AI Technical Summary
When handling soot, traditional wrapping star unloaders have ash scabs stuck in the inner wall of the cylinder, and the maintenance frequency is high. The ash discharge device is prone to cracking the base of the cycloid pin wheel reducer and the transmission chain breakage, resulting in maintenance. Unsafe, the service life of the inner angular contact rolling bearing of the external support cage is shortened.
A star -shaped unloader is designed, including the shell, the unloading cylinder, the windshield, the side cover of the unloading cylinder, and the rotating unloading device. By setting up a larger feed inlet and discharge port, the ash excavation ability is increased to prevent blocking; the windshield is set between the shell and the unloading cylinder to separate the cavity to reduce the probability of air leakage.
The design increases the ash discharge ability, reduces the risk of blockage, reduces the frequency of maintenance, improves the service life of the equipment, and ensures the safety of maintenance by reducing the probability of air leakage.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of unloading devices, and in particular relates to a star-shaped unloader. Background Art
[0002] In the prior art, the traditional wrapped star-shaped discharger is suitable for ash discharge devices with high dryness and without any block materials. During the use of the traditional wrapped star-shaped discharger, the cylinder adopts a wrapped ash discharge method, and the upper and lower inlets and outlets of the ash discharge adopt a closed ash discharge method. The contact surface between the ash discharge rotating roller and the cylinder is 60%-70%, and the external cage supports the internal angular contact bearing to increase the force transmission capacity. The reserved hole on the outside of the cylinder is narrow and cannot meet the maintenance needs of the inspectors according to the limitation of the wrapped semi-arc.
[0003] During the operation of the traditional wrapped discharger, since the ash produced by the electrostatic precipitator ash hopper has a high viscosity and a temperature of 70°C, the contact area between the rotating roller of the traditional wrapped star discharger and the cylinder is large, resulting in serious adhesion and scabbing of the inner wall of the cylinder, and a high frequency of maintenance. At the same time, it causes the base of the cycloid pinwheel reducer to crack and the transmission chain to break. The maintenance personnel cannot ensure safety in handling jams and faults, and the service life of the angular contact rolling bearing inside the external support cage is shortened.
[0004] The above situation causes the ash removal device which does not require frequent maintenance to require regular maintenance, and at the same time increases the workload of the maintenance personnel. Utility Model Content
