Description

Technical Field

[0001] This utility model relates to the technical field of composite water purification agent production equipment, and in particular to a composite polyferric sulfate production equipment. Background Technology

[0002] Composite polyferric sulfate (PFS) is a novel inorganic polymeric flocculant formed by modifying ordinary PFS with one or more modifying components (such as aluminum salts, silicates, high-molecular organic compounds, rare earth elements, etc.). It uses iron ions as its core, forming polynuclear hydroxyl complexes through polymerization. Combined with the synergistic effect of the modifying components, it retains the flocculation ability of traditional PFS while further optimizing water treatment performance. It is a commonly used high-efficiency functional material in the water treatment field. Large-scale production of composite PFS mostly employs the sodium nitrite oxidation method, which generates some impurities during the oxidation process.

[0003] Referring to prior art document 201821348215.2, a composite polyferric sulfate production equipment is provided. By installing a separator in the reaction vessel, which has an inner separator plate and an outer separator plate, the two added reagents can be separately added to the reaction vessel through the inner separator plate or the outer separator plate, so that they are evenly dispersed and the reaction is more complete. The heat preservation box can provide a suitable concentration temperature for the storage box during the concentration stage.

[0004] The device provided in the aforementioned document cannot generate impurities during the oxidation of ferric sulfate. The inability to remove these impurities in a timely manner affects the subsequent stirring process, thereby affecting the purity of the product and reducing its quality. In addition, the stirring of the composite polymerized ferric sulfate by the aforementioned device may be insufficient, affecting the subsequent aging process. The oxidative polymerization reaction is not complete, which affects the production efficiency of the product. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-5 A composite polyferric sulfate production equipment includes a base 1, a fixed platform 2, an aging tank 3, a reaction vessel 4, a stirring motor 6, a stirring rod, and an air compressor 5. A controller that is electrically connected to the stirring motor 6 and the filter motor 17 is fixedly installed on the base 1.

[0026] A fixed frame and a mounting frame are fixedly installed on the aging tank 3. A filter plate 16 is movably installed inside the fixed frame to filter impurities generated during the production of composite polyferric sulfate. The filter plate 16 has a filter hole diameter that is adapted to the particle size of composite polyferric sulfate, accurately intercepting impurities and agglomerated particles generated during the production process.

[0027] The aging tank 3 is equipped with a traction rod 19 for driving the filter plate 16 to swing back and forth via a swing assembly, and a stirring assembly for classifying and stirring the raw materials is provided on the stirring rod.

[0028] The fixed platform 2 and the aging tank 3 are set on the base 1, and the reaction vessel 4 is set on the fixed platform 2.

[0029] The reactor 4 is equipped with a cover plate, which has a feed inlet, an air inlet, an air outlet, and a liquid inlet pipe 7 for feeding the raw materials for preparing composite polymeric ferric sulfate. The reactor 4 is also equipped with a discharge outlet at the bottom.

[0030] The feed inlet is used to feed solid raw materials, such as ferrous sulfate and sulfuric acid. The interface design is compatible with common feeding equipment to prevent raw materials from spilling out during feeding.

[0031] The liquid inlet pipe 7 is specifically used for adding liquid raw materials, such as oxidant solutions and regulator solutions. The liquid raw materials are directly transported into the reactor 4 through the liquid inlet pipe to avoid uneven reaction caused by premature mixing with solid raw materials.

[0032] The bottom of the reactor 4 is equipped with a discharge port, which is located at the lowest point of the reactor, so that the material can be completely discharged after the reaction is completed, thereby improving the utilization rate of raw materials.

[0033] The oscillating assembly includes a filter motor 17 fixedly mounted on a mounting frame. A rotating shaft 24 connected to the output end of the filter motor 17 is movably sleeved inside the mounting frame. Two rotating plates 18 are fixedly mounted at the middle position of the rotating shaft 24. A connecting strip movably sleeved in the traction rod 19 is fixedly mounted between the two rotating plates 18. A vertically arranged fixed rod 20 is fixedly mounted on the fixed frame. A fixed rod 22 is fixedly mounted on the filter plate 16. A movable strip 21 is movably connected between the fixed rod 20 and the fixed rod 22.

[0034] The two ends of the movable bar 21 are connected to the pins of the fixed rod 20 and the fixed rod 22 respectively. A fixed shaft is fixedly installed on the side of the filter plate 16 near the filter motor 17. The traction rod 19 is movably sleeved on the fixed shaft. A baffle for blocking the outward spread of composite polymeric ferric sulfate is fixedly installed on the filter plate 16. A connecting funnel 23 is provided below the filter plate 16. The rotating shaft 24 and the filter plate 16 are set horizontally.

