Abstract
Description
Technical Field
[0001] The utility model relates to chemical equipment, in particular to waste lubricating oil dehydration equipment. Background Art
[0002] During lubricating oil use, combustion generates water. Due to its high density, lubricating oil can accumulate water, causing it to emulsify and gradually lose its lubricating properties. Waste lubricating oil often contains a high water content, typically reaching 6% or even 12%. Therefore, the waste lubricating oil hydrogenation process requires water removal during the pretreatment stage. Water is also generated during the hydrogenation process, making it essential to remove moisture from the oil. Therefore, testing the water content in the oil is also crucial.
[0003] Currently, the petrochemical industry uses two common methods for dehydrating oil products: solvent extraction and heating evaporation. While solvent extraction offers high accuracy, it is complex, time-consuming, and uses highly toxic solvents, leading to potential contamination. While heating evaporation is simple and time-efficient, it is less accurate and generates significant vapor pollution during the heating process. Therefore, a dehydrator with improved accuracy, minimal pollution, and a shorter timeframe is proposed, which simplifies the process, reduces pollution, and is easy to use. Summary of the Invention
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the background technology and provide a waste lubricating oil dehydrator with low pollution, simple operation and high accuracy.
[0005] The technical solution of the utility model is as follows: a new waste lubricating oil dehydrator comprises a metal housing body 1, a centrifugal water separation container 2, a manual valve 3, a discharge port 4, an anti-slip support steel frame 5, a liquid level observation port 6, a numerical control panel 7, a covered feed port 8, a power switch 9, a centrifugal speed and time display screen 10, a centrifugal speed increase button 11, a centrifugal speed decrease button 12, and a time control button 13. The metal housing body 1 is fixed by the anti-slip support steel frame 5.
[0006] The centrifugal water separation container 2 is inside the metal shell body 1 .
[0007] The manual valve 3 and the discharge port 4 are located at the center of the lower shell of the metal shell body 1 , and the manual valve 3 is installed on the pipeline of the discharge port 4 .
[0008] The anti-skid support steel frame 5 is located at the four edges of the lower shell of the metal shell body 1 and has an appearance of a metal cylinder with a fixed plate at the bottom.
[0009] The liquid level observation port 6 is located at the lower left portion of the surface of the metal shell body 1 and is in the shape of an elongated strip made of transparent glass.
[0010] The numerical control panel 7 is located in the upper left part of the metal shell body 1, and includes a power switch 9 that can control the start and stop of the dehydrator, a centrifugal speed and time display screen 10, and a centrifugal speed increase button 11, a centrifugal speed decrease button 12 and a time control button 13 for adjusting the operating parameters of the centrifugal water separation container 2.
[0011] The covered feed port 8 is located at the upper portion of the metal shell body 1 and has an appearance of a circular hole with a cover.
[0012] The specific technical solution of the dehydrator is that the main body of the metal shell is made of special steel with high corrosion resistance and hardness, and a centrifugal water separation container that can perform high-speed centrifugal operation is placed inside. Open the lid of the covered feed port, add the waste lubricating oil sample that needs to be dehydrated, close the lid, and start the dehydrator through the power switch on the CNC panel. According to the density of the waste lubricating oil sample, the centrifugal time and speed of the waste lubricating oil sample in the centrifugal water separation container are selected. Click the centrifugal speed increase button and the time control button, and the centrifugal water separation container starts working. The waste lubricating oil can be separated from the water by high-speed centrifugation in the centrifugal water separation container. The anti-slip support steel frame can effectively prevent the dehydrator from sliding during operation. Click the centrifugal speed reduction button to reduce the speed of the centrifugal water separation container to no longer rotate. The separation situation can be observed through the liquid level observation port made of special glass. After achieving the expected goal, the power switch on the CNC panel can be turned off, the manual valve is opened, and the water is drained through the discharge port. After the removed water is drained, the dehydrated waste lubricating oil can be collected.
[0013] When it is necessary to remove water from a dense lubricating oil sample, open the covered feed port 8, add the dense waste lubricating oil sample, turn on the power switch 9 on the numerical control panel 7, click the centrifugal speed increase button 11 to set the high-speed centrifugal speed, click the time control button 13 to set the long centrifugal time, and the specific data will be displayed on the centrifugal speed and time display 10. Wait for the machine to start. After the waste lubricating oil stops centrifuging in the centrifugal water separation container 2, observe the separation of the waste lubricating oil and water through the liquid level observation port 6, open the manual valve 3, and drain the water in the lower layer of the centrifugal water separation container 2 through the discharge port 4. Close the manual valve 3, wipe the discharge port 4 dry, and then open the manual valve 3 again to collect the dehydrated dense waste lubricating oil through the discharge port 4.
[0014] When it is necessary to remove water from a low-density lubricating oil sample, open the covered feed port 8, add the low-density waste lubricating oil sample, turn on the power switch 9 on the numerical control panel 7, click the centrifugal speed increase button 11 to set the low-speed centrifugation speed, click the time control button 13 to set the short centrifugation time, and the specific data will be displayed on the centrifugal speed and time display 10. Wait for the machine to start. After the waste lubricating oil stops centrifuging in the centrifugal water separation container 2, observe the separation of the waste lubricating oil and water through the liquid level observation port 6, open the manual valve 3, and drain the water in the lower layer of the centrifugal water separation container 2 through the discharge port 4. Close the manual valve 3, wipe the discharge port 4 dry, and then open the manual valve 3 again to collect the dehydrated low-density waste lubricating oil through the discharge port 4.
[0015] The advantages of this waste lubricating oil dehydrator are: a CNC panel controls the operating time and speed of the centrifugal water separation container. Centrifugal force causes water droplets in the waste lubricating oil to aggregate in the lower layer of the oil sample. The separation process can be monitored through a liquid level observation port, allowing for rapid separation of water from the waste lubricating oil, achieving effective dehydration. This dehydrator is widely applicable in the lubricating oil industry. BRIEF DESCRIPTION OF THE DRAWINGS
