To sum up, the beneficial effects of the utility model are that, compared with the prior art, dry conveyor adopts the mode of carrying while dry, has improved work efficiency, and the mode of the double-deck heat conduction of rethread has guaranteed dry effect, and the while sealed material is said and has been inhibited the smell and has been gived off at will, and heat-conducting medium also can cyclic utilization, and each is carried the section and is connected unblocked, stops the jam condition and takes place, is convenient for maintain, is applicable to in the automated processing production line.

Drawings

Fig. 1 is a schematic structural diagram of a drying and conveying device provided by an embodiment of the present invention;

fig. 2 is a cross-sectional view of a drying and conveying device provided by an embodiment of the present invention.

Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Referring to fig. 1 and 2, the present embodiment provides a drying and conveying device, which can be used for conveying and drying sludge, domestic garbage and industrial waste for subsequent processing, and includes a plurality of conveying sections connected end to end, so that the problem of difficult treatment under the condition of blockage can be avoided in a multi-section conveying manner, and the device is convenient to maintain. Each conveying section is arranged obliquely upwards, the preferred inclined angle is 15-20 degrees, and each conveying section comprises a trough 1, a bottom shell 2 and a housing 3.

The material trough 1 is internally provided with a rotating shaft with a helical blade 4, the head end of the conveying section is provided with a motor 5 for driving the rotating shaft, and the material is conveyed from low potential to high potential according to the Archimedes spiral principle.

The housing 3 is fixedly connected with the trough 1 to form a sealing material channel 6, and high-temperature gas is introduced into the sealing material channel 6, wherein the high-temperature gas is preferably steam or hot air.

The head end of carrying the section is provided with pan feeding mouth 7, and the tail end is provided with down the cover 8, and pan feeding mouth 7, down the cover 8 all say 6 intercommunications with sealed material, and the lower cover 8 of preceding transport section and the last material mouth sealing connection of back transport section link up the pan feeding mouth 7 department of lower cover 8 and be provided with the air inlet 9 that blows high-temperature gas, are provided with gas outlet 10 on the housing 3 of head and the tail transport section.

It should be noted that the material falls freely from the blanking cover 8 and is blown by the steam of the air inlet 9 to form a parabolic fall, so that the drying effect is improved, the problem that the mouthpiece is easy to block is solved, and the blanking cover 8 is provided with the observation port 11.
