Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an automatic cleaning MBBR packing compartment fixing device. Background Technology
[0002] The MBBR (Moving Bed Biofilm Reactor) process significantly enhances biomass and biodiversity by adding a specific amount of suspended carrier packing material to the reactor, thereby accelerating treatment efficiency. Compared to traditional wastewater treatment methods, this process not only simultaneously achieves nitrification and denitrification in the aerobic zone of the biological treatment tank, but also adapts to complex conditions such as changes in ambient temperature and wastewater composition, significantly improving wastewater treatment efficiency. However, in practical applications, MBBR packing material, due to its density being close to that of water, is prone to aggregation and clogging with the water flow, resulting in uneven distribution and affecting the overall treatment effect. Although existing separation devices alleviate this problem to some extent, these devices, exposed to wastewater for extended periods, are prone to accumulating fouling, hindering normal water flow. Therefore, developing an automatically cleaning MBBR packing material zoning and fixing device is crucial to ensure effective packing material distribution and smooth water flow.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0022] This utility model provides, for example Figure 1 , Figure 2 The automatically cleaning MBBR packing compartment fixing device shown includes:
[0023] Several partition supports 1 include tracks 11 and grid plates 12. The tracks 11 are arranged in parallel and fixed on both sides of the biological tank. The grid plates 12 are made of stainless steel and are vertically fixed at the bottom of the corresponding tracks 11 to divide the biological tank into several areas. The mesh size of the grid plates 12 is slightly smaller than the diameter of the MBBR packing.
[0024] The connecting frame 2 is vertically arranged and slidably connected to the track 11, and is used to make horizontal parallel movement on the track 11. The bottom of the connecting frame 2 is fixedly connected with a connecting rod 3 corresponding to the number of tracks 11. The connecting rod 3 is arranged on the upstream side of the water flow of the grid plate 12.
[0025] A power unit is used to drive the connecting frame 2 to slide on the track 11;
[0026] The cleaning device 5 includes a mounting plate 51 and brush bristles 52. The mounting plate 51 is fixedly connected to the connecting rod 3, and the brush bristles 52 are fixedly connected to the mounting plate 51 for cleaning the upstream side of the grid plate 12.
[0027] In operation, the connecting frame 2 is driven by a power unit to move horizontally parallel to the track 11. The connecting rod 3 at the bottom of the connecting frame 2 is connected to the mounting plate 51, on which brush bristles 52 are installed, and is located on the upstream side of the grid plate 12. When the power unit is started, the connecting frame 2 drives the brush bristles 52 to slide on the surface of the grid plate 12, removing dirt and MBBR packing adhering to it, ensuring that the pores of the grid plate 12 are unobstructed, allowing water to flow freely through each area, maintaining the optimal working condition of the packing and the efficient operation of the wastewater treatment system. This design not only solves the problem of packing blockage but also extends the service life of the equipment and reduces the frequency of maintenance.
[0028] To facilitate the smooth sliding of the drive connecting frame 2 on the track 11, such as Figure 1 , 2 As shown, the power device includes a motor and a rotating shaft 4. The drive shaft of the motor is connected to the rotating shaft 4. The drive shaft is rotatably installed on both sides of the biochemical tank. The drive shaft has an external thread. The top of the connecting frame 2 is fixedly connected to a fixing plate 6. The fixing plate 6 has a threaded hole that mates with the thread of the drive shaft. The drive shaft drives the connecting frame 2 to slide on the track 11.
[0029] To ensure stable sliding of the connecting frame 2, such as Figure 1 , 2As shown, a threaded cylinder 7 is fixedly connected to the fixed plate 6, and the threaded cylinder 7 is threadedly engaged with the drive shaft.
[0030] To facilitate the sliding of the connecting bracket 2 and reduce friction, such as Figure 2 As shown, a groove 13 is provided in the track 11, and a roller 8 that cooperates with the groove 13 is installed on the connecting frame 2.
[0031] In order to limit the sliding of the connecting bracket 2 and reduce friction, such as Figure 2 As shown, limit wheels 81 are installed on both sides of the roller 8. The limit wheels 81 are located in the slide groove 13 and limit the sliding direction of the connecting frame 2, so as to facilitate the linear sliding of the connecting frame 2.
[0032] To improve the stability of connecting rod 3, such as Figure 2 As shown, a diagonal brace 9 is fixedly connected between the connecting rod 3 and the connecting frame 2.
[0033] For easy replacement of cleaning device 5, such as Figure 2 As shown, the mounting plate 51 is detachably fixed to the connecting rod 3 by bolts 10, and the connecting rod 3 is parallel to the grid plate 12 and inclined.
