Description

Technical Field

[0001] The present invention belongs to the technical field related to petrochemical industry, and specifically discloses a material separator. Background Art

[0002] A kind of mixed material used in the petrochemical industry, in which the catalyst is in the shape of cylindrical particles, with a diameter of about 4 mm and a length of about 4 mm - 10 mm, and the color is light dark green. Another kind is white irregular inert particles with a diameter of about 3 mm - 15 mm. In production, it is necessary to separate the white inert particles or special materials with obvious color differences doped in the mixed material to achieve reuse, etc., so as to reduce the procurement cost of enterprises; Machine vision technology and visualization realize image presentation, and use the differences in color and shape between catalyst particles and inert particles in the material to be sorted for sorting, such as a color sorter; The color sorter evenly scatters and spreads the material to be sorted on the conveyor belt through a vibrator. An industrial camera is installed above the conveyor belt to take images. During the process of the conveyor belt transporting the material, the industrial camera continuously takes images and sends them to the upper machine vision processing system. Through the color three - primary - color model debugged in the machine vision system, image segmentation, classification, and coordinate calculation are completed. The upper computer controls the pneumatic sorting actuator at the rear end of the conveyor belt according to the processing results, and separates the mixed material into two categories: inert particles and catalyst particles; Before processing the raw material, pretreatment is required. The purpose of pretreatment is to separate the metal debris that may be mixed in the granular mixture to avoid damaging the internal components of the color sorter. Moreover, the shape of the metal impurities themselves may cause errors when being recognized by the industrial camera. To avoid this situation, we need to improve it. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems existing in the background art, and propose a material separator, including a color sorter main body. A feed bin is connected and installed above the color sorter main body. A corrugated plate is movably arranged in the middle of the feed bin. The corrugated plate is composed of electromagnetic plates. Lifting mechanisms are arranged at both ends of the corrugated plate. A trapezoidal filter rack is installed at the inner bottom of the feed bin. Rotary mechanisms are arranged on both sides of the trapezoidal filter rack. Rotary feeding mechanisms are symmetrically arranged on both sides inside the feed bin. Air blowers are arranged above one side of both sides inside the feed bin and at the position of the rotary feeding mechanism.

[0004] Preferably, the lifting mechanism includes a hydraulic cylinder. A cross - plate is fixedly installed on the upper surface of the corrugated plate. The bottom of the cross - plate is fixedly connected to the telescopic end of the hydraulic cylinder. The bottom of the hydraulic cylinder is connected to the outer wall of the feed bin through a support seat provided.

[0005] Preferably, the slewing mechanism includes rotating shafts respectively rotatably installed at both ends of one side of the trapezoidal filter rack. Transmission wheels are symmetrically sleeved outside the two rotating shafts. Transmission belts are commonly sleeved outside the symmetrically arranged transmission wheels outside the two rotating shafts. Multiple groups of paddles are arranged outside the two groups of transmission belts. A first motor is arranged at the end of one of the rotating shafts.

[0006] Preferably, the rotary feeding mechanism includes a driving shaft rotatably installed inside the bin. Fixing frames are equidistantly installed along the circumferential direction outside the driving shaft. Shoveling plates are arranged on one side of the outer walls of multiple groups of fixing frames. A circular frame is commonly installed at one end of multiple groups of fixing frames away from the shoveling plates. A baffle extends out from one side of the shoveling plate. The inner edge of the shoveling plate is arranged in an arc-shaped surface and a flat plate extends outwards from the bottom.

[0007] Preferably, the two driving shafts are connected by a commonly installed first pulley assembly. A second motor is fixedly arranged at one end of one of the driving shafts away from the circular frame. Installation boxes are arranged on both sides of the bin. The second motor is fixedly arranged outside the installation box. The first motor is fixedly installed inside the installation box.

[0008] Preferably, storage boxes are fixedly arranged at both ends of the outside of the bin and above the corresponding support seats. Cylinders are arranged at both ends inside the two groups of storage boxes. Connection blocks are fixedly arranged at one end of the two groups of cylinders close to each other. Two horizontally symmetrically arranged connection blocks are connected by a commonly arranged guiding plate. The guiding plate is inclined. A material suction mechanism is arranged on the outer surface of the guiding plate. Multiple groups of scraping blades are arranged on the lower edges of the guiding plate. Multiple groups of scraping blades are in movable contact with the V-shaped inner angles of the inner surface of the corrugated plate. A guiding seat is arranged on the lower surface of the corrugated plate.

[0009] Preferably, the material suction mechanism includes partitions respectively installed at both ends of the outer surface of the guiding plate. A dust removal pipe is commonly arranged between the two groups of partitions.

