Abstract
The invention provides a high-rate burner capable of adjusting the air inlet speed in order to solve the problem that the existing burner is incapable of accurately adjusting the mixing ratio between natural gas and air. A rotatable sleeve is sleeved outside a combustion cylinder; air inlets corresponding to the positions of the air inlets on the combustion cylinder are formed on the sleeve; and a driving mechanism capable of rotating the sleeve to adjust the size of air channels is connected to the sleeve. The invention can effectively improve the situation about the mixed combustion of natural gas and air under various conditions of air flow and achieve the stable combustion no matter what the air flow is, thus guaranteeing the quality stability of heat treatment products.
Description
Technical field
The present invention relates to industrial gas furnace field, specifically for the burner of industrial gas furnace.
Background technology
The cartridge type high combustion rate burner that existing heat-treatment furnace uses, its structure comprises the air inlet of combustion barrel, natural gas and air.With time by natural air valve and on air duct mounted valve control the two flow, size and ratio, but the speed that can not regulate air to enter.While using this burner, because air cannot effectively be adjusted its speed after entering combustion barrel, therefore also just cannot accurately regulate natural gas and the air mixed proportion in combustion barrel, realize meticulous control, in the time that burner underload is worked, this problem is especially outstanding.
Summary of the invention
The present invention is intended to can not accurately regulate for existing burner the problem of natural gas and air mixed proportion, a kind of high combustion rate burner with air valve is provided, can effectively improve the problem of natural gas and air mixed combustion under different air mass flow situations, no matter uninterrupted all can be realized smooth combustion, thereby has ensured the quality stability of heat treated article.
For achieving the above object, the technical solution used in the present invention is as follows:
The high combustion rate burner of adjustable air intake velocity, comprise the air inlet on combustion barrel, natural gas air inlet, combustion barrel, it is characterized in that: rotating sleeve of combustion barrel overcoat, sleeve is provided with the air admission hole corresponding with air inlet position on combustion barrel; Sleeve is connected with and makes it rotate to regulate the transmission mechanism of air duct size.
Described transmission mechanism is made up of handle, crank, connecting rod, and handle is connected with the rotational pin of crank, and crank is flexibly connected with sleeve through connecting rod.
Beneficial effect of the present invention shows:
High combustion rate burner with air valve needn't be installed separately air valve on air hose, and structure is relatively compacter.Regulate air mass flow by the area that regulates air duct, the speed that makes air enter combustion barrel keeps maximum constant, improves the mixed combustion of the interior natural gas of combustion barrel and air.The problem that can effectively improve natural gas and air mixed combustion under different air mass flow situations, no matter uninterrupted all can be realized smooth combustion, makes the work of burner underload more stable, thereby has ensured the quality stability of heat treated article.

Detailed description of the invention
The present invention as shown in drawings, the rotating sleeve 2 of combustion barrel 1 overcoat of cartridge type high combustion rate burner using at heat-treatment furnace.On sleeve, have and air admission hole orientation onesize with combustion barrel, air flows in combustion barrels and mixes, burns with natural gas through these apertures.
Air inlet is by regulating air inlet hole (on sleeve) and the size of both laps of air inlet (on combustion barrel) to control.Therefore with sleeve supporting also should have a corresponding transmission mechanism, sleeve is rotated, to realize the switching in two holes with respect to combustion barrel.
It comprises handle 8, crank 6, connecting rod 5, and handle is connected on the rotational pin 7 of crank, and the crank other end is flexibly connected with connecting rod 5, and the other end of connecting rod is connected with the engaging lug 3 on sleeve.Handle 8 is with moving sleeve 2 to turn an angle by rotational pin 7, crank 6, connecting rod 5, engaging lug 3, and the air admission hole on sleeve 2 overlaps with the air inlet on combustion barrel, and air enters combustion barrel smoothly.Operating grip 8, to different angles, can make aisle spare diminish, until the aperture on combustion barrel is hidden completely gradually.
Sleeve 2 and the transmission mechanism thereof of above embodiment are exactly the air valve of high combustion rate burner.Can control to adjust the air mass flow of high combustion rate burner.
Operating procedure of the present invention and using method are as follows:
When work, by turning handle 8, be with moving sleeve 2 to turn an angle by axle 7, crank 6, connecting rod 5, ear 3, the aperture on sleeve 2 overlaps with the aperture on combustion barrel, and air enters combustion barrel smoothly.
Arrive diverse location (8-8a) by turning handle, drive crank (6-6a), engaging lug (3-3a), adjust gradually air duct area by diminishing, until the aperture on combustion barrel is hidden completely.
Claims (1)
