Abstract
The utility model discloses a RKEF technology ferronickel rotary kiln kiln hood kiln tail sealing device, including rotary kiln body and cooling tuber pipe, rotary kiln upper end is equipped with the kiln hood cover, is equipped with sealing device between kiln hood cover tip and the rotary kiln, and seal gasket and the friction ring of sealing device on by base, base constitutes, and the friction ring is on seal gasket, and seal gasket comprises the fine cloth of first layer glass, inside aluminium silicate cotton and the fine cloth of second floor glass from supreme down, and seal gasket's periphery is equipped with one deck glass fibre cloth, the utility model discloses an it is sealed that seal gasket and friction ring replace the cylinder, and sealed effect is better, and sealing device's expense to be less than the cylinder sealed, the maintenance work volume is little, the blade is changed portably, whole maintenance duration is short, single kiln be sealed reforms transform when average 5-7 days, for cylinder press the sealing, maintenance duration shortens greatly, has saved the cost, has promoted efficiency.
Description
Technical field
The utility model relates to a kind of rotary kiln, is specifically related to a kind of RKEF technique ferronickel rotary kiln end kiln tail sealing device.
Background technology
Utilize lateritic nickel ore to refine rotary kiln (RK)-mineral hot furnace (EF) technology of ferronickel for raw material smelting, be called for short RKEF technique.RKEF mature technology, equipment are simple and easy to control, production efficiency is high, accept by increasing enterprise.
Cylinder of rotary kiln is certain angle of inclination, rotary kiln is caused easily to have the displacement of trace in the axial direction, rotary kiln and other equipment are caused to produce certain interval being connected sealing place, there is gas leak phenomenon, therefore, add exhaust blower load, improve grog heat energy trumpet and production cost, meanwhile, cause dust to overflow, pollute production environment.Existing rotary kiln sealing counting uses cylinder seal device, because kiln end temperature is generally at 200 to 300 DEG C, the tracheae of cylinder seal matched with devices is at high temperature easy to aging, cylinder seal package unit needs compressed air to provide power, cost and production run cost higher, more the cycle of scavenge trunk needs 5 ~ 6 days, causes very large puzzlement to the production of rotary kiln.
Utility model content
For the problems referred to above, the utility model provides a kind of RKEF technique ferronickel rotary kiln end kiln tail sealing device, its object is to: overcome deficiency of the prior art, provides a kind of structure simple, good airproof performance, safe and reliable sealing device.
Technical solution of the present utility model:
A kind of RKEF technique ferronickel rotary kiln end kiln tail sealing device, comprise rotary kiln body and cooling duct, it is characterized in that: described rotary kiln upper end is provided with kiln head cover, sealing device is provided with between described kiln head cover end and rotary kiln, described sealing device is made up of the gasket seal on base, base and drag ring, described drag ring is on gasket seal, described gasket seal is made up of ground floor glass-fiber-fabric, inner aluminium silicate wool and second layer glass-fiber-fabric from bottom to up, and the outer of described gasket seal is arranged with layer of glass fiber fabric.
The thickness of described ground floor glass-fiber-fabric is 1.4mm.
The thickness of described second layer glass-fiber-fabric is 1.4mm.
Described drag ring material is spring steel after heat treatment.
Described drag ring and gasket seal surface smear have carboxylic ester paint, can strengthen lubrication between the two.
The beneficial effects of the utility model:
The utility model substitutes cylinder seal by gasket seal and drag ring, sealing effectiveness is better, and the expense of sealing device is lower than cylinder seal, maintenance load is little, and blade exchanging is easy, overall maintenance time is short, single kiln seal reconstruction mean time 5 ~ 7 days, relative to cylinder press seal, maintenance time shortens greatly, provide cost savings, improve efficiency.
Accompanying drawing explanation
Fig. 1: the utility model structural principle schematic diagram.
Fig. 2: the utility model gasket seal schematic cross-section.
Wherein: 1 rotary kiln body 2 cooling duct 3 base 4 gasket seal 4-1 ground floor glass-fiber-fabric 4-2 aluminium silicate wool 4-3 second layer glass-fiber-fabric 4-4 glass-fiber-fabric 5 drag ring 6 kiln head cover.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further:
As shown in Fig. 1 to 2, a kind of RKEF technique ferronickel rotary kiln end kiln tail sealing device, comprise rotary kiln body 1 and cooling duct 2, described rotary kiln body 1 upper end is provided with kiln head cover 6, sealing device is provided with between described kiln head cover 6 end and rotary kiln body 1, described sealing device is by base 3, gasket seal 4 on base 3 and drag ring 5 are formed, described drag ring 5 is on gasket seal 4, described gasket seal 4 is from bottom to up by ground floor glass-fiber-fabric 4-1, inner aluminium silicate wool 4-2 and second layer glass-fiber-fabric 4-3 forms, the thickness of described ground floor glass-fiber-fabric 4-1 is 1.4mm, the thickness of described second layer glass-fiber-fabric 4-3 is 1.4mm, described the outer of gasket seal 4 is arranged with layer of glass fiber fabric 4-4, gasket seal 4 is the asbestos cloth of heat resisting and pressure resisting, gasket seal 4 at least can work 1 year at high temperature 200 DEG C.
In rotary kiln running, drag ring 5 fits tightly with gasket seal, it is consumable accessory, drag ring 5 material is spring steel after heat treatment, in order to improve the service life of drag ring 5, at drag ring 5 with gasket seal 4 joint place welding wearing plate, carboxylic ester paint can be had at drag ring 5 and gasket seal 4 surface smear simultaneously, lubrication between the two can be strengthened.
To sum up, the utility model accomplishes the end in view.
Claims (5)
