Description

Technical Field

[0001] This utility model relates to the field of konjac flour processing technology, specifically to an airflow classification device for konjac flour processing. Background Technology

[0002] Konjac flour, as a widely used functional raw material, has extremely high application value in the food, pharmaceutical, and chemical industries. Different industries have significantly different requirements for its particle fineness and uniformity. For example, konjac flour used in products such as jelly and beverages in the food industry needs to have a fine particle size to ensure a smooth taste, while in some industrial fields, when used as an additive, there are more stringent standards for particle uniformity.

[0003] Currently, the grading and processing of konjac flour mostly relies on traditional sieving equipment or simple airflow grading devices. Traditional sieving equipment grades konjac flour by the size of the screen mesh, which not only easily causes the screen to clog due to the stickiness of the konjac flour, affecting the grading efficiency, but also makes it difficult to achieve high-precision particle size separation, especially for fine particles.

[0004] While existing airflow classification devices avoid screen clogging, they generally suffer from insufficient airflow control precision and uneven centrifugal force field distribution. Some devices cannot accurately control airflow velocity and flow rate, resulting in blurred separation boundaries between particles of different sizes, making it difficult to meet the classification precision requirements of high-end industries. Furthermore, some devices have unreasonable guide structure designs, leading to disordered airflow distribution within the classification chamber, which prevents konjac flour particles from being evenly stressed, further reducing classification quality. In view of this, we propose an airflow classification device for konjac flour processing. Utility Model Content

[0005] The purpose of this invention is to provide an airflow grading device for konjac flour processing. By setting up a diversion mechanism, an air inlet pipe, a fan, a solenoid valve, a guide column, a vibrating motor, and different unloading structures, it solves the problems of insufficient grading accuracy and low efficiency of traditional grading devices, which make it difficult to meet the industry's strict requirements for konjac flour particles.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An airflow grading device for konjac flour processing includes a base plate, a grading cylinder fixed to the base plate, an air inlet pipe installed near the bottom of the outer circumference of the grading cylinder, a fan installed on the inner wall of the air inlet pipe, an upper discharge pipe installed on the top surface of the grading cylinder, solenoid valves installed on the outer walls of both the upper discharge pipe and the air inlet pipe, a lower discharge pipe installed on the bottom surface of the grading cylinder, several flow guide columns for guiding the flow installed on the inner top surface of the grading cylinder, and a vibrating motor for unloading installed on the outer wall of the grading cylinder. The device also includes:

[0008] A diversion mechanism is installed inside the grading cylinder to grade the konjac powder entering the grading cylinder. The diversion mechanism includes a rotating roller rotatably connected to the grading cylinder, a diversion impeller coaxially fixed on the outer circumference of the rotating roller and located inside the grading cylinder, two pulleys located above the grading cylinder and used to drive the rotating roller to rotate, and a motor installed on the top surface of the grading cylinder and used to drive the two pulleys to rotate.

[0009] In a preferred embodiment, the rotating roller penetrates the top surface of the classifying cylinder and extends to the inside of the classifying cylinder near the middle position, and the diverting impeller is coaxially fixed to the outer circumferential wall of the rotating roller near the bottom end.

[0010] In a preferred embodiment, the diversion mechanism further includes a rotating rod coaxially fixed on the top surface of the rotating roller, a rotating shaft coaxially connected to the motor output shaft, and two pulleys connected by belt drive, with the two pulleys coaxially fixed on the outer circumferential walls of the rotating shaft and the rotating rod, respectively.

[0011] These two settings enable the diverter impeller to generate a centrifugal force field at the appropriate position, improving the grading targeting and allowing the motor to stably drive the roller and diverter impeller to rotate, ensuring stable power transmission.

[0012] In a preferred embodiment, a plurality of guide columns on the top surface of the classifier cylinder are arranged in a ring at equal intervals. The outer circumferential wall of the guide columns is provided with spiral guide grooves arranged from top to bottom, and the flow divider impeller does not contact the plurality of guide columns.

[0013] In a preferred embodiment, the solenoid valve on the outer wall of the air inlet pipe is installed at one end of the outer circumference of the air inlet pipe away from the classifier cylinder, and the upper discharge pipe is installed on the top surface of the classifier cylinder near the middle position, and both the air inlet pipe and the upper discharge pipe are connected to the inner cavity of the classifier cylinder.

[0014] In a preferred embodiment, a feed funnel connected to the inner cavity of the classifying cylinder is installed near the edge of the top surface of the classifying cylinder. Manual valves are installed on the outer wall of the feed funnel tube and the outer wall of the discharge pipe, and the discharge pipe is connected to the inner cavity of the classifying cylinder.

[0015] In a preferred embodiment, the bottom of the grading cylinder has a structure that is concave from all sides to the center, and the parts of the grading cylinder that come into contact with the feed funnel, the lower discharge pipe, the air inlet pipe and the upper discharge pipe are all provided with sealing rings.

