Description

Technical Field

[0001] The invention relates to the technical field of chemical pressure vessels, and in particular to a negative pressure adsorption chemical tank body sealing and plugging device for emergency rescue. Background Art

[0002] During use, chemical pressure vessels and other tanks are easily damaged and failed due to corrosion, cracking, etc. due to the influence of the use environment, which causes the medium inside the tank to leak from the failure point, thereby causing fire, explosion or significant impact on the environment. This situation is common in the chemical industry. However, at present, when a local leak occurs in the tank, due to the lack of a fixed positioning position, it is not possible to use a clamp to add an agent to seal the leak like a pressure pipe leak. In the prior art, when a tank leaks, it is usually necessary to pour the medium inside the leaked tank into other intact tanks by inverting the tank at the risk of leakage. This method is highly dangerous.

[0003] Therefore, it is urgent to design a sealing and leak-proof device for use when the tank leaks. Summary of the invention

[0004] The main purpose of the present invention is to provide a negative pressure adsorption chemical tank sealing and plugging device for emergency rescue, so as to overcome the problems existing in the prior art.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A negative pressure adsorption chemical tank sealing and plugging device for emergency rescue, comprising a negative pressure adsorption base, a bearing top cover, a first connecting pipe and a second connecting pipe, one side of the negative pressure adsorption base is adsorbed on the leakage position of the chemical tank, the bearing top cover is arranged on the other side of the negative pressure adsorption base, the first connecting pipe is connected to the inner cavity of the negative pressure adsorption base, and the second connecting pipe is connected to the bearing top cover.

[0007] Furthermore, the first connecting pipe is provided with a valve 1, and the second connecting pipe is provided with a valve 2.

[0008] Furthermore, the negative pressure adsorption base and the bearing top cover are an integrally formed structure.

[0009] Furthermore, one end of the first connecting tube is connected to the inner cavity of the negative pressure adsorption base, and the other end is connected to a vacuum pump.

[0010] Furthermore, the inner cavity of the negative pressure adsorption base is an annular groove structure.

[0011] Furthermore, the connection point between the bearing top cover and the negative pressure adsorption base is located on the arc surface of 90°-180° of the negative pressure adsorption base. When the internal gas leaks into the bearing top cover, the medium in the bearing top cover generates external pressure on the negative pressure adsorption base, thereby increasing the adsorption force between the negative pressure adsorption base and the chemical tank.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The sealing leak-stopping device of the present invention is arranged around the leakage position of the chemical tank, which can prevent the medium inside from leaking continuously, and the medium is no longer transferred by inverting the tank, thereby improving safety.

[0023] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0024] Combination Figures 1 to 8The present embodiment provides a negative pressure adsorption chemical tank sealing and plugging device for emergency rescue, comprising a negative pressure adsorption base 1, a bearing top cover 2, a first connecting pipe 3 and a second connecting pipe 4. One side of the negative pressure adsorption base 1 is adsorbed on the leakage position of the chemical tank 5, and the bearing top cover 2 is arranged on the other side of the negative pressure adsorption base 1. The first connecting pipe 3 is connected to the inner cavity of the negative pressure adsorption base 1, and the second connecting pipe 4 is connected to the bearing top cover 2.

[0025] When in use, the sealing and leak-stopping device is covered around the leaking position of the chemical tank 5 .

[0026] In this embodiment, a first valve is provided on the first connecting pipe 3 , and a second valve is provided on the second connecting pipe 4 .

[0027] Preferably, the negative pressure adsorption base 1 and the bearing top cover 2 are an integrally formed structure.

[0028] In this embodiment, one end of the first connecting tube 3 is connected to the inner cavity of the negative pressure adsorption base 1, and the other end is connected to a vacuum pump. The vacuum pump is used to evacuate the inner cavity of the negative pressure adsorption base 1 to a negative pressure state so that it can be adsorbed on the chemical tank 5.

[0029] In this embodiment, the inner cavity of the negative pressure adsorption base is an annular groove structure 6 .

[0030] Reference Figure 6-Figure 7 The connection point between the bearing top cover 2 and the negative pressure adsorption base 1 is located on the arc surface of the negative pressure adsorption base at 90°-180°. When the internal gas leaks into the bearing top cover 2, the medium in the bearing top cover 2 generates external pressure on the negative pressure adsorption base 1, thereby increasing the adsorption force between the negative pressure adsorption base 1 and the chemical tank 5.

[0031] How it works:

[0032] When a chemical tank leaks, the staff enters the leakage area with the sealing and plugging device of this embodiment, places the negative pressure adsorption base 1 around the leakage position of the tank, opens valve 1 on the first connecting pipe 3 connected to the negative pressure adsorption base 1 and valve 2 on the second connecting pipe 4 connected to the bearing top cover 2, and then starts the vacuum pump to evacuate the inner cavity of the negative pressure adsorption base 1. At this time, the negative pressure adsorption base 1 adheres to the leaking tank under vacuum negative pressure, and then closes valve 1 and valve 2. The medium leaking from the tank is blocked by the negative pressure adsorption base 1 and the bearing top cover 2 to avoid continuous leakage of the medium.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
