Description

Technical Field

[0002] When using a five-axis CNC machine tool, appropriate cooling oil is required to cool the corresponding parts. To reduce the impact of metal shavings adhering to the cooling oil on subsequent coolant circulation, a corresponding negative pressure chip-liquid separation and filtration device is needed to treat them. Referring to the negative pressure chip separation mechanism disclosed in CN209565888U, it includes: a machine housing, a coolant recovery component, a metal shavings isolation component, and a negative pressure air supply component. The coolant recovery component includes a liquid collection tank, which can complete the separation of coolant and metal shavings during machine tool processing. It has the characteristics of simple operation, convenient use, and wide applicability. As described in the above patent, when using existing negative pressure chip-liquid separation and filtration devices, most devices cannot clear and discharge solid impurities retained in the filter element while the chip-liquid separation step is uninterrupted. Moreover, the few devices that can discharge solid impurities retained at the filter end are prone to causing coolant to be discharged through the solid impurity discharge end during the chip-liquid separation process, thereby causing coolant leakage and affecting the coolant recovery rate.

[0015] This invention also discloses a method for using a negative pressure chip-liquid separation and filtration device based on a five-axis linkage CNC machine tool, specifically including the following steps:

[0016] Step 1: The user moves the suction end of the upper suction pipe of the two sets of filter elements to the coolant recovery end of the five-axis linkage CNC machine tool. The negative pressure pump draws negative pressure into one set of cylinders through the first three-way valve and the conduit, promoting the coolant to enter the cylinder through the suction pipe. The filter cover in the filter element in the cylinder filters the solids in the coolant. The filtered coolant is discharged to the bottom of the cylinder through the filter hole on the side of the filter cover and discharged through the outlet pipe. When it is necessary to recover the solid impurities retained in the filter element in the filter element, the first three-way valve is reversed. At this time, the negative pressure pump draws negative pressure into the other set of cylinders through the first three-way valve and the conduit. At this time, the suction in the original cylinder is stopped, and the filter element in the other set of filter elements continuously separates the coolant from the solids.

[0017] Step 2: In Step 1, after the original filter element stops the debris-liquid separation operation, the top cover and the auger are inserted into the bottom of the filter cover. The second motor, gear assembly, sleeve, and cross shaft work together to drive the connecting shaft, auger, and top cover to rotate, and the material stuck at the bottom of the filter cover is discharged from the discharge shell and the discharge pipe.

[0018] Step 3: In step 2, the high-pressure gas generated by the high-pressure blower is ejected through the second three-way valve, branch pipe, third three-way valve, second pipe, and spray plate. The first motor drives the retaining ring and filter cover to rotate through the gear ring assembly, snap ring, and snap block. The high-pressure air ejected by the spray plate clears the filter holes on the side of the rotating filter cover, causing the third three-way valve to switch directions. At this time, the high-pressure air blows through the first pipe and the air jet ring onto the inner wall of the filter cover, promoting the shedding of solid impurities trapped on the inner wall of the filter cover.

[0019] Preferably, in step one, during the process of separating the coolant from the filter cover, the second airbag contracts under the pressure of the adjusting plate, and the gas in the second airbag is stored in the first airbag through the transition tube. The first airbag expands into the receiving groove on the inner side of the bottom of the filter cover, thereby sealing the bottom of the filter cover.

[0020] This invention provides a negative pressure chip-liquid separation and filtration device and method based on a five-axis CNC machine tool. Compared with the prior art, it has the following advantages:

[0021] (1) The negative pressure chip-liquid separation and filtration equipment and method based on a five-axis linkage CNC machine tool, by setting filter components in the device, allows the cylinder, cover shell, suction pipe, first motor, gear ring assembly, snap ring, snap block, retaining ring, filter cover, discharge shell, discharge pipe, auger, connecting shaft, cylinder, adjusting plate, cross shaft, sleeve, second motor, gear assembly, and outlet pipe to cooperate with each other. After separating the coolant chips and liquid, it has the function of exporting solid impurities that remain at the bottom of the filter end, avoiding blockage of the filter end by solid impurities, making it convenient for users to recover impurities at the filter end, and reducing subsequent operation steps.

[0022] (2) The negative pressure chip-liquid separation and filtration equipment and method based on a five-axis linkage CNC machine tool, by setting a leak-proof component in the device, allows the top cover, connecting shaft, first airbag, transition pipe and second airbag to cooperate with each other. When the filter cover is separating chips and liquid, it prevents the coolant from being discharged from the unloading part, thus playing a role in preventing leakage. In addition, before the impurities are retained in the filter cover, the first airbag is used to collect the leak-proof components, so that the unloading end of the device has a leak-proof function before unloading, avoiding the leakage of coolant from the solid impurity unloading end and causing waste, reducing the impact on the chip-liquid separation step and improving the coolant recovery rate.

