Description

Technical Field

[0001] The invention belongs to the technical field of equipment cooling, in particular to a circulating cooling device for a forging machine of an oil drilling rig. Background Art

[0002] A circulating cooling device for a forging press on an oil drilling rig is a system designed specifically for controlling the temperature of the hydraulic oil in the forging press. It achieves efficient circulating cooling of the hydraulic oil by integrating a dual cooling mechanism of water cooling and air cooling.

[0003] In the existing technology, a pressure pump drives high-temperature hydraulic oil from the hydraulic system of the forging press to flow into the oil tank of the cooling device. The oil flows through the built-in spiral coil or heat dissipation fins in the oil tank and performs forced heat exchange with the cooling water (or refrigerant) circulating in the coil. After the heat is absorbed by the cooling medium, the low-temperature hydraulic oil returns to the hydraulic system to continue working. At the same time, the cooling medium that absorbs the heat is transported to the external radiator or air-cooled module through a water pump, and re-enters the cooling cycle after being accelerated by the fan to dissipate heat, forming a closed-loop control system to ensure that the hydraulic oil temperature is stable within a safe working range, avoiding oil degradation, seal failure and equipment failure caused by overheating.

[0004] There are still some problems in the actual application of the above scheme. Although the existing device can complete the cooling function of the hydraulic oil in the forging machine, the cooling medium after cooling will re-enter the water tank through the return pipe, which will increase the water temperature in the water tank, and the hot water with reduced density will rise, and the cold water will sink, forming natural convection, which will make the convection intensity insufficient, resulting in the inability to evenly diffuse heat, and making the water temperature in different areas of the water tank vary greatly. As the cooling process continues, the temperature of the cooling medium extracted from different positions of the water tank fluctuates greatly, and it is impossible to provide stable and uniform cooling for the hydraulic oil. This will cause the temperature of each part of the hydraulic oil to be inconsistent during the cooling process, and the overall cooling effect will deteriorate, so that the temperature of the hydraulic oil cannot be effectively controlled within the ideal range.

[0005] To this end, the present invention provides a circulating cooling device for a forging machine of an oil drilling rig. Summary of the Invention

[0013] Preferably, the blocking block slides inside the limit groove, and the blocking block is used to prevent the sliding plate from excessively descending and stretching. The horizontal plate of the water blocking plate is used to block the flow of water, and its vertical plate is used to protect the fixed block, the swing rod and the first rotating rod when the stirring plate rotates.

[0014] Preferably, a mobile collecting mechanism for collecting impurities is provided inside the rotating stirring mechanism, and the mobile collecting mechanism includes a collecting frame, which is slidably connected to the inside of the first rotating shaft, a pull ring is fixedly connected to the middle of one end of the collecting frame, and a second gear is fixedly connected to the inner ring surface of the end of the first rotating shaft away from the rotating motor; A first gear is rotatably connected inside the collection frame.

[0017] The beneficial effects of the present invention are as follows: 1. The circulating cooling device of a forging press of oil drilling equipment described in the present invention has multiple groups of stirring plates arranged in a ring around the central axis of the first rotating shaft. Therefore, when the first rotating shaft rotates, the cooling medium inside the hydraulic oil tank can be stirred. Since multiple filter holes are opened through the surface of the stirring plate, when the stirring plate rotates, the filter holes will be driven to rotate synchronously. The setting of the stirring plate can break the temperature stratification inside the water body, making the water temperature more uniform, and at the same time promote the movement of water molecules, enhance the convection heat exchange effect between water and the inner wall of the pipeline, and at the same time, the setting of the filter holes can further enhance the fluidity of the water body inside the circulating water tank, thereby further improving the uniformity of the temperature of the cooling medium inside the circulating water tank.

