A bottom-blown furnace support device for smelting

Abstract

This invention discloses a bottom-blown furnace support device for smelting, comprising a base; a mounting seat disposed above the base and hinged to the base; a swing drive assembly for driving the mounting seat to swing up and down along the hinge point with the base; a bottom-blown furnace body mounted above the mounting seat, the body having a slag outlet; a bracket mounted on the mounting seat and located below the slag outlet; and a lifting assembly for synchronously driving the bracket to move upward when the body is rotated. By setting up the bracket, swing drive assembly, and lifting assembly, during slag discharge, the swing drive assembly drives the body to swing, and simultaneously, during the body's swing, the lifting assembly drives the bracket to move upward. This ensures that during slag discharge, the slag inside the body can fully fall from the slag outlet, achieving a complete slag discharge operation.

Description

Technical Field

[0001] This invention relates to the field of bottom-blown furnace equipment technology, specifically to a bottom-blown furnace support device for smelting. Background Technology

[0002] The oxygen bottom-blown smelting-blast furnace reduction lead smelting process is a new lead smelting technology independently developed in my country. Its core is to react oxidation and reduction in different smelting processes. This process can effectively solve the pollution problems of SO2 acid production and lead dust in lead smelting flue gas. It has the characteristics of simple process flow, good environment, and clean production. In the oxygen bottom-blown smelting-blast furnace reduction lead smelting process, the oxygen bottom-blown smelting furnace is an indispensable smelting equipment.

[0003] A search of Chinese patent number CN208776803U reveals a three-stage support horizontal bottom-blown furnace for non-ferrous metal smelting. It includes a furnace body, a transmission device, and three sets of support devices. These three sets of support devices are asymmetrically arranged outside the furnace body. The transmission device is located at one end of the furnace body and drives the furnace body to rotate on the support devices. This horizontal bottom-blown furnace mechanism is scientifically sound and reasonable; it can support the furnace body using a three-stage support system even with an extended furnace body length, ensuring normal and stable operation of the furnace, increasing output, reducing the cost of purchasing a new two-stage support bottom-blown furnace, shortening the construction cycle, and effectively improving the economic benefits of the enterprise.

[0004] In the aforementioned prior art horizontal bottom-blown furnace, slag is collected by falling from the slag outlet due to gravity. However, this method is problematic because the slag has dead zones, making it difficult for it to fall smoothly and fully from the slag outlet for collection.

[0005] To address the aforementioned issues, we propose a bottom-blown furnace support device for smelting. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a support device for a bottom-blown furnace for smelting. To address the technical problem mentioned in the background art of the prior art where, during slag removal in a horizontal bottom-blown furnace, the slag relies on gravity to fall from the slag outlet for collection, and this method suffers from dead zones in the slag, resulting in insufficient and unsmooth slag fall from the outlet for collection, the present invention provides the following technical solution:

[0007] This invention provides a bottom-blown furnace support device for smelting, comprising:

[0008] base;

[0009] The mounting base is located above the base and hinged to the base;

[0010] A swing drive assembly is used to drive the mounting base to swing up and down along the hinge point between it and the base.

[0011] The main body of the bottom-blown furnace is installed above the mounting base, and the main body is provided with a slag outlet;

[0012] A bracket is installed on the mounting base and located below the slag outlet;

[0013] A lifting assembly is used to synchronously drive the bracket to move upward when the body is flipped.

[0014] In the bottom-blown furnace support device for smelting described above, the swing drive assembly includes:

[0015] Multiple support rods are vertically installed at one end of the base near the slag outlet, and the mounting base is hinged to the upper end of the support rods;

[0016] A support is provided on the base;

[0017] A rotating disk is rotatably connected to the support.

[0018] A hinge rod is hinged to the mounting base, and its lower end is rotatably connected to the end face of the rotating disk;

[0019] A rotating unit is used to drive the rotating disk to rotate reciprocally.

[0020] In the bottom-blown furnace support device for smelting described above, the rotating unit includes:

[0021] The gear is mounted on the rotating disk and is coaxial with the rotating disk;

[0022] The hydraulic cylinder is horizontally mounted on the base;

[0023] The rack column is horizontally fixed to the telescopic rod of the hydraulic cylinder and meshes externally with the gear.

[0024] In the bottom-blown furnace support device for smelting described above, each end of the mounting base is provided with a roller support, and multiple rollers are rotatably connected to the roller support. An annular rolling ring is fitted on the main body, and an annular rolling groove is coaxially provided on the annular rolling ring, in which the rollers roll.

[0025] In the bottom-blown furnace support device for smelting described above, the lifting assembly includes:

[0026] A fixed arm is located on one end of the base near the slag outlet;

[0027] The first hinge rod is hinged to the fixed arm;

[0028] The second hinge rod is hinged to the fixed arm. The vertical section of the bracket is hinged together with the ends of the first and second hinge rods away from the fixed arm. One end of the second hinge rod protrudes from the fixed arm and is hinged to a connecting rod. The end of the connecting rod away from the second hinge rod is hinged to the mounting base.

[0029] In the bottom-blown furnace support device for smelting described above, the length of the second hinge rod protruding from the fixed arm end is no more than half the length of the second hinge rod.

