Description
Technical Field
[0001] This utility model relates to the field of filtration and separation equipment, and in particular to a solid-water-oil three-phase separation device. Background Technology
[0002] With the continuous development of industrial production and the advancement of technology, the demand for efficient and environmentally friendly production processes is increasing. Especially in the metal processing industry, cutting fluid, as a crucial auxiliary material, plays a vital role in cooling, lubrication, and rust prevention. However, the machining process generates a large amount of metal shavings, abrasive chips, and other impurities. These impurities, when mixed with the cutting fluid, cause a decline in its performance, significantly reducing machining quality and efficiency, shortening its service life, increasing maintenance costs, and posing potential threats to the environment and the health of operators.
[0003] Traditional cutting fluid treatment methods mainly focus on removing solid particles, while neglecting the removal of high-viscosity oil or grease on machine tools. The presence of grease causes instantaneous slippage between the workpiece and the tool, and also accelerates the deterioration and foul odor of water-based cutting fluid.
[0004] While existing separation technologies can address these problems to some extent, or at least one of them, their application in practical production is limited by factors such as low separation efficiency, high energy consumption, or complex operation. Therefore, this project develops a novel three-phase separation system, aiming to provide a highly efficient, energy-saving, easy-to-operate solution adaptable to various operating conditions.

Detailed Implementation
[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings.
[0032] Example 1:
[0033] See appendix Figures 1-7 The solid-water-oil three-phase separation device shown in this utility model includes a liquid storage tank, in which a slow flow zone 100, a separation zone 200 and a reflux zone 300 are arranged in sequence and connected in sequence. A partition 400 is arranged between the slow flow zone 100, the separation zone 200 and the reflux zone 300 for separation.
[0034] In this embodiment, a dirty liquid inlet 101 is provided on the slow flow zone 100, and an inclined plate 102 is provided at the bottom. The inclined plate 102 is inclined from high to low in the same direction as the flow direction of the liquid in the slow flow zone 100, which is conducive to the rapid sliding of solid particles in the cutting fluid along the inclined plate 102.
[0035] In this embodiment, a partition 400 is provided between the slow flow zone 100 and the separation zone 200. A slow flow plate 401 is provided on the partition 400 to connect the slow flow zone 100 and the separation zone 200. At the same time, the slow flow plate 401 is tilted from the slow flow zone 100 toward the separation zone 200 to prevent the water flow from the outlet end of the slow flow zone 100 from being too large, thus playing a buffering role.
[0036] In this embodiment, an oil baffle 210 and an oil removal mechanism 220 are provided on the separation zone 200. The oil baffle 210 is located on the liquid outlet side of the separation zone 200, suspended above the liquid surface. Both ends of the oil baffle 210 are fixedly connected to the partitions 400 at both ends of the separation zone 200. The oil baffle 210 has a beveled structure along the liquid flow direction for collecting floating oil on the liquid surface. The oil removal mechanism 220 includes a power mechanism, a track 221, an oil outlet 222, and an oil collection box 223. The power mechanism drives the track 221 to rotate. The track 221 is partially submerged in the separation zone 200. The top of the track 221 is provided with an oil drain port 222, and the bottom of the oil drain port 222 is provided with an oil collection box 223. Driven by the power mechanism, the track 221 continuously picks up floating oil from the angled structure of the oil baffle plate 210 and transports it to the oil drain port 222 at the top of the track 221. The floating oil is separated from the track 221 under the action of gravity and flows into the oil collection box 223 through the oil drain port 222. Through the setting of the oil baffle plate 210 and the oil removal mechanism 220, the oil and water in the cutting fluid are separated.
[0037] In this embodiment, a partition 400 is also provided between the separation zone 200 and the return zone 300. An overflow port 402 is provided on the partition 400. The overflow port 402 is higher than the lower end face of the oil baffle 210 and lower than the upper end face of the oil baffle 210, so that the cutting fluid that has been degreased in the separation zone 200 can enter the return zone 300 through the overflow port 402 and flow out through the clean fluid outlet 301 of the return zone 300.
[0038] In this embodiment, a slag scraping mechanism 500 is also included. The slag scraping mechanism 500 is connected to the slow-flow zone 100 and the separation zone 200 of the storage tank, and is isolated from the reflux zone 300. The slag scraping mechanism 500 includes a drive motor 501, a scraper 502, a track belt 503, a track groove 504, and a slag discharge port 505. The drive motor 501 is connected to a drive shaft 506. Track grooves 504, which descend from high to low, are provided at both ends of the drive shaft 506. A track belt 503 is provided in the track groove 504. One end of the belt 503 is connected to a drive shaft 506, and the other end is connected to a driven shaft 507. Multiple scrapers 502 are arranged between the track belts 503. After the solid particles that settle in the liquid storage tank settle to the inner bottom surface of the scraping mechanism 500, when the scraper 502 moves to the bottom of the scraping mechanism 500 and makes full contact with the inner bottom surface of the scraping mechanism 500, the solid particles are displaced under the push of the scraper 502. When they move up to the slag discharge port 505 at the high point of the track groove 504, the solid particles fall and are discharged.
[0039] Example 2:
[0040] See appendix Figure 8-9In this embodiment, a vortex plate 600 is provided at the dirty liquid inlet 101 of the slow flow zone 100. The vortex plate 600 has a semi-circular arc structure, with one end connected to the side wall of the liquid storage tank and the other end not connected to the side wall of the liquid storage tank. The vortex plate 600 and the side wall of the liquid storage tank form an inverted frustum-shaped closed structure with a large upper opening and a small lower opening. A vortex port 601 is provided on the inclined plate 102 directly opposite the bottom opening of the vortex plate 600. The cutting fluid entering the slow flow zone 100 through the dirty liquid inlet 101 flows into the vortex plate 600. By forming a strong vortex in the vortex plate 600, the collision probability of solid particles in the cutting fluid is increased, which accelerates the aggregation and settling speed of solid particles. At the same time, the vortex helps to drive lighter solid particles towards the center and heavier particles towards the edge, improving the separation efficiency. Compared with the traditional gravity settling method, vortex settling can complete the separation process in a shorter time, which is especially important for application scenarios that require rapid processing of large amounts of cutting fluid.
[0041] Example 3:
[0042] See appendix Figure 8 and 10 In this embodiment, the separation zone 200 is filled with a honeycomb inclined plate 700. The upper end of the honeycomb inclined plate 700 is lower than the overflow port 402. The honeycomb inclined plate 700 is composed of multiple honeycomb-shaped inclined tube units 701, which are closely arranged at an inclination angle of about 60°. This guides the cutting fluid to flow from the lower end of the separation zone 200 upwards and into the separation zone 200. This design can divide the water flow into multiple small streams, slow down the water flow speed, and promote the sedimentation of solid particles.
[0043] The inclined structure of the inclined tube unit 701 effectively increases the settling path and time of particles. Compared with horizontal settling, the inclined design of the inclined tube unit 701 shortens the settling distance, making it easier for particles to settle to the bottom, thereby improving separation efficiency. At the same time, the small channels of the inclined tube unit 701 make the cutting fluid more uniform, facilitating the formation of a laminar flow. In a laminar flow state, particles are more likely to sink along the direction of the cutting fluid without being carried away by turbulence, thus improving settling efficiency.
[0044] When solid particles settle in the inclined tube, they gradually gather and slide down the wall of the inclined tube unit 701, eventually converging at the bottom. At this point, the solid and liquid are effectively separated, the solid particles settle, and the liquid flows from the upper part of the inclined tube unit 701 into the separation zone 200.
[0045] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