[0018] 2. The circulating cooling device of a forging machine of an oil drilling rig equipment described in the present invention has a swing arm that rotates on the side of the fixed block, and the swing arm is rotatably connected to the first rotating arm. Therefore, when the first rotating arm moves downward, it will be limited by the swing arm to cause the first rotating arm to rotate around the rotating shaft between it and the top of the sliding plate, thereby causing the transverse plates of the two water blocking plates to change from a flat state to a "V"-shaped state. Since a certain gap is left between the transverse plates of the water blocking plates and the side surfaces of the sliding plates, the liquid medium remaining through the flat drain outlet will flow along the gap to the surface of the stirring plate, thereby improving the device under different flow rate conditions. The cooling medium can always flow to the surface of the stirring plate. The arrangement of the stirring plate and the flat drain outlet can keep the surface of the stirring plate clean at all times, ensuring the uniformity of the temperature of the cooling medium in the circulating water tank. At the same time, the arrangement of the water blocking plate can enable the device to adapt to the situation where the cooling medium can flow to the surface of the stirring plate under different flow rates, thereby improving the applicability of the device.

[0019] 3. The circulating cooling device of a forging press of an oil drilling rig equipment described in the present invention, at the same time, since the second rotating rod is fixedly connected to the first gear, when the first gear rotates, it will synchronously drive the second rotating rod to rotate, and then drive the pushing blade fixed on the outer ring surface of the second rotating rod to rotate. Since the outer edge of the pushing blade is in contact with the inner ring surface of the collecting frame trough, the impurities collected in the collecting frame trough can be pushed to one side when the second rotating rod rotates, thereby ensuring the fluidity of the cavity at the bottom of the collecting frame trough, reducing the inability to discharge the collecting frame trough due to the inflow of cooling medium, and avoiding the situation where the water level in the collecting frame trough suddenly rises due to the rapid inflow of cooling medium, causing impurities to flow back into the circulating water tank, thereby reducing the content of cooling medium impurities in the circulating water tank, and further improving the cooling rate of the hydraulic oil by the device.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0023] like Figures 1 to 8 As shown, a circulating cooling device for a forging press of a petroleum drilling rig according to an embodiment of the present invention includes a forging press cooling device 1, wherein the forging press cooling device 1 includes a hydraulic oil tank 101, a circulating water tank 102 fixedly connected to the top of the hydraulic oil tank 101, a cooling water pipe 103 fixedly connected to the bottom of the circulating water tank 102, a fan 104 fixedly connected to the top of the circulating water tank 102, and a rotating stirring mechanism 2 provided inside the forging press cooling device 1; The rotating stirring mechanism 2 includes a stirring plate 204 rotatably disposed inside the circulating water tank 102 . The water in the circulating water tank 102 can be stirred by the rotation of the stirring plate 204 .

[0024] Specifically, although the existing device can complete the cooling function of the hydraulic oil in the forging machine, the cooling medium will re-enter the water tank through the return pipe after cooling, which will increase the water temperature in the water tank. The hot water with reduced density will rise and the cold water will sink, forming natural convection, which will make the convection intensity insufficient, resulting in uneven heat diffusion, and causing large differences in water temperature in different areas of the water tank. As the cooling process continues, the temperature of the cooling medium extracted from different positions of the water tank fluctuates greatly, and it is impossible to provide stable and uniform cooling for the hydraulic oil. This will cause inconsistent temperatures in different parts of the hydraulic oil during the cooling process, poor overall cooling effect, and thus the hydraulic oil temperature cannot be effectively controlled within the ideal range. Therefore, the present invention solves this problem by setting a corresponding structure. The circulating cooling device of the forging press of the oil drilling equipment described in the present invention, when the forging press is working, the temperature of the hydraulic oil in the hydraulic oil tank 101 will increase, and the water pump set in the circulating water tank 102 will be started at this time. When the water pump is started, the cooling medium in the circulating water tank 102 will flow into the hydraulic oil tank 101 through the water inlet of the cooling water pipe 103, and cool the hydraulic oil in the hydraulic oil tank 101 during the flow of the cooling medium in the pipeline. When the cooling medium in the cooling water pipe 103 completes the cooling work, the cooling medium that has completed the cooling work will be discharged back to the inside of the circulating water tank 102 through the water outlet of the cooling water pipe 103, and the fan 104 is started to cool the cooling medium. However, since the cooling medium after cooling will re-enter the water tank through the return water pipe, this will increase the water temperature in the water tank, and the density The lowered hot water will rise and the cold water will sink, forming natural convection, which will make the convection intensity insufficient, resulting in the inability to diffuse heat evenly, and causing large differences in water temperature in different areas of the water tank. As the cooling process continues, the temperature of the cooling medium extracted from different positions of the water tank fluctuates greatly, and it is impossible to provide stable and uniform cooling for the hydraulic oil. This will cause the temperatures of various parts of the hydraulic oil to be inconsistent during the cooling process, and the overall cooling effect will deteriorate, so that the temperature of the hydraulic oil cannot be effectively controlled within the ideal range. At this time, the stirring plate 204 in the rotating stirring mechanism 2 will rotate, and stir the cooling medium inside the circulating water tank 102 during the rotation, thereby breaking the temperature stratification inside the water body and making the water temperature more uniform. At the same time, it promotes the movement of water molecules and enhances the convective heat exchange effect between water and the inner wall of the pipe. When the stirred water flows into the hydraulic oil cooling system, it can more efficiently absorb the heat in the hydraulic oil and speed up the cooling speed. Example

