Technical Field
[0001] This utility model relates to the field of material conveying technology, and in particular to a circular tube belt conveyor. 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 purpose 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.
[0003] Existing Chinese patent document CN202021612644.3 relates to the field of conveyors, particularly circular tube belt conveyors. This conveyor includes a frame, a conveying mechanism, a large cyclone spray nozzle, and a filter tube. The conveying mechanism, large cyclone spray nozzle, and filter tube are all fixed to the frame, with the conveying mechanism located inside the filter tube. The outlet of the large cyclone spray nozzle faces the filter tube. This invention, by placing the conveying mechanism inside the filter tube and connecting the filter tube to two workshops, prevents dust leakage during transportation from collection to processing. The cyclone formed by the large cyclone spray nozzle helps improve dust transportation efficiency and can also bring dust falling below the conveying mechanism back onto it.
[0004] However, the above-mentioned patent has certain defects in use. When the screw conveyor is used to transport powdery materials, the poor flowability of the material or the excessive feeding speed can easily cause the feed inlet to become blocked, forming a bridge. After long-term use, the material is easy to stick to the inner wall of the round tube and is difficult to clean. In the end, it is necessary to disassemble and stop the machine for cleaning, resulting in low work efficiency.
[0005] To address these issues, a circular tube belt conveyor is proposed. Utility Model Content

The output end of the speed reducer is equipped with a speed reducer sprocket. The housing 1 contains a conveyor shaft, and the outer peripheral wall of the conveyor shaft is equipped with multiple spiral blades. The conveyor shaft is the core component of the circular tube belt conveyor. It is located inside the housing 1 and has multiple spiral blades on its outer peripheral wall. When the conveyor shaft rotates, the spiral blades push the material from the feed hopper 3 to the discharge port 11 to realize the material conveying. The end of the conveyor shaft near the active end plate is equipped with a conveyor shaft sprocket. The conveyor shaft sprocket and the speed reducer sprocket are connected by a double-row chain.
[0028] The upper surface of the outer shell 1 near the driven end plate is provided with a feed hopper 3, which is connected to the inside of the outer shell 1. The lower surface of the outer shell 1 near the driving end plate is provided with a discharge port 11. An anti-blocking device 8 is provided at the connection between the feed hopper 3 and the outer shell 1. The anti-blocking device 8 is used to clear the material in the feed hopper 3.
[0029] The anti-clogging device 8 includes a handwheel 81, with a handle 82 on one side of the handwheel 81, the handle 82 being fixedly connected to the handwheel 81. A rotating shaft 83 is located at the center of the other side of the handwheel 81, extending into the feed hopper 3 and abutting against the inner wall of the feed hopper 3. Multiple stirring rods 85 are mounted on the rotating shaft 83, and the stirring rods 85 are fixed to the outer peripheral wall of the rotating shaft 83. When it is necessary to clear the material in the feed hopper 3, the operator can rotate the handwheel 81 to drive the rotating shaft 83 to rotate, thereby causing the stirring rods 85 to stir and clear the material.
[0030] The end of the stirring rod 85 is provided with an external thread 86, and the stirring rod 85 is threadedly connected to the rotating shaft 83. This design facilitates the disassembly and replacement of the stirring rod 85.
[0031] Bearings 84 are fitted at both ends of the rotating shaft 83. The bearings 84 are used to reduce frictional resistance during rotation and improve rotational efficiency.
[0032] The upper surface of the outer shell 1 is provided with multiple inspection covers 2. The inspection covers 2 are used to conveniently open or close the conveyor for inspection and maintenance. The inspection covers 2 are fastened to the outer shell 1 by bolts. The inspection covers 2 are provided with handles 21, which are convenient for operators to hold and disassemble and install. The inspection cover 2 at the driven end cover is provided with an inner viewing window 4, which is used to facilitate observation of the internal operation of the equipment.

[0035] A water outlet valve 12 is provided at the bottom of the outer casing 1 near the driven end cap.
[0036] The working principle of this utility model is as follows: In use, the material first enters the conveyor through the feed hopper 3. The feed hopper 3 is connected to the inner shell 1, allowing the material to enter smoothly. When the frequency converter motor 5 starts, it drives the reducer at the active end plate to rotate. The output end of the reducer is equipped with a reducer sprocket, which is connected to the conveyor shaft sprocket on the conveyor shaft through a double-row chain. As the reducer sprocket rotates, the conveyor shaft begins to rotate. Multiple spiral blades are provided on the outer peripheral wall of the conveyor shaft. These spiral blades push the material forward along the inside of the outer shell 1 as the conveyor shaft rotates.
[0037] If the material in the feed hopper 3 becomes clogged, the operator can solve the problem by manually operating the anti-clogging device 8: the operator turns the handwheel 81, the handwheel 81 rotates and drives the rotating shaft 83 to rotate, when the rotating shaft 83 rotates, the stirring rod 85 stirs and clears the material, thereby solving the clogging problem;
[0038] Driven by the conveyor shaft, the material is finally pushed to the discharge port 11 located on the lower surface of the outer shell 1 near the active end plate, thus completing the material conveying process.
[0039] To keep the conveyor clean and running normally, the inspection cover 2 on the upper surface of the outer casing 1 can be opened periodically for cleaning and maintenance. When the equipment needs cleaning, cleaning water can be introduced into the cleaning pipe 7 by opening the valve on the inlet pipe 71 to rinse the inside of the equipment. The wastewater after cleaning is discharged through the outlet valve 12, which facilitates the cleaning and maintenance of the equipment and extends its service life.
