Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a wastewater separation device for catering. Background Technology

[0002] Food service wastewater is the sewage generated in the food processing, catering service, and tableware cleaning processes of the catering industry. It has distinct industry characteristics and is complex in composition, containing a large amount of food residue, animal and vegetable oils, proteins, starch, colloidal particles, and silt, and has a high oil content.

[0003] Existing wastewater separation devices for catering generally face the problem of decreased separation efficiency due to filter clogging during operation. Catering wastewater often contains larger solid residues such as rice grains, vegetable leaves, bone fragments, and grease clumps. These substances easily adhere to or become embedded in the filter pores as the wastewater flows through the filter. With increased usage time, the solid residues gradually accumulate, which not only reduces the effective filtration area of ​​the filter but may also form a filter cake layer that obstructs water flow, causing wastewater retention and reduced treatment efficiency. Furthermore, if the clogged filter is not cleaned in time, the organic matter in the residue will decompose and produce odors and breed bacteria, affecting the surrounding environment of the device and potentially causing a load impact on subsequent wastewater treatment processes. Therefore, improvements and optimizations are needed. Utility Model Content

The outer surface of the converter is fixedly connected to a flushing pipe connecting flange. An annular connecting pipe is fixedly installed on the inner wall of the separation tank. A connecting pipe is fixedly connected to the outer surface of the annular connecting pipe and they are interconnected. One end of the connecting pipe is fixedly connected to a diversion pipe. A nozzle is fixedly installed on the outer surface of the diversion pipe in a linear array. One end of the flushing pipe connecting flange is fixedly connected to a flushing pipe, and the other end of the flushing pipe is interconnected with the annular connecting pipe. A drain pipe is fixedly connected to the outer surface of the liquid extraction pipe connecting flange. A debris removal component is fixedly connected to the bottom side of the separation assembly.

[0006] As a preferred embodiment of this utility model, the separation assembly includes a filter screen fixedly installed at the bottom of the inner side of the separation tank, a motor bracket fixedly installed at the top of the separation tank, a motor fixedly installed inside the motor bracket with the motor's output shaft extending into the inner side of the separation tank, a rotating shaft fixedly connected to the end of the motor's output shaft, a stirring plate fixedly installed on the outer surface of the rotating shaft in a circumferential array, stirring blades fixedly installed on the outer surface of the stirring plate in a linear array on the side of the stirring plate, and a waste removal assembly fixedly connected to the bottom side of the filter screen.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes a centrifugal separation component to rapidly separate the oil-water mixture of catering wastewater into a separation tank. An external controller activates a water pump for directional drainage. Addressing the issue of decreased separation efficiency due to solid residue buildup on the separation component surface after long-term use, the system automatically switches to a cleaning mode: after closing the separation component and wastewater connection pipe, the converter pumps the residual mixture in the separation tank into a flushing pipe. A high-pressure water flow is formed through a ring-shaped connecting pipe, connecting pipe, diversion pipe, and nozzles, precisely flushing the outer surface of the separation component, causing the residue to fall to the inside. The residue is then discharged into an external receiving and collecting device via a waste removal component. This design eliminates the need for manual disassembly and cleaning, preventing residue blockage and ensuring continuous and efficient equipment operation. It also reduces manual maintenance costs and operational risks, achieving automation, energy saving, and environmental protection in catering wastewater treatment, effectively improving resource recycling rates and wastewater treatment quality.

[0014] 2. After the motor is started by the external controller, the rotating shaft links the stirring plate to rotate at high speed, causing the catering wastewater to generate centrifugal force in the filter screen, quickly separating the oil-water mixture and discharging it through the unblocking component. At the same time, the stirring blades rotate with the stirring plate to crush solid residues, reducing their adhesion and clogging of the outer surface of the filter screen, and continuously ensuring separation efficiency. After separation, the residues are conveniently discharged through the impurity removal component without manual cleaning. The entire system realizes the integrated operation of oil-water separation and residue treatment through mechanical linkage, reducing manual intervention, lowering the risk of equipment blockage, and improving resource recovery efficiency. It not only ensures the stability of catering wastewater treatment, but also reduces operation and maintenance costs, contributing to environmental protection and sustainable operation.

[0021] 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.

