Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ore heating furnace, especially a protection device for ore heating furnace bellows pressure ring. BACKGROUND

[0002] Ore heating furnace is a high-temperature equipment, mainly used for reducing smelting ore, carbonaceous reducing agent and solvent and other raw materials, producing ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicon-manganese alloy and other ferroalloy, and is an important industrial raw material in metallurgical industry and chemical raw material such as calcium carbide.

[0003] At present, the bellows pressure ring in the ore heating furnace is easily extruded by external force in the use process, so that the bellows pressure ring is damaged, and the bellows does not have a heat dissipation effect, which is easy to produce high temperature in the use process, and affects the use of the bellows pressure ring.

[0004] Therefore, we propose a protection device for ore heating furnace bellows pressure ring to solve the above problems. UTILITY MODEL CONTENTS

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 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.

[0023] Please see Figures 1-4In this utility model, a protective device for the pressure ring of a corrugated pipe in a submerged arc furnace includes a pressure ring assembly 1. Several fixed cylinders 2 are fixedly connected to the outer surface of the pressure ring assembly 1. Each fixed cylinder 2 has an opening 3 on its outer surface. A buffer spring 4 is fixedly connected to the inner bottom wall of each fixed cylinder 2. A buffer limiting plate 5 is fixedly connected to the end of each buffer spring 4 away from the fixed cylinder 2. A connecting rod 6 is fixedly connected to the end of each buffer limiting plate 5 away from the buffer spring 4. The ends of the sixteen connecting rods 6 away from the buffer limiting plates 5 are jointly fixedly connected to a corrugated pipe body 7. A threaded water supply pipe 8 is provided on the inner side of the corrugated pipe body 7 and the outer side of the pressure ring assembly 1. The pressure ring assembly 1 and the corrugated pipe body 7 form a corrugated pipe pressure ring. The buffer assembly consisting of the fixed cylinders 2, openings 3, buffer springs 4, buffer limiting plates 5 and connecting rods 6 provides buffering and shock absorption protection for the corrugated pipe pressure ring.

[0024] The corrugated pipe body 7 includes an inner corrugated pipe 701, a high-temperature ceramic fiber layer 702, and an outer corrugated pipe 703. The inner corrugated pipe 701 is made of stainless steel, and the outer corrugated pipe 703 is made of alloy steel. A water inlet pipe 9 is fixedly connected to the left end of the threaded water pipe 8. The outer surface of the water inlet pipe 9 is fixedly connected to the outer surface of the corrugated pipe body 7. The inner corrugated pipe 701 and the outer corrugated pipe 703 form a high-strength corrugated pipe, achieving the pressure resistance of the corrugated pipe pressure ring and providing high strength. The high-temperature ceramic fiber layer 702 provides excellent protection by isolating external heat and preventing high temperatures from affecting the internal pressure ring assembly 1. The inlet pipe 9 delivers external cooling water to the threaded water pipe 8, where the cooling water absorbs the heat inside the bellows pressure ring. The cooling water is then discharged from the outlet pipe 10, thus cooling the bellows pressure ring and providing protection. The damper 11, in conjunction with the buffer spring 4, provides buffer protection for the bellows pressure ring, increasing the buffering effect.

[0025] The right end of the threaded water pipe 8 is fixedly connected to the outlet pipe 10. The outer surface of the outlet pipe 10 is fixedly connected to the outer surface of the corrugated pipe body 7. The inner bottom wall of each fixed cylinder 2 is fixedly connected to a damper 11. The ends of the sixteen dampers 11 away from the fixed cylinder 2 are respectively fixedly connected to the outer surfaces of the sixteen buffer limit plates 5.

[0026] The working principle of this utility model is as follows:

[0027] First, the bellows body 7 is composed of an inner bellows 701, a high-temperature ceramic fiber layer 702, and an outer bellows 703, which has pressure resistance and heat insulation effects. The buffer assembly, which consists of a fixed cylinder 2, an opening 3, a buffer spring 4, a buffer limit plate 5, and a connecting rod 6 between the bellows body 7 and the pressure ring assembly 1, provides shock absorption and buffering for the internal pressure ring assembly 1 and buffer protection for the bellows body 7. When the bellows pressure ring dissipates heat, external cooling water is transported into the threaded water supply pipe 8 through the water inlet pipe 9 to cool the bellows pressure ring. After the water absorbs the heat, it is discharged from the water outlet pipe 10.
