Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a machine tool chip discharge wastewater treatment device with multi-stage waste chip and oil treatment. Background Technology

[0002] During the machine tool processing and production process, a large amount of mixed wastewater containing metal scraps and oil is generated. Direct discharge of this wastewater not only pollutes the environment but also wastes water resources. Therefore, a dedicated wastewater treatment device is needed for purification. Currently, similar wastewater treatment equipment typically first intercepts metal scraps in the wastewater through a multi-stage filtration mechanism to achieve preliminary solid-liquid separation. Then, demulsifying agents are added to the wastewater for mixing and reaction, followed by settling to separate oil, water, and sludge.

[0003] Referring to the wastewater treatment device for compressor parts production disclosed in patent application CN215798921U, by setting up a screen cylinder, a collection tank and a drain valve, the screen cylinder can collect metal fragments contained in the wastewater, preventing the metal fragments from being sucked into the wastewater treatment equipment. When the main body of the device is not in use, the metal fragments will fall into the collection tank under the influence of gravity. Then, the drain valve can be opened periodically to treat the collected metal fragments in a unified manner, thereby improving the wastewater treatment effect.

[0004] A comprehensive analysis of the above-mentioned patents reveals the following shortcomings: Existing multi-stage waste chip and oil pollution treatment devices for machine tool wastewater typically first use a multi-stage filtration system to intercept and filter metal waste in the wastewater. Then, a demulsifying agent is added to the wastewater to induce a demulsification reaction, followed by settling and stratification to complete the purification process. However, during the addition of the agent, it is difficult to dynamically change the diffusion range of the agent to ensure rapid and thorough mixing with the wastewater, affecting the efficiency of the subsequent demulsification reaction. Furthermore, the treatment units are not divided into zones; each batch must complete sedimentation before continuing treatment, resulting in low overall efficiency. Therefore, it is necessary to provide a multi-stage waste chip and oil pollution treatment device for machine tool wastewater to solve the above technical problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-stage waste chip and oil pollution treatment device for machine tool wastewater. It solves the problems of difficulty in dynamically changing the diffusion range of the reagents during the process of adding reagents to the wastewater, which makes it difficult to quickly and fully mix the reagents with the wastewater, thus affecting the efficiency of the subsequent demulsification reaction. Furthermore, the treatment units do not operate in separate zones and can only continue processing after each batch of sedimentation is completed, resulting in low overall treatment efficiency.

[0016] Beneficial effects This invention provides a multi-stage waste chip and oil pollution treatment device for machine tool wastewater. Compared with the prior art, it has the following advantages: (1) The multi-stage waste oil treatment machine tool chip discharge wastewater treatment device can achieve integrated and efficient treatment of solid-liquid separation, reagent mixing, demulsification reaction and sedimentation layering through the cooperation between the multi-stage filtration mechanism, chemical treatment box mechanism and sedimentation mechanism. The chemical treatment box mechanism adopts multi-point uniform drug distribution and oscillation enhanced mixing, and is combined with passive water flow stirring, so that the demulsification agent and wastewater can be quickly and fully mixed, making the subsequent demulsification reaction more thorough. At the same time, the chemical treatment and sedimentation are separated and operated independently, and can be continuously fed, continuously reacted and continuously precipitated without stopping the machine. The degree of automation is high, which greatly improves the treatment efficiency and the treatment volume per unit time, and achieves stable, efficient and continuous purification treatment of machine tool chip discharge wastewater.

[0017] (2) The multi-stage waste chip and oil pollution treatment device for machine tool wastewater treatment, through the cooperation between hollow rods, short pipes, square frames, convex plates, eccentric wheels and support rods, adopts a dual-enhancement method of multi-point uniform drug distribution and swing-type mixing, which greatly improves the mixing effect of demulsifying agent and oil pollution wastewater. The demulsifying agent is discharged through the discharge pipe, hollow rods and short pipes to the square frame, and is sprayed by multiple sets of spray nozzles at multiple points, synchronously and uniformly, which effectively avoids excessive local concentration of the agent and ensures uniform initial distribution. At the same time, the eccentric wheel is driven to rotate by the geared motor, and the drive rod moves up and down under the action of the spring. The support rod moves the convex plate to make the square frame swing back and forth around the short axis, which can dynamically change the diffusion range of the agent, further increase the contact area and contact rate with the wastewater, and make the agent diffuse quickly, significantly improving the mixing uniformity and demulsification reaction efficiency, laying a good foundation for subsequent sedimentation and separation.

