Description

Technical Field

[0001] The utility model relates to the technical field of water-oil detection devices, in particular to a water-oil detection device with controllable detection time. Background Art

[0002] Oil-water detection usually refers to "monitoring the concentration of oil substances in water bodies". These oil substances may come from industrial wastewater, domestic sewage discharge, animal decomposition and other sources. The oil-water detection device is a device specially used to measure the content of oil substances in water bodies. It can obtain the concentration of oil in water in real time, thereby helping relevant departments to evaluate and monitor water quality. The purpose of oil-water detection is to monitor the quality, safety and pollution level of water bodies, ensure the safety of water quality at water sources, and promptly discover and treat oil pollutants to avoid impacts on human health. At the same time, by monitoring the oil substances in water bodies, the location of the pollution source and the type of pollutants can be determined, and measures can be taken to reduce or eliminate pollution, and the impact of environmental changes on water bodies can be understood. In the process of use, most of the existing oil-water detection devices use single-layer separation filtration. If the rotation speed is too slow, it may lead to poor water-oil separation effect, and re-sampling and detection may be required, which reduces the detection efficiency and affects the work process; Therefore, we propose a water-oil detection device with controllable detection time to solve the above-mentioned problems. Utility Model Content

[0003] In order to overcome the problem that the existing water-oil detection devices mostly use single-layer separation filtration during use, if the rotation speed is too slow, it may lead to poor water-oil separation effect, and re-sampling and detection may be required, which reduces the detection efficiency and thus affects the work progress.

[0004] The technical solution of the utility model is: a water-oil detection device with controllable detection time, comprising a tank body, a filter assembly and a separation assembly; a filter assembly for filtering a water-oil mixture sample to be detected to remove large particles in the sample is provided on the upper inner side of the tank body, a separation assembly for separating oil and water by centrifugal force generated by high-speed rotation for easy detection is provided below the filter assembly, the separation assembly comprises a first separation barrel, a second separation barrel, a third separation barrel, an electrochemical sensor, a rotating sleeve, a rotating column and a variable speed motor, and an electrochemical sensor for determining oil content by electrochemical reaction is installed on the inner bottom of the first separation barrel.

[0005] Preferably, when the filtered water-oil mixture sample gradually and completely enters the first separation barrel, the display panel is controlled and driven by the variable speed motor, and the rotating column drives the rotating sleeve to rotate, so that the first separation barrel, the second separation barrel and the third separation barrel separate the oil and water through the centrifugal force generated by high-speed rotation. In this process, through the adjustment of the display panel and according to the operator's need for detection time, the variable speed motor can continuously increase the rotation speed, so that the water-oil mixture sample passes through multi-stage separation and reaches complete separation of water and oil, thereby accelerating the work process, ensuring timely detection of changes in water quality, and providing a scientific basis for taking corresponding treatment and protection measures.

[0006] Preferably, a display panel is installed on one side of the exterior of the tank body, four groups of arc-shaped snap-in grooves for positioning and connecting the filter assembly are arranged around the upper inner wall of the tank body, a circular sealing cover is arranged on the upper part of the tank body, and a liquid inlet pipe is installed in the middle part of the upper end of the circular sealing cover. The water-oil mixture sample to be tested passes through the liquid inlet pipe through the connecting pipe and enters the hole filter barrel for preliminary filtration, so as to remove large particles in the water-oil mixture sample.

[0007] Preferably, a handle fixedly connected to the circular sealing cover is provided on each side of the liquid inlet pipe, a circular sealing ring for increasing the sealing is installed at the edge of the lower end of the circular sealing cover, and a connecting pipe is installed in the middle part of the lower end of the circular sealing cover corresponding to the liquid inlet pipe. First, the circular sealing cover is opened by lifting the handle, and then after the hole filter barrel is installed, the handle is lifted, and the circular sealing ring drives the circular sealing cover to fit and connect with the tank body along the inner wall of the tank body, thereby the circular sealing ring can increase the sealing and prevent the water-oil mixture from being affected by the outside world during filtering and separation.

