Description

Technical Field

[0001] The invention relates to the technical field of centrifugal production of cast steel shots, in particular to a centrifuge used for producing cast steel shots. Background Art

[0002] Cast steel shot is made of high-quality steel scraps, which are first melted and then ejected through a centrifuge to form molten steel droplets that fall into a cooling water pool to form small spherical steel shots. The formed shot is heated again to purify and homogenize, and then quenched. Cast steel shot is widely used for descaling and rust removal of steel workpieces before painting. Centrifugal shot blasting equipment is often used in this case. The spherical shape and lower hardness will prevent the steel shot from causing greater wear on the equipment. At the same time, steel shot is also widely used in the foundry industry. When the workpiece is taken out of the mold, the steel shot is used to remove the sand on the surface of the workpiece.

[0003] After searching, the Chinese invention patent with announcement number CN106735277A discloses a centrifuge for producing cast steel shots, which includes a motor, a rotating shaft, a transmission shaft and a centrifugal brick. The main feature is that it also includes a lifting part and a support platform above the cast steel shot pool, the motor is installed on the support platform, the rotating shaft is connected to the output end of the motor, and the bottom end of the rotating shaft is fixedly connected to a gear cylinder; the outer wall of the gear cylinder is provided with transmission teeth, the bottom of the gear cylinder is provided with a conical gear table, and the bottom end of the gear cylinder is slidably installed with a transmission shaft; the top of the transmission shaft is provided with conical teeth meshing with the conical gear table, and the bottom end of the transmission shaft is fixedly connected to a brick shell.

[0004] Based on the existing technology, it is found that the above patent still has the following shortcomings: when the molten steel is ejected through the centrifugal hole on the outer wall of the brick shell, it is in a continuous ejection state. This ejection method easily leads to the ejection of the molten steel at a too fast flow rate, resulting in two or more steel shots sticking together to form a conjoined irregular shape. At the same time, continuous ejection will also cause a certain degree of cooling of the cooling effect of the cooling pool, making the quality of the formed steel shots relatively poor. Therefore, a centrifuge for producing cast steel shots is urgently needed to solve the above problems. Summary of the invention

[0016] Beneficial effects of the present invention: The present invention provides a centrifuge for producing cast steel shots. The centrifuge can drive a baffle located inside a centrifugal brick cylinder to make intermittent circular motion when the centrifuge is started, thereby realizing intermittent blocking of some centrifugal holes, so that the spraying mode of the centrifuge is changed from continuous spraying to intermittent spraying, effectively avoiding the situation that a large number of steel shots are connected and shaped due to the continuous spraying speed being too fast, thereby improving the quality of the output steel shots, and at the same time, it also has a cooling effect on the cooling water inside the water pool, thereby avoiding the situation that the continuous spraying of molten steel causes the cooling water inside the water pool to heat up too fast locally. Specifically, by providing a power component and a blocking component, when the staff needs to produce cast steel shots, they can first start the motor and pour the molten steel into the centrifugal brick cylinder from the pouring port at the same time. The starting of the motor can drive the rotating rod and two sets of driving gears to rotate, and when the two sets of driving gears rotate, they can drive The gear ring meshing with it rotates together, and the rotation of the gear ring can drive the entire centrifugal brick cylinder to rotate together to perform centrifugal injection. When the centrifugal brick cylinder rotates, the support frame fixed on the top of it will also rotate accordingly. The rotation of the support frame can drive the ring gear plate to rotate, and the ring gear plate meshes with the fifth gear, thereby driving the fifth gear and the rotating rod to rotate. During the rotation of the rotating rod, the fourth gear at the bottom can be driven to rotate. Since the tooth groove portion on the outer wall of the fourth gear has only three groups, intermittent meshing with the second gear can be achieved, thereby ensuring that the second gear rotates intermittently, and through the rotation of the second gear and the mutual meshing transmission between the third gear and the first gear, the ring frame and the baffle can be driven to do intermittent circular motion, which can achieve intermittent blocking of some centrifugal holes and meet people's needs for intermittent injection of molten steel.

