[0002] Copper alloy cutting fluid preparation wastewater is the wastewater generated in the process of producing copper alloy cutting fluid, which contains a variety of chemical additives, surfactants, mineral oils and metal ions.

[0003] When treating wastewater for the preparation of copper alloy cutting fluid, it is necessary to remove floating oil and dispersed oil in the wastewater to prevent the oil from adhering to the surface of the sewage treatment equipment, such as pipes, gratings, sedimentation tanks, etc., which will reduce the treatment efficiency and service life of the equipment. Therefore, when treating wastewater for the preparation of copper alloy cutting fluid, the treatment of floating oil and dispersed oil is more important.

[0014] Preferably, a limiting portion is fixedly installed on the end of the movable shaft located in the fixed sleeve, and a spring is movably installed in the fixed sleeve, and the spring is located between the L-shaped limiting strip and the V-shaped mounting plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Inject the sewage generated by the copper alloy cutting fluid into the sewage treatment tank, put the reagent that reacts with the sewage into the sewage treatment tank, adjust the rotating shaft and the V-shaped mounting plate, rotate the rotating shaft and the V-shaped mounting plate, let the rotating shaft and the V-shaped mounting plate be in a horizontal state, install the separator in the installation positioning plate, and put one end of the separator through the installation positioning plate into the corresponding threaded mounting groove. The separator is installed in the threaded mounting groove by rotating the separator to fix the structure composed of the rotating shaft, the V-shaped mounting plate and the mounting positioning plate. At this time, the V-shaped mounting plate needs to be fixed. To adjust the support wheel at the other end of the plate, the support wheel needs to be adjusted to a vertical state. When adjusting the angle of the support wheel, pressure is applied to the wheel mounting frame and the support wheel to allow the movable shaft to move in the fixed sleeve. The limiting portion outside one end of the movable shaft located in the fixed sleeve moves in the fixed sleeve. When the limiting portion moves in the fixed sleeve, the limiting portion applies pressure to the spring, and the spring is deformed. The deformation of the spring generates a reverse elastic force for resetting the limiting portion. When the movable shaft rotates, it drives the L-shaped limiting strip to move outside the fixed sleeve, and the L-shaped positioning frame limits the movement of the L-shaped limiting strip. At the same time, the pressure exerted by the spring on the limiting part can assist in stopping the movable rotating shaft, the wheel mounting frame and the supporting wheel after rotation. When the piston rod in the driving oil cylinder is lifted or lowered, pressure is exerted on the supporting plate, thereby driving the rotating sleeve to lift or lower. When the rotating sleeve is lifted or lowered, the V-shaped mounting plate is driven to lift or lower. When the V-shaped mounting plate is lifted or lowered, the supporting wheel at the other end of the V-shaped mounting plate contacts the inner wall of the sewage treatment tank, and the supporting wheel rolls up and down. The lifting or lowering of the V-shaped mounting plate is assisted by the supporting wheel. When the V-shaped mounting plate is lifted or lowered, pressure can be exerted on the sewage at the position of the V-shaped mounting plate in the sewage treatment tank, driving the sewage and reagent at this position to mix, thereby improving the mixing effect of the sewage and the reagent, and preventing insufficient contact between the application and the sewage. At the same time, after the V-shaped mounting plate is raised to a sufficient height, the driven gear contacts the driving gear, and the output shaft of the driving motor drives the driven gear to rotate. When the driven gear and the rotating sleeve rotate, the V-shaped mounting plate can be driven to rotate, changing the position of the V-shaped mounting plate in the sewage treatment tank, so that the V-shaped mounting plate can be lifted or lowered at different positions in the sewage treatment tank, thereby achieving the mixing of sewage and reagents at different positions in the sewage treatment tank, thereby improving the mixing effect of the sewage;

