Description

Technical Field

[0001] The invention relates to a disc separator device, in particular to a self-vibration-absorbing disc separator drum, belonging to the technical field. Background Art

[0002] As a separation device, the disc separator drives the drum to rotate at high speed through the motor-driven rotor. Under the centrifugal force generated by the high-speed rotation of the mixed liquid in the drum, the heavy phase is settled on the disc and accumulated in the casing by centrifugal force. It is discharged by manual or automatic slag discharge, and the light phase is output through a centripetal pump. This separation equipment for separating solids and liquids or light and heavy phase liquids is widely used in the fields of medicine, food, chemical industry, and shipping due to its powerful separation efficiency.

[0003] At present, the disc separator has a problem of deviation of the center of gravity of the drum due to aging and wear of the drum and bearings, or eccentricity of the internal material during centrifugation, which causes the drum to vibrate during high-speed rotation. This vibration will not only accelerate the wear of parts and reduce their service life, but also cause the equipment to produce large vibration noise. In addition, the vibration of the separator drives the internal liquid and disc to vibrate, and also causes the liquid to generate eddy currents on the surface of the disc, disrupting the stratification of the solid and liquid phases and affecting the separation efficiency of the equipment. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a self-vibration-absorbing disc separator drum, which can reduce the vibration of the disc separator, reduce the noise generated when the separator is working, increase the service life of the equipment, and improve the separation efficiency, thereby overcoming the shortcomings of the prior art.

[0006] As a further technical solution of the present invention, the counterweights are symmetrically arranged on both sides of the drum body, the counterweight boxes on both sides of the drum are provided with counterweight grooves, counterweight rubber pads are placed at the bottom of the counterweight grooves, counterweight shock absorbing rings are sleeved on the outer side of the counterweight core and placed in the counterweight grooves, a counterweight box cover is installed on the top of the counterweight box, a counterweight box gasket is placed between the counterweight box cover and the counterweight box, and the counterweight box and the counterweight box cover are fastened and sealed by four counterweight box screws;

[0007] The drum body is driven to rotate by the transmission shaft at the bottom, and the counterweight moves synchronously with the drum body. The vibration of the drum body is transmitted to the counterweight. The counterweight box gasket and the counterweight rubber pad are compressed when the counterweight core vibrates axially. The counterweight shock-absorbing ring is compressed when the counterweight core vibrates radially.

[0008] Furthermore, the counterweight core is made of lead block material or other materials with higher density.

[0009] Furthermore, the counterweight rubber pad and the counterweight shock-absorbing ring are made of a material with a high elastic coefficient.

[0010] Furthermore, the counterweight shock-absorbing ring and the counterweight core are interference-fitted.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0023] Embodiment 1

[0024] like Figure 1-4 As shown, this embodiment discloses a self-vibration-absorbing disc separator drum, including a drum body 4 and a counterweight body 2 connected to the flange portion of the drum body 4. The drum body 4 is installed on the disc separator and is driven by a transmission shaft 18 to rotate to complete the centrifugal operation of the material.

[0025] In the preferred structural design of this implementation, Figure 2 As shown, it is characterized in that: the counterweight body 2 includes a counterweight box 6, a counterweight 3 composed of a counterweight core 13 and a counterweight shock-absorbing ring 10 installed inside the counterweight box 6, and the top of the counterweight box 6 has a counterweight box cover 15 and a counterweight box gasket 14 and is equipped with four counterweight box screws 16; in this embodiment, an axisymmetric counterweight body 2 is introduced into the drum body 4 to improve the inertia system of the drum, because the larger the mass of the object, the smaller its vibration frequency and amplitude, and the smaller the impact on mechanical equipment. The addition of the counterweight body 2 transfers the main kinetic energy of the drum to the counterweight core 13, and most of the energy generated by the drum during vibration is also transferred to the counterweight body 2.

[0026] Specifically, the counterweight 3 is symmetrically arranged on both sides of the drum body 4, and the counterweight boxes 6 on both sides of the drum are provided with counterweight grooves 7, and counterweight rubber pads 9 are placed at the bottom of the counterweight grooves 7. The counterweight core 13 is sleeved with a counterweight shock-absorbing ring 10 on the outside and placed in the counterweight grooves 7. A counterweight box cover 15 is installed on the upper part of the counterweight box 6, and a counterweight box gasket 14 is padded between the counterweight box cover 15 and the counterweight box 6. The counterweight box 6 and the counterweight box cover 15 are fastened and sealed by four counterweight box screws 16; through the implementation of this solution, the upper, lower and surrounding parts of the counterweight core 13 are respectively wrapped by the counterweight box gasket 14 with a high elastic coefficient, the counterweight rubber pad 9 and the counterweight shock-absorbing ring 10, the vibration generated by the drum is introduced into the counterweight body 2, and the vibration energy is transmitted through the counterweight core 13 and absorbed by the counterweight shock-absorbing ring 10 with a high elastic coefficient, the counterweight box gasket 14 and the counterweight rubber pad 9, so the vibration is greatly reduced.

[0027] The drum body 4 installed in the present application is driven to rotate by the transmission shaft 18 at the bottom, and the counterweight 3 moves synchronously with the drum body 4. When the drum body 4 vibrates, it will be transmitted to the counterweight 3. When the counterweight core 13 vibrates axially, it will compress the counterweight box gasket 14 and the counterweight rubber pad 9. When the counterweight core 13 vibrates radially, it will compress the counterweight shock-absorbing ring 10. The counterweight core 13 is made of high-density materials such as lead blocks, which can reduce the volume occupied by the counterweight 3, and the interference fit between the counterweight core 13 and the counterweight shock-absorbing ring 10 and the counterweight groove 7 can improve the energy transmission efficiency between the various parts of the drum, and improve the shock-absorbing effect of the counterweight core 13.

[0028] Embodiment 2

[0029] In the self-vibration-absorbing disc separator drum installed in the present application, the counterweights 2 are symmetrically arranged on both sides of the drum body 4 with the drum axis as the center plane. The counterweights 5 in the counterweight box 6 can be one, two, four or five. Regardless of the number of counterweights 5, the counterweights 5 on both sides of the drum body 4 are symmetrically distributed with the drum axis as the center. Figure 3 As shown, it is an implementation example in which four counterweights 5 are arranged in the counterweight slot 7 in the second implementation example.

[0030] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any person familiar with the technology can understand and think of any changes or substitutions within the technical scope disclosed by the present invention, which should be included in the scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
