Description

Technical Field

[0001] This utility model relates to the field of CNC machining equipment technology, and in particular to a CNC machining center for separating waste liquid and solid waste. Background Technology

[0002] CNC machining centers play a vital role in modern manufacturing. During metal cutting and other machining processes, cutting fluid is used for lubrication and cooling. After machining, a large amount of waste cutting fluid mixed with solid waste such as metal chips and abrasives is generated. In order to recycle and reuse the cutting fluid and properly dispose of the solid waste, it is usually necessary to use a special device to separate the solid and liquid components of this mixture.

[0003] Existing separation devices typically use negative pressure adsorption to draw waste liquid from the collection tank of the processing center into the filtration equipment. However, in actual operation, especially when dealing with waste liquid after a period of downtime, denser solid waste such as metal shavings will settle and accumulate at the bottom of the collection tank.

[0004] When the suction nozzle comes into contact with these high-concentration precipitates, it becomes clogged, causing adsorption to be interrupted. This not only severely reduces the processing efficiency but also requires frequent manual cleaning of the suction nozzle, increasing the complexity and labor intensity of the operation. Even if the waste liquid mixture is successfully sucked in, the high-speed liquid flow will splash everywhere during the process of spraying from the pipe onto the filter screen, causing pollution on the inner wall of the equipment, which is difficult to clean. At the same time, solid waste tends to accumulate in the center of the filter screen, forming local blockages, making most of the filter screen area unusable and further affecting the overall separation efficiency.

[0005] Therefore, this utility model proposes a CNC machining center for separating waste liquid and solid waste to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problem in the existing technology that the suction port of the suction tube of the CNC machining center for waste liquid-solid waste separation is blocked by the precipitated solid waste residue when suctioning waste liquid, resulting in interruption of separation work and low efficiency, this utility model aims to provide a CNC machining center for waste liquid-solid waste separation with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a CNC machining center for separating waste liquid and solid waste, including a machine body, a cover plate on the top of the machine body, and a conical filter screen fixed inside the machine body; the CNC machining center also includes a slag suction pipe, an anti-clogging mechanism connected to the liquid suction end of the slag suction pipe, and an anti-stacking mechanism fixed to the lower surface of the cover plate.

[0008] The anti-clogging mechanism includes a fixed ring that can rotate around the axis of the sludge suction pipe. The top of the fixed ring is provided with a protruding part, and the liquid suction end of the sludge suction pipe is provided with a corresponding annular groove. The protruding part is embedded in the annular groove, and the gap between the two is filled with balls. An inclined plate is fixedly connected to the inner circumference of the fixed ring, a scraper is fixedly connected to the bottom, and a guide plate is also fixedly connected to the fixed ring.

[0009] Furthermore, the inlet end of the slag suction pipe extends through the cover plate into the machine body, and the anti-stacking mechanism is located directly below the inlet end of the slag suction pipe and directly above the conical filter screen. The anti-stacking mechanism includes a baffle and a diversion plate fixed inside the baffle by a support rod.

[0010] Preferably, the anti-clogging mechanism is connected to the liquid suction end of the sludge suction tube via an elastic tube. The elastic tube is designed as a composite structure with an elastic upper part and a rigid lower part. This design provides effective buffer protection when the anti-clogging mechanism collides accidentally with the outside, thereby improving the overall durability of the device.

[0011] Preferably, the cover plate has a threaded groove, and the baffle of the anti-stacking mechanism is detachably fixed to the lower surface of the cover plate by screwing screws into the threaded groove. This connection method greatly simplifies the disassembly and installation process of the anti-stacking mechanism and provides convenience for subsequent cleaning and maintenance work.

[0012] Preferably, the conical filter screen has an inverted conical structure with an upper opening diameter larger than a lower opening diameter. The structure utilizes gravity to actively guide solid waste falling onto the screen surface to slide down and disperse along the inclined screen wall, effectively preventing excessive accumulation of solid waste in the center of the filter screen.

[0013] Preferably, the inclined plate is a plate body that is inclined along the circumference of the fixed ring. This inclined arrangement can make fuller use of the impact force generated by the adsorption liquid flow, which will be converted into a torque to drive the fixed ring to rotate, ensuring that the anti-clogging mechanism can work stably and continuously.

[0014] Preferably, the baffle is a hollow cap-like structure with an open top, which acts like a flow guide and can effectively confine the high-speed waste liquid flowing from the suction pipe inside the cylinder, preventing the liquid from splashing irregularly in all directions, thereby keeping the inside of the machine clean.

[0015] Preferably, the scraping edge of the scraper is inclined toward the rotation direction of the fixed ring. This inclination angle design allows the scraper to scoop up and push away the waste residue adhering to the bottom of the cutting fluid pool with a better cutting posture when rotating, thereby improving the cleaning ability of the settled solid waste.

