The device includes a box body, an arc-shaped sealing device is fixedly connected in the box body, the arc-shaped sealing device is connected to a guiding device, and the guiding device and the blanking direction of the dried powder are arranged at a certain angle; meanwhile, a rotating system is arranged below the guiding plate.

Description

A kind of discharge sealing device

Technical field

The utility model relates to a kind of sealed discharging device, particularly the sealed discharging device that uses about a kind of suitable brown coal drying system exhaust end.

Background technology

At present, in the existing brown coal drying system, the exhaust end material is directly dropped down onto dried material on the product discharging rubber conveyer by the discharge chute usually, discharge chute is an open type, a large amount of cold airs enter drying system inside by the discharge chute, cause the drying system blow-by, increased the oxygen content of system, in the brown coal drying system because of brown coal fugitive constituent height, low, the easy spontaneous combustion of burning-point, the oxygen content increase very easily causes the brown coal spontaneous combustion even blasts dangerous the generation, and cold air carries out the temperature that drying system has reduced the drying system exhaust end, influences drying effect.In addition; aborning; dried product tends to produce a large amount of fine grained coal dusts, if these coal dusts directly fall from the discharge chute, owing to there is difference in height; tending to produce coal dust splashes; produce secondary pollution, be unfavorable for environmental protection and workshop workers'health, therefore; develop the sealed discharging device that exhaust end uses behind a kind of suitable brown coal drying, guarantee that the sealing and the security of drying system is very necessary.

The purpose of this utility model provides a kind of discharge sealing device exactly for addressing the above problem, and it is simple in structure, and cost is lower, and is easy to maintenance.

For achieving the above object, the utility model adopts following technical scheme:

A kind of discharge sealing device, it comprises casing, the arc sealing device that in casing, is connected, the arc sealing device also is connected with guider, and described guider and dried powder blanking direction are set angle; Below guide plate, be provided with simultaneously rotary system.

Described arc sealing device is an arc sealing steel plate.

Described guider is a guide plate.

Described rotary system comprises rotating shaft base, and rotating shaft base is installed on the casing, and rotating shaft is installed on the rotating shaft base, and rotating vane evenly is welded on the rotating shaft, and rotating shaft terminal is installed the spacing back-up ring of rotating shaft.

Leave the 10-20mm gap between described rotating vane and sealing device.

The utility model has the following advantages owing to adopt above technical scheme: 1, the utility model can be realized the drying system sealing, effectively stops a large amount of cold airs to enter drying system, and the oxygen content in the reduction system prevents the generation of brown coal burning and explosion danger.2, guarantee the drying system temperature inside, improve drying effect.3, the utility model prevents that effectively a large amount of coal dust of generation splashes in the workshop, prevents the secondary pollution of dust, improves workshop condition and workman's work situation greatly.5, the utility model need not external power, energy-conserving and environment-protective by the deadweight rotation.6, the utlity model has advantage such as operate steadily, easy to make, with low cost, easy to maintenance.

Description of drawings

Fig. 1 is an overall structure schematic diagram of the present utility model.

Fig. 2 is a schematic cross-section of the present utility model.

Wherein, 1. casing, 2. guide plate, 3. rotary system, 4. arc sealing steel plate, 5 rotating vanes, 6 rotating shafts, the spacing back-up ring of 7 rotating shafts, 8. rotating shaft base.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Among Fig. 1, Fig. 2, the utility model comprises casing 1, guide plate 2, rotary system 3.Casing 1 top is connected with nesting box with bolt and nut by flange, and casing 1 interior welds has arc sealing steel plate 4 and guide plate 2; Guide plate 2 has certain angle with dried material blanking direction, can make material fall into rotary system along the guide plate direction, the steel plate of its supporting role of guide plate bottom welding prevents that guide plate from using the back to produce distortion for a long time, also make be connected between guide plate and the casing more firm.Rotary system 3 comprises rotating vane 5, rotating shaft 6, the spacing back-up ring 7 of rotating shaft, rotating shaft base 8, rotating shaft base 8 are welded on the casing 1, after rotating vane 5 evenly is welded on the rotating shaft 6, the spacing back-up ring 7 of rotating shaft is installed in 6 liang of rear flank of rotating shaft, is installed in then on the both sides rotating shaft base 8, keeps the 1-2mm gap between the arc sealing steel plate 4 of rotating vane 5 after the installation and casing 1 inside, can guarantee the normal operation of rotating vane 5, can prevent that again a large amount of cold airs from entering drying system.

The utility model uses bolt and nut to be connected with nesting box by the flange on casing 1 top when mounted, and it is convenient to install.

Operation principle of the present utility model: the material that nesting box falls drops on the guide plate 2, drops on the rotating vane 5 through guide plate 2, makes rotating vane 5 rotate under the effect of material gravity, and then material is dropped on the product outfeed belt.In rotating vane 5 rotary courses, all the time guarantee that there are two rotating vanes at each arc sealing steel plate 4 place, prevented that effectively cold air from entering drying system, guaranteed the drying system sealing effectiveness, effectively reduce the drying system oxygen content, guarantee that brown coal spontaneous combustion and explosion danger can not take place in the dry run, make system safety operation.Simultaneously, guide plate 2 and rotating vane 5 have all played the effect of buffering powder falling speed, have prevented splashing of material effectively, thus the secondary pollution of having avoided dust to cause.Simultaneously, in rotating vane 5 rotary courses, guarantee that all the time there are two rotating vanes at each arc sealing steel plate 4 place, prevented that effectively cold air from entering drying system, guaranteed the drying system sealing effectiveness.

The utility model only describes with the foregoing description; the structure of each parts, the position is set and connects and all can change to some extent; on the basis of technical solutions of the utility model; all improvement and equivalents of individual component being carried out according to the utility model all should not got rid of outside protection domain of the present utility model.
