Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical industry, in particular to a petrochemical oil-water separation device. Background Art

[0002] After searching the patent document with the publication number of CN220478197U, this patent document utilizes the principle of communicating vessels to separate oil and water through the liquid level difference in two boxes. The mixed liquid is injected into the first box. When the liquid covers the floating block, the floating block drives the piston connected to it to move upward, so that the water at the lower end of the mixed liquid flows into the second box through the connecting pipe. When the liquid level of the water in the second box is higher than the oil outlet pipe, the oil at the upper end of the mixed liquid in the first box flows out from the oil outlet pipe, and the floating plate in the second box also moves upward, so that the water flows out from the water outlet pipe;

[0003] When this patent document separates oil and water, since the mixed liquid contains impurities, when the water flows into the connecting pipe, the impurities will cause blockage in the connecting pipe, making the water flow out slowly, and it is difficult to clean the impurities accumulated in the connecting pipe. When all the mixed liquid enters the first box, due to the decreasing liquid level, the remaining mixed liquid in the box may be difficult to discharge. Content of the Utility Model

[0025] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0026] The present utility model will be further described below with reference to the accompanying drawings:

[0027] As Figures 1-7 shown, a petrochemical oil-water separation device includes a chassis 1. Inside the chassis 1, there is a separation barrel 2 for separating the mixed liquid. Behind the separation barrel 2, there is an oil storage barrel 3. On one side of the separation barrel 2, there is a water storage barrel 4. It also includes a filtering mechanism 5 for filtering impurities and a lifting mechanism 6 for pushing the mixed liquid to rise.

[0028] In this embodiment: The separation barrel 2 is fixedly connected to the water storage barrel 4 through a water outlet pipe. The connection position of the water outlet pipe and the separation barrel 2 is higher than the connection position of the oil outlet pipe and the separation barrel 2. The top of the separation barrel 2 is fixedly connected with a conveying pipe. At the connection position of the oil outlet pipe and the separation barrel 2, there is a PTFE polytetrafluoroethylene microporous filter membrane for oil-water separation. When the oil-water mixture precipitates, the oil first flows out of the separation barrel 2. Since one end of the oil outlet pipe is provided with a PTFE polytetrafluoroethylene microporous filter membrane for separating oil and water, when the water rises, it flows into the water outlet pipe and will not flow out from the oil outlet.

[0029] In this embodiment: The lifting mechanism 6 includes a lifting plate 602 which is slidably connected inside the separation barrel 2. Below the lifting plate 602, there is a cylinder 601, and the telescopic part of the cylinder 601 is fixedly connected to the bottom of the lifting plate 602. Above the lifting plate 602, there is a rotating shaft 604 which penetrates through the top end of the separation barrel 2. The outer part of the rotating shaft 604 is provided with a spiral groove. The lower end of the rotating shaft 604 is fixedly connected with a rotating plate 603 for stirring impurities in water. The rotating shaft 604 is located at the central position of the top end of the separation barrel 2. The conveying pipe is behind the rotating shaft 604. The lower end of the rotating shaft 604 is located between the oil outlet pipe and the water outlet pipe. At the bottom of the rotating shaft 604, there are balls for rotating on the top of the lifting plate 602. A rubber sealing ring for preventing the mixed liquid from flowing out is fixed on the outside of the lifting plate 602. At the position of the rotating shaft 604 on the separation barrel 2, there are guide columns for its rotation. When the oil-water mixture precipitates, the cylinder 601 pushes the lifting plate 602 to move upward, so that the oil flows out from the oil outlet pipe. The lifting plate 602 continues to move upward. When the lifting plate 602 touches the balls at the bottom of the rotating shaft 604, since the rotating shaft 604 is threadedly connected to the top of the separation barrel 2, the balls rotate on the top of the lifting plate 602, and the rotation of the rotating shaft 604 drives the rotating plate 603 to rotate. While rotating, the rotating shaft 604 drives the rotating plate 603 to rise with the lifting plate 602, stirring the impurities and water, so that the impurities and water flow out from the water outlet pipe together.

[0030] In this embodiment: The chassis 1 is provided with four L-shaped brackets arranged in a circular pattern. The upper ends of the four L-shaped brackets are all fixedly connected to the separation barrel 2. A fixing seat for supporting the cylinder 601 is fixedly connected between the four L-shaped brackets. By fixing the separation barrel 2 and the cylinder 601 through the chassis 1, the process of the oil-water mixture standing and precipitating is made stable.

[0031] In this embodiment: The filtering mechanism 5 includes a filtering box 501 which is located above the water storage barrel 4. Inside the filtering box 501, there is a filtering slot 502 which is slidably connected. The bottom of the filtering slot 502 is provided with evenly distributed filtering holes. The filtering box 501 is located at the middle position of the water outlet pipe. On one side of the filtering slot 502 away from the separation barrel 2, there is a semi-circular ring for pulling out the filtering slot 502. The flowing out impurities and water flow into the filtering box 501. Since the bottom of the filtering slot 502 in the filtering box 501 is provided with evenly distributed filtering holes, the water flows out of the filtering slot 502, and the impurities remain in the filtering slot 502. When the water has drained, the filtering slot 502 is pulled out through the semi-circular ring behind the filtering slot 502 to dispose of the impurities.

[0032] Working principle: The oil-water mixture is flowed into the separation barrel 2 through the delivery pipe. After precipitation for a period of time, the air cylinder 601 pushes the lifting plate 602 to move upward, so that the upper-layer oil flows into the oil storage barrel 3 through the oil outlet pipe. The lifting plate 602 continues to move upward. Since the end of the oil outlet pipe is provided with a PTFE polytetrafluoroethylene microporous membrane for separating oil and water, water will not flow out from the oil outlet pipe. When the lifting plate 602 abuts against the ball at the bottom of the rotating shaft 604, the lifting plate 602 continues to rise and drives the rotating shaft 604 to rise. Since the rotating shaft 604 and the separation barrel 2 are connected by means of a spiral groove and a guide post in cooperation, the rotating shaft 604 spirally rises, driving the rotating plate 603 to rotate, stirring the water and impurities, so that the water and impurities both flow into the filter tank 502 in the filter box 501 through the water outlet pipe. Since the bottom of the filter tank 502 is provided with uniform filter holes, the water flows out from the filter tank 502 into the water storage barrel 4, and the impurities remain in the filter tank 502. After the separation is completed, the filter tank 502 is pulled out through the semi-circular ring at the rear end of the filter tank 502 to process the impurities.

[0033] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
