Description

Technical Field

[0001] This utility model relates to the field of kitchen waste treatment technology, specifically to a kitchen waste oil-water separation device. Background Technology

[0002] The kitchen waste oil-water separator is a device used to separate grease, water and solid waste from catering wastewater. It is widely used in restaurants, canteens, hotels and other places.

[0003] First, without filtering for both coarse and fine impurities, solid residues in the wastewater will directly enter the oil-water separator. This will not only affect the efficiency of oil-water separation but may also cause filter clogging, increasing the difficulty of equipment cleaning and maintenance.

[0004] Secondly, if the step plate cannot be removed, cleaning becomes very cumbersome, and impurities easily accumulate on the fixed plate surface, making it impossible to remove them completely. This can lead to a decrease in equipment efficiency and may even cause incomplete oil-water separation.

[0005] Finally, if the oil-water separation is not rapid enough, the oil and water will form an emulsion or mix deeply, resulting in poor separation and water quality that fails to meet standards. The discharged water may contain a lot of oil. Summary of the Invention

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] Please see Figures 1-6 A kitchen waste oil-water separation device includes a main body 1, a pretreatment component, an installation mechanism, and an operating mechanism. The pretreatment component includes a closing cover 2, a filter frame 3, and a stepped plate 4. The closing cover 2 is mounted on the main body 1 and rotatably connected to the main body 1. The filter frame 3 is mounted on the main body 1 and cooperates with the main body 1. The stepped plate 4 is installed inside the main body 1 and cooperates with the main body 1. The installation mechanism includes a first spring 5, a fixing frame 6, a rotating component 7, a second spring 8, and a driving component 9. The first spring 5 is fixedly mounted on the stepped plate 4, and its other end is fixedly connected to the fixing frame 6. The fixing frame 6 is installed inside the stepped plate 4 and slidably connected to the stepped plate 4. The rotating component 7 is installed inside the stepped plate 4 and rotatably connected to the stepped plate 4. The second spring 8 is fixedly mounted in the rotating component 7, and its other end is fixedly connected to the driving component 9. The driving component 9 is installed in the rotating component 7 and slidably connected to the rotating component 7.

[0032] In this embodiment, the pretreatment component includes a closed cover 2, a filter frame 3, and a stepped plate 4. In use, the filter frame 3 needs to be installed on the main body 1 first to perform initial filtration of the wastewater. After filtration, the filter frame 3 needs to be removed and large debris in the filter frame 3 needs to be emptied. In this process, the closed cover 2 is opened first, and then the filter frame 3 is picked up. At this time, the fitting block 18 on the filter frame 3 slides in the fitting groove 17 of the main body 1, and the wastewater flows directly onto the stepped plate 4 after being filtered by the filter frame 3. The small debris contained therein is blocked by the stepped plate 4.

[0033] In this embodiment, the installation mechanism includes a first spring 5, a fixing frame 6, a rotating component 7, a second spring 8, and a driving component 9. In use, the step plate 4 can be installed onto the main body 1. During installation, the insertion slot 24 on the step plate 4 and the limiting plate 23 on the main body 1 are connected. When the first sealing gasket 20 on the step plate 4 contacts the main body 1, the driving component 9 can be pulled first, so that the driving component 9 can slide in the rotating component 7 and compress the second spring 8. The positioning rod 27 on the driving component 9 also disengages from the positioning hole 26 on the step plate 4. Then, the driving component 9 is rotated, so that the rotating component 7 can rotate inside the step plate 4. During this process, the connecting rope 21 installed in the mounting slot of the rotating component 7 is unwound on the rotating component 7. The fixing frame 6 is pushed by the compressed first spring 5, thereby pushing the fixing frame 6 to connect with the locking hole 19 to complete the fixing of the step plate 4.

[0034] In this embodiment, the operating mechanism includes an oil suction plate 10, an oil suction pump 11, a drainage component 12, a baffle 13, and a control assembly. During use, since the wastewater on the stepped plate 4 inside the main body 1 fills the main body 1, while the oil layer floats on the surface, the oil suction pump 11 can be controlled to operate, causing the oil suction plate 10, which is in contact with the oil layer, to absorb the oil, thus completing the separation of oil and water. After the oil layer has been absorbed, the baffle 13 can be opened appropriately, allowing the second sealing gasket 25 on the baffle 13 to detach from the stepped plate 4, creating a gap that allows water to flow out. During this process, the electric push rod 16 drives the lifting frame 14 directly onto the main body 1, and the connecting rod 15, which is rotatably connected to the lifting frame 14, also pulls the baffle 13 at the same time, thus controlling the baffle 13. When water flows out of the gap, it eventually enters the drainage component 12 and then collects and discharges to the outside of the main body 1. However, the water flow on the stepped plate 4 controls the outflow, so that when the wastewater enters again, the oil layer will still come into contact with the oil absorption plate 10. With the cooperation of the baffle 13 and the stepped plate 4, the water flow will not affect the stability of the oil layer.

[0035] Example 2:

[0036] In summary, during use, the filter frame 3 must first be installed onto the main body 1 for initial filtration of the wastewater. After filtration, the filter frame 3 must be removed, and large debris inside must be emptied. During this process, the closing cover 2 is opened first, and then the filter frame 3 is lifted. At this time, the fitting block 18 on the filter frame 3 slides in the fitting groove 17 of the main body 1, and the wastewater flows directly onto the stepped plate 4 after being filtered by the filter frame 3. Small debris contained within is blocked by the stepped plate 4, which requires frequent cleaning. At this point, the step plate 4 can be installed onto the main body 1. During installation, the insertion slot 24 on the step plate 4 and the limiting plate 23 on the main body 1 are connected. After the first sealing gasket 20 on the step plate 4 contacts the main body 1, the driving component 9 can be pulled first, allowing it to slide within the rotating component 7 and compress the second spring 8. The positioning rod 27 on the driving component 9 also disengages from the positioning hole 26 on the step plate 4. Then, the driving component 9 is rotated, allowing the rotating component 7 to rotate inside the step plate 4. During this process, the connecting rope 21 installed in the mounting slot of the rotating component 7... The rotating part 7 is unwound, while the fixed frame 6 is compressed by the first spring 5, which pushes the fixed frame 6 to engage with the locking hole 19, thus fixing the stepped plate 4. After wastewater enters the main body 1, the wastewater on the stepped plate 4 inside the main body 1 fills the main body 1, while the oil layer floats on the surface. The oil suction pump 11 can be controlled to work, so that the oil suction plate 10 in contact with the oil layer absorbs the oil layer, completing the separation between oil and water. When the oil layer is completely absorbed, the baffle 13 can be opened appropriately, allowing the second sealing gasket 25 on the baffle 13 to detach from the stepped plate 4, preventing leakage. The gap allows water to flow out. During this process, the electric push rod 16 drives the lifting frame 14 to pull the main body 1, and the connecting rod 15, which is rotatably connected to the lifting frame 14, also pulls the baffle 13 at the same time, thus controlling the baffle 13. When the water flows out of the gap, it eventually enters the drainage component 12 and then collects and is discharged to the outside of the main body 1. However, the water flow on the stepped plate 4 is controlled to ensure that the oil layer still contacts the oil absorption plate 10 after the next wastewater enters. With the cooperation of the baffle 13 and the stepped plate 4, the water flow does not affect the stability of the oil layer.
