Description
Technical field
The present invention relates to oil-gas mining safety control technology fields, and in particular to a kind of free of contamination safe petroleum tank.
Background technology
Existing crude oil storage tank is in operation, it is necessary to field observation liquid level, control electrical heating and oil-well motor control manually
Device, such as operation not in time, are susceptible to security incident, particularly winter, do not start electric heater unit in time such as, be easy to cause
Crude oil is congealed in tank, and the accidents such as oil are run in pipeline bursting by freezing.When the liquid level in crude oil storage tank reaches the safety levels upper limit, if not and
Shi Faxian be easy to cause crude oil storage tank tank boil-overs accident；When the liquid level in crude oil storage tank reaches safety levels lower limit, if not and
Shi Faxian be easy to cause heating unit dry combustion method and triggers fire incident.
The patent of invention that number of patent application is 201420365658.8 discloses a kind of crude oil storage tank safety control, institute
It states crude oil storage tank to be arranged between crude oil storage tank, distribution box, electric heater unit and oil-well motor with safety control, the original
Buoy is equipped in oil tank, the electric heater unit and the oil-well motor are connected with the distribution box, the security control dress
It puts including liquid level gauge and driving member, the liquid level gauge includes Liquid level scale cylinder and the copper inside the Liquid level scale cylinder
Hammer, upper magnetic sheet, lower magnetic sheet, upper magnetic attraction switch and lower magnetic attraction switch, the "painted-face" character in opera by the driving member with it is described
Buoy is connected, and the upper magnetic sheet and the lower magnetic sheet are mounted on the "painted-face" character in opera, and the upper magnetic attraction switch adds with the electricity
Thermal is connected, and the lower magnetic attraction switch is connected with the oil-well motor.When liquid level reaches the safety levels of crude oil storage tank
During lower limit, by the movement of "painted-face" character in opera, magnetic sheet is attracted with upper magnetic attraction switch in drive, controls electric heater unit circuit from dynamic circuit breaker
It opens, stops electrical heating, avoid oil-free electrical heating dry combustion method in crude oil storage tank；When liquid level rises to the safety levels upper limit of crude oil storage tank
When, it being moved by "painted-face" character in opera, lower magnetic sheet is driven to be attracted with lower magnetic attraction switch, control oil-well motor circuit disconnects automatically stops well,
