[0002] Ferrous sulfate is an important chemical raw material with wide applications in various industrial sectors. In wastewater treatment, it serves as a highly efficient flocculant, effectively removing suspended particles, heavy metal ions, and other pollutants from water, thus purifying the wastewater. In agriculture, ferrous sulfate is a common micronutrient fertilizer, supplementing plants with iron, preventing iron deficiency chlorosis, and promoting plant growth and development. In the electroplating industry, ferrous sulfate is a crucial component of the electroplating solution, significantly impacting the electroplating process and quality. However, the production and use of ferrous sulfate inevitably generate large quantities of ferrous sulfate waste liquid, and direct discharge of this waste liquid results in resource waste.

[0003] Traditional methods of treating ferrous sulfate waste liquid result in resource waste, make it inconvenient to recycle and reuse the waste liquid, and make it difficult to filter impurities in the waste liquid during the recycling process, leading to poor subsequent recycling efficiency.

[0004] Therefore, we have made improvements to this and proposed a ferrous sulfate recycling device. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes a ferrous sulfate recycling device, including a curing tank 1. A support plate 2 is fixedly connected to the upper right end of the curing tank 1. A delivery pump 3 is fixedly connected to the upper end of the support plate 2. A suction pipe 4 is fixedly connected to the input end of the delivery pump 3. The bottom end of the suction pipe 4 extends into the interior of the curing tank 1. An inlet pipe 5 is fixedly connected to the output end of the delivery pump 3. A filter cartridge 6 is fixedly connected to the outer end of the inlet pipe 5. A cartridge cover 7 is detachably connected to the upper end of the filter cartridge 6 via a bolt assembly. An installation ring 9 is fixedly connected to the lower end of the cartridge cover 7 via a connecting post 8. A filter screen 10 is fixedly connected inside the installation ring 9. A cleaning mechanism 11 is provided on the lower side of the filter screen 10. An output pipe 12 is fixedly connected to the right side wall of the filter cartridge 6. The top end of the output pipe 12... A return pipe 13 is fixedly connected, and a connecting pipe 14 is fixedly connected to the top end of the return pipe 13. The outer end of the connecting pipe 14 is fixedly connected to the original acid tank 15, and a stirring mechanism 16 is provided inside the original acid tank 15. After the transfer pump 3 is started, the ferrous sulfate waste liquid in the maturation tank 1 is extracted through the extraction pipe 4. After the waste liquid is pressurized by the transfer pump 3, it enters the filter cartridge 6 through the inlet pipe 5. After entering the filter cartridge 6, the waste liquid flows upward under pressure. When it passes through the filter screen 10, the impurities are intercepted by the filter screen 10, thus achieving filtration. The liquid filtered by the filter screen 10 enters the original acid tank 15 through the output pipe 12, the return pipe 13 and the connecting pipe 14, thereby flushing the pipeline and increasing the concentration of ferrous ions in the original acid, realizing the reuse of ferrous sulfate and avoiding waste of resources.

[0018] like Figure 3 As shown, in a preferred embodiment, based on the above method, the cleaning mechanism 11 further includes a support plate 1101 fixed inside the filter cartridge 6. A bearing 1102 is fixedly connected to the center of the lower end face of the support plate 1101. A rotating shaft 1103 is fixedly connected to the inner side wall of the inner ring of the bearing 1102. The top end of the rotating shaft 1103 passes through the support plate 1101 and is fixedly connected to a scraper 1104. The top end of the scraper 1104 contacts the lower end face of the filter screen 10. An impeller 1105 that cooperates with the liquid inlet pipe 5 is fixedly connected to the bottom end of the rotating shaft 1103. When the waste liquid enters the filter cartridge 6 through the liquid inlet pipe 5 and impacts the impeller 1105, the impeller 1105 drives the rotating shaft 1103 to rotate inside the bearing 1102, thereby causing the scraper 1104 to rotate. The scraper 1104 continuously scrapes the lower end face of the filter screen 10 to prevent impurities from clogging the filter screen 10 and ensure the filtration effect.

[0019] like Figure 1 and Figure 4As shown, in a preferred embodiment, based on the above method, the stirring mechanism 16 further includes a motor 1601 fixed at the center of the upper end face of the raw acid tank 15. The driving end of the motor 1601 penetrates the top wall of the raw acid tank 15 and is fixedly connected to a stirring shaft 1602. A set of stirring paddles 1603 are uniformly fixedly connected to the stirring shaft 1602. After the motor 1601 is started, it drives the stirring shaft 1602 and the stirring paddles 1603 to rotate, stirring the liquid in the raw acid tank 15, so that the recycled ferrous sulfate waste liquid and the raw acid are fully mixed evenly.

[0020] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a handle 17 is fixedly connected to the upper end face of the cylinder cover 7, and the corners of the handle 17 are rounded; the handle 17 facilitates the operator to disassemble and install the cylinder cover 7, and to perform operations such as cleaning or replacing the filter screen 10.

[0021] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a solenoid valve 18 is fixedly connected to the bottom output end of the filter cartridge 6, and the bottom of the filter cartridge 6 is a conical design; the solenoid valve 18 can control the discharge of impurities in the filter cartridge 6, and the conical design is conducive to the accumulation of impurities at the bottom, making it easy to discharge.

[0022] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the output pipe 12 is further located on the upper side of the filter screen 10, and the diameter of the mounting ring 9 is the same as the inner diameter of the filter cylinder 6; this facilitates the filtration of impurities in the ferrous sulfate waste liquid and facilitates the installation of the mounting ring 9.

[0023] Specifically, in operation, this ferrous sulfate recycling device works as follows: First, the transfer pump 3 is started. The transfer pump 3 draws out the ferrous sulfate waste liquid from the ripening tank 1 through the extraction pipe 4. After being pressurized by the transfer pump 3, the waste liquid enters the filter cartridge 6 through the inlet pipe 5. After entering the filter cartridge 6, the waste liquid flows upward under pressure. When it passes through the filter screen 10, impurities are intercepted by the filter screen 10, thus achieving filtration. The liquid filtered by the filter screen 10 enters the original acid tank 15 through the output pipe 12, the return pipe 13, and the connecting pipe 14 to increase the concentration of ferrous ions in the original acid. Then, the motor 1601 is started. The motor 1601 drives the stirring shaft 1602 and the stirring paddle 1603 to rotate, stirring the liquid in the original acid tank 15, so that the recycled ferrous sulfate waste liquid and the original acid are fully mixed evenly. When the waste liquid enters the filter cartridge 6 through the inlet pipe 5, it will impact the impeller 1105 to make it rotate. The impeller 1105 drives the rotating shaft 1103 to rotate in the bearing 1102, which in turn makes the scraper 1104 rotate. The scraper 1104 continuously scrapes the lower end face of the filter screen 10 to prevent impurities from clogging the filter screen 10 and ensure the filtration effect.

[0024] All technical features in this embodiment can be freely combined according to actual needs.

[0025] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
