Description

Technical Field

[0001] This utility model relates to the field of grinding fluid circulation supply and filtration technology, and in particular to a filtration component and a grinding fluid circulation supply device. Background Technology

[0002] In the field of machining, polishing slurry, as an important auxiliary material, is widely used in various grinding and polishing processes, playing a crucial role in improving machining accuracy and surface quality. During the use of polishing slurry, grinding operations generate a large amount of metal residue, abrasive particles, and other impurities. These impurities, when mixed into the polishing slurry, can severely affect its performance, reduce grinding efficiency, and may even cause wear on processing equipment. Therefore, to ensure the stable performance of the polishing slurry and extend its service life, the circulating supply of polishing slurry needs to be filtered to remove impurities.

[0003] Currently, various grinding fluid filtration devices exist on the market, such as the one disclosed in publication number CN221815417U. This device includes a housing, with an inlet pipe and an outlet pipe respectively connected to the top and bottom walls of the housing. Multiple pairs of first through grooves are formed on opposite side walls of the housing, and a filter assembly is slidably disposed within each pair of first through grooves. Each filter assembly includes a pair of filter plates, a pair of filter cloths, a pair of first sealing strips, and a pair of second sealing strips. The side walls of opposite sides of the pair of filter plates are interconnected, and each filter plate has a first groove. This device uses a pair of filter plates alternately; while cleaning one filter plate, the other can still filter. Furthermore, cleaning only requires removing the filter cloth, which removes the residue along with the filter cloth, thus improving filtration efficiency and reducing personnel workload to some extent.

[0004] However, the aforementioned existing technologies use gravity filtration, relying on the grinding fluid itself to naturally pass through the filter assembly to separate impurities. This filtration method has significant drawbacks. Due to the limited power of gravity filtration, the grinding fluid passes through the filter assembly slowly, resulting in a long filtration time and low filtration efficiency. This makes it difficult to meet the demands of large-scale machining production for rapid filtration and efficient recycling of grinding fluid. Furthermore, as filtration continues, a large amount of impurities gradually accumulates on the surface of the filter assembly, forming a filter cake layer. This further hinders the passage of grinding fluid, significantly reducing filtration efficiency and potentially causing blockage of the filter device, affecting normal production. Utility Model Content

[0005] The purpose of this invention is to provide a filter assembly and a grinding fluid circulation supply device. It adopts the centrifugal filtration principle and uses a servo motor to drive the filter cylinder to rotate. Under the combined action of centrifugal force and the filter membrane on the inner wall of the filter cylinder, the filtration efficiency is greatly improved to meet the needs of large-scale production. The top end cover of the filter housing can be easily removed by loosening the fixing bolts, and the fixing pin can be pulled to disengage it from the slot on the side of the filter cylinder. The filter membrane can be easily removed for cleaning and replacement, ensuring stable operation of the equipment.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A filtering component, comprising:

[0008] A filter housing for circulating and filtering grinding fluid, wherein a filter mechanism for centrifugal filtration of grinding fluid is installed inside the filter housing, and a removable end cap is installed on the top of the filter housing corresponding to the position of the filter mechanism.

This design makes the cleaning or replacement of the filter membrane simple and quick, eliminating the need for operators to spend a lot of time and effort on complex disassembly work. This effectively improves the efficiency of equipment maintenance, reduces the occurrence of situations where the filtration effect is affected by untimely or incomplete filter membrane replacement, and ensures the long-term stable operation of the grinding fluid filtration device.

[0020] 4. Ensures stable performance of the grinding fluid: Because this invention can quickly and efficiently remove metal residues, abrasive particles, and other impurities from the grinding fluid, it effectively avoids the accumulation of impurities in the grinding fluid, thus ensuring the stable performance of the grinding fluid.

[0035] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0036] Please refer to Figures 1 to 5 As shown, an embodiment of the present invention provides a filtration assembly, including: a filter housing 1 for circulating and filtering grinding fluid, a filter mechanism 2 for centrifugal filtering of grinding fluid installed inside the filter housing 1, and a detachable end cap 3 installed on the top of the filter housing 1 and at the position corresponding to the filter mechanism 2.

[0037] By adopting the above technical solution and using the centrifugal filtration principle, the servo motor 2011 drives the filter cylinder 2012 to rotate. Under the combined action of centrifugal force and the filter membrane 2013 on the inner wall of the filter cylinder 2012, the filtration efficiency is greatly improved to meet the needs of large-scale production. The top end cover 3 of the filter housing 1 can be easily removed by loosening the fixing bolt 301, and the fixing pin 20132 can be pulled to disengage it from the slot 20133 on the side of the filter cylinder 2012. The filter membrane 2013 can be easily removed for cleaning and replacement, ensuring stable operation of the equipment.

