[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application.

[0025] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integral connection; can be mechanical connection, can also be electrical connection; can be direct connection, can also be indirect connection through intermediate medium, can be internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. The embodiments are written in a progressive manner.

[0026] As shown in Figures 1 to 5 A machine tool cooling water treatment equipment of the present application, comprising a water tank 1, an air inlet pipe 2 mounted at the bottom of the water tank 1 and a rotating drum 3 mounted at the lower side inside the water tank 1, a gas diffusion mechanism is arranged around the rotating drum 3, the air inlet pipe 2 communicates with the gas diffusion mechanism, the gas diffusion mechanism can diffuse the air discharged from the air inlet pipe 2 into water and form micro bubbles, the rotating drum 3 rotates in the water tank 1, a plurality of water outlets 5 are arranged on the outer wall of the rotating drum 3, and fan plates 4 are arranged on the outer wall of the rotating drum 3, a power mechanism and an overflow pipe 6 are arranged at the bottom of the water tank 1, the power mechanism is used to drive the rotating drum 3 to rotate, the overflow pipe 6 communicates with the inside of the rotating drum 3, and the water tank 1 and the overflow pipe 6 are fixedly connected through a supporting arm 20.

[0027] Specifically, the cooling water is discharged into the water tank 1 through the water inlet pipe on the back side of the water tank 1, and the cooling water in the water tank 1 flows into the rotating drum 3 through the water inlet 5 and overflows through the overflow pipe 6. This is the fluid process of water through the inside of the water tank 1. At the same time, the overflow pipe 6 can limit the water level of the cooling water in the water tank 1. In use, the rotating drum 3 is driven to rotate by the power mechanism, and the rotating drum 3 drives the multiple fan plates 4 on it to rotate. The fan plates 4 can stir the water in the water tank 1 to rotate and centrifugally move. At the same time, external air can be pumped into the air diffuser mechanism through the air inlet pipe 2. The air diffuser mechanism can discharge air into the water in the water tank 1 and make the air in the form of tiny bubbles. The bubbles float up to the water surface from the inside of the water tank 1. In the process of floating up, the bubbles can adsorb and float the impurities in the water. At the same time, due to the centrifugal movement of the water, the water pressure can push the bubbles towards the rotating drum 3, thereby forming a bubble layer in the vicinity of the rotating drum 3. The bubble layer can adsorb and treat the impurities in the water, thereby achieving the purpose of bubble filtration. This filtration method will not cause water flow blockage and affect the water flow property. At the same time, the centrifugally rotating water can push the larger impurities away from the rotating drum 3, thereby achieving the purification effect of the cooling water around the rotating drum 3. The water near the rotating drum 3 can enter the rotating drum 3 through the water inlet 5 and be discharged through the overflow pipe 6. The bubbles in the water tank 1 float to the water surface with impurities. Due to the centrifugal movement of the water, the impurities on the water surface can flow outward, thereby making the impurities on the water surface near the inner wall of the water tank 1 below the water surface. The smaller impurities are on the water surface near the inner wall of the water tank 1, so that the impurities are away from the rotating drum 3.

[0028] The impurities in the water are adsorbed and floated by the bubble curtain formed by the bubbles, thereby achieving the pneumatic filtration effect of the impurities. This avoids the blockage phenomenon in the traditional filtration method. Since the bubbles can also adsorb the tiny impurities, the filtration effect is strong, the treatment effect of the cooling water is improved, and the water flow property is not affected. The cooling water in the water tank 1 is simultaneously subjected to centrifugal rotation, so that the bubbles are in the vicinity of the rotating drum 3, avoiding the large-area diffusion of the bubbles and affecting the filtration effect of the water. The combination of the air floating effect of the bubbles and the centrifugal effect of the water can make the impurities in the water near the inner wall of the water tank 1, thereby making the impurities away from the rotating drum 3.

[0029] More preferably, the air diffuser mechanism comprises an air diffuser ring 7 sleeved outside the rotating drum 3. The cross-sectional shape of the air diffuser ring 7 is U-shaped, and the opening of the U-shaped is downward. One end of the U-shaped is connected with the inner wall bottom of the water tank 1, and the other end of the U-shaped forms an air exhaust gap with the inner wall bottom of the water tank 1. The end of the U-shaped is densely covered with teeth. The output end of the air inlet pipe 2 extends into the air diffuser ring 7.

[0030] Specifically, the air in the air inlet pipe 2 is discharged upward into the air diffuser ring 7, and since the opening of the air diffuser ring 7 faces downward, the air diffuser ring 7 can store air inside, and the water exerts pressure on the air in the air diffuser ring 7, and as the air inside the air diffuser ring 7 increases, the air pushes the liquid surface in the air diffuser ring 7 to gradually move down to the height position of the air exhaust gap, at which time the air can enter the water through the gap between the teeth and form bubbles, and since the water pressure near the air exhaust gap exerts pressure on the air, it can squeeze the large bubbles, and combined with the damage of the teeth to the bubbles, the air discharged into the water is formed into small bubbles, which can improve the air flotation area of the bubbles, thereby improving the filtering effect.

