Description
The technical field is as follows:
the utility model belongs to the technical field of inorganic chemical equipment, and mainly relates to a solid-liquid mixing continuous reactor.
Background art:
the superphosphate is an early phosphate fertilizer product produced in China, generally presents as grey or grey-white powder, and the main component of the superphosphate is monocalcium phosphate (Ca (H)2PO4)2·H2O and CaSO4·2H2O) and contains the medium elements such as sulfur, calcium, magnesium and the like required by crops. The superphosphate can be independently used as a phosphate fertilizer to be directly applied, and can also be used as a raw material to be compounded with other fertilizers to produce the compound fertilizer.
At present, the production of superphosphate is mainly carried out by mixing phosphorite with sulfuric acid and reacting by dilute acid ore powder method or concentrated acid slurry method, the reaction process needs three stages of mixing, forming and curing, the cycle time is long, the period lasts for several days or weeks, and the production efficiency is low.
The utility model has the following contents:
in order to overcome the defects, the utility model provides the solid-liquid mixing continuous reactor, which realizes the continuous reaction of sulfuric acid and phosphorite in the production of calcium superphosphate by adopting a solid-liquid mixing-double helix stirring and conveying device without curing, shortens the reaction time and improves the production efficiency.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
the utility model provides a solid-liquid mixing continuous reactor, includes the powder feed bin, and powder feed bin bottom is equipped with feed screw, and feed screw's discharge end passes through the feeding hose to be connected with the mixing chamber, is equipped with liquid inlet pipe and overflow mouth on the mixing chamber, and the overflow mouth is connected with the overflow room, and the overflow room is connected with the reacting chamber, is equipped with double helix stirring conveyor in the reacting chamber, and the end of reacting chamber is equipped with discharge gate and blast pipe, and reaction waste gas gets rid of through the blast pipe at the terminal top of reacting chamber.
The mixing chamber is internally provided with a stirring device, the stirring device comprises an upper stirring blade and a lower stirring blade, and a stirring shaft of the stirring device is connected with a motor at the top of the mixing chamber.
Due to the adoption of the technical scheme, the utility model has the following advantages:
the solid-liquid mixing continuous reactor provided by the utility model can realize the sufficient mixing of the powdered rock phosphate and the concentrated sulfuric acid, accelerate the decomposition capability of the concentrated sulfuric acid on the powdered rock phosphate by double-helix stirring and grinding, improve the effective phosphorus conversion rate, reduce the curing process of the calcium superphosphate and greatly shorten the reaction time.
Description of the drawings:
FIG. 1 is a schematic view of the overall structure of the present invention;
in the figure: 1. a powder bin; 2. a screw feeder; 3. a feed hose; 4. a liquid feed conduit; 5. an overflow port; 6. a mixing chamber; 7. an overflow chamber; 8. a reaction chamber; 9. a double-helix stirring and conveying device; 10. a discharge port; 11. an exhaust pipe; 12. a lower stirring blade; 13. an upper stirring blade; 14. a stirring shaft; 15. an electric motor.
The specific implementation mode is as follows:
the present invention will be explained in more detail by the following examples, which are intended to disclose all changes and modifications within the scope of the present invention, and the present invention is not limited to the following examples;
combine the figure a mixed continuous reactor of solid-liquid, including powder feed bin 1, 1 storehouse bottom of powder material is equipped with feed screw 2, feed screw 2's discharge end passes through feeding hose 3 and is connected with mixing chamber 6, be equipped with liquid inlet pipe 4 and overflow mouth 5 on the mixing chamber 6, liquid inlet pipe 4 is located the top of mixing chamber 6, overflow mouth 5 is located the position that the lateral wall of mixing chamber 6 leaned on, overflow mouth 5 is connected with overflow room 7, overflow room 7 is connected with reacting chamber 8, 8 are equipped with double helix stirring conveyor 9 in the reacting chamber, reacting chamber 8's end is equipped with discharge gate 10 and blast pipe 11, reaction waste gas gets rid of through the blast pipe 11 at 8 terminal tops of reacting chamber.
And a stirring device is arranged in the mixing chamber 6 and comprises an upper stirring blade 13 and a lower stirring blade 12, and a stirring shaft 14 of the stirring device is connected with a motor 15 at the top of the mixing chamber 6.
Solid powder material passes through its bottom opening in powder feed bin 1, enter into screw feeder 2, carry the solid powder material in mixing chamber 6 through screw feeder 2, liquid adds mixing chamber 6 through liquid inlet pipe 4, solid powder and liquid pass through agitating unit stirring mixing at mixing chamber 6 and become even ground paste, then follow overflow mouth 5 along overflow room 7 entering reacting chamber 8, carry the material after the reaction to discharge gate 10 on one side through the stirring of double helix stirring conveyor 9 in reacting chamber 8, the waste gas that the reaction produced passes through the blast pipe 11 discharge at 8 terminal tops of reacting chamber.
The stirring degree and the continuous reaction time can be controlled by adjusting the size, the number and the stirring frequency of the helical blades of the double-helix stirring and conveying device 9 in the reaction chamber 8. When the double-helix stirring and conveying device 9 conveys materials, blades on the helix also perform stirring and grinding cutting, so that solid-liquid full contact is promoted through stirring and grinding cutting, and the reaction rate is accelerated.