[0038] To achieve efficient centrifugal filtration, in this embodiment, the filtration mechanism 2 includes a mounting bracket 201 fixedly connected to the inner wall of the filter housing 1. A servo motor 2011 is fixedly connected to the top of the mounting bracket 201. A filter cylinder 2012 is mounted on the output shaft of the servo motor 2011. A removable filter membrane 2013 is provided on the inner wall of the filter cylinder 2012. The servo motor 2011 is securely installed inside the filter housing 1 by the mounting bracket 201. The servo motor 2011 drives the filter cylinder 2012 to rotate, causing the grinding fluid to quickly pass through the filter membrane 2013 under centrifugal force. Compared with traditional gravity filtration, this greatly improves the filtration efficiency and better meets the needs of rapid filtration of grinding fluid in large-scale machining. The removable filter membrane 2013 is designed for easy cleaning and replacement, ensuring the continuity of the filtration effect.

[0039] To ensure the stable rotation of the filter cartridge 2012, in this embodiment: a limiting slide rod 20121 is fixedly connected to the edge of the filter cartridge 2012, and an annular groove 20122 is provided on the inner wall of the filter housing 1 to cooperate with the limiting slide rod 20121. The cooperation between the limiting slide rod 20121 and the annular groove 20122 provides stable guidance and support for the rotation of the filter cartridge 2012, preventing the filter cartridge 2012 from deviating or shaking during high-speed rotation, ensuring that the centrifugal filtration process is stable and reliable, and improving the stability and service life of the equipment.

[0040] To facilitate the installation and removal of the filter membrane 2013, in this embodiment: a fixing hook 20131 matching the opening of the filter cylinder 2012 is fixedly connected to the top of the filter membrane 2013. The filter cylinder 2012 is hung on the filter cylinder 2012 via the fixing hook 20131. A fixing pin 20132 is provided on the side of the fixing hook 20131. A slot 20133 matching the fixing pin 20132 is provided on the side of the filter cylinder 2012 at the position corresponding to the fixing pin 20132. The filter membrane 2013 can be quickly hung on the filter cylinder 2012 using the fixing hook 20131. Then, the filter membrane 2013 is securely fixed by the cooperation of the fixing pin 20132 and the slot 20133. When the filter membrane 2013 needs to be removed for cleaning or replacement, simply pull the retaining pin 20132 to disengage it from the slot 20133, and the filter membrane 2013 can be easily removed. The operation is simple and convenient, greatly saving maintenance time.

[0041] To enable the retaining pin 20132 to automatically reset, in this embodiment, a spring 20134 is fitted onto the retaining pin 20132.

[0043] To ensure smooth flow of the grinding slurry, in this embodiment: an inlet pipe 302 is installed on the top of the end cap 3, and an outlet pipe 3021 is installed on the bottom of the filter housing 1. The inlet pipe 302 is located on the top of the end cap 3 to facilitate the introduction of the circulating grinding slurry into the filter cylinder 2012 inside the filter housing 1; the outlet pipe 3021 is installed at the bottom of the filter housing 1 to allow the filtered grinding slurry to flow out smoothly, thus achieving a circulating supply of the grinding slurry. This reasonable layout design ensures the smooth flow of the grinding slurry within the device and improves the overall efficiency of the filtration system.

[0044] A grinding fluid circulation supply device, comprising the filtration component of any one of the above.

[0045] The working principle of this utility model is as follows:

[0046] In use, the circulating grinding slurry is introduced into the filter cartridge 2012 inside the filter housing 1 through the inlet pipe 302 at the top of the end cap 3. Then, the servo motor 2011 on the mounting bracket 201 is started, driving the filter cartridge 2012 on the output shaft to rotate at high speed. Under centrifugal force, impurities in the grinding slurry are quickly thrown towards the inner wall of the filter cartridge 2012, and separated from the grinding slurry by the filtration action of the filter membrane 2013 on the inner wall of the filter cartridge 2012. The filtered pure grinding slurry then flows out from the outlet pipe 3021 at the bottom of the filter housing 1, completing a highly efficient centrifugal filtration process.

[0047] When cleaning or replacing the filter membrane 2013, first loosen the fixing bolts 301 at the edge of the end cap 3 to easily remove the end cap 3 from the top of the filter housing 1. Then, pull the fixing pin 20132 on the side of the fixing hook 20131 on the top of the filter membrane 2013 to disengage the fixing pin 20132 from the slot 20133 on the side of the filter cartridge 2012. At this point, the filter membrane 2013 can be easily removed from the filter cartridge 2012 for cleaning or replacement. After cleaning or replacement, reinstall the filter membrane 2013 by reversing the steps, and then fix the end cap 3 back to the top of the filter housing 1 for continued use. This design makes the maintenance and operation of the equipment simple and convenient, effectively ensuring the long-term stable operation of the grinding fluid filtration device.
