Abstract
The utility model relates to a calcium spraying desulphurization metering power feeding device. In the system operation process, an ordinary feeding device often has the faults that impeller seizure which easily occurs in the occurrence of large grains or hardened powder blocks can cause device fault and shutdown, and can influence the continuous operation of a desulphurization system; the shaft end sealing performance of a rotating shaft of the power feeding device is poor, and the outer leakage of limestone powder from the shaft end and the like can be caused. The calcium spraying desulphurization metering power feeding device consists of a case (1), a clamp prevention baffle plate (2), a motor (3), a frequency converter (4) and a positive rotation and reverse rotation switching device (5), wherein the clamp prevention baffle plate (2) is arranged in the case, the motor (3) is arranged on the right side above the case, the motor (3) is provided with the frequency converter (4) and the positive rotation and reverse rotation switching device (5), the motor is linked with a speed reducer (6), the speed reducer drives a chain to drive a rotating shaft (7), and the rotating shaft (7) is provided with an impeller (8). The product is used for a calcium spraying desulphurization system in a circulating fluidized bed boiler.
Description
Technical field:
The utility model relates to a kind of instantly measure device, is specifically related to a kind of calcium injection and desulfurization and measures to the powder device.
Background technology:
The used agstone of calcium injection and desulfurization system in the circulating fluid bed boiler through to the metering of powder device, is sent agstone into boiler malleation burner hearth by the air-transport system of agstone warehouse bottom.General charging gear is normal in system's running, and following fault takes place: run into bigger particle or occur impeller easily during the powder agglomates that hardens stuck, cause plant failure to shut down, influence the continuous operation of desulphurization system; Shaft end seal to powder device turning cylinder is poor, when system moves, gives in the powder device case and can scurry into a certain amount of gas, causes that agstone is scurried etc. outside axle head.
Summary of the invention:
The purpose of this utility model provides a kind of calcium injection and desulfurization and measures to the powder device, can improve anti-sticking ability and the sealing of metering to the powder device, realizes that the desulfurizing agent agstone accurately measures, feeds uniformly and stably defeated powder system.
Above-mentioned purpose realizes by following technical scheme:
Calcium injection and desulfurization measures to the powder device, its composition comprises: housing, be provided with the anti-sticking baffle plate in the described housing, there is motor in described housing upper right side, described motor is equipped with frequency converter and rotating switching device shifter, described motor linkage reductor, described reductor drives the chain drive turning cylinder, and described turning cylinder is equipped with impeller.
Described calcium injection and desulfurization measures to the powder device, and described turning cylinder comprises the smooth mirror surface end cap at two ends, on the described smooth mirror surface end cap air inlet pipe is housed, and spring is equipped with in the described smooth mirror surface end cap end cap outside.
The beneficial effects of the utility model:
1. the utility model adopts the elasticity anti-sticking baffle plate that tilts to rotation direction at the charging aperture place, is equipped with the rotating switching device shifter of electric control system, and the plant failure that larger particles or the stuck impeller of powder agglomates that hardens caused when prevention was given powder is continuously shut down.
2. the utility model adopts frequency converter to make the rotor frequency control, by control system according to the signal feedback of coal feeder of boiler coal-supplying amount to controlling powder-feeding amount to the powder device, by regulating rotating speed, realize that by rotating shaft and impeller accurately the control agstone is given output, satisfy the desulphurization system needs, guarantee that agstone accurately measures, feed defeated powder system uniformly and stably.
3. the utility model adopts the turning cylinder axle end sealing device, strengthens shaft end seal, prevents that defeated powder wind from carrying powder and scurrying outward, loses desulfurizing agent and causes environmental pollution.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is vertical views of accompanying drawing 1.
The specific embodiment:
Embodiment 1:
Calcium injection and desulfurization measures to the powder device, its composition comprises: housing 1, be provided with anti-sticking baffle plate 2 in the described housing 1, there is motor 3 in described housing 1 upper right side, described motor 3 is equipped with frequency converter 4 and rotating switching device shifter 5, described motor 3 linkage speed reducers 6, described reductor 6 drives chain drive turning cylinder 7, and described turning cylinder 7 is equipped with impeller 8.
Embodiment 2:
Above-mentioned calcium injection and desulfurization measures to the powder device, described turning cylinder 7 two ends are furnished with smooth mirror surface end cap 9, replace simple matched in clearance with the smooth mirror surface friction, on the described smooth mirror surface end cap end cap 9 air inlet pipe 10 is housed, use compressed air to prevent that powder from entering the between centers crack, guarantee not to be subjected to powder to influence continuous operation, strengthen service life, described smooth mirror surface end cap end cap 9 outsides are equipped with spring 11 and are used for pretension smooth mirror surface end cap.It is poor so to have solved shaft end seal, the problem that powder is scurried outward.
Claims (2)
