Description

Technical Field

[0001] This utility model relates to the field of CNC grinding machine cooling water recycling technology, specifically a CNC grinding machine cooling water iron chip filtration device. Background Technology

[0002] During the operation of a CNC grinding machine, the workpiece is ground by the grinding wheel, and the resulting iron filings mix with the cooling water. Since a large amount of cooling water is required during the grinding process, and in order to improve the utilization rate of water resources, the cooling water is often reused after filtration. In this process, a filtration device is used. Existing filtration devices often filter iron filings through a filter screen / cloth. However, because iron filings continuously accumulate on the filter screen / cloth, it is easy to get clogged, affecting the efficiency of cooling water flow and making it difficult to meet the usage requirements. Utility Model Content

[0009] The beneficial effects of this utility model are:

[0010] This type of filtration device can continuously magnetically remove magnetically attracted impurities such as iron filings from the cooling water. At the same time, it continuously cleans away the magnetically attracted impurities through the guide plate, preventing the surface of the adsorption roller from adsorbing a large amount of impurities.

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0016] like Figure 1-3 As shown, a cooling water chip filtration device for a CNC grinding machine includes an inlet chamber 1 and a filter chamber 2 that are interconnected. The inlet chamber 1 is provided with an inlet port 3, and the filter chamber 2 is provided with an outlet port 4. A partition 5 is provided between the inlet chamber 1 and the filter chamber 2. An arc-shaped guide plate 6 is provided on one side of the partition 5. The guide plate 6 is located inside the filter chamber 2. A rotating shaft 7 is provided inside the filter chamber 2. A magnetic cylindrical adsorption roller 8 is provided on the outer surface of the rotating shaft 7. A through groove is opened on the filter chamber 2. A guide plate 9 is provided on the filter chamber 2 and located on one side of the through groove. The upper end of the guide plate 9 abuts against the outer surface of the adsorption roller 8. A mounting frame 10 is provided on the outer surface of the filter chamber 2. A motor 11 is provided on the mounting frame 10. A sprocket 12 is provided at the output end of the motor 11 and one end of the rotating shaft 7, respectively. The two sprockets 12 are driven by a chain.

[0017] This filter device is used in the grinding of metal workpieces that can be attracted by magnets.

[0018] When filtering the cooling water used in the grinding process, the cooling water is first pumped into the inlet chamber 1 through the inlet port 3 by a water pump. When the cooling water in the inlet chamber 1 reaches a certain depth, the filtered water will enter the filter chamber 2 through the baffle 5 and the guide plate 6. At the same time, the motor 11 is started. Through the transmission of the motor 11, sprocket 12 and chain, the rotating shaft 7 and the adsorption roller 8 on the rotating shaft 7 can be rotated. The adsorption roller 8 has magnetic properties, such as... Figure 3 As shown, the adsorption roller 8 rotates clockwise. During the rotation, the adsorption roller 8 can magnetically attract iron filings in the coolant passing through the guide plate 6 to the surface of the adsorption roller 8, thereby effectively adsorbing iron filings and other substances that can be magnetically attracted by the adsorption roller 8 from the coolant. The magnetically attracted coolant is discharged from the outlet port 4 of the filter chamber 2.

[0019] During the adsorption process of iron filings and other impurities, the adsorption roller 8 will accumulate on its surface. In order to improve the filtration efficiency and effect of magnetically attracted impurities such as iron filings in the cooling water, the guide plate 9 can continuously contact the surface of the adsorption roller 8 during its rotation. This causes the magnetically attracted impurities on the surface of the adsorption roller 8 to accumulate at the junction between the adsorption roller 8 and the guide plate 9. As the impurities accumulate, they will gradually separate from the adsorption roller 8 and slide down along the guide plate 9. Thus, when the surface of the adsorption roller 8 passes the guide plate 6, the adsorption roller 8 can effectively magnetically attract impurities in the cooling water.

[0020] The cooling water level in the inlet chamber 1 will not completely submerge the adsorption roller 8. Usually, the water level in the inlet chamber 1 is located at 2 / 3 of the total height of the inlet chamber 1. Meanwhile, the particle size of the impurities is usually around 10 micrometers. When the cooling water enters the inlet chamber 1 from the inlet port 3, the impact of the water flow will cause the impurities in the inlet chamber 1 to float. That is, when water flows into the inlet chamber 1, the impurities in the inlet chamber 1 will not sink to the bottom or remain still for a long time. Instead, they will float up with the impact of the water flow and enter the filter chamber 2 through the guide plate 6.

[0021] Furthermore, the filter chamber 2 is provided with support frames 13 on both sides, and also includes a rubber roller 14. The two ends of the rubber roller 14 are respectively provided with fixing blocks 15. The rubber roller 14 is rotatably connected to the fixing blocks 15. It also includes a bolt 16 rotatably connected to the fixing blocks 15. The lower end of the bolt 16 is threadedly connected to the support frame 13. A spring 17 is sleeved on the bolt 16. The spring 17 is located above the fixing block 15. The outer surface of the rubber roller 14 is always in contact with the outer surface of the adsorption roller 8. The pressure of the spring 17 on the fixing block 15 can be controlled by rotating the bolt 16, thereby controlling the pressure between the rubber roller 14 and the adsorption roller 8. This ensures that during the rotation of the adsorption roller 8, the rubber roller 14 is passively rotated by the friction between it and the adsorption roller 8. At the same time, the rotation direction of the rubber roller 14 and the adsorption roller 8 is opposite.

[0022] When the adsorption roller 8 rotates, the water adhering to the surface of the adsorption roller 8 is easily cleaned away by the guide plate 9, resulting in the loss of cooling water. However, the rubber roller 14 can squeeze out the cooling water adhering to the surface of the adsorption roller 8. After the cooling water on the surface of the adsorption roller 8 is squeezed out by the rubber roller 14, there is no excess cooling water on the adsorption roller 8 that is cleaned away by the guide plate 9, thereby reducing the loss of cooling water.

[0023] Furthermore, a cover 18 is provided on the outer surface of the filter chamber 2, and the sprocket 12 and the chain are both located inside the cover 18.

[0024] Furthermore, the horizontal height at both ends of the guide plate 6 is higher than the horizontal height in the middle of the guide plate 6, ensuring that the adsorption roller 8 can effectively filter the cooling water flowing through the guide plate 6.

[0025] Furthermore, both ends of the guide plate 6 are fixed inside the filter chamber 2 to improve the stability of the guide plate 6 inside the filter chamber 2. The guide plate 6 can be made of metal, rubber, or plastic.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
