Description

Technical Field

[0001] This invention relates to the field of steel water quenching technology, and in particular to an annealing furnace water quenching device. Background Technology

[0002] Annealing furnaces are a process used in semiconductor device manufacturing, involving heating multiple semiconductor wafers to influence their electrical properties. Heat treatments are designed for different effects. Heating wafers can activate dopants. Water quenching uses water as a quenching agent and has the advantage of rapid cooling in high-temperature zones (550℃~650℃). However, it also cools rapidly in low-temperature zones (200℃~300℃), potentially causing significant structural stress. Water quenching involves immersing a hot object in water, heating it until red-hot, and then immersing it again repeatedly to improve rigidity.

[0003] In the prior art, patent document CN208748176U discloses a continuous annealing furnace water quenching device, belonging to the technical field of cold-rolled strip steel equipment in the metallurgical industry. The technical solution is as follows: the top of the water quenching tank has a strip steel inlet and outlet, the bottom of the water quenching tank has a drain valve, water quenching rollers are installed inside the water quenching tank, a steam exhaust pipe is installed in the water quenching tank, cleaning nozzles are installed on both sides and above the water quenching rollers, one end of a circulating water pipe is connected to the lower part of the water quenching tank, and the other end of the circulating water pipe is connected to the upper part of the water quenching tank. Spray nozzles are installed on both sides of the strip steel outlet at the top of the water quenching tank. The beneficial effects of this utility model are: it can discharge steam in a timely manner, ensuring the stability of the dew point inside the furnace; it enables cleaning of the water quenching rollers and the water quenching tank without opening the tank, ensuring the cooling effect of the strip steel.

[0004] The existing technology has the following problems: When the strip steel enters the water quenching tank, the iron powder adsorbed on the surface of the strip steel will enter the water in the water quenching tank, and then be deposited on the bottom of the tank and the surface of the water quenching rollers, which cannot be removed. This causes an increase in the conductivity of the water. The iron accumulated in the water will oxidize and be adsorbed on the surface of the strip steel. When the water source is extracted, it needs to be filtered. However, the iron oxide will be pushed by the water source and gradually adhere to the surface of the filter screen. If it is not cleaned in time, the iron oxide will gradually adhere to the surface of the filter screen and will be difficult to clean later. Moreover, when water quenching comes into contact with high-temperature steel, the temperature of the surface in contact with the water source will gradually rise, while the water temperature at the periphery of the water quenching tank will be lower than the center temperature, resulting in inconsistent internal temperatures. During secondary water quenching, the temperature difference will cause differences in the cooling efficiency on the surface of the steel, resulting in differences in the toughness of the steel surface. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem that in the prior art, the high temperature of the steel surface during water quenching will rapidly cool down and produce iron oxide. The detached iron oxide will accumulate on the bottom surface of the water quenching tank and is not easy to clean after filtration. Moreover, the temperature of the water source surface during water quenching will vary due to the different contact surfaces of the steel. The temperature difference will lead to differences in the cooling rate and efficiency of the steel surface, resulting in differences in toughness.

[0006] To solve the above-mentioned technical problems, the present invention provides an annealing furnace water quenching device.

[0007] In one embodiment of the present invention, it includes:

[0008] Chip guide pipe fixed to the bottom surface of the water quenching tank.

[0009] A cooling pool fixed to the surface of the other end of the chip guide water pipe.

[0010] The return pipe is fixed to the top edge of the right side of the cooling pool.

[0011] A lower vibrating chip removal unit is movably sleeved on the inner surface of the cooling pool. The lower vibrating chip removal unit includes a filter plate movably sleeved on the inner wall of the cooling pool. A water mixing unit is movably sleeved on the inner wall of the cooling pool at the top edge of the filter plate. The water mixing unit includes a mixing mesh plate. An upper inclined settling unit is fixedly connected to the bottom inner wall of the cooling pool. The upper inclined settling unit includes an inclined plate. At the same time, it works with the water guide inclined pipe on the inner surface of the inner liner cavity to guide the water source into the interior of the water quenching pool. Through the contraction arc of the arc funnel, the concentrated iron oxide is injected into the interior of the chip guide water pipe. Then, in conjunction with the cooling pool to filter the water source, when the red-hot steel is hoisted into the interior of the water quenching pool, the water source filtered inside the cooling pool is re-injected into the interior of the inner liner cavity through the return pipe.

