Description

Technical Field

[0001] The present invention relates to the technical field of regeneration furnaces, and specifically to a thermal circulation type refractory material regeneration furnace with multiple preheating effects. Background Art

[0002] A regeneration furnace is a device for recycling materials such as scrap iron or waste activated carbon. Its working principle is to remove pollutants or impurities in the materials through high-temperature treatment and restore their original properties, thereby realizing the recycling of resources. It is a widely used heating device in industry for high-temperature treatment of materials to achieve the regeneration or pyrolysis of materials;

[0003] In the existing thermal circulation type refractory material regeneration furnace, directly performing high-temperature treatment on the materials will greatly reduce the drying efficiency and quality of the materials. For example, the utility model patent with the authorization announcement number CN219829491U discloses an energy-saving regeneration furnace, including: a hearth furnace, a support column is fixedly installed at the bottom of the hearth furnace, a burning device is arranged in the hearth furnace for burning the materials, a heat exchange furnace is arranged on one side of the hearth furnace, and the heat exchange furnace is used as a cooling body to receive the materials burned in the hearth furnace. The heat exchange furnace transfers the heat energy in the burned materials to the hearth furnace to heat the materials. A preheating furnace is arranged at the top of the hearth furnace. The waste gas after burning in the hearth furnace passes through the heat exchange furnace and is transported by the heat exchange furnace to the preheating furnace to preheat the materials. In this energy-saving regeneration furnace, the burned materials enter the heat exchange furnace and accumulate. The heat exchange furnace exchanges heat with the accumulated materials, the heat exchange furnace recovers the heat energy in the materials and transfers the recovered heat energy to the hearth furnace through air flow to participate in burning. The heat exchange furnace transports the high-temperature waste gas generated in the hearth furnace to the preheating furnace, so that the materials are preheated before being burned in the hearth furnace, thereby reducing the fuel energy used for burning. However, in this device, by directly performing high-temperature burning on the materials entering the equipment without agitating the materials, the phenomenon of uneven heating of the materials will occur. In addition, directly feeding the materials will cause problems such as material accumulation and blockage. Therefore, we propose a thermal circulation type refractory material regeneration furnace with multiple preheating effects to facilitate solving the problems mentioned above.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figures 1-9 , the present invention provides a technical solution:

[0037] Embodiment 1: To solve the problems existing in the prior art, in this embodiment, through the following technical solutions, a thermal cycling refractory material regenerator with multiple preheating effects is provided with a support base 1; a multiple preheating mechanism is arranged above the left side of the support base 1, which can preheat the material multiple times before high-temperature heating, thereby improving the heating efficiency and quality of the material; a stirring mechanism is arranged inside the equipment body 25, which can fully stir the material inside the equipment body 25, so that the material can be uniformly heated at high temperature, and an anti-feeding blockage mechanism is arranged inside the third preheating box 17, which can transfer the material into the equipment body 25 in small amounts multiple times, effectively avoiding the situation of blockage and accumulation when feeding the material; first, an electric heating wire is arranged on the inner wall of the equipment body 25. When the electric heating wire is turned on, the inside of the equipment body 25 can be heated. Since an air suction pipe 34 is arranged above the inside of the first preheating box 2 from the inside of the equipment body 25, and a heat transfer pipe 35 is connected to the rear side of the air suction pipe 34, that is, the air suction pipe 34 can absorb the heat inside the equipment body 25 through the air suction pipe 34, and the heat transfer pipe 35 transfers the heat into the inside of the first preheating box 2, the second preheating box 9 and the third preheating box 17 respectively. The material is poured into the inside of the first preheating box 2 from the middle feeding port 3 of the first preheating box 2. Three ventilation pipes 4 are arranged above the first preheating box 2 for ventilation, and the temperature inside the first preheating box 2 can be adjusted. That is, when the material enters the inside of the feeding port 3, the motor 6 connected to the front side of the screw rod 5 can be turned on, so that the screw rod 5 rotates inside the first preheating box 2, and the material can be scattered, so that it can be uniformly preheated inside the first preheating box 2. After preheating, it can enter the inside of the transfer pipe 8 along the slope of the guide plate 7 arranged below the inside of the first preheating box 2. Open the valve inside the transfer pipe 8 so that the preheated material inside the first preheating box 2 enters the inside of the second preheating box 9. At this time, turn on the motor 6 connected to the top of the stirring rod 15 arranged inside the second preheating box 9, so that the stirring rod 15 slides inside the sliding groove 14 installed above the rack 13. That is, when the stirring rod 15 slides inside the sliding groove 14, it can push the rack 13 to move inside the fixed frame 10, and the first gear 16 meshing with the rack 13 will rotate, driving the other rack 13 to move inside the fixed frame 10. Since a sliding column 11 is installed below the rack 13 and a pushing plate 12 is installed below the sliding column 11, the pushing plate 12 can move left and right inside the second preheating box 9, and the material entering the second preheating box 9 can be stirred to preheat it again. At the same time, two ventilation pipes 4 are also arranged on the front and rear sides inside the second preheating box 9 to adjust the temperature inside the second preheating box 9. That is, when the material is preheated for the second time, a sieve plate 20 is arranged below the middle of the second preheating box 9. The electric telescopic rod 19 connected to the outside of the sieve plate 20 can be turned on, so that the sieve plate 20 moves outward, and the material inside the second preheating box 9 can enter the inside of the third preheating box 17.First, it will enter the inside of the movable plate 18 installed above the inside of the third preheating box 17. A plurality of holes are arranged in an array inside the movable plate 18, that is, the material can be evenly fed into the inside of the third preheating box 17. The third preheating box 17 can perform the third preheating on the material. At the same time, a ventilation pipe 4 is arranged on the front side of the third preheating box 17. The temperature settings inside the first preheating box 2, the second preheating box 9, and the third preheating box 17 are gradually increased. That is, after the material is preheated three times, a cover plate 22 is arranged below the middle of the third preheating box 17, and the cover plate 22 is arranged above the feeding pipe 21 connected to the lower part of the middle of the third preheating box 17. That is, a connecting shaft 23 is fixedly connected inside the cover plate 22. The motor 6 connected to the front end of the connecting shaft 23 can be turned on, so that the connecting shaft 23 can drive the cover plate 22 to rotate repeatedly inside the third preheating box 17, and the material inside the third preheating box 17 can enter the inside of the feeding pipe 21 below the cover plate 22 in small amounts multiple times. Since the right upper side of the feeding pipe 21 is connected to the equipment body 25, the suction pump 24 arranged in the middle of the feeding pipe 21 can be turned on, and the material can be transported into the inside of the equipment body 25 in small amounts multiple times. At this time, the motor 6 arranged above the middle of the equipment body 25 is turned on. Since the connecting rod 29 is fixedly installed on the outside of the motor 6, and the second gear 27 is installed below the connecting rod 29, when the motor 6 is started, the connecting rod 29 can drive the second gear 27 to rotate together. When the second gear 27 rotates, it can be meshed with the rack ring 26, and the stirring rod 28 installed in the middle of the second gear 27 can stir the material inside the equipment body 25. In addition, a hydraulic rod 30 is installed on the output shaft of the motor 6, and a moving ring 31 is installed at the output end of the hydraulic rod 30. That is, when the hydraulic rod 30 is turned on, the output end of the hydraulic rod 30 can push the moving ring 31 to move up and down in the middle of the equipment body 25. The settings of the moving ring 31 and the stirring rod 28 can stir the material sufficiently, so that the material can be heated evenly at a high temperature. That is, after the material is heated, it can enter the inside of the aggregate tank 32 arranged below the equipment body 25 for unified collection. A purification pipe 33 is installed at the rear side of the aggregate tank 32, and the purification pipe 33 can absorb and purify the waste gas generated by heating the material, and can avoid the situation that workers accidentally inhale it.,

