Abstract
The invention discloses a gas burner of a furnace, which comprises a nozzle and an air blower. The air blower is connected with a frequency conversion control circuit and 'canvas' or a 'metal bellows expansion joint' is used for connecting the nozzle with the air blower. The air blower is directly installed on the ground foundation and monitors a wind pressure switch of the air blower to be replaced with a low speed switch. Inverse signals of 'small wind amount' and 'large wind amount' adopt programmable contacts of a frequency transformer. The gas burner can effectively improve the reliability of burner operation and simultaneously has the advantages of long maintenance period, energy conservation, low production cost and the like.
Description
Technical field
The present invention relates to a kind of gas burner of furnace.
Background technology
At present, burner that sell the market is that flame-thrower nozzle and blower fan are an integral body, air quantity adjusting servo actuator mostly, air-valve and air quantity inverse signal are the mechanical electric contact, vibrate greatly shortcomings such as mechanical electric apparatus reliability of contact difference when its design feature causes the burner operation.Blower fan is at as easy as rolling off a log mechanism wear and the superstructure loosening of regulating air quantity that make of the vibration in when operation, causes burner too much to stop working because of air feed deficiency or air feed; Vibration also can cause ignitor and flame detection device loose shift or the like problem, causes burner ignition difficulties or flame-out; Be used to monitor blower fan pressure switch, wait upon clothes executing agency top and give " little air quantity ", " big air quantity " makes the auxiliary contact of inverse signal because electrical endurance and effect of dust cause burner ignition difficulties and flame-out equally easily.If kiln burner hinders for some reason suddenly when normal operation and stops working, can cause the interior temperature of kiln sharply to descend, from the new liter (10 to the running temperature, can waste a large amount of energy.
Summary of the invention
The objective of the invention is defective, a kind of gas burner of furnace is provided at above-mentioned prior art.
The technical scheme taked of the present invention is to achieve these goals: a kind of gas burner of furnace, comprise nozzle and blower fan, blower fan is connected with the VFC control circuit, connect with " canvas " or " wavy metal telescopic joint " between nozzle and the blower fan, blower fan is directly installed on the basis, ground, the blast switch of fan monitor blower fan is used low speed switch instead, and " little air quantity ", " big air quantity " inverse signal adopts the programmable contact of frequency converter.
Owing to adopt between said nozzle and the blower fan with the soft connection of " canvas " or " metal bellows " split, blower fan is directly installed on the structure on the basis, ground, the vibration that blower fan produces can not passed to the parts except that the blower fan body, facts have proved, avoided the aforementioned problem that causes because of vibration fully, can make the non-maintaining normal operation of blower fan more than 1 year, adopt the mechanical electric contact to change soft electrical contact, effectively reduce the contact malfunction, the chance of tripping, prolonged the service life of contact, the circuit reliability of operation is greatly improved, so the present invention can effectively improve the burner reliability of operation, it is long to have maintenance cycle simultaneously, energy savings, advantages such as low cost of manufacture.
Description of drawings
Fig. 1 is a structural representation of the present invention
The double accompanying drawing that makes an abstract of Fig. 1 wherein.
The specific embodiment
Below in conjunction with accompanying drawing and example the present invention is further described.
As shown in Figure 1, a kind of gas burner of furnace, comprise nozzle 3 and blower fan 1, it is characterized in that: blower fan is connected with VFC control circuit 4, connect with " canvas " or " metal bellows " 2 between nozzle and the blower fan, blower fan is directly installed on the basis, ground, and the blast switch of fan monitor blower fan is used low speed switch instead, " little air quantity ", " big air quantity " inverse signal adopts the programmable contact of frequency converter.
The soft connection of split between nozzle and the blower fan, blower fan is directly installed on the structure on the basis, ground, the vibration that blower fan produces can not passed to the parts except that the blower fan body, avoid the problem that causes because of vibration fully, can make the non-maintaining normal operation of blower fan more than 1 year, adopted the mechanical electric contact to change soft electrical contact, effectively reduce the chance of contact malfunction, tripping, prolonged the service life of contact, the circuit reliability of operation is greatly improved