[0012] In one embodiment of the present invention, a hydraulic compression driving unit is provided on the inner surface of the mixing mesh plate. The hydraulic compression driving unit includes a snap-fit ​​strip, a driving blade and a stirring blade. An elastic driving impact unit is movably sleeved on the inner surface of the filter plate. The elastic driving impact unit includes an arc-shaped horn, an elastic strip and an elastic filter screen.

[0013] In one embodiment of the present invention, a water passage hole is formed on the outer surface of the filter plate, and a snap-fit ​​strip is fixedly connected to the upper and lower edges of the water passage hole. A limiting sleeve is fixedly connected to one end of the snap-fit ​​strip, and a sliding rod is movably sleeved on the inner surface of the limiting sleeve. The top end of the sliding rod is fixedly connected to the middle of the bottom of the arc-shaped horn.

[0014] In one embodiment of the present invention, one end of the elastic strip is fixedly connected to the bottom surface of the snap-fit ​​strip, and the other end of the elastic strip is fixedly connected to the bottom outer surface of the slide rod. Utilizing the change in the impact force of the water source during impact, the elastic strip pulls the slide rod back, causing the bottom end of the slide rod to strike the surface of the elastic filter screen. This impacts and dislodges some fine iron oxide adhering to the bottom surface of the elastic filter screen, reducing the amount of residual iron oxide on the surface of the elastic filter screen. Limiting grooves are provided on the bottom two side edges of the filter plate. The two side surfaces of the elastic filter screen are movably fitted onto the inner surface of the limiting grooves, and the bottom surface of the slide rod movably overlaps the top surface of the elastic filter screen. When some fine iron oxide flows upward, it is filtered by the elastic filter screen, and the filtered water flows upward through the water passage holes on the surface of the filter plate.

[0015] In one embodiment of the present invention, a compressed water hole is provided on the outer surface of the mixing mesh plate. Low-temperature water is pumped into the cooling tank through a water pump, and the water is atomized and discharged through a honeycomb mesh pipe, so that it mixes with the water that has absorbed heat. When the water passes through the surface of the mixing mesh plate, it pushes the internal pushing blades. The outer surface of the second snap-fit ​​strip is fixedly connected to the inner surface of the compressed water hole. A rotating rod is movably sleeved on one end of the second snap-fit ​​strip, thereby driving the rotating rod to rotate on the inner surface of the second snap-fit ​​strip. When the stirring blades rotate, they stir the low-temperature water and hot water, mixing them together, thereby reducing the temperature of the water. When the water is re-poured into the water quenching tank, it will mix with the water that has absorbed heat, and then the rotating water will mix them together again, reducing the temperature of the water and maintaining a constant temperature of the water to the greatest extent. One side surface of the pushing blade is fixedly connected to the outer surface of the rotating rod, and the pushing blade is positioned inside the compressed water hole. One side surface of the stirring blade is fixedly connected to the bottom outer surface of the rotating rod.

[0016] In one embodiment of the present invention, overlapping slots are provided on both sides of the cooling pool, and a foot pedal is detachably installed on the top surface of the cooling pool. The outer surface of the inclined plate is fixedly connected to the inner bottom wall of the cooling pool. Multiple inclined plates are provided. Water entering the cooling pool will directly impact the surface of the inclined plate. At the same time, in conjunction with the inclination angle of the inclined plate, the water will flow downward. When the water descends, it will carry iron oxide to the lowest point. As the water accumulates, it will flow upward along the other side of the inclined plate. When the water rises, it will gradually slide down using the gravity of the iron oxide itself and the downward force generated by the drop, thereby isolating most of the iron oxide.

[0017] In one embodiment of the present invention, the two side surfaces of the filter plate and the mixing mesh plate are movably sleeved on the inner wall of the overlapping groove, and a water pump is fixedly installed on the back of the cooling pool, and the output end of the water pump extends to the inner wall of the cooling pool.

[0018] In one embodiment of the present invention, a honeycomb mesh pipe is fixedly connected to the output end of the water pump, and the honeycomb mesh pipe is positioned between the filter plate and the mixing mesh plate. A water inlet is provided at the bottom left edge of the cooling pool, and a water outlet is provided at the top left edge of the cooling pool.

[0019] In one embodiment of the present invention, an inner cavity is provided on the inner wall of the water quenching tank, a water guide inclined pipe is fixedly connected to the inner wall of the inner cavity, and an arc-shaped funnel is provided on the inner bottom wall of the water quenching tank.

