Description

Technical Field

[0001] The invention relates to the technical field of inoculant processing, in particular to a detection and sorting device for inoculant particles. Background Art

[0002] An inoculant is an additive used in metallurgical processes, particularly in the foundry industry. Its primary function is to refine the microstructure of materials such as cast iron, thereby improving the mechanical properties of the material. By adding an appropriate amount of inoculant to the molten metal, the grain structure of the casting can be effectively controlled, reducing or eliminating certain casting defects, such as white cast and shrinkage cavities. Commonly used inoculants include ferrosilicon and calcium silicon alloys, which contain a high proportion of active elements such as silicon, calcium, and barium. These elements act as nucleating agents in the molten metal, promoting the formation of more nuclei, thereby refining the grains and improving the quality of the casting.

[0003] The correct selection and use of inoculants is crucial for achieving high-quality castings. The application scenarios for different inoculant particle sizes vary due to the thermodynamic requirements of the casting process, equipment compatibility limitations, and defect control objectives. Targeted testing maximizes inoculant performance and reduces process risks. Traditional sorting technologies rely on single screening or laboratory spot checks, which are unable to conduct real-time testing, resulting in delayed sorting and insufficient accuracy.

[0004] Therefore, there is an urgent need for a detection and sorting device for inoculant particles to achieve accurate sorting from the source, reduce the defect rate and improve resource utilization, and fill the technical gap in the industry. Summary of the Invention

An electric heater 6 is installed on the inner wall of the unloading platform 5 away from the output port to dry the inoculant particles and reduce the impact of moisture on particle detection. A dust collector 7 is provided above the unloading platform 5 to absorb dust carried by the inoculant particles themselves to prevent dust from affecting the subsequent detection accuracy.

[0041] Furthermore, connecting ends 52 are fixedly connected to the outer walls of both sides of the unloading platform 5, and the connecting ends 52 are connected to the driving part 1 with bearings, and the output end of the driving part 1 is fixedly connected to the pneumatic support rod 10, and the outer side of the dust collector 7 is fixedly connected to the positioning ring 8, and the two sides of the positioning ring 8 are welded with cross bars 9, and the other end of the cross bar 9 is connected to the driving part 2 with bearings, and the output end of the driving part 2 is hinged to the movable rod end of the pneumatic support rod 10, so that when the pneumatic support rod 10 rotates around the connecting end 52, the dust collector 7 rotates freely around the movable end of the pneumatic support rod 10, thereby achieving a multi-angle dust removal effect of the dust collector 7;

[0042] A hopper 12 is riveted above the bracket 4. An intelligent electric control valve is installed at the discharge port of the hopper 12. The intelligent electric control valve is integrated with a gravity flow meter, which can control the flow rate of particles passing through the discharge port and measure the flow rate, providing real-time feedback on the output particle quantity.

[0043] A first conveyor belt 13 is provided below the hopper 12 and is installed inside the first frame 1. The first conveyor belt 13 has a structure with conveyor belts on both sides and a filter screen in the middle conveying area, and the aperture of the filter screen only allows small particles of inoculant to pass through. A motor 1 is installed on the side of the first frame 1 close to the bracket 4. A number of rollers are connected to the bearings above the two sides of the first frame 1. The conveyor belt is tensioned on the rollers, and the outer ends of the rollers are fixedly connected to pulleys. The same pulley is installed on the output shaft of the motor 1, and a belt is provided on the outside of the pulley, so that the first conveyor belt 13 can transport the particles through the motor 1.

