Abstract
The utility model discloses an intelligent nitrogen-sealed water tank which comprises a water tank body, a nitrogen bag, a pressure sensor, a pressure air source, an air inlet solenoid valve and an air exhausting solenoid valve. The input end of the air inlet solenoid valve is connected with the pressure air source, and the output end of the air inlet solenoid valve is connected with a connecting pipeline used for enabling the water tank body and the nitrogen bag to be connected; the input end of the air exhausting solenoid valve is connected with the water tank body, and the output end of the air exhausting solenoid valve is communicated with external atmosphere; the pressure sensor is installed on the water tank body and used for detecting pressure in the water tank body. According to the intelligent nitrogen-sealed water tank, nitrogen sealing through the water tank is achieved, loss of nitrogen cannot occur due to the fact that the nitrogen is exhausted to air, a small amount of the nitrogen is only needed to be supplemented into the bag at regular intervals, consumption of the nitrogen can be greatly reduced, and operating cost is saved.
Description
Technical field
The utility model relates to the coated glass production field, is mainly used in store cleaning the pure water of film-coated glass substrate, and particularly a kind of have a nitrogen seal device pure water holding vessel.
Background technology
A lot of coated glass production and processing industries need to be used pure water in recent years, simultaneously also high to guarantee product quality to the requirement of pure water water quality, and the pure water of general water treatment equipment production must at once be used and should not store, absorbing impurity (dust granules, carbon dioxide etc.) otherwise pure water contacts with air from air can cause ultra-pure water electrical resistivity sharply to descend, directly affect the quality of pure water, and then affect coated product quality (forming piebald, point-like demoulding).In the process of producing pure water, enter water tank for fear of introduced contaminants, gas, reduce pure water water quality, the nitrogen envelope need to be set in the pure water tank.And nitrogen water shutoff tank of the prior art consists of reducing valve and exhaust water seal.When in water pot, liquid level reduces, the nitrogen pressure in water pot reduces, and nitrogen is injected in water pot by reducing valve, maintains the nitrogen pressure of setting; When in water pot, liquid level rises, the pressure rise of nitrogen, nitrogen is discharged in air by the exhaust water seal.The critical defect that this nitrogen sealing water channel exists is exactly: according to the use amount of back segment pure water, the liquid level in pure water constantly changes, and a large amount of nitrogen is drained in air, and the nitrogen consumption is large, thereby makes over-the-road expense higher.
The utility model content
Technical problem to be solved in the utility model is, the shortcoming existed for above prior art proposes a kind ofly have nitrogen seal device pure water holding vessel, in the situation that guarantee pure water water quality, reduces or approximate zero consumes nitrogen.
A kind of intelligent nitrogen-sealed water tank, comprise water tank, nitrogen capsule, pressure sensor, pressure gas source, air inlet electromagnetic valve and exhaust solenoid valve; The input end of described air inlet electromagnetic valve is connected with described pressure gas source, the mouth of described air inlet electromagnetic valve with for being connected described water tank, with the connecting tube of described nitrogen capsule, be connected; The input end of described exhaust solenoid valve is connected with described water tank, and the mouth of described exhaust solenoid valve is communicated with outside atmosphere; Described pressure sensor is arranged on described water tank, and for detection of the pressure in described water tank.
Good effect of the present utility model is: the utility model is realized water pot nitrogen envelope, and nitrogen can only not need in regularly past air bag to supplement a little nitrogen to get final product because being discharged into air loss, can greatly reduce the consumption of nitrogen, saves operating cost.
The accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, in below describing the utility model, the accompanying drawing of required use is briefly described.
Fig. 1 is the structural representation of a kind of intelligent nitrogen-sealed water tank of providing of the utility model embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Please refer to Fig. 1, Fig. 1 is the structural representation of a kind of intelligent nitrogen-sealed water tank of providing of the utility model embodiment.In the present embodiment, this device comprises water tank 1, nitrogen capsule 2, pressure sensor 3, pressure gas source 4, air inlet electromagnetic valve 5, exhaust solenoid valve 6 and control circuit.The input end of air inlet electromagnetic valve 5 is connected with pressure gas source 4, the mouth of air inlet electromagnetic valve 5 with for being connected water tank 1, with the connecting tube of nitrogen capsule 2, be connected.The input end of exhaust solenoid valve 6 is connected with water tank 1, and the mouth of exhaust solenoid valve 6 is communicated with outside atmosphere.Pressure sensor 3 is arranged on water tank 1, and for detection of the pressure in water tank 1.
This control circuit comprises Programmable Logic Controller and data acquisition module, the input end of data acquisition module is electrically connected to the mouth of pressure sensor 3, the mouth of data acquisition module is connected with Programmable Logic Controller, and Programmable Logic Controller is electrically connected to the control end of air inlet electromagnetic valve 5 and exhaust solenoid valve 6 respectively.
Pressure gas source 4 is high-pressure nitrogen bottle.
This device is when real work, and when water tank 1 high liquid level, air inlet electromagnetic valve 5 is opened, and pressure gas source 4 will supplement nitrogen in nitrogen capsule 2 by induction tract; When water tank 1 low liquid level, air inlet electromagnetic valve 5 is closed, and nitrogen capsule 2 will supplement nitrogen in water tank 1 by induction tract; When the interior liquid level of water tank 1 changes, nitrogen circulates between nitrogen capsule 2 and water tank 1, realize the nitrogen envelope of water tank 1, but nitrogen can be because not being discharged into air loss, thereby realize the isolated of pure water and outside air in order to avoid reduced the consumption of nitrogen when polluting, save operating cost.Inlet open when the tank internal pressure is less than the safety low-pressure of setting, when the tank internal pressure is greater than the safety high-pressure of setting, blow off valve is opened, with the support system equilibrium of pressure.
Good effect of the present utility model is: by pressure sensor and acquisition module, carry out the actual pressure value in inspection instrument, and come the control presssure source of the gas to adjust the force value in container by Programmable Logic Controller, thereby realize the isolated in order to avoid pollute of ultra-pure water and outside air, of the present utility model simple in structure, the storage effect is better, and greatly reduce the consumption of nitrogen, cut operating costs.
For casehistory realization of the present utility model, the above-mentioned specific embodiment has been described.But other variations of the present utility model and modification; be apparent for those skilled in the art, any modification in essence disclosed in the utility model and fundamental principle scope/variation or imitation conversion all belong to claim protection domain of the present utility model.
