Abstract
Description
Technical Field
[0001] This utility model relates to the field of working fluid filtration and treatment technology, specifically to an advanced ceramic grinding working fluid filtration and supply system. Background Technology
[0002] The pump supplies the working fluid to the terminal filter and then to the processing area. The working fluid in the processing area flows back to the working fluid tank. Through sedimentation and filtration through layers of filters in the working fluid tank, most of the impurities are filtered to the bottom of the working fluid tank (which needs to be manually cleaned periodically). However, there are still tiny particles of impurities in the working fluid that cannot be filtered out. The longer the processing time, the more difficult the filtration will become if manual cleaning and working fluid replacement are not timely, and the more viscous the working fluid will become. Utility Model Content
[0003] The purpose of this invention is to provide an advanced ceramic grinding working fluid filtration and supply system to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an advanced ceramic grinding working fluid filtration and supply system, including a housing, and further comprising: A partition is fixedly connected inside the housing. A supply area is provided on the front side of the housing, and a return area is provided on the right side of the housing. A filter mechanism is provided inside the housing, and an assembly mechanism is provided on the surface of the filter mechanism. The filtration mechanism includes: A terminal filter is fixedly connected inside the housing, and a working fluid output end is fixedly connected to the surface of the filter, with the opening of the working fluid output end designed to face upwards.
[0005] Preferably, a supply pump and a storage filter are fixedly connected inside the housing. Both the supply pump and the storage filter are located in the supply area. The inlet end of the supply pump is connected to the outlet end of the storage filter in the supply area, and the outlet end of the supply pump is connected to the inlet end of the terminal filter. The storage filter, as a "primary filtration unit", first performs preliminary filtration on the working fluid in the supply area (removing larger particulate impurities, such as coarse powder generated from ceramic grinding), preventing large impurities from directly entering the terminal filter, preventing the terminal filter from clogging, extending its service life, and reducing the load on the terminal filter.
[0006] Preferably, a filter pump is installed in the reflux zone. The outlet of the filter pump is connected to the inlet of the supply zone, and the inlet of the filter pump is connected to the outlet of the reflux zone. The function of the reflux zone is to receive the "contaminated working fluid" (containing ceramic grinding powder, tool wear debris, etc.) flowing back from the processing area. Since gravity-driven reflux is slow, the filter pump actively extracts and forces the contaminated working fluid from the reflux zone to the supply zone, accelerating the circulation of the working fluid in the "reflux zone → supply zone → processing zone," preventing the accumulation of working fluid in the reflux zone and ensuring smooth overall system circulation.
[0007] Preferably, a drawer-type liquid tank is provided in the reflux zone, and a filter screen is provided inside the drawer-type liquid tank. The inlet end of the drawer-type liquid tank is connected to the working liquid tank in the processing area, and the outlet end of the drawer-type liquid tank is connected to the inlet end of the supply area. The filter screen acts as the "first impurity interception barrier" in the reflux zone, directly filtering the working liquid flowing back from the processing area (intercepting most of the grinding debris and powder). Large particulate impurities are left in the drawer-type liquid tank to prevent them from entering the subsequent filter pump or supply area. This is a "pre-treatment" of the reflux liquid, further improving the filtration efficiency of the entire system.
[0008] Preferably, the assembly mechanism includes a filter element disposed within the terminal filter. A cap body is disposed on the top of the filter element, and a cap screw is threadedly connected to the center of the cap body. A flat gasket is disposed between the terminal filter and the cap body, and an O-ring rubber seal is disposed between the flat gasket and the cap body. The filter element is the "core filtration component" of the terminal filter, and its filtration accuracy is much higher than that of storage filters and drawer-type filters (such as those capable of filtering micron-sized ceramic powder). It can filter the working fluid supplied by the pump to "machining-grade cleanliness," ensuring that the working fluid finally supplied to the grinding area is free of minute impurities, thus avoiding defects on the surface of ceramic workpieces (which are hard but brittle and easily scratched by impurities).
[0009] Preferably, a liquid level alarm bracket is provided in the supply area, and a float assembly is provided on the surface of the liquid level alarm bracket. The float assembly (the float floats up and down with the liquid level) is installed on the liquid level alarm bracket. The bracket fixes the position of the float and ensures that it can accurately sense the working liquid level in the supply area. The float and the alarm (integrated into the system, with the bracket providing the mounting base) are linked and can provide real-time feedback of liquid level data.
