Abstract
The utility model belongs to the technical field of pulverized coal combustion system equipment, in particular to a safe purging device for an explosion door of a powder collector, wherein the explosion door (1) is obliquely arranged, an air blowing pipeline (2) is arranged at the bottom of the explosion door (1), and a filter screen (3) is obliquely arranged on the upper end surface of the air blowing pipeline (2); the angle between the filter screen (3) which is obliquely arranged and the ground is more than 45 degrees; the wind of the blowing pipeline of the device passes through the filter screen, can effectively blow away the dust accumulated at the doorway, and ensures the walking safety of the working personnel on the premise of effectively clearing away the accumulated coal dust at the doorway.
Description
Technical Field
The utility model belongs to the technical field of pulverized coal combustion system equipment, especially, relate to a receive powder ware explosion vent safety and sweep device.
Background
The coal powder preparation belongs to the production technology with higher danger coefficient, wherein the coal powder preparation is used as a powder collecting device for collecting coal powder and is one of systems with multiple accidents.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an effectual problem among the above-mentioned background of solution has proposed a receive powder ware explosion vent and has swept device safely, and concrete technical scheme is as follows:
the safe purging device for the explosion door of the powder collector is characterized in that the explosion door (1) is obliquely arranged, an air blowing pipeline (2) is installed at the bottom of the explosion door (1), and a filter screen (3) is obliquely arranged on the upper end face of the air blowing pipeline (2); the inclined filter screen (3) forms an angle of more than 45 degrees with the ground
Compared with the prior art, the beneficial effects of the utility model reside in that: the wind of the blowing pipeline of the device passes through the filter screen, can effectively blow away the dust accumulated at the doorway, and ensures the walking safety of the working personnel on the premise of effectively clearing away the accumulated coal dust at the doorway.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the technical personnel in the technical field understand the scheme of the invention better, the invention is further explained in detail with the attached drawings and the embodiment;
a safe purging device for an explosion door of a powder collector is characterized in that the explosion door 1 is obliquely arranged, an air blowing pipeline 2 is installed at the bottom of the explosion door 1, and a filter screen 3 is obliquely arranged on the upper end face of the air blowing pipeline 2; the angle between the filter screen 3 which is obliquely arranged and the ground is more than 45 degrees;
the purpose of forming an included angle between the filter screen 3 and the ground is to ensure that the blowing of wind keeps an inclined angle with the horizontal plane, the blown dust flows inwards, and the wind can effectively blow away the dust on the ground when the included angle is more than 45 degrees;
the wind of the blowing pipeline of the device passes through the filter screen, can effectively blow away the dust accumulated at the doorway, and ensures the walking safety of the working personnel on the premise of effectively clearing away the accumulated coal dust at the doorway.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
