Description

Technical Field

[0001] The utility model relates to a tamping hammer rod device capable of adjusting the tamping density of coal cakes, belonging to the technical field of coal coking. Background Art

[0002] The tamping hammer is a coal coking equipment, which is mainly used to tamp the prepared loose coal into coal cakes of different densities for coking. For the coking oven operation process, it is the coal cake tamping process.

[0003] Modern horizontal chamber tamping coke ovens all use external briquette tamping, which is divided into vertical briquette tamping and horizontal briquette tamping. The so-called vertical and horizontal briquette tamping refer to the shape of the briquette placement. Vertical briquette tamping means that the height of the briquette placed on the coal support plate is much larger than the width, and horizontal briquette tamping means that the width of the briquette placed on the coal support plate is larger than the height. After the loose coal is tamped into briquette, the briquette needs to be loaded into the coke oven for the coking process to finally obtain qualified coke.

[0004] The ramming coking plant needs to produce coke of different strength and reactivity according to the different requirements of users. Therefore, during the ramming and forming process of coal cakes, it is also necessary to adjust the density of coal cakes in time from 0.8t / m3 to 1.1t / m3 (dry basis).

[0005] Since the existing tamping machine is a fixed-stroke lifting mechanism, the tamping work is determined and cannot be changed, so it is difficult to adjust the density of coal cakes; part of the existing horizontal tamping machine adopts a hammer mechanism, which is as difficult to control the density of coal cakes as the vertical tamping machine, and part of it adopts a hydraulic mechanism, which has a low coal cake forming density, a long operating time and low efficiency.

[0006] Therefore, designing a tamping hammer rod device that can adjust the tamping work and the density of coal cakes at any time is in line with the actual production needs of enterprises.

[0007] In view of the above problems, a tamping hammer device with adjustable coal cake density is designed. Utility Model Content

[0012] Preferably, the flexible hammer lifting rope is a steel wire rope or a ring chain.

[0014] Compared with the prior art, the utility model has the following technical effects: the utility model adopts a two-stage adjustment structure, and the height of the tamping hammer rod is adjusted by a lifting mechanism. At the same time, the tamping hammer rod can also be adjusted for a second time by a hammer lifting cylinder. In this way, the height of the tamping hammer rod can be accurately adjusted according to actual needs, and then the loose coal in the coal cake mold can be tamped into coal cakes of a certain density. The operation is simple and the use is convenient, which greatly improves the flexibility and convenience of tamping, and can also overcome the problems of low efficiency and insufficient density of existing hydraulic coal cake machines.
