DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] Example

[0024] like Figure 1 、 Figure 2 As shown, a reaction device for agricultural ammonium carbonate deionization includes: a concentrated ammonia pump 100, the suction end of the concentrated ammonia pump 100 is connected to a plate filter 200, and the discharge end of the concentrated ammonia pump 100 is connected to a magnetic filter structure 300; the magnetic filter structure 300 includes a filter shell 310 and a magnetic plate 320, the magnetic plate 320 is inserted into the filter shell 310, and a sealing cover 330 is fixed to the upper end of the filter shell 310, and the upper end of the magnetic plate 320 is fixedly connected to the sealing cover 330.

[0025] like Figure 2 As shown, the magnetic filtration structure 300 is a three-way structure, with the two ends in the horizontal direction being the liquid inlet and the liquid outlet respectively, and an inspection port for inserting the magnetic plate 320 is provided in the vertical direction, and a sealing cover 330 is provided at the upper end of the inspection port;

[0026] The magnetic filtration structure 300 is designed in a three-way configuration to facilitate the inflow and outflow of liquids. Its two horizontal ends are configured as the liquid inlet and outlet, respectively, making the filtration and circulation of liquids more efficient. In the vertical direction, the structure is provided with an inspection port for users to inspect and clean the inserted magnetic plate 320. The sealing cover 330 is tightly set at the upper end of the inspection port, which not only provides a tight seal to ensure safety during the inspection process, but also facilitates users to quickly open and close operations; the overall design takes into account convenience.

[0027] like Figure 2 、 Figure 3 、 Figure 4 As shown, a sealing gasket 311 is provided at the upper end of the inspection port, and the lower surface of the sealing cover 330 is sealed with the sealing gasket 311;

[0028] The access port is tightly fitted with a sealing gasket 311 at its upper end, ensuring airtightness during maintenance. The lower surface of the sealing cover 330 seals against the sealing gasket 311, forming a reliable barrier that effectively prevents the intrusion of external impurities and ensures the cleanliness of the access port. This design not only improves the access port's sealing performance but also enhances the stability of the overall structure, providing a strong guarantee for the safe operation of the equipment.

[0029] like Figure 2 、 Figure 3 、 Figure 4 As shown, a plurality of magnetic plates 320 are provided, and the plurality of magnetic plates 320 are arranged in parallel with equal intervals, and the surface of the magnetic plates 320 is arranged parallel to the flow direction of the liquid in the filter housing 310;

[0030] Multiple magnetic plates 320 are arranged in parallel at equal intervals inside the filter housing 310, and their surfaces are aligned with the flow direction of the liquid in the filter housing 310. In this way, the magnetic plates 320 can effectively absorb and separate magnetic impurities in the liquid, improving filtration efficiency and product quality.

[0031] like Figure 2 、 Figure 3 、 Figure 4 As shown, a buckle 313 is installed on the side wall of the filter housing 310, and a hook 331 is fixed on the side wall of the sealing cover 330, and the buckle 313 is engaged with the hook 331;

[0032] The buckles 313 are symmetrically arranged on both sides of the filter housing 310, and the hooks 331 are arranged in a one-to-one correspondence with the buckles 313;

[0033] The side wall of the filter housing 310 is installed with a clip 313. The design of the clip 313 enables the housing to be firmly connected to the hook 331 fixed on the side wall of the sealing cover 330, so that the sealing cover 330 can be closely aligned with the filter housing 310, realizing quick and convenient disassembly and assembly operations, improving work efficiency and reducing operational difficulty.

[0034] like Figure 2 、 Figure 3 、 Figure 4 As shown, the magnetic plate 320 includes a plug-in shell 321 and a magnetic sheet 322 . The upper end of the plug-in shell 321 is opened, and the magnetic sheet 322 is plugged into the plug-in shell 321 .

[0035] The plug-in housing 321 of the magnetic plate 320 is designed with an open top, which allows the magnetic plate 322 to be easily inserted into the plug-in housing 321. The close fit between the magnetic plate 322 and the plug-in housing 321 ensures that the magnetic plate 320 is not corroded or abraded by liquids, extending the useful life of the magnetic plate 322. Furthermore, after the magnetic plate 320 is inserted into the plug-in housing 321, the outer surface of the plug-in housing 321 has a corresponding magnetic attraction, which can attract the corresponding iron. When cleaning the surface of the plug-in housing 321, the magnetic plate 320 can be removed to demagnetize the surface of the plug-in housing 321, making it easier to clean the surface.

[0036] like Figure 2 、 Figure 3 、 Figure 4 As shown, a cover plate 323 is embedded in the upper end surface of the sealing cover 330 , and the upper ends of the plurality of magnetic pieces 322 are fixedly connected to the cover plate 323 .

