ring and the pushing ring. The centrifugal balls are respectively hinged to the moving ring and the pushing ring through hinge rods, and a pushing head is arranged on the side of the pushing ring away from the transmission shaft.

[0018] After the raw materials are input into the preheating chamber, at this time, the spring plate separates the vertical groove from the preheating chamber, so that the raw materials cannot be transported from the preheating chamber to the vertical groove. When the furnace cover covers the preheating chamber, the preheating chamber immediately forms a closed chamber. During the initial process of adding raw materials, the first motor is not started. At this time, the pushing head presses the spring plate downward, that is, the preheating chamber and the vertical groove are in a communicating state. After a part of the raw materials enter the preheating chamber, they are immediately transported to the vertical groove through the preheating chamber. When the raw materials in the vertical groove are transported, the first batch of raw materials entering the vertical groove are directly heated in the melting pot.

[0019] The controller controls the first motor to start. The drive shaft of the first motor drives the transmission shaft to rotate. When the transmission shaft rotates, it drives the centrifugal balls to rotate. The centrifugal balls rotate under the action of the transmission shaft. When the centrifugal balls rotate, they stir the raw materials in the preheating chamber, making the raw materials in a tumbling state, improving the uniform heating of the raw materials in the preheating chamber (that is, preheating the next batch and subsequent raw materials), and improving the preheating effect of the raw materials.

[0020] When the molten metal in the melting pot is poured and the next melting is required, at this time, the controller controls the corresponding first motor to reduce the speed. Since the centrifugal force generated by the transmission shaft weakens the force acting on the centrifugal balls after the speed is reduced, the centrifugal balls move toward the side close to the transmission shaft. After the centrifugal balls contract inward, they push the moving ring and the pushing ring to move in the opposite direction through the hinge rods, so that the pushing ring drives the pushing head to move toward the side close to the spring plate. The pushing head pushes the spring plate to move toward the side close to the vertical groove, so that the preheating chamber is communicated with the vertical groove. Then, the raw materials in the preheating chamber fall into the melting pot through the gap between the spring plate and the preheating chamber, so as to achieve the addition of raw materials in small amounts and multiple times at intervals. When the raw material addition is completed, the first motor starts again, the pushing head moves away from the spring plate under the action of the pushing ring, and the spring plate returns to its original position under the action of the torsion spring, so that the preheating chamber and the vertical groove are separated again.

[0021] Preferably, an air delivery groove is arranged at the top of the melting chamber, an air delivery pipe is arranged between adjacent two vertical grooves, an air storage chamber is arranged at the center of several vertical grooves, one end of the air delivery pipe communicates with the air delivery groove, the other end of the air delivery pipe communicates with the air storage chamber, an air jet port is arranged on the side of the air storage chamber close to the melting pot, a valve is arranged in the air jet port, an air pump is arranged in the air storage chamber, the air pump is respectively communicated with the preheating chamber and the air delivery pipe through pipelines, and the jet direction of the air jet port coincides with the tangent direction of the top of the melting pot.

[0022] During the process of melting metal, certain steam is generated. The steam flows from the bottom of the vertical groove to the top of the vertical groove. When the steam moves between the vertical groove and the spring plate, the controller controls the air pump to start. The air pump extracts gas and transports it through the air delivery groove to the air delivery pipe, and then through the air delivery pipe to the gas storage cavity. Since the air pump is also connected to the preheating cavity through a pipeline, the raw materials are transported to the preheating cavity. After the furnace cover closes the preheating cavity, the air pump extracts the air in the preheating cavity, making the preheating cavity in a sealed state. Due to the continuous input of gas into the gas storage cavity, the air pressure in the gas storage cavity increases. When one of the melting pots pours the molten metal into the inclined groove, at this time, the axis of the melting pot is parallel to the axis of the jet nozzle, that is, the jet direction of the jet nozzle coincides with the tangent direction of the top of the melting pot. Subsequently, the controller controls the valve in the jet nozzle to open, and the gas in the gas storage cavity is ejected towards the melting pot under the action of air pressure. Furthermore, the gas is ejected towards the melting pot in a tangential direction, and the gas conducts cleaning and cooling treatment on the melting pot;

