Description

Technical Field

[0001] This utility model relates to the field of wastewater recycling technology for metal grinding machines, and in particular to a wastewater recycling device for metal grinding processing. Background Technology

[0002] In the metalworking industry, grinding, polishing, and cutting are common surface treatment methods. During these processes, to reduce the surface temperature of the workpiece, minimize dust dispersion, and improve processing efficiency, water-based coolants or lubricants are typically used for spraying or rinsing. However, these liquids mix with large amounts of metal powder, abrasive particles, oil, and other processing residues during use, forming highly polluting and high-load wastewater.

[0003] Existing factories generally use centralized discharge or sedimentation tanks for coarse treatment of this type of wastewater. However, this method has obvious drawbacks: on the one hand, the sedimentation process is slow, occupies a large space, and has low treatment efficiency; on the other hand, if the unfiltered wastewater is directly recycled, it can easily lead to problems such as cooling system blockage, nozzle wear, and workpiece contamination, affecting the quality of subsequent processing and the life of equipment. Utility Model Content

[0004] Based on this, it is necessary to address the common practice in existing factories of centralized discharge or coarse treatment in sedimentation tanks to handle this type of wastewater. However, this approach has significant drawbacks: on the one hand, the sedimentation process is slow, requires a large space, and has low treatment efficiency; on the other hand, if unfiltered wastewater is directly recycled, it can easily lead to problems such as cooling system blockage, nozzle wear, and workpiece contamination, affecting subsequent processing quality and equipment lifespan. Therefore, a metal grinding wastewater recycling device is provided. This device includes: a grinding machine, with a recycling tank fixedly installed at the bottom of the grinding machine, and multiple support legs fixedly installed at the bottom of the grinding machine; a wastewater recycling mechanism, used to recycle and reuse the processing wastewater from the metal grinding machine, located inside the recycling tank; wherein the wastewater recycling mechanism includes a guide frame fixedly installed on the top of the recycling tank, a first guide plate fixedly installed inside the guide frame, a filter assembly at the bottom of the first guide plate, and a circulation assembly on the inner wall of the recycling tank.

[0005] The filter assembly includes a second guide plate disposed at the bottom of the first guide plate. The top of both the first and second guide plates is sloping. Both the first and second guide plates are fixedly installed inside the guide frame. A movable frame is disposed at the bottom of the first guide plate. Multiple magnetic plates are disposed at the bottom of each movable frame. The multiple magnetic plates are in contact with the surface of the second guide plate.

[0006] Both sides of the plurality of magnetic plates are set as inclined surfaces, and an elastic telescopic rod is fixedly installed on the top of the magnetic plates. The top ends of the plurality of elastic telescopic rods are fixedly connected to the bottom of the movable frame.

[0007] A water guide frame is fixedly installed on one side of the second guide plate, and a filter element is slidably installed inside the water guide frame.

[0008] The movable frame is slidably connected to the bottom of the first guide plate. A pull rod is fixedly installed on one side of both the movable frame and the filter element, and the pull rod is sealed and snapped into the recycling bin.

[0009] The circulation assembly includes a circulation pump fixedly installed inside the recycling bin. A suction pipe and an output pipe are fixedly installed on both sides of the circulation pump, and one end of the suction pipe extends to the bottom of the recycling bin.

[0010] The other end of the inhalation tube is fixedly connected to a filter head, which is cylindrical in shape.

[0011] The filter head is sealed and snapped into the suction tube, and the magnetic plate and the elastic telescopic rod are connected to each other by threads.

[0012] Beneficial effects

[0013] 1. By setting up a guide frame and its internal first guide plate, the wastewater generated during the grinding process can be guided to the filter assembly for preliminary filtration under gravity, avoiding large particles of impurities from impacting the filter element and causing blockage. The clean water after preliminary purification is drawn out by the circulation component set on the inner wall of the recovery tank and sent back to the cooling system of the grinder, realizing a closed-loop circulation process of filtration, recirculation, and reuse.

[0014] 2. A cylindrical filter head is fixedly attached to the end of the suction pipe to provide further end protection for the filtrate at the bottom of the recovery tank, preventing residual impurities, incompletely settled fine particles, or larger particles from being sucked into the circulation pump with the water flow.

