Storage tank

Abstract

The invention discloses a storage tank. The storage tank comprises a tank body, an inner container, an operating system and a supporting device. Pipes of the operating system penetrate through the tank body and then communicate with the inner container. The supporting device comprises a fixed supporting device and two sliding supporting devices. One end of the fixed supporting device and one ends of the two sliding supporting devices make contact with the inner container. The other ends of the fixed supporting device and the two sliding supporting devices are fixed to the tank body. The operating system is arranged below the middle portion of the tank body. The fixed supporting device is arranged in the middle of the tank body. The sliding supporting devices are arranged at the two ends of the tank body. All the pipes extend out of the tank body from the lower portion of the middle of the tank body. The tank body is formed by connecting two cylinders towards the center in a sleeved mode. Through the spatial layout of the lower portion of the tank body of the storage tank and installation of the pipes, valves, instruments and meters, the length of the tank body does not need to be shortened. When the operating system is adopted for the storage tank, the fixed supporting device is arranged in the middle of the tank body, the vertical deflection of the middle of the tank body can be reduced, and the bearing capacity of the high-load storage tank is higher.

Description

technical field [0001] The invention relates to the technical field of refrigerated liquefied gas, in particular to a storage tank. Background technique [0002] The FRP support device is an important device used to connect the inner and outer container tanks, transfer the load of the inner container and reduce heat leakage. The refrigerated liquefied gas tank generally adopts a double-layer tank structure, the inner container is used to load the refrigerated liquefied gas, and the outer shell is connected with the frame, chassis, saddle or running gear. In order to effectively block the heat from the external environment into the inner container and avoid the refrigerated liquefied gas from evaporating too quickly, an epoxy fiberglass support device is usually installed between the inner container and the outer shell to support the inner container on the outer shell to form a sandwich space, and then the interlayer Vacuum the space. [0003] The glass fiber reinforced pla...

Problems solved by technology

[0006] This application provides a storage tank, which solves the problem of increased deflection in the prior art due to the large distance between the fixed end and the sliding end of the glass fiber reinforced plastic support device, the tank body is prone to instability, and the tank body has a large volume and a lot of media loaded.
