Description

Technical Field

[0001] The utility model relates to the field of ladle nozzle processing, and particularly relates to a jacket device for inlet and outlet nozzles. Background Technique

[0002] The ladle sliding nozzle is a control device for molten steel during the continuous casting process, generally composed of a driving device, a mechanical part, and a refractory part. Its working principle is to make the upper and lower slide bricks stagger through a sliding mechanism, thereby driving the opening and closing of the molten steel hole to adjust the flow rate of molten steel;

[0003] Among them, during the production process of the ladle nozzle, an iron shell sleeve needs to be installed on the outer surface of the nozzle. The iron shell sleeve can increase the overall strength and stability of the nozzle, reduce the risk of deformation and damage during use, and help protect the internal refractory layer, reduce mechanical damage and erosion of the refractory material, extend the service life of the nozzle, ensure the accuracy of the shape and size of the nozzle, help accurately control the flow rate and outflow speed of molten steel. The iron shell sleeve can also provide a better installation and fixing method, making the installation and disassembly of the nozzle on the ladle more convenient, fast, and safe. At the same time, to a certain extent, it helps to adjust the heat dissipation and heat preservation performance of the nozzle and maintain the temperature stability of molten steel;

[0004] However, in the existing production process of adding an iron shell sleeve to the nozzle, the iron shell sleeve is installed on the outer surface of the nozzle manually, and a rubber hammer is used to hammer the iron shell to make it installed in place. The manual pressing of the iron shell has low production efficiency. Moreover, the fire clay has a certain elasticity. If the hammering force is small, the fire clay cannot fill the gap between the iron shell and the product. If the hammering force is large, cracks will occur in the product, and the product consistency is poor. In addition, the processing efficiency of the existing externally added iron shell sleeve is relatively low and cannot meet the production requirements. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0026] Please refer to Figures 1 - 4As shown in the figure, the utility model relates to a device with a sleeve for water inlet and outlet, which comprises a pressing component 2, a water inlet / outlet 3 and an iron shell sleeve 4. The water inlet / outlet 3 is placed on the upper surface of the middle part of the pressing component 2, and the iron shell sleeve 4 is sleeved on the outer surface of the water inlet / outlet 3.

[0027] A conveying component 1 is slidably installed on the upper surface of the middle part of the pressing component 2. The conveying component 1 comprises a support plate 14 and limiting columns 16. The limiting columns 16 are symmetrically arranged on the upper surfaces of both ends of the support plate 14. Socket holes 15 are symmetrically formed on the side edges of both ends of the support plate 14. Annular grooves 18 are formed on the upper surfaces of both ends of the support plate 14 and at the bottom edges of the limiting columns 16. Wedge-shaped clamping grooves 13 are symmetrically formed inside the annular grooves 18. Insertion holes 11 are symmetrically formed inside the annular grooves 18. A tooth groove 12 is formed at the center of the bottom surface of the support plate 14. Wedge-shaped insertion slots 19 are symmetrically formed on the opposite surfaces of both ends of the support plate 14. A blanking component 17 is clamped inside the annular groove 18.

[0028] The blanking component 17 comprises insertion columns 171, first wedge-shaped blocks 172 and a jacking ring 173. The first wedge-shaped blocks 172 are symmetrically arranged on both sides of the bottom of the jacking ring 173. The insertion columns 171 are symmetrically arranged at the edges between the first wedge-shaped blocks 172 at both ends.

[0029] The pressing component 2 comprises a support frame 22, columns 24 and a hydraulic cylinder 28. The columns 24 are fixedly installed at the middle part of one side of the support frame 22. The hydraulic cylinder 28 is fixedly installed at the top of the column 24. The bottom end of the hydraulic cylinder 28 is fixedly connected with a pressing ring 27.

[0030] A transmission gear shaft 25 is rotationally clamped at the middle part of the top end of the support frame 22. Limiting rods 26 are symmetrically arranged on the upper surface of the support frame 22. Second wedge-shaped blocks 23 are symmetrically arranged at both ends of the top of the support frame 22. A driving motor 21 is fixedly installed at one side of the middle part of the support frame 22. One end of the transmission gear shaft 25 is fixedly connected with the driving motor 21.