[0010] Preferably, suction boxes are communicated and installed on one side of the two dust removal pipes close to each other. One end of the dust removal pipe penetrates outside one of the partitions and a communicating pipe is connected inside.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By setting the lifting mechanism, the corrugated plate can be driven to move up and down, so that the corrugated plate deeply penetrates into the particles. When rising, the corrugated plate adsorbs the metal impurities in the particles.

[0012] By setting the slewing mechanism, the particles in the lower part of the bin can be pushed upwards, so as to ensure more uniform impurity treatment.

[0013] The rotating material delivery mechanism can push the particles brought to the top by the rotating mechanism in a circular motion through the shoveling plate combined with its own shape during the rotation process. It cooperates with the fan during the rotation process to blow the particles brought in by the shoveling plate to the outer surface of the corrugated plate, and then fall to the outside of the guide plate set nearby. The particles can be evenly spread on the outer surface of the guide plate through the guide plate, and then the spread particles are introduced to the top of the outer surface of the corrugated plate through its own inclination angle, thereby fully separating the metal impurities in the particles.

[0014] By arranging a dust removal pipe and a dust collection box above the guide plate, after the power of the corrugated plate is cut off, metal impurities can fall from the bottom of the corrugated plate to the guide plate. At this time, the guide plate is pushed to the outer surface of the corrugated plate by the cylinder and fits with it, reducing the impurities falling into the hopper of the color sorter body. The impurities left on the guide plate are sucked into the dust removal pipe through the dust collection box and then discharged. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation modes.

[0018] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0019] As Figures 1 - 9 shown, a material separator includes a color sorter main body 1. A feed bin 2 is connected and installed above the color sorter main body 1. A corrugated plate 6 is movably arranged in the middle of the interior of the feed bin 2. The corrugated plate 6 is composed of electromagnetic plates. Lifting mechanisms are arranged at both ends of the corrugated plate 6. A trapezoidal filter frame 13 is installed at the inner bottom of the feed bin 2. Rotary mechanisms are arranged on both sides of the trapezoidal filter frame 13. Rotary feeding mechanisms are symmetrically arranged on both sides inside the feed bin 2. Air blowers 8 are arranged above one side of both sides inside the feed bin 2 and at the position of the rotary feeding mechanisms. The color sorter main body 1 is composed of structures such as an industrial high-speed camera, a high-pressure air nozzle group, multiple partition hoppers, multiple collection hoppers, a vibrating conveyor belt, etc., which are prior arts and will not be elaborated too much.

[0020] The lifting mechanism includes a hydraulic cylinder 4. A cross plate 5 is fixedly installed on the upper surface of the corrugated plate 6. The bottom of the cross plate 5 is fixedly connected to the telescopic end of the hydraulic cylinder 4. The bottom of the hydraulic cylinder 4 is connected to the outer wall of the feed bin 2 through a set support seat 3. Driven by the hydraulic cylinder 4, the corrugated plate 6 moves upward in the feed bin 2 at a constant speed, so that the corrugated plate 6 can adsorb metal impurities over a large area. The reason for setting it in a corrugated shape is to increase the contact area with metal impurities, so that the corrugated plate 6 can adsorb more metal impurities.

[0021] The rotary mechanism includes rotating shafts 14 respectively rotatably installed at both ends on one side of the trapezoidal filter frame 13. Transmission wheels 29 are symmetrically sleeved on the outer sides of the two rotating shafts 14. Transmission belts 18 are jointly sleeved outside the symmetrically arranged transmission wheels 29 on the outsides of the two rotating shafts 14. Multiple groups of paddles 17 are arranged outside the two groups of transmission belts 18. A first motor 16 is arranged at the end of one of the rotating shafts 14. The first motor 16 drives the rotating shaft 14 to rotate. Under the connection of the transmission belt 18, multiple groups of paddles 17 cyclically turn the particles deep inside the feed bin 2 in a reciprocating form, aiming to comprehensively remove metal impurities in the later-stage particles.

[0022] The rotating feeding mechanism includes a drive shaft 26 rotatably installed inside the bin 2. Fixed brackets 25 are equidistantly installed along the circumferential direction on the outer side of the drive shaft 26. On one side of the outer walls of multiple groups of fixed brackets 25, shoveling plates 24 are provided. At one end of multiple groups of fixed brackets 25 away from the shoveling plates 24, a circular frame 7 is commonly installed. A retaining piece 28 extends out from one side of the shoveling plate 24. The inner edge of the shoveling plate 24 is arranged as an arc-shaped curved surface and a flat plate extends outwards from the bottom; The shoveling plate 24 penetrates into the particles by virtue of the flat plate. Driven by the rotation of the drive shaft 26, the circular frame 7 and the fixed brackets 25 drive the shoveling plate 24 to shovel up the particles and let the particles transition to the arc-shaped curved surface. Under the resistance of the retaining piece 28, some particles can be scattered during the rotation of the circular frame 7, so as to cooperate with the blower 8 to blow the particles towards the corrugated plate 6. Through the adsorption of the corrugated plate 6, the separation of metal impurities with particles is completed.

