Example 1
As shown in fig. 1, a novel anti-blocking coal bunker comprises a raw coal bunker 1, a raw coal bunker 4, a plug board door 6 and a coal feeder 10, wherein the raw coal bunker 4 is arranged below the raw coal bunker 1, the plug board door 6 is arranged at the bottom end of the raw coal bunker 4, and the raw coal bunker 4 is connected with the coal feeder 10 through an expansion joint 9. The expansion joint 9 is an PZJ-2 type inserted stainless steel sealing expansion joint and is installed at a position about 100mm above an inlet of the coal feeder 10, the inserting plate door 6 is about 800mm away from the coal feeder 10, a first inspection door is arranged at a position close to the inserting plate door 6 below the inserting plate door 6, a second inspection door is arranged at a position close to the inserting plate door 6 above the inserting plate door 6, a third inspection door is arranged at a position 3500mm above the inserting plate door 6, and a fourth inspection door is further arranged at a position 5500mm above the inserting plate door 6. The inspection door is a manhole door, the manhole door can be used for inspection personnel to enter the inspection, and the position of the inspection door is not shown in the figure.
The raw coal hopper 4 is in a hyperbolic shape, better accords with the characteristics of hydromechanics, eliminates factors possibly causing coal fluffing and coal blocking from the structure, simultaneously the raw coal hopper 1 is made of stainless steel, and all welded junctions are polished smooth, so that the friction force between coal and the coal hopper wall can be reduced.
The spile door 6 is replaced by a bidirectional manual spile door from a common unidirectional electric spile door, so that coal adhesion can be prevented, and the coal breakage of the coal feeder 10 can be reduced. Compared with a one-way flashboard door, the two-way manual flashboard door (patent number: ZL200820176247.9) has short stroke and difficult deformation, the drift diameter is 710mm, the flow area is 0.4 square meter, the gap between the rail grooves is small, the opening and the closing are flexible, and the problem that the flashboard door is stuck with coal and is blocked is avoided.
The original raw coal bunker 1 is also provided with a loosening device, but the loosening device is removed in the utility model, because the loosening device occupies space under the normal condition of the raw coal bunker 1, the loosening device has an obstruction effect on coal flow and influences the flow of the coal flow; when the raw coal bin 1 is stuck with coal, the loosening device is started to play a role in dredging, and once the raw coal bin 1 is in failure, adverse effects are caused (for example, the loosening device is bent and deformed to block coal flow to form coal blockage, and if the loosening device is broken due to a connecting part, the loosening device loses the function of dredging to cause unsmooth coal flow), the sticking and the blockage of the raw coal bin are aggravated, so that the loosening device must be detached to increase the flow area at the outlet of the raw coal bin 1.
The four groups of bin wall rapping air hammers replace four groups of bin wall rapping air hammers, the bin wall rapping air hammers are arranged on the outer wall of a raw coal bin 1 and can replace the traditional manual mode that hammers are used for rapping the bin wall, coal slag on the bin wall is shaken down through air rapping, the protection effect on the bin wall is simultaneously played, a first bin wall rapping air hammer 2 and a second bin wall rapping air hammer 3 are arranged at the joint of the raw coal bin 1 and a raw coal hopper 4, and a third bin wall rapping air hammer 7 and a fourth bin wall rapping air hammer 8 are arranged between an inserting plate door 6 and an expansion joint 9.
The raw coal hopper 4 is provided with an automatic filtering and draining device 5, the coal feeder 10 is provided with a coal breakage signal acquisition device 11, and the first bin wall vibrating air hammer 2, the second bin wall vibrating air hammer 3, the third bin wall vibrating air hammer 7, the fourth bin wall vibrating air hammer 8, the automatic filtering and draining device 5 and the coal breakage signal acquisition device 11 are all electrically connected with the control device. As the coal slime is mixed and burnt, moisture can be generated in the coal bin, the automatic filtering and draining device 5 can actively drain the moisture in the air to keep the interior of the bin dry, the automatic filtering and draining device 5 also normally operates when the coal breaking signal acquisition device 11 detects that the coal feeder normally operates, and sends out a signal when the coal breaking signal acquisition device 11 detects that the coal feeder has a coal breaking phenomenon, at the moment, the first bin wall rapping air hammer 2, the second bin wall rapping air hammer 3, the third bin wall rapping air hammer 7 and the fourth bin wall rapping air hammer 8 start to operate in turn, and the alternate blowing rapping and the rapping gradually dredge.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
