Description

Technical Field

[0001] This invention relates to the field of grain and oil by-product processing equipment, and in particular to an integrated pulse airflow drying and pulverizing device for camellia oil cake. Background Technology

[0002] In the deep processing of agricultural by-products such as camellia oil cake and meal, the materials need to be crushed and dried. Air jet milling is one of the common crushing methods. It uses high-speed airflow to drive the material particles to collide, rub against each other and impact the wall of the chamber to achieve crushing. At the same time, the airflow also has a certain drying effect. Common such devices usually include a feeding mechanism, a crushing chamber with airflow nozzles, and a cyclone separator for gas-solid separation. In practical applications, it has been found that the above-mentioned general structure has room for improvement when processing materials such as camellia oil cake and meal, which have a certain degree of viscosity and may have uneven initial moisture content. Simply crushing the material by high-speed airflow is not very effective and often requires multiple reflow operations in the process. Secondly, after the device finishes working and stops, a small amount of material will inevitably remain inside the crushing chamber and the grading mechanism. If the residue accumulates in the key airflow channels, it may become damp and clump together when the equipment is restarted, affecting the dynamic balance or obstructing the airflow, which will bring uncertainty to the stability and efficiency of the next operation. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as mediocre pulverization effect on materials like camellia oil cake and residue, inconvenient residue cleaning, and easy clogging of air ducts. Therefore, this invention proposes an integrated pulse airflow drying and pulverizing device for camellia oil cake and residue.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An integrated pulse airflow drying and pulverizing device for camellia oil cake includes a hopper and a screw feeder located below and connected to the hopper, and further includes: A pulverizing and drying device includes a pulverizing and drying chamber, a lower chamber, an airflow chamber, and a feeding chamber. The pulverizing and drying chamber has a cylindrical grading chamber for pulverizing materials. The airflow chamber has high-pressure air inlet nozzles arranged at equal intervals for pulverizing materials. The lower part of the airflow chamber has a movable temporary storage chamber for storing materials. The pulverizing and drying chamber and the airflow chamber are respectively equipped with adjusting components for adjusting the feed rate and airflow.

[0005] In one possible design, a cyclone separator is also included. The feed inlet of the screw feeder and the discharge outlet of the hopper are connected by the same pipe I. The screw blades inside the screw feeder are connected to a separately driven motor I. A connecting connector is provided at the top of the feed chamber. The connector and the discharge outlet of the screw feeder are connected by the same pipe II. The discharge outlet of the crushing and drying chamber is connected to the cyclone separator by the same pipe III.

[0006] In one possible design, the lower chamber is located at the bottom of the pulverizing and drying chamber, the airflow chamber is located on one side of the lower chamber and is inclined, and the feed chamber is located on one side of the pulverizing and drying chamber.

[0007] In one possible design, the classification chamber is rotatably disposed inside the pulverizing and drying chamber, and the pipe III is connected to one end of the classification chamber. The outer wall of the classification chamber has axially arranged slots, and multiple slots are arranged in a ring at equal intervals. A drive motor II is fixedly disposed on the outside of the pulverizing and drying chamber. The drive motor II has a dual-shaft structure, and its two output shafts are output shaft I and output shaft II, respectively. The output shaft I is coaxial with and connected to the classification chamber. A mounting base is fixedly provided at the end of the airflow chamber, and multiple high-pressure air intake nozzles are fixedly provided on the mounting base, with the high-pressure air intake nozzles facing the classification chamber.

[0008] In one possible design, the interior of the lower chamber and below the connection port of the feed chamber is configured as a temporary storage chamber. The bottom wall of the temporary storage chamber is configured as a rotatable guide plate, and the guide plate is inclined. Hooks are provided between the back of the guide plate and the lower inner wall of the pulverizer and dryer, and tension springs are connected between the hooks.

[0009] In one possible design, the regulating element includes an arc-shaped baffle and air holes formed on the surface of the baffle. The baffle is located inside the airflow chamber and its bottom end is fixedly disposed with a guide plate.