[0017] The invention provides a centrifuge for producing cast steel shots. Through the provided equalizing plate and equalizing holes, workers will first contact the equalizing plate when pouring molten steel. The equalizing holes on the equalizing plate can reduce the impact force generated when the molten steel is poured, and a good splash-proof effect is achieved. Meanwhile, the equalizing plate is horizontally arranged inside a centrifugal brick cylinder, so that the molten steel can be evenly dropped into the centrifugal brick cylinder, and a large amount of molten steel is avoided from falling into a certain area of ​​the centrifugal brick cylinder at the same time, resulting in uneven force on the centrifugal brick cylinder during the centrifugal process, leading to a large difference in the size of the molten steel droplets thrown out, and a certain effect of balancing the centrifugal rotation stress is achieved, and the quality of the output steel shot is guaranteed. Moreover, the cross sections of the equalizing holes on the equalizing plate are all oblique, so that a certain centrifugal force can be generated during the rotation of the centrifugal brick cylinder, accelerating the droplets to separate from the equalizing holes and fall into the inside of the centrifugal brick cylinder, and avoiding a large number of blockages in the equalizing holes.

[0018] The present invention provides a centrifuge for producing cast steel shots. Through the provided cooling component, the external water pipe is connected to the liquid inlet hole at the top of the first cooling sleeve before the centrifuge is started, so that the first cooling sleeve and the second cooling sleeve can be continuously replenished with liquid. At the same time, as a large amount of cold water is introduced into the first cooling sleeve and the second cooling sleeve, continuous heat exchange can be performed with the rotating rod at the output end of the motor, thereby reducing the operating temperature of the rotating rod and the motor, and effectively extending the service life of the motor and the rotating rod. The spiral blades provided inside the first cooling sleeve can make the cold water flow in a spiral shape, which not only extends the heat exchange time with the rotating rod, but also allows the cold water to fully exchange with the rotating rod. The heat exchange is divided, which improves the cooling effect of the first cooling sleeve on the rotating rod. Finally, the cold water after heat exchange will be thrown out through the nozzle, and the thrown water droplets will contact with some molten steel droplets, so as to pre-cool the molten steel droplets and accelerate the cooling and forming speed of the molten steel droplets. In the process of throwing out the cold water, the fan blades below will also rotate together, which can not only diffuse the cold water droplets, so that the cold water droplets cover a wider area and contact with more molten steel droplets, but also blow the high-temperature water mist generated by the cooling of the molten steel droplets in the water pool downward, avoiding the situation that a large amount of high-temperature water mist rises and contacts with the cooling components, rotating rods and motors, resulting in a decrease in heat exchange effect and a shortened service life.

The blocking component includes a ring frame 25 arranged inside the centrifugal brick cylinder 5, and the bottom outer wall of the ring frame 25 is fixedly connected with baffles 26 distributed in a circular shape at equal distances. The number of baffles 26 is half the number of centrifugal holes 9. The circumferential outer wall of the baffle 26 is close to the circumferential inner wall of the centrifugal brick cylinder 5. When the centrifuge is started, the baffle 26 located inside the centrifugal brick cylinder 5 can be driven to make intermittent circular motion, thereby achieving intermittent blocking of some centrifugal holes 9, so that the injection mode of the centrifuge is changed from continuous injection to intermittent injection, which effectively avoids the situation that a large number of steel shots are conjoined and shaped due to the continuous injection speed being too fast, improves the quality of the output steel shots, and also cools the cooling water inside the water pool 1, avoiding the situation that the cooling water inside the water pool 1 is locally heated too fast due to the continuous injection of molten steel; A power assembly for driving the blocking assembly to rotate is arranged inside the centrifugal brick cylinder 5; The pouring port 3 is opened at the top of the horizontal plate 2 , and the pouring port 3 is located directly above the centrifugal brick cylinder 5 .

