Description

Multi-layer blocking-removing crushing device for cement reservoir bottom Technical Field The utility model belongs to the technical field of cement production and storage equipment, and particularly relates to a multi-layer blockage-removing and crushing device for a cement reservoir bottom. Background In the cement production process, homogenization treatment is needed, and the finished cement product is also needed to be stored, so that a cement factory is usually provided with a cement silo with large capacity, and the storage amount is generally not less than 7t. In order to reduce the pressure of the pressure generated by the dead weight of the materials to the discharge hole of the bottom of the cement silo, a decompression structure such as a decompression cone is arranged above the discharge hole of the bottom of the cement silo. In the cement homogenization or storage process, due to large storage capacity and long storage time, cement is easy to form caking in the cement silo bottom and the discharging channel, and the caking cement is required to be poked and crushed, so that the phenomenon that the discharging opening is blocked by the cement caking, so that the discharging efficiency is affected is avoided. The device is limited by the capacity of a cement silo and the arrangement of a decompression cone at the bottom of the silo, the device cannot be suitable for the process of probing and poking materials from the bottom of the silo and crushing the bottom of the silo in the prior art, and the mode that the poking materials and the crushing mechanism are simultaneously arranged at the bottom of the silo also has space interference, so that the simultaneous operation of poking materials and crushing cannot be realized, the continuous unloading is difficult, and the production efficiency is low. Accordingly, in part of the prior art, such as CN212268388U, the material poking mechanism and the crushing mechanism are integrated on one device, and in the crushing operation, the material poking operation can be performed on the blanking channel at the same time, so that the problem of continuous operation is solved. But this type of equipment adopts single broken axle or two broken axles that set up side by side to carry out crushing operation to the cement piece that falls generally, has the energy consumption height, and crushing efficiency is low, and the cement particle after the breakage is not thin enough, the poor problem of homogeneity.
