Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy processing, in particular to an annealing treatment device for aluminum alloy strips. Background Art

[0002] Annealing is a metal heat treatment process that heats the aluminum alloy strip to a certain temperature, holds it for a period of time, and then cools it at an appropriate rate to achieve the purpose of improving the mechanical properties of the aluminum alloy strip, reducing hardness, increasing plasticity, and eliminating residual stress. The aluminum alloy strip to be treated is placed on the conveyor in the annealing furnace. The annealing furnace raises the temperature in the furnace to the predetermined annealing temperature through the heating element, so that the aluminum alloy strip is heated evenly. After the set holding time is reached, the heating is stopped, and the temperature in the furnace is lowered through the cooling system, so that the aluminum alloy strip is gradually cooled to room temperature.

[0003] In combination with the above content, it should be explained that: during the annealing process of the conventional aluminum alloy strip crude product, the uneven distribution of the heating elements and the poor air circulation in the furnace may lead to temperature differences in different areas, resulting in inconsistent annealing degrees in different parts of the aluminum alloy strip, affecting product quality; at the same time, due to the defects in the sealing structure design of the inlet and outlet ports of the annealing device, the heat loss inside the annealing device is serious, which easily causes temperature imbalance in the area near the inlet and outlet ports of the annealing device, thereby affecting the annealing effect of the aluminum alloy strip;

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1: This embodiment is used to solve the problem that during the annealing treatment of conventional aluminum alloy crude strips, the uneven distribution of heating elements and the poor air circulation in the furnace may lead to temperature differences in different areas, resulting in inconsistent annealing degrees in different parts of the aluminum alloy strip, affecting product quality; at the same time, due to defects in the sealing structure design of the inlet and outlet ports of the annealing device, the heat loss inside the annealing device is serious, which easily causes temperature imbalance in the area near the inlet and outlet ports of the annealing device, thereby affecting the annealing effect of the aluminum alloy strip.

[0033] See also Figure 1 - Fig. 9 As shown, this embodiment is an annealing treatment device for aluminum alloy strips, including a sealing frame 1, a guide roller 104 is arranged in the middle of the sealing frame 1, and a control panel 2 is arranged on the outer wall of the sealing frame 1, a sealing cylinder 3 is arranged on the end face of the sealing frame 1, and a ring frame 301 is arranged on the end face of the sealing cylinder 3, an air collecting hood 304 is arranged on the inner wall of the ring frame 301, and a scraper 305 is arranged on the outer wall of the air collecting hood 304, a slag discharge mechanism 6 is arranged at the bottom of the sealing cylinder 3, and an auxiliary heating mechanism 4 is arranged in the center of the sealing cylinder 3; the slag discharge mechanism 6 includes a U-shaped frame 601 and a slag collecting cylinder 605, and a rotating paddle 606 is arranged inside the slag collecting cylinder 605, and the auxiliary heating mechanism 4 includes a supporting frame 401 and a pushing cylinder 402, a guide plate 405 and a heat return hood 403 are arranged on the supporting frame 401, and a heater 5 is arranged at the bottom of the pushing cylinder 402;

[0034] The control panel 2 is internally provided with a processor, a data acquisition module, a data analysis module and a signal execution module; the data acquisition module is used to collect the local residual fluctuation value RCz located on the sealing frame 1 and the slag aggregation value ZLz located on the slag discharge mechanism 6 during the use of the annealing device, and send the local residual fluctuation value RCz and the slag aggregation value ZLz to the data analysis module via the processor; 90 minutes during the use of the annealing device is set as the time threshold;

