Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a hydrophilic magnetic suspension packing material based on composite polymers. Background Technology

[0002] Hydrophilic magnetic suspension packing is a type of suspension packing that introduces magnetic media into a composite polymer matrix and undergoes hydrophilic modification. It combines high specific surface area, good fluidization performance, and controllable weak magnetism, making it suitable for aerobic biochemical scenarios such as MBBR / MBR. It can improve biofilm formation rate and microbial activity, and enhance mass transfer and treatment efficiency.

[0003] Existing magnetic suspension packing materials are prone to shell collapse and deformation under conditions such as water flow impact and acid and alkali corrosion, which reduces the core functions such as biofilm formation efficiency and pollutant adsorption capacity. In addition, the internal magnetic suspension blocks are prone to accumulation, affecting the reaction efficiency. Utility Model Content

The inner side of one end of the outer shell is fixedly connected to the outer side of one end of the inner shell by a mounting ring. The mounting ring closes one end of the annular channel. A second water-permeable hole communicating with the annular cavity is opened on the side wall of the outer shell. A retaining ring is located on the inner side of the outer shell at the end away from the mounting ring, and the other end of the retaining ring that closes the annular channel forms an annular cavity. The retaining ring is detachably connected to the inner shell. The partition is arranged along the axial direction of the outer shell. The two sides of the partition are fixedly connected to the outer shell and the inner shell respectively. Multiple partitions divide the annular cavity into multiple sub-cavities.

[0006] Furthermore, a first water-permeable hole communicating with the annular cavity is opened on the side wall of the inner shell; The mounting ring has a third water-permeable hole that communicates with the annular cavity; The retaining ring has a fourth water-permeable hole that communicates with the annular cavity.

[0007] Furthermore, the diameters of the first, second, third, and fourth water-permeable holes are all 0.5mm-5mm, and they are evenly spaced. Furthermore, a first mounting plate and a second mounting plate are fixedly provided on the inner sidewall of the inner shell along the axis of the inner shell, and the first mounting plate and the second mounting plate are perpendicular to each other.

[0008] Furthermore, a connecting ring is fixedly provided at one end of the retaining ring away from the annular cavity. A connecting block is fixedly provided on the inner side of the connecting ring. An installation block is fixedly provided on the connecting block. A U-shaped plate is fixedly provided on the installation block. The opening of the U-shaped plate corresponds to the second installation plate. The second installation plate is located between the two vertical plates of the U-shaped plate. An installation groove is opened on the end face of the vertical plate of the U-shaped plate near the second installation plate. A rubber block is provided in the installation groove. The rubber block protrudes from the end face of the vertical plate near the second installation plate. A positioning groove matching the rubber block is opened on the second installation plate.

[0009] Furthermore, the end face of the rubber block adjacent to the second mounting plate is an arc-shaped surface.

[0010] Furthermore, the connection position between the first mounting plate and the second mounting plate coincides with the axial direction of the inner shell, and the portion of the first mounting plate near the axial direction of the inner shell is fixedly connected to the portion of the second mounting plate near the axial direction of the inner shell through reinforcing ribs.

[0011] Furthermore, the partition is fixedly connected to the outer wall of the inner shell by reinforcing ribs.

[0012] Furthermore, the multiple partitions are axially and uniformly arranged along the axis of the inner shell, and the multiple partitions divide the annular cavity into multiple sub-cavities of the same volume.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 7 As shown, a hydrophilic magnetic suspension filler based on composite polymer includes: an outer shell 1, an inner shell 2 provided inside the outer shell 1, forming an annular channel between the outer shell 1 and the inner shell 2, the inner side of one end of the outer shell 1 being fixedly connected to the outer side of one end of the inner shell 2 by a mounting ring 16, the mounting ring 16 closing one end of the annular channel, and a second water-permeable hole 8 communicating with the annular cavity on the side wall of the outer shell 1; a retaining ring 9, the retaining ring 9 being located on the inner side of the end of the outer shell 1 away from the mounting ring 16, the retaining ring 9 closing the other end of the annular channel to form an annular cavity, the retaining ring 9 being detachably connected to the inner shell 2; and partitions 3, the partitions 3 being arranged along the axial direction of the outer shell 1, the two sides of the partitions 3 being fixedly connected to the outer shell 1 and the inner shell 2 respectively, the multiple partitions 3 dividing the annular cavity into multiple sub-cavities, and at least one sub-cavity containing a magnetic suspension block 15.

[0022] The arrangement of multiple sub-cavities prevents the magnetic suspension blocks 15 in different sub-cavities from interfering with each other, ensuring uniform concentration of magnetic suspension blocks 15 in each unit and improving reaction efficiency. The channels in the unfilled sub-cavities and inner shell 2 provide water flow channels, avoiding the obstruction of impurity diffusion caused by excessive density of magnetic suspension blocks 15. The channels in the unfilled sub-cavities and inner shell 2 can carry away detached biofilm and suspended particles, reducing the risk of accumulation and blockage in the outer shell 1 and inner shell 2.

[0023] The inner shell 2 has a first water-permeable hole 7 communicating with the annular cavity on its side wall; the mounting ring 16 has a third water-permeable hole 17 communicating with the annular cavity; and the retaining ring 9 has a fourth water-permeable hole 19 communicating with the annular cavity. The arrangement of the first water-permeable hole 7, the second water-permeable hole 8, the third water-permeable hole 17, and the fourth water-permeable hole 19 facilitates the entry of sewage into the sub-cavity and its contact with the magnetic suspension block 15, thereby improving the sewage treatment efficiency.

