Detailed description of the invention
The positive taper dry powder and mortar movable material storage tank with isolation-proof device as shown in Figures 1 to 3, mainly comprisesMortar jar tank body 1, blowing cone 2 and discharging opening 3, blowing cone 2 is fixedly connected on mortar jar tank body 1 timeEnd, discharging opening 3 is arranged on the lower end of blowing cone 2, and the arranged outside of blowing cone 2 has fixed support 4,The inner side of blowing cone 2 is also provided with isolation-proof device; Isolation-proof device is mainly by lower sandpipe 5, blanking plate 6Form with blanking hole 7, blanking plate 6 is horizontally set on the upper end of discharging opening 3, and blanking hole 7 is arranged on blankingOn plate 6, the sidewall of lower sandpipe 5 is fixedly connected on the inwall of blowing cone 2, and the lower end of lower sandpipe 5 is fixedBe connected on blanking hole 7. Can make like this material sandpipe 5 blankings from having more, realize multiple spot blanking,Improve blanking velocity, prevent segregation phenomenon.
The quantity of wherein descending sandpipe 5 is five, and in lower sandpipe 5, one is arranged on the middle part of blanking plate 6, underIn sandpipe 5, all the other four are symmetrical arranged around, in lower sandpipe 5 between all the other four lower sandpipes 5 adjacentAngle is 90 °. In lower sandpipe 5, the length of one is 100~150mm, all the other length of four in lower sandpipe 5Degree is 1000~1200mm. In lower sandpipe 5, all the other four is 40 °~60 ° with the angle of blanking plate 6;Above-mentioned data are to learn through experimental data many times by inventor, can fully ensure so lower sandThe fossaperturate forming on pipe 5 can be evenly distributed in material bed upper, because material is in lower sandpipe 5 places blankingTime, the top of lower sandpipe 5 can form fossaperturate, and material is taked the mode of many fossaperturates blanking like this,Can in blanking, indirectly play the effect of the secondary mixing of material, improve the mixture homogeneity of material,Effectively prevent the phenomenon of segregation. The upper end of lower sandpipe 5 is also provided with hand flow regulating valve 8; Like thisDesign be the flow in order to regulate each lower sandpipe 5, the even whereabouts of realizing material. Manually Flow-rate adjustmentThe outside of valve 8 is also provided with protective cover 9. The outside of blowing cone 2 is also provided with access hole 10. Discharging opening 3Lower end be also provided with mixer 11; Can align like this to fall in taper dry powder and mortar movable material storage tankMaterial carries out secondary agitation, improves the mixing uniformity of material. The outside of mortar jar tank body 1 is also provided with and climbsLadder 12. Like this can handled easily personnel climb up detection and inside that blanking is carried out in the upper end of mortar jar tank body 1Maintenance.
As shown in Figure 4 be that traditional positive taper dry powder and mortar movable material storage tank does not arrange anti-segregation conventionallyDevice, the material in mortar jar tank body 1 all can be through discharging opening 3 dischargings, and operating personnel need conventionallyClimb up cat ladder 12, arrive the top view blanking situation of mortar jar tank body 1, can find out material bed appearance oneIndividual fossaperturate, large yellow sand, the flyash etc. of particle can preferentially tumble fossaperturate discharge conventionally, and particle is littleDischarge after the meeting, cause material component to separate, occur very serious segregation phenomenon.
As shown in Figure 5 be to adopt the positive taper dry powder and mortar movable material storage tank of isolation-proof device, work as useAfter isolation-proof device, operating personnel need to climb up cat ladder 12 conventionally, arrive the top view of mortar jar tank body 1Blanking situation, can find out on material bed and occur multiple fossaperturates, multiple fossaperturates are evenly distributed in thingOn the bed of material, can effectively cut off the blanking of material like this, when material falls from fossaperturate,Have individual motion downtrend, the secondary that can increase like this storeroom mixes, and prevents the phenomenon of segregation,The globality that realizes material evenly falls, and operating personnel can regulate every lower sand according to the size of fossaperturateManage the hand flow regulating valve 8 of 5 upper ends, control the lower sand flow amount of every lower sandpipe 5, ensure each depressionMouth falls uniformly, improves the quality of overall material.
Whether we,, to adopting isolation-proof device to make the experiment of contrast property, first adopt the same manner to stir100 tons of good materials, are placed in the dry powder and mortar tank that does not adopt isolation-proof device 50 tons of placements by 50 tonsHaving adopted in the dry powder and mortar tank of segregation device, carry out blanking experiment, specific experiment result data is as following table:
Do not adopt isolation-proof device | Adopt isolation-proof device | Standard | |
Modulus of fineness | 4.0 | 2.4 | 2.3~2.5 |
Mixture homogeneity (Cv) | 12.0 | 4 | ﹤7.0 |
Voidage (%) | 7.0 | 4.5 | ﹤5.0 |
Modulus of fineness, is a kind of index that represents that in concrete sand, stone fineness mix, and is generally movingThe modulus of fineness of the material being stirred in dynamic formula storage tank, between 2.3~2.5, is not installed after isolation-proof deviceIt is 4.0 that discharging records modulus of fineness, has produced serious material segregation phenomenon, by installing after isolation-proof device,The modulus of fineness of material is 2.4, meets the requirements; Mixture homogeneity is inhomogeneity for detecting mixing of materialsParameter, the mixing of materials uniformity standard being stirred, below 7.0, is not installed after isolation-proof device materialAfter discharging, record mixture homogeneity and reach 12.0, occurred serious feed separation phenomenon, after employing, measure mixedClose the uniformity and reached 4; Voidage, refers to voidage and whole material bed body between particle and particleLong-pending ratio, the voidage standard of the material being stirred, below 5.0, is not used the voidage of isolation-proof deviceReach 7.0, after employing isolation-proof device, the voidage of material has reached 4.5.
The one that is illustrated in figure 6 blanking plate 6 is preferentially improved, and blanking plate is arranged to the sheet material knot with arcStructure arranges multiple sieve apertures 13 on arc blanking plate 6, can ensure like this to there will not be on blanking plate 6 long-pendingThe phenomenon of material, has saved manually and has cleared up buildup by access hole 10.
Although more than described the specific embodiment of the present invention, those skilled in the art should manageSeparate, these only illustrate, and can make various changes or modifications to present embodiment, and do not deviate from thisPrinciple and the essence of invention, protection scope of the present invention is only limited by appended claims.
