Description

Technical Field

[0001] The utility model relates to the technical field of sintering equipment, in particular to a single-roller material receiving trough. Background Art

[0002] The sintered sintered cakes are directly unloaded from the trolley at the tail end of the sintering machine into the single-roller receiving trough. The receiving trough is subjected to huge impact and wear, which requires the receiving trough to have sufficient strength and wear resistance.

[0003] The single roller receiving trough currently used is designed with a slot-fixed wear-resistant block on the material-facing surface, which is used to withstand the impact wear of high-temperature sintered cakes. However, there are many problems during use, which affect normal production. The main problems are: (1) When this type of wear-resistant block is installed, a section of it is suspended outside the guide trough body, such as Figure 1 As shown, and as Figure 2 As shown in the figure, there is a slot in the middle of the wear-resistant block, which is used to cooperate with the slot baffle. The strength of the slot is the worst. Under the huge impact force of the sintered cake, the wear-resistant block hanging outside the trough body is easy to break at the slot, causing damage to the crushing roller teeth of the single roller and bending of the water-cooled grate plate, seriously affecting production. ⑵ It is very difficult to disassemble and repair the wear-resistant block, which takes a long time and has high labor intensity. ⑶ When the wear-resistant block on the facing surface is used, one section is suspended outside the bottom plate of the receiving trough. If the supporting rib plate is burned, the bottom plate of the receiving trough will bend and deform due to insufficient support strength, and the wear-resistant block will tilt forward. When the sintered ore is smashed down, the downward-inclined wear-resistant block will not only bear the impact load, but also be subject to a large bending moment force and is easy to break. Summary of the invention

[0004] In view of the above problems, the purpose of the utility model is to provide a single-roller material receiving trough.

[0005] The technical solution adopted by the utility model is as follows:

[0006] The utility model proposes a single-roller material receiving trough, comprising a material receiving trough body, wherein a wear-resistant block is fixedly connected to the upper surface of the front side of the bottom plate of the material receiving trough body; the wear-resistant block is an overall rectangular structure, and a pin hole is provided on the rear end face thereof, and is fixedly connected to the material receiving trough body by a fixing pin; an inwardly recessed groove structure is provided between the lower side of the front end face of the wear-resistant block and the right side of the lower end face.

[0007] Furthermore, a heat-resistant casting plate is provided at the front end of the bottom plate of the receiving trough body.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] The utility model can not only significantly increase the service life of the receiving trough and prevent the breakage accident of the wear-resistant block during the production process, but also facilitate replacement during maintenance and significantly reduce labor intensity.

[0015] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0016] It should be noted that, in the description of the present invention, the terms "upper", "lower", "top", "bottom", "one side", "the other side", "left", "right", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not mean that the device or element must have a specific orientation, be constructed and operated in a specific orientation.

[0017] See attached Figure 3-4 , gives the specific structure of an embodiment of a single-roller material receiving trough proposed by the utility model. The material receiving trough includes a material receiving trough body 5, and a wear-resistant block 3 is fixedly connected to the upper surface of the front side of the bottom plate 51 of the material receiving trough body 5; in this embodiment, the wear-resistant block 3 is a rectangular parallelepiped structure as a whole, and a pin hole 31 is opened in the middle area of ​​the rear side end face of the wear-resistant block 3, which is fixedly connected to the material receiving trough body 5 through a fixing pin 1, and an inwardly recessed groove structure 32 is set between the lower side of the front side end face of the wear-resistant block 3 and the right side of the lower end face; a positioning block 53 is fixedly connected to the portion of the upper end face of the front side of the bottom plate 51 corresponding to the groove structure 32.

[0018] In this embodiment, a detachable heat-resistant casting plate 52 is further provided at the front end of the bottom plate 51 of the receiving trough body 5 to protect the bottom plate 51 from being burned.

[0019] The utility model improves the structure and fixing method of the wear block on the material receiving trough, cancels the overhanging part of the head of the wear block and the slot fixing structure, and changes it into a concave form at the bottom. The concave step abuts against the positioning block 53 on the end face of the trough, which can not only effectively fix but also facilitate disassembly and assembly. At the same time, a detachable heat-insulating casting plate 52 is added to the front end of the supporting bottom plate 51 to protect the bottom plate 51 from being burned.