[0024] The diameters of the first permeable hole 7, the second permeable hole 8, the third permeable hole 17, and the fourth permeable hole 19 are all 0.5mm-5mm and are evenly spaced. In this embodiment, the diameter is 2mm, which provides sufficient space for the colonization of microorganisms such as bacteria and fungi, while avoiding the situation where the biofilm is not firmly attached due to excessively large pore size, or internal blockage and inability of microorganisms to penetrate due to excessively small pore size.

[0025] A first mounting plate 6 and a second mounting plate 4 are fixed on the inner sidewall of the inner shell 2 and are arranged along the axis of the inner shell 2. The first mounting plate 6 and the second mounting plate 4 are arranged perpendicularly to each other. The first mounting plate 6 and the second mounting plate 4 play the role of supporting the inner sidewall of the inner shell 2 and improving the structural strength of the inner shell 2.

[0026] In some embodiments, such as Figure 6 As shown, a connecting ring 10 is fixedly mounted on the end of the retaining ring 9 away from the annular cavity. A connecting block 11 is fixedly mounted on the inner side of the connecting ring 10. An mounting block 12 is fixedly mounted on the connecting block 11. A U-shaped plate 13 is fixedly mounted on the mounting block 12. The opening of the U-shaped plate 13 corresponds to the second mounting plate 4. The second mounting plate 4 is located between the two vertical plates of the U-shaped plate 13. An installation groove is opened on the end face of the vertical plate of the U-shaped plate 13 near the second mounting plate 4. A rubber block 14 is provided in the installation groove. The rubber block 14 is fixedly connected to the bottom end of the installation groove. The rubber block 14 protrudes from the end face of the vertical plate near the second mounting plate 4. A positioning groove 5 matching the rubber block 14 is opened on the second mounting plate 4. The part of the rubber block 14 protruding from the vertical plate near the second mounting plate 4 is located inside the positioning groove 5. The end face of the rubber block 14 near the second mounting plate 4 is an arc-shaped surface (e.g., Figure 7 As shown in the figure, the arc-shaped surface plays a guiding role during the deformation of the rubber block 14, making the installation process of the connecting ring 10 more convenient.

[0027] When installing the retaining ring 9, the U-shaped plate 13 is aligned with the second mounting plate 4 and inserted. During this process, the rubber block 14 is deformed and compressed. When the rubber block 14 is aligned with the positioning groove 5, the rubber block 14 is reset and inserted into the positioning groove 5 under the action of elasticity to complete the limiting of the connecting ring 10. The operation is convenient and it is easy to disassemble the retaining ring 9 to replace and maintain the magnetic suspension block 15.

[0028] In other embodiments, a connecting ring 10 is fixedly provided at one end of the retaining ring 9 away from the annular cavity. A connecting block 11 is fixedly provided on the inner side of the connecting ring 10. An mounting block 12 is fixedly provided on the connecting block 11. A U-shaped plate 13 is fixedly provided on the mounting block 12. The opening of the U-shaped plate 13 corresponds to the second mounting plate 4. The second mounting plate 4 is located between the two vertical plates of the U-shaped plate 13. A threaded hole corresponding to the vertical plate of the U-shaped plate 13 is opened on the second mounting plate 4. A through hole corresponding to the threaded hole is opened on the vertical plate of the U-shaped plate 13. A connecting bolt is provided in the through hole. The connecting bolt is threaded to the inner side of the threaded hole through the through hole.

[0029] The connection position of the first mounting plate 6 and the second mounting plate 4 coincides with the axial direction of the inner shell 2. The portion of the first mounting plate 6 near the axial direction of the inner shell 2 is fixedly connected to the portion of the second mounting plate 4 near the axial direction of the inner shell 2 by a reinforcing rib 18. The reinforcing rib 18 improves the structural strength of the connection between the first mounting plate 6 and the second mounting plate 4.

[0030] The partition 3 is fixedly connected to the outer wall of the inner shell 2 by a reinforcing rib 18, which improves the structural strength between the partition 3 and the inner shell 2.

[0031] In some embodiments, all sub-cavities are provided with magnetic levitation blocks 15, or a specified number of sub-cavities are filled with magnetic levitation blocks 15 as needed.

[0032] In other embodiments, multiple partitions 3 are axially and uniformly arranged along the axis of the inner shell 2, and the multiple partitions 3 divide the annular cavity into multiple sub-cavities of the same volume. The partitions 3 have a fifth water-permeable hole. The multiple inner sub-cavities are equipped with magnetic suspension blocks 15. The sub-cavities equipped with magnetic suspension blocks 15 and the empty sub-cavities are arranged alternately. Through the spacing of the magnetic suspension blocks 15, water can also flow through the partitions 3, which increases the flow of gas in the magnetic suspension blocks 15 and improves the performance.

[0033] The outer shell 1, inner shell 2, partition 3, mounting ring 16, and retaining ring 9 are structural components made of epoxy resin, which has good corrosion resistance and extends service life.

[0034] Work process: In implementing this scheme, the magnetic suspension block 15 is hydrophilically modified, and then the magnetic suspension block 15 is placed into the sub-cavity. The retaining ring 9 is connected to the inner shell 2. Then, the hydrophilic magnetic suspension filler can be placed into the water that needs to be treated. The hydrophilicity of the magnetic suspension block 15 makes it easier to wet, increasing the solid-liquid contact area. At the same time, it promotes the adsorption, attachment and subsequent biodegradation of pollutants in the water on the surface of the magnetic suspension block 15, allowing the pollutants in the water to enter the magnetic suspension block 15 in the sub-cavity.

[0035] The partition 3 not only separates the annular cavity, but also increases the structural strength between the outer shell 1 and the inner shell 2, and increases the compressive and impact resistance of the hydrophilic magnetic suspension filler.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
