Abstract
The utility model relates to a novel hanging sheet of an inner barrel of a preheater. A hanging sheet body is an arc-shaped folding plate; connecting plates are arranged at the upper end and the lower end of the hanging sheet body; the connecting plate at the upper end of the hanging sheet body is positioned on the outer side of an arc of the hanging sheet body; the connecting plate at the lower end of the hanging sheet body is positioned on the inner side of the arc of the hanging sheet body; the upper surface and the lower surface of each connecting plate are respectively level with the upper surface and the lower surface of the hanging sheet body; a vertical groove is formed in the middle of each connecting plate; each vertical groove penetrates in the whole corresponding connecting plate in the thickness direction; two side plates are respectively arranged on the left side and the right side of the hanging sheet body; grooves are formed in the connecting plates and the hanging sheet body; and the width of each groove in the radial direction of the arc of the hanging sheet body is slightly greater than or equal to the thickness of a connecting plate. The single hanging sheets can be combined to form the complete inner barrel of the preheater, the shortcoming that the traditional inner barrel of the preheater is formed by combining different types of hanging sheets is overcome, the number of manufacturing molds and the number of reserve parts of a using unit are minimized, and the economic benefit is greatly increased.
Description
Technical field
The utility model relates to a kind of lacing film, relates in particular to a kind of cement producing line hanging piece for inner barrel of preheater.
Background technology
Preheater is the equipment that carries out material preheating on new type nonaqueous cement production line.Material is heated after being met with thermal current from bottom to top in the process moving downward by the feeding of preheater top, separated by centrifugal action with after cylindrical shell collision with thermal current, enters next stage preheater by self gravitation.
The object that inner core is set in cyclone cylinder is to improve the separative efficiency of material and thermal current, reduces the unnecessary circulation of granular material between cyclone cylinders at different levels.
Common inner tube structure has two kinds of monoblock type and plate-hung types, the operation easier that monoblock type inner core is made, installed and changes is large, need cutting kiln tail outer cylinder body and insulated pouring layer, just can carry out the operation of tearing open and filling of inner core, and the localized burn of inner core or mechanical failure, all its whole inner core must be changed, therefore burst manufacture, burst transport, field-installed plate-hung type inner cylinder become the first-selection of design.
Existing plate-hung type inner cylinder adopts the lacing film of number of different types to be put together more, and buying and the management cost of production, installation, working service and the standby redundancy of lacing film are remained high, and the waste causing therefrom can not be ignored.Meanwhile, the structure of existing lacing film cause its articulate part be generally exposed to high temperature, high dust in adverse circumstances, make the mounting part split pole of lacing film fragile, the life-span is short, thereby affects the normal work of inner core.
The working environment of hanging piece for inner barrel of preheater and severe, the drum being surrounded by lacing film is kept apart the swiftly flowing high-temperature high dust air-flow in outside in cylinder, and lacing film is subject to strong abrasive wear all the time, generally general less than of the life-span of lacing film 1 year.
Under current technical conditions, the material of lacing film is substantially definite, and each supplier's material difference can be ignored substantially.Therefore, the quality of lacing film configuration design has great meaning for the installation of lacing film and the raising in service life.
Utility model content
Technical problem to be solved: provide a kind of hanging piece for inner barrel of preheater simple in structure, easy to use for above problem the utility model, just can be combined into a complete preheater inner barrel by single a kind of lacing film, make the kind of lacing film be reduced to minimum, for production and the use of plate-hung type inner cylinder are provided convenience, the structural design of lacing film makes the part that articulates of lacing film be surrounded by lacing film simultaneously, avoid the impact of extraneous adverse circumstances, improved the reliability at this place, reduced design difficulty.
Technical scheme: provide a kind of Novel pre-heater inner core lacing film in order to overcome the above problems the utility model, lacing film body is arc flap, be connecting plate in the upper and lower side position of lacing film body, upper end connecting plate is positioned at the outside of the circular arc of lacing film body, lower end connecting plate is positioned at the inner side of the circular arc of lacing film body, the upper and lower surface of connecting plate is concordant with the upper and lower surface of lacing film body respectively, the centre of connecting plate has vertical slot, vertical slot runs through the thickness direction of whole connecting plate, lacing film body each side have a side plate, connecting plate and lacing film body are formed with groove, groove is slightly larger than the thickness that equals a connecting plate at the width of the radial direction of the circular arc of lacing film body.The width of the middle vertical slot of described connecting plate is slightly larger than the thickness of 2 times of side plates.
Beneficial effect:
The disclosed hanging piece for inner barrel of preheater of the utility model just can be combined into a complete preheater inner barrel by single a kind of lacing film, overcome the drawback that traditional preheater inner barrel is combined by number of different types lacing film, thereby the spare unit quantity of mfg. moulding die and applying unit is reduced to minimum, improved greatly economic benefit.Meanwhile, the minimizing of lacing film kind has also facilitated construction operation, has improved operating efficiency.
The smooth smoothness of profile of the utility model lacing film, makes its impact on preheater interior flow field be down to minimum, has reduced the difficulty of lacing film casting processing simultaneously, has improved yield rate, has reduced production cost.
Connecting plate of the present utility model inside does not have gusset, the side plate of lacing film both sides has the effect of gusset, in strengthening lacing film body rigidity, synchronously increase again the thickness of lacing film entirety, wearability and the service life of having improved lacing film, positioning action when side plate also has arranged in dislocation simultaneously; Because the side plate of lacing film both sides has increased again the thickness of lacing film entirety in strengthening body, wearability and the service life of lacing film are improved, therefore the thickness to one that we can the control lacing film body comparatively speaking little value of trying one's best, thus material saved, reduce the weight of lacing film.
Arranged in dislocation between each layer of lacing film of the present utility model, the side of pressing close to that the middle vertical slot of lower one deck lacing film connecting plate is blocked adjacent two lacing films of last layer is locked it naturally, without extra locking device.
