Description

Technical Field

[0001] The utility model relates to the technical field of cutting fluid recovery, in particular to a filtering device for cutting fluid. Background Art

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate tools and workpieces. Cutting fluid is composed of a variety of super-functional additives through scientific compounding, and at the same time has good cooling performance, lubricating performance, rust prevention performance, oil removal and cleaning function, anti-corrosion function, and easy dilution characteristics. It overcomes the problems of traditional soap-based emulsions such as being prone to odor in summer, difficult to dilute in winter, and poor rust prevention effect, and has no adverse effect on lathe paint. It is suitable for cutting and grinding of ferrous metals and is the most advanced grinding product at present. All indicators of cutting fluid are superior to those of saponified oil. It has good cooling, cleaning, rust prevention and other characteristics, and also has the characteristics of being non-toxic, odorless, non-corrosive to the human body, non-corrosive to equipment, and non-polluting to the environment.

[0003] The prior art such as the cutting fluid recovery device disclosed in the publication number: CN220783527U relates to the field of cutting fluid recovery. The cutting fluid recovery device includes a movable recovery box and a recovery box inserted inside the recovery box. A detachable filter screen is provided at the top of the recovery box, and a clamping mechanism is provided on the front side of the filter screen. The clamping mechanism includes clamping rods inserted into the inner sides of both sides of the filter screen and a spring disposed between the two groups of clamping rods. The ends of the clamping rods are movably inserted into the side wall of the recovery box. In this cutting fluid recovery device, the recovery box is placed below the cleaning frame to be cleaned. When the cut workpiece is placed inside the cleaning frame, the cutting fluid on the surface of the workpiece drips downward, passes through the filter screen and enters the recovery box, and is finally stored through the recovery box. After the processing is completed, the recovery box is moved to the recovery point through the universal wheels, and then the recovery box is pulled out to recover the cutting fluid inside, avoiding polluting the ground and wasting at the same time.

[0004] In view of the above and related prior arts, the inventor believes that the following defects often exist: This cutting fluid recovery device only filters iron filings and impurities in the cutting fluid through a single group of filter screens. However, in the process of metal cutting, the iron filings and impurities may be large or small. Filtering with a single group of filter screens or relying solely on the filter screen may result in unsatisfactory filtering effect, so that there are still a large amount of iron filings in the cutting fluid after filtering and recovery. In the subsequent use process, it is easy to affect the metal cutting process. Summary of the Utility Model

[0005] In view of the fact that the existing cutting fluid recycling device only filters the iron filings impurities in the cutting fluid through a set of filter meshes, however, during the metal cutting process, the iron filings impurities may vary in size. Filtering with a single set of filter meshes or relying solely on the filter meshes may result in an unsatisfactory filtering effect, so that there are still a large amount of iron filings in the recycled cutting fluid after filtration. During subsequent use, it is likely to affect the metal cutting process. Therefore, the present utility model is proposed.

[0006] Therefore, the purpose of the present utility model is to provide a filtering device for cutting fluid, and its purpose lies in: by providing a first filter mesh, larger iron filings in the cutting fluid can be filtered. The cutting fluid filtered by the first filter mesh flows towards the second filter mesh through the diversion of the inclined plate. Through the filtration of the second filter mesh, smaller iron filings can be intercepted in the accumulation bin. The cutting fluid passing through the second filter mesh can absorb even tinier iron filings through a magnet again. After the filtration is completed, the filtering component can be lifted upwards to clean the iron filings on the filter mesh. Through the cooperation of two sets of filter meshes and the absorption of the magnet, the problem that filtering with a single set of filter meshes or relying solely on the filter meshes may lead to an unsatisfactory filtering effect is solved.

[0036] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manner of the present utility model with reference to the accompanying drawings of the specification.

[0037] Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0038] Embodiment 1

[0039] Refer to Figures 1-10 , which is the first embodiment of the present utility model, provides a filtering device for cutting fluid, including a filtering box 1 and bases 2 arranged at the four corners of the lower end of the filtering box 1. It is characterized in that: a filtering assembly 3 is arranged in the inner cavity of the filtering box 1, a rotating assembly 7 is arranged on one side of the filtering assembly 3 in the inner cavity of the filtering box 1, an absorbing assembly 8 is arranged on the outer wall of the rotating assembly 7, a solenoid valve 9 is arranged on one outer wall of the filtering box 1, and a motor 10 is arranged at the lower end of the rotating assembly 7;

[0040] The filtering assembly 3 includes a mounting plate 31 arranged between the inner walls at both ends of the filtering box 1, a first filter screen 32 is arranged at the upper end of the mounting plate 31, a second filter screen 33 is fixedly inserted at the upper end of the mounting plate 31, an inclined plate 34 is arranged at the lower end of the first filter screen 32, and a stacking bin 35 is arranged between the lower end of the inclined plate 34 and the outer wall of the second filter screen 33. The first filter screen 32 is located above the inclined plate 34. A stacking bin 35 is formed among the first filter screen 32, the second filter screen 33 and the inclined plate 34.

[0041] Installation grooves 4 are opened on both sides and the bottom surface in the middle of the inner wall of the filtering box 1. The outer wall of the mounting plate 31 is movably inserted into the installation grooves 4, and a sealing gasket 5 matching with the mounting plate 31 is arranged between the installation grooves 4.

[0042] Two symmetrical groups of first plug rods 6 are arranged at the bottom end of the installation groove 4 . The filter assembly 3 also includes two groups of first slots 36 opened on the inner wall of the lower end of the installation plate 31 . The first plug rods 6 are movably inserted in the first slots 36 .