[0010] Preferably, the reflux zone is used to receive the returned working fluid. The inlet end of the reflux zone is connected to the working fluid tank. The "working fluid tank" in the processing area is the main area where the working fluid and grinding impurities mix. Directly connecting the reflux zone to the working fluid tank ensures that the "contaminated working fluid" containing impurities after processing can flow 100% back to the reflux zone, avoiding leakage of contaminated fluid, causing a dirty workshop environment, or wasting working fluid.
[0011] Compared with the prior art, this utility model provides an advanced ceramic grinding working fluid filtration and supply system, which has the following beneficial effects: This advanced ceramic grinding working fluid filtration and supply system uses a designated supply zone to buffer the working fluid, separating the supply and filtration of the working fluid to the processing area. Specifically, the supply pump and the return filter assembly operate independently, ensuring both effective double-layer filtration of the working fluid and maintaining the flow rate and pressure of the working fluid supplied to the processing area. Even if the return filter assembly becomes clogged, reducing the flow rate of the filtered working fluid delivered to the supply zone, it does not affect the pressure and flow rate supplied by the supply pump. This effectively solves the problem of difficult filtration of working fluids containing numerous tiny particles generated during the processing of special materials, ensuring the flow rate and pressure of the working fluid and improving processing efficiency and safety.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] This utility model provides a technical solution: Example 1:
[0016] Combination Figure 1-8 An advanced ceramic grinding working fluid filtration and supply system, including a housing 1, also includes: The partition 5 is fixedly connected inside the housing 1. The front side of the housing 1 is provided with a supply area 6, and the right side of the housing 1 is provided with a return area 4. A filter mechanism 2 is provided inside the housing 1, and an assembly mechanism 3 is provided on the surface of the filter mechanism 2; Filter mechanism 2 includes: Terminal filter 21 is fixedly connected inside housing 1. Working fluid output end 27 is fixedly connected to the surface of the filter. The working fluid output end 27 is designed with its opening facing upward.
[0017] Furthermore, a supply pump 22 and a storage filter 23 are fixedly connected inside the housing 1. Both the supply pump 22 and the storage filter 23 are located in the supply area 6. The inlet end of the supply pump 22 is connected to the outlet end of the storage filter 23 in the supply area 6, and the outlet end of the supply pump 22 is connected to the inlet end of the terminal filter 21. The storage filter 23, as a "first-level filtration unit", first performs preliminary filtration on the working fluid in the supply area 6 (removing larger particulate impurities, such as coarse powder generated by ceramic grinding), preventing large impurities from directly entering the interior of the terminal filter 21, preventing the terminal filter 21 from clogging, extending its service life, and reducing the load on the terminal filter.
[0018] Furthermore, a filter pump 24 is installed in the reflux zone 4. The outlet of the filter pump 24 is connected to the inlet of the supply zone 6, and the inlet of the filter pump 24 is connected to the outlet of the reflux zone 4. The function of the reflux zone 4 is to receive the "contaminated working fluid" (containing ceramic grinding powder, tool wear debris, etc.) flowing back from the processing area. Since gravity reflux alone is slow, the filter pump 24 actively extracts and forces the contaminated working fluid from the reflux zone 4 to the supply zone 6, accelerating the circulation of the working fluid in the "reflux zone 4 → supply zone 6 → processing zone", preventing the working fluid from accumulating in the reflux zone 4 and ensuring smooth overall system circulation.
[0019] Furthermore, a drawer-type liquid tank 26 is installed in the return zone 4, and a filter screen 25 is installed inside the drawer-type liquid tank 26. The liquid inlet of the drawer-type liquid tank 26 is connected to the working liquid tank in the processing area, and the liquid outlet of the drawer-type liquid tank 26 is connected to the liquid inlet of the supply zone 6. The filter screen 25 acts as the "first impurity interception barrier" of the return zone 4, directly filtering the working liquid flowing back from the processing area (intercepting most of the grinding debris and powder). Large particulate impurities are left in the drawer-type liquid tank 26 to prevent them from entering the subsequent filter pump 24 or the supply zone 6. This is a "pre-treatment" of the return liquid, which further improves the filtration efficiency of the entire system.
