Description
[technical field]
The utility model relates to a kind of adjusting device, is specifically related to a kind of device regulating firing atmosphere.
[background technology]
Nowadays, firing firing of product is be positioned in kiln by ceramic body to fire, kiln generally comprises kiln body, combustion system, control system etc., and combustion gas and AIR Proportional input passing ratio valve to control in combustion system, combustion system selects proportioning valve to ensure, and combustion gas and air effectively regulate according to the ratio set, it not only can ensure the automatic control of temperature, and also ensure that the automatic control that kiln atmosphere is stable.Under normal circumstances, after the air-fuel ratio (namely air and fuel input ratio) of proportioning valve is determined, be difficult to carry out adjustments change to air-fuel ratio.
In actual production process, fire product in sintering procedure, adopt which kind of firing atmosphere, can determine according to the physical reaction situation of burning till each stage in the composition of formula for a product Raw and sintering procedure.If fire product when only needing a kind of firing atmosphere in sintering procedure, kiln combustion system adoption rate valve can reach requirement completely.If but fire product and need to make a change firing atmosphere in sintering procedure, being difficult to regulate and changing because of proportioning valve air-fuel ratio, this will bring a lot of inconvenience to sintering procedure, affects firing of product.
[summary of the invention]
Main purpose of the present utility model is to separate the problems referred to above, and provide a kind of and can regulate the device changing firing atmosphere in sintering procedure, the device of this adjustment firing atmosphere has simple, the easy to operate advantage of structure.
A kind of device regulating firing atmosphere that the utility model provides, comprising: gas pipeline, air duct, bypass duct,
Described gas pipeline is provided with magnetic valve, proportioning valve, branch road hand-operated valve successively along combustion gas input direction,
Described air duct is connected by connecting pipe with proportioning valve,
Described bypass duct is located on described gas pipeline, and one end of this bypass duct is fixed between magnetic valve and proportioning valve, and the other end is fixed between described proportioning valve and branch road hand-operated valve, and described bypass duct is provided with control valve.
Especially, described proportioning valve is proportional pressure control valve.
Especially, described control valve is electric control valve.
Especially, described control valve is manual modulation valve, and this manual modulation valve is provided with scale.
Compared to prior art, a kind of device regulating firing atmosphere provided by the utility model, is coordinated the firing atmosphere regulating and change in kiln, has the advantage that structure is simple, easy to operate with proportioning valve by control valve.
[accompanying drawing explanation]
Fig. 1 is a kind of structural representation regulating the device of firing atmosphere of the utility model.
[detailed description of the invention]
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further described.
Refer to Fig. 1, electromagnetic deceleration device of the present utility model, comprising: gas pipeline 10, air duct 30, bypass duct 20,
Described gas pipeline 10 is provided with magnetic valve 11, proportioning valve 12, branch road hand-operated valve 13 successively along combustion gas input direction,
Described air duct 30 is connected by connecting pipe 31 with proportioning valve 12, and the gas pressure that described air duct 30 inside produces passes to proportioning valve 12 by connecting pipe 31,
Described bypass duct 20 is located on described gas pipeline 10, and one end of this bypass duct 20 is fixed between magnetic valve 11 and proportioning valve 12, and the other end is fixed between described proportioning valve 12 and branch road hand-operated valve 13, and described bypass duct 20 is provided with control valve 21.
Especially, proportioning valve 12 adoption rate pressure-control valve, air duct 30 is communicated with outside air by blower fan, when kiln does not work, blower fan is in closed condition, and branch road hand-operated valve 13 cuts out, make air pressure in air duct 30 be zero-pressure, proportioning valve 12 is in closed condition simultaneously; Otherwise fan starting, then form air pressure in air duct 30, now proportioning valve 12 can realize automatic unlatching under the effect of air pressure, and after opening branch road hand-operated valve 13, combustion gas and air enter burner automatic combustion.
Especially, described control valve 21 adopts electric control valve, in time working, the control system of kiln sends signal, after electric control valve receives the signal that control system sends, enter duty, regulate the intake of bypass duct 30 combustion gas, after end-of-job, control the decorum and send signal to electric control valve, electric control valve cuts out after receiving signal, prevents the intake of bypass duct 30 combustion gas.
Especially, described control valve 21 is the graduated manual modulation valve of band, and in time working, open manual modulation valve, the scale manually on control valve controls the intake of bypass duct 30 combustion gas, after end-of-job, closes manual modulation valve.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to the utility model claims.
