Description

Technical Field

[0001] This utility model relates to the field of dust removal and feeding technology in chemical material production, and more specifically to a dust-free feeding station device. Background Technology

[0002] Sodium-ion batteries have experienced explosive growth in energy storage systems and low-speed electric vehicles due to their advantages of low cost, high safety, and resource sustainability. However, significant capacity bottlenecks still exist in the current material production process, with the inefficient raw material feeding process becoming a key obstacle to large-scale production.

[0003] In the production process of sodium-ion battery positive and negative electrode materials (such as layered oxide positive electrodes and hard carbon negative electrodes), the following core material feeding requirements must be met:

[0004] 1. High cleanliness: The material particle size is usually 5-20μm, which easily adsorbs environmental dust and causes batch contamination;

[0005] 2. High timeliness: The amount of material fed in a single batch is 500-2000kg, which needs to be matched with the production capacity of the downstream process.

[0006] 3. Low loss rate: The unit price of materials is as high as 500,000-1,500,000 RMB / ton, and residual loss directly affects production costs. Currently, gravity-type ton bag feeding devices are commonly used in production, but these devices have the following technical drawbacks:

[0007] 1. Low feeding efficiency: When feeding a full bag, due to the high viscosity and compaction of the powder materials, it relies on natural gravity to fall, and the emptying time of the ton bag is as long as 30-60 minutes per bag, and the discharge status needs to be continuously monitored manually.

[0008] 2. Severe dust pollution: Open feeding ports can easily lead to dust escape and foreign matter mixing in, and can also cause material oxidation and deterioration;

[0009] 3. High dependence on manual labor: 2-3 operators are required to complete processes such as hoisting ton bags, breaking bags, and vibrating to assist in material discharge, which increases the average daily labor cost per line;

[0010] 4. High residual loss: 5%-8% of the material at the bottom of the ton bag cannot be completely discharged due to arching, and the annual loss can reach 40-60 tons / production line;

[0011] 5. Cumbersome equipment inspection: The existing feeding station is equipped with dust removal fans that need to be inspected and cleaned regularly to remove dust residue. The dust removal filter cartridges also need to be replaced regularly, and manual inspection of the dust removal fans is required regularly to ensure that they are operating normally. Utility Model Content

[0012] The present invention provides a dust-free feeding station device that is highly efficient in feeding materials, reduces losses, and reduces labor costs, and can solve at least one of the above-mentioned technical problems.

[0013] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0014] A dust-free feeding station device includes a hopper, a feeder, a pulse vibrator, and a ton bag;

[0015] The fully loaded ton bag is aligned with the hopper inlet and fixed in place with the hopper. The feeder is placed at the hopper inlet and can penetrate into the interior of the ton bag. The feeder includes feeder blades and a central shaft. There are multiple feeder blades arranged circumferentially around the central shaft. The pulse vibrator is connected to the feeder and is used to drive the feeder to vibrate at the same frequency.

[0016] Furthermore, the feeder is vertically and centrally positioned inside the hopper inlet at the top of the hopper, with one part extending outwards from the hopper inlet and the other part extending inwards into the hopper.

[0017] Furthermore, the guide blades are arc-shaped and fixed along the length of the central axis, which is cylindrical, and the center line of the central axis coincides with the center line of the hopper inlet.

[0018] Furthermore, the pulse vibrator is fixed to the outer wall of the silo, and the vibration frequency is adjustable.

[0019] Furthermore, it also includes a support rod, which is fixed to the inner wall of the hopper and includes horizontally distributed crossbars and inclined reinforcing rods. One end of the support rod is connected to the feeder, and the other end is connected to the pulse vibrator.

[0020] Furthermore, it also includes a bracket and a base, the base supporting the bottom of the hopper, the bracket being positioned below the base, and the hopper outlet located at the bottom of the hopper passing downward through the bracket.

[0021] Furthermore, it also includes a weighing module, which is located between the base and the support, with its top abutting against the base and its bottom abutting against the support. The weighing module is electrically connected to the pulse exciter and is used for real-time weighing to determine whether the pulse exciter is turned off.

[0022] Furthermore, it also includes an observation port, which is located on the side wall of the silo and is used to observe the internal condition of the silo and the feeder.

[0023] Furthermore, the top and bottom of the ton bag are respectively provided with a feed inlet and a discharge outlet. The outer diameter of the discharge outlet matches the inner diameter of the hopper inlet, and the inner diameter of the discharge outlet is larger than the outer diameter of the feeder.

