Description

Technical Field

[0001] This utility model relates to the field of cutting fluid treatment technology, specifically to a cutting fluid separation and transfer device. Background Technology

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate cutting tools and workpieces. It is composed of a variety of high-performance additives through scientific compounding, and has good cooling, lubrication, rust prevention, degreasing and cleaning, anti-corrosion, and easy dilution properties. After use, cutting fluid contains a large amount of iron filings and chemical reagents. If the iron filings are not separated and used directly, it will damage the machinery. Therefore, it is necessary to separate and transfer the cutting fluid.

[0003] A search revealed a Chinese patent (publication number: CN207790777U) that discloses "a cutting fluid separation and transfer device, comprising a seat, a box and a chip processing box welded to the upper surface of the seat, a support rod and a liquid outlet pipe fixedly connected to one outer surface of the box, with the liquid outlet pipe located below the support rod, a rotating shaft rotatably connected to the outer surface of the support rod, a cover plate rotatably connected to the outer wall of the rotating shaft, the cover plate located on the upper surface of the box, a liquid inlet provided on the upper surface of the cover plate, a fixing member welded to the outer surface of the cover plate away from the rotating shaft, a fixing block and a drain pipe welded to the other outer surface of the box, with the drain pipe located below the fixing block, the fixing member located inside the fixing block, a rivet penetrating the outer surface of the fixing block, and a filter screen provided inside the box."

[0004] However, in the process of implementing the relevant technology, the above-mentioned patent has certain technical defects. In particular, the patent mainly uses a filter screen to separate iron filings from the cutting fluid. However, the filtered iron filings will accumulate on the top surface of the filter screen. As the amount of iron filings accumulates, the filter screen pores are easily blocked, which makes it impossible to achieve subsequent separation work. This separation method requires the filter screen to be frequently removed for cleaning or replacement, which not only increases the amount of manual labor, but also affects the separation efficiency of the cutting fluid. In view of this, this utility model proposes a cutting fluid separation and transfer device. Utility Model Content

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0031] like Figures 1-3As shown, this embodiment proposes a cutting fluid separation and transfer device, including a housing 2, a storage tank 1 connected to the bottom of the housing 2, an inlet pipe 3 for introducing cutting fluid fixedly connected to one end of the housing 2, a filter screen 4 snapped into the top of the inner side of the storage tank 1, a drain pipe 6 fixedly connected to the bottom of the storage tank 1, a cleaning mechanism 5 provided inside the housing 2, the cleaning mechanism 5 including a movable seat 53, a translation component provided inside the housing 2, the translation component including a reciprocating screw 51 rotatably connected to the inner side of the housing 2, a guide rod 52 fixedly connected to one end inside the housing 2 and arranged parallel to the reciprocating screw 51, and one end of the movable seat 53 being connected to the reciprocating screw 51. The lead screw 51 is threaded, and the other end of the movable seat 53 is slidably connected to the guide rod 52. A motor 54 is fixedly installed on the outside of the housing 2. The output shaft of the motor 54 is fixedly connected to the reciprocating lead screw 51. A slide rod 55 is slidably connected through the middle of the movable seat 53. An electromagnet 56 is fixedly connected to the bottom of the slide rod 55. A guide 57 is provided at the top of the slide rod 55 to drive the electromagnet 56 to periodically descend or rise by cooperating with the movement of the movable seat 53. A lifting plate 58 is fixedly connected to one end of the inner side of the housing 2. A dust suction component 50 is provided at one end of the lifting plate 58 to suck up iron filings when the electromagnet 56 is raised.

[0032] Cutting fluid is introduced through the inlet pipe 3, and filter screen 4 separates the iron filings from the cutting fluid. The filtered cutting fluid flows into the storage tank 1 for storage. Then, the motor 54 is started to drive the reciprocating screw 51 to rotate, causing the movable seat 53 to move back and forth along the axis of the reciprocating screw 51. This causes the electromagnet 56 to move back and forth above the filter screen 4 along with the movable seat 53. When the electromagnet 56 is energized, it can attract the iron filings accumulated on the filter screen 4 to clean it. Then, the electromagnet 56 is lifted so that the dust suction component 50 can suck out the iron filings. The whole process can realize the automatic cleaning of the filter screen 4, which can not only avoid the problem of filter screen 4 clogging, but also reduce the frequency of disassembly and cleaning of the filter screen 4, effectively reducing the amount of manual labor.

