Detailed Implementation
[0035] The present invention will be further described below with reference to the embodiments, but this should not be construed as limiting the present invention.
[0036] Embodiments of this utility model
[0037] A device for settling and recovering grinding coolant for aero-engine parts, as shown in the attached document. Figures 1-5 As shown, it includes a conventional sedimentation tank 1, a drain pipe 2 connected inside the sedimentation tank 1, and a drain pump 3 installed on the drain pipe 2; the top of the sedimentation tank 1 is provided with a drain hole 4, and a pre-sedimentation device is provided around the drain hole 4.
[0038] The pre-sedimentation device includes a square frame 5. The bottom of the square frame 5 is tightly connected to the top of the sedimentation tank 1 by welding. A first partition 6 is provided in the middle of the square frame 5 along the length direction. One end of the first partition 6 is connected to the inner side of the square frame 5, and the other end is not connected, so that the first partition 6 divides the square frame 5 into a U-shaped flow channel 7. One end of the U-shaped flow channel 7 is the sewage discharge end 13, and the other end is connected to the drain hole 4.
[0039] In use, the device of this embodiment is placed next to the lathe, and the lathe coolant drain pipe is led to the top of the sewage inlet 13. After the coolant flows into the U-shaped flow channel 7 through the sewage inlet 13, it flows slowly and settles under the action of the U-shaped flow channel 7. When the coolant reaches the drain hole 4, most of the metal shavings have settled and will not enter the sedimentation tank 1. The coolant in the sedimentation tank 1 can be recycled under the action of the drain pipe 2 and the drain pump 3.
[0040] Further implementation, for example, is attached. Figures 1-5 As shown, a stepped baffle 8 is also provided in the U-shaped flow channel 7 between the drain hole 4 and the sewage discharge end 13.
[0041] In this embodiment, the height of the stepped baffle 8 is lower than that of the square frame 5 and the first partition 6. The metal shavings are first forced to settle on the upstream side of the stepped baffle 8, and a small amount of metal shavings flowing with the coolant enter the downstream side of the stepped baffle 8 to continue settling, which can improve the settling efficiency.
[0042] Further implementation, for example, is attached. Figures 1-5 As shown, the drain hole 4 is a convex drain hole, and its top edge is higher than the top surface of the sedimentation tank 1.
[0043] The drain hole 4 of the embodiment is actually a pipe upwardly protruding with a height of 5-10 cm, and the metal chips cannot directly enter the drain hole 4 when reaching the periphery of the drain hole 4, and the coolant can only enter the sediment tank 1 by climbing over the end edge of the drain hole 4 after accumulating to a certain height.
[0044] Further embodiments are shown in the drawings Figures 1-5 As shown, the periphery of the drain hole 4 is further provided with a mud blocking frame 10, and the lower side of the mud blocking frame 10 is provided with a water passing hole 11, and the water passing height of the water passing hole 11 is lower than the protruding height of the drain hole 4.
[0045] The mud blocking frame 10 of the embodiment is a square frame directly placed at the periphery of the water passing hole 11, and under normal circumstances, the coolant flows into the interior of the mud blocking frame 10 from the water passing hole 11, and accumulates to a certain height to flow into the drain hole 4, but when the accumulation height of the metal chips outside the mud blocking frame 10 is higher than the water passing hole 11, the water passing hole 11 will be blocked, at this time, neither the metal chips nor the coolant can enter the interior of the mud blocking frame 10, and the metal chips can be prevented from further accumulating to flow into the drain hole 4, at this time, the metal chip sediment in the pre-sediment device needs to be cleaned.
[0046] Further embodiments are shown in the drawings Figures 1-5 As shown, the sewage discharge end 13 is further provided with a buffer baffle 9.
[0047] The buffer baffle 9 of the embodiment is an inclined baffle, and the coolant sewage discharged by the lathe directly falls on the buffer baffle 9 to play a buffering role.
[0048] Further embodiments are shown in the drawings Figures 1-5 As shown, the bottom of the drain pipe 2 is provided with a filter screen cover 12. The filter screen cover 12 is a conventional filter screen, which further prevents the metal chips from entering the drain pipe 2.
[0049] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
