Cold air, cold air are flowed into tank body after being heated by the hot gas in heating interlayer 11 '；Then straight from wind pipe 14 ' again
Pick out wind；It after cold wind after will drying passes through the Hot-blast Heating of the outer wall of dry tank body, introduces in tank body, but the sludge is dry
Dry tank cannot be recycled waste hot gas, and such significant wastage energy can not reduce enterprise's production cost.
Summary of the invention
In order to overcome the problems referred above, the purpose of the utility model is to provide a kind of hot-gas recoverer, help to solve existing
The waste hot gas of drying sludge tank recycles, and reduces production cost.
The utility model is realized using following scheme: a kind of hot-gas recoverer, and the hot-gas recoverer is applied to dirt
On mud drying chamber, described device includes hot wind buffer tank, Shaftless screw conveyor and exhaust fan, the shaftless screw conveying
Fixed block is fixed on the two sides of machine, spiral is provided with bolt on the fixed block, and one end of the Shaftless screw conveyor is passed through
It wears the outer wall of drying sludge tank and extends in drying sludge tank, and Shaftless screw conveyor is locked together in by the dirt by bolt
On the outer wall of mud drying chamber, the other end of the Shaftless screw conveyor is provided with an outlet, which passes through a first pipe
It is connect with the exhaust fan, the exhaust fan is connect by a second pipe with an air-exhausting duct, and the hot wind buffer tank includes one
Inner wall and an outer wall are a hollow cavity, the hollow cavity of the air-exhausting duct and the hot wind buffer tank between inner and outer wall
Connection, the hot wind buffer tank are provided with a discharge pipe.
Further, the fixed block is square fixed block.
Further, the bolt is wing bolt.
Further, the hot wind buffer tank is set on the drying sludge tank pipeline, and hot wind buffer tank is positioned at dry
Between dry device and drying sludge tank.
The utility model has the beneficial effects that: the utility model passes through exhaust fan for the intracorporal waste hot gas of drying sludge tank
Extraction, i.e. hot gas flow velocity in quickening drying sludge tank body, are transported to hot wind surge tank for waste hot gas further through air-exhausting duct, using useless
Hot gas preheats the cold air in hot wind surge tank, improves hot gas service efficiency, reduces enterprise's production cost；This is practical new
Type is also provided with Shaftless screw conveyor before exhaust fan, prevents sludge tank intracorporal by the way that Shaftless screw conveyor is i.e. effective
Sludge is taken away by exhaust fan, and does not influence waste hot gas and taken away out of tank body by exhaust fan, ensuring equipment reliability of operation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the prior art.
Fig. 2 is the circulating line top view of Fig. 1 prior art.
Fig. 3 is the structural schematic diagram of the utility model.
