Description

Technical Field

[0001] The present invention belongs to the technical field of molten iron composition analysis devices in front of blast furnaces, and specifically relates to a molten iron composition analysis device in front of blast furnaces. Background Art

[0002] The rapid thermal analysis technology of molten iron composition in front of the furnace takes the solidification temperature curve of the cast iron structure formation process as the measured object, and the computer analyzes the solidification temperature curve to calculate the carbon equivalent, carbon content, silicon content and other indicators of the molten iron. It is a mature and reliable determination method.

[0003] When the existing molten iron composition analysis device is in use, first, the sample cup for storing molten iron is fixed at the top of the fixed column, and then the analysis instrument is started. When the instrument shows that it is ready, the molten iron is poured into the sample cup. There is a detection strip in the sample cup. When the transmitted temperature signal exceeds a certain threshold (such as 1000 °C), the instrument automatically enters the measurement state. The instrument will record the solidification temperature curve of the molten iron and analyze various phase change characteristic parameters of the molten iron according to the curve, and then calculate the content of components such as carbon and silicon;

[0004] However, there are still some problems in the actual application of the above solution. Molten iron is usually heated to a very high temperature in the melting furnace, generally between 1350 and 1250 °C. Such a high temperature makes the molten iron have high energy and fluidity. Once poured into the sample cup, it is very easy to splash out due to impact and temperature difference. The splashed molten iron will fall onto the upper surface of the fixed disk and then cool and solidify, fixing together with the fixed disk. When cleaning, it needs to be strongly scraped with a scraper of the same steel material, which is time-consuming and laborious, resulting in low cleaning efficiency. At the same time, if not cleaned, during the long-term continuous use of the analysis device, the solidified matter of the molten iron accumulates too much on the fixed disk, greatly increasing the mass of the entire fixed disk. When transporting the analysis device for subsequent use, it will become extremely inconvenient.

[0005] Therefore, the present invention provides a molten iron composition analysis device in front of blast furnaces. Summary of the Invention

When the first guide block drives the first motor to slide along the first trough body toward the fixed column, the fixed column will squeeze the two limit rings, causing the two limit rings to slide along the connecting column, thereby opening the two limit rings. Then, the two limit rings are reset under the action of the spring to automatically clamp the fixed column. The conical column fixed to the lower surface of each limit ring can crush the steel block on the fixed disk, achieving a better crushing effect. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0033] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] Embodiment 1

[0035] As Figures 1 to 7As shown in the figure, an analysis device for the composition of hot metal in front of a blast furnace according to an embodiment of the present invention includes an analyzer 1. One side of the analyzer 1 is fixedly connected with a connecting wire 11. One end of the connecting wire 11 away from the analyzer 1 is fixedly connected with a fixing column 12. The bottom end of the fixing column 12 is fixedly connected with a fixing plate 13. The top end of the fixing column 12 is fixedly connected with a fixing cylinder 110 for storing hot metal. A crushing component is arranged on one side of the fixing column 12. The crushing component includes a cross plate 14 fixedly connected to one side of the fixing plate 13. A first motor 17 is slidably connected to the cross plate 14. The output end of the first motor 17 is fixedly connected with a fixing shaft 4. The fixing shaft 4 is drivingly connected with a positioning shaft 44. The positioning shaft 44 is a reciprocating screw. A sliding plate 45 is slidably connected to the circumferential surface of the positioning shaft 44. Two limiting rings 47 are slidably connected to one side of the sliding plate 45. A plurality of conical columns 411 are fixedly connected to the lower surface of the two limiting rings 47. The plurality of conical columns 411 are used for crushing steel blocks on the upper surface of the fixing plate 13.

[0036] Specifically, hot metal is usually heated to a very high temperature in a melting furnace, generally between 1350 and 1250 °C. Such a high temperature makes the hot metal have high energy and fluidity. Once poured into a sample cup, it is very easy to splash due to impact and temperature difference. The splashed hot metal will fall onto the upper surface of the fixing plate 13 and then cool and solidify, fixing together with the fixing plate 13. When cleaning, it is necessary to use a scraper made of the same steel material to strongly remove it, which is time-consuming and laborious, resulting in a low cleaning efficiency problem.

