Description

Technical Field

[0001] This utility model relates to the technical field of cutting fluid circulating ring filtration, specifically a milling machine cutting fluid circulating filtration system. Background Technology

[0002] A milling machine is a machine tool that uses a milling cutter to machine various surfaces of a workpiece. The milling cutter typically uses rotation as its primary motion, while the movement of the workpiece and the cutter constitutes the feed motion. It can machine planes, grooves, various curved surfaces, gears, etc. Besides milling planes, grooves, gear teeth, threads, and splined shafts, milling machines can also machine relatively complex profiles. They are more efficient than planers and are widely used in mechanical manufacturing and repair departments. Cutting fluid is an industrial liquid used in metal cutting, grinding, and machining processes to cool and lubricate cutting tools and workpieces. To reduce resource consumption, existing methods typically involve filtering and recycling cutting fluids to achieve recycling and reduce consumption. However, with conventional filtration devices, filter residue often accumulates on the surface of the filter screen after filtration, easily causing clogging. Furthermore, cleaning the filter residue usually requires disassembly of the device, which is time-consuming and labor-intensive. Utility Model Content

Detailed Implementation

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example: Figure 1 , Figure 2 , Figure 3 As shown, this utility model discloses a milling machine cutting fluid circulation filtration system, including a solid-liquid separator 1, a buffer tank 2, a fine filter 3, and a storage tank 4. The outlet end of the solid-liquid separator 1 is connected to the buffer tank 2. The buffer tank 2 is connected to the inlet end of the fine filter 3 via a liquid delivery pump. The outlet end of the fine filter 3 is connected to the storage tank 4. The storage tank 4 is connected to the cooling head via a delivery pump.

[0022] The fine filter 3 includes a filter housing 5. The bottom of the filter housing 5 has a downward-facing drain pipe 6. A filter screen 7 is installed inside the filter housing 5, and a filter chamber is formed between the bottom of the filter screen 7 and the bottom of the filter housing 5. The filter housing 5 has an inlet pipe 8 communicating with its interior, and an outlet pipe 9 is located on the side wall of the filter housing 5 above the filter screen 7. A switch valve 14 is located at the bottom of the drain pipe 6, and the bottom of the filter housing 5 is made of transparent material. By placing the filter chamber below the filter screen 7 and the outlet pipe 9 above the filter screen 7, the cutting waste fluid flows from bottom to top through the filter screen 7. This allows the filtered residue to easily fall to the bottom of the filter chamber under its own gravity, preventing it from accumulating on the surface of the filter screen 7 and clogging the mesh.

[0023] The filter housing 5 has an annular outlet pipe 10 below the filter screen plate 7, and the annular outlet pipe 10 has a water outlet hole 11 facing the bottom surface of the filter screen plate 7, and the water outlet hole 11 is flush with the bottom surface; in addition, the filter housing 5 has an annular outlet pipe 10 below the filter screen plate 7, and the annular outlet pipe 10 has a water outlet hole 11 facing the bottom surface of the filter screen plate 7. In this way, during the liquid inlet process, liquid flow is generated, which achieves a certain cleaning effect on the surface of the filter screen plate 7 and avoids the accumulation of filter residue.

[0024] The filter housing 5 is provided with a horizontally arranged connecting pipe 12 at the bottom, and an electromagnetic adsorption tube 13 is installed internally on the connecting pipe 12. This allows the electromagnetic adsorption tube 13 to extend into the filter chamber, adsorbing ferrous debris while preventing filter residue from flowing around and clogging the mesh.

[0025] The filter housing 5 is cylindrical, and a top cover 15 is threaded onto the top of the filter housing 5. A vertically downward central shaft 16 is provided at the center of the top cover 15, and a filter screen frame 17 that moves along the inner cavity of the filter housing 5 is mounted on the bottom of the central shaft 16 via a bearing. The filter screen plate 7 is mounted on the filter screen frame 17, which facilitates the disassembly of the filter screen frame.

[0026] The filter frame 17 is provided with a sealing ring 18 on its periphery to seal the connection between the filter frame 17 and the inner wall of the filter housing 5, which has a good sealing effect.

[0027] The bottom of the filter housing 5 is a downwardly recessed arched structure, which facilitates the entry of filter residue into the discharge pipe 6 and makes it easier to discharge.

[0028] Working principle: This milling machine cutting fluid circulation filtration system sets the filter chamber below the filter screen plate 7 and the outlet pipe 9 above the filter screen plate 7. This allows the cutting fluid to flow from bottom to top through the filter screen plate 7. The filtered residue easily falls to the bottom of the filter chamber under its own gravity, preventing it from accumulating on the surface of the filter screen plate 7 and clogging the mesh. Furthermore, the filter housing 5 has an annular outlet pipe 10 below the filter screen plate 7, with water outlet holes 11 facing the bottom surface of the filter screen plate 7. During the fluid inlet process, the fluid flows, effectively cleaning the surface of the filter screen plate 7 and preventing the accumulation of filter residue.
