Sliding frame arch breaking method of stock bin

Abstract

The invention discloses a sliding frame arch breaking method of a stock bin. The sliding frame arch breaking method comprises the following steps that (1) an infrared sensor judges whether arch camber exists or not to enter a next step to work; (2) a controller controls a hydraulic system to carry out arch breaking; (3) the infrared sensor simultaneously and continuously judges whether the arch camber exists or not in the previous steps so that the infrared sensor judges that a material has no arch camber after the material is subjected to the arch breaking, so that a detecting system feeds back signals to the controller, and the hydraulic system stops working.

Description

technical field [0001] The invention relates to the field of silos, in particular to a method for breaking dewatered sludge or high-viscosity materials by using a sliding frame in a silo. Background technique [0002] At present, during the storage of materials, relying on the gravity of the materials themselves to make the materials flow to the outlet of the silo, it is easy to cause arching, sticking, and blockage of the materials in the silo, especially when the material contains a large amount of water, mud or the material itself When the viscosity is high, the adhesion of the material is stronger, and the silo blockage of different degrees is more likely to occur. Once the silo is blocked, it will not only affect the full play of the silo, but also seriously damage the continuity of the production process. At present, arch breaking by slide frame is an arch breaking method that is widely used and has high reliability. In the method, an arch-breaking carriage is arrang...

AI Technical Summary

Problems solved by technology

The following problems exist in the use of hydraulically driven carriages to break the arch: (1): Since the arching of the material does not always exist, when the arch is destroyed, the material can sometimes be unloaded by itself relying on its own gravity, and the arching sometimes exists and sometimes does not exist. At present Some methods can be used to judge the arching of materials

This method can effectively determine whether the powder is arching, but it needs to use a material scale, and when the density of the material and the discharge speed change, the accuracy of arching judgment is not enough

Moreover, this method uses high-pressure gas to break the arch, which is difficult to realize for high-viscosity materials such as sludge; (2) when the hydraulic drive system is driven by a single cylinder, the force on one side of the carriage is unbalanced, and when the hydraulic drive system is driven by two cylinders, the synchronization accuracy is relatively low. Low, it is easy to have a large position error after running for a long time