[0010] In one possible design, a guide frame is also included. The main body of the guide frame consists of two parallel guide rods. The outer wall of the lower chamber is provided with a connecting shaft that is connected to the rotating shaft of the guide plate. An end seat is fixedly sleeved on the outer wall of the connecting shaft and the end seat is fixedly connected to the guide rod. The output shaft of the output shaft II is fixedly sleeved with a rotating wheel. An eccentric rod is fixedly provided on the surface of the rotating wheel. A sliding sleeve seat is slidably sleeved on the outer wall of the guide rod and the sliding sleeve seat is sleeved on the outer wall of the eccentric rod.

[0011] In one possible design, the adjusting component further includes a flow divider plate. Guide rails are provided on both sides of the inner wall of the pulverizing and drying chamber near the feeding chamber. The flow divider plate is slidably disposed between the two guide rails, and the surface of the flow divider plate is provided with partition holes. A protective plate that cooperates with the guide rail is fixedly provided on one side of the surface of the flow divider plate, and a connecting frame that cooperates with the partition plate is fixedly provided at the bottom of the flow divider plate.

[0012] In one possible design, a scraper ring located outside the grader and movable along the axis is also included, the inner wall of which is provided with a protrusion extending into the interior of the connecting plate.

[0013] In one possible design, the two ends of the strip hole are respectively set as end I and end II, the outer wall of the scraper ring is provided with a guide groove, and the guide groove is provided with an inclined guide surface facing the inner side wall of end II. The inside of the pulverizing and drying chamber is fixedly provided with a limiting strip that cooperates with the scraper ring. The periphery of the grading chamber is provided with a stop ring that moves along the axis, and the inner wall of the feeding chamber is provided with a movable plate that can move outward. A connecting plate is fixedly provided between the movable plate and the stop ring.

[0014] In this application, during actual use, the material enters the hopper through a valve and is then fed to the pulverizing and drying chamber below via a screw feeder. Specifically, the material slides down the ramps of the connector and the feed chamber into the pulverizing and drying chamber and falls into the lower chamber. Compressed air is injected into the lower chamber and the pulverizing and drying chamber using high-pressure air nozzles, causing the material to accelerate in the supersonic jet stream and achieve a pulverizing effect through repeated impacts and collisions by multiple high-pressure air nozzles. Simultaneously, air drying is performed. The pulverized material enters the classifying chamber with the rising airflow and impacts the surface of the classifying chamber, achieving a further pulverizing effect. Since the classifying chamber rotates at high speed via drive motor II, the pulverized material entering the classifying chamber through the slots will be subjected to centrifugal force. The centrifugal force of larger particles will be greater than the centripetal force of the airflow viscosity, thus causing a second impact for further pulverization. Smaller particles will enter the cyclone separator with the airflow for separation. When the device is in normal use, the rotation direction of the grading chamber is towards end I, while the initial position of the scraper ring is at end II. At this time, due to the inclined inner wall of the slot, when the grading chamber rotates, its inner wall will squeeze the convex end of the scraper ring, giving it a force to move towards end II, so that the scraper ring continues to be located at end II. When the drive motor II is driven, the output shaft II drives the rotating wheel to rotate through the reducer. The rotating wheel drives the eccentric rod and the sliding sleeve seat on the outer wall to rotate. The sliding sleeve seat moves synchronously along the guide rod, causing the guide frame to rotate and swing back and forth along the end seat. The guide frame drives the guide plate to swing back and forth through the connecting shaft. The guide plate drives the baffle to move synchronously. The baffle will block the airflow channel of the airflow chamber, causing its flow cross section to periodically expand and contract, thereby forming a turbulent flow with variable velocity. When the device stops, the guide plate will be pulled by the tension of the spring, causing it to rotate downwards. Its end will move to the bottom of the temporary storage chamber, and the small amount of material falling freely by gravity above will fall onto the surface of the guide plate in the temporary storage chamber. Conversely, when the device starts, the guide plate will swing again, pushing the material upwards. When the guide plate is flush with the inner wall of the airflow chamber, the material will slide down the lower inner wall of the airflow chamber, thereby contacting the airflow and causing it to rush upwards again. Furthermore, when the baffle rotates upward, increasing the cross-sectional area of ​​the airflow chamber, the baffle will simultaneously push the connecting frame upward, thereby increasing the cross-section of the feed chamber and simultaneously increasing the amount of material falling. Conversely, when the baffle rotates downward, the diverter plate moves downward through the spring, reducing the amount of material falling, thus achieving a balance between the two. When the device stops, the material in the feeding chamber is discharged, and the material is no longer squeezed. This causes the movable plate to move under the force of the elastic element. The connecting plate drives the abutment ring to move, and the abutment ring will exert a force on the scraper ring to move continuously toward end I. The scraper ring is in contact with the end of the limiting strip. At this time, the classifying chamber is controlled to rotate in the opposite direction. The limiting strip will then enter the interior of the guide groove through the inclined guide surface and continue to rotate. Since the scraper ring is restricted from rotating, it is pushed to move axially through the inclined surface of the inner wall of the strip hole, thereby scraping off the residue on the inner wall of the strip hole.