[0016] Preferably, the support rod is arranged in a horizontal direction, and the diversion plate is a conical structure with the cone apex facing the inlet end of the sludge suction pipe, which can accurately guide the falling liquid flow to all sides, so as to achieve uniform diversion of waste liquid before it falls onto the conical filter screen.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem of the suction tube being blocked by precipitated solid waste and the low adsorption efficiency in the prior art by setting an anti-clogging mechanism driven by liquid flow, and using guide plates and scrapers to stir and scrape off waste residue simultaneously during liquid suction. It prevents clogging and improves adsorption efficiency.

[0018] 2. This utility model solves the problems of waste liquid splashing causing difficulty in cleaning equipment and solid waste accumulating in the center of the filter screen affecting filtration efficiency in the prior art by setting up an anti-splashing and diversion mechanism, and using an inverted conical filter screen. It achieves solid-liquid separation quickly and cleanly.

[0019] 3. This utility model solves the problem of damage when the liquid suction device collides rigidly with the workpiece or liquid pool in the prior art by using an elastic tube to connect the slag suction pipe and the anti-clogging mechanism. It buffers the impact, protects the components, and thus improves the reliability and service life of the equipment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1 to 4 This utility model provides a CNC machining center for separating waste liquid and solid waste, aiming to solve the problems in the prior art where the suction tube is blocked by solid waste when the waste liquid is sucked up, and the waste liquid splashes and accumulates on the filter screen when filtering, affecting efficiency.

[0024] like Figure 1 and Figure 3 As shown, a CNC machining center for separating waste liquid and solid waste includes a machine body 1. The top of the machine body 1 is covered by a cover plate 5. A conical filter screen 6 is fixed inside the machine body 1. The inlet end of the suction pipe 2 passes through the cover plate 5 and extends into the machine body 1. The structure together constitutes the basic framework for waste liquid containment and filtration. The structure of the CNC machining center for separating waste liquid and solid waste includes an anti-clogging mechanism 3 connected to the liquid suction end of the suction pipe 2, and an anti-stacking mechanism 4 fixed to the lower surface of the cover plate 5. Specifically, the anti-clogging mechanism 3 is used to agitate and scrape at the source of the adsorbed waste liquid. The structure includes a fixed ring 301 that can rotate around the axis of the suction pipe 2. In order to achieve smooth rotation, a protruding part is integrally formed on the top of the fixed ring 301. A corresponding annular groove 305 is opened at the liquid suction end of the suction pipe 2. The protruding part is embedded in the annular groove 305 to form a rotational fit. Multiple balls 306 are filled in the gap between the protruding part and the annular groove 305 to reduce rotational friction. Multiple inclined plates 302 are fixedly connected to the inner circumferential surface of the fixed ring 301 to provide rotational driving force when the waste liquid flows. A scraper 307 is fixedly connected to the bottom edge of the fixed ring 301. At the same time, a guide plate 303 is also fixedly connected to the fixed ring 301. The scraper 307 and the guide plate 303 rotate together with the fixed ring 301. The anti-stacking mechanism 4 is used to guide and prevent splashing of the waste liquid entering the machine body 1. It is fixed to the lower surface of the cover plate 5 and is positioned directly below the inlet end of the sludge suction pipe 2 and above the conical filter screen 6. The main body of the anti-stacking mechanism 4 is a baffle 402. Inside the baffle 402, a diversion plate 405 is fixedly connected by a support rod 404.

[0025] Please refer to Figure 1 and Figure 3To protect the equipment in the complex machining center environment, the slag suction pipe 2 and the anti-clogging mechanism 3 are connected by an elastic tube 304. One end of the elastic tube 304 is fixedly connected to the liquid suction end of the slag suction pipe 2, and the other end is rotatably connected to the main body of the anti-clogging mechanism 3, namely the fixed ring 301, through the cooperation of the annular groove 305 and the ball 306. The elastic tube 304 itself is designed as a composite structure with an elastic upper part and a rigid lower part. This structural design allows the upper elastic section to bend and deform to absorb and buffer the impact energy when the bottom scraper 307 of the anti-clogging mechanism 3 accidentally collides with the bottom or wall of the cutting fluid pool during the liquid suction process. This effectively protects the precision rotating structure of the anti-clogging mechanism 3 and the slag suction pipe 2 itself from damage caused by rigid impact, significantly improving the reliability and service life of the device. Please refer to Figure 3 and Figure 4 To facilitate regular cleaning and maintenance of the conical filter 6 and anti-stacking mechanism 4 inside the body 1, a threaded groove 401 is provided on the lower surface of the cover plate 5 at the installation position of the anti-stacking mechanism 4. The baffle 402 of the anti-stacking mechanism 4 has a mounting flange at the corresponding position, and a through hole is provided on the mounting flange. The screw 403 passes through the through hole and is screwed into the threaded groove 401 of the cover plate 5, thereby realizing a detachable fixed connection between the baffle 402 and the cover plate 5. This connection method through the screw 403 and the threaded groove 401 allows the operator to easily remove the entire anti-stacking mechanism 4 as a whole from the cover plate 5 when cleaning is required, simply by unscrewing the screw 403, which greatly simplifies the maintenance steps and reduces the difficulty of cleaning.

