Abstract

The utility model relates to a coal ash making fiber air-cooling device, realized by the following technical art: this device comprises a making fiber wobbler, a chief axis, a rolling bearing, an air-supply line, the rear end of the making fiber wobbler and one end of the chief axis is enclosed and connected, the outer ring of the rolling bearing is fixed on the other end of the chief axis, the air-supply line is closely arranged in the inner ring of the rolling bearing. The characteristics lay in that The utility model can create appropriate temperature for coal ash making fiber, thereby making the already-made coal ash fiber quite thin and producing coal ash fiber with diameter less than 5 um and the dose rate of slag lower than 5 percent; high rate air flow ejaculates the fumarole of the wobbler, having stretching effect for fiber, thereby creating more thin fiber and better separating the slag ball; by controlling the forced draft of the forced air, The utility model can realize controlling the temperature of the wobbler, thereby satisfying different art demands of coal ash making fiber of various ingredients, simultaneously guaranteeing the service life of the wobbler with 200 hours on average.

Description

The air-cooled mechanism of preparing fiber by fly ash

Technical field

The utility model relates to the fine device of mineral fibre system, relates in particular to the air-cooled mechanism of preparing fiber by fly ash.

Background technology

When mineral fibre became fine on the fine machine of system, because the general temperature of its roasting body is all higher, the episome in the roasting body can corrode the roller head, causes the damage of roller head, so will cool off making fine roller.Usually the method for cooling of the fine machine of coal ash fiber system is the method for using the fine machine of general mineral fibre system, promptly is with the hollow roll head of circulating water flow by high speed rotating.This method is to slag, and the rock type fiber is suitable for, but unsatisfactory to the production of coal ash fiber.This is because flyash has different characteristics with slag, rock.The flyash acidity quotient is relatively large, and free iron content is low than the person relatively, and the viscosity of its roasting body is bigger, becomes fine temperature than higher.Water-cooling method will cause the cooling of roller head excessive, and consequently bake body and become fine temperature too low, be comparatively to be fit to for the one-tenth fibre that becomes the relatively low slag of fine temperature, rock type mineral fibre, coal ash fiber one-tenth is then returned make fibre thickening, the slag ball increases.Simultaneously, relatively flyash becomes fine required suitable temp and the temperature that descends, to reducing to bake body pair roller head erosion action effect and not obvious.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, designs the fine wind cooling method device of coal ash fiber system that a kind of tailored powder coal ash becomes the required suitable temp of pricker.It is realized by following technical scheme:

Comprise the fine roller head of system, main shaft, rolling bearing and blast pipe, rear end and main shaft one end of making fine roller head are tightly connected, and housing washer is fixed on main shaft the other end, and the blast pipe close-fitting is at rolling bearing inner ring.

The periphery of making fine roller head front end face is evenly equipped with some wind hole.

Rear-end of spindle connects a bearing support, and the outer ring close-fitting of rolling bearing is connected with step cover in the bearing support outside in this bearing support.

The beneficial effects of the utility model are: 1) utilize the utility model device can obtain the fine required suitable temp of tailored powder coal ash system, thereby make fine coal ash fiber fineness thinner, can produce diameter less than 5 μ m coal ash fibers, its slag-containing rate amount is lower than below 5%; 2) high velocity air sprays from the pore of roller head front end, and fiber is had stretching action, thereby the fiber that is obtained is thinner, and is better to the separating effect of slag ball; 3) by controlling compressed-air actuated pressure, can realize pair roller head temperature controlling, thereby satisfy the processing requirement of heterogeneity powdered coal ash system fibre, also guarantee the work-ing life of roller head simultaneously, can reach about 200 hours usually with regard to airshed.

Description of drawings

Fig. 1 is the structural representation of the utility model one embodiment.

Among the figure, the 1st, blast pipe, the 2nd, rolling bearing, the 3rd, main shaft, the 4th, make fine roller head, the 5th, wind hole, the 6th, bearing support, the 7th, step cover, the 8th, airduct.

Embodiment

See also Fig. 1, the utility model device mainly is made up of the fine roller head 4 of system, main shaft 2, rolling bearing 3, blast pipe 1, airduct 8 and air compressor machine 9.Make on the periphery of fine roller head 4 front end faces and be evenly equipped with 6 wind holes 5, an end of its rear end and main shaft 2 is tightly connected.The other end of main shaft 2 connects a bearing support 6, and rolling bearing 3 outer ring close-fittings are in this bearing support, and bearing support 6 outsides are connected with step cover 7.The blast pipe close-fitting is at the inner ring of rolling bearing 2, and airduct 8 one ends connect blast pipe one end and connect air compressor machine.On near the airduct 8 at blast pipe place, an air intake valve 10 is installed, also air valve 1 can be arranged on the blast pipe 1.

During work, make fine roller head 4 and constantly rotate, blast pipe does not rotate.Open air intake valve 10, pressurized air in the air compressor machine 9 enters main shaft 3 through airduct 8, valve 10, blast pipe 1, and ejects through making 6 uniform wind holes 5 of fine roller head 4 front end faces periphery, the part heat on 4 on the fine roller of system is taken away it is cooled.Make the temperature on the fine roller head of system drop to a suitable temp by the pressure of adjusting air compressor machine 9 or the aperture (airshed) of regulated valve 10, guarantee that the coal ash fiber that is obtained reaches certain fineness requirement.When high velocity air sprays simultaneously, fiber there is stretching action from the wind hole of roller head front end, makes the fiber that is obtained thinner, can produce the coal ash fiber of diameter less than 5 μ m, better to the separating effect of slag ball.

Claims
