Description

Technical Field

[0001] This utility model relates to the field of oil-water separator technology, and in particular to an oil-water separator suitable for chip discharge oil. Background Technology

[0002] In industries such as machining, the treatment of chip removal fluid has always been a critical and challenging issue. Chip removal fluid contains a mixture of oil and water, and if not effectively treated, it will not only cause serious environmental pollution but also lead to resource waste. The traditional gravity sedimentation separation method is often used, which relies solely on the density difference between oil and water, allowing the oil-water mixture to settle in a large sedimentation tank, where the oil naturally floats to the top and the water naturally sinks, thus achieving preliminary separation.

[0003] An oil-water separator, authorized under publication number CN213294903U, includes a frame, a solid-liquid separation device, and a solid-liquid separation chamber, an oil-water separation chamber, and a purified water chamber mounted on the frame. The solid-liquid separation chamber has an inlet, and the solid-liquid separation device is connected to the chamber and capable of separating the food waste input from the inlet. The oil-water separation chamber has an oil-distribution pipe and a water-distribution pipe. The lower part of the oil-distribution pipe connects to the upper part of the oil-water separation chamber, and an oil drain pipe is connected to the oil-distribution pipe. The lower part of the water-distribution pipe extends into and connects to the lower part of the oil-water separation chamber. The oil-water separation chamber is connected to the solid-liquid separation chamber, and an auxiliary separation device is connected to the oil-water separation chamber to promote oil-water stratification. A first connecting pipe is connected to the water-distribution pipe, and the highest liquid point of the oil drain pipe is higher than the highest liquid point of the first connecting pipe. This invention has a simple and reasonable structure and can achieve good separation and treatment of food waste.

[0004] Regarding the aforementioned technologies, the existing oil-water separators have significant shortcomings in feed control, failing to automatically adjust according to the capacity of the oil-water mixture within the separator, often resulting in overload of the separator and severely affecting the oil-water separation effect. Therefore, this utility model provides an oil-water separator suitable for chip discharge oil. Utility Model Content

[0005] The purpose of this application is to provide an oil-water separator suitable for chip removal oil, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] An oil-water separator for chip removal includes a separation chamber. A feed pipe is fixedly connected to the top of the separation chamber. A sealing assembly is installed inside the feed pipe. The sealing assembly includes a blocking column disposed inside the feed pipe. A limiting groove is formed on the inner side wall of the feed pipe. A sliding plate is fixedly connected to the side wall of the blocking column, and the sliding plate slides within the limiting groove. A movable rod is fixedly connected to one end of the blocking column. A rotating shaft is fixedly connected to the side wall of the movable rod. A connecting rod is fixedly connected to the side wall of the rotating shaft. A floating disc is hinged to one end of the connecting rod.

[0008] The bottom wall of the separation chamber is fixedly connected to a limiting cylinder, and the limiting cylinder has holes on its surface. The floating disc slides inside the limiting cylinder, and the connecting rod slides on the side wall of the limiting cylinder.

[0009] A fixing frame is fixedly connected to the side wall of the separation chamber, and a motor is fixedly connected to the side wall of the fixing frame.

[0010] A fixing block is fixedly connected to the inner side wall of the fixing frame, and a first rotating rod is rotatably connected inside the fixing block. The first rotating rod passes through the fixing frame and the fixing block, and the output end of the motor is fixedly connected to one end of the first rotating rod.

[0011] The inner sidewall of the separation chamber is rotatably connected to a second rotating rod, and a scraper is fixedly connected to the sidewall of the second rotating rod. The second rotating rod passes through the separation chamber, and one end of the first rotating rod and one end of the second rotating rod are provided with the same track.

[0012] The side wall of the separation chamber is fixedly connected to a communicating oil outlet pipe, and the side wall of the first rotating rod is fixedly connected to a connecting block. One end of the connecting block is rotatably connected to a linkage rod, and one end of the linkage rod is hinged to a movable plug. The movable plug slides inside the oil outlet pipe.

