Description

Technical Field

[0001] This invention relates to the field of metering and packaging technology, specifically to a fully automatic metering and packaging device for vanadium-nitrogen alloys. Background Technology

[0002] Vanadium nitride, also known as vanadium-nitrogen alloy, is a new type of alloying additive that can replace ferrovanadium in the production of microalloyed steel. When added to steel, vanadium nitride can improve the comprehensive mechanical properties of steel, such as strength, toughness, ductility, and resistance to thermal fatigue, and also give the steel good weldability. When applied to high-strength low-alloy steel, vanadium-nitrogen alloy can simultaneously and effectively perform vanadium and nitrogen microalloying, promote the precipitation of carbon, vanadium, and nitrogen compounds in the steel, and more effectively exert the effects of precipitation strengthening and grain refinement.

[0003] Currently, the main production equipment for vanadium-nitrogen alloys includes pusher kilns and medium-frequency furnaces. After production, the vanadium-nitrogen alloy passes through a cooling section within the furnace and is discharged from the machine. The discharged vanadium-nitrogen alloy is typically at room temperature +25–35°C. It then cools naturally to room temperature before entering a metering and packaging machine for final packaging, facilitating storage and transportation. However, with the increasing production of vanadium-nitrogen alloys, the cooling efficiency of the pusher kilns or medium-frequency furnaces decreases, resulting in the produced vanadium-nitrogen alloys carrying a certain amount of heat, sometimes exceeding room temperature by more than 40°C. To reduce the contact between the vanadium-nitrogen alloy and air, it usually needs to be sealed in packaging. If the vanadium-nitrogen alloy is not completely cooled and its temperature is too high, it may scald or deform the packaging bag. After sealing, as the vanadium-nitrogen alloy cools naturally, the surrounding air will generate a certain amount of moisture, which will affect the storage of the vanadium-nitrogen alloy and cause surface deterioration. Furthermore, in existing automatic weighing and packaging machines, the items to be packaged enter through the machine's feed inlet and exit through the discharge outlet onto the packaging bag located on the weighing device. Because the packaging bag itself is relatively soft, when the vanadium-nitrogen alloy enters the bag, the opening of the bag is easily blocked as the alloy falls, causing the alloy to fall outside the bag and resulting in malfunctions in the weighing and packaging machine. Therefore, manual supervision is required during the packaging process, and manual detection and troubleshooting are necessary before packaging can continue, reducing the efficiency of the weighing and packaging machine and increasing production costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a fully automatic metering and packaging device for vanadium-nitrogen alloys, which solves the problems mentioned in the background technology, especially the problems of residual heat damaging packaging bags, deterioration of vanadium-nitrogen alloys during storage, and high packaging production costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic metering and packaging device for vanadium-nitrogen alloys, comprising a box body, a controller mounted on the box body, a feeding box connected to the top of the box body, a fan installed on the right side of the feeding box, the fan being controlled by the controller on the box body, a collection box on the left side of the feeding box, an elastic plate disposed inside the feeding box, a discharge port located in the middle of the box body, the discharge port being connected to the outlet of the feeding box, and an electric valve disposed inside the discharge port, the electric valve being controlled by the controller on the box body, a sealing device located below the discharge port, and a weighing platform mounted at the bottom of the box body.

[0006] Preferably, the torsion spring shaft in the middle of the elastic plate is connected to the inside of the feed box, and the left and right sides of the elastic plate are arc-shaped plates that can move inside the feed box.

[0007] Preferably, the torsion spring of the torsion spring shaft is replaceable.

[0008] Preferably, the collection box is movably inserted into the left side of the feed box, and a dust filter screen is provided on the outside of the collection box.

[0009] Preferably, the sealing device is installed above the weighing platform and is controlled by a controller on the housing. The sealing device consists of an electric slide rail, fixed rods, and side plates. The electric slide rail is fixed to the two side plates. There are two fixed rods, which are vertically and movably connected to the electric slide rail. The fixed rods are heat-generating.

[0010] Preferably, the upper surface of the fixing rod is provided with a fixing post, and the top end of the fixing post is pointed.

[0011] Preferably, the feed box is equipped with an infrared thermometer. Under the control of the controller, the infrared thermometer can be linked with the fan and can feed back the temperature measurement results to the controller. The controller can adjust the air volume of the fan in real time based on the temperature measurement results.

[0012] Preferably, the fan is connected to an inert gas pipeline, and the gas blown out is inert gas with a temperature of 0℃ to room temperature.

