Description

A cutting fluid purification mechanism for casting processing Technical Field

[0001] This invention relates to the field of cutting fluid purification technology, specifically a cutting fluid purification mechanism for casting processing. Background Technology

[0002] Cutting fluid is required in casting processing, and the resulting waste cutting fluid needs to be purified. Purification is a crucial step in treating waste fluid containing oil, heavy metals, and organic pollutants generated during metal cutting, aiming to achieve compliant discharge or resource reuse. For example, a pretreatment device for cutting waste fluid, as disclosed in CN208454704U, includes a collection tank for collecting the cutting waste fluid, an adjustment tank for adjusting the pH value of the cutting waste fluid, a three-in-one reactor for electrolytic oxidation treatment of the cutting waste fluid, and a coagulation and sedimentation tank. The collection tank, the three-in-one electrolytic cell, and the coagulation sedimentation tank are connected sequentially from left to right in the order of wastewater treatment via pipelines. A first lift pump is installed on the pipeline connecting the collection tank and the equalization tank, and a second lift pump is installed on the pipeline connecting the equalization tank and the three-in-one reactor. The three-in-one electrolytic cell includes a rectangular tank body, an anode plate and two cathode plates disposed within the rectangular tank body. A first partition and a second partition are arranged from left to right in the rectangular tank body. The first partition and the second partition divide the inner cavity of the rectangular tank body into an electrocoagulation reaction zone, an electro-Fenton reaction zone, and a three-dimensional electrolysis reaction zone. The device can thoroughly demulsify cutting waste fluid and produce effluent with good biodegradability. For example, a cutting waste fluid filtration and separation device with announcement number CN215855591U includes a cabinet. A waste fluid tank for connecting to a waste fluid container is located on one side of the lower part of the cabinet. A boiler for heating the waste fluid is located on the upper part of the cabinet. The boiler is connected to the waste fluid tank via a suction pipe. A vacuum device is installed on the boiler to allow the waste fluid tank to pump liquid into the boiler. A steam outlet at the top of the boiler is connected to a condensation mechanism. A wastewater drain pipe is installed on the condensation mechanism, and a filtration mechanism is also installed on the suction pipe. This device is convenient for separating and treating cutting waste fluid, reducing subsequent treatment costs. However, the above-mentioned cutting fluid filtration and separation device still has the following disadvantages in actual use: 1. When separating solid impurities, traditional cutting fluid purification mechanisms are prone to adhering to the filter screen and are difficult to separate because the solid impurities contain liquid. This not only affects the removal of solid impurities but also affects the smooth flow of cutting fluid; 2. Furthermore, when filtering solid impurities, there is incomplete filtration, which affects the subsequent discharge of liquid and lacks a structure for secondary purification of cutting fluid.

[0003] To address the aforementioned issues, there is an urgent need for innovative designs based on existing cutting fluid purification mechanisms. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting fluid purification mechanism for casting processing, in order to solve the problems mentioned in the background art that traditional cutting fluid purification mechanisms easily adhere to the filter screen and are difficult to separate when filtering out solid impurities, and lack a structure for secondary purification of the cutting fluid.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cutting waste fluid purification mechanism for casting processing, comprising a purification tank, a slag removal box fixed to the top of the purification tank, and a servo motor mounted on the back of the slag removal box; further comprising: a slag removal mechanism disposed on the output shaft of the servo motor, the slag removal mechanism removing solid impurities from the cutting waste fluid by scooping; and an extraction mechanism disposed inside the purification tank, the extraction mechanism being used to draw air to accelerate the falling of scooped impurities, and the extraction mechanism can also be used to extract the cutting waste fluid for secondary filtration.

[0006] Preferably, the slag removal mechanism includes a movable frame fixed to the output shaft of a servo motor, and a filter screen is fixed inside the movable frame. The bottom of the filter screen is in contact with the inner bottom surface of the slag removal box. At the same time, a liquid outlet valve is provided at the bottom of the slag removal box, and the cutting waste liquid is separated into solid and liquid inside the slag removal box.

[0007] Preferably, the bottom of the slag removal box has an arc-shaped structure, and the center of the arc at the bottom of the slag removal box coincides with the rotation center of the servo motor output shaft. The rotation angle of the movable frame and the filter screen is less than 180°, and the movable frame drives the filter screen to swing to remove slag.

[0008] Preferably, the slag removal box is provided with slag outlets on both sides, and the interior of the slag removal box is connected to the collection box through the slag outlets. The collection box is symmetrically fixed on both sides of the slag removal box, and the dredged waste slag falls into the collection box through the slag outlets.