[0026] As a preferred embodiment, in order to further improve filtration efficiency and effectively prevent the concentrated accumulation of solid waste in the center of the filter screen, please refer to... Figure 3 The cone-shaped filter screen 6 is specially designed with an inverted cone structure, with the upper opening diameter being larger than the lower opening diameter. This shape, which is wider at the top and narrower at the bottom, allows waste liquid and solid residue to fall naturally along the inclined mesh surface and disperse under the action of gravity when they fall on the filter screen, avoiding local accumulation at the center point and thus ensuring the effective utilization of the entire filter screen area. As another preferred embodiment, to ensure that the anti-clogging mechanism 3 can obtain a stable and effective rotary driving force, please refer to... Figure 2 The inclined plate 302 on the inner circumference of the fixed ring 301 is designed as a plate body inclined along the circumference of the fixed ring 301. When the waste liquid is adsorbed by negative pressure and flows upward, the liquid flow will continuously impact the surface of these inclined plates, thereby generating tangential force. The force acts on the fixed ring 301 to form a rotational torque, driving stable rotation. As another preferred embodiment, in order to effectively contain splashes and guide the liquid flow, please refer to... Figure 4The baffle 402 in the anti-stacking mechanism 4 is designed as a hollow cover-shaped structure with an open top. The waste liquid sprayed at high speed from the inlet end of the slag suction pipe 2 first enters the interior of the cylindrical structure. The splash direction is effectively limited by the cylinder wall, thus avoiding the waste liquid from contaminating the cover 5 and the inner wall of the body 1. For better scraping results, please refer to... Figure 2 The scraper 307 at the bottom of the anti-clogging mechanism 3 has its scraping blade tilted towards the rotation direction of the fixed ring 301. This design allows the scraper 307 to scoop up and push away the sediment and waste residue adhering to the bottom of the cutting fluid pool at a better cutting angle when it rotates, thus improving cleaning efficiency. For further optimization of the internal structure of the anti-stack mechanism 4, please refer to Figure 4 The support rod 404 used to fix the diversion plate 405 is set in the horizontal direction, and the diversion plate 405 itself is preferably a conical structure, with the cone tip of the diversion plate 405 facing the inlet end of the slag suction pipe 2. In this way, the liquid flow falling from above will first impact the cone tip, and then spread evenly in all directions along the cone surface, thus achieving efficient diversion.

[0027] Working principle: When the CNC machining center finishes its work and starts the waste liquid adsorption program, the suction pipe 2 generates negative pressure, drawing the cutting fluid mixed with solid waste from the suction end. As the waste liquid flows upward, it continuously impacts the inclined plate 302 on the inner circumference of the fixed ring 301 on the anti-clogging mechanism 3. Since the inclined plate 302 is set at an inclination, the impact force of the liquid flow generates a rotational torque, driving the fixed ring 301 to rotate together with the externally fixed guide plate 303 and scraper 307. With the assistance of the ball bearing 306, the rotation process is smooth and stable. The rotation of the guide plate 303 agitates the waste liquid at the bottom of the waste liquid pool, causing the precipitated solid waste to be suspended. Meanwhile, the scraper 307 scrapes off the solid waste adhering to the bottom of the pool. The two work together to effectively prevent the solid waste from accumulating at the suction inlet and causing blockage. After passing through the suction pipe 2, the waste liquid flows out from the inlet end located inside the machine body 1. It first enters the internal space of the baffle 402 in the anti-stacking mechanism 4, where the splashing direction is effectively limited. Subsequently, the waste liquid impacts the cone top of the diversion plate 405 below and spreads evenly around the cone surface of the diversion plate 405. Then, it falls evenly on the entire surface of the cone-shaped filter screen 6. Since the cone-shaped filter screen 6 has an inverted cone structure, the solid waste will slide down the screen wall to the bottom of the machine body 1 for collection under the action of gravity, while the filtered cutting fluid falls through the filter screen into the bottom of the machine body 1, thus achieving efficient solid-liquid separation.