[0025] like Figures 2 to 8 As shown in Comparative Example 1, another embodiment of the present invention is: like Figure 2 and Figure 3 As shown, the rotating stirring mechanism 2 of this embodiment includes a rotating motor 201, and the rotating motor 201 is fixedly connected to the side wall of the circulating water tank 102; The output end of the rotating motor 201 is fixedly connected to a first rotating shaft 202, and the first rotating shaft 202 is a hollow cylindrical tube; A water inlet groove 203 is formed on the outer ring surface of the first rotating shaft 202, a stirring plate 204 is fixedly connected to the outer ring surface of the first rotating shaft 202, a filtering hole 205 is formed on the side wall of the stirring plate 204, and a flat drain port 206 is fixedly connected to the outlet of the cooling water pipe 103.

[0026] Specifically, when the cooling medium in the circulating water tank 102 flows into the hydraulic oil tank 101, the rotating motor 201 fixed to the side wall of the circulating water tank 102 is started. At this time, the rotating motor 201 drives the first rotating shaft 202 fixed thereto to rotate synchronously through its output shaft, and at the same time, it drives the stirring plate 204 fixedly connected to its outer ring surface to rotate synchronously. Since the stirring plates 204 are arranged in a ring around the central axis of the first rotating shaft 202 in multiple groups, the cooling medium inside the hydraulic oil tank 101 can be cooled when the first rotating shaft 202 rotates. The stirring plate 204 is provided with a plurality of filter holes 205 on its surface, so when the stirring plate 204 rotates, the filter holes 205 are synchronously driven to rotate. The setting of the stirring plate 204 can break the temperature stratification inside the water body, make the water temperature more uniform, and promote the movement of water molecules, enhance the convection heat exchange effect between water and the inner wall of the pipe, and at the same time, the setting of the filter holes 205 can further enhance the fluidity of the water body inside the circulating water tank 102, thereby further improving the uniformity of the temperature of the cooling medium inside the circulating water tank 102.

[0027] like Figure 4 and Figure 5 As shown, the stirring plate 204 in this embodiment is provided with a groove at the top, and a return spring 207 is fixedly connected to the bottom of the groove of the stirring plate 204. One end of the return spring 207 is fixedly connected to a sliding plate 208. The sliding plate 208 slides in the groove at the top of the stirring plate 204. A limiting groove 209 is provided on the side wall of the sliding plate 208. A blocking block 210 is fixedly connected to the groove at the top of the stirring plate 204.