[0009] Preferably, the extraction mechanism includes a movable ring fixed to the bottom of the filter screen, and the movable ring and the slag removal box are slidably connected. The bottom of the movable ring and one end of the movable plate are rotatably connected. When the filter screen swings, it drives the movable ring to slide on the slag removal box.

[0010] Preferably, a connecting rod is rotatably provided at the other end of the movable plate, and a connecting plate is fixed at the bottom of the connecting rod. The connecting plate is in close contact with the inner bottom surface of the purification box. A liquid outlet is provided on the side of the purification box. When the movable ring rotates back and forth, it drives the movable plate to rotate, thereby driving the connecting rod to rise and fall.

[0011] Preferably, the upper end face of the connecting plate is fixedly connected to the bottom of the corrugated pipe, and a fixing plate is fixed to the top of the corrugated pipe. The fixing plate is fixed inside the purification box. At the same time, the connecting rod and the fixing plate are slidably connected. When the connecting rod rises, it drives the connecting plate to rise synchronously and squeezes the corrugated pipe.

[0012] Preferably, the side of the fixing plate is fixedly connected to one end of the hose, and the other end of the hose is connected to a gravity ball. The gravity ball is hollow, and the interior of the purification box is interconnected with the hose through the gravity ball. At the same time, the hose is connected to the corrugated pipe. When the corrugated pipe is compressed, the gas inside it can be transmitted to the interior of the movable frame through the transmission pipe.

[0013] Preferably, the back of the corrugated pipe is connected to the upper end of the movable frame through a transmission pipe, and the upper end of the movable frame is provided with a cavity. Both the transmission pipe and the flexible hose are provided with one-way valves. At the same time, the inner wall of the upper end of the movable frame is provided with fixing holes at equal angles. After the gas is discharged from the fixing holes, it can help the residue on the filter screen fall off.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the cutting fluid purification mechanism for casting processing can prevent impurities from adhering to the filter screen and being difficult to separate when filtering out solid impurities. It is equipped with a structure to assist in the rapid separation and falling of impurities, and can perform secondary filtration of the cutting fluid to avoid incomplete filtration and facilitate subsequent discharge of the cutting fluid. The specific contents are as follows: 1. A servo motor drives the movable frame and filter screen to swing back and forth, which can continuously scoop out solid impurities in the slag removal box. When the filter screen rotates to a position close to the slag outlet, the solid waste slag scooped out by the filter screen can fall into the collection box through the slag outlet from the inclined filter screen; 2. During the swinging process of the filter screen, the movable frame and filter screen are driven to swing back and forth. The synchronous rotation of the ring causes the movable ring to rotate, which in turn pulls the connecting rod up and down within the fixed plate. This causes the connecting plate to rise synchronously, compressing the corrugated pipe and forcing the gas inside to be transmitted through the transmission pipe to the cavity inside the movable frame. The gas is then discharged from the fixed hole and blown onto the filter screen surface, thus helping to expel solid impurities and facilitate their removal. 3. When there is waste liquid in the purification box, the liquid can be drawn into the hose through a gravity ball, then into the corrugated pipe, and then transmitted through the transmission pipe to the cavity of the movable frame. The waste liquid can then be discharged from the fixed hole and undergo secondary filtration through the filter screen. The discharged waste liquid also has a flushing effect on the filtered residue.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please refer to Figures 1-8. The present invention provides the following technical solution: Embodiment 1: In order to solve the problems existing in the prior art, this embodiment provides the following technical solution: a cutting waste fluid purification mechanism for casting processing, including a purification tank 1, a slag removal tank 2 fixed on the top of the purification tank 1, and a servo motor 3 installed on the back of the slag removal tank 2; it also includes: a slag removal mechanism, which is set on the output shaft of the servo motor 3, and the slag removal mechanism removes solid impurities in the cutting waste fluid by scooping; and an extraction mechanism, which is set inside the purification tank 1, and the extraction mechanism is used to draw air to accelerate the falling of the scooped impurities, and the extraction mechanism can also be used to extract the cutting waste fluid for secondary filtration.

