The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is done explanation in further detail.
Embodiment
As depicted in figs. 1 and 2, a kind of belt circulation dryer, it comprises feed zone 2, interlude 3, rear 5, discharging section 6, cooling section 7, conveying belt of lower floor 9, upper strata conveyer belt 10, circulating fan 11 and cooling blower 12.Wherein: feed zone 2, interlude 3 and rear 5 are in turn connected into single-piece frame; Upper strata conveyer belt 10 is positioned at single-piece frame with conveying belt of lower floor 9; Circulating fan 11 is positioned on the rear 5, and cooling section 7 one sides connect the exit side of said single-piece frame, and the opposite side of cooling section 7 connects discharging section 6; Conveying belt of lower floor 9 is communicated with discharging section 6 through cooling section 7; Cooling section 7 belows have the gap 13 with atmosphere, and cooling section 7 tops are provided with gas skirt 14, and the outlet of gas skirt 14 connects the air inlet of cooling blower 12.
During operate as normal; Material 4 gets in the single-piece frame that is made up of feed zone 2, interlude 3 and rear 5 through the import of feed zone 2; Material 4 at first drops on the upper strata conveyer belt 10 and motion, upper strata conveyer belt 10 and conveying belt of lower floor 9 operations, and material 4 will progressively drop on conveying belt of lower floor 9 and motion.In this process, high-temperature gas in single-piece frame, do under the drive of circulating fan 11 shuttling movement and repeatedly with upper and lower conveyer belt on material 4 contact, the realization drying materials purpose.The oven dry material 4 of high temperature gets into cooling section 7 through conveying belt of lower floor 9, and the ambient air that cooling blower 12 will be colder this moment contacts with the oven dry material 4 of high temperature, realizes the reduction of temperature of charge.Material 4 after temperature lowers is last through the described belt circulation of discharging section 6 discharge the utility model dryer.
For reducing the hot blast channelling of complete machine and environment, reduce thermal losses, improve drying efficiency.The utility model is preferred: be provided with the curtain plate 8 that keeps out the wind between cooling section 7 and the discharging section 6.
Further, scurry into cooling section for preventing the hot blast in the single-piece frame, the utility model can be preferred: establish the curtain plate 8 that keeps out the wind between cooling section 7 and the single-piece frame exit side.
In fact, the gas environmental gas relatively on every side that cooling blower 12 is discharged still has higher thermal resource, and for utilizing above-mentioned thermal resource, it is inner that the air outlet of cooling blower 12 is communicated with single-piece frame.After further preferred this technical scheme, the relatively-high temperature gas that cooling section produces just can get into single-piece frame inside, and the material in the single-piece frame is carried out the circulation oven dry, improves utilization efficiency of energy, has reduced the energy consumption of dryer.
For material can be evenly distributed on the conveyer belt of upper strata, also can establish feeder 1, feeder 1 is connected with the charging aperture of feed zone 2.Like this, material just can be evenly distributed on the conveyer belt of upper strata, prevents solid accumulation, improves drying effect.
The utility model is not limited to the foregoing description, and the technical scheme that all employings are equal to or the equivalence replacement forms all falls into the protection domain that the utility model requires.
