Technical Field
The utility model relates to an ferroalloy smelting equipment technical field particularly, especially relates to a ferroalloy pelletizing shaft furnace turning module.
Background
The 'ferroalloy pellet shaft furnace' is the necessary equipment in the process of producing ferroalloy by an oxidation pelletizing method, and the corner module is an important part of an inner cylindrical sleeve of the shaft furnace. After the shaft furnace storage platform, the outer cylindrical sleeve and the inner cylindrical sleeve are filled with the ferroalloy green pellets, the storage platform can drive the outer cylindrical sleeve and the inner cylindrical sleeve to rotate together under the action of friction force. The inner cylindrical sleeve corner module now directly contacts the iron alloy pellets. The iron alloy pellets rub against the corner modules. The temperature for pellet firing is above 1100 ℃, while the material of the traditional corner module is ZG40Ni35Cr26Si2, and the heat-resisting temperature is 1200 ℃. Therefore, the phenomena of corner module abrasion, thermal deformation, burning off and the like frequently occur in the production process. Resulting in a low service life of the corner modules, which need to be replaced in about 3 months. The traditional corner module is spliced by a plurality of blocks, and a single module needs to firstly apply an upward pretightening force obliquely along the circumference to the module in a double-pull-rod compression spring mode and then fixedly matched with the inner cylindrical sleeve by using bolts. Because the amount of spring compression needs to be adjusted continuously during installation, replacement of spare parts is extremely inconvenient. The long installation adjustment time is a problem of the corner module. And is also a key factor for restricting the production capacity of the pellet shaft furnace.

As shown in fig. 1-5, the utility model provides a ferroalloy pelletizing shaft furnace turning module, includes: corner module bodies-male 1, middle corner module body 2 and corner module body-female 3;
the three modules can form a corner module, namely a male end and a female end joint are spliced in sequence, and finally a middle corner module body is installed to be spliced into a whole circle;
splicing a plurality of corner modules to finally form an annular structure;
the corner module bodies-male 1, middle corner module body 2 and corner module body-female 3 all comprise: a corner part 5 with an inner surface being a circular arc surface, an axial extension part extending upwards along the upper edge of the corner part 5 and a radial extension part extending horizontally along the lower horizontal edge of the corner part 5;

the radial extension part is provided with a bolt long hole 6;
the axial extension part is provided with a bolt hole 5;
the bolt long hole 6 is a strip-shaped hole.
Further, in the above-mentioned case,
the position of the radial extension part where the bolt long hole 6 is arranged is a boss structure.
Further, in the above-mentioned case,
the position of the axial extension part provided with the bolt hole 5 is of a boss structure.
The corner modules are formed by splicing the three corner modules, wherein each corner module is more than 1. Compared with the traditional corner module structure, the angle of the novel corner module body is increased, and the whole quantity is reduced. Because the whole block number is reduced, the butt joint times between the modules are reduced during installation, and the installation and disassembly time is saved.
The corner 5 part of the corner module body is directly contacted with the ball, the two parts rub with each other, the corner is seriously abraded after long-time work, and the service life of the corner module is determined by the part. The corner 5 is formed by integrally and solidly pouring the corner part to form a round angle. The thickness of the corner is increased by the structural form, and the problem of stress concentration during processing and manufacturing is solved. The corners are solid structures without tie rod holes. The spring compression amount needs to be continuously adjusted when the traditional corner module is installed, so that the difficulty in installing and disassembling the corner module body is high. The novel corner module has no pull rod spring, and the structure not only increases the strength of the corner part of the corner module body, but also reduces the difficulty of installation and disassembly.
The angle of the corner module body is increased, the number of the corresponding bolt holes 4 is increased, the bolt holes are uniformly distributed along the radial direction of the module at an angle of 24 degrees and are spliced into a whole circle. But is not limited to 24 deg., and any even angle is evenly divided by 360 deg. of circumference. The corner modules-the male corner module and the corner module-the female corner module are respectively overlapped in sequence, and finally the middle corner module body is overlapped. Wherein the corner module-male 7, corner module-female 7, middle corner module body 1, 15 in total. Traditional turning module body construction bolt position and turning module body wall thickness uniform thickness, novel turning module body bolt has increased certain thickness to the part of closing, has promoted holistic intensity.
All bolt holes of the traditional corner module body are round holes, and the amount of thermal deformation is not reserved. During operation, the fixing bolt is subjected to shearing force, and the bolt is sheared after long-time operation. The novel corner module bolt slot hole 6 is a long strip shape (strip-shaped hole) of an arc line. The advantages of this shape are: when the module is deformed by heating, the main deformation direction is the circumferential tangential direction. When the module is deformed along the tangential direction, because the bolt long hole 6 is a long hole, a certain amount of expansion and contraction is provided, the fixing bolt is not subjected to shearing action force, and the possibility that the bolt is cut off is reduced. The phenomenon of falling off of corner modules is solved from the installation design; and the bolt is installed in a sliding manner during installation, so that the problem that the corner module and the bolt hole at the bottom of the inner cylindrical sleeve cannot be aligned is solved.
The corner module body is made of ZGCr28Ni48W 5. The heat-resistant temperature of the material reaches 1400 ℃, and compared with ZG40Ni35Cr26Si2, the material is more wear-resistant, corrosion-resistant and heat deformation-resistant.