[0033] Preferably, the power assembly includes a support frame 11 fixedly connected to the top outer wall of the centrifugal brick cylinder 5, the top outer wall of the support frame 11 is fixedly connected to the first rotating column 8, the first rotating column 8 is rotatably connected to the horizontal plate 2, the bottom outer wall of the support frame 11 is respectively fixedly connected to the rotating seat and the vertical column 31, the rotating seat is rotatably connected to the rotating rod 18, the bottom end of the vertical column 31 is fixedly connected to the ring gear plate 32, the circumferential inner wall of the ring gear plate 32 is meshed with the fifth gear 33, the fifth gear 33 is fixedly connected to the circumferential outer wall of the rotating rod 18, and the end of the rotating rod 18 away from the rotating seat is fixedly connected to The fourth gear 30 includes a tooth groove portion 3001 and a ring plate portion 3002. The fourth gear 30 is meshed with the second gear 28 through the tooth groove portion 3001. The circumferential inner wall of the second gear 28 is fixedly connected with the second rotating column 27. The bottom end of the second rotating column 27 is rotatably connected to the bottom inner wall of the centrifugal brick cylinder 5. The top outer wall of the second rotating column 27 is fixedly connected with the third gear 29. The circumferential outer wall of the third gear 29 is meshed with the first gear 23. The top outer wall of the first gear 23 is fixedly connected with the reinforcing frame 24. The other end of the reinforcing frame 24 is fixedly connected to the ring frame 25. The motor 4 is started to drive the rotating rod 35 and the two sets of driving gears 13 to rotate. When the two sets of driving gears 13 rotate, the gear ring 10 meshing therewith can be driven to rotate together. The rotation of the gear ring 10 can drive the entire centrifugal brick cylinder 5 to rotate together to perform centrifugal injection. When the centrifugal brick cylinder 5 rotates, the support frame 11 fixed on the top thereof will also rotate together. The rotation of the support frame 11 can drive the ring gear plate 32 to rotate, and the ring gear plate 32 meshes with the fifth gear 33, thereby driving the fifth gear 33 and the rotating rod 18 to rotate. During the rotation of the rotating rod 18, the fourth gear 30 at the bottom thereof can be driven to rotate. Since the tooth groove portion 3001 on the outer wall of the fourth gear 30 has only three groups, intermittent meshing with the second gear 28 can be achieved, thereby ensuring that the second gear 28 rotates intermittently. Through the rotation of the second gear 28 and the mutual meshing transmission between the third gear 29 and the first gear 23, the ring frame 25 and the baffle 26 can be driven to perform intermittent circular motion, thereby achieving intermittent blocking of some centrifugal holes 9, thereby meeting people's demand for intermittent injection of molten steel.

[0034] Preferably, the equalizing component includes an equalizing plate 17 fixedly connected to the inner wall of the circumference of the centrifugal brick cylinder 5, and the top outer wall of the equalizing plate 17 is provided with equalizing holes 21 distributed in a circular shape at equal distances, and a circular groove 19 is provided in the middle of the equalizing plate 17. One end of the rotating rod 18 passes through the inside of the circular groove 19. The cross section of the equalizing hole 21 is oblique, and the angle between the equalizing hole 21 and the horizontal plane is 40°-60°. When the staff pours the molten steel, they will first contact the equalizing plate 17. The equalizing holes 21 on the equalizing plate 17 can reduce the impact force generated when the molten steel is poured, and a good splash-proof effect is achieved. At the same time, the equalizing plate 17 is horizontally arranged on the centrifugal The inside of the brick cylinder 5 can make the molten cast steel fall evenly into the inside of the centrifugal brick cylinder 5, avoiding a large amount of molten steel from falling into a certain area of ​​the centrifugal brick cylinder 5 at the same time, causing the centrifugal brick cylinder 5 to be subjected to uneven force during the centrifugal process, resulting in a large difference in the size of the molten steel droplets thrown out, which has a certain effect of balancing the centrifugal rotation stress and ensuring the quality of the output steel shots. The cross-sections of the equalizing holes 21 opened on the equalizing plate 17 are all oblique, so that a certain centrifugal force can be generated during the rotation of the centrifugal brick cylinder 5, accelerating the droplets to detach from the equalizing holes 21 and fall into the inside of the centrifugal brick cylinder 5, avoiding the occurrence of a large number of blockages in the equalizing holes 21.

