Storage hopper cone hopper slow-storage type low-amplitude arch breaking device

Technical Field

The utility model relates to a cement manufacture field especially relates to the broken ware that encircles of low amplitude of storage bin awl fill slow-storage formula.

Background

At present, most of storage bins achieve the conveying purpose by means of the gravity of materials and an external wall vibration device, the materials can fall down automatically, and the phenomenon of blockage and adhesion is easily caused by the fluctuation of the moisture of the materials. Once the phenomenon occurs and the continuity of the production process cannot be influenced, workers on duty need to immediately carry out manual dredging at the bottom of the cone hopper, the working mode is dangerous, a large amount of materials are accumulated at the top of the storage bin, once the blocked part at the bottom is cleared, the materials at the top are extremely prone to falling down, if the workers do not dodge in time, safety accidents can occur, and the cone hopper wall is vibrated and cracked, welded and the like due to continuous vibration.

The Yinan Zhongli cement company is a whole capital company of China Union Cement group company limited under China building materials flag, the whole equipment is well operated since the production, but the arch camber phenomenon of a material bin of a batching station is not completely eliminated all the time, particularly when the moisture of materials stacked in the open air is increased, the materials are easy to arch and block, and further the grinding process can not meet the requirement of accurate proportion and continuous production, when the materials are transferred to the material bin from the tail end of a conveying belt, the void ratio is improved due to free accumulation, because the materials have various shapes and unfixed shapes, the surface roughness of the materials is different, and the materials have certain initial viscosity, so that the particles of the materials are mutually staggered and occluded, an arch bridge-shaped space is formed, the bridging agglomeration phenomenon is caused by that the friction force between the materials and the bin wall is larger than the gravity of the materials, and the situation is more practical and more practical along with the improvement of the materials, the materials are easy to adhere to each other and to the wall of the silo, and the material specification is small, the crushed materials are too many, and the gaps between the raw materials are small. The contact area is large, so that the friction force between materials and between the materials and the bin wall is increased.
