Description

Technical Field

[0001] This utility model relates to the field of coal powder packaging, specifically a feeding device for coal powder packaging coal buckets. Background Technology

[0002] The coal powder feeding device is a core component of the coal powder quantitative packaging system. Its main function is to accurately measure and quickly fill coal powder, dispensing bulk coal powder from large storage silos into standard coal drums (usually metal drums or composite medium bulk containers, IBCs) according to preset weights (e.g., 250kg, 500kg per drum). After the coal powder is filled and sealed, it needs to be conveyed out of the equipment through the feeding device.

[0003] In existing coal powder packaging bin feeding devices, during the coal powder packaging and feeding process, coal powder particles tend to accumulate on the roller surface of the roller conveyor due to electrostatic adsorption and gravity adhesion. Long-term accumulation of residual coal powder changes the contact friction coefficient between the roller and the bottom of the coal bin, causing the roller to slip (i.e., the roller rotates but the coal bin cannot move synchronously), disrupting the originally stable conveying rhythm, prolonging the single feeding cycle, and thus reducing the feeding efficiency of the coal powder packaging bins. Currently, the coal powder adhering to the roller surface needs to be cleaned manually one by one, which is a troublesome, time-consuming and labor-intensive process, thus reducing the cleaning efficiency of the roller. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a feeding device for a coal powder packaging coal bucket to solve the technical problem of the inconvenience of quickly cleaning the coal adhering to the roller surface.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for coal powder packaging coal buckets, comprising a coal powder packaging equipment and two roller conveyors. The coal powder packaging equipment has an internal mounting frame, and a cylinder is mounted on the mounting frame. The output end of the cylinder is connected to a push plate via a piston rod. A fixing frame is fixed at the bottom of the roller conveyors, and a threaded shaft is threadedly connected to the bottom of the fixing frame. A lifting plate is connected to the top of the threaded shaft via a bearing. Multiple mounting seats are mounted on the top of the lifting plate, and a scraper is provided on the top of each mounting seat.

[0006] By adopting the above technical solution, the roller conveyor serves as the conveying carrier for the coal bucket. The coal bucket to be filled with pulverized coal enters the equipment from one roller conveyor, while another roller conveyor transfers the coal bucket filled with pulverized coal from the packaging equipment to the next stage (such as storage).

[0007] Furthermore, multiple telescopic rods are installed at equal intervals between the lifting plate and the fixed frame.

[0008] By adopting the above technical solution, the telescopic rod restricts the movement direction of the lifting plate, avoids tilting during lifting, and ensures that the scraper and roller are always parallel and in contact.

[0009] Furthermore, a knob is installed at the bottom end of the threaded shaft, and the outer wall of the knob is provided with anti-slip texture.

[0010] By adopting the above technical solution, it is convenient for staff to rotate the threaded shaft with a knob, thereby enabling the threaded shaft to be raised and lowered.

[0011] Furthermore, a second shielding cylinder is provided between the bottom of the lifting plate and the fixed frame, and the second shielding cylinder is made of anti-static polyurethane material.

[0012] By adopting the above technical solution, the second shielding cylinder can shield the upper part of the threaded shaft, thereby forming a double protection in conjunction with the first shielding cylinder.

[0013] Furthermore, a first shielding cylinder is installed at the bottom of the fixing frame, and the first shielding cylinder is made of anti-static polyurethane material, and the bottom of the first shielding cylinder is tightly fitted to the top of the knob.

[0014] By adopting the above technical solution, the first shielding cylinder blocks coal dust from entering the lower gap of the threaded shaft, protecting the threaded shaft from dust corrosion, and the anti-static polyurethane material releases static electricity to avoid sparks.

[0015] Furthermore, the number of scrapers is the same as the number of rollers in the roller conveyor, and the scrapers correspond one-to-one with the rollers.

[0016] By adopting the above technical solution, it is ensured that each roller has its own dedicated scraper, thus avoiding missed areas.

[0017] Furthermore, a collection plate is fixed on both sides of the mounting base, and the collection plate is located directly below the roller of the roller conveyor.

[0018] By adopting the above technical solution, the collecting plate can collect the coal dust swept by the scraper, thus avoiding waste.

[0019] Furthermore, the scraper is made of antistatic polyurethane material, and the top of the scraper is arc-shaped.

