The chain 16 is a sprocket The motor 19 is driven by a motor 19 (see Fig. 2). It is configured to circulate within the tank 11. The filter paper 30 is wound into a roll and is placed on the top of the tank 11, with the end of the filter paper 30 being wound into a roll. It is sandwiched between the chain 11 and the chain 16 and covers the discharge port 13. At the top of tank 11 is a clean tank that stores filtered clean coolant C. 31 are provided. There is a filter between the tank 11 and the clean tank 31. A pump 32 is provided for feeding coolant into a clean tank 31. Ta A pressure sensor is installed between the pump 32 and the pump 32 to detect the pressure inside the suction chamber 14. 33 are provided. The clean tank 31 is designed to prevent coolant from overflowing. An overflow pipe 34 and a supply pump 3 that sends coolant to a machine tool (not shown) 5 is provided.

[0007] A winding mechanism 40 for winding up the used filter paper 301 is provided outside the tank 11. It is. The winding mechanism 40 is a filter paper winding motor that rotates a filter paper core tube 41 that winds up the filter paper 301. 42 (see FIG. 3). One end of the filter paper core tube 41 is connected to the filter paper winding motor 42. It is supported by a drive roller 43 and a free roller 44, and the other end is supported by a pair of free rollers 4. It is supported by 5.45. Filter paper winding motor 42, free rollers 44, 45, 4 5 is provided on a pair of support plates 46, 46 provided outside the tank 11. A sludge removing means 50 is installed between the outlet of the tank 11 and the filter paper core tube 41. I'm being kicked. The sludge removing means 50 is tiltably supported by the support plates 46, 46. A scraper 52 is provided between a pair of tilting links 51 and 51. A support shaft 53 that supports the used filter paper 301 from the back side rotates near the scraper 52. It is equipped with a rotatable structure. A sludge receiving box 54 is installed below the filter paper core tube 41. ing.

[0008] Next, the operation will be explained. Dirty coolant D sent from the machine tool flows into the tank 11. The dirty coolant D is passed through the filter paper 30 and the suction chamber 14 by the pump 32. The coolant C becomes clean coolant C and is sent to the clean tank 31. dirt When the coolant is filtered through the filter paper 30, it becomes a clean coolant. The coolant that has flowed into the clean tank 31 is processed by the supply pump 35. sent to the machine. On the other hand, sludge such as cutting powder and grinding powder contained in the dirty coolant can be removed using filter paper 30. The coolant gradually accumulates in the coolant, clogging the filter paper 30, and impairing the flow of the coolant. child During this period, the pump 32 continues the suction operation, so the pressure inside the suction chamber 14 is reduced to a tamp. The pressure inside the tank 11 is gradually lowered. This state continues and the pressure in the suction chamber 14 increases. When the pressure becomes lower than a predetermined pressure, the pressure sensor 33 senses this and turns on the pump 32. make it stop. Therefore, the flow between the pump 32 and the suction chamber 14 is stopped, and the tank 11 When the clean coolant flowing into the suction chamber 14 gradually accumulates in the suction chamber 14, At this moment, the pressure inside the suction chamber 14 approaches a predetermined pressure.

[0009] Thereafter, the motor 19 with a speed reducer is started to move the chain 16 in circulation. filter The weight of the chain 16 is applied to the paper 30, and the chain 16 is connected to the chain 16. The filter paper 30 is pulled and moved using the drag force F1 caused by the friction generated between the filter paper 30 and the filter paper 30. let Of course, the drag force F1 is the frictional resistance force F between the filter paper 30 and the tank 11. It is set to be greater than 2. Thus, the clogged part of the filter paper The used filter is moved from the discharge port 13 to the rising wall 36 of the tank 31 and placed outside the tank 11. It is discharged as paper. When the clogged part of the filter paper moves to the rising wall 36, a new part of the filter paper is discharged. It is drawn onto the mouth 13. After that, the motor 19 stops and the pump 32 starts operating again. Start. During this time, the clean coolant C stored in the clean tank 31 is It continues to be sent to the machine tool by the feed pump 35 and is consumed. But again, When the pump 32 is operated, the liquid level is restored.

0010 On the other hand, the used filter paper 301 discharged outside the tank 11 is simultaneously The filter paper core tube 41 is rotated by the rotating filter paper winding motor 42 in the form of a roll. It is wound up. At this time, the sludge S attached to the used filter paper 301 is removed by the scraper 52. The sludge is removed and falls into the sludge receiving box 54. The scraper 52 uses its own weight and is in contact with the filter paper 301. The above operation is automatically repeated every time the filter paper 30 becomes clogged. Since the rotation speed of the filter paper winding motor 42 is always constant, the used filter paper 301 cannot be wound up. As the diameter of the filter paper increases, the amount of paper to be wound up is greater than the amount of filter paper ejected. There is a risk that the used filter paper 301 will be torn. However, the filter paper core tube 41 is 3 and free rollers 44, 45, 45, each The used filter paper 301 is damaged due to slip rotation on the rollers 43, 44, 45, and 45. prevent. Therefore, due to the slip rotation, the used filter paper 301 Almost constant tension is always applied to prevent the used filter paper 301 from loosening. Then, the filter paper 301 is wound up in a tight state.

[0011] The filter paper core tube 41 of the above winding mechanism 40 is rotated by the filter paper winding motor 42. However, as in the winding mechanism 140 shown in FIG. motor through the sprocket 155, chain 156, and sprockets 157, 158. It rotates by a drive roller 143 and a free roller 144 that are interlocked with the roller 19. You may do so. In addition, the polluted liquid filtration device 10 explained above has a suction chamber by the pump 32. The pressure inside the tank 14 is lowered than the pressure inside the tank 11, and the dirty coolant D is transferred to the suction chamber 1. 4, it is called a vacuum filtration device or a polluted liquid suction filtration device. There is.
