[0002] Oil quenching is a heat treatment method that heats metal materials to a certain temperature and then quickly immerses them in pre-prepared quenching oil for rapid cooling. The workpieces that have been oil quenched need to be cleaned. The use of a running water cleaning method will cause a large waste of water resources. Therefore, the workpieces are generally placed in a cleaning box for cleaning, and then the oil-water mixture in the cleaning box is centrally treated, but this still causes a waste of water resources.

[0003] Therefore, there is an urgent need for an oil-water separation device for heat treatment that can effectively separate the oil-water mixture. Utility Model Content

[0011] Optionally, oil flushing nozzles are provided at the corners of the slow flow area, the rapid flow area, and the reflow area.

[0025] like Figure 1-Figure 5 As shown, an oil-water separation device for heat treatment includes a cleaning box 1 provided with a cavity, and an oil-water separation mechanism is provided on the cleaning box 1;

[0026] A plurality of partitions 2 are arranged in the cavity of the cleaning box 1, and the partitions 2 divide the cavity into a primary slow flow chamber 3 and a secondary slow flow chamber 4 with the highest water levels decreasing in sequence. When the oil-water mixture in the primary slow flow chamber 3 overflows into the secondary slow flow chamber 4, a waterfall area is formed to prevent the oil-water from flowing back from the secondary slow flow chamber 4 to the primary slow flow chamber 3;

[0027] The oil-water separation mechanism includes a rotatable oil-water separation roller 5 and an oil collecting box 6 which can be axially attached to the outer periphery of the oil-water separation roller 5 on one side, wherein the lower half of the outer periphery of the oil-water separation roller 5 is in contact with the waterfall area along its axial direction, and relative to the flow direction of the oil-water mixture in the waterfall area, the movement direction of the oil-water separation roller 5 is opposite to the flow direction of the oil-water mixture, that is, when the oil-water separation roller 5 rotates, the floating oil on the surface of the oil-water mixture can adhere to the outer periphery of the oil-water separation roller 5, and when the floating oil on the oil-water separation roller 5 passes through the edge of the oil collecting box 6, the edge of the oil collecting box 6 scrapes off the floating oil on the oil-water separation roller 5 and collects it in the oil collecting box 6; therefore, when the oil-water mixture flows from the primary slow flow chamber 3 to the secondary slow flow chamber 4 and the oil-water separation roller 5 rotates continuously, the floating oil on the surface of the oil-water mixture can be continuously attached to the outer periphery of the oil-water separation roller 5, and the floating oil on the surface of the oil-water mixture can be collected in the oil collecting box 6 to achieve the effect of oil-water separation.

[0028] As mentioned above, in the technical solution, the floating oil in the oil-water mixture is a quenching oil commonly used in heat treatment, which can float on the surface of water and easily adhere to the surface of the oil-water separation roller 5, and the oil-water separation roller 5 can be driven by a power source such as a servo motor. The secondary slow flow chamber 4 can be divided into a plurality of secondary slow flow chambers with successively lowered high water levels by the partition 2 to form a plurality of waterfall areas, and an oil-water separation mechanism is provided in each waterfall area to increase the efficiency and effect of oil-water separation.

[0029] Further, such as Figure 3 As shown, the first-level slow flow chamber 3 includes a slow flow area 31, a rapid flow area 32, and a reflux area 33, the maximum water levels of which decrease successively. The reflux area 33 is connected to the second-level slow flow chamber 4. The width of the rapid flow area 32 gradually decreases along the flow direction of the oil-water mixture to increase the flow rate of the oil-water mixture from the rapid flow area 32 to the reflux area 33. In the present technical solution, the cavity of the cleaning box 1 is L-shaped, and the reflux area 33 is the turning point where the first-level slow flow chamber 3 is connected to the second-level slow flow chamber 4, so that the first-level slow flow chamber 3 and the second-level slow flow chamber 4 form a whirlpool structure in the reflux area 33, which can make the floating oil on the surface of the oil-water mixture concentrate and slowly flow to the second-level slow flow chamber 4, so that the floating oil can fully adhere to the outer peripheral surface of the oil-water separation roller 5, thereby increasing the oil-water separation effect.

