When the sludge is heated and dried, the sludge is recovered from a discharge hole, and the damp and hot waste gas enters an air source heat pump through an air suction pipe, forms dry and cold air after passing through an evaporator, forms dry air through a first condenser, and is re-input into a machine body from an exhaust pipe under the action of a fan, so that the circulation treatment of the waste gas is realized;
b. after the sludge treatment is finished, the waste gas is filtered by an air source heat pump and then is discharged;
4) sludge dryer cleaning
Firstly, the air source heat pump is dismantled, then water is respectively introduced from the exhaust port and the air inlet port to flush the interior of the machine body, so that sewage is directly discharged from the discharge port.
2. The drying method of the air source heat pump low-temperature sludge dryer as claimed in claim 1, characterized in that: the side of the one-way guide plate is provided with a sliding groove, and the push-aid rod is movably connected to the one-way guide plate through a sliding block.
3. The drying method of the air source heat pump low-temperature sludge dryer as claimed in claim 1, characterized in that: the supporting mechanism comprises a support, a bottom plate and a positioning frame, the support is vertically and fixedly connected to the top surface of the machine body, the left support and the right support are fixedly connected through the positioning frame, the front support and the rear support are fixedly connected through the bottom plate, and the bottom plate supports the bottom surface of the air source heat pump.
4. The drying method of the air source heat pump low-temperature sludge dryer as claimed in claim 1, characterized in that: the air source heat pump is characterized in that a partition plate is arranged in the air source heat pump, an air guide channel is arranged below the partition plate, a first condenser, an evaporator and an expansion valve are arranged in the air guide channel, the expansion valve is located between the first condenser and the evaporator, a second condenser and a compressor are arranged above the partition plate, the first condenser is connected with the evaporator through the expansion valve, the evaporator is connected with the compressor, the compressor is connected with the second condenser, and the second condenser is connected with the first condenser.
5. The drying method of the air source heat pump low-temperature sludge dryer as claimed in claim 4, characterized in that: the top surface of the air source heat pump is provided with a ventilation pipe, and a heat exchange fan is arranged in the ventilation pipe.
