Description

Technical Field

[0001] This invention relates to the field of grinding mill technology, and in particular to an intelligent filtration method and filtration equipment for grinding mill fluid. Background Technology

[0002] Grinding is an important processing method in ultra-precision machining. Its advantages are high processing accuracy and a wide range of processing materials. Magnetic grinding machines improve upon the shortcomings and defects of traditional grinding machines, enabling precision metal workpieces to achieve significantly better polishing, grinding, and burr removal effects.

[0003] However, after using existing magnetic polishing machines, grinding impurities remain in the polishing tank. This necessitates manual replacement of the polishing fluid, which involves draining water, recovering the polishing needles, remixing the polishing fluid, and adding water. Therefore, frequent replacements result in a short lifespan for the polishing fluid, requiring timely replacement. Furthermore, replacing the polishing fluid is a complex, labor-intensive, and inefficient process. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this invention is to provide an intelligent filtration method and filtration device for grinding fluid in a grinding mill, so as to solve the above-mentioned technical problems.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A method for intelligent filtration of grinding fluid in a grinding mill includes grinding grade parameters and filtration pressure parameters; setting purity parameters based on the grinding grade parameters; and further includes the following steps:

[0007] S1: Detects actual purity and filter pressure;

[0008] S2: If the actual purity is less than the purity parameter, the filtration equipment will start the filtration mode; if the actual purity is greater than or equal to the purity parameter, the filtration equipment will be turned off and the grinder will operate normally.

[0009] S3: In S2, if the filter pressure is greater than the filter pressure parameter, then step S2 will stop, the equipment will activate the alarm mode to notify manual replacement of the filter element, and after replacement, step S2 will continue.

[0010] As a further improvement of the present invention: a preset purity threshold value is set, and during normal operation of the grinder in S2, the following steps are also included:

[0011] S21: If the actual purity is less than the purity threshold, the grinder will stop running and the equipment will start the alarm mode. After the grinder completes this grinding, the filtration equipment will immediately start the filtration mode.

[0012] As a further improvement of the present invention: the filtration mode includes energizing the worktable to magnetize the grinding tank, attracting the abrasive material in the grinding liquid by magnetic force, and then turning on the water pump to extract the remaining liquid. The extracted liquid enters the filter and is then returned to the grinding tank to be mixed with the abrasive material again.

[0013] As a further improvement of the present invention: the alarm modes include alarm device alarm and alarm light alarm.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0028] Example 1:

[0029] This embodiment provides the following: Figure 1-2 The method for intelligent filtration of grinding fluid in a grinding mill, as shown, includes grinding grade parameters and filtration pressure parameters; setting purity parameters based on the grinding grade parameters; and further includes the following steps:

[0030] S1: Detects actual purity and filter pressure;

[0031] S2: If the actual purity is less than the purity parameter, the filtration equipment will start the filtration mode; if the actual purity is greater than or equal to the purity parameter, the filtration equipment will be turned off and the grinder will operate normally.

[0032] S3: In S2, if the filter pressure is greater than the filter pressure parameter, then step S2 will stop, the equipment will activate the alarm mode to notify manual replacement of the filter element, and after replacement, step S2 will continue.

[0033] In this embodiment, the initial setup involves setting two parameters: a purity parameter and a filtration pressure parameter. The purity parameter is set to monitor the filter element's condition during filtration and prevent it from affecting the filtration efficiency. Since different grinding parts have varying cleanliness requirements, to ensure the grinding parts achieve the desired purity, a grinding grade parameter is first set. This parameter clarifies the standard range of purity levels, and the specific purity parameter is determined within the selected grade range. The purpose of setting the purity parameter is to ensure the actual grinding fluid's purity meets the required standard.

[0034] This invention simultaneously detects the actual purity and filter pressure; because impurities will mix into the grinding slurry during multiple grinding processes, the purity of the grinding slurry will decrease.

[0035] When the purity of the grinding fluid is lower than the set requirement: If the actual purity is less than the purity parameter, the purity of the grinding fluid is considered to be insufficient, and the filtration function is activated: The worktable is powered on and magnetized to attract the metal grinding material in the grinding tank (the grinding material is generally stainless iron or other metal materials that can be fixed by magnetic attraction), which solves the problem of the grinding material being drawn out by the water pump and clogging the water outlet. After the grinding material is fixed, the water pump is turned on to extract the grinding fluid → the grinding fluid is pumped into the filter → the grinding fluid is filtered → the filter pumps out clean grinding fluid → it is circulated back to the grinding tank, completing one filtration cycle. After filtration is completed, normal grinding can be started.

[0036] When the detected filter pressure is higher than the set requirement: If the detected filter pressure is greater than the filter pressure parameter, it is considered that the filter element's filtration function does not meet the usage requirements. The suspended solids detection will be automatically turned off and an alarm will be triggered. After replacing the filter element, normal operation will resume.

[0037] Therefore, dual testing is used to ensure the purity of the grinding slurry meets the required standards, filtering out impurities so that they do not affect subsequent grinding operations.

[0038] Example 2:

[0039] This embodiment provides the following: Figure 1-3 The method for intelligent filtration of grinding fluid in a grinding mill, as shown, includes grinding grade parameters and filtration pressure parameters; setting purity parameters based on the grinding grade parameters; and further includes the following steps:

[0040] S1: Detects actual purity and filter pressure;

[0041] S2: If the actual purity is less than the purity parameter, the filtration equipment will start the filtration mode; if the actual purity is greater than or equal to the purity parameter, the filtration equipment will be turned off and the grinder will operate normally.

