Description

Technical Field

[0001] This utility model relates to the field of blast furnace gas recovery technology, specifically a blast furnace top charge tank gas recovery device. Background Technology

[0002] Blast furnace ironmaking is a method of continuously producing liquid pig iron in a vertical reactor—the blast furnace—using coke, iron-bearing ore (natural lump ore, sinter, and pellets), and flux (limestone, dolomite). It is a crucial step in modern steel production. Modern blast furnace ironmaking evolved from the ancient vertical furnace method. Although many ironmaking methods have been researched and developed worldwide, blast furnace ironmaking remains the primary method of modern ironmaking due to its relatively simple process, high output, high labor productivity, and low energy consumption, accounting for over 95% of the world's total pig iron production.

[0003] The blast furnace top charge tank pressure equalization gas recovery system requires a power device for transporting gas. The technology of this system is now quite mature. Gas needs to be transported between the various devices in the system through pipelines. However, the gas output from the blast furnace top charge tank is often at a high pressure. When it flows in the pipeline, it will impact the inner wall of the pipeline, thus generating noise and causing the pipeline to vibrate. The continuous vibration of the pipeline will also affect the fixed structure of the pipeline. Ordinary fixed structures can easily loosen and fall off, creating safety hazards. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a gas recovery device for the top charge tank of an ironmaking blast furnace, which solves the problem that high-pressure gas flowing in the pipeline in a general blast furnace top charge tank pressure equalization gas recovery system generates noise and affects the fixed structure of the pipeline.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a gas recovery device for the top charge tank of an ironmaking blast furnace, comprising multiple working equipment units and multiple pipeline structures, wherein the multiple working equipment units are connected through the multiple pipeline structures;

[0006] The structures of the multiple pipeline mechanisms are all the same, and one of the pipeline mechanisms includes a pipeline structure and multiple fixed seat structures;

[0007] All of the aforementioned fixing base structures are identical in structure. One of the fixing base structures includes a rectangular fixing base plate. Device blocks are fixedly connected to both sides of the upper surface of the fixing base plate along its length direction. Device slots are respectively formed on the upper surfaces of the two device blocks along their length direction. Movable blocks that slide along the width direction of the fixing base plate are slidably connected inside the two device slots. Multiple first springs are respectively horizontally fixed between the two side surfaces of the movable blocks and the two side surfaces inside the device slots. Multiple columns are vertically fixedly connected to the top of the two movable blocks. Sliding seats are vertically slidably connected to the upper part of the outer surface of the multiple columns. Second springs are vertically fixedly connected between the bottom end of the multiple sliding seats and the upper surface of the movable blocks. A lower clamping ring with a semi-circular cross-section is horizontally fixedly connected to the top of the multiple sliding seats. An upper clamping ring is detachably installed at the top of the lower clamping ring.

[0008] The pipe structure is detachably installed between the upper and lower clamping rings of the plurality of fixed seat structures.

[0009] Furthermore, multiple guide holes are laterally opened through the side surfaces of both movable blocks, and guide rods are laterally fixedly connected inside the multiple guide holes. The two ends of the multiple guide rods are respectively fixedly connected to the two sides of the corresponding device groove.

[0010] Furthermore, the pipe structure includes an inner pipe, the outer surface of which is fitted with a sound insulation layer, and the outer surface of which is fitted with an outer pipe that is adapted to the inner diameter of the upper clamping ring and the lower clamping ring.

[0011] Furthermore, lower connecting strips and upper connecting strips are respectively fixedly connected laterally to both sides of the lower clamping ring and the upper clamping ring, and multiple corresponding connecting holes are vertically opened on the upper surfaces of the two lower connecting strips and the two upper connecting strips.

[0012] Furthermore, the upper surface of the fixing substrate has multiple vertically penetrating fixing holes at both the front and rear ends.

[0013] Furthermore, the top ends of the plurality of fixing holes are all expanded outward to form a recessed groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The blast furnace top charge gas recovery device, through the setting of a pipeline mechanism, includes a fixed seat structure, a movable block that can move laterally, and a sliding seat that can move vertically at the top of the movable block. Both are limited by a spring structure. When the pipe fixed to it vibrates, the force generated is distributed to multiple spring structures, thereby preventing damage to the overall structure of the fixed seat structure and ensuring its fixing effect and service life. At the same time, the pipeline structure in the pipeline mechanism is also equipped with a sound insulation layer, which can effectively reduce the noise generated by gas impact, thereby improving the practicality of the device.

