The utility model ensures the definition of the observation window in the operation of the sealed coal feeder, solves the problem that the glass window is difficult to clean in the operation process of the sealed coal feeder, facilitates the inspection of the internal operation state in the operation process of the coal feeder, and has the characteristics of simplicity, easiness in manufacturing and remarkable cleaning effect.
Description
Technical Field
The utility model relates to the technical field of thermal power generation, coal feeders and observation window cleaning in the operation process, in particular to a dust removal device for an observation window of a sealed coal feeder.
Background
The sealed coal feeder is coal feeding equipment of a direct-fired pulverizing system of a thermal power plant, and mainly has the effects that raw coal is continuously fed to the coal mill, the inner components of a shell of the direct-fired pulverizing system are composed of a roller, a belt, a cleaning chain and the like, whether the coal feeder operates normally or not influences the stability of the pulverizing system, and the safety operation of a boiler is related, so that the monitoring of the internal operation of the coal feeder is particularly important, the internal operation condition of the coal feeder must be checked in the inspection process, the belt is damaged, deviated and slipped in the operation process of the coal feeder is checked by the sealed coal feeder mainly through an observation window, and whether the coal feeding amount is uniform or not, and whether the operation of the cleaning chain is normal or not is solved. When equipment is in fault, the glass window can visually observe the internal operation condition of the coal feeder so as to perform corresponding treatment. However, the glass window is easy to adhere to coal dust in the operation of the sealed coal feeder, so that the mirror surface of the window cannot be seen clearly, the inner operation condition of the coal feeder cannot be checked from the glass window due to long-time dust accumulation, the inside of the operation of the sealed coal feeder is sealed by positive pressure, coal dust is sprayed out in the operation of the sealed coal feeder, and the coal dust on the glass window must be manually cleaned by stopping the coal feeder, so that the continuous operation of the coal feeder is influenced.
Disclosure of Invention
The technical problem to be solved by the utility model is to provide a sealing coal feeder operation observation window cleaning device, which overcomes the problems in the prior art and has the characteristics of simplicity, easiness in manufacturing and excellent cleaning effect.
In order to solve the above-mentioned purpose, the utility model adopts the following technical scheme:
the dust removing device for the observation window of the sealed coal feeder comprises the sealed coal feeder, and the sealed coal feeder is fixedly connected with a glass observation window; the glass observation window is communicated with a sealing air pipeline of the coal feeder; a flaring flow guiding device is arranged between the sealed coal feeder and the glass observation window; the flaring flow guiding device is connected with a purging air pipeline; and a control ball valve is arranged on a pipeline between the purging air pipeline and the sealing air pipeline of the coal feeder.
Preferably, the front pipeline of the flaring flow guiding device is in slope arrangement.
Preferably, the front pipeline orifice of the flaring flow guiding device is inclined downwards.
According to the utility model, the glass window blowing air is led out from the sealing air pipeline of the coal feeder and is supplied to the glass window from the flaring guide device through the glass window blowing air pipeline, so that the blowing air pipeline is arranged at the upper part of the glass window and the front pipeline of the flaring guide device is in a slope design, the blowing angle is increased by the design of the flaring guide device, the glass window surface can be blown without dead angles, and the cleaning efficiency of the glass window is improved.
Through the technical scheme, the utility model has the following beneficial effects:
1. the blowing wind disclosed by the utility model utilizes the sealing wind of the coal feeder, is simple in device and obvious in effect, and the arrangement of the flaring flow guiding device ensures that the glass window surface can be blown without dead angles, prevents mirror area dust, ensures that the blowing pipeline is inclined downwards and is consistent with the conveying direction of raw coal, and ensures that the blocking phenomenon of the blowing pipeline occurs when the blowing wind of the blowing pipeline is not thrown.
2. The utility model has simple and flexible operation, can intermittently purge, can normally open and long purge, can adjust the purge wind pressure by the control ball valve, can adjust the purge pressure according to the mirror surface dirt and dust condition of the window, and achieves better purge cleaning effect.
3. The purging device disclosed by the utility model is simple in design, low in failure rate and low in operation risk, and the operation risk cannot be caused even if an operator forgets to turn off the purging control ball valve.
4. The purging device is put into operation, so that the monitoring efficiency of the glass window of the coal feeder is greatly improved, the risk of shutdown and cleaning of the window of the coal feeder is reduced, the labor and financial resources consumed in cleaning the observation window of the coal feeder are reduced, the operation efficiency of the coal feeder is improved, and the overhaul cost is reduced.