[0028] The following is combined with Figures 1-4 This invention describes a wastewater recovery device for metal grinding and processing.

[0029] In one embodiment, a metal grinding wastewater recycling device includes: a grinding machine 100, a recycling tank 200 fixedly installed at the bottom of the grinding machine 100, and multiple support legs 110 fixedly installed at the bottom of the grinding machine 100; a wastewater recycling mechanism 300, which is disposed inside the recycling tank 200 for recycling the processing wastewater of the metal grinding machine 100; wherein the wastewater recycling mechanism 300 includes a guide frame 310 fixedly installed at the top of the recycling tank 200, a first guide plate 311 fixedly installed inside the guide frame 310, a filter assembly 320 disposed at the bottom of the first guide plate 311, and a circulation assembly 330 disposed on the inner wall of the recycling tank 200.

[0030] In this embodiment, by setting the guide frame 310 and its internal first guide plate 311, the wastewater generated during the metal grinding process can be effectively guided to the filter assembly 320 under the action of gravity, and the wastewater can be directly filtered to prevent larger particles from directly impacting the filter element and causing blockage or damage. This achieves stable, continuous, and preliminary purification treatment of the grinding wastewater. The circulation assembly 330 set on the inner wall of the recycling tank 200 can re-extract the filtered water and transport it to the cooling circuit of the grinding machine 100, realizing a closed-loop cycle of filtration-re-extraction-reuse.

[0031] It should be noted that the existing metal grinding machine 100 typically includes basic components such as a grinding host, drive motor, grinding wheel mechanism, operating table, and coolant spray device. Both the filter assembly 320 and the circulation assembly 330 are located inside the recovery tank 200 below the grinding machine 100. The filter assembly 320 is positioned along the guide path to filter impurities in the returned wastewater multiple times, without direct contact with the main drive system of the grinding machine 100. The circulation assembly 330 is arranged along the inner wall of the recovery tank 200, forming an independent water system. It is only responsible for extracting and returning purified water, without occupying the processing space, movement space, or operating area of ​​the grinding machine 100, nor interfering with its original cooling spray system and main circuit structure, and will not affect the normal operation of the metal grinding machine 100.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, the filter assembly 320 includes a second guide plate 322 disposed at the bottom of the first guide plate 311. The tops of both the first guide plate 311 and the second guide plate 322 are sloped. Both the first guide plate 311 and the second guide plate 322 are fixedly installed inside the guide frame 310. A movable frame 321 is disposed at the bottom of the first guide plate 311. Multiple magnetic plates 324 are disposed at the bottom of each movable frame 321. The multiple magnetic plates 324 are in contact with the surface of the second guide plate 322.

[0033] In this embodiment, the first guide plate 311 and the second guide plate 322 are inclined at the top, which allows the wastewater generated during the metal grinding process to flow quickly along the inclined surface under the action of gravity and be concentrated in the filtration area, thereby improving the wastewater guiding efficiency. Multiple magnetic plates 324 can simultaneously adsorb magnetic particles such as metal chips and iron powder mixed in the wastewater during the wastewater flow, realizing the on-site recovery of magnetic impurities. This not only improves the purification efficiency of the filter component 320, but also reduces the risk of filter element clogging.

[0034] Both sides of the multiple magnetic plates 324 are set as inclined surfaces, and the top of the magnetic plates 324 is fixedly installed with elastic telescopic rods 323. The top of the multiple elastic telescopic rods 323 are fixedly connected to the bottom of the movable frame 321.

[0035] In this embodiment, by setting the two sides of the multiple magnetic plates 324 as inclined structures, it helps to form a controllable flow path when the wastewater flows through the surface of the magnetic plates 324, causing impurities to concentrate in the middle and be magnetically adsorbed, thereby improving the capture efficiency of magnetic particles such as iron filings and metal powders. The multiple elastic telescopic rods 323 fixedly connected to the top of the magnetic plates 324 can make the magnetic plates 324 slightly press down due to gravity after adsorbing too many impurities, and maintain stable contact with the surface of the second guide plate 322 through the elastic buffer mechanism, and automatically reset when the moving frame 321 is pulled out.

[0036] A water guide frame 325 is fixedly installed on one side of the second guide plate 322, and a filter element 326 is slidably installed inside the water guide frame 325.

