Description

Technical Field

[0001] The invention relates to the technical field of wastewater collection, in particular to a CNC lathe with a wastewater collection structure. Background Art

[0002] CNC lathe is a highly automated machine tool that integrates multiple technologies such as mechanics, electrical, and computer control. The machining process is controlled by pre-written programs. These programs contain detailed instructions such as tool motion trajectory and cutting parameters. Its main components include bed, spindle box, feed mechanism and tool holder. The bed provides stable support, the spindle box controls the rotation of the workpiece, the feed mechanism accurately guides the linear motion of the tool, and the tool holder is used to install the tool. When working, the CNC system interprets and processes the program, drives the spindle and tool to move according to the set requirements, and can accurately complete various machining operations such as turning outer circles, turning inner holes, and turning threads. During the turning process, the cooling nozzle will spray coolant to reduce the high temperature of the tool and the workpiece and ensure the machining accuracy. At the same time, the turning operation produces a large amount of metal debris, and the coolant and metal debris mix to form wastewater that splashes everywhere. Wastewater collection not only avoids environmental pollution caused by the arbitrary discharge of wastewater, but also can achieve the recycling and reuse of water resources through subsequent treatment, ensuring the sustainability of production and the balance of the ecological environment.

[0003] During the turning process, CNC lathes will generate a large amount of metal debris, which will mix with coolant to form wastewater.

[0008] The present invention provides a CNC lathe with a wastewater collection structure. It has the following beneficial effects:

[0009] 1. A CNC lathe with a wastewater collection structure is provided with a folding plate to guide the wastewater to flow to the concave part and enter the arc-shaped adsorption cylinder from the water hole, thereby increasing the contact area with the wastewater, allowing more solid matter to adhere to the surface, preventing the solid matter from accumulating at the water hole, and the water hole effectively intercepts large particles of metal solid matter. After completing the preliminary filtration, the wastewater is guided to flow smoothly and orderly into the arc-shaped adsorption cylinder. The arc-shaped ring plate effectively blocks the metal debris generated during turning and the splashing coolant. By using the principles of gravity and inertia, the splashing material is guided to flow along the inner wall to the concave part and out of the through hole, thereby realizing the preliminary orderly collection of the waste. The rotation of the spiral plate can stir the wastewater, so that the coagulant and the wastewater are mixed more evenly and the reaction is more sufficient.

[0010] 2. This CNC lathe with a wastewater collection structure is provided with a processing device. The folding plate guides the wastewater to flow to the concave part and enters the arc-shaped adsorption cylinder from the water hole, thereby increasing the contact area with the wastewater and allowing more solid matter to adhere to the surface to prevent solid matter from accumulating at the water hole. The water hole effectively intercepts large particles of metal solid matter. After completing the preliminary filtration, the wastewater is guided to flow smoothly and orderly into the arc-shaped adsorption cylinder. The arc-shaped adsorption cylinder increases the utilization rate of the internal space, increases the filling amount of activated carbon, and extends the contact path between the wastewater and the activated carbon, allowing organic pollutants in the wastewater to have more opportunities to contact with the pores on the surface of the activated carbon, thereby improving the adsorption efficiency of the activated carbon for organic pollutants such as oil stains. The scraper can effectively scrape off the sediment attached to the surface of the folding plate to ensure the cleanliness of the surface of the folding plate, so that it can continue to maintain a good filtration effect in subsequent wastewater treatment.

[0011] 3. A CNC lathe with a wastewater collection structure is provided with a processing device. The arc-shaped ring plate effectively blocks metal debris and splashing coolant generated during turning. The principle of gravity and inertia is used to guide the splashing materials to flow along the inner wall to the depression and out of the through hole, thereby realizing the preliminary orderly collection of wastewater. When the elastic sheet is impacted by the coolant, it can undergo elastic deformation and become concave inward. When the external force disappears, it rebounds by relying on its own elastic restoring force, and the attached wastewater is bounced off, thereby automatically completing the preliminary wastewater cleaning and reducing the accumulation and residue of wastewater on the surface of the component. When the coolant impact causes the elastic sheet to deform under force, the spring is compressed to store elastic potential energy, thereby offsetting the instantaneous large impact force caused by the impact of the wastewater, thereby ensuring that the elastic sheet can still work normally under multiple impacts. The concave scraper scrapes and cleans the wastewater on the inner wall of the arc-shaped ring plate. The scraper is set to be concave. When scraping, the solids in the wastewater can be gathered to the depression, so that the wastewater completely enters the oblique groove from the through hole.

