Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 5, an oil separation and lifting integrated device comprises a deslagging and separating mechanism 3 for separating solid waste from restaurant wastewater, wherein the deslagging and separating mechanism 3 comprises a deslagging box 19 and an auger deslagging device 4, the auger deslagging device 4 comprises a deslagging cylinder 22 extending into the deslagging box 19, a plurality of first deslagging holes are formed in the deslagging cylinder 22, and a conveying auger 5 is arranged in the deslagging cylinder 22.

When the restaurant wastewater is treated, the restaurant wastewater is firstly sent into the deslagging box 19, after entering the deslagging box 19, large-particle solid waste in the restaurant wastewater enters the deslagging barrel 22 through a first deslagging hole on the deslagging barrel 22, then the solid waste is conveyed to the outside of the deslagging box 19 by the conveying auger 5, and the wastewater is temporarily stored in the deslagging box 19 for subsequent treatment. When the conveying auger 5 breaks down or damages and needs to be maintained, the connecting plate 33 is separated from the deslagging box 19, then the auger slag remover 4 is taken down through the notch 32, maintenance can be performed, after maintenance is completed, the deslagging cylinder 22 is conveyed into the deslagging box 19 through the notch 32 again, the connecting plate 33 is connected with the deslagging box 19 again, and the detachably arranged auger slag remover 4 is convenient to overhaul and maintain, so that the use cost can be reduced.

In order to guarantee that the connecting plate 33 can accurately seal the notch 32, the occurrence of gaps to cause the leakage of restaurant wastewater is avoided, the notch 32 is communicated with the top of the deslagging box 19, and the connecting plate 33 is fixedly connected with the positioning plate 34, when the connecting plate 33 is attached to the deslagging box 19, the positioning plate 34 is attached to the top of the deslagging box 19, so that the connecting plate 33 is positioned by the positioning plate 34, and the occurrence of gaps caused by dislocation of the connecting plate 33 is avoided. On this basis, the connection plate 33 is connected to the deslagging box 19 by a plurality of bolts, and a sealing ring is fixedly arranged on the inner side of the connection plate 33.

In order to fully separate large-particle solid waste in restaurant wastewater, adverse effects on subsequent processing flows are avoided, the auger slag remover 4 further comprises a slag removing hopper 20 arranged in a slag removing box 19, a slag removing cylinder 22 penetrates into the slag removing hopper 20 and is fixedly connected with the slag removing hopper 20, a plurality of second slag removing holes are formed in the slag removing hopper 20, and the aperture of each second slag removing hole is smaller than that of each first slag removing hole. The restaurant wastewater entering the deslagging box 19 enters the deslagging hopper 20, and because the aperture of the second deslagging hole is smaller, the large-particle solid waste can not directly fall off through the second deslagging hole, but can be stored in the deslagging hopper 20, further enter the deslagging barrel 22 through the first deslagging hole and then be conveyed away by the conveying auger 5, and meanwhile, the wastewater can smoothly pass through the second deslagging hole to temporarily exist in the deslagging box 19.

Although the large-sized solid waste can be transported to the outside by the transporting auger 5, the restaurant wastewater still includes some small-sized solid waste, which passes through the second deslagging hole and is deposited in the deslagging box 19 to form sludge, in order to prevent the sludge from escaping from the deslagging box 19 and interfering with the subsequent treatment process, the deslagging box 19 is communicated with the water inlet pipe 35 and the water outlet pipe 36, the water inlet pipe 35 is positioned above the water outlet pipe 36, the filter grid 21 is detachably arranged on the inner wall of the deslagging box 19, and the filter grid 21 is arranged at the inlet of the water outlet pipe 36. The filter grid plate 21 is arranged at the inlet of the water outlet pipe 36, so that small-particle solid waste can be filtered, namely, sludge is filtered, and the sludge is prevented from being separated from the deslagging box 19. After a period of use, the deposited sludge needs to be cleaned, so that the deslagging tank 19 is also connected to a manual sludge discharge valve 18.

After the treatment of the deslagging separation mechanism 3, most of solid waste in the restaurant wastewater is separated, the rest restaurant wastewater mainly comprises sewage and grease, in order to separate the sewage and the grease, the device further comprises an oil-water separation mechanism 1, the oil-water separation mechanism 1 comprises an oil-water separation tank which is arranged below the deslagging tank 19 and is communicated with the deslagging tank 19, and the top of the oil-water separation tank is sealed by an inverted cone-shaped top cover 17. The restaurant wastewater treated by the deslagging separation mechanism 3 flows downwards into the oil-water separation box, because the density of oil is small and the oil and water are incompatible, grease can float on the surface of the wastewater, and the grease can be gathered together by arranging the inverted conical top cover 17, so that the grease can be conveniently removed later.