[0015] In this invention, the pulse airflow drying and pulverizing integrated device for camellia oil cake has a guide plate that swings so that after the machine stops, the guide plate can return to its tilted state under the action of gravity and tension spring, thereby forming a temporary storage chamber to collect any material that may remain above, reducing the risk of it sliding into the airflow chamber area, and being able to send it back into the airflow range when the machine is started again. In this invention, the pulse airflow drying and pulverizing integrated device for camellia oil cake is equipped with an axially movable scraper ring, the protruding end of which extends into the slot of the grading chamber. When the grading chamber rotates in the reverse direction, it can push the scraper ring to move and scrape off the residual material attached to the inner wall of the slot, which facilitates cleaning of the grading mechanism after shutdown and reduces the risk of residue clumping and blockage. In this invention, during use, the material can be directly impacted by the high-pressure airflow below, causing it to collide and be crushed. Then, it will impact the high-speed rotating classifying chamber above, causing it to be further crushed. Large particles of material entering the classifying chamber will be thrown out again due to centrifugal force, thus enabling secondary crushing and improving the overall crushing effect.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] In one embodiment: Reference Figure 1 An integrated drying and pulverizing device is provided, which mainly includes a hopper 1, a screw feeder 2, a pulverizing and drying unit 3, and a cyclone separator 4.

[0020] The hopper 1 is used to temporarily store the raw material of camellia cake to be processed. Its bottom outlet is connected to the inlet of the screw feeder 2. The screw feeder 2 is equipped with a screw blade driven by a separate drive motor I 211. The outlet of the screw feeder 2 is connected to the inlet of the crusher and dryer 3 through the pipe II 512.

[0021] refer to Figure 2 The interior of the pulverizer 3 shell is divided into multiple functional chambers. The upper part of the shell is the pulverizing and drying chamber 311. The bottom of the pulverizing and drying chamber 311 is connected to the lower chamber 312. On one side of the lower chamber 312, there is an inclined airflow chamber 313. The axis of the airflow chamber 313 is at an angle to the horizontal plane. On the other side of the pulverizing and drying chamber 311, there is a feeding chamber 314. The top of the feeding chamber 314 is connected to the above-mentioned pipe II 512 through a connector 315.

[0022] refer to Figure 3Inside the pulverizing and drying chamber 311, a cylindrical classifying chamber 6 is provided. The classifying chamber 6 is supported by bearings and rotates relative to the inner wall of the pulverizing and drying chamber 311. Multiple slots 611 are provided axially on the cylindrical wall of the classifying chamber 6. The slots 611 are arranged in a ring at equal intervals and have an inclination. One end of the classifying chamber 6 is connected to the air inlet of the cyclone separator 4 through pipe III 513. On the outer wall of the pulverizing and drying chamber 311, a drive motor II 7 is fixedly installed. The drive motor II 7 has a double-shaft extension structure and has two output shafts: output shaft I 711 and output shaft II 712. The output shaft I 711 is coaxially connected to the rotating shaft of the classifying chamber 6 through a coupling and is used to drive the classifying chamber 6 to rotate.

[0023] refer to Figure 4 At the end of the inclined airflow chamber 313, a mounting base 9 is fixedly installed. Multiple high-pressure air inlet nozzles 10 are fixedly installed at equal intervals on the mounting base 9. The axes of the high-pressure air inlet nozzles 10 all point to the outer wall area of ​​the classification chamber 6. The high-pressure air inlet nozzles 10 are connected to an external compressed air source. Inside the lower chamber 312, directly below the opening of the feed chamber 314, a temporary storage chamber 3121 is formed. The bottom wall of the temporary storage chamber 3121 is a movable structure, specifically a guide plate 11 that can rotate around the axis away from the end of the airflow chamber 313. The guide plate 11 is arranged at an inclination. A tension spring 12 is connected between the back (lower surface) of the guide plate 11 and the lower inner wall of the pulverizer dryer 3 shell through a hook 1211.