[0008] Preferably, a plurality of groups of arc-shaped columns are installed around the lower edge of the tank body, a delivery pipe is installed at the lower end of the tank body, a telescopic valve is sleeved on the outside of the connection between the delivery pipe and the tank body, and an electromagnetic control valve is installed on the outer side of the telescopic valve. When the filtration and separation is completed, the telescopic valve is slowly opened through the control of the display panel and the electromagnetic control valve, and the separated wastewater flows out through the delivery pipe, which is convenient for unified treatment. In this process, the arc-shaped columns firmly support the tank body, thereby improving the stability and operability of the water-oil detection device.

[0009] Preferably, the filter assembly includes a porous filter barrel and an arc-shaped clamping plate. Four groups of arc-shaped clamping plates are installed around the outer upper end of the porous filter barrel. The arc-shaped clamping plates drive the porous filter barrel to be positioned and connected with the tank body through the arc-shaped clamping groove. When the circular seal is opened, the porous filter barrel is picked up, and the arc-shaped clamping plates drive the porous filter barrel to be positioned and connected with the tank body through the arc-shaped clamping groove, thereby improving the practicality and flexibility of the water-oil detection device.

[0010] Preferably, a second separation barrel is installed in the middle of the inner side of the third separation barrel, and a first separation barrel is installed in the middle of the inner side of the second separation barrel. The first separation barrel, the second separation barrel and the third separation barrel are all linearly arranged with a plurality of circular holes for liquid to pass through. Under the action of centrifugal force, the water in the water-oil mixture sample will move outward through the circular holes under the action of centrifugal force, while the oil with lower density is closer to the center of rotation, thereby achieving the effect of water-oil separation. After the wastewater is discharged, the oil separated in the third separation barrel is determined by electrochemical reaction through the action of the electrochemical sensor, and the detected value is reflected on the display panel for easy observation and recording.

[0011] Preferably, a rotating sleeve is installed in the middle of the lower end of the third separation barrel, and a rotating column is installed inside the rotating sleeve. A variable speed motor is installed at the lower end of the rotating column. When the filtered water-oil mixture sample gradually and completely enters the first separation barrel, the rotating column drives the rotating sleeve to rotate through the control of the display panel and the drive of the variable speed motor. As a result, the first separation barrel, the second separation barrel and the third separation barrel separate the oil and water through the centrifugal force generated by high-speed rotation. In this process, through the adjustment of the display panel, according to the operator's needs for detection time, the variable speed motor can continuously increase the rotation speed, so that the water-oil mixture sample can be separated through multiple stages to achieve complete separation of water and oil, thereby accelerating the work progress.

[0012] Beneficial effects of the utility model:

[0013] 1. According to the previous use of water-oil detection devices, most of them adopt single-layer separation filtration. If the rotation speed is too slow, the water-oil separation effect may be poor, and re-sampling and detection may be required, which reduces the detection efficiency and affects the work progress. The difference is that when the filtered water-oil mixture sample gradually and completely enters the first separation barrel, through the control of the display panel and the drive of the variable speed motor, the rotating column drives the rotating sleeve to rotate, so that the first separation barrel, the second separation barrel and the third separation barrel separate the oil and water through the centrifugal force generated by high-speed rotation. In this process, through the adjustment of the display panel, according to the operator's need for detection time, the variable speed motor can continuously increase the rotation speed, so that the water-oil mixture sample can pass through multi-stage separation to achieve complete separation of water and oil, speed up the work progress, ensure timely detection of water quality changes, and provide a scientific basis for taking corresponding treatment and protection measures.

[0014] 2. Lift the handle, and the circular sealing ring drives the circular sealing cover to fit along the inner wall of the tank body and connect with the tank body. The circular sealing ring can increase the sealing performance and prevent the water-oil mixture from being affected by the outside world during filtration and separation. Then, the water-oil mixture sample to be tested passes through the liquid inlet pipe and the connecting pipe into the hole filter barrel for preliminary filtration to remove large particles in the water-oil mixture sample.

