Description
Technical field
The utility model relates to technical field of agricultural product process.
Background technology
Dry object is the needs in order to material uses or processes further.As the drying of timber before making wooden model, woodenware can prevent product deformation, ceramic batch drying before calcination can prevent finished product from chapping.Dried material is also convenient to transport and storage in addition, if the grain drying that will gather in the crops is below certain moisture content, with anti-mildew.
Adopt natural drying in prior art, but this mode far can not meet the needs of production development, production efficiency is low and large to weather dependence more.
Utility model content
The utility model is intended to provide grain dryer, to enhance productivity.
Grain dryer in this programme, comprise upper table, helix tube, lower table, fixed head and dividing plate, helix tube is spatially spiral shape, helix tube connects upper table, lower table, dog-house and blast pipe is provided with in upper table, discharging opening and air inlet pipe is provided with in lower table, fixed head that some cross sections are rectangle is provided with and some cross sections are corrugated dividing plate in helix tube, fixed head is fixed on helix tube inwall, dividing plate is fixed on fixed head, helix tube inner chamber is divided into how emptying by dividing plate and fixed head, often emptying comprises some food passageway spaced apart and hot-air channel, food passageway is communicated with dog-house with hot food passageway upper end, food passageway lower end communicates with discharging opening, hot-air channel upper end is communicated with blast pipe, hot-air channel lower end communicates with air inlet pipe.
Helix tube inner chamber is divided into how emptying by dividing plate and fixed head, and often emptying comprises some food passageway spaced apart and hot-air channel, ensures the utilization ratio of hot-air and the heat exchange area of grain.During work, grain is cast from dog-house, grain can glide by the food passageway in helix tube under gravity, and hot-air can rise and heated barrier along helix tube after entering blast pipe automatically, hot-air and grain form convection effect, sufficient heat exchange, and constantly can contact dividing plate thus fully drying in grain downslide process, finally go out from discharging opening, and hot-air is being discharged from blast pipe, the utility model structure is simple, easy to operate, rapid draing, substantially increases production efficiency.
Further, helix tube is Reducing screw pipe, and helix tube from top to bottom screw diameter increases gradually, increases effective work area of grain and hot-air, and grain and hot-air are fully reacted, and improves drying efficiency.
Further, the pitch of helix tube reduces from top to bottom gradually, has both reduced the acceleration of grain, grain speed is tended towards stability, in turn increase effective work area of grain and hot-air, grain and hot-air are fully reacted, improve drying efficiency.
Further, also comprise air pump, air pump one end is communicated with escape pipe, and the air pump other end is communicated with air inlet pipe, and air inlet pipe place is also provided with heater, hot air circulate can be utilized, and avoids polluting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the front view of the utility model embodiment;
Fig. 3 is that A-A in Fig. 2 is to sectional drawing.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: upper table 1, helix tube 2, lower table 3, fixed head 21, dividing plate 22.
Embodiment is substantially as shown in accompanying drawing 1 to Fig. 3: grain dryer, comprise upper table 1, helix tube 2, lower table 3, fixed head 21 and dividing plate 22, helix tube is spatially spiral shape, helix tube connects upper table, lower table, dog-house and blast pipe is provided with in upper table, discharging opening and air inlet pipe is provided with in lower table, fixed head that some cross sections are rectangle is provided with and some cross sections are corrugated dividing plate in helix tube, fixed head is fixed on helix tube inwall, dividing plate is fixed on fixed head, helix tube inner chamber is divided into how emptying by dividing plate and fixed head, often emptying comprises some food passageway spaced apart and hot-air channel, food passageway is communicated with dog-house with hot food passageway upper end, food passageway lower end communicates with discharging opening, hot-air channel upper end is communicated with blast pipe, hot-air channel lower end communicates with air inlet pipe, helix tube is Reducing screw pipe, helix tube from top to bottom screw diameter increases gradually, increase effective work area of grain and hot-air, grain and hot-air are fully reacted, improve drying efficiency, the pitch of helix tube reduces from top to bottom gradually, both the acceleration of grain had been reduced, grain speed is tended towards stability, in turn increase effective work area of grain and hot-air, grain and hot-air are fully reacted, improve drying efficiency, also comprise air pump, air pump one end is communicated with escape pipe, the air pump other end is communicated with air inlet pipe, air inlet pipe place is also provided with heater, described heater is resistance wire, hot air circulate can be utilized, avoid polluting.
Helix tube inner chamber is divided into how emptying by dividing plate and fixed head, and often emptying comprises some food passageway spaced apart and hot-air channel, ensures the utilization ratio of hot-air and the heat exchange area of grain.During work, grain is cast from dog-house, grain can glide by the food passageway in helix tube under gravity, and hot-air can rise and heated barrier along helix tube after entering blast pipe automatically, hot-air and grain form convection effect, sufficient heat exchange, and constantly can contact dividing plate thus fully drying in grain downslide process, finally go out from discharging opening, and hot-air is being discharged from blast pipe, the utility model structure is simple, easy to operate, rapid draing, substantially increases production efficiency.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect the effect of the utility model enforcement and the practicality of utility model.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
