Referring to fig. 1-3, the oil-water separation continuous working device comprises a rotary table 1 and a mixing tank 2, wherein petroleum extracted from an oil field is directly led into the mixing tank 2, the bottom of the mixing tank 2 is hermetically and slidably connected with a tank bottom 3, and the side wall of the mixing tank 2 is fixedly connected with an external support so as to ensure that the mixing tank is stable in position;

a motor 16 is concentrically welded and fixed at the lower end of a rotary table 1, a plurality of separation pools 4 are annularly arranged on the rotary table 1, a feeding pipe 5 penetrates through the middle part of the upper end of each separation pool 4 and is welded and fixed in a sealing manner, each feeding pipe 5 is welded and fixed with a tank bottom 3, oil in a mixing tank 2 can enter the separation pools 4 through the feeding pipe 5, a round rod 6 is welded at the middle part of each separation pool 4, a follow-up device is connected onto the round rod 6 in a penetrating and sliding manner, a power box 11 is arranged at the middle part of the lower end of each separation pool 4 in a sealing manner, an oil pipe 12 and a water pipe 13 are welded and connected at the lower end of the power box 11 in a sealing manner, a first annular pool 14 and a second annular pool 15 are arranged at the lower end of the rotary table 1, the first annular pool 14 is positioned inside the second annular pool 15, the oil pipe 12 penetrates through the separation pools 4 and is communicated with the first annular pool 14, the water, during the rotation of the rotary table 1, the oil pipe 12 and the water pipe 13 are always positioned in the first annular pool 14 and the second annular pool 15 because the two annular pools are annular structures.

The follow-up device comprises a floating block 7, the density of the floating block 7 is between water and oil, the floating block 7 is sleeved on a round rod 6, a first bent pipe 8 and a second bent pipe 9 are fixedly connected onto the floating block 7 through pipe clamps, the first bent pipe 8 is located at the oblique upper corner close to the rotary table 1, the second bent pipe 9 is located at the oblique lower corner far away from the rotary table 1, when the rotary table 1 rotates to enable the oil and the water in the separation tank 4 to be quickly layered, the oil is located on one side, close to the circle center of the rotary table 1, of the separation tank 4, the density of the water is higher than that of the oil and located on the other side of the separation tank 4, and the combined action of gravity and centrifugation is considered at the same time, the two bent pipes are located at two oblique corners of the.

The power box 11 internal fixation has water pump and oil pump, the input of water pump passes through hose 10 and the 9 veneer intercommunications of second return bend, the output and the 13 veneer of water pipe intercommunication of water pump, the input of oil pump passes through hose 10 and the 8 sealed intercommunication of first return bend, the output and the 12 veneer of oil pipe intercommunication of oil pump, the operating power of oil pump and water pump keeps unanimous, when the hose 10 state that links to each other with two pumps is unanimous, the liquid volume that oil pump and water pump unit interval carried is roughly equal, guarantee that two kinds of liquid are by even transport to two annular ponds in the separation tank 4.

A nylon rope 17 is glued and fixed on one side of the floating block 7 close to the power box 11, a sliding groove 18 is arranged on one side of the power box 11 close to the floating block 7, a sliding block 19 is connected on the sliding groove 18 in a sliding manner, two sides of the sliding block 19 are respectively welded with a spring 21, one end of each spring 21 far away from the sliding block 19 is respectively welded on the inner wall of the sliding groove 18, a partition plate 20 is welded and fixed on the sliding block 19, when the amount of the two liquids in the separation tank 4 is not 1:1, the floating block 7 slides on the round bar 6 to drive the partition plate 20 to move to press the hose 10 on one side, the pressed hose 10 is deformed to reduce the cross-sectional area, when the pump body in the power box 11 works at a certain power, the amount of liquid connected with the pumping deformation hose 10 is reduced, and the speed of pumping the liquid on the other side into the annular tank is higher than that on the other side, so that the ratio difference between the oil and the water in the separation tank 4 is not too large, and the phenomenon that the other liquid is mixed into the two bent pipes is avoided.

In the invention, the motor 16 works to drive the turntable 1 to rotate to drive the separation tank 4 thereon to rotate at a high speed, when oil mixed with water rotates along with the turntable in the separation tank 4 at a high speed, water and the oil in the separation tank 4 are quickly layered, and the density of the floating block 7 is between the water and the oil, so the floating block 7 is positioned at an oil-water boundary; the pipe orifice of the first elbow pipe 8 is in oil, the pipe orifice of the second elbow pipe 9 is in water, and the water pump and the oil pump in the power box 11 are started, so that the liquid in the two elbow pipes is pumped into the second annular pool 15 and the first annular pool 14, and the oil-water separation work is completed.

When the mixing ratio of oil and water is about 1:1, the floating block 7 is positioned in the middle area of the round rod 6, the nylon rope 17 does not generate a pulling effect on the sliding block 19 at the moment, the sliding block 19 can be positioned in the middle of the sliding groove 18 due to the fact that the springs 21 on the two sides of the sliding block 19 are completely consistent, the partition plate 20 is not in contact with the two hoses 10 at the moment, the water pump and the oil pump in the power box 11 work at the same power, the amount of water and petroleum conveyed by the two pumps in the same time is approximately equal in the state, and the floating block 7 can be kept near the initial position and continuously works;

when the mixing ratio of oil and water is not 1:1, the floating block 7 deviates from the middle area of the round rod 6 and slides to a certain side, at the moment, the floating block 7 generates a traction effect on the nylon rope 17, the slider 19 is pulled to have a tendency of moving to a certain side along with the floating block 7, when the slider 19 slides to enable the partition plate 20 to abut against the hose 10 and deform the hose 10, the cross section of the hose 10 is reduced, namely the liquid amount passing through the deformed hose 10 in the same time is reduced, the liquid flow in the other hose 10 is kept unchanged, and further the liquid pumping amount of the water pump and the oil pump is changed, when the water in the separation tank 4 is obviously more than the oil, the floating block 7 moves to a side close to the center of the rotary table 1, the partition plate 20 moves along with the hose 10 to deform, so that the liquid amount delivered by the oil pump in unit time is larger than that of the water pump, and further the speed of the oil in the separation tank 4 entering the first annular tank 14 is larger than that of, gradually keeping the oil-water ratio in the separation tank 4 at 1:1, avoiding the phenomenon that the quantity difference between the oil and the water in the separation tank 4 is large, so that the other liquid is mixed in the two bent pipes. The oil-water separation effect is ensured to be better.

When two pumps in the power box 11 pump out the liquid in the separation tank 4, negative pressure can be generated in the separation tank 4, and then the oil-water mixture in the mixing box 2 can rapidly enter the separation tank 4.

Although the terms of the turntable 1, the mixing box 2, the box bottom 3, the separation tank 4, the feeding pipe 5, the round bar 6, the floating block 7, the first elbow 8, the second elbow 9, the hose 10, the power box 11, the oil pipe 12, the water pipe 13, the first annular tank 14, the second annular tank 15, the motor 16, the nylon rope 17, the sliding groove 18, the sliding block 19, the partition plate 20, the spring 21, etc. are used more frequently, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed as being without limitation to any additional limitations that may be imposed by the spirit of the present invention.