[0025] See also Figure 4-6 In this embodiment, the filter assembly 2 includes a porous filter barrel 201 and an arc-shaped clamping plate 202. Four groups of arc-shaped clamping plates 202 are installed around the outer upper end of the porous filter barrel 201. The arc-shaped clamping plate 202 drives the porous filter barrel 201 to be positioned and connected with the tank body 1 through the arc-shaped clamping groove 102. The second separation barrel 302 is installed in the middle of the inner side of the third separation barrel 303. The first separation barrel 301 is installed in the middle of the inner side of the second separation barrel 302. The first separation barrel 301, the second separation barrel 302 and the third separation barrel 303 are all linearly surrounded by a plurality of circular holes for liquid to pass through. A rotating sleeve 305 is installed in the middle of the lower end of the third separation barrel 303. A rotating column 306 is provided inside the rotating sleeve 305, and a variable speed motor 307 is installed at the lower end of the rotating column 306.

[0026] When working, first open the circular sealing cover 103 by lifting the handle 104, then pick up the hole filter barrel 201, and the arc-shaped clamping plate 202 drives the hole filter barrel 201 to be positioned and connected with the tank body 1 through the arc-shaped clamping groove 102. After installation, lift the handle 104, and the circular sealing ring 106 drives the circular sealing cover 103 to fit and connect with the tank body 1 along the inner wall of the tank body 1, so that the circular sealing ring 106 can increase the sealing performance and prevent the water-oil mixture from being affected by the outside world during filtering and separation. Then, the water-oil mixture sample to be tested is passed through the liquid inlet pipe 105 and the connecting pipe 107 into the hole filter barrel 201 for preliminary filtration, so as to remove large particles in the water-oil mixture sample;

[0027] When the filtered water-oil mixture sample gradually and completely enters the first separation barrel 301, through the control of the display panel 101, the rotating column 306 drives the rotating sleeve 305 to rotate through the drive of the variable speed motor 307, so that the first separation barrel 301, the second separation barrel 302 and the third separation barrel 303 separate the oil and water through the centrifugal force generated by high-speed rotation. In this process, through the adjustment of the display panel 101, according to the operator's need for detection time, the variable speed motor 307 can continuously increase the rotation speed, so that the water-oil mixture sample passes through multiple stages of separation and reaches complete separation of water and oil, thereby accelerating the work process. Under the action of centrifugal force, the water in the water-oil mixture sample will move outward through the circular hole under the action of centrifugal force, while the oil with lower density is closer to the rotation center, thereby achieving the effect of water-oil separation. After the wastewater is discharged, the oil separated in the third separation barrel 303 is measured for oil content through electrochemical reaction through the action of the electrochemical sensor 304, and the detected value is reflected on the display panel 101 for easy observation and recording;

[0028] When the filtration and separation is completed, the telescopic valve 110 is slowly opened through the control of the display panel 101 and the electromagnetic control valve 111, and the separated waste water flows out through the outlet pipe 109 for unified treatment. During this process, the arc column 108 firmly supports the tank body 1.

[0029] Through the above steps, the controllable detection time means that the frequency and duration of the detection can be set as needed, which is particularly important for real-time monitoring of oil pollution in water bodies. By setting a reasonable detection time, it can ensure that changes in water quality are discovered in time, providing a scientific basis for taking corresponding treatment and protection measures. In addition, through the multi-stage separation of the first separation barrel 301, the second separation barrel 302 and the third separation barrel 303, and the variable speed motor 307 continuously accelerates the rotation speed, the water-oil mixture sample can be effectively separated completely, and then through the action of the electrochemical sensor 304, the oil separated in the third separation barrel 303 is measured by electrochemical reaction. The oil content data can be obtained in a short time, thereby improving work efficiency.