[0028] like Figure 5 As shown, in this embodiment, the top of the stirring plate 204 is fixedly connected to a fixed block 211, and the side wall of the fixed block 211 is rotatably connected to a swing rod 212, and the other end of the swing rod 212 is rotatably connected to a first rotating rod 213, and the first rotating rod 213 is rotatably connected to the top of the sliding plate 208; A water blocking plate 214 is fixedly connected to the side wall of the first rotating rod 213 . The water blocking plate 214 is composed of a vertical plate and a horizontal plate.

[0029] Specifically, when the stirring plate 204 rotates, it will synchronously drive the sliding plate 208 to rotate synchronously. When the stirring plate 204 and the sliding plate 208 move above the water surface and are in a vertical state, they will be on the same vertical plane as the flat drain outlet 206. At this time, when the cooling water flows into the flat drain outlet 206 through the cooling water pipe 103, the cooling medium will flow out in a flat shape due to the restriction of the flat drain outlet 206. Since the stirring plate 204 and the flat drain outlet 206 are on the same vertical plane at this time, the outflowing cooling medium will move downward along the surface of the stirring plate 204, thereby washing away impurities on the surface of the stirring plate 204, thereby preventing impurities from accumulating for a long time and blocking the filter hole 205 when the stirring plate 204 rotates. At the same time, the setting of the filter hole 205 can also collect impurities in the water in the circulating water tank 102 during movement. When the water flow discharged from the cooling water pipe 103 becomes larger, the sliding plate 208 in contact with it will be squeezed downward due to gravity. At this time, the sliding plate 208 will move downward along the guide of the groove on the top of the stirring plate 204, and at the same time drive the first rotating rod 213 connected to its top to move synchronously. However, since the fixed block 211 is fixed to the top of the stirring plate 204, the fixed block 211 will not move downward when the first rotating rod 213 moves downward. Since the swing rod 212 is rotated on the side of the fixed block 211, and the swing rod 212 is rotatably connected to the first rotating rod 213, when the first rotating rod 213 moves downward, it will be limited by the swing rod 212 so that the first rotating rod 213 moves around the top of the sliding plate 208. The rotating shaft rotates, thereby causing the transverse plates of the two water blocking plates 214 to change from a flat state to a "V"-shaped state. Since a certain gap is left between the transverse plates of the water blocking plates 214 and the sides of the sliding plates 208, the liquid medium left through the flat drain port 206 will flow along the gap to the surface of the stirring plate 204, thereby improving the device under different flow rate conditions. The cooling medium can always flow to the surface of the stirring plate 204. The arrangement of the stirring plate 204 and the flat drain port 206 can keep the surface of the stirring plate 204 clean at all times, ensuring the uniformity of the temperature of the cooling medium inside the circulating water tank 102. At the same time, the arrangement of the water blocking plates 214 can enable the device to adapt to the situation where the cooling medium can flow to the surface of the stirring plate 204 under different flow rates, thereby improving the applicability of the device.

[0030] like Figure 7 and Figure 8As shown, the rotating stirring mechanism 2 of this embodiment is internally provided with a mobile collecting mechanism 3 for collecting impurities. The mobile collecting mechanism 3 includes a collecting frame 301, which is slidably connected to the inside of the first rotating shaft 202. A pull ring 302 is fixedly connected to the middle of one end of the collecting frame 301. A second gear 304 is fixedly connected to the inner ring surface of the end of the first rotating shaft 202 away from the rotating motor 201. The collecting frame 301 is internally connected to a first gear 303 which is rotatable. The collecting frame 301 is composed of a water collecting trough and a fixed column. The first gear 303 rotates on the fixed column portion of the collecting frame 301 .

[0031] like Figure 7 and Figure 8 As shown, in this embodiment, the middle part of the first gear 303 is rotatably connected to the second rotating rod 305, the outer ring surface of the second rotating rod 305 is fixedly connected to the push blade 306, and the outer ring surface of the circulating water tank 102 is rotatably connected to the clamping plate 307. When the collection frame 301 is installed, the side of the collection frame 301 away from the motor will be against the clamping plate 307.

