Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, and in particular to a spray gun armor for an Osmite furnace. Background Technology

[0002] The smelting process in the Ausmelt furnace mainly involves sending natural gas, oxygen, and air into the molten pool through a spray gun to stir and chemically react with concentrates and solvents, rapidly completing the sulfur-making and slag-making reactions.

[0003] The Osmite top-blown immersion lance process has been widely used in the commercial production of non-ferrous metals, precious metals, and various waste materials at high temperatures. During production in an Osmite furnace, in order to fully melt the metal, the lance must be inserted into the molten pool. The gas inside the lance has a strong stirring effect on the molten pool of the Osmite furnace. Because the Osmite furnace lance needs to be immersed in the high-temperature melt, the lance head is prone to burn-out. After long-term use, the lance body will deform, leading to accelerated burn-out of the lance head. Summary of the Invention

[0004] The purpose of this invention is to provide a spray gun armor for an Osmite furnace to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an Osmite furnace spray gun armor, applied to the spray gun barrel, comprising:

[0006] An armor assembly is disposed at the end of the spray gun barrel and is used to reinforce the end of the spray gun barrel.

[0007] A fastener is provided on the top of the armor assembly and is used to securely install the armor assembly and the spray gun barrel.

[0008] A closing component is disposed on top of the armor assembly and is used to protect the fasteners.

[0009] Preferably, the armor assembly includes:

[0010] An armor strip is provided on the outer wall of the spray gun barrel. The top of the armor strip has a slot for mounting a sealing component, and the inner wall of the slot has a screw hole for mounting a fastener.

[0011] The inner liner tube is fitted inside the spray gun barrel.

[0012] Preferably, the armor assembly further includes:

[0013] The bottom ends of the armor strip and the inner liner tube are fixedly connected to the top end of the connecting plate.

[0014] Preferably, the fastener includes:

[0015] A fixing bolt is inserted into a threaded hole, and a threaded groove is provided on the outer wall of the spray gun barrel, and the fixing bolt is threadedly inserted into the threaded groove.

[0016] Preferably, the enclosure component includes:

[0017] A sealing plate, which is interlocked with the slot.

[0018] Preferably, the enclosure component further includes:

[0019] A linkage plate, the bottom end of which is fixedly connected to the top end of a closed plate.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] This invention utilizes the design of the spray gun barrel, armor assembly, and fasteners. By simultaneously inserting fixing bolts into the screw holes and threaded grooves, the armor strips are fixedly connected to the spray gun barrel. This results in multiple armor strips being evenly distributed in the working area of ​​the spray gun barrel, thereby locally increasing the working surface thickness and strength at the end of the spray gun barrel. This enhances the corrosion resistance and erosion resistance of the spray gun barrel end, strengthens the spray gun barrel, effectively improves slag protection, and extends the service life of the spray gun barrel.

[0036] The inner liner tube 22 is fitted inside the spray gun barrel 1.

[0037] Armor Component 2 also includes:

[0038] The bottom ends of the connecting plate 23, the armor strip 21, and the inner liner tube 22 are all fixedly connected to the top end of the connecting plate 23.

[0039] The fasteners include:

[0040] The fixing bolt 3 is inserted into the screw hole 6. The outer wall of the spray gun barrel 1 is provided with a threaded groove 5, and the fixing bolt 3 is threadedly inserted into the threaded groove 5.

[0041] Furthermore, the spray gun barrel 1 is an existing Osmelt top-blown immersion spray gun, made of stainless steel. The armor strip 21 is a stainless steel metal strip with a thickness of 10mm. Multiple armor strips 21 are arranged at equal intervals around the outer wall of the end of the spray gun barrel 1. The connecting plate 23 is annular, and the bottom end of the armor strip 21 is welded to the top end of the connecting plate 23. The inner liner tube 22 is a round tube, and the outer diameter of the inner liner tube 22 corresponds to the inner diameter of the spray gun barrel 1. The threads on the inner wall of the threaded groove 5 mesh with the threads on the outer wall of the fixing bolt 3. The number of threaded grooves 5 corresponds to the number of armor strips 21. The armor strips 21 are vertically aligned, and the fixing bolts 3 are simultaneously inserted into the screw holes 6 and the threaded grooves 5 to fix the armor strips 21 to the spray gun barrel 1. The inner liner tube 22 is used to internally support the spray gun barrel 1. The setting of multiple armor strips 21 can locally increase the working surface thickness and strength of the spray gun barrel 1, increase the corrosion resistance and erosion resistance of the spray gun barrel 1, and enhance the strength of the spray gun barrel 1. At the same time, it can effectively enhance the protection of the spray gun barrel 1 against slag, extend the service life of the gun, reduce the number of times the spray gun head needs to be replaced each year, and reduce the replacement cost of the spray gun barrel 1.

[0042] In the second embodiment, the present invention provides as follows: Figure 1-6 The Osmelt furnace shown uses a spray gun armor applied to the spray gun barrel 1, comprising:

[0043] Armor assembly 2 is disposed at the end of the spray gun barrel 1 and is used to reinforce the end of the spray gun barrel 1.

[0044] The fastener is located on the top of the armor assembly 2 and is used to fix the armor assembly 2 and the spray gun barrel 1.

[0045] Enclosure component 4 is located on top of armor component 2 and is used to protect the fasteners.

[0046] Armor component 2 includes:

[0047] Armor strip 21 is provided on the outer wall of the spray gun barrel 1. The top of the armor strip 21 is provided with a slot 7 for installing the sealing component 4. The inner wall of the slot 7 is provided with a screw hole 6 for installing the fastener.

[0048] The inner liner tube 22 is fitted inside the spray gun barrel 1.

[0049] Enclosed component 4 includes:

[0050] The sealing plate 41 is inserted into the slot 7.

[0051] Enclosed component 4 also includes:

[0053] Furthermore, the size of the slot 7 corresponds to the size of the sealing plate 41, the number of sealing plates 41 corresponds to the number of armor strips 21, the linkage plate 42 is annular, and the contact parts of the sealing plate 41 and the linkage plate 42 are welded and fixed. The materials of the sealing plate 41 and the linkage plate 42 are the same as the materials of the armor strips 21. The contact part of the sealing plate 41 with the slot 7 is a rough surface. Thus, by inserting the sealing plate 41 into the interior of the slot 7, the sealing plate 41 and the slot 7 are stably installed under the action of mutual friction of the rough surfaces. By moving the linkage plate 42 towards the armor strip 21, the linkage plate 42 drives the sealing plate 41 into the interior of the slot 7, covering the screw hole 6 and the fixing bolt 3, reducing the damage to the fixing bolt 3 when the spray gun barrel 1 is used, thus facilitating the disassembly of the fixing bolt 3 when replacing the armor assembly 2.
