[0026] The environmentally friendly restaurant sewage recycling machine provided in this embodiment provides a closed processing space and a structural setting basis by setting a casing 10, and introduces the sewage to be treated into the casing 10 by setting a liquid inlet channel 11; on this basis, a solid-liquid separation mechanism is set to separate the introduced sewage into solid and liquid, and an oil-water chamber 12 is set, and the discharge port of the solid-liquid separation mechanism is set directly above the oil-water chamber 12, so that the liquid separated by the solid-liquid separation mechanism is continuously accumulated in the oil-water chamber 12. Due to the different densities of oil and water, the two are naturally stratified in the oil-water chamber 12, and the oil layer is located above the water layer; on this basis, by setting An oil collecting chamber 13 is provided, and an oil-water separation mechanism is provided, which includes a power component and a plurality of oil pushing plates 20. The power component is used to drive the oil pushing plates 20 to periodically move above the oil-water chamber 12 to the edge above the oil collecting chamber 13, so that the oil pushing plates 20 are used to gradually push the oil layer located above the oil-water chamber 12 into the oil collecting chamber 13, thereby realizing effective oil-water separation. Through the mutual cooperation of the above-mentioned features, the catering sewage environmental protection recycling machine can effectively separate sewage into three parts: solid residue, oil and liquid, and wastewater, thereby realizing effective recovery of solid residue and oil, so that the solid residue and oil can be fully utilized separately in the subsequent process.
[0027] Preferably, in order to automatically control the oil-water separation, a liquid level sensor (not shown) is provided in the oil-water chamber 12 in the casing 10 for monitoring the liquid level in the oil-water chamber 12. When the liquid level reaches a preset level, the liquid level sensor transmits a signal to the control system of the oil-water separation mechanism to control its power component to start and implement oil-water separation.
[0028] It should be noted that the oil-water chamber 12 and the oil collecting chamber 13 are respectively provided with corresponding drain pipes and drain valves to facilitate the transfer of the liquid therein to the outside.
[0029] In order to further explain the specific structure of the power assembly, the power assembly includes at least one conveyor belt 21, which is horizontally arranged directly above the oil-water chamber 12, and all the oil pushing plates 20 are spaced apart on the outer surface of the conveyor belt 21; when the oil pushing plate 20 is located below the conveyor belt 21, the side of the oil pushing plate 20 away from the conveyor belt 21 is located in the oil-water chamber 12; when the oil pushing plate 20 is located above the conveyor belt 21, the oil pushing plate 20 is separated from the oil-water chamber 12.
[0030] Through the above-mentioned arrangement, on the one hand, the contact and separation of the oil-water mixture with the oil pushing plate 20 is implemented by utilizing the characteristic that the top and bottom surfaces of the horizontally arranged transmission belt 21 are arranged at different heights. Specifically, when the oil pushing plate 20 runs to the bottom surface of the conveyor belt 21, it contacts the oil-water mixture, and when the oil pushing plate 20 runs to the top surface of the conveyor belt 21, it separates from the oil-water mixture. On the second hand, by utilizing the unidirectional transmission of the bottom surface of the conveyor belt 21 and cooperating with the above-mentioned periodic contact and separation movement mode, periodic unidirectional oil pushing is realized, which effectively avoids the occurrence of reverse oil pushing and oil carrying. Moreover, during the oil pushing process, the oil pushing plate 20 always moves horizontally, and the oil pushing effect is stable.
[0031] Preferably, in order to optimize the oil pushing path, the starting end of the conveying direction of the bottom surface of the conveyor belt 21 is located at the end of the oil-water chamber 12 away from the oil collecting chamber 13; the terminal end of the conveying direction of the bottom surface of the conveyor belt 21 is located at the edge of the oil collecting chamber 13 on one side close to the oil-water chamber 12.
[0032] Preferably, in order to reduce the difficulty of pushing the oil from the oil-water chamber 12 into the oil collecting chamber 13, the oil-water chamber 12 and the oil collecting chamber 13 are separated by an isolation plate 14; the isolation plate 14 is a flat plate; the plane where the isolation plate 14 is located is perpendicular to the conveying direction of the conveyor belt 21.