[0022] like Figures 1 to 5 As shown, this utility model provides a wastewater separation device for catering, including a separation tank 1. A separation component 5 is fixedly installed on the bottom inner side of the separation tank 1. A wastewater connecting pipe 9 is fixedly installed on the outer surface of the separation tank 1, and the wastewater connecting pipe 9 extends to the inner side of the separation tank 1. A support base 2 is fixedly installed at the bottom of the separation tank 1. A base plate 3 is fixedly installed at the bottom of the support base 2. A dredging component 4 is fixedly installed on the top of the base plate 3. The dredging component 4 includes a water pump frame 401 fixedly installed on the top of the base plate 3. A water pump 402 is fixedly installed on the top of the water pump frame 401. A converter 405 is fixedly connected to the side of the water pump 402. A suction pipe connecting flange 403 is fixedly connected to one side of the converter 405. One end of the suction pipe connecting flange 403 is fixedly connected to... A liquid extraction pipe 404 extends into and communicates with the interior of the separator 1. A flushing pipe connecting flange 406 is fixedly connected to the outer surface of the converter 405. An annular connecting pipe 408 is fixedly installed on the inner wall of the separator 1. A connecting pipe 409 is fixedly connected to the outer surface of the annular connecting pipe 408 and they are interconnected. A diversion pipe 410 is fixedly connected to one end of the connecting pipe 409. A nozzle 411 is fixedly installed on the outer surface of the diversion pipe 410 and is arranged in a linear array. A flushing pipe 407 is fixedly connected to one end of the flushing pipe connecting flange 406 and the other end of the flushing pipe 407 is interconnected with the annular connecting pipe 408. A drain pipe 412 is fixedly connected to the outer surface of the liquid extraction pipe connecting flange 403. A waste removal component 7 is fixedly connected to the bottom side of the separator 5.

[0023] When connected to an external catering wastewater connection pipe via wastewater connection pipe 9, the catering wastewater will be centrifuged by separation component 5. The oil-water mixture will then be thrown into the separation tank 1 by centrifugal force. At this time, the water pump 402 is started by the external controller, and the separated oil-water mixture will flow into the suction pipe 404 and then be discharged through the drain pipe 412. After prolonged separation, some solid residue will remain on the outer surface of separation component 5, weakening the separation effect. At this time, separation component 5 and wastewater connection pipe 9 are closed, and converter 405 is opened to allow... The remaining oil-water mixture inside the separator 1 is pumped into the flushing pipe 407 via the converter 405. The flushing pipe 407 then transmits high-pressure water to the annular connecting pipe 408. The annular connecting pipe 408 then transports the high-pressure oil-water mixture to the diversion pipe 410 via the connecting pipe 409. The mixture is then sprayed onto the outer surface of the separator 5 through the nozzle 411, causing the remaining solid residue to fall into the inner side of the separator 5. The impurity discharge component 7 is then opened, allowing the solid residue to fall into the external receiving and collecting device. This effectively maintains the separation effect of the separator 5 and prevents it from being blocked by solid residue, thus affecting its separation.

[0024] After the catering wastewater is centrifuged by the separation component 5, the oil-water mixture is quickly separated into the separation tank 1 by centrifugal force. The external controller starts the water pump 402 to achieve directional drainage and discharge. In response to the problem of decreased separation efficiency caused by the accumulation of solid residue on the surface of the separation component 5 after long-term use, the system can automatically switch to the cleaning mode: after the separation component 5 and the wastewater connection pipe 9 are closed, the converter 405 pumps the residual mixture in the separation tank 1 into the flushing pipe 407. Through the annular connecting pipe 408, the connecting pipe 409, the diversion pipe 410 and the nozzle 411, a high-pressure water flow is formed to precisely flush the outer surface of the separation component 5, causing the residue to fall to the inside. Then, it is discharged into the external receiving and collection device through the impurity discharge component 7. This design eliminates the need for manual disassembly and cleaning, avoids residue blockage affecting the separation effect, ensures continuous and efficient operation of the equipment, and reduces manual maintenance costs and operational risks. It realizes the automation, energy saving and environmental protection of catering wastewater treatment, and effectively improves the resource recycling rate and wastewater treatment quality.

[0025] The separation component 5 includes a filter screen 503 fixedly installed at the bottom of the inner side of the separation tank 1. A motor bracket 501 is fixedly installed at the top of the separation tank 1. A motor 502 is fixedly installed inside the motor bracket 501, and the output shaft of the motor 502 extends to the inner side of the separation tank 1. A rotating shaft 505 is fixedly connected to the end of the output shaft of the motor 502. A stirring plate 506 is fixedly installed on the outer surface of the rotating shaft 505, and the stirring plate 506 is arranged in a circumferential array. Stirring blades 507 are fixedly installed on the outer surface of the stirring plate 506, and the stirring blades 507 are fixedly installed on the side of the stirring plate 506 in a linear array. A waste removal component 7 is fixedly connected to the bottom side of the filter screen 503.

[0026] When the external controller starts the motor 502, its output shaft will drive the rotating shaft 505 to rotate. When the rotating shaft 505 rotates, it will drive the stirring plate 506 to start rotating. When the stirring plate 506 starts rotating, it will cause the catering wastewater inside the filter screen 503 to generate centrifugal force, causing the oil-water mixture to be thrown out of the filter screen 503 into the separation tank 1 and discharged outward by the unblocking component 4. At the same time, when the stirring plate 506 rotates, it will drive the stirring blade 507 to start rotating. When the stirring blade 507 starts rotating, it will crush the solid residue in the catering wastewater and reduce the clogging of the outer surface of the filter screen 503, thereby maintaining the separation effect. After the separation is completed, the residue is discharged outward by the impurity removal component 7.

