Description

Technical Field

[0001] The utility model relates to the technical field of buffer tanks, in particular to a light hydrocarbon gas buffer tank. Background Art

[0002] Light hydrocarbon gas buffer tanks are used for storage and buffering of compressed light hydrocarbon gas at light hydrocarbon gas stations, and are placed vertically or horizontally. At present, in the light hydrocarbon gas transmission system, in order to meet the different needs of different transmission equipment and gas-using equipment for gas usage, use pressure, and use temperature, when transferring between different gas transmission and application systems, it is often necessary to use buffer tanks to temporarily store and regulate the temperature and pressure of the gas.

[0003] For example, a patent entitled A Light Hydrocarbon Gas Buffer Tank (patent application number: CN210319398U) discloses a light hydrocarbon gas buffer tank, which realizes gas buffering by driving the rotation of a fan through the gas flow. However, since the fan blades are arranged on a rotating circle and a sliding rod is fixed on the outer wall of the rotating circle, during actual use, the gas flow formed by the gas will pass through the space outside the rotating circle at the same time. Therefore, the gas pressure entering the buffer tank cannot be well relieved, and the buffering effect is poor. At the same time, impurities will be enriched on the scraper, resulting in increased resistance, which makes the fan unable to rotate.

[0004] Therefore, it is necessary to propose a light hydrocarbon gas buffer tank to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a light hydrocarbon gas buffer tank to solve the problem that, since the fan blades are arranged on a rotating circle and a sliding rod is fixed on the outer wall of the rotating circle, during actual use, the airflow formed by the gas will simultaneously pass through the space outside the rotating circle. Therefore, the gas pressure entering the buffer tank cannot be well relieved, and the buffering effect is poor. At the same time, impurities will be enriched on the scraper, resulting in increased resistance, making the fan unable to rotate.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a light hydrocarbon gas buffer tank, comprising a buffer tank body, a gas supply port and an exhaust port are respectively arranged on both sides of the top of the buffer tank body, the gas supply port and the exhaust port are both connected to the interior of the buffer tank body, a spring telescopic rod is arranged at the bottom of the buffer tank body, the upper half of the spring telescopic rod extends into the interior of the buffer tank body, and the top of the spring telescopic rod is connected with a telescopic end, a buffer plate is fixed on the top of the telescopic end, an annular cleaning block is sleeved on the outer side of the buffer plate, and the outer side of the annular cleaning block is fitted to the inner wall of the buffer tank body.

[0007] Preferably, a bottom plate is fixed to the bottom of the telescopic end, and a pressure sensor is provided at the connection between the bottom plate and the telescopic end.

[0008] Preferably, an electric push rod is provided on one side of the bottom end of the buffer tank body, an electromagnet is fixed to the top end of the electric push rod, an adsorption block is fixed to the bottom end of the buffer plate, and the adsorption block and the corresponding electromagnet are adsorbed and connected.

[0009] Preferably, a discharge pipe is provided at the bottom end of the buffer tank body, and the discharge pipe is communicated with the interior of the buffer tank body. A plurality of supporting legs are fixedly connected to the bottom end of the buffer tank body, and the bottom ends of the plurality of supporting legs are flush.

[0010] Preferably, the bottom end of the electric push rod extends out of the bottom of the buffer tank, and the bottom end of the electric push rod is flush with the bottom end of the supporting leg.

[0011] Technical effects and advantages of the utility model:

[0012] 1. In the actual operation of the present invention, when the gas enters the interior of the buffer tank, the buffer plate hinders the gas flow, and the gas flow will squeeze the buffer plate downward, causing the telescopic end of the spring telescopic rod to retract downward, converting the pressure of the gas flow into the squeezing force of the spring telescopic rod, which has a buffering effect on the airflow. At the same time, the pressure on the buffer plate will be transmitted to the pressure sensor. As the gas continues to enter, the value of the pressure sensor will continue to change, thereby allowing outsiders to know the storage situation of the gas inside the buffer tank.

[0013] 2. In the actual operation of the present invention, the electric push rod and the electromagnet can be started so that the electromagnet is energized to generate magnetic force, and adsorbs and corresponds to the corresponding adsorption block, so that a connection is established between the buffer plate and the electric push rod. The electric push rod extends upward, actively driving the buffer plate to rise, so that the space between the buffer plate and the top of the buffer tank body becomes smaller, squeezing the storage space of the gas, increasing the air pressure, and thus adjusting the gas pressure.

[0014] 3. Furthermore, when the buffer plate moves up and down, the annular cleaning block will wipe and clean the inner wall of the buffer tank to reduce the residual liquid and impurities and avoid accumulation problems. BRIEF DESCRIPTION OF THE DRAWINGS
