Abstract
The utility model discloses a coal blocking preventing and alarming device for a belt conveyor head. The coal blocking preventing and alarming device comprises a belt conveyor, a coal drop, a power source, an alarming prompting lamp, an alarming ring, a trigger switch, a fulcrum, a lever and a collection shovel. The lower end of the coal drop is provided with a coal outlet, the head of the belt conveyer is located on the upper portion in the coal drop, one side of the middle of the coal drop is provided with a coal overflow opening, and the lower portion of the coal overflow opening is provided with the collection shovel. The collection shovel is fixed to one end of the lever, and the other end of the lever is provided with the trigger switch. The lever is supported by the fulcrum, and the trigger switch is sequentially connected with the power source, the alarming prompting lamp and the alarming ring to form a closed circuit. The coal blocking preventing and alarming device has the advantages of being safe, reliable, capable of giving an alarm automatically and reminding workers in time and the like.
Description
Technical field
The utility model relates to a kind of for preventing that coal-burning power plant from slipping the stifled warning device of the anti-coal of belt conveyer head that coal cylinder stops up.
Background technology
In order to reduce circulating fluidized bed combustion coal boiler cost of electricity-generating, many Comprehensive Utilization Power Plant have been implemented diversification fire coal and have been mixed firing technique in recent years.Due to coal slime low price and source abundant, the utilization of coal slime increases year by year, along with coal slime is mixed the increase of burning amount, the fuel ratio that causes combustion fortune workshop to carry is wet sticky, in the time of production run, belt conveyer head slips the stifled fault of the inner coal of coal cylinder and often occurs, and has had a strong impact on the safe and smooth operation of combustion fortune system.At present mainly rely on workman to patrol and examine to check, report to the police and artificial treatment to slipping the stifled fault of coal cylinder coal, safety in production is moved and brings very large harm.First, the stifled fault of the coal cylinder generation coal that slips is not found to process in time, just there will be the coal that overflows to spread coal phenomenon, increases operations staff's labour intensity; Secondly, the coal cylinder chute blockage that slips is not processed in time, chute blockage pressure will occur and bury belt feeder driving drum phenomenon, thereby the operational outfit that causes belt to kill is abnormal, the severe accident that can cause belt to break when serious.
Summary of the invention
The purpose of this utility model is to provide a kind of safe and reliable, automatic alarm, can remind in time workman to process the stifled warning device of the anti-coal of belt conveyer head of the stifled fault of coal.
To achieve these goals, the utility model comprises: belt feeder, slip coal cylinder, power supply, alarm lamp, emergency alarm bell, trigger switch, fulcrum, lever, collection shovel, be provided with coal outlet in the lower end of staying coal cylinder, the head of belt feeder is positioned at and slips the internal upper part of coal cylinder, have an excessive coal mouth slipping middle part one side of coal cylinder, the bottom of excessive coal mouth is provided with collects shovel, collect shovel and be fixed on lever one end, the other end of lever is provided with trigger switch, lever is supported by fulcrum, and trigger switch forms close circuit with power supply, alarm lamp, emergency alarm bell successively.
Under normal circumstances, belt feeder is transported to fire coal to slip coal cylinder inside, is oozed by coal outlet control, in the time that coal outlet occurs to stop up, along with the running of belt feeder, the fire coal slipping in coal cylinder will be piled high gradually, in the time reaching the excessive coal mouth position at middle part, fire coal will flow out from the coal mouth that overflows, the fire coal flowing out drops to be collected in shovel, collects shovel and increases the weight of to fall to moving by lever drives trigger switch, trigger switch closure, whole circuit is connected, and alarm lamp, emergency alarm bell send sound and light alarm signal; Workman can process blockage problem in time, avoids that the excessive coal that causes spreads coal phenomenon and belt kills the accident of breaking because stopping up.There is safe and reliable, automatic alarm, remind the features such as workman in time.
brief description of the drawings:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is block construction schematic diagram of the present utility model.
detailed description of the invention:
As shown in Figure 1, the utility model comprises: belt feeder 1, slip coal cylinder 2, power supply 3, alarm lamp 4, emergency alarm bell 5, trigger switch 6, fulcrum 7, lever 8, collect shovel 10.Be provided with coal outlet 9 in the lower end of staying coal cylinder 2, coal outlet is provided with by-pass valve control, can control the flow that produces coal.The head of belt feeder 1 is positioned at and slips the internal upper part of coal cylinder 2, for to slipping transporting buring coal in coal cylinder.Have an excessive coal mouth 11 slipping middle part one side of coal cylinder 2, the bottom of the coal mouth that overflows is provided with collects shovel 10, and the fire coal that the coal mouth that overflows flows out can accurately flow into be collected in shovel.Collect shovel 10 and be fixed on lever 8 one end, the other end of lever 8 is provided with trigger switch 6, and lever is supported by fulcrum 7, while thering is no fire coal in collection shovel, collecting shovel one end lifts, trigger switch disconnects, and collection flows in shoveling while having fire coal and collects and shovel whereabouts, one end, trigger switch closure.Trigger switch 6 forms close circuit with power supply 3, alarm lamp 4, emergency alarm bell 5 successively, and when trigger switch is closed, alarm lamp, emergency alarm bell can carry out sound and light alarm.