[0013] This invention provides a fully automatic metering and packaging device for vanadium-nitrogen alloys, which has the following beneficial effects:

[0014] 1. This fully automatic vanadium-nitrogen alloy metering and packaging device, by installing a fan, collection box, and dust filter at the inlet, further cools the vanadium-nitrogen alloy passing through the inlet box. This prevents the vanadium-nitrogen alloy from carrying residual heat from the furnace and damaging or deforming the packaging bags, and avoids the problem of moisture inside the sealed bags due to premature sealing, thus improving the production and storage quality of the vanadium-nitrogen alloy. Simultaneously, the use of elastic plates extends the residence time of the vanadium-nitrogen alloy in the inlet box, thereby improving the cooling effect and removing dust or vanadium-nitrogen alloy debris from the exterior, improving the packaging quality. An infrared thermometer is installed inside the inlet box. Under the control of the controller, the infrared thermometer can be linked with the fan, providing temperature measurement results. The controller adjusts the fan airflow in real time based on the temperature measurement results, further accelerating the cooling speed of the vanadium-nitrogen alloy and preventing it from entering the packaging process before complete cooling, thus improving packaging quality. Furthermore, the fan is connected to an inert gas pipeline, and the blower sprays out inert gas with a temperature of 0°C to room temperature. This not only accelerates the cooling of the vanadium-nitrogen alloy, but also keeps the vanadium-nitrogen alloy in an inert gas protective environment during cooling, thus avoiding or reducing the oxidation of the vanadium-nitrogen alloy product.

[0015] 2. Considering the differences in residual temperature of vanadium-nitrogen alloy produced in each batch, or the decreasing cooling effect of the preceding equipment due to prolonged use, the required cooling time for vanadium-nitrogen alloy is increasing. The torsion spring shaft features a replaceable torsion spring. Based on the residual temperature of each batch of vanadium-nitrogen alloy, the required cooling time can be calculated, and a torsion spring with the appropriate torque can be used. This adjusts the residence time of the vanadium-nitrogen alloy on the elastic plate, ensuring more precise and complete cooling for packaging, thus improving packaging quality.

[0016] 3. This fully automatic vanadium-nitrogen alloy weighing and packaging device features a sealing device located above the weighing platform at the bottom of the device. This device promptly closes the electric valve inside the discharge port when the weight of the vanadium-nitrogen alloy inside the packaging bag reaches the set value, preventing further material feeding and achieving a timely seal. This prevents external impurities and excess vanadium-nitrogen product from entering the packaging bag and causing contamination or weighing errors. Simultaneously, the fixing column facilitates the securing of the packaging bag, preventing the bag opening from collapsing during the vanadium-nitrogen alloy's descent, thus reducing the failure rate of the weighing and packaging device and improving production efficiency.

[0025] Preferably, the torsion spring shaft in the middle of the elastic plate 4 is connected to the inside of the feed box 2, and the left and right sides of the elastic plate 4 are arc-shaped plates that can move inside the feed box 2.

[0026] Preferably, the torsion spring of the torsion spring shaft is replaceable.

[0027] Preferably, the collection box 5 is movably inserted into the left side of the feed box 2, and a dust filter screen is provided on the outside of the collection box 5.

[0028] Preferably, the sealing device 7 is installed above the weighing platform 9, and the sealing device 7 is controlled by the controller 10 on the box body 1. The sealing device 7 consists of an electric slide rail 11, a fixing rod 12 and a side plate 13. The electric slide rail 11 is fixed on the two side plates 13. There are two fixing rods 12, which are vertically and movably connected to the electric slide rail 12. The fixing rod 12 can be heated.

[0029] Preferably, a fixing post 8 is provided on the upper surface of the fixing rod 12, and the top end of the fixing post 8 is pointed.

[0030] Preferably, the feed box 2 is equipped with an infrared thermometer. The infrared thermometer can be linked with the fan 3 under the control of the controller 10. The infrared thermometer can feed back the temperature measurement result to the controller 10, and the controller 10 can adjust the air volume of the fan 3 in real time based on the temperature measurement result.

[0031] Preferably, the fan (3) is connected to an inert gas pipeline, and the gas blown out is inert gas with a temperature of 0°C to room temperature.