[0024] The beneficial effects of this utility model are reflected in:

[0025] 1. Efficiency Improvement: With the combined action of the pulse vibrator and the feeder, the vibration effect at the bottom of the ton bag can be increased, the material residue on the inner wall and bottom of the ton bag can be reduced, the production line yield can be improved, the loss can be reduced, the ton bag emptying time can be shortened, and the feeding efficiency can be improved.

[0026] 2. Improve material jamming: Improve the feeding efficiency of existing feeding stations, reduce material sticking and jamming, and increase production line utilization.

[0027] 3. Reduce costs and increase efficiency: Avoid frequent manual lifting and lowering of ton bags, reduce manual intervention workload, and lower labor costs.

[0028] 4. Clean and high-quality production: During the feeding process, the ton bag is tightly sealed to the silo inlet to prevent the silo inlet from being open, thus avoiding dust leakage and causing problems such as loss, foreign matter mixing, material oxidation and deterioration, and environmental pollution.

[0029] 5. Energy saving and environmental protection: Replaces dust removal fans with pulse vibrators to reduce energy consumption.

[0030] 6. High compatibility: It is suitable for feeding materials with particle sizes from 5-50μm to 1-3mm, with a higher compatibility rate and a wider range of applications. Attached Figure Description

[0040] It should be noted that those skilled in the art will understand that all or part of the steps implemented in the embodiments of this utility model can be implemented entirely or partially by software, hardware, firmware, or any combination thereof. When implemented in hardware, it can be implemented entirely or partially by purchasing standard parts or modified parts.

[0041] See Figure 5 The existing feeding station has the following defects:

[0042] Low feeding efficiency: When feeding materials at the feeding station, the feed inlet of the ton bag is kept closed to prevent the spread of feeding dust. When the operator opens the ton bag to discharge the material, due to the viscosity between the materials and the negative pressure of the ton bag, the material in the ton bag enters the hopper by its own gravity, resulting in a slow discharge speed.

[0043] High reliance on manual labor: During the feeding process, there is a phenomenon of material arching, and operators need to frequently lift and lower the ton bag, and swing the ton bag again to assist in feeding. The open feeding port is prone to dust escape and residue mixing in, which also causes the material to oxidize and deteriorate.

[0044] The equipment inspection is cumbersome; the dust removal fan of the feeding station is prone to clogging, resulting in low dust removal efficiency, and manual inspection and filter cartridge replacement are required regularly.

[0045] High residual loss: Due to the large volume of the ton bag and the high hoisting height, the residual material at the bottom needs to be manually vibrated to assist in the discharge, which results in low discharge efficiency, high material accumulation and loss, and affects product yield.

[0046] See Figures 1-4 To address the aforementioned deficiencies, this utility model provides a dust-free feeding station device, comprising a silo 4, a feeder 11, a pulse vibrator 13, and a ton bag 21.

[0047] The ton bag 21, fully loaded with material, is aligned with the hopper inlet 9 and fixed in place with the hopper 4. The feeder 11 is placed at the hopper inlet 9 of the hopper 4 and can penetrate into the interior of the ton bag 21. The feeder 11 includes feeder blades 14 and a central shaft 15. There are multiple feeder blades 14, which are circumferentially spaced around the central shaft 15. The pulse vibrator 13 is connected to the feeder 11 and is used to drive the feeder 11 to vibrate at the same frequency.

[0048] See Figure 1 In this embodiment, the feeder 11 is vertically and centrally positioned inside the hopper inlet 9 located at the top of the hopper 4, with one part extending outward from the hopper inlet 9 and the other part extending inward into the hopper 4.

[0049] See Figure 2 In this embodiment, the guide blade 14 is arc-shaped and fixed along the length of the central axis 15. The central axis 15 is cylindrical, and the center line of the central axis 15 coincides with the center line of the hopper inlet 9.

[0050] Generally, to ensure that the powder material in the ton bag 21 can smoothly enter the hopper 4 and maximize the guiding effect, the overall height of the guide 11 is set to 40-60cm, the positioning height of the guide 11 exceeds the platform height of the hopper inlet 9 by 10-15cm, the diameter of the central shaft 15 is set to 5-8cm (the size does not exceed half the diameter of the outlet 23 of the ton bag 21), the thickness of the guide blade 14 is set to 2-4mm, and the width is set to 2-5cm. To prevent the upper blade of the guide 11 from puncturing the ton bag 21 or scratching the operator's limbs, the curvature of the guide blade 14 is set to 1-1.4rad.