[0030] In the bottom-blown furnace support device for smelting described above, the vertical section of the bracket is parallel to the fixed arm.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up a bracket, a swing drive assembly, and a lifting assembly, during slag discharge, the swing drive assembly drives the main body to swing, and at the same time, when the main body swings, the lifting assembly drives the bracket to move upward. This allows the slag inside the main body to fall fully from the slag discharge port during slag discharge, achieving full slag discharge. The vertical section of the bracket, the first hinge rod, the second hinge rod, and the fixed arm form a parallel four-bar linkage mechanism. When the first hinge rod or the second hinge rod swings, it will drive the horizontal section of the bracket to move upward and generate lateral displacement, thereby lifting the collecting device and raising it to the slag discharge position. Below the outlet, during discharge, the slag inside the body will fall from the slag outlet into the collection device. On the one hand, this allows the slag to fall smoothly from the slag outlet, achieving full collection of the slag. On the other hand, by lifting the collection device, the phenomenon of slag entanglement and splashing during the falling process is reduced, thus improving the slag collection efficiency. The structure is simple and can be automated. The length of the second hinge rod protruding from the fixed arm end is no more than half the length of the second hinge rod. This makes the lever arm lengths at both ends of the second hinge rod inconsistent. Therefore, when the second hinge rod swings, the swing amplitude can be amplified when the connecting rod drives the second hinge rod to swing, thereby increasing the swing stroke of the bracket.

Detailed Implementation

[0037] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example

[0038] Please see Figure 1-3A bottom-blown furnace support device for smelting includes a base 9, a mounting seat 13 on top of the base 9, and multiple support rods 11 at one end of the base 9 along its length. One end of the mounting seat 13 along its length is hinged to the multiple support rods 11, allowing the mounting seat 13 to rotate up and down along the hinge point with the support rods 11. The body 2 of the bottom-blown furnace is mounted on top of the mounting seat 13, and the body 2 has a feed inlet 1. Additionally, roller supports 5 are provided at each end of the mounting seat 13 along its length, and rollers 15 are provided at each end of the mounting seat 13 along its width. The axial directions of the multiple rollers 15 are parallel. Furthermore, an annular rolling ring 3 is fitted at each end of the body 2 along its axial direction, and an annular rolling groove 14 is coaxially provided on the annular rolling ring 3. The rollers 15 engage with the annular rolling groove 14. The body 2 can roll within the annular rolling groove 14, allowing it to rotate on the mounting base 13. One end of the body 2 corresponding to the support rod 11 has a slag outlet 4, from which the processed slag falls and is collected. The base 9 has a fixed arm 6 at one end corresponding to the slag outlet 4. A first hinge rod and a second hinge rod 8 are sequentially hinged from top to bottom on the fixed arm 6. A bracket 7 is located below the slag outlet 4, consisting of a horizontal section and a vertical section perpendicular to each other. The vertical section of the bracket 7 is hinged to the end of the first hinge rod and the second hinge rod 8 away from the fixed arm 6. The horizontal section of the bracket 7 is used to place a collection device, which collects the slag falling from the slag outlet. The fixed arm 6 has openings for the first hinge rod and the second hinge rod... 8. A swing-through clearance groove allows free movement. One end of the second hinge rod 8 protrudes from the fixed arm 6 and is hinged to a connecting rod 10. The end of the connecting rod 10 away from the second hinge rod 8 is hinged to the mounting base 13. The vertical section of the bracket 7, the first hinge rod, the second hinge rod, and the fixed arm 6 form a parallel four-bar linkage. When the first or second hinge rod swings, it will drive the horizontal section of the bracket upward and generate lateral displacement, thereby lifting the collecting device and raising it below the slag outlet 4. The end of the mounting base 13 away from the fixed arm 6 is hinged to a hinge rod 19. A support 18 is also provided on the base 9. A rotating disk 20 is horizontally rotatably connected to the support 18. The rotating disk 20 can, of course, be rotatably connected by installing bearings or other means. On the support 18, a gear 17 is mounted on the rotating disk 20. The gear 17 is coaxial with the rotating disk 20. The end of the hinge rod 19 furthest from the mounting base 13 is rotatably connected to the end face of the rotating disk 20. A fixed plate is provided on the base 9, and a hydraulic cylinder 12 is horizontally mounted on the fixed plate. A rack and pinion 16 is connected to the telescopic rod of the hydraulic cylinder 12. The rack and pinion 16 is engaged with the gear 17. Thus, when the telescopic rod of the hydraulic cylinder 12 extends or retracts, it drives the rack and pinion 16 to move horizontally, causing the rack and pinion 16 to mesh and rotate with the gear 17. This, in turn, drives the hinge rod 19 to swing, thereby driving the mounting base 13 to flip upwards along the hinge point with the support rod 11. When flipped upwards, the connecting rod 10 drives the second hinge rod 8 to swing, and the bracket 7 to move upwards.This allows the collecting device placed on the horizontal section of the bracket 7 to be raised below the slag outlet 4. During discharge, the slag inside the body 2 will fall from the outlet into the collecting device. This ensures the slag falls smoothly and completely from the outlet 4, achieving thorough collection. Furthermore, by raising the collecting device, the slag's entanglement and splashing during the fall are reduced, thus improving collection efficiency. The length of the second hinge rod 8 protruding from the fixed arm 6 is no more than half its length. This results in inconsistent lever arm lengths at both ends of the second hinge rod 8. Therefore, when the second hinge rod 8 swings, the connecting rod 10 amplifies the swing amplitude, increasing the bracket's swing stroke.
