Abstract
The utility model discloses a material return feeder, which comprises a body, a feeding port, a discharging port, a partition wall and a material return loosening air pipe. The feeding port and the discharging port are respectively arranged on the body and at two ends of the material return loosening air pipe, one end of the partition wall is fixed at the top of the body, the other end of the partition wall is suspended in the body, and the material return loosening air pipe is fixed at the bottom of the body. After modification, even when pressure of a furnace cavity drops abruptly, materials in the return feeder can not flood into the furnace cavity so that forced shutdown is avoided, production cost is lowered, and potential danger in production is eliminated.
Description
Technical field
The utility model relates to a kind of recirculating fluidized bed and use material returning device, in particular a kind of material material returning device.
Background technology
Unburnt high-temperature material returns the burner hearth internal combustion through discharging opening in the recirculating fluidized bed after material returning device is caught; Gravity that the solid accumulation height forms in the material returning device and the furnace pressure proportion relation in the burner hearth; When being slightly larger than furnace pressure, material flows into burner hearth naturally in the material returning device when great.When furnace pressure descended suddenly, material can pour in burner hearth, the primary air fan surge, and boiler is compelled blowing out.
The utility model content
The utility model purpose: the utility model provides a kind of material material returning device, solves recycle stock through the improvement to partition wall and the loosening airduct of returning charge and pounces in a large number into burner hearth, guarantees safe operation of the boiler.
Technical scheme: the utility model realizes through following technical scheme, and the utility model comprises that body, charging aperture, discharging opening, partition wall and returning charge become flexible airduct; Wherein: charging aperture and discharging opening are arranged at respectively on the body, and charging aperture and discharging opening are positioned at the two ends of the loosening airduct of returning charge, and an end of partition wall is fixed on the top of body, and the other end of partition wall is unsettled in body, and the loosening airduct of returning charge is fixed on the bottom of body.
The loosening airduct of said returning charge is provided with the feed end mouth of pipe and the discharge end mouth of pipe, and the caliber of the said discharge end mouth of pipe is greater than the caliber of the feed end mouth of pipe.
Beneficial effect: the utility model is compared prior art and had the following advantages: when furnace pressure descended suddenly, material can not pour in burner hearth to the utility model material returning device yet in the material returning device after transforming; Avoid compelled blowing out, reduce production costs, eliminated the potential safety hazard in producing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Embodiment in the face of the utility model elaborates down; Present embodiment is being to implement under the prerequisite with the utility model technical scheme; Provided detailed embodiment and concrete operating process, but the protection domain of the utility model is not limited to following embodiment.
As shown in Figure 1, present embodiment comprises that body 1, charging aperture 2, discharging opening 3, partition wall 4 and returning charge become flexible airduct 5; Wherein: charging aperture 2 is arranged at respectively on the body 1 with discharging opening 3; Charging aperture 2 is positioned at the two ends that airduct 5 is become flexible in returning charge with discharging opening 3; One end of partition wall 4 is fixed on the top of body 1, and the other end of partition wall 4 is unsettled in body 1, and the loosening airduct 5 of returning charge is fixed on the bottom of body 1.
The loosening airduct 5 of returning charge is provided with the feed end mouth of pipe 6 and the discharge end mouth of pipe 7, and the caliber of the discharge end mouth of pipe 7 is greater than the caliber of the feed end mouth of pipe 6, and the spacing of the adjacent discharge end mouth of pipe 7 is greater than the spacing of the adjacent feed end mouth of pipe 6.
