According to the embodiment of the invention, the upper valve body is provided with the inspection hole.
According to an embodiment of the invention, the emergency discharge opening is arranged above a high level of the ash hopper.
The accident ash discharging port is arranged, so that the ash deposition hidden danger of an ash bucket for operating the dust removing equipment is eliminated and reduced, and the safe and stable operation of the dust remover is ensured.
Under the action of gravity of appropriate materials, the first turning plate is opened outwards, the materials fall into the ash discharging hopper to which the valve body belongs, when the materials in the ash discharging hopper are accumulated to a certain weight, the second turning plate is opened outwards, the materials are discharged downwards, and dust overflows out of the ash discharging hopper, so that the condition that the ash discharging hopper is overloaded can be effectively avoided, and safety accidents are prevented.
The assembly of the first counterweight rod and the first counterweight and the weight of the first counterweight are adjusted by controlling the stacking height of materials, the stacking density of the materials, the angle of a wall plate of the ash bucket, the sealing of the ash bucket and the like according to requirements.
The invention adjusts the assembly of the second counterweight rod and the second counterweight and the weight of the second counterweight by controlling the weight of the material stack, the material stack density, the sealing of the valve body and the like according to requirements.
The ash discharging hopper is used for temporarily storing ash, and the volume of the ash discharging hopper is balanced with the second plate turnover device.
The inspection hole is used for inspecting whether foreign matters are blocked in the valve body or not, and whether the first turning plate is normally opened or closed or not is determined.
Hard sealing and soft sealing can be adopted between the first valve plate of the first turning plate and the ash bucket wall plate and between the second turning plate and the ash bucket, and the soft sealing is selected according to the tightness requirement of the dust removing equipment.
The beneficial technical effects of the invention are as follows: (1) an accident discharge opening is additionally arranged at the middle upper part of an ash hopper of the dust remover, and dust higher than the safety warning height is directly discharged by utilizing the self-weight ash discharging principle of a flap valve, so that the accident ash storage amount of the ash hopper is not too large, the potential safety hazard is reduced, and in addition, the device can also be used as an emergency ash discharging opening; (2) the device has simple structure, simple manufacture and lower cost, and improves the structure on the basis of the traditional self-weight discharge valve; (3) the ash bucket is convenient to install, and can be fixedly installed at a proper height of the ash bucket, symmetrical installation is suggested, and ash unloading is more timely and smooth.
