Description

Technical Field

[0001] This utility model relates to the field of metallurgical auxiliary equipment, specifically a device for breaking the shell layer on the surface of a high-temperature melt. Background Technology

[0002] In the metallurgical industry, the level of high-temperature melt is usually measured by inserting a gauge into the melt and observing the high-temperature melt adhering to the gauge surface. Due to fluctuations in furnace conditions and process control, a crust layer forms on the surface of the high-temperature melt. When the gauge needs to enter the smelting furnace to probe the melt, it must first penetrate the crust layer on the surface of the high-temperature melt. The traditional method of breaking the crust is for the operator to manually lift the gauge and use the impact force of the gauge falling freely to break the crust. At the same time, there is a risk of being burned by the high-temperature melt, burns when the negative pressure is unstable, or injuries from the spring-loaded steel wire rope during movement. Therefore, the present invention can solve the above problems and has certain industrial application value. At the same time, it provides a foundation for the development of an automatic measurement system for high-temperature melt level. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a device for breaking the shell layer on the surface of high-temperature melt. It is highly efficient and reliable, reducing the risk of burns from high-temperature melt, burns from unstable negative pressure, or injuries from the movement of steel wire ropes during operation. It is used to solve the problems of burns and injuries during high-intensity work.

[0004] To achieve the above objectives, the specific technical solution of this utility model is as follows: A device for breaking the surface shell layer of a high-temperature melt, characterized in that it includes a support, a measuring device, a shell-breaking hydraulic cylinder, a clamping frame, a clamping hydraulic cylinder, and a clamping mechanism. Two shell-breaking hydraulic cylinders are provided, with their tops vertically symmetrically positioned below the support. The clamping frame has the shape of three portal frames. The clamping frame is connected to the piston end of the shell-breaking hydraulic cylinders via lifting lugs. The two clamping hydraulic cylinders are horizontally positioned within the portal frames on both sides of the clamping frame. The bottom ends of the cylinder bodies of the two clamping hydraulic cylinders are fixedly connected to the outer frames of the two portal frames, and the top ends of the cylinder bodies are fixedly connected to the two side frames of the middle portal frame. Concentric circles are formed at the center of the support and the clamping frame.

[0005] It also includes a clamping mechanism, which is respectively set at the end of the hydraulic cylinder piston. The clamping mechanism consists of two symmetrical semi-clamping blocks with a semi-circular structure. Two connecting ears with through holes are evenly distributed on the vertical center line of one side of the semi-clamping block.

[0006] The support legs are fixed to the floor of the furnace.

[0007] The beneficial effect of this utility model is that when the measuring instrument is blocked by the surface crust layer when it enters the high-temperature melt, the piston rods of the clamping hydraulic cylinders symmetrically installed on both sides of the clamping frame extend and drive the clamping mechanism to move to the measuring instrument to achieve clamping. The piston rod of the shell-breaking hydraulic cylinder drives the clamping frame and clamping mechanism to descend unloaded to the point of cross-sectional change. As it descends further, the measuring instrument is pressed down synchronously until it breaks through the crust layer and enters the interior of the high-temperature melt. This reduces the risk of burns and injuries from manual operation and improves the detection rate. Attached Figure Description

Detailed Implementation

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] like Figure 1 , Figure 2 As shown, a device for breaking the surface shell of a high-temperature melt is characterized by comprising a support 1, a measuring device 2, a shell-breaking hydraulic cylinder 3, a clamping frame 4, a clamping hydraulic cylinder 5, and a clamping mechanism 6. Two shell-breaking hydraulic cylinders 3 are provided, with their tops vertically symmetrically positioned below the support 1. The clamping frame 4 has three portal frames. The clamping frame 4 is connected to the piston end of the shell-breaking hydraulic cylinder 3 via lifting lugs 4-1. The two clamping hydraulic cylinders 5 are horizontally positioned within the portal frames on both sides of the clamping frame 4. The bottom ends of the cylinder bodies of the two clamping hydraulic cylinders 5 are fixedly connected to the outer frames of the two portal frames on both sides, and the top ends of the cylinder bodies are fixedly connected to the two side frames of the middle portal frame. Concentric circles are formed at the center of the support 1 and the clamping frame 4.

[0012] like Figure 1As shown, it includes a clamping mechanism 6, which is respectively set at the end of the clamping hydraulic cylinder 5 piston. The clamping mechanism 6 is composed of two symmetrical semi-clamping blocks 6-1 with semi-circular structures. Two connecting ears 6-2 with through holes are evenly distributed on one side of the vertical center line of the semi-clamping block.

[0013] like Figure 2 , Figure 3 , Figure 4 As shown, the legs of the support 1 are fixed to the floor 11 of the furnace 7.

[0014] When this utility model is in use, when the measuring rod 2 enters the high-temperature melt and is blocked by the surface crust layer, the piston rods of the clamping hydraulic cylinders 5, which are symmetrically installed on both sides of the clamping frame 4, extend to drive the clamping mechanism to move to the measuring rod 2 to achieve clamping. The piston rod of the shell-breaking hydraulic cylinder 3 drives the clamping frame 4 and the clamping mechanism 6 to descend unloaded to the point of cross-sectional change. As it descends further, the measuring rod is pressed down synchronously until it breaks through the crust layer and enters the interior of the high-temperature melt.

[0015] The four legs of the support frame 1 are rigidly welded to the steel structure of the furnace top, ensuring support for the shell-breaking force. The shell-breaking hydraulic cylinder 3 is also rigidly welded to the support frame, similarly ensuring support for the shell-breaking force. The shell-breaking hydraulic cylinder 3, clamping frame 4, clamping hydraulic cylinder 5, and clamping mechanism 6 are rigidly connected as a whole, all using bolts. The stroke of the shell-breaking hydraulic cylinder 3 is selected based on the range of the molten metal level in the furnace, the total height of the gauge 2, the position of the frustum, and the installation height of the support frame.

[0016] Both the support 1 and the clamping frame have large through holes at their vertical center points, each larger than three times the diameter of the measuring tool, serving as channels for the measuring tool and the frustum section during the measurement of the melt surface and the shell breaking process.

[0017] The cylinder walls of the shell-breaking hydraulic cylinder 3 and the clamping hydraulic cylinder 5 have two oil inlet and outlet ports, which are used to connect the C and D ports of the three-position four-way solenoid valve 9 and the A and B ports of the two-position four-way solenoid valve 10. The hydraulic medium flow direction at the rear end of the three-position four-way solenoid valve 9, which is energized on the left and right sides and de-energized, drives the piston of the shell-breaking hydraulic cylinder 3 to descend, hold, and rise. This simultaneously drives the clamping frame 4, the clamping hydraulic cylinder 5, and the clamping mechanism 6 to form a rigid connected body and move as a whole. The hydraulic medium flow direction at the rear end of the two-position four-way solenoid valve 10, which is energized and de-energized, drives the piston of the clamping hydraulic cylinder 5 to retract and extend. This simultaneously drives the clamping and non-clamping states of the clamping structure 6.

[0018] To ensure the rigidity of the clamping mechanism, the symmetrical semicircles on both sides can evenly transmit the breaking force to the measuring plate and increase the contact area with the measuring plate's frustum, thus avoiding uneven force distribution that could cause the measuring plate to tilt and the clamping plate to deform.

[0019] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
