Abstract
The utility model discloses a stone coal feeder, relating to the technical field of a conveying system. The stone coal feeder comprises a stone coal hopper; a feed port is arranged at the upper part of the stone coal hopper; the bottom of the stone coal hopper is connected with a negative-pressure main pipeline; and the stone coal feeder is characterized in that: the bottom of the negative-pressure main pipeline is connected with a blowing pipeline, and the negative-pressure main pipeline is arranged obliquely. The stone coal feeder disclosed by the utility model has a simple structure and operates reliably; and through the blowing pipeline, the jam is prevented in the conveying process, and the packing and feeding processes are smooth.
Description
Technical field
The utility model relates to the induction system technical field, is specifically related to a kind of stone coal feeder.
Background technology
Medium-speed pulverizer is owing to small investment, good economy performance obtain widely applying in thermal power plant.Medium-speed pulverizer can produce the stone coal in running, the stone coal is mainly derived from big, the difficult spoil that grinds of density, pyrite etc. in the raw coal, and its stone coal floss hole from its underpart when coal pulverizer moves is discharged.The stone coal needs discharging in time; If stone coal discharging is untimely, bulk deposition in coal pulverizer causes scraper plate, carbon sealing wear easily or comes off; The stone coal of piling up also can stop up the air channel; Under the effect of hot blast, catch fire, coal pulverizer parts such as scaling loss air channel, scraper plate and stone coal bin cause the coal pulverizer fault to stop transport.
Common stone coal discharging has forms such as manual emission, waterpower discharging, mechanical transport discharging.At present; Because power plant's coal is changeable; The general variation of raw coal ature of coal, foreign material such as stone, spoil, ore increase than before in the raw coal, and stone coal discharge capacity increases greatly; Have a strong impact on the safe operation of thermal power plant, conventional stone coal discharging modes all are difficult to solve the problem that present stone coal amount increases greatly.
Recent domestic minority power plant handles the stone coal and has adopted air-transport system.Using the air-flow of motion to be the medium transport material, is the transportation resources of using already in the industry, is called strength and carries.The advantage of air-transport system is: simple in equipment, transfer efficiency is high, labour health condition is good.The conveyance conduit that strength is carried is provided with pipe network with being convenient to suit measures to local conditions, arranges easy to be flexibly, can make full use of the workshop area, is easy to adapt to workshop condition.
But the air-transport system that is applied to the conveying of stone coal at present is mainly the negative-pressure adsorption system, but in practical application, also has more problem, mainly shows as: 1, the pipeline clogging takes place easily, do not dredge measure after the obstruction; 2, the scene still has dust to reveal, and the system failure is more; 3, system's conveying capacity is not high.
The utility model content
The utility model technical problem to be solved is to provide a kind of high efficiency, and charging is stone coal feeder smoothly.
The utility model technical problem to be solved adopts following technical scheme to realize:
Stone coal feeder comprises the stone coal bunker, and said stone coal bunker top is provided with charging aperture, and said stone coal bunker bottom is connected with the negative pressure trunk line, it is characterized in that: said negative pressure trunk line bottom is connected with the blowing pipeline, and described negative pressure trunk line is obliquely installed.
Said charging aperture place is provided with a material stopping valve.
Described blowing pipeline is provided with air intake control valve.
The beneficial effect of the utility model is: the utility model is simple in structure, and is reliable, through the setting of blowing pipeline, makes bite can not occur in the course of conveying that the packing charging is smooth and easy.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Like Fig. 1, stone coal feeder comprises stone coal bunker 1; Stone coal bunker 1 top is provided with charging aperture 2, and stone coal bunker 1 bottom is connected with negative pressure trunk line 4, and negative pressure trunk line 4 bottoms are connected with blowing pipeline 5; Negative pressure trunk line 4 is obliquely installed; Charging aperture 2 places are provided with a material stopping valve 3, are used to control inlet amount, and blowing pipeline 5 is provided with air intake control valve 6.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
