Wind pressure micro -gap switch monitoring axial fan's wind pressure is passed through to this embodiment to through near the temperature in temperature controller monitoring heat exchange tube, combustion system monitors simultaneously, and with the linkage of ignition control system, protect combustion system, the life -span and the security of combustor has improved greatly.
Description
Technical field
The utility model relates to a kind of heating equipment, particularly relates to a kind of protection system of gas warm-air machine.
Background technology
Existing larger gas warm-air drier or electric warm-air machine only have employed single protected mode, usually only use temperature controller, and when axial flow blower fault, need after a while, when temperature increases, temperature controller just plays action, and arrestment operates.Can be there are two kinds of defects in this situation: 1, equipment needs dry combustion method a period of time, and temperature can be too high, affects the life-span of equipment; If 2 temperature controllers have been broken, the effect of proterctive equipment just cannot be played, will be abnormally dangerous, even may cause potential safety hazard.
Utility model content
The purpose of this utility model be to provide a kind of can the protection system of duplicate protection gas warm-air machine.
The protection system of a kind of gas warm-air machine that the utility model provides, comprise heat exchanger tube, axial flow blower and Iganition control system, blast microswitch is provided with between described heat exchanger tube and axial flow blower, described blast microswitch comprises the wind pressure monitoring device that monitoring axial flow blower runs, and described blast microswitch also comprises microswitch; After wind pressure monitoring device starts, microswitch is connected, and signal is passed to Iganition control system, described wind pressure monitoring device and the interlock of described microswitch.
Further, described protection system also comprises temperature controller, and described temperature controller is for monitoring the temperature of heat exchanger tube.
Further, described wind pressure monitoring device is for monitoring the duty of axial flow blower.
In the utility model, between heat exchanger tube and axial flow blower, be provided with blast microswitch, and be provided with temperature controller near heat exchanger tube, by the duty of blast microswitch monitoring axial flow blower, simultaneously by the temperature near temperature controller monitoring heat exchanger tube.The present embodiment monitors combustion system by above-mentioned two kinds of modes simultaneously, and links with Iganition control system, protects combustion system, substantially increases life-span and the security of burner.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some accompanying drawings of the utility model embodiment, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the protection system of a kind of gas warm-air machine of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, be the structural representation of the protection system of a kind of gas warm-air machine of the present utility model.
In the present embodiment, comprise heat exchanger tube 1, axial flow blower 2 and Iganition control system 3, blast microswitch 4 is provided with between described heat exchanger tube 1 and axial flow blower 2, described blast microswitch 4 comprises the wind pressure monitoring device 41 that monitoring axial flow blower runs, and described blast microswitch 4 also comprises microswitch 42; After wind pressure monitoring device 41 starts, microswitch 42 is connected, and signal is passed to Iganition control system 3, and described wind pressure monitoring device 41 and described microswitch 42 link.
When fuel gas buring, heat exchanger tube 1, by heat exchanger tube 1, heats by the flue gas of high temperature, and after axial flow blower starts, cold wind blows over heat exchanger tube 1 surface of high temperature, from heat exchanger tube 1 other end out be exactly hot blast.
In the present embodiment, wind pressure monitoring device 41 is for monitoring the duty of axial flow blower 2.When axial flow blower 2 rotates, wind is on blast microswitch 4, and wind pressure monitoring device 41 monitors axial flow blower startup and after having air quantity, the power supply on Iganition control system 3 is connected by microswitch 42, and Iganition control system 3 is lighted a fire, and normally works.When axial flow blower breaks down, wind pressure monitoring device 41 is monitored less than there being air quantity process, and microswitch 42 will control point ignition control system 3 power-off, makes equipment out of service, protection warm-air drier.
In the present embodiment, protection system also comprises temperature controller 5, and described temperature controller 5 is for monitoring the temperature of heat exchanger tube.Described temperature controller 5 is positioned at the other end relative to blast microswitch 4 of heat exchanger tube, and is placed in the inner side of the middle bent tube section of S type heat exchanger tube.
As shown in Figure 1, at cold wind by after heat exchanger tube, what produce by boasting is hot blast, therefore, at the other end relative to blast microswitch 4 of heat exchanger tube, also namely has one end of hot blast process, is provided with temperature controller 5.
When axial flow blower 2 normally works, the temperature that temperature controller monitors near heat exchanger tube 1 is in normal range (NR), and Iganition control system 3 normally works.
When axial flow blower because of fault is out of service or burner because of other reasons; the temperature causing temperature controller to monitor near heat exchanger tube 1 is too high; such as one when exceeding default threshold value; exemplary; when the temperature that temperature controller monitors meets or exceeds 90 DEG C, temperature controller 5 sends a signal to Iganition control system 3, and gas valve is power-off immediately; out of service, protection warm-air drier.
As can be seen here, being combined of blast microswitch and temperature controller, effectively ensures the safety in utilization of gas warm-air machine more.
In the utility model, between heat exchanger tube and axial flow blower, be provided with blast microswitch, and be provided with temperature controller near heat exchanger tube, by the duty of blast microswitch monitoring axial flow blower, simultaneously by the temperature near temperature controller monitoring heat exchanger tube.The present embodiment monitors combustion system by above-mentioned two kinds of modes simultaneously, and links with Iganition control system, protects combustion system, substantially increases life-span and the security of burner.
The foregoing is only preferred embodiment of the present utility model; and be not used in restriction the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
