Description

Technical Field

[0001] This utility model relates to the field of powder material conveying equipment, and in particular to a glass powder vacuum feeder with an anti-clogging suction structure. Background Technology

[0002] Vacuum feeders are automated equipment that uses negative pressure airflow to transport powdery or granular materials. They are widely used in the chemical, food, and new materials industries. The basic structure includes an air pump that generates negative pressure, a separation chamber for material separation, and a filter device installed in the air path.

[0003] When conveying fine powders such as glass powder, due to the electrostatic adsorption properties of the material itself and its sensitivity to trace amounts of moisture in the environment, the powder particles will adhere tightly to the surface of the filter device. As working time accumulates, the adhered powder layer will gradually thicken, eventually forming a blockage.

[0004] To address clogging in filter devices, current technologies generally employ backflushing systems. These systems use a burst of high-pressure airflow to reverse-force the filter and blow off the adhered material layer. However, for glass powder with strong adhesion, the impact force of a single airflow is limited and cannot completely remove the tightly bonded powder layer. Some material always remains, resulting in poor cleaning performance and the filter's permeability not being fully restored. This incomplete cleaning method causes the clogging of the filter to worsen with repeated use, ultimately leading to a significant decrease in the equipment's material suction capacity, impacting production efficiency. Furthermore, it necessitates frequent shutdowns for manual disassembly and deep cleaning, increasing maintenance costs and labor intensity.

[0005] Therefore, this utility model proposes a glass powder vacuum feeder with an anti-clogging suction structure to overcome the shortcomings of the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a glass powder vacuum feeder with an anti-clogging suction structure, which aims to solve the technical problems of the existing filter device having a single cleaning method and incomplete cleaning of powders with strong adhesion, resulting in a decrease in suction efficiency.

[0007] To achieve the above objectives, the glass powder vacuum feeder with an anti-clogging suction structure provided in this utility model embodiment includes: a separation chamber, a small air hole opened at the top of the separation chamber, an air pipe communicating with the separation chamber, an air pump installed at the end of the air pipe, a filter layer fixed inside the air pipe, a material pipe communicating with the separation chamber, and an anti-clogging mechanism.

[0008] The anti-blocking mechanism includes a cylinder, piston, hollow rod, connecting pipe, support frame, rotating rod, turbine fan, and scraper.

[0009] Furthermore, the cylinder is fixed to the top of the separation chamber, and the output end of the cylinder is fixedly connected to the piston. The outside of the piston is slidably connected to the inside of the hollow rod. The hollow rod is connected to the top of the air pipe through a connecting pipe. The support frame is fixed inside the connecting pipe. A rotating rod is rotatably connected inside the support frame. Multiple turbine fans are fixedly connected to the top of the rotating rod, and multiple scrapers are fixedly connected to the bottom of the rotating rod. The scrapers are combined in a way that maintains an adjustable gap or contact with the bottom surface of the filter layer for scraping.

[0010] Preferably, a fan blade is rotatably connected to the left end of the inner wall of the material pipe, and a motor is fixedly connected to the left end of the outer wall of the material pipe. The output end of the motor is fixedly connected to the left side of the fan blade, which is used for pre-dispersion before the material enters.

[0011] Preferably, the glass powder vacuum feeder with anti-clogging suction structure further includes a hollow block, a collection box, and a rotating cover. The bottom of the separation chamber is connected to the top of the hollow block, the bottom of the hollow block is connected to the top of the collection box, the rotating cover is rotatably connected to the top of the inner wall of the hollow block, and a motor for driving the rotating cover is fixedly connected to the top of the front side of the hollow block to achieve automatic unloading.

[0012] Preferably, the piston slides axially on the inner wall of the hollow rod, the cylinder drives the piston to move, and the resulting airflow rushes towards the filter layer through the connecting pipe and the air pipe.

[0013] Preferably, the turbofan rotates synchronously with the scraper blades under the propulsion of the airflow generated by the cylinder, thereby achieving mechanical scraping.

[0014] Preferably, the outer side of the support frame is fixedly connected to the inner wall of the connecting pipe to provide stable rotational support for the rotating rod.

