Description

Technical Field

[0001] This invention relates to the field of metallurgical mixing, specifically to a TiO2 weighing and feeding device and dustproof docking device for an automatic batching and mixing apparatus. Background Technology

[0002] Vacuum consumable electrode smelting is the only metallurgical method for smelting high-performance titanium alloys. The quality of the consumable electrode used is one of the key factors determining the quality of titanium alloy products, and the mixing device is the key equipment for preparing consumable electrodes.

[0003] Titanium alloys are lightweight, high-strength, and resistant to both heat and low temperatures, making them widely used in aircraft, spacecraft, rockets, missiles, and military products. Their attractive appearance also contributes to their widespread application in everyday life. Vacuum arc remelting is the only process route for smelting high-performance titanium alloys, making the development of a series of equipment for smelting high-performance titanium alloys of particular significance.

[0004] The unique characteristics of vacuum arc remelting furnaces dictate that the mixing equipment used in the upstream process must possess excellent performance. During vacuum arc remelting, molten metal drips into the crucible's molten pool in the form of droplets, forming an ingot. As the arc remelting electrodes continuously melt and are consumed, the molten pool rises, and the molten metal gradually solidifies. Therefore, the element ratios in the arc remelting electrodes, as raw materials, must be extremely accurate, and the measurement of each alloy component must be precise. Oxygen is a crucial element affecting the properties of titanium materials and alloys. Typically, we control the oxygen content in titanium materials and alloys by adding TiO2 during the mixing stage. Therefore, accurate weighing of TiO2 and prevention of TiO2 powder dispersion are particularly important, as current feeding devices struggle to achieve accurate TiO2 weighing and prevent dust contamination. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a TiO2 weighing, feeding and dustproof docking device for an automatic mixing device. The TiO2 weighing is accurate, and the feeding process basically achieves closed docking, which greatly reduces the problem of TiO2 dust flying during the feeding process, reduces dust pollution, and has a high degree of automation.

[0006] One technical solution to achieve the above objective is: 1. A TiO2 weighing, feeding, and dustproof docking device for an automatic batching and mixing apparatus, comprising a TiO2 storage silo, a TiO2 weighing device, a screw feeder device, a telescopic receiving device, a transition discharge hopper, an electrical control box, and a support frame, characterized in that:

[0007] The TIO2 storage silo is fixed on the screw feeder device. The TIO2 storage silo device includes a storage silo body, a storage silo cover, and an internal support frame. The storage silo body is fixed on the screw feeder device, the internal support frame is fixed inside the storage silo, and the storage silo cover is fixed to the storage silo body by a round handle bolt. A sealing strip is provided between the storage silo cover and the storage silo body. The storage silo cover has an air vent and is connected to an oval feeding door by a hinge for easy manual feeding.

[0008] The screw feeder device is fixed on a support frame and includes a feeding hopper, a discharge pipe, and a screw feeding mechanism. The lower part of the feeding hopper is fixed on the support frame, and the upper part is installed below the storage hopper body. A shock-absorbing pad is installed between the feeding hopper and the support frame. The discharge pipe is fixed on the feeding hopper. The screw feeding mechanism includes a motor, a reducer, and a screw feeder. The screw feeder is installed at the lower part of the feeding hopper. The motor is driven and controlled by a frequency converter, which can effectively control the motor speed and thus control the feeding speed of the screw feeder, thereby improving the weighing accuracy of TiO2. The screw feeder rotates to move the TiO2 powder forward to the discharge port of the discharge pipe, which can effectively avoid the problem of inaccurate weighing caused by powder accumulation.

[0009] The TIO2 weighing device is located in the vertical branch of the transition feeding hopper. The TIO2 weighing device includes a weighing hopper, a weighing sensor, and a discharge gate. The weighing sensor is fixed on a bracket, the weighing hopper is fixed above the weighing sensor, and the discharge gate is located below the weighing hopper. The discharge gate is opened and closed by a cylinder.

[0010] The telescopic receiving device is fixed on the bracket and the transition feeding bucket. The telescopic receiving device includes an arc-shaped interface, a telescopic cylinder, a telescopic sleeve, and a cylinder protective cover. One end of the telescopic sleeve is connected to the arc-shaped interface, and the other end is connected to the inclined branch of the transition feeding bucket. The telescopic cylinder is used to drive the arc-shaped interface and the telescopic sleeve to move up and down. The cylinder protective cover is used to protect the cylinder from the influence of dust.

