Description

Technical Field

[0001] This utility model relates to the field of screw conveyor technology, specifically to a screw conveyor for powdery materials with an inclined angle. Background Technology

[0002] When a screw conveyor is used for conveying powder, its inlet and outlet ports must be sealed to the feeding and receiving equipment to prevent leakage of powder during transmission and avoid dust pollution.

[0003] To further enhance the adaptability and flexibility of the equipment, especially when handling material conveying tasks with different horizontal or vertical height differences, existing screw conveyors are typically equipped with adjustable supports underneath. These supports include two hinge points and a lifting mechanism between themselves and the conveyor drum. For example, Chinese Utility Model Patent Application No. CN202222454040.6 discloses a screw conveyor turning connector. While this allows operators to adjust the conveyor's tilt angle according to specific needs, the structure is relatively complex and occupies a large space.

[0004] Therefore, it is necessary to propose an inclined screw conveyor for powdery materials to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1-5 As shown, an inclined screw conveyor for powdery materials includes a conveying cylinder 3. The two ends of the conveying cylinder 3 are respectively provided with an inlet and an outlet. A conveying pipe 2 is fixedly connected to both the inlet and outlet of the conveying cylinder 3. A connecting assembly 4 is fixedly connected to the conveying pipe 2. The connecting assembly 4 includes two flanges 8. An elastic telescopic cover 9 is connected between the two flanges 8. A support column 12 is fixedly connected to one side of each of the two flanges 8. The ends of the two adjacent support columns 12 away from the flanges 8 are rotatably connected.

[0028] By setting connecting components 4 at both the inlet and outlet of the conveying cylinder 3, it can adapt to material conveying at different inclination angles. During the connection process, after adjusting the feeding equipment and the material receiving equipment to a suitable distance, the inlet and outlet of the conveying cylinder 3 are connected to the feeding equipment and the material receiving equipment respectively through the connecting components 4. After the connection is fixed, the conveying cylinder 3 is supported and limited under the support of the support column 12, so that it does not need to be supported by a complex size structure, thus simplifying the support structure.

[0029] Specifically, the axes of the two conveying pipes 2 are parallel to each other; the end of the conveying pipe 2 away from the conveying cylinder 3 is fixedly connected to the flange 8 by bolts. By using bolts to fix the flange 8 to the conveying pipe 2, it is possible to disassemble and maintain the connecting assembly 4.

[0030] Specifically, each flange 8 is fixedly connected to two supports 12, which are symmetrically distributed along the axis of the conveying cylinder 3. By hinged the supports 12 on the two flanges 8, the flanges 8 can rotate with the tilt angle of the conveying cylinder 3, so that they can be used for conveying materials at different tilt angles.

[0031] In some embodiments, a limiting ring 10 is fixedly connected to one side of the flange 8, and the elastic telescopic cover 9 is fixedly connected to the flange 8 via a clamp 11. By using the cooperation of the limiting ring 10 and the clamp 11 to fix the end of the elastic telescopic cover 9 to the flange 8, the connection is made more secure, while also facilitating the disassembly and replacement of the elastic telescopic cover 9.

[0032] Specifically, a rotating shaft 6 driven by a motor 1 is rotatably connected inside the feeding cylinder 3, and a spiral blade 5 is fixedly connected to the outside of the rotating shaft 6.

[0033] During material conveying, motor 1 is started, and material enters the conveying cylinder 3 through the feed inlet from the feeding device. Motor 1 drives the spiral blades 5 to rotate via the rotating shaft 6. Under the action of the spiral blades 5, the material in the conveying cylinder 3 is pushed from the feed inlet to the discharge outlet, and the material is finally discharged from the discharge outlet into the material-using equipment. Preferably, both ends of the rotating shaft 6 are rotatably connected to the conveying cylinder 3 through two relatively arranged conical bearings. The two conical bearings jointly support the rotating shaft 6, enhancing its load-bearing capacity, preventing the shaft center of the rotating shaft 6 from shifting, and ensuring its stable operation.

[0034] In some embodiments, a bracket 7 is rotatably connected to the lower center of the feed cylinder 3. The bracket 7 provides auxiliary support to the feed cylinder 3, thereby improving its stability.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