[0015] Preferably, the outer bottom end of the rotating rod is rotatably connected to the inner wall of the filter layer to ensure that the scraper can rotate stably around the center of the filter layer.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting an anti-clogging mechanism, uses the pulsed airflow generated by the cylinder to impact the filter layer, and simultaneously drives the turbine fan to rotate the scraper to scrape the filter layer. This solves the problem in the prior art where the filter layer is clogged by powder, and the single back-blowing method is not thorough in cleaning, resulting in a decrease in material suction efficiency and the need for manual cleaning after machine shutdown. It achieves the synergistic effect of airflow blowing and mechanical scraping, and performs double and thorough cleaning of the filter layer. This ensures the long-term stability and high efficiency of the equipment's material suction function and improves the level of automation.

[0017] 2. This utility model solves the problem of glass powder and other materials agglomerating due to moisture or static electricity, causing blockages at the suction inlet and affecting the smooth flow of materials, by installing motor-driven fan blades inside the material pipe. It forcibly disperses the materials before they enter the system, preventing blockages at the source, ensuring smooth suction, and reducing the burden on subsequent filter layers.

[0025] Please refer to Figures 1 to 5 This utility model provides a glass powder vacuum feeder with an anti-clogging suction structure, including a separation chamber 1. A small air hole is provided on the top left side of the separation chamber 1. An air pipe 6, which serves as an air extraction channel, is connected to the right side of the separation chamber 1. An air pump 8, which serves as a power source, is provided at the bottom end of the air pipe 6. A filter layer 7, which is used to achieve gas-solid separation, is fixedly connected to the right end of the inner wall of the air pipe 6. A material pipe 3, which serves as a material inlet, is connected to the left side of the separation chamber 1. The air pump 8 extracts the air inside the separation chamber 1 through the air pipe 6 to form a negative pressure environment, thereby sucking the material from the material pipe 3 into the separation chamber 1.

[0026] The inner wall of the material pipe 3 is rotatably connected to the left end of a fan blade 5 for pre-dispersing the incoming material. The outer wall of the material pipe 3 is fixedly connected to the left end of a motor that drives the fan blade 5 to rotate. The output end of the motor is fixedly connected to the left side of the fan blade 5. The bottom end of the separation chamber 1 is connected to the top of the hollow block 9. The bottom of the hollow block 9 is connected to the top of the collection box 10 for final material storage. The inner wall of the hollow block 9 is rotatably connected to a rotating cover 4 that controls the opening and closing of the bottom of the separation chamber 1. The front top of the hollow block 9 is fixedly connected to a motor that drives the rotating cover 4 to rotate. The output end of the motor is fixedly connected to the right front end of the rotating cover 4.

[0027] Please refer to Figure 2 , Figure 3 and Figure 5 The anti-clogging mechanism 2 includes a cylinder 201, which serves as a pulse airflow generator. The bottom of the cylinder 201 is fixed to the top left end of the separation chamber 1. The output end of the cylinder 201 is fixedly connected to the left end of the piston 202. The outer wall of the piston 202 and the inner wall of the hollow rod 203 form a sliding fit. Driven by the cylinder 201, the piston 202 can slide rapidly along the axial direction on the inner wall of the hollow rod 203, thereby pushing air to form a high-pressure pulse airflow. The bottom right end of the hollow rod 203 is connected to the top end of the connecting pipe 204, which serves as an airflow channel. The bottom end of the connecting pipe 204 is connected to the top left end of the air pipe 6, so as to accurately guide the pulse airflow generated by the cylinder 201 to the bottom of the filter layer 7.

[0028] The anti-clogging mechanism 2 also includes a rotating rod 206, a turbine fan 207, and a scraper 208 as mechanical cleaning components. A support frame 205 for supporting the mechanical cleaning components is fixedly connected to the inner wall of the connecting pipe 204. The outer wall of the support frame 205 is fixedly connected to the inner wall of the connecting pipe 204. The inner wall of the support frame 205 is rotatably connected to the outer wall of the rotating rod 206. Multiple turbine fans 207 are fixedly connected to the top of the outer wall of the rotating rod 206. The bottom of the outer wall of the rotating rod 206 is rotatably connected to the inner wall of the filter layer 7. Multiple scrapers 208 are fixedly connected to the bottom of the rotating rod 206. The scrapers 208 maintain an adjustable gap or contact with the bottom surface of the filter layer 7 for scraping, ensuring that while the piston 202 pushes the air to form an airflow, the airflow will drive the turbine fan 207 and the scraper 208 to rotate synchronously, thereby achieving a dual cleaning effect of airflow blowing and scraping by the scraper 208, which greatly improves the cleaning efficiency and thoroughness of the filter layer 7.