[0037] Therefore, the present invention solves this problem by setting a certain structure. First, connect the analyzer 1 with the fixing column 12 through the connecting wire 11, then pour the hot metal into the fixing cylinder 110 and perform detection through analysis. After the detection is completed, if there are steel blocks formed by splashed hot metal on the fixing plate 13, they can be pretreated through the crushing component. First, slide the first motor 17 close to the fixing column 12, then the two limiting rings 47 will clamp the fixing column 12. After clamping, start the first motor 17, and its output end drives the fixing shaft 4 to rotate. Since the fixing shaft 4 is drivingly connected with the positioning shaft 44, it can drive the positioning shaft 44 (reciprocating screw) to rotate accordingly, driving the sliding plate 45 on the circumferential surface of the positioning shaft 44 to slide up and down. Driven by the sliding plate 45 of the two limiting rings 47, it makes a reciprocating motion, so that the conical columns 411 fixedly connected to the lower surface of the limiting rings 47 impact and crush the steel blocks on the fixing plate 13, ensuring that the steel blocks can be effectively crushed into small pieces or powder-like, which is convenient for subsequent sweeping and cleaning. Through the setting of the crushing component, the problem that it is difficult to clean large steel blocks on the fixing plate 13 is effectively solved.

[0038] It solves the problem that the splashed hot metal will fall onto the upper surface of the fixing plate 13, then cool and solidify, fixing together with the fixing plate 13. When cleaning, it is necessary to use a scraper made of the same steel material to strongly remove it, which is time-consuming and laborious, resulting in a low cleaning efficiency problem.

[0039] As shown Figure 1 in the figure, a connecting plate 19 is fixedly connected to one side of the first motor 17 in this embodiment. A fixing box 18 is fixedly connected to one side of the connecting plate 19. A slag removing agent is stored in the fixing box 18. Spray assemblies are arranged on both sides of the fixing box 18. The spray assemblies are used to spray the slag removing agent on the fixing plate 13.

[0040] Specifically, the fixing box 18 added beside the first motor 17 can evenly spray the stored slag removing agent on the fixing plate 13 through the spray assemblies. When the steel block is broken, the spray assemblies work simultaneously to ensure that the slag removing agent covers the steel block fragments, effectively softening the steel block, improving the crushing efficiency. At the same time, it can also prevent the steel powder from being raised during the crushing process. The slag removing agent can also play a role in adsorbing the steel powder, protecting the detection working environment.

[0041] As shown Figure 4 in the figure, an extrusion member is arranged in the fixing box 18 of this embodiment. Limiting blocks 3 are fixedly connected to both sides of the first motor 17. Connecting pipes 31 are fixedly connected to both sides of the fixing box 18. Each limiting block 3 is fixedly connected to the corresponding connecting pipe 31. The extrusion member is used to extrude the slag removing agent into the connecting pipe 31. A fixing plate 32 is fixedly connected to one end of each connecting pipe 31 away from the limiting block 3. A plurality of spray holes 33 are formed on one side of the two fixing plates 32 close to each other.

[0042] Specifically, inside the fixing box 18, the function of the extrusion member is to extrude the slag removing agent into the connecting pipe 31 fixedly connected to the limiting block 3. As the first motor 17 operates, the extrusion member is driven to generate pressure to push the slag removing agent to the other end of the connecting pipe 31, so as to spray out from the spray holes 33 on the two fixing plates 32 at the ends of the two connecting pipes 31, enabling the slag removing agent to be evenly and efficiently sprayed on the fixing plate 13, improving the uniformity and coverage rate of spraying. In addition, by spraying the slag removing agent to soften the steel block, the working efficiency of crushing and the slag removing effect are improved.

[0043] As shown Figure 5 in the figure, a first cavity 416 is formed on one side of the fixing box 18 close to the connecting plate 19. A positioning column 418 is arranged in the first cavity 416. The positioning column 418 is fixedly connected to the fixed shaft 4. The positioning column 418 is a reciprocating screw rod. A rotating plate 417 is slidably connected to the circumferential surface of the positioning column 418.

[0044] Specifically, in the first cavity 416 within the fixed box 18, the positioning post 418 serves as a reciprocating screw. The positioning post 418 is firmly connected to the fixed shaft 4. When the fixed shaft 4 rotates to drive the positioning post 418 to rotate, the positioning post 418 will drive the rotating plate 417 to slide up and down reciprocally. Since the positioning post 418 is a reciprocating screw, the reciprocating sliding of the rotating plate 417 within the first cavity 416 will squeeze the slag removal agent within the first cavity 416, causing the slag removal agent to be sprayed onto the fixed disk 13, thereby improving the overall slag removal efficiency.

[0045] As Figure 6 shown, at the output end of the first motor 17 in this embodiment, a fixed shaft 4 is fixedly connected. On the circumferential surface of the fixed shaft 4, a first runner 41 is fixedly connected. The first runner 41 is drivingly connected to a first steel belt 42. One end of the first steel belt 42 far from the first runner 41 is drivingly connected to a second runner 43, and the second runner 43 is fixedly connected to the positioning shaft 44.

