Description

Produce lytag, adobe, roofing tile processing method and device

Technical field: the present invention relates to flyash, be specially and produce lytag, adobe, roofing tile processing method and device.

Background technology: at present, large coal-fired boilers such as existing fuel-burning power plant, heating, producer gas generator produce a large amount of flyash, and through the ash pump of water conservancy ash handling equipment, ash conveying pipe is transported to the ash field.Existing lytag, adobe, roofing tile production technique are that the health moulding is being calcined or leaned on to the flyash of ash field behind the formed at normal temp under keeping warm mode.Its shortcoming is to need to build large-scale storage ash field and complete flyash cooling, pulverizing, water conservancy delivery system, need to take up an area of in a large number, and water loss is huge, and environmental pollution seriously needs huge investment simultaneously; The raw material that it utilized is the flyash of reducing to normal temperature from 900 ℃ of left and right sides high temperature, in the calcination process, the flyash under the normal temperature state is warmed to about 1000 ℃ again, and this mode of production energy dissipation is serious, and the production cost height is unfavorable for the development and use of flyash.

Summary of the invention: the object of the present invention is to provide a kind of simple in structure and low in cost, needn't build large-scale ash, save water source and the energy, free from environmental pollution, technological operation use simple, safe and reliable a kind of production lytag, adobe, roofing tile processing method and device.The object of the present invention is achieved like this: it comprises burner hearth-1, ash bucket 2, fusing assistant adding set 3, guide groove 4, pulverizes mixing section 5, guide groove 6, High Temperature Furnaces Heating Apparatus 7, haydite guide groove 8, haydite shaper 9, adobe guide groove 10, green brick forming machine 11, roofing tile guide groove 12, roofing tile shaper 13, is connected with ash bucket 2 on pulverize mixing section 5, is connected with fusing assistant adding set 3 on pulverizing mixing section 5 left sides, is connected with High Temperature Furnaces Heating Apparatus 7 on pulverizing mixing section 5 right sides; At the output terminal of High Temperature Furnaces Heating Apparatus 7, be connected with haydite shaper 9 or green brick forming machine 11 or roofing tile shaper 13 by haydite guide groove 8 or adobe guide groove 10 or roofing tile guide groove 12; In fusing assistant adding set 3, contain saltpetre or SODIUMNITRATE 9-110kg or rhombspar 10-150kg by mixed flyash per ton; the add-on of fluorite 30-280kg or Wingdale 15-90kg or soda ash 3.5-120kg or saltcake 10-100kg or triphane 5-120kg or barium carbonate 5-80kg borax 5-150kg; enter to pulverize in the mixing section 5 through guide groove and mix with flyash; mix after guide groove 6 enters in the High Temperature Furnaces Heating Apparatus 7 and become soft state or the molten state of melting 1000-1550 ℃ of calcination, the soft flyash that melts state through haydite guide groove 8 or adobe guide groove 10 to haydite shaper 9; produce in the green brick forming machine 11 and be respectively lytag or adobe.The flyash of molten state pours into roofing tile through roofing tile guide groove 12 to roofing tile shaper 13.The flyash of calcination is that 1000-1300 ℃, adobe are that 1000-1300 ℃, roofing tile are 1200-1550 ℃ for the temperature of producing haydite in High Temperature Furnaces Heating Apparatus 7.The invention has the advantages that: utilize 900 ℃ of left and right sides pyritous flyash directly to be warmed to and produce haydite, adobe and roofing tile etc. about 1000-1550 ℃, so this device utilized pyritous flyash heat energy, saved a large amount of energy; The consumption that has saved water conservancy ash handling equipment, pipeline and water resources simultaneously; Save grey construction land in a large number, reduced great amount of investment and environmental pollution, helped the development and use of flyash.
