Description

Technical Field

[0001] The utility model relates to the technical field of oil production wastewater, and more specifically, to oil production wastewater treatment equipment. Background Art

[0002] Oil production wastewater is an important environmental problem generated by oil companies during the development process. This wastewater mainly comes from the oil field-specific wastewater formed during the crude oil extraction process when water and crude oil enter the crude oil gathering and transportation system together and undergo demulsification and dehydration.

[0003] Oil production wastewater not only carries crude oil, but also incorporates a large amount of salts in high-temperature and high-pressure strata, so it has a high degree of mineralization. In addition, the discharge of oil production wastewater will increase with the increase in oil production years, becoming the largest industrial wastewater produced in the oil field. In order to discharge the oil production wastewater harmlessly, treatment equipment is required to treat the oil production wastewater. Since the oil production wastewater also contains a large amount of solid impurities, these solid impurities will settle inside the equipment. After the oil production wastewater is discharged, the operator needs to clean up the impurities settled at the bottom of the equipment, which is very inconvenient, so it needs to be improved.

[0035] The inclined block 17 is fixedly mounted on the bottom of the inner surface of the filter plate 3 .

[0036] The cross-section of the rectangular block 5 is square, so that the lifting rod 7 will not rotate after being inserted into the threaded sleeve 6. The operator can rotate the fixing sleeve 9 to make the fixing sleeve 9 break away from the contact with the threaded sleeve 6, thereby releasing the fixing effect on the lifting rod 7. Due to the design of the filter plate 3, the filter plate 3 can filter solid impurities inside the oily wastewater.

[0040] The operator starts the first motor 13 to make the rotating shaft 14 drive the disc 15 to rotate, so that the round rod 16 can press and push the inner surface of the lifting frame 11, thereby making the lifting frame 11 move upward.

[0041] Among them, a water inlet pipe 19 is fixedly sleeved on the top of the left side of the box body 2, and a cover plate 18 is hinged on the top of the box body 2. The inner surface of the cover plate 18 is movably connected to the outer surface of the lifting rod 7.

The left end of the hinged rod 29 is movably sleeved on the outer surface of the connecting tube 25.

[0050] When the rotating rod 28 rotates, the hinge rod 29 will push the movable box 24 to move leftward through the connecting tube 25.

[0051] The working principle and use process of this utility model:

[0052] The operator can discharge the oil production wastewater into the interior of the box 2 through the water inlet pipe 19, and the solid impurities in the oil production wastewater will be deposited inside the filter plate 3, thereby preventing the impurities from clogging the drain pipe 20 and the oil drain pipe 21.

[0053] Since the oil separated from the oil production wastewater floats on the water, the operator can first discharge the wastewater through the drain pipe 20, and then discharge the waste oil through the oil drain pipe 21, thereby realizing oil-water separation. Then the operator can start the first motor 13 to make the rotating shaft 14 drive the disc 15 to rotate, so that the round rod 16 can squeeze and push the lifting frame 11 to move upward, so that the lifting frame 11 can drive the lifting rod 7 to rise under the limiting action of the limiting block 10, so that the lifting rod 7 can drive the filter plate 3 to rise, and then the lifting rod 7 drives the filter plate 3 to separate from the inside of the box body 2, and then by rotating the fixing sleeve 9, the fixing sleeve 9 is separated from the outer surface of the threaded sleeve 6, thereby releasing the fixation of the filter plate 3 as a whole, so that the filter plate 3 can be disassembled, which is convenient for the operator to clean the solid impurities inside the filter plate 3.
