Description

Technical Field

[0001] The utility model relates to the technical field of oil-water separation treatment, and particularly relates to an oil-water separation harvesting and metering device. Background Technique

[0002] Oil-water separation is based on the density difference or different chemical properties of water and oil, and uses the principle of pump sedimentation or other physical and chemical reactions to remove impurities or complete the separation of oil and water. Now it is mainly divided into two types: catering oil-water separators and industrial oil-water separators. The common catering oil-water separation equipment is to separate the oil-water mixed sewage of kitchen waste generated during the catering process through filtering impurities and oil-water separation, and separate, recycle and discharge the impurities, waste oil and separated water.

[0003] After retrieval, the "environmentally friendly and energy-saving oil-water separation detection platform" with the patent publication number of CN208984391 U includes a detection box and an oil-water separator. One end of an oil outlet pipe is connected to the oil outlet of the oil-water separator, and the other end of the oil outlet pipe extends into the detection box and is connected to a first storage oil tank. The oil in the sampling bottle can be discharged through the first drain pipe. By using the sampling bottle, the amount of oil taken out each time can be almost the same, and the same amount of oil sampled each time can be saved for future statistics.

[0004] The above solution adopts the method of quantitative sampling, but the steps of replacing the sampling bottle after taking out the oil are cumbersome, resulting in a reduction in the harvesting efficiency. Content of the Utility Model

[0005] The purpose of the utility model is to provide an oil-water separation harvesting and metering device to solve the above problems.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An oil-water separation harvesting and metering device includes an oil-water separation tank and a support frame. An oil phase pipe and a water phase pipe are respectively connected to the top end and the bottom end of the oil-water separation tank, and control valves are arranged on both the oil phase pipe and the water phase pipe.

[0008] Two groups of power components and a turntable are installed on the support frame. A first collection pipe and a second collection pipe are respectively arranged on the two turntables, and the pipe orifices of the two control valves respectively face the first collection pipe and the second collection pipe.

[0009] As a preferred technical solution of the present application, the control valve includes a valve body, a sealing partition, a cylinder and a sealing rod. A first flow channel and a second flow channel are arranged inside the valve body. The pipe orifices of the oil phase pipe and the water phase pipe are connected to the corresponding first flow channels, and the first flow channel is communicated with the second flow channel.

[0010] The sealing partition is arranged in the second flow channel. The cylinder is fixed to the outer wall of the valve body through a bracket. One end of the sealing rod is connected to the telescopic rod of the cylinder, and the other end of the sealing rod penetrates into the valve body and passes through the sealing partition.

[0011] As a preferred technical solution of the present application, a limiting ring is further fixed on the inner wall of the second flow channel, and the connection between the first flow channel and the second flow channel is located between the sealing partition and the limiting ring.

[0012] As a preferred technical solution of the present application, an expansion head is fixed on the port of the sealing rod inside the valve body. The outer diameter of the expansion head is larger than the outer diameter of the sealing rod, and the outer diameter of the expansion head is the same as the inner diameter of the limiting ring.

[0013] As a preferred technical solution of the present application, the number of the first collection pipes and the second collection pipes is the same and they are arranged in a surrounding manner on the turntable.

[0014] As a preferred technical solution of the present application, the power assembly includes a reduction motor, a rotating shaft, and a metering platform. The bottom surface of the metering platform is fixed to the support frame. A ring groove is arranged on the metering platform. The shaft of the reduction motor is connected to one end of the rotating shaft, and the other end of the rotating shaft passes through the center of the ring groove and is fixed to the center of the bottom surface of the turntable.

[0015] As a preferred technical solution of the present application, sleeves for inserting the second collection pipes and the first collection pipes are fixed on the turntable.

[0016] Technical effects and advantages of the present utility model:

[0017] The oil and water are separated in the oil-water separation tank. Since the oil floats on the surface of the water and the height of the oil-water separation tank is higher than that of the first collection pipe and the second collection pipe, during harvesting, the first collection pipe and the second collection pipe move to directly below the two control valves. Under the action of the pump, the oil and water flow into the first collection pipe and the second collection pipe respectively in the oil-phase pipe and the water-phase pipe. When the collected oil or water reaches the liquid level of the liquid level sensor, the cylinder drives the telescopic rod to extend and the expansion head is inserted into the limiting ring to seal the corresponding control valve, preventing the oil or water from flowing down continuously. Another device continues to be used. The reduction motor drives the corresponding turntable to rotate, rotating the first collection pipe or the second collection pipe at the next position to directly below the control valve, and then the cylinder controls the telescopic rod to shorten and the expansion head disengages from the limiting ring, continuing to achieve the harvesting of the oil or water. Uninterrupted harvesting is achieved through the first collection pipe and the second collection pipe, improving the harvesting efficiency. By setting a plurality of first collection pipes and second collection pipes, the quality data of the oil and water harvested at different times can be collected while metering, so that subsequent optimization can be carried out on the above-mentioned harvesting data to achieve the best harvesting quality.

Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 - 4 , an oil-water separation and harvesting metering device, including an oil-water separation tank 1 and a support frame 2. The top and bottom of the oil-water separation tank 1 are respectively connected with an oil phase pipe 3 and a water phase pipe 4. Control valves 5 are arranged on both the oil phase pipe 3 and the water phase pipe 4; Two groups of power assemblies 6 and a turntable 7 are installed on the support frame 2. The two turntables 7 are respectively provided with a first collection pipe 8 and a second collection pipe 9. The pipe orifices of the two control valves 5 respectively face the first collection pipe 8 and the second collection pipe 9.