[0020] In one embodiment of the present invention, the other end of the return pipe is fixedly connected to the surface of the water quenching tank, and one end of the return pipe extends to the inner surface of the inner cavity. A baffle plate is fixedly connected to the inner wall of the inner cavity. With the inclination angle of the water guide pipe and the curvature of the inner wall of the water quenching tank, the water source injected into the water guide pipe will slide along the curvature of the inner wall of the water quenching tank, gradually causing the water source inside the water quenching tank to rotate. Using the vortex principle, the rotating water source will drive the iron oxide that has fallen off the surface of the steel to flow, gradually bringing the iron oxide closer to the middle of the water quenching tank.

[0021] The technical solution of the present invention has the following advantages compared with the prior art:

[0022] The annealing furnace water quenching device of this invention involves lifting red-hot steel into the water quenching tank. A return pipe re-injects filtered water from the cooling tank into the inner cavity of the tank. Simultaneously, a water guide pipe on the inner surface of the inner cavity guides the incoming water into the quenching tank. The angle of the guide pipe and the curvature of the inner wall of the quenching tank cause the water to slide along the curvature, gradually rotating. Utilizing the vortex principle, the rotating water carries away the detached iron oxide from the steel surface, gradually drawing it towards the center of the tank. The converging arc of the funnel then draws the collected iron oxide into the chip guide pipe. Combined with the filtration of the cooling tank, this effectively removes the detached iron oxide, preventing the settled iron oxide from adhering together.

[0023] The annealing furnace water quenching device described in this invention involves water entering the cooling pool and directly impacting the surface of an inclined plate. Simultaneously, the inclined plate's angle causes the water to flow downwards. As the water descends, it carries iron oxide to the lowest point. As the water accumulates, it flows upwards along the other side of the inclined plate. As the water rises, it gradually slides down due to the gravity of the iron oxide and the downward force generated by the drop, thus isolating most of the iron oxide. This achieves the effect of using gravity between iron oxides to settle and reduce the pressure on the filter screen.

[0024] The annealing furnace water quenching device of this invention filters fine iron oxide as it flows upward. The filtered water passes through the water holes on the surface of the filter plate and is guided upward. The impact of the water pushes the arc-shaped horn, causing the arc-shaped horn to drive the slide rod upward. Utilizing the change in the impact force of the water, the slide rod is pulled back by the elastic strip, causing the bottom end of the slide rod to strike the surface of the elastic filter. This knocks off some fine iron oxide adhering to the bottom surface of the elastic filter, reducing the amount of residual iron oxide on the surface of the elastic filter.

[0025] The annealing furnace water quenching device of this invention uses a water pump to inject low-temperature water into the cooling tank. The water is then atomized and discharged through a honeycomb mesh pipe, mixing with the heat-absorbing water. As the water passes through the mixing mesh plate, it pushes the internal pushing blades, causing the rotating rod to rotate on the inner surface of the clamping strip. This rotation of the stirring blades mixes the low-temperature and hot water, lowering the water temperature. When the water is reinjected into the water quenching tank, it mixes with the heat-absorbing water, and the rotating water further reduces the water temperature, maintaining a constant water temperature to the greatest extent possible.

[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0043] Reference Figure 1 As shown, an annealing furnace water quenching apparatus of the present invention includes:

[0044] Chip guide water pipe 12 is fixed to the bottom surface of the water quenching tank 11.

[0045] Cooling pool 13 is fixed to the surface of the other end of the chip guide water pipe 12.

[0046] The return pipe 14 is fixed to the top edge of the right side of the cooling pool 13.

[0047] A lower vibration cleaning unit is movably sleeved on the inner surface of the cooling pool 13. The lower vibration cleaning unit includes a filter plate 134 movably sleeved on the inner wall of the cooling pool 13. A water mixing unit is movably sleeved on the inner wall of the cooling pool 13 and located at the top edge of the filter plate 134. The water mixing unit includes a mixing mesh plate 137. An upper inclined settling unit is fixedly connected to the bottom inner wall of the cooling pool 13. The upper inclined settling unit includes an inclined plate 133.