[0011] The transition feeding hopper is fixed on the support. The transition feeding hopper includes an inclined branch, a vertical branch, a cover for the vertical branch, and a feeding port. The inclined branch is connected to a telescopic receiving device and is used to receive pre-weighed sponge titanium and alloy from the inclined elevator. The vertical branch is used to receive pre-weighed TiO2 powder. The cover for the vertical branch is used to close the transition feeding hopper and is connected to the discharge port of the screw feeder to ensure that the TiO2 powder can enter the weighing hopper for weighing when the screw feeder is working. The feeding port is used to send the material from the inclined branch and the vertical branch into the mixer.

[0012] Furthermore, the TiO2 weighing and feeding and dustproof docking device is installed above the mixer support and below the discharge position of the inclined elevator via a bracket; the telescopic receiving device can dock with the discharge port of the inclined elevator hopper after it extends, and the discharge port of the transition discharge bucket can dock with the extended device of the mixer when it extends. The feeding process essentially achieves a closed docking, greatly reducing the problem of TiO2 dust flying during the feeding process.

[0013] Furthermore, it also includes a material height detection element, which is installed on the side of the storage silo body and the feeding silo.

[0014] Furthermore, it also includes an electric vibrator, which is installed on the front side of the storage silo body.

[0015] Furthermore, a pneumatic vibrator is installed at the bottom of the discharge gate. When the discharge gate is opened, the pneumatic vibrator works simultaneously, making it easier for TiO2 powder to be discharged into the mixer.

[0016] Furthermore, the unloading gate is surrounded by a sealing gasket, which prevents leakage of fine TiO2 powder.

[0017] The production process of the automatic mixing device is roughly as follows: After production begins, the TiO2 weighing device, along with the sponge titanium weighing device and the alloy weighing device, starts weighing. The reweighing trolley receives all the weighed sponge titanium and alloy into the trolley hopper and, after verifying the reweighing is correct, transports them to the receiving position of the inclined elevator. Then, all materials are unloaded into the hopper of the inclined elevator. The inclined elevator travels from the receiving position to the unloading position, decelerates, and stops at the unloading position. At this time, the telescopic receiving device extends and connects with the unloading port of the inclined elevator hopper, and the telescopic device of the mixer extends and connects with the unloading port of the transition discharge bucket, forming a sealed pipe. The hopper of the inclined elevator opens, and the material in the inclined elevator is unloaded into the mixer through the sealed pipe. The TiO2 weighing hopper opens, and the weighed TiO2 powder is unloaded into the mixer. Afterward, the telescopic receiving device retracts, the inclined elevator returns to the receiving position, the telescopic device of the mixer retracts, the mixer door closes, and mixing begins. After mixing for a certain period of time, the mixed material is discharged into the press hopper, and an automatic process is completed.

[0018] The technical effect is as follows: Fine powdered TiO2 in the TiO2 storage silo is collected at the bottom of the silo body by an electric vibrator installed on the front wall. Driven by a variable frequency drive motor, the screw feeder conveys the powdered TiO2 material to the discharge pipe, where it falls into the TiO2 weighing hopper for weighing. The signal from the TiO2 weighing device indicates the real-time weight of the TiO2 powder. The speed of the variable frequency drive can be set to fast or slow on the HMI. When the target weight of the TiO2 is approaching, a slow mode is used to reduce the rotation speed of the screw feeder, ensuring accurate material measurement.

[0019] The screw feeder uses a rotating screw mechanism to move TiO2 powder forward into the discharge pipe. Unlike mechanical vibration, it does not generate dust during material conveying and allows for more precise control of the powder discharge speed, avoiding the possibility of a pile of powder being discharged directly due to vibration. The discharge gate of the TiO2 weighing device is located at the bottom of the TiO2 weighing hopper. The gate is driven by a cylinder to open and close. The gate plate is surrounded by sealing gaskets to prevent leakage of TiO2 powder. A pneumatic vibrator is installed at the bottom of the gate plate. When the gate plate is opened, the pneumatic vibrator works simultaneously, ensuring that the TiO2 powder is completely discharged into the mixer, avoiding batching deviations caused by incomplete discharge of TiO2 powder.