[0016] These four settings make the spiral rise of the airflow more uniform, avoid component interference, improve airflow stability, make airflow control more precise, unload small particles more smoothly, optimize operation, make feeding and unloading controllable, facilitate operation, improve the practicality of the device, make the unloading of large particles more concentrated, enhance the sealing of the device, and reduce the impact of air leakage.

[0017] In a preferred embodiment, the grading cylinder is fixed to the top surface of the base plate by several support legs, an mounting plate is fixed to the outer wall of the grading cylinder, the vibration motor is mounted on the top surface of the mounting plate, and an anti-slip plate that matches the shape of the base plate is fixed to the bottom surface of the base plate, and the bottom surface of the anti-slip plate is provided with anti-slip texture.

[0018] This design ensures the grading cylinder is securely fixed, the vibrating motor is stably installed, the overall device operates smoothly, and the effects of sliding are reduced.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model achieves precise control and a spiral upward effect of airflow within the grading cylinder through the coordinated arrangement of the air inlet pipe, fan, solenoid valve, and guide column. The fan provides a stable airflow, and the solenoid valve can precisely control the airflow speed and flow rate. Combined with the spiral guide groove of the guide column, the airflow forms a spiral upward trend, providing a stable and controllable airflow environment for konjac powder grading. When the konjac powder enters the grading cylinder with the airflow, it can be evenly dispersed under the action of the spiral airflow, laying a good foundation for subsequent grading and achieving the effect of improving the stability and controllability of the grading environment.

[0021] 2. This utility model achieves precise grading and efficient unloading of konjac flour through the design of a diversion mechanism, a vibrating motor, and different unloading structures. The rotation of the diversion impeller generates a centrifugal force field, which, combined with the centripetal force of the airflow, causes konjac flour of different particle sizes to move along different trajectories. Small particles are collected from the upper unloading pipe, while large particles are unloaded from the lower unloading pipe. The vibrating motor can cause the konjac flour on the inner wall of the grading cylinder to slide off, avoiding residue. This process achieves precise grading of konjac flour, meeting the requirements of different industries for fineness and uniformity, and achieving the effect of improving grading accuracy and unloading efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-3 The present invention provides a technical solution: an airflow grading device for konjac flour processing, including a base plate 1, a grading cylinder 2 fixed above the base plate 1, an air inlet pipe 25 installed near the bottom of the outer circumference of the grading cylinder 2, a fan 28 installed on the inner wall of the air inlet pipe 25, an upper discharge pipe 26 installed on the top surface of the grading cylinder 2, a solenoid valve 27 installed on the outer wall of both the upper discharge pipe 26 and the air inlet pipe 25, a lower discharge pipe 23 installed on the bottom surface of the grading cylinder 2, a plurality of flow guide columns 29 for guiding flow installed on the inner top surface of the grading cylinder 2, and a vibration motor 31 for unloading installed on the outer wall of the grading cylinder 2.

[0031] The airflow classification of konjac flour can be achieved through the grading cylinder 2, air inlet pipe 25, fan 28, solenoid valve 27, upper discharge pipe 26, lower discharge pipe 23, guide column 29, and vibrating motor 31.

[0032] In this embodiment, the grading cylinder 2 is fixed to the top surface of the base plate 1 by several support legs 21. An installation plate 3 is fixed on the outer wall of the grading cylinder 2. The vibration motor 31 is installed on the top surface of the installation plate 3. An anti-slip plate 11 that matches its shape is fixed on the bottom surface of the base plate 1. The bottom surface of the anti-slip plate 11 is provided with anti-slip texture.

[0033] The supporting legs 21, mounting plate 3, and anti-slip plate 11 ensure that the grading cylinder 2 is firmly fixed and the vibration motor 31 is reliably installed. The device is not easy to slip during operation, thus improving the overall stability and safety.

[0034] like Figures 1-2 , Figure 4 Figure 5As shown, in addition to the above, it also includes: a diversion mechanism 4, which is set inside the grading cylinder 2 and is used to grade the konjac powder entering the grading cylinder 2. The diversion mechanism 4 includes a rotating roller 41 rotatably connected to the grading cylinder 2, a diversion impeller 42 coaxially fixed on the outer circumference of the rotating roller 41 and located inside the grading cylinder 2, two pulleys 45 located above the grading cylinder 2 and used to drive the rotating roller 41 to rotate, and a motor 44 installed on the top surface of the grading cylinder 2 and used to drive the two pulleys 45 to rotate.

[0035] By setting up a flow divider mechanism 4, the flow divider impeller 42 can be driven to generate a strong centrifugal force field during rotation. When konjac powder and airflow enter the grading cylinder 2 together, under the combined action of centrifugal force and centripetal force, konjac powder particles of different sizes will move along different trajectories to achieve grading.

[0036] Furthermore, the rotating roller 41 penetrates the inner top surface of the classifying cylinder 2 and extends to the interior of the classifying cylinder 2 near the middle position, and the diverting impeller 42 is coaxially fixed to the outer circumferential wall of the rotating roller 41 near the bottom end.