[0031] The air diffuser ring 7 has a simple structure, low manufacturing cost, and strong functionality.

[0032] More preferably, the air diffuser ring 7 rotates in the water tank 1, and the air diffuser ring 7 is connected to the rotating drum 3 through the connecting rod 8.

[0033] Specifically, due to the shape characteristics of the air diffuser ring 7, when the rotating drum 3 drives the air diffuser ring 7 to rotate through the connecting rod 8, the air inlet pipe 2 can always communicate with the inside of the air diffuser ring 7, and the rotating state of the air diffuser ring 7 can quickly diffuse the discharged bubbles, and the rotation of the air diffuser ring 7 can also cut the bubbles through the teeth, thereby reducing the volume of the bubbles.

[0034] More preferably, the water tank 1 is composed of a first conical barrel 18 located on the upper side and a second conical barrel 19 located on the lower side, the first conical barrel 18 and the second conical barrel 19 are in communication with each other, and the conical directions of the first conical barrel 18 and the second conical barrel 19 are opposite, the rotating drum 3 and the air diffuser ring 7 are located in the second conical barrel 19, and the bottom of the second conical barrel 19 is provided with an upward groove, thereby forming an annular groove on the lower side of the inner wall of the second conical barrel 19 to facilitate the storage of impurities, the lower side of the inner part of the second conical barrel 19 is in the form of a boss, and the air diffuser ring 7 and the rotating drum 3 are both arranged on the boss.

[0035] The bottom of the second conical barrel 19 is provided with a first motor 9, the output end of the first motor 9 extends into the rotating drum 3, and a transmission wheel 10 is arranged on the output end of the first motor 9, and the transmission wheel 10 is in transmission connection with the inner wall of the rotating drum 3.

[0036] Specifically, by adopting the structure of the combined water tank 1 of the first conical barrel 18 and the second conical barrel 19, the impurities floating on the water surface in the water tank 1 can be centrifuged in the first conical barrel 18 and gathered towards the inner conical surface of the first conical barrel 18, and the impurities in the water can be centrifuged to the vicinity of the inner wall of the second conical barrel 19 and moved to the annular groove-shaped inner part on the lower side of the inner wall of the second conical barrel 19, thereby gathering the impurities, thereby realizing the classification of the impurities.

[0037] The first motor 9 can drive the rotating drum 3 to rotate through the transmission wheel 10, thereby providing power for the rotating drum 3.

[0038] More preferably, the water gap 5 is inclined, and the inclination direction thereof is towards the direction away from the axis of the rotating drum 3 and inclined upwards.

[0039] Specifically, by inclining the water gap 5 and limiting the inclination direction thereof, the air bubbles in the water cannot enter the water gap 5 due to the buoyancy when the water in the water tank 1 enters the water gap 5, thereby realizing the separation effect of air bubbles and water and avoiding the air bubbles carrying impurities into the rotating drum 3.

[0040] More preferably, the shape of the fan plate 4 is composed of a vertical plate on the upper side and a spiral plate on the lower side, and the spiral plate is fixed on the rotating drum 3, the rotating drum 3 is provided with a support column 11 on the top, and the vertical plate is fixed on the support column 11.

[0042] More preferably, the first conical barrel 18 is provided with a debris removal channel 12 horizontally communicated on the side wall, the debris removal channel 12 is provided with a triangular platform 13, the surface of the triangular platform 13 facing the first conical barrel 18 is provided as an arc surface, the surface of the triangular platform 13 away from the first conical barrel 18 is provided as an inclined surface, a rotating shaft 14 is rotatably arranged in the debris removal channel 12, a plurality of push plates 15 are arranged on the outer wall of the rotating shaft 14, a second motor 16 is arranged on the outer wall of the debris removal channel 12, and the output end of the second motor 16 is in transmission connection with the rotating shaft 14.

[0043] Specifically, the impurities floating on the liquid surface in the first conical barrel 18 can enter the debris removal channel 12 due to the centrifugal motion, the triangular platform 13 blocks the water in the debris removal channel 12, the second motor 16 can drive the rotating shaft 14 and the plurality of push plates 15 to rotate, the push plates 15 can push the floating impurities in the debris removal channel 12 to move to the inclined surface on the triangular platform 13 through the arc surface on the triangular platform 13, so as to make the impurities discharged along the inclined surface of the triangular platform 13.

[0044] More preferably, the annular groove on the lower side of the second conical barrel 19 is provided with a surrounding fence 17, and the cross section of the surrounding fence 17 is inclined.

[0045] Specifically, by arranging the surrounding fence 17, the impurities collected in the annular groove on the lower side of the second conical barrel 19 can be blocked to avoid the impurities flowing randomly with the water flow.

[0046] The above merely describes the preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present application, and these improvements and modifications should also be considered as the protection scope of the present application.