[0020] By adopting the above technical solution, the arc-shaped top of the scraper fits the curved surface of the roller (improving the cleaning effect), and the anti-static material avoids sparks generated by friction.

[0021] Furthermore, the threaded shaft is made of stainless steel and is located inside the first shielding cylinder and the second shielding cylinder.

[0022] By adopting the above technical solution, stainless steel is resistant to coal dust corrosion, and the first and second shielding cylinders wrap around the threaded shaft to achieve full-enclosed protection, thereby improving the protection effect on the threaded shaft.

[0023] Furthermore, both the roller conveyor and the cylinder are electrically connected to an external control panel.

[0024] By adopting the above technical solution, the roller conveyor and cylinder can be started or stopped via an external control panel.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model features a liftable scraper that corresponds one-to-one with the rollers of the roller conveyor. When it is necessary to remove coal dust adhering to the roller surface, the operator can rotate the threaded shaft by turning the knob, causing the threaded shaft to move upward and driving the lifting plate to move upward, which in turn drives the scraper to move upward, so that the arc-shaped top of the scraper fits against the roller surface. As the roller rotates, the scraper can remove the residual coal dust, avoiding slippage and deviation caused by coal dust accumulation, thus improving the conveying effect of the roller conveyor. This method can also clean multiple rollers simultaneously, eliminating the need to clean the roller surface one by one, thereby simplifying the cleaning process and improving the cleaning efficiency of the roller surface. When it is not necessary to clean the coal dust adhering to the roller surface, the operator can rotate the threaded shaft in the opposite direction, causing the lifting plate to move downward and driving the scraper to move downward. The scraper is no longer in contact with the roller surface, avoiding continuous friction between the rotating roller and the scraper, thereby extending the service life of the scraper.

[0027] 2. This utility model is equipped with a first shielding cylinder and a second shielding cylinder, which can form a complete enclosure for the threaded shaft, preventing dust from adhering to the threaded shaft, ensuring that the threaded shaft can rotate smoothly and achieve lifting and lowering. In addition, the anti-static polyurethane material (scraper, first shielding cylinder and second shielding cylinder) releases static electricity, avoids sparks, and meets the coal powder explosion-proof safety standards.

[0028] 3. This utility model has a collection plate that collects the swept coal dust, which can be recycled and reused, reducing coal dust waste and reducing the amount of floor cleaning work. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of this utility model will be described below based on its overall structure.

[0039] Example 1:

[0040] A feeding device for a coal powder sealed coal bucket, such as Figures 1-7 As shown, the equipment includes a coal powder packaging device 1 and two roller conveyors 2. The roller conveyors 2 serve as the conveying carriers for coal buckets. Coal buckets to be packaged with coal powder enter the equipment from one roller conveyor 2, while the other roller conveyor 2 transfers coal buckets filled with coal powder from the packaging equipment to the next stage (such as storage). The coal powder packaging device 1 has an installation frame 3 installed inside, and a cylinder 4 is installed on the installation frame 3. The output end of the cylinder 4 is connected to a push plate 5 through a piston rod. A fixing frame 6 is fixed at the bottom of the roller conveyor 2, and a threaded shaft 7 is threadedly connected to the bottom of the fixing frame 6. A lifting plate 12 is connected to the top of the threaded shaft 7 through a bearing. Multiple mounting seats 14 are installed on the top of the lifting plate 12, and a scraper 13 is provided on the top of the mounting seats 14. The scraper 13 and the mounting seats 14 are detachably connected to the lifting plate 12. A knob 8 is installed at the bottom of the threaded shaft 7. The outer wall of the knob 8 is provided with anti-slip texture, which makes it convenient for the operator to rotate the threaded shaft 7 through the knob 8, thereby enabling the threaded shaft 7 to be raised and lowered.

[0041] See Figures 1-6The number of scrapers 13 is the same as the number of rollers in the roller conveyor 2. Each scraper 13 corresponds to a roller, ensuring that each roller has its own dedicated scraper 13 to avoid missed cleaning. Both sides of the mounting base 14 are fixed with collecting plates 15, which are located directly below the rollers of the roller conveyor 2. The collecting plates 15 can collect the coal dust cleaned by the scrapers 13 to avoid waste. The threaded shaft 7 is made of stainless steel and is located inside the first shielding cylinder 9 and the second shielding cylinder 10. Stainless steel is resistant to coal dust corrosion. The first shielding cylinder 9 and the second shielding cylinder 10 enclose the threaded shaft 7 to achieve full-enclosed protection, thereby improving the protection effect of the threaded shaft 7. The roller conveyor 2 and the cylinder 4 are electrically connected to the external control panel so that the roller conveyor 2 and the cylinder 4 can be started or stopped through the external control panel.

