Description

Technical Field

[0001] This utility model belongs to the field of microbial culture packing ball design technology, specifically a microbial culture packing ball for sewage treatment with improved structure. Background Technology

[0002] Wastewater treatment microbial packing balls are usually used in conjunction with biological suspended ball packing. The surface and internal pores of the packing balls provide a large number of attachment sites for microorganisms. Microorganisms in wastewater gradually gather, grow and reproduce on the surface of the packing, forming a biofilm. The microorganisms in the biofilm can decompose pollutants into harmless substances such as carbon dioxide, water and nitrogen, thereby purifying the wastewater.

[0003] The existing bacterial culture packing balls used for sewage treatment have a relatively simple structure, usually consisting of individual, openable spheres. However, in daily use, staff typically put multiple packing balls into the sewage at once. When the packing balls need to be retrieved for reuse, staff have to retrieve them one by one, which is quite inconvenient.

[0004] Therefore, this utility model provides a structurally improved microbial packing ball for sewage treatment. Utility Model Content

[0007] Preferably, sealing sheets are provided on the sidewalls of the first and second packing hemispheres; fixing protrusions are fixedly connected to the sidewalls of the sealing sheets, and multiple fixing protrusions are arranged correspondingly; a locking block is fixedly connected to the sidewall of the fixing protrusion; a locking platform is fixedly connected to the sidewalls of the first and second packing hemispheres, and multiple locking platforms are arranged corresponding to the positions of the locking blocks; a locking groove is opened on the sidewall of the locking platform, and multiple locking grooves are respectively arranged corresponding to the size of the locking blocks; through the above structure, the locking blocks and locking grooves fix the sealing sheets to the sidewalls of the first and second packing hemispheres, thereby sealing the first and second packing hemispheres, preventing the packing material from falling out, and making the sealing sheets detachable, which is conducive to the repeated use of the bacterial packing balls for sewage treatment and helps to reduce sewage treatment costs.

[0008] Preferably, a sealing frame is rotatably connected to the side wall of the packing cylinder; a sealing strip is fixedly connected to the side wall of the sealing frame, and multiple sealing strips are arranged correspondingly; fixing holes are opened on the side wall of the sealing frame and the packing cylinder, and two fixing holes are arranged correspondingly; through the above structure, the rotatable sealing frame and sealing strip block the filling material inside the packing cylinder, preventing the filling material from falling out, while providing convenience for the staff to add filling material. The setting of the fixing platform for the sealing frame is beneficial to improving the stability of the microbial packing ball.

[0009] Preferably, a fixing block is fixedly connected to the side wall of the first packing hemisphere and the second packing hemisphere; a rotating block is rotatably connected to the side wall of the fixing block, and the rotating block is fixedly connected to the side wall of the sealing sheet; through the above structure, the fixing block and the rotating block connect the first packing hemisphere and the sealing sheet, and connect the second packing hemisphere and the sealing sheet. By means of the rotational connection between the components, the components are connected as one, which helps to prevent the sealing sheet from detaching when the locking block and the locking groove lose contact.

[0010] Preferably, the bottom of the packing cylinder is fixedly connected to a foot support block, and the two foot support blocks are arranged in a corresponding manner. Through the above structure, the foot support blocks enable the first packing hemisphere, the packing cylinder and the second packing hemisphere connected to each other to maintain a stable state during the packing material addition stage, which helps to reduce the difficulty of adding the packing material of the microbial packing balls and improve the addition efficiency.

[0011] Preferably, the sealing sheet has a groove on its side wall, the packing cylinder has a groove on its side wall, and multiple grooves are arranged in a circumferential array. With the above structure, the grooves on the side walls of the packing cylinder and the sealing sheet increase the flowability of the packing balls and reduce the difficulty of sewage entering the packing balls.

