Along with the gradual change of impurity on the filter screen 3, the waste water that intake groove 2 department flowed into also can constantly strike impurity, impurity can remove to slag hole 27 department, fall to the guide slag groove 29 at last, when the profit passed filter screen 3, some profit can be continuous strike water collector 31 department, water collector 31 can the luffing motion after receiving the impact of profit, drive horizontal pole 30 simultaneously and take place the swing from pivot 32, horizontal pole 30 also can drive guide slag groove 29 shake when luffing motion, guide slag groove 29 shake the slope of the inside impurity of being convenient for along guide slag groove 29 bottom rolls, in addition horizontal pole 30 left end to the distance ratio of pivot 32 to horizontal pole 30 right-hand member to pivot 32 is 1:5, a labor-saving lever is realized, and the slag guide groove 29 is driven to shake under the impact of oil water.
As shown in FIG. 3, the left ends of the filter screen 3 and the heating plate 4 are inclined downwards by 15 degrees, so that impurities can roll down along the filter screen 3, the problem that the inclination amplitude of the filter screen 3 is large, waste water flows along the gradient of the filter screen 3 and finally flows out from the slag discharging hole 27 can be avoided.
Working principle: firstly, waste water is injected from a water inlet tank 2, the waste water flows onto a filter screen 3 along the water inlet tank 2, a heating plate 4 is electrified to heat the filter screen 3 to a proper temperature, solid grease in the waste water is gradually melted when contacting with the heated filter screen 3 and is mixed with water to pass through the filter screen 3 and a water permeable hole 5, oil water flows onto a gradient plate 9 and is discharged to the lower side along a water discharge cylinder 6, water is initially filled in the shell 1, the water level is arranged at the position where a water discharge pipe 8 is arranged, the liquid level of the water in the shell 1 and the oil water are combined, when the water level in the shell 1 is higher than the water discharge pipe 8, a sealing block 26 is lifted along with the water level, the opening of the water discharge pipe 8 is opened, the water can be discharged from the water discharge pipe 8, the sealing block 26 is also moved downwards after the water level is lowered, finally, the drain pipe 8 is closed, so that oil is prevented from being discharged from the drain pipe 8, the oil level is higher than the oil discharge pipe 7 and is discharged along the oil discharge pipe 7, oil-water separation is realized, oil water discharged from the lower end of the drain cylinder 6 enters the sleeve 10, the buoyancy of the oil is larger than that of water, the oil can rapidly rise in the sleeve 10 and is discharged from the oil discharge pipe 7, the oil-water separation efficiency is greatly improved, the efficiency is improved, the problem that the oil is solidified in the shell 1 for a long time can be avoided, the lower end of the drain cylinder 6 is 1.5m away from the lower end of the sleeve 10, the problem that the oil discharged from the lower end of the drain cylinder 6 is impacted to the bottom of the sleeve 10 and finally escapes from the sleeve 10 from the bottom can be avoided;
when water in the sleeve 10 flows out from the lower end, the water flows to the static column 17, static electricity is generated by electrifying the static column 17, tiny impurities in the wastewater are adsorbed after the static column 17 generates static electricity, the wastewater is purified in one step, the purification effect of the wastewater is improved, the umbrella-shaped cover 18 can also adsorb the tiny impurities in the water after electrifying the static column 17, when the surfaces of the umbrella-shaped cover 18 and the static column 17 are fully adsorbed with the tiny impurities, the overall weight of the umbrella-shaped cover 18 and the static column 17 is increased, the umbrella-shaped cover 18 and the static column 17 downwards squeeze the mounting plate 19, meanwhile, the connecting block 20 moves downwards together with the first conductive block 22, in addition, the first conductive block 22 is electrically connected with the static column 17, the second conductive block 23 is connected to the circuit of the electrostatic column 17, when the first conductive block 22 moves downwards, the left and right sides of the first conductive block 22 are not contacted with the second conductive block 23, the circuit of the electrostatic column 17 is disconnected, static electricity is not generated between the electrostatic column 17 and the umbrella-shaped cover 18, small impurities adsorbed on the surface of the electrostatic column can naturally fall down along with gravity and fall onto the bottom plate 11, mud can be formed after the small impurities are gradually accumulated on the surface of the bottom plate 11, the mud can move along the gradient of the bottom plate 11, finally the mud enters the spiral cover 13 from the mud inlet 12, the motor 15 drives the spiral rod 14 to rotate, and the spiral rod 14 conveys the mud from the bottom to the upper end of the spiral rod 14 when rotating and finally discharges the mud from the drain pipe 16.
The above is only a preferred embodiment of the present application; the scope of the application is not limited in this respect. Any person skilled in the art, within the technical scope of the present disclosure, may apply to the present application, and the technical solution and the improvement thereof are all covered by the protection scope of the present application.
