Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a wastewater treatment device for petroleum additive production. Background Art

[0002] Petroleum additive wastewater refers to the wastewater generated by some chemical additives (additives) used in the process of oil extraction, processing and use. They can improve oil recovery efficiency, improve oil product performance or promote the oil refining process. However, these additives and their reaction products often have certain toxicity and environmental hazards. Petroleum additive wastewater solid-liquid separation can effectively separate the solid particles and liquid in the wastewater, so as to facilitate further treatment and recycling.

[0003] Using filtering devices (such as filter screens, etc.) to intercept solid particles in wastewater is a commonly used method for solid-liquid separation of petroleum additive wastewater. However, the solid particles intercepted on the filter screen are not easy to collect and need to be manually cleaned to clean and collect the solid particles. When cleaning the solid particles, the solid-liquid separation of the wastewater will be interrupted. Therefore, it is not only time-consuming and labor-intensive, but also affects the solid-liquid separation efficiency of the wastewater. Summary of the invention

The baffle 14 is a circular plate body, and the right end of the arc plate 3 slides and contacts the baffle 14. The inner wall of the net cylinder 4 is arrayed with filter plates 7, and the inner end of each filter plate 7 faces the central axis of the shell 1. The outer end of the filter plate 7 is connected to one end of the net cylinder 4, and the other end is the inner end. The diameter of the circle where the inner ends of the plurality of filter plates 7 are located corresponds to the diameter of the circle where the outer wall of the arc plate 3 is located; the shell 1 is provided with a driving member for driving the net cylinder 4 to rotate; the lower part of the left side plate of the shell 1 is connected to a liquid inlet pipe 8 opposite to the lower part of the left end opening of the net cylinder 4, and the lower end of the peripheral wall of the shell 1 is connected to a liquid outlet pipe 9.

[0023] The filter plate 7 is a rectangular plate body with filter holes 13 evenly distributed thereon, and the length of the filter plate 7 is equal to the length of the mesh tube 4 .

[0024] The central angle of the arc plate 3 is 240°, and the number of the filter plates 7 is 6.

[0025] The guide plate 6 is a rectangular plate body, and the front and rear ends of the guide plate 6 are respectively fixedly connected to the front and rear parts of the inner wall of the arc plate 3 , and the length of the guide plate 6 is equal to the length of the arc plate 3 .

[0026] A viewing window 15 is provided at the front of the peripheral wall of the shell; the outer diameter of the net cylinder 4 is smaller than the inner diameter of the shell 1 , and the outer annular surface of the baffle 14 is in sliding contact with the inner wall of the shell 1 .

[0027] The driving member includes a connecting ring 10, a connecting rod 11 and a motor 12. The left end of the outer wall of the net cylinder 4 is fixed with a connecting ring 10, and the connecting ring 10 is a circular ring plate. The outer ring surface of the connecting ring 10 slides in contact with the inner wall of the shell 1, and the opposite sides of the connecting ring 10 and the baffle 14 slide in contact with the left and right inner surfaces of the shell 1 respectively. The connecting ring 10 and the baffle 14 are connected via a plurality of connecting rods 11, and the connecting rods 11 are round rods. The motor 12 is fixed on the outer right side of the shell 1, and the output end of the motor 12 passes through the right side plate of the shell 1 and connects to the middle part of the baffle 14.

[0028] When in use, the petroleum additive wastewater with solid particles is discharged into the lower part of the net cylinder 4 through the liquid inlet pipe 8. The solid particles in the wastewater entering the net cylinder 4 are intercepted by the lower part of the net cylinder 4. The wastewater with solid particles separated enters the lower part of the shell 1 through the lower part of the net cylinder and is discharged from the liquid outlet pipe 9. The flow rate of the liquid inlet pipe is controlled and observed through the window 15 so that the height of the wastewater retained in the shell is not higher than the lower end of the arc plate; at the same time, the motor 12 drives the baffle 14 to rotate counterclockwise (the counterclockwise rotation of the baffle 14 is Figure 3 The baffle 14 drives the connecting ring 10 to rotate synchronously through the connecting rod 11, and the baffle 14 and the connecting ring 10 jointly drive the net cylinder 4 to rotate counterclockwise. When the net cylinder 4 rotates, the multiple filter plates 7 rotate with the net cylinder 4. When the filter plate 7 on the lower side of the arc plate rotates, the solid particles trapped in the lower part of the net cylinder 4 can be driven to rotate with the net cylinder 4. Since the diameter of the circle where the inner ends of the multiple filter plates 7 are located matches the diameter of the circle where the outer wall of the arc plate 3 is located, the inner end of the filter plate 7 located at the lower part of the arc plate 3 slides in contact with the outer wall of the filter plate 7, which can Ensure that the filter plate 7 at the bottom of the arc plate 3 drives the solid particles to rotate with the net cylinder 4, and the solid particles will not be retained at the bottom of the net cylinder 4. As the net cylinder 4 rotates, the filter holes 13 on the filter plate 7 can allow water to pass through, but can intercept solid particles. When the filter plate 7 moves to the upper side of the arc plate 3, the filter plate 7 is in a state where the inner end is low and the outer end is high. Under the action of the dead weight of the solid particles, they can roll into the arc plate 3 along the inclined direction of the filter plate 7. Under the guidance of the guide plate 6 with the lower left and higher right, the solid particles can be discharged from the housing 1 through the circular hole 5;

[0029] Therefore, during the rotation of the mesh drum 4 of the utility model, the solid particles trapped by the mesh drum 4 and the filter plate 7 can be discharged from the housing 1 , and the wastewater from which the solid particles are separated can be discharged through the liquid outlet pipe 9 .
