Description

Technical Field

[0001] This utility model relates to centrifuge support structures, and more particularly to a support structure for centrifuges. Background Technology

[0002] Centrifuges mainly rely on mechanical power to generate centrifugal force to separate solid particles and liquids, or to separate two liquids that are mixed together but have different densities one by one. Centrifuges are widely used in mineral processing, agricultural separation, isotope separation in the chemical industry, or the separation of different components in polymer solutions.

[0003] The prior art patent document CN208642982U provides a support structure for a centrifuge, including a support column for insertion and installation on the centrifuge base. A housing is installed on the support column, and a pad is fixed to the bottom of the housing to contact the ground. A vibration damping structure for reducing vibration is installed at the bottom of the support column. The vibration damping structure is disposed inside the housing. The vibration damping structure includes a main damping spring damper and a secondary damping spring damper. The damping spring damper is vertically disposed between the support column and the pad, and the secondary damping spring damper is inclined around the main damping spring damper. This centrifuge vibration damping support leg has good vibration damping performance, reduces the adverse effects of vibration on the centrifuge, and improves the support stability of the centrifuge.

[0004] Although the device has many beneficial effects, it still has the following problems: the support structure used for centrifuges generates high-frequency vibrations when the centrifuge is running, which affects the operation and can cause the centrifuge to malfunction and be damaged. Therefore, there is no effective shock absorption mechanism to convert and reduce the severe vibrations. Secondly, when the working environment of the centrifuge changes, the required support height of the centrifuge also needs to be changed. Therefore, an adjustable support structure is needed to change the height of the support legs. Utility Model Content

[0021] This utility model provides an overall structural diagram of a support structure for a centrifuge according to one embodiment, including: Please see Figures 1-5 A support structure for a centrifuge according to this embodiment includes: a centrifuge body 1, a shell 2, a support plate 3, a base plate 4, a shock absorption mechanism 100, and a support mechanism 200. The support plate 3 is welded to the lower end of the centrifuge body 1 to support the centrifuge. The shock absorption mechanism 100 is welded to the lower end of the support plate 3 via the first support column 101, and is used to attenuate severe vibrations; The support mechanism 200 is welded to the four corners of the base plate via the base 201, and is used to support the overall weight and actively adjust the level. The outer shell 2 is mounted on the outer end of the shock absorption mechanism 100 and fixed with fixing screws, which serves to protect, prevent dust and improve aesthetics; The base plate 4 is welded to the lower end of the shock absorption mechanism 100 via the sliding column 212. It is the bottom of the support structure and is used to connect the shock absorption mechanism 100 and the support mechanism 200. It is worth noting that, specifically, for the purpose of vibration reduction, the first support column 101 is welded to the four corners of the lower end of the support plate 3 to transfer the load; The first groove 107 opens into the interior of the first support column 101 to provide compression stroke space for the sliding member 102; The lower end of the sliding member 102 is welded to the base plate 4, and the upper end is inserted into the first sliding groove 107 to support and connect the first support column 101. The first damping spring shock absorber 103 is sleeved on the outer circumference of the sliding member 102 and is used to provide shock absorption and cushioning for the centrifuge. The limiting plate 108 is welded to the outer circumference of the lower end of the first support column 101, and a guide hole is provided at its upper end; The guide rod 104 is inserted into the guide hole at the upper end of the limiting plate 108 for limiting and guiding the spring 105; Spring 105 is sleeved on the outer circumference of guide rod 104. It is an auxiliary spring with low stiffness, used to provide preload or absorb minor vibrations. The movable plate 109 is welded to the lower end of the guide rod 104. It has a round hole inside and is fitted onto the outer circumference of the sliding member 102 to limit and guide its movement. The spring placement groove 106 is welded to the upper end of the base plate 4 to prevent the first damping spring shock absorber 103 from shifting.

[0022] Next, in order to support and adjust the centrifuge body 1, specifically, the base 201 is welded to the four corners of the base plate 4. The base 201 has side plates on its side and threaded holes at its lower end. It is installed by welding and can be used to fix and connect the main frame of the support mechanism 200. The threaded rod 206 is sleeved through the threaded hole at the lower end of the base 201. The height of the support foot 209 can be adjusted by rotating the threaded rod 206 to push the limiting member 210. The second helical gear 205 is sleeved on the upper end of the threaded rod 206, and drives the threaded rod 206 through the first helical gear 204 to achieve reciprocating motion; The limiting member 210 is sleeved on the lower end of the threaded rod 206 through an internally embedded rotating wheel. The rotating wheel is to prevent the threaded rod 206 from rotating and causing the limiting member 210 to rotate together. The drive shaft 203 is inserted into the side plate of the base 201 and is used to drive the first helical gear 204. The first helical gear 204 is inserted at the left end of the transmission shaft 203 and is used to drive the second helical gear 205. The sliding column 211 is inserted at the lower end of the base 201 to limit and guide the second support column 207 and prevent misalignment. The second support column 207 is fitted onto the lower end of the sliding column 211 through the third sliding groove 214 opened inside, so as to connect the sliding column 212 through the second sliding groove 214 opened at the lower end of the second support column 207. The second groove 213 is opened on the inner side of the upper end of the second support column 207, providing compression stroke space for the sliding column 211 and the limiting member 210; The rocker arm 202 is inserted at the left end of the drive shaft 203. By rotating the rocker arm 202, the drive shaft 203 is driven to drive the first helical gear 204. The protective cover 215 is fitted onto the outer side of the base 201 to provide protection, dust prevention, and aesthetic appeal.

[0023] Subsequently, in order to dampen the support leg, specifically, the third slide groove 214 is opened on the inner side of the lower end of the second support column 207 to provide compression stroke space for the sliding column 212; The sliding column 212 is inserted into the third sliding groove 214 to limit the second damping spring shock absorber 208; The second damping spring shock absorber 208 is sleeved on the outer ring of the sliding column 212 to absorb and buffer vertical vibration energy. The support foot 209 is welded to the lower end of the sliding column 212, providing a larger force-bearing area for the support mechanism 200.

[0024] Combination Figures 1-5 The specific usage process of a support structure for a centrifuge according to this embodiment is as follows: 1. First, move the centrifuge to the desired position. When the centrifuge vibrates, the vibration is transmitted to the first support column 101 through the support plate 3, thereby pushing the first support column 101 downward along the guide rod 104 to compress the first damping spring shock absorber 103. The first slide groove 107 provides compression stroke space for the sliding member 102 and provides compression and rebound space for the first damping spring shock absorber 103, effectively attenuating the severe vibration, thereby reducing the impact on the work and the occurrence of damage.

[0025] 2. When height adjustment is required, two people need to rotate the rocker arm 202 simultaneously. The initial position of the rocker arm 202 is the lower end of the base 201. One rotation is one cycle. Rotate the required number of cycles as needed, and try to ensure that the rotation speed and number of rotations of the four rocker arms 202 are consistent to avoid jamming. The transmission shaft 203 drives a helical gear through the rocker arm 202, which in turn drives the second helical gear 205 to cause the threaded rod 206 to move axially. Through the limiting member 210, the two support columns 207 are pushed to move the sliding column 211 upward, thereby changing the height of the support mechanism 200. This achieves active adjustment of the level and limiting. At the same time, the second damping spring shock absorber 208 at the lower end provides additional buffering and shock absorption.

[0026] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
