Description

Cutting and grinding fluid pre-coating bag filter device (Part 2)

The present invention relates to a filter device, specifically a cutting and grinding fluid pre-coating bag filter device used in metal processing operations.

In order to improve processing efficiency and reduce tool damage, processing machines (lathes, milling machines, grinders) will transfer the heat generated by the cutting of tools and workpieces to the cutting fluid during metal processing. In addition to reducing the high temperature cooling and lubrication effect generated during the processing, it can also increase the speed and feed rate during the processing process, thereby improving cutting efficiency, improving the surface accuracy and quality of the workpiece, and extending the service life of the tool.

However, during the cutting or grinding process, processing machines will inevitably generate more or less waste chips, and the coarseness of the waste chips varies with the type of processing. When the waste chips are generated, they will mix with the cutting fluid of the machine. Since the coolant is quite expensive, it must be filtered before recycling. In view of this, some manufacturers have developed a filter machine specifically for filtering cutting fluid. Since the waste chips generated by the grinder are quite fine, they cannot be filtered accurately and will be recycled with the cutting fluid, affecting the purity of the cutting fluid and indirectly affecting the precision of the processing.

In view of this, the inventor has been engaged in the manufacturing, development and design of related products for many years. After careful design and careful evaluation for the above-mentioned goals, he finally obtained this invention which is truly practical.

The inner mesh bag 23 is positioned against the step 216 of the outer mesh bucket 22. One end of the inner mesh bag 23 forms a bag opening 231 and is fixed with an annular frame 232. The end edge of the annular frame 232 is surrounded by a second lip 233. The inner wall of the annular frame 232 is symmetrically provided with two handles 234. The mesh diameter of the inner mesh bag 23 is smaller than the mesh diameter of the outer mesh bucket 22. The top end of the inner conduit 24 has a The plate 241 has an opening 242 connected to the inner conduit 24, and a U-shaped handle 243 is provided at the top of the plate 241. A cap 244 is provided at the bottom of the inner conduit 24. The cap 244 has a plurality of water outlet holes 245 in a scattered manner. The cap 25 is tightly fixed to the opening of the filter cylinder 20 with a tightening ring 251. 211, and an exhaust valve 252 is provided at the top of the cover 25, and the exhaust valve 252 is further provided with a pressure gauge 253; the pressurizing motor 30 is installed on the platform 11 of the base 10, and the pressurizing motor 30 is provided with an inlet 31 and an outlet 32, and the inlet 31 is connected to a first inlet valve 331 and a second inlet valve 332 through a three-way pipe 33, and the first inlet valve 331 and the second inlet valve 332 are connected to the first inlet valve 331 and the second inlet valve 332. An inlet valve 331 is connected to a premixing barrel 34, the second inlet valve 332 is connected to a cutting waste liquid pipe 35, the outlet 32 is connected to the inlet end 212 of the outer barrel 21 through an output pipe 321, and a filter material 40 is uniformly stirred through the premixing barrel 34 and then input into the filter cylinder 20 by the pressure motor 30, and attached to the inner side of the inner mesh bag 23.

The structure is shown in Figures 1 to 4. The outer cylinder body 21 of the filter cylinder 20 is sequentially inserted into the outer cylinder body 21 through the opening 211. The outer cylinder body 22 is positioned by abutting the first lip 222 against the step 216 of the limiting ring 215. The inner cylinder bag 23 is laid in the outer cylinder body 22, and the annular frame 232 is embedded in the inner diameter of the opening 221 of the outer cylinder body 22. The second lip 233 is abutted against the first lip 222 to form a fixed position. The plate 241 of the inner conduit 24 abuts against the limiting ring 215 and the top of the outer net barrel 22, and the inner conduit 24 is centered and inserted into the inner net bag 23. Finally, the cover 25 is matched with the tightening ring 251 to tightly close and fix the opening 211 of the filter cylinder 20. The first outlet valve 261 of the filter cylinder 20 is connected to a first recovery pipe 27 and communicated with the premix barrel 34. The second outlet valve 262 is connected to a second recovery pipe 28 to recover the filtered cutting and grinding fluid, thereby completing the cutting and grinding fluid pre-coating bag filtering device.

The structure is shown in Figures 1, 5 and 6. Before the filtering device performs filtering, a pre-coating step of the filter material 40 is performed. The filter material 40 is pre-coated on the inner side of the inner mesh bag 23. The filter material 40 is diatomaceous earth powder. When the filter material 40 is actually coated, the pressure motor 30 opens the first inlet valve 331 and The second inlet valve 332 is closed, and the outlet end 213 of the filter cartridge 20 opens the first outlet valve 261 and closes the second outlet valve 262. The filter material 40 powder and the cutting fluid are first fully stirred and mixed in the premixing barrel 34, and then the cutting fluid mixed with the filter material 40 is passed through the first inlet by the pressurized motor 30. After the valve 331 and the output pipe 321 are installed, the fluid is pressurized and inputted into the outer barrel 21 from the inlet end 212, and then enters from the opening 242 and is discharged downward along the bottom of the inner conduit 24, so that the cutting fluid mixed with the filter material 40 is gradually filled from bottom to top. At this time, since the inner side of the inner mesh bag 23 will first contact the cutting fluid and its filter material 40, the filter material 40 will adhere to the inner side of the inner mesh bag 23, and the cutting fluid will pass through the inner mesh bag 23 and the outer mesh barrel 22 and then be discharged from the outlet end 213, and then flow back to the pre-mix barrel 34 along the first recovery pipe 27, thereby forming a pre-coating circulation operation, and the filter material 40 is evenly attached to the inner side of the inner mesh bag 23.