[0044] The middle of the two sides of the material rack 3 is fixedly connected with a side plate 14 to prevent the particles from flying out. Figure 4 、 Figure 5 , the inner sides of the two side plates 14 are welded with support plates 15, the lower side of the support plates 15 is fixedly connected with a guide rod 16, and the guide rod 16 is slidably connected with a mounting box 17, reference Figure 6, the bottom surface of the mounting box 17 is connected to a number of rotating rods 18 by bearings, the upper ends of the rotating rods 18 are located inside the mounting box 17 and are fixedly connected to a number of gears 19, and the gears 19 are all meshed. A worm 20 is provided adjacent to one side of the rotating rod 18. The worm 20 is connected to the bottom surface of the mounting box 17 by bearings, and the upper end of the worm 20 is located inside the mounting box 17 and is fixedly connected to the gear 19. A stop frame 21 is installed on the rod body of the worm 20, and the stop frame 21 is "L" shaped , a positioning block 22 is welded on the top of the vertical frame of the "L"-shaped frame on the stop frame 21, and a tapered roller 23 is connected to the positioning block 22 through a rod bearing. The tapered roller 23 is engaged with the gear teeth of the worm 20, so that the rotation and displacement of the worm 20 can be driven by the rotation of the tapered roller 23. After the worm 20 rotates, the rotating rod 18 is rotated synchronously through the transmission of the gear 19. After the worm 20 is displaced, it drives the installation box 17 to slide on the guide rod 16, thereby causing the rotating rod 18 to displace;

[0045] The bottom ends of the rotating rods 18 and the worm 20 are fixedly connected with blades 24. Figure 4 The end of the rod on one side of the tapered roller 23 is fixedly connected to a rotating motor through a coupling. The rotating motor is installed on the side plate 14, so that after the rotating motor drives, several blades 24 rotate and move back and forth up and down. Two groups of blades 24 are provided above the first conveyor belt 13. When the particles are transported to the bottom of the blades 24, the blades 24 continuously rotate and move back and forth up and down, so that some small particles of the agglomerated inoculant are broken up by force, thereby improving the accuracy of the inoculant particle detection.

[0046] refer to Figure 4 、 Figure 7 , first guard plates 25 are installed on both sides of the first conveyor belt 13, and support frames 26 are welded on the two frames of the material platform 3 near the output end of the first conveyor belt 13, and an electric slide rail is installed inside the support frame 26, and a slider 27 is slidably connected inside the electric slide rail. The other end of the slider 27 is provided with a slide groove 28, and a micro linear motor is installed in the slide groove 28. A roller brush 29 is fixedly connected to the sliding end of the micro linear motor, and a perforation corresponding to the roller brush 29 is provided on the first guard plate 25. When the electric slide rail is started and the roller brush 29 is driven to move, the roller brush 29 passes through the perforation on the first guard plate 25 into the inside of the first conveyor belt 13 and contacts the filter screen of the first conveyor belt 13, thereby cleaning the filter screen of the first conveyor belt 13. At this time, the bristles of the roller brush 29 are evenly stressed on the filter screens on both sides of the roller brush 29. When the linear motor is started, the roller brush 29 moves upward or downward for a distance. At this time, the roller brush 29 will achieve close contact with the upper inner side or lower inner side of the filter screen of the first conveyor belt 13, which will further carry out targeted cleaning of the filter screen;

[0047] It should be noted that a group of blades 24 close to the first conveyor belt 13 is located directly above the roller brush 29 .

[0048] refer to Figure 1-4 A first receiving plate 30 is installed between the two first guard plates 25, and the first receiving plate 30 is riveted to the inner side of the first guard plate 25, thereby realizing the transfer of particles. A first trough 31 is provided below the first conveyor belt 13 for collecting the smallest particle inoculant passing through the filter screen of the first conveyor belt 13. A first weighing sensor is installed at the bottom of the first trough 31 for detecting the weight of the small particles in the first trough 31.