[0012] 4. This CNC lathe with a wastewater collection structure is provided with a collecting device. The rotation of the spiral plate can stir the wastewater, so that the coagulant and wastewater are mixed more evenly and the reaction is more complete. At the same time, the spiral plate pushes the wastewater to do a spiral forward motion in the screening cylinder, thereby increasing the residence time of the wastewater in the cylinder and allowing the coagulation reaction to proceed fully. The screening cylinder rotates, and under the action of centrifugal force, the wastewater is subjected to secondary physical filtration to intercept some impurity particles that remain after coagulation and sedimentation, thereby further purifying the wastewater and, at the same time, accelerating the flow rate of water so that the wastewater can pass through quickly. The gradually shrinking hole is set as a circular hole with a small inside and a large outside. When the water flows through the gradually shrinking hole, the pressure is reduced and the speed is increased, so that the water can be thrown out of the gradually shrinking hole faster, thereby accelerating the flow rate of the wastewater and prompting the wastewater to pass through the screening cylinder quickly. The collecting box collects the completely purified wastewater. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The processing device 5 includes a processing table 51, the top of the processing table 51 is provided with an oblique groove 52, the bottom of the inner wall of the oblique groove 52 is provided with a rectangular groove 53, the inner wall of the rectangular groove 53 is fixedly connected with a folding plate 54, the top of the folding plate 54 is provided with a water hole 55, the bottom of the folding plate 54 is fixedly connected with an arc-shaped adsorption cylinder 56, the inner wall side of the rectangular groove 53 is provided with a rectangular groove 57, one side of the inner wall of the rectangular groove 57 is fixedly connected with an electric push rod 58, the movable end of the electric push rod 58 is fixedly connected with a scraper 59, the top of the processing table 51 is away from the oblique groove A slide groove 510 is provided on one side of the groove 52, a round hole 511 is provided in the middle of the top slide groove 510 of the processing table 51, a feed cover 512 is threadedly connected to the inner wall of the round hole 511, the bottom of the processing table 51 is fixedly connected to the bottom of the inner wall of the lathe body 1, and the side of the folding plate 54 is fixedly connected to one side of the collecting device 8. When in use, the workpiece to be turned is fixed on the three-jaw chuck 7, and the CNC board 2 sends precise control signals to each actuator through the electrical control system according to the coordinate data and motion instructions in the program to control the movement of the anti-splash device 6 The processing is carried out at the position of the lathe 3, and the cooling nozzle 4 sprays coolant to cool the processing part. The anti-splash device 6 blocks the metal debris and coolant splashed during processing and flows into the processing device 5 through the hole opened at the bottom of the anti-splash device 6. After the wastewater enters the processing device 5, it is filtered and adsorbed to filter the large solid particles and oil pollution in the wastewater.

The arc-shaped adsorption cylinder 56 has activated carbon arranged in it. The activated carbon has a huge specific surface area and its surface is covered with tiny pores. When the wastewater passes through the activated carbon, the organic pollutant molecules such as oil dissolved in the wastewater will be firmly adsorbed on the pore surface of the activated carbon under the action of the intermolecular adsorption force, thereby further purifying the wastewater. The arc-shaped adsorption cylinder 56 increases the contact time between the wastewater and the activated carbon and prolongs the reaction. After there is no wastewater on the surface of the folding plate 54, the electric push rod 58 is started to push the scraper 59 to scrape off the sediment on the surface of the folding plate 54 to prevent blockage.

[0025] For the second embodiment, please refer to Figure 1-Figure 8 The present invention provides a CNC lathe with a wastewater collection structure: the anti-splash device 6 includes a fixed plate 61 and a fan 611, one side of the fixed plate 61 is fixedly connected with an annular plate 62, the side of the annular plate 62 away from the fixed plate 61 is fixedly connected with an arc-shaped annular plate 63, the outer side of the arc-shaped annular plate 63 is provided with an annular groove 64, the inner wall of the annular groove 64 is slidably connected with a rotating plate 65, one side of the rotating plate 65 is fixedly connected with a connecting rod 66, the side of the connecting rod 66 away from the rotating plate 65 is fixedly connected with a concave scraper 67, and the inner side of the annular plate 62 is fixedly connected with an elastic sheet 68, a spring 69 is fixedly connected to one side of the fixed plate 61 close to the elastic sheet 68, a through hole 610 is provided at the inner bottom of the arc-shaped ring plate 63, a movable plate 612 is fixedly connected to one side of the fixed plate 61 away from the annular plate 62, a side of the fixed plate 61 close to the annular plate 62 is fixedly connected to one side of the three-jaw chuck 7, a side of the fan 611 is fixedly connected to one side of the inner wall of the lathe body 1, a side of the movable plate 612 is slidably connected to the inner wall of the slide groove 510, and a side of the spring 69 away from the fixed plate 61 is fixedly connected to one side of the elastic sheet 68 close to the fixed plate 61;

[0026] The collecting device 8 includes a sleeve plate 81 and a water pipe 89. The inner wall of the sleeve plate 81 is rotatably connected to a sieve cylinder 82. A gradually narrowing hole 83 is provided on the side of the sieve cylinder 82. A filtering hole 84 is provided on the side of the sieve cylinder 82 close to the sleeve plate 81. A rotating rod 85 is fixedly connected to one side of the inner wall of the sieve cylinder 82. One end of the rotating rod 85 passes through and is fixedly connected to a spiral plate 86. One end of the rotating rod 85 is fixedly connected to the driving shaft of a motor 87. A waterproof sleeve plate 88 is sleeved on the sieve cylinder 82 and rotatably connected. One end of the water pipe 89 is connected to a collecting box 810. One side of the sleeve plate 81 is fixedly connected to the inner wall of the rectangular groove 53. The side of the motor 87 is fixedly connected to one side of the inner wall of the rectangular groove 53. One side of the waterproof sleeve plate 88 is fixedly connected to the inner wall of the rectangular groove 53. The end of the water pipe 89 away from the collection box 810 is connected to one side of the processing table 51. When in use, when the turner 3 turns the workpiece, a large amount of metal debris will be generated. The cooling nozzle 4 cools the processed part and causes the coolant to splash everywhere. When the metal debris and the coolant hit the arc-shaped ring plate 63, due to its smooth surface and a certain inclination angle, under the action of gravity and inertia, the splashes flow along the inner wall of the arc-shaped ring plate 63 to the concave part, and finally flow out from the through hole 610. When the coolant is sprayed to the elastic sheet 68, the elastic sheet 68 undergoes elastic deformation and sinks inward. At the same time, the spring 69 connected to the elastic sheet 68 is compressed for buffering. Under the action of external force, the spring produces elastic deformation to store elastic potential energy, thereby offsetting the waste. The instantaneous large impact force brought by the water impact protects the elastic sheet 68 from damage. When the elastic sheet 68 is not subjected to external force, it rebounds by relying on the elastic recovery force of its own material, and the wastewater attached to its surface is bounced off. The fan 611 is started, and the fan 611 rotates to generate airflow, blowing the rotating plate 65 to slide along the annular slide groove 64. The rotating plate 65 slides stably under the push of the airflow, and then drives the concave scraper 67 to slide along the inner wall of the arc-shaped ring plate 63. During the sliding process, the concave scraper 67 scrapes off the wastewater remaining on the inner wall of the arc-shaped ring plate 63, and the purified wastewater enters the sieve cylinder 82 from the filter hole 84. The feed cover 512 is opened, and the coagulant is added into the rectangular groove 53. The coagulant is hydrolyzed in the water to form colloids. These colloids absorb tiny suspended particles and colloids in the wastewater. Impurities are collected and aggregated to form larger flocs. The motor 87 rotates to drive the spiral plate 86 and the sieve drum 82 to rotate. The rotation of the spiral plate 86 can stir the wastewater, so that the coagulant and wastewater are mixed more evenly and the reaction is more complete. At the same time, the spiral plate 86 pushes the wastewater to do a spiral forward motion in the sieve drum 82, thereby increasing the residence time of the wastewater in the drum and allowing the coagulation reaction to proceed fully. The rotation of the sieve drum 82 generates centrifugal force, and the water is accelerated to be thrown out from the gradually contracting hole 83. The gradually contracting hole 83 is set as a circular hole with a small inner part and a large outer part. When the water flows through the gradually contracting hole 83, the pressure is reduced and the speed is increased, so that the water can be thrown out from the gradually contracting hole 83 faster, thereby accelerating the flow rate of the wastewater and prompting the wastewater to pass through the sieve drum 82 quickly. Finally,The completely purified wastewater enters the collection box 810 from the water pipe 89 to complete the collection.

