Description

Technical Field

[0001] This utility model relates to the field of sugar production equipment technology, specifically to a centrifuge shock absorber base and an upper-suspended centrifuge body. Background Technology

[0002] Centrifuges are commonly used production equipment in the sugar industry. The top-suspended centrifuge is a common type of centrifuge; its working principle is to separate solid particles from a liquid using centrifugal force. Its main feature is that the liquid sample is placed above the centrifuge rotor, and then the high-speed rotation of the rotor generates centrifugal force, causing solid particles to settle at the bottom. It is often used for the centrifugal separation of molasses.

[0003] In existing top-suspension sugar centrifuges, the shaft is typically connected to a mounting base inside the machine body. During high-speed rotation, uneven distribution of the sugar paste generates vibrations, which are transmitted through the shaft. If this vibration cannot be eliminated promptly, it will affect the operation of the entire machine. Currently, simple rubber pads are used for vibration damping. However, since the rubber pads have a relatively uniform hardness, if they are too hard and rigid, some of the shaft vibration cannot be absorbed by the deformation of the rubber pads, leading to potential shaft damage. Conversely, if the rubber pads are too short, they cannot eliminate the shaft vibration. Therefore, an effective vibration damping mechanism is needed to reduce the centrifuge's vibration. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems mentioned above by providing a centrifuge shock absorber base and a top-suspended centrifuge body, which can reduce the vibration of the top-suspended centrifuge body.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A centrifuge shock absorber includes a rubber seat, several bottom suction cups, and several conical springs. The rubber seat has a connecting groove that extends through the top surface. Several bottom suction cups are located on the side of the rubber seat away from the connecting groove. One conical spring is fixed inside one of the bottom suction cups.

[0006] Furthermore, the rubber seat is provided with a plurality of separation ports extending from the periphery of the rubber seat toward the central axis of the rubber seat, and the plurality of separation ports are distributed in a circumferentially spaced array along the rubber seat.

[0007] Furthermore, the horizontal distance from the periphery of the rubber seat to the central axis of the rubber seat gradually decreases in the direction away from the bottom suction cup.

[0008] A top-suspended centrifuge body includes an outer casing, a support base, a conical nonlinear spring, a motor, a centrifuge drum, a paste extraction tube, a liquid inlet tube, a liquid extraction tube, and the aforementioned centrifuge shock absorber. The outer casing has an installation space, and the support base is located within the installation space and fixed to the bottom of the outer casing. The conical nonlinear spring is fixed within the support base, and the motor is fixed to the top of the outer casing. The motor's shaft extends into the support base and contacts the conical nonlinear spring. The centrifuge drum is located within the installation space. The centrifuge tank is fixedly mounted on the motor shaft. An operating port is provided inside the centrifuge tank, which is opposite to the top surface of the receiving seat. A separation hole is provided through the side wall of the centrifuge tank. The extraction tube extends from the bottom of the centrifuge tank through the operating port to the outside of the outer casing. The liquid inlet tube extends from the outside of the outer casing through the operating port to the inside of the centrifuge tank. The extraction tube is connected to the bottom of the outer casing and communicates with the installation space. The rubber seat is fitted onto the bottom of the outer casing through the fitting groove.

[0009] Furthermore, the centrifuge bucket includes a cylindrical portion and a sloping bottom, the sloping bottom being fixedly mounted on the rotating shaft of the motor, the cylindrical portion being located between the sloping bottom and the top surface of the outer casing; the separation holes are distributed on the side wall of the cylindrical portion; the ointment extraction tube extends into the bottom of the sloping bottom.

[0010] Furthermore, a circular groove plate is fixedly provided at one end of the motor shaft that extends into the receiving seat. A circular groove is recessed on the circular groove plate. One end of the conical nonlinear spring is movably sleeved in the circular groove, and the other end of the conical nonlinear spring is fixed to the receiving seat.

[0011] Furthermore, the top surface of the outer casing is provided with an inverted cone block extending into the installation space, and the diameter of the horizontal cross-section of the inverted cone block gradually decreases towards the receiving seat; the motor is fixed on the inverted cone block and the motor shaft extends through the inverted cone block into the installation space.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects: When using the aforementioned centrifuge vibration damping seat, the bottom of the centrifuge is fitted into the groove. When the centrifuge body vibrates, the rubber material of the seat itself can dampen some of the vibration. When the vibration is transmitted to the conical spring, the spring deforms, further reducing vibration. When the centrifuge vibration damping seat is on a smooth surface, the vibrating centrifuge body can press against the corresponding bottom suction cup, making the seat more stable relative to the ground. Furthermore, the bottom of the motor shaft is connected to the support seat via a conical non-linear spring. The characteristic of this spring is that its stiffness coefficient K increases sharply with increasing compression. This feature allows the motor shaft to have some buffer space to prevent breakage under unbalanced forces during movement, while effectively reducing the movement of the top-suspended centrifuge body under large deformation. Therefore, this invention can reduce the vibration of the top-suspended centrifuge body while preventing the centrifuge drum from impacting the outer casing. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] like Figures 1 to 3 As shown, a preferred embodiment of this utility model provides a centrifuge shock absorber base, including a rubber base 101, a plurality of bottom suction cups 102, and a plurality of conical springs 103. The rubber base 101 is made of rubber, and a sleeve groove 111 penetrating the top surface is provided on the rubber base 101. A plurality of bottom suction cups 102 are provided on the side of the rubber base 101 opposite to the sleeve groove 111, and a conical spring 103 is fixed in one of the bottom suction cups 102.

