Description

Technical Field

[0001] The invention relates to the field of filtration, and in particular to a scraper-type recovery and filtration device for treating metal waste chips. Background Art

[0002] When a CNC machine tool processes parts, in order to ensure the quality of the processed parts and protect the CNC tools, the CNC tools and the processed parts are lubricated with cutting oil, and the CNC tools and the processed parts are also cooled. After the CNC machine tool completes the processing of the parts, the cutting oil needs to be recycled and the metal chips in the cutting oil are separated. For example, Chinese patent No. CN115646057A discloses a cutting oil fine chip filtering device for a machine tool, which performs preliminary precipitation of the cutting oil in a sedimentation barrel, and the cutting oil in the sedimentation barrel overflows through the oil drain hole to the space between the sedimentation box and the rotating barrel. The rotating motion of the rotating barrel drives the cutting oil inside the sedimentation box to perform centrifugal motion, and the iron chips remaining in the cutting oil can be thrown onto the side wall of the sedimentation box. At the same time, the cutting oil will fall onto the filter plate through the oil outlet at the bottom. The filter plate filters the cutting oil and can effectively remove the remaining fine iron chips.

[0003] However, after the cutting oil is completely filled into the sedimentation barrel, when no cutting oil is further added into the sedimentation barrel, the last remaining cutting oil in the sedimentation barrel cannot overflow from the oil drain hole to the space between the sedimentation box and the rotating barrel for centrifugal treatment.

[0022] The sedimentation assembly includes an electric push rod 1010, a push plate 1011, an adsorption cotton 1012, a round rod 1013, a guide plate 1014, a one-way valve 1015 and a spring rod 1021; the connecting plate 103 is bolted to the electric push rod 1010; the telescopic end of the electric push rod 1010 is fixedly connected to the push plate 1011, and the push plate 1011 is slidably connected to the sedimentation barrel 104; the push plate 1011 is detachably connected to the adsorption cotton 1012; the push plate 1011 is slidably connected to the round rod 1013; the push plate 1011 is fixedly connected to a plurality of spring rods 1021, and the telescopic ends of the spring rods 1021 are connected to the round rods 1013; the round rods 1013 are fixedly connected to the guide plates 1014; the guide plates 1014 are fixedly connected to a plurality of one-way valves 1015, and the one-way valves 1015 only allow the liquid to flow from one side of the adsorbent cotton 1012 to one side of the guide plate 1014.

[0023] It also includes an elastic ring 1016 and an air pipe 1017; the sedimentation barrel 104 is provided with an annular groove 1042; the sedimentation barrel 104 is fixedly connected with the elastic ring 1016, and the elastic ring 1016 is located on the annular groove 1042; the sedimentation barrel 104 is fixedly connected with two air pipes 1017, and the air pipes 1017 are connected to the closed cavity formed by the elastic ring 1016 and the annular groove 1042.

[0024] It also includes a magnet 1018; the magnet 1018 is fixedly connected to the inner side of the sedimentation barrel 104, and the magnet 1018 is located in the annular groove 1042. The metal chips in the cutting oil are adsorbed by the magnet 1018, so that the metal chips move toward the annular groove 1042 under the action of magnetic attraction, and then the metal chips fall and adhere to the adsorption cotton 1012.

[0025] The upper side of the adsorption cotton 1012 is low in the middle and high around, so that the chips in the cutting oil are easily settled to the center of the adsorption cotton 1012 under the action of gravity, so that the chips are relatively evenly attached to the adsorption cotton 1012, thereby improving the adsorption effect.

