Description

Technical Field

[0001] This utility model relates to the field of screw conveyor technology, specifically a screw conveyor for powder conveying. Background Technology

[0002] A screw conveyor is a machine that uses a motor to drive a screw to rotate and push materials to achieve the function of conveying. It can convey horizontally, inclined or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance and convenient closed transportation. When conveying powder, the motor drives the screw to rotate, and the friction between the blades and the material generates axial thrust, which pushes the powder forward.

[0003] However, since the powder is stored inside the storage bin before being added to the screw conveyor, and the storage bin is designed to be open to facilitate the addition of powder, the powder inside the storage bin is highly susceptible to the influence of ambient humidity. When the humidity in the air is too high, the humid air will come into contact with the powder, easily causing the powder to clump. Clumped powder will block the feed inlet of the screw conveyor during the conveying process, thus affecting the normal operation of the screw conveyor. Furthermore, the powder that has come into contact with humid air will also adhere to the outer wall of the auger inside the screw conveyor during transport. Since the auger is installed inside the screw conveyor and is not easy to clean, it will cause inconvenience to clean the powder adhering to the auger. Utility Model Content

[0018] Please see Figures 1 to 7 A screw conveyor for powder conveying includes a screw conveyor body 1. A feed pipe 2 is fixedly installed at the left end of the screw conveyor body 1. A storage tank 3 is fixedly connected to the end of the feed pipe 2 away from the screw conveyor body 1. A cavity is formed in the inner wall of the storage tank 3, and a heating element is installed in the cavity. A feeding pipe 4 is fixedly connected to the upper left end of the storage tank 3. A rotating shaft 5 is arranged inside the storage tank 3. A first rotating component 6 located inside the feed pipe 2 is fixedly installed at the lower end of the outer wall of the rotating shaft 5.

An operation button 25 is installed on the right side of the front of the control box 15. The heating element is controlled by the operation button 25. At this time, as the temperature of the heating element rises, the heat generated is transferred to the interior of the storage tank 3 through the inner wall of the storage tank 3 and heats the powder in the storage tank 3.

[0021] A disc 16 located below the first rotating component 6 is fixedly installed at the lower end of the rotating shaft 5. Mounting rods 17 are evenly distributed at the lower end of the disc 16. A ball bearing 18 is rotatably connected to the outer wall of the end of the mounting rod 17 away from the disc 16.

A reducer is provided on the output shaft of the drive motor 19. When the power of the drive motor 19 is turned on, the drive motor 19 drives the first rotating component 6 and the second rotating component 7 to rotate inside the storage tank 3 through the rotating shaft 5. The rotation of the first rotating component 6 and the second rotating component 7 will stir the powder in the storage tank 3, which can break up the powder that has become damp and clumped due to environmental influences, and at the same time keep the powder in the storage tank 3 dry. The outer wall of the drive motor 19 is fixedly fitted with a housing 20, and the lower end of the housing 20 is fixedly connected to the upper end face of the can cover 8.

[0022] The first rotating component 6 includes a first annular block 601, a first connecting rod 602 and a first scraper 603.

Due to the bolted connection between the first scraper 603 and the first connecting rod 602, and the bolted connection between the second scraper 703 and the second connecting rod 702, it is convenient to replace the first scraper 603 and the second scraper 703.

[0024] The support assembly 10 includes a support block 101, a slide groove 102, and extension rods 103. Several extension rods 103 are evenly distributed on the outer wall of the support block 101, and the end of the extension rod 103 away from the support block 101 is fixedly connected to the inner wall of the feed pipe 2. The upper end face of the support block 101 is provided with a slide groove 102, and the inner wall of the slide groove 102 is rotatably connected to the outer wall of the ball 18. The opening of the slide groove 102 provides a platform for the rolling of the ball 18, and at the same time strengthens the stability of the rotating shaft 5 rotating in the storage tank 3.

[0025] An upper end plate 22 is fixedly installed at the rear end of the can lid 8. An electric push rod 21 is fixedly installed on the bottom surface of the upper end plate 22 away from the can lid 8. By controlling the power supply of the electric push rod 21, the connection method between the storage tank 3 and the can lid 8 is changed, thereby facilitating the cleaning of the inside of the storage tank 3. The lower end of the electric push rod 21 is fixedly connected to a lower bottom plate 23, and the front end of the lower bottom plate 23 is fixedly connected to the back of the storage tank 3.

[0026] Working principle: In use, firstly, the powder to be conveyed is added into the storage tank 3 through the feeding pipe 4. The temperature and humidity of the powder in the storage tank 3 are monitored by the temperature and humidity sensor 9, and the real-time monitoring data is uploaded to the display screen 24 for display. Since the control box 15 is electrically connected to the heating element and the temperature and humidity sensor 9, when the humidity value of the powder in the storage tank 3 is high, the heating element is controlled by the operation button 25. At this time, as the temperature of the heating element rises, the heat generated is transferred to the interior of the storage tank 3 through the inner wall of the storage tank 3, heating the powder in the storage tank 3. The power of the drive motor 19 is turned on. After the drive motor 19 is turned on, it drives the first rotating component 6 and the second rotating component 7 to rotate inside the storage tank 3 through the rotating shaft 5. The rotation of component 6 and the second rotating component 7 will stir the powder in the storage tank 3, which can break up the powder that has become damp and clumped due to environmental influences, and at the same time keep the powder in the storage tank 3 dry. Then, the power of the screw conveyor body 1 is turned on, so that the powder in the storage tank 3 falls from the feed pipe 2 into the interior of the screw conveyor body 1, realizing the conveying of the powder. Finally, the powder is discharged from the discharge pipe 11. By controlling the power of the electric push rod 21, the connection between the storage tank 3 and the tank cover 8 is changed, which facilitates the cleaning of the inside of the storage tank 3. Since the first scraper 603 is bolted to the first connecting rod 602, and the second scraper 703 is bolted to the second connecting rod 702, it is easy to replace the first scraper 603 and the second scraper 703.