[0025] Oil and water are separated in the oil-water separation tank 1. Since the oil floats on the surface of the water, the height of the oil-water separation tank 1 is higher than that of the first collection pipe 8 and the second collection pipe 9. Under the action of a pump, the oil and water respectively flow into the first collection pipe 8 and the second collection pipe 9 in the oil phase pipe 3 and the water phase pipe 4. The control valve 5 is used to control the on-off of the oil phase pipe 3 and the water phase pipe 4.

[0026] The control valve 5 includes a valve body 51, a sealing partition 52, a cylinder 53 and a sealing rod 54. A first flow channel 511 and a second flow channel 512 are arranged inside the valve body 51. The pipe orifices of the oil phase pipe 3 and the water phase pipe 4 are connected to the corresponding first flow channel 511, and the first flow channel 511 is communicated with the second flow channel 512;

[0027] The sealing baffle 52 is arranged in the second flow channel 512, the cylinder 53 is fixed to the outer wall of the valve body 51 through a bracket, one end of the sealing rod 54 is connected to the telescopic rod of the cylinder 53, and the other end of the sealing rod 54 penetrates into the valve body 51 and passes through the sealing baffle 52.

[0028] A limiting ring is also fixed on the inner wall of the second flow channel 512 , and the connection between the first flow channel 511 and the second flow channel 512 is located between the sealing partition 52 and the limiting ring.

[0029] A flaring end is fixed to the port of the sealing rod 54 located inside the valve body 51 . The outer diameter of the flaring end is larger than the outer diameter of the sealing rod 54 , and the outer diameter of the flaring end is the same as the inner diameter of the limit ring.

[0030] The cylinder 53 is used to control the movement of the sealing rod 54 and the expansion head in the second flow channel 512 to control whether the second flow channel 512 is open. When the second flow channel 512 needs to be sealed, the cylinder 53 drives the telescopic rod to extend and push the sealing rod 54 and the expansion head toward the limit ring. The expansion head moves and inserts into the limit ring, thereby sealing the limit ring. At this time, the second flow channel 512 is also sealed, and the liquid flowing in the first flow channel 511 cannot be blocked.

[0031] The cylinder 53 drives the telescopic rod to shorten and push the sealing rod 54 and the expansion head toward the limit ring. The expansion head moves out of the limit ring, thereby opening the limit ring position. At this time, the second flow channel 512 is also opened, and the liquid flowing in the first flow channel 511 can flow out from the second flow channel 512.

[0032] The number of the first collecting tubes 8 and the second collecting tubes 9 is the same and they are arranged in a surrounding manner on the rotating disk 7 .

[0033] The power assembly 6 includes a reduction motor 61, a rotating shaft 62, a support frame 2 and a metering platform 63. The bottom surface of the metering platform 63 is fixed to the support frame 2. An annular groove is provided on the metering platform 63. The shaft of the reduction motor 61 is connected to one end of the rotating shaft 62. The other end of the rotating shaft 62 passes through the center of the annular groove and is fixed to the center of the bottom surface of the turntable 7. The turntable 7 is used to be embedded in the annular groove and keep the top surface of the turntable 7 and the metering platform 63 flush. The bottom of the turntable 7 contacts the annular groove through the ball bearings, which serves the purpose of support and can reduce the friction of sliding.

[0034] Sleeves for inserting the second collecting tube 9 and the first collecting tube 8 are fixed on the turntable 7 .

[0035] Liquid level sensors are fixed on the inner walls of the first collecting tube 8 and the second collecting tube 9 , and the liquid level sensors are wirelessly connected to the control microcontroller on the metering platform 63 , and the control microcontroller is connected to the cylinder 53 and the reduction motor 61 through wires.

[0036] The reduction motor 61 drives the rotation of the rotating shaft 62, thereby realizing the rotation of the turntable 7. During harvesting, the first collection pipe 8 and the second collection pipe 9 are moved to directly below the two control valves 5, and the oil and water in the oil phase pipe 3 and the water phase pipe 4 flow into the first collection pipe 8 and the second collection pipe 9 respectively. When the oil or water collected in the first collection pipe 8 or the second collection pipe 9 reaches the liquid level of the liquid level sensor, the control single-chip microcomputer sends a control signal to the cylinder 53 and the reduction motor 61. The cylinder 53 drives the telescopic rod to extend and the expansion head is inserted into the limit ring to seal the corresponding control valve 5 to prevent the oil or water from flowing down continuously. Then, the reduction motor 61 drives the turntable 7 to rotate, rotating the first collection pipe 8 or the second collection pipe 9 at the next position to directly below the control valve 5. Then, the cylinder 53 controls the telescopic rod to shorten and the expansion head disengages from the limit ring to continue the harvesting of the oil or water.

[0037] By providing two groups of the first collection pipe 8 and the second collection pipe 9 for collecting oil and water, the two operate independently, and the full harvesting of one does not affect the use of the other device. Moreover, continuous harvesting is achieved through the first collection pipe 8 and the second collection pipe 9. By providing a plurality of the first collection pipe 8 and the second collection pipe 9, the quality data of the oil and water harvested at different times can be collected while measuring, so that subsequent optimization can be carried out on the above-mentioned harvesting data to achieve the best harvesting quality.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
