The utility model content
The purpose of this utility model provides a kind ofly produces in the feed grade ferrous sulfate monohydrate process and coarse fodder can be separated with fines at the useless secondary iron vitriol of titanium white, with the coarse fodder cycling and reutilization; Avoid can causing production discontinuous by the independent pulverizing of artificial material loading machinery, what produce a large amount of dust polluting environments handles the equipment that utilizes again with iron vitriol.
In order to achieve the above object, the utility model is to adopt following structure:
A kind of equipment that utilizes again that iron vitriol is handled, comprise hotblast stove, pneumatic drier, dry cyclonic separator, finished product cyclonic separator, finished bag filter, cooled exhaust gas blower fan, cooled exhaust gas chimney, dried tail gas blower fan and exhaust scrubber, be connected with impurity removing equipment on the opening for feed of described pneumatic drier, this equipment is made up of beating pump groove, the brilliant groove of commentaries on classics and whizzer, wherein the discharge port of beating pump groove is connected on the opening for feed that changes brilliant groove, and this discharge port that changes brilliant groove is connected on the opening for feed of described pneumatic drier; The air outlet of described hotblast stove links to each other with the blast inlet of described pneumatic drier, the bottom of described pneumatic drier is provided with opening for feed, the discharge port of pneumatic drier upper end links to each other with the opening for feed of described dry cyclonic separator, this drying cyclonic separator also has waste material relief outlet and discharge port, described waste material relief outlet is connected on the described exhaust scrubber by the dried tail gas blower fan, described discharge port is connected to the finished product cyclonic separator by connecting tube, described connecting tube also has blast inlet, described finished product cyclonic separator upper end is the secondary discharge port, the lower end is the finished product discharge port, described secondary discharge port is connected on the described finished bag filter, this finished bag filter has secondary finished product discharge port, is connected with air classifier between described connecting tube and cyclonic separator.
In this device, adopt gas delivery and cooperate air classifier, negative pressure draft by induced draft fan is carried after driving ferrous sulfate monohydrate finished product and air mixed, ferrous efficient panting realization pulverizing certainly in air delivery tube, realize the classification of thickness material again through air classifier, the ferrous sulfate monohydrate finished product that fineness is qualified is packaged as outside the finished product after finished product cyclonic separator and the collection of finished bag filter to be sold.The coarse fodder retrieval system is pulverized again.Realized cooling off with broken and carried out, not only produced and to carry out continuously, also avoided artificial material loading mechanical disintegration to cause the influence of a large amount of dust polluting environments in same gathering system.
In the described exhaust scrubber washing water are housed.
Beneficial effect is: the utility model can separate coarse fodder with fines, with the coarse fodder cycling and reutilization; Avoid to cause production discontinuous, produce a large amount of dust polluting environments, can effectively improve work by the independent pulverizing of artificial material loading machinery.