[0026] When in use, the external air pump is connected to the air delivery pipe 1017, and then the external pump is controlled to deliver the cutting oil to the oil inlet pipe 108 through the external pipeline, and finally the oil inlet pipe 108 enters the sedimentation barrel 104 for sedimentation. As the cutting oil is continuously added to the sedimentation barrel 104, the fine chips are precipitated downward, and the fine chips flow to the annular groove 1042 under the guidance of the guide plate 1014, and finally flow from the gap between the annular groove 1042 and the guide plate 1014 to the adsorption cotton 1012 to be adsorbed. After the sedimentation barrel 104 is filled with cutting oil, the cutting oil in the upper layer of the sedimentation barrel 104 flows from the overflow port 1041 to the space formed by the inner side of the tank body 102, the outer side of the centrifugal barrel 105 and the ring 109. Next, the motor of the control driver 106 is started, and the output shaft of the motor drives the gear to rotate, the gear drives the gear ring to rotate, and the gear ring drives the centrifugal barrel 105, the filter ring 1019, the oil outlet ring 1020 and the circular ring 109 to rotate, thereby centrifuging the cutting oil in the space formed by the tank body 102, the centrifugal barrel 105 and the circular ring 109, and the metal chips are thrown outward to the inner wall of the tank body 102 under the action of centrifugal force, and the cutting oil is filtered by the filter ring 1019 and flows out from the oil outlet ring 1020 for collection.

[0027] When no cutting oil is added to the sedimentation barrel 104, it is necessary to discharge the last remaining cutting oil in the sedimentation barrel 104 from the overflow port 1041 to the outside of the centrifugal barrel 105. At this time, the control driver 106 keeps the centrifugal barrel 105, the filter ring 1019, the oil outlet ring 1020 and the circular ring 109 rotating continuously, and then the oil inlet pipe 108 is manually closed, and then the electric push rod 1010 is controlled to make the push plate 1011 drive the adsorption cotton 1012, the round rod 1013 and the guide plate 1014 to move upward until the guide plate 1014 is flush with the overflow port 1041. At this time, the guide plate 1014 contacts the cover plate 107, and then the guide plate 1014 pushes the remaining cutting oil in the sedimentation barrel 104 from the overflow port 1041 to the outside of the centrifugal barrel 105. Figure 5 As shown, the centrifugal bucket 105 continues to centrifuge the cutting oil, and then; Then, the motor is controlled to start, and the output shaft of the motor drives the rotating rod 101 to rotate, so that the rotating rod 101 drives the tank body 102 and the connecting plate 103 to turn 180 degrees. Figure 6 As shown, since the adsorption cotton 1012 is separated from the annular groove 1042, the metal chips adsorbed on the adsorption cotton 1012 will not fall downward. Then, the electric push rod 1010 is controlled to make the push plate 1011 continue to move downward, the push plate 1011 and the round rod 1013 slide against each other, and the spring rod 1021 is compressed, so that the push plate 1011 pushes the adsorption cotton 1012 to the side of the guide plate 1014, so that the cutting oil remaining in the adsorption cotton 1012 flows out from the one-way valve 1015. The outflowing cutting oil passes through the guide of the cover plate 107 and flows from the overflow port 1041 to the ring 109 for centrifugation, and then the last remaining cutting oil in the sedimentation barrel 104 is centrifuged.

[0028] Since some cutting oil will remain in the annular groove 1042, during normal sedimentation, the air pipe 1017 is evacuated by controlling the external air pump to make the closed cavity formed by the elastic ring 1016 and the annular groove 1042 in a vacuum state, so that the elastic ring 1016 fits inwardly into the annular groove 1042 under the pressure of the cutting oil, and the cutting oil can flow normally to the adsorbent cotton 1012 through the gap between the guide plate 1014 and the annular groove 1042. When the adsorbent cotton 1012 moves upward, the external air pump is controlled to inflate the air pipe 1017, so that the elastic ring 1016 protrudes and contacts the adsorbent cotton 1012, and then the adsorbent cotton 1012 scrapes off the cutting oil attached to the elastic ring 1016.

[0029] After all the residual cutting oil in the sedimentation barrel 104 is centrifugally separated, the electric push rod 1010 is controlled to make the push plate 1011 drive the adsorption cotton 1012, the round rod 1013 and the guide plate 1014 to move downward until the guide plate 1014 is separated from the cover plate 107. The round rod 1013 and the guide plate 1014 move upward under the elastic force of the spring rod 1021, so that the guide plate 1014 and the adsorption cotton 1012 are separated, and the reset is completed. Subsequently, the motor is controlled to start again, and the output shaft of the motor drives the rotating rod 101 to rotate, so that the rotating rod 101 drives the tank body 102 and the connecting plate 103 to turn 180 degrees back to the initial state. Figure 2 Status shown.