[0013] The bottom of the oil outlet pipe is fixedly connected to a connecting guide pipe, one end of the guide pipe is fixedly connected to a connecting collection chamber, and a collection cabinet is slidably connected inside the collection chamber.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] By using a sealing component, when the oil-water mixture in the separation chamber reaches a certain volume, the feed pipe can be blocked to stop the feed from continuing. The combination of the feed pipe, blocking column, limiting groove, sliding plate, connecting plate, rotating shaft, connecting rod and floating plate achieves the necessary settling time for oil-water separation, allowing the oil layer and water layer to fully separate. After the feed pipe is blocked, the oil-water mixture in the separation chamber will not be agitated by the entry of new material, ensuring that oil droplets have enough time to rise to the surface and form a stable oil layer, and the water layer can also settle to the bottom, making the separation more thorough.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" 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 a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1: Reference Figure 1-4 The oil-water separator shown includes a separation chamber 1 for containing an oil-water mixture and providing space for oil-water separation. A feed pipe 2 is fixedly connected to the top of the separation chamber 1, introducing the oil into the separation chamber 1. A sealing assembly is installed inside the feed pipe 2, including a blocking column 14 disposed inside the feed pipe 2. The blocking column 14 is used to block the feed pipe 2 when necessary, preventing further oil entry. A limiting groove 12 is formed on the inner side wall of the feed pipe 2, limiting the movement of the blocking column 14 and ensuring that the blocking column 14 can only move in a specific direction within the feed pipe 2. A sliding plate 13 is fixedly connected to the side wall of the blocking column 14, sliding within the limiting groove 12. The cooperation between the sliding plate 13 and the limiting groove 12 ensures the stability of the movement of the blocking column 14. A movable rod 15 is fixedly connected to one end of the blocking column 14. The movable rod 15 is used to transmit external force and drive the blocking column 14 to move. A rotating shaft 16 is fixedly connected to the side wall of the movable rod 15. The rotating shaft 16 acts as a lever fulcrum, changing the direction of force transmission so that the movement of the connecting rod 17 can effectively drive the movable rod 15 and the blocking column 14. A connecting rod 17 is fixedly connected to the side wall of the rotating shaft 16. The connecting rod 17 transmits the movement of the floating disk 18 to the rotating shaft 16, thereby driving the movable rod 15 and the blocking column 14. A floating disk 18 is hinged to one end of the connecting rod 17. The floating disk 18 can rise with the rise of the liquid level in the separation chamber 1, using buoyancy to generate power, and pushes the blocking column 14 to block the feed pipe 2 through the connecting rod 17, the rotating shaft 16, and the movable rod 15.