[0020] Example 2:
[0021] Based on Embodiment 1, the assembly mechanism 3 further includes a filter element 32, which is disposed within the terminal filter 21. A pressure cap body 37 is disposed on the top of the filter element 32, and a pressure cap screw 36 is threadedly connected in the middle of the pressure cap body 37. A flat gasket 31 is disposed between the terminal filter 21 and the pressure cap body 37, and an O-ring rubber sealing ring 33 is disposed between the flat gasket 31 and the pressure cap body 37. The filter element 32 is the "core filtration component" of the terminal filter 21, and its filtration accuracy is much higher than that of the storage filter 23 and the drawer-type filter screen 25 (such as being able to filter micron-sized ceramic fine powder). It can filter the working fluid delivered by the supply pump 22 to "machining-grade cleanliness", ensuring that the working fluid finally supplied to the grinding area is free of tiny impurities, and avoiding defects on the surface of ceramic workpieces (which are hard but brittle and easily scratched by impurities).
[0022] Furthermore, a liquid level alarm bracket 34 is installed in the supply area 6. A float assembly 35 is installed on the surface of the liquid level alarm bracket 34. The float assembly 35 (the float floats up and down with the liquid level) is installed on the liquid level alarm bracket 34. The bracket fixes the position of the float and ensures that it can accurately sense the working liquid level of the supply area 6. The float and the alarm (built into the system, the bracket provides the mounting base) are linked and can provide real-time feedback of liquid level data.
[0023] Furthermore, the reflux zone 4 is used to receive the returned working fluid. The inlet end of the reflux zone 4 is connected to the working fluid tank. The "working fluid tank" in the processing area is the main area where the working fluid and grinding impurities mix. By directly connecting the reflux zone 4 to the working fluid tank, it is ensured that the "contaminated working fluid" containing impurities after processing can flow 100% back to the reflux zone 4, avoiding leakage of contaminated fluid, causing a dirty workshop environment, or wasting working fluid.
[0024] In actual operation, the working fluid used in the processing area (containing fine particulate impurities such as advanced ceramic chips) is first concentrated in the working fluid tank of the processing area, and then flows through the pipeline from the machine tool return port to the "return zone 4" of the system to complete the initial collection of the working fluid. The filter pump 24 configured in the return zone 4 starts. Since the pump head of the filter pump 24 is immersed in the working fluid in the return zone 4, the working fluid in the return zone 4 can be directly delivered to the storage filter 23 (filter element 32 type filter barrel, with a filter element 32 that matches the filter element 32 cavity inside. The axial length of the filter element 32 cavity is greater than that of the filter element 32 to ensure the filtration effect) in the "filtration zone". When the working fluid flows through the storage filter 23, the fine particulate impurities in it are intercepted by the filter element 32. The filtered clean working fluid is then guided to the "supply zone 6" for storage through the liquid outlet of the storage filter 23 to complete the initial filtration. Supply area 6 serves as a dedicated buffer area, receiving and storing the cleaning working fluid after the initial filtration. Its storage capacity must meet the working fluid usage for at least one processing cycle. The core function of this stage is to "isolate the filtration and supply process". Even if the subsequent return filtration process becomes clogged, resulting in a reduction in the influent volume, the cleaning working fluid already stored in supply area 6 can still guarantee the processing needs, avoiding the direct impact of filtration problems on supply stability. When the processing area requires working fluid, the supply pump 22 configured in the supply area 6 is started. The inlet of the supply pump 22 is connected to the outlet of the storage filter 23 in the supply area 6, which can draw the cleaning working fluid from the supply area 6 to the "terminal filter 21" (secondary filtration equipment). When the working fluid flows through the terminal filter 21, it is filtered again by the filter element 32 to further intercept any possible residual small particulate impurities, achieving "double-layer filtration" to ensure the cleanliness of the working fluid delivered to the processing area. The cleaning working fluid after secondary filtration is directly delivered to the processing area through the working fluid spray pipe in the processing area through the outlet of the terminal filter 21, meeting the requirements for working fluid flow and pressure during the processing and completing the supply. After use in the processing area, the working fluid will re-enter the working fluid tank and repeat the above "recirculation-filtration-buffering-supply" process to form a continuous cycle. If the recirculation filtration process is blocked (such as the accumulation of impurities in the storage filter 23 and filter element 32), the flow rate of the working fluid entering the supply area 6 will decrease. Since the supply area 6 has stored enough clean working fluid, the supply pump 22 can still stably draw working fluid from the supply area 6, without affecting the working fluid pressure and flow rate output by the terminal filter 21, thus ensuring processing efficiency and safety.
