Abstract
The utility model discloses a cooling system structure of a mineral acid pre-mixing tank. The cooling system structure comprises the mineral acid pre-mixing tank (1), wherein an external spraying pipe (2) which can spray the external cylindrical wall of the mineral acid pre-mixing tank (1) is arranged outside the mineral acid pre-mixing tank (1), a cooling water tray (3) is arranged at the outer side of the bottom of the mineral acid pre-mixing tank (1), and a cooling water discharging opening (4) is formed in the bottom of the cooling water tray (3). According to the cooling system structure, the cooling of liquid slurry is carried out in a manner of spraying cooling water to the external wall of equipment, and the cooling water is recovered and recycled by using the tray, so that compared with the existing common methods, the cooling system structure is simple and practical, the equipment is lower in cost and easier to maintain, and an economical and practical cooling manner is realized.
Description
Technical field
The utility model patent relates to a kind of cooling system structure of ore deposit acid pre-mixing groove, belongs to sulfuric acid method titanium pigment production unit technical field.
Background technology
The technological process of Titanium White Production By Sulfuric Acid Process is: the qualified ilmenite concentrate being come by pulverizing process adopts air conveying, sends into the breeze hopper of acidolysis workshop section, and breeze hopper arranges top, storehouse cloth envelop collector.First being 91% with the concentration preparing through the ilmenite concentrate powder of metering, sulfuric acid is mixed into ore pulp in pre-mixing groove, then send into required acid hydrolysis tank through divider, add the spent acid (or little degree water) of a certain amount of concentration as starting acid, by 91% sulfuric acid dilution heat release, slurry temperature is raise, pass into again a small amount of steam and cause acidolysis reaction, main reaction completed in 10 minutes, stirred and helped reaction to carry out simultaneously with pressurized air.After main reaction finishes, in acid hydrolysis tank, add a certain amount of little degree water and process water to leach, then add iron powder that the high price iron in solution is reduced into at a low price iron, after the content of titanous in solution is qualified, go sedimentation operation with pumping.
Due in the ilmenite concentrate of pulverizing after qualified still containing having an appointment 1% moisture, at ore deposit acid pre-mixing groove, after breeze mixes with 91% sulfuric acid, due to the thermopositive reaction of the moisture in breeze and sulfuric acid, the temperature of slurries is raise, very easily cause acidolysis reaction (especially in summer), for avoiding occurring acidolysis reaction, need increase refrigerating unit to ore deposit acid pre-mixing groove.The existing cooling two kinds of modes that are mainly divided into: the one, in equipment, increase spiral coil cooling tube, the 2nd, adopt chuck cooling; Because the ilmenite concentrate granularity after pulverizing is 320 mesh screen residue < 1%, adopt the cooling so thin ilmenite concentrate powder of coil pipe be easy to stick to coil surface and affect cooling performance, if adopt chuck cooling, so large its investment of equipment (device diameters is 4000mm) is larger.
Summary of the invention
The technical problems to be solved in the utility model is, provides that a kind of cost of investment is low, the cooling system structure of a kind of ore deposit acid pre-mixing groove of good cooling results, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: the cooling system structure of ore deposit acid pre-mixing groove, it comprises ore deposit acid pre-mixing groove, be provided with the outer shower that can spray ore deposit acid pre-mixing groove wall of the outer-rotor outward at ore deposit acid pre-mixing groove, bottom land outside at ore deposit acid pre-mixing groove is provided with water coolant pallet, is provided with cooling water outlet in the bottom of water coolant pallet.
The cooling system structure of ore deposit acid pre-mixing groove is, on the wall of the outer-rotor of ore deposit acid pre-mixing groove, is provided with pallet engaging lug, is connected with union lever in the inwall upper end of water coolant pallet, and the other end of union lever is connected with pallet engaging lug.
The cooling system structure of aforementioned ore deposit acid pre-mixing groove is that the other end of union lever and pallet engaging lug are bolted.
Compared with the prior art, the utility model is provided with the outer shower that can spray ore deposit acid pre-mixing groove wall of the outer-rotor outward at ore deposit acid pre-mixing groove, bottom land outside at ore deposit acid pre-mixing groove is provided with water coolant pallet, bottom at water coolant pallet is provided with cooling water outlet, so just can adopt the mode of equipment outer wall spraying cooling water to carry out the cooling of liquid slurry, carry out Recovery and recycle with pallet, relatively existing common method is simple and practical, equipment cost is lower, easy care more, is a kind of economical and practical type of cooling.On the wall of the outer-rotor of ore deposit acid pre-mixing groove, be provided with pallet engaging lug, inwall upper end at water coolant pallet is connected with union lever, the other end of union lever is connected with pallet engaging lug, and this movable connection method can conveniently be safeguarded water coolant pallet, and open design is convenient to circulating water.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment as shown in Figure 1, is provided with the outer shower 2 that can spray ore deposit acid pre-mixing groove 1 wall of the outer-rotor outside ore deposit acid pre-mixing groove 1, outer shower 2 can be connected on the outer wall of ore deposit acid pre-mixing groove 1; Be provided with water coolant pallet 3 in the bottom land outside of ore deposit acid pre-mixing groove 1 simultaneously, be provided with cooling water outlet 4 in the bottom of water coolant pallet 3; Water coolant pallet 3 be fixedly to weld 15 uniform pallet engaging lugs on the wall of the outer-rotor of ore deposit acid pre-mixing groove 1, be welded with union lever 5 in the inwall upper end of water coolant pallet 3, the other end of union lever 5 and pallet engaging lug are bolted.