[0037] In this embodiment, by fixing a water guide frame 325 on one side of the second guide plate 322, the water flow can be guided in a standardized manner after the wastewater passes through the magnetic adsorption area, so that the wastewater can stably enter the filter element 326 for deep filtration treatment.

[0038] The movable frame 321 is slidably connected to the bottom of the first guide plate 311. A pull rod 327 is fixedly installed on one side of both the movable frame 321 and the filter element 326. The pull rod 327 is sealed and snapped into the recycling box 200.

[0039] In this embodiment, both the movable frame 321 and the filter element 326 are provided with a pull rod 327 on one side, and a sealed snap-fit ​​structure is formed between them and the recycling bin 200. This not only makes it convenient to pull out the corresponding parts directly from the outside of the bin for replacement and cleaning, but also ensures that no wastewater leakage or odor overflow occurs during the pulling and use process.

[0040] like Figure 2 , Figure 3 and Figure 5 As shown, the circulation assembly 330 includes a circulation pump 331 fixedly installed inside the recycling bin 200. A suction pipe 332 and an output pipe 333 are fixedly installed on both sides of the circulation pump 331, and one end of the suction pipe 332 extends to the bottom of the recycling bin 200.

[0041] In this embodiment, one end of the suction pipe 332 extends to the bottom of the recovery tank 200, which can fully extract the filtered clean water that has settled at the bottom, avoiding the problem that the purified water cannot be fully utilized due to the residual height, and improving the utilization rate of the water tank. The output pipe 333 delivers the water stably, which helps to form a stable pressure output and ensures a continuous water supply for the spraying or rinsing system of the grinder 100.

[0042] The other end of the suction tube 332 is fixedly connected to a filter head 334, which is cylindrical in shape.

[0043] In this embodiment, a cylindrical filter head 334 is fixedly snapped to the end of the suction pipe 332. This provides further end protection for the filtrate located at the bottom of the recovery tank 200, preventing residual impurities, incompletely settled fine particles, or larger particles from being sucked into the circulation pump 331 along with the water flow. The filter head 334 adopts a cylindrical structure design, which has good structural stability and fluid permeability. While ensuring the filtration effect, it is not prone to adsorption dead zones due to water pressure deviation or sediment accumulation. This structure allows for circumferential water intake, improving pump suction efficiency.

[0044] The filter head 334 is sealed and snapped into the suction tube 332, and the magnetic plate 324 and the elastic telescopic rod 323 are connected to each other by threads.

[0045] In this embodiment, the magnetic plate 324 and the elastic telescopic rod 323 are connected by threads, so that the magnetic plate 324 can be disassembled and replaced by the operator by screwing after it is saturated with impurities, which is convenient for deep cleaning. By adopting a sealed snap-fit ​​structure between the filter head 334 and the suction pipe 332, the filter head 334 can be replaced or cleaned without disassembling the suction pipe 332.

[0046] Working Principle: During operation, the cooling wastewater generated by the metal grinder 100 flows into the recovery tank 200 from the bottom. Guided by the guide frame 310 and its internal inclined first guide plate 311 and second guide plate 322, the wastewater slides down the inclined surface and flows into the filtration area. Multiple magnetic plates 324 are installed on the movable frame 321 at the bottom of the first guide plate 311. The magnetic plates 324 are threaded to the elastic telescopic rod 323 and adhere to the surface of the second guide plate 322. They adsorb magnetic impurities such as iron filings and metal powder as the wastewater flows through, achieving preliminary purification. The wastewater further flows into the water guide frame 325 on one side of the second guide plate 322 and enters the filter element 326 slidably installed therein for deep filtration. Both the movable frame 321 and the filter element 326 are sealed and engaged with the recovery tank 200 by a pull rod 327, facilitating external removal for cleaning and replacement. The filtered water settles at the bottom of the recovery tank 200 and is drawn in by the circulation pump 331 through the suction pipe 332. The end of the suction pipe is equipped with a cylindrical filter head 334 with a sealing snap-fit ​​design to prevent clogging. The purified water is returned to the cooling system of the grinder 100 through the output pipe 333, forming a stable closed-loop recycling system.

[0047] It should be noted that the grinding machine and circulating pump mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the grinding machine and circulating pump can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
