Abstract
The utility model discloses a sSodium aluminate solution column flow flat-bottom decomposer, which belongs to the sodium aluminate solution decomposer. The utility model aims at providing a sodium aluminate solution decomposer which has low cost, simple structure and no energy consumption, and is free from mixing and sedimentation, which comprises a decomposition tank, a discharging pipe which is inserted into the decomposition tank and a discharging chute which is fixed on the wall of the decomposition tank, wherein the decomposition tank (14) is of a flat-bottom straight bucket-shaped structure, an absorption device which is arranged on the bottom part of the decomposition tank is communicated with an entrance of the discharging pipe (6), and a discharging port (4) which is arranged on the discharging pipe (6) is communicated with the discharging chute (5). The sodium aluminate solution column flow flat-bottom decomposer has simple and convenient operation, is free from additional power, has the advantages of no maintenance, low running expense and the like, and is particularly applicable to the modification of the prior mechanical-mixing or air mixing-type flat-bottom straight bucket-shaped decomposer.
Description
Technical field: the utility model relates to a kind of sodium aluminate solution decomposer, relates in particular to the flat decomposer of a kind of sodium aluminate solution.
Background technology: at present, traditional sodium aluminate solution decomposer mainly contains two kinds of cone decomposer and flat straight barrel-shaped decomposers; For fear of precipitation, the cone decomposer adopts pressurized air to stir usually, and flat straight barrel-shaped decomposer then is to adopt mechanism to stir.Pressurized air stirs and not only can cause fine particle agglomeration, the condition of growing up of sodium aluminate solution to be damaged, but also cause the intergranular collision of sodium aluminate solution easily, make xln refinement once more, thereby cause alumina product to be superfine powdery, to be unfavorable for follow-up alumina eltrolysis; In addition, a large amount of pressurized air also can consume a large amount of electric energy.Though mechanism stir help the growing up of nucleus, the alumina product quality is better, has the very expensive defective of equipment, and needs maintaining, and is cumbersome.
In order to overcome the existing defective of above-mentioned taper air agitated precipitator, it is that " 200420034717.X ", name are called the utility model patent of " non-stirring decomposer " that Chinese patent literature discloses application number, its technical scheme is that the bottom of cone decomposer is inserted by the extraction pipe that stock pan is connected with blow tank in a upper end, thereby utilizes the pressure reduction principle that the slurry in the decomposer is extruded.Though this patent has overcome the above-mentioned defective that traditional decomposer exists, but owing to can form a strong vortex at the cone base of decomposer, therefore the top layer slurry can be involved in the bottom, thereby cause the top layer slurry to mix with base pastes, have that part slurry residence time is too short, sodium aluminate solution agglomeration, the condition of growing up be insufficient, decomposes halfway defective.In addition, this patent only is applicable to minor diameter taper air agitated precipitator, can't resolve the existing the problems referred to above of flat straight barrel-shaped decomposer.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide low, simple in structure, the no energy consumption of a kind of cost, does not have stirring, non-setting cylindrical flow flat-bottom decomposing tank of sodium aluminate solution.
To achieve these goals, the utility model is by the following technical solutions: it comprises decomposer, insert discharge nozzle in this decomposer, be fixed on the discharging chute on this decomposition cell wall, decomposer is flat straight barrel shaped structure, the suction device that this decomposer bottom is set is communicated with the inlet of discharge nozzle, and the discharge port that is located on the discharge nozzle is communicated with discharging chute.
Described suction device is made of the aggregate tube that is communicated with the discharge nozzle inlet end, some material sucking pipess, the some arms that gather materials that respectively each material sucking pipes are communicated with aggregate tube of being distributed in decomposer bottom, and material sucking pipes is provided with at least one material sucking port; Material sucking pipes is the straight tube that is arranged in parallel or by the ring pipe of arranged in concentric circles, material sucking port preferably is located at the bottom of material sucking pipes; Be inserted with inlet pipe in the discharge nozzle; Above decomposer, be provided with the charging chute, below this charging chute exit end, be provided with distributor; The arm that respectively gathers materials is communicated with aggregate tube by many aggregate pipes respectively.
Compared with the prior art, the utility model is owing to adopted technique scheme, increased the suction device on the basis of existing technology, therefore can carry out the multiple spot suction in the bottom of slurry, thereby overcome prior art and formed vortex in pulp surface easily, effectively avoided the top layer slurry to be involved in the decomposer bottom, thereby cause top layer slurry and base pastes blended defective, prolonged the residence time of slurry, for the sodium aluminate solution agglomeration, growing up provides sufficient condition, has improved decomposition efficiency; The decomposer that can be suitable for different shape.