[0027] After the motor 502 is started by the external controller, the rotating shaft 505 is linked to the stirring plate 506 to rotate at high speed, which generates centrifugal force in the filter screen 503, quickly separating the oil and water mixture and discharging it through the unblocking component 4. At the same time, the stirring blade 507 rotates with the stirring plate 506 to crush solid residues, reducing their adhesion and clogging of the outer surface of the filter screen 503, and continuously ensuring separation efficiency. After separation, the residues are conveniently discharged through the impurity discharge component 7 without manual cleaning. The entire system realizes the integrated operation of oil-water separation and residue treatment through mechanical linkage, reducing manual intervention, reducing the risk of equipment blockage, and improving resource recovery efficiency. It not only ensures the stability of catering wastewater treatment, but also reduces operation and maintenance costs, and contributes to environmental protection and sustainable operation.

[0028] The impurity removal component 7 includes an impurity removal pipe 701 fixedly connected to the bottom side of the filter screen 503 and the impurity removal pipe 701 passes through the filter screen 503 and the separation tank 1. A valve 702 is threadedly connected to the inside of the separation tank 1.

[0029] By rotating valve 702, valve 702 is disengaged from discharge pipe 701. Then, with the cooperation of unblocking component 4, the solid residue remaining inside filter screen 503 is discharged to the outside, maintaining the separation effect of filter screen 503.

[0030] The bottom inner side of the separator 1 is fixedly equipped with a guide plate 6, which is narrow at the top and wide at the bottom, with a low outer perimeter and a filter screen 503 passing through it.

[0031] The guide plate 6 is narrow at the top and wide at the bottom with a low outer perimeter, which allows the oil-water mixture thrown out by the filter screen 503 to be quickly discharged by the unblocking component 4, reducing the amount of oil-water mixture remaining inside the separator tank 1.

[0032] The top of the separator 1 is fixedly equipped with a motor protective cover 8, and the motor 502 is located inside the motor protective cover 8.

[0033] By positioning the motor 502 inside the motor protective cover 8, the motor 502 can be effectively protected in all directions, preventing it from being easily damaged by external physical forces.

[0034] The filter screen 503 has a partition ring 504 fixedly installed on its top, and the filter screen 503 is conical in shape.

[0035] A separator ring 504 is fixedly installed on the top of the filter screen 503, which allows some of the unseparated catering wastewater to enter the separation tank 1 during separation.

[0036] The support base 2 is fixedly installed around the bottom of the separation tank 1 and is fixedly connected to the base plate 3.

[0037] The support base 2 is fixedly installed around the bottom of the separation tank 1 and is fixedly connected to the base plate 3, which can effectively increase the stability of the entire device and avoid it from being easily affected by external physical influences.

[0038] Working principle and usage process of this utility model:

[0039] When connected to an external catering wastewater connection pipe via wastewater connection pipe 9, the catering wastewater will be centrifuged by separation component 5. The oil-water mixture will then be thrown into the separation tank 1 by centrifugal force. At this time, the water pump 402 is started by the external controller, and the separated oil-water mixture will flow into the suction pipe 404 and then be discharged through the drain pipe 412. After prolonged separation, some solid residue will remain on the outer surface of separation component 5, weakening the separation effect. At this time, separation component 5 and wastewater connection pipe 9 are closed, and converter 405 is opened to allow... The remaining oil-water mixture inside the separator 1 is pumped into the flushing pipe 407 via the converter 405. The flushing pipe 407 then transmits high-pressure water to the annular connecting pipe 408. The annular connecting pipe 408 then transports the high-pressure oil-water mixture to the diversion pipe 410 via the connecting pipe 409. The mixture is then sprayed onto the outer surface of the separator 5 through the nozzle 411, causing the remaining solid residue to fall into the inner side of the separator 5. The impurity discharge component 7 is then opened, allowing the solid residue to fall into the external receiving and collecting device. This effectively maintains the separation effect of the separator 5 and prevents it from being blocked by solid residue, thus affecting its separation.

[0040] When the external controller starts the motor 502, its output shaft will drive the rotating shaft 505 to rotate. When the rotating shaft 505 rotates, it will drive the stirring plate 506 to start rotating. When the stirring plate 506 starts rotating, it will cause the catering wastewater inside the filter screen 503 to generate centrifugal force, causing the oil-water mixture to be thrown out of the filter screen 503 into the separation tank 1 and discharged outward by the unblocking component 4. At the same time, when the stirring plate 506 rotates, it will drive the stirring blade 507 to start rotating. When the stirring blade 507 starts rotating, it will crush the solid residue in the catering wastewater and reduce the clogging of the outer surface of the filter screen 503, thereby maintaining the separation effect. After the separation is completed, the residue is discharged outward by the impurity removal component 7.
