Description

Technical Field

[0001] The utility model relates to the field of a mixing drum of a sintering machine, in particular to a lining plate structure of a mixing drum of a sintering machine. Background Art

[0002] The mixing drum of the sintering machine is a component of the sintering machine. It is mainly used to mix the iron ore powder and other additives evenly so that the mixture can be sintered better in the sintering machine. With the increase in the production capacity of the sintering machine, the filling rate of the existing mixing drum of the sintering machine has exceeded 18%. In order to ensure the pelletizing effect of the mixture, all-lime production is adopted. However, the high filling rate and all-lime production also increase the cohesiveness of the mixture. After being fed into the inlet side of the mixing drum of the sintering machine through the feeding conveyor belt, it is bound to cause sticking and ringing at the inlet. In order to avoid the above situation, a flexible movable liner is often set on the inlet side of the mixing drum of the sintering machine. The feeding conveyor belt feeds the material and falls on the movable liner. As the mixing drum of the sintering machine rotates, the movable liner keeps drooping, flipping and resetting to avoid the accumulation of the mixture and achieve a self-cleaning effect.

[0003] The utility model patent with publication number CN217844733U discloses a lining structure of a mixing drum of a sintering machine, including a fixed bushing fixed in the mixing drum of the sintering machine and a plurality of axial lifting strips evenly distributed along the circumferential direction of the cross section of the fixed bushing, a rubber lining is arranged between adjacent axial lifting strips, the rubber lining is arranged close to the inlet side of the mixing drum of the sintering machine and the side of the rubber lining away from the inlet of the mixing drum of the sintering machine is fixed on the fixed bushing, the rubber lining has a hollow inner cavity and a plurality of counterweight strips are fixed in the hollow inner cavity, the plurality of counterweight strips are evenly distributed along the axial direction of the mixing drum of the sintering machine; the counterweight strips thereon greatly increase the weight of the rubber lining while not affecting the bending of the rubber lining, which is beneficial for the rubber lining to reset and fit the inner wall of the fixed bushing when it is close to the bottom of the mixing drum of the sintering machine and for the rubber lining to droop, flip and dump the material when it is close to the top of the mixing drum of the sintering machine. However, the rubber lining has a certain lifespan and will age with the extension of use, which will affect its bending and reset effects. Therefore, it needs to be replaced regularly. The above-mentioned lining structure adopts multiple rubber linings, and the rubber lining is fixed to the fixed bushing between the two axial poplar strips with bolts. Each rubber lining requires at least four bolts to fix it. The large number of installation points makes the installation and disassembly speed slower. In addition, since the cross-section of the axial poplar strip is a trapezoidal structure, there is a gap between it and the edge of the rubber lining, which is easy to have material residue and requires secondary cleaning. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical problems and provide a lining plate structure of a mixing drum of a sintering machine.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a lining structure of a mixing drum of a sintering machine, comprising an inlet of a mixing drum of a sintering machine, a fixed bushing, a material strip, and a rubber lining. The fixed bushing is fixed in the inlet of the mixing drum of the sintering machine. There are multiple material strips, all of which are arranged on the inner side of the fixed bushing and are evenly distributed along the circumferential direction of the fixed bushing. A rubber lining is arranged between two adjacent material strips. A gap is arranged between the material strip and the fixed bushing. A connecting plate is arranged in the gap. The sides of two adjacent rubber linings close to each other are fixedly connected to the connecting plate. Multiple rubber linings form an annular structure through the connecting plate, and are sleeved on the inner side of the fixed bushing and the outer side of the material strip. Through hole one is arranged at both ends of the connecting plate. Through hole two and threaded hole groove are correspondingly arranged on the material strip and the fixed bushing, respectively. Bolts are arranged inside. The bolts pass through through hole two and through hole one in turn, and cooperate with the threaded hole groove to connect and fix the three.

[0006] Furthermore, a sink groove is provided on the inner side wall of the poplar material strip, the sink groove is coaxial with the second through hole, and the top of the bolt is located in the sink groove.

[0007] Furthermore, the connecting plate and the rubber lining plate are made of the same material and are integrally formed.

[0008] Furthermore, one end of the poplar material strip close to the interior of the mixing drum of the sintering machine is fixedly connected to a fixed bushing.

[0009] Furthermore, the thickness of the connecting plate is smaller than the thickness of the rubber lining, so that a limiting groove is formed inside between two adjacent rubber linings, and the width of the limiting groove matches the bottom width of the poplar strip.

[0010] Furthermore, the rubber lining is a hollow structure with a cavity formed inside.

[0011] Furthermore, a plurality of counterweights are provided inside the cavity of the rubber lining and are evenly distributed inside the rubber lining.

[0012] The advantages of the utility model compared with the prior art are: the utility model connects multiple rubber linings into a whole through a connecting plate, and when installing and fixing the rubber lining, it is only necessary to connect the two ends of the connecting plate with the poplar strip and the fixed bushing together through bolts, which greatly reduces the number of bolts, thereby realizing fast installation and disassembly, and the materials remaining in the gap between the rubber lining and the bottom edge of the poplar strip can be directly taken out when the rubber lining is disassembled, thereby eliminating the need for secondary cleaning.
