Description

Technical Field

[0001] This utility model relates to the technical field of metal smelting, and in particular to a metal strip processing and smelting apparatus. Background Technology

[0002] Metal strip is a long strip of sheet material made from metal materials through plastic processing processes such as rolling and drawing. Its thickness and width can be customized according to requirements. It has the characteristics of high dimensional accuracy, good surface quality and uniform mechanical properties. Common materials include aluminum and aluminum alloys, copper and copper alloys, steel, titanium alloys, etc.

[0003] Metal strip processing and smelting is a key step in melting metal raw materials into a uniform melt through high-temperature heating, providing qualified raw materials for subsequent forming processes such as rolling and casting.

[0004] In the existing technology, when processing and smelting metal strips, the surface of the metal strips is often covered with impurities such as moisture and oil, and the shape is mostly long strips or rolls with uneven size. This makes it easy for moisture to vaporize at high temperature and generate bubbles, and for oil to burn and generate harmful residues during the smelting process. At the same time, large strips have small heating areas, slow melting speed and uneven heating, which leads to a decrease in the purity of the melt and the appearance of defects such as pores and inclusions, affecting the processing and smelting efficiency and precision.

[0033] Example 1

[0034] Reference Figures 1 to 4 This is the first embodiment of the present utility model, which provides the following achievable effects:

[0035] Melting unit 100, used for processing and melting metal strip;

[0036] The crushing unit 200 is disposed on the smelting unit 100 and is used to shear and crush the metal strip. The drying unit 300 is disposed on the crushing unit 200 and is used to dry the metal strip by blowing air.

[0037] In use, the air-drying unit 300 first dries the metal strip with air to avoid defects such as porosity and hydrogen embrittlement caused by moisture during subsequent smelting, thus ensuring the purity of the melt. The crushing unit 200 then shears and crushes the dried metal strip to make the metal strip particle size uniform, increase its heating area, effectively improve the efficiency of subsequent smelting, and reduce energy waste. Finally, the metal strip is processed and smelted by the smelting unit 100, thus shortening its pretreatment cycle.

[0038] Example 2

[0039] Reference Figures 1 to 4This is the second embodiment of the present invention, which differs from the previous embodiment in that:

[0040] The smelting unit 100 includes an outer frame 101, a smelting furnace 102 is fixedly installed inside the outer frame 101, a feed pipe 103 is fixedly connected to the smelting furnace 102, one end of the feed pipe 103 is fixedly connected through the outer frame 101, and an exhaust pipe is fixedly connected to the smelting furnace 102.

[0041] The outer frame 101 provides stable protection for the melting furnace 102, ensuring structural stability during high-temperature melting. The feed pipe 103 passes through the outer frame 101 and connects to the furnace body, facilitating the precise delivery of metal strips. The exhaust pipe promptly discharges the melting fumes, preventing gas accumulation in the furnace from affecting the quality of the melt and creating conditions for subsequent waste gas treatment, thereby improving the overall safety and efficiency of melting.

[0042] The smelting furnace 102 heats the metal strip to above its melting point using a specific heating method, transforming it into a molten state. The specific model is GW-300, which is an existing mature technology.

[0043] Specifically, the crushing unit 200 includes a hollow frame 201, which is fixedly installed on the top surface of the outer frame 101. Crushing rollers 202 are rotatably installed on both inner walls of the hollow frame 201. Lateral crushing blocks 203 are fixedly installed on both inner walls of the hollow frame 201. The two lateral crushing blocks 203 cooperate with the crushing rollers 202. A servo motor 204 is fixedly connected to one side surface of the hollow frame 201. The output end of the servo motor 204 is fixedly installed at one end of the crushing rollers 202.

[0044] The servo motor 204 is started, which makes the crushing roller 202 cooperate with the side crushing block 203 to shear and crush the metal strip, increasing the heating area and improving the efficiency of subsequent smelting.

[0045] Specifically, the drying unit 300 includes an extension rod 301, which is fixedly connected to one side surface of the hollow frame 201. One end of the extension rod 301 is fixedly installed to the other end of the crushing roller 202. A fan 302 is fixedly installed on the arm of the extension rod 301. An air collecting hood 303 is fixedly installed on one side surface of the hollow frame 201. A three-way valve 304 is fixedly connected to the air collecting hood 303. Both ends of the three-way valve 304 are fixedly connected to conduits 305. One end of each of the two conduits 305 is fixedly inserted through the hollow frame 201 and fixedly connected to an air outlet frame 306.