[0038] In the existing regeneration furnace, due to insufficient preheating of the material, the efficiency and quality of material drying will be greatly reduced, such as Figure 1 、 Figure 3 and Figure 4As shown in the figure, the multiple preheating mechanism includes a first preheating box 2 arranged above the left side of the support base 1. A second preheating box 9 is installed below the first preheating box 2, and a third preheating box 17 is fixedly installed below the second preheating box 9. That is, when the material enters the first preheating box 2 from the feed inlet 3, the first preheating can be carried out. After being preheated in the first preheating box 2, it will enter the second preheating box 9 by opening the valve inside the transfer pipe 8 for the second preheating. After being preheated inside the second preheating box 9, the electric telescopic rod 19 is opened, so that the output end of the electric telescopic rod 19 pulls the moving plate 18 to move outward, thereby enabling the material to enter the third preheating box 17 for the third preheating. The temperature settings inside the first preheating box 2, the second preheating box 9, and the third preheating box 17 increase gradually. That is, multiple preheating can improve the efficiency and quality of material drying.

[0039] Embodiment 2: In the existing regeneration furnace, when the material is heated, there is no stirring device, which will cause uneven heating of the material. For example Figure 5 , Figure 7 and Figure 9 As shown in the figure, the stirring mechanism includes a rack ring 26 arranged above the inside of the equipment body 25. A second gear 27 is meshed and connected inside the rack ring 26. A stirring rod 28 is fixedly installed inside the second gear 27. At the same time, a connecting rod 29 is installed above the second gear 27. The inner side of the connecting rod 29 is fixedly connected to the output shaft of the motor 6. That is, when the motor 6 is turned on, the connecting rod 29 can be rotated. That is, the connecting rod 29 can drive the second gear 27 to engage and rotate with the rack ring 26. At this time, the stirring rod 28 installed in the middle of the second gear 27 can fully stir the material inside the equipment body 25. At the same time, the output shaft of the motor 6 arranged above the middle of the equipment body 25 is installed with a hydraulic rod 30. The output end of the hydraulic rod 30 is installed with a moving ring 31. That is, when the hydraulic rod 30 is turned on, the output end of the hydraulic rod 30 can push the connected moving ring 31 to move up and down in the middle of the equipment body 25. Under the action of the motor 6, the moving ring 31 will also rotate. That is, the settings of the moving ring 31 and the stirring rod 28 can fully stir the material and make it heated evenly.

[0040] Embodiment 3: In the existing regeneration furnace, when the material is poured in at one time, it will cause problems such as material accumulation and blockage. For example Figure 1 , Figure 4 and Figure 5As shown in the figure, the anti-feeding blockage mechanism includes a feeding pipe 21 connected to the lower part of the third preheating box 17. The upper right side of the feeding pipe 21 is connected to the equipment body 25. At the same time, a cover plate 22 is arranged above the left side of the feeding pipe 21. A connecting shaft 23 is fixedly installed inside the cover plate 22, and the front end of the connecting shaft 23 is connected to a motor 6. Then, the motor 6 can be turned on. The motor 6 can make the cover plate 22 drive the connected connecting shaft 23 to rotate. When the connecting shaft 23 rotates, the materials inside the third preheating box 17 can enter the inside of the feeding pipe 21 below the connecting shaft 23. At this time, the suction pump 24 installed in the middle of the feeding pipe 21 is turned on, that is, the suction pump 24 is turned on. The connecting shaft 23 can rotate back and forth to open and close, and can enter the inside of the equipment body 25 through the feeding pipe 21 in small amounts multiple times.

[0041] This is the entire working process of a thermal cycle type refractory material regeneration furnace with multiple preheating effects. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
