[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figures 1 to 5 The utility model provides a technical solution: a grinding ball grinding coolant recovery device with a filtering structure, comprising a coolant tank 1 and a sealing cover 3 detachably mounted on the top of the coolant tank 1. In order to allow the sealing cover to be stably installed, a card slot 2 can be provided on the top of the coolant tank 1. When the bottom of the sealing cover 3 is placed on the card slot 2, it can be fixed. At the same time, the sealing cover 3 and the coolant tank 1 are connected by a lock, and the lock is preferably a hasp. A feeding port 4 is provided on the top of the sealing cover 3, and a sealing cover is provided on the top of the feeding port 4. Coolant can be added to the coolant tank 1 through the feeding port 4. In order to facilitate the observation of the height of the coolant inside the coolant tank, a liquid level gauge connected to the coolant tank 1 can be installed on the side of the coolant tank 1, and the liquid level gauge is preferably a magnetic flap liquid level gauge.
[0025] like Figure 1 and Figure 2 As shown, a drain valve is provided at the bottom of the side of the coolant tank 1, and the drain valve can discharge the dirt inside the coolant tank 1 when cleaning it, thus facilitating cleaning.
[0026] like Figure 2 As shown, a liquid inlet 5 is provided on the top of the sealing cover 3, a liquid outlet 10 is provided on the side of the coolant tank 1, and a material tank 13 is provided inside the coolant tank 1. A filter screen is provided at the bottom of the material tank 13, and the material tank 13 can be connected to the outside through the filter screen. In actual use, the material tank 13 is located at the top of the coolant tank 1;
[0027] The liquid inlet 5 is connected to the coolant outlet of the ball grinding machine through a pipeline. The liquid inlet 5 is located above the filter screen. The coolant falls on the filter screen of the equalizing tank 13. Then the liquid outlet 10 is connected to the coolant inlet of the ball grinding machine through a pipeline. A delivery pump can be installed on the pipeline connected to the liquid inlet 5 and the pipeline connected to the liquid outlet 10. The delivery pump can quickly drain the coolant in the machine tool processing process into the coolant tank 1, and at the same time, the delivery pump can also deliver the coolant in the coolant tank 1 to the machine tool again;
[0028] Specifically, during the cutting or grinding process of the machine tool, the coolant is continuously sprayed at the grinding part of the machine tool. The coolant gathers inside the machine tool and flows into the liquid inlet 5 through the pipeline, and then falls on the filter screen in the equalizing trough 13 from the liquid inlet 5. The filtered coolant will be concentrated in the coolant tank 1, and then circulate to the machine tool again through the liquid outlet 10. The coolant entering the coolant tank 1 can be kept clean at all times by the set filter screen, avoiding the entry of debris into the coolant tank 1.
[0029] In the present invention, further improvements are made to the equal trough 13, such as Figure 3 and Figure 4 As shown, the bottom of the material tank 13 is an inclined surface 14 inclined upward, so that the bottom of the material tank 13 is sloped, and the top edge of the material tank 13 is sealed with the inner wall of the sealing cover 3, so that when the coolant falls into the material tank 13, the coolant can fall along the filter screen at the bottom of the material tank 13;
[0030] The end of the material trough 13 located at the top of the inclined surface 14 is connected to the side wall of the inner cavity of the sealing cover 3, and the bottom of the material trough 13 is an arc-shaped structure. Figure 1 and Figure 2 As shown, a discharge channel 7 coaxial with the arc structure is provided on the outer side of the equalizing trough 13 and the two are connected, a spiral shaft 17 is coaxially provided at the bottom of the equalizing trough 13, the top of the spiral shaft 17 is placed in the discharge channel 7, the upper end of the spiral shaft 17 is rotatably connected to the end of the discharge channel 7, and the lower end is rotatably connected to the end of the equalizing trough 13, a driving motor 8 connected to the spiral shaft 17 is provided at the top of the discharge channel 7, and a drop port 9 is provided below the discharge channel 7;
[0031] like Figure 3 and Figure 4 As shown, a first opening 11 is provided at the arc structure, and the filter screen is installed in the first opening 11. The spiral blades 16 on the surface of the spiral shaft 17 are matched with the filter screen and the discharge channel 7, so when the driving motor 8 rotates, the spiral shaft 17 can be driven to rotate. During the rotation, the metal debris remaining on the filter screen is transported to the discharge channel 7 through the spiral blades, and finally the metal debris falls through the drop port 9. A material container can be placed below the drop port 9 to allow the debris to fall into the container.
[0032] Further, such as Figure 4 As shown, a second opening 12 is provided on the end face of the equal material trough 13 at the bottom of the inclined surface 14 and on other side faces of the equal material trough 13, and a filter is provided in the second opening 12. The coolant flowing into the equal material trough 13 can not only fall through the first opening 11, but also fall through the second opening 12. The second opening 12 increases the flow rate of the coolant.
[0033] In order to facilitate the inspection of the spiral shaft 17, Figure 1 As shown, an inspection port 6 is also provided on the top of the sealing cover. The inspection port 6 is located above the material tank 13. The inspection port 6 is sealed by a detachable sealing plate 18. The liquid inlet 5 is provided on the sealing plate 18. The edge of the inspection port 6 is fastened to the sealing plate 18 by bolts.
[0034] In order to prevent the screw shaft from bringing the coolant out of the coolant tank 1, the screw blade 16 is also improved. Figure 4 and Figure 5 As shown, a plurality of flow openings 15 are provided along the surface of the spiral blade 16, and a filter is provided in the flow opening 15, so that when the spiral blade 16 lifts the debris, the coolant on the surface of the spiral blade 16 will flow back into the coolant tank 1 through the flow opening 15, thereby preventing the coolant from flowing out of the blanking port 9.