[0043] The cutting fluid to be recovered and filtered is poured into the upper end of the first filter screen 32. After being screened by the first filter screen 32, larger iron chips are intercepted at the upper end of the first filter screen 32. Smaller iron chips pass through the first filter screen 32 along with the cutting fluid, and then are guided by the inclined plate 34 and hit the second filter screen 33. Under the screening of the second filter screen 33, smaller iron chips are intercepted at the outer end of the second filter screen 33 and are accumulated in the accumulation bin 35. When there are too many iron chips on the filter screen, which affects the filtering speed of the cutting fluid, the mounting plate 31 is lifted up, and the mounting plate 31 slides upward along the mounting groove 4, so that the first insertion rod 6 leaves the first slot 36, and the two sets of filters are connected. The filter assembly 3 is taken out together with the net, and the filter assembly 3 is turned over. The iron filings attached to the upper end of the filter are cleaned by shaking and flushing, etc. After the cleaning, the filter assembly 3 is installed to the upper end of the installation groove 4 by aligning the first slot 36 with the first plug rod 6 and sliding the mounting plate 31 downward along the installation groove 4 from top to bottom. A sealing gasket 5 that matches the mounting plate 31 is arranged between the installation grooves 4. The arrangement of the sealing gasket 5 increases the sealing of the contact surface between the installation groove 4 and the mounting plate 31. The two sets of filter nets cooperate with the absorption of the magnet to solve the problem that a single set of filter nets or filtering only by the filter net may result in an unsatisfactory filtering effect.

[0044] Example 2

[0045] Reference Figures 1-10 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the rotating assembly 7 includes two groups of rotating rods 71 rotatably arranged on the lower end surface of the filter box 1, and the outer wall of the rotating rod 71 is provided with two symmetrical groups of second plug rods 72, and the upper end of the rotating rod 71 is provided with a bolt 73. The outer wall of the rotating rod 71 is sleeved with a sleeve rod 74, and the inner wall of the sleeve rod 74 is provided with a second slot 75 matched with the second plug rod 72, and the second plug rod 72 can be movably inserted in the second slot 75. The upper end of the sleeve rod 74 is provided with a connecting hole 76, and the upper end of the bolt 73 passes through the connecting hole 76. The outer wall of the bolt 73 located on the upper end surface of the sleeve rod 74 is threadedly sleeved with a nut 77;

[0046] The absorption assembly 8 includes a plurality of mutually symmetrical fixed plates 81 arranged on the outer wall of the sleeve rod 74, and an insert block 82 is movably inserted at the lower end of the fixed plate 81, and a magnet 83 is fixedly connected to one end of the insert block 82, and a stopper 84 is arranged at the upper end of the insert block 82;

[0047] At the upper end of the fixing plate 81, there are two groups of symmetric fixing blocks 85. Between the two groups of fixing blocks 85, there is a slide bar 86. A spring 87 is sleeved on the outer wall of the slide bar 86. A baffle 88 is movably sleeved on the outer wall of the slide bar 86. The upper end of the spring 87 is fixedly connected to one of the fixing blocks 85, the lower end of the spring 87 is fixedly connected to the baffle 88, and the lower end of the baffle 88 abuts against the end of the stopper 84 away from the fixing plate 81.

[0048] The lower end of the rotating rod 71 movably passes through the bottom end of the filter box 1 and is fixedly connected to the output end of the motor 10.

[0049] When the cutting fluid with finer iron filings passing through the second filter screen 33 enters the space formed by the filter box 1 and the mounting plate 31, start the motor 10 to rotate slowly. The motor 10 drives the rotating rod 71 to rotate. The rotating rod 71 drives the sleeve rod 74 to rotate through the cooperation of the second insertion rod 72 and the second insertion slot 75. The sleeve rod 74 drives the fixing plate 81 to rotate, thereby driving the insertion block 82 and the magnet 83 to rotate. The magnet 83 slowly rotates to absorb the finer iron filings in the cutting fluid and adheres them to the upper end of the magnet 83. When the number of iron filings absorbed on the upper end of the magnet 83 no longer increases, turn off the motor 10, rotate the nut 77, remove the nut 77, lift the sleeve rod 74 upward. The sleeve rod 74 slides along the second insertion rod 72 arranged on the outer wall of the rotating rod 71 through the second insertion slot 75, and take out the sleeve rod 74. Then lift the baffle 88 upward. The baffle 88 slides along the slide bar 86 and compresses the spring 87. When the baffle 88 leaves the stopper 84, the magnet 83 can be pulled out outward to clean the iron filings on the outer wall of the magnet 83. After cleaning, insert the magnet 83 into the fixing plate 81 through the insertion block 82 until the stopper 84 contacts the fixing plate 81 and cannot move further. Release the spring 87. Under the elastic force of the spring 87, the baffle 88 slides downward along the slide bar 86 until the lower end of the baffle 88 contacts the upper end of the insertion block 82 to complete the locking of the insertion block 82. Then along the connection hole 76 opened at the upper end of the sleeve rod 74, the bolt 73 passes through the connection hole 76, and the second insertion slot 75 is aligned with the second insertion rod 72. Sleeve the sleeve rod 74 on the outer wall of the rotating rod 71. Then rotate the nut 77 until the nut 77 contacts the upper end face of the sleeve rod 74 and cannot rotate further, thereby completing the installation of the sleeve rod 74 and further completing the cleaning of the magnet 83.

[0050] The rest of the structure is the same as that of Embodiment 1.
