Since the fan screen 310, the first mesh screen 320 and the auxiliary mesh screen 440 are all permeable, both liquid oil and water can pass through the fan screen 310, the first mesh screen 320 and the auxiliary mesh screen 440, and thus the resistance when the fan screen 310 contacts the liquid oil is small. As the driving rod 210 slides further downward, the mounting ring 250 drives the sector net 310, the first net plate 320 and the auxiliary net plate 440 to slide downward synchronously, and the auxiliary net plate 440 cuts the solid petroleum, so that when the solid petroleum contacts the sector net 310, the contact state between the solid petroleum and the sector net 310 can reduce the permeability of the sector net 310, and the resistance applied when the driving rod 210 slides downward increases. In the initial state, the fan-shaped net 310 is in a horizontal state, the auxiliary net plates 440 connected to two adjacent fan-shaped nets 310 are abutted against each other, and the first springs 340 are in an original length state, and under the action of the first springs 340, the first net plates 320 are abutted against the auxiliary net plates 440, so that when the fan-shaped net 310 contacts with solid petroleum, the resistance of the solid petroleum to the fan-shaped net 310 is insufficient to drive the fan-shaped net 310 and the driving rod 210 to slide relatively.
As the driving rod 210 slides further downwards, the driving rod 210 drives the fan-shaped net 310 to completely enter the water layer, the lower end of the driving rod 210 gradually enters the limiting ring 410, and the driving rod 210 and the mounting ring 250 slide relatively under the further driving of the driving motor 230 because the outer diameter of the limiting ring 410 is smaller than the outer diameter of the mounting ring 250. The driving wheel 420 installed on the mounting ring 250 slides along the first driving groove 212 on the side wall of the driving rod 210, a first rack and a second rack are respectively arranged on two opposite side walls of the first driving groove 212, in the sliding process of the driving wheel 420 along the first driving groove 212, the driving wheel 420 is alternately meshed with teeth on the first rack and teeth on the second rack, the driving wheel 420 rotates positively and negatively alternately, the rotating shaft of the driving wheel 420 is fixedly connected with the inner arc section of the sector net 310, and the sector net 310 deflects synchronously.
When the fan-shaped net 310 deflects clockwise, as shown in fig. 7, the radii of two edges of the fan-shaped net 310 are respectively at the left end and the right end, when the fan-shaped net 310 deflects clockwise, the left end of the fan-shaped net 310 deflects upwards, the right end of the fan-shaped net 310 deflects downwards, one auxiliary screen plate 440 at the left end of the fan-shaped net 310 is abutted against the side wall of the auxiliary screen plate 440 at the right end of the adjacent fan-shaped net 310, a first screen plate 320 near the left end of the fan-shaped net 310 slides along an arc groove under the extrusion of the auxiliary screen plate 440, and meanwhile, a first screen plate 320 near the right end of the adjacent left fan-shaped net 310 slides along the arc groove under the extrusion of the auxiliary screen plate 440, so that two first screen plates 320 on the same fan-shaped net 310 slide along the arc groove at the same time; with the deflection of the fan-shaped net 310, the auxiliary net plate 440 at the left end of the fan-shaped net 310 is extruded by the edge radius of the adjacent fan-shaped net 310, the first net plate 320 near the left end of the fan-shaped net 310 is further extruded by the auxiliary net plate 440, at this time, a certain included angle is formed between the auxiliary net plate 440 at the right end of the fan-shaped net 310 and the first net plate 320, at this time, the deflection of the two auxiliary net plates 440 near each other by the adjacent two fan-shaped net 310 generates obstruction, at this time, the first net plate 320 near the right end of the fan-shaped net 310 cannot be reset, at the same time, the side wall of the first net plate 320 near the right end of the fan-shaped net 310 is abutted to the limit stop lever 430 in the process of sliding along the arc groove, the limit stop lever 430 can obstruct the first net plate 320 from excessively sliding, at this time, the interval between the two first net plates 320 is reduced in the process of sliding along the arc groove, at this time, solid petroleum between the two first net plates 320 is extruded, and liquid petroleum doped in the solid petroleum is extruded. While liquid petroleum below the solid petroleum layer flows upward through the first screen 320 and the auxiliary screen 440 as the fan screen 310 is deflected to an inclined state, gradually mixing with the liquid petroleum at the uppermost layer.
When the driving wheel 420 rotates alternately clockwise and counterclockwise, the fan-shaped net 310 rotates alternately clockwise and counterclockwise synchronously, so that the two first net plates 320 slide alternately along the arc grooves, and the inclination of the fan-shaped net 310 changes alternately in opposite directions, thereby ensuring that the liquid petroleum doped in the solid petroleum is completely separated, and simultaneously ensuring that part of the liquid petroleum layer below the solid petroleum layer can flow upwards completely.
When the driving wheel 420 slides to the end of the first driving groove 212, the air pump communicated with the second opening 114 is started at this time, and the air pump pumps the gas in the detection cavity 111 above the plugging disc 120, so that the plugging disc 120 slides upwards synchronously, and when the pressure below the plugging disc 120 decreases, the solubility of the gas petroleum in water decreases, and the gas petroleum dissolved in water is gradually separated out. Then the driving motor 230 is started to reversely rotate, the power output shaft of the driving motor 230 drives the driving rod 210 to slide upwards, the driving rod 210 gradually pulls the fan-shaped net 310 to restore to the initial position, and then the solid petroleum synchronously floats upwards. At this time, a certain distance is provided between the plugging disc 120 and the fan-shaped net 310, gas oil is contained between the distances, the content of the gas oil is calculated according to the distance between the plugging disc 120 and the fan-shaped net 310, the gas oil is observed through an observation window, and is calculated according to scale marks on the plugging plate, a plurality of groups of detection data are subjected to comparative analysis, and an effective solution is specified according to the calculated data, so that the pollution treatment effectiveness is ensured, and the waste of resources is reduced.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
