Description

Technical Field

[0001] The utility model relates to the technical field of vibration mixer damping equipment, in particular to a composite damping ring at the shaft end of a vibration mixer. Background Art

[0002] A mixer is a machine that mixes materials such as solid particles, solid powders and liquid materials into a uniform mixture. The mixing process is that the mixing shaft drives the mixing arm and mixing blades installed on the mixing shaft to force the materials to mix evenly. The two ends of the mixing shaft extend out of the mixing cylinder and are supported by bearings. A shaft end sealing device is provided between the mixing shaft and the mixing cylinder to prevent leakage of the mixture. The vibrating mixer transmits the vibration to the mixing arm and blades installed on the mixing shaft through the mixing shaft. The mixing arm and the mixing blades generate vibration while forcing the mixing. Vibration and forced mixing make the materials mixed more evenly. The shaft end sealing device is installed on the mixing shaft, and the shaft end sealing device is rigidly connected to the mixing cylinder. The vibration of the mixing shaft causes the seals in the shaft end sealing device to be easily damaged and have a short service life.

[0003] Therefore, there is an urgent need to design a composite damping ring for the shaft end of a vibration mixer to solve the problem that the existing shaft end sealing device is rigidly connected to the mixing cylinder, causing the seal to be damaged and having a short service life. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a composite shock-absorbing ring at the shaft end of a vibration mixer, comprising several compression springs, steel rings arranged on the outside and inside of the compression springs, and composite flexible fillers filled between the inner steel ring, the outer steel ring and the compression spring. This composite flexible filler fixes the outer steel ring, the inner steel ring and the compression spring into one. This composite shock-absorbing ring is arranged between the shaft end sealing device and the mixing cylinder, so that the shaft end sealing device and the mixing cylinder are floatingly connected. When the mixing shaft of the vibration mixer vibrates, this composite shock-absorbing ring will absorb the vibration, protect the seal in the shaft end sealing device, increase the reliability of the shaft end sealing device, and extend the service life of the shaft end sealing device.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a composite shock-absorbing ring at the shaft end of a vibration mixer, comprising an inner ring and an outer ring, a plurality of compression springs are installed between the inner ring and the outer ring, the compression springs are radially compressed between the inner ring and the outer ring, a filler is arranged in the cavity formed between the inner ring and the outer ring, and the filler is distributed on the outside of the compression spring.

[0006] Specifically, the inner ring and the outer ring are both made of steel.

[0007] Specifically, two ends of the compression spring are fixedly mounted on the outer side of the inner ring and the inner side of the outer ring respectively, and the compression springs are evenly and symmetrically arranged around the axis center.

[0008] Specifically, the filler is made of composite flexible material.

[0009] Specifically, the filler, the compression spring, the inner ring and the outer ring form a composite shock-absorbing ring.

[0010] Specifically, the composite damping ring is arranged between the shaft end sealing device of the mixer shaft and the mixing cylinder.

[0011] The utility model has the following beneficial effects:

[0012] The composite damping ring at the shaft end of the vibration mixer designed by the utility model has a simple structure and is easy to manufacture.

[0013] The composite damping ring at the shaft end of the vibration mixer designed by the utility model is arranged between the shaft end sealing device and the mixing cylinder to avoid damage to the sealing component in the shaft end sealing device due to the vibration of the mixing shaft, so that the shaft end sealing device and the mixing cylinder are in a floating connection. When the mixing shaft of the vibration mixer vibrates, the composite damping ring can absorb the vibration, protect the sealing component in the shaft end sealing device, increase the reliability of the shaft end sealing device, and extend the service life of the shaft end sealing device.