[0046] Specifically, after the first motor 17 is started, it will drive the fixed shaft 4 at its output end to rotate. The rotation of the fixed shaft 4 will drive the first runner 41 fixedly connected to its output end. The first runner 41 drives the first steel belt 42 to transmit power. The transmission of the first steel belt 42 drives the second runner 43 to transmit power. The second runner 43 can drive the positioning shaft 44 to rotate, thereby driving the sliding plate 45 to move up and down reciprocally and driving the conical column 411 to perform crushing work.

[0047] As Figure 7 shown, on the circumferential surface of the positioning shaft 44 in this embodiment, a slider 415 is slidably connected. On one side of the slider 415, a sliding plate 45 is fixedly connected. On one side of the sliding plate 45, a second groove 46 is provided. Inside the second groove 46, a connecting column 48 is fixedly connected. At the position of the sliding plate 45 corresponding to the connecting column 48, a positioning hole 410 is provided. The connecting column 48 is fixedly connected within the positioning hole 410. On the circumferential surface of the connecting column 48, two limiting rings 47 are slidably connected. Between each limiting ring 47 and the inner wall of the second groove 46, a spring 49 is fixedly connected.

[0048] Specifically, after the positioning shaft 44 rotates, it drives the slider 415 slidably connected to its circumferential surface through the reciprocating screw provided on its circumferential surface, thereby driving the sliding plate 45 fixedly connected to one side of the slider 415 to move up and down. When the first guide block 16 drives the first motor 17 to slide along the first groove 15 towards the fixed column 12, at this time, the fixed column 12 will squeeze the two limiting rings 47, causing the two limiting rings 47 to slide along the connecting column 48, thereby causing the two limiting rings 47 to open. Then, under the action of the spring 49, the two limiting rings 47 reset to automatically clamp the fixed column 12. The conical columns 411 fixedly connected to the lower surfaces of each limiting ring 47 can crush the steel blocks on the fixed disk 13, achieving a better crushing effect.

[0049] As Figure 7As shown, at one end of each limiting ring 47 away from the sliding plate 45, a connecting rod 412 is fixedly connected, and the cross-sections of the two connecting rods 412 are in an inverted V shape.

[0050] Specifically, by fixedly connecting a connecting rod 412 at one end of each limiting ring 47 away from the sliding plate 45, and the cross-sections of the two connecting rods 412 being in an inverted V shape, during the process of the first guide block 16 driving the connecting rod 412 to move towards the fixed column 12, the limiting ring 47 can be easily opened, playing a role of pre-guidance and assisting in the clamping of the limiting ring 47.

[0051] As Figure 6 shown, on one side of the fixed box 18 of this embodiment, a fixed frame 413 is fixedly connected, a fixed slot 414 is opened on one side of the fixed frame 413, and the slider 415 can stably slide along the fixed slot 414.

[0052] Specifically, by fixedly connecting a fixed frame 413 on one side of the fixed frame 413, during the process of the slider 415 driving the sliding plate 45 to slide up and down along the positioning shaft 44, the slider 415 can stably slide along the fixed slot 414, thereby achieving the improvement of the sliding stability of the sliding plate 45 and making the operation of the device more stable.

[0053] As Figure 1 shown, at the bottom end of the first motor 17 of this embodiment, a first guide block 16 is fixedly connected, a first groove 15 is opened on the upper surface of the cross plate 14, and the first motor 17 can slide along the first groove 15 through the first guide block 16.

[0054] Specifically, by opening a first groove 15 on the upper surface of the cross plate 14, when the crushing component needs to be used, by starting the first guide block 16 on the cross plate 14, because the first groove 15 is an electric guide rail, the first guide block 16 is electrically connected to the first groove 15, so that driving the first guide block 16 to slide along the first groove 15 can drive the first motor 17 to approach the fixed column 12.

[0055] Embodiment Two

[0056] As Figures 1 to 7 shown, compared with Embodiment One, another implementation manner of the present invention is: at the top end of the fixed column 12, a chassis 2 is fixedly connected, several card slots 28 are opened on the upper surface of the chassis 2, several card blocks 27 are fixedly connected to the lower surface of the fixed cylinder 110, and the several card blocks 27 can be inserted into the card slots 28. A connection block 21 is fixedly connected to the upper surface of the chassis 2, a jack 22 is opened on one side of the connection block 21, a telescopic rod 23 is fixedly connected to one side of the chassis 2, a compression spring 24 is sleeved on the circumferential surface of the telescopic rod 23, a plug rod 25 is fixedly connected to the end of the telescopic rod 23 away from the chassis 2, and a fixing hole 26 is opened at the position of the fixed cylinder 110 corresponding to the plug rod 25.