[0024] refer to Figure 5-6 In this embodiment, the adjusting component includes an arc-shaped partition 8. The partition 8 is located at the channel opening of the airflow chamber 313. Its top end is a free end, and its bottom end is fixedly connected to the side of the guide plate 11 near the airflow chamber 313. The partition 8 has air holes 811. When the guide plate 11 swings, it will drive the partition 8 to swing synchronously, thereby changing the gap between the partition 8 and the inner wall of the airflow chamber 313, that is, changing the effective cross-sectional area of ​​the airflow channel.

[0025] The working process of the device is as follows: Camellia oil cake and meal material enters the screw feeder 2 from the silo 1 through the valve control. The screw blades are driven by the drive motor I 211 to convey the material at a controllable speed. The material falls into the feed chamber 314 through the pipe II 512 and connector 315, slides down its inner wall, and enters the lower chamber 312 through the bottom opening. At this time, external compressed air is injected into the airflow chamber 313 through the high-pressure air intake nozzle 10 in a pulse or continuous manner. The high-speed airflow performs preliminary impact, shearing and drying on the material. The material particles carried by the airflow are transported upward. The particles enter the pulverizing and drying chamber 311 and collide with each other and the chamber wall within the space, achieving further pulverization. Under the influence of airflow, the fine particles approach the high-speed rotating classification chamber 6. Particles with sufficiently small diameters can enter the interior of the classification chamber 6 through the slots 611 under the action of the viscous force of the airflow. They are then carried by the airflow through the pipe III 513 into the cyclone separator 4 for separation and collection. Particles with larger diameters, due to the centrifugal force they receive being greater than the centripetal force of the airflow, will be thrown towards the outer wall of the classification chamber 6, colliding at the edge area of ​​the slots 611, or falling back down to continue participating in the pulverizing cycle.

[0026] In this embodiment, the guide plate 11 is swingable and equipped with a tension spring 12 to avoid the phenomenon that the return position of the guide plate 11 may not be fixed or the return force may be insufficient when the device is stopped, relying solely on its own weight. After the device stops and the airflow stops, a small amount of material that falls freely from above by gravity will fall onto the surface of the guide plate 11 in the temporary storage chamber 3121. Conversely, when the device is started, causing the guide plate 11 to swing again, it will push the material upward. When the guide plate 11 is flush with the inner wall of the airflow chamber 313, the material will slide down along the lower inner wall of the airflow chamber 313, thereby contacting the airflow and causing it to rush upward again.

[0027] This application can be used in the field of grain and oil by-product processing equipment, or in other fields applicable to this application.

[0028] In another embodiment: Reference Figure 8An integrated pulse airflow drying and pulverizing device for camellia oil cake is applied to the field of grain and oil by-product processing equipment. The structure of this embodiment is basically the same as that of the aforementioned embodiment, except that the adjusting component also includes a diverter plate 14. Two vertical guide rails 1412 are fixedly installed on the inner wall of the pulverizing and drying chamber 311 near the feeding chamber 314. The diverter plate 14 is slidably embedded between the two guide rails 1412, and its plate surface can move up and down to partially block or open the opening connecting the feeding chamber 314 and the pulverizing and drying chamber 311. The diverter plate 14 has a partition hole 1411 for cooperating with the channel opening of the feeding chamber 314 to change its feed rate. A guard plate 1414 is fixed on one side of the diverter plate 14 to prevent material from entering the guide rail 1412 from the side. The bottom of the diverter plate 14 is connected to the arc-shaped partition plate 8 in the above embodiment through a connecting frame 1413.