[0025] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a limiting cylinder 19 is fixedly connected to the inner bottom wall of the separation chamber 1. The limiting cylinder 19 is used to restrict the movement trajectory of the floating disk 18, allowing it to slide only in the vertical direction. Holes on the surface of the limiting cylinder 19 allow the liquid in the separation chamber 1 to freely enter and exit the limiting cylinder 19, ensuring that the floating disk 18 can rise and fall normally according to changes in liquid level. The floating disk 18 slides inside the limiting cylinder 19, moving up and down by sensing changes in the buoyancy of the liquid in the separation chamber 1, thereby driving the connected rod 17 to move. The connecting rod 17 slides along the side wall of the limiting cylinder 19, moving along the side wall of the limiting cylinder 19 under the influence of the floating disk 18, transmitting the vertical movement of the floating disk 18 to the rotating shaft 16. A fixing frame 4 is fixedly connected to the side wall of the separation chamber 1. The fixing frame 4 supports and fixes the motor 8 and the fixing block 9, ensuring the stability of the related components during installation. A motor 8 is fixedly connected to the side wall of the fixed frame 4. The motor 8 serves as a power source, providing power for the subsequent mechanical operation of the entire oil-water separator and driving the first rotating rod 5 to rotate. A fixed block 9 is fixedly connected to the inner side wall of the fixed frame 4. The fixed block 9 supports and positions the first rotating rod 5, allowing it to rotate stably within the fixed block 9. The first rotating rod 5 is rotatably connected inside the fixed block 9. Driven by the motor 8, the first rotating rod 5 rotates, driving the track 10 to rotate and the connecting block 20 to rotate, thus transmitting power. The first rotating rod 5 passes through the fixed frame 4 and the fixed block 9, realizing the transmission of power between different components. The output end of the motor 8 is fixedly connected to one end of the first rotating rod 5, directly transmitting the power of the motor 8 to the first rotating rod 5, causing it to rotate. A second rotating rod 24 is rotatably connected to the inner side wall of the separation chamber 1. The second rotating rod 24 provides rotational support for the scraper 11, enabling it to rotate within the separation chamber 1. A scraper 11 is fixedly connected to the side wall of the second rotating rod 24. The scraper 11 rotates under the drive of the second rotating rod 24, scraping the upper layer of oil in the separation chamber 1 towards the oil outlet pipe 3, assisting in the discharge of the oil. The second rotating rod 24 passes through the separation chamber 1, connecting to the first rotating rod 5 via a track 10, thereby receiving power from the first rotating rod 5. One end of the first rotating rod 5 and one end of the second rotating rod 24 are provided with the same track 10, which acts as a transmission, transmitting the rotation of the first rotating rod 5 to the second rotating rod 24, causing them to rotate synchronously. An oil outlet pipe 3 is fixedly connected to the side wall of the separation chamber 1, used to discharge the separated oil from the separation chamber 1 and transport it to a subsequent collection device. A connecting block 20 is fixedly connected to the side wall of the first rotating rod 5, used to connect the first rotating rod 5 and the linkage rod 21, converting the rotation of the first rotating rod 5 into the oscillation of the linkage rod 21. One end of the connecting block 20 is rotatably connected to the linkage rod 21. The linkage rod 21 swings under the drive of the connecting block 20, converting the circular motion of the first rotating rod 5 into linear reciprocating motion.One end of the linkage rod 21 is hinged to a movable plug 23. The swinging motion of the linkage rod 21 drives the movable plug 23 to reciprocate within the oil outlet pipe 3. The movable plug 23 slides inside the oil outlet pipe 3, and this reciprocating sliding prevents blockages in the oil outlet pipe 3, ensuring smooth oil discharge. A connecting guide pipe 22 is fixedly connected to the bottom of the oil outlet pipe 3. The guide pipe 22 guides the oil discharged from the oil outlet pipe 3 to the collection chamber 6, changing the direction of oil flow. One end of the guide pipe 22 is fixedly connected to the connecting collection chamber 6. The collection chamber 6 is used to collect the oil separated from the separation chamber 1 and transported through the oil outlet pipe 3 and the guide pipe 22. A collection cabinet 7 is slidably connected inside the collection chamber 6. The collection cabinet 7 facilitates the storage and transfer of the oil in the collection chamber 6 for subsequent processing.

[0026] The working principle of this practical device is as follows: When using this device, the oil-water mixture is first introduced into the separation chamber 1 through the feed pipe 2. When the storage volume of the separation chamber 1 reaches a certain level, the buoyancy of the liquid entering the limiting cylinder 19 will cause the floating plate 18 to rise. The connecting rod 17 causes the rotating shaft 16 to deflect, which in turn causes the moving rod 15 to push the blocking column 14 into the interior of the feed pipe 2, thus blocking the feed pipe 2 and stopping the feeding. After standing for a period of time, the motor 8 is started after the oil layer and water are separated. The motor 8 drives the first rotating rod 5 to rotate, which causes the scraper 11 to rotate through the track 10, allowing the oil layer to enter the oil outlet pipe 3 and fall into the collection chamber 6 for collection through the guide pipe 22. At the same time as the first rotating rod 5 rotates, the fixed block 9 rotates synchronously. The linkage rod 21 will drive the movable plug 23 to reciprocate in the oil outlet pipe 3 to prevent the oil outlet pipe 3 from being blocked.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
