Description

Technical Field

[0001] This utility model relates to the field of granular sludge, and in particular to an anaerobic granular sludge capture device. Background Technology

[0002] Granular sludge is a spherical or elliptical aggregate of sludge formed by microorganisms through self-aggregation. It is mainly divided into two categories: anaerobic granular sludge and aerobic granular sludge. Aerobic granular sludge has an outer aerobic zone and an inner anaerobic zone, while anaerobic granular sludge forms a stable micro-ecosystem. It exhibits high efficiency in COD removal, nitrogen and phosphorus removal, and heavy metal adsorption. Optimizing reactor structure and operating parameters can improve treatment efficiency and reduce energy consumption.

[0003] Anaerobic granular sludge is a granular biological aggregate formed by the aggregation and entanglement of a large number of anaerobic microorganisms (including bacteria, archaea, etc.) in an anaerobic biological treatment system. It has good settling performance and efficient anaerobic degradation capacity.

[0004] Existing anaerobic granular sludge refers to the natural solidification of microorganisms through the formation of granular sludge, which increases the stability of the process and results in low suspended solids (SS) content in the effluent. However, sludge particles are often lost with the water flow during operation. To reduce the loss of sludge particles, an anaerobic granular sludge trap is proposed to solve the above problems. Utility Model Content

[0010] As a further description of the above technical solution: the filter plate has a sliding groove inside, and the size of the sliding groove inside the filter plate matches the roller.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 2This utility model provides an embodiment of an anaerobic granular sludge trap, comprising a sludge trap body 1, with a multi-layer sludge filter device 4 disposed inside the sludge trap body 1; the multi-layer sludge filter device 4 includes a housing 41, with a support leg 42 fixedly connected to the side of the housing 41, a motor 45 disposed on the side of the housing 41, a main rotating rod 46 fixedly connected to the front of the output shaft of the motor 45, a storage tank 47 fixedly connected to the side of the main rotating rod 46 away from the motor 45, a permeation plate 48 fixedly connected to the side of the storage tank 47, a water storage layer 49 fixedly connected inside the housing 41, a roller 410 slidably connected to the side of the main rotating rod 46, a filter plate 411 slidably connected to the side of the roller 410, and multiple filter plates 411 arranged in an array inside the housing 41, with a total of multiple filter plates 41 disposed inside the housing 41. 1. The filter plates 411 have different sizes of holes and grooves. The different hole and groove settings of the multiple filter plates 411 make it easier to collect the residual sludge particles of different sizes in each layer and avoid excessive residue on one layer of filter plate 411, which will cause blockage. The filter plates 411 have sliding grooves inside, and the size of the sliding grooves inside the filter plates 411 matches the rollers 410. A water storage layer 412 is fixedly connected to the side of the filter plates 411. The side of the water storage layer 412 away from the filter plates 411 is fixedly connected to the inside of the box 41. This design ensures that the water storage layer 412 will not rotate when the filter plates 411 rotate. A guide plate 413 is fixedly connected to the inside of the box 41. The guide plate 413 has multiple layers of small holes and grooves of different regularities inside. A storage frame 414 is snapped into the inside of the box 41. A portable disassembly device 5 is set inside the storage frame 414.

[0025] Reference Figure 3 - Figure 4 An observation port 2 is fixedly connected to the surface of the sludge capture body 1, and a fixing bolt 3 is threadedly connected to the surface of the observation port 2. An external water pipe 43 is fixedly connected to the side of the housing 41, and a water outlet pipe 44 is fixedly connected to the side of the housing 41 away from the external water pipe 43. The portable disassembly device 5 includes a hollow slot 1 51 and a hollow slot 2 52. The hollow slot 1 51 is opened inside the housing 41, and a hollow slot 1 51 is opened on both sides inside the housing 41. The hollow slot 2 52 is opened inside the storage frame 414, and a hollow slot 1 51 is opened on both sides inside the storage frame 414. Each of the two hollow slots 51 and 52 is designed to facilitate the disassembly of the storage frame 414. The hollow slot 51 is fixedly connected to a limit block 53. The hollow slot 52 is elastically connected to a block 55 via a spring 54. One side of the spring 54 is fixedly connected to the inside of the storage frame 414, and the other side is fixedly connected to the side of the block 55. This design allows the spring 54 to drive the block 55 to slide inside the storage frame 414. A pressure plate 56 is fixedly connected to the side of the block 55.

[0026] Working principle: When the sludge capture unit 1 starts operating, the bacteria are first stored inside the storage tank 47. Water is injected into the tank 41 through the external water pipe 43. The water accumulates in the first water storage layer 49 and flows through the permeation plate 48 into the storage tank 47 for anaerobic biological treatment. The bacteria aggregate to form granular bioaggregates, i.e., granular sludge. When the water flows out of the storage tank 47, some sludge is inevitably carried out. The sludge flows to the surface of the filter plate 411 and the surface of the second water storage layer 412 according to the water flow. The motor 4... 5 drives the main rotating rod 46 to rotate, which in turn drives the filter plate 411 to rotate through the sliding of the roller 410. The force generated by the rotation drives the water and some sludge to continue flowing to the bottom. The different slots of the multiple filter plates 411 result in different sizes of sludge remaining on their surfaces. When the final residual sludge and water flow, they will flow to the guide plate 413. The design of the multiple irregular holes and grooves inside the guide plate 413 allows water to seep out, and the sludge will flow to the storage frame 414 according to the inclined guide plate 413. The water will be discharged through the outlet pipe 44, thereby achieving the effect of capturing sludge particles and preventing their loss.

[0027] When the storage box 414 is to be removed, first press the pressure plate 56, causing the pressure plate 56 to slide the locking block 55. The locking block 55 slides outward through the hollow groove 51 inside the box 41 via the spring 54, causing the limiting locking block 53 to lose its engagement with the locking block 55. This achieves the effect of portable removal of the storage box 47. When the storage box 47 is to be reinstalled, simply push the storage box 47. Its locking block 55 will slide into the hollow groove 52 due to its shape design. When it slides into the inside of the box 41, it will pop out inside the hollow groove 51 and engage with the side of the limiting locking block 53, thus achieving the engagement effect.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
