Description
Technical field
The present invention relates to a kind of kiln additional alarm device, especially a kind of monitoring kiln burner local overheating alarm dress
Put.
Background technology
In the course of work of kiln, the burner combustion chamber hot soak condition of continuous heat supply, and product volume is very
Hardly possible is stablized always, during for instance in the state of the differences such as useful load different size, empty kiln, kiln filling, necessarily causes burner combustion
Room temperature is continually changing.Due to lift repeatedly or repeatedly igniting, extinguishing, make combustion chamber meet fire be constantly in expansion, it is contraction-like
State, when local contraction is inconsistent or more than its material life-span, burner combustion chamber can be ftractureed or even is broken.Due to burner combustion chamber
Build by laying bricks or stones in wall heat insulation layer and temperature is higher, it is difficult to automatic monitoring, be difficult to discover when going wrong, the most of the time is burner
Region kiln body is burnt out, and until panel is by sooting, rubescent or could find when altering fire outward, has now had resulted in massive losses, must
Kiln maintenance must such as be stopped.
Combustion chamber is directly monitored, because of the influence of the factors such as sealing structure, temperature height, it is difficult to design supporting supervising device,
Constantly maked an inspection tour mainly by operative employee at present, labor intensity is big and could find after the kiln wall apparent damage in burner region such as needing.
Kiln wall can typically use the refractory material of different temperatures grade from meeting fire to outside wall, and more outer wall thermal conductivity factor is smaller but resistance to
Temperature is lower, therefore, and when combustion chamber crack occurs, broken, flame can burn out the low insulation material of heatproof, cause to alter
Fire.Our company finds that, when kiln wall is damaged, outside wall temperature can be stepped up by detection, research, temperature occurs altering after fire most
It is high；But combustion chamber just goes wrong, such as it is broken, burner flange temperature can rise in a short time, and is far above normal temperature, in
It is to work out a kind of monitoring kiln burner local overheating warning device of the present invention, is monitored and burnt by round-about way
Chamber region wall temperature, can effectively prevent trouble before it happens.Alarm, promote immediately when temperature anomaly occur and being increased to design temperature
Operating personnel check rapidly respective regions, advanced processing, it is to avoid the state of affairs expands, and reduce loss.
The content of the invention
Present invention aims to solve the deficiencies of the prior art, and provides a kind of one kind can detect burner broken situation, drop in time
The monitoring kiln burner local overheating warning device of low-maintenance difficulty and cost.
To achieve these goals, a kind of multi-functional combustion trial furnace of the invention is adopted the following technical scheme that：
The device includes a burner, burner flange, burner controller, temperature-sensing element；Wherein, burner have ignitor and
Electrode is monitored, burner flange is installed on kiln and is close to outer wall of combustion chamber, burner combustion chamber, burner combustion are provided with around burner
Room is made up of the pipe sleeve of silicon carbide material, and the high alumina in the heat insulation layer for being installed on kiln is additionally provided with outside the pipe sleeve of silicon carbide material
Quality guarantee sheath；Temperature-sensing element 4 is the contact temperature-sensing element being installed on burner flange 2, and temperature signal is passed into burner control
Device 3 processed.
Preferably, separated between the pipe sleeve of silicon carbide material and High-Alumina protective case by high temperature cotton blanket, for sealing and just
In dismounting and replacing.
Preferably, described burner flange is close to burner combustion chamber outer wall, and described temperature-sensing element is cylinder, cylinder
Temperature-sensing element be embedded in temperature in flange and directly near sensing burner combustion chamber.
Preferably, temperature-sensing element can be overtemperature alarm type or measurement temperature type, can also be numerical value display alarm
Type.
As a result of said structure, a kind of monitoring kiln burner local overheating warning device of the invention passes through contact chip
The temperature of burner flange is conducted, and the temperature of contact chip is sensed by temperature-sensing element in real time, when the temperature of contact chip is beyond normal
, now can be timely to burning during scope, then it represents that exception occurs for the temperature at burner, and burner control cabinet is judged as burner broken
Mouth is changed, and further device damage situation generation is prevented, so as to effectively reduce maintenance difficulties and cost.

Embodiment
As Figure 1-Figure 4, a kind of monitoring kiln burner local overheating warning device of the embodiment of the present invention
Including a burner 1, burner flange 2, burner controller 3, temperature-sensing element 4；Wherein, burner 1 have ignitor and
Electrode is monitored, burner flange 2 is installed on kiln 5 and is close to outer wall of combustion chamber, burner combustion chamber 6, burner are provided with around burner 1
Combustion chamber 6 is made up of the pipe sleeve 61 of silicon carbide material, and the thermal insulation for being installed on kiln 5 is additionally provided with outside the pipe sleeve 61 of silicon carbide material
High-Alumina protective case 8 in layer 7；Temperature-sensing element 4 is the contact temperature-sensing element being installed on burner flange 2, and temperature is believed