[0029] As a preferred embodiment, in order to effectively disperse the material before it enters the separation chamber 1 and prevent agglomeration caused by moisture or static electricity from clogging the pipes, please refer to... Figure 1 and Figure 2The inner left end of the material pipe 3 is rotatably connected to a fan blade 5, while the outer left end of the material pipe 3 is fixedly connected to a drive motor. The output end of the motor is fixedly connected to the left side of the fan blade 5 through a coupling or directly, thereby driving the fan blade 5 to rotate at high speed inside the material pipe 3.

[0030] As another preferred embodiment, in order to achieve automatic switching between the feeding and unloading processes and reliably maintain the negative pressure environment inside the separation chamber 1, please refer to... Figure 1 and Figure 4 The bottom of the separation chamber 1 is connected to the top of the hollow block 9 by a flange connection or integral molding. The bottom of the hollow block 9 is connected to the top of the collection box 10. A rotating cover 4 that can seal the bottom opening of the separation chamber 1 is rotatably connected to the top of the inner wall of the hollow block 9. To realize the automatic opening and closing of the rotating cover 4, a motor is fixedly connected to the top of the front side of the hollow block 9. The output end of the motor is fixedly connected to the front right side of the rotating cover 4.

[0031] As another preferred embodiment, to ensure that the pulsed airflow generated by the anti-clogging mechanism 2 can act on the filter layer 7 efficiently and without leakage, please refer to... Figure 3 and Figure 5 A sealing ring can be provided on the outer periphery of the piston 202 to ensure good airtightness when the piston 202 slides axially on the inner wall of the hollow rod 203. At the same time, the bottom right end of the hollow rod 203 is connected to the top end of the connecting pipe 204 by welding or threading. The bottom end of the connecting pipe 204 is also connected to the top left end of the air pipe 6 by welding or threading, forming a complete backflush air path.

[0032] As another preferred embodiment, to ensure the stable operation of the mechanical cleaning components, please refer to... Figure 3 The outer side of the support frame 205 is fixedly connected to the inner wall of the connecting pipe 204 by welding or interference fit, providing a solid foundation for the stable rotation of the rotating rod 206. At the same time, the bottom end of the outer wall of the rotating rod 206 is rotatably connected to the center position of the inner wall of the filter layer 7, ensuring that the scraper 208 can rotate stably around the center and achieve full coverage of the bottom surface of the filter layer 7.

[0033] Working principle: During the feeding stage, the motor driving the rotating cover 4 is not working, and the rotating cover 4 remains closed. The air pump 8 starts and extracts the air from the separation chamber 1 through the air pipe 6. Since the top left side of the separation chamber 1 has a small air hole for air replenishment and balance, a stable negative pressure is formed inside the separation chamber 1. The glass powder material from the outside is sucked in through the material pipe 3 under the action of atmospheric pressure difference. At the same time as entering the material pipe 3, the motor driving the fan blade 5 starts and drives the fan blade 5 to rotate at high speed, forcibly breaking up any materials that may clump together. After the broken material enters the separation chamber 1 with the airflow, it begins to fall due to gravity, while the air continues to be extracted by the air pump 8 through the filter layer 7. The glass powder is effectively intercepted by the filter layer 7 and accumulates above the rotating cover 4, completing the separation of material and air. When unloading, the air pump 8 stops working, the motor driving the rotating cover 4 starts, and the rotating cover 4 opens. The material falls into the collection box 10 below through the hollow block 9. During the cleaning phase, when the suction of filter layer 7 decreases due to excessive powder adhering to its surface after prolonged operation, the anti-clogging mechanism 2 activates. Cylinder 201 actuates instantaneously, rapidly pushing piston 202 to slide axially within hollow rod 203, generating a powerful pulsed airflow. This airflow, passing through the top of connecting pipe 204 and air pipe 6, impacts the bottom surface of filter layer 7, directly blowing off most of the adhering powder. Simultaneously, this high-speed airflow drives multiple turbine fans 207 inside connecting pipe 204 to rotate at high speed. Since the turbine fans 207 and scraper blades 208 are fixedly connected and rotate synchronously via rotating rod 206, the rotating scraper blades 208 mechanically scrape away stubborn deposits that are difficult for the airflow to remove. This solves the problem of easy clogging and difficult cleaning of existing filter devices, ensuring long-term, efficient, and stable operation of the equipment. The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
