B and then the left end installation motor in rotating shaft, while supporting leg is installed at body two ends, it is true when installing supporting leg
The spacing protected between discharging opening and ground is more than 0.8~1.2m, and body is fixed on bottom surface；
C, then four supports of right angle setting on the top surface of body, make the rectangular shape distribution of four supports, then in four branch
Bottom plate is horizontally mounted between frame, spacing between bottom plate and body top surface is more than 0.4~0.6m, and in adjacent two in left and right
Locating rack is installed between support；
Air source heat pump is hoisted to the top of body by d, mechanism to be supported by hoisting machine after installing, make air source heat pump
Transfer to bottom plate, then be fixedly connected locating rack with air source heat pump along vertical direction with lock, then in body
Top surface right-hand member install air intake duct, the right flank of air intake duct and air source heat pump is fixedly connected, at the same air-source heat
Blast pipe with blower fan is installed on the left surface of pump, and the left side lower end of another port of blast pipe and body is consolidated
Fixed connection, finally carries out encapsulation process by the junction of air intake duct and blast pipe；
2) sewage sludge feed is dried
A, after sludge dryer install terminate after, start motor first, make rotating shaft drive helical blade and material stirring-up mechanism it is even
Speed rotation, controls the rotating speed of rotating shaft in 25~30r/min, then by the temperature adjustment of heater to 90~180 DEG C；
After b, standby internal temperature are constant, sludge is loaded into feed hopper, makes sludge in helical blade and the work of material stirring-up mechanism
With lower drying of being heated while at the uniform velocity pushing ahead, the translational speed of sludge matches in the packing speed and body of sludge,
After sludge is pushed to right-hand member from the left end of body, dropped from discharging opening, it is unified to reclaim；
C, when sludge is during drying, the wind guiding mechanism of internal body is adjusted one-way guide flow plate to setting by servomotor
Fixed angle, scattering and disappearing for internal body temperature is slowed down by one-way guide flow plate；
3) waste gas circulation is handled
A, reclaim from discharging opening after sludge heated drying, and damp and hot waste gas then passes through air intake duct air inlet source heat pump
In, dry and cold air is formed after evaporator, then form through the first condenser dry air, and in the presence of blower fan from
Blast pipe is re-entered in body, realizes the circular treatment of waste gas；
After b, Treatment of Sludge terminate, waste gas is discharged after being filtered through air source heat pump；
4) sludge dryer is cleaned
Air source heat pump is removed first, and then each lead into water from exhaust port and air inlet port rushes to the inside of body
Wash, make sewage directly from discharging opening discharge.