[0031] In the utility model, the support plate 14 is slidably sleeved on the outer surface of the limiting rod 26 through the socket holes 15, which can ensure the stable sliding of the support plate 14 on the top of the support frame 22. The first wedge-shaped block 172 is clamped inside the annular groove 18 through the wedge-shaped clamping groove 13, which can play a role in limiting the lifting of the first wedge-shaped block 172. The insertion column 171 is inserted into the annular groove 18 through the insertion hole 11, which can further play a role in limiting the lifting of the jacking ring 173. The wedge-shaped insertion slot 19 is internally connected and communicated with the wedge-shaped clamping groove 13, so as to facilitate the second wedge-shaped block 23 to penetrate through the wedge-shaped insertion slot 19 and extrude the first wedge-shaped block 172 inside the wedge-shaped clamping groove 13 to rise.

[0032] The support plate 14 of the present utility model is meshed and connected with the socket hole 15 through the tooth grooves 12 at the bottom. When the socket hole 15 rotates, it can control the reciprocating movement of the support plate 14 on the upper surface of the support frame 22, so as to alternately convey the processed and unprocessed water outlets 3, ensuring the processing efficiency. The second wedge block 23 is slidably inserted into one end of the support plate 14 through the wedge slot 19, and can squeeze the blanking component 17 to drive the water outlet 3 on the upper surface to rise, facilitating the staff to blank the water outlet 3. The first wedge block 172 is movably abutted against the second wedge block 23 inside the wedge slot 13. The limiting column 16 at the top of the support plate 14 is aligned directly below the bottom of the pressing ring 27, so as to ensure that the pressing ring 27 accurately presses the top of the iron shell sleeve 4.

[0033] The working principle of the present utility model: When adding the iron shell sleeve 4 to the outer surface of the water outlet 3, first install the water outlet 3 on the outer surface of the limiting column 16, and then start the hydraulic cylinder 28 to drive the pressing ring 27 at the bottom to descend and press the top of the iron shell sleeve 4 below until the top of the iron shell sleeve 4 descends to be flush with the top of the water outlet 3, so that the iron shell sleeve 4 is completely sleeved on the outer surface of the water outlet 3. Then control the hydraulic cylinder 28 to drive the pressing ring 27 to rise and reset. Control the driving motor 21 to drive the transmission gear shaft 25 at one end to rotate, so that the transmission gear shaft 25 drives the support plate 14 meshed on the upper surface to slide horizontally, so that the support plate 14 slides on the outer surface of the limiting rod 26 to the other end, conveying the processed water outlet 3 away from below the pressing ring 27, and at the same time conveying the water outlet 3 at the other end to directly below the pressing ring 27, so as to continue the sleeve adding process. Then the staff removes the processed water outlet 3 far from below the pressing ring 27, so that the water outlet 3 is separated from the outer surface of the limiting column 16. Then install the new water outlet 3 on the outer surface of the limiting column 16 and wait for processing. Among them, during the process that the processed water outlet 3 moves away from the pressing ring 27 to the other end of the limiting rod 26, the second wedge block 23 is inserted into the wedge slot 19 and presses the bottom surface of the first wedge block 172. As the support plate 14 slides, the first wedge block 172 is blocked and drives the jacking ring 173 to rise. At the same time, the jacking ring 173 drives the water outlet 3 on the upper surface to rise, so that the bottom end of the water outlet 3 is far from the upper surface of the support plate 14, thus facilitating the staff to lift the bottom of the water outlet 3 to rise and separate from the limiting column 16, improving the efficiency of removing the water outlet 3. Therefore, through the coordinated operation between the conveying component 1 and the pressing component 2, it can ensure the qualified rate of adding the iron shell sleeve 4 to the outer surface of the water outlet 3, reduce the defective rate, and at the same time improve the production efficiency of adding the iron shell sleeve 4 to the outer surface of the water outlet 3.

[0034] The above has described an embodiment of the present utility model in detail, but the content is only the preferred embodiment of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of application of the present utility model should still fall within the scope covered by the patent of the present utility model.
