Abstract
The utility model discloses a flame blowing-off nozzle device which mainly comprises a heating head (2), a heating nozzle (3), an auxiliary fire hole (4) and a main fire hole (6), wherein the heating head (2) is connected with the heating nozzle (3) through a thread, the auxiliary fire hole (4) is close to the main fire hole (6) on the front end of the heating head (2); when a fuel-air mixture (1) passes through the auxiliary fire hole (4), due to larger resistance loss, the flowing speed of the auxiliary fire hole (4) is less than that of the main fire hole (6), a flame stabilizing ring (5) is formed; and flame of the auxiliary fire hole (4) heats the root of the flame of the main fire hole (6), thus the capacity of preventing flame blowing off by the main fire hole (6) is increased.
Description
Technical field
The utility model relates to a kind of anticreep fire-fighting and chews device, belongs to steel plate preheating technology field.
Background technology
At present, in steel plate preheating technology field, usually adopt cutting torch-type flame nozzle and nozzle type flame nozzle.Cutting torch-type flame nozzle is too high because of flame intensity, and it is comparatively sparse to distribute, and has affected the uniformity of steel plate preheating; Nozzle type flame nozzle is chewed with fire hole and is formed by heating head, heating, when flame when nozzle burns because pressure is excessive, easily produces and take off fiery phenomenon.
The utility model content
For overcoming the deficiencies in the prior art, the utility model provides a kind of anticreep fire-fighting to chew device, and the utility model has improved the fiery limit of taking off of flame, can effectively prevent the anti-avulsion fire, and is easy to produce and assembling, has improved production efficiency.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of anticreep fire-fighting of the utility model is chewed device, and characteristics are: the utility model mainly chews, assists fire hole and main fire hole to form by heating head, heating.
As a kind of preferred version of the present utility model, heating head and heating are threaded connection between chewing, in the front end of the heating head place near main fire hole, and the auxiliary fire hole of new increase.
Compared with prior art, distinguishing feature of the present utility model is: by the auxiliary fire hole of front end increase at heating head, can make flame form a flame stabilization ring at heating head, improved the fiery limit of taking off of flame, and the flame of auxiliary fire hole has heated the flame root of main fire hole, has improved the ability of the anti-anti-avulsion fire of main fire hole.
Description of drawings
Fig. 1 is the stereogram that a kind of anticreep fire-fighting of the utility model is chewed device
Fig. 2 is the cut-away view that a kind of anticreep fire-fighting of the utility model is chewed device
Fig. 3 is the profile that a kind of anticreep fire-fighting of the utility model is chewed device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments; further specify the utility model; but the utility model is not limited to these embodiments, any on the utility model essence spirit improvement or substitute, still belong to scope required for protection in the utility model claims.
In the present embodiment, see also shown in diagram 1 and the diagram 2, a kind of anticreep fire-fighting of the utility model is chewed device, mainly chewing (3), auxiliary fire hole (4) and main fire hole (6) by heating head (2), heating forms, heating head (2) is chewed (3) by screw thread and is connected with heating, auxiliary fire hole (4) is in the place of the close main fire hole (6) of front end of heating head (2).
In the present embodiment, see also shown in the diagram 3, a kind of anticreep fire-fighting of the utility model is chewed device, when combustion gas-air mixture (1) is passed through auxiliary fire hole (4), because drag losses is larger, the flow velocity of auxiliary fire hole (4) is lower than main fire hole (6), and forms flame stabilization ring (5), the flame of auxiliary fire hole (4) has heated the flame root of main fire hole (6), has improved the ability of the anti-anti-avulsion fire of main fire hole (6).
Claims (1)
1. an anticreep fire-fighting is chewed device, mainly chewing (3), auxiliary fire hole (4) and main fire hole (6) by heating head (2), heating forms, it is characterized in that: heating head (2) and heating are chewed between (3) and are threaded connection, and auxiliary fire hole (4) is in the place of the close main fire hole (6) of front end of heating head (2).