[0042] S3: In S2, if the filter pressure is greater than the filter pressure parameter, then step S2 will stop, the equipment will activate the alarm mode to notify manual replacement of the filter element, and after replacement, step S2 will continue.

[0043] In this embodiment, the purity of the grinding slurry after one filtration initially meets the requirements. However, its purity will continuously decrease during repeated use. If the change in the purity of the grinding slurry exceeds a certain range during use, it will affect the quality of the product. However, since the grinding process is in progress, turning on the filtration function during grinding would also affect the quality of the product. Therefore, in this embodiment, an additional detection step is added as follows:

[0044] The preset purity threshold, when the grinder in S2 is running normally, also includes the following steps:

[0045] S21: If the actual purity is less than the purity threshold, the grinder will stop running and the equipment will start the alarm mode. After the grinder completes this grinding, the filtration equipment will immediately start the filtration mode.

[0046] Specifically, when the purity of the grinding slurry detected during grinding reaches a set critical value: If the actual purity is less than the critical value, meaning the purity is about to reach the set critical value, the equipment will activate an alarm mode. After completing the current grinding cycle, the equipment will automatically filter the grinding slurry immediately. This is to prevent the equipment from activating the filtration function during the grinding process, which could affect product quality. This function can be enabled as needed. If the product surface finish requirements are low, this function can be disabled, and automatic filtration will only occur when the purity exceeds the limit (this function is generally enabled to avoid poor product appearance consistency).

[0047] Specifically, in this embodiment, in order to ensure that the polishing slurry is always in a state close to the purity parameter value, the purity threshold is set to 95% of the purity parameter value, thereby meeting the purity requirements of the polishing slurry and matching the polishing parts that are more delicate and have higher requirements for the cleanliness of the parts.

[0048] In the above-mentioned filtration mode, the filtration mode includes energizing the worktable to magnetize the grinding tank, attracting the abrasive material in the grinding liquid through magnetic force, and then turning on the water pump to extract the remaining liquid. The extracted liquid enters the filter for filtration and then returns to the grinding tank to be mixed with the abrasive material again.

[0049] Preferably, the alarm modes include alarm device alarm and alarm light alarm.

[0050] The grinding grade parameters in this invention will be described in further detail, and the grinding grade parameters include a range of multi-level standard parameters.

[0051] In one embodiment, the grinding grade parameters include a three-level standard parameter range, which includes a first-level standard parameter range, a second-level standard parameter range, and a third-level standard parameter range.

[0052] Specifically, the primary standard parameter range is 70-100 mg / L; the secondary standard parameter range is 200-250 mg / L; and the tertiary standard parameter range is 300-400 mg / L.

[0053] Example 3:

[0054] This embodiment also provides the following: Figure 2-3 The diagram illustrates an intelligent filtration device for grinding fluid in a grinding mill, employing the intelligent filtration method described above. The grinding mill includes a grinding tank 1; the filtration device includes a detection sensor 2, a processor, a water pump, a filter, and an outlet pump. The detection sensor is disposed within the grinding tank, connected to the processor, the processor to the water pump, the water pump to the filter, the filter to the outlet pump, and the outlet pump to the grinding tank. The detection sensor includes a suspended solids detection sensor and a pressure sensor. Multiple suspended solids detection sensors are arranged in a matrix on the grinding tank.

[0055] In this embodiment, the grinding tank 1 (including a suspended solids detection sensor and a processor), the water pump, the filter, and the outlet pump are respectively installed as shown in the attached diagram. Figure 2 Simply connect them in series. This is achieved by arranging the materials in a matrix within the grinding tank (to ensure detection accuracy and solution uniformity, a matrix arrangement with equal spacing in both length and width directions is used, as shown in the attached diagram). Figure 3 A suspended solids detection sensor monitors the grinding fluid in the tank in real time. If the level exceeds a set range, the filtration method is activated to filter the grinding fluid, thereby achieving a clean environment that does not require manual replacement. Additionally, a pressure sensor is installed at the filtration point. When the filter cartridge pressure is too high, the suspended solids detection function is deactivated, and an alarm is triggered to prompt for filter cartridge replacement.

[0056] This embodiment includes two setup steps before use, which are set according to requirements: grinding grade parameters, purity parameters, and filtration pressure parameters. After the required parameters are set, the user activates the grinding fluid purity sensing function, at which point the suspended solids detection sensor starts working and monitors the purity of the grinding fluid in real time. Simultaneously, the user can change the purity parameters via the control panel according to different grinding appearance requirements for the parts. Upon restarting the equipment, monitoring will proceed according to the current settings.

[0057] 1. In this embodiment, the grinding level parameter can be set to any value, and can be divided into three standards: Level 1 standard: 70-100mg / L, Level 2 standard: 200-250mg / L, and Level 3 standard: 300-400mg / L. The value depends on the amount of grinding fluid and the user's requirements for the cleanliness of the grinding parts. Generally, Level 2 standard is sufficient. The higher the requirement, the smaller the value should be. Whether to enable this monitoring function can also be determined according to customer needs.

[0058] 2. This intelligent filtration method can be applied to any liquid that needs to be filtered;

[0059] 3. In this embodiment, the filter element can be selected according to customer needs. Generally, PP cotton type filter element is sufficient, while activated carbon filter element can be selected for higher requirements.

[0061] 5. In this embodiment, the pressure sensor can be replaced with a pressure gauge according to customer needs, and can be monitored manually.