[0021] When using the above-mentioned centrifuge shock absorber, the bottom of the centrifuge is fitted into the fitting groove 111. When the centrifuge body vibrates, the rubber material of the rubber seat 101 can reduce some of the vibration. When the vibration is transmitted to the conical spring 103, the conical spring 103 deforms, which can further play a role in shock absorption. When the centrifuge shock absorber is on a smooth ground, the vibrating centrifuge body can press against the corresponding bottom suction cup 102, making the rubber seat 101 more stable relative to the ground.

[0022] In this embodiment, a plurality of separation ports 112 are provided through the rubber seat 101. The separation ports 112 extend from the periphery of the rubber seat 101 toward the central axis of the rubber seat 101, and the plurality of separation ports 112 are distributed in a circumferentially spaced array along the rubber seat 101, so that the rubber seat 101 is separated into a plurality of receiving areas. When the centrifuge body vibrates, and the vibration is irregular, the vibration at the strong vibration location can be buffered in the corresponding receiving area.

[0023] In this embodiment, the horizontal distance from the periphery of the rubber seat 101 to the central axis of the rubber seat 101 gradually decreases in the direction away from the bottom suction cup 102. When the rubber seat 101 is fitted onto the centrifuge body, the opening of the fitting groove 111 can be enlarged by prying the periphery of the rubber seat 101 outward in the direction away from the central axis of the rubber seat 101, and then the centrifuge body can be placed and confined therein. This allows the rubber seat 101 to fit onto centrifuge bodies of various sizes.

[0024] This embodiment also provides a top-suspended centrifuge body, including an outer casing 201, a support 202, a conical nonlinear spring 203, a motor 204, a centrifuge drum 205, a paste extraction tube 206, a liquid inlet tube 207, an extraction tube 208, and the aforementioned centrifuge shock-absorbing base. An installation space 211 is provided inside the outer casing 201. The receiving seat 202 is located in the installation space 211 and fixed to the bottom of the outer casing 201. A conical nonlinear spring 203 is fixed inside the receiving seat 202. Specifically, the receiving seat 202 has a concave groove, and the conical nonlinear spring 203 is fixed inside the groove. The motor 204 is fixed to the top of the outer casing 201. The rotating shaft of the motor 204 extends into the groove of the receiving seat 202 and contacts the conical nonlinear spring 203. The centrifuge tank 205 is located in the installation space 211 and is fixedly covered on the rotating shaft of the motor 204. The centrifuge tank 205 has a working port 254 through its interior, away from the top surface of the receiving seat 202. A separation hole 251 is through its side wall. The extraction tube 206 extends from the bottom of the centrifuge tank 205 through the working port 254 to the outside of the outer casing 201. An extraction pump 261 is installed on the extraction tube 206. The liquid inlet tube 207 extends from the outside of the outer casing 201 through the working port 254 to the inside of the centrifuge tank 205. Both the extraction tube 206 and the liquid inlet tube 207 are mounted in the aforementioned positions by an outer frame (not shown in the figure). The extraction tube 208 is connected to the bottom of the outer casing 201 and communicates with the installation space 211. The extraction tube 208 is used to drain the liquid inside the outer casing 201. The rubber seat 101 is fitted onto the bottom of the outer casing 201 through a fitting groove 111.

[0025] Sugarcane juice is introduced into centrifuge tank 205 through inlet pipe 207. Motor 204 starts, and the shaft of motor 204 drives centrifuge tank 205 to rotate axially. The liquid in the sugarcane juice is separated from the separation hole 251 into the installation space 211 and accumulates at the bottom of the outer casing 201. Meanwhile, solid particles in the sugarcane juice continuously accumulate in centrifuge tank 205 to form sugar paste. The sugar paste is finally extracted to the downstream of production through extraction pipe 206 by extraction pump 261. The liquid is discharged from outer casing 201 through extraction pipe 208.

[0026] The bottom of the motor 204's shaft is connected to the support 202 via a conical nonlinear spring 203. The conical nonlinear spring 203 is characterized by a sharp increase in its stiffness coefficient K as the compression increases. This feature allows the motor 204's shaft to have a certain buffer space to prevent breakage when subjected to unbalanced forces during operation, while effectively reducing the movement of the top-suspended centrifuge body under conditions of large deformation. Therefore, this invention can reduce the vibration of the top-suspended centrifuge body while preventing the centrifuge drum 205 from impacting the outer casing 201.

[0027] In this embodiment, the centrifuge tank 205 includes a cylindrical portion 252 and a sloping bottom 253. The sloping bottom 253 is fixedly mounted on the rotating shaft of the motor 204. The cylindrical portion 252 is located between the sloping bottom 253 and the top surface of the outer casing 201. Separation holes 251 are distributed on the side wall of the cylindrical portion 252. The extraction tube 206 extends into the bottom of the sloping bottom 253. The aforementioned structure allows the sugar paste to be more concentrated in the sloping bottom 253, making it easier for the extraction tube 206 to extract the sugar paste in a timely manner.

[0028] In this embodiment, a circular groove plate 209 is fixedly provided at one end of the motor 204 shaft that extends into the receiving seat 202. A circular groove 291 is recessed on the circular groove plate 209. One end of the conical nonlinear spring 203 is movably sleeved in the circular groove 291, and the other end of the conical nonlinear spring 203 is fixed to the receiving seat 202. The aforementioned design ensures that the conical nonlinear spring 203 does not rotate with the rotation of the motor 204 shaft.

[0029] In this embodiment, an inverted conical block 212 extending into the mounting space 211 is mounted on the top surface of the outer casing 201. The diameter of the horizontal cross-section of the inverted conical block 212 gradually decreases towards the receiving seat 202, so as to form clearance space on both sides of the inverted conical block 212 for the ointment tube 206 to pass into the working port 254 of the liquid inlet tube 207. The motor 204 is fixed on the inverted conical block 212, and the rotating shaft of the motor 204 extends through the inverted conical block 212 into the mounting space 211.
