Description

Technical Field

[0001] The utility model relates to the technical field of plasma vaporization furnaces, in particular to a plasma vaporization furnace suitable for composite re-sintered bricks. Background Art

[0002] Composite re-sintered brick is a material usually used for high-temperature industrial kilns and furnace wall linings. It has good refractoriness and thermal stability. However, the traditional preparation process of composite re-sintered brick has problems such as incomplete mineral crystallization and insufficient thermal stability, which affect its performance and service life. In recent years, plasma vaporization technology has received widespread attention as a high-efficiency surface treatment process. By converting the material into plasma and then depositing it onto the surface of the substrate, surface modification, coating preparation and other functions can be achieved. Therefore, the application of plasma vaporization technology to the preparation process of composite re-sintered brick is expected to improve its performance and quality.

[0003] In the actual use of plasma gasification furnace, its usual operating method is to add fly ash and bottom ash into the same hopper simultaneously. When faced with a huge feed volume, it is impossible to achieve comprehensive and thorough mixing of fly ash and bottom ash, resulting in the fly ash and bottom ash entering the furnace often still being separated from each other. This undoubtedly imposes obvious limitations on plasma gasification furnaces in the field of composite re-sintered bricks, making it difficult for them to fully exert their due performance and advantages.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A plasma gasification furnace suitable for composite re-sintered bricks includes a furnace body, a side wall of the furnace body is connected to a feeding frame, an end of the feeding frame away from the furnace body is connected to an auger mechanism, one end of the auger mechanism is connected to a frame, the frame is composed of a cylindrical box body and a trumpet-shaped box body, the top of the cylindrical box body is provided with a plurality of groups of through grooves in a circular array, the inner walls of the through grooves are fixedly connected to through pipes, a hopper is provided on the top of the frame body, the inner side wall of the hopper is fixedly connected to a partition, the bottom of the hopper is connected to a plurality of groups of feeding pipes one and a plurality of groups of feeding pipes two, the feeding pipes one and the plurality of groups of feeding pipes two are respectively connected to corresponding through pipes.

[0008] Furthermore, the interior of the cylindrical box is movably connected to a rotating shaft via a bearing, a rotating sleeve is fixedly sleeved on the outer side of the rotating shaft, and a plurality of rotating plates are fixedly connected to the side wall of the rotating sleeve in a circular array.

[0009] Furthermore, a plurality of frame rods are fixedly connected to the bottom end of the rotating plate, and the cross-section of the frame rods is triangular, and a motor for driving the rotating shaft to rotate is fixedly installed on the top of the cylindrical box.

[0010] Furthermore, a plurality of groups of support rods are fixedly connected to the inner wall of the trumpet-shaped box, an organic cover shell is arranged inside the trumpet-shaped box, the outer wall of the cover shell is fixedly connected to the ends of the support rods, bevel gear one, bevel gear two and bevel gear three are movably connected to the inside of the cover shell through bearings, and bevel gear two is meshingly connected with bevel gear one and bevel gear three.

[0011] Furthermore, the bevel gear one is fixedly connected to the bottom end of the rotating shaft, a rotating rod is arranged below the machine cover shell, the top end of the rotating rod is fixedly connected to the bevel gear three, and the side wall of the rotating rod is fixedly connected with multiple groups of stirring rods in a circular array.

[0012] Furthermore, the cylindrical box is located on the top of the horn-shaped box, and the cylindrical box is communicated with the horn-shaped box.