[0032] Example 2

[0033] Please see Figure 1-4This invention provides a technical solution: a fully automatic metering and packaging device for vanadium-nitrogen alloys, comprising a box body 1, a controller 10 on the box body 1, a feeding box 2 connected to the top of the box body 1, a fan 3 installed on the right side of the feeding box 2, the fan 3 being controlled by the controller 10 on the box body 1, a collection box 5 on the left side of the feeding box 2, the collection box 5 being movably inserted into the left side of the feeding box 2 for easy removal and cleaning, an elastic plate 4 installed inside the feeding box 2, the middle of the elastic plate 4 being a torsion spring shaft connected inside the feeding box 2, and the elastic plate 4 being divided into two parts. A discharge port 6 is provided in the middle of the box body 1, the discharge port 6 being connected to the outlet of the feeding box 2, and an electric valve is provided inside the discharge port 6, the electric valve being controlled by the controller on the box body 1, a sealing device 7 being provided below the discharge port 6, and a weighing platform 9 being installed at the bottom of the box body 1. The torsion spring on the torsion spring shaft is replaceable, allowing selection of a suitable torsion spring based on different materials or temperatures. Considering the variations in residual temperature between batches of vanadium-nitrogen alloy produced, or the decreasing cooling efficiency of upstream equipment due to prolonged use, thus requiring longer cooling times for the vanadium-nitrogen alloy, the torsion spring on the shaft is designed to be replaceable. This allows for calculation of the required cooling time based on the residual temperature of each batch of vanadium-nitrogen alloy, enabling the replacement with a torsion spring of appropriate torque. This adjusts the residence time of the vanadium-nitrogen alloy on the elastic plate, ensuring more precise and complete cooling for packaging, thereby improving packaging quality. When the vanadium-nitrogen alloy on the elastic plate 4 exceeds the pressure limit that the torsion spring on the elastic plate 4 can withstand, the vanadium-nitrogen alloy on the elastic plate 4 enters the box 1 through the gap between the elastic plate 4 and the feed box 2 and is discharged from the discharge port 6. Through the action of the fan 3, the vanadium-nitrogen alloy just discharged from the furnace can be further cooled, and water vapor, dust, and other impurities adhering to the surface of the vanadium-nitrogen alloy can be removed, improving the quality of the vanadium-nitrogen alloy packaging. Simultaneously, the buffering effect of the elastic plate 4 prolongs the residence time of the vanadium-nitrogen alloy in the feed box 2, enhancing the efficiency of the airflow generated by the fan 3 in cooling and removing impurities from the vanadium-nitrogen alloy, thus improving the packaging quality of the device. Furthermore, an infrared thermometer can be installed in the feed box 2. Under the control of the controller 10, the infrared thermometer can be linked with the fan, and the infrared thermometer can feed back the temperature measurement results to the controller 10. The controller 10 adjusts the airflow of the fan 3 in real time based on the temperature measurement results. When the infrared thermometer detects that the temperature of the vanadium-nitrogen alloy in the feeding box 2 is too high, the air volume of the fan 3 is increased to further accelerate the cooling speed of the vanadium-nitrogen alloy, thus preventing the vanadium-nitrogen alloy from entering the packaging process before it is completely cooled, thereby improving the quality of the packaging.Furthermore, by connecting the blower 3 to an inert gas pipeline, the blower 3 will spray out inert gas. The temperature of the inert gas is set to 0℃ to room temperature, which can accelerate the cooling of the vanadium-nitrogen alloy and also keep the vanadium-nitrogen alloy in an inert gas protective environment during cooling, thus avoiding or reducing the oxidation of the vanadium-nitrogen alloy product.

[0034] A sealing device 7 is installed below the discharge port 6, above the weighing platform 9. The sealing device 7 is controlled by the controller 10 on the housing 1. The sealing device 7 consists of an electric slide rail 11 and two fixing rods 12. The electric slide rail 11 is fixed to the side plates 13 on both sides. Two fixing rods 12 are vertically and movably connected to the electric slide rail 11, and can move on the electric slide rail 11 on both sides under the control of the controller 10. The fixing rods 12 have a heating function, enabling thermoplastic sealing of the bags. A fixing column 8 is connected to the top of the fixing rod 12, and the top of the fixing column 8 is pointed, allowing the edge of the packaging bag opening to be hooked onto the fixing column 8. This prevents the packaging bag from being crushed by the vanadium-nitrogen alloy discharged from the discharge port 6, improving the working efficiency of the packaging device.

[0035] In summary, this fully automatic vanadium-nitrogen alloy metering and packaging device, when in use, is powered on, set on the controller 10, and the packaging bag is placed below the discharge port 6. Simultaneously, the edges of the packaging bag opening are attached to the fixed posts 8. After starting the device, the vanadium-nitrogen alloy discharged from the previous process furnace is placed into the feed box 2. The vanadium-nitrogen alloy remains on the elastic plate 4. The air generated by the blower 3 further cools and removes impurities from the vanadium-nitrogen alloy. Moisture and dust adhering to the exterior of the vanadium-nitrogen alloy enter the collection box 5 with the airflow. After being filtered by the collection box 5, the airflow is discharged from the outside of the collection box 5. As the vanadium-nitrogen alloy is added, the pressure on the elastic plate 4 gradually increases. When it exceeds the bearing capacity of the elastic plate 4, the sides of the elastic plate 4 tilt downwards. The vanadium-nitrogen alloy on the elastic plate 4 rotates and enters the interior of the box 1 and enters the packaging bag placed below the outlet 6. The packaging bag is on the weighing platform 9 at the bottom of the box 1. The weighing platform 9 monitors the mass of the vanadium-nitrogen alloy in the packaging bag in real time. When the mass of the vanadium-nitrogen alloy reaches the set value, the weighing platform 9 sends information to the controller 10. The controller 10 closes the electric valve inside the outlet 6. Then, under the control of the controller 10, the fixing rod 12 of the sealing device 7 begins to close along the track of the electric slide rail 11, closing and compacting the opening of the packaging bag. At the same time, due to its heating function, the fixing rod 12 of the sealing device 7 heats up, causing the sealing film of the inner layer of the packaging bag to melt and adhere together, completing the fully automatic metering and packaging of the vanadium-nitrogen alloy.