[0033] Through the above arrangement, on the one hand, the thinner plate characteristic of the isolation plate 14 is utilized to reduce the span distance between the oil-water chamber 12 and the oil collecting chamber 13. On the other hand, the isolation plate 14 is set as a flat plate to effectively cooperate with the planar characteristics of the oil push plate 20 to further improve the oil separation efficiency.
[0034] Preferably, in order to further optimize the oil pushing direction and effectively prevent oil return or unnecessary turbulence, the plane where the oil pushing plate 20 is located is arranged parallel to the axial direction of the support roller of the conveyor belt; the oil pushing plate 20 is an elastic plate.
[0035] In order to further facilitate pushing the oil into the oil collecting chamber 13, the top side of the isolation plate 14 is connected to a ramp plate 15, and the side of the ramp plate 15 away from the isolation plate 14 is located in the oil-water chamber 12, and the setting height is lower than the setting height of the top side of the isolation plate 14; the oil pushing plate 20 can contact and squeeze the slope surface of the ramp plate 15.
[0036] The ramp plate 15 is provided to form a gentle slope at the isolation plate 14 , thereby further facilitating the oil to smoothly pass over the upper side of the isolation plate 14 .
[0037] Preferably, in order to further cooperate with the elastic oil push plate 20, the ramp plate 15 includes a rising plate 151 and a falling plate 152 connected at an obtuse angle to form a ridge 153 at the connection; the side of the falling plate 152 away from the rising plate 151 is connected to the top side of the isolation plate 14, and the setting height of the ridge 153 is higher than the setting height of the top side of the isolation plate 14.
[0038] Through the above arrangement, the convex ridge is used to form a turning slope, which further reduces the possibility of oil return.
[0039] In order to further explain the specific structure of the solid-liquid separation mechanism, the solid-liquid separation mechanism includes a collecting barrel 30, an auger 31 and a motor 32; the collecting barrel 30 is tiltedly arranged in the casing 10, and the lower part of the collecting barrel 30 is connected to the terminal of the feed flow channel 11, and the lower side wall of the lower part of the collecting barrel 30 is provided with a grid-shaped drain port 301, and the drain port 301 is located directly above the oil-water chamber 12; the upper part of the collecting barrel 30 is provided with a slag discharge port 302, and the slag discharge port 302 is located outside the casing 10; the auger 31 is coaxially arranged in the collecting barrel 30, and the motor 32 is arranged at the top of the collecting barrel 30, and is transmission-connected to the auger 31.
[0040] Through the above arrangement, the sludge flowing into the feed flow channel 11 is collected by the collecting cylinder 30, and the sludge is enriched in the lower part of the collecting cylinder 30. The rotation of the auger 31 will drive the solid residue in the sludge to move upward with the auger until it is discharged from the residue discharge port 302, while the liquid in the sludge will not move upward with the auger, thereby achieving effective solid-liquid separation. The liquid in the sludge automatically flows into the oil-water chamber 12 through the liquid discharge port 301 under the action of its own gravity, preparing for subsequent oil-water separation.
[0041] In order to further facilitate pouring the sewage into the feed channel 11 , a feed funnel 16 is provided on the top of the housing 10 , and the outlet end of the feed funnel 16 is connected to the starting end of the feed channel 11 .
[0042] In order to pre-treat the solid residue with too large particle size and the solid matter with long length in the sewage, a filter screen 17 is provided at the outlet end of the feed funnel 16; a cutting disc 18 is provided parallel to the top surface of the filter screen 17, and the cutting disc 18 is connected to a driving mechanism.
[0043] Through the above arrangement, the filter screen 17 is used to filter and support the above substances, and then the driving mechanism is used to drive the cutting disc 18 to rotate and cut the above substances until their particle size is smaller than the aperture of the filter screen 17, and then they can pass through the filter screen 17 and enter the solid-liquid separation mechanism.
[0044] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
