Abstract
The utility model is related to the drying machines that the technical field of drying machine more particularly to a kind of two overheat are protected.If the temperature that Omron temperature controller measures heat-generating pipe is higher than the first preset temperature, trigger relay disconnects the power supply of heat-generating pipe；If Omron temperature controller fails, and the constant temperature of heat-generating pipe is increased to the second preset temperature, then change the power supply that heat-generating pipe is disconnected by EGO temperature controller trigger relays, accordingly even when Omron temperature controller fails, also EGO temperature controllers replace the function of Omron temperature controller, the temperature of dual monitoring heat-generating pipe, to make heat-generating pipe be not easy to be burned because temperature is excessively high.
Description
Technical field
The utility model is related to the drying machines that the technical field of drying machine more particularly to a kind of two overheat are protected.
Background technology
Drying machine is widely used in plastic cement drying processing technique field and the dry field of some other high-temperature heating.It is dry at present
Dry machine generally all has overtemperature protection system, i.e., when the heat-generating pipe of drying machine is higher than a certain preset temperature, overtemperature protection system
The power supply that just will disconnect heat-generating pipe, it is excessively high to be burned to avoid the temperature of heat-generating pipe.But current drying machine generally only has
One overtemperature protection system, if the overtemperature protection system fails, then heat-generating pipe is just easy to be burned because temperature is excessively high
.
Invention content
The purpose of this utility model is to provide a kind of hardware configuration of the drying machine of two overheat protection, for soft project
Heat-generating pipe that can be in duplicate protection drying machine after teacher's programming is not burned because temperature is excessively high.
The utility model provides a kind of drying machine of two overheat protection, including described in heat-generating pipe for heating, control
Relay, Omron temperature controller and the EGO temperature controllers of heat-generating pipe on/off, the Omron temperature controller and the EGO temperature controls
Device connects the heat-generating pipe by the relay and controls the start and stop of the heat-generating pipe, and the Omron temperature controller measures institute
The temperature for stating heat-generating pipe is higher than the first preset temperature, then triggers the power supply that the relay disconnects the heat-generating pipe；If the Europe
Nurse dragon temperature controller fails, and the constant temperature of the heat-generating pipe is increased to the second preset temperature, then changes and touched by the EGO temperature controllers
Sending out relay described disconnects the power supply of the heat-generating pipe.
Wherein, including drying box, wind turbine and control cabinet, the wind turbine connect the drying machine and the control cabinet.
Wherein, it is connected with device for drying and filtering between the wind turbine and the drying machine.
Wherein, the top of the drying box is equipped with dismountable head cover.
Wherein, the Omron temperature controller and the EGO temperature controllers are located on the control cabinet.
Wherein, further include chassis, the drying box, the wind turbine and the control cabinet are each provided on the chassis.
Wherein, the first preset temperature is 120 degree, and the second preset temperature is 130 degree.
The beneficial effects of the utility model are：If Omron temperature controller measures the temperature of heat-generating pipe higher than the first default temperature
It spends, then trigger relay disconnects the power supply of heat-generating pipe；If Omron temperature controller fails, and the constant temperature of heat-generating pipe is increased to the
Two preset temperatures then change the power supply that heat-generating pipe is disconnected by EGO temperature controller trigger relays, accordingly even when Omron temperature controller loses
Effect also has EGO temperature controllers to replace the function of Omron temperature controller, the temperature of dual monitoring heat-generating pipe, to make heat-generating pipe not allow
Easily it is burned because temperature is excessively high.
Description of the drawings
Using attached drawing, the utility model is described in further detail, but the embodiment in attached drawing is not constituted to the utility model
Any restrictions for those of ordinary skill in the art without creative efforts, can also be according to following attached
Figure obtains other attached drawings.
Fig. 1 is a kind of schematic block circuit diagram of the drying machine of two overheat protection of the utility model.
Fig. 2 is a kind of structural schematic diagram of the drying machine of two overheat protection of the utility model.
Include in Fig. 1 to Fig. 2：1 --- drying box, 2 --- wind turbine, 3 --- control cabinet, 4 --- device for drying and filtering,
5 --- chassis, 6 --- head cover, 7 --- Omron temperature controller, 8 --- EGO temperature controllers, 9 --- relay, 10 --- fever
Pipe.
Specific implementation mode
The utility model is further described with the following Examples.
The utility model provides a kind of drying machine of two overheat protection, as depicted in figs. 1 and 2, including it is for heating
Heat-generating pipe 10, relay 9, Omron temperature controller 7 and the EGO temperature controllers 8 for controlling 10 on/off of heat-generating pipe, Omron temperature controller
7 and EGO temperature controllers 8 connect heat-generating pipe 10 by relay 9 and control the start and stop of heat-generating pipe 10, if Omron temperature controller 7 is surveyed
The temperature for obtaining heat-generating pipe 10 is higher than the first preset temperature, then trigger relay 9 disconnects the power supply of heat-generating pipe 10；If Omron temperature control
Device 7 fails, and the constant temperature of heat-generating pipe 10 is increased to the second preset temperature, then change by 8 trigger relay 9 of EGO temperature controllers
Disconnect the power supply of heat-generating pipe 10.Accordingly even when Omron temperature controller 7 fails, also there are EGO temperature controllers 8 to replace Omron temperature controller 7
Function, the temperature of dual monitoring heat-generating pipe 10, to make heat-generating pipe 10 be not easy to be burned because temperature is excessively high.Using price
Cheap and technology maturation Omron temperature controller 7 and EGO temperature controllers 8 are used as temperature controller, can simplify circuit design.
In the present embodiment, this drying machine includes chassis 5, drying box 1, wind turbine 2 and control cabinet 3, wherein drying box 1, wind turbine
2 and control cabinet 3 be each provided on chassis 5, wind turbine 2 connects drying machine and control cabinet 3.It is connected between wind turbine 2 and the drying machine
Device for drying and filtering 4.Control cabinet 3 controls wind turbine 2 and works, and the air of drying box 1 is arranged after the filtering of device for drying and filtering 4 and arrives air