[0018] (3) The multi-stage waste chip and oil pollution treatment device for machine tool wastewater treatment, through the cooperation between the square frame, filter screen, impeller and mixing blades, when the square frame swings back and forth around the short axis, the water flow in the box will impact the impeller in the filter screen. The water flow will passively drive the vertical shaft and mixing blades to rotate. When the mixing blades rotate, they will form strong shear and disturbance on the wastewater and demulsifying agent, further improving the mixing speed and uniformity. This can effectively avoid the problem of insufficient local mixing, so that the demulsifying agent and oily wastewater can quickly and fully contact and react, making the demulsification effect more thorough. This provides a stable and reliable reaction basis for subsequent sedimentation and stratification and oil-water separation, improving the overall wastewater treatment quality and efficiency.

[0019] (4) The multi-stage waste chip and oil stain treatment machine tool chip discharge wastewater treatment device operates independently in the chemical treatment box mechanism and the sedimentation mechanism. After the mixing reaction is completed in the chemical treatment box mechanism, the mixed liquid can be transported to the sedimentation mechanism through the outlet pipe for settling. At the same time, the chemical treatment box mechanism can continue to receive the next batch of wastewater filtered by the multi-stage filtration mechanism through the inlet pipe. The device automatically controls the liquid inlet, chemical dosing and material discharge through solenoid valve one, solenoid valve two and pump body. There is no need to stop the machine to wait for the single batch of sedimentation to be completed. It can realize continuous and assembly line treatment and greatly improve the processing capacity per unit time.

[0024] This invention provides two technical solutions: like Figure 1The first embodiment is shown: a machine tool chip discharge wastewater treatment device for multi-stage waste chip and oil treatment, including a multi-stage filtration mechanism 1 and a wastewater inlet pipe 2 disposed in front of the multi-stage filtration mechanism 1, and further including: The sedimentation mechanism 4 is used to load the machine tool chip discharge oil wastewater after it is uniformly mixed with the demulsifying agent, and to let it settle and separate into layers. The sedimentation mechanism 4 is located to the left of the multi-stage filtration mechanism 1.

[0025] Through the coordinated operation of the multi-stage filtration mechanism 1, the chemical treatment chamber mechanism 3, and the sedimentation mechanism 4, the integrated and efficient treatment of solid-liquid separation, reagent mixing, demulsification reaction, and sedimentation stratification can be achieved. The chemical treatment chamber mechanism 3 adopts multi-point uniform drug distribution and oscillating enhanced mixing, combined with passive water flow stirring, so that the demulsifying agent and wastewater can be quickly and fully mixed, making the subsequent demulsification reaction more thorough. At the same time, the chemical treatment and sedimentation are separated and operate independently, allowing for continuous feeding, continuous reaction, and continuous sedimentation without downtime. The high degree of automation significantly improves the treatment efficiency and the throughput per unit time, and the overall system achieves stable, efficient, and continuous purification treatment of machine tool chip discharge wastewater.