[0046] During use, the rotation of the crushing roller 202 causes the extension rod 301 to rotate, which in turn drives the fan 302 to operate by crushing power. The air collecting hood 303 gathers the air and then distributes it through the three-way valve 304 and the duct 305. The air is then evenly blown onto the material through the air outlet frame 306 to dry the metal strip, preventing moisture from being introduced into the smelting process and causing defects. It is also closely connected with the crushing unit 200 to improve the continuity of pretreatment.

[0047] Example 3

[0048] Reference Figures 1 to 4 This is the third embodiment of the present invention, which differs from the previous embodiment in that:

[0049] A temperature sensor 1011 and an infrared gas sensor 1012 are respectively provided on one side surface of the outer frame 101, and the detection ends of the temperature sensor 1011 and the infrared gas sensor 1012 are fixedly inserted through the outer frame 101.

[0050] Temperature sensor 1011 and infrared gas sensor 1012 are directly connected through the outer frame 101, which can monitor the furnace temperature and exhaust gas composition in real time and control the melting state in a timely manner, ensuring stable melt quality, while ensuring compliance of exhaust gas emissions, and improving production safety and controllability.

[0051] Temperature sensor 1011 monitors the temperature change in the melting zone in real time. It converts the physical quantity of temperature into a measurable electrical signal through a temperature sensing element and transmits it to the device control system. The control system then compares this signal with the set melting process temperature and dynamically adjusts the power of the heating components to ensure that the strip is always in a stable molten state. This avoids overheating and accelerated oxidation due to excessive temperature, or insufficient melting and subsequent processing defects due to insufficient temperature. The specific model is WRN-130K thermocouple, which is a mature existing technology.

[0052] The infrared gas sensor 1012 works by utilizing the selective absorption characteristics of gas molecules on infrared light of a specific wavelength. During the smelting process, metal oxidation and fuel combustion produce harmful gases. The sensor emits infrared light of a specific wavelength that passes through the gas-containing environment. By detecting the attenuation of light intensity, the gas concentration is calculated and the signal is transmitted to the control system in real time. The specific model is MH-Z19B, which is an existing mature technology.

[0053] Specifically, a transfer box 1013 is fixedly installed on one side surface of the outer frame 101, a filter plate 1014 is slidably installed on the transfer box 1013, the transfer box 1013 is connected to the outer frame 101, a fan 1015 is fixedly connected to the transfer box 1013, and the fan 1015 is fixedly installed on one side surface of the outer frame 101.

[0054] The transfer box 1013 connects to the outer frame 101 and, together with the fan 1015, can efficiently extract smelting flue gas. The sliding filter plate 1014 is easy to clean and replace, ensuring the filtration effect and effectively purifying the exhaust gas and reducing pollution.

[0055] Specifically, a baffle 1016 is rotatably installed on the transfer box 1013, and the baffle 1016 is in contact with the filter plate 1014.

[0056] The baffle 1016 rotates to fit the filter plate 1014, which can stabilize the filter plate 1014 and prevent it from loosening, ensure the sealing of the filter, prevent flue gas leakage, and make it easy to rotate, which facilitates the maintenance and replacement of the filter plate 1014.

[0057] Specifically, a stabilizing plate 1017 is fixedly installed on the bottom surface of the outer frame 101, and the bottom surface of the stabilizing plate 1017 is set as an anti-slip surface.

[0058] When in use, the stabilizing plate 1017 increases the force-bearing area between the outer frame 101 and the ground, improving overall stability and effectively preventing the device from shifting due to vibration during operation, thus ensuring the safe and stable operation of processes such as smelting.

[0059] During use, the metal strip to be processed first enters the hollow frame 201. The servo motor 204 drives the crushing roller 202 to rotate, which, together with the side crushing blocks 203 on both sides, shears and crushes the strip. At the same time, the extension rod 301 rotates with the crushing roller 202, driving the fan 302 to generate airflow. The airflow is then transported to the side air outlet frames 306 through the air collector 303, the three-way valve 304, and the duct 305 to dry the strip during the crushing process. The pre-treated material enters the smelting furnace 102 inside the outer frame 101 through the feed pipe 103 for smelting. During smelting, the temperature sensor 1011 monitors the temperature inside the furnace in real time, and the infrared gas sensor 1012 detects the composition of the exhaust gas. The generated flue gas is drawn by the fan 1015 and discharged after being filtered by the filter plate 1014.

[0060] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and many of the electrical components in this device are based on existing mature technologies, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