[0051] To meet the feeding requirements of different materials, different feeding station devices are designed for different sections. The size and related parameters of the feeder 11 can be appropriately adjusted according to the material characteristics (such as particle size / viscosity) to achieve the best feeding effect. For example, if powder materials (median particle size of 5-50μm) are difficult to feed, the height of the feeder 11 is increased to 60cm and the diameter is 8cm, and the excitation frequency of the pulse vibrator 13 is increased to 20Hz to increase the contact area between the feeder 11 and the material, thereby improving the conveying efficiency of powder materials. For granular materials (median particle size of 1-3mm), the excitation frequency is adjusted to 50Hz to increase the vibration effect between the bottom of the hopper 4 and the bottom of the ton bag 21, reduce the material residue in the ton bag 21, and improve the material utilization rate.

[0052] See Figure 1 In this embodiment, the pulse vibrator 13 is fixed to the outer wall of the hopper 4, and the vibration frequency is adjustable, ranging from 20Hz to 50Hz.

[0053] See Figure 1 In this embodiment, a support rod 12 is also included. The support rod 12 is fixed to the inner wall of the hopper 4 and includes horizontally distributed crossbars and inclined reinforcing rods. One end of the support rod 12 is connected to the feeder 11 and the other end is connected to the pulse vibrator 13.

[0054] See Figure 1 In this embodiment, a bracket 6 and a base 7 are also included. The base 7 supports the bottom of the hopper 4, the bracket 6 is placed below the base 7, and the hopper outlet 10 located at the bottom of the hopper 4 passes downward through the bracket 6.

[0055] See Figure 1 In this embodiment, a weighing module 5 is also included. The weighing module 5 is located between the base 7 and the support 6, with its top abutting against the base 7 and its bottom abutting against the support 6. The weighing module 5 is electrically connected to the pulse exciter 13 and is used for real-time weighing to determine whether the pulse exciter 13 is turned off.

[0056] See Figure 1 In this embodiment, an observation port 8 is also included. The observation port 8 is opened on the side wall of the hopper 4 and is used to observe the internal condition of the hopper 4 and the feeder 11.

[0057] See Figure 3 and Figure 4 In this embodiment, the top and bottom of the ton bag 21 are respectively provided with a feed inlet 22 and a discharge outlet 23. The outer diameter of the discharge outlet 23 matches the inner diameter of the hopper inlet 9, and the inner diameter of the discharge outlet 23 is larger than the outer diameter of the feeder 11.

[0058] Before feeding materials into the feeding station, the operator hoists the ton bag 21 to a position directly above the feeding station. The inlet 22 of the ton bag 21 remains closed, while the outlet 23 of the ton bag is opened and aligned with the hopper inlet 9. The ton bag 21 is then hoisted and gradually lowered until the outlet 23 at the bottom of the ton bag 21 is fully inserted into the hopper 4 and fits against the hopper inlet 9, and is fitted outside the guide 11. The pulse vibrator 13 is then turned on, and the vibration frequency is set to 30Hz. Since the guide 11 is connected to the pulse vibrator 13 through the support rod 12, it transmits vibration at the same frequency as the pulse vibrator 13. This reduces the viscosity of the powdery material inside the ton bag 21, disrupts the compaction between the powders, accelerates the material flow rate, and improves feeding efficiency.

[0059] Meanwhile, the pulse vibrator 13 is fixed to the outer wall of the hopper 4 and can transmit vibration to the bottom of the ton bag 21, promoting the flow of powder from the inner wall and bottom of the ton bag 21 into the hopper 4 and reducing material residue.

[0060] Furthermore, when the weighing module 5 reports that the weight in the current silo 4 has reached a threshold, it triggers the pulse vibrator 13 to shut down, the feeding ends, and the material is conveyed to the next process under negative pressure from the silo outlet 10.

[0061] In addition, after feeding is completed, the operator can check or clean the feeder 11 through the observation port 8, and can also observe the material holding condition inside the hopper 4.

[0062] In summary, this utility model provides a dust-free feeding station device that not only improves the feeding efficiency of existing feeding stations, breaks down van der Waals forces between powders, reduces material adhesion and jamming, and increases powder feeding speed, but also reduces material residue on the inner wall and bottom of ton bags, increases production line yield, and reduces losses. At the same time, it reduces labor costs, reduces manual operation and observation, and avoids the use of dust removal fans, replacing them with pulse vibrators to reduce equipment energy consumption.

[0063] It should be understood that the examples and embodiments described herein are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art can make various modifications or changes based on them. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
