Abstract
The utility model discloses a belt feeder observation window device that can blow and sweep, including installing the observation window on annular window cover, annular window cover be hollow structure, inside is the air vent, annular window cover's inner wall is equipped with a plurality of nozzles in the inboard of observation window, the air vent of nozzle and annular window cover be linked together, annular window cover's air vent is linked together through air duct and the sealed wind pipeline of feeder, air duct on be equipped with the valve, the inboard of observation window is equipped with cleaning device. The utility model discloses utilize the wind in the sealed air duct of feeder to blow down from the nozzle blowout of annular window wrap inner wall to the side surface in the observation window constantly sweeps at the feeder during operation, thereby prevents that the buggy from adhering to the surface at the observation window, combines to clean the brush simultaneously and cleans the surface of observation window, can realize cleaning without shutting down.
Description
Technical Field
The utility model relates to a belt feeder observation window device that can blow and sweep.
Background
At coal fired power plant, the belt feeder is after sending the coal for a long time, and its observation window can be covered by the buggy, and operating personnel and maintainer can't judge the inside actual behavior of equipment like this to can influence the safe and reliable operation of equipment, at this moment, need to shut down the equipment usually, then manually clean the observation window, start the operation again after resuming observation function, this has just influenced production efficiency greatly, can't satisfy the production requirement.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model provides a belt feeder observation window device that can blow sweeps has effectively solved the problem pointed out in the background art.
The utility model adopts the technical proposal that:
the utility model provides a belt feeder observation window device that can blow sweep, is including installing the observation window on annular window cover, annular window cover be hollow structure, the inside air vent that is, the inner wall of annular window cover is equipped with a plurality of nozzles in the inboard of observation window, the air vent of nozzle and annular window cover be linked together, the air vent of annular window cover is linked together through air duct and the sealed wind pipeline of feeder, air duct on be equipped with the valve, the inboard of observation window is equipped with cleaning device.
Preferably, the cleaning device includes a rotating shaft vertically disposed at a central portion inside the observation window, and a cleaning brush fixed in a radial direction of the rotating shaft, and the rotating shaft is capable of rotating around an axis of the rotating shaft by being driven by a motor.
Preferably, the number of the nozzles is at least 4, the nozzles are uniformly distributed on the inner wall of the annular window sleeve in a circumferential mode, and the opening of each nozzle faces the center of the observation window.
The utility model has the advantages that:
1. the air in the sealing air pipeline of the coal feeder is sprayed out from the nozzles on the inner wall of the annular window sleeve, so that the inner side surface of the observation window is swept constantly when the coal feeder works, the pulverized coal is prevented from being attached to the surface of the observation window, and meanwhile, the surface of the observation window is swept by combining with a sweeping brush, so that non-stop sweeping can be realized;
2. the air quantity sprayed out by the nozzle can be adjusted through the valve, so that different environmental requirements can be met;
3. the cleaning brush is driven by the motor when necessary, and is very convenient to use.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following detailed description of specific embodiments thereof, which is illustrated in the accompanying drawings.
Example 1
As shown in fig. 1, a belt feeder observation window device that can blow and sweep, including installing observation window 2 on annular window wrap 1, annular window wrap 1 be hollow structure, inside is the air vent, the inner wall of annular window wrap 1 is equipped with a plurality of nozzles 3 in the inboard of observation window 2, nozzle 3 be linked together with the air vent of annular window wrap 1, the air vent of annular window wrap 1 is linked together through air duct 4 and feeder sealed air duct 5, air duct 4 on be equipped with valve 6, the inboard of observation window 2 is equipped with cleaning device 7.
The cleaning device 7 comprises a rotating shaft 71 vertically arranged at the central part of the inner side of the observation window 2 and a cleaning brush 72 fixed on the radial direction of the rotating shaft 71, wherein the rotating shaft 71 can be driven to rotate by a motor by taking the axis of the rotating shaft 71 as the center.
The number of the nozzles 3 is at least 4, the nozzles are uniformly distributed on the inner wall of the annular window sleeve 1 in a circumferential mode, and the opening of each nozzle 3 faces the center of the observation window 2.
The utility model discloses a theory of operation:
when the coal feeder operates, the valve 6 can be opened or closed as required, when the valve 6 is opened, air in the coal feeder sealing air pipeline 5 is sprayed out from the nozzle 3 after passing through the air pipeline 4, the inner side surface of the observation window 2 is swept, and the air volume can be adjusted by the valve 6.
When stubborn coal dust adheres to the inner side surface of the observation window 2 and the nozzle 3 cannot blow the stubborn coal dust off, the cleaning brush 72 can be started to clean, and the light transmittance of the observation window 2 is guaranteed.
Finally, it should be noted that the above-mentioned embodiments are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