[0035] Preferably, a rotating groove 20 is provided on the bottom outer wall of the equalizing plate 17, and a rotating tube 22 is fixedly connected to the circumferential inner wall of the first gear 23. The end of the rotating tube 22 away from the first gear 23 is rotatably connected to the rotating groove 20, thereby ensuring the stability of the rotating tube 22 and the first gear 23 during rotation.

[0036] Preferably, a fixing plate 7 is fixedly connected to the bottom outer wall of the transverse plate 2 , and the rotating rod 35 is rotatably connected to the fixing plate 7 , thereby ensuring the stability of the rotating rod 35 during rotation.

[0037] Preferably, the cooling component includes an inclined column fixedly connected to the outer wall of the bottom of the horizontal plate 2, one end of the inclined column is fixedly connected to the first cooling sleeve 12, the top outer wall of the first cooling sleeve 12 is provided with a liquid inlet hole, the circumferential outer wall of the rotating rod 35 is in contact with the circumferential inner wall of the first cooling sleeve 12, a second cooling sleeve 16 is arranged below the first cooling sleeve 12, the second cooling sleeve 16 is located in the middle of the two sets of driving gears 13, the circumferential outer wall of the first cooling sleeve 12 is plugged with a guide pipe 14, and the guide pipe 14 is away from the first cooling sleeve 12. One end of the sleeve 12 is connected to the second cooling sleeve 16. Before the centrifuge is started, the external water pipe is connected to the liquid inlet hole at the top of the first cooling sleeve 12, so that the first cooling sleeve 12 and the second cooling sleeve 16 can be continuously replenished with fluid. At the same time, as a large amount of cold water is introduced into the first cooling sleeve 12 and the second cooling sleeve 16, continuous heat exchange can be carried out with the rotating rod 35 at the output end of the motor 4, thereby reducing the operating temperature of the rotating rod 35 and the motor 4, and effectively extending the service life of the motor 4 and the rotating rod 35.

[0038] Preferably, a spiral blade 36 is fixedly connected to the inside of the first cooling sleeve 12, and the spiral blade 36 is located below the liquid inlet. The spiral blade 36 can make the cold water flow in a spiral shape, which not only prolongs the heat exchange time with the rotating rod 35, but also allows the cold water to fully exchange heat with the rotating rod 35, thereby improving the cooling effect of the first cooling sleeve 12 on the rotating rod 35.

[0039] Preferably, the circumferential outer wall of the second cooling sleeve 16 is provided with spray holes distributed at equal distances, and a spray head 37 is fixedly connected to the inside of the spray hole. The cold water after heat exchange will be thrown out through the spray head 37, and the thrown water droplets will contact with part of the molten steel droplets, thereby pre-cooling the molten steel droplets and accelerating the cooling and forming speed of the molten steel droplets.

[0040] Preferably, the circumferential outer wall of the rotating rod 35 is fixedly connected to the shaft sleeve 38, and the circumferential outer wall of the shaft sleeve 38 is fixedly connected to the fan blades 15. During the process of swinging out the cold water, the fan blades 15 thereunder will also rotate together, which can not only diffuse the cold water droplets, so that the cold water droplets cover a wider area and contact more steel droplets, but also blow the high-temperature water mist generated by the cooling of the steel droplets in the water pool 1 downward, avoiding the situation where a large amount of high-temperature water mist rises and contacts the cooling component, the rotating rod 35 and the motor 4, resulting in a decrease in heat exchange effect and a decrease in service life.

[0041] Preferably, the cross-section of the bottom inner wall of the centrifugal brick barrel 5 is arched. The arched structure can concentrate the molten steel and throw it out from the centrifugal hole 9. At the same time, it can also effectively prevent the centrifugal brick barrel 5 from sinking, deforming and cracking due to gravity during rotation during use, resulting in a reduction in the life of the centrifugal brick barrel 5.