[0026] like Figures 2 to 11The second embodiment is shown, and its main difference from the first embodiment is that: a multi-stage waste chip and oil stain treatment machine tool wastewater treatment device, the chemical treatment box mechanism 3 includes a support frame 31, a treatment box 32 is arranged at the top of the inner cavity of the support frame 31, a plurality of hollow rods 33 are evenly fixedly arranged from front to back on the left side of the inner cavity of the treatment box 32, a drug discharge pipe 34 is fixedly inserted through the upper part of the plurality of hollow rods 33, the rear end of the drug discharge pipe 34 is fixedly inserted through the rear wall of the treatment box 32, a drug discharge mixing component 35 is rotatably arranged between the upper and lower right parts of each hollow rod 33 and the right wall of the inner cavity of the treatment box 32, and a plurality of drive frame assemblies 36 are evenly arranged from front to back on the right side of the inner cavity of the treatment box 32, the plurality of drive frame assemblies 36 correspond one-to-one with the plurality of hollow rods 33. A loading box 37 is fixedly installed on the top right side of the processing box 32. A rotating shaft 38 is rotatably installed between the front and rear walls of the inner cavity of the loading box 37. An eccentric wheel 39 is fixedly sleeved on both the front and rear parts of the rotating shaft 38. A reduction motor 310 is fixedly installed on the top of the processing box 32 in front of the loading box 37. The front end of the rotating shaft 38 rotatably passes through the front wall of the loading box 37 and is fixedly connected to the output end of the reduction motor 310. A pump body 311 is fixedly installed on the left rear end of the processing box 32. The liquid suction end of the pump body 311 is fixedly connected to a drug inlet bend 312. The end of the drug inlet bend 312 away from the pump body 311 is fixedly inserted to the bottom of the inner cavity of the medicine tank. The liquid discharge end of the pump body 311 is fixedly connected to the rear end of the drug discharge pipe 34. The front end of the top right side of the processing box 32 is connected to the multi-stage filtration mechanism 1. The two parts are fixedly connected by an inlet pipe 313. The bottom left side of the treatment box 32 is fixedly connected to the sedimentation mechanism 4 by an outlet pipe 314. Solenoid valves are fixedly installed on the right side of both the inlet pipe 313 and the outlet pipe 314. Each drug discharge and mixing component 35 includes a square frame 351. The inside of the square frame 351 is hollow. A short conduit 352 is fixedly connected to the middle left side of the square frame 351. The left end of the short conduit 352 is rotatably connected to the right wall of the corresponding hollow rod 33. A short shaft 353 is fixedly installed in the middle right side of the square frame 351. The right end of the short shaft 353 is rotatably connected to the right wall of the inner cavity of the treatment box 32. Several spray nozzles 354 are fixedly installed at the front and rear of the square frame 351. The left and right walls of the inner cavity of the square frame 351 are connected to each other. A support plate 355 is fixedly installed between the front and rear walls. A filter screen cover 356 is fixedly installed at the top center of each support plate 355. A vertical shaft 357 is rotatably inserted through the bottom center of the filter screen cover 356. An impeller 358 located inside the filter screen cover 356 is fixedly installed at the top of the vertical shaft 357. The bottom of the vertical shaft 357 is rotatably inserted through the bottom of the support plate 355. Several mixing blades 359 are evenly fixedly installed around the lower outer side of the vertical shaft 357. A protruding plate 3510 is fixedly installed at the right rear end of the square frame 351. The internal parts of the discharge pipe 34, several hollow rods 33, square frame 351, and short guide tube 352 are in a connected state. Each drive frame assembly 36 includes a drive rod 361. Two U-shaped limiting sleeves 362 are slidably sleeved on the outside of the drive rod 361.Two U-shaped limiting sleeves 362 are fixedly connected to the upper and lower parts of the right wall of the inner cavity of the processing box 32 on their right sides, respectively. Support rods 363 are fixedly installed at the front end of the drive rod 361, above and below the adjacent drug dispensing and mixing assembly 35. Two adjacent support rods 363 are located above and below the corresponding protruding plates 3510, respectively. The top of the drive rod 361 slides through the top of the processing box 32 and is fixedly installed with a top plate 364. The top plate 364 is located inside the loading box 37, and its top is in contact with the lower surface of the corresponding eccentric wheel 39. A spring 365 is sleeved on the outside of the drive rod 361, located between the bottom of the top plate 364 and the top of the processing box 32.

