Detailed Description

As shown in figure 1 and figure 2, the utility model provides a chute device for a cold blast furnace slag crushing production line, which can effectively reduce the chute abrasion speed and prolong the chute service life. The chute device include chute body 1, the chute device still include material buffer structure 2, material buffer structure 2 set up on the inside wall in chute body 1 the place ahead. This application sets up material buffer structure 2 through increasing on current chute body 1's basis, and will material buffer structure 2 set up on the inside wall in chute body 1 the place ahead. Like this, when the drop, excessive all great, the granularity is inhomogeneous, and when getting into the chute body for the iron content material is high-speed, can carry out suitable buffering to the material through material buffer structure earlier, reduce its velocity of flow, avoid its direct and the inside wall of chute simultaneously, mainly be the preceding lateral wall direct contact who avoids material and 1 direct impact of chute body, reach the speed that reduces chute body self by quick wearing and tearing, and then realize extension chute life's purpose. Moreover, because what a large amount of, the material that lets out down at a high speed impacted is the material buffer structure, both the material buffer structure 2 is worn and torn, also can not cause the whole change of chute, but only change the material buffer structure, both saved time, laborsaving again, can also reduce maintenance, running cost simultaneously.

In the above embodiment, the material buffering structure 2 can be a wear-resistant buffering steel block arranged on the inner side wall in front of the chute body 1, so that the material in operation directly impacts the wear-resistant buffering steel block, and the material is prevented from directly impacting the inner side wall in front of the chute body 1. However, the abrasion of the abrasion-resistant buffer steel block is still faster due to the structure, and the material which can really play a buffering role impacts the abraded material, preferably the flowing material, so that the material cannot be greatly damaged because the material is impacted for a limited time in the running process. Therefore, the application provides a material buffering structure 2 with the following structure, namely, the material buffering structure 2 comprises a storage groove which is fixedly arranged on the inner side wall in front of the chute body 1. Like this, the more material that can strike the storing groove of material of leaking under the high speed, realize the material and strike the material and can not directly dash the purpose of the inside wall in storing groove and chute body 1 the place ahead. At the moment, the storage tank is preferably a triangular storage tank which is fixedly arranged on the inner side wall in front of the chute body 1 through a right-angle side with an upward opening.
