Description
Technical field
A kind of nitrate negative pressure lifting system is the utility model is related to, belongs to propellant manufacturing field.
Background technology
During the manufacture research and production of propellant containing nitrate, nitrate preparation demand is big, and technics comparing is answered
Miscellaneous, process also danger close, traditional nitrate lifting process, is to depend merely on manpower, and nitrate solution movement is promoted into high-order storage tank
Mode, the technique can not meet the needs of existing production technology, and efficiency is also than relatively low, and operating personnel directly connect
It is dangerous high to touch nitrate, is especially not suitable with continuous production, so having to meet to criticize by safely controllable lifting process
Measure production requirement.
Utility model content
The purpose of this utility model is that operational danger is high in existing nitrate lifting process, operating efficiency is low in order to solve
The problems such as, and a kind of nitrate negative pressure lifting process is provided.
The purpose of this utility model is achieved through the following technical solutions：
A kind of nitrate negative pressure lifting system of the present utility model, including it is low level storage tank, liquid level gauge, transfer pipeline, pneumatic
Pipe clamp, flowmeter, high-order storage tank, vavuum pump, aeration valve；
Low level storage tank is the Liquid storage container of upper end open, and pressure-type liquidometer is provided with low level storage tank,
High-order storage tank is the Liquid storage container of closing, and the upper end of high-order storage tank connects vavuum pump and tonifying Qi by pipeline respectively
Valve, floating ball type liquid-level meter and vacuum meter are provided with high-order storage tank；
The upper end of high-order storage tank stretches out transfer pipeline and extends to low level sump bottom, sets flowmeter gentle on transfer pipeline
Dynamic pipe clamp.
Its course of work is：
Vavuum pump and aeration valve are first turned on, the vacuum in high-order storage tank is adjusted and reaches 400-500mmHg scopes, is led to
Cross aeration valve and maintain whole pipeline negative pressure dynamic equilibrium；Then the nitric acid ester solution that pneumatic tubing clip stores by low level storage tank is opened to lead to
Cross negative pressure and flow slowly into high-order storage tank through transfer pipeline；
Set liquid level warning line respectively to low level storage tank and high-order storage tank, the liquid level in low level storage tank must not be less than low level and store
The 1/5 of groove inner chamber total height, the liquid level in high-order storage tank must not be higher than the 1/5 of high-order storage tank inner chamber total height；
When any liquid level gauge of low level storage tank or high-order storage tank, which is shown, reaches respective liquid level warning line, pneumatic tube is closed
Folder and vavuum pump.
Beneficial effect
Negative pressure lifting system of the present utility model, it is simple to operate, it is safely controllable the advantages of, reduce labor strength,
Improve production efficiency, have can continuous production the characteristics of.

Embodiment
Content of the present utility model is further described with reference to the accompanying drawings and examples.
Embodiment
A kind of nitrate negative pressure lifting system of the present utility model, as shown in figure 1, including low level storage tank 8, liquid level gauge, defeated
Send pipeline 5, pneumatic tubing clip 7, flowmeter 6, high-order storage tank 1, vavuum pump 3, aeration valve 2；
Low level storage tank 8 is the Liquid storage container of upper end open, and pressure-type liquidometer 10 is provided with low level storage tank 8,
High-order storage tank 1 is the Liquid storage container of closing, and the upper end of high-order storage tank 1 connects vavuum pump 3 by pipeline respectively and mended
Air valve 2, floating ball type liquid-level meter 4 and vacuum meter 9 are provided with high-order storage tank 1；
The upper end of high-order storage tank 1 stretches out transfer pipeline 5 and extends to the bottom of low level storage tank 8, and flowmeter is set on transfer pipeline 5
6 and pneumatic tubing clip 7.
Its course of work is：
Vavuum pump 3 and aeration valve 2 are first turned on, the vacuum in high-order storage tank is adjusted and reaches 400-500mmHg scopes,
Whole pipeline negative pressure dynamic equilibrium is maintained by aeration valve 2；Then it is molten to open the nitrate that pneumatic tubing clip 7 allows low level storage tank to store
Liquid flows slowly into high-order storage tank by negative pressure through transfer pipeline 5；
Set liquid level warning line respectively to low level storage tank 8 and high-order storage tank 1, the liquid level in low level storage tank 8 must not be less than low
The 1/5 of position storage tank inner chamber total height, the liquid level in high-order storage tank 1 must not be higher than the 1/5 of high-order storage tank inner chamber total height；
When any liquid level gauge of low level storage tank 8 or high-order storage tank 1, which is shown, reaches respective liquid level warning line, close pneumatic
Pipe clamp and vavuum pump.