[0023] The two drive shafts 26 are connected by a first pulley assembly 9 installed together on the outside. At one end of one of the drive shafts 26 away from the circular frame 7, a second motor 27 is fixedly arranged. Installation boxes 10 are arranged on both sides of the bin 2. The second motor 27 is fixedly arranged on the outside of the installation box 10, and the first motor 16 is fixedly installed inside the installation box 10; When the second motor 27 starts, it drives the corresponding drive shaft 26 to rotate. By means of the arranged first pulley assembly 9, the two drive shafts 26 can be driven to rotate, and thus the corresponding circular frame 7 can rotate inside the bin 2.

[0024] At both ends of the outside of the bin 2 and above the corresponding support seats 3, storage boxes 11 are fixedly arranged. At both ends inside the two groups of storage boxes 11, cylinders 22 are arranged. At one end where the two groups of cylinders 22 are close to each other, connection blocks 30 are fixedly arranged. Between the two horizontally symmetrically arranged connection blocks 30, a guiding plate 12 is commonly arranged. The guiding plate 12 is inclined. A material suction mechanism is arranged on the outer surface of the guiding plate 12. Multiple groups of scraping pieces 20 are arranged along the lower edge of the guiding plate 12. The multiple groups of scraping pieces 20 are in movable contact with the V-shaped inner angle of the inner surface of the corrugated plate 6. A guiding seat 19 is arranged on the lower surface of the corrugated plate 6; Through the arranged cylinders 22, the corresponding connection blocks 30 can be driven to move, so that the distance between the guiding plate 12 and the corrugated plate 6 can be adjusted. When adsorbing metal impurities, it is ensured that the guiding plate 12 and the scraping pieces 20 keep a feeding interval from the corrugated plate 6. After the corrugated plate 6 discharges electricity in the later stage and processes the metal impurities, the scraping pieces 20 are caused to slide and fit with the V-shaped inner angle of the corrugated plate 6 to prevent the metal impurities from falling into the color sorter main body 1.

[0025] The material suction mechanism includes partition plates 23 respectively installed at both ends of the outer surface of the guiding plate 12. A dust removal pipe 21 is commonly arranged between the two groups of partition plates 23. The two partition plates 23 can place the dust removal pipe 21 above the guiding plate 12 for use. In this way, subsequent metal impurities can be adsorbed without delaying the particles from falling onto the guiding plate 12 for spreading out flat.

[0026] On one side where the two dust removal pipes 21 are close to each other, a dust suction box 15 is connected and installed. One end of the dust removal pipe 21 penetrates the outside of one group of partition plates 23 and is internally connected with a communicating pipe 31. The dust suction box 15 and the dust removal pipe 21 are connected to an external suction device through the communicating pipe 31, and can adsorb the metal impurities that fall onto the guiding plate 12 after the corrugated plate 6 discharges electricity.

[0027] Working principle: During use, two kinds of granular materials of different colors are poured into the material bin 2. The first motor 16 and the second motor 27 are both started to drive the rotating shaft 14 and the driving shaft 26 to rotate respectively. The rotating shaft 14 drives the conveyor belt 18 to rotate below the material bin 2, causing multiple paddles 17 on the outer side of the conveyor belt 18 to turn the particles inside. The driving shaft 26 drives the circular frame 7 to rotate, causing the shoveling plate 24 on the outer edge of the fixed frame 25 to rotate. The shoveling plate 24 rotates to turn the particles brought above by the paddle 17 in a large-diameter circular motion. The shoveling plate 24 shovels up the particles with the flat plate and the arc area and sprinkles them above the material bin 2 to ensure that the metal impurities are exposed. At this time, the fan 8 is started to blow the sprinkled particles towards the outer surface of the corrugated plate 6. The corrugated plate 6 is gradually pushed up by the hydraulic cylinder 4, and gradually drives the corrugated plate 6 to rise evenly. The particles fall onto the outer surface of the inclined guiding plate 12, and the particles are guided to the corrugated plate 6 by virtue of the inclined angle. The corrugated plate 6 adsorbs the metal impurities mixed in the particles by means of magnetic attraction. Through this method, the metal impurities in the particles can be fully processed. Then the particles fall onto multiple compartments of the color sorter main body 1 through the trapezoidal filter frame 13. The color sorter main body 1 evenly guides the particles to the lower part through its own vibrating conveyor belt. Multiple air nozzles and industrial cameras inside the color sorter main body 1 cooperate to blow and separate the particles with different recognized color differences, separate the two kinds of particles of different colors, and then evenly introduce them into the corresponding sorting hoppers for collection, that is, the sorting of particles of different colors is completed.
