Storage tank for liquefied petroleum gas and method of using the same

Abstract

The present invention discloses a storage tank for liquefied petroleum gas and a method for using the same, comprising a limiting clamping assembly, wherein the upper portion of the limiting clamping assembly stably clamps a storage tank assembly. The present invention transports the storage tank assembly to the upper portion of two arc-shaped support brackets by a machine, supports the storage tank assembly by the two arc-shaped support brackets, and then rotates a driving handwheel. At this time, the driving handwheel drives a reverse-threaded screw to rotate. The rotation of the reverse-threaded screw can move two square movable sliders away from each other. Since the inner end side surface of the strip slide is movably connected to one side surface of the square movable slider via a connecting diagonal rod, when the two square movable sliders move away from each other, the two strip slides are driven closer together, thereby bringing the two limiting clamping rings closer together. The two limiting clamping rings approaching each other can stably clamp the two ends of the storage tank body. The present invention can simply and conveniently achieve stable clamping of the storage tank body.

Description

Technical Field

[0001] The present invention relates to the technical field of liquefied petroleum gas, in particular to a storage tank for liquefied petroleum gas and a method of using the same. Background Art

[0002] Liquefied petroleum gas (LPG) storage tanks are canned containers used to store liquefied petroleum gas (LPG). Because LPG remains stable at room temperature, the operating conditions for LPG storage tanks are much simpler than those for liquefied natural gas (LNG). They are classified into three types: normal temperature pressure tanks, low temperature and normal pressure tanks, and low temperature pressure tanks. The design pressure of these tanks is generally 1.6 MPa or less. Small-capacity tanks generally adopt a horizontal cylindrical structure, while large tanks are more likely to use a spherical structure.

[0003] At present, most of the existing liquefied petroleum gas storage tanks on the market are difficult to stably clamp the storage tank body, and it is difficult to adjust the height of the storage tank body, which leads to a narrow range of use and poor use effect. Based on this, the present invention designs a liquefied petroleum gas storage tank and a method of use thereof to solve the above problems. Summary of the Invention

[0019] As a preferred embodiment, a method for using a liquefied petroleum gas storage tank comprises the following steps:

Then, the driving handwheel is rotated. At this time, the driving handwheel will drive the reverse threaded screw to rotate. The rotation of the reverse threaded screw can make the two square movable sliders move away from each other. Since the inner end side surface of the strip slide is movably connected to one side surface of the square movable slider through the connecting oblique rod, when the two square movable sliders move away from each other, the two strip slides will be driven to move closer to each other, thereby making the two limit clamping rings move closer to each other.

[0021] SS002: Turn on the control switch of the electric telescopic rod, which drives the square end plate to move, thereby changing the tilt angle of the tilt rod, thereby adjusting the height of the limit clamping assembly and the storage tank assembly, making it more convenient to transport;

[0022] SS003: The provision of a movable assembly greatly enhances the flexibility of the present invention, making the liquefied petroleum gas storage tank of the present invention easy to move. When the movable assembly is no longer needed, the movable assembly can be removed from the height adjustment assembly by unscrewing the adjusting nut from the threaded column and then pulling the plug block out of the square plug hole, thereby facilitating replacement or maintenance of the movable assembly.

[0025] Compared with the prior art, the present invention provides a liquefied petroleum gas storage tank and its use method, which has the following beneficial effects:

[0026] 1. The present invention moves the storage tank assembly to the top of the two arc-shaped support brackets through a machine, supports the storage tank assembly through the two arc-shaped support brackets, and then rotates the driving hand wheel. At this time, the driving hand wheel will drive the reverse threaded screw to rotate. The rotation of the reverse threaded screw can make the two square movable sliders move away from each other. Since the inner end side surface of the strip slide is movably connected to one side surface of the square movable slider through the connecting oblique rod, when the two square movable sliders move away from each other, the two strip slides will be driven to move closer to each other, thereby making the two limit clamping rings move closer to each other. The two limit clamping rings move closer to each other to stably clamp the two ends of the storage tank body. The present invention can simply and conveniently achieve stable clamping of the storage tank body.

[0027] 2. The present invention activates the control switch of the electric telescopic rod, which drives the square end plate to move, thereby changing the tilt angle of the tilt rod, thereby adjusting the height of the limit clamping assembly and the storage tank assembly, making it more convenient to transport;

[0028] 3. The present invention can greatly improve the flexibility of the present invention by providing a movable assembly, so that the liquefied petroleum gas storage tank of the present invention is easy to move. When the movable assembly is not needed, the movable assembly can be removed from the height adjustment assembly by unscrewing the adjusting nut from the threaded column and then pulling the plug block out from the inside of the square plug hole, thereby facilitating the replacement or maintenance of the movable assembly.
