Abstract
The utility model relates to an automatic coal gas butt joint for a gas bell-type furnace, which comprises an upper joint and a lower joint. A pressing block is mounted on the upper joint through a compression spring and is capable of vertically moving relative to the upper joint; a conical guide head and a sealing ring are arranged on the lower joint; and flanges connected with a coal gas pipe are arranged on the upper joint and the lower joint. As the lower joint is mounted on a base of the bell-type furnace, the upper joint is fixed onto a heating mantle through a pressing plate, the upper joint is rapidly and tightly pressed on the lower joint through the conical guide head during descent of the heating mantle, manual assembly and disassembly are omitted, connecting reliability and tightness are improved, and convenience is brought for realizing automation of heat treatment. Besides, the automatic coal gas butt joint is widely applied to bell-type furnaces in various large steel mills.
Description
Technical field:
The utility model relates to a kind of interconnection technique of gas line, relates in particular to a kind of coal gas joint of combustion gas bell furnace.
Background technology:
In recent years, along with market to the sheet material of ferrous metal and non-ferrous metal clean annealing, the continuous increase of band demand, and these sheet materials, band in production process often with the form transmission of rolling; Its thermal treatment mainly relies on bell furnace for a long time, in heat treatment process, in order to guarantee the temperature in the stove, must heat; Bell furnace mostly adopts the mode of coal gas heating at present; Because bell furnace needs heating mantles and cooling cowl to exchange once at a heat treatment cycle, when moving heating mantles, must the coal gas joint be shed, because the coal gas joint is installed in the side of heating mantles; About 15 kilograms of the weight of joint; Adopt relatively difficulty of artificial mounting or dismounting, the time of connection and dismounting is longer, has influenced heat treated robotization at every turn.
The utility model content:
The purpose of the utility model has overcome deficiency of the prior art exactly, and a kind of coal gas automatic butt joint of rapid mounting or dismounting is provided.
The utility model is to realize like this; A kind of combustion gas bell furnace comprises lower sub with coal gas automatic butt joint, it is characterized in that: through compression spring briquetting is installed in the said top connection; Said briquetting can move up and down with respect to said top connection; The taper guide head is arranged in said lower sub, and said lower sub is provided with sealing-ring, and the flange that connects gas line is arranged in the lower sub on said.
The utility model compared with prior art has following advantage:
Because lower sub is installed on the base of bell furnace; Top connection is fixed on the heating mantles through pressing plate; In the downward process of heating mantles, rapidly top connection is pressed in the lower sub through the taper guide head, need not artificial mounting or dismounting; Improve the safety and the stopping property that connect, provide convenience for thermal treatment realizes robotization.
Description of drawings:
Fig. 1 is the structural representation of the said combustion gas bell furnace of the utility model with coal gas automatic butt joint
⒈ flange ⒉ briquetting 3. compression spring ⒋ top connection ⒌ guide head ⒍ lower sub ⒎ sealing-rings
Embodiment:
Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model, and all technical schemes that are equal to also belong to the category of the utility model, and the scope of patent protection of the utility model should be limited each item claim.
As can beappreciated from fig. 1; A kind of combustion gas bell furnace comprises lower sub 4 and 6 with coal gas automatic butt joint, it is characterized in that: through compression spring 3 briquetting 2 is installed in the said top connection 4; Said briquetting 2 can move up and down with respect to said top connection 4; In said lower sub 6, taper guide head 5 is arranged, said lower sub 6 is provided with sealing-ring 7, in the lower sub 4 and 6 flange 1 that is connected gas line is arranged on said.
Top connection 4 is fixed on the heating mantles through pressing plate 2, and lower sub 6 is installed on the base of bell furnace.
