Description
Technical field
The utility model relates to a kind of novel direct-type fluorite rotary drying machine.
Background technology
At present, being used for the dry dryer of fluorite is the indirect type rotary dryer, and this drier fluorite and hot blast separate through layer of metal, and heat reaches material by metallic walls.Because wet fluorite is mobile relatively poor, wet fluorite sticks on the metallic walls easily, causes heat transfer coefficient to reduce greatly, can cause stammerer when serious, influences the carrying out of dry run.In addition, because the indirect type rotary drying machine is compared with the direct-type rotary drying machine, the thermal efficiency is relatively low, so under equivalent production capacity, the indirect type rotary drying machine is bigger than direct-type rotary drying machine device, shared plant area is big.
Direct-type rotary drying machine lifting blade is continued to use the structure of L type always, and lifting blade is distributed on the cylindrical shell circumference, and is in spiral distribution to L type lifting blade along drum shaft.Traditional dryer lifting blade distributes shown in figure one, and the existence of the dryer of L type lifting blade owing to wind-tunnel is housed, and inefficiency, material are difficult to oven dry, heat exchange is poor.If improve the output of dryer, often cause that discharging moisture improves, exceed the control index, so after output reaches certain numerical value, be difficult to improve again.Tradition dryer ineffective main cause have following some:
1, existence wind-tunnel from front to back.The L type lifting blade of same specification from front to back is housed in the drier body, makes the wind-tunnel that exists in the cylindrical shell from front to back, the portion of hot air has little time exchange, directly drains.The hot-air of high temperature has not only caused heat waster, and cloth bag has been caused infringement, has reduced the service life of cloth bag.
2, material decentralization on the cylindrical shell cross section is low.Lifting blade in the dryer is the design of L type, and L type lifting blade top is level and smooth cross section, and wet fluorite is when lifting blade scatters, and is less with the contact area of hot blast.
3, the time of contact of material and hot blast is short.Traditional dryer only is provided with lifting blade at the dryer middle part, and the dryer postmedian does not have any lifting blade, causes material to arrive postmedian and is stacked into later on together, causes caking easily.And material only surface contacts with hot blast, and the thermal efficiency is reduced greatly.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: provide a kind of and can overcome above-mentioned defective, can improve heat exchange, drying efficiency, and can prevent the novel direct-type fluorite rotary drying machine of material caking.
The utility model solves the technical scheme that its technical problem adopted: described novel direct-type fluorite rotary drying machine; Comprise direct-type fluorite rotary drying machine; It is characterized in that: the cylindrical shell of direct-type fluorite rotary drying machine comprises preheating zone, dry section, little district, guide district and the discharge zone raised that connects successively; And preheating zone, dry section, little raising in district and the discharge zone are provided with lifting blade, and the preheating zone front end connects the spiral feed zone of direct-type fluorite rotary drying machine.
Evenly be provided with polylith zigzag L type lifting blade on the cylindrical shell circumference of described preheating zone.
Evenly be provided with polylith zigzag L type lifting blade and board-type lifting blade on the cylindrical shell circumference of described dry section, and board-type lifting blade in interval between per two zigzag L type lifting blades.
Described little raising evenly is provided with polylith board-type lifting blade in the district.
Be provided with the screw type lifting blade in the described discharge zone, the screw type lifting blade along the drum shaft of discharge zone in spiral distribution.
The beneficial effect that the utility model had is:
1, select direct-type fluorite rotary drying machine for use, fluorite directly contacts with hot blast, and hot blast is taken away wet part of fluorite evaporation, and drop temperature is reduced to 80 ℃ by 120 ℃, and the thermal efficiency is high;
2, the zigzag L type lifting blade of preheating zone has increased the contact area of material and hot blast, has improved drying efficiency;
3, the zigzag L type lifting blade of dry section and board-type lifting blade arranged crosswise have reduced the area of wind-tunnel, have reduced hear rate, and have avoided the damage of high-temperature hot-air to cloth bag;
4, little district of raising increases straight plate lifting blade, has not only reduced airborne dust, and has avoided the material caking;
5, the screw type lifting blade of discharge zone is accomplished spiral discharging, and discharging is more even.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1, spiral feed zone; 2, preheating zone; 3, dry section; 4, little district of raising; 5, guide
The district; 6, discharge zone; 7, zigzag L type lifting blade; 8, board-type lifting blade; 9, screw type lifting blade.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1; Described novel direct-type fluorite rotary drying machine; Comprise direct-type fluorite rotary drying machine; The cylindrical shell of direct-type fluorite rotary drying machine comprises successively the preheating zone 2 that connects, dry section 3, littlely raises district 4, guide district 5 and discharge zone 6, and preheating zone 2, dry section 3, little raising in district 4 and the discharge zone 6 be provided with lifting blade, and preheating zone 2 front ends connect the spiral feed zone 1 of direct-type fluorite rotary drying machine.Evenly be provided with polylith zigzag L type lifting blade 7 on the cylindrical shell circumference of preheating zone 2.Evenly be provided with polylith zigzag L type lifting blade 7 and board-type lifting blade 8 on the cylindrical shell circumference of dry section 3, and board-type lifting blade 8 in interval between per two zigzag L type lifting blades 7.Little raising in the district 4 evenly is provided with polylith board-type lifting blade 8.Be provided with screw type lifting blade 9 in the discharge zone 6, screw type lifting blade 9 along the drum shaft of discharge zone in spiral distribution.
Material carries out preheating through preheating zone 2 successively through spiral feed zone 1 during use, and the zigzag L type lifting blade 7 of preheating zone 2 has increased the contact area of material and hot blast, has improved preheating efficient.Material after the preheating gets into dry section 3 and carries out bake drying, and the zigzag L type lifting blade 7 and board-type lifting blade 8 arranged crosswise of dry section 3 have reduced the area of wind-tunnel, have reduced hear rate, and have avoided the damage of high-temperature hot-air to cloth bag.Dried material is discharged through little district 4, guide district 5 and discharge zone 6 backs of raising.Wherein little district 4 of raising increases straight plate lifting blade 8, has not only reduced airborne dust, and has avoided the material caking, and screw type lifting blade 9 is set in the discharge zone 6, makes discharging after the article screw, and discharging is more even.
