Description
Technical field
The utility model belongs to a kind of kiln, relates to a kind of basalt continuous fiber production specifically and uses kiln.
Background technology
The continuous glass fibre production technology has had on a large scale (the single seat tank furnace is produced several ten thousand tons～tens0000 tons per year), and its Technology, furnace construction and equipment technology have been mature on the whole perfect.But for some extraordinary continuous fibres, for example basalt continuous fiber because its raw material moity is different, mineral phase structure is different, causes the Technology of its practical implementation, furnace construction to have than big-difference, even far from each other.
The tradition furnace construction is arch roof construction, the design of many burners basically, and great majority are straight flame burner nozzle structure, and the burner design and installation is in tank furnace Yao Qiang both sides; Because the diathermanous better performances of glass; Glass melting temperature is relatively low, and metal level is all than higher in the tank furnace kiln body, and volumetric ratio is bigger.
The speciality of basalt stone and melt thereof is, becomes to be grouped into the coefficient of dispersion of ore deposit phase composite bigger, causes the viscosity of melt to change greatly, and instability, and the wire-drawing operation temperature range is narrow.Basalt stone contains 10%～15% Fe203, makes melt diathermancy extreme difference, be prone to produce crystallization, and the glass melting temperature of glass is generally at 1380 ℃～1420 ℃, fusiblely basically makes comparatively ideal, as to be fit to continuous glass fibre wire-drawing operation glass melt.The glass melting temperature of basalt stone is 1430 ℃～1500 ℃, even some is up to 1550 ℃, because traditional furnace construction form exists 1, single top arch structure design, is unfavorable for effective formation of each temperature section in the kiln.2, less relatively furnace cavity is prone to take place " string fire " phenomenon during temperature adjustment between each burner.When 3, the flame of side dress updraft burner is out of control, the drawback of the materials for wall of burning opposite kiln wall, the Irish touchstone melt of high-quality, suitable basalt continuous fiber production that very difficult assurance is founded out.
Summary of the invention
The utility model purpose provides a kind of each interval temperature and can accurately control, and kiln is used in the basalt continuous fiber production of the Irish touchstone melt that quality is high, stable.
Speciality to basalt stone; The furnace construction of special makes it to satisfy the temperature regulation process of wide region, and according to the different temperature operation interval; Independent minute adjustment and its temperature value of control; Make in the kiln each point temperature regulate with control process in do not disturb mutually, restriction is because of the viscosity of the Irish touchstone melt that basalt stone composition and ore deposit phase composite difference cause greatly changes, make the raw material that gets in the kiln in the process of founding, try one's best homogenizing, stablize its viscosity.Improve the temperature of fusing as far as possible; The diathermancy that overcomes melt is poor; The recrystallization temperature of avoiding the Irish touchstone melt is interval, and the thermograde in the scientific and reasonable design kiln makes the Irish touchstone melt can either high-quality fusion in kiln; In every section operation interval that the melt flow liquid is passed through, can not produce crystallization again, guarantee to offer high-quality, the stable Irish touchstone melt of basalt continuous fiber wire-drawing operation.
The utility model concrete structure is: it is by the kiln body of heater, charging opening, and discharge port, burner and flue are formed; It is characterized in that, be divided into preheating zone, high-temperature zone in the kiln body of heater successively; There is flue settling section and working district above the preheating zone, on the lateral kiln body of heater in preheating zone charging opening is arranged; Kiln body of heater top is made up of height arch arch and depressed arch arch, and joining with flue is high-temperature zone high arch arch, and what link to each other successively is the depressed arch arch; Settling section high arch arch and working district depressed arch arch, the corresponding zone of high arch arch, high-temperature zone is the high-temperature zone, high arch arch has two row high-temperature zone burners in the high-temperature zone; The high arch of settling section arch correspondence is a settling section, on the high arch of settling section arch, the settling section burner is arranged, and working district depressed arch arch correspondence is the working district; On the depressed arch arch of working district, the working district burner being arranged, is melting channel and operation path between kiln bottom of furnace body and the top, the corresponding flue of the kiln bottom of furnace body place platform that connects material; The kiln bottom of furnace body of working district is lower than the kiln bottom of furnace body between settling section and high-temperature zone, and on the kiln bottom of furnace body of working district, discharge port is arranged, in the kiln body of heater side of working district and the kiln body of heater front between settling section and high-temperature zone the temperature detection mouth is arranged.
The Irish touchstone raw material falls getting in the preheating zone on the platform that connects material from the charging opening input; By hot flue gas it is carried out preheating and fritting, and slug flow provides combustion gas and combustion air to the high-temperature zone through two row high-temperature zone burners; Ratio is regulated and its work output of control; Effectively stop the high-temperature heat flux of high-temperature zone by the depressed arch arch, make the depressed arch arch provide partial heat energy must not get into settling section, basalt stone is in this fusing.Melt after the fusing flows to settling section through melting channel, through the settling section burner melt is carried out boosting again, to reach the further clarification to melt.The Irish touchstone melt that clarification is good gets into the working district through operation path; Provide by the working district burner and to carry out boosting again and make the Irish touchstone melt reach the needed temperature condition of operation; The Irish touchstone melt Conveying that fusing is good is supplied with bushing and is carried out wire-drawing operation to discharge hole for discharge.
The utility model compared with prior art has following advantage;
1, adopts high arch arch, depressed arch arch and the design of flat-top structure combining; For kiln provides novel combined structure design; Effectively suppress the mutually mutual interference of each operation interval when regulating in the kiln, guaranteed each interval accuracy control over temperature, effectively suppress " string fire " phenomenon with controlled temperature.
2, adopt flat-flame burner to be installed in the kiln top, make combustion gas be able to abundant burning, be very beneficial for controlling the mistake residual content of interior combustion gas of kiln and combustion-supporting gas, guarantee that kiln inner pressure and kiln internal combustion atmosphere satisfy the requirement of Irish touchstone melt.
3, the burner design and installation is in kiln body top; Avoided the control of straight flame bad and spall that directly burn kiln wall or melt feed produce pollutes the manufacturability that the Irish touchstone melt forms, for the stably manufactured operation of basalt continuous fiber provides fine Irish touchstone melt.