Referring to fig. 6, after the oil floats in the oil-water separation tank, in order to remove the oil, the apparatus further includes an oil scraping mechanism 2, wherein the oil scraping mechanism 2 includes an oil scraping tank 25 disposed above the oil-water separation tank and communicated with the oil-water separation tank, the oil scraping tank 25 is communicated with a main oil discharging pipe 31, a chain 27 is rotatably disposed in the oil scraping tank 25, the chain 27 is fixedly connected with a plurality of oil scraping plates 28, and the chain 27 drives the oil scraping plates 28 to push waste oil in the oil-water separation tank into the main oil discharging pipe 31 in the rotation process of the chain 27. After the grease in the oil-water separation tank floats, the chain 27 is utilized to drive the grease scraping plate 28 to move, the grease scraping plate 28 is firstly contacted with the grease in the moving process, so that the grease is adhered on the grease scraping plate 28 and synchronously moves along with the grease scraping plate 28, and then the grease scraping plate 28 throws the grease into the main oil discharging pipe 31 after reaching the position of the main oil discharging pipe 31, so that oil discharging is realized. Correspondingly, the chain 27 is supported by at least one driving wheel 26 and at least one driven wheel, and the driving wheel 26 is connected with a motor for driving the chain 27 to rotate, and in order to ensure the stability of the chain 27, at least one tensioning wheel should be further arranged, which belongs to the common prior art and is not described herein again.

In order to prevent sewage and grease from seeping out from the communication position of the oil-water separation tank and the oil scraping tank 25, the communication position is fastened and connected by adopting a sealing rubber strip through bolts, so that leakage phenomenon caused by inaccurate sealing is avoided, and later maintenance is facilitated.

Although grease can be continuously fed into the main oil drain pipe 31 by the wiper plate 28, when the amount of water in the oil-water separation tank is too large, grease may enter the wiper tank 25 upward, so that the grease cannot be removed in time, in order to cope with this, the wiper tank 25 is further communicated with the auxiliary oil drain pipe 30, and the auxiliary oil drain pipe 30 is located below the main oil drain pipe 31, and a wiper level gauge 29 is provided inside the wiper tank 25. The wiper level gauge 29 monitors the liquid level in the wiper tank 25 in real time, and when the liquid level reaches a set threshold value, the sub-drain pipe 30 is opened to rapidly drain the liquid in the wiper tank 25, thereby avoiding the occurrence of grease accumulation, and therefore, the sub-drain pipe 30 needs to be lower than the main drain pipe 31. The wiper level gauge 29 may be positioned higher, indicating that the liquid level has reached a preset threshold when the wiper level gauge 29 monitors the liquid level.

The equipment still includes sewage lifting mechanism 8, and sewage lifting mechanism 8 includes the header tank with the water oil separating case intercommunication, and the bottom slope of header tank is provided with the bottom plate, and the header tank still communicates bottom drain pipe 10 and overflow pipe 9 to overflow pipe 9 is located the top of bottom drain pipe 10. After the wastewater after oil scraping treatment enters the water collection tank, the wastewater firstly impacts on the inclined bottom plate and then flows downwards along the bottom plate, the bottom plate can be washed in the flowing process, the solidification of impurities on the bottom plate is avoided, and in the maintenance process, the residual wastewater in the water collection tank is conveniently discharged through the bottom drain pipe 10. By arranging the overflow pipe 9, the overflow effect can be realized, and overflow caused by excessive waste water in the water collecting tank is avoided.

After a period of use, some impurities will inevitably adhere to each tank, and in order to reduce the frequency and difficulty of manual cleaning, the apparatus further comprises a self-cleaning mechanism comprising a submersible pump 12 for providing cleaning water, the submersible pump 12 being in communication with a primary cleaning line 13, the primary cleaning line 13 being in communication with a first secondary cleaning line 14 and a second secondary cleaning line 24, wherein the first secondary cleaning line 14 extends into the oil-water separation tank, and the second secondary cleaning line 24 extends into the deslagging tank 19. After a period of use, clean water is pumped into the main cleaning pipeline 13 of the submersible pump 12, enters the oil-water separation tank through the first auxiliary cleaning pipeline 14 to wash the oil-water separation tank, enters the deslagging tank 19 through the second auxiliary cleaning pipeline 24 to wash the deslagging tank 19 and the auger slag remover 4, so that self-cleaning of equipment is realized, and frequency and difficulty of manual cleaning are remarkably reduced. The main cleaning pipeline 13 can also be communicated with a third auxiliary cleaning pipeline, and the third auxiliary cleaning pipeline extends into the oil scraping tank 25 to realize self-cleaning of the oil scraping tank 25. The same self-cleaning treatment mode can also be adopted for the water collection tank. The submersible pump 12 is also connected to a water supply line and an air floatation generator 11, which are well known in the art and will not be described in detail herein.

Considering that grease is solidified in a low temperature state, which results in difficulty in cleaning, in order to avoid solidification of grease, the main cleaning line 13 is provided with a constant temperature heater 16 and a temperature sensor 15. The cleaning water can be heated to a proper temperature by the constant temperature heater 16, so that the grease is kept in a liquid state, and the grease solidification caused by the too low cleaning water temperature is avoided, thereby improving the self-cleaning effect.

Considering that restaurant wastewater can give off bad smell, the outside of giving off can cause the pollution to surrounding environment, in order to avoid this condition, each box all can be linked together and have blast pipe 23 to all blast pipes 23 communicate jointly and have vent line 6, and vent line 6 can communicate air cleaning equipment, avoids peculiar smell air to give off and causes environmental pollution.

The device further comprises a control box 7 for controlling the mechanisms, wherein the control box 7 can be realized based on a PLC, and belongs to the mature prior art in the field, and the description is omitted here.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model.
