Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical engineering equipment, and particularly relates to a furnace kiln support water beam. Background Art

[0002] The furnace kiln support water beam is a structure installed above the cooling zone in the vertical furnace to support and stabilize the air guiding wall. During the normal production of the vertical furnace, a strong high-temperature, high-pressure dust gas flow will be generated inside the vertical furnace, which will cause wear on the inner side of the ventilation holes of the furnace kiln support water beam and the bottom water beam pipes, resulting in the rupture and leakage of the bottom of the boiler pipes on the inner side of the ventilation holes of the water beam, the deformation and bending of the water beam, the displacement of the air guiding wall, and even collapse, seriously affecting the later pellet output and quality.

[0003] Therefore, it is necessary to design a furnace kiln support water beam, improve the structure of the furnace kiln support water beam, enhance the wear resistance of the easily worn parts, strengthen the structural stability, synchronize the service life of the water beam and the air guiding wall, extend the service life of the air guiding wall, maximize the equipment use efficiency, and thus reduce the production cost. Summary of the Utility Model

[0004] Aiming at the problems of the prior art, the purpose of the utility model is to provide a furnace kiln support water beam to solve the problems of wear on the inner side of the ventilation holes of the furnace kiln support water beam and the bottom water beam pipes, resulting in the rupture and leakage of the bottom of the boiler pipes on the inner side of the ventilation holes of the water beam, the deformation and bending of the water beam, the displacement of the air guiding wall, and even collapse.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A furnace kiln support water beam includes two groups of water beam pipes, the two groups of water beam pipes are arranged relatively parallel, a diversion hole is arranged between the two groups of water beam pipes, a plurality of partition plates are arranged between the two groups of water beam pipes, a flow equalizing hole is arranged in the middle of the partition plates, a stainless steel protection plate is arranged inside the water beam pipes, and a semi-circular alloy patch tile is arranged at the bottom of the water beam pipes.

[0007] More preferably, the edge of the partition plate matches the stainless steel protection plate inside the water beam pipe.

[0008] More preferably, the upper and lower sides of the flow equalizing hole are arranged as semi-circles.

[0009] More preferably, two positioning steels are arranged between every two water beam pipes.

[0010] More preferably, 2 shrinkage holes are opened at the bottom of the semi-circular alloy patch tile.

[0011] The utility model has the following beneficial effects compared with the prior art:

[0012] 1. A kind of furnace support water beam provided by the utility model does not change the material of the water beam pipe body, extends the internal partition plate of the furnace support water beam, and sets flow equalizing holes in the partition plate, which can improve the flow-through and flow-stabilizing effects of the water beam, not only can enhance the stability of drying and cooling in the furnace, but also can avoid the serious local wear inside the water beam. Therefore, the processing difficulty and cost increase little, and the improvement in production capacity after improvement can be ignored.

[0013] 2. The cooling air in the furnace of this utility model is from bottom to top, which causes the most serious wear at the bottom of the water beam pipe. Lining wear-resistant alloy tiles on the bottom water pipe of the water beam can effectively slow down the wear of the bottom water pipe and strengthen the stability of the water beam body structure at the same time.

[0018] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present utility model. In addition, in the description of the present utility model, the meaning of "several" is two or more, unless otherwise specifically defined.

[0020] Such as Figures 1-3As shown, a furnace supporting water beam includes two groups of water beam pipes 1, which are arranged relatively parallel. Two positioning steels 6 are arranged between the two water beam pipes 1 for alignment and positioning when the pipes are connected. A guide hole 2 is arranged between the two groups of water beam pipes 1. The guide hole 2 is above the cold air pipe of the vertical furnace. When the cooling air goes up, the pellets above the water beam are cooled through the guide hole 2. A plurality of partitions 4 are arranged between the two groups of water beam pipes 1. The partitions 4 are evenly arranged at intervals of 580 mm. A flow-equalizing hole 5 is opened 150 mm above the bottom of the partition 4 to evenly distribute the airflow entering the air guide wall to avoid aggravation of local wear. The upper and lower sides of the flow-equalizing hole 5 are arranged in a semicircular shape with a semicircular aperture of 300 mm. The semicircular design can prevent the weld of the partition 4 from being cracked due to thermal expansion and contraction. A stainless steel protective plate 3 is provided on the inner side of the water beam pipe 1 to reduce the direct scouring of the side wall of the water beam pipe 1 by the airflow. The stainless steel protective plate 3 is welded and fixed to the water beam pipe 1. The weld is welded in sections. The partition 4 is welded and fixed to the stainless steel protective plate 3. The edge of the partition 4 matches the stainless steel protective plate 3 on the inner side of the water beam pipe 1 and is tightly connected, so that the partition 4 and the stainless steel protective plate 3 have good sealing properties. A semicircular alloy patching tile 7 with an inner diameter of 260mm, a wall thickness of 20mm, and a length of 400mm is provided at the bottom of the water beam pipe 1. The semicircular alloy patching tile 7 is evenly welded on the pipe wall at the bottom of the water beam pipe 1 at intervals of 15mm, which effectively reduces the wear of the dust airflow on the bottom water beam pipe 1, and also strengthens the stability of the water beam pipe structure. Two Φ50mm shrinkage holes 8 are opened at the bottom of the semicircular alloy patching tile 7 to prevent the weld of the semicircular alloy patching tile 7 from being cracked.

[0021] When the utility model is used, the cooling air duct in the furnace is below the water beam. When the cooling air goes up, dust airflow will be generated. The cooling air cools the pellets above the water beam through the guide hole 2 of the water beam. After the cooling air enters the guide hole 2, it is evenly distributed and diverted under the action of the equalizing hole 5 on the partition 4, so as to achieve the effect of uniform cooling of the pellets above the water beam, and at the same time reduce the local wear of the water beam pipe 1. When the dust airflow passes through the stainless steel protective plate 3, it effectively protects and isolates the water beam pipe 1, thereby reducing the wear of the dust airflow on the water beam pipe 1. The utility model improves the structure of the furnace water beam supporting the furnace, so that the wear resistance of the easily worn parts is improved, and the use cycle of the water beam and the air guide wall is synchronized, so as to maximize the equipment use efficiency and reduce production costs.

[0022] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
