Description

Technical Field

[0001] This application relates to the field of material feeding technology, and in particular to a feeding device. Background Technology

[0002] In the process of accurately and efficiently loading bulk granular and powdered materials into ton bags using specialized equipment, the precision and efficiency of material feeding control are key indicators for measuring equipment performance.

[0003] Existing feeding equipment typically has only one discharge channel. To prevent material from overflowing when the ton bag is nearly full due to the large flow of material impacting the bag at high speed, butterfly valves are often added to the discharge channel to control the flow. However, to ensure the efficiency of the initial feeding, the feeding openings are relatively large and the feeding speed is fast. Relying solely on butterfly valves cannot accurately control the material flow, and there will still be a large number of overfilling or underfilling situations, affecting the accuracy of material measurement. Utility Model Content

[0004] In order to improve the accuracy and reliability of feeding, this application provides a feeding device.

[0005] This application provides a feeding device. The technical solution adopted is as follows: A feeding device includes a base frame, a ton bag connected to the base frame, a hopper fixedly disposed on the base frame, and a first discharge channel and at least one second discharge channel disposed on the side of the hopper facing the ton bag, wherein the diameter of the first discharge channel is larger than the diameter of the second discharge channel. A first control element is provided on the first discharge channel, which is used to control the flow rate of the first discharge channel. A second control element is provided on the second discharge channel, which is used to control the flow rate of the second discharge channel.

[0006] By adopting the above technical solution, when rapid feeding is required in the early stage, the first control component controls the first discharge channel to be fully opened. The large diameter of the first discharge channel allows the material to fall into the ton bag quickly, achieving efficient operation. When the material is almost full, it is necessary to ensure the accuracy of feeding. The first control component controls the first discharge channel to be gradually closed, and the second control component controls the opening of the second discharge channel. The smaller diameter of the second discharge channel allows the material to fall into the ton bag slowly. This not only enables rapid feeding in the early stage and improves work efficiency, but also ensures the accuracy of feeding in the later stage, improving the accuracy and reliability of material metering. It also avoids the situation where a large flow of material impacts the material in the ton bag at a high speed when the material in the ton bag gradually increases to almost full, causing material to escape and preventing environmental pollution in the workshop. At the same time, it avoids increasing the workload of cleaning up the material scattered outside the ton bag.

[0007] Optionally, the first control component includes a first motor, on which a first baffle is rotatably connected. The first baffle is located within the first discharge channel and is adapted to the first discharge channel. The second control component includes a second motor, on which a second baffle is rotatably connected. The second baffle is located within the second discharge channel and is adapted to the second discharge channel.

[0008] By adopting the above technical solution, during the initial feeding, the first motor drives the first baffle to rotate vertically, ensuring that the material falls quickly and in large quantities into the ton bag. As the material in the ton bag gradually increases to 70-80%, the first motor drives the first baffle to rotate gradually, reducing the material's descent speed and preventing a large amount of material from impacting the material accumulation surface at high speed, thus avoiding dust generation and material escape. When the ton bag is almost full, the first motor drives the first baffle to rotate horizontally, sealing the first discharge channel and preventing a large amount of material from falling. At the same time, the second motor drives the second baffle to rotate gradually, allowing the material to fall slowly from the second discharge channel with a smaller inner diameter. This helps to control the accuracy of the material quantity and improves the accuracy and reliability of material metering.

[0009] Optionally, a connecting pipe is fixedly provided at one end of the second discharge channel away from the hopper, and the other end of the connecting pipe is connected to the first discharge channel.

[0010] By adopting the above technical solution, the connecting pipe connects the second discharge channel with the first discharge channel. The connection between the second discharge channel and the first discharge channel allows the material in the second discharge channel to flow out from the first discharge channel, ensuring that the material is accurately placed into the ton bag. This avoids some material spilling outside the ton bag when the second discharge channel is located on the side for feeding. At the same time, it can be adapted to ton bags of different sizes. For ton bags with smaller diameters, the material can still enter the ton bag through the first discharge channel.

[0011] Optionally, at least two cylinder assemblies are provided on the base frame, and the two cylinder assemblies are located on opposite sides of the first discharge channel. The cylinder assemblies are used to lift the ton bag handle and widen the ton bag opening.

