Description

Technical Field

[0002] The sintering process is to heat the powder raw materials first, and then cool them in a certain way and speed to make the powder particles bond with each other, thereby improving the sintering strength to obtain the desired product.

[0003] During the sintering process, taking the traditional belt sintering machine as an example, the conveyor belt transports the sintered powder outwards. At the same time, the infrared thermal imaging equipment installed in the fire viewing bin at the rear of the machine conducts infrared observation of the transported sintered products to observe the temperature distribution of the sintering surface, so as to judge whether the products are qualified. However, the sintered products lie on the conveyor belt, and after transportation, only the temperature distribution of the sintering connection surface can be observed. The infrared thermal imaging equipment cannot penetrate the entire product, so it is difficult to observe the sintering connection surface at the bottom. Therefore, the collected image data is limited, and the accuracy of judging the product quality is limited. In view of this, this application document proposes a fire viewing monitoring device for industrial metallurgical sintering processes. Summary of the invention

[0022] Reference Figure 1-4 A fire monitoring device for an industrial metallurgical sintering process comprises a fire watching bin 1, a monitoring groove 2 is provided on the inner wall of the fire watching bin 1, an infrared thermal imaging device 3 is provided in the monitoring groove 2, and the characteristic is that a guide groove 8 is provided on the inner wall of the fire watching bin 1, a reciprocating screw 9 is rotatably connected in the guide groove 8, a steering plate 22 is threadedly connected on the reciprocating screw 9, a groove is provided on the side wall of the steering plate 22, a servo motor 23 is installed in the groove, and the output shaft of the servo motor 23 is fixedly connected to a support plate 7, specifically, the steering plate 22 can be rotatably connected to the support plate 7 through supporting bearings and other components, so that the steering plate 22 can provide supporting force to the support plate 7, thereby preventing the output shaft of the servo motor from being broken by the up and down shear forces.

[0023] The side wall of the support plate 7 is provided with a collection groove 19, and the side wall of the support plate 7 is provided with two receiving grooves 20, and the length of the receiving groove 20 is greater than the length of the collection groove 19. It should be noted that, referring to Figure 1 and Figure 3The aggregate trough 19 is a hole-shaped trough with inner walls all around and electrified up and down.

[0024] Each receiving groove 20 is slidably connected with a baffle 18, and the baffle 18 is connected to the inner wall of the receiving groove 20 through a conductive spring 21. Specifically, after the conductive spring 21 is fully extended and the baffle 18 is completely pushed into the collecting groove 19, the side wall of the baffle 18 fits tightly with the inner wall of the collecting groove 19, thereby preventing the sintered products that fall into the collecting groove 19 from falling.

[0025] A driving device for driving the reciprocating screw 9 to rotate is installed on the fire watching bin 1, and a feeding pipe 4 is provided on the fire watching bin 1. Two conical grooves 10 are opened at the bottom of the fire watching bin 1, a return pipe 5 is provided at the bottom of one conical groove 10, and a discharge pipe 6 is provided at the bottom of the other conical groove 10.

[0026] The driving device includes two synchronous pulleys 16 rotating on the upper end of the fire-watching bin 1, and the two synchronous pulleys 16 are connected by synchronous belt transmission. A magnetostrictive rod 26 is rotatably provided in the fire-watching bin 1, and the magnetostrictive rod 26 is connected to the reciprocating screw 9 through a transmission mechanism. The transmission mechanism includes two bevel gears. A transmission groove 27 is opened on the inner wall of the fire-watching bin 1, and the two bevel gears are rotatably connected to the inner top and inner wall of the transmission groove 27, respectively. The reciprocating screw 9 and the magnetostrictive rod 26 are fixedly connected to adjacent bevel gears, respectively.

[0027] A dust suction groove 11 is provided on the side wall of the fire-watching room 1, and an exhaust fan 14 is provided in the dust suction groove 11, wherein one synchronous pulley 16 is fixedly connected to the rotating shaft of the exhaust fan 14 through a connecting rod, and another synchronous pulley 16 is coaxially fixedly connected to a transmission shaft 17, and a driving groove 24 is provided on the side wall of the transmission shaft 17, and the driving groove 24 is a square groove, and the magnetostrictive rod 26 is a square rod, and the magnetostrictive rod 26 is sleeved in the driving groove 24, and a spiral coil 25 is embedded on the inner wall of the driving groove 24. It should be noted that the magnetostrictive rod 26 is made of a ferromagnetostrictive material whose size can change significantly, and can expand and contract along the direction of the magnetic field after the spiral coil 25 is energized to generate a magnetic field, so that the magnetostrictive rod 26 can enter or leave the driving groove 24.

