Abstract
The utility model discloses a kind of dryer heat source temperature control devices, including boiler, the outlet end of the boiler is connected with oil outlet pipe, the outlet end of the oil outlet pipe is connected with cooling fin, the cooling fin carries out radiating treatment to the conduction oil that boiler is spread out of, the cooling fin is connected by oil return line with boiler, and electronic three-way valve component is communicated in the oil outlet pipe, another connecting pin of the electronic three-way valve component is connected with oil return line.The present apparatus sends out command signal when the control terminal of drying machine to boiler, just flowed into electronic three-way valve component from the conduction oil for the high temperature that boiler flows out, make the conduction oil under the condition of high temperature without contacting cereal during the drying process because of being unable to control, ensure cereal during the drying process by suitable temperature, the quality for improving cereal, achieves the purpose of energy saving simultaneously.
Description
Technical field
The utility model is related to grain-drying control field more particularly to a kind of dryer heat source temperature control devices.
Background technology
In drying daily production activity, the heat source fuel that dryer is commonly used has liquid, gas, heat carrier, electricity
The forms such as energy and solid.We summarize dryer heat source, and there are two main classes：Various fuel, as coal, natural gas, liquefied petroleum gas,
Flammable chemical gas；Various origin of heat, such as the combustion product of air, vapor, hot water, electric energy (road oil generation).In reality
Drying and processing is carried out to cereal using heat conducting oil boiler in application process, therefore technical staff needs during to grain-drying
The temperature of conduction oil is monitored in real time, be controlled by the flow direction to recycle oil, it is ensured that the drying temperature of cereal.
It ensure that the quality of cereal, while saving the energy.However it is existing remember in dryer heat source temperature control device use
By the temperature feedback of low temperature grain drying machine to boiler, the drying of cereal is controlled by the burning of boiler and the process that is stopped
Temperature, but there are following defects for which：Since the distance of drying machine and heat source boiler is all far, when in the control of drying machine
The heart issues commands to boiler, and boiler and horse back make the reaction shut down, but even if boiler makes the action shut down, due to heat
The conduction in source needs time and distance, when being reacted to grain-drying temperature surface, serious postposition.In addition boiler temperature is used
Grain temperature is weighed, grain-drying non-uniform temperature can be caused, causes that grain quality reduces or even cereal is discarded, therefore cannot
The phenomenon that being precisely controlled grain temperature, leading to energy waste occurs.
Utility model content
According to problem of the existing technology, the utility model discloses a kind of dryer heat source temperature control device, packets
Boiler is included, the outlet end of the boiler is connected with oil outlet pipe, and the outlet end of the oil outlet pipe is connected with cooling fin, institute
It states cooling fin and radiating treatment is carried out to the conduction oil that boiler is spread out of, the cooling fin is connected by oil return line with boiler, institute
It states and is communicated with electronic three-way valve component in oil outlet pipe, another connecting pin and the oil return line phase of the electronic three-way valve component
Connection.
The thermometer for fluid temperature information in signal piping is provided in the oil outlet pipe and oil return line.
By adopting the above-described technical solution, a kind of dryer heat source temperature control device provided by the utility model, when
The control terminal of drying machine sends out command signal to boiler, and the conduction oil of the high temperature just flowed out from boiler flows into electronic three-way valve group
In part, makes the conduction oil under the condition of high temperature without contacting cereal during the drying process because of being unable to control, ensure that cereal exists
By suitable temperature in drying course, the quality of cereal is improved, is achieved the purpose of energy saving simultaneously.Due to the letter of its structure
It is single, it is not only convenient for producing, and cost is very cheap suitable for being widely popularized.
Description of the drawings
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments described in application, for those of ordinary skill in the art, without creative efforts,
Other drawings may also be obtained based on these drawings.
Fig. 1 is the structural schematic diagram of dryer heat source temperature control device.
Specific implementation mode
To keep the technical solution of the utility model and advantage clearer, with reference to attached in the utility model embodiment
Figure, clearly completely describes the technical scheme in the embodiment of the utility model：
A kind of dryer heat source temperature control device as shown in Figure 1, including boiler 1, the outlet end of boiler 1 and flowline
Road 2 is connected, and the outlet end of the oil outlet pipe 2 is connected with cooling fin 4, the conduction oil that the cooling fin 4 spreads out of boiler 1
Radiating treatment is carried out, cooling fin 4 is connected by oil return line 5 with boiler 1, and electronics threeway is communicated in the oil outlet pipe 2
Another connecting pin of valve module 6, electronic three-way valve component 6 is connected with oil return line 5.
Further, it is provided with for fluid temperature information in signal piping on the oil outlet pipe 2 and oil return line 5
Thermometer 7.The temperature of the liquid in oil outlet pipe 2 is monitored in real time using thermometer 7, ensures that the temperature of conduction oil will not
It is excessively high.
Further, electronic three-way valve component 6 has the function of converting analog signals into digital signal.Wherein dryer
The monitoring client of heat source temperature control device has PLC controller, wherein PLC controller real-time control electronic three-way valve component 6
Work.
A kind of dryer heat source temperature control device disclosed by the utility model, by electronic three-way valve component 6 by high temperature
High temperature oil is diverted from oil outlet pipe 2 under state, by the control of the flow direction to recycling oil temperature, prevents conduction oil due to temperature
Spend high the phenomenon that causing the quality of cereal to reduce, it is ensured that the drying temperature of cereal ensure that the quality of cereal, save simultaneously
The energy.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality
