Description

Technical Field

[0001] The invention belongs to the technical field of ferrovanadium smelting equipment, and in particular relates to a split furnace body for ferrovanadium production. Background Art

[0002] Currently, vanadium-ferroalloy smelting furnaces come in two types: tilting furnaces and straight-cylinder furnaces. In tilting furnaces, the material is melted, poured into molds, and cooled to form alloy ingots. In straight-cylinder furnaces, the material melts, cools, and forms alloy ingots within the furnace. In the current knotted process for straight-cylinder furnaces, the furnace bottom is constructed of magnesia bricks, which are then covered and knotted with magnesia sand and magnesia fireclay. The refractory lining is disposable: after smelting, the furnace is dismantled after cooling, and the knotted magnesia sand and magnesia fireclay lining are discarded. For example, Patent No. 201510474486.7, entitled "Method for Casting Lining of a Straight-Cylinder Furnace for Ferrovanadium Alloy Smelting," utilizes this type of straight-cylinder furnace. When unloading the material from a straight-cylinder furnace, a crane or other tilting mechanism is used to tilt the ingots. During this unloading process, not only the vanadium-ferroalloy but also the knotted material is dumped out. During this dumping process, the knotted material is impacted by the vanadium-ferroalloy, causing dust to fly and pollute the environment. Summary of the Invention

[0003] In view of this, it is necessary to provide a split type ferrovanadium production furnace body that reduces dust flying.

[0004] A split-type furnace body for ferrovanadium production includes a cylinder, a chassis, and a clamp. The lower end of the cylinder is clamped to the chassis. The edge of the chassis is provided with a circle of ribs. The inner diameter of the ribs is larger than the outer diameter of the cylinder. The side walls of the cylinder and the ribs are provided with a plurality of matching limit members, and the matching limit members form a group of limit assemblies. The clamp is clamped and connected to the limit assemblies. The side walls of the cylinder are also provided with a plurality of hanging ears for easy lifting.

[0005] Preferably, the fixture includes a limit frame, a bolt, a handle, and a gasket. The limit frame is sleeve-connected to the limit components on the corresponding positions of the cylinder and the retaining edge. A threaded hole is provided at the upper end of the limit frame, and the spiral is sleeve-connected to the threaded hole. The upper end of the spiral is connected to the handle, and the lower end of the spiral is connected to the gasket. When the cylinder and the chassis are connected, the gasket is screwed onto the limit component of the cylinder.

[0006] Preferably, the side of the limiting component close to the cylinder or the rib is gradually widened and thickened to enhance the bearing capacity of the limiting component.

[0007] Preferably, a reinforcing rib is provided on a side of the limiting component close to the cylinder or the rib to enhance the bearing capacity of the limiting component.

[0008] Preferably, the side walls of the chassis are provided with a plurality of hanging pin assemblies to facilitate lifting the chassis, and the hanging pin assemblies include two support plates and a latch, and the support plates are provided with pin holes, and both ends of the latch are sleeved in the pin holes.

[0009] Preferably, the number of the hanging ears, clamps, limit assemblies, and hanging pin assemblies is four.

[0010] Beneficial effects: When the split-type ferrovanadium production furnace of the present invention is in use, the cylinder is first placed on the chassis, and the limiting piece on the cylinder is aligned with the limiting piece on the retaining edge, and then the cylinder and the chassis are fixed by a clamp. Under the action of the clamp, the contact position between the bottom of the cylinder and the chassis will be effectively sealed. When the vanadium-iron alloy is taken out of the furnace, the hanging rope is first connected to the hanging ear, and then the clamp is removed, and the cylinder is slowly lifted. The vanadium-iron alloy will remain on the chassis, and the knotted material between the vanadium-iron alloy and the cylinder will fall in the vertical direction. Since the vanadium-iron alloy is not tipped over, the kinetic energy of the knotted material is much smaller than the kinetic energy of the tipping method. At the same time, the vanadium-iron alloy will not cause collision with the knotted material, which effectively suppresses the generation of dust. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In the figure: a split-type furnace body 10 for ferrovanadium production, a cylinder 20, a hanging ear 201, a chassis 30, a rib 301, a fixture 40, a limit frame 401, a bolt 402, a handle 403, a gasket 404, a limit assembly 50, a limit member 501, a hanging pin assembly 60, a support plate 601, and a latch 602. DETAILED DESCRIPTION

[0017] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following is a brief introduction to the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0018] Please see Figures 1 to 4 A split-type furnace body 10 for ferrovanadium production includes a cylinder 20, a chassis 30, and a clamp 40. The lower end of the cylinder 20 is clamped with the chassis 30. The edge of the chassis 30 is provided with a circle of ribs 301. The inner diameter of the ribs 301 is larger than the outer diameter of the cylinder 20. The side walls of the cylinder 20 and the ribs 301 are provided with a plurality of matching limit members 501, and the matching limit members 501 form a group of limit assemblies 50. The clamp 40 is clamped and connected with the limit assemblies 50. The side wall of the cylinder 20 is also provided with a plurality of hanging ears 201 for easy lifting.