[0037] The upper end surface of the sealing cover 330 is cleverly embedded with a cover plate 323, and the upper ends of multiple magnetic pieces 322 are fixedly connected to the cover plate 323. The design of the cover plate 323 facilitates the operation of multiple magnetic pieces 322 at the same time, and also enhances the stability of the magnetic pieces 322, ensuring that they can continue to effectively perform their functions during long-term use.

[0038] like Figure 2 、 Figure 3 、 Figure 4 As shown, a spring piece 324 is fixed on the lower surface of the cover plate 323, a limiting through hole 333 is opened on the surface of the sealing cover 330, and a limiting pin 317 is fixed on the filter housing 310. The spring piece 324 slides through the limiting through hole 333, and the limiting pin 317 conflicts with the spring piece 324.

[0039] The user interface involves first removing the plug-in housing 321 and then removing the magnetic plate 320, allowing any material adsorbed on the surface of the plug-in housing 321 to fall off and facilitate cleaning. To prevent the magnetic plate 320 from separating from the plug-in housing 321 when the plug-in housing 321 is not removed from the filter housing 310, a spring clip 324 is fixed to the lower surface of the cover plate 323. The spring clip 324 is designed to engage with a retaining hole in the sealing cover 330, ensuring a secure lock between the cover plate 323 and the sealing cover 330. The retaining hole 333 forms a sliding fit with the spring clip 324 on the cover plate 323. When the sealing cover 330 is placed on the upper end of the filter housing 310, the retaining pin 317 fixed to the filter housing 310 contacts the spring clip 324, causing it to deform and lock into the retaining hole 333, thereby securing the cover plate 323 and the sealing cover 330. The synergistic action of the spring clip and retaining pin achieves a secure lock, enhancing safety.

[0040] like Figure 2 、 Figure 3 、 Figure 4 As shown, a receiving groove 315 is provided at the upper end of the inspection port of the filter housing 310 , a limiting pin 317 is provided in the receiving groove 315 , and the lower end of the spring piece 324 is correspondingly inserted into the receiving groove 315 , and the inner diameter of the receiving groove 315 is larger than the inner diameter of the limiting through hole 333 .

[0041] The reaction process of agricultural ammonium carbonate deionization:

[0042] Process improvement: Originally, agricultural fertilizers were mainly used to consume ammonia water from triamines, so ammonium carbonate was mainly used to increase production. To increase the production of ammonium carbonate, a large amount of fertilizer additives needed to be added to the system to increase the crystallization speed and particle size of the fertilizer. However, in order to remove metal ions, the addition of additives must be reduced or even eliminated. In order to increase the crystallinity of ammonium carbonate, the only way is to extend the reaction time and crystal growth time. However, the extension of time will increase the outlet exhaust gas. Therefore, the outlet exhaust gas of agricultural fertilizers was changed from entering the triamine to entering the decarbonization inlet, and the original outlet CO2 content of no more than 0.5% was increased to no more than 20%, thereby greatly extending the reaction time in the tower.

[0043] Ammonia filtration: Because the triamine-refined ammonia contains different degrees of melamine and magnetic substances, the original concentrated ammonia pump, ammonia intermediate pump and pipeline are now used to add a magnetic filter and ammonia filter at the outlet of the concentrated ammonia pump and ammonia intermediate pump. The filter is removable and cleanable, which is convenient for daily cleaning.

[0044] Separation control: Control the pushing speed and load of each centrifuge within a reasonable range. The specific implementation is to change the centrifuge main machine ammeter from pointer type to digital type so that the operator can intuitively control the separation load of the centrifuge and thus control the moisture content of the product.

[0045] Product air drying: Since the ammonium carbonate product separated from the centrifuge still contains about 3.5% water, and high moisture content will also affect the instability of the metal ions in the product, a set of hot air drying process is added after the product comes out of the centrifuge to reduce the moisture content of the ammonium carbonate product to below 2.5%.

[0046] With other process operation methods unchanged, the quality of triamine ammonia water has been greatly improved after construction, and the quality of agricultural ammonium carbonate products can also meet the quality requirements of industrial-grade ammonium carbonate; through process improvement, ammonia water filtration, separation control, product air drying and other means, the metal ions in the ammonium carbonate product can be removed.

[0047] The economic benefits generated after actual implementation: industrial fertilizer is 200 yuan higher per ton than agricultural fertilizer. If the annual production of agricultural-grade ammonium urea is 120,000 tons and all of it is calculated as industrial-grade ammonium urea, the annual profit will increase by 24 million yuan.

[0048] Working principle: A magnetic filter structure 300 and a plate filter 200 are added to the outlets of the concentrated ammonia pump 100 and the ammonia water intermediate pump, and a detachable magnetic plate 320 is provided in the magnetic filter structure 300, which is convenient for disassembly and cleaning, and is convenient for daily cleaning. At the same time, the filtered magnetic impurities are collected and recycled, which greatly reduces the content of metal ions in the production process, avoids affecting the manufacturer's use, and increases the added value of the product.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