[0020] The material height detection element installed on the side of the TIO2 storage silo automatically feeds back the material height signal. When the material level is low, an alarm signal is issued, prompting the operator to promptly add TIO2 to the silo. When the weight of TIO2 in the weighing device reaches the set requirement, the system immediately sends a stop signal to the PLC, causing it to stop the output of the screw feed frequency converter, ensuring weighing accuracy. After the material in the inclined elevator is unloaded into the mixer, the system automatically opens the discharge gate of the TIO2 weighing device, unloading the weighed TIO2 from the weighing silo into the mixer. This system has a high degree of automation, reducing the labor intensity of workers and improving continuous production efficiency.

[0021] During the unloading process, the telescopic receiving device extends and connects with the unloading port of the inclined elevator hopper, and the telescopic device of the mixer extends and connects with the unloading port of the transition discharge bucket, forming a sealed pipeline. This ensures that there is no leakage of sponge titanium and alloy materials in the inclined elevator and TiO2 in the TiO2 weighing hopper during the unloading process, achieving green and efficient operation and effectively solving the problem of serious dust leakage and pollution of the working environment in traditional methods.

[0024] Figure 3 This is a three-dimensional structural diagram of a weighing device for a TiO2 weighing, feeding, and dustproof docking device used in an automatic mixing apparatus according to the present invention. Detailed Implementation

[0025] Please see Figure 1 , 2 3. In order to better understand the technical solution of the present invention, the inventors of the present invention will now provide a detailed description through specific embodiments and in conjunction with the accompanying drawings:

[0026] Please see Figure 1 The present invention provides a TiO2 weighing, feeding and dustproof docking device for an automatic mixing device, comprising a TiO2 storage silo 1, a TiO2 weighing device 2, a screw feeder device 3, a telescopic receiving device 4, an electrical control box 5, a transition discharge hopper 6 and a support 7.

[0027] TiO2 powder is manually added to TiO2 storage silo 1. The TiO2 powder falls from TiO2 storage silo 1 into the feeding hopper of screw feeder device 3. The TiO2 in the feeding hopper is then transported through the discharge pipe to TiO2 weighing device 2 for weighing under the drive of the screw feeder mechanism. During the unloading process, telescopic receiving device 4 extends and connects with the discharge port of the inclined elevator hopper, and the telescopic device of the mixer extends and connects with the discharge port of the transition discharge bucket 6, forming a sealed pipeline to ensure that there is no leakage of sponge titanium and alloy materials in the inclined elevator and TiO2 in the TiO2 weighing hopper during the unloading process. The signals emitted by the measuring sensor elements of TiO2 storage silo 1, TiO2 weighing device 2, screw feeder device 3 and telescopic receiving device 4 are transmitted to electrical control box 5.

[0028] The TIO2 weighing device 2, screw feeder device 3, telescopic receiving device 4, electrical control box 5, and transition discharge hopper 6 are mounted on the bracket 7. The TIO2 storage silo 1 is mounted on the screw feeder device 3. The bracket 7 is mounted on the upper part of the mixer bracket and the lower part of the inclined elevator discharge position.

[0029] When the weight of the material in the TIO2 weighing device 2 approaches the set weight, the screw feeder operates at low speed under the drive of the frequency converter to achieve precise feeding.

[0030] Please see Figure 1 , Figure 2 The present invention discloses a TIO2 storage silo for an automatic mixing device, comprising a storage silo body 21, an internal support frame 22, a storage silo cover 23, height detection elements 28, and an electric vibrator 27. The storage silo cover 23 is fixed to the storage silo body 21 by four round handle bolts 26, and a sealing strip is installed between the storage silo cover 23 and the storage silo body 21. The storage silo cover 23 has a vent hole 24 and is connected to an oval feeding door 25 by a hinge for easy manual feeding. The electric vibrator 27 is installed on the side of the storage silo body 21. Two material height detection elements 28 are present, one installed on the side of the storage silo body 21 and the other on the side of the feeding silo 31, used to detect whether the material height of the TIO2 is high or low.

[0031] Please see Figure 1 , Figure 2 The screw feeder device in the TIO2 weighing, feeding, and dustproof docking device for an automatic mixing apparatus of the present invention includes a feeding bin 31, a discharge pipe 32, and a screw feeding mechanism 33. The upper end of the feeding bin 31 is connected to the storage bin body 21 by bolts. The bottom of the feeding bin 31 has an arc-shaped groove, in which the screw feeding mechanism 33 is installed. One end of the rotating shaft of the screw feeding mechanism 33 is inside the discharge pipe 32, and the other end is connected to a reducer 35. The reducer is driven by a variable frequency motor 34.

