Description

Technical Field

[0001] The invention relates to the technical field of oil-water separation kitchenware, and in particular to an oil-water separation device for continuous oil removal. Background Art

[0002] Nowadays, the amount of domestic sewage is increasing, especially the sewage from restaurants contains a lot of edible oil. The state has mandatory regulations that the oily sewage from restaurants must be treated with oil-water separation before it can be discharged. However, the existing equipment only performs initial separation of oily sewage, and a layer of oil film still floats in the discharged sewage, which does not fundamentally solve the sewage problem. At present, there are few devices for oil film separation, and the manufacturing and use costs of these devices are high, so they are restricted by market prices.

[0003] Patent No. CN201610843964.1 discloses an oil-water separation device for separating and recovering edible oil, including a shell, a feed port arranged on one side of the upper part of the shell, and multiple flow-blocking columns are evenly distributed below the feed port in the shell. The multiple flow-blocking columns form a comb column array, and a wave-shaped wave-breaking plate is arranged between the comb column array and the water outlet. An overflow port is arranged on the upper part of the wave-breaking plate, and an inclined plate is arranged below the overflow port on the side of the wave-breaking plate facing the water outlet. An oil suction device with a hydrophobic oil-absorbing sponge is arranged above the inclined plate, and the end of the inclined plate is connected to the water outlet. The oil suction device is used to absorb the oil on the inclined plate. The oil-water separation device of the invention can better promote the stratification of oil and water and separate oil and water. After being absorbed by the oil suction device, the concentration of the separated oil is very high, and the content of water impurities is very small, which greatly reduces the post-processing of the recovered oil, and can realize continuous oil-water separation. The oil-water separation efficiency is high, and the manufacturing and use costs are relatively low, which is conducive to market application.

[0004] The above-mentioned existing oil-water separation and recovery device for kitchen utensils has the following drawbacks: the oil-water separation and recovery device for kitchen utensils of the application absorbs grease through an oil-absorbing sponge during oil-water separation. This method can only recover water but not grease, which easily leads to waste of resources. At the same time, a small amount of water will also be absorbed when absorbing grease, and the water and grease cannot be effectively separated, resulting in low purity of water and grease, which is not conducive to use after recovery. Therefore, it is necessary to develop an oil-water separation device for continuous oil removal. Summary of the invention

It can filter the oil and water continuously for a long time and can separate the oil and water into pure water and debris oil, thereby reducing the discharge of dirty oil and increasing the amount of pure water available. Specifically, it has the following beneficial effects:

[0038] 1. The invention separates the debris oil and water by high-speed rotation of the filter cartridge 3 and the centrifugal force of oil and water. The invention has a compact structure, a small volume, and a large filtering capacity. It can separate the oil and water into pure water and debris oil, thereby reducing the discharge of dirty oil and increasing the use of pure water.

[0039] 2. The present invention presses the filter screen 1 onto the side wall of the filter cartridge 3 by means of the pressing frame 2, so that the filter screen 1 can be disassembled and replaced, thereby extending the life of the equipment;

[0040] 3. The present invention provides a lower bearing groove 18 in the water bucket 5 for placing the lower bearing 9, and provides an upper bearing groove 19 in the water bucket cover 10 for placing the upper bearing 8, so that the resistance of the filter cartridge 3 to rotation is small, which is conducive to high-speed rotation filtering of oil and water;

[0041] 4. The present invention provides a sealing connector 7, which is provided with an oil-water inlet 13 for injecting oil-water into the filter space and a debris oil outlet 14 for discharging the remaining filtered matter from the filter space. The sealing connector 7 changes the debris oil outlet and the oil-water inlet on the filter cartridge 3 from a rotating state to a stationary state, so that an external water pipe can be connected, and the water pipe cannot rotate;

[0042] 5. The present invention increases the strength of the filter cartridge 3 by arranging a connecting plate 21 between the oil-water pipe 20 and the side wall of the filter cartridge 3. The connecting plate 21 can promote the oil-water to rotate highly so as to enhance the filtering effect. This can prevent the filter cartridge 3 from deforming under high-speed rotation, which in turn affects the rotation of the filter cartridge 3 and further affects the filtering function.

[0043] 6. The present invention is provided with an oil-water inlet 13 through a sealing connector 7 so that oil-water can be injected into the filter space and a debris oil outlet 14 so that the remaining filtered matter can be discharged from the filter space. The debris oil outlet and the oil-water inlet on the filter cartridge 3 are arranged above the filter cartridge 3, and a filtered pure water outlet 12 is arranged below the water bucket 5. Based on the principle that oil is lighter than water, the debris oil will float above the oil-water. When the filter cartridge 3 is filled, the debris oil will automatically overflow from the debris oil outlet 14;

[0044] 7. The present invention provides a guide plate 22 at the lower end of the side wall of the filter cartridge 3 so that the water passing through the filter screen flows down along the guide plate 22, thereby preventing the water passing through the filter screen from flowing down the rotating shaft 17 and then entering the motor 6, thereby preventing the motor 6 from leaking electricity due to water.

[0045] The embodiments described above are only preferred implementation modes of the present invention and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and modifications made by those skilled in the art on the basis of the invention shall fall within the protection scope of the present invention.
