Abstract
The utility model relates to a decomposing furnace material scattering device and belongs to the field of cement production equipment. The decomposing furnace material scattering device comprises a decomposing furnace top and a decomposing furnace material loading pipe and further comprises a fixed mount and material scattering plates; the fixed mount has a frame-shaped structure; the material scattering plates are disposed inside the fixed mount in a stepped and staggered manner; the fixed mount is disposed on one side of the decomposing furnace top and the decomposing furnace material loading pipe and tilts towards the decomposing furnace material loading pipe; and the downward shadow of the fixed mount completely covers the downward shadow of the decomposing furnace material loading pipe. The decomposing furnace material scattering device has a simple structure, is easy to use, performs primary separation of material through the material scattering plates during falling of the material and realizes thorough separation of the material in combination with three wind flows, thereby guaranteeing full contact between the material and high temperature smoke in a decomposing furnace, improving heat exchange efficiency and preventing waste of heat.
Description
Technical field
The utility model relates to a kind of dore furnace material-strewing device, belongs to the cement manufacture plant field.
Background technology
In the dore furnace of general band precombustion chamber, the raw material that get into dore furnace all are the tremie pipes by the whirlwind tube, fall in the dore furnace from the top of precombustion chamber.Raw material in falling into precombustion chamber after, generally all is it to be dispelled by the tertiary air that gets into precombustion chamber so that fully contact, carry out heat exchange efficiently with high-temperature flue gas in the stove.
But because raw material are when getting into dore furnace, the adhesiveness between the raw material particle, and the inhomogeneities during blanking make raw material be difficult to evenly disperse.Particularly when blanking was inhomogeneous, big strand raw material will directly be fallen the dore furnace bottom together fast along with the thermal current of coming from tertiary-air pipe.And fully do not contact with high-temperature flue gas, make raw material not carry out due heat exchange, the temperature of raw material is not elevated to the decomposition temperature of calcium carbonate, thereby resolution ratio does not reach the requirement of regulation.Influenced the ability of dore furnace.Simultaneously, because flue gas does not carry out heat exchange with raw material, therefore, caused the waste of heat.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: provide a kind of and can overcome above-mentioned defective, ability is separation of material fully, avoids the dore furnace material-strewing device of heat waste.
The utility model solves the technical scheme that its technical problem adopted: the dore furnace material-strewing device; The tremie pipe that comprises dore furnace top and dore furnace top; It is characterized in that: also comprise fixed mount and spreading plate, fixed mount is a closed-in construction, and the spreading plate is stepped to be crisscross arranged in fixed mount inside; The spreading plate is positioned at the below of tremie pipe, and the downward projection section of fixed mount covers the downward projection of tremie pipe.
The downward projection of fixed mount covers the downward projection of tremie pipe, guarantees that the material that tremie pipe falls all can contact with the spreading plate, guarantees feed separation efficient.Spreading plate spreading plate is stepped to be crisscross arranged in fixed mount inside, falls and can repeatedly contact with the spreading plate at material, and its separating effect is better.And fixed mount is arranged on a side of dore furnace top, tremie pipe, and fixed mount tilts to the tremie pipe place, makes itself and projected area on the vertical plane of tertiary air flow direction very little of to reduce the mobile resistance of tertiary air.
The beneficial effect that the utility model had is: make simple; Easy to use; When material falls, at first material is carried out initial gross separation, cooperate the thorough separation of material of tertiary air again, guarantee that material fully contacts with high-temperature flue gas in dore furnace through the spreading plate; Improve heat exchange efficiency, avoid heat waste.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1, tremie pipe; 2, dore furnace top; 3, fixed mount; 4, spreading plate.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1, described dore furnace material-strewing device comprises dore furnace top 2 and tremie pipe 1; Also comprise fixed mount 3 and spreading plate 4; Fixed mount 3 is a closed-in construction, spreading plate 4 stepped being crisscross arranged in fixed mount 3 inside, and fixed mount 3 is arranged on a side of dore furnace top 2, tremie pipe 1; And fixed mount 3 tilts to tremie pipe 1 place, and fixed mount 3 downward projections cover the downward projection of tremie pipe 1 fully.Angle between fixed mount 3 and the spreading plate 4 is 30 °, neither influences the effect that material falls can play again good bump material.
When material falls through tremie pipe 1; With tentatively disperseed behind spreading plate 4 contact impacts, cooperate tertiary air again, do the action that rotation is fallen with tertiary air; High-temperature flue gas abundant and that dore furnace is interior carries out heat exchange; Reach the material temperature needs fast, save the energy, have good economic benefit and social benefit.