[0035] It should be noted that: the local residual fluctuation value RCz is expressed as the average value of the maximum and minimum temperature residual differences in the local area of ​​the surface of the aluminum alloy strip that has passed through the annealing device within the time threshold, and the value of the local residual fluctuation value RCz reflects whether the surface temperature distribution of the material processed by the annealing device of the aluminum alloy strip within the time threshold is uniform, and the larger the value of the local residual fluctuation value RCz, the greater the temperature difference fluctuation of the strip surface in this area during the annealing treatment within the time threshold, and the slag aggregation value ZLz is expressed as the amount of impurities generated by the annealing treatment of the aluminum alloy strip that enter the slag collecting barrel 605 within the time threshold. In addition, the local residual fluctuation value RCz is collected by the temperature sensor installed in the outlet area of ​​the sealing frame 1, and the slag aggregation value ZLz is collected by the particle scanning sensor installed inside the slag collecting barrel 605;

[0036] After receiving the local residual fluctuation value RCz and the slag aggregation value ZLz, the data analysis module immediately analyzes the processing risk of the annealing device. The specific analysis process is as follows:

[0037] The local residual fluctuation value RCz and slag aggregation value ZLz of the annealing device within the time threshold are obtained, and the formula The processing risk coefficient Gi is obtained, where a and b are respectively the proportional coefficients of the local residual fluctuation value RCz and the slag aggregation value ZLz, a>b>0, Gi is represented as the processing risk coefficient, and the preset processing risk coefficient Yi stored in the processor is retrieved for comparison and analysis with the processing risk coefficient Gi;

[0038] If the processing risk coefficient Gi≥the preset processing risk coefficient Yi, it is determined that there is an abnormal risk in the use of the annealing device within the time threshold, and a control signal is generated. The generated signal is sent to the signal execution module through the processor. After receiving the control signal, the signal execution module immediately controls the push cylinder 402 to work;

[0039] The airflow entering the air collecting hood 406 is guided along the internal pipeline of the air collecting hood 406, and the hot air is diverted to the jet rack 404. The jet rack 404 is actively pulled close to the heater 5 by the supporting frame 401 and the lower cylinder body of the pushing cylinder 402, and the hot air is blown from the outside to the inside toward the aluminum alloy strip. The air flows through the heater 5, and the heat retained on the surface of the heater 5 is carried away and conducted to the aluminum alloy strip, and the collected high-temperature air is caused to flow quickly in the envelope 3, which effectively ensures that the temperature difference of each area inside the entire envelope 3 is low to a controllable range, which is conducive to the heating effect of the movement of the aluminum alloy strip in the envelope 3;

[0040] A fine-tuning cylinder is provided at the top of the air passage 407, and the fine-tuning cylinder drives the air push block 408 to slide along the inside of the air passage 407. During the sliding of the air push block 408, the traction connecting rod 409 moves up and down in the air passage 407, and the connecting rod 409 drives the rotating kit 410 to deflect, and the connecting rod 409 is a telescopic structure, which is composed of two groups of rod sections. The rotating kit 410 drives the guide vane 405 to deflect at a fixed angle, thereby changing the direction of the airflow ejected from the jet frame 404, so as to make the high-temperature hot air from the heater 5 to be evenly dispersed and conducted to the aluminum alloy strip, and avoid local direct blowing, which causes partial temperature abnormality;

[0041] If the processing risk coefficient Gi is less than the preset processing risk coefficient Yi, no signal is generated.

[0042] Embodiment 2: This embodiment is an annealing treatment device for aluminum alloy strips. The aluminum alloy strips are pulled through the annealing device by external equipment. The aluminum alloy strips pass through the sealing drum 3 from the sealing frame 1 at the inlet end and move out along the middle of the sealing frame 1 at the outlet end. The heater 5 performs high-temperature heat treatment on the aluminum alloy strips passing through.

