Description

Technical Field

[0001] This utility model relates to the field of oil spill thickness monitoring technology, and in particular to a floating oil collection and discharge device with an oil spill thickness monitoring mechanism. Background Technology

[0002] Currently, floating oil collection devices are commonly used in oily wastewater treatment ponds, industrial sedimentation tanks, and river and water pollution control to collect floating oil on the liquid surface. Existing devices typically rely on floats or pontoons to allow the oil collection port to float with changes in the liquid level, thus ensuring that the collection point remains on the liquid surface. However, most of these devices can only directly collect the oil layer on the liquid surface and lack the ability to monitor the thickness of the floating oil.

[0003] A Chinese patent has been published: an oil spill collection device for waste liquid treatment, patent publication number: CN216890381U. This patent "includes a treatment tank, with support plates bolted to both sides of the top of the treatment tank. A moving mechanism is rotatably connected to the two support plates through bearings. With the cooperation of an oil scraper, the oil spill on the surface of the waste liquid can be cleaned, and then the cleaned oil spill is collected into the collection tank through a through hole. This achieves a fast oil spill collection speed and facilitates the collection of oil spill by the user. A stepper motor is provided to provide driving force."

[0004] While this device can expand the oil scraping range of the oil collection device by moving the scraper along with the screw rotation on the surface of the treatment tank and avoiding the problem of the oil collection device constantly moving, the lack of an oil thickness monitoring mechanism makes it impossible to monitor and judge the thickness of the oil layer on the liquid surface. When the oil layer is thin, blindly starting the oil collection device may scrape in a large amount of water, reducing the oil-water separation efficiency. When the oil layer is thick, since the device cannot automatically identify and start the oil collection process, operators often need to manually detect the oil layer thickness and manually control the oil collection device to start. This not only results in high labor intensity and slow response, but may also lead to excessive oil retention time, causing diffusion and pollution, seriously affecting the oil collection effect and environmental safety. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a floating oil collection and discharge device with an oil thickness monitoring mechanism, so as to solve the problem that the existing equipment does not have an oil thickness monitoring mechanism, which makes it impossible to monitor and judge the thickness of the oil layer on the liquid surface, requiring manual operation of the equipment, resulting in high labor intensity and untimely response.

[0009] Preferably, an oil suction roller is rotatably connected between the inner walls of the separation box, and a motor is fixedly connected to the side wall of the separation box.

[0026] like Figures 1 to 6 As shown, a floating oil collection and discharge device with an oil thickness monitoring mechanism includes a collection tank 1, inside which a floating plate 2 is placed. The floating plate 2 has a triangular shape, and three corners of the floating plate 2 are fixedly connected to floating balls 3 for driving the floating plate 2 to float on the oil level. The bottom of the floating plate 2 is fixedly connected to an oil collection pipe 4, and the top of the inside of the oil collection pipe 4 is connected to the top of the floating plate 2. The side wall of the floating plate 2 is provided with a monitoring mechanism for monitoring the oil thickness.

[0027] Further, see attached document. Figures 2 to 6As shown, the monitoring mechanism includes a fixed plate 5 fixedly connected to the side wall of the floating plate 2. Two sliding plates 6 are fixedly connected to the side wall of the fixed plate 5. A mid-float component 7 is slidably connected between the inner walls of the two sliding plates 6. An oil level gauge 8 is fixedly connected to the top of the mid-float component 7. A fixed rod 9 is fixedly connected to the side wall of the fixed plate 5. An indicator arrow 10 is fixedly connected to the side wall of the fixed rod 9. The indicator arrow 10 has a U-shaped structure and slides on the side wall of the oil level gauge 8. A pressure sensor 11 is fixedly connected to the top of the fixed rod 9. A pressure plate 12 is fixedly connected to the side wall of the oil level gauge 8. The pressure sensor 11 and the pressure plate 12 are on the same vertical line. A separation box 13 is fixedly installed on the side wall of the collection tank 1. A water pump 14 is fixedly connected to the side wall of the separation box 13. The input and output ends of the water pump 14 are both fixedly connected to... A conveying pipe 15 is connected to the bottom of the oil collection pipe 4 at the input end of the water pump 14. The conveying pipe 15 at the output end of the water pump 14 extends into the bottom of the inner wall of the separation box 13. A water storage tank 16 is fixedly connected to the side wall of the separation box 13. An oil suction roller 17 is rotatably connected between the inner walls of the separation box 13. A motor 18 is fixedly connected to the side wall of the separation box 13. The output end of the motor 18 passes through the inner wall of the separation box 13 and is fixedly connected to the shaft of the oil suction roller 17. A through groove 19 is opened on the side wall of the inner wall of the separation box 13 near the oil suction roller 17. An oil guide plate 20 is fixedly connected to the bottom of the inner wall of the through groove 19. The oil guide plate 20 is inclined. A rubber scraper 21 is fixedly installed on the side of the oil guide plate 20 near the oil suction roller 17. The side wall of the rubber scraper 21 is attached to the outer wall of the oil suction roller 17.