[0057] Specifically, by aligning and inserting the clamping block 27 on the lower surface of the fixed cylinder 110 into the clamping groove 28 on the upper surface of the chassis 2, preliminary positioning and connection are achieved. Subsequently, by using the telescopic rod 23 and the insertion rod 25 on one side of the chassis 2, under the elastic force of the compression spring 24, the insertion rod 25 can smoothly insert into the corresponding fixing hole 26 and insertion hole 22 on the fixed cylinder 110, thus completing the firm connection between the fixed cylinder 110 and the chassis 2. Throughout this process, the cooperation between the clamping block 27 and the clamping groove 28 ensures the accuracy of the connection, enabling a fast and firm connection effect, improving the reliability and safety of the connection. At the same time, the use of the compression spring 24 enables the insertion rod 25 to automatically reset and insert into the fixing hole 26, making it very convenient to use.

[0058] Working principle: First, connect the analyzer 1 to the fixed column 12 through the connecting wire 11. Then, by aligning and inserting the clamping block 27 on the lower surface of the fixed cylinder 110 into the clamping groove 28 on the upper surface of the chassis 2, preliminary positioning and connection are achieved. Subsequently, by using the telescopic rod 23 and the insertion rod 25 on one side of the chassis 2, under the elastic force of the compression spring 24, the insertion rod 25 can smoothly insert into the corresponding fixing hole 26 and insertion hole 22 on the fixed cylinder 110, thus completing the firm connection between the fixed cylinder 110 and the chassis 2. Throughout this process, the cooperation between the clamping block 27 and the clamping groove 28 ensures the accuracy of the connection, enabling a fast and firm connection effect, improving the reliability and safety of the connection. At the same time, the use of the compression spring 24 enables the insertion rod 25 to automatically reset and insert into the fixing hole 26, making it very convenient to use.

[0059] After the fixed cylinder 110 is fixed, pour molten iron into the fixed cylinder 110 and conduct detection through analysis. After the detection is completed, if there are steel blocks formed by splashed molten iron solidifying on the fixed disk 13, they can be pretreated through the crushing assembly. First, by starting the first guide block 16 on the cross plate 14, since the first groove body 15 is an electric guide rail, the first guide block 16 is electrically connected to the first groove body 15, enabling the driving of the first guide block 16 to slide along the first groove body 15, which can drive the first motor 17 to approach the fixed column 12. Then, the two limiting rings 47 will clamp the fixed column 12. After clamping, start the first motor 17. After the first motor 17 starts, it will drive the fixed shaft 4 at its output end to rotate. The rotation of the fixed shaft 4 will drive the first runner 41 fixedly connected to its output end. The first runner 41 drives the first steel belt 42 to transmit. The transmission of the first steel belt 42 drives the second runner 43 to transmit. The second runner 43 can drive the positioning shaft 44 to rotate, and then drive the sliding plate 45 on the circumferential surface of the positioning shaft 44 to slide up and down.

[0060] After the positioning shaft 44 rotates, the reciprocating screw rod provided on its circumferential surface drives the slider 415 slidably connected to the circumferential surface, thereby driving the sliding plate 45 fixedly connected to one side of the slider 415 to move up and down. When the first guide block 16 drives the first motor 17 to slide along the first groove body 15 towards the fixed column 12, at this time, the fixed column 12 will squeeze the two limit rings 47, causing the two limit rings 47 to slide along the connecting column 48, so that the two limit rings 47 open. Then, the two limit rings 47 reset under the action of the spring 49 to automatically clamp the fixed column 12. The conical columns 411 fixedly connected to the lower surface of each limit ring 47 can impact and break the steel blocks on the fixed disk 13, ensuring that the steel blocks can be effectively broken into small pieces or powder-like shapes, which is convenient for subsequent cleaning. Through the setting of the crushing assembly, the problem that it is difficult to clean the large steel blocks on the fixed disk 13 is effectively solved;

[0061] The fixed box 18 added beside the first motor 17 can evenly spray the stored slag removal agent on the fixed disk 13 through the spray assembly. When the steel blocks are broken, the spray assembly works simultaneously to ensure that the slag removal agent covers the steel block fragments, effectively softening the steel blocks, improving the crushing efficiency, and at the same time preventing the steel powder from being raised during the crushing process. The slag removal agent can also play a role in adsorbing the steel powder, protecting the detection working environment;

[0062] Specifically, in the first cavity 416 of the fixed box 18, the positioning column 418 serves as a reciprocating screw rod. The positioning column 418 is firmly connected to the fixed shaft 4. When the fixed shaft 4 rotates to drive the positioning column 418 to rotate, the positioning column 418 will drive the rotating plate 417 to slide up and down reciprocally. Because the positioning column 418 is a reciprocating screw rod, the reciprocating sliding of the rotating plate 417 in the first cavity 416 will squeeze the slag removal agent in the first cavity 416, causing the slag removal agent to be sprayed on the fixed disk 13, improving the overall slag removal efficiency.

[0063] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
