Description

Oil water separation device

This creation relates to a water-and-water separation device, and more particularly to a device for separating oil and moisture from a waste liquid in a cutting operation.

According to the CNC automatic processing machine, the workpiece is sprayed with lubricating oil and cutting fluid during the cutting operation to achieve the purpose of lubrication and cooling. The lubricating oil and the cutting fluid are mixed together after being sprayed, and can be separated by a separating device. The two are separated and recovered through a recovery unit for recycling.

Conventional oil-water separation devices mostly use physical properties of oil-water immiscible and separation of properties such as density and viscosity. However, after a certain period of use, the cutting fluid will deteriorate due to contact with high-temperature tools or special metal workpieces, so that the cutting fluid is acidic and the viscosity is increased, and then combined with the lubricating oil, so that some are only separated by a single method or relatively simple. The separator of the separation method is difficult to separate, and the separated result still contains too much cutting fluid, which causes the consumption of the cutting fluid during the CNC machining process to be excessively large and often needs to be replenished, resulting in an increase in cost. Although replacing the deteriorated cutting fluid is the most fundamental solution, in fact, based on cost considerations, this is still not the top priority.

In view of this, how to improve the above problems is the primary issue that the creative office wants to solve.

The main purpose of the present invention is to provide a water-water separation device that utilizes a difference in physical properties between oil and water to perform a multi-stage oil-water separation process for the recovery waste liquid of the cutting operation to highly separate the waste oil from the cutting fluid.

In an embodiment, a second support is disposed in the second chamber of the separation tank, and a support seat is disposed below the second mesh belt, and the height is not lower than the drain. The support seat described above is provided with a plurality of perforations.

In an embodiment, the second guiding plate has a top surface for receiving the waste liquid and a bottom surface opposite to the top surface, and the top surface can guide the waste liquid to the second chamber of the separating groove; The second guiding plate is provided with a plurality of small through holes penetrating from the top surface to the bottom surface, the through holes are for the oil in the waste liquid to pass through; the outlet opening is disposed on the bottom surface of the second guiding plate.

The above objects and advantages of the present invention are not to be understood in detail from the detailed description and the accompanying drawings.

The oil and water referred to in this specification refer to the lubricating oil and cutting fluid used in the machining of the CNC automatic processing machine. Please refer to FIG. 1 , which shows the oil-water separation device provided by the present invention, which is disposed on a recovery tank 6 for containing waste water mixed with oil and water. The oil-water separation device has a base 1 and a driving shaft 11 connected and driven by a motor 12; wherein the driving shaft 11 has a first driving section 111 and a second driving section. 112, the first driving section 111 is wound with a first mesh belt 2, and the second driving section 112 is wound with a second mesh belt 3, and the two mesh belts 2, 3 are respectively driven by corresponding The segments 111, 112 are driven to scroll.

The first mesh belt 2 is suspended downwardly and extends into the recovery tank 6 and immersed in the waste liquid to allow the waste liquid to adhere to the mesh structure and can be rolled with the first mesh belt 2 And was taken up. At this time, since the oil and water have differences in viscosity, the oil having a higher viscosity is more likely to adhere to the first mesh belt 2 than the water having a lower viscosity; on the other hand, in the process of drawing upward, the viscosity The lower water is also easily removed, so the oil that is extracted from it will have more oil than the water, thus forming the first stage of oil-water separation.

The pedestal 1 is provided with a separation groove 4 corresponding to the first mesh belt 2 and the second mesh belt 3. As shown in FIG. 2, the separation groove 4 has an accommodating space, and an internal partition 43 is disposed therein to divide the space inside the groove into a first chamber 41 and a second chamber 42. The bottom end is not connected to the bottom of the separation tank 4, and thus a communication port 44 is formed to allow the first chamber 41 to communicate with the second chamber 42. In addition, a drain port 45 is disposed on the wall surface of the first chamber 41, and is disposed at a position higher than the communication port 44. Furthermore, the separation groove 4 is provided with a first guide plate 46 located below the first mesh belt 2 and connected to the separation groove 4 in an inclined manner, and the lower end is guided to the second volume. Room 42.

