Description

Technical Field

[0001] The utility model relates to the technical field of sintering trolley side plates, in particular to a side plate for a sintering trolley with air leakage prevention. Background Technique

[0002] The sintering trolley is the main operating component of the sintering machine. Its main function is to form a running rotary chain between the head and tail wheels of the sintering machine. On the upper horizontal section, it receives the sintering mixture. After preheating, ignition, sintering, cooling, and material turning, it returns to the head wheel during the return journey to form a drive cycle to achieve the purpose of sintering the material. The sintering trolley is composed of a trolley body, wheels, a sealing mechanism, grate bars, side plates, and heat insulation pads. The sealing mechanism is installed on the side plates, and the side plates are vulnerable parts on the trolley and important components affecting the air leakage rate. The quality of the side plate structure directly affects its own service life and thus affects the maintenance cost.

[0003] The existing Chinese patent document CN201020263521.3 discloses a sintering trolley side plate, which relates to the technical field of sintering trolleys in the metallurgical industry. It includes at least two side plates, and mutually cooperating convex platforms and grooves are provided between adjacent two side plates. A rabbet formed by a pair of convex platforms and grooves is provided at the relative position where the two side plates are joined. In this way, the rabbet can play an auxiliary positioning role during the assembly of the side plates, improving the assembly efficiency of workers. During use, the existence of the rabbet limits the deformation direction of the side plate and reduces the deformation tendency. At the same time, since the flat joint surface is changed into a curved joint surface, this increases the air leakage resistance and reduces the air leakage volume. Even if the side plate has a small amount of deformation, due to the existence of the rabbet, the situation of material leakage can be avoided. The use of the new side plate greatly improves the service life of the side plate and improves the production efficiency.

[0004] However, there are certain defects in the above patent during use. A rabbet formed by a pair of convex platforms and grooves is provided. Since there is no mutual engagement between the convex platforms and grooves forming the rabbet, its sealing degree and connection strength have not been greatly changed, which is prone to air leakage, and under multiple impacts, it will cause the side plate to deform and break.

[0005] Therefore, a side plate for a sintering trolley with air leakage prevention is proposed here to solve the above problems. Content of the Utility Model

When the upper railing plate 1 is fixedly connected to the lower railing plate 2, the guiding block 15 is engaged in the installation groove 21; and a heat-insulating cotton is provided at the bottom of the guiding block 15. The cooperation between the guiding block 15 and the installation groove 21 effectively prevents wind from leaking through the gaps between the railing plates, improves the sintering efficiency and reduces the energy consumption.

[0031] A plurality of installation holes 16 are provided on the back surfaces of the guiding block 15 and the clamping groove. The installation holes 16 are arranged evenly at equal distances. A stud 4 is provided in the installation hole 16, and the stud 4 tightly fixes and connects the upper railing plate 1 and the lower railing plate 2.

[0032] A buffer platform 5 is provided on the back surface of the lower railing plate 2. The buffer platform 5 is fixed to the upper end of the back surface of the lower railing plate 2. A plurality of placing holes 51 are provided on the buffer platform 5. A support column 3 is provided in the placing hole 51.

Under the guidance of the guiding block 15, slowly push the upper railing plate 1 from the side towards the installation groove 21 until the guiding block 15 is completely engaged in the installation groove 21 to achieve preliminary positioning;

[0039] On the back of the guiding block 15 and the installation groove 21, find the evenly spaced installation holes 16. Pass the stud 4 through the installation holes 16, and use tools such as nuts or bolts to tighten the stud 4, thereby tightly fixing and connecting the upper railing plate 1 and the lower railing plate 2 together to complete the installation operation.
