The first-row hanging pieces comprise first-row hanging pieces I and first-row hanging pieces II. The first-row hanging pieces I and the first-row hanging pieces II are alternately arranged in the circumferential direction. The first-row hanging pieces II is connected to a top cover of a cyclone in a lapping mode through a quadrangular boss structure and fixed to a fixed base on the top cover of the cyclone through bolts, and the first-row hanging pieces I and the first-row hanging pieces II are connected through hooks. The middle hanging pieces are connected with adjacent hanging piece of an upper layer and a lower layer through hooking corners of four corners. Adjacent hooking corners of two adjacent tail-row hanging pieces are fixed through locating pins. The hanging pieces are suitable for the cyclones with different sizes in cement production lines with different scales; inner cylinders formed in combination are stable and firm and can effectively guarantee good gas-solid separation efficiency and heat exchange efficiency of the cyclones; the hanging pieces can be maintained, disassembled and replaced conveniently, and stable and continuous operating of the industrial cement production lines can be guaranteed as much as possible.
Description
Technical field
The utility model belongs to cement industry and manufactures field, specifically, relates to a kind of connected mode of internal barrel of preheater cyclone barrel lacing film.
Background technology
Cyclone cylinder inner core is widely used in the firing system of cement industry, and its Main Function is the swirl strength of strengthening in cyclone cylinder, strengthens rate of heat exchange, improves resolution ratio.By carrying additionally inner core, can effectively regulate gas solid separation and the heat exchange effect of cyclone cylinder.A lot of cement plants inner core lacing film used because material differs, not etc. each side factor of the coefficient of expansion, the phenomenon such as collapse easily deforms, damages, ftractures, drops, this will cause operating mode in preheater windspout barrel to change, gas solid separation efficiency is had a strong impact on, heat loss increases, and even stops up cyclone cylinder tremie pipe.The assembly heat-resistant antifriction poor performance of some inner cores, entirety is firm not firm, and assembly is too heavy, connected mode is complicated, changes too trouble when lacing film damages, and has affected the normal of cement production enterprise and has produced continuously.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of fixed, change conveniently, the internal barrel of preheater cyclone barrel lacing film connected mode of long service life.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of connected mode of internal barrel of preheater cyclone barrel lacing film, comprise first row's lacing film, middle lacing film, tail row lacing film, and be arranged in order from top to bottom, described head arranges lacing film and comprises first row lacing film I and first row's lacing film II, first row lacing film I and first row's lacing film II along the circumferential direction alternately arrange, described first row's lacing film II is overlapped on cyclone cylinder top cover by a tetragonal boss structure, and is secured by bolts on the holder of cyclone cylinder top cover.
Described head arranges lacing film I and is connected by hook with first row's lacing film II.
Described in the middle of lacing film by the cheicers at four angles lacing film adjacent with levels, be connected, the connected mode that adjacent lacing film articulates by cheicers, fixed and also change convenience, be of value to the production of cement production enterprise steady and continuous.
Described tail row lacing film is the next row lacing film of whole cyclone cylinder inner core, every tail row lacing film be each side provided with a barb upwards, the adjacent cheicers of adjacent two tails row lacing film is fixed by alignment pin.
Described alignment pin is three limit type structures of the with groove made by chrome-nickel material.
Described tail is arranged lacing film and is comprised tail row lacing film I and tail row lacing film II, and tail row lacing film I is alternately connected with tail row lacing film II, and tail is arranged lacing film I and tail row lacing film II length difference equates with first row lacing film I and the first length difference of arranging between lacing film II.
Described first row's lacing film, middle lacing film, tail row lacing film are made by casting chrome-nickel steel, and lacing film heat-resistant antifriction performance is good, and in system process and the good situation of crude fuel, the life-span can reach about 2 years.
The utility model is arranged the Proper Match combination of lacing film, middle lacing film, tail row lacing film three class lacing films by head, form the cyclone cylinder inner core of different race diameters and different length, can adapt to the use of the cyclone cylinder of different size in different scales cement producing line, and the inner core combining is firmly stable, can effectively guarantee gas solid separation efficiency and heat exchange efficiency that cyclone cylinder is good, and it is convenient that maintenance changes lacing film, can guarantee the stable continuous service of production line as far as possible.

The specific embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described further.
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, a kind of connected mode of internal barrel of preheater cyclone barrel lacing film, comprise first row's lacing film, middle lacing film, tail row lacing film, and be arranged in order from top to bottom, described head arranges lacing film and comprises first row lacing film I1 and first row's lacing film II2, first row lacing film I1 and first row's lacing film II2 along the circumferential direction alternately arrange, described first row's lacing film II2 is overlapped on cyclone cylinder top cover 6 by a tetragonal boss structure, and by bolt 7, be fixed on the holder 8 of cyclone cylinder top cover 6, described head arranges lacing film I and is connected by hook with first row's lacing film II, in the middle of described, lacing film 3 is connected by the cheicers at four angles lacing film adjacent with levels, formed the middle main body ring layer of inner core, during design, can adjust by the length of lacing film 3 in the middle of changing the overall length of whole inner core, to meet the needs of various processes.
As shown in Figure 1 and Figure 5, tail row lacing film is the next row lacing film of whole cyclone cylinder inner core, tail row lacing film comprises tail row lacing film I4 and tail row lacing film II5, tail row lacing film I4 is alternately connected with tail row lacing film II5, and tail is arranged lacing film I and tail row lacing film II length difference equates with first row lacing film I and the first length difference of arranging between lacing film II.Every tail row lacing film be each side provided with a barb upwards, the adjacent cheicers of adjacent two tails row lacing film is fixing by chrome-nickel alignment pin 9, during use, groove blocks the cheicers of adjacent tail row lacing film downwards, make last lap lacing film solid and reliable, while changeing lacing film, only need take off alignment pin 9, just can dismantle easily and fast each layer of lacing film, by changing spare part, on the impact of system operation, drop to minimum.