[0017] By rotating the rotating shaft and the V-shaped mounting plate, the angles of the rotating shaft and the V-shaped mounting plate are changed, and the rotating shaft and the V-shaped mounting plate are in a vertical state. The mounting positioning plate on the V-shaped mounting plate is aligned with the threaded mounting groove at the corresponding position, and the rotating shaft and the V-shaped mounting plate adjusted to the vertical state are fixed by the dividing strip. At the same time, the supporting wheel at the other end of the V-shaped mounting plate is adjusted so that the supporting wheel at this position is in a horizontal state. By applying pressure to the movable rotating shaft, the wheel mounting frame and the supporting wheel, the movable rotating shaft and the limiting part are moved in the fixed sleeve. The movable rotating shaft and the limiting part are extended and contracted in the fixed sleeve and pressure is applied to the spring. The spring is deformed under pressure. After the spring is deformed, a reverse elastic force is generated for resetting the movable rotating shaft and the limiting part. At the same time, the L-shaped limiting strip is located in another L-shaped positioning frame on the fixed sleeve, thereby realizing the change of the angle of the supporting wheel. When the supporting wheel is in a horizontal state, the height of the V-shaped mounting plate is adjusted to allow the driven gear to mesh with the driving gear at this position. At the same time, the height of the V-shaped mounting plate corresponds to the height of the sewage treatment plant. The height of the liquid level in the sewage treatment pool, the floating oil and dispersed oil in the sewage are located on the liquid surface, and the driving motor output shaft drives the driving gear to rotate, thereby driving the driven gear to rotate. When the driven gear rotates outside the inner rotating shaft and the limit ring, the rotating sleeve drives the V-shaped mounting plate to move on the liquid surface in the sewage treatment pool, and the V-shaped mounting plate contacts the floating oil and dispersed oil on the liquid surface. When the V-shaped mounting plate is in a vertical state, the floating oil and dispersed oil are collected, and the collected floating oil and dispersed oil move along the V-shaped mounting plate and the dividing strip and contact the oil absorption strip. The oil absorption strip collects the floating oil and dispersed oil, thereby reducing the influence of oil substances on subsequent sewage treatment. At the same time, the oil absorption strip is drawn out of the fixing bolt to realize the cleaning of the floating oil and dispersed oil on the oil absorption strip, and the mixing of sewage and reagent is realized by the lifting and lowering of the V-shaped mounting plate in a horizontal state, and the collection of floating oil and dispersed oil is realized by the rotation of the V-shaped mounting plate in a vertical state. According to different situations, the V-shaped mounting plate is adjusted to perform work in different situations, thereby greatly improving the sewage treatment effect.

The vertical section of the V-shaped mounting plate 15 is V-shaped. When the V-shaped mounting plate 15 is horizontal, the sewage in the sewage treatment tank 1 will be hit during the up and down movement of the V-shaped mounting plate 15, thereby assisting the mixing of the sewage and the reagent in the sewage treatment tank 1. When the V-shaped mounting plate 15 is vertical, the V-shaped mounting plate 15 will contact the liquid surface in the sewage treatment tank 1 during the rotation of the V-shaped mounting plate 1 in the sewage treatment tank 1. The floating oil and dispersed oil contained on the liquid surface will contact the V-shaped mounting plate 15, thereby realizing the collection of the floating oil and dispersed oil by the V-shaped mounting plate 15.

A dividing strip 17 is threadedly installed in the threaded mounting groove 1301, and the end of the dividing strip 17 passes through the mounting positioning plate 16 and is threadedly connected to the threaded mounting groove 1301. The positions of the mounting positioning plate 16 and the threaded mounting groove 1301 correspond to each other. The fixing of the mounting positioning plate 16 is achieved by fixing the dividing strip 17 in the mounting positioning plate 16 and the threaded mounting groove 1301, thereby fixing the rotating shaft 14 and the V-shaped mounting plate 15 after rotation. The two threaded mounting grooves 1301 on the mounting positioning plate 16 and the assembly seat 13 correspond to each other, thereby controlling the rotation angle of the V-shaped mounting plate 15, realizing the control of the horizontal state and the vertical state of the V-shaped mounting plate 15, and achieving different control effects.

[0037] Two threaded mounting grooves 1301 are provided on the assembly seat 13, and the arc-shaped circular angle corresponding to the two threaded mounting grooves 1301 is 90°. Through the position setting of the threaded mounting grooves 1301, it is ensured that after the angle of the rotating shaft 14 and the V-shaped mounting plate 15 is adjusted, the V-shaped mounting plate 15 must be in a horizontal state and a vertical state to prevent the rotating shaft 14 and the V-shaped mounting plate 15 from rotating.

[0038] A guide groove 1501 is provided on the V-shaped mounting plate 15, and two dividing bars 17 are provided in the guide groove 1501. The two dividing bars 17 are symmetrically arranged in the guide groove 1501, and the guide groove 1501 is separated by the dividing bars 17.

The floating oil and dispersed oil flowing through the guide groove 1501 are in contact with the oil absorption strip 19. The oil absorption strip 19 is a strip made of sponge material. Through the porous structure of the sponge, the oil absorption strip 19 can absorb a large amount of oil substances, thereby reducing the impact of the oil substances on subsequent sewage treatment.