[0030] Example 2 On the basis of Example 1, Figure 4-Figure 5 As shown, a motor 201 is also included; the push plate 1011 is bolted to the motor 201, and the output shaft of the motor 201 is slidably connected to the round rod 1013 through a spline.

[0031] It also includes a scraper bar 202; the scraper bar 202 is fixedly connected to the round rod 1013, and the scraper bar 202 is in contact with the adsorption cotton 1012, and the scraper bar 202 is made of rubber.

[0032] It also includes a cylinder 203; the filter ring 1019 and the centrifugal bucket 105 are detachably connected, and the filter ring 1019 is detachably connected to the corresponding circular ring 109; the oil outlet ring 1020 is detachably connected to the centrifugal bucket 105; the circular ring 109 is slidably connected to the tank body 102; each circular ring 109 is provided with a slide groove 1092; the connecting plate 103 is bolted to two cylinders 203 distributed up and down, and the telescopic end of the cylinder 203 is slidably connected to the corresponding slide groove 1092.

[0033] It also includes a temporary storage groove 1091; each ring 109 is provided with a temporary storage groove 1091. When the cutting oil is centrifuged, the metal chips are thrown to the edge of the tank body 102 and the ring 109 under the action of centrifugal force, and the metal chips are temporarily stored in the temporary storage groove 1091 to facilitate the subsequent collection of the metal chips. It should be noted that the impurities between the two temporary storage grooves 1091 remain on the inner wall of the tank body 102 and have no effect on the separation of the cutting oil. After the centrifugal separation is completed, the impurities remaining on the inner wall of the tank body 102 can be cleaned manually.

[0034] After the guide plate 1014 moves to be flush with the overflow port 1041 and the tank body 102 and the connecting plate 103 are flipped 180 degrees, the control motor 201 is started, and the guide plate 1014 is driven to rotate through the output shaft of the motor 201 to throw the cutting oil attached to the guide plate 1014 to the outside of the centrifugal barrel 105.

[0035] In such Figure 2 During normal centrifugation as shown, the cylinder 203 on the upper side is controlled to drive the corresponding ring 109 to move downward, so that the ring 109 is separated from the corresponding filter ring 1019. Then, the filter ring 1019 on the upper side can be taken out and cleaned manually, and the filter ring 1019 can be turned upside down to be as shown in FIG. Figure 6 After reaching the state shown, the upper cylinder 203 is controlled to drive the corresponding ring 109 to move downward, so that the ring 109 is separated from the corresponding filter ring 1019. Then, the corresponding filter ring 1019 can be taken out and cleaned manually. At the same time, the ring 109 scrapes the inner wall of the tank body 102 to scrape the cutting oil attached to the inner wall of the tank body 102 downward, thereby improving the separation and collection efficiency of the cutting oil.

[0036] When the cutting oil is settling, the chips flow along the guide plate 1014 from the gap between the guide plate 1014 and the annular groove 1042 to the edge of the adsorbent cotton 1012, so that more chips are attached to the edge of the adsorbent cotton 1012. Therefore, when settling, the control motor 201 is started, and the round rod 1013 drives the guide plate 1014 and the scraper bar 202 to rotate through the output shaft of the motor 201, so that the scraper bar 202 scrapes the chips attached to the edge of the adsorbent cotton 1012 toward the middle of the adsorbent cotton 1012, so that the chips are relatively even on the edge of the adsorbent cotton 1012. It should be noted that since the scraper bar 202 is made of rubber, when the adsorbent cotton 1012 squeezes the guide plate 1014, the scraper bar 202 is also squeezed, and the scraper bar 202 will not affect the extrusion process of the adsorbent cotton 1012 and the guide plate 1014.

[0037] Example 3 Based on Example 2, an electric heating wire is arranged inside the ring 109 .

[0038] When the cutting oil is centrifuged at low temperatures in winter, since the fluidity of the cutting oil is relatively poor at low temperatures, the electric heating wire in the ring 109 is controlled to be energized so that the ring 109 heats the cutting oil in the tank body 102 to enhance the fluidity of the cutting oil and improve the centrifugal separation efficiency.

[0039] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