[0023] Preferably, a disassembly plate is arranged between two adjacent spring plates;

[0024] By setting the disassembly plate, when different alloys need to be melted separately, several disassembly plates divide the preheating cavity into multiple small chambers. Coupled with the one-to-one correspondence between the vertical grooves and the spring plates, the melting furnace can synchronously melt multiple alloys. Then, through distribution and output, the output of molten metal with different compositions is realized, thus saving the number of melting furnaces; when melting one alloy, the disassembly plate is removed, and then the preheating cavity forms an integral space, thereby accelerating the metal melting efficiency.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. By setting several vertical grooves and the preheating cavity communicating with all the vertical grooves, the vertical grooves can conduct metal melting in zones. Through the melting method of small amounts and multiple times, compared with overall melting, the melting time is saved. By setting the disassembly plate, when different alloys need to be melted separately, several disassembly plates divide the preheating cavity into multiple small chambers. Coupled with the one-to-one correspondence between the vertical grooves and the spring plates, the melting furnace can synchronously melt multiple alloys. Then, through distribution and output, the output of molten metal with different compositions is realized, thus saving the number of melting furnaces and reducing the energy consumption.

[0027] 2. Collect the steam generated by the preheating cavity and melting. After the raw materials are melted and output, gas is discharged towards the melting pot through the jet nozzle. The impact force of gas compression is used to clean the melting pot, improving the utilization rate of steam. At the same time, the steam is stored in the gas storage cavity, playing a certain heat preservation effect.

[0028] 3. When the smelting chamber is smelting the metal, the heat generated by the smelting is transported to the side close to the preheating chamber, and the heat is conducted to the spring plate, and then transferred to the metal surface stored in the preheating chamber through the spring plate. At this time, the preheating chamber plays a storage role, and the metal is affected by the heat of smelting, and the temperature of the metal surface rises, thereby achieving the preheating effect, further improving the efficiency of smelting and saving energy consumption.

[0048] The working principle of the present invention:

[0049] After the raw materials are input into the preheating cavity 12, at this time, the spring plate 15 separates the vertical groove 16 from the preheating cavity 12, so that the raw materials cannot be transported from the preheating cavity 12 to the vertical groove 16. When the furnace cover 11 covers the preheating cavity 12, the preheating cavity 12 immediately forms a closed chamber. During the initial process of adding raw materials, the first motor is not started. At this time, the pushing head 25 presses the spring plate 15 downward, that is, the preheating cavity 12 and the vertical groove 16 are in a communicating state. After a part of the raw materials enter the preheating cavity 12, they are immediately transported to the vertical groove 16 through the preheating cavity 12. When the raw materials in the vertical groove 16 are transported, the first batch of raw materials entering the vertical groove 16 are directly heated in the smelting pot 17;

[0050] The controller controls the first motor to start. The drive shaft of the first motor drives the transmission shaft 21 to rotate. When the transmission shaft 21 rotates, it drives the centrifugal ball 24 to rotate. The centrifugal ball 24 rotates under the action of the transmission shaft 21. When the centrifugal ball 24 rotates, it stirs the raw materials in the preheating cavity 12, so that the raw materials are in a tumbling state, and the raw materials are uniformly heated in the preheating cavity 12 (that is, the next batch and subsequent raw materials are preheated);