[0019] Existing cutting fluid purification mechanisms, when separating solid impurities, often encounter difficulties because the solid impurities contain liquid, making them prone to adhering to the filter screen 5 and difficult to separate. This not only affects the removal of solid impurities but also the smooth flow of the cutting fluid. As shown in Figures 1-5 and 8, the slag removal mechanism includes a movable frame 4 fixed to the output shaft of the servo motor 3, with a filter screen 5 fixed inside the movable frame 4. The bottom of the filter screen 5 is in close contact with the inner bottom surface of the slag removal box 2. Meanwhile, the bottom of the slag removal box 2 is equipped with... The bottom of the slag removal box 2 has an arc-shaped structure, and the center of the arc at the bottom of the slag removal box 2 coincides with the rotation center of the output shaft of the servo motor 3. The rotation angle of the movable frame 4 and the filter screen 5 is less than 180°. Slag outlets 6 are provided on both sides of the slag removal box 2, and the interior of the slag removal box 2 is interconnected with the collection box 7 through the slag outlets 6. The collection box 7 is symmetrically fixed on both sides of the slag removal box 2. The cutting waste fluid to be purified is poured into the slag removal box 2, and then the servo motor 3 drives the movable frame 4 and the filter screen 5 to swing back and forth. During the swinging process, the filter screen 5 can scoop up solid waste in the slag removal box 2. When the filter screen 5 rotates to a position close to the slag outlet 6, the solid waste scooped up by the filter screen 5 can fall into the collection box 7 from the slag outlet 6. Through the back and forth swinging of the filter screen 5, the waste can be continuously cleaned. During the swinging process of the filter screen 5, the movable ring 8 rotates synchronously. When the movable ring 8 rotates, it drives the movable plate 9 to rotate, which in turn pulls the connecting rod 10 to rise and fall within the fixed plate 13. When the connecting rod 10 rises, it drives the connecting plate 11 to rise synchronously and squeezes the corrugated pipe 12. After squeezing, the gas inside is transmitted to the cavity inside the movable frame 4 through the transmission pipe 16, and then discharged from the fixed hole 17 and blown onto the surface of the filter screen 5. Therefore, when the filter screen 5 rotates to the sides to the tilted state, it can drive the gas to be discharged, which plays a role in assisting the solid impurities to fall and improving the slag removal efficiency. When the corrugated pipe 12 is not squeezed, it automatically returns to the expanded state. The gas can be drawn into the corrugated pipe 12 through the hose 14 by the gravity ball 15 for the next discharge.

[0020] Example 2: When filtering solid impurities from cutting fluid, incomplete filtration occurs, affecting subsequent liquid discharge. A structure for secondary purification of the cutting fluid is lacking. Therefore, this example addresses this issue with the following technical solution, as shown in Figures 5-8: The extraction mechanism includes a movable ring 8 fixed to the bottom of the filter screen 5, with the movable ring 8 and the slag removal box 2 slidably connected. The bottom of the movable ring 8 and one end of the movable plate 9 are rotatably connected. A connecting rod 10 is rotatably mounted on the other end of the movable plate 9, and a connecting plate 11 is fixed to the bottom of the connecting rod 10. The connecting plate 11 is fitted to the inner bottom surface of the purification box 1, and a liquid outlet is provided on the side of the purification box 1. The upper end of the connecting plate 11 is fixedly connected to the bottom of the corrugated pipe 12, and a fixing plate 13 is fixed to the top of the corrugated pipe 12. The fixing plate 13 is fixed inside the purification box 1, and the connecting rod 10 and the fixing plate 13 are slidably connected. The side of the fixing plate 13 is fixedly connected to one end of the hose 14, and a gravity ball 15 is connected to the other end of the hose 14. The gravity ball 15 is... The purification chamber 1 is hollow, and its interior is interconnected with a gravity ball 15 and a flexible hose 14. The flexible hose 14 is also connected to a corrugated pipe 12. The back of the corrugated pipe 12 is connected to the upper end of the movable frame 4 via a transmission pipe 16. The upper end of the movable frame 4 has an internal cavity, and both the transmission pipe 16 and the flexible hose 14 are equipped with one-way valves. The inner wall of the upper end of the movable frame 4 has fixing holes 17 at equal angles. After the cutting waste fluid is descaled, the waste fluid flows into the purification chamber 1, and the servo motor 3 continues to drive it. The movement causes the connecting rod 10 and the connecting plate 11 to rise and fall. At this time, the liquid in the purification box 1 can be drawn into the hose 14 through the gravity ball 15, and then into the corrugated pipe 12. Then it is transmitted to the cavity of the movable frame 4 through the transmission pipe 16. After that, the waste liquid can be discharged from the fixed hole 17 and filtered twice through the filter screen 5. The discharged waste liquid has a flushing effect on the filtered residue and can also prevent the residue from adhering to the filter screen 5. The purified waste liquid can be discharged directly or allowed to stand to achieve oil-water separation as needed.
