[0002] The wastewater purification device used for environmental protection of oil and gas field projects is usually oilfield wastewater treatment equipment. Its main purpose is to remove harmful substances in the oily wastewater generated during the oilfield production process and ensure that the water quality meets environmental protection emission standards.

By setting a filter inclined plate in conjunction with a decontamination tank and a decontamination pipe, it is convenient to treat the dirt separated from the sewage, so that the dirt can be treated centrally, reducing the working cost. With the pull-out handle, the filter inclined plate can be pulled out of the sewage purification box to facilitate cleaning of its surface, further saving the sewage treatment cost of the device and making it more environmentally friendly. By setting an electric heating block in conjunction with a partition, the electric heating block can perform preliminary sterilization on the filtered sewage through the partition, thereby enhancing the sterilization effect and effectively improving the working efficiency of the device.

[0025] A spring 3 is provided between the collection box 715 and the rotating door 716 , and the spring piece 718 contacts the collection box 715 , and the rotating door 716 is driven to reset by the spring 3 .

[0026] A shovel plate 801 is slidably installed on the bottom of the inner wall of the sewage treatment tank 1, and a T-shaped rod 802 is fixedly installed on the top of the shovel plate 801. The inner wall of the sewage treatment tank 1 is provided with a circular groove, and the T-shaped rod 802 slides on the inner wall of the circular groove. A limit block 803 is fixedly installed on the bottom of the inner wall of the sewage treatment tank 1. A U-shaped water outlet pipe 9 is fixedly passed through the surface of the partition three 503. A water outlet hole is provided at the bottom of the sewage treatment tank 1, which can absorb and discharge the fine particles inside the long groove, thereby avoiding the accumulation of a large amount of fine particle sediment at the bottom of the third layer after long-term oily sewage treatment, thereby improving work efficiency.

[0028] When the present embodiment is working, the sewage and the medicine are fully mixed and diluted and then discharged to the third layer through the filter plate 710. After the sewage is discharged to the third layer, the sewage is added again for treatment, and the motor 10 is started. The motor 10 drives the long rod 401 to rotate, and the rotation of the long rod 401 drives the stirring blade 402 to rotate, and the rotation of the stirring blade 402 drives the rotating block 702 to rotate, and the rotation of the rotating block 702 drives the pressing plate 704 to rotate, and the rotation of the pressing plate 704 drives the pressing door 705 to press down, and the pressing door 705 presses down and drives the sliding rod 709 to move, and the sliding rod 709 moves and drives the small gear 708 to rotate, and the small gear 708 rotates and drives the winding wheel 707 to rotate, and the winding wheel 707 rotates and drives the rope to pay out the line. At this time, the filter plate 710 rotates due to the rope paying out. The filter plate 710 rotates, driving the threaded column 712 to contact the inner wall of the third layer and rotate. The threaded column 712 rotates and drives the scraper rod 714 to rotate. At this time, the filter plate 710 processes the impurities on its surface while rotating, so that the filter plate 710 can process the impurities on its surface each time the filtering is completed, which can improve the filtering effect of the filter plate 710 and improve work efficiency. The filter plate 710 rotates and drives the curved rod 717 to rotate. The curved rod 717 rotates and contacts the collection box 715, which can achieve contact and vibration of the filter plate 710. While scraping the surface impurities, the surface impurities are vibrated so that they can easily fall into the inbox, thereby improving the effect of collecting impurities on its surface and improving work efficiency.

[0029] After the sewage is discharged, there will be sediment at the bottom of the third layer due to the residue. The rotation of the filter plate 710 drives the shovel plate 801 to move, so that the sediment is pushed into the long groove opened at the bottom by the inclined surface of the shovel plate 801. After the water level reaches a certain height, the sewage will be discharged through the U-shaped outlet pipe 9, which can absorb and discharge the fine particles inside the long groove, avoiding the accumulation of a large amount of fine particle sediment at the bottom of the third layer after long-term oily sewage treatment, thereby improving work efficiency. After the shovel plate 801 moves to the direction of the U-shaped outlet pipe 9, the limit block 803 curved surface lifts it up and down, and the T-shaped rod 802 slides into the circular groove. When the filter plate 710 is reset, the T-shaped rod 802 is reset in the circular groove through the T-shaped rod 802 because a spring is provided between it and the inner wall of the third layer, ensuring that the shovel plate 801 will not bring its impurities into the direction away from the long groove when it is reset. There is no need for manual processing of sedimentation, which improves work efficiency.
