Description

The molten gas automatic control device of molten cylinder

The utility model relates to the molten gas automatic control device of the molten cylinder of using in a kind of water treatment field of purification.

In recent years, because the discharging of trade effluent and sanitary sewage, most of river water source severe contamination, has flavor, greasy dirt at the water quality blackout, as drinks the water of taking from polluted source and will directly be detrimental to health.Original water treatment method can not satisfy the requirement of people's drinking water quality.Thereby aspect sewage disposal, adopt air-float technology to handle mostly, and promptly in water, feed or produce a large amount of micro bubbles, it is adhered on the impurity wadding grain, cause the state of whole proportion less than water, and rely on buoyancy to make its floating water surface of going up, and separate thereby obtain solid, liquid, reach the purpose of purification.As disclosed high-effective sewage purifying device in Chinese patent 9322072B, this device comprises that injecting dissolve gas device, air supporting part are from cylindrical shell, sludge bucket, mud scraper, sump pump; This device is that air supporting, precipitation, filtration three big technology are integrated in one, and the sewage after its primary treatment can reach country and local pollution exhaust criteria fully.A kind of multifunctional water purifier is disclosed in Chinese patent 93202569 in addition, comprise air-flotation reactor and the filtration chamber that is positioned at its underpart, be provided with aeration coagulation basin and coagulating agent case on cleaner top, and aeration sterilization pool and disinfectant solution tank, this device gas collection floats water purification, aeration, sterilization, sterilization, is filtered into one, have simple in structurely, treatment capacity is big, purification efficiency height, the characteristics that water quality is good.Automatic control of molten cylinder is to adopt water yield control as another.Water yield control can't be guaranteed the dissolved-air rate in the water, generally only is 60%, and power consumption is high.

The purpose of this utility model is to utilize molten cylinder water level just to control compressor operation in order to provide a kind of, thereby can guarantee abundant molten gas in the water, and its dissolved-air rate can be increased to 90%, power consumption is little, power saving, the molten gas automatic control device of molten cylinder simple in structure.

The purpose of this utility model can realize by following measure:

The molten gas automatic control device of a kind of molten cylinder; Be provided with the upper and lower limit level electrode at molten cylinder sidewall, and link by electrode and molten gas automatic control circuit; Molten gas automatic control circuit is to be associated with bridge rectifier circuit on the limit of paying of supply transformer, and bridge rectifier circuit is parallel with capacitive branch, the upper and lower limit water level signal is amplified branch road; Wherein, upper and lower limit water level signal amplification branch road is respectively at triode T ₁, T ₂Base stage pass through resistance R ₁, R ₁Link triode T with the upper and lower limit level electrode ₁, T ₂Collector electrode respectively be parallel with diode D ₁, D ₂Upper and lower limit level relay JA ₁, JA ₂Coil link; Other is in series with SB between the two-phase power supply line of the air compressor motor of molten cylinder ₁, SB ₂The normally opened contact KA of air compressor motor power control relay coil JM, overheat switch FR, lower limit level relay ₂SB ₁On be parallel with air compressor motor relay normally opened contact KM and upper limit level relay normally opened contact KA ₁

The utility model has following advantage compared to existing technology:

1, the utility model is provided with the upper and lower limit level electrode in molten cylinder, utilizes the break-make of level electrode to control the break-make of air compressor machine, thereby can guarantee water molten gas of abundant ventilation more than the water level upper limit in the molten cylinder, guarantees that dissolved-air rate reaches 90% in the water.

2, the novel circuit of this reality guarantees that the running of air compressor machine controls by water level, the bad operation when having avoided molten cylinder water level low, thereby power saving, energy-conservation.

3, the utility model stable performance, reliable, easy to make, cost is low.

The utility model concrete structure is provided by the following drawings:

Fig. 1 is a structure electrical principle synoptic diagram of the present utility model:

The molten cylinder 2-of 1-lower limit level electrode 3-upper limit level electrode

The 4-air compressor motor

The utility model is also incited somebody to action in conjunction with the accompanying drawings, and 1 embodiment is described in further detail:

With reference to Fig. 1, the molten gas automatic control device of a kind of molten cylinder; Be provided with upper and lower limit level electrode 3,2 at molten cylinder 1 sidewall, and link by electrode 3,2 and molten gas automatic control circuit; Molten gas automatic control circuit is to be associated with bridge rectifier circuit on the limit of paying of supply transformer, and bridge rectifier circuit is parallel with capacitive branch, the upper and lower limit water level signal is amplified branch road; Wherein, upper and lower limit water level signal amplification branch road is respectively at triode T ₁, T ₂Base stage pass through resistance R ₁, R ₁Link triode T with upper and lower limit level electrode 3,2 ₁, T ₂Collector electrode respectively be parallel with diode D ₁, D ₂Upper and lower limit level relay JA ₁, JA ₂Coil link; Other is in series with SB between the two-phase power supply line of the air compressor motor 4 of molten cylinder 1 ₁, SB ₂The normally opened contact KA of air compressor motor power control relay coil JM, overheat switch FR, lower limit level relay ₂SB ₂On be parallel with air compressor motor relay normally opened contact KM and upper limit level relay normally opened contact KA ₁

Principle of work of the present utility model is as follows:

When the water level of molten cylinder 1 was lower than lower limit level electrode 2, air compressor motor 4 was not worked.When molten cylinder 1 water level arrives lower limit level electrode 2, triode T ₂Conducting, relay J A ₂Coil electricity, make its normally opened contact KA ₂Adhesive; When water level arrives upper limit level electrode 3, triode T ₁Conducting, relay J A ₁Coil electricity is often opened it and is touched KA ₁Adhesive, at this moment, the coil electricity of air compressor motor 4 relay JM makes its power switch of its adhesive KM, thus air compressor motor 4 runnings.
