Description
Technical field
The utility model relates to the saltcake preparing technical field, is specifically related to prepare with the glass gall of salt associated minerals the mother liquor discharger of the terminal evaporating pot in the saltcake.
Background technology
At present, adopt the glass gall of salt associated minerals to produce saltcake, all need pass through the evaporation of multiple-effect evaporation jar, concentrated, crystallization, obtain saltcake through after the liquid-solid separation again.Too high for sodium chloride concentration in the liquid concentrator in the anti-locking system, the general mother liquor that all produces after the liquid concentrator that discharges of evaporating pot, the liquid-solid separation endways effluxes a part (efflux part and go the salt made from earth containing a comparatively high percentage of sodium chloride separation system).Because in order to reduce the temperature and the sodium chloride concentration of the liquid concentrator that terminal evaporating pot discharges; Reach purpose energy-saving and cost-reducing and that improve sodium sulfate I, II class article rate; In process of production; In the nitre pin of evaporating pot, feed the glass gall (terminal evaporating pot nitre pin is provided with former glass gall import) of 40 deg.c continuously, therefore, big from the concentrated liquid measure of nitre pin outflow system, cause the mother liquor amount also big (sodium chloride-containing is 140-180g ∕ L the mother liquor) after liquid-solid separation; Increase the load of salt made from earth containing a comparatively high percentage of sodium chloride separation system, increased the energy consumption of salt made from earth containing a comparatively high percentage of sodium chloride separation system accordingly.
Summary of the invention
The technical problem that the utility model will solve provides a kind of system nitre mother liquor discharger; It is that 140-180g ∕ L liquid concentrator gets into liquid-solid separation system that terminal evaporating pot both can be discharged sodium chloride-containing from the nitre pin, can also be the mother liquor of 250-300g ∕ L from direct discharge sodium chloride-containing in the evaporating pot.
The utility model is realized through following technical scheme:
A kind of system nitre mother liquor discharger (first kind of technical scheme of discharger); The nitre pin that comprises terminal evaporating pot, terminal evaporating pot bottom; Also comprise the liquid concentrator recycle pump and the pipeline thereof that are communicated with terminal evaporating pot; Said terminal evaporating pot roughly axially the middle part be provided with chuck with upper/lower positions, be provided with concentrated solution outlet in the end evaporation tank skin of chuck inner bottom part, or be in the terminal evaporating pot of chuck inner bottom part and break off shape up and down; Said chuck is provided with the mother liquor relief outlet, and said chuck is provided with the mother liquor relief outlet, and said chuck is provided with connected entrance, is communicated with the liquid concentrator feed-pipe of recycle pump.Why endways the roughly axial middle part of evaporating pot is provided with chuck with upper/lower positions, is that the inner top surface of chuck can be lower than the liquid level 1-1.5 rice in the evaporating pot because the height of liquid concentrator is also roughly in this position in the evaporating pot.
The further improvement project of the utility model is that the connected entrance of said mother liquor relief outlet and recycle pump feed-pipe is arranged at chuck top.Said chuck is provided with insulation folder chamber.
A kind of system nitre mother liquor discharger (second kind of technical scheme of discharger); Comprise terminal evaporating pot, pass through the recycle pump that the liquid concentrator feed and exhaust tube is communicated with terminal evaporating pot; The feed-pipe periphery of said recycle pump is provided with chuck; Charging tube wall in the chuck inner bottom part is provided with concentrated solution outlet, or presents down the disconnection shape in the charging tube wall of chuck inner bottom part; Said chuck is provided with the mother liquor relief outlet.
The further improvement project of the utility model is, the connected entrance of recycle pump feed-pipe roughly is arranged at the axial medium position of terminal evaporating pot (its reason such as above-mentioned), and feed-pipe is connected the back and does 90 degree bendings downwards with connected entrance, and chuck is provided with downwards from bending part.Said mother liquor relief outlet is arranged at chuck top.Said chuck is provided with insulation folder chamber.
The utility model compared with prior art has following obvious advantage:
The utility model is owing to evaporating pot periphery or recycle pump feed-pipe periphery are provided with chuck endways; Also since bottom, while that the connected entrance of the connected entrance of evaporating pot and chuck or feed-pipe and chuck is arranged in the chuck mother liquor is set at the chuck top exports; Therefore; The environment that quiescent setting has been arranged behind the liquid entering chuck in the evaporating pot; Sulfate crystal body in first kind of technical scheme directly falls in the nitre pin, and the sulfate crystal body in second kind of technical scheme is along with recycle pump gets in the evaporating pot.The mother liquor that discharges from the chuck top is clear liquor basically, mother liquor sodium chloride-containing 250-300g/L, and from nitre pin mother liquor that discharge, that after liquid-solid separation, obtain, sodium chloride-containing 140-180g/L.Can know from the mother liquor sodium chloride-containing amount of above-mentioned discharge; Under the situation identical at raw material, that turnout is identical; The mother liquor output of the utility model is 1/2nd of a prior art; Alleviate the load of salt made from earth containing a comparatively high percentage of sodium chloride separation system greatly, practiced thrift the energy consumption in equipment investment cost and the system's operational process.
