Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The embodiment relates to a water-oil-sand three-phase separation device for separating a stock solution mixed with water, oil and sand into a sand body, treated oil and treated water, as shown in figures 1 and 5, the water-oil-sand three-phase separation device comprises a rotational flow component 1, an inflow pipe 2 which is communicated with the rotational flow component 1 and forms the raw liquid to flow into the rotational flow component 1, and a driving unit which is connected with the rotational flow component 1 in a driving way, the driving unit can drive the rotational flow component 1 to rotate around the axial line of the rotational flow component 1 so as to separate the sand body from the mixed liquid of oil and water, the water-oil-sand three-phase separation device also comprises a sand body collecting unit 3 which is fixedly arranged at the bottom of the rotational flow component 1 and is used for sand body to flow in, and a mixed liquid outlet pipe 4, the mixed liquid outflow pipe 4 can introduce the oil-water mixed liquid separated by the cyclone unit 1 into the mixed liquid separation unit 5, and the mixed liquid separation unit 5 separates the mixed liquid into treated water and treated oil.

Specifically, as shown in fig. 1, the cyclone assembly 1 specifically includes a cylindrical portion 11, a conical portion 12 and a connecting portion 13 which are sequentially connected from top to bottom, wherein the cylindrical portion 11 and the connecting portion 13 are both cylindrical, and the raw liquid flowing into the cyclone assembly 1 through the inflow pipe 2 rotates inside the cyclone assembly 1, and due to the difference in density of water, oil and sand in the raw liquid, the centrifugal force generated by the rotation of the raw liquid in the cyclone assembly 1 can cause sand with a large specific gravity to face outward and settle along the inner wall of the conical portion 12, and then the sand flows into the sand recovery unit through the connecting portion 13. The rotational flow component 1 can rotate by being driven by a driving unit, the driving unit is not shown in the figure, one mode of driving the rotational flow component 1 to rotate by the driving unit is as follows, the driving unit is a motor, a first synchronizing wheel is fixedly arranged on an output shaft of the motor, a second synchronizing wheel is fixedly arranged on the periphery of the connecting part 13, and a synchronous belt is connected between the first synchronizing wheel and the second synchronizing wheel so as to drive the rotational flow component 1 to rotate by the motor; of course, the drive unit can drive the rotational flow component 1 to rotate in other manners, such as a chain wheel transmission or a gear transmission between the motor and the rotational flow component 1.

In order to accelerate the settling velocity of the sand, as shown in fig. 1 and fig. 2, in the present embodiment, a plurality of baffles 121 are uniformly distributed on the inner wall of the conical portion 12 and are obliquely arranged along the rotation direction of the cyclone assembly 1; by arranging the baffle 121, as shown in fig. 4, since the direction of the centrifugal force is tangential to the rotation direction of the sand body, when the rotation speed is high, the settling velocity of the sand body is slow, and by arranging the baffle 121, the centrifugal force and the supporting force of the baffle 121 to the sand body can form a downward resultant force, so that the settling velocity of the sand body can be effectively increased, and the separation efficiency of the sand body and the oil-water mixed liquid can be improved.

As is known, the higher the rotation speed of the cyclone assembly 1 is, the better the separation effect of the sand and the oil-water mixture is, but the too high rotation speed can cause the separated sand to be partially involved in the oil-water mixture, and in order to reduce the sand from being re-involved in the mixture, in this embodiment, as shown in fig. 1, the mixture outlet pipe 4 includes a pipe head fixed inside the connection portion 13 and a pipe body connected to the pipe head and extending downward, and the pipe head is preferably in an inverted cone shape, and further preferably, the pipe head is arranged concentrically with the connection portion 13, and by providing the pipe head, not only the oil-water mixture can be discharged, but also the outer wall of the pipe head can effectively prevent the separated sand from being involved in the mixture again, and the separation effect of the sand and the mixture can be effectively improved.

An effective fixing of the pipe head to the inner wall of the connecting part 13 is that, as shown in fig. 3, a plurality of connecting plates are provided between the pipe head and the inner wall of the connecting part 13, sand can flow into the sand recovery unit through the gaps between the connecting plates,

foretell mixed liquid separation subassembly 5 is including being formed with the casing that holds the chamber, and holds the chamber and be linked together with the body, arranges at least a set of oil interceptor 51 that will hold the chamber and separate into a plurality of cavities in holding the intracavity, and the top of each oil interceptor 51 is higher than the liquid level that holds the mixed liquid of intracavity, and the bottom intercommunication of each cavity accessible oil interceptor 51.

In the present embodiment, the oil separation plate 51 is a single plate and divides the accommodating cavity into a first chamber 501 and a second chamber 502, wherein the first chamber 501 is communicated with the pipe, the density of the mixed liquid flowing into the first chamber 501 is different from that of the water and the oil, and the density of the oil is less than that of the water, so the oil floats upwards, the water sinks, and the first chamber 501 is communicated with the second chamber 502 at the bottom, so the separated water can enter the second chamber 502 and be discharged through the water recovery port 53 at the bottom 502 of the second chamber, and the oil at the top of the first chamber 501 can be recovered through the oil recovery port 54 arranged at the first chamber 501.

In order to improve the oil-water separation rate by making the mixed liquid rotate in the cyclone assembly 1 to separate the water and the oil into layers, in this embodiment, as shown in fig. 1 and 5, the pipe head specifically includes an inner pipe head 42 and an outer pipe head 41 which are nested with each other, and the pipe body includes an outer pipe 43 connected to the outer pipe head 41 and an inner pipe 44 connected to the inner pipe head 42, and through the centrifugal analysis, since the oil has a density lower than that of the water, the oil is concentrated in the center of the cyclone assembly 1 and mainly flows into the mixed liquid separation assembly 5 through the inner pipe 44, and the water is concentrated between the oil and the sand and mainly flows into the mixed liquid separation assembly 5 through the outer pipe 43. For this reason, in the present embodiment, the outer tube 43 is configured to communicate with the receiving cavity, specifically the bottom of the first chamber 501, and the inner tube 44 is configured to communicate with the receiving cavity, specifically the top of the first chamber 501, and since the inner tube 44 mainly contains oil and the outer tube 43 mainly contains water, the inner tube 44 and the outer tube 43 are configured as above, which can significantly improve the separation efficiency of oil and water.