[0048] like Figure 1 and Figure 5 As shown, a hydraulic compression driving unit is provided on the inner surface of the mixing mesh plate 137. The hydraulic compression driving unit includes a snap-fit ​​strip b1, a driving blade b3, and a stirring blade b4. An elastic pushing impact unit is movably sleeved on the inner surface of the filter plate 134. The elastic pushing impact unit includes an arc-shaped horn a4, an elastic strip a5, and an elastic filter screen a7. An inner liner cavity 111 is provided on the inner wall of the water quenching tank 11. A water guide inclined pipe 112 is fixedly connected to the inner wall of the inner liner cavity 111. At the same time, the water guide inclined pipe 112 on the inner surface of the inner liner cavity 111 guides the water source injected from 114 into the interior of the water quenching tank 11. An arc-shaped funnel 113 is provided on the inner bottom wall of the water quenching tank 11. Through the contraction arc of the arc-shaped funnel 113, the concentrated iron oxide is injected into the interior of the chip guide water pipe 12, and then combined with the lowering The warming pool 13 filters the water source, and the other end of the return pipe 14 is fixedly connected to the surface of the water quenching pool 11. When the red-hot steel is lifted into the water quenching pool 11, the water source filtered in the cooling pool 13 is re-injected into the inner cavity 111 in conjunction with the return pipe 14. One end of the return pipe 14 extends to the inner surface of the inner cavity 111. A baffle plate is fixedly connected to the inner wall of the inner cavity 111. With the inclination angle of the water guide pipe 112 and the curvature of the inner wall of the water quenching pool 11, the water source injected by the water guide pipe 112 will slide along the curvature of the inner wall of the water quenching pool 11, gradually causing the water source inside the water quenching pool 11 to rotate. Using the vortex principle, the rotating water source will drive the iron oxide that has fallen off the surface of the steel to flow, gradually bringing the iron oxide closer to the middle of the water quenching pool 11.

[0049] like Figure 2 - Figure 4As shown, overlapping slots 131 are provided on both sides of the cooling pool 13. A foot pedal 132 is detachably installed on the top surface of the cooling pool 13. The outer surface of the inclined plate 133 is fixedly connected to the inner bottom wall of the cooling pool 13. Multiple inclined plates 133 are provided. The water entering the cooling pool 13 will directly impact the surface of the inclined plate 133. At the same time, in conjunction with the inclination angle of the inclined plate 133, the water will flow downward. When the water descends, it will carry iron oxide to the lowest point. As the water accumulates, it will flow upward along the other side of the inclined plate 133. When the water rises, it will utilize the iron oxide... Due to its own gravity and the downward force generated by the drop, it gradually slides down, thereby isolating most of the iron oxide. The two sides of the filter plate 134 and the mixing mesh plate 137 are movably fitted onto the inner wall of the overlapping slot 131. A water pump 135 is fixedly installed on the back of the cooling pool 13, and the output end of the water pump 135 extends to the inner wall of the cooling pool 13. A honeycomb mesh tube 136 is fixedly connected to the output end of the water pump 135, and the honeycomb mesh tube 136 is positioned in the middle of the filter plate 134 and the mixing mesh plate 137. A water inlet is opened at the bottom left edge of the cooling pool 13, and a water outlet is opened at the top left edge of the cooling pool 13.

[0050] like Figure 6 As shown, a water passage hole a1 is formed on the outer surface of the filter plate 134. A snap-fit ​​strip a2 is fixedly connected to the upper and lower edges of the water passage hole a1. A limit ring is fixedly connected to one end of the snap-fit ​​strip a2. A slide rod a3 is movably fitted onto the inner surface of the limit ring. The top end of the slide rod a3 is fixedly connected to the bottom center of the arc-shaped horn a4. The impact of the water source will push the arc-shaped horn a4, causing the arc-shaped horn a4 to drive the slide rod a3 upwards. One end of the elastic strip a5 is fixedly connected to the bottom surface of the snap-fit ​​strip a2, and the other end of the elastic strip a5 is fixedly connected to the bottom outer surface of the slide rod a3. The change in the impact force of the water source, generated during the impact, is then controlled by the elastic strip a5. Pulling back the slide bar a3 causes its bottom end to strike the surface of the elastic filter screen a7, knocking off some fine iron oxide adhering to the bottom surface of the elastic filter screen a7, thus reducing the amount of residual iron oxide on the surface of the elastic filter screen a7. Limiting grooves a6 are provided on the bottom two sides of the filter plate 134. The two sides of the elastic filter screen a7 are movably fitted into the inner surface of the limiting grooves a6, and the bottom end of the slide bar a3 is movably overlapped with the top surface of the elastic filter screen a7. When some fine iron oxide flows upward, it is filtered by the elastic filter screen a7. The filtered water will flow upward through the water passage holes a1 on the surface of the filter plate 134.

