Description
Technical field
The utility model relates to a kind of material blanking tube, particularly a kind of Novel belt machine material blanking tube, belongs to power plant soot load transfer device technical field.
Background technology
The fortune coal measures system of current domestic coal-fired station, belt conveyer (abbreviation belt feeder) is generally adopted to transport coal-fired load transfer device as to boiler room, due to arrangement technology requirement, need by the repeatedly transhipment of belt feeder at power plant's on-site, fire coal could be transported to and be positioned at high-order power plant boiler room run coal bin, at each transfer office, installing belt feeder material blanking tube is all needed to carry the transhipment of fire coal to make every bar belt feeder complete.
The belt feeder material blanking tube of existing coal-fired station, mostly adopt the square pipe of steel plate processing and fabricating, different sizes is configured respectively by different belt feeder width, the Connecting groups lower belt feeder that closes completes coal-fired transhipment, because in transport process, belt feeder exists drop, the sectional area of square pipe belt feeder material blanking tube is larger, the air carried secretly in the coal fallen and coal dust is many, carried by air secretly to overflow the situation of flying upward serious, become the first dust pollution source of power plant fortune coal measures system, simultaneously because material blanking tube sectional area is large, in pipe, coal stream misaligns even deflection, impact material feeding belt feeder and produce side impacting force, cause material feeding belt offset track, affect the normal operation of belt safety.
Utility model content
The purpose of this utility model is, provide a kind of Novel belt machine material blanking tube, it can suppress flying upward of coal dust, alleviates dust pollution, reduces simultaneously and even eliminates the coal-fired side impacting force to material feeding belt feeder, making the running safety and reliability of belt feeder.
The technical solution of the utility model: a kind of Novel belt machine material blanking tube, comprise flange, straight tube body, inclined tube body, inlet point and discharging opening, straight tube body is fixedly installed on flange, straight tube body and inclined tube body are four sides type body, one end of straight tube body is fixedly connected with one end of inclined tube body, and inlet point is arranged on the straight tube body other end, and discharging opening is arranged on the inclined tube body other end, inlet point is square openings, and discharging opening is rectangular aperture.The shape of discharging opening is rectangle, and the sectional area of inclined tube body is reduced gradually, and the sectional area of material blanking tube also reduces thereupon, inhibits flying upward of coal dust, and reduces and even eliminate the coal-fired side impacting force to material feeding belt feeder.
In aforesaid this Novel belt machine material blanking tube, the length of long sides of discharging opening is 2 times of length of short sides.The area of discharging opening reduces, and is the half of existing discharging opening area, through calculating, can ensure coal-fired by blocking of not putting up a bridge during material blanking tube.
In aforesaid this Novel belt machine material blanking tube, the angle of inclined tube body and horizontal direction is 60 °.Inclined tube body is set from the horizontal by 60 ° of angles, can makes the coal-fired impulsive force to material feeding belt feeder and material blanking tube all in reasonable tolerance range.
Compared with prior art, the belt feeder material blanking tube that the utility model provides is the material blanking tube of variable section, the shape of discharging opening is rectangle, the sectional area of discharge outlet is minimum, for the half of square pipe material blanking tube sectional area, the reduction of material blanking tube sectional area, inhibit flying upward of coal dust, alleviate dust pollution, reduce simultaneously and even eliminate the coal-fired side impacting force to material feeding belt feeder, make the running safety and reliability of belt feeder, the utility model design is ingenious, structure is simple, implementation cost is lower, actual effect is obvious, be adapted at coal-fired station to apply.