[0029] refer to Figure 7 A rotating wheel 1316 is fixedly mounted on the output shaft II712 of the drive motor II7. An eccentric rod 1314 is fixed on the disc surface of the rotating wheel 1316. The device is also equipped with a guide frame 13, the main body of which consists of two parallel guide rods 1311. The connecting shaft 1315, which is connected to the rotating shaft of the guide plate 11, extends to the outside of the lower chamber 312 and has an end seat 1313 fixed at its end. The end seat 1313 is fixedly connected to two guide rods 1311. A sliding sleeve seat 1312 is sleeved on the guide rod 1311. The sliding sleeve seat 1312 is also sleeved on the eccentric rod 1314. When the drive motor II 7 is working, the output shaft II 7 12 drives the rotating wheel 1316 to rotate, and the eccentric rod 1314 moves in a circular motion and pushes the sliding sleeve seat 1312 to slide along the guide rod 1311. Thus, the guide plate 11 and the partition plate 8 are driven to reciprocate through the end seat 1313 and the connecting shaft 1315.

[0030] refer to Figure 9-10 In this embodiment, a scraper ring 18 that can move along the axis of the classification chamber 6 is also fitted around the periphery of the classification chamber 6. The inner wall of the scraper ring 18 is provided with a protruding end 1813, which extends into the slot 611 of the classification chamber 6. A guide groove 1811 is provided on the outer wall of the scraper ring 18. A limiting strip 19 is fixedly provided on the inner wall of the pulverizing and drying chamber 311. The limiting strip 19 can be engaged or disengaged from the guide groove 1811. The guide groove 1811 is close to the slot 611. The inner wall of the end II 613 is processed into an inclined guide surface 1812. On the inner wall of the feeding chamber 314, there is a movable plate 15 that can move outward under the action of external force. The movable plate 15 is fixedly connected to the abutment ring 17 sleeved around the periphery of the grading chamber 6 through the connecting plate 16. An elastic element (not shown in the figure, such as a spring) is provided between the movable plate 15 and the wall of the feeding chamber 314, so that the movable plate 15 has an outward movement tendency under normal conditions (when there is no material compression).

[0031] When the device is operating normally, the drive motor II7 simultaneously drives the classifying chamber 6 to rotate and the guide plate 11 to swing. The swing of the guide plate 11 drives the diverter plate 14 to move up and down synchronously through the partition plate 8 and the connecting frame 1413. When the partition plate 8 swings upward and the cross-section of the airflow channel increases, the diverter plate 14 moves upward, the opening of the feed port increases, and the feed rate increases. Conversely, when the partition plate 8 swings downward and the cross-section of the airflow channel decreases, the diverter plate 14 moves downward, the opening of the feed port decreases, and the feed rate decreases, thereby achieving a certain ratio of airflow and feed rate change.

[0032] When the device is crushing normally, the classification chamber 6 rotates with end I 612 facing the direction. Since the wall of the slot 611 is designed with an inclined surface, the rotation will generate an axial component force on the protruding end 1813 of the scraper ring 18 toward end II 613, so that the scraper ring 18 is stable in the position of end II 613.

[0033] When the device needs to be stopped, the material in the feed chamber 314 is emptied, and the movable plate 15 moves outward under the action of the internal elastic element. It pushes the abutment ring 17 and scraper ring 18 to move through the connecting plate 16. The scraper ring 18 moves until the guide groove 1811 on it is aligned with the fixed limit bar 19 and is locked in place. At this time, the scraper ring 18 is restricted from rotating. Then, the drive motor II 7 is controlled to make the classifying chamber 6 rotate in the opposite direction at a lower speed (i.e., end II 613 faces towards the end). Since the scraper ring 18 is restricted from rotating with the limit bar 19, the inclined inner wall of the reverse rotating bar hole 611 will generate a reverse thrust on the convex end 1813 towards end I 612, pushing the scraper ring 18 to move slowly towards end I 612. During this movement, the convex end 1813 will scrape off the residual material attached to the inner wall of the bar hole 611.

[0034] The device also includes a controller, which is electrically connected to the drive motor and the air supply solenoid valve of the high-pressure air inlet nozzle, respectively, and is used to control the feeding rate, the rotation speed and direction of the classifying chamber, the oscillation frequency of the guide plate, and the on / off and pressure parameters of the airflow, so as to realize the coordinated operation of the components.

[0035] In the process of processing oily dust from camellia seed cake, trace amounts of dust inevitably seep into the moving surfaces. During use, it is necessary to regularly clean and lubricate components such as shafts, sliding pairs, and springs, and promptly remove any adhering oily powder to ensure the long-term stable operation of the equipment.

[0036] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor and cyclone separator 4 are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0037] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
