Description
Technical Field
The application relates to the field of feeding devices, in particular to a horizontal powder bin with an arch breaking device.
Background
The powder bin is used as a main container for storing powder in a concrete mixing plant, the powder bins on the market are more vertical bins, the height of the vertical bins is higher and generally reaches nearly 25m, certain difficulty is caused in field installation and transportation, and the hidden danger of use exists particularly in places with dense high-voltage transmission lines.
Although some manufacturers have developed horizontal powder tanks with lower height in China, the powder tanks still face the situation of arch-forming bridging and unsmooth blanking of powder in the tanks. The powder arching in the powder bin can lead to the material to carry smoothly, seriously influences production efficiency. At present, basically all horizontal powder bins have similar structures. Differences in breaking of arches of the main differences
The traditional method for solving the problem of powder arch camber at present comprises manual knocking arch breaking, vibration arch breaking, airflow arch breaking, arch breaking by a stirring device and the like. The manual knocking arch breaking is basically cancelled due to low efficiency and damage to equipment, and currently, the manual knocking arch breaking mainly comprises arch breaking by a vibration motor, arch breaking by airflow and arch breaking by a stirring device. However, when the arch of the vibration motor is broken, the excitation force of the vibration motor causes the material to flow, so that the material cannot flow again sometimes, but the material is compacter, and in addition, due to the characteristic of multiple discharge ports of the horizontal powder bin, if the material collapses suddenly after the arch is formed, the load of the rotating shaft of the screw machine is increased, and the motor is easy to damage. The air flow arch breaking mainly adopts pressurized air as power, impact force is formed in an instant release mode, and arch breaking is achieved, but the arch breaking mode can blow a hole for some materials, and the fluidization effect cannot be achieved. The arch breaking success rate of the stirring device is higher relatively, and many stirring type arch breakers at present are stirred by arranging some scraping plates or stirring straight rods in a bin, so that the stirring straight rod mode similar to a mode that a main body is provided with branched stirring straight rods has more obvious effect on powder disturbance, but also provides some supporting points for materials, and bridging and arching are easier to form.