[0012] By adopting the above technical solution, the cylinder assemblies located on both sides of the first discharge port can smoothly lift the ton bag, and expand the ton bag opening by retracting the lifting cylinder, preventing the ton bag from failing to fully expand on one side and causing feeding failure. At the same time, the extension and retraction of the lifting cylinder can adapt to ton bags of different heights, improving the adaptability of the feeding device.

[0013] Optionally, the cylinder assembly includes a fastener and a lifting cylinder. One end of the fastener is detachably connected to the base frame, and the other end of the fastener is detachably connected to the cylinder body of the lifting cylinder. A hook is detachably connected to the piston rod of the lifting cylinder.

[0014] By adopting the above technical solution, fasteners can be added to the base frame as needed to enable multiple cylinder components to lift the ton bag simultaneously. Faulty lifting cylinders or hooks can be removed and replaced in time to prevent material from being fed onto the outside of the ton bag and avoid equipment downtime. When a new ton bag needs to be installed or replaced, the lifting cylinder extends, and workers can hang the handle of the ton bag on the hook from the ground, avoiding the need for workers to climb to replace the ton bag. After the ton bag is replaced, the lifting cylinder retracts to lift the ton bag, preventing a large amount of material from falling quickly into the bottom of the ton bag during feeding, which would cause dust or material to escape. The lifted ton bag can effectively prevent material from escaping or scattering onto the outside of the ton bag.

[0015] Optionally, a cyclone chamber is fixedly installed above the hopper, and a filter channel is opened at the top of the cyclone chamber. A filter device is detachably connected inside the filter channel, and the filter device is used to discharge gas from the material.

[0016] By adopting the above technical solution, the cyclone chamber can separate materials and gases. After the material enters the cyclone chamber, it spirals down along the chamber wall into the hopper under the action of centrifugal force. The gas density in the material is lower than that in the material, so the gas rises in the cyclone chamber and is discharged through the filtration channel. The filtration device smoothly removes the gas and seals the material in the cyclone chamber, ensuring the normal operation of the equipment. The filtration device prevents the material from escaping from the filtration channel and avoids external dust, particles and other impurities from entering the cyclone chamber and affecting the material quality, thus improving the reliability of the feeding device. At the same time, the cyclone chamber can store materials, preventing the hopper from becoming full and preventing subsequent materials from being unable to enter, thus improving the continuity and efficiency of the feeding equipment.

[0017] Optionally, it also includes a feeding channel, one end of which is connected to the cyclone chamber, and the other end of which is connected to a blower. The end of the feeding channel near the blower is provided with an inlet channel, and the inlet channel is oriented upwards.

[0018] By adopting the above technical solution, the material is poured in from the inlet channel and falls directly into the feeding channel by its own gravity, avoiding the need for additional external force to push the material into the feeding channel when the inlet channel is located on the side. The blower blows the material entering the feeding channel into the cyclone chamber.

[0019] Optionally, one end of the feeding channel that connects to the cyclone chamber is tangential to the cyclone chamber.

[0020] By adopting the above technical solution, after the material enters the cyclone chamber from the feeding channel, it directly contacts the cyclone chamber wall. The material moves along the tangential direction of the inner wall of the cyclone chamber, ensuring that the material rotates centrifugally along the cyclone chamber wall, maximizing the effect of centrifugal force, improving the separation effect of gas and material, optimizing the material movement trajectory, ensuring the effect of material falling downward and gas rising, and avoiding material blockage.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. When rapid feeding is required in the early stage, the first control unit fully opens the first discharge channel. The large diameter of the first discharge channel allows the material to fall quickly into the ton bag, achieving efficient operation. When the bag is almost full, to ensure feeding accuracy, the first control unit gradually closes the first discharge channel, and the second control unit opens the second discharge channel. The smaller diameter of the second discharge channel allows the material to fall slowly into the ton bag. This not only enables rapid feeding in the early stage and improves work efficiency, but also ensures feeding accuracy in the later stage, improving the accuracy and reliability of material metering. It also prevents the material from overflowing when the ton bag gradually fills up and the material is about to be full, thus preventing environmental pollution in the workshop and avoiding the increased workload of cleaning up the material scattered outside the ton bag.