[0032] Open the oval feeding gate 25 and add TiO2 powder into the TiO2 storage silo 1. The TiO2 powder will fall directly into the arc-shaped groove at the bottom of the feeding silo 31 and accumulate upwards. The spiral feeding mechanism 33 in the groove starts to rotate under the drive of the variable frequency motor 34 and the reducer 35. The TiO2 powder moves towards the discharge pipe 32 as the spiral feeding mechanism 33 rotates, and falls into the TiO2 weighing silo 42 after passing through the discharge port 37 for weighing. After the spiral feeding mechanism 33 rotates and carries away the TiO2 in the groove, a hollow state is formed in the middle. When the electric vibrator 27 is powered on, it vibrates and vibrates the TiO2 powder accumulated at the top to the hollow space, ensuring that the bottom arc-shaped groove of the feeding bin 31 is filled with TiO2 powder. Each rotation of the spiral feeding mechanism 33 can transport a fixed amount of TiO2 powder to the discharge pipe 32. The rotation speed of the variable frequency motor 34 can be adjusted by controlling the frequency of the variable frequency drive, thereby adjusting the rotation speed of the spiral feeding mechanism 33, which is the speed at which the TiO2 powder is fed into the weighing bin 42. When the TiO2 in the weighing bin 42 is close to the target TiO2 weight, the speed of the variable frequency motor 34 is changed from fast to slow control until the target weight is reached and the output stops, thereby saving weighing time and achieving accurate feeding and weighing.

[0033] Please see Figure 1 , Figure 3 The TiO2 weighing device 2 of the TiO2 weighing, feeding, and dustproof docking device for an automatic mixing apparatus of the present invention includes a weighing sensor 41, a weighing hopper 42, and a discharge gate 43. The weighing sensor 41 passes through a hole in the transition feeding hopper 6 and is fixed to the bracket 7 by bolts 48. The weighing hopper 42 is located in the vertical branch of the transition feeding hopper 6 and is fixed above the weighing sensor 41 by bolts 49, without additional stress, achieving high-precision weighing. The discharge gate 43 is located at the lower part of the weighing hopper 42. A sealing gasket 45 is installed between the discharge gate 43 and the weighing hopper 42 to prevent leakage of TiO2 powder. A pneumatic vibrator 46 is installed at the bottom of the discharge gate 43. When the discharge gate 43 is opened for discharge, the pneumatic vibrator 46 works simultaneously, making it easier for the TiO2 powder to be discharged into the mixer and reducing errors caused by incomplete discharge.

[0034] The discharge gate 43 is driven by cylinder 44 to open and close. When the discharge gate 43 is open, TiO2 in the weighing hopper is discharged into the mixer. After the discharge gate 43 is closed, TiO2 weighing can begin. The upper end of cylinder 44 is connected to cylinder fixing plate 47, and the lower piston rod of cylinder 44 is connected to rotating mechanism 50. Cylinder fixing plate 47 is installed on the rear side of weighing hopper 42, and rotating mechanism 50 is installed on the discharge gate. After the weight of the material in weighing hopper 42 reaches the set weight, TiO2 weighing device 2 sends a signal to control system. Control system sends a signal to stop frequency converter motor 34, and the weight of TiO2 in weighing hopper 42 no longer increases, achieving accurate weighing. Cylinder 44 will only drive the discharge gate 43 to open and close after receiving the open and close signals from control system.

[0035] Please see Figure 1 , Figure 2 The present invention discloses a telescopic receiving device 4 for a TIO2 weighing, feeding, and dustproof docking device of an automatic mixing apparatus, comprising an arc-shaped docking interface 51, a telescopic cylinder 52, a telescopic sleeve 54, and a cylinder protective cover 53. One end of the telescopic sleeve 54 is connected to the arc-shaped docking interface 51 by a clamp, and the other end is connected to the inclined branch 61 of the transition feeding hopper 6 by a clamp. The outer end of the piston rod of the telescopic cylinder 52 is connected to the lower support plate of the arc-shaped docking interface 51, and the cylinder protective cover 53 is also connected to the lower support plate of the arc-shaped docking interface 51. The telescopic cylinder 52 can move the arc-shaped docking interface 51, the telescopic sleeve 54, and the cylinder protective cover 53 up and down by extending and retracting, while the cylinder protective cover 53 can protect the piston rod of the telescopic cylinder from the influence of dust.