[0040] A fixed sleeve 21 is fixedly installed on one end of the V-shaped mounting plate 15 away from the assembly seat 13, and a movable shaft 22 is rotatably connected in the fixed sleeve 21. When the movable shaft 22 rotates in the fixed sleeve 21, the state of the support wheel 24 is changed, so that the support wheel 24 is in a horizontal state and a vertical state. The support wheel 24 has a mode of sliding horizontally on the inner wall of the sewage treatment tank 1, and the support wheel 24 also has a mode of sliding vertically on the inner wall of the sewage treatment tank 1. According to the working state of the V-shaped mounting plate 15, the state of the support wheel 24 is adjusted, and the end of the movable shaft 22 away from the fixed sleeve 21 is fixedly connected to a wheel mounting frame 23, and the wheel mounting frame 23 is rotatably connected to the support wheel 24, and the support wheel 24 is in contact with the inner wall of the sewage treatment tank 1.

[0041] Two L-shaped positioning frames 25 are fixedly installed on one side of the V-shaped mounting plate 15 close to the fixed sleeve 21, and an L-shaped limit strip 26 is fixedly installed on the outer wall of the movable rotating shaft 22. The L-shaped limit strip 26 is movably engaged in the L-shaped positioning frame 25, and the L-shaped positioning frame 25 limits the movement of the L-shaped limit strip 26. The L-shaped limit strip 26 is fixedly installed on the outer wall of the movable rotating shaft 22, and the L-shaped limit strip 26 is driven to move between the two L-shaped positioning frames 25 through the rotation of the movable rotating shaft 22. The L-shaped positioning frame 25 controls the rotation angle of the movable rotating shaft 22 and the support wheel 24, so as to realize the control of the support wheel 24 in the horizontal and vertical shapes.

[0042] The arc formed by the two L-shaped positioning frames 25 has a central angle of 90°, and the two L-shaped positioning frames 25 are centrally symmetrically arranged. The L-shaped positioning frames 25 are L-shaped, and the end of the L-shaped limiting strip 26 located outside the fixed sleeve 21 is limited by the L-shaped positioning frames 25 to achieve the limitation of the rotation angle of the movable shaft 22.

[0043] A limiting portion 27 is fixedly installed on the end of the movable rotating shaft 22 located in the fixed sleeve 21. The movable rotating shaft 22 and the limiting portion 27 form a T-shaped rotating structure. The limiting portion 27 is used for limiting, and the movable rotating shaft 22 is used for rotation and connection. A spring 28 is movably installed in the fixed sleeve 21. The spring 28 is located between the L-shaped limiting strip 26 and the V-shaped mounting plate 15. The spring 28 applies pressure to the limiting portion 27. The pressure applied by the spring 28 to the side of the limiting portion 27 ensures that the limiting portion 27 stops after rotation.

[0044] Working principle:

