Abstract
Description
Technical Field
[0001] This utility model relates to the field of biological rotating disc wastewater treatment technology, specifically to a segmented biological rotating disc. Background Technology
[0002] A biological rotating disc is a biofilm process used for wastewater treatment, belonging to the category of aerobic biological treatment technology. Its core structure consists of a series of discs arranged in parallel on a rotating shaft. The discs are partially submerged in wastewater, and slow rotation causes the discs to alternately contact wastewater and air. The microbial film growing on the disc surface adsorbs and degrades organic matter in the wastewater. A segmented biological rotating disc is an improved type, where the system is divided into several segments (usually 3-4 segments), each consisting of a set of discs. These segments are separated by partitions, forming independent reaction units. Each segment can control different environmental conditions (such as dissolved oxygen, microbial community, organic load, etc.), achieving a tiered division of functions.
[0003] In actual wastewater treatment processes, when water quality fluctuates, it is necessary to adjust the number of discs in each segment of the segmented biological rotating disc to adjust the specific treatment process and thus match the current water quality. However, in existing segmented biological rotating discs, the discs on each segment are fixedly connected to the rotating shaft, and the number of discs can only be increased or decreased by disassembling and assembling the discs in each segment individually. Therefore, the process of adjusting the number of discs in each segment of the existing segmented biological rotating disc is too cumbersome, especially when there are multiple fluctuations in water quality, requiring multiple adjustments of the number of discs, which is time-consuming, labor-intensive, and reduces wastewater treatment efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a solution that solves the problem of the overly cumbersome process of adjusting the number of discs in each segment of a segmented biological rotating disk. By setting an intermediate slide rail between the first mounting part and the second mounting part, the discs move back and forth along the intermediate slide rail between the first mounting part and the second mounting part, thereby conveniently adjusting the number of the first disc group and the second disc group.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a segmented biological rotating disc, comprising a rotating shaft and discs, wherein the rotating shaft is provided with at least a first mounting portion and a second mounting portion spaced apart from each other, a plurality of discs are disposed on the first mounting portion to form a first disc group, and a plurality of discs are disposed on the second mounting portion to form a second disc group, a first fixing plate is provided on the first mounting portion, and a second fixing plate is provided on the second mounting portion, both the first fixing plate and the second fixing plate being detachably connected to the discs, an intermediate slide rail is provided between the first mounting portion and the second mounting portion, and a sliding portion is provided on the discs to slide in cooperation with the intermediate slide rail, so that the discs can move from the first mounting portion to the second mounting portion or from the second mounting portion to the first mounting portion.
[0006] In one embodiment, a plurality of first fixing plates are arranged at intervals along the axial direction, a plurality of second fixing plates are arranged at intervals along the axial direction, and the disk is provided with clearance openings along the axial direction corresponding to the first fixing plates and the second fixing plates, so that the first fixing plates and the second fixing plates can pass through.
[0007] In one embodiment, a plurality of first fixing plates are aligned with each other along the axial direction, and a plurality of second fixing plates are aligned with each other along the axial direction, so that the disk can move when the clearance opening of the disk is aligned with the first fixing plate or the second fixing plate, and the disk is fixed when the clearance opening of the disk intersects with the first fixing plate or the second fixing plate.
[0008] In one embodiment, a plurality of first fixing plates are distributed at different positions in the circumferential direction of the first mounting portion, and a plurality of second fixing plates are distributed at different positions in the circumferential direction of the second mounting portion. The disk is provided with a plurality of clearance openings, the number of clearance openings being less than the number of first fixing plates and the number of second fixing plates, so that the disk avoids a plurality of first fixing plates or second fixing plates when moving axially.
[0009] In one embodiment, the first mounting part is provided with a first slide rail, the second mounting part is provided with a second slide rail, and the sliding part on the disc is slidably engaged with the first slide rail, the second slide rail and the intermediate slide rail to restrict the rotation of the disc.
[0010] In one embodiment, the first fixing plate and the second fixing plate are fixedly connected to the disk by bolts and nuts, and the first fixing plate, the second fixing plate and the disk are provided with fixing holes for the bolts to pass through.
