Abstract
The utility model discloses a kind of rotary-drum drier, including holder, there are two roller heaters for setting on holder, two spaces formed between roller heater and holder are wet feed device, roller heater can be contacted with wet feed, be additionally provided with pocket knife in the upper outer of roller heater, pocket knife is contacted with the outer surface of roller heater, it is additionally provided with vapour hood above roller heater, reheating conveyer is equipped in the lower section of the outside pocket knife of roller heater.Rotary-drum drier provided by the utility model, dried material collecting device are changed to reheating conveying equipment, can be further dried to the material after drying, reduce its water content.
Description
Technical field
The utility model belongs to drier technical field, and in particular to a kind of rotary-drum drier.
Background technology
Drum dryer is the continuous dryer heated with heat-conducting mode, it is suitable for solution, suspension, colloidal solution etc.
The drying of flowable materials has been widely used in fields such as food, drug, biological products, dyestuff, plastics.The diameter of roller
Generally 0.5~1.0m, length are 1~3m, rotating speed is 1~3r/min.The water content for handling material can be 10~80%.Roller
Drying thermal efficiency is high (thermal efficiency is 70~80%), and power consumption is small (being about 0.02~0.05kW/kg water), dry tenacity
(30~70kg water/(hm2)) greatly, residence time of material is short (5~30s), easy to operate.But drum dryer is complicated,
Heat transfer area is small, and dry products water content is higher (generally 3~10%), and traditional method is to reduce the rotating speed of roller to lengthen
The time of dry materials reduces water content, but this method increases process time, reduces efficiency.
Utility model content
Purpose of utility model：In view of the deficienciess of the prior art, the purpose of the utility model is to provide a kind of rollers
Formula drier, dried material collecting device are changed to reheating conveying equipment, can be carried out to the material after drying further
It is dry, reduce its water content.
Technical solution：In order to realize that above-mentioned purpose of utility model, the technical solution adopted in the utility model are as follows：
A kind of rotary-drum drier, including holder, on holder setting there are two roller heater, two roller heaters and
The space formed between holder is wet feed device, and roller heater can be contacted with wet feed, also be set in the upper outer of roller heater
It is equipped with pocket knife, pocket knife is contacted with the outer surface of roller heater, vapour hood is additionally provided with above roller heater, in roller heater
Outside pocket knife lower section be equipped with reheating conveyer.
Preferably, reheating conveyer includes screw conveyor, the feed inlet of screw conveyor is located under pocket knife
Orientation is set, and the material wiped off of pocket knife is collected, and a hot-air input port is arranged close to the lower part of discharge end in screw conveyor, close into
An air outlet slit is arranged in one end top of material mouth, is additionally provided with air-heater below hot-air input port, air-heater is defeated with hot-air
Entrance connects.
Preferably, reheating conveyer is belt dryer, the wet feed device entrance of belt dryer is located at pocket knife
Lower position.
Advantageous effect：Compared with prior art, the utility model has the following advantages：
Dried material collector in the prior art is revised as reheating conveyer, not only may be implemented to material again
Secondary heating reduces its water content；And the after-heater with transportation function can be directly by material transportation to follow-up equipment
In, complete the collection transport of material.
Description of the drawings
Fig. 1 is the structural schematic diagram of rotary-drum drier；
Fig. 2 is the structural schematic diagram of reheating conveyer.
Specific implementation mode
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, embodiment is with the utility model skill
Implemented under premised on art scheme, it should be understood that these embodiments are merely to illustrate the utility model rather than limit this practicality
Novel range.
As depicted in figs. 1 and 2, a kind of rotary-drum drier, including holder 1, there are two roller heaters for setting on holder 1
2, the space formed between two roller heaters 2 and holder is wet feed device 3, and roller heater 2 can be contacted with wet feed, hot rolling
Cylinder heater 2 touches wet stock and takes wet stock bonding out of, and pocket knife 4 is additionally provided in the upper outer of roller heater 2, small
Knife 4 is contacted with the outer surface of roller heater 2, and for wiping the material on roller after drying off, 2 top of roller heater is additionally provided with
Vapour hood 5 is equipped with dried material collector 6, unlike the prior art in the lower section of the outside pocket knife 4 of roller heater 2
Dried material collector 6 is replaced by reheating conveyer.
Reheating conveyer includes screw conveyor 7, and 7 top of screw conveyor is provided with feed inlet 8, feed inlet 8
In the lower position of pocket knife 4, the material that pocket knife 4 is wiped off is collected, a hot-air is arranged close to the lower part of discharge end in screw conveyor 7
An air outlet slit 10 is arranged close to one end top of feed inlet 8 in input port 9, and the lower section of hot-air input port 9 is additionally provided with air-heater
11, air-heater 11 is connect with hot-air input port 9.It is dropped into screw conveyor 7 from feed inlet 8 by the material that pocket knife 4 is wiped off,
Rotary shaft in screw conveyor 7, the helical blade also welded on the rotary shaft drive material movement, another aspect thermal current
It is flowed from the discharge end of screw conveyor 7 to feeding side, the material of screw conveyor 7 is further dried, reduce material
Water content, furthermore the advantages of spiral conveyor 7, can be stirred to material while transported material so that material quilt
Dry is more abundant.
Reheating conveyer can also be belt dryer in the prior art, and belt dryer can carry out material
It is further dry, moreover it is possible to material be transported, realize the function of redrying and transport.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