[0033] Furthermore, such as Figure 4 As shown, the electromagnet 56 includes a mounting box 561 fixedly connected to the bottom of the slide bar 55. An iron core 562 is fixedly connected to the inner side of the mounting box 561. A coil 563 is wrapped around the outer side of the iron core 562. The bottom width of the iron core 562 is the same as the width of the filter screen 4. The iron core 562 can contact the top surface of the filter screen 4 by descending.

[0034] By energizing the coil 563, the iron core 562 becomes magnetic, causing the bottom surface of the iron core 562 to contact the filter screen 4 and adsorb the iron filings accumulated on the filter screen 4. At the same time, the reciprocating movement of the iron core 562 in conjunction with the movable seat 53 achieves dynamic cleaning of the filter screen 4, greatly improving the cleaning effect of the filter screen 4 and avoiding the problem of filter screen 4 pore clogging.

[0035] Furthermore, such as Figure 5 As shown, the guide member 57 includes a mounting base 571 fixedly connected to the top of the slide rod 55. A roller 572 is rotatably connected to the inner side of the mounting base 571. A guide rail 573 that slides and engages with the roller 572 is fixedly connected to the top of the inner side of the housing 2. The guide rail 573 has a front-convex and rear-concave structure. A return spring 574 is sleeved on the slide rod 55. The top of the return spring 574 abuts against the mounting base 571, and the bottom of the return spring 574 abuts against the movable seat 53. The length of the convex part of the guide rail 573 is the same as the length of the filter screen 4, and the length of the concave part of the guide rail 573 is the same as the length of the guide rail 573. The connection between the convex part and the concave part of the guide rail 573 is an arc surface structure.

[0036] By starting the motor 54, the reciprocating screw 51 is driven to rotate, causing the movable seat 53 to reciprocate along the axis of the reciprocating screw 51. This causes the slide rod 55 to drive the roller 572 to roll along the guide rail 573. When the roller 572 rolls on the protrusion of the guide rail 573, the slide rod 55 moves downward, causing the electromagnet 56 to descend and contact the top surface of the filter screen 4. At this time, the return spring 574 is compressed and accumulates potential energy, causing the electromagnet 56 to move along the top surface of the filter screen 4 to dynamically clean the iron filings. When the roller 572 rolls on the concave part of the guide rail 573, the return spring 574 releases potential energy, causing the slide rod 55 to move upward and the electromagnet 56 to rise. At this time, the electromagnet 56 rises above the lifting plate 58, and the dust suction component 50 sucks out the iron filings attracted by the electromagnet 56, thus realizing the automatic cleaning of iron filings.

[0037] Furthermore, such as Figure 6 As shown, the dust collection component 50 includes a suction fan 501 fixedly installed on the outside of the housing 2. The inlet end of the suction fan 501 communicates with the inside of the housing 2. The outlet end of the suction fan 501 is fixedly connected to a duct 502. The outlet end of the duct 502 is fixedly connected to a collection box 503. The collection box 503 is located on the outer wall of the housing 2. A filter screen 504 is fixedly connected to the inner side of the collection box 503. An exhaust pipe 505 is fixedly connected to the bottom of the collection box 503.

[0038] By activating the suction fan 501, the iron filings inside the suction fan 501 can be sucked out. Then, the iron filings are guided into the collection box 503 through the air guide pipe 502. Under the filtration of the filter screen 504, the iron filings accumulate in the collection box 503, thus realizing the collection of iron filings, which facilitates subsequent centralized recycling and processing.

[0039] Furthermore, such as Figure 7As shown, a roller brush 59 is provided at the top of the raised plate 58. The roller brush 59 includes a sleeve 591 rotatably connected to the inner side of the housing 2. A brush cylinder 592 is fixedly connected to the middle of the sleeve 591. One end of the sleeve 591 is rotatably connected to the outlet end of the exhaust pipe 505, and the sleeve 591 is connected to the exhaust pipe 505. Several evenly distributed air holes 593 are opened on the outer wall of the brush cylinder 592.