[0037] The roller 41 extends to the middle of the grading cylinder 2, and the diverting impeller 42 is fixed near its bottom end, so that the diverting impeller is in a suitable position and the generated centrifugal force field can act more accurately on the konjac flour, improving the grading targeting and effect.

[0038] Specifically, the diversion mechanism 4 also includes a rotating rod 43 coaxially fixed on the top surface of the rotating roller 41, a rotating shaft 47 coaxially connected to the output shaft of the motor 44, two pulleys 45 connected by a belt 46, and the two pulleys 45 are respectively coaxially fixed on the outer circumference of the rotating shaft 47 and the rotating rod 43.

[0039] The pulley 45 connected by the rotating rod 43, rotating shaft 47, and belt 46 of the diversion mechanism 4 enables the motor 44 to stably transmit power to the rotating roller 41 and the diversion impeller 42, ensuring their continuous and stable rotation and ensuring the continuity of the grading process.

[0040] like Figures 1-3 As shown, it is worth noting that several guide columns 29 on the inner top surface of the classifier cylinder 2 are arranged in a ring with equal spacing. The outer circumference of the guide column 29 is provided with a spiral guide groove arranged from top to bottom. The flow divider impeller 42 does not contact the several guide columns 29.

[0041] The annular, equally spaced guide columns 29 and spiral guide grooves, which do not contact the flow divider impeller 42, make the airflow spiral upward more uniform, avoid component interference, provide a stable airflow environment for konjac flour grading, and improve grading consistency.

[0042] It is worth noting that the solenoid valve 27 on the outer wall of the air inlet pipe 25 is installed at the end of the outer circumference of the air inlet pipe 25 away from the classifier cylinder 2, and the upper discharge pipe 26 is installed on the top surface of the classifier cylinder 2 near the middle position. Both the air inlet pipe 25 and the upper discharge pipe 26 are connected to the inner cavity of the classifier cylinder 2.

[0043] By using the solenoid valve 27 on the air inlet pipe 25, which is far away from the classifier cylinder 2, and the upper discharge pipe 26 in the middle of the top surface, the airflow control is more precise, the discharge path of small particles is smooth, the stagnation is reduced, and the classification efficiency and effect are optimized.

[0044] It is worth emphasizing that a feed hopper 22 connected to the inner cavity is installed on the top surface of the classifying cylinder 2 near the edge. Manual valves 24 are installed on the outer wall of the feed hopper 22 tube and the outer wall of the discharge pipe 23, and the discharge pipe 23 is connected to the inner cavity of the classifying cylinder 2.

[0045] The feeding hopper 22 and its upper and lower discharge pipes 23 are equipped with manual valves 24, which make the feeding amount and discharge timing controllable, convenient for operation and adjustment, adaptable to different processing needs, and improve the practicality of the device.

[0046] It is worth noting that the bottom of the classifying cylinder 2 is concave from all sides to the center, and sealing rings are provided at the parts of the classifying cylinder 2 that come into contact with the feed funnel 22, the lower discharge pipe 23, the air inlet pipe 25 and the upper discharge pipe 26.

[0047] The recessed structure at the bottom of the classifier cylinder 2 and the sealing rings at each connection point make the discharge of large particles more concentrated, enhance the sealing performance of the device, reduce air leakage, and ensure stable classification pressure.

[0048] It should be added that the two solenoid valves 27, the fan 28, the vibration motor 31, and the motor 44 are all electrically connected to the external PLC and the external power supply respectively through wires, and the external PLC is also electrically connected to the external power supply through wires.

[0049] Finally, it should be noted that the two solenoid valves 27, the fan 28, the vibration motor 31, the motor 44, and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0050] In this embodiment, during actual use, the feed pipe of the external cyclone separator is first tightly connected to the upper and lower discharge pipe 26. After the external PLC control device is started, the manual valve 24 of the feed funnel 22 is opened first, and the konjac powder enters the grading cylinder 2. The PLC controls the solenoid valve 27 of the air inlet pipe 25 to open, and at the same time, the blower 28 and the external cyclone separator are started. Air enters the grading cylinder 2 from the air inlet pipe 25 and forms a spiral upward airflow through the guide column 29.

[0051] The PLC starts the motor 44, which drives the roller 41 to rotate the flow divider impeller 42 and generate a centrifugal force field. The konjac powder is classified under the action of airflow and centrifugal force. Small particles are carried by the airflow to the upper discharge pipe 26, and the PLC opens the solenoid valve 27 on it, so that they enter the external cyclone separator and are collected; large particles fall onto the inner wall of the classifying cylinder 2.

[0052] After grading, the PLC shuts off the fan 28, motor 44 and external cyclone separator, closes the solenoid valve 27 between the air inlet pipe 25 and the upper discharge pipe 26, starts the vibration motor 31 to cause large particles on the inner wall to slide off, opens the manual valve 24 of the lower discharge pipe 23 to complete the unloading, and finally the PLC shuts off the vibration motor 31.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