[0036] Please see Figure 1 , Figure 2The transition feeding hopper 6 of the TIO2 weighing, feeding, and dustproof docking device for an automatic mixing apparatus of the present invention includes an inclined branch 61, a vertical branch 62, a vertical branch cover 64, and a feeding port 63. The inclined branch 61 is connected to the telescopic receiving device 4 and is used to receive the pre-weighed sponge titanium and alloy from the inclined elevator. The vertical branch 62 is used to receive the weighed TIO2 powder. The vertical branch cover 64 is used to close the transition feeding hopper 6. The receiving port 65 on the vertical branch cover 64 is connected to the discharge port 37 of the screw feeder device 3 to ensure that the TIO2 powder can enter the weighing hopper 42 for weighing when the screw feeder is working. The feeding port 63 is used to feed the material from the inclined branch 61 and the vertical branch 62 into the mixer.

[0037] This invention discloses a TiO2 weighing, feeding, and dustproof docking device for an automatic mixing apparatus. Fine powdered TiO2 in the TiO2 storage silo body 21 is piled up in the lower part of the silo body by an electric vibrator 27 installed on the front wall of the silo body. Driven by a variable frequency drive motor 34, a screw feeder 32 conveys the powdered TiO2 material to the discharge pipe 32, where it falls into the TiO2 weighing silo 42 through the discharge port 37 for weighing. The signal fed back by the TiO2 weighing device indicates the real-time weight of the TiO2 material. The speed of the variable frequency drive can be set to fast or slow on the HMI. When the target weight of the TiO2 is approaching, a slow mode is adopted to reduce the rotation speed of the screw feeder 32, ensuring accurate measurement of the TiO2 material.

[0038] This invention discloses a TiO2 weighing, feeding, and dustproof docking device for an automatic batching and mixing apparatus. The screw feeder 3 uses a rotating screw mechanism to move TiO2 powder forward into the discharge pipe 32. Unlike mechanical vibration, this method does not generate dust during material transport and allows for more precise control of the powder discharge speed, avoiding the possibility of a large amount of powder being discharged directly due to vibration. The discharge gate 43 of the TiO2 weighing and feeding device 2 is located at the lower part of the TiO2 weighing hopper 42. The gate is opened and closed by a cylinder 44. The gate plate 43 has sealing gaskets 45 around its perimeter to prevent leakage of TiO2 powder. A pneumatic vibrator 46 is installed at the bottom of the gate plate 43. When the gate plate 43 is opened, the pneumatic vibrator 46 operates simultaneously, ensuring that the TiO2 powder is completely discharged into the mixer, avoiding batching deviations caused by incomplete TiO2 powder discharge.

[0039] This invention discloses a TiO2 weighing, feeding, and dustproof docking device for an automatic mixing apparatus. A material height detection element 28, installed on the side of the TiO2 storage silo body 21, automatically feeds back the material height signal. When the material level is low, an alarm signal is issued to remind the operator to add TiO2 material to the TiO2 storage silo 1 in a timely manner. When the weight of TiO2 in the TiO2 weighing and feeding device 2 reaches the set requirement, the system immediately issues a stop signal to the PLC to promptly stop the output of the screw feeder frequency converter, ensuring weighing accuracy. After the material in the inclined elevator is unloaded into the mixer, the system automatically opens the discharge gate 43 of the TiO2 weighing and feeding device, unloading the weighed TiO2 from the weighing silo 42 into the mixer. This system has a high degree of automation, reduces the labor intensity of workers, and improves continuous production efficiency.

[0040] The present invention provides a TiO2 weighing, feeding, and dustproof docking device for an automatic mixing apparatus. During the unloading process, the telescopic receiving device 4 extends and docks with the unloading port of the inclined elevator hopper, and the telescopic device of the mixer extends and docks with the unloading port 63 of the transition discharge hopper 6, forming a sealed pipeline. This ensures that there is no leakage of sponge titanium and alloy materials in the inclined elevator and TiO2 in the TiO2 weighing hopper 42 during the unloading process, achieving green and efficient operation and effectively solving the problem of serious dust leakage and pollution of the working environment in traditional methods.

Any variations or modifications to the above embodiments that are within the spirit and essence of the present invention will fall within the scope of the claims of the present invention.