[0042] In summary, with the help of the above-mentioned technical scheme of the present invention, when the staff needs to produce cast steel shots, they can first start the motor 4 and pour the molten cast steel from the pouring port 3 into the centrifugal brick cylinder 5. In the process of the staff pouring the molten cast steel, it will first contact the equalizing plate 17. The equalizing holes 21 on the equalizing plate 17 can weaken the impact force generated when the molten cast steel is poured, which has a good anti-splashing effect. At the same time, the equalizing plate 17 is horizontally arranged inside the centrifugal brick cylinder 5, so that the molten cast steel can fall evenly into the centrifugal brick cylinder 5, avoiding a large amount of molten steel from falling into a certain area of ​​the centrifugal brick cylinder 5 at the same time, causing the centrifugal brick cylinder 5 to be unevenly stressed during the centrifugal process, resulting in a large difference in the size of the molten steel droplets thrown out, which plays a certain balance. The effect of centrifugal rotation stress ensures the quality of the output steel shot, and the cross-sections of the equalizing holes 21 opened on the equalizing plate 17 are all oblique, so that a certain centrifugal force can be generated during the rotation of the centrifugal brick cylinder 5, accelerating the droplets to detach from the equalizing holes 21 and fall into the inside of the centrifugal brick cylinder 5, avoiding the occurrence of a large number of blockages in the equalizing holes 21. When the molten steel flows into the bottom of the centrifugal brick cylinder 5, the starting of the motor 4 can drive the rotating rod 35 and the two sets of driving gears 13 to rotate. When the two sets of driving gears 13 rotate, the gear ring 10 meshing with them can be driven to rotate together. The rotation of the gear ring 10 can drive the entire centrifugal brick cylinder 5 to rotate together to perform centrifugal injection. When the centrifugal brick cylinder 5 rotates, the support frame 11 fixed on the top of it will also rotate accordingly. The ring gear plate 32 can be driven to rotate through the rotation of the support frame 11, and the ring gear plate 32 is meshed with the fifth gear 33, thereby driving the fifth gear 33 and the rotating rod 18 to rotate. During the rotation of the rotating rod 18, the fourth gear 30 at the bottom thereof can be driven to rotate. Since the tooth groove portion 3001 on the outer wall of the fourth gear 30 has only three groups, intermittent meshing with the second gear 28 can be achieved, thereby ensuring that the second gear 28 rotates intermittently, and through the rotation of the second gear 28 and the mutual meshing transmission between the third gear 29 and the first gear 23, the ring frame 25 and the baffle plate 26 can be driven to make intermittent circular motion, thereby realizing intermittent blocking of part of the centrifugal hole 9, satisfying people's demand for intermittent transmission of molten steel. In order to meet the need of injection, the external water pipe is connected to the liquid inlet hole at the top of the first cooling sleeve 12 before the centrifuge is started, so that the first cooling sleeve 12 and the second cooling sleeve 16 can be continuously replenished with liquid. At the same time, as a large amount of cold water is introduced into the first cooling sleeve 12 and the second cooling sleeve 16, continuous heat exchange can be carried out with the rotating rod 35 at the output end of the motor 4, thereby reducing the operating temperature of the rotating rod 35 and the motor 4, and effectively extending the service life of the motor 4 and the rotating rod 35. The spiral blades 36 arranged inside the first cooling sleeve 12 can make the cold water flow in a spiral shape, which not only extends the heat exchange time with the rotating rod 35, but also allows the cold water to fully exchange heat with the rotating rod 35, thereby improving the cooling effect of the first cooling sleeve 12 on the rotating rod 35.Finally, the cold water after heat exchange will be thrown out through the nozzle 37, and the thrown water droplets will contact some of the molten steel droplets, so as to pre-cool the molten steel droplets and speed up the cooling and forming speed of the molten steel droplets. In the process of throwing out the cold water, the fan blades 15 below it will also rotate together, which can not only diffuse the cold water droplets, so that the cold water droplets cover a wider area and contact more molten steel droplets, but also blow the high-temperature water mist generated by the cooling of the molten steel droplets in the water pool 1 downward, avoiding the situation where a large amount of high-temperature water mist rises and contacts the cooling component, the rotating rod 35 and the motor 4, resulting in a decrease in heat exchange effect and a decrease in service life.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