[0011] In one embodiment, a single first fixing plate includes two first sub-plates symmetrical about the axis of rotation, and a single second fixing plate includes two second sub-plates symmetrical about the axis of rotation, so that the disk is fixed at two points by the first fixing plate or the second fixing plate.
[0012] The advantages of this application compared to the prior art are:
[0013] In this embodiment, the first mounting part and the second mounting part are connected by an intermediate slide rail, so that the discs in the first disc group and the second disc group can move along the slide rail, realizing the transfer of discs between the first mounting part and the second mounting part. This increases or decreases the number of discs in the first disc group and the second disc group, realizing the adjustment of the number of discs in each segment of the segmented biological rotating disc, thereby preparing for the adjustment of the sewage treatment process to adapt to the current water quality conditions and improve the overall sewage treatment effect.

[0023] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.
[0024] Please refer to Figure 1 This application discloses a segmented biological rotating disk, including a rotating shaft 100 and disks 200. The rotating shaft 100 has at least two spaced-apart first mounting portions 110 and second mounting portions 120. Multiple disks 200 are disposed on the first mounting portions 110 to form a first disk group 210, and multiple disks 200 are disposed on the second mounting portions 120 to form a first disk group 220. This divides the rotating shaft 100 into at least two working areas for the disks 200: one for the first disk group 210 and the other for the first disk group 220, forming a segmented biological rotating disk. In some embodiments, the rotating shaft 100 may have an additional number of mounting portions, with each mounting portion having a group of disks 200, forming multiple working areas for the disks 200. This application description primarily uses the first mounting portion 110 and the second mounting portion 120 as examples.
[0025] The difference between this embodiment and the prior art is that the first mounting part 110 is provided with a first fixing plate 111, and the second mounting part 120 is provided with a second fixing plate 121. Both the first fixing plate 111 and the second fixing plate 121 are detachably connected to the disk 200. That is, the disk 200 located in the first mounting part 110 is fixed to the first mounting part 110 by being detachably connected to the first fixing plate 111, and the disk 200 located in the second mounting part 120 is fixed to the second mounting part 120 by being detachably connected to the second fixing plate 121. An intermediate slide rail 130 is provided between the first mounting part 110 and the second mounting part 120. The disk 200 is provided with a sliding part 230 that slides with the intermediate slide rail 130. In this way, the disk 200 can move along the intermediate slide rail 130 through the sliding part 230. The disk 200 can move from the first mounting part 110 to the second mounting part 120, or from the second mounting part 120 to the first mounting part 110. In this embodiment, the first mounting part 110 and the second mounting part 120 are connected by an intermediate slide rail 130, so that the discs 200 in the first disc group 210 and the first disc group 220 can move along the slide rail, realizing the transfer of the discs 200 between the first mounting part 110 and the second mounting part 120. This increases or decreases the number of discs 200 in the first disc group 210 and the first disc group 220, realizing the adjustment of the number of discs 200 in each segment of the segmented biological rotating disc, thereby preparing for the adjustment of the sewage treatment process to adapt to the current water quality conditions and improve the overall sewage treatment effect. In this embodiment, adjusting the number of discs 200 on the segmented biological rotating disc does not require removing individual discs 200 from the rotating shaft 100. Simply disconnecting the disc 200 from the first fixing plate 111 or the second fixing plate 121 allows the disc 200 to move between the first mounting part 110 and the second mounting part 120 for transfer. Once the disc 200 has reached the target area, it is reconnected to the corresponding first fixing plate 111 or second fixing plate 121. This simple and convenient adjustment process saves time and effort, reducing the impact on overall wastewater treatment efficiency. In some embodiments, the intermediate slide rail 130 is a groove or protrusion structure located on the rotating shaft 100, and the sliding part 230 is a groove or protrusion structure that mates with the intermediate slide rail 130.