[0051] When the molten metal in the melting pot 17 is poured and the next melting is required, the controller controls the corresponding first motor to reduce the speed. After the speed is reduced, the centrifugal force generated by the transmission shaft 21 acting on the centrifugal ball 24 weakens, causing the centrifugal ball 24 to move towards the side closer to the transmission shaft 21. After the centrifugal ball 24 contracts inward, it pushes the moving ring 22 and the pushing ring 23 to move towards the opposite side through the hinge rod, causing the pushing ring 23 to drive the push head 25 to move towards the side closer to the spring plate 15. The push head 25 pushes the spring plate 15 to move towards the side closer to the vertical groove 16, making the preheating chamber 12 communicate with the vertical groove 16. Then, the raw materials in the preheating chamber 12 fall into the melting pot 17 through the gap between the spring plate 15 and the preheating chamber 12, thus achieving the addition of raw materials in small amounts and multiple times at intervals. When the addition of raw materials is completed, the first motor starts again, and the push head 25 moves away from the spring plate 15 under the action of the pushing ring 23. The spring plate 15 then resets under the action of the torsion spring, separating the preheating chamber 12 and the vertical groove 16 again;

[0052] After the raw materials fall into the melting pot 17, the controller controls the heating coil to start. The heat generated by the heating coil is conducted into the raw materials. Different vertical grooves 16 can be set with different heating temperatures through the controller, thereby adapting to different melting points of the raw materials and achieving the function of self-adjusting temperature. Moreover, by heating in zones through the vertical grooves 16, compared with overall heating, the heat conduction efficiency is improved, the time required for heating the raw materials to the melting point is reduced, and the melting efficiency of the raw materials is improved. After the raw materials are melted, the controller controls the rotation motor to start. The drive shaft of the rotation motor drives the rotation shaft of the melting pot 17, and the melting pot 17 rotates towards the discharge chamber 14;

[0053] After the metal in the melting pot 17 is melted, the melting pot 17 rotates towards the side closer to the inclined groove 18. During the rotation of the melting pot 17, the molten metal contained flows towards the inclined groove 18, and then flows towards the output groove 19 through the inclined groove 18, and finally flows into the casting mold. By setting multiple inclined grooves 18, the melting pot 17 can continuously pour out the molten metal. Then, the molten metal is output through different inclined grooves 18, improving the melting efficiency. If the mold to be cast requires more molten metal, several melting pots 17 can rotate synchronously, so that the molten metal output from several inclined grooves 18 converges in the output groove 19 and is output together;

[0054] Since a certain amount of steam is generated during the process of smelting metal, the steam flows from the bottom of the vertical groove 16 to the top of the vertical groove 16. When the steam moves between the vertical groove 16 and the spring plate 15, the controller controls the air pump to start. The air pump extracts gas and transports it through the air delivery groove 26 to the air delivery pipe 27, and then transports it into the air storage cavity 28 through the air delivery pipe 27. Since the air pump is also connected to the preheating cavity 12 through a pipeline, when the raw materials are transported to the preheating cavity 12 and the furnace cover 11 closes the preheating cavity 12, the air pump extracts the air in the preheating cavity 12, making the preheating cavity 12 in a sealed state. Since gas is continuously input into the air storage cavity 28, the air pressure in the air storage cavity 28 increases. When one of the melting pots 17 pours the molten metal into the inclined groove 18, at this time, the axis of the melting pot 17 is parallel to the axis of the air jet port 29, that is, the jet direction of the air jet port 29 coincides with the tangent direction of the top of the melting pot 17. Subsequently, the controller controls the valve in the air jet port 29 to open, and the gas in the air storage cavity 28 is ejected towards the melting pot 17 under the action of air pressure. Furthermore, the gas is ejected towards the melting pot 17 in a tangent direction, and the gas conducts cleaning and cooling treatment on the melting pot 17;

[0055] By setting the disassembly plate 30, when it is necessary to separately smelt different alloys, several disassembly plates 30 divide the preheating cavity 12 into multiple small chambers. Coupled with the one-to-one correspondence between the vertical groove 16 and the spring plate 15, the smelting furnace can synchronously smelt multiple alloys, and then through distribution and output, the output of molten metal with different components is realized, thus saving the number of smelting furnaces; when it is necessary to smelt one alloy, the disassembly plate 30 is removed, and then the preheating cavity 12 forms an integral space, thereby accelerating the metal smelting efficiency.

[0056] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
