Description

Technical Field

[0001] This utility model relates to the field of coolant filtration, and in particular to a coolant filtration device for CNC machine tools. Background Technology

[0002] Coolant is a special functional liquid used in CNC machine tool machining to cool, lubricate, clean, and prevent rust in the machining area. Coolant filtration is the process of separating solid impurities from the coolant, restoring it to a clean state so that it can be recycled and reused. Its core objectives are to maintain coolant performance, ensure machining quality, extend the life of equipment and tools, and reduce resource consumption.

[0003] However, current methods of filtering coolant only employ a single filtration structure, which can only intercept larger solid impurities in the coolant. The filtration effect on smaller impurities is limited, which can easily lead to impurities remaining in the coolant. Furthermore, it is difficult to filter and collect tiny magnetic metal impurities during use, which will increase the amount of waste coolant discharged, increase consumable costs, and increase environmental treatment pressure. To address these issues, we propose a CNC machine tool coolant filtration device. Utility Model Content

[0004] The purpose of this invention is to provide a CNC machine tool coolant filtration device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A CNC machine tool coolant filtration device includes a support base, a filter shell fixedly mounted on the upper surface of the support base, a collection box fixedly mounted on the upper surface of the support base, a first filter plate fixedly mounted on the inner wall of the filter shell, a second filter plate fixedly mounted on the inner wall of the filter shell, a screw pump fixedly mounted on the upper surface of the support base, a suction pipe fixedly connected to the input end of the screw pump, the end of the suction pipe away from the screw pump passing through the filter shell and extending into the interior of the filter shell, a delivery pipe fixedly connected to the output end of the screw pump, a conveying pipe fixedly connected to the end of the delivery pipe away from the screw pump, two outlet pipes fixedly connected to the outer surface of the conveying pipe, the ends of the two outlet pipes away from the conveying pipe passing through the collection box and extending into the interior of the collection box, and two electromagnets fixedly mounted on the inner wall of the collection box.

The front of the first filter plate and the front of the second filter plate are in contact with the back of the first inspection plate.

[0007] In a further embodiment, a second inspection port is provided on the back of the collection box, and a second inspection plate is fixedly installed on the back of the collection box, with the backs of both electromagnets in contact with the front of the second inspection plate.

[0008] In a further embodiment, the upper surface of the support base has two sets of mounting ports, and a PLC controller is fixedly mounted on the front of the filter shell.

[0009] In a further embodiment, a connecting plate is fixedly installed on the upper surface of the filter shell, and an inlet hopper is fixedly connected to the upper surface of the connecting plate.

Extending into the interior of the collection tank 3, two electromagnets 11 are fixedly installed on the inner wall of the collection tank 3. The two electromagnets 11 are waterproof. With the setting of the first filter plate 4 and the second filter plate 5, larger solid impurities in the coolant can be initially intercepted and filtered, and smaller impurities in the coolant can be further filtered, thus performing secondary filtration of the coolant and effectively avoiding impurity residue. With the setting of the screw pump 6, the liquid extraction pipe 7, the liquid delivery pipe 8, the delivery pipe 9 and the two liquid outlet pipes 10, together with the two electromagnets 11, can draw and deliver the coolant that has been filtered twice, and adsorb the residual magnetic metal impurities in the coolant, further removing impurities in the coolant, reducing the discharge of waste coolant, improving the filtration effect of the coolant, reducing consumable costs and environmental treatment pressure.

[0021] The filter housing 2 has a first inspection port 12 on its front side, and a first inspection plate 13 is fixedly installed on the front side of the filter housing 2. The front sides of the first filter plate 4 and the second filter plate 5 are in contact with the back side of the first inspection plate 13. The collection box 3 has a second inspection port 14 on its back side, and a second inspection plate 15 is fixedly installed on its back side. The back sides of the two electromagnets 11 are in contact with the front side of the second inspection plate 15.

The second inspection port 14 and the second inspection plate 15 facilitate the maintenance or cleaning of the two electromagnets 11, reducing the difficulty of maintenance and cleaning of the two electromagnets 11.

[0022] The upper surface of the support base 1 has two sets of mounting ports 16. A PLC controller 17 is fixedly mounted on the front of the filter housing 2.

Furthermore, the electrical components in this application are all common electrical equipment in the prior art. This application will not elaborate on their models or internal structures.

[0023] The working principle of this utility model is as follows: First, the coolant to be filtered is injected into the filter housing 2 through the inlet hopper 19. Simultaneously, the injected coolant flows through the first filter plate 4, which initially intercepts and filters larger solid impurities in the coolant. The coolant continues to flow downwards through the second filter plate 5, where it further filters smaller impurities, performing a second filtration. Then, the screw pump 6 is started to extract the coolant that has undergone two filtrations from the filter housing 2 through the extraction pipe 7. Subsequently, the coolant is transported through the delivery pipe 8 to the delivery pipe 9, and then through two outlet pipes 10 to the collection tank 3. Finally, two electromagnets 11 are activated to adsorb any remaining magnetic metal impurities in the coolant transported to the collection tank 3, further removing impurities from the coolant.