[0049] refer to Figure 8 The second conveyor belt 32 is installed above the second frame 2, and one end of the second conveyor belt 32 close to the first receiving plate 30 is the input end, and the other end is the output end. The structure and driving mode of the second conveyor belt 32 are the same as those of the first conveyor belt 13. The filter mesh aperture of the second conveyor belt 32 allows the inoculant of medium particles to pass through. Second guard plates 33 are installed on both sides of the second conveyor belt 32, and the second guard plates 33 are fixedly connected to the top of the second frame 2. The outer side of the second guard plate 33 is welded with the same support frame 26, and the inside of the support frame 26 is installed with the same electric slide rail, and the inside of the electric slide rail is slidably connected with the same slider 27, and the other end of the slider 27 is provided with the same slide groove 28, and the same micro linear motor is installed in the slide groove 28. The sliding end of the micro linear motor is fixedly connected with the same roller brush 29, and the second guard plate 33 is provided with a perforation, so as to achieve the same cleaning effect of the roller brush 29 on the filter mesh of the second conveyor belt 32;

[0050] A second receiving plate 38 is installed between the two second guard plates 33, and the second receiving plate 38 is riveted to the inner side of the second guard plate 33, so as to realize further transportation of the particles. A second trough 39 is provided below the second conveyor belt 32 for collecting the medium-particle inoculant passing through the filter screen of the second conveyor belt 32. A second weighing sensor is installed at the bottom of the second trough 39 for detecting the weight of the medium-particles in the second trough 39.

[0051] refer to Figure 1 A third trough 40 is provided below the second receiving plate 38 for collecting large particles of inoculant. A third weighing sensor is installed at the bottom of the third trough 40 for detecting the weight of the large particles in the third trough 40.

[0052] refer to Figure 3 A camera 11 is fixedly connected to one side of the unloading platform 5 for monitoring the detection process of the inoculant particles on the conveyor belt. An electrical box 41 is installed on the outside of a side panel 14 for wiring electrical components. A through-hole is provided on one side of the electrical box 41, and a collection box is provided inside the through-hole of the electrical box 41. An exhaust pipe 71 is provided on one side of the dust collector 7 for discharging adsorbed dust. The exhaust pipe 71 is fixedly connected to a pipeline (not shown in the figure) through a rotary joint, and the other end of the pipeline is connected to the through-hole to realize dust collection.

[0053] In this embodiment, the inoculant particles are transported to the unloading platform 5 by a conveyor, dried and dust-removed by an electric heater 6 and a dust collector 7, and fall into the hopper 12 along the inclined bottom surface of the unloading platform 5. The flow rate of the inoculant particles is controlled by the intelligent electric control valve in the hopper 12 according to demand. The particles first fall from the hopper 12 onto the first conveyor belt 13. At this time, the particles with a diameter smaller than the aperture of the filter screen of the first conveyor belt 13 will pass through the filter screen and fall into the first trough 31 for collection, that is, the collection of small-particle inoculant. During the transportation of the particles on the first conveyor belt 13, the blades 24 are continuously moved upward. The conveyor belt 13 is moved back and forth and rotated downward, thereby breaking up the small particles of inoculant agglomerated on the first conveyor belt 13, so that the small particles can pass through the filter of the first conveyor belt 13 normally and fall into the first trough 31. The inoculant particles that do not enter the first trough 31 will continue to be conveyed by the first conveyor belt 13, and fall onto the second conveyor belt 32 through the first receiving plate 30. At this time, the particles with a diameter smaller than the aperture of the filter of the second conveyor belt 32 will pass through the filter and fall into the second trough 39 for collection. Finally, the particles that do not pass through the conveyor belt filter are large particles, which fall into the third trough 40 through the second receiving plate 38 for collection.

[0054] Embodiment 2;

[0055] On the basis of the first embodiment, the following structure is added: Figure 8 、 9 A rotating shaft 34 is hinged on the inner wall of the second guard plate 33. A second motor is fixedly connected to the upper side of the rotating shaft 34 through a coupling. The second motor is a bidirectional motor. A baffle 35 is fixedly connected to the rotating shaft 34. The baffle 35 is flipped by the drive of the second motor to control the passage of the inoculant particles on the surface of the second conveyor belt 32.

