Abstract
The utility model provides a soft connection internal cylinder for cyclone preheaters, which relates to a main member of a cyclone preheater in the technical field of decomposition outside of kiln in cement production. The utility model is characterized in that the rigid whole structure welded by stainless steel plates of a traditional design is changed into a soft connection whole structure composed of a plurality of hanging plates; the hanging plate is rectangular with an arc surface. Besides, the utility model adopts heat resistance steel casting pieces. The internal cylinder of the structure has the advantages of reliable work, long service life, convenient maintenance, short period maintenance, obvious productivity improvement, etc.
Description
The utility model relates to the main member on the precal cination technique key equipment cyclone preheater in the manufacture of cement.Belong to the cement manufacture plant parts.
In cement production process, precal cination technique is a kind of new technology that generally adopts, and it has the significant thermal efficiency, cuts down the consumption of energy, and improves environmental pollution, and cost is low, characteristics such as constant product quality.This technology realizes in cyclone preheater.The main effect of cyclone preheater is to utilize kiln tail waste heat to carry out preheating to processed raw material, makes its intensification make calcium carbonate partly obtain decomposing, to enhance productivity and product quality.Existing structure generally is that multistage (being generally Pyatyi) whirlwind tube by up and down distribution straggly is in series, and its barrel is the whole inner core of corrosion resistant plate welding.When high temperature gas flow enters when doing the spiral ascending motion in the tube along the inner tube wall tangential direction, by the raw material that fall above at air blast effect low suspension among thermal current, and under the effect of airflow centrifugal power, throw to barrel, then landing downwards is to the tremie pipe flap valve, when reaching a certain amount of, spew out into next stage, carry out the heat exchange of higher temperature, hot-air is to lower the temperature step by step from bottom to top.Because the temperature in the tube is up to 850 ℃, and the raw material high-speed motion must make barrel high-temperature oxydation, sulfuration, wearing and tearing and distortion.Therefore, need regularly stop kiln, tear shell open and heat-preserving wall overhauls replacing to inner core.Because above-mentioned working environment and inner tube structure make its life cycle short, change frequent.Maintenance needs large lifting equipment, removes shell and heat-preserving wall, so the fund cost is big, turn(a)round is long, has a strong impact on production efficiency.
The purpose of this utility model is the various shortcoming that exists for the inner core that overcomes above-mentioned employing corrosion resistant plate welding, and providing a kind of can in time change, and maintenance is the new structure inner core very easily.
Above-mentioned purpose is finished by following rigid scheme: change existing employing corrosion resistant plate welding integral rigid structure into branch body structure soft connected type cyclone preheater inner core, it is rearranged by polylith link plate (2), every link plate (2) is a cambered surface rectangle foundry goods, bottom is respectively equipped with hook and hanging groove on it, on the top periphery of the cylindrical chamber of cyclone preheater, be fixed with a plurality of hangers seats (1), one row's link plate (2) on inner core top hangs on the hangers seat (1), below link plate (2) of each row hang over successively on the lower end hanging groove of a link plate (2) of arranging, do not arrange the adjacent link plate in the left and right sides and connect by locking pin (3).
Pai every link plate field interlaced arrangement up and down.
Connect between the every link plate firmly in order to make, have slotted hole in the middle of in the hanging groove of link plate (2) lower end, both sides have open pore, locking pin (3) places in the hanging groove of connection place of two link plates, locking pin is for having the arc strip of two breach (i.e. three boss), the open pore that boss is adjacent with two link plates in the middle of it matches, and the boss at two ends matches with the middle slotted hole of two link plates respectively.
Because this programme changes the integral rigidity structure of corrosion resistant plate welding into be made up of the polylith link plate soft connected type integral body, link plate adopts the exotic material foundry goods, prevents the high temperature scaling loss, and oxidation and distortion have improved the reliability and the property in service life of inner core work.The link plate volume is little, and is in light weight, and installing/dismounting can need not crane gear by manually from cyclone preheater shell manhole door turnover operation.And can utilize when shutting down, carry out local replacing, particularly locking pin at any time and all adopt list structure with three boss, not only connection is tightly solid and reliable, and versatility is good, saves the set-up time.This programme is reliable operation not only, long service life, and also maintenance is convenient, significantly reduces maintenance cost, shortens maintenance duration, improves the running rate of cement kiln, increases the grog output.
Further specifying above-mentioned technology case and embodiment: Fig. 1 thereof below in conjunction with accompanying drawing is soft connected type cyclone preheater inner core assembling schematic diagram; Fig. 2 is the vertical view of Fig. 1; Fig. 3 is the A-A view (being the installation site of locking pin in hanging groove) of Fig. 1; Fig. 4 is the structural representation of locking pin; Fig. 5 is that inner tube structure launches schematic diagram.(1) is the hangers seat among the figure, and (2) are link plates, and (3) are locking pins.Implementing this programme and can adopt following manner, is not only this a kind of mode certainly.Can be by former design, keep inner diameter of steel flue, highly, under the constant prerequisite of basic size, the inner core circumference is divided into 18～20 equal portions, be divided into the 2-3 cribbing by its height, size, make link plate, and with its inner core that unifies.Link plate can adopt the heat resisting steel foundry goods, particularly the optional high-temperature alloy material of operate as normal that is used in more than 900 ℃ under the high temperature of fourth stage level V cyclone preheater inner core is made.The thickness of link plate can increase to 20 millimeters, to prevent its distortion scaling loss, increase friction durability, the gap between link plate and the link plate, arrange the extension connection gap at link plate hanging groove place and the locking program of locking pin up and down and should consider variation of temperature and suitably design, with ensure connect between the link plate reliable.