When the structure performs filtering operation, as shown in FIGS. 7 and 8, the pressure motor 30 closes the first inlet valve 331 and opens the second inlet valve 332, and the outlet end 213 of the filter cartridge 20 closes the first outlet valve 261 and opens the second outlet valve 262. The cutting waste fluid generated by the workpiece cutting and grinding operation is introduced into the pressure motor 30 through the cutting waste fluid pipe 35 and the second inlet valve 332, and then is input into the filter cartridge 20 through the inlet end 212 for filtering after being pressurized. Since the inner and outer sides of the inner mesh bag 23 are uniform, the inner and outer sides of the inner mesh bag 23 are uniformly The filter material 40 is coated to form a filter layer with smaller pores, so that the iron chips, impurities and even fine chips produced by grinding contained in the cutting waste fluid cannot pass through, and are attached to the filter material 40 and retained in the inner mesh bag 23, so that the cutting waste fluid passing through the inner mesh bag 23 and the outer mesh barrel 22 can be filtered, ensuring that the filtered cutting fluid can reach the quality of recycling and reuse. The filtered cutting fluid is then discharged from the outlet end 213 and the second outlet valve 262, and then introduced into the cutting fluid circulation system of the cutting and grinding work machine along the second recovery pipe 28 for use.

In addition, the filter material 40 can also be wood pulp powder. When the workpiece to be cut or ground is a precious metal, the metal chips remaining on the filter material 40 can be burned by burning the filter material 40, and the metal chips can be left for recycling, which helps to reduce processing costs.

When the filter cartridge 20 is blocked by iron filings and impurities and the filter discharge volume gradually decreases, it means that the filter cartridge 20 needs to be backwashed and cleaned. When the filter cartridge 20 is actually cleaned, please refer to Figures 9 and 10. The air inlet valve 214 of the outer cylinder body 21 is first connected to a high-pressure gas, and then the exhaust valve 252 is closed and the air inlet valve 214 is opened. The high-pressure gas is introduced into the filter cartridge 20 for drying, so that the inner mesh bag The residual cutting waste water in 23 can be squeezed out, and the inner mesh bag 23 is further dried. Then the air inlet valve 214 is closed and the exhaust valve 252 is opened to release the gas pressure in the filter cylinder 20, and the internal pressure value is confirmed by the pressure gauge 253. Finally, the cover 25 can be removed to take out the inner mesh bag 23, and the inner mesh bag 23 can be cleaned or replaced to complete the backwash cleaning operation of the filter cylinder 20.

Furthermore, after the filtration operation, some impurities and dirt will be deposited at the bottom of the filter cylinder 20. At this time, the cleaning pipe 217 at the bottom of the outer cylinder body 21 can be opened and flushed with water, as shown in Figure 11, to discharge the impurities and dirt from the cleaning pipe 217, thereby achieving the purpose of cleaning the inside of the filter cylinder.

The structure of the above-mentioned specific embodiment can achieve the following benefits: The present invention is to install the inner mesh bag 23 in the filter cylinder 20, and then pre-input the filter material 40 into the filter cylinder 20 through the pressure motor 30 and coat and attach it to the inner side of the inner mesh bag 23, so that the inner mesh bag 23 has a filter layer with smaller pores, which can indeed block the iron chips, impurities and even fine chips in the cutting waste fluid from passing through, greatly improve the filtering effect of the cutting waste fluid, ensure the quality of the cutting waste fluid for recycling and reuse, and have processing precision, thereby effectively reducing the operating cost.

In addition, since the iron chips and impurities in the waste cutting fluid are blocked during the filtering process and retained in the inner mesh bag 23, when the filter cylinder 20 needs to be backwashed, the backwashing of the filter cylinder 20 can be completed by simply taking out the inner mesh bag 23 for cleaning or replacing, which helps to reduce the cost and time of the backwashing process, so that the filter cylinder 20 can quickly continue the filtering process, thereby improving work efficiency.

In summary, this invention has indeed achieved a breakthrough structural design and has improved invention content. At the same time, it can achieve industrial applicability and progress. Moreover, this invention has not been seen in any publication and is also novel. It should comply with the relevant provisions of the Patent Law. Therefore, we have filed an invention patent application in accordance with the law and pleaded with the review committee of the Jun Bureau to grant legal patent rights. We are very grateful.