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a gas recovery device for the top charge tank of an ironmaking blast furnace, comprising multiple working equipment units 1 and multiple pipeline structures 2, wherein the multiple working equipment units 1 are connected through multiple pipeline structures 2;

[0021] The structures of the multiple pipeline mechanisms 2 are all the same, and one of the pipeline mechanisms 2 includes a pipeline structure and multiple fixed seat structures;

[0022] The structures of the multiple fixed bases are all identical. One of the fixed base structures includes a rectangular fixed base 24. Device blocks 25 are fixedly connected to both sides of the upper surface of the fixed base 24 along its length. Device slots 26 are respectively opened on the upper surface of the two device blocks 25 along their length. Movable blocks 27 that slide along the width of the fixed base 24 are slidably connected inside the two device slots 26. Multiple first springs 28 are horizontally fixedly connected between the two side surfaces of the movable blocks 27 and the two side surfaces inside the device slots 26. Multiple columns 210 are vertically fixedly connected to the top of the two movable blocks 27. Sliding seats 211 are vertically slidably connected to the upper part of the outer surface of the multiple columns 210. Second springs 212 are vertically fixedly connected between the bottom end of the multiple sliding seats 211 and the upper surface of the movable blocks 27. A lower clamping ring 213 with a semi-circular cross section is horizontally fixedly connected to the top of the multiple sliding seats 211. An upper clamping ring 214 is detachably installed at the top of the lower clamping ring 213.

[0023] The pipe structure is detachably installed between the upper clamping ring 214 and the lower clamping ring 213 of multiple fixed seat structures.

[0024] The multiple working equipment units 1 in this device are multiple ejector tanks and dust collectors. The multiple working equipment units 1 are connected by a pipeline mechanism 2 and controlled by multiple valves, thereby forming a complete gas recovery system.

[0025] In the fixed base structure, two movable blocks 27 are slidably connected laterally inside the two device slots 26, and both sides are limited by the first spring 28. When the pipeline structure vibrates due to the gas inside, the movable block 27 will be driven to make corresponding displacement. Since it is limited by the first spring 28 on both sides, the force it receives will be buffered by the first spring 28, thus preventing the structure from loosening due to the force. The same applies to the column 210 at the top of the movable block 27 and the sliding seat 211 slidably connected to it. The two are supported by the second spring 212. The second spring 212 is perpendicular to the central axis of the first spring 28, so it can buffer the impact force in another direction. The two work together to enable the fixed base structure to support the pipeline structure stably for a long time.

[0026] Both movable blocks 27 have multiple guide holes that are laterally opened through their side surfaces. Guide rods 29 are laterally fixedly connected inside the multiple guide holes. The two ends of the multiple guide rods 29 are respectively fixedly connected to the two sides of the corresponding device slot 26.

[0027] The guide rod 29 guides and limits the movable block 27, so that it can only move inside the device slot 26 without deviation or other issues, thus ensuring the stability of the structure.

[0028] The pipe structure includes an inner pipe 21, an outer surface of which is fitted with a sound insulation layer 22, and an outer pipe 23 fitted on the outer surface of the sound insulation layer 22, which is adapted to the inner diameter of the upper clamping ring 214 and the lower clamping ring 213.

[0029] The pipe structure consists of three layers: inner pipe 21, sound insulation layer 22, and outer pipe 23. The inner pipe 21 and outer pipe 23 are made of metal, while the sound insulation layer 22 is made of sponge-like material, which can effectively insulate sound through its structure.

[0030] The lower clamping ring 213 and the upper clamping ring 214 are respectively horizontally fixedly connected to the lower connecting strip 215 and the upper connecting strip 216. The upper surfaces of the two lower connecting strips 215 and the two upper connecting strips 216 are vertically opened with multiple corresponding connecting holes 217.

[0031] The upper clamping ring 214 and the lower clamping ring 213 can clamp the pipe structure. In actual operation, after the pipe structure is placed on the lower clamping ring 213, the upper clamping ring 214 is placed on top of the pipe structure, and the multiple connecting holes 217 on the upper connecting strip 216 and the lower connecting strip 215 on both sides of the upper clamping ring 214 and the lower clamping ring 213 are aligned with each other. Then, multiple bolts can be used to fix the upper clamping ring 214 and the lower clamping ring 213, thereby completing the installation of both and fixing the pipe structure.

[0032] Multiple fixing holes 218 are vertically opened through the front and rear ends of the upper surface of the fixing substrate 24.

[0033] The tops of multiple fixing holes 218 are all expanded outward to form a recessed groove.

[0034] The fixing hole 218 is used to fix the fixing base plate 24. It can also be connected by bolt structure during fixing. The groove can play a certain role in fixing the bolt structure and prevent it from slipping.

[0035] During operation, the pipeline mechanism 2 of the device is equipped with a fixed base structure, which contains a movable block 27 that can move laterally. At the same time, the top of the movable block 27 is also equipped with a sliding seat 211 that can move vertically. Both are limited by a spring structure. When the pipe fixed on it vibrates, the force generated will be distributed to multiple spring structures, thereby preventing damage to the overall structure of the fixed base structure and ensuring its fixing effect and service life. At the same time, the pipeline structure in the pipeline mechanism is also equipped with a sound insulation layer 22, which can effectively reduce the noise generated by gas impact inside, thereby improving the practicality of the device.
