The support is used for supporting the whole equipment, the tower is mounted on the support, the lower portion of the tower is provided with a hot air port and a material inlet, the material inlet is arranged above the hot air port, an induced air port is arranged on the upper portion of the tower, the transmission device is also mounted on the support and is connected with the rotary shaft on the inner lower portion of the tower, the rotary shaft is connected with a blade shaft inside the tower, the blades are mounted on the blade shaft and include oblique blades and flat blades, the inner ends of the horizontally arranged flat blades are connected with the blade shaft, the outer ends of the flat blades extend outwardly and radially, the oblique blades are positioned below the flat blades and are in splayed arrangement on the lower portion of the blade shaft, and an included angle of 30-60 degrees is formed between each oblique blade and the blade shaft. The flash dryer for drying the silicon carbide slurry is high in dewatering capacity, high in drying speed and good in closure.
Description
Technical field
The utility model relates to technical field of drying, is specifically related to be used for the flash dryer of slurry drying.
Background technology
Pressure type steam flash dryer, dry mud coal and slurries, bark etc. are all very desirable, adopt the pressure system of enclosed, and material is by the superheated steam indirect.Because the transmission speed of particle is higher and contain impurity, drying machine is in operation brings wearing and tearing, and cause forming in the flash pipe deposition and corrosion.If the vapor (steam) temperature of transmission is lower than saturation temperature, be prone on the drying machine casing, form deposition.Need use stainless steel structure in order to prevent corrosion.Because bulk materials can not be suspended in the steam of conveying, so will be with the solid separating treatment before the charging.
Existing flash dryer exists water separation capability poor, the shortcoming that rate of drying is slow.
The utility model content
The utility model provides a kind of dry flash dryer of silicon carbide slurry that is used for, and it is a kind of stronger water separation capability that has, and rate of drying is fast, the flash dryer that is used for slurry drying that closure is good.
For addressing the above problem, the utility model adopts following technical scheme: be used for the dry flash dryer of silicon carbide slurry, be made up of support 1, transmission device 2, rotating shaft 3, blade 4 and tower body 5; Support 1 is used to support entire equipment; Tower body 5 is installed on the support 1, and its underpart is provided with hot-air mouth 8 and material inlet 9, and material inlet is above hot-air mouth, and tower body 5 tops are provided with air-vent 7; Transmission device 2 also is installed on the support 1, and transmission device is connected with the rotating shaft 3 that is located at tower body 5 interior bottoms, and rotating shaft 3 is connected with tower body 5 inner sharfs 12, and blade 4 is installed on the sharf 12, and blade 4 comprises oblique blade 10 and flat blade 11; Said flat blade 11 is horizontally disposed with and the inner sharf 12 that connects, and it is protruding that flat blade 11 outer ends are radiation; Tiltedly blade 10 is positioned at flat blade 11 belows, and tiltedly blade is the splayed setting in sharf 12 bottoms, tiltedly forms 30-60 degree angle between blade 10 and the sharf 12.
During the utility model drying slurry, integrate dry and broken, make the disposable rapid draing of slurry become powder; The heat and mass time in the dry run is short, and the thermal efficiency is high, water separation capability, and rate of drying is fast, and dry tenacity is big, and closure is good, and no dust leaks outside.The utility model volume is little, can continuity operate, and is suitable for the production needs of various scales.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of blade assembly in the utility model.
Fig. 3 is the vertical view of Fig. 2.
Symbol description among the figure: 1, support, 2, transmission device, 3, rotating shaft, 4, blade, 5, tower body, 6, heat-insulation layer, 7, air-vent, 8, hot-air mouth, 9, material inlet, 10, oblique blade, 11, flat blade, 12, sharf.
The specific embodiment
Shown in Fig. 1-3, be used for the dry flash dryer of silicon carbide slurry, form by support 1, transmission device 2, rotating shaft 3, blade 4 and tower body 5; Support 1 is used to support entire equipment; Tower body 5 is installed on the support 1, and its underpart is provided with hot-air mouth 8 and material inlet 9, and material inlet is above hot-air mouth, and tower body 5 tops are provided with air-vent 7; Transmission device 2 also is installed on the support 1, and transmission device is connected with the rotating shaft 3 that is located at tower body 5 interior bottoms, and rotating shaft 3 is connected with tower body 5 inner sharfs 12, and blade 4 is installed on the sharf 12, and blade 4 comprises oblique blade 10 and flat blade 11; Said flat blade 11 is horizontally disposed with and the inner sharf 12 that connects, and it is protruding that flat blade 11 outer ends are radiation; Tiltedly blade 10 is positioned at flat blade 11 belows, and tiltedly blade is the splayed setting in sharf 12 bottoms, tiltedly forms 30-60 degree angle between blade 10 and the sharf 12.
The hot-air mouth place is provided with heat-insulation layer 6.Sharf 12 drives blade 4 rotations with certain rotating speed, slurry is dispersed into the even fine particle of easy drying.High-temperature hot-air rotates into the tower body bottom at a high speed from hot-air mouth 8.Slurry gets in the tower body 5 from material inlet 9.After slurry got into drying machine, the high-temperature hot-air that is rotated into by the bottom impacted, and receives bump, the cutting of high speed rotational blade simultaneously, and is dry while pulverizing, and in the extremely short time, accomplishes mass transfer and diabatic process.The material that granularity is little, moisture content is low is taken out of drying machine by hot blast from air-vent, and the material that particle is bigger and moist falls by deadweight, continues quilt pulverizing and dry, thereby accomplishes even, the rapid draing of whole slurries.Tiltedly blade 10 and flat blade 11 can shred slurry, increase the surperficial contact area with high-temperature hot-air.Sharf 12 drives oblique blade 10 and flat blade 11 rotation at a high speed.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
