A top fixing structure for a vertical flat-bottomed tank

Abstract

The invention discloses a top fixing structure of a vertical flat bottom tank. The top fixing structure comprise a bottom connector, a connecting neck pipe and an installing sleeve, wherein a first installing hole is formed in the top of an inner top seal head; the center of the first installing hole is overlapped with the vertical center of the inner top seal head; the installing sleeve is embedded into the first installing hole and is fixedly welded with the inner top seal head; a vertical step hole is formed in the installing sleeve; the lower end of the connecting neck pipe is inserted into the large diameter hole of the step hole and is fixed with the installing sleeve; a second installing hole is formed in the top center of an outer top seal head; the bottom connector is embedded into the second installing hole and is fixed with the outer top seal head; a vertical through hole is formed in the bottom connector; the connecting neck pipe is fixed with the lower end surface of the bottom connector; the inner hole of the connecting neck pipe, the through hole of the bottom connector and the step hole of the installing sleeve jointly form a wiring channel. According to the top fixing structure, not only is the connecting strength between an inner tank body and an outer tank body guaranteed, but also the heat leakage points of a storage tank are reduced; the guide pipe concentration of a gas phase pipe and a liquid phase pipe is facilitated.

Description

technical field [0001] The invention relates to a top fixing structure, in particular to a 10m 3 The following is the top fixing structure of the vertical flat bottom tank. Background technique [0002] 10m 3 The following vertical flat-bottomed tanks are also called Subida or Quick and Easy Cooling vertical flat-bottomed tanks. Since the vertical flat-bottomed tanks can be transported upright and lying down, the car will generate a buffer force during transportation, which is easy to cause damage to the device. damage, and because the product stores low-temperature liquid, it has high requirements for heat leakage. And present this vertical flat-bottomed tank comprises inner tank body and outer tank body, is provided with heat insulating interlayer between inner tank body and outer tank body, and then adopts in the bottom of outer tank body for fixing between inner tank body and outer tank body There are several support rods welded between the bottom of the outer tank bo...

Problems solved by technology

And present this vertical flat-bottomed tank comprises inner tank body and outer tank body, is provided with heat-insulation interlayer between inner tank body and outer tank body, and then adopts at the bottom of outer tank body for fixing between inner tank body and outer tank body There are several support rods welded between the bottom of the outer tank body and the outer tank body, and several radial supports are arranged between the middle part of the outer tank body and the middle part of the outer tank body; this structure has the following defects; 1. The vertical flat bottom tank leaks There are many hot spots, and the heat leakage of the storage tank can easily lead to frequent opening of the safety valve, causing danger and gas waste; Lead out, the guide tube is messy