[0027] Through the coordinated operation of the hollow rod 33, short conduit 352, square frame 351, convex plate 3510, eccentric wheel 39, and support rod 363, a dual-enhanced method of multi-point uniform drug distribution and oscillating mixing is adopted to significantly improve the mixing effect of demulsifying agent and oily wastewater. The demulsifying agent is discharged through the discharge pipe 34, hollow rod 33, and short conduit 352 to the square frame 351, and then sprayed synchronously and uniformly by multiple sets of spray nozzles 354, effectively avoiding excessively high local concentrations of the agent and ensuring uniform initial distribution. At the same time, the geared motor 310 drives the eccentric wheel 39 to rotate. Rotation, driven by spring 365, drives drive rod 361 to reciprocate up and down. Support rod 363 actuates convex plate 3510, causing square frame 351 to swing back and forth around short axis 353. This dynamically changes the diffusion range of the reagent, further increasing the contact area and contact rate with wastewater, enabling rapid reagent diffusion, significantly improving mixing uniformity and demulsification efficiency, and laying a good foundation for subsequent sedimentation and separation. Through the cooperation between square frame 351, filter screen 356, impeller 358, and mixing aid blades 359, the square frame 351 rotates around short axis 353. During the reciprocating oscillation of the filter screen 356, the water flow inside the tank impacts the impeller 358 within the screen cover 356. This water flow passively drives the vertical shaft 357 and the mixing aid blades 359 to rotate. The rotation of the mixing aid blades 359 creates strong shearing and disturbance on the wastewater and demulsifying agent, further enhancing the mixing speed and uniformity. This effectively avoids the problem of insufficient mixing in certain areas, allowing the demulsifying agent and oily wastewater to quickly and fully react, resulting in a more thorough demulsification effect. This provides a stable and reliable reaction basis for subsequent sedimentation and stratification, and oil-water separation, ultimately improving the overall wastewater treatment quality. With improved efficiency, the chemical treatment tank mechanism 3 and the sedimentation mechanism 4 operate independently in separate zones. After the mixing reaction is completed in the chemical treatment tank mechanism 3, the mixed liquid can be transported to the sedimentation mechanism 4 through the outlet pipe 314 for settling. At the same time, the chemical treatment tank mechanism 3 can continue to receive the next batch of wastewater filtered by the multi-stage filtration mechanism 1 through the inlet pipe 313. The device automatically controls the liquid inlet, chemical dosing, and material discharge through solenoid valve 1, solenoid valve 2 and pump body 311. There is no need to stop the machine to wait for the sedimentation of a single batch to be completed. It can achieve continuous and assembly line treatment, which greatly improves the processing capacity per unit time.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] In use, the wastewater containing shavings and oil generated by the machine tool is transported to the multi-stage filtration mechanism 1 through the inlet pipe 2. The multi-stage filtration mechanism 1 is a prior art known to those skilled in the art. The multi-stage filtration mechanism 1 mainly consists of a multi-stage filter frame, a coarse filter, a fine filter, a sludge collection tank, and a slag discharge port. The wastewater flows sequentially through the coarse filter and the fine filter. The coarse filter first intercepts large metal shavings, and the fine filter filters out fine debris. The filtered impurities fall into the sludge collection tank and are periodically discharged through the slag discharge port, achieving preliminary solid-liquid separation. Then, the solenoid valve 2 on the inlet pipe 313 is opened, and the wastewater filtered in the multi-stage filtration mechanism 1 flows into the inner cavity of the treatment tank 32 through the inlet pipe 313. After the wastewater reaches the preset treatment volume, the solenoid valve 2 is closed, and the pump body 311 is started. The pump body 311 is circulated... The liquid demulsifying agent in the agent tank is extracted through the inlet bend 312. The demulsifying agent is then transported to the discharge pipe 34 through the discharge end of the pump body 311, and then evenly distributed into the interior of each hollow rod 33. The agent in the hollow rod 33 enters the inner cavity of the square frame 351 of each discharge and mixing component 35 through the short conduit 352, and is finally evenly sprayed into the wastewater in the treatment tank 32 through the spray nozzles 354 at the front and rear of the square frame 351. At the same time, the reduction motor 310 is started, which drives the rotating shaft 38 to rotate. The eccentric wheels 39 at the front and rear of the rotating shaft 38 rotate synchronously. The eccentric wheels 39 press down on the top plate 364. With the rebound action of the spring 365, the drive rod 361 is driven to make a reciprocating linear motion along the U-shaped limit sleeve 362. The drive rod 361 is moved up and down by the support rod 363. The protruding plate 3510 on the movable square frame 351 causes the square frame 351 to reciprocate around its short axis 353, further expanding the mixing range of the reagent and wastewater and improving the demulsification reaction efficiency. During the reciprocating motion of the square frame 351 around its short axis 353, the water in the treatment tank 32 flows through the filter screen 356 and impacts the impeller 358, causing the impeller 358 to rotate. This, in turn, drives the mixing aid blades 359 to rotate via the vertical shaft 357. During the rotation of the mixing aid blades 359, the wastewater and reagent are further stirred, ensuring that the wastewater and demulsifying reagent are quickly and completely mixed. Then, the solenoid valve two on the outlet pipe 314 is opened, and the wastewater in the treatment tank 32, which is uniformly mixed with the demulsifying reagent, is completely transported through the outlet pipe 314 to the inner cavity of the sedimentation mechanism 4. A transfer pump is installed at the bottom right side of the sedimentation mechanism 4. Opening the solenoid valve two on the outlet pipe 314 starts the transfer pump. Under the pressure of the transfer pump, the wastewater, completely mixed with the demulsifying agent in the treatment tank 32, is completely transported to the inner cavity of the sedimentation mechanism 4 through the outlet pipe 314. Closing the solenoid valve two on the outlet pipe 314 allows the wastewater to undergo a demulsification reaction within the sedimentation mechanism 4, followed by settling and stratification. The wastewater filtered by the multi-stage filtration mechanism 1 then flows back into the treatment tank 32 through the inlet pipe 313, achieving continuous and uninterrupted wastewater treatment, improving the overall treatment efficiency and equipment utilization. A transparent observation window is fixedly installed at the front end of the sedimentation mechanism 4 for observation. The demulsified oil floats on the surface of the water, while the purified water is in the middle layer.Impurities and sludge settle at the bottom of the inner cavity of the sedimentation mechanism 4. Open the solenoid valve 1 on the oil drain pipe 5, and the oil sludge on the upper layer of the sedimentation mechanism 4 is discharged and collected through the oil drain pipe 5. After the oil sludge is drained, close the solenoid valve. Open the solenoid valve 1 on the drain pipe 6, and the purified water in the middle layer of the sedimentation mechanism 4 is discharged through the drain pipe 6. After the purified water is drained, close the solenoid valve. Open the solenoid valve 1 on the sewage drain pipe 7, and the sludge and impurities settled at the bottom of the inner cavity of the sedimentation mechanism 4 are discharged through the sewage drain pipe 7. After sewage discharge is completed, close the solenoid valve, thus completing the treatment operation of the machine tool chip discharge wastewater.
