Description

Technical Field

[0001] This utility model relates to the field of vacuum feeding technology, and in particular to an anti-clogging vacuum feeding device. Background Technology

[0002] A vacuum conveyor is a device that uses the principle of vacuum negative pressure to suck up and transport powdery, granular, or small lump materials to a designated location through pipelines. It is widely used in the pharmaceutical, food, and chemical industries, and is particularly suitable for material conveying in closed, dust-free environments. Its core components include a vacuum pump, hopper, conveying pipeline, and control system, enabling efficient, environmentally friendly, and safe material handling.

[0003] If the humidity is too high during the storage of powder, it will cause the powder to clump together. When the powder is vacuum-fed, it is very easy to cause blockage inside the feeding device, making it difficult for the feeding device to carry out normal powder conveying work.

The feed tank 4 is used for stirring and scraping powder to prevent clogging caused by powder accumulation, thus improving suction stability. A drive assembly is installed on the surface of the storage tank 4, and a feeding and crushing mechanism is installed inside. This mechanism consists of a crushing box 17, a drive motor 18, a crushing roller 19, a transmission gear 20, and a suction pipe 21. The crushing box 17 is rectangular and made of metal. Metal crushing boxes are stronger, less prone to deformation and damage under stress, and more durable. The discharge end of the crushing box 17 is connected to the storage tank... The inner wall of the tank 4 is fixedly connected, the drive motor 18 is fixedly connected to the front of the crushing box 17, and the output end of the drive motor 18 is rotatably connected to the inner wall of the crushing box 17. The crushing roller 19 is rotatably connected to the inner wall of the crushing box 17, and the crushing roller 19 is fixedly connected to the output end of the drive motor 18. The inner wall of the transmission gear 20 is fixedly connected to the surface of the crushing roller 19.

[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0025] In use: First, start the vacuum pump 7 to draw air from the storage tank 4 through the air duct 6. After the storage tank 4 is under negative pressure, the powder inside the storage tank 2 is drawn in through the crushing box 17 and the suction pipe 21. Start the drive motor 18 to drive the crushing roller 19 and the transmission gear 20 to rotate. Through the meshing of multiple transmission gears 20, multiple crushing rollers 19 are driven to rotate relative to each other along the inner wall of the crushing box 17, which can crush the lumps in the powder. After the powder enters the storage tank 4, it is filtered by the filter screen 8 and the filter element 9 to prevent the powder from entering the vacuum pump 7. In the process, the servo motor 14 is started to drive the worm gear 15 to rotate. Through the meshing of the worm gear 15 and the worm wheel 16, the fixed shaft 11 and the inner wall of the fixed frame 10 are driven to rotate. The rotation of the fixed shaft 11 drives the stirring rod 12 and the scraper 13 to rotate. The rotation of the stirring rod 12 stirs the powder to prevent accumulation and blockage. The rotation of the scraper 13 can scrape off the powder adsorbed on the surface of the filter screen plate 8. After the suction and feeding are completed, the air inlet valve 5 is opened to remove the negative pressure state from the storage tank 4. The solenoid valve 22 is opened to transport the powder to the collection bucket 23 to complete the feeding work.

[0026] In summary, this anti-clogging vacuum feeding device, when the vacuum pump 7 is started, draws powder from inside the storage tank 2 through the air duct 6, storage tank 4, and feeding crushing mechanism. Activating the feeding crushing mechanism crushes any lumps in the powder. The filter screen 8 and filter element 9 filter and prevent powder from entering the vacuum pump 7. Activating the drive assembly drives the anti-clogging mechanism to rotate, preventing powder blockage through stirring and scraping actions. Opening the air inlet valve 5 removes the storage tank 4 from the negative pressure state. Activating the discharge assembly delivers the powder to complete the feeding process. This achieves the goal of facilitating the crushing and anti-clogging of powder in the feeding device, avoiding the problem that when the powder is damp and lumps form, the lumps will block the feeding device, preventing it from performing its normal suction and feeding function. This device solves the problems mentioned in the background art.
