Abstract

The present invention discloses a multi-screen supporting device in a high-temperature adiabatic calorimeter, and belongs to a calorimeter device in calorimetry. The multi-screen supporting device comprises a vacuum tank, three layers of protecting screens, two layers of thermal insulation screens, a protecting screen supporter for supporting and fixing the protecting screens, a thermal insulation screen supporter for supporting and fixing the thermal insulation screens, and a connecting piece for connecting and fixing the protecting screen supporter and the thermal insulation screen supporter. The multi-screen supporting mode in the high-temperature calorimeter solves the problems of time consumption for disassembling and assembling, low multi-screen assembling coaxiality and reduced experimental repeatability caused by many parts moved in each disassembling and assembling in the existing high-temperature calorimeter. The multi-screen supporting mode is easy in part processing, high in disassembling and assembling efficiency and convenient in operation, and effectively improves the experimental repeatability.

First claim

1. A multi-screen supporting device, comprising:
a vacuum tank;
thermal insulation screens disposed within the vacuum tank;
a thermal insulation screen supporter supporting the thermal insulation screens within the vacuum tank, the thermal insulation screen comprising:
a stepped supporting rod;
a first nut at a top of the stepped supporting rod
a second nut at a bottom of the stepped supporting rod; and
a sleeve sleeved outside the stepped supporting rod between the first nut and the second nut; and

a connecting piece;
protecting screens disposed within the vacuum tank adjacent to the thermal insulation screens;
a protecting screen supporter supporting the protecting screens within the vacuum tank, the protecting screen supporter comprising:
a third nut;
a supporting tube, the supporting tube comprising:
a bottom threaded end having a sealed thread connected with the vacuum tank; and
an upper threaded end in threaded connection with the connecting piece and the third nut; and

stainless steel sleeves;
wherein a first stainless steel sleeve of the stainless steel sleeves is sleeved outside the supporting tube,
wherein a second stainless steel sleeve of the stainless steel sleeves is sleeved outside the supporting tube,
wherein a third stainless steel sleeve of the stainless steel sleeves is sleeved outside the supporting tube and positioned at a bottom of the supporting tube, the first stainless steel sleeve being positioned at an upper part of the second stainless steel sleeve and the second stainless steel sleeve being positioned at an upper end of the third stainless steel sleeve;

a lower cover of an outermost one of the protecting screens and a sleeve body penetrating into the third stainless steel sleeve, the outermost one of the protecting screens being supported by the third stainless steel sleeve to limit motion and rotation of the outermost one of the protecting screens along X axis and Y axis and motion along Z axis;
a lower cover of a middle protecting screen and the sleeve body penetrating into the second stainless steel sleeve, the second stainless steel sleeve supporting a middle protecting screen of the protecting screens to limit motion and rotation of the middle protecting screen along X axis and Y axis and motion along Z axis; and
a lower cover of an innermost one of the protecting screens and the sleeve body penetrating into the first stainless steel sleeve, the first stainless steel sleeve supporting the innermost one of the protecting screens to limit motion and rotation of the innermost one of the protecting screens along the X axis and the Y axis and motion along the Z axis;
