Brief description of the drawings
Fig. 1 is a kind of structural representation of embodiment of defeated coal device that the present invention is provided.
Fig. 2 is a kind of structural representation of specific set-up mode of spring that the present invention is provided.
Embodiment
Following examples are used to illustrate the present invention, but are not limited to the scope of the present invention.
As shown in figure 1, the present invention provides a kind of fire prevention defeated coal device of Wind-Pressure Resistance, the defeated coal device includes upper pipe setting up and down
Body 100 and lower tube body 200, the top of the upper tube body 100 are provided with venting 104, and bottom end opening stretches into the lower tube body 200
Top in and be tightly connected with the lower tube body 200, the bottom of the lower tube body 200 connection boiler furnace, the upper pipe
The side on the top of body 100 is provided with the opening connected with belt conveyer 300；The bottom end opening of the upper tube body 100 is hinged with
Turnover panel 101, the turnover panel 101 is supported the bottom end opening that seals the upper tube body 100 by spring 102 and by from belt conveyer
The Action of Gravity Field of 300 coal materials is opened；The middle part of the lower tube body 200 is provided with electricity, pneumatic operated valve 201, the electricity, pneumatic operated valve
201 opening and closing synchronous with belt conveyer 300.
The specifically used mode of the defeated coal device of the present invention is：Coal charge is delivered in upper tube body by belt conveyer, is then passed through
Turnover panel and spring that upper tube body bottom is set are oppressed, turnover panel is opened, hence into lower tube body, is started in belt conveyer
While, while being opened by same button control electricity, pneumatic operated valve, so that coal charge enters in boiler furnace, and work as belt
When transporter stops conveying coal charge, turnover panel and electricity, pneumatic operated valve are turned off.
In the present invention, the quantity of turnover panel can be 1~8, for example, as shown in Figure 1-2, described one end of spring 102 is supported
