Sludge dryer is a link of sludge treatment device, and sludge dryer carries out drying and other treatment to sludge, that is, goes
Except overwhelming majority moisture contained in sludge, and then sludge slag charge is enable to carry out harmless treatment by other equipment or switch to him
With.Such as a kind of sludge drying automatic production line that China Patent Publication No. is 105948431, it includes roasting for stating drying dehumidification machine
Room, heat exchange equipment and conveying equipment, the barn is interior to be equipped with first chamber, second chamber, third chamber, the 4th chamber, the 5th
Chamber and the 6th chamber, the heat exchange equipment include the first blower being arranged in first chamber, are arranged in second chamber
Second blower, setting in the indoor evaporator of the 5th chamber and are arranged in the 6th chamber in the indoor water cooling heat exchanger of third chamber, setting
Indoor condenser；First chamber and the 6th chamber, first motor are located at the bottom of first chamber, and the first blower is by the 6th
In the indoor air sucking first chamber of chamber；First chamber is connected to by the air outlet that side is arranged with second chamber, the second wind
Machine is by the air sucking second chamber in first chamber, and second chamber is by the portion of air of sucking from the top of first chamber
It returns in first chamber, another part air of sucking is sent into third chamber by second chamber；The indoor air of third chamber is logical
Enter the 4th chamber after crossing water cooling heat exchanger and brethaid；The 4th indoor air of chamber enters the 5th chamber after passing through evaporator
Room；The 5th indoor air of chamber is by entering the 6th chamber after brethaid and condenser.The temperature control of this kind of drying dehumidification machine
System is by condenser to heating in oven, when the temperature is excessively high, reducing temperature by water cooling heat exchanger in oven；
This kind of temperature control system is provided with water cooling heat exchanger in circulation, wind path, and the high temperature air looped back is cooled down by water cooling.It should
The temperature fluctuation of kind temperature control system is big, and energy consumption is high.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of sludge dehumidifying desiccation machines, can be realized accurate control
Temperature.
In order to solve the above technical problems, the technical solution of the utility model is: a kind of sludge dehumidifying desiccation machine, including heat pump
System, the heat pump system include that compressor, the inner condenser in barn, the external condenser outside barn, electronics are swollen
Swollen valve, capillary, liquid storage device, evaporator and gas-liquid separator, the output end of the compressor and the input terminal of inner condenser connect
It connects, the output end of inner condenser and the input terminal of electric expansion valve connect, the input of the output end and liquid storage device of electric expansion valve
End connection, the output end of liquid storage device and the input terminal of evaporator connect, the output end of evaporator and the input terminal of gas-liquid separator
Connection, the output end of gas-liquid separator and the input terminal of compressor connect；The output end of the compressor is by solenoid valve and outside
The output end of condenser connects, and the output end of external condenser is connected to by capillary with the output end of electric expansion valve.This is practical
New principle: when the normal drying dehumidification of barn, solenoid valve is closed, and compressor, inner condenser and evaporator form heat pump system,
Heat temperature raising is carried out to the air in barn by inner condenser；When barn temperature is excessively high to be needed to cool down, solenoid valve is opened, this
The refrigerant of Shi Shaoliang is by inner condenser, and most refrigerant is by external condenser, since external condenser is in outside barn,
The refrigerant of the part is externally radiated by external condenser, to reduce the heat of refrigerant, reaching reduces heat pump system heating
The purpose of efficiency.
Brought beneficial effect is the utility model compared with prior art:
When barn temperature is excessively high to be needed to cool down, solenoid valve is opened, refrigerant a small amount of at this time passes through inner condenser, big portion
The refrigerant divided is by external condenser, and since external condenser is in outside barn, the refrigerant of the part is external by external condenser
Heat dissipation achievees the purpose that reduce heat pump system heat efficiency to reduce the heat of refrigerant；The temperature control of this kind of temperature control mode
System is accurate, and temperature fluctuation amplitude is small.
Detailed description of the invention
Fig. 1 is the block diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings of the specification.
The desiccation machine as shown in Figure 1, a kind of sludge dehumidifies, including heat pump system, the heat pump system include compressor, are set to
Inner condenser in barn, the external condenser outside barn, electric expansion valve, capillary, liquid storage device, evaporator and gas-liquid point
From device.The input terminal of the output end of the compressor and inner condenser connects, the output end of inner condenser and electric expansion valve
The input terminal of input terminal connection, the output end of electric expansion valve and liquid storage device connects, the output end of liquid storage device and evaporator it is defeated
Enter end connection, the input terminal of the output end of evaporator and gas-liquid separator connects, the output end of gas-liquid separator and compressor
Input terminal connection.The output end of the compressor is connected by the output end of solenoid valve and external condenser, the output of external condenser
End is connected to by capillary with the output end of electric expansion valve.
The utility model principle: when the normal drying dehumidification of barn, solenoid valve is closed, compressor, inner condenser and evaporation
Device forms heat pump system, carries out heat temperature raising to the air in barn by inner condenser；It needs to cool down when barn temperature is excessively high
When, solenoid valve is opened, electric expansion valve is adjusted, makes refrigerant a small amount of in heat pump system by inner condenser, maintains in barn
Temperature；Most refrigerant passes through external condenser and capillary, since external condenser is in outside barn, the refrigerant of the part
It is externally radiated by external condenser, to reduce the heat of refrigerant, achievees the purpose that reduce heat pump system heat efficiency；This kind
The temperature control of temperature control mode is accurate, and temperature fluctuation amplitude is small.
