Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, specifically a wastewater filtration device for the production of compound fertilizer from waste salt. Background Technology

[0002] Current compound fertilizers often include humic acid, which can enter the plant through roots, stems, and leaves, reducing the opening of stomata and decreasing water transpiration, thus retaining more moisture in the soil and preventing soil compaction, while also improving soil aeration. However, humic acid is a mixture of natural macromolecular aromatic carboxylic acids, which is generally insoluble in water and difficult for plants to absorb. Even with the addition of humic acid to current compound fertilizers, soil problems cannot be effectively solved or plant growth not significantly promoted. Using waste salts to prepare compound fertilizers can improve the utilization rate of waste salts and ensure the quality of the compound fertilizer. However, the wastewater generated during the production process usually contains a large amount of toxic substances and odors, which can easily pollute the environment and groundwater when discharged. Therefore, we propose a wastewater filtration device for compound fertilizer production using waste salts. This device achieves multi-stage filtration of wastewater through different spaces. During the internal treatment process, the wastewater is stirred and mixed after the addition of a treatment agent, ensuring uniform mixing. In the later stages, the wastewater is further filtered to remove slag and odors, ensuring the cleanliness of the treated water. Utility Model Content

[0023] This technical solution utilizes wastewater filter plates 7, activated carbon plates 10, and antibacterial filter sponges 11. Within the filter box 1, different spaces enable multi-stage filtration of wastewater. Furthermore, during the internal treatment process, the wastewater is stirred and mixed after the addition of treatment agents, ensuring uniform mixing. In the later stages, the wastewater is further filtered to remove sludge and odors, guaranteeing its cleanliness and preventing direct discharge that could pollute the environment and groundwater.

[0024] Example 2:

[0025] Based on Embodiment 1, this utility model is as follows: Figure 3 As shown, a partition plate 3 is vertically installed inside the filter box 1, and the partition plate 3 divides the interior of the filter box 1 into two independent spaces. The right end of the rotating shaft 4 is embedded into the interior of the partition plate 3 and connected by a waterproof bearing. Support seats 9 are fixedly installed on the left side of the partition plate 3 and the upper left side of the inner cavity of the filter box 1. An inclined plate 8 is snapped onto the top of the support seat 9, and the inner end of the inclined plate 8 is connected to the end of the wastewater filter plate 7.

[0026] Adopting such Figure 1 The technical solution shown allows the partition plate 3 to divide the interior of the filter box 1 into two spaces, enabling different levels of filtration of wastewater. An inclined plate 8 is added to the upper end of the wastewater filter plate 7 and integrated with it. This guides the wastewater and allows the inclined plate 8 to be moved out of the interior for cleaning. The concave design of the wastewater filter plate 7 prevents splashing of wastewater, maximizes wastewater capacity, and reduces splashing force during descent.

[0027] Secondly, in the technical solution, a guide plate 12 is fixedly installed at the bottom right side of the inner cavity of the filter box 1. The right end of the guide plate 12 is connected to the inlet of the wastewater discharge pipe 13. In addition, the left end of the guide plate 12 is connected to the right side of the partition plate 3. A treatment pipe 14 is connected to the bottom left side of the front of the filter box 1. A top cover 15 is provided on the upper right side of the inner cavity of the filter box 1.

[0028] Its adoption is as follows Figure 1 The main function of the guide plate 12 in the technical solution shown is to guide the wastewater and prevent internal residue during discharge. In addition, the top cover 15 can be locked above the right side space of the filter box 1 to prevent splashing from the inside during secondary filtration of wastewater.

[0029] Example 3:

[0030] This utility model is as follows Figures 1-4 As shown, a support rod is longitudinally installed on the right side of the inner cavity of the filter box 1, and is installed at equal intervals laterally. The antibacterial filter sponge 11 overlaps the support rod. An installation groove is opened on the right side of the filter box 1 and on the right side of the antibacterial filter sponge 11. A sealing frame is fixedly installed on the outside of the installation groove. The sealing frame can be connected to an external sealing plate.

[0031] The above technical solution is used to add a support rod to the bottom of the antibacterial filter sponge 11 to support its bottom and prevent it from falling when it is impacted by water flow from above. The mounting groove on the right side facilitates the placement and removal of the antibacterial filter sponge 11. At the same time, the external sealing frame can be connected to the sealing plate to seal and shield the outside of the mounting groove to prevent wastewater leakage.

[0032] The working principle of this utility model is as follows: production wastewater is discharged into the interior of filter box 1, where it undergoes simple filtration through wastewater filter plate 7, and is then stored in the left part of the inner cavity of filter box 1. The treatment agent is added inside, and the drive motor 2 is started to drive the rotating shaft 4 and the stirring rod 5 on the surface to mix and stir the wastewater and the treatment agent. Then, it is discharged into the right space through the delivery pump 6. The wastewater passes through activated carbon plate 10 to filter out odors and particulate impurities, and then passes through antibacterial filter sponge 11 to further treat and adsorb fine particles. After treatment and sedimentation for a period of time, it can be discharged from the wastewater discharge pipe 13.