[0042] Example 2:

[0043] Based on the above embodiment 1, in order to improve the protection effect on the threaded shaft 7, the following structure will be set.

[0044] Specifically, a second shielding cylinder 10 is provided between the bottom of the lifting plate 12 and the fixed frame 6. The second shielding cylinder 10 is made of anti-static polyurethane material. A first shielding cylinder 9 is installed at the bottom of the fixed frame 6. The first shielding cylinder 9 is also made of anti-static polyurethane material. The bottom of the first shielding cylinder 9 is tightly fitted to the top of the knob 8. The first shielding cylinder 9 blocks coal dust from entering the lower gap of the threaded shaft 7, protecting the threaded shaft 7 from dust corrosion. The anti-static polyurethane material releases static electricity to prevent sparks. The second shielding cylinder 10 can shield the upper part of the threaded shaft 7, thus forming a double protection with the first shielding cylinder 9.

[0045] Example 3:

[0046] Based on the above embodiment 1, in order to avoid sparks generated by friction between the scraper 13 and the roller, the scraper 13 will be made of the following materials.

[0047] Specifically, the scraper 13 is made of antistatic polyurethane material. The top of the scraper 13 is arc-shaped and conforms to the curved surface of the roller (to improve the cleaning effect). The antistatic material avoids sparks generated by friction.

[0048] Example 4:

[0049] Based on the above embodiment 1, the following structure will be set to improve the stability of the lifting plate 12 when it moves.

[0050] Specifically, multiple telescopic rods 11 are installed at equal intervals between the lifting plate 12 and the fixed frame 6. The setting of the telescopic rods 11 restricts the movement direction of the lifting plate 12, avoids tilting during lifting, and ensures that the scraper 13 and the roller are always parallel and in contact.

[0051] The working principle of this utility model is as follows: First, bulk coal powder is quantitatively packaged in the coal powder packaging equipment 1 to form a full coal bucket to be transported. The external control panel sends a signal to the cylinder 4. The cylinder 4 drives the push plate 5 to move horizontally through the piston rod, and pushes the full coal bucket in the packaging equipment smoothly onto the conveying surface of the roller conveyor 2. The external control panel starts the roller conveyor 2 at the same time. The roller rotates and drives the full coal bucket to be transported to the subsequent links (such as the storage area).

[0052] During the conveying process, the arc-shaped top of the scraper 13 fits against the surface of the roller and removes residual coal powder as the roller rotates; the swept coal powder falls onto the collecting plate 15 and is collected and reused. If it is necessary to disassemble the scraper 13 and the collecting plate 15, the workers can unscrew the bolts on the mounting base 14 and then remove the mounting base 14, the scraper 13 and the collecting plate 15.

[0053] When it is necessary to scrape off the coal dust adhering to the roller surface, the operator can rotate the threaded shaft 7 by knob 8, causing the threaded shaft 7 to move upward and drive the lifting plate 12 to move upward, which in turn drives the scraper 13 to move upward, so that the arc-shaped top of the scraper 13 fits against the roller surface. As the roller rotates, the scraper 13 can remove the residual coal dust, avoiding slippage and displacement caused by coal dust accumulation. When it is not necessary to clean the coal dust adhering to the roller surface, the operator can rotate the threaded shaft 7 in the opposite direction, causing the lifting plate 12 to move downward and drive the scraper 13 to move downward. The scraper 13 no longer fits against the roller surface, avoiding continuous friction between the rotating roller and the scraper 13, thereby extending the service life of the scraper 13. Throughout the process, the first shielding cylinder 9 covers the lower part of the threaded shaft 7, and the second shielding cylinder 10 covers the upper part of the threaded shaft 7 to prevent coal dust from adhering to the surface of the threaded shaft 7. At the same time, the anti-static polyurethane material of the scraper 13, the first shielding cylinder 9, and the second shielding cylinder 10 releases static electricity in real time to prevent the generation of sparks.
