Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The following detailed description is provided to illustrate specific embodiments of the present invention.

Referring to fig. 1 to 2, a pulverized coal dust suppression device according to an embodiment of the present invention includes: discharge hopper 1, buggy storehouse 2 and ash bucket platform 3.

In the embodiment of the present invention, please refer to fig. 1 and 2, the discharge hopper 1 is erected at the middle position of the top of the pulverized coal bunker 2, and the pulverized coal bunker 2 is erected with the ash hopper platform 3, the air duct pipe 4 communicated with the ash hopper platform 3 is fixedly embedded on the ash hopper platform 3, and the other end of the air duct pipe 4 is communicated with the through hole formed on the side wall of the discharge hopper 1, while the bottom pipe of the discharge hopper 1 passes through the ash hopper platform 3 and extends into the pulverized coal bunker 2, the fixing frame on the ash hopper platform 3 is provided with the explosion-proof dust remover 5, the explosion-proof dust remover 5 is communicated with the ash hopper platform 3 through the pipeline, and the exhaust pipe of the explosion-proof dust remover 5 is communicated with the explosion-proof fan 6 fixedly embedded on the ash hopper platform 3;

the ash bucket platform 3 is provided with a crane 9b, and the ton bag 9a filled with pulverized coal is lifted by the crane 9 b.

It should be noted that: the ton bag 9a that is equipped with the buggy promotes to discharge hopper 1 department through hoist 9b in the workshop, and the manual work is gradually fallen into the discharge hopper 1 with the buggy through cutting ton bag 9a and then gets into in the middle of the buggy storehouse 2, and before concrete preparation split packing: starting a fan in the explosion-proof dust remover 5, emptying air in the ash bucket platform 3, simultaneously forming a negative pressure area at the discharge hopper 1, manually cutting a ton bag 9a to dump coal powder, and sucking a large amount of raised dust into the ash bucket platform 3 through an air duct pipe 4 at the inner side of the discharge hopper 1;

the coal dust suppression device is arranged at the top of the middle coal dust bin 2 in a whole set, so that the space of a coal storage room is greatly saved, and the explosion-proof dust collector 5 directly falls the collected coal dust into the middle coal dust bin 2, so that a dust falling hopper is omitted, and the space in height is also saved.

Compared with the prior art, after the device is started, a large amount of raised dust can be sucked into the coal dust bin 2, the dust is greatly reduced on the operation surface of an operator, the efficiency of splitting the coal dust package of the ton bag 9a is also improved, when a large amount of air exists in the coal dust bin 2, the phenomenon that the coal dust is not smoothly discharged due to the fact that the local positive pressure is generated when the coal dust of the ton bag 9a falls into the coal dust bin is caused, the air in the explosion-proof dust collector 5 can be pumped away after the explosion-proof dust collector is started to form a micro-negative pressure state, the discharged dust is smooth, and meanwhile, the dust escaping to the periphery can also enter the dust hopper table 3;

and the whole dust collection system utilizes the space at the top of the coal dust bin 2, the discharge hopper 1 and the explosion-proof dust collector 5 are all arranged at the top of the bin, the space is not occupied, and meanwhile, the middle powder bin is used as the dust hopper of the small dust collector, so that the height space is reduced.

The explosion-proof electric butterfly valve 7 is mounted on an exhaust pipe connected with the explosion-proof fan 6 of the explosion-proof dust remover 5, and the arranged explosion-proof electric butterfly valve 7 is mainly used for closing an outlet of the explosion-proof dust remover 5 to prevent inert gas from overflowing when an inert gas protection device of a conveying system of the explosion-proof dust remover 5 acts, so that temperature protection of the middle pulverized coal bunker is realized.

In the embodiment of the present invention, referring to fig. 1, a filter bag 8 is embedded in the ash bucket table 3, the air duct pipe 4 extends into the ash bucket table 3 and is located on the upper surface of the filter bag 8, a pulse injection system is disposed in the ash bucket table 3, and two electric side hung doors 9 are installed in the discharge hopper 1;

it should be noted that: intercept the dust on 8 surfaces of filter bag through the filter effect of filter bag 8, clean gas passes through 6 discharges of explosion-proof fan, and the dust that intercepts on 8 surfaces of filter bag trembles the dust through the pulse injection system in middle buggy storehouse 2, and the pulse injection system that sets up in this application is prior art, give unnecessary details here, and two electronic vertical hinged doors 9 of design, when adding the buggy to buggy storehouse 2, open two electronic vertical hinged doors 9 and make 1 entrance of discharge hopper expand, thereby conveniently add the buggy to buggy storehouse 2, and when mending 2 interpolation buggy to buggy storehouse, it closes up and makes 1 entrance of discharge hopper sealed to start two electronic vertical hinged doors 9, it leaks to have avoided discharge hopper 1 department to appear the buggy.

The utility model discloses circuit and control that relate to are prior art, do not carry out too much repetition here.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
