Abstract
The utility model discloses a counter-flow-type roller drying machine, which comprises a drying roller and a roller driving device, wherein two ends of the drying roller are respectively provided with an air inlet pipe and an air outlet pipe, the air inlet pipe is provided with a feeding device, and the air outlet pipe is provided with a discharging device. In the utility model, the temperature of materials in the drying machine is lowest when the moisture content of the materials is highest, and is highest when the moisture content of the materials is lowest, that is to say, when in a high-temperature section, the materials have less internal moisture and low evaporation intensity, and when in a low-temperature section, the materials have more internal moisture and high evaporation intensity, and thus, the phenomenon of moisture regain of finished products is avoided; and the heat utilization rate is high and the exhaust emission temperature is low.
Description
Technical field
The utility model relates to the technical field of drying equipment, particularly relates to a kind of reverse-flow cylinder dryer.
Background technology
Existing common cylinder dryer, material and hot blast move towards identical, temperature is the highest when material water ratio is the highest, temperature is minimum when moisture content is minimum, be material when being in high temperature section, the internal moisture height, evaporation intensity is big, when material is in high temperature section, internal moisture is low, and evaporation intensity is little, and material or the heat supply temperature very low for the finished product water content requirement are very low, " moisture regain ", " anti-wet " phenomenon very easily occur, can not obtain drying requirement.
The utility model content
The purpose of this utility model is in order to address the above problem, a kind of reverse-flow cylinder dryer to be provided.
The technical solution of the utility model is: a kind of reverse-flow cylinder dryer, contain drying roller, drum drive, two ends are respectively equipped with blast pipe and discharge pipe on this drying roller, and described air inlet pipe place is provided with feeding device, and described discharge pipe place is provided with drawing mechanism.
Described drum drive contains motor, reductor, comes head roll at the output of reductor by chain transmission or gear drive.
The inwall of described drying roller is provided with the novel combination type raising material unit of intensive intersection and proper angle layout.
The beneficial effects of the utility model
Temperature was minimum when the material water ratio in the dryer of the present utility model was the highest, temperature is the highest when moisture content is minimum, be that material is when being in high temperature section, internal moisture is low, evaporation intensity is little, and when material was in low-temperature zone, internal moisture was big, evaporation intensity is big, has avoided finished product appearance " moisture regain ", " anti-wet " phenomenon; The heat utilization efficiency height, the toxic emission temperature is low.
The novel combination type raising material unit that adopts intensive intersection and proper angle to arrange in the cylinder of this dryer, help improving the number of times of shedding of material, disperse more abundant, be deposited in material on each raising material unit few, pile up shallow, more material is formed a lot of " material curtain " aloft by continuous must shedding, farthest increased skyborne distribution area of material and hang time, enlarged contact area as far as possible and extend contact time the penetrance of raising thermal medium.
Description of drawings
Fig. 1 is one of the hot cylindrical drier axial section of this oil structural representation.
The specific embodiment
Referring to Fig. 1,1. cylinders among the figure, 2. drive unit, 3. discharge pipe, 4. blast pipe, 5. drawing mechanism, 6. feeding device.
Embodiment: a kind of reverse-flow cylinder dryer, contain drying roller, drum drive, two ends are respectively equipped with blast pipe and discharge pipe on this drying roller, and described air inlet pipe place is provided with feeding device, and described discharge pipe place is provided with drawing mechanism.Described drum drive contains motor, reductor, comes head roll at the output of reductor by chain transmission or gear drive.The inwall of described drying roller is provided with the novel combination type raising material unit of intensive intersection and proper angle layout.
The course of work:
This machine in the course of the work, feeding device is made a gift to someone material in the cylinder, drive unit drives the cylinder rotation, cylinder is constantly shed out material in the process of rotation, after the hot-air of process fully contacts with material in the cylinder, moisture in the material is taken away, sent by drawing mechanism at last by the material after drying; The blast pipe of this machine and drawing mechanism are positioned at same end, and discharge pipe and feeding device are positioned at same end, and the trend of material is just opposite with the trend of hot blast, can utilize the heat energy in the hot blast fully.
The novel combination type raising material unit that intensive intersection of inner wall of rotary drum and proper angle are arranged can repeatedly be shed material evenly, farthest increases the time of contact and the contact area of material and hot-air, thereby improves dry speed and efficient.
Claims (3)
1. a reverse-flow cylinder dryer contains drying roller, drum drive, and two ends are respectively equipped with blast pipe and discharge pipe on this drying roller, it is characterized in that: described air inlet pipe place is provided with feeding device, and described discharge pipe place is provided with drawing mechanism.