[0024] like Figures 1 to 4 As shown in the figure, an improved wastewater treatment microbial packing ball according to an embodiment of the present invention includes a first packing hemisphere 1, a packing cylinder 11, and a second packing hemisphere 12. A connecting valve 13 is provided on the side wall of the first packing hemisphere 1; a connecting block 14 is provided on the side wall of the second packing hemisphere 12, and the connecting valve 13 and the connecting block 14 are correspondingly arranged; a connecting valve 13 and a connecting block 14 are provided on the corresponding side wall of the packing cylinder 11; a rod 15 is slidably connected inside the connecting valve 13; a limit ring is fixedly connected to the side wall of the rod 15. 16, and a return spring 17 is fixedly connected between the limiting ring 16 and the connecting valve 13; the insert rod 15 penetrates the side wall of the connecting valve 13, and a pull ring 18 is fixedly connected to one end of the insert rod 15; during operation, the connecting valve 13 is provided on the side wall of the first packing hemisphere 1, the connecting block 14 is provided on the side wall of the second packing hemisphere 12, and the connecting valve 13 and the connecting block 14 are provided on the side wall of the packing cylinder 11. The operator can connect the first packing hemisphere 1, the packing cylinder 11 and the second packing hemisphere 12 with the connecting block 14 and the connecting valve 13 by means of the connecting assembly. The material hemisphere 12, or connecting the first packing hemisphere 1 and the second packing hemisphere 12, is used by the operator to pull the insertion rod 15 with the pull ring 18. The return spring 17, fixed between the connecting valve 13 and the limiting ring 16, will contract. At this time, the operator can insert the connecting block 14 into the connecting valve 13. After the connecting block 14 is inserted into the connecting valve 13, the pull ring 18 is released, allowing the insertion rod 15 to naturally return to its original position under the elastic force of the return spring 17. After the insertion rod 15 returns to its original position, the connecting block 14 will be placed inside the limiting connecting valve 13. In this configuration, adjacent first packing hemisphere 1, packing cylinder 11, and second packing hemisphere 12 are interconnected. This structure, which includes the first packing hemisphere 1, packing cylinder 11, and second packing hemisphere 12 to accommodate microbial packing, and a connecting block 14 connecting to the connecting valve 13 and its connecting assembly, enhances the structural flexibility of the microbial packing balls used in wastewater treatment, improves their applicability, and expands their application range.

[0025] like Figure 1 , Figure 2 and Figure 4As shown, sealing plates 2 are provided on the sidewalls of the first packing hemisphere 1 and the second packing hemisphere 12; fixing protrusions 21 are fixedly connected to the sidewalls of the sealing plates 2, and multiple fixing protrusions 21 are arranged correspondingly; locking blocks 22 are fixedly connected to the sidewalls of the fixing protrusions 21; locking platforms 23 are fixedly connected to the sidewalls of the first packing hemisphere 1 and the second packing hemisphere 12, and multiple locking platforms 23 are arranged corresponding to the positions of the locking blocks 22; locking grooves 24 are opened on the sidewalls of the locking platforms 23, and multiple locking grooves 24 are respectively arranged corresponding to the size of the locking blocks 22; during operation, sealing plates 2 are provided on the sidewalls of the first packing hemisphere 1 and the second packing hemisphere 12. Since locking blocks 22 are fixedly connected to the sidewalls of the multiple fixing protrusions 21 fixed to the sealing plates 2, and locking grooves 24 are opened on the surface of the locking platforms 23 fixed to the sidewalls of the first packing hemisphere 1 and the second packing hemisphere 12, the operator can... Multiple locking blocks 22 are respectively inserted into the locking grooves 24 to fix the sealing sheet 2 on the side walls of the first packing hemisphere 1 and the second packing hemisphere 12, thereby confining the packing material between the first packing hemisphere 1 and the sealing sheet 2, and between the second packing hemisphere 12 and the sealing sheet 2, preventing the packing material from falling out. At the same time, the operator can open the sealing sheet 2 during the packing material addition stage, and after the addition is completed, the sealing sheet 2 can be fixed back on the side walls of the first packing hemisphere 1 and the second packing hemisphere 12. Through the above structure, the locking blocks 22 and the locking grooves 24 fix the sealing sheet 2 on the side walls of the first packing hemisphere 1 and the second packing hemisphere 12, thereby sealing the first packing hemisphere 1 and the second packing hemisphere 12 and preventing the packing material from falling out. At the same time, the sealing sheet 2 is detachable, which is conducive to the repeated use of the bacterial packing balls for sewage treatment and helps to reduce sewage treatment costs.