[0026] Please refer to Figure 1 , Figure 2In this embodiment of the application, it is preferable that a plurality of first fixing plates 111 are arranged at intervals along the axial direction, a plurality of second fixing plates 121 are arranged at intervals along the axial direction, and the disc 200 is provided with a clearance opening 240 corresponding to the first fixing plates 111 and the second fixing plates 121 along the axial direction, so that the first fixing plates 111 and the second fixing plates 121 can pass through. Specifically, the disk 200 has an inner hole in the middle for fitting onto the rotating shaft 100. The first fixing plate 111 and the second fixing plate 121 are respectively located on the first mounting part 110 and the second mounting part 120 of the rotating shaft 100. Therefore, the clearance opening 240 is located on the side of the disk 200 near the inner hole and communicates with the inner hole. When the disk 200 needs to be moved, if the first fixing plate 111 or the second fixing plate 121 located on the moving path of the disk 200 does not correspond to the clearance opening 240, the disk 200 is rotated until its clearance opening 240 corresponds axially to the first fixing plate 111 or the second fixing plate 121 that needs to be passed, so that the first fixing plate 111 or the second fixing plate 121 that needs to be passed can pass through the clearance opening 240 without obstructing the disk 200. This allows the disk 200 to pass over the fixing plate (first fixing plate 111 or second fixing plate 121), thereby realizing the smooth movement of the disk 200. Throughout the movement of the disk 200, the above operation is performed each time it encounters the nearest first fixed plate 111 or second fixed plate 121 on its movement path, so that the disk 200 can pass over each first fixed plate 111 or second fixed plate 121 that needs to be passed. When the disk 200 moves to the target position, if the clearance opening 240 of the disk 200 corresponds axially with the first fixed plate 111 or second fixed plate 121 at the target position, the disk 200 is rotated so that the clearance opening 240 is staggered with the first fixed plate 111 or second fixed plate 121 at the target position, so that the disk 200 is blocked axially by the first fixed plate 111 or second fixed plate 121 at the target position. Then, the disk 200 is detachably connected to the first fixed plate 111 or second fixed plate 121 at the target position, thereby fixing the disk 200 on the first mounting part 110 or second mounting part 120 of the rotating shaft 100.
[0027] For further details, please refer to Figure 1In one embodiment of this application, it is preferred that a plurality of first fixing plates 111 are aligned with each other along the axial direction, and a plurality of second fixing plates 121 are aligned with each other along the axial direction, so that the disk 200 can move when the clearance opening 240 of the disk 200 is aligned with the first fixing plate 111 or the second fixing plate 121, and the disk 200 is fixed when the clearance opening 240 of the disk 200 intersects with the first fixing plate 111 or the second fixing plate 121. In this embodiment, all the first fixing plates 111 on the first mounting part 110 are aligned with each other along the axial direction, and all the second fixing plates 121 on the second mounting part 120 are aligned with each other along the axial direction. Thus, when the disc 200 moves on the first mounting part 110, only one rotation is needed to align the clearance opening 240 of the disc 200 with all the first fixing plates 111. Similarly, when the disc 200 moves on the second mounting part 120, only one rotation is needed to align the clearance opening 240 of the disc 200 with all the second fixing plates 121. This allows the disc 200 to move simultaneously on both the first mounting part 110 and the second mounting part 120 without needing to rotate it again to adjust the position of its clearance opening 240. Therefore, the ease of moving the disc 200 is further improved, thereby increasing the efficiency of adjusting the number of discs 200 on the first mounting part 110 and the second mounting part 120.
