Description

Technical Field

[0001] This application relates to the field of oil-water separators, and particularly to an oil-water separator without an oil scraping device. Background Art

[0002] The waste oil contained in food waste, if not recycled resourcefully, will be directly discharged with the wastewater generated by the catering industry, causing blockages in the urban sewage drainage network, often requiring manual cleaning, or being purchased by illegal manufacturers and used to produce gutter oil and return to the dining table.

[0003] In actual use of the existing integrated oil-water separator, due to the long-term use of the preliminary filtration structure, it will become blocked. This is mainly because the viscosity of the food waste water is relatively high, resulting in a large amount of impurities adhering to the filtration structure and causing it to become blocked. Utility Model Content

[0010] With the above structure, the filter screen on the filter sleeve facilitates the filtration of wastewater, preventing impurities in the wastewater from entering the collection box. When the filter sleeve rotates, it cooperates with the scraper to conveniently clean the impurities adhering to the filter screen.

[0011] One inner wall of the transfer box is rotatably connected with a drive pipe, and one end of the drive pipe is fixedly connected to the filter sleeve. The filter sleeve and the drive pipe are in communication, and a plurality of arc-shaped openings are equidistantly distributed on the outer wall of the drive pipe.

[0031] The filtering mechanism 2 for filtering wastewater includes a filtering tank 8 fixedly connected to the collection tank 1, and a filtering assembly 16 is provided on the inner wall of the bottom of the filtering tank 8. One outer wall of the filtering tank 8 is fixedly connected to a connecting pipe 13, and one end of the connecting pipe 13 is connected to the collection tank 1 through a pipeline;

[0032] During use, impurities in the wastewater are filtered by the filtering component 16 in the filtering tank 8 to prevent the impurities in the wastewater from entering the collection tank 1;

[0033] The filtering component 16 for filtering wastewater includes a transfer tank 17 fixedly connected to the inner upper part of the bottom of the filtering tank 8, and the transfer tank 17 is communicated with the connecting pipe 13. A circular opening II is formed in the outer wall of one side of the transfer tank 17, and a filtering sleeve 18 is rotatably connected to the inner wall of the circular opening II. A plurality of equally spaced openings are formed in the outer wall of the filtering sleeve 18, and a filter net 19 is fixedly connected to the inner wall of the opening. A scraper 20 is fixedly connected to the outer wall of one side of the transfer tank 17, and the scraper 20 is in contact with the filter net 19. A driving pipe 21 is rotatably connected to the inner wall of one side of the transfer tank 17, and one end of the driving pipe 21 is fixedly connected to the filtering sleeve 18. The filtering sleeve 18 is communicated with the driving pipe 21, and a plurality of equally spaced arc-shaped openings 22 are formed in the outer wall of the driving pipe 21;

[0034] During use, the filter net 19 in the filtering sleeve 18 facilitates the filtration of wastewater. When the filtering sleeve 18 rotates, it cooperates with the scraper 20 to facilitate the cleaning of impurities adhered to the filter net 19. The setting of the driving pipe 21 facilitates the introduction of the wastewater filtered by the filtering sleeve 18 into the transfer tank 17, and the setting of the plurality of arc-shaped openings 22 facilitates the direct discharge of the wastewater into the transfer tank 17;

[0035] The driving component for driving the rotation of the filtering sleeve 18 in the filtering component 16 includes a pulley I rotatably connected to the outer wall of the filtering tank 8, and one end of the transmission shaft of the pulley I is fixedly connected to the driving pipe 21. A servo motor 14 is fixedly connected to the outer wall of the filtering tank 8, and a pulley II is fixedly connected to the output shaft of the servo motor 14. The pulley II and the pulley I are connected by the same belt 15;

[0036] During use, the servo motor 14 cooperates with the belt 15 to directly drive the driving pipe 21 to rotate, thereby driving the filtering sleeve 18 to rotate. When the filtering sleeve 18 rotates, the impurities adhered to the filter net 19 are directly cleaned by the scraper 20;

[0037] The automatic slag discharging component installed on the collection tank 1 includes a slag discharging pump 4. The setting of the slag discharging pump 4 facilitates the direct transportation of the residues in the filtering tank 8 to the slag collection bucket 6 through the slag discharging pipe 5. An inlet pipe 3 for the wastewater to enter the filtering mechanism 2 is provided on the filtering tank 8.

[0038] The oil discharging component 9 installed on the collection tank 1 facilitates the direct transportation of the upper-layer oil liquid in the collection tank 1 to the oil collection bucket 12 through the oil discharging tank 10 and the oil discharging pipe 11.

[0039] The implementation principle of an oil-water separator without an oil scraping device in an embodiment of this application is as follows: When in use, wastewater enters the filtration tank 8 through the water inlet pipe 3, and then the wastewater is filtered by the filter net 19 on the filter sleeve 18. The filtered wastewater enters the transfer tank 17, and then flows into the collection tank 1 through the connecting pipe 13. After the wastewater stays still in the collection tank 1 for a period of time, the oil liquid is directly discharged through the oil discharge assembly 9, and the water is directly discharged through the drain pipe 7. After the filtration mechanism 2 filters for a period of time, the filter net 19 on the filter sleeve 18 needs to be cleaned. When cleaning, the servo motor 14 is started to drive the driving pipe 21 through the belt 15 to drive the filter sleeve 18 to rotate. When the filter sleeve 18 rotates, the scraper 20 directly cleans the impurities adhered to the filter net 19, and finally the slag discharge pump 4 is started to directly discharge the filtered residue.

[0040] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