[0019] Since the furnace body is to be used repeatedly, the cylinder 20 and the chassis 30 need to be matched repeatedly. The inner diameter of the rib 301 is larger than the outer diameter of the cylinder 20, which is conducive to the assembly of the cylinder 20. However, when the inner diameter of the rib 301 is larger than the outer diameter of the cylinder 20, the cylinder 20 is easy to slide in the chassis 30, and the cylinder 20 is not fixed to the chassis 30. When filling materials, the cylinder 20 may fall over. By providing matching limiters 501 on the side walls of the cylinder 20 and the rib 301, and engaging the limiter assembly 50 through the clamp 40, the cylinder 20 can be fixed to the chassis 30, and the materials will not flow out from the bottom of the cylinder 20. The cylinder 20 needs to be lifted by a hoist. Therefore, the side walls of the cylinder 20 need to be provided with hanging ears 201. By fixing ropes or the like to the hanging ears 201, the cylinder 20 can be lifted.

[0020] The clamp 40 is used to fix the limiting component 50, thereby fixing the cylinder 20 and the chassis 30. For example, if the limiting component 50 is two limiting plates facing each other, and there are pin holes on the limiting plates, then the clamp 40 is the latch 602. The limiting component 50 can also form a mortise and tenon structure or a lock with the clamp 40. The specific form of the clamp 40 is determined by the form of the limiting plate. When determining the form of the limiting plate and the clamp 40, the convenience and reliability of actual use should be considered. In a preferred embodiment, please refer to Figure 5 The fixture 40 includes a limit frame 401, a bolt 402, a handle 403, and a gasket 404. The limit frame 401 is sleeved and connected to the limit assembly 50 at the corresponding positions of the cylinder 20 and the retaining edge 301. A threaded hole is provided at the upper end of the limit frame 401, and the spiral is sleeved and connected to the threaded hole. The upper end of the spiral is connected to the handle 403, and the lower end of the spiral is connected to the gasket 404. When the cylinder 20 and the chassis 30 are connected, the gasket 404 is screwed onto the limit assembly 50 of the cylinder 20.

[0021] During use, the limit frame 401 is first placed over the limit assembly 50. Then, the handle 403 is rotated until the gasket 404 is tightly fitted against the limit assembly 50 and the limit frame 401 is immobile. In this manner, the multiple limit frames 401 prevent the barrel 20 from moving vertically or horizontally, nor from rotating. To remove, the reverse operation is performed. This embodiment is relatively simple to operate, highly reliable, and can be used repeatedly.

[0022] The stress on the connection between the stopper 501 and the cylinder 20 or the retaining edge 301 is relatively large. If things go on like this, the stopper 501 is prone to breakage or metal fatigue, which will affect the reliability of the equipment. Figure 3 In a preferred embodiment, the side of the limiting component 50 close to the cylinder 20 or the retaining edge 301 is gradually widened and thickened to enhance the bearing capacity of the limiting component 50. In another preferred embodiment, please refer to Figure 4 The side of the limiting component 50 close to the cylinder 20 or the retaining edge 301 is provided with a reinforcing rib to enhance the bearing capacity of the limiting component 50.

[0023] After the cylinder 20 is lifted, the vanadium-ferroalloy and bottom ash remain on the chassis 30. In some cases, such as due to site restrictions, the vanadium-ferroalloy cannot be moved on-site. In this case, it must be moved along with the chassis 30. In a preferred embodiment, the sidewalls of the chassis 30 are equipped with several hanging pin assemblies 60 to facilitate lifting the chassis 30. The hanging pin assemblies 60 include two support plates 601 and latches 602. The support plates 601 are provided with pin holes, and the ends of the latches 602 are inserted into the pin holes. The chassis 30 is moved by connecting the lifting device to the latches 602.

[0024] In a preferred embodiment, the number of the hanging ear 201, the clamp 40, the limiting assembly 50, and the hanging pin assembly 60 are all four.

[0025] The above disclosure is only a preferred embodiment of the present invention, and it is certainly not intended to limit the scope of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
