Automatic dredging type coal discharging hopper

Abstract

The invention provides an automatic dredging type coal discharging hopper. The automatic dredging type coal discharging hopper is provided with a stepped hopper body. An automatic dredging device is fixed into the hopper body and provided with a dredging rod with one end provided with a thread. The threaded end of the dredging rod is connected with a dredging cone and the other end is connected with fan blades. An upper fixing sleeve, a pressure bearing, a spring and a lower fixing sleeve are sequentially arranged on the dredging rod from top to bottom. The upper fixing sleeve is fixedly arranged on the dredging rod. The fan blades rotate after bearing force. The dredging rod is driven by the fan blades to rotate for automatic dredging operation.

Description

technical field [0001] The invention relates to a coal drop hopper used in a thermal power plant, in particular to a coal drop hopper with automatic dredging and anti-blocking functions. Background technique [0002] For a long time, an important problem that has plagued the operation of power plants is the frequent blockage of the coal hopper, especially in rainy days when the surface moisture of the coal is high. The clearing method is as follows: 1. It requires the staff to beat and dredge every day. The disadvantage of this method is that it wastes manpower and material resources, and can only be carried out at fixed points and regularly. If there is a blockage during operation, the entire process must be stopped to clear it. 2. In the A dynamic vibrating component is installed outside the coal scuttle to reduce clogging by vibrating the outside of the coal scuttle. The disadvantage of this method is that the loose coal material can be shaken off by vibration, but in rai...

[0002] For a long time, an important problem that has plagued the operation of power plants is the frequent blockage of the coal hopper, especially in rainy days when the surface moisture of the coal is high. The clearing method is as follows: 1. It requires the staff to beat and dredge every day. The disadvantage of this method is that it wastes manpower and material resources, and can only be carried out at fixed points and regularly. If there is a blockage during operation, the entire process must be stopped to clear it. 2. In the A dynamic vibrating component is installed outside the coal scuttle to reduce clogging by vibrating the outside of the coal scuttle. The disadvantage of this method is that the loose coal material can be shaken off by vibration, but in rainy days, the humidity of the coal material increases, and the vibration may increase. The density of the coal material further tamps the coal material and makes it more difficult to clean