[0040] After the electromagnet 56 is raised above the lifting plate 58, it moves to contact the brush cylinder 592, causing the brush cylinder 592 to remove iron filings from the bottom of the electromagnet 56. At the same time, the exhaust pipe 505 introduces gas into the sleeve 591, and then sprays it out through the air hole 593 on the outer wall of the brush cylinder 592, causing the air hole 593 to spray airflow towards the bottom of the electromagnet 56 for rinsing, further improving the cleaning effect on the electromagnet 56.

[0041] Furthermore, such as Figure 8 , Figure 9 As shown, a pressure sensor 511 is fixedly connected to one end of the top of the electromagnet 56. When the electromagnet 56 is raised, the pressure sensor 511 abuts against the movable seat 53. A controller is fixedly connected to the outside of the housing 2. The controller includes a microcontroller (a conventional model in the prior art, such as PIC16F877A) that is connected to the pressure sensor 511. The circuit switch of the electromagnet 56 and the suction fan 501 is electrically connected to the microcontroller. Figure 9 In the diagram, M1 is motor 54, S1 is the main circuit switch, M2 is suction fan 501, and S2 is the circuit switch between electromagnet 56 and suction fan 501.

[0042] Working principle: First, the cutting fluid is introduced through the inlet pipe 3, and the iron filings in the cutting fluid are filtered and separated by the filter screen 4. The filtered cutting fluid flows into the storage tank 1 for storage.

[0043] During cleaning, turn on the main circuit switch S1 to power on the motor 54 and drive the reciprocating screw 51 to rotate. At the same time, control S2 connects the circuit with the electromagnet 56, so the electromagnet 56 is energized and magnetized. When the reciprocating screw 51 rotates, the movable seat 53 moves back and forth along the axis of the reciprocating screw 51. At this time, the roller 572 rolls on the protrusion of the guide rail 573, and the slide bar 55 moves downward, causing the electromagnet 56 to descend and contact the top surface of the filter screen 4. At this time, the return spring 574 is compressed and accumulates potential energy, so the electromagnet 56 moves back and forth above the filter screen 4 with the movable seat 53. When the electromagnet 56 is energized, it can attract the iron filings accumulated on the filter screen 4 to achieve dynamic cleaning of the filter screen 4.

[0044] When roller 572 moves to the recess of guide rail 573, return spring 574 releases potential energy, causing slide bar 55 to move upward and electromagnet 56 to rise. At this time, electromagnet 56 rises above lifting plate 58, and pressure sensor 511 abuts against movable seat 53. At this time, the circuit of microcontroller control S2 and suction fan 501 is connected, electromagnet 56 is de-energized, causing iron filings on electromagnet 56 to fall onto lifting plate 58. Suction fan 501 can suck up the fallen iron filings and guide them into collection box 503 through air duct 502 for collection. The accumulated movement of electromagnet 56 will abut against brush cylinder 592, causing brush cylinder 592 to remove the iron filings that have not fallen off the bottom of electromagnet 56. At the same time, exhaust pipe 505 directs air to sleeve 591. Gas is introduced internally and then ejected through the air holes 593 on the outer wall of the brush cylinder 592, causing the air holes 593 to spray airflow towards the bottom of the electromagnet 56 for rinsing, further improving the cleaning effect on the electromagnet 56. This ensures that the iron filings on the electromagnet 56 are completely cleaned and can be completely sucked out by the suction fan 501. When the roller 572 moves to the protrusion of the guide rail 573 again, the pressure sensor 511 disengages from the movable seat 53, the microcontroller control S2 connects the circuit with the electromagnet 56, the suction fan 501 stops, and the filter screen 4 is cleaned again. The whole process realizes the automatic cleaning of the filter screen 4 and iron filings, which not only solves the problem of filter screen 4 clogging, but also realizes the automatic start and stop of the suction fan 501 through intelligent control, which greatly saves energy consumption.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