[0056] The second guard plate 33 is provided with an electric push rod 36, and a cover is provided on the outside of the electric push rod 36, and the cover is fixedly connected to the outside of the second guard plate 33, so as to realize the installation of the electric push rod 36, and a clamping assembly 37 is fixedly connected to the output end of the electric push rod 36, and the clamping assembly 37 includes a clamping plate 371, and the clamping plate 371 is fixedly connected to the output end of the electric push rod 36, and a micro motor 372 is installed inside the clamping plate 371, and a rotating wheel 373 is fixedly connected to the rotating wheel 373. A plurality of connecting rods are fixedly connected to the rotating wheel 373, and the other end of the connecting rod is fixedly connected to a clamping arm 374. The opposite surfaces of the two clamping arms 374 are clamping surfaces, and pressure sensors are installed in the two clamping surfaces. The circuit of the pressure sensor is connected in the cover, which is convenient for maintenance. When the micro motor 372 drives the rotating wheel 373 to rotate, the connecting rod rotates to drive the clamping arm 374 to clamp. After the clamping arm 374 contacts the large particle, the pressure parameter is fed back through the pressure sensor, which is the pressure currently borne by the large particle.

[0057] A recovery box is installed below the second conveyor belt 32 . The recovery box is located below the clamping assembly 37 and is used to recover broken inoculant particles.

[0058] In general, particles on the second conveyor belt 32 are transported to the baffle 35 because they fail to fall through the filter screen of the second conveyor belt 32. Therefore, these particles are large particles. Large particles are used for thick and large castings or slow cooling processes to avoid shrinkage in the later stage due to premature exhaustion of inoculant elements. Therefore, the required compressive strength is required to be high. When the large particles are guided by the baffle 35 and transported to the clamping assembly 37, the electric push rod 36 extends from the clamping assembly 37 and clamps the large particles, thereby achieving the effect of judging the compressive strength of the large particle inoculant.

[0059] Perform random compressive strength tests on large-particle inoculants to ensure their reliability. When large particles are conveyed on the second conveyor belt 32, the baffle 35 is rotated to adjust the plate spacing, controlling the large particles to sequentially enter the area where the clamping assembly 37 is located on the second conveyor belt 32. The camera 11 assists in locating the position of the large particles, and then the two electric push rods 36 extend to clamp a single large particle. The compressive strength of the large-particle inoculant is set to P1, and the pressure parameter fed back by the pressure sensor on the clamping arm 374 is P2. A random inspection is performed at intervals t1. After completing the inspection of m large particles, the required pass rate is x%;

[0060] When P2 reaches P1 stably and does not change any more, it indicates that the compressive strength of the large particle inoculant is qualified. The clamping assembly 37 releases the large particle and continues to convey it to the third trough 40 for collection via the second conveyor belt 32.

[0061] When P2 reaches P1 or does not reach P1, and the value of P2 changes to 0 instantly, it means that the large particle inoculant is broken and the compressive strength is unqualified. The broken particles will pass through the filter of the second conveyor belt 32 and fall into the recovery box for collection.

[0062] Furthermore, the remote control terminal continuously collects statistics on the random inspection results until the qualified rate of large particles in the random inspection is greater than a preset x%, and the number of inoculant particles inspected when the qualified rate reaches x% is set to n;

[0063] If n≤m, the large particles in this batch have good compressive strength. In this case, the detection interval is adjusted to 2t1, which reduces the detection frequency and improves the overall sorting efficiency.

[0064] If n>m, the compressive strength of the large particles in this batch is poor. At this time, the detection time interval is adjusted to t1 / 2, and the detection frequency of the large particle inoculant is increased. At the same time, due to the high unqualified rate at this time, the number of large particles that are crushed is large, and the amount of dust caused will increase. At this time, through the rotation of the driving part 1 and the driving part 2, and the extension of the pneumatic support rod 10, the dust collector 7 is adjusted to the surface of the second conveyor belt 32 with the air intake facing the air intake, and the air is sucked out of the dust on the surface to prevent excessive dust adhesion from affecting the detection accuracy.

[0065] Through this embodiment, random sampling detection of the compressive strength of large-particle inoculant is achieved, which not only ensures the reliability of the detection of large-particle inoculant, but also can flexibly adjust the detection strategy according to actual conditions, improve the overall sorting efficiency, and effectively prevent dust from affecting the detection accuracy.

