Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automatic pressure-replenishing devices for storage tanks, and in particular relates to a pressure-regulating automatic pressure-replenishing device for storage tanks. Background Art
[0002] When volatile component materials are loaded into the storage tank, nitrogen needs to be input into the storage tank at a slight pressure for nitrogen sealing. In the prior art, when the storage tank is discharged, the nitrogen is discharged along with the materials, and the pressure in the storage tank decreases rapidly. However, the original nitrogen input device cannot meet the timely replenishment of nitrogen in the storage tank, which has a great impact on the balance of air pressure in the storage tank. Utility Model Content
[0003] In order to solve the above-mentioned deficiencies of the prior art, the utility model provides a pressure regulating type storage tank automatic pressure replenishing device, and its technical solution includes:
[0004] A storage tank, an exhaust pipe is provided on the storage tank, a breathing valve is provided on the exhaust pipe, and the storage tank is characterized in that a distribution device is provided in the storage tank, a micro-pressure regulating device is provided on the storage tank, the micro-pressure regulating device is connected to the distribution device through a pipeline, a normal pressure regulating device is provided on the storage tank, the normal pressure regulating device and the micro-pressure regulating device are connected through a pipeline, a pipeline connecting a pressure remote transmission instrument is provided on the storage tank, and the pipeline is respectively connected to the micro-pressure regulating device and the normal pressure regulating device.
[0005] Furthermore, the micro-pressure regulating device includes a pipeline connected to the distribution device, and a shut-off valve and a micro-pressure valve are arranged on the pipeline from left to right in sequence, and the pipeline on the remote pressure transmission instrument is connected to the micro-pressure valve.
[0006] Furthermore, the normal pressure regulating device includes a pipeline connected to the storage tank, and a shut-off valve 2 and a normal pressure valve are sequentially arranged on the pipeline from left to right, and the pipeline on the remote pressure transmission instrument is connected to the normal pressure valve.
[0007] Furthermore, the distribution device includes a distributor arranged in the storage tank, and a plurality of air holes are arranged on the distributor.
[0008] Compared with the prior art, the utility model has the following advantages:
[0009] Under normal circumstances, the atmospheric pressure regulating device is closed and the micro-pressure regulating device is opened. Nitrogen enters the distribution device in the form of micro-pressure and is distributed in the storage tank through the distribution device to nitrogen-seal the volatile gas in the storage tank. At the same time, a small amount of volatile gas and nitrogen in the storage tank are slowly discharged through the exhaust pipe and the breathing valve. When the storage tank is discharged, the nitrogen in the storage tank is discharged along with the material, and the air pressure in the storage tank decreases. The pressure remote transmission instrument detects it and transmits the signal to the micro-pressure regulating device and the atmospheric pressure regulating device. The micro-pressure regulating device is closed, and the atmospheric pressure regulating device is opened and nitrogen is introduced to automatically and quickly replenish the pressure in the storage tank.
[0010] The distribution device adopted by the utility model can intercept and condense the mist particles in the volatile gas in the storage tank to form mist droplets. After the atmospheric pressure regulating device is opened, the nitrogen can also purge the condensed mist droplets to make them fall quickly. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Example
[0015] like Figure 1 As shown:
[0016] The present invention provides a pressure regulating type automatic pressure replenishing device for a storage tank, and the implementation scheme thereof is as follows: under normal circumstances, a normal pressure regulating device is closed, a micro-pressure regulating device is opened, nitrogen enters a distribution device in a micro-pressure form, is distributed in a storage tank 1 through the distribution device, and nitrogen is sealed on the volatile gas in the storage tank 1. At the same time, a small part of the volatile gas and nitrogen in the storage tank 1 are slowly discharged through an exhaust pipe 2 and a breathing valve 3. When the storage tank 1 is discharged, the nitrogen in the storage tank 1 is discharged along with the material, and the air pressure in the storage tank 1 becomes smaller. A pressure remote transmitter 4 detects this and transmits a signal to the micro-pressure regulating device and the normal pressure regulating device. The micro-pressure regulating device is closed, and the normal pressure regulating device is opened and nitrogen is introduced, so that the pressure in the storage tank 1 is automatically and quickly replenished.
[0017] In a preferred embodiment, the micro-pressure regulating device includes a pipeline connected to the distribution device and a shut-off valve 5 and a micro-pressure valve 6 are arranged on the pipeline from left to right in sequence. The pipeline on the pressure remote transmission instrument 4 is connected to the micro-pressure valve 6. The shut-off valve 5 controls the opening and closing of the pipeline, and the micro-pressure valve 6 ensures that the nitrogen in the pipeline is transported in the form of micro-pressure.
[0018] In a preferred embodiment, the atmospheric pressure regulating device includes a pipeline connected to the storage tank 1 and a shut-off valve 7 and an atmospheric pressure valve 8 are arranged on the pipeline from left to right in sequence. The pipeline on the pressure remote transmission instrument 4 is connected to the atmospheric pressure valve 8. The shut-off valve 7 controls the opening and closing of the pipeline. The atmospheric pressure valve 8 ensures that the nitrogen in the pipeline is transported at atmospheric pressure.
[0019] In the preferred embodiment, the distribution device includes a distributor 9 disposed in the storage tank 1, and a plurality of air holes 10 are provided on the distributor 9. The distributor of the storage tank 1 is used to control the escape of volatile gases of the material and to isolate the nitrogen distribution, and also to intercept and condense the mist particles in the volatile gas in the storage tank 1 to form droplets.

At the same time, a small part of the volatile gas and nitrogen in the storage tank 1 are slowly discharged through the exhaust pipe 2 and the breathing valve 3. When the storage tank 1 is discharged, the nitrogen in the storage tank 1 is discharged along with the material, and the air pressure in the storage tank 1 becomes smaller. The pressure remote transmitter 4 detects it and transmits the signal to the micro-pressure valve 6 and the normal pressure valve 8. The micro-pressure valve 6 and the shut-off valve 1 5 are closed, the shut-off valve 2 7 and the normal pressure valve 8 are opened, and the nitrogen enters the storage tank 1 through the shut-off valve 2 7 and the normal pressure valve 8, and the pressure in the storage tank 1 is automatically and quickly replenished.