[0028] First, place the floating plate 2 and the floating ball 3 on top of the oil and water in the collection tank 1. The floating ball 3 drives the floating plate 2 to float, and the oil surface will submerge the floating plate 2. When it is necessary to monitor the thickness of the oil, since the density of water is greater than that of oil, the water is at the bottom and the oil is at the top of the water. The material of the middle float 7 is polypropylene, which has a density greater than that of oil but less than that of water. Therefore, it can float stably between the water and the oil. At this time, the thickness of the oil layer can be intuitively judged by the position of the marker arrow 10 on the oil measuring gauge 8. As the thickness of the oil layer increases, the floating plate 2 will rise and drive the fixed rod 9 and the marker arrow 10 to change their positions, thereby realizing real-time monitoring of the oil layer thickness. When the fixed rod 9 drives the pressure sensor 11 to rise and contact the pressure plate 12, the pressure sensor 11 will send a control signal to the water pump 14 and the motor 18 after detecting the signal.

[0029] The water pump 14 starts to draw the oil-water mixture floating in the oil-collecting pipe 4 and transports it to the separation tank 13 through the conveying pipe 15. At the same time, the motor 18 drives the oil suction roller 17 to rotate. When the oil in the separation tank 13 comes into contact with the oil suction roller 17, the oil suction roller 17 has a polydimethylsiloxane coating on its outer surface. It has low surface energy and strong hydrophobicity, so it only adsorbs oil and not water. The adsorbed oil is scraped off by the rubber scraper 21 during the rotation. The scraped oil flows along the oil guide plate 20 and is guided. It can be placed in a collection container for centralized collection and treatment. During the oil-water separation process, the water, due to its higher density, will flow into the water storage tank 16 through the separation tank 22 and be discharged back into the collection tank 1 through the outlet 23. In addition, a filter ring 24 is also provided on the top of the floating plate 2 near the top edge of the oil-collecting pipe 4 to perform preliminary filtration of the floating oil entering the oil-collecting pipe 4, thereby ensuring that the oil-water mixture entering the separation tank 13 is purer and preventing impurities from entering the oil-collecting pipe 4 and causing blockage.

[0030] This device enables real-time detection of oil thickness through a monitoring mechanism and is linked to the oil recovery process. It solves the problem that existing equipment does not have an oil thickness monitoring mechanism, making it impossible to monitor and judge the oil layer thickness. It effectively avoids the problem of blindly starting when the oil layer is thin, which leads to excessive water entering and reducing the separation efficiency, and the problem of needing manual detection and starting when the oil layer is thick because it cannot be automatically identified. This reduces labor intensity, improves response timeliness, avoids oil residue and diffusion pollution, and significantly improves oil recovery effect and environmental safety.

[0031] Further, see attached document. Figure 6 As shown, the bottom side wall of the water storage tank 16 is provided with a separation groove 22 that is connected to the separation box 13, and the side wall of the water storage tank 16 is connected with a water outlet 23.

[0032] This achieves effective separation of oil and water, preventing oil from mixing back into the water and thus improving the efficiency of oil-water separation. At the same time, the water storage tank 16 is equipped with a water outlet 23, which can discharge the separated water in a timely manner and return it to the collection tank 1 to form a cycle treatment, reduce water waste, and improve the environmental protection and continuous operation of the entire device.

[0033] Further, see attached document. Figure 2 As shown, a filter ring 24 for filtering oil is fixedly connected to the top of the float plate 2 near the top edge of the oil collection pipe 4.

[0034] By setting a filter ring 24 at the top edge of the oil collection pipe 4, the floating oil entering the oil collection pipe 4 can be initially filtered, blocking any impurities, floating objects or larger particles that may be carried in it from entering the subsequent separation process. This prevents these impurities from clogging the conveying pipe 15 or affecting the normal adsorption effect of the oil suction roller 17, thereby ensuring the stability and reliability of the entire oil-water separation process and improving the purity of the collected oil.

[0035] Further, see attached document. Figure 4 As shown, the buoy 7 is made of polypropylene and is located between oil and water;

[0036] Because the density of polypropylene is greater than that of oil but less than that of water, the buoy 7 can naturally and stably float between the oil layer and the water layer, thereby achieving accurate positioning and monitoring of the oil layer thickness. At the same time, it provides accurate basis for the subsequent automatic control of the water pump 14 and motor 18 to start, improving the intelligence level and working efficiency of the oil recovery device.
