Description

Technical Field

[0001] The utility model belongs to the technical field of horizontal screw centrifuges, and particularly relates to a spiral weight reduction structure of a horizontal screw centrifuge. Background Art

[0002] The horizontal screw screen centrifuge is a horizontal screw unloading, continuously operated filtering equipment. The machine can continuously feed, separate, wash and unload at full speed. It has the characteristics of compact structure, continuous operation, stable operation, strong adaptability, large production capacity and convenient maintenance. It is suitable for separating suspensions containing solid matter with a particle size greater than 0.1mm and a concentration range of 10-90%. It is widely used in chemical, light industry, pharmaceutical, food, environmental protection and other industries.

[0003] The horizontal screw centrifuge is composed of a transmission mechanism, a drum, a spiral body, etc. The spiral body is usually an integral cone-barrel structure with a relatively high overall weight. During long-term operation, the vibration will gradually increase due to the weight of the cone barrel, resulting in a mismatch between the spiral body and the transmission mechanism, causing wear on the cone shaft of the transmission mechanism, which in turn affects the material processing effect and reduces the service life of the equipment.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

Detailed implementation manners

[0024] The following describes the detailed implementation manners of the present utility model in detail, but it should be understood that the protection scope of the present utility model is not limited by the detailed implementation manners.

[0025] The following gives a brief overview of one or more aspects to provide a basic understanding of these aspects. This overview is not an exhaustive survey of all contemplated aspects, and is neither intended to identify key or decisive elements of all aspects nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description to follow.

[0026] Existing spiral bodies, such as Figure 1 shown, are of an integral conical barrel structure with a relatively high overall weight. During long-term operation, due to the weight of the conical barrel, the vibration will gradually increase, so that the situation where the spiral body and the transmission mechanism are not fitted during assembly occurs, causing wear on the tapered shaft of the transmission mechanism, thereby affecting the material handling effect and reducing the service life of the equipment.

[0027] As Figure 1-3 shown, this embodiment provides a spiral weight reduction structure for a horizontal screw centrifuge. The horizontal screw centrifuge includes a transmission shaft 1, a tapered sleeve 2 provided on the transmission shaft 1, and a spiral body 3 fitted with the tapered sleeve 2. A drum 4 is provided outside the spiral body 3. The spiral body 3 includes a plurality of annular supports 5 and ribs 6 connecting the plurality of annular supports 5. The spiral body 3 is integrally in a hollow conical structure. A spiral blade 7 is provided outside the rib 6, and a spiral distribution plate 8 is provided on the annular support 5.

[0028] In this embodiment, as a specific solution, the plurality of annular supports 5 adopt a plurality of flanges with different diameters.

[0029] In this embodiment, as a specific solution, the annular support 5 and the rib 6 are connected by welding.

[0030] In this embodiment, as a specific solution, the spiral blade 7 is welded to the outer wall of the rib 6.

[0031] Principle description: The spiral body 3 is composed of several annular supports 5 and ribs 6 to form a hollow cone structure. On the premise of ensuring the strength of the spiral body, the weight of the spiral body 3 can be effectively reduced, thereby reducing the vibration generated during the operation of the equipment, reducing the wear of the tapered shaft of the transmission mechanism, and extending the service life of the equipment. On the other hand, the hollow structure also makes cleaning more convenient.

[0032] As Figure 4 shown, in another embodiment, as a preferred solution, several groups of plug-in structures 9 adapted to the annular supports 5 are provided on the inner wall of the rib 6.

[0033] More specifically, the plug-in structure 9 includes an upper plug-in block 91 and a lower plug-in block 92, and the gap between the upper plug-in block 91 and the lower plug-in block 92 serves as the plug-in gap 93 of the annular support 5; when the annular support 5 and the rib 6 are assembled, the rib 6 can be clamped onto the annular support 5 through the upper plug-in block 91 and the lower plug-in block 92, enabling quick disassembly and assembly.

[0034] More specifically, the plug-in structure 9 further includes a fastening structure 94 that locks the upper plug-in block 91, the annular support 5, and the lower plug-in block 92; this can improve the connection strength between the annular support 5 and the rib 6, and the fastening structure 94 can adopt fastening bolts, fastening screws, etc.

[0035] As Figure 5-6 shown, in this embodiment, as another preferred solution, the upper plug-in block 91 is an elastic structure, and a convex portion 95 is provided at its end. A limiting cavity 51 is provided above the annular support 5. After the upper plug-in block 91 is inserted into the limiting cavity 51, the convex portion 95 extends outside the limiting cavity 51 to form a limit; similarly, quick disassembly and assembly can be achieved, and the connection strength between the annular support 5 and the rib 6 can be improved without additional fastening structures.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made in accordance with the above teachings.
