Abstract
Description
Technical Field
[0001] This utility model belongs to the field of potassium nitrate purification technology, specifically relating to a purification device for potassium nitrate processing. Background Technology
[0002] Potassium nitrate (KNO3) is an important inorganic compound, commonly known as saltpeter or earth saltpeter, with the chemical formula KNO3 and a relative molecular mass of 101.10. It usually exists as colorless, transparent orthorhombic crystals, rhombic crystals, or a white powder. It has minimal hygroscopicity in air and does not easily clump. Potassium nitrate has high solubility, with its solubility increasing rapidly with increasing temperature. It is readily soluble in water, liquid ammonia, and glycerol, but insoluble in anhydrous ethanol and ether. As a chlorine-free nitrogen-potassium compound fertilizer, the effective components of potassium nitrate, nitrogen and potassium, can be rapidly absorbed by crops without leaving any chemical residues. Therefore, it is widely used in the fertilization of vegetables, fruits, and flowers, as well as some chlorine-sensitive crops (such as potatoes, strawberries, and beans). Furthermore, potassium nitrate is a strong oxidizing agent and has important applications in industry, food additives, pharmaceuticals, and the electronics industry.
[0003] To meet the purity requirements for potassium nitrate, it is necessary to dissolve, filter, and then condense low-purity granular nitric acid for purification. However, direct dissolution of granular nitric acid results in low dissolution efficiency, affecting the dissolution rate and quality of potassium nitrate, and thus reducing the purification efficiency of potassium nitrate. Therefore, this application proposes a purification device for potassium nitrate processing. Utility Model Content

[0014] Beneficial effects
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention, through the design of a dissolving chamber and a cooling chamber, allows nitric acid to be added into the dissolving chamber. The dissolving solution is then fed into the cooling chamber via a feeding pipe. Combined with electric heating from an electric heating plate, the nitric acid dissolves in the cooling chamber. A reciprocating cylinder transports the dissolved potassium nitrate solution to the cooling chamber via a conveying pipe, where it is filtered through a filter sleeve to remove impurities. A cooling medium is then circulated through the cooling coil to condense the filtered potassium nitrate solution in the cooling chamber. Because the potassium nitrate solution is filtered through the filter sleeve, the purity of the condensed potassium nitrate crystals is increased, thus improving product quality.
[0017] This invention, through the arrangement of a crushing cylinder, a crushing hammer, and a drive mechanism, first feeds the nitric acid to be purified into the crushing cylinder. The drive motor is then activated, causing the guide column and reciprocating cylinder to rotate. The guide column slides along the guide groove on the side wall of the reciprocating cylinder, forcing the reciprocating cylinder to move up and down simultaneously while rotating. This, in turn, drives the shaft to rotate and simultaneously move the crushing hammer up and down. Furthermore, the conical structure at the bottom of the crushing hammer, combined with the bucket-shaped structure at the bottom of the crushing cylinder, effectively crushes and grinds the nitric acid to be purified, significantly improving the dissolution efficiency of potassium nitrate and thus enhancing the purification efficiency of potassium nitrate.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This embodiment provides a purification apparatus for potassium nitrate processing, the schematic diagram of which is shown below. Figures 1-4 As shown, the system includes a cabinet 1, within which a dissolving chamber 8 and a cooling chamber 9 are arranged side-by-side. A water pump 14 is installed in the dissolving chamber 8, and a conveying pipe 15 is connected to the outlet of the water pump 14. The conveying pipe 15 extends into the cooling chamber 9 and is fitted with a filter sleeve 29. A first interlayer 10 is located below the dissolving chamber 8 within the cabinet 1, containing an electric heating plate 11. A second interlayer 12 is located below the cooling chamber 9 within the cabinet 1, containing a cooling coil 13. A third interlayer 16 is located between the dissolving chamber 8 and the cooling chamber 9 within the cabinet 1, filled with heat-insulating cotton to reduce heat conduction. A feeding pipe 18 is installed on the side wall of the cabinet 1, communicating with the interior of the dissolving chamber 8. A cover plate 5 is located on the top of the cabinet 1, corresponding to the position of the cooling chamber 9. Nitric acid is added to the dissolving chamber 8, and the dissolving solution is injected into the cooling chamber 9 through the feeding pipe 18. With the electric heating of the electric heating plate 11, the nitric acid can be dissolved in the cooling chamber 9. The dissolved potassium nitrate solution is transported to the cooling chamber 9 through the conveying pipe 15 by the reciprocating shaft cylinder 24 and filtered through the filter sleeve 29 to remove impurities in the potassium nitrate solution. The cooling medium is circulated into the cooling coil 13 to condense the filtered potassium nitrate solution in the cooling chamber 9. Because the potassium nitrate solution is filtered through the filter sleeve 29, the purity of the potassium nitrate crystals precipitated by condensation is improved, thus improving the quality of the product.