[0043] A driving cylinder 101 is embedded on the inner wall of the top and bottom of the sealing frame 1, and a limiting plate 102 located between multiple groups of driving cylinders 101 is arranged in the middle of the sealing frame 1, and a sealing cover 105 is slidably sleeved on the outer wall of the limiting plate 102. The top and bottom of the side of the sealing cover 105 are both provided with an axis frame 106 connected to the guide roller 104, and the top and bottom of the sealing cover 105 are both provided with a slider 103. When the aluminum alloy strip passes through the sealing frame 1, the driving cylinder 101 drives the sealing cover 105 to slide along the surface of the limiting plate 102 through the slider 103, and the sealing cover 105 passes through the axis frame 106. The guide rollers 104 are driven to lean against each other until they abut against the surface of the aluminum alloy strip. At this time, the guide rollers 104 abut and clamp the surfaces of both sides of the aluminum alloy strip, and cooperate with the external dragging and traction of the aluminum alloy strip to cause the aluminum alloy strip to be stretched and straightened into the sealing tube 3. The aluminum alloy strip is clamped and contacted by the guide rollers 104, which causes some impurities that are easy to fall off on the surface of the aluminum alloy strip just produced to fall off, and the guide rollers 104, the sealing cover 105 and the limit plate 102 are used to form a telescopic sealing structure in the inlet and outlet areas of the sealing frame 1, which effectively reduces the leakage of high-temperature hot air inside the sealing tube 3.

[0044] The outer side of the end surface of the ring frame 301 is concavely provided with a special-shaped guide groove 302, and the inner side of the end surface of the ring frame 301 is provided with an annular guide rail 303, the top of the outer wall of the air collecting hood 304 is provided with a scraper 305, and the bottom of the outer wall of the air collecting hood 304 is provided with a slag collecting bucket 306, the end surface of the air collecting hood 304 is provided with a rotating fastener 307 connected to the annular guide rail 303, the side of the rotating fastener 307 is provided with a sliding fastener 308, and the cross section of the sliding fastener 308 is provided with a guide column 309 connected to the special-shaped guide groove 302;

[0045] When the aluminum alloy strip enters the sealing cylinder 3, the outer shell of the push cylinder 402 is connected and fixed to the inner end surface of the ring frame 301, and the push cylinder 402 is composed of two sets of upper and lower cylinder bodies. The upper cylinder body drives the heater 5 to move through the crossbeam 501, so that the heaters 5 are close to the aluminum alloy strip, so as to achieve close-range high-temperature heat conduction treatment of the double-sided outer wall area of ​​the aluminum alloy strip, and effectively reduce heat conduction loss;

[0046] The lower cylinder drives the support frame 401 to coaxially approach the heater 5, so that the heat return cover 403 is close to each other, forming a small semicircular covering structure around the heater 5, and the heat resistance material on the surface of the heat return cover 403 is combined to reduce the heat generated by the heater 5.

[0047] The ring frame 301 drives multiple groups of air collecting hoods 304 to rotate continuously on the outer side of the inner wall of the sealing tube 3 through the annular guide rail 303. The air collecting hood 304 maintains a rotational connection and traction drag with the annular guide rail 303 through the rotating fastener 307. One end of the guide column 309 body is partially inserted into the inside of the special-shaped guide groove 302 and maintains limited movable contact with it. The other end of the guide column 309 is sleeved and inserted into the side center of the sliding fastener 308. The sliding fastener 308 and the rotating fastener 307 are composed of multiple groups of discs that can be rotatably connected together. The sliding fastener 308 and the cross-sections on both sides of the air collecting hood 304 are sleeved and slid. The special-shaped guide groove 302 drives the guide column 309 and the sliding fastener 308 to drive the air collecting hood 304 to deflect with the rotating fastener 307 as the central axis, so that the scraper 305 contacts the inner wall of the sealing tube 3, and the impurities attached to the inner wall of the sealing tube 3 by the hot gas are cleaned, and the cleaned impurities fall into the slag collecting bucket 306 along the outer wall of the air collecting hood 304.