[0051] like Figure 7As shown, the outer surface of the mixing mesh plate 137 has compressed water holes. Low-temperature water is pumped into the cooling tank 13 by the water pump 135, and the water is atomized and discharged through the honeycomb mesh pipe 136, mixing with the heat-absorbing water. As the water passes through the surface of the mixing mesh plate 137, it pushes the internal pushing blades b3. The outer surface of the second snap-fit ​​strip b1 is fixedly connected to the inner surface of the compressed water holes. A rotating rod b2 is movably sleeved on one end of the second snap-fit ​​strip b1, causing the rotating rod b2 to rotate on the inner surface of the second snap-fit ​​strip b1, thus driving the agitator... When the stirring blade b4 rotates, it stirs the low-temperature water source and the hot water source, mixing them together to lower the water source temperature. When the water source is re-injected into the water quenching tank 11, it will mix with the water source that has absorbed the heat, and then use the rotating water source to mix them together again, lowering the water source temperature and maintaining the water source temperature as much as possible. One side surface of the pushing blade b3 is fixedly connected to the outer surface of the rotating rod b2, and the position of the pushing blade b3 is set inside the compressed water hole. One side surface of the stirring blade b4 is fixedly connected to the bottom outer surface of the rotating rod b2.

[0052] The working principle of this auxiliary loading and unloading device will be explained in detail below.

[0053] When the red-hot steel is hoisted into the water quenching tank 11, the water filtered inside the cooling tank 13 is re-injected into the inner cavity 111 through the return pipe 14. At the same time, the water guide pipe 112 on the inner surface of the inner cavity 111 guides the water injected from 114 into the water quenching tank 11. With the inclination angle of the water guide pipe 112 and the curvature of the inner wall of the water quenching tank 11, the water injected through the water guide pipe 112 slides along the curvature of the inner wall of the water quenching tank 11, gradually causing the water inside the water quenching tank 11 to rotate. Using the vortex principle, the rotating water will drive the iron oxide that has fallen off the surface of the steel to flow, gradually bringing the iron oxide closer to the center of the water quenching tank 11. Then, through the contraction curvature of the arc funnel 113, the concentrated iron oxide is injected into the chip guide water pipe 12, and then the water is filtered by the cooling tank 13.

[0054] The water entering the cooling pool 13 will directly impact the surface of the inclined plate 133. At the same time, the inclined plate 133 will cause the water to flow downward. When the water descends, it will carry the iron oxide to the lowest point. As the water accumulates, it will flow upward along the other side of the inclined plate 133. When the water rises, it will gradually slide down using the gravity of the iron oxide itself and the downward force generated by the drop, thereby isolating most of the iron oxide.

[0055] When fine iron oxide flows upward, it is filtered by the elastic filter screen a7. The filtered water flows upward through the water passage holes a1 on the surface of the filter plate 134. The impact of the water pushes the arc-shaped horn a4, causing the arc-shaped horn a4 to drive the slide rod a3 to slide upward. Utilizing the change in the impact force of the water, the elastic strip a5 pulls the slide rod a3 back, causing the bottom of the slide rod a3 to hit the surface of the elastic filter screen a7. This knocks off some fine iron oxide adhering to the bottom surface of the elastic filter screen a7, reducing the amount of iron oxide remaining on the surface of the elastic filter screen a7.

[0056] Low-temperature water is pumped into the cooling tank 13 by water pump 135, and the water is atomized and discharged by honeycomb mesh pipe 136, so that it mixes with the water that has absorbed heat. When the water passes through the surface of the mixing mesh plate 137, it pushes the internal pushing blade b3, thereby driving the rotating rod b2 to rotate on the inner surface of the clamping strip b1. When the stirring blade b4 rotates, it stirs the low-temperature water and hot water together, thereby reducing the temperature of the water. When the water is pumped back into the water quenching tank 11, it will mix with the water that has absorbed heat, and then the rotating water will mix them together again, reducing the temperature of the water and maintaining the constant temperature of the water to the greatest extent.

[0057] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