[0026] In a further embodiment, a crushing cylinder 2 is embedded in the top of the cabinet 1 facing the dissolving chamber 8. The bottom of the crushing cylinder 2 has a discharge port 17 extending into the dissolving chamber 8. A crushing hammer 6 is installed inside the crushing cylinder 2. A drive mechanism 4 is installed on the top of the cabinet 1 to drive the crushing hammer 6 to rotate and reciprocate. A support ring seat 7 is provided on the inner side wall of the top of the cabinet 1, and a limiting ring seat 20 is provided on the outer side wall of the crushing cylinder 2, abutting against the support ring seat 7, for supporting and positioning the crushing cylinder 2. The bottom of the crushing cylinder 2 is designed as a bucket shape, and both the top and bottom of the crushing hammer 6 are conical. The nitric acid to be purified is first added into the crushing cylinder 2. The drive mechanism 4 drives the crushing hammer 6 to rotate and reciprocate. Combined with the conical structure at the bottom of the crushing hammer 6 and the bucket shape at the bottom of the crushing cylinder 2, the nitric acid to be purified can be crushed and ground, significantly improving the dissolution efficiency of potassium nitrate and thus increasing the purification efficiency of potassium nitrate.
[0027] In this embodiment, a horizontal plate 3 is fixed to the top of the cabinet 1. The drive mechanism 4 includes a housing 23 fixed to the horizontal plate 3. A column 25 is vertically and rotatably mounted on the inner wall of the housing 23. A reciprocating shaft cylinder 24 is slidably fitted on the column 25. A shaft rod 19 is vertically connected to the bottom end of the reciprocating shaft cylinder 24. The bottom end of the shaft rod 19 extends into the crushing cylinder 2 and is connected to the crushing hammer 6. A drive motor 28 for driving the column 25 to rotate is installed at the top of the housing 23. A guide groove 26 is provided on the side wall of the reciprocating shaft cylinder 24. The guide groove 26 is distributed in an S-shape around the reciprocating shaft cylinder 24. A guide post 27 is fixed on the inner wall of the housing 23. The guide post 27 is embedded in the guide groove 26. The cross-section of the bar post 25 is polygonal, which allows the bar post 25 to drive the reciprocating cylinder 24 to rotate. The drive motor 28 is started to drive the bar post 25 to rotate, and the bar post 25 drives the reciprocating cylinder 24 to rotate. At the same time, the guide post 27 slides along the guide groove 26 on the side wall of the reciprocating cylinder 24, forcing the reciprocating cylinder 24 to reciprocate and rise while rotating. Thus, the shaft rod 19 can drive the breaker hammer 6 to rotate and reciprocate and rise, thereby hammering and grinding the nitric acid in the crushing cylinder 2.
[0028] Furthermore, a lever 21 is radially provided at one end of the shaft 19 that extends into the crushing cylinder 2. The end of the lever 21 is bent downwards, and a support rod 22 is vertically provided on the lever 21. When the shaft 19 rotates and rises, it can drive the lever 21 and the support rod 22 to rotate and rise, thus moving the nitric acid block within the crushing cylinder 2 and preventing the nitric acid from clogging the crushing cylinder 2.
[0029] Working principle: During use, the potassium nitrate to be purified is put into the crushing cylinder 2. The drive motor 28 is started to drive the bar column 25 to rotate, and the bar column 25 drives the reciprocating shaft cylinder 24 to rotate. At the same time, the guide column 27 slides along the guide groove 26 on the side wall of the reciprocating shaft cylinder 24, forcing the reciprocating shaft cylinder 24 to move up and down while rotating. This drives the shaft rod 19 to drive the breaker hammer 6 to rotate and move up and down at the same time. In addition, the conical structure at the bottom of the breaker hammer 6, combined with the bucket-shaped structure at the bottom of the crushing cylinder 2, can hammer-grind and crush the nitrate to be purified. The crushed nitrate falls into the dissolving chamber 8, and then... The feeding pipe 18 injects the dissolving liquid into the cooling chamber 9, and with the electric heating of the electric heating plate 11, the crushed potassium nitrate dissolves in the cooling chamber 9. The reciprocating shaft 24 transports the dissolved potassium nitrate solution to the cooling chamber 9 through the conveying pipe 15 and filters it through the filter sleeve 29 to remove impurities from the potassium nitrate solution. The cooling medium is circulated into the cooling coil 13 to condense the filtered potassium nitrate solution in the cooling chamber 9. Because the potassium nitrate solution is filtered through the filter sleeve 29, the purity of the condensed potassium nitrate crystals is improved, thus improving the quality of the product.
[0030] All technical features in this embodiment can be freely combined according to actual needs.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
