The upper end diameter of the described first taper checkerwork cell 2a or the second taper checkerwork cell 2b is greater than lower end diameter, and the xsect of the first taper checkerwork cell 2a or the second taper checkerwork cell 2b is circle or regular hexagon; The described first circular groove 3a and the second positioning boss 4b or the second circular groove 3b and the first positioning boss 4a; The diameter of the first positioning boss 4a or the second positioning boss 4b is less than the diameter 5.5-6.5mm of the first circular groove 3a or the second circular groove 3b when cooperatively interacting, and the height of the first positioning boss 4a or the second positioning boss 4b is less than the degree of depth 4.5-5.5mm of the first circular groove 3a or second circular groove; Described 37 hole checker brick part 1b have 6 second circular groove 3b and 1 second central recess one to have seven second grooves and three second positioning boss 4b; Second groove communicates with six second taper checkerwork cell 2b on the periphery; 3 second circular grooves of the wherein distribution triangular in shape in 6 second circular grooves are corresponding with three second positioning boss respectively; The concentric second taper checkerwork cell is arranged in second groove, and the center of second groove is the center of peripheral six second taper checkerwork cells that are connected; Described 19 hole checker brick part 1a have 6 first circular groove 3a and 1 first central recess one to have seven first grooves and three first positioning boss 4a; Four first taper checkerwork cell 2a of the first circular groove 3a and periphery communicate; The center of the first circular groove 3a is on four first taper checkerwork cell mid-ways of periphery, and 3 first circular grooves of the wherein distribution triangular in shape in 6 first circular grooves are corresponding with three first positioning boss respectively.
Can know from said structure; The utility model is by two kinds of different apertures; But pitch of holes has a certain proportion of, and the checker brick that physical dimension is identical combine under the locating convex block situation identical with groove, requires two parts of molectron under its positioning boss condition consistent with groove, to make up; And to guarantee between the two-part checkerwork cell it is complete intercommunication after the combination; For this reason, this just requires the checkerwork cell intercommunication of each several part structure itself and the degree that communicates wants big, and pitch of holes must be according to a certain percentage under the condition that equilateral triangle is arranged.The utility model has adopted has 19 hole checker brick of the complete checkerwork cell of two circles to be a part; And 37 hole checker brick of the complete checkerwork cell of three circles are arranged is another part, realizes the combination between two portions checker brick under the situation that two portions checker brick are the same in physical dimension and positioning boss is the same with groove.Particularly; On the upper and lower end face of two parts of its combination; One end is that circular groove and 1 central recess of 6 symmetric arrangement constitutes seven grooves; Its effect is the location of realizing checkerwork cell intercommunication and checker brick, and the other end is the projection of three symmetric arrangement, and its effect is wherein three the two-part accurate location of realization checker brick that cooperate in seven grooves.Center for first circular groove of 19 hole checker brick is arranged on the central position of encircling checkerwork cell with the localized first ring checkerwork cell of the checkerwork cell at center and second; Each first circular groove all communicates with four checkerwork cells all around; Arrange six altogether on one circle, add that one at its center has seven first grooves altogether; Center for second groove of 37 hole checker brick is arranged on the central position, hole with the localized second ring checkerwork cell of the checkerwork cell at center, and one second groove communicates with six checkerwork cells all around, and a circle is arranged six, adds that one at center has seven second grooves altogether.The layout of the other end convex platform of two kinds of checker brick parts also is the correspondence position at its groove, and just quantity is each three.Two portions checker brick just can form the combination (see figure 1) of the checker brick of different checkerwork cell numbers in the combination of localized projection and groove like this.The xsect of taper checkerwork cell can be circular, also can be regular hexagon, and proper as long as the pitch of holes that cooperates is selected, the size of taper checkerwork cell can be had change by oneself.Because two kinds of checker brick location of 19 hole checker brick part 1a and 37 hole checker brick part 1b are identical; There are three kinds of situation in mutual combination; Combination separately and mutual combination, the situation of its arrangement is various especially, and this is just for adapting to flowing and provide greatly convenient with heat transfer process in the heat storage.
During practical implementation, the checker brick of above-mentioned two kinds of structures are piled up the back each other up and down form whole heat storage.When high-temperature flue gas stream got into heat storage from the combustion chamber, air-flow entered into conical through-hole with diminishing flow pattern from the wide aperture, progressively quickens to flow out from the small-bore; Before the wide aperture end of one deck checker brick under the entering; Because of the reactive fluid of groove can slow down and mixes mutually; Mutual blended better effects if when especially not running into the boss groove is (because be three boss of seven grooves; Basically seven of groove holes be two-layer blending each other once, and all communicate except that each the checker brick hole of outermost one circle checkerwork cell with two grooves), air-flow can be with a kind of flow-pattern appearance of complicacy like this; Played the effect of regulating gas velocity, after several layers in the checker brick velocity distribution of air-flow will become very evenly; Dust then gets into lower floor checker brick hole because of mass force keeps flow velocity greatly smoothly, avoids the accumulation and the bonding of dust in the groove.Because have many checkerwork cells checker brick (37 hole checker brick part) and the mutual combination of lacking checkerwork cell checker brick (19 hole checker brick part), the mobile of air-flow becomes more complicated, the effect of regulating air-flow velocity is more obvious.The brick that lattices is more outstanding for the effect of its pressure regulation current-sharing for the extremely uneven cold wind of the flow velocity that gets into below the hotblast stove, and the effect that receives is more obvious.Be also pointed out that; The reinforcement that complicated flow field structure must bring heat-transfer effect in the checkerwork cell simultaneously, utilizes the combination of different structure checker brick; Do the checkerwork cell of top checker brick bigger consciously; And that the checkerwork cell of bottom checker brick is done is smaller, is beneficial to balance regenerator heat exchange and the contradiction between the accumulation of heat up and down, lets the heat storage checker brick bring into play its due effect better.
The principle of design of the utility model is; Heat transfer process in the hotblast stove shows; High-temperature area requires the strong and convective heat exchange of heat storage capacity weak (because of there being hyperthermia radiation) relatively, and low-temperature region convective heat exchange ability is eager to excel some and heat storage capacity can be weak relatively.Obviously, adopt the checker brick of same aperture and pitch of holes can not realize above-mentioned requirements.Say from structure, appearance similar and measure-alike checker brick, the aperture is different, pitch of holes is different, and the heat interchanging area of its unit volume is different, and the big more heat interchanging area in aperture is few more under identical pitch of holes, and exchange capability of heat is poor more; And the more little heat interchanging area in aperture is big more, and exchange capability of heat is strong more.Obvious, the former can be used in the high-temperature zone of hotblast stove, and the latter can be used in cold zone.Like this, in same hotblast stove, just must adopt the checker brick of two or more different checkerwork cells, it is very necessary that its mutual combination just seems.Simultaneously, it is complicated that the checkerwork cell channel architecture after the mutual combination of the checker brick in different apertures also is tending towards, for the homogeneity of regulating air velocity distribution and strengthen it and fluid between heat transfer, its effect is very significantly.For this reason, the utility model provides a kind of brick that lattices by two kinds of different brick type structures.
