Detailed ways

With reference to the accompanying drawings of the present utility model, a technical solution of the embodiment of the present utility model is further elaborated.

Embodiment one:

Referring to FIG. 1, a liquid purification device includes a motor 10, an adsorption device, a cleaning device 30, and a separation device 40. The adsorption device includes a pie-shaped magnetic disk 20 with a magnetic surface, and the driving device is connected to the magnetic disk. 20 The center of the circle is connected to drive the disk to rotate along the center of the circle; the cleaning device 30 includes a scraper 31 and a guide groove 32, the guide groove is arranged obliquely in the radial direction of the disk 20, and one end of the scraper 31 is tightly closed. It is attached to the round side of the magnetic disk, and the other end is placed in the guide groove 32; the separation device 40 includes a separation box 41 and an oil receiving box 42, and the separation box 41 is close to the magnetic disk 20 and placed in the Below the guide groove 32 , the oil receiving box 42 is in close contact with the separation box 41 . The guide groove 32 is set as a U-shaped groove with one end open, and the open end is set away from the center of the disk 20 at the lower end and placed on the separation box 41 . When the magnetic disk 20 is rotated by the motor 10, the magnetic disk is immersed in the liquid, so the oil slick and iron filings in the liquid will be adsorbed on the magnetic disk, and will be scraped into the guide groove 32 when it rotates to the scraper 31. The flow grooves are arranged obliquely and the center of the disk is high, so due to the action of gravity, oil slicks and iron filings (hereinafter collectively referred to as mixtures) will flow into the separation box 41 from the guide grooves. It should be noted that a plurality of magnetic disks 20 can be provided as required, and scrapers and guide grooves can be respectively provided on both sides of the magnetic disk 20 .

As shown in FIG. 2 , the surface of the magnetic disk 20 is coated with a layer of adsorption material, such as silicon dioxide. A non-magnetic sector region 21 and a magnetic sector region 22 are provided along the center of the circle. The iron scraps are collected at the scraper 31 under the adsorption action of the magnetic disk 20 , and when the scraper 31 rotates to the non-magnetic area 21 , the scraper 31 can scrape the scraps into the guide groove.

As shown in FIG. 1 and FIG. 3 , the separation box 41 includes a casing 411, a mixing area 412, a solid-liquid separation plate 413, a dirty oil area 414, an oil discharge port 415, an oil-water separation plate 416, a water discharge port 417, In the water purification zone 418 , the solid partition plate 413 is connected with the casing 411 on three sides, and the cavity formed in the middle is the mixing zone 412 . And the highest surface of the solid-liquid separation plate is lower than the top surface of the casing 411 . One side of the solid-liquid separating plate 413 is provided with an oil-water separating plate 416 in parallel. The oil discharge port 415 is disposed in the dirty liquid area 414 formed by the solid-liquid separation plate 413 and the oil-water separation plate 416 , and is connected through one side of the outer wall of the housing 411 . A clean liquid area 418 is formed between the oil-water separation plate 416 and the casing 411 , and the drain port 417 is arranged in the clean liquid area. And the height of the oil discharge port 415 is higher than that of the water discharge port 417 . The debris-liquid mixture flows from the diversion groove 32 to the mixing area 412 of the separation box 41 and gradually accumulates. After the liquid is filled, the liquid enters the dirty oil area 414 through the solid-liquid separating plate 413, and the solid precipitates. A gap is left between the oil-water separating plate 416 and the bottom of the casing 411 as an oil-water sedimentation channel. As the liquid gradually accumulates over the height of the oil-water channel, only the water flows through the channel into the clean liquid zone 418 because the oil is less dense than water (the small amount carried by the disk), and the oil floats on the liquid surface. When the amount of water reaches the height of the drain port 417 , the water flows back to the designated position through the drain port, and the oil continues to accumulate.

Embodiment 2:

Referring to FIG. 4 and FIG. 5 , the liquid purification device 70 is installed on the cover plate 50 and then placed on the water tank 60 as a whole. At this time, the magnetic disk 20 in the liquid purification device is immersed in the liquid of the water tank. Start the motor 10, the disk 20 starts to rotate and continuously absorbs the metal chips suspended in the water tank. When the disk rotates to the liquid level, some impurities such as sludge floating in the liquid will be adsorbed on the surface of the metal chips, and some of them will be adsorbed on the surface of the disk without metal chips. .

When the magnetic disk continues to rotate to the scraper 31 , the scraper 31 scrapes metal chips, sludge, etc. into the guide groove 32 . It should be noted that the metal chips need to be rotated to the scraper by the non-magnetic area 21 of the magnetic disk 20 before being scraped off to the guide groove.

The guide groove 32 has an inclined angle, which will lead the solid-liquid mixture such as metal chips and sludge into the separation box 41 under the action of gravity. The solid-liquid mixture gradually accumulates in the mixing area 412 of the separation box 41. When the liquid height reaches the solid-liquid separation partition 413, the liquid continuously overflows into the oil-water separation environment. The oil-water separation partition 416 has a certain gap with the bottom of the shell 411, After the liquid passes through this gap, the oil can only be in the dirty oil area 414 due to the action of gravity, while the water carried by the magnetic disk 20 can pass through the gap between the oil-water separation separator 416 and the bottom of the casing 411 due to the action of equal pressure. flow. When the water gradually accumulates and reaches the height of the drain port 417 , the water directly returns to the water tank through the drain port 417 . Since the oil discharge port 415 is slightly higher than the water discharge port 417 , the floating oil floats on the water. When the oil accumulation height reaches the oil discharge port 415 , the oil enters the oil receiving box 42 through the oil discharge port 415 .

It should be noted that arranging the liquid purification device around the water tank pump can effectively reduce the suction of metal chips by the pump, reduce the blockage of the cooling nozzle of the machine tool and the blockage of the pump. The magnetic disk of the device is coated with lipophilic and hydrophobic silica adsorption material, which not only improves the adsorption rate of oil slick but also reduces the water carrying capacity. The separation box is equipped with two layers of separation plates, which can effectively separate metal chips, oil and water. The device can be used as an oil-water separation device in a non-magnetic metal chip environment, and can be used as a magnetic separation device and an oil-water separation device in a magnetic metal chip environment, with a large scope of application and small limitations.
