Further, described waterworks is by header tank and be with valvular water jet standpipe to form, or by water pump be with valvular water jet standpipe to form, water outlet is provided with shower nozzle, and water spray is vaporific.
Further, described crusher is hammer mill or jaw crusher, is furnished with feeding machine, and the outlet of feeding machine is directly connected with the opening for feed of crusher.
Further, the described unit that once leaches is by leaching container and stirring system forms.
Further, the described filter that once leaches is plate and frame filter, and is furnished with transferpump.
Further, described pulp unit is made up of pulp container and stirring system.
Further, described grinding unit is the ball mill that meets throughput.
Further, described secondary leaches unit by leaching container and stirring system forms.
Further, it is vacuum filter or plate and frame filter that described secondary leaches filter, and is furnished with transferpump.
The supporting pass of the volume of leaching container and pulp container and throughput is: process one ton of arsenic alkali slag, the volume that need to leach container is 3.0～5.0m
3, the volume of pulp container is 1.25～2.5m
3; The discharging-material size of crusher, ball mill can effectively leach the size of separation according to being conducive to arsenic, alkali, antimony, considers the real standard of existing installation simultaneously and breaks the cost grinding and adjust.
Working process of the present utility model is:
Take the arsenic alkali slag of certainweight, open feeding machine to material feeding of crusher, meanwhile, sprayed water to crusher entrance by waterworks, control injection flow rate; Broken material enters and once leaches unit, supplement suitable quantity of water, add oxygenant, leach for the first time, soak after rolling, filter with once leaching filter, obtain a leach liquor and a leached mud, wherein, a leach liquor is mainly containing sodium arseniate, sodium hydroxide, sodium carbonate, one time leached mud is mainly antimony slag, contains a small amount of sodium arseniate, sodium hydroxide and sodium carbonate simultaneously; A leached mud is sent into pulp unit and carry out pulp, when pulp, control amount of water, after pulp is complete, grind; After having ground, material is sent into secondary and is leached unit, amount of makeup water, add oxygenant, leach for the second time, after having leached for the second time, leach filter with secondary and filter, obtain secondary leach liquor and secondary leached mud, wherein, secondary leach liquor, mainly containing sodium arseniate and alkali etc., returns once and leaches in the time that arsenic content is less than 4g/L, as make up water, the antimony slag such as secondary leached mud main component is sodium antimonate.
The secondary leach liquor that leach liquor and arsenic content are greater than 4g/L enters follow-up arsenic alkali separation circuit; Leached mud and secondary leached mud return to antimony regulus system, for reclaiming antimony.
The utility model mainly has the following advantages:
1, waterworks being set sprays water to crusher entrance, adopt wet type fragmentation and wet grinding, airborne dust not in shattering process, has fundamentally solved in arsenic alkali slag dry-type pulverizing, process of lapping and has produced airborne dust, causes secondary environmental pollution, affects the healthy problem of operator;
2 and, due to easily tide of arsenic alkali slag, after the moisture absorption, viscosity is very large, dry-type pulverizing is often carrying out after for some time, can stop up, stuck crusher, and fragmentation cannot smooth and easyly be carried out, the wet type fragmentation that the utility model adopts makes whole shattering process operation smooth and easy;
3, a leaching arsenic alkaline residue after filtering easily agglomerating, become piece, pulp unit is set and carries out pulp, be conducive to be disperseed, fully expose arsenic and alkali in slag, be conducive to arsenic, alkali enters solution;
4, the utility model carries out fragmentation and wet grinding process to arsenic alkali slag, it is exactly leaching process, broken or on one side in mechanical milling process on one side with water, having realized strengthening leaches, mechanical presses after once leaching more easily leaches sodium arseniate wherein, simultaneously, pass through ball milling, obtain the fines that granularity is less than 0.20mm, make arsenic be more prone to leach, improved the leaching efficiency of arsenic, made total arsenic leaching yield > 97.00%, antimony enters slag rate > 95.00%.In the filtrate that processing obtains through the utility model device, the content of arsenic, alkali improves relatively, has accelerated the speed that in subsequent handling, arsenic, alkali separate, and reduces separation costs; And arsenic content in filter residue reduces, the Opening Quantity of arsenic increases, and has reduced time and the cost of arsenic removal in follow-up antimony regulus system, reduces the circulation of arsenic in system.
