Description

Technical Field

[0001] The utility model relates to the field of producing ammonium phosphate with low-grade raffinate acid, and particularly relates to a device for producing ammonium phosphate by using low-grade raffinate acid. Background Art

[0002] Raffinate acid is a by-product generated when preparing phosphoric acid by the reaction of phosphoric acid monoester and sodium hydroxide. Ammonium phosphate is a colorless and transparent crystal, which is formed by the reaction of ammonia and phosphoric acid and is widely used in fields such as chemical fertilizers, water treatment, and food. Mixing raffinate acid and ammonia water, carrying out a dehydration reaction in a reaction kettle, and then cooperating with subsequent steps such as evaporation and crystallization can produce monoammonium phosphate.

[0003] Generally, scale will adhere to the inner wall of the reaction kettle during the reaction in the reaction kettle. These scales are inside the reaction kettle, so it is not easy for workers to directly clean them. Long-term adhesion will make it more difficult to clean, which will further affect the subsequent normal operation of the reaction kettle, such as polluting the normal chemical reaction process. Summary of the Utility Model

[0004] Based on the above description, the utility model provides a device for producing ammonium phosphate by using low-grade raffinate acid to solve the problem that scale is generated on the inner wall of the existing reaction kettle, making it difficult to clean.

[0027] Please refer to Figure 1 and Figure 2 , a device for producing ammonium phosphate using low-grade raffinate acid, including a device main body 1. A support frame 3 is provided at the bottom of the device main body 1, and a feed inlet and a discharge outlet are respectively provided at the top and the bottom of the device main body 1;

[0028] An active part 2 is provided at the top of the device main body 1. The active part 2 includes a stirring assembly 201, a transmission assembly 202, a scraper 203, and a connection assembly 204. The transmission assembly 202 is arranged inside the stirring assembly 201, the scraper 203 is arranged on the side wall of the transmission assembly 202, and the connection assembly 204 is used to connect the stirring assembly 201 and the scraping assembly.

[0029] A scraper 203 is added to the active part 2, so that the scraper 203 rotates with the stirring assembly 201 in cooperation with the connection assembly 204 and the transmission assembly 202, so that the scraper 203 can scrape and clean the inner wall of the device main body 1 to remove the impurities adsorbed on the inner wall of the device main body 1.

[0030] Please refer to Figure 1 and Figure 2 , the stirring assembly 201 of this embodiment is composed of a main rod 2011, a first gear 2012, a second gear 2013, a motor 2014, and a stirring rod 2015. The motor 2014 is installed at the top of the device main body 1, the main rod 2011 is fixedly installed on the output end of the motor 2014, and the first gear 2012 is installed on the surface of the main rod 2011.

[0031] Please refer to Figure 1 and Figure 2 , the top of the main rod 2011 of this embodiment is connected to the device main body 1 through a bearing, and the second gear 2013 is fixedly installed on the main rod 2011, and the second gear 2013 meshes with the first gear 2012. The stirring rod 2015 is fixedly installed on the side wall of the main rod 2011, and an installation groove is provided inside the main rod 2011.

[0032] Starting the motor 2014 allows the motor 2014 to drive the first gear 2012 to rotate. The first gear 2012 will then drive the second gear 2013 to rotate. Since the second gear 2013 is fixed to the main rod 2011, the main rod 2011 rotates, and together with the stirring rod 2015 on the main rod 2011, it performs a stirring operation inside the device main body 1.

[0033] Please refer to Figure 2 and Figure 3 , the transmission component 202 of this embodiment consists of a central rod 2021 and a convex rod 2022. The convex rod 2022 is fixedly installed on the end face of the central rod 2021, and the central rod 2021 is movably inserted into the installation groove inside the main rod 2011.

[0034] Please refer to Figure 2 and Figure 3 , one side of the scraper 203 of this embodiment is provided with a rectangular groove. The convex rod 2022 is movably inserted into the inner cavity of the rectangular groove of the scraper 203, and the side wall of the scraper 203 is movably attached to the inner wall of the device main body 1.

[0035] The cross-section of the convex rod 2022 is rectangular. Inserting the convex rod 2022 into the inner cavity of the rectangular groove facilitates the central rod 2021 to drive the scraper 203 to rotate.

[0036] Please refer to Figure 2 and Figure 3 , the connection component 204 of this embodiment includes a connecting plate 2041, a vertical plate 2042, and a sleeve 2043. The vertical plate 2042 is fixedly installed at the bottom of the connecting plate 2041, and the sleeve 2043 is fixedly installed on the surface of the main rod 2011.

A plurality of threaded grooves are evenly opened on the side wall of the sleeve 2043. A screw is threadedly connected to the inner cavity of the threaded groove on the side close to the vertical plate 2042, and the end of the screw away from the threaded groove threadedly penetrates through the vertical plate 2042.

[0038] Let the threaded rod pass through the vertical plate 2042 and enter the threaded groove of the sleeve 2043 to fix the central rod 2021 to the main rod 2011. At this time, when the main rod 2011 rotates, it will drive the central rod 2021 to rotate together. Since the central rod 2021 is inserted into the rectangular groove of the scraper 203 and the convex rod 2022 is in contact with the rectangular groove, it drives the scraper 203 to rotate, so that the scraper 203 scrapes and cleans the inner wall of the device main body 1.

[0039] An additional connecting component 204 is provided. By loosening the threaded rod, the central rod 2021 is separated from the main rod 2011, so that the scraper 203 will not rotate, and the working state can be switched, preventing the scraper 203 from continuously scraping the inner wall of the device main body 1 and causing wear.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