[0032] Specifically, when the stirring plate 204 and the flat drain port 206 are on the same vertical plane, the water inlet groove 203 formed through the outer annular surface of the first rotating shaft 202 will be on the same vertical plane as the "V-shaped" opening formed on the water collection tank of the collection frame 301. At this time, the cooling medium flowing down through the stirring plate 204 will carry impurities on the surface of the stirring plate 204 and flow into the water collection tank of the collection frame 301. Since the bottom of the water collection tank is provided with a plurality of holes, when the cooling medium flows into the water collection tank, the impurities will be retained in the water collection tank of the collection frame 301, and the cooling medium will flow back into the circulating water tank 102. However, since the rotating motor 201 always drives the first rotating shaft 202 to rotate slowly, it will drive the first rotating shaft 202 to rotate away from the second gear 304 set on the inner ring surface of one end of the rotating motor 201 to rotate synchronously. At the same time, since the second gear 304 is meshed with the first gear 303, and the first gear 303 is rotating in the collection frame 301, when the first rotating shaft 202 rotates, it will synchronously drive the first gear 303 to rotate. At the same time, since the second rotating rod 305 is fixedly connected to the first gear 303, when the first gear 303 rotates, it will synchronously drive the second rotating rod 305 to rotate, and then drive the second rotating rod 305 fixed to the second rotating rod 305 to rotate. The push blade 306 on the outer annular surface rotates. Since the outer edge of the push blade 306 is in contact with the inner annular surface of the water collecting tank of the collection frame 301, the impurities collected in the water collecting tank of the collection frame 301 can be pushed to one side when the second rotating rod 305 rotates, thereby ensuring the fluidity of the cavity at the bottom of the water collecting tank of the collection frame 301, reducing the inability of the cooling medium to be discharged from the water collecting tank of the collection frame 301 due to the inflow, and avoiding the situation where the water level in the water collecting tank of the collection frame 301 suddenly rises due to the rapid inflow of the cooling medium, causing impurities to flow back into the circulating water tank 102, thereby reducing the content of cooling medium impurities in the circulating water tank 102, and further improving the cooling rate of the hydraulic oil by the device.

[0033] Working principle: when the cooling medium in the circulating water tank 102 flows into the hydraulic oil tank 101, the rotating motor 201 fixed to the side wall of the circulating water tank 102 is started. At this time, the rotating motor 201 will drive the first rotating shaft 202 fixed to it to rotate synchronously through its output shaft, and at the same time, it will synchronously drive the stirring plate 204 fixed to its outer ring surface to rotate synchronously. Since the stirring plates 204 are arranged in multiple groups around the central axis of the first rotating shaft 202, the cooling medium inside the hydraulic oil tank 101 can be cooled when the first rotating shaft 202 rotates. The medium is stirred. Since a plurality of filter holes 205 are provided on the surface of the stirring plate 204, the filter holes 205 are driven to rotate synchronously when the stirring plate 204 rotates. The setting of the stirring plate 204 can break the temperature stratification inside the water body, make the water temperature more uniform, and promote the movement of water molecules, enhance the convection heat exchange effect between water and the inner wall of the pipe, and at the same time, the setting of the filter holes 205 can further enhance the fluidity of the water body inside the circulating water tank 102, thereby further improving the uniformity of the temperature of the cooling medium inside the circulating water tank 102.

