Abstract
The invention belongs to the technical field of heat preservation equipment, and particularly relates to a tank bottom heat preservation structure of a low-temperature storage tank. The tank bottom heat preservation structure comprises a tank bottom center structure, the surface of the tank bottom center structure is fixedly connected with a tank bottom ring beam structure, the surface of the tankbottom ring beam structure is fixedly connected with a tank bottom angle bead, a tank body is placed at the top of the tank bottom center structure, the tank bottom center structure comprises a firstconcrete leveling layer, a first foam glass brick is fixedly connected to the top of the first concrete leveling layer, and a novel composite secondary bottom plate is fixedly connected to the top ofthe first foam glass brick. According to the tank bottom heat preservation structure, when the tank bottom center structure and the tank bottom ring beam structure are used, the heat preservation andinsulation effects of a tank bottom are effectively improved, so that the heat preservation effect on the bottom of the tank body is achieved in use, and the situation that the normal use of the tankbody is affected due to the fact that external heat enters the tank body in use is avoided.
Description
technical field [0001] The invention relates to the technical field of thermal insulation equipment, in particular to a tank bottom thermal insulation structure of a cryogenic storage tank and a preparation method thereof. Background technique [0002] When using low-temperature storage tanks, it is necessary to insulate the bottom of the tank, which is called an insulation structure. For example, CN201721872375.2 discloses a fermentation tank bottom insulation structure, which is arranged on the body of the fermentation tank The lower part of the bottom plate includes a fine stone concrete layer, an extruded board insulation layer, a waterproof layer, a concrete cushion and a graded sandstone cushion arranged in sequence from top to bottom. Through multi-level settings, effective and reasonable layout, the overall thermal insulation structure can bear the weight of the entire fermentation tank and the weight of the biogas liquid in it, with good thermal insulation performan...