[0028] The dust collecting groove 11 is connected to the interior of the fire watching chamber 1 through two suction pipes 12, and the suction pipes 12 are arranged on the inner walls of both sides of the monitoring groove 2, the air inlet end of the suction pipe 12 is in a blocked state, and the side wall of the suction pipe 12 is provided with a plurality of air inlet holes 13, and the plurality of air inlet holes 13 are evenly distributed around the suction pipe 12. An air outlet pipe 15 is arranged on the inner wall of the dust collecting groove 11. Furthermore, a negative pressure airflow can be generated by an exhaust fan 14 to suck away and discharge the smoke and dust near the monitoring groove 2, to prevent a large number of solids from accumulating in the smoke and dust, thereby hindering the propagation of infrared radiation, and improving the accuracy of the infrared thermal imaging device 3 in observing the sintered products.

[0029] During the use of the device, the raw materials for sintered products will be input through the feed pipe 4, and at the same time, the exhaust fan 14 will be started, and the spiral coil 25 will be energized to generate a magnetic field, then the magnetostrictive rod 26 will be extended under the action of the magnetic field and enter the driving groove 24, then the exhaust fan 14 can drive the transmission shaft 17 to rotate through the two synchronous pulleys 16, and at this time, since the magnetostrictive rod 26 enters the driving groove 24, and the driving groove 24 and the magnetostrictive rod 26 are both square structures, the transmission shaft 17 will drive the magnetostrictive rod 26 to rotate, and drive the reciprocating screw 9 to rotate under the action of the transmission mechanism, so that the steering plate 22 can be pushed to move horizontally and the support plate 7 on its side wall can be driven to move synchronously.

[0030] When the collecting groove 19 on one side of the support plate 7 moves to the bottom of the feeding pipe 4, the spiral coil 25 is immediately fed with a reverse current to generate a reverse magnetic field, and the magnetostrictive rod 26 will shrink and withdraw from the driving groove 24, and the magnetostrictive rod 26, the transmission mechanism and the reciprocating screw 9 will stop rotating. At the same time, the conductive spring 21 in the receiving groove 20 above the support plate 7 is energized and shrinks, and the upper baffle 18 is pulled into the receiving groove 20, and the conductive spring 21 in the lower receiving groove 20 is powered off. After the conductive spring 21 is powered off, it naturally stretches and pushes out the lower baffle 18. At this time, the valve in the feeding pipe 4 is opened again, and the sintered products input by the feeding pipe 4 will fall into the collecting groove 19. After the input, the valve in the feeding pipe 4 is closed, and the spiral coil 25 is closed again. A forward current is passed through the magnetostrictive rod 26 to extend and enter the driving groove 24. At this time, the magnetostrictive rod 26, the transmission mechanism and the reciprocating screw 9 can rotate, and continue to push the steering plate 22 and the support plate 7 to move horizontally, so that the collection tank 19 full of sintered products can be transported to the bottom of the infrared thermal imaging device 3. At this time, the spiral coil 25 is passed through a reverse current to stop the support plate 7 from moving. Then, the upper infrared thermal imaging device 3 can observe the temperature distribution of the sintered connection surface on the front side of the sintered product in the lower collection tank 19. After the observation is completed, the spiral coil 25 is passed through a forward current, and the support plate 7 can be gradually moved back. At the same time, the conductive spring 21 in the upper receiving groove 20 is de-energized and extended, so that the upper baffle 18 can be extended.

[0031] At this time, the servo motor 23 can be operated to drive the support plate 7 to rotate 180 degrees and turn over. After turning over, the support plate 7 can be gradually transported to the bottom of the infrared thermal imaging device 3 again through the reciprocating screw 9 and the steering plate 22. Since the support plate 7 has been turned over after rotating 180 degrees, the upper conductive spring 21 can be energized and contracted again, and the baffle 18 can be pulled into the upper storage groove 20. The infrared thermal imaging device 3 can observe the temperature distribution of the sintered connection surface on the back of the sintered product after turning over. In this way, the sintered connection surfaces on the front and back sides of the sintered product can be observed, thereby increasing the amount of image data collected and improving the accuracy of product quality judgment.

[0032] After the accuracy of the product is judged, if the product is qualified, the collecting trough 19 of the support plate 7 is partially transported to the top of the discharge pipe 6, and then the conductive spring 21 below is energized to shrink and pull the baffle 18 into the receiving trough 20, so that the sintered products in the collecting trough 19 can be discharged through the discharge pipe 6, and the qualified products can be output through conveying equipment such as conveyor belts; if the product is unqualified, the collecting trough 19 of the support plate 7 is partially transported to the top of the return pipe 5, and the baffle 18 below is also collected back into the receiving trough 20, so that the sintered products are recovered to the sintering machine through the return pipe 5 for re-manufacturing, which can also avoid waste.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
