[0038] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.
[0039] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0040] This utility model embodiment provides a high-temperature centrifuge base, such as Figs. 1 to 4 As shown, the high-temperature centrifuge base includes: a first support 1 and a second support 2 that are independent of each other.
[0041] The first support 1 is connected to the centrifuge base 3 at the bottom of the centrifuge body and is used to support the centrifuge base 3.
[0042] The second support 2 is connected to the centrifuge side wall 4 on the side of the centrifuge body and is used to support the centrifuge side wall 4.
[0043] The centrifuge base 3 is flexibly and sealed to the bottom of the centrifuge side wall 4 along the circumference. The vibration transmission between them is small, and they are both interconnected and independent.
[0044] Preferably, the centrifugal spindle 5 is vertically mounted on the first support 1 and the centrifuge base 3, and can rotate relative to the first support 1 and the centrifuge base 3. The lower end of the centrifugal spindle 5 is connected to the centrifugal drive component 7 outside the centrifuge body, and the upper end is connected to the rotating drum inside the centrifuge chamber of the centrifuge body to transmit centrifugal driving force. Heating components, temperature detectors, etc. are installed on the side wall 4 of the centrifuge. During the operation of the centrifuge, the vibration is mainly generated by the centrifugal spindle 5. By setting the heating components and temperature detectors on the side wall 4 of the centrifuge, and by making the side wall 4 of the centrifuge and the centrifuge base 3 a flexible sealed connection, the vibration of the centrifugal spindle 5 on the heating components and temperature detectors is minimized, which can effectively extend the service life of the heating components and temperature detectors.
[0045] Furthermore, the heating component is an electric heating component, including an electric heating wire 41. Preferably, the electric heating wire 41 is installed on the side of the centrifuge sidewall 4 facing the centrifuge chamber, that is, the electric heating wire 41 is directly located inside the centrifuge chamber. While ensuring that the centrifuge sidewall 4 is minimally affected by vibration, installing the electric heating wire 41 on the sidewall of the centrifuge sidewall 4 facing the centrifuge chamber can effectively improve heating efficiency, increase heating speed, and improve thermal energy utilization. Moreover, the electric heating wire 41 is easy to inspect and maintain.
[0046] In one embodiment, both the centrifuge base 3 and the centrifuge sidewall 4 are provided with thermal insulation material layers to provide thermal insulation; at the same time, the periphery of the centrifuge base 3 and the bottom of the centrifuge sidewall 4 are flexibly and sealed through the thermal insulation material layers. This ensures the sealing and continuity of the connection while providing a flexible buffering effect, effectively preventing or mitigating the transmission of vibrations from the centrifuge base 3 to the centrifuge sidewall 4.
[0047] In one embodiment, the first support 1 includes a plurality of first legs 11 and a first platform 12 mounted on the plurality of first legs 11. The centrifuge base 3 is mounted on the first platform 12, and the centrifuge spindle 5 passes through the first platform 12. The first support 1 provides support for the centrifuge base 3 and provides an overhead mounting connection position for the centrifuge drive component 7 and the centrifuge spindle 5.
[0048] The second support 2 includes several second legs 21 and a second platform 22 mounted on the second legs 21. The second legs 21 pass through through holes in the first platform 12 and connect to the second platform 22 above the first platform 12; that is, the second platform 22 is located above the first platform 12. The second legs 21 do not contact the first platform 12 when passing through it. The second platform 22 is an annular platform, adapted to the centrifuge base 3 and the centrifuge sidewall 4. The centrifuge sidewall 4 is mounted on the second platform 22, providing support for the centrifuge sidewall 4.
[0049] The first support 1 and the second support 2 have simple structures and can respectively support and bear the load of the centrifuge base 3 and the centrifuge side wall 4. They are relatively independent of each other and do not generate vibration interference.
[0050] In a further embodiment, a base plate 6 is horizontally disposed at the bottom, and the bottoms of several first legs 11 and several second legs 21 are all mounted on the base plate 6. A buffer pad 61 is provided between the first legs 11 and / or the second legs 21 and the base plate 6. Preferably, the buffer pad 61 is provided between the second legs 21 and the base plate 6. The base plate 6 enables the centrifuge to be skid-mounted as a whole, stabilizing the relative position between the centrifuge base 3 and the centrifuge sidewall 4, and facilitating centrifuge installation. The buffer pad 61 prevents vibration interference between the first support 1 and the second support 2.
[0051] Preferably, the centrifugal drive component 7 is mounted on the first platform 12, and the vibration generated by the centrifugal drive component 7 during operation does not affect the centrifuge side wall 4 and its heating components, etc.
[0052] In summary, the high-temperature centrifuge base of this invention supports the centrifuge base 3 and the centrifuge side wall 4 respectively by setting independent first supports 1 and second supports 2. The centrifuge base 3 and the centrifuge side wall 4 are flexibly connected, which effectively reduces the transmission of vibrations generated during centrifuge operation to the centrifuge side wall 4. This avoids the impact of centrifugal vibrations on components installed on the centrifuge side wall 4 (such as heating elements, temperature detectors, etc.), reduces maintenance frequency, and extends the service life of the centrifuge. Furthermore, because the vibration of the centrifuge side wall 4 is reduced, the electric heating wire 41 can be directly and stably installed on one side of the centrifuge side wall 4 located in the centrifuge chamber (in traditional high-temperature centrifuges, the heating elements are fixedly installed inside the side wall), resulting in better heating effect, higher thermal energy utilization, and easier maintenance.