[0034] When the stirring plate 204 rotates, it will synchronously drive the sliding plate 208 to rotate synchronously. When the stirring plate 204 and the sliding plate 208 move above the water surface and are in a vertical state, they will be on the same vertical plane as the flat drain outlet 206. At this time, when the cooling water flows into the flat drain outlet 206 through the cooling water pipe 103, the cooling medium will flow out in a flat shape due to the restriction of the flat drain outlet 206. Since the stirring plate 204 and the flat drain outlet 206 are on the same vertical plane at this time, the outflowing cooling medium will move downward along the surface of the stirring plate 204, thereby washing away impurities on the surface of the stirring plate 204, thereby preventing impurities from accumulating for a long time and blocking the filter hole 205 when the stirring plate 204 rotates. At the same time, the setting of the filter hole 205 can also collect impurities in the water in the circulating water tank 102 during movement. When the water flow discharged from the cooling water pipe 103 becomes larger, the sliding plate 208 in contact with it will be squeezed downward due to gravity. At this time, the sliding plate 208 will move downward along the guide of the groove on the top of the stirring plate 204, and at the same time drive the first rotating rod 213 connected to its top to move synchronously. However, since the fixed block 211 is fixed to the top of the stirring plate 204, the fixed block 211 will not move downward when the first rotating rod 213 moves downward. Since the swing rod 212 is rotated on the side of the fixed block 211, and the swing rod 212 is rotatably connected to the first rotating rod 213, when the first rotating rod 213 moves downward, it will be limited by the swing rod 212 so that the first rotating rod 213 moves around the top of the sliding plate 208. The rotating shaft rotates, thereby causing the transverse plates of the two water blocking plates 214 to change from a flat state to a "V"-shaped state. Since a certain gap is left between the transverse plates of the water blocking plates 214 and the sides of the sliding plates 208, the liquid medium left through the flat drain port 206 will flow along the gap to the surface of the stirring plate 204, thereby improving the device under different flow rate conditions. The cooling medium can always flow to the surface of the stirring plate 204. The arrangement of the stirring plate 204 and the flat drain port 206 can keep the surface of the stirring plate 204 clean at all times, ensuring the uniformity of the temperature of the cooling medium inside the circulating water tank 102. At the same time, the arrangement of the water blocking plates 214 can enable the device to adapt to the situation where the cooling medium can flow to the surface of the stirring plate 204 under different flow rates, thereby improving the applicability of the device.

[0035] When the stirring plate 204 and the flat drain port 206 are on the same vertical plane, the water inlet groove 203 formed through the outer annular surface of the first rotating shaft 202 will be on the same vertical plane as the "V-shaped" opening formed on the water collection tank of the collection frame 301. At this time, the cooling medium flowing down through the stirring plate 204 will carry impurities on the surface of the stirring plate 204 and flow into the water collection tank of the collection frame 301. Since the bottom of the water collection tank is provided with a plurality of holes, when the cooling medium flows into the water collection tank, the impurities will be retained in the water collection tank of the collection frame 301, and the cooling medium will flow back into the circulating water tank 102. However, since the rotating motor 201 always drives the first rotating shaft 202 to rotate slowly, it will drive the first rotating shaft 202 to rotate away from the second gear 304 set on the inner ring surface of one end of the rotating motor 201 to rotate synchronously. At the same time, since the second gear 304 is meshed with the first gear 303, and the first gear 303 is rotating in the collection frame 301, when the first rotating shaft 202 rotates, it will synchronously drive the first gear 303 to rotate. At the same time, since the second rotating rod 305 is fixedly connected to the first gear 303, when the first gear 303 rotates, it will synchronously drive the second rotating rod 305 to rotate, and then drive the second rotating rod 305 fixed to the second rotating rod 305 to rotate. The push blade 306 on the outer annular surface rotates. Since the outer edge of the push blade 306 is in contact with the inner annular surface of the water collecting tank of the collection frame 301, the impurities collected in the water collecting tank of the collection frame 301 can be pushed to one side when the second rotating rod 305 rotates, thereby ensuring the fluidity of the cavity at the bottom of the water collecting tank of the collection frame 301, reducing the inability of the cooling medium to be discharged from the water collecting tank of the collection frame 301 due to the inflow, and avoiding the situation where the water level in the water collecting tank of the collection frame 301 suddenly rises due to the rapid inflow of the cooling medium, causing impurities to flow back into the circulating water tank 102, thereby reducing the content of cooling medium impurities in the circulating water tank 102, and further improving the cooling rate of the hydraulic oil by the device.