[0045] Step 1: Make the wastewater generated by the copper alloy cutting fluid and inject it into the wastewater treatment tank 1, put the reagent that reacts with the wastewater into the wastewater treatment tank 1, adjust the rotating shaft 14 and the V-shaped mounting plate 15, rotate the rotating shaft 14 and the V-shaped mounting plate 15, let the rotating shaft 14 and the V-shaped mounting plate 15 be in a horizontal state, install the partition bar 17 in the mounting positioning plate 16, one end of the partition bar 17 passes through the mounting positioning plate 16 and is placed in the corresponding threaded mounting groove 1301, and the partition bar 17 is installed in the threaded mounting groove 1301 by rotating the partition bar 17, so as to realize the fixation of the structure composed of the rotating shaft 14, the V-shaped mounting plate 15 and the mounting positioning plate 16. At this time, it is necessary The support wheel 24 at the other end of the V-shaped mounting plate 15 is adjusted. The support wheel 24 needs to be adjusted to a vertical state. When adjusting the angle of the support wheel 24, pressure is applied to the wheel mounting frame 23 and the support wheel 24 to allow the movable shaft 22 to move in the fixed sleeve 21. The limiting portion 27 outside one end of the movable shaft 22 located in the fixed sleeve 21 moves in the fixed sleeve 21. When the limiting portion 27 moves in the fixed sleeve 21, the limiting portion 27 applies pressure to the spring 28, and the spring 28 is deformed. The deformation of the spring 28 generates a reverse elastic force for resetting the limiting portion 27. When the movable shaft 22 rotates, it drives the L-shaped limiting strip 26 to move outside the fixed sleeve 21, and the L-shaped positioning frame 25 The movement of the L-shaped limit strip 26 is limited, and at the same time, the pressure exerted by the spring 28 on the limit part 27 can assist in stopping the movable rotating shaft 22, the wheel mounting frame 23 and the supporting wheel 24 after rotation. When the piston rod 7 in the driving cylinder 6 is lifted or lowered, it will exert pressure on the supporting plate 8, thereby driving the rotating sleeve 11 to lift or lower. When the rotating sleeve 11 is lifted or lowered, it will drive the V-shaped mounting plate 15 to lift or lower. When the V-shaped mounting plate 15 is lifted or lowered, the supporting wheel 24 at the other end of the V-shaped mounting plate 15 contacts the inner wall of the sewage treatment tank 1, and the supporting wheel 24 rolls up and down. The lifting of the V-shaped mounting plate 15 is assisted by the supporting wheel 24. When the V-shaped mounting plate 15 is lifted or lowered, it can The sewage at the position is pressurized, driving the sewage and reagent at the position to mix, thereby improving the mixing effect of the sewage and the reagent and preventing insufficient contact between the application and the sewage. At the same time, after the V-shaped mounting plate 15 is raised to a sufficient height, the driven gear 12 contacts the driving gear 4, and the output shaft of the driving motor 3 drives the driven gear 12 to rotate. When the driven gear 12 and the rotating sleeve 11 rotate, the V-shaped mounting plate 15 can be driven to rotate, changing the position of the V-shaped mounting plate 15 in the sewage treatment tank 1. In this way, the V-shaped mounting plate 15 can be raised and lowered at different positions in the sewage treatment tank 1, thereby realizing the mixing of sewage and reagents at different positions in the sewage treatment tank 1, thereby improving the mixing effect of the sewage.

[0046] Step 2: By rotating the rotating shaft 14 and the V-shaped mounting plate 15, the angles of the rotating shaft 14 and the V-shaped mounting plate 15 are changed, so that the rotating shaft 14 and the V-shaped mounting plate 15 are in a vertical state, the mounting positioning plate 16 on the V-shaped mounting plate 15 is aligned with the threaded mounting groove 1301 at the corresponding position, and the rotating shaft 14 and the V-shaped mounting plate 15 adjusted to the vertical state are fixed by the partition bar 17, and the support wheel 24 at the other end of the V-shaped mounting plate 15 is adjusted so that the support wheel 24 at this position is in a In a horizontal state, by applying pressure to the movable shaft 22, the wheel mounting frame 23 and the supporting wheel 24, the movable shaft 22 and the limiting portion 27 are moved in the fixed sleeve 21, and the movable shaft 22 and the limiting portion 27 are extended and retracted in the fixed sleeve 21 and pressurize the spring 28, and the spring 28 is deformed under pressure. After the spring 28 is deformed, a reverse elastic force is generated for resetting the movable shaft 22 and the limiting portion 27. At the same time, the L-shaped limiting strip 26 is located in another L-shaped positioning frame 25 on the fixed sleeve 21, thereby realizing the support wheel 2 4 angle changes, when the support wheel 24 is in a horizontal state, adjust the height of the V-shaped mounting plate 15 to allow the driven gear 12 to mesh with the driving gear 4 at this position. At the same time, the height of the V-shaped mounting plate 15 corresponds to the height of the liquid level in the sewage treatment tank 1. The floating oil and dispersed oil in the sewage are located on the liquid surface. The output shaft of the driving motor 3 drives the driving gear 4 to rotate, thereby driving the driven gear 12 to rotate. When the driven gear 12 rotates outside the inner rotating shaft 9 and the limit ring 10, the rotating sleeve 11 will drive the V-shaped mounting plate 15 in the sewage treatment tank. The V-shaped mounting plate 15 moves on the liquid surface in the water treatment pool 1, and contacts with the floating oil and dispersed oil on the liquid surface. When the V-shaped mounting plate 15 is in a vertical state, the floating oil and dispersed oil are collected. The collected floating oil and dispersed oil move along the V-shaped mounting plate 15 and the dividing strip 17, and contact with the oil absorbing strip 19. The oil absorbing strip 19 collects the floating oil and dispersed oil to reduce the influence of oil substances on subsequent sewage treatment. At the same time, the oil absorbing strip 19 is drawn out from the fixing bolt 20 to realize the cleaning of the floating oil and dispersed oil on the oil absorbing strip 19.
