Description
Technical field
The utility model belongs to cement manufacture plant technical field, particularly a kind of ceramic inner barrel hanging sheet.
Background technology
Preheater is equipment new type nonaqueous cement production line carrying out material preheating, primarily of part compositions such as cyclone cylinder, connecting pipe and air valves.Wherein, in order to improve the separative efficiency of material and thermal current, reducing the unnecessary circulation of granular material between cyclone cylinder at different levels, in cyclone cylinder, being also provided with inner core.
Common inner tube structure has monoblock type and plate-hung type two kinds, the operation easier that monoblock type inner core makes, install and change is large, need cut 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, the difficulty installing and change its inner core is large, high material consumption, costly, the time is long, and the operating rate of manufacture of cement is low.For the defect of monoblock type inner core, occurred that inner tube structure adopts hook to be connected by lacing film, but in prior art, the mounting part of lacing film is exposed in corrosive environment, and service life is short, thus affects the normal work of inner core.
Application number be 201220499627.2 utility model patent disclose a kind of ceramic inner barrel hanger for cement kiln preheater structure.This hanging chip structure comprises the consistent front lacing film of structure and rear lacing film, between described front lacing film and rear lacing film, be provided with reinforcement structure, is provided with installing hole at the upper and lower end of described front lacing film, rear lacing film and reinforcement structure.Owing to have employed the material of high temperature resistant, corrosion resistant pottery as inner core lacing film, thus it has good corrosion-and high-temp-resistant performance, substantially prolongs the service life of lacing film.But after connecting between this ceramic inner barrel hanging sheet, lacing film and lacing film do not have space, and when production is carried out, under the temperature in inner core cylindrical shell is in 700-1000 DEG C of operating temperature, ceramic lacing film expanded by heating, extrudes mutually, the situations such as lacing film fragmentation are easily made to occur.Meanwhile, the relation be connected with between levels between this lacing film, can not be in same plane, unfavorable to the flowing of air-flow in inner core.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of ceramic inner barrel hanging sheet, and this hanging chip structure is reasonable in design, is in same plane, is conducive to the flowing of air-flow in inner core after installing between lacing film; Simultaneously after lacing film is installed, between lacing film, leave certain space, thus the situation of the fragmentation generation because of ceramic lacing film expanded by heating extruding can be avoided.
The technical scheme in the invention for solving the above technical problem is:
A kind of ceramic inner barrel hanging sheet, described ceramic inner barrel hanging sheet entirety is in I shape, ceramic inner barrel hanging sheet comprises upper arm, underarm and connects the linking arm of upper arm and underarm, the upper end of linking arm is connected with the center of upper arm lower surface, the lower end of linking arm is connected with the center of underarm upper surface, and upper arm is consistent with the size shape of underarm; The part lower surface of described upper arm being positioned at the both sides of linking arm is provided with groove, and the part upper surface of underarm being positioned at the both sides of linking arm is respectively arranged with fin, and described groove and fin match; The front end face of described upper arm offers two installing holes, two installing holes lay respectively at the both sides of linking arm; The length of described linking arm is slightly larger than the width sum of upper arm and underarm.This ceramic inner barrel hanging sheet is in same plane between lacing film after mounting, is conducive to the flowing of air-flow in inner core; Simultaneously after lacing film is installed, between lacing film, leave certain space, thus the situation of the fragmentation generation because of ceramic lacing film expanded by heating extruding can be avoided.
As preferably, described upper arm both sides are narrow, middle wide; The upper surface of upper arm is flat surface, and the lower surface of upper arm is cambered surface, and the left and right side of upper arm and lower surface are arc transition in junction.Considering that the ceramic inner barrel hanging sheet under HTHP effect can produce thermal expansion in the course of the work, therefore arc transition is set between the left and right side and lower surface of upper arm and the lower surface of upper arm is set to cambered surface, be used for compensate for heat expansion and avoid producing larger bending stress, thus avoid ceramic inner barrel hanging sheet cracked.
As preferably, described underarm both sides are narrow, middle wide; The lower surface of underarm is flat surface, and the upper surface of underarm is cambered surface, and the left and right side of underarm and upper surface are arc transition in junction.Considering that the ceramic inner barrel hanging sheet under HTHP effect can produce thermal expansion in the course of the work, therefore arc transition is set between the left and right side and upper surface of underarm and the lower surface of upper arm is set to cambered surface, be used for compensate for heat expansion and avoid producing larger bending stress, thus avoid ceramic inner barrel hanging sheet cracked.
As preferably, described ceramic inner barrel hanging sheet is formed in one.
The utility model compared with prior art, has the following advantages and effect: this ceramic inner barrel hanging sheet is in same plane between lacing film after mounting, is conducive to the flowing of air-flow in inner core; Simultaneously after lacing film is installed, between lacing film, leave certain space, thus the situation of the fragmentation generation because of ceramic lacing film expanded by heating extruding can be avoided.Simultaneously owing to being adopt pottery for material, thus adopt the inner core of this lacing film lightweight, high temperature resistant, decay resistance is superior, wearability is excellent especially.
