Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an environmentally friendly and efficient oily wastewater treatment device. Background Art

[0002] Oily wastewater refers to wastewater containing grease, oil, fat, petroleum compounds or other organic matter. This wastewater usually comes from industrial production, processing, cleaning, cooling or sewage treatment processes, such as factory production wastewater, cooling water for mechanical equipment, kitchen wastewater in the catering industry, etc.

[0003] Oily wastewater treatment devices are equipment systems used to treat wastewater containing grease, oil, fat, petroleum compounds or other organic matter. These devices are usually composed of multiple units to remove pollutants from wastewater to meet environmental discharge standards or reusable water quality. In existing oily wastewater treatment devices, the stirring mechanism helps to promote the mixing of flocculants with pollutants in wastewater to form larger flocs so that they can be separated more easily. However, most of the existing stirring mechanisms are single stirring, which cannot quickly and effectively improve and speed up the mixing speed, resulting in poor flocculation effect, making the subsequent sedimentation or filtration process less efficient, and the pollutants in the wastewater are unevenly distributed, affecting the treatment effect. In addition, when the treatment device is used for a long time, the filter device inside the treatment device may greatly reduce the filtration effect. When replacing and cleaning the filter device, it may take more time and manpower, and increase the complexity of maintenance, resulting in delayed maintenance process to avoid downtime caused by disassembly and reinstallation. This may cause the filter performance to decline and affect the wastewater treatment efficiency. Utility Model Content

The buckle 607 on the top of the base 606 is placed in the interior of the shell 601. After loosening the sliding rod 602, the other end of the sliding rod 602 can be inserted into the internal hole groove of the buckle 607 for fixing and supporting. The four buckles 607 are set corresponding to the two shells 601 and the sliding rod 602.

The filter plate 11 is used to achieve a preliminary filtering effect, so that larger sediments and impurities in the wastewater are filtered out and fall into the interior of the connection box 10. Guide rails 13 are fixedly connected to the left and right sides of the interior of the filter box 7. The two guide rails 13 are slidably connected to the slot box 14. The slot box 14 can be easily taken out for replacement through the set guide rails 13. In addition, when fillers such as fiber filter balls are placed in the interior of the slot box 14, they can be easily processed in a unified manner, and the wastewater can be easily filtered delicately to improve the filtering effect. The front side wall of the slot box 14 is fixedly connected to a connecting block 15, and the front side wall of the connecting block 15 is fixedly connected to a handle 16.

[0036] It should be noted that the utility model is an environmentally friendly and efficient oily wastewater treatment device. First, the motor 201 is connected to an external power source, and then connected to an external pipeline through a feed pipe 3 to transfer the wastewater to the barrel body 1, and then the medicine is put into the barrel through the medicine inlet pipe 20.

[0037] The stirring blade 209 is driven to rotate by the bottom end of the rotating rod 202 on the output end of the motor 201 to stir the suspended matter and sediment in the wastewater, maintain the uniformity of the wastewater, and increase the mixing speed. The first gear 203 rotating at the top of the rotating rod 202 drives the second gear 204 to rotate inside the gear plate 205, and drives the connecting rod 207 inside the second gear 204 to rotate. When rotating, it drives the stirring rod 210 on the outside of the connecting rod 207 to stir and mix the wastewater and the medicine, and fully mix them with the medicine to ensure that the wastewater and the medicine in the wastewater are evenly distributed and in full contact.

[0038] After stirring, the wastewater will be transferred to the filter box 7 through the discharge pipe 4 and the first delivery pipe 12 for filtering. When filtering, it will first be filtered through the filter plate 11 to filter out the larger sediments and impurities in the wastewater, and then fall into the connection box 10 for collection. When the connection box 10 needs to be replaced and cleaned, the sliding rod 602 is pressed to slide inside the shell 601. The sliding rod 602 will squeeze the first spring 603 when sliding, and the first spring 603 will be used to achieve the effect of rebound and reset. The sliding rod 602 squeezes the first spring 603. After the first spring 603 is released, the buckle 607 is placed inside the shell 601. After the sliding rod 602 is released, the sliding rod 602 will enter the internal hole groove of the buckle 607 to fix the fixing ring 8 and the connecting ring 9. However, after the buckle 607 is placed inside the shell 601, the top of the buckle 607 will press against the connecting plate 605 to squeeze the second spring 604. When the device is unlocked, the second spring 604 will drive the connecting plate 605 to rebound and reset, and close the hole groove of the shell 601 to prevent external impurities from entering the interior, thereby effectively reducing maintenance time.

[0039] By placing fillers such as fiber filter balls in the slot box 14, the wastewater can be filtered delicately to improve the filtering effect.

[0040] When the slot box 14 needs to be replaced, the connection block 15 on the rear side of the handle 16 needs to be fixed to the front side wall of the slot box 14 to facilitate taking out the slot box 14 for replacement and processing.
