CN2403733Y - Automatic controller for oil tank dewatering - Google Patents

Abstract

The utility model relates to an automatic controller of oil tank dewatering. The utility model is characterized in that the bottom of an oil storage tank is connected with a secondary dewatering tank, a water oil separation board is arranged on the upper part of the secondary dewatering tank, the lower part is provided with a heat accompanying tube, a floating ball, a matching block and a limiting board are arranged on the middle part of a water discharging control valve, one end of the floating ball is provided with a connecting rod and a magnetic steel, and a magnetic steel with the same polarity is arranged outside the secondary dewatering tank. The magnetic action causes the action of the floating ball to control the process of the level drainage through the magnetic steel which causes a response bar and a proximity switch to sent out corresponding signals. An oil water detector gives the double protection of an alarm and the automatic control in the process of the dewatering and the automatic control, when the drainage water comprises a certain oil component.

Description

The oilcan dehydration automatic control device

The utility model relates to the oilcan dehydration technology, belongs to the automatic control device that oil tank is realized second dehydration specifically.At present general oil product is stored in the oil tank, contain certain moisture content in the oil product, through the regular hour, the heavy hall of moisture content is in the oil tank bottom, the general moisture content that adopts in the manual method eliminating oil tank, in drainage procedure, normal band portion oil product runs off, cause energy loss to a certain extent, environment is brought pollution.Artificial simultaneously dehydration work capacity is big, as untimely dehydration, influences oil quality again.

The purpose of this utility model provides a kind of oil tank and realizes second dehydration, and implements automatic guidance, ensures oil quality, energy savings, a kind of oilcan dehydration automatic control device of protection ring environment pollution.

For finishing the technical scheme that this goal of the invention is taked, hand valve is passed through in the bottom of petrol storage tank, metallic hose, filter connects the top of second dehydration jar, water, oil separation plate are set in the top of second dehydration jar, trace pipe and sewage draining exit are established in the bottom, establish a ball float at the middle part of second dehydration jar, clump weight and spacing regulating plate.One side of ball float is established a connecting rod, and an end of this connecting rod is put a magnet steel.A response bar is established in the outside of water knockout, and a magnet steel is established at response bar middle part.Two magnet steel polarity are inhaled each other mutually, establish two near switch in two terminals of the upper and lower swing of response bar.Connect relay and electromagnetic valve near switch, the second dehydration pot bottom establish a normally closed operated pneumatic valve and electromagnetic valve supporting.And connecting a hand valve, a profit detector is installed in the exit.

The utility model can in time dewater, and increases the oil tank storage capacity, guarantees oil quality.Automatic guidance reduces operator's work capacity, reduces oil product in the past because operation is former thereby cause to a certain degree loss, for energy savings provides good equipment, simultaneously very big effect is played in environmental protection.

The utility model embodiment is described in detail in conjunction with the accompanying drawings.

Fig. 1 is the utility model constructional drawing.

According to shown in Figure 1, the bottom of petrol storage tank is by hand valve 2, flexible pipe 3, filter 4 connect second dehydration jar 5 tops, second dehydration jar 5 internal upper parts are provided with a water oil separation plate 6, oil product enters second dehydration jar 5, because the effect of water oil separation plate 6, the oil water mixture that enters is entered by second dehydration jar 5 surrounding walls, oil product floats naturally, is convenient to oil product and refluxes.Adorn a ball float 10 by connecting rod 12 suspensions in the middle of the second dehydration jar 5, an end establishing pouring weight 9 of ball float is to adjust the density contrast of various oil products.Deploy a spacing regulating plate 11 in the connecting rod 12.Ball float floats between oil, the water termination, and when water level improved, ball float 10 was because the also corresponding rising of density of water.Establish a magnet steel 13 with the other end of ball float 10 bonded assembly connecting rods 12, another magnet steel 15 is established in second dehydration jar 5 outsides, and is installed on the response bar 17.Two blocks of magnet steel 13 and 15 polarity are identical and inhale mutually mutually.Cause secondary in taking off not jar magnet steel 13 since ball float 10 knee-actions attract the magnet steel 15 in the second dehydration jar outside and respond bar to make corresponding action.The upper and lower swing of the one end dead point of response bar 17 is installed two near switch 14,18, connect electromagnetic valve 20 and normally closed pneumatic valve 21 near the electric signal of switch 14,18 by relay, and normally closed pneumatic valve 21 also connects a hand valve 16.One end of normally closed pneumatic valve 21 is put a hand valve 19, and is connected with second dehydration jar 5.The other end passes through a profit detector 22 to outlet 23.Above-mentioned mainly is to control normally closed pneumatic 21 by electromagnetic valve 20 to open or close near switch 14,18.Profit detector 22 detects mouth of a river discharge opeing in drainage procedure or when the normally-closed pneumatic valve cuts out be water or oil.As when detecting the discharge port discharge opeing and containing the composition of a certain proportion of oil, this detector promptly sends extremely alert and SELF CL normally-closed pneumatic valve 21, and trace pipe 7 and blowdown plug 8 are established in above-mentioned second dehydration jar 5 bottoms, heat when wherein trace pipe 7 is for winter low temperature and protect heat usefulness.And blowdown plug 8 blowdown effect when being used to clean.