[0026] like Figure 1 and Figure 3 As shown, a sealing frame 3 is rotatably connected to the side wall of the packing cylinder 11; a sealing strip 31 is fixedly connected to the side wall of the sealing frame 3, and multiple sealing strips 31 are arranged correspondingly; fixing holes 32 are opened on the side wall of the sealing frame 3 and the packing cylinder 11, and two fixing holes 32 are arranged correspondingly; during operation, the sealing frame 3 is rotatably connected to the side wall of the packing cylinder 11, and the operator can more conveniently add filler into the inside of the packing cylinder 11 by rotating the sealing frame 3. At the same time, whenever the filler is added, the operator can rotate the sealing frame 3 to the side wall of the packing cylinder 11 and fix the sealing frame 3 to the side wall of the packing cylinder 11 through the fixing holes 32. Among them, multiple sealing strips 31 play the role of blocking the filler and preventing the filler from falling out. Through the above structure, the rotatable sealing frame 3 and sealing strips 31 are set to block the filler inside the packing cylinder 11 and prevent the filler from falling out, while providing convenience for the operator to add filler. The setting of the clamping platform 23 to fix the sealing frame 3 is beneficial to improving the stability of the microbial packing ball.

[0027] like Figure 2 and Figure 4As shown, a fixing block 4 is fixedly connected to the side wall of the first packing hemisphere 1 and the second packing hemisphere 12; a rotating block 41 is rotatably connected to the side wall of the fixing block 4, and the rotating block 41 is fixedly connected to the side wall of the sealing sheet 2; during operation, since the rotating block 41 fixed to the side wall of the sealing sheet 2 is rotatably connected to the fixing block 4 fixed to the side wall of the first packing hemisphere 1 and the packing cylinder 11, the first packing hemisphere 1 and the sealing sheet 2, and the second packing hemisphere 12 and the sealing sheet 2 will simultaneously have a rotatable connection; through the above structure, the fixing block 4 and the rotating block 41 are set to connect the first packing hemisphere 1 and the sealing sheet 2, and to connect the second packing hemisphere 12 and the sealing sheet 2. By means of the rotatable connection between the components, the components are connected as one, which helps to prevent the sealing sheet 2 from detaching when the locking block 22 and the locking groove 24 lose contact.

[0028] like Figure 1 and Figure 3 As shown, a foot support block 5 is fixedly connected to the bottom of the packing cylinder 11, and the two foot support blocks 5 are arranged correspondingly. During operation, the foot support block 5 is fixedly connected to the bottom of the packing cylinder 11, and the operator can use the two foot support blocks 5 to place the packing cylinder 11 on the workbench, thereby preventing the packing cylinder 11 and the first packing hemisphere 1 and the second packing hemisphere 12 connected to the packing cylinder 11 from rolling during the filling stage. Through the above structure, the foot support block 5 enables the first packing hemisphere 1, the packing cylinder 11 and the second packing hemisphere 12 connected to each other to maintain a stable state during the filling stage, which helps to reduce the difficulty of filling the microbial packing balls and improve the filling efficiency.

[0029] like Figure 2 and Figure 3 As shown, a groove 6 is provided on the side wall of the sealing plate 2 and a groove 6 is provided on the side wall of the packing cylinder 11, and multiple grooves 6 are arranged in a circumferential array. During operation, the grooves 6 on the side wall of the sealing plate 2 and the grooves 6 on the side wall of the packing cylinder 11 can reduce the surface area of ​​the packing cylinder 11 and the sealing plate 2, thereby increasing the area where sewage can enter the packing ball. Through the above structure, the grooves 6 on the side walls of the packing cylinder 11 and the sealing plate 2 increase the flowability of the packing ball and reduce the difficulty of sewage entering the packing ball.

