The beneficial effects of this technical scheme lie in: the evacuation pipe is in an inverted U shape, rainwater and sundries cannot fall into the anti-freezing liquid tank while nitrogen is discharged, and an electric heating wire or an electric heater is arranged on the outer side of the evacuation pipe to ensure that liquid nitrogen is vaporized into nitrogen to be discharged, so that potential safety hazards cannot be generated.
Description
Technical Field
The utility model relates to a chemical industry equipment field, in particular to can be used for liquid nitrogen evacuation's frostproofing fluid reservoir.
Background
The antifreeze solution is commonly used in the chemical industry, because the antifreeze solution has a short shelf life at normal temperature and needs to be stored at a low temperature, if the liquid nitrogen is used for maintaining the low temperature, gas generated by vaporization of the liquid nitrogen cannot be discharged from the antifreeze solution tank, so that potential safety hazards are caused, the antifreeze solution tank which can be used for emptying the liquid nitrogen is needed, and in addition, rainwater or other impurities cannot fall into the antifreeze solution tank.
Disclosure of Invention
In order to solve the problems, the utility model provides a can be used for the liquid nitrogen evacuation and can not let rainwater or debris fall into prevent frostbite fluid reservoir.
The technical scheme of the utility model is that: the utility model provides a can be used for antifreeze fluid reservoir of liquid nitrogen evacuation, includes at least that antifreeze fluid reservoir jar body, antifreeze fluid reservoir tank top is equipped with the evacuation pipe that is located jar external portion, and the evacuation pipe is "U" font and the exit end of evacuation pipe is down.
And an electric heating wire or an electric heater is arranged on the outer side of the emptying pipe, and a screen is arranged at the outlet end of the emptying pipe.
And the outlet end of the emptying pipe is provided with a silencer.
And an antifreeze liquid storage part is arranged in the middle of the antifreeze liquid tank body, a liquid nitrogen manifold is arranged outside the antifreeze liquid storage part, and the emptying pipe is connected with the liquid nitrogen manifold in the antifreeze liquid tank body.
When the anti-freezing liquid tank is used, nitrogen generated by vaporization of liquid nitrogen is discharged through the inverted U-shaped emptying pipe at the top of the anti-freezing liquid tank. The nitrogen gas discharged from the emptying pipe is accompanied with a small amount of liquid nitrogen sometimes, and the liquid nitrogen can cause frostbite if dropping to a worker from the pipe orifice, so that an electric heating wire or an electric heater is arranged outside the emptying pipe to heat the emptying pipe so as to ensure that the liquid nitrogen is vaporized into the nitrogen gas to be discharged.
The beneficial effects of this technical scheme lie in: 1. because the emptying pipe is in an inverted U shape, rainwater and sundries cannot fall into the tank from the outlet end of the emptying pipe, and the nitrogen emptying is not influenced; 2. an electric heating wire or an electric heater is arranged on the outer side of the emptying pipe to ensure that the liquid nitrogen is vaporized into nitrogen gas to be discharged, and potential safety hazards cannot be generated; 3. the outlet end of the emptying pipe is provided with a screen mesh to ensure that no other sundries such as winged insects and the like fly into the emptying pipe; 3. the outlet end of the emptying pipe can be provided with a silencer, so that the noise is reduced, and the sound pollution to the environment is reduced.
Drawings
FIG. 1 is a schematic view of the present invention;
description of reference numerals: 1. an anti-freezing liquid tank; 2. emptying the pipe; 3. an electric heating wire; 4. a muffler; 5. and (4) screening.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, and as shown in fig. 1, an antifreeze liquid tank capable of being used for liquid nitrogen evacuation is provided, wherein an evacuation pipe 2 located outside a tank body is arranged at the top of the antifreeze liquid tank 1, the evacuation pipe is in an inverted U shape, an outlet end of the evacuation pipe faces downwards, an electric heating wire 3 or an electric heater is arranged outside the evacuation pipe, an outlet end of the evacuation pipe is provided with a screen 5, and an outlet end of the evacuation pipe is provided with a silencer 4.
If a liquid nitrogen manifold is arranged in the anti-freezing liquid tank body for containing liquid nitrogen, the emptying pipe is connected with the liquid nitrogen manifold in the anti-freezing liquid tank body. If the liquid nitrogen is directly placed in the anti-freezing liquid tank, the emptying pipe is communicated with the space where the liquid nitrogen is located.
When the anti-freezing liquid is used, the liquid nitrogen provides the anti-freezing liquid with low temperature, the liquid nitrogen is heated and vaporized into nitrogen, the nitrogen is discharged through the inverted U-shaped emptying pipe at the top of the anti-freezing liquid tank, rainwater and impurities cannot fall into the tank from the pipe orifice because the outlet end of the emptying pipe faces downwards, and the screen can ensure that no winged insects and the like enter the emptying pipe; an electric heating wire or an electric heater is arranged on the outer side of the emptying pipe to heat the emptying pipe so as to ensure that liquid nitrogen is vaporized into nitrogen gas to be discharged, thereby avoiding potential safety hazards caused by that a small amount of liquid nitrogen carried by the emptied nitrogen gas falls out of the tank, simultaneously ensuring that the liquid nitrogen is vaporized into the nitrogen gas, avoiding white fog generated by vaporization of the liquid nitrogen outside the tank, and keeping a good visual field of a working environment; the silencer further reduces the sound pollution to the environment.
The beneficial effects of this technical scheme lie in: 1. because the emptying pipe is in an inverted U shape, rainwater and sundries cannot fall into the tank from the outlet end of the emptying pipe, and the nitrogen emptying is not influenced; 2. an electric heating wire or an electric heater is arranged on the outer side of the emptying pipe to ensure that the liquid nitrogen is vaporized into nitrogen gas to be discharged, and potential safety hazards cannot be generated; 3. the outlet end of the emptying pipe is provided with a screen mesh to ensure that no other sundries such as winged insects and the like fly into the emptying pipe; 3. the outlet end of the emptying pipe can be provided with a silencer, so that the noise is reduced, and the sound pollution to the environment is reduced.
The above is only the preferred embodiment of the present invention, and is not used to limit the present invention, the technical concept of the present invention can be modified to various simple modifications, and these simple modifications all belong to the protection scope of the present invention.