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

[0014] A plurality of partitions are fixed on the inner wall of the hopper, and the partitions reasonably divide the hopper so that it can implement pre-intervention operations on two or more types of materials, thereby realizing pre-partitioned and interval feeding of these materials, which greatly reduces the difficulty coefficient of subsequent material mixing. The frame rod is inclined relative to the rotating plate, and the cross-sectional shape of the frame rod is triangular, which enables the frame rod to effectively guide the fly ash and slag to be discharged in an oblique downward direction, which not only prolongs the residence time of the fly ash and slag in the cylindrical box, but also significantly improves the dispersion degree of the material. Combined with the rotating rod with the opposite rotation direction, the mixing degree of the material is further improved, which can effectively avoid the situation where the materials entering the plasma gasification furnace are still unevenly mixed, thereby preventing the problem of affecting the subsequent processing effect due to uneven material mixing.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1: Figure 1 - Figure 5 As shown, a plasma gasification furnace suitable for composite re-sintered bricks includes a furnace body 1, a side wall of the furnace body 1 is connected to a feed frame 2, an end of the feed frame 2 away from the furnace body 1 is connected to an auger mechanism 3, and one end of the auger mechanism 3 is connected to a frame 4. It should be noted that the auger mechanism 3 is an existing device, and its function is to use spiral blades to spirally transport materials into the furnace body 1. The frame 4 is composed of a cylindrical box 401 and a trumpet-shaped box 402. The cylindrical box 401 is located at the trumpet. shaped box body 402, and the cylindrical box body 401 is connected with the trumpet-shaped box body 402, the top of the cylindrical box body 401 is provided with a plurality of groups of through grooves in a circular array, the inner wall of the through groove is fixedly connected with a through pipe 5, the top of the frame body 4 is provided with a hopper 6, the inner wall of the hopper 6 is fixedly connected with a partition 7, the bottom of the hopper 6 is connected with a plurality of groups of discharge pipes 801 and a plurality of groups of discharge pipes 802, and the discharge pipes 801 and the plurality of groups of discharge pipes 802 are respectively connected with the corresponding through pipes 5.

[0024] The interior of the cylindrical box 401 is movably connected to a rotating shaft 9 through a bearing, and a rotating sleeve 10 is fixedly mounted on the outer side of the rotating shaft 9. The side walls of the rotating sleeve 10 are fixedly connected to multiple sets of rotating plates 11 in a circular array, and the bottom ends of the rotating plates 11 are fixedly connected to multiple sets of frame rods 12, and the cross-section of the frame rods 12 is triangular. A motor 13 for driving the rotating shaft 9 to rotate is fixedly installed on the top of the cylindrical box 401.

[0025] like Figure 2 As shown, a plurality of partitions 7 are fixedly connected to the top of the hopper 6, and the partitions 7 cooperate with the inner wall of the hopper 6 to divide the space inside the hopper 6. When specifically set, the fly ash and the slag are continuously fed into the interval formed by the partitions 7 and the inner wall of the hopper 6 at intervals, and two or more materials are pre-intervened in the feeding process, so that they are pre-divided and fed at intervals, thereby greatly reducing the difficulty of subsequent material mixing;

[0026] The fly ash and slag enter the cylindrical box 401 through the discharge pipe 1 801 and the discharge pipe 2 802 and the corresponding through pipe 5. At this time, the motor 13 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the rotating plate 11 and the frame rod 12 to rotate synchronously through the rotating sleeve 10. The number of rotating plates 11 is consistent with the number of intervals formed by the partition 7 and the inner wall of the hopper 6. When the rotating plate 11 rotates at a high speed, the fly ash and slag discharged at intervals can be preliminarily mixed;

[0027] When the frame rod 12 is rotating, the frame rod 12 is inclined relative to the rotating plate 11, so that the frame rod 12 guides the fly ash and slag to be discharged in an oblique downward direction, on the one hand, the retention time of the fly ash and slag in the cylindrical box 401 is prolonged, and the fly ash and slag are fully mixed, and on the other hand, the cross section of the frame rod 12 is triangular, and the frame rod 12 with a triangular cross section can perform deep dispersion and discharge of the fly ash and slag in the process of being discharged, so that the fly ash and slag retained in the cylindrical box 401 are mixed more evenly;

[0029] During the specific setting, the rotating shaft 9 drives the bevel gear 1 161 to rotate during the rotation process, and the bevel gear 1 161 drives the bevel gear 3 163 to rotate through the bevel gear 2 162, and the bevel gear 3 163 drives the rotating rod 17 to rotate in the opposite direction. The rotating rod 17 rotates in the opposite direction relative to the rotating plate 11 and the frame rod 12. The cross-section of the rotating rod 17 is also triangular, and the rotating rod 17 rotates relatively in the opposite direction, thereby deeply mixing the fly ash and the slag. The fly ash and slag that have been mixed for the second time have a high degree of mixing at this time. Then, after entering the interior of the auger mechanism 3, the spiral blades in the auger mechanism 3 spirally convey the material, and enter the furnace body 1 through the unloading frame 2 for further processing.
