Description
Technical field
The utility model relates to a kind of drying machine, specifically a kind of drying machine preheating device.
Background technology
At present, drying machine is widely used in the drying to dry powder shape and fine particulate material.In the existing drying equipment, it is dry generally to adopt convection type to conduct heat.As utilize hot-air drying, hot-air to contact with the material that is dried and carry out heat exchange with transpiring moisture, but usually can form flame material is burnt because of hot air temperature is too high, cause unnecessary waste.Simultaneously, when humidity of materials (about water content 45%) was big, owing to there is not preheating device, material also remained about 30% water content after drying, need repeat repeatedly drying, just can meet the demands, and the thermal efficiency is low, and energy resource consumption is big.
Summary of the invention
The purpose of this utility model provides the preceding drying machine preheating device that material is carried out preheating of a kind of dry materials.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of drying machine preheating device, it comprises frame, frame is provided with the casing of sealing, be provided with the barrel that is used for material channel in the casing, form the air channel that isolates with material channel between casing and the barrel, air channel one end is communicated with the air inlet pipe that thermal source is provided, the other end is communicated with hopper on being installed in casing, the feed end of barrel is connected with feed hopper, discharge end is communicated with hopper, is provided with in the barrel to make material by the conveying mechanism of feed end to the discharge end motion.
Conveying mechanism of the present utility model comprises the power that is installed in frame, and by the helical axis that power drives, helical axis is installed in the barrel, and helical axis is provided with the screw propulsion blade.
The utility model stops up for preventing material, and described helical axis is provided with scraper plate at the discharge end of barrel.
The utility model is heated evenly for making material, is provided with the wind deflector that makes hot blast be the motion of " ∽ " shape in the described air channel.
The utility model enters in the barrel for preventing cold air, and described feed hopper is provided with Blowing stopper.
The utility model is the convenient fault of checking, described hopper is provided with observes door.
The utility model is the temperature in the control casing, and described air inlet pipe is provided with deep bead with the place of connection in air channel.
Because adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, adopt conduction-type that material is carried out preheating and drying, thermal efficiency height, material is behind preheating and drying, its moisture content reduces greatly, is beneficial to down to go on foot with countercurrent drier material to be carried out drying.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As seen from Figure 1, Figure 2, a kind of drying machine preheating device, it comprises frame 7, frame 7 is provided with the casing 9 of sealing, be provided with the barrel 10 that is used for material channel 20 in the casing 9, form the air channel 19 that isolates with material channel 20 between casing 9 and the barrel 10, air channel 19 1 ends are communicated with the air inlet pipe 2 that thermal source is provided, the other end is communicated with hopper 11 on being installed in casing 9, the feed end of barrel 10 is connected with feed hopper 4, discharge end is communicated with hopper 11, is provided with in the barrel 10 to make material by the conveying mechanism of feed end to the discharge end motion.
Conveying mechanism of the present utility model comprises the power 14 that is installed in frame 7, and by the helical axis 5 that power 14 drives, helical axis 5 is installed in the barrel 10, and helical axis 5 is provided with screw propulsion blade 6.
The utility model stops up for preventing material, and described helical axis 5 is provided with scraper plate 12 at the discharge end of barrel 10.
The utility model is heated evenly for making material, is provided with the wind deflector 8 that makes hot blast be the motion of " ∽ " shape in the described air channel 19.
The utility model enters in the barrel 10 for preventing cold air, and described feed hopper 4 is provided with Blowing stopper 3.
The utility model is the convenient fault of checking, described hopper 11 is provided with observes door 15.
The utility model is the temperature in the control casing 9, and described air inlet pipe 2 is provided with deep bead 17 with the place of connection in air channel 19.
During the utility model work, by the wet stock (moisture content is about 45%) after the pulverizer pulverizing, as the bamboo powder, wood powder etc., present embodiment is the bamboo powder, the bamboo powder is by Blowing stopper 3, feed hopper 4 enters barrel 10, when bamboo pruinescence screw propulsion blade 6 advances, hot-air in the drying room 1 enters air channel 19 by air inlet pipe 2 under the effect of air blast 16, because bamboo powder and Hot air quilt barrel 10 are isolated, therefore, the bamboo powder can not burn because hot air temperature is too high, the bamboo powder evaporates part moisture in the process of carrying, bamboo pruinescence screw propulsion blade 6 behind preheating and drying (at this moment moisture content is about 20%) pushes in the hopper 11, and by air blast 16, carrier pipe 13 is pumped to drying room 1 further dry, and dried bamboo powder (at this moment moisture content is about 8%) is sent through drawing mechanism 18.
