Abstract
The utility model relates to the technical field of coal feeding, in particular to a coal feeding system capable of judging coal blockage and coal interruption. The coal feeding system comprises a coal feeder, a pressure transmitter and a DCS (distributed control system) control cabinet, wherein the pressure transmitter is connected with a coal feeder, and the DCS control cabinet is connected with the pressure transmitter. An operator can monitor whether the coal feeder is subject to coal blockage or coal interruption in real time according to variation of pressure on the DCS control cabinet, and therefore not only allocation of spot operators is reduced, but also failure of the coal feeder is greatly reduced, safety and stability of operation are enhanced, maintenance amount of coal feeder failure is reduced and then stoppage rate is reduced.
Description
Technical field
The utility model relates to the coal supply technical field, is specifically related to a kind of coal supply system that can in time judge chute blockage, disconnected coal.
Background technology
Coal supply system is very crucial accessory system in boiler operatiopn, and feeder generation chute blockage in service, disconnected coal will directly influence the safe operation of boiler, more likely cause blowing out.Do not go under the coal at feeder coal unloading tube place during chute blockage, be equivalent to feeder and stop transport, measure for a long time that coal stops up out ort, fill up feeder inside and cause cleaning the chain cisco unity malfunction even the cleaning chain is broken; Feeder overload overcurrent tripping.Disconnected coal may cause the feeder door section overtemperature that produces coal, and burns measuring probe (sideslip switch, rotational speed probe etc.), even burns the feed belt of feeder, causes feeder to be stopped transport; Feeder is stopped transport and to be caused the load pressure fluctuation, even causes the boiler blowing out of stopping working.
Yet, in the prior art, can't in time judge feeder whether be in operation chute blockage, disconnected coal, not only influenced operating efficiency, and very easily caused the accident.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of coal supply system that can in time judge chute blockage, disconnected coal is provided.
The utility model is realized by following technology.
A kind of coal supply system that can in time judge chute blockage, disconnected coal comprises feeder, also comprises the pressure transmitter that links to each other with feeder, the DCS switch board that links to each other with described pressure transmitter.
Preferably, described feeder offers pressure port, and described pressure port is connected with sampler barrel, and described sampler barrel links to each other with described pressure transmitter.
Preferably, described sampler barrel is installed anti-block apparatus.
Preferably, described pressure port is positioned at the top of described feeder.
Preferably, the inside of described feeder is provided with feed belt.
Preferably, the top of described feeder is provided with coal inlet, and the below of described feeder is provided with out ort.
Preferably, described pressure port is with described to go out ort corresponding.
The beneficial effects of the utility model are: this kind can in time be judged the coal supply system of chute blockage, disconnected coal, comprises feeder, also comprises the pressure transmitter that links to each other with feeder, the DCS switch board that links to each other with described pressure transmitter.The operations staff on the DCS switch board according to the variation of feeder pressure just can the real time monitoring feeder whether disconnected coal or chute blockage, not only reduced field operator's configuration, and greatly reduce the feeder fault, increase the security and stability of operation, reduce the maintenance of coal machine fault, thereby reduced the probability of blowing out.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, comprise among Fig. 1:
1---feed belt
2---coal inlet
3---go out ort
4---sampler barrel
5---pressure transmitter
6---the DCS switch board.
The specific embodiment
For the ease of those skilled in the art's understanding, below in conjunction with embodiment and accompanying drawing the utility model is further described, the content that embodiment is mentioned not is to qualification of the present utility model.
See Fig. 1, a kind of coal supply system that can in time judge chute blockage, disconnected coal comprises feeder, also comprises the pressure transmitter 5 that links to each other with feeder, the DCS(dcs that links to each other with described pressure transmitter 5) switch board 6.The operations staff on DCS switch board 6 according to the variation of feeder pressure just can the real time monitoring feeder whether disconnected coal or chute blockage, as when feeder pressure increases fast, the judgement feeder is the situation of chute blockage; When feeder sealing blast reduces (other feeders relatively), judge that feeder is the situation of disconnected coal.In this way, not only reduce field operator's configuration, and greatly reduced the feeder fault, increased the security and stability of operation, reduced the maintenance of coal machine fault, thereby reduced the probability of blowing out.
Described feeder offers pressure port, and described pressure port is connected with sampler barrel 4 by pipeline, and described sampler barrel 4 and described pressure transmitter 5 link to each other by pipeline.Described sampler barrel 4 is installed anti-block apparatus, prevent that some short grained coal dusts in the feeder from kicking up and block sampler barrel 4 and pipeline thereof, influence is to pressure measxurement, anti-block apparatus is according to the different devices that separate of the proportion of gaseous exchange principle and material, plays to prevent that short grained coal dust from blocking sampler barrel 4 and pipeline thereof.
Described pressure port is positioned at the top of described feeder, is convenient to the measurement to the feeder internal pressure, can prevent that again the coal dust that is fallen from blocking.
The inside of described feeder is provided with feed belt 1, and feed belt 1 can transmit coal fast, increases work efficiency.
The top of described feeder is provided with coal inlet 2, and the below of described feeder is provided with out ort 3, meets arts demand, increases work efficiency.
Described pressure port is opened pressure port with described to go out ort 3 corresponding above the following coal mouth of feeder, nearer from going out ort 3 because of pressure port, judges that chute blockage is more accurate, judges that disconnected coal is faster.
Above content only is preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