[0035] The design of the oscillating component allows the filter plate 16 to oscillate up and down around the connecting bar, accurately filtering impurities generated during the oxidation process and improving the purity of the composite polyferric sulfate.

[0036] The mixing assembly includes a mounting beam 9 fixedly mounted on the mixing rod, a limiting plate 13, a central mixing paddle 12, and a crushing and mixing head 15 for crushing agglomerated composite polyferric sulfate.

[0037] By designing the agitator 11 as a spiral structure, the raw materials in the upper region of the reactor 4 are spirally sheared and stirred, thereby expanding the flow range of the raw materials in the upper region.

[0038] The central stirring paddle 12 stirs the raw materials in the central area of ​​the reactor 4, and works in conjunction with the end stirring paddle 11 to ensure that the raw materials in the central area are fully mixed and to avoid the formation of dead zones in the stirring.

[0039] The grinding and stirring head 15 grinds the raw materials through its serrated end, eliminating the obstruction of the reaction by agglomeration and increasing the reaction rate of the raw materials.

[0040] The stirring rod is located on the output end of the stirring motor 6. End stirring paddles 11 are fixedly installed on both sides of the mounting beam 9. Two movable plates 14 are connected to the stirring rod by pins to stir the composite polyferric sulfate left and right. The movable plates 14 swing left and right under the action of centrifugal force, further disturbing the raw materials in the reaction vessel 4, enhancing the agitation of the stirring and improving the mixing effect.

[0041] The mounting beam 9 has an U-shaped structure and provides installation space for the alkali bottle 10 and the end stirring paddle 11.

[0042] The end stirring paddle 11 and the middle stirring paddle 12 have a spiral structure, the end of the crushing and stirring head 15 has a serrated structure, the middle stirring paddle 12 is located on both sides of the stirring rod, and the mounting beam 9, the middle stirring paddle 12 and the crushing and stirring head 15 are arranged from top to bottom.

[0043] Through the multi-layered cooperation of the end stirring rod 11, the middle stirring paddle 12, the crushing and stirring head 12 and the moving plate 14, efficient stirring in all dimensions is achieved. The thorough stirring makes the oxidation reaction and polymerization reaction more complete, improves the product cohesion, and increases the yield.

[0044] A drain plate 8 corresponding to the liquid inlet pipe 7 is fixedly installed on the stirring rod. The bottom of the drain plate 8 has evenly spaced through holes. The drain plate 8 has a circular structure and is located above the mounting beam 9. The liquid raw material input by the liquid inlet pipe 7 first flows into the drain plate 8 and is dispersed into fine droplets through the through holes. These droplets are then evenly sprinkled onto the solid raw material in the reactor 4 to avoid local accumulation of liquid raw material and improve the uniformity of liquid-solid mixing.

[0045] Alkali bottles 10 for absorbing nitrogen oxides are fixedly installed at both ends of the mounting beam 9. The nitrogen oxide tail gas generated during the reaction can be introduced into the alkali bottle 10 through the conduit, react with the alkali and be absorbed, reducing the emission of harmful gases and taking into account both production and environmental protection.

[0046] The functional principle of this utility model can be explained through the following operation methods:

[0047] During use, solid or powdered raw materials are manually fed into the feed inlet, and liquid raw materials are injected into the drain pan 8 through the liquid inlet pipe 7.

[0048] The controller sends a start signal to the stirring motor 6. The output end of the stirring motor 6 drives the stirring rod to start rotating. The stirring rod drives the mounting beam 9, the middle stirring paddle 12, and the crushing and stirring head 15 to rotate synchronously. The movable plate 14 rotates while swinging in a V-shape within the limiting plate 13. The end stirring paddle 7 on the mounting beam 9 starts to rotate to stir the material near the inner wall of the reactor 4.

[0049] The resulting composite polyferric sulfate may clump together. This is broken up by stirring with the crushing and stirring head 15 and then leaked into the discharge port.

[0050] The controller sends a start signal to the filter motor 17, the output end of the filter motor 17 drives the rotating shaft 24 to rotate, the rotating shaft 24 drives the rotating plate 18 to rotate synchronously, the rotating plate 18 drives the traction rod 18 to make a compound motion of swinging up and down and rotating around the connecting bar, the traction rod 18 drives the filter plate 16 to move synchronously, and completes the filtration of compound polyferric sulfate impurities.

[0051] During the reaction, harmful gases such as nitrogen oxides may be produced. By energizing the air compressor 5, the compressed air blows the harmful gases to the vicinity of the alkaline solution, where they are absorbed, thus reducing the diffusion of the harmful gases.

[0052] The production of composite polyferric sulfate is complete, all parts are back in place, and the product awaits processing in the next batch.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