[0028] Please refer to Figure 3 , Figure 4Furthermore, in one embodiment of this application, based on the axially spaced arrangement of multiple first fixing plates 111 and multiple second fixing plates 121, it is further preferred that the multiple first fixing plates 111 are distributed at different positions in the circumferential direction of the first mounting portion 110 (the arrangement of the multiple first fixing plates 111 in the circumferential direction of the first mounting portion 110 when viewed from an axial perspective), and the multiple second fixing plates 121 are distributed at different positions in the circumferential direction of the second mounting portion 120 (the arrangement of the multiple second fixing plates 121 in the circumferential direction of the second mounting portion 120 when viewed from an axial perspective). The disk 200 is provided with multiple clearance openings 240, the number of clearance openings 240 being less than the number of first fixing plates 111 and the number of second fixing plates 121, so that the disk 200 avoids the multiple first fixing plates 111 or second fixing plates 121 when moving axially. In this embodiment, the disk 200 is provided with a plurality of clearance openings 240, each clearance opening 240 corresponding to one of the first fixing plates 111 and one of the second fixing plates 121. This allows the disk 200 to pass over multiple first fixing plates 111 or multiple second fixing plates 121 without rotating the disk 200 to adjust the position of the clearance openings 240 when passing over these first fixing plates 111 or second fixing plates 121 that correspond to the clearance openings 240. In addition, the number of clearance openings 240 is less than the number of first fixing plates 111 and the number of second fixing plates 121. That is, at least one first fixing plate 111 and one second fixing plate 121 do not have a corresponding clearance opening 240 on the disk 200, so as to block the disk 200 and be fixedly connected to the disk 200. Therefore, in this embodiment, when the disk 200 moves on the first mounting part 110 or the second mounting part 120, there is a corresponding clearance opening 240. The first fixing plate 111 or the second fixing plate 121 can be directly passed over. When the moving disk 200 is blocked by a first fixing plate 111 or the second fixing plate 121, it means that the disk 200 has moved to the target position and the disk 200 needs to be connected to the first fixing plate 111 or the second fixing plate 121 that blocks it to achieve fixation. In this embodiment, there is at least one non-corresponding clearance opening 240 between different disks 200. Thus, the first fixing plate 111 or the second fixing plate 121 that would block one disk 200 will not block another disk 200. This allows different disks 200 to be blocked and fixed on the first mounting part 110 by different first fixing plates 111, and different disks 200 to be blocked and fixed on the second mounting part 120 by different second fixing plates 121. For the movement of each disk 200, it only needs to be moved once until it is blocked by one of the first fixing plates 111 or the second fixing plate 121. There is no need to rotate the disk 200 on the first mounting part 110 and the second mounting part 120 to adjust the position of the clearance opening 240, which can also improve the efficiency of adjusting the number of disks 200 on the first mounting part 110 and the second mounting part 120.
[0029] Since the disk 200 does not need to rotate on the first mounting portion 110 and the second mounting portion 120 in the previous embodiment of this application (the embodiment with multiple clearance slots 240 on the disk 200), based on this embodiment, it is further preferred that the first mounting portion 110 is provided with a first slide rail, the second mounting portion 120 is provided with a second slide rail, and the sliding portion 230 on the disk 200 is slidably engaged with the first slide rail, the second slide rail, and the intermediate slide rail 130 to restrict the rotation of the disk 200. In this way, the disk 200 can be circumferentially limited on both the first mounting portion 110 and the second mounting portion 120, reducing the load on the detachable connection between the disk 200 and the first fixing plate 111 and the second fixing plate 121 in the circumferential direction, improving the stability and service life of the detachable connection structure, and improving the smoothness of the movement of the disk 200 on the first mounting portion 110 and the second mounting portion 120, making operation more labor-saving. Furthermore, it is preferable that the first slide rail, the second slide rail, and the intermediate slide rail 130 are connected to each other along the axial direction of the rotating shaft 100 to form a complete elongated slide rail.
[0030] In this embodiment, the first fixing plate 111 and the second fixing plate 121 are preferably fixedly connected to the disk 200 by bolts 320 and nuts. The first fixing plate 111, the second fixing plate 121, and the disk 200 are provided with fixing holes 310 for the bolts 320 to pass through. When the disk 200 abuts against one of the first fixing plates 111 or the second fixing plate 121, the fixing holes 310 of both plates correspond, and after the bolts 320 are passed through, they are tightened with nuts, thus fixing the disk 200 on the rotating shaft 100. When it is necessary to move the disk 200, the nuts are loosened and the bolts 320 are pulled out, disengaging the disk 200 from the first fixing plate 111 or the second fixing plate 121, allowing the disk 200 to move and adjust the number of disks 200 on the first mounting part 110 and the second mounting part 120, making operation convenient.
[0031] Furthermore, in one embodiment of this application, a single first fixing plate 111 preferably includes two first sub-plates that are symmetrical about the axis of rotation 100, and a single second fixing plate 121 includes two second sub-plates that are symmetrical about the axis of rotation 100, so that the disk 200 is fixed at two points by the first fixing plate 111 or the second fixing plate 121, thereby improving the installation stability of the disk 200 on the axis of rotation 100 and thus improving the reliability of the disk 200 during the operation of the biological rotating disk.
[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