[0030] The above, such as Figure 2 As shown, the corners of the slow flow area 31, the rapid flow area 32, and the reflow area 33 are all semicircular arc-shaped, which are used to guide the flow direction of the floating oil on the surface of the oil-water mixture. At the same time, in order to avoid the accumulation of oil in dead corners, the corners of the slow flow area 31, the rapid flow area 32, and the reflow area 33 are all provided with oil flushing nozzles 7, which can be connected to an external water source or an oil-water mixture to guide the direction of the floating oil by flushing the surface of the oil-water mixture.

[0031] In this embodiment, the cleaning box 1 is provided with a water outlet pipe 8 connected to the bottom of the second slow flow chamber 4 and a water inlet pipe assembly connected to the top of the head of the slow flow area 31, so as to allow the oil-water mixture to flow into the first slow flow chamber 3, and at the same time, to facilitate the centralized recycling of the water after oil-water separation from the water outlet pipe 8.

[0032] Further, such as Figure 1 As shown, the water inlet pipe assembly includes a first water inlet pipe 9 and a second water inlet pipe 10 connected to the first water inlet pipe 9 at one end. The first water inlet pipe 9 and the second water inlet pipe 10 are combined to form a Y-shaped structure. One end of the first water inlet pipe 9 can be connected to a water pump through a flange structure, and the other ends of the first water inlet pipe 9 and the second water inlet pipe 10 are connected to the first slow flow chamber 3. Among them, the oil-water mixture can be introduced into the first slow flow chamber 3 through the first water inlet pipe 9 and the second water inlet pipe 10 through the water pump, and the oil-water mixture is diverted to reduce the flow rate when it enters the first slow flow chamber 3; two solenoid valves 11 are respectively arranged on the first water inlet pipe 9 and the second water inlet pipe 10, and a Y-type filter 12 is arranged between the two solenoid valves 11 to ensure the fluidity of the oil-water mixture in the water inlet pipe and reduce blockage. At the same time, it is also convenient to remotely control the flow rate of the oil-water mixture in the first slow flow chamber 3 and the second slow flow chamber 4 through the solenoid valve 11.

[0033] As mentioned above, in order to accurately control the flow rate of the oil-water mixture through the solenoid valve 11, a float water level sensor 13 is provided on the surface of the oil-water mixture in the slow flow area 31, the rapid flow area 32, the reflux area 33 and the secondary slow flow chamber 4, and the float water level sensor 13 is electrically connected to the solenoid valve 11.

[0034] Working principle: the oil-water mixture can be introduced into the cavity of the cleaning box 1 through the water pump connected to the first water inlet pipe 9. Since the water level of the oil-water mixture in the first slow flow chamber 3 and the second slow flow chamber 4 has a certain drop, after a sufficient amount of the oil-water mixture is accumulated in the first slow flow chamber 3, the floating oil on the surface will overflow into the second slow flow chamber 4, and form a waterfall area at the junction of the first slow flow chamber and the second slow flow chamber 4. When the oil-water separation roller 5 rotates, the floating oil on the surface of the waterfall area can adhere to the outer periphery of the oil-water separation roller 5. When the floating oil on the oil-water separation roller 5 passes the edge of the oil collecting box 6, the edge of the oil collecting box 6 scrapes off the floating oil on the oil-water separation roller 5 and collects it in the oil collecting box 6. Therefore, the floating oil on the surface of the oil-water mixture can be continuously attached to the outer periphery of the oil-water separation roller 5, and the floating oil on the surface of the oil-water mixture can be continuously collected in the oil collecting box 6 to achieve the effect of oil-water separation.

[0035] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
