[0029] In some preferred embodiments, the modified liquid filter assembly includes a steel ball filter screen 16, a liquid accumulation baffle 17, a magnetic filter assembly and other impurity filter assemblies arranged in sequence from top to bottom.

[0030] In some preferred embodiments, the magnetic suction filtration assembly includes: an iron chip pool 18, an electromagnet 19 and a support frame 20. The iron chip pool 18 is arranged at the bottom of the liquid baffle 17, and an iron chip guide pipe 25 and a limiting groove 26 are arranged at the bottom of the iron chip pool 18. There are several support frames 20, which are evenly distributed at the bottom of the iron chip pool 18, and the support frames 20 are adapted to the limiting groove 26. The side wall of the second tank body 7 is provided with an iron chip discharge port 8, which is connected to the iron chip guide pipe 25, and the electromagnet 19 is installed inside the iron chip pool 18. The number of support frames 20 can be 4, 6 or 8.

[0031] like Figure 2 As shown, in some preferred embodiments, an atmospheric communication port 27 is provided at the bottom of the iron chip pool 18, and the atmospheric communication port 27 is located on the second tank body 7 and symmetrically distributed with the iron chip discharge port 8, so that the air pressure inside the tank body assembly is connected with the external air pressure.

[0032] In some preferred embodiments, the grinding liquid concentration preparation component includes: a motor 13, a motor support plate 15, a stirring blade 24, a preparation liquid inlet 9 and a discharge port 11, the preparation liquid inlet and the discharge port 11 are respectively arranged on the bottom cover 10, the main shaft of the motor 13 is connected to the stirring blade 24, the stirring blade 24 is located inside the bottom cover 10, the motor 13 is placed on the motor support plate 15, and the motor support plate 15 is erected between the support feet 12.

[0033] In some preferred embodiments, a concentration detector 23 is further included. The concentration detector 23 is disposed inside the bottom cover 10 and is located adjacent to the discharge port 11 .

[0034] The working principle of the present invention is:

[0035] The initial state is that the feed port 1 is open, the air pressurization port 2 is closed, the cleaning liquid feed port 3 is closed, the steel ball discharge port 5 is closed, and the electromagnet 19 is energized. At this time, the abrasive enters the device through the feed port 1, and the atmosphere connection port 27 is opened. After a period of time, the steel ball filter layer is filled with a certain amount of abrasive, and a part of the strengthening and modification liquid flows through the steel ball filter screen 16 due to gravity, but some liquid is still adsorbed on the steel balls, especially the part where the steel balls contact each other, which adsorbs a large amount of liquid. At this time, the feed port 1 is closed, the air pressurization port 2 is opened, and the high-pressure air enters the steel ball filter layer through the air pressurization port 2, forming an airflow from top to bottom in the first tank body 6, causing the abrasive liquid adsorbed on the steel balls to separate from the steel balls along with the high-pressure airflow and flow through the steel ball filter screen 16 into the liquid accumulation baffle 17.

[0036] like Figure 2 As shown, the grinding liquid gathers on the liquid accumulation baffle 17 and flows from its lower mouth to the top cone of the iron filing pool 18. At this time, the grinding liquid contains small iron filings and solid particulate impurities such as grinding powder collided by the enhanced modified grinding process. In the process of the grinding liquid flowing from the top cone of the iron filing pool 18 to the bottom, the iron filing pool 18 is in the shape of a cone, which can better evenly divert the grinding liquid at the top to the side of the cone, so that the iron filings contained in the grinding liquid are evenly attracted by the magnetic attraction of the electromagnet 19 inside the iron filing pool 18, and then closely adhere to the side of the cone of the iron filing pool 18 and flow to the bottom of the pool with the grinding liquid until the iron filing pool 18 is filled with grinding liquid. The iron filings are precipitated at the bottom of the iron filing pool 18 by the magnetic attraction. In addition, the top of the outer edge of the iron filing pool 18 is inclined inward, which can better prevent the iron filings from flowing out of the iron filing pool 18 with the washing of the grinding liquid. The iron filing pool 18 is in the shape of a bow.

[0037] The grinding liquid containing other solid particulate impurities overflows from the iron filings pool 18 and flows to the semiconductor microfiltration inorganic membrane 21. After preliminary microfiltration, it flows to the semiconductor ultrafiltration inorganic membrane 22 for further ultrafiltration. The air pressure above the semiconductor microfiltration inorganic membrane 21 is higher than the pressure below. At the same time, the air pressure above the semiconductor ultrafiltration inorganic membrane 22 is higher than the pressure below, which also speeds up the filtration rate.

[0038] Since then, the grinding liquid filtered by the semiconductor ultrafiltration inorganic membrane 22 has been almost pure, but due to changes in the environment during the processing, transportation and filtration processes, the solvent in the prepared grinding liquid partially evaporates or is absorbed, resulting in an increase in the concentration of the grinding liquid, which requires further preparation.

[0039] pass Figure 2 The concentration detector 23 detects the concentration of the grinding liquid, and then the concentration is adjusted through the mixing liquid feed port 9, and the mixing is evenly mixed by the stirring blades 24. Finally, the prepared strengthening and modified liquid is discharged from the discharge port 11, completing the purification and filtration cycle of the entire strengthening and modified liquid.

[0040] The concentration detector 23 is close to the discharge port 11, so that it can accurately check whether the concentration of the discharged enhanced modified liquid meets the standard. If it does not meet the standard, the discharge port 24 is closed and the preparation liquid feed port 9 is opened to continue preparation.

[0041] When the equipment is cleaned after working for a period of time, the feed port 1 is closed, the air pressurization port 2 is opened, the cleaning liquid feed port 3 is opened, the steel ball discharge port 5 is closed, the iron chip discharge port 8 is opened, the electromagnet 19 is powered off, and the iron chips lose their magnetic attraction. At this time, the cleaning liquid flowing in will take the iron chips in the iron chip pool 18 away from the iron chip guide pipe 25 to the iron chip discharge port, completing the cleaning of the device.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
