Embodiment approach
[0047] In a further embodiment of the present invention, the tank body 1 is filled with liquid, and the volume of the liquid reaches 2 / 3 of the volume of the tank body 1 to ensure that there is a liquid level in the tank during operation.
[0048] In a further embodiment of the present invention, the material is pumped out from the bottom of the tank body 1 by the water transfer pump 3 .
[0049] In a further embodiment of the present invention, the outlet of the tank body 1 is lower than the liquid level in the tank, and the exhaust valve 2 is in a normally open state.
[0050] In a further embodiment of the present invention, the exhaust valve 2 is normally closed when it starts up normally and stably, and when the exhaust valve 2 is abnormal, the valve fails, and the tank body 1 is at normal pressure.
[0051] In a further embodiment of the present invention, the inside of the tank 1 is under normal pressure, the liquid level in the tank reaches 2 / 3, the length of the first...

The invention discloses a siphon breaking device. The siphon breaking device comprises a tank body, an exhaust valve, a water delivery pump, an underground pool and a check valve, and further comprises a first pipeline, a second pipeline and a third pipeline, wherein the tank body is filled with liquid, so that the liquid level in the tank body is guaranteed during the operation period, materialsare pumped out from the bottom of the tank body through the water delivery pump, a discharge port of the tank body is lower than the liquid level in the tank body, and the exhaust valve is in a normally open state; the exhaust valve is normally closed when being normally and stably started, and the valve fails when the exhaust valve is abnormal; the tank body is at normal pressure, the check valveis reversely installed, if a siphon phenomenon occurs, external air enters the pipelines, so that the pipeline is cut off, when the system operates normally, the materials in the second pipeline cannot be conveyed outwards, and the siphon phenomenon cannot occur; and the third pipeline is inserted below the liquid level. According to the siphon breaking device, the check valve is additionally arranged at the high point of the pipeline, the siphon breaking device is reversely installed, manual operation is not needed, the system can stably operate, and the siphon breaking device is suitable for a non-closed container.
Description
technical field [0001] The invention relates to the technical field of siphon breaking devices, in particular to a siphon breaking device. Background technique [0002] The stability of the system is the main factor to determine the performance of the system during the commissioning and operation of the chemical plant. Siphon is a common phenomenon in many chemical production and process, equipment maintenance process. The siphon phenomenon is likely to cause the liquid in the pipeline to be unclean and affect the maintenance progress. If the siphon phenomenon occurs in the pipeline of chemical hazardous chemicals, it will cause a major safety accident. For this reason, it is necessary to add a set of broken siphon device, thereby reducing the impact of siphon phenomenon on production stability. Contents of the invention [0003] In view of the above-mentioned problems, the object of the present invention is to provide a siphon breaking device. [0004] In order to ach...