[0048] As the air collecting hood 304 rotates, the arc-shaped cavity at the bottom of the air collecting hood 304 pushes the high-temperature hot air collected at the top of the envelope 3 to flow to the bottom of the envelope 3. When the air collecting hood 304 moves in a circular trajectory along the inside of the envelope 3 and passes over the bottom of the envelope 3, the opening of the slag collecting bucket 306 gradually deflects downward, causing the impurities collected in the slag collecting bucket 306 to fall. For example, when the slag collecting bucket 306 rotates counterclockwise, the slag discharge mechanism 6 is located at the six o'clock direction, and the top opening of the slag discharge mechanism 6 covers the seven to five o'clock positions. Direction range: when the slag collecting bucket 306 approaches the five o'clock direction, the track of the groove of the special-shaped guide groove 302 changes, causing the distance between the rotating fastener 307 and the sliding fastener 308 to change, accelerating the adjustment of the air collecting hood 304 to deflect with the rotating fastener 307 as the central axis, so that when the air collecting hood 304 approaches the five o'clock direction from the seven o'clock direction, the opening of the slag collecting bucket 306 gradually changes from a horizontal state to a state of slightly tilting upwards → horizontal → tilting downwards, and the impurities collected inside are dumped into the slag discharge mechanism 6;

[0049] The top of both sides of the U-shaped frame 601 are symmetrically provided with air injection slots 603, the bottom center of the U-shaped frame 601 is provided with an air diffuser arc cover 604 connected to the air suction grille 602, and an exhaust fan is provided inside the air diffuser arc cover 604, a notch connected to the outer bottom of the air diffuser arc cover 604 is provided at the top of the slag collecting barrel 605, and an electric gate 607 is provided at the bottom of the slag collecting barrel 605, and a driving motor connected to the rotating blade 606 is provided on the outer wall of the end surface of the slag collecting barrel 605;

[0050] The exhaust fan inside the diffuser arc hood 604 is in continuous operation, and the hot air drawn by the air collecting hood 304 is extracted through the air suction grille 602, and the impurities contained in the hot air are intercepted and separated through the air suction grille 602, so that the hot air enters the diffuser arc hood 604 along the air suction grille 602, and is diverted by the exhaust fan through the regulating valve. Part of the hot air is continuously sprayed toward the heater 5 along the upward micro-holes provided on the surface of the diffuser arc hood 604, and part of the hot air is sprayed upward along the air injection slot 603 into the air collecting hood 406, and an air wall structure is formed on the top of both sides of the U-shaped frame 601, so as to promote the reflux of hot air, reduce the continuous heating energy consumption, and promote the heat flow inside the sealing tube 3, and avoid the heat unevenness such as local high temperature. The separated impurities, under the suction and traction of the air suction grille 602, adhere to the surface of the air suction grille 602 and fall into the gap, and then enter the slag collecting tube 605 through the gap;

[0051] An air duct 407 is arranged in the inner wall of the support frame 401, and air push blocks 408 are arranged at the top and bottom of the air duct 407, connecting rods 409 are arranged between the air push blocks 408, and a rotating kit 410 connected to the guide vane 405 is sleeved on the surface of the connecting rod 409, an air collecting hood 406 is arranged on the outer wall of the bottom of the heat return cover 403, an injection frame 404 close to the guide vane 405 is arranged on the inner wall section of the support frame 401, and a crossbeam 501 connected to the pushing cylinder 402 is arranged at the top and bottom of the heater 5; the driving motor drives the rotating blade 606 to deflect slowly and regularly, so that impurities falling into the rotating blade 606 along the notch are caused to fall and transfer when the rotating blade 606 deflects until it approaches the electric gate 607 area, and the electric gate 607 is opened regularly to discharge a small amount of hot air and impurities together.

[0052] Combining the first embodiment and the second embodiment, it is possible to realize the process of system data analysis and mechanical structure linkage operation, which is helpful to evenly distribute the heat inside the envelope 3 and ensure the annealing heat treatment effect of the aluminum alloy strip, and can also actively pull the high-temperature concentration generated by the heat treatment and actively scrape the inside of the envelope 3, thereby reducing the impact of impurity adhesion on the thermal insulation environment of the device body, and the uneven temperature of high-temperature heat accumulation and retention, thereby improving the heat treatment efficiency of the aluminum alloy strip.