[0027] When the present invention is operated and used, the workpiece to be turned is fixed on the three-jaw chuck 7, and the CNC board 2 sends precise control signals to each execution component through the electrical control system according to the coordinate data and motion instructions in the program, and controls the anti-splash device 6 to move to the position of the turner 3 for processing. The cooling nozzle 4 sprays coolant to cool the processing area. The anti-splash device 6 blocks the metal debris and coolant splashed during processing and flows into the treatment device 5 through the hole opened at the bottom of the anti-splash device 6. After the waste water enters the treatment device 5 and is filtered and adsorbed, large particles of solids and oil and other substances in the waste water are filtered out, and the filtered waste water enters the collection device 8 to collect the treated waste water. When the turner 3 turns the workpiece, a large amount of metal Chips, the cooling nozzle 4 cools the processing area and causes the coolant to splash everywhere. When the metal chips and the coolant hit the arc-shaped ring plate 63, due to its smooth surface and a certain inclination angle, under the action of gravity and inertia, the splashes flow along the inner wall of the arc-shaped ring plate 63 to the concave part, and finally flow out from the through hole 610. When the coolant is sprayed to the elastic sheet 68, the elastic sheet 68 undergoes elastic deformation and concaves inward. At the same time, the spring 69 connected to the elastic sheet 68 is compressed for buffering. Under the action of external force, the spring produces elastic deformation and stores elastic potential energy, thereby offsetting the instantaneous large impact force brought by the impact of wastewater and protecting the elastic sheet 68 from damage. When the elastic sheet 68 is not subjected to external force, it rebounds by relying on the elastic recovery force of its own material and adheres to its surface The wastewater bounces off and the fan 611 is started. The fan 611 rotates to generate airflow, which blows the rotating plate 65 to slide along the annular groove 64. The rotating plate 65 slides stably under the push of the airflow, and then drives the concave scraper 67 to slide along the inner wall of the arc-shaped ring plate 63. During the sliding process, the concave scraper 67 scrapes off the wastewater remaining on the inner wall of the arc-shaped ring plate 63. The wastewater flowing into the rectangular groove 53 passes through the folding plate 54 to filter the large particles of metal solid substances. The wastewater flows into the arc-shaped adsorption cylinder 56 from the water hole 55. Activated carbon is arranged in the arc-shaped adsorption cylinder 56. The activated carbon has a huge specific surface area and its surface is covered with tiny pores. When the wastewater passes through the activated carbon, the organic pollutant molecules such as oil dissolved in the wastewater will be firmly adsorbed in the pores of the activated carbon under the action of the intermolecular adsorption force. The surface of the gap is further purified. The arc-shaped adsorption cylinder 56 increases the contact time between the wastewater and the activated carbon to prolong the reaction. After there is no wastewater on the surface of the folding plate 54, the electric push rod 58 is started to push the scraper 59 to scrape the sediment on the surface of the folding plate 54 to prevent clogging. The purified wastewater enters the screening cylinder 82 from the filter hole 84. The feed cover 512 is opened, and the coagulant is added to the inside of the rectangular groove 53. The coagulant is hydrolyzed in the water to form a colloid. These colloids absorb the tiny suspended particles and colloidal impurities in the wastewater, causing them to aggregate to form larger flocculent precipitation. The motor 87 rotates to drive the spiral plate 86 and the screening cylinder 82 to rotate. The rotation of the spiral plate 86 can stir the wastewater, so that the coagulant and the wastewater are mixed more evenly and the reaction is more complete. At the same time,The spiral plate 86 pushes the wastewater to do spiral forward motion in the screening cylinder 82, increasing the residence time of the wastewater in the cylinder, allowing the coagulation reaction to be fully carried out. The rotation of the screening cylinder 82 generates centrifugal force, and the water is accelerated to be thrown out from the gradually contracting hole 83. The gradually contracting hole 83 is set as a circular hole with a small inner part and a large outer part. When the water flows through the gradually contracting hole 83, the pressure is reduced and the speed is increased, so that the water can be thrown out from the gradually contracting hole 83 faster, speeding up the flow rate of the wastewater, and enabling the wastewater to pass through the screening cylinder 82 quickly. Finally, the completely purified wastewater enters the collection box 810 from the water pipe 89 to complete the collection.

[0028] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