[0023] (3) A negative pressure chip-liquid separation and filtration device and method based on a five-axis linkage CNC machine tool, by setting a negative pressure component in the device, the negative pressure pump, the first three-way valve, the two sets of conduits and the filter tank cooperate with each other, so that the two sets of filter elements can perform alternating and uninterrupted chip-liquid separation treatment of the coolant, thereby improving the chip-liquid separation efficiency of the device for the coolant, and adsorbing the odor emitted by the treatment liquid during the negative pressure extraction process, thereby reducing pollution.

[0024] (4) A negative pressure chip-liquid separation and filtration device and method based on a five-axis linkage CNC machine tool, by setting a dredging component in the device, the high pressure blower, the second three-way valve, the branch pipe, the third three-way valve, the first pipe, the jet ring, the second pipe, and the spray plate cooperate with each other to dredge the filter holes of the rotating filter cover driven by the drive component and promote the discharge of impurities on the inner wall. While cleaning the filter cover, it plays an auxiliary role in the discharge component, improves the discharge rate of solid impurities, and helps the subsequent filter cover to continue filtering the coolant.

The negative pressure pump 31, the first three-way valve 32, the two sets of conduits 33, and the filter tank 34 cooperate with each other to facilitate the two sets of filter elements 2 to perform alternating and uninterrupted separation of the coolant and adsorb the odor emitted by the treated liquid during the negative pressure extraction process, thereby reducing pollution.

[0044] The fourth embodiment differs from the third embodiment in that: the unblocking component 4 includes a high-pressure blower 41 mounted on the base 1, a second three-way valve 42 is installed at the outlet of the high-pressure blower 41, branch pipes 43 are provided on both sides of the second three-way valve 42, a third three-way valve 44 is installed at the top of the branch pipes 43, a first pipe 45 is installed at the upper end of the third three-way valve 44, a jet ring 46 fixedly connected to the first pipe 45 is installed on the lower side of the cover 22 near the upper end of the filter cover 252, a second pipe 47 is provided on the front side of the third three-way valve 44, and a spray plate 48 fixedly connected to the second pipe 47 is provided vertically on the inner side of the cylinder 21 corresponding to the side of the filter cover 252.

While cleaning the filter cover 252, it also plays an auxiliary role in the discharge component 26.

[0046] This invention also discloses a method for using a negative pressure chip-liquid separation and filtration device based on a five-axis linkage CNC machine tool, specifically including the following steps:

[0047] Step 1: The user moves the suction end of the upper suction pipe 23 of the two sets of filter elements 2 to the coolant recovery end of the five-axis CNC machine tool, and starts the negative pressure pump 31. The negative pressure pump 31 draws negative pressure into the cylinder 21 through the first three-way valve 32 and the conduit 33. Under the action of external negative pressure, the coolant is introduced into the cylinder 21 through the suction pipe 23. The filter cover 252 in the filter element 25 inside the cylinder 21 filters the solids in the coolant. The filtered coolant is discharged to the bottom of the cylinder 21 through the filter hole on the side of the filter cover 252. Then the coolant flows to the subsequent oil-water separation end through the outlet pipe 27. During oil-water separation, the negative pressure pump 31 draws gas and discharges it through the filter tank 34. The activated carbon mesh inside the filter tank 34 adsorbs the odor in the gas. When it is necessary to recover the solid impurities retained in the filter element 25 inside the filter element 2, the first three-way valve 32 is reversed. At this time, the negative pressure pump 31 draws negative pressure into another set of cylinders 21 through the first three-way valve 32 and the conduit 33. At this time, the material drawing in the original cylinder 21 is terminated. The filter element 25 in the other set of filter elements 2 performs continuous chip-liquid separation of the coolant. The solid impurities in the filter element 25 are retained on the top cover 2641.

