Abstract
The utility model discloses a dewatered sludge screening crusher. The dewatered sludge screening crusher is characterized in that a three-dimensional screen (2) is arranged above a sludge inlet (1), a primary collecting bucket (3) is arranged below the three-dimensional screen (2), a discharge outlet of the three-dimensional screen (2) is arranged above a crushing mechanism (4), a secondary collecting bucket (5) is arranged below the crushing mechanism (4), an outlet of the secondary collecting bucket (5) is connected with an inlet of a return conveyer (6), and an outlet of the return conveyer (6) is connected to the sludge inlet (1). The crusher can enable dewatered sludge meeting the requirement of particle sizes of particles capable of entering a furnace to pass through, dewatered sludge with the particle sizes larger than the particle sizes of the particles capable of entering the furnace are required to be crushed and then can pass through the crusher after meeting the requirement of the particle sizes of particles capable of entering the furnace, so that the incineration effect of an incinerator can be improved.
Description
Technical field
The utility model relates to dewatered sludge incineration technology field, the equipment of the broken dewatered sludge of screening before specifically a kind of dewatered sludge burns.
Background technology
Sewage biochemical treatment association mud, Treatment of Sludge are disposed and improperly may be caused bigger harm to environment and the mankind and animal health.The burning method disposing sludge be prone to realize the final goal of Treatment of Sludge-subtract appearanceization, stabilisation, innoxious.Mud is fit to adopt fluidized combustion.Adopt recirculating fluidized bed sludge incinerator burning and drying mud, incinerator has requirement to going into stove dewatered sludge grain diameter.Too thick, influence fluidization uniformity, can't participate in circulation, can not set up dilute-phase zone fluidized state in the stove, end slag treatment system is brought very big problem.Too thin, also have little time completing combustion and just taken out of cyclone separator by flue gas, cause the flying dust heat loss to increase.
Summary of the invention
The purpose of the utility model is exactly the deficiency to above-mentioned prior art, provides a kind of and can make into the satisfactory dewatered sludge screening crusher in stove dewatered sludge particulate material footpath.
The technical scheme that the utility model adopts is following:
A kind of dewatered sludge screening crusher; It is characterized in that above the mud import, being provided with three-dimensional sieve; The below of three-dimensional sieve is provided with collection bucket one time, and the discharging opening of three-dimensional sieve is arranged at the top of crushing mechanism, and the below of crushing mechanism is provided with the secondary collection bucket; The outlet of secondary collection bucket connects the import of returning charge conveyer, and the outlet of returning charge conveyer is connected to the mud import.
Concavo-convex pair of roll of employing level in the said crushing mechanism.
Said returning charge conveyer is a vertical screw type conveyer.
The beneficial effect of the utility model has:
This equipment can make the dewatered sludge that meets into the requirement of stove grain diameter pass through, and needs through fragmentation greater than the dewatered sludge of going into the requirement of stove grain diameter, passes through after meeting the requirement of stove grain diameter again, has improved the burning effect of incinerator.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further:
As shown in Figure 1, the utility model is provided with three-dimensional sieve 2 above mud import 1, and the below of three-dimensional sieve 2 is provided with collection bucket 3 one time.The discharging opening of three-dimensional sieve 2 is arranged at the top of crushing mechanism 4, and the below of crushing mechanism 4 is provided with secondary collection bucket 5, and the outlet of secondary collection bucket 5 connects the import of returning charge conveyer 6, and the outlet of returning charge conveyer 6 is connected to mud import 1.Can concavo-convex pair of roll of employing level in the crushing mechanism 4 come the bulky grain dewatered sludge of crushing and screening, crushing effect is good.Returning charge conveyer 6 can adopt vertical screw type conveyer.
The course of work of the utility model is following:
The dewatered sludge that drying machine is discharged is carried from mud import 1 and is got into the dewatered sludge screening crusher.Dewatered sludge drops on adjustable three-dimensional sieve 2 and sieves, and sieves the particle dewatered sludge behind a collection bucket 3, discharges through its outlet; The crushing mechanism 4 that the bulky grain dewatered sludge that can not sieve rolls into concavo-convex pair of roll of employing level carries out fragmentation.Particle dewatered sludge after the fragmentation falls into returning charge conveyer 6 after secondary collection bucket 5 is collected; Returning charge conveyer 6 will be after fragmentation particle dewatered sludge vertical transport; Dropping on adjustable three-dimensional sieve on 2 through inclined tube through the returning charge mouth sieves once more; So circulation meets into the stove requirement until whole dewatered sludge grain diameters.
Other undeclared part that the utility model relates to is identical with prior art.
Claims (3)
