The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] For examples, please refer to the attached Figure 1-4 A multi-stage filtering grinding fluid filter comprises a filtering water tank 1, a separation mechanism 2 is connected to one side of the top of the filtering water tank 1, and a fine filtering mechanism 3 is connected to the other side of the top of the filtering water tank 1;

[0025] The top of the filtered water tank 1 is provided with a first opening 11, a second opening 12 and a third opening 13 in sequence;

[0026] The separation mechanism 2 includes a plurality of mesh filter boxes 22 which are nested together in the upper and lower parts and are located in the second opening 12, a lower water tank 21 which is connected to the upper surface of the filtered water tank 1 and corresponds to the first opening 11, and a magnetic filter 23 which is connected to the top of the lower water tank 21. The water outlet position of the lower water tank 21 corresponds to the water inlet position of the mesh filter box 22.

[0027] For details, please refer to the attached Figure 3 and 4 The top of the filter-type filter box 22 is provided with an expanded outer edge 221 extending toward the opening direction of the box body, and the expanded outer edge 221 of the filter-type filter box 22 at the bottom layer abuts against the upper surface of the filtered water tank 1, and a gap is provided between adjacent filter-type filter boxes 22;

[0028] The magnetic filter 23 includes an upper water tank 231 connected to the upper surface of the lower water tank 21 and communicated with the lower water tank 21, and a scraping roller 232, a magnetic separation roller 233 and a guide plate 234 connected in sequence to one side of the top opening of the upper water tank 231;

[0029] A waste residue collection box 14 is provided on one side of the filter water tank 1, and the top opening position of the waste residue collection box 14 corresponds to the slag discharge end of the magnetic separation roller 233;

[0030] It should be noted that, in this embodiment, the expanded outer edge 221 at the top of the screen filter box 22 is overlapped at the second opening 12 at the top of the screen filter box 22 to complete the connection between the screen filter boxes 22 and the screen filter boxes 22, and the expansion outer edge 221 is set so that the adjacent expansion outer edges 221 overlap each other, so that multiple screen filter boxes 22 can be plugged into each other, so as to facilitate the connection between multiple screen filter boxes 22;

[0031] Furthermore, the upper water tank 231 provides support for the scraping roller 232, the magnetic separation roller 233 and the guide plate 234, and the magnetic separation roller 233 is driven to rotate by a motor, so that the rotating magnetic separation roller 233 is in contact with the grinding fluid in the upper water tank 231, so that the metal powder floating in the grinding fluid is adsorbed on the magnetic separation roller 233;

[0032] The scraping roller 232 blocks the metal powder adsorbed on the magnetic separation roller 233, so that the scraping roller 232 is used to separate the metal powder accumulated between the scraping roller 232 and the magnetic separation roller 233, so that the metal powder falls along the magnetic separation roller 233 onto the guide plate 234, and finally falls into the waste slag collection box 14 for collection under the guidance of the inclined guide plate 234, thereby completing the preliminary separation of the metal powder and the grinding fluid, and by collecting the powder, reducing the secondary contamination of the grinding fluid by the metal powder;

[0033] By setting the upper water tank 231 and the lower water tank 21, the flow rate is controlled through the through holes used for circulation between the upper water tank 231 and the lower water tank 21 to prevent the grinding fluid from entering the filter box 22 too quickly, thereby reserving time for magnetic separation filtration.

[0034] For details, please refer to the attached Figure 3 and 4The side of the lower water tank 21 away from the guide plate 234 is connected with an open pipe 211, and the end of the open pipe 211 away from the lower water tank 21 extends to the top of the filter box 22;

[0035] A thermostat 4 is provided between the separation mechanism 2 and the fine filtering mechanism 3, and the thermostat 4 is plugged into the interior of the third opening 13;

[0036] The fine filtering mechanism 3 includes a self-priming pump 31 connected to the upper surface of the end of the filtered water tank 1 away from the separation mechanism 2, the water inlet end of the self-priming pump 31 is connected to the filtered water tank 1, the water outlet end of the self-priming pump 31 is connected to a first fine filtering pressure tank 32, and a second fine filtering pressure tank 33 connected to the water outlet end of the first fine filtering pressure tank 32;

[0037] It should be noted that, in this embodiment, the grinding fluid that has been magnetically separated in the lower water tank 21 is discharged through the open pipe 211. Since one end of the open pipe 211 away from the lower water tank 21 extends to the top of the filter-type filter box 22, the grinding fluid enters the filter-type filter box 22 for multi-stage filtration.

[0038] Furthermore, the temperature in the filtered water tank 1 is controlled by a thermostat 4 to facilitate subsequent recycling of the grinding fluid;

[0039] Furthermore, the filtered grinding fluid in the filter water tank 1 is pumped out by the self-priming pump 31, and the grinding fluid is passed through the first fine filtration pressure tank 32 and the second fine filtration pressure tank 33 in sequence, so that the grinding fluid is filtered again by the first fine filtration pressure tank 32 and the second fine filtration pressure tank 33 to improve the filtration accuracy.

[0040] The specific operation mode of the utility model is as follows:

[0041] When filtering the grinding fluid, the grinding fluid to be filtered is injected into the upper water tank 231, and the magnetic separation roller 233 is driven to rotate by the motor, so that the metal powder floating in the grinding fluid is adsorbed on the magnetic separation roller 233 through the contact between the rotating magnetic separation roller 233 and the grinding fluid in the upper water tank 231, and the metal powder adsorbed on the magnetic separation roller 233 is blocked by the scraping roller 232, so that the metal powder accumulated between the scraping roller 232 and the magnetic separation roller 233 is separated by the scraping roller 232, so that the metal powder falls along the magnetic separation roller 233 to the guide plate 234, and finally falls into the waste slag collection box 14 for collection after being guided by the inclined guide plate 234, thereby completing the preliminary separation of the metal powder and the grinding fluid, and reducing the secondary contamination of the grinding fluid by the metal powder by the collection of the powder;

[0042] The grinding fluid that has been magnetically separated in the lower water tank 21 is discharged through the open pipe 211. Since one end of the open pipe 211 away from the lower water tank 21 extends to the top of the filter-type filter box 22, the grinding fluid enters the filter-type filter box 22 for multi-stage filtration.

[0043] The filtered grinding fluid in the filter water tank 1 is pumped out by the self-priming pump 31, and the grinding fluid is passed through the first fine filtration pressure tank 32 and the second fine filtration pressure tank 33 in sequence, so that the grinding fluid is filtered again by the first fine filtration pressure tank 32 and the second fine filtration pressure tank 33 to improve the filtration accuracy.

[0044] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