[0022] 2. During the initial feeding, the first motor drives the first baffle to rotate vertically, ensuring that a large amount of material falls quickly into the ton bag. As the material in the ton bag gradually increases to about 70-80%, the first motor drives the first baffle to rotate gradually, reducing the material's descent speed and preventing a large amount of material from impacting the material accumulation surface at high speed, thus avoiding dust and material leakage. When the ton bag is almost full, the first motor drives the first baffle to rotate horizontally, sealing the first discharge channel and preventing a large amount of material from falling. At the same time, the second motor drives the second baffle to rotate gradually, allowing the material to fall slowly from the second discharge channel with a smaller inner diameter. This helps to control the accuracy of the material quantity and improves the accuracy and reliability of material metering.

[0023] 3. A connecting pipe connects the second discharge channel to the first discharge channel, allowing material from the second discharge channel to flow out through the first discharge channel. This ensures accurate material delivery into the ton bag and prevents material from spilling outside the ton bag when the second discharge channel is located on the side. It also accommodates ton bags of different sizes; even for smaller diameter ton bags, material can still enter through the first discharge channel. The cylinder assemblies on both sides of the first discharge port can smoothly lift the ton bag and expand its opening by retracting the lifting cylinders, preventing feeding failure due to insufficient expansion on one side. The extension and retraction of the lifting cylinders also accommodates ton bags of different heights, improving the adaptability of the feeding device.

[0024] 4. Fasteners can be added to the base frame as needed to allow multiple cylinder components to lift the ton bag simultaneously. Faulty lifting cylinders or hooks can be removed and replaced in time to prevent material from being fed onto the outside of the ton bag and avoid equipment downtime. When a new ton bag needs to be installed or replaced, the lifting cylinder extends, and workers can hang the handle of the ton bag on the hook from the ground, avoiding the need for workers to climb to replace the ton bag. After the ton bag is replaced, the lifting cylinder retracts to lift the ton bag, preventing a large amount of material from falling quickly into the bottom of the ton bag during feeding, which would cause dust or material to escape. The lifted ton bag can effectively prevent material from escaping or scattering onto the outside of the ton bag.

[0025] 5. The cyclone chamber separates materials and gases. After entering the cyclone chamber, the material spirals down the chamber wall into the hopper under centrifugal force. Since the gas density within the material is lower than that of the material, the gas rises within the cyclone chamber and exits through the filtration channel. The filtration device smoothly removes the gas, trapping the material within the cyclone chamber to ensure normal equipment operation. The filtration device prevents material from escaping through the filtration channel, avoiding external dust, particles, and other impurities from entering the cyclone chamber and affecting material quality, thus improving the reliability of the feeding device. Simultaneously, the cyclone chamber can store material, preventing subsequent material from being unable to enter when the hopper is full, improving the continuity and efficiency of the feeding equipment. After entering the cyclone chamber through the feeding channel, the material directly contacts the chamber wall and moves tangentially along the inner wall, ensuring centrifugal rotation along the chamber wall, maximizing the centrifugal force, improving the separation of gas and material, optimizing the material's trajectory, ensuring the material falls downwards while the gas rises, and preventing material blockage.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a feeding device.

[0033] like Figure 1 The feeding device includes a base frame 11, which is a cuboid frame structure. The four supports of the base frame 11 are fixedly set on the ground. Four circumferential horizontal frames are fixedly set inside the four horizontal frames on the top of the base frame 11. A fixing structure is set between the supports and the horizontal frames of the base frame 11. A cylinder assembly 4 is detachably connected to the base frame 11. The cylinder assembly 4 is connected to a ton bag 12. A cyclone chamber 14 is fixedly installed on the base frame 11. The cyclone chamber 14 is a cylindrical structure. A filter channel 15 is opened at the center of the top of the cyclone chamber 14. The filter channel 15 is a circular opening structure. A filter device 16 is detachably connected inside the filter channel 15. The filter device 16 is a circular filter screen structure. A blower 52 is fixedly installed on one side of the base frame 11. The blower 52 is connected to a feeding channel 51. The other end of the feeding channel 51 is connected to the cyclone chamber 14. The end of the feeding channel 51 near the blower 52 is horizontally set. An inlet channel 53 is set at the end of the feeding channel 51 near the blower 52. The inlet channel 53 opens upward. The inner diameter of the end of the inlet channel 53 away from the feeding channel 51 is larger than the inner diameter of the feeding channel 51. The diameter of the inlet channel 53 gradually decreases from the end away from the feeding channel 51 to the end near the feeding channel 51. The inner diameter of the feeding channel 51 at the connection with the inlet channel 53 is smaller than the inner diameter of other positions of the feeding channel 51. The middle end of the feeding channel 51 is inclined upward. The end of the feeding channel 51 near the cyclone chamber 14 is connected to the top side of the cyclone chamber 14. The end of the feeding channel 51 away from the cyclone chamber 14 connected to the cyclone chamber 14 is tangent to the outer wall of the cyclone chamber 14.