[0048] Step Two: In Step One, after the original filter element 2 stops its debris-liquid separation operation, cylinder 2651 is activated. Cylinder 2651 drives the adjusting plate 2652, cross shaft 2653, connecting shaft 2642, auger 263, top cover 2641, first airbag 2643, transition pipe 2644, and second airbag 2645 to move upward. As the second airbag 2645 separates from the bottom of the base 1, the first airbag 2643 contracts and introduces gas into the second airbag 2645 through the transition pipe 2644, while the cross shaft 2653 slides vertically along the sleeve 2654. After the top cover 2641 and the auger 263 are inserted into the appropriate position at the bottom of the filter cover 252, the lower end of the discharge shell 261 and the filter cover 252 are connected. Some solid impurities fall into the filter cover 252. The second motor 2655 is started. The second motor 2655 drives the sleeve 2654, the cross shaft 2653, the connecting shaft 2642, the auger 263 and the top cover 2641 to rotate through the gear assembly 2656. The material stuck at the bottom of the filter cover 252 is continuously guided into the discharge shell 261 under the action of the rotating auger 263 and finally discharged through the discharge pipe 262.

[0049] Step 3: In Step 2, the high-pressure blower 41 and the first motor 241 are started. The high-pressure gas generated by the high-pressure blower 41 is ejected through the second three-way valve 42, branch pipe 43, third three-way valve 44, second pipe 47, and spray plate 48. The first motor 241 drives the retaining ring 251 and filter cover 252 to rotate through the gear ring assembly 242, snap ring 243, and snap block 244. The high-pressure air ejected by the spray plate 48 blows the filter holes on the side of the rotating filter cover 252, which clears the filter holes and promotes the solid impurities in the filter holes to fall into the filter cover 252. Then, the third three-way valve 44 is reversed. At this time, the high-pressure air blows the inner wall of the filter cover 252 through the first pipe 45 and the air jet ring 46 to promote the solid impurities trapped on the inner wall of the filter cover 252 to fall off and slide to the end of the auger 263, thereby improving the impurity recovery rate and cleaning and clearing the filter cover 252.

[0050] Meanwhile, all contents not described in detail in this specification are existing technologies known to those skilled in the art. In step one, during the process of separating the coolant by the filter cover 252, the second airbag 2645 contracts under the pressure of the adjusting plate 2652. The gas in the second airbag 2645 is stored in the first airbag 2643 through the transition pipe 2644. The first airbag 2643 expands into the receiving groove on the inner side of the bottom of the filter cover 252, thereby sealing the bottom of the filter cover 252 and preventing the coolant from seeping out through the discharge shell 261.

7. The method of using the negative pressure chip-liquid separation and filtration equipment based on a five-axis linkage CNC machine tool as described in claim 6, characterized in that: Specifically, the following steps are included: Step 1: The user moves the suction end of the upper suction pipe of the two sets of filter elements to the coolant recovery end of the five-axis linkage CNC machine tool. The negative pressure pump draws negative pressure into one set of cylinders through the first three-way valve and the conduit, promoting the coolant to enter the cylinder through the suction pipe. The filter cover in the filter element in the cylinder filters the solids in the coolant. The filtered coolant is discharged to the bottom of the cylinder through the filter hole on the side of the filter cover and discharged through the outlet pipe. When it is necessary to recover the solid impurities retained in the filter element in the filter element, the first three-way valve is reversed. At this time, the negative pressure pump draws negative pressure into the other set of cylinders through the first three-way valve and the conduit. At this time, the suction in the original cylinder is stopped, and the filter element in the other set of filter elements continuously separates the coolant from the solids. Step 2: In Step 1, after the original filter element stops the debris-liquid separation operation, the top cover and the auger are inserted into the bottom of the filter cover. The second motor, gear assembly, sleeve, and cross shaft work together to drive the connecting shaft, auger, and top cover to rotate, and the material stuck at the bottom of the filter cover is discharged from the discharge shell and the discharge pipe. Step 3: In step 2, the high-pressure gas generated by the high-pressure blower is ejected through the second three-way valve, branch pipe, third three-way valve, second pipe, and spray plate. The first motor drives the retaining ring and filter cover to rotate through the gear ring assembly, snap ring, and snap block. The high-pressure air ejected by the spray plate clears the filter holes on the side of the rotating filter cover, causing the third three-way valve to switch directions. At this time, the high-pressure air blows through the first pipe and the air jet ring onto the inner wall of the filter cover, promoting the shedding of solid impurities trapped on the inner wall of the filter cover.

8. The method of using the negative pressure chip-liquid separation and filtration equipment based on a five-axis linkage CNC machine tool according to claim 7, characterized in that: In step one, during the process of separating the coolant from the filter cover, the second airbag contracts under the pressure of the adjusting plate, and the gas in the second airbag is stored in the first airbag through the transition tube. The first airbag expands into the storage groove on the inner side of the bottom of the filter cover, thereby sealing the bottom of the filter cover.
