Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of storage tanks, in particular to a storage tank suction valve air supplementing system with filtering and drying functions and a storage tank thereof. BACKGROUND

[0002] A storage tank is a sealed container for storing various liquids, gases, and solid materials. Some raw materials need to be temporarily stored in a buffer tank when being filled into a storage tank to alleviate the pulse pressure, so that the flow rate and pressure of the material entering the storage tank tend to be stable, and the storage tank and pipeline interface are protected. The size of the buffer tank is affected by the type of raw material, the ambient temperature, the size of the storage tank, etc. During transportation, the external environment temperature changes drastically (such as alternating between summer sun exposure and night low temperature, sudden cooling and heating when crossing climate zones), or the raw material itself has characteristics (such as evaporation of volatile liquids, moisture absorption and heat release of hygroscopic solids, and trace gas production of chemically reactive materials), the pressure in the tank is prone to abnormal fluctuations. In a high-temperature environment, the evaporation of raw materials or the expansion of air in the tank due to heat may cause overpressure. If the pressure exceeds the pressure limit of the storage tank, it may cause the sealing element to fail, the interface to leak, or even the tank body to crack. In a low-temperature environment, the condensation and contraction of raw materials or the contraction of air in the tank due to cooling may form negative pressure, causing the storage tank to deform, which not only damages the structural integrity, but also may cause air to suck in impurities and contaminate the raw materials.

The pressure reducing system includes a first pressure reducing valve and a second pressure reducing valve, which are connected in parallel through a switching valve and connected with the air supplementing main pipe. A third pressure reducing valve is connected to the air supplementing main pipe at the other end of the first pressure reducing valve and the second pressure reducing valve. An air supplementing valve is connected to the air supplementing main pipe on one side of the third pressure reducing valve.

[0004] A low-temperature double-layer storage tank is disclosed in Chinese Patent No. CN120027348A, which includes an outer tank body, an inner tank body, an inner support assembly, and an outer support assembly. The inner tank body is spaced apart and accommodated in the outer tank body, and is used to accommodate a low-temperature liquid medium. The inner support assembly includes a plurality of inner supports spaced apart along the axial direction of the inner tank body. The top of the inner support is fitted to the outer periphery of the inner tank body, and the bottom of the inner support extends downward to pass through the outer tank body.

[0050] As shown in Figure 1 , Figure 7 , Figure 8 , Figure 9 The pressure balancing mechanism comprises: a breathing valve 31, the fixed end of the breathing valve 31 is fixedly installed on the tank body 1, and the pressure inside and outside the tank body 1 is controlled by the breathing valve 31 to be maintained within a certain range.

[0051] The gas drying mechanism comprises: a third valve 32 and a drying pipe 33, one end of the third valve 32 is fixedly connected to the exhale end of the breathing valve 31, the drying pipe 33 is fixedly installed on the tank body 1, the end of the third valve 32 away from the breathing valve 31 is fixedly connected to the drying pipe 33, and the drying pipe 33 is filled with reusable regenerated drying agent such as silica gel drying agent.

[0052] The gas drying mechanism further comprises: a back-blowing drying assembly, which is installed on the upper side of the drying pipe 33, the back-blowing drying assembly comprises: a fourth valve 34, a connecting pipe 35, a heating wire 36, a fan 37 and a first filter screen 38, one end of the fourth valve 34 is fixedly installed on the upper side of the drying pipe 33, the connecting pipe 35 is fixedly installed on the end of the fourth valve 34 away from the drying pipe 33, the heating wire 36 is fixedly installed in the connecting pipe 35, the fan 37 is fixedly installed in the connecting pipe 35, and the first filter screen 38 is fixedly installed on the upper side of the connecting pipe 35.

For example, part of some liquefied gas will rapidly become gas after losing pressure. The tank 1 has a small self-weight and a small size. When the impact force is large, the tank 1 will move under the impact. At this time, the tank 1 moves to drive the support arc-shaped plate 41 to rotate on the sliding support 42 to drive the elastic buffer 43 to elastically deform. The impact force is absorbed by the elastic buffer 43 to avoid the tank 1 from falling down to cause a loss after being impacted. At the same time, the volume of the whole device changes little when the tank 1 rotates. The tank 1 can also avoid bumping into the surrounding equipment. This is favorable to reduce the impact force generated by the device when the device is loaded or transported.