[0066] Embodiment 3;

[0067] In order to ensure the stable operation of the device, it is necessary to ensure that the output of the inoculant particles is consistent with the collection situation. Specifically, the discharge amount fed back by the intelligent electric control valve at the discharge port of the hopper 12 is set to G, and the first load cell, the second load cell, and the third load cell respectively feed back the collection weights of the first trough 31, the second trough 39, and the third trough 40 as G1, G2, and G3. The data is processed by the remote control terminal, and the total weight of each trough ΣG=G1+G2+G3 is calculated in real time and compared with the total feed amount G. The allowable error threshold is set to ΔG;

[0068] When |ΣG - G|>ΔG, it indicates that there is a blockage abnormality in the sorting process. First, the intelligent electric control valve is closed to stop feeding. After the conveyor belts have completed their circumference rotation and conveying, the second conveyor belt 32 is stopped. The surface area of ​​the first conveyor belt 13 is scanned by the camera 11 to identify the location of material accumulation or jamming.

[0069] If the camera 11 detects that there is accumulation or blockage on the first conveyor belt 13, the rotating motor of the paddle 24 is controlled to increase the speed and the up and down reciprocating frequency to break up the accumulated particles, and the roller brushes 29 on both sides of the first conveyor belt 13 are started synchronously. When the identified blockage moves below the paddle 24, the roller brushes 29 are driven upward by the linear motor to make them further contact with the filter screen of the first conveyor belt 13 and eject the blocked particles. At the same time, the dust collector 7 is adjusted to face the surface of the first conveyor belt 13 with the air intake, and air is sucked above the roller brush 29. With the ejection of the roller brush 29, the blockage is discharged from the filter screen and falls on the surface of the filter screen. In order to ensure accurate dredging of the blockage, when the blockage moves below the roller brush 29, the roller brush 29 will be driven downward again by the linear motor to eject the blockage again, thereby enhancing the dredging effect.

[0070] If the camera 11 does not observe accumulation or blockage on the first conveyor belt 13, the operation of the first conveyor belt 13 is stopped and the operation of the second conveyor belt 32 is started. If the camera 11 observes accumulation or blockage on the first conveyor belt 13, the motor 2 on the rotating shaft 34 is started to reciprocate the baffle 35, thereby combing the accumulation on the second conveyor belt 32 to a certain extent. At the same time, the dust collector 7 faces the surface of the second conveyor belt 32 and performs the same operation with the roller brush 29 as the blockage treatment of the first conveyor belt 13.

[0071] After completing the above operations, open the intelligent electric control valve again to feed the material, and feedback the total weight of each trough ΣG and the total feed amount G. If |ΣG - G|≤ΔG, it indicates that the device is operating normally. If |ΣG - G|>ΔG, it is necessary to suspend the operation of the entire device and perform necessary maintenance operations.

[0072] Furthermore, based on the second embodiment, when n>m, a large number of large particles cannot reach the qualified value of compressive strength. If |ΣG - G|>ΔG occurs at this time, it means that the number of unqualified large particles exceeds the threshold range. At this time, the random inspection of the compressive strength of the large particle inoculant is stopped, and the set compressive strength standard P1 is re-evaluated. The P1 value is appropriately lowered based on the actual situation of the current batch of inoculant. At the same time, the output power of the micro motor 372 is fine-tuned to optimize the clamping force of the clamping arm 374 to avoid unnecessary particle breakage due to excessive clamping. After the adjustment is completed, the random inspection of large particles is restarted, and the inspection results and the deviation between the total weight ΣG of each trough and the total feed amount G are observed, and the same processing is performed;

[0073] Through this embodiment, the output of the inoculant particles is compared with the collection amount of each trough in real time, the blockage anomaly in the sorting process is discovered in time, and targeted and effective measures are taken for blockage and other situations. The blockage problem can be handled in time, the stable operation of the device is ensured, and the reliability and production efficiency of the device are improved.