[0030] like Figure 4 As shown, the insertion rod 15, limiting ring 16, return spring 17, and pull ring 18 are made of stainless steel. During operation, the use of stainless steel in the insertion rod 15, limiting ring 16, return spring 17, and pull ring 18 allows the high structural strength and strong corrosion resistance of stainless steel to be fully utilized. Through the above, the use of stainless steel in the insertion rod 15, limiting ring 16, return spring 17, and pull ring 18 enhances their structural strength, reduces their corrosion risk, and helps to improve the reusability of the microbial filler balls.

[0031] During operation, a connecting valve 13 is installed on the side wall of the first packing hemisphere 1, a connecting block 14 is installed on the side wall of the second packing hemisphere 12, and a connecting valve 13 and a connecting block 14 are installed on the side wall of the packing cylinder 11. Operators can connect the first packing hemisphere 1, the packing cylinder 11, and the second packing hemisphere 12, or connect the first packing hemisphere 1 and the second packing hemisphere 12, using the connecting block 14 and the connecting valve 13 as connecting components. During this process, operators can pull the insertion rod 15 using the pull ring 18. The return spring 17, fixed between the connecting valve 13 and the limit ring 16, will contract. At this time, the operator can insert the connecting block 14 into the connecting valve 13, and after the connecting block 14 is inserted into the connecting valve 13, release the pull ring 18, allowing the insertion rod 15 to retract within the return spring. Under the elastic force of 17, the plug rod 15 resets naturally. After the plug rod 15 resets, the connecting block 14 will be limited inside the connecting valve 13. The adjacent first packing hemisphere 1, packing cylinder 11, and second packing hemisphere 12 will be connected to each other. Sealing plates 2 are respectively provided on the side walls of the first packing hemisphere 1 and the second packing hemisphere 12. Since multiple fixing protrusions 21 fixed to the sealing plate 2 have locking blocks 22 fixed to their side walls, and the surface of the locking platform 23 fixed to the side walls of the first packing hemisphere 1 and the second packing hemisphere 12 has a locking groove 24, the operator can fix the sealing plate 2 to the side walls of the first packing hemisphere 1 and the second packing hemisphere 12 by inserting multiple locking blocks 22 into the locking groove 24, thereby restricting the filling material between the first packing hemisphere 1 and the sealing plate 2. Between the two sealing strips 2, the second packing hemisphere 12 and the sealing strip 2 are restricted to prevent the filler from falling out. Simultaneously, the operator can open the sealing strip 2 during the filler addition stage, and after addition is complete, the sealing strip 2 can be fixed back to the side walls of the first packing hemisphere 1 and the second packing hemisphere 12. The sealing frame 3 is rotatably connected to the side wall of the packing cylinder 11. The operator can more conveniently add filler into the packing cylinder 11 by rotating the sealing frame 3. Also, whenever filler addition is complete, the operator can rotate the sealing frame 3 to the side wall of the packing cylinder 11 and fix the sealing frame 3 to the side wall of the packing cylinder 11 through the fixing hole 32. Multiple sealing strips 31 serve to block the filler and prevent it from falling out. Because they are fixed to... The rotating block 41 on the side wall of the sealing plate 2 is rotatably connected to the fixed block 4 fixed to the side wall of the first packing hemisphere 1 and the packing cylinder 11. The first packing hemisphere 1 and the sealing plate 2, and the second packing hemisphere 12 and the sealing plate 2 will also be rotatably connected. The bottom of the packing cylinder 11 is fixed with a foot support block 5. The operator can use the two foot support blocks 5 to place the packing cylinder 11 on the workbench, thereby preventing the packing cylinder 11 and the first packing hemisphere 1 and the second packing hemisphere 12 connected to the packing cylinder 11 from rolling during the filling stage. The trough 6 opened on the side wall of the sealing plate 2 and the trough 6 opened on the side wall of the packing cylinder 11 can reduce the surface area of ​​the packing cylinder 11 and the sealing plate 2, thereby increasing the area where sewage can enter the inside of the packing balls.The use of stainless steel for the insert rod 15, limit ring 16, return spring 17, and pull ring 18 leverages the high structural strength and corrosion resistance of stainless steel.