[0034] like Figure 1 and Figure 2A hopper 13 is fixedly installed at the bottom of the cyclone chamber 14. The hopper 13 has a truncated cone structure, and the inner diameter of the top of the hopper is the same as the inner diameter of the cyclone chamber 14. The top of the hopper is smoothly connected to the cyclone chamber 14. A first discharge channel 21 and two second discharge channels 22 are connected at the bottom of the hopper 13. The inner diameter of the first discharge channel 21 is larger than the inner diameter of the second discharge channels 22. The inner diameters of the two second discharge channels 22 are the same, and the two second discharge channels 22 are located on opposite sides of the first discharge channel 21. Both the first discharge channel 21 and the second discharge channel 22 are vertically downward. A connecting pipe 23 is connected to the end of the discharge channel 22 away from the hopper 13. The inner diameter of the connecting pipe 23 is the same as the inner diameter of the second discharge channel 22. The connecting pipe 23 is inclined toward the first discharge channel 21. The end of the connecting pipe 23 away from the second discharge channel 22 is connected to the second discharge channel 22. The material in the second discharge channel 22 enters the connecting pipe 23 and finally falls from the end of the first discharge channel 21 away from the hopper 13 into the ton bag 12. A first control component 31 is provided on the first discharge channel 21, and a second control component 32 is provided on the second discharge channel 22.

[0035] like Figure 2 and Figure 3 The first control component 31 includes a first motor 311, which is fixedly mounted on the first discharge channel 21. The first motor 311 is located in the middle of the first discharge channel 21. The first motor 311 is rotatably connected to a first baffle 312, which is a circular plate structure. The first baffle 312 is located inside the first discharge channel 21 and is adapted to the first discharge channel 21. The second control component 32 includes a second motor 321, which is fixedly mounted on the second discharge channel 22. The second motor 321 is located in the middle of the second discharge channel 22. The second motor 321 is rotatably connected to a second baffle 322, which is a circular plate structure. The second baffle 322 is located inside the second discharge channel 22 and is adapted to the second discharge channel 22.

[0036] like Figure 4 Four cylinder assemblies 4 are detachably connected to the base frame 11. The cylinder assemblies 4 are located at the four ends of the top of the base frame 11. Each cylinder assembly 4 includes a fastener 41, which is detachably connected to the top of the base frame 11 by bolts. A lifting cylinder 42 is detachably connected to the end of the fastener 41 away from the base frame 11. The fastener 41 is detachably connected to the cylinder base of the lifting cylinder 42. A hook 43 is detachably connected to the piston rod of the lifting cylinder 42. The hook 43 is a snap-on hook 43.

[0037] In other embodiments, the bottom of the hopper 13 may be connected to a number of second discharge channels 22, such as one or three. The inner diameters of the multiple second discharge channels 22 may be different. When the material in the ton bag 12 gradually increases, the second discharge channel 22 with the larger inner diameter is closed first. The second discharge channel 22 may be located on the side of the first discharge channel 21 and directly lead to the ton bag 12.

[0038] The implementation principle of this application embodiment is as follows: When rapid material feeding is required in the early stage, the first control component 31 controls the first discharge channel 21 to be fully opened. The large diameter of the first discharge channel 21 allows the material to fall quickly into the ton bag 12, achieving efficient operation. When the material is almost full, it is necessary to ensure the accuracy of material feeding. The first control component 31 controls the first discharge channel 21 to be gradually closed, and the second control component 32 controls the opening of the second discharge channel 22. The smaller diameter of the second discharge channel 22 allows the material to fall slowly into the ton bag 12. This not only enables rapid material feeding in the early stage and improves work efficiency, but also ensures the accuracy of material feeding in the later stage, improves the accuracy and reliability of material metering, and also avoids the large flow of material impacting the material in the ton bag 12 at a high speed when the material in the ton bag 12 gradually increases to almost full, causing the material to escape, thus preventing environmental pollution in the workshop. At the same time, it avoids increasing the workload of cleaning up the material scattered outside the ton bag 12.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