With the above configuration, as shown in FIG. 3, when the waste liquid drawn by the first mesh belt is dropped by its own weight, it is received by the first guide 46 and introduced into the second chamber 42. Due to the difference in density between the oil and the water, the waste liquid immediately forms a separation phenomenon of oil and water when entering the second chamber 42, wherein the water is located in the lower layer L1 and the oil is located in the upper layer L2. The water flowing in the lower layer L1 can flow to the first chamber 41 via the communication port 44, and the water surface of the first chamber 41 and the second chamber 42 are approximately equal in height, waiting for water. When the plane reaches the drain 45, it can be discharged from the drain 45; and because the drain 45 is located higher than the communication port 44, the water level plane is higher than the communication port 44, and the lower layer L1 The water forms an obstruction to close the communication port 44, so that the oil of the upper layer L2 cannot flow to the first chamber 41 via the communication port 44, thereby forming oil and water separation in the second stage.

The second mesh belt 3 is suspended from the driving shaft and extends into the second chamber 42. The second mesh strip 3 is only immersed in the previously separated upper layer L2, allowing oil to adhere to its mesh structure and being drawn up as it is rolled. Further, in this embodiment, the second chamber 42 is located below the second mesh belt 3 and is provided with a support seat 47 having a plurality of perforations 471 for the passage of waste liquid, which has a support plane. 472, wherein the height of the support plane 472 is not lower than the drain port 45, thereby ensuring that the support plane 472 is located above the interface of oil and water; in other words, it is ensured that the waste liquid located on the support plane 472 belongs to the upper layer L2. . Accordingly, the second mesh belt 3 does not extend downward beyond the support plane 472 to ensure that the waste liquid it draws belongs to the upper layer L2. In the same manner as the oil and water separation in the first stage described above, among the waste liquids taken by the second mesh belt 3, the oil and water are separated again due to the difference in viscosity, and the third stage oil and water are formed. Separation.

Then, as shown in FIG. 1, the separation groove 4 is provided with a second guide plate 48 extending obliquely in the second mesh belt 3, and can receive the second mesh shape due to its own weight. With 3 drops of waste liquid. As shown in FIG. 4 , the second guide plate 48 defines a top surface 481 and a bottom surface 482 , wherein the top surface 481 is configured to receive waste liquid and can be guided to the second chamber 42 of the separation slot 4 . The bottom surface 482 is located on the opposite side of the top surface 481 and is connected to a lead-out port 484. The second guide plate 48 is provided with a plurality of small through holes 483 extending from the top surface 481 to the bottom surface 482, and the through holes 483 can pass oil in the waste liquid. With the above structure, the oil-water separation in the fourth stage can be formed by utilizing the difference in viscosity between the oil and the water; in detail, when the waste liquid falls to the second guide 48, the water having a lower viscosity is more Will not adhere to the top surface 481, will quickly slide down the top surface 481 and introduce the second chamber 42 without penetrating through the through hole 483 to the bottom surface 482; on the other hand, the viscosity is better than The high oil is easily attached to the top surface 481, and thus has a longer time for it to penetrate the through hole 483 and flow to the bottom surface 482, and is introduced along the bottom surface 482 into the outlet 484, as shown in FIG. It is discharged into a collection tank 5 as shown.

Through the above description, the creation utilizes the difference in viscosity and density of oil and water, and can carry out a four-stage separation process for the waste liquid, and each of the separation stages can achieve the effect of removing moisture, so that the proportion of oil in the obtained result is obtained. It will gradually increase; in other words, the creation can retain more water in the recovery tank 6 for subsequent recycling and reuse, thereby reducing the consumption of cutting fluid, thereby achieving the purpose of reducing costs.

However, the above description of the embodiments is merely illustrative of the present invention and is not intended to limit the present invention. Therefore, the replacement of equivalent elements should still be within the scope of the present invention.

In summary, it can be made clear to the skilled person that the creation can achieve the aforementioned objectives, and it has already met the requirements of the Patent Law and submitted an application according to law.
