Description

Technical Field

[0001] This utility model relates to the field of biological rotating disc wastewater treatment technology, specifically a disc cluster protection device. Background Technology

[0002] In biological rotating disc wastewater treatment systems, the biofilm carrier (discs) is typically made of corrosion-resistant, wear-resistant materials with a good surface area, such as plastics (e.g., polyethylene, polypropylene, polyamide). These discs, either disc-shaped or sheet-shaped, are assembled into a series of rotating discs suspended in the water. The discs are designed with numerous grooves, holes, or protrusions on their surfaces. These structures significantly increase the specific surface area of ​​the carrier, providing ample space for microbial attachment and reproduction. They also improve the growth environment of the microbial biofilm, enhance microbial metabolism, and increase the degradation efficiency of pollutants. However, in practical applications, due to the uncertainty of water quality and quantity, the disc clusters may exhibit excessive biofilm thickness, leading to tearing and damage at the rim where the circular tube contacts the disc. This severe damage reduces the discs' durability and increases unnecessary economic losses.

[0003] Therefore, it is necessary to develop a disk cluster protection device. Utility Model Content

[0004] The purpose of this invention is to provide a disk cluster protection device to solve the problem of easy damage to disk cluster supports mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a disk cluster protection device, including an operating frame, bearing supports are installed on both sides of the top of the operating frame, a main shaft is installed between the opposite sides of the two sets of bearing supports, and disk clusters are installed on the outer wall of the main shaft.

[0006] The outer walls at both ends of the disk cluster are equipped with steel structure support channels, and disk cluster protection supports A are installed on both outer walls of the steel structure support channels.

[0007] Preferably, both ends of the main shaft are rotatably connected to the inside of the bearing support.

[0008] Preferably, a drive device is installed on the upper part of one side of the outer wall of the operating frame, and the output end of the drive device is fixedly connected to one end of the spindle.

[0009] Preferably, the inner wall of the disk cluster protection bracket A contacts the interior of the disk cluster.

[0010] Preferably, a steel structure support angle steel is installed above the front end of the steel structure support channel steel, and a disc cluster protection support B is installed on both sides of the top of the steel structure support angle steel.

[0011] Preferably, the interior of the disk cluster protection bracket B contacts the outer wall of the disk cluster.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By constructing steel structure support channels at the front and rear ends of the disk cluster, and correspondingly constructing disk cluster protection bracket A on the steel structure support channels inside the disk cluster, the disk cluster is encased, thus providing internal support and protection. Combined with steel structure support angle steel on the steel structure support channels, disk cluster protection bracket B is constructed, encasing the outer perimeter of the disk cluster and providing external support and protection. Through the disk cluster protection brackets A and B, the stress points of the disk cluster are increased, effectively protecting it, minimizing the risk of damage, reducing unnecessary economic losses, and increasing its durability.

[0020] This utility model provides the following technical solution: a disk cluster protection device, please refer to... Figures 1-4The system includes an operating frame 1, with bearing supports 2 installed on both sides of the top of the operating frame 1. A main shaft 3 is installed between the opposite sides of the two sets of bearing supports 2, and the two ends of the main shaft 3 are rotatably connected to the inside of the bearing supports 2. The main shaft 3 on the disc cluster 5 is rotatably connected between the two sets of bearing supports 2 on the operating frame 1. The operating frame 1 is a contact reaction tank with a rectangular planar shape and a semi-circular cross-section. The bottom of the tank is equipped with sludge discharge and venting pipes. The disc cluster 5, i.e., the disc body, is the main body of the biological rotating disc and serves as a carrier for the biofilm. The material is mostly polypropylene, polyethylene, etc., and the shape includes flat plates, corrugated plates, etc. The outer edge shape includes mesh, polygonal, etc., making it... When the disc cluster 5 rotates and is submerged in the sewage, the biofilm adsorbs organic matter. When it rotates out of the water, the water film absorbs oxygen from the air. Under the action of aerobic microbial enzymes, the organic matter is oxidized and decomposed. When the biofilm thickness increases to a certain extent, it will age and peel off, thereby achieving sewage treatment. A drive device 4 is installed on the upper side of one outer wall of the operating frame 1. The output end of the drive device 4 is fixedly connected to one end of the main shaft 3. Disc clusters 5 are installed on the outer wall of the main shaft 3. The drive device 4 is connected to the main shaft 3. The drive device 4 includes two parts: a power device and a reduction device. Generally, it is electrically driven and drives the main shaft 3 to rotate at a suitable speed through the speed change device.

Disk cluster protection brackets A8 are installed on both sides of the outer wall of the steel structure support channels 6. The inner wall of the disk cluster protection brackets A8 contacts the interior of the disk cluster 5. A steel structure support angle steel 7 is installed above the front end of the steel structure support channels 6. Disk cluster protection brackets B9 are installed on both sides of the top of the steel structure support angle steel 7. The interior of the disk cluster protection brackets B9 contacts the outer wall of the disk cluster 5. The steel structure support channels 6 are erected at the front and rear ends of the disk cluster 5, and the steel... The disk cluster protection bracket A8 on the structural support channel steel 6 is correspondingly built inside the disk cluster 5, forming a wrap around the disk cluster 5, thereby achieving internal support and protection for the disk cluster 5. Together with the steel structural support angle steel 7 on the steel structural support channel steel 6, the disk cluster protection bracket B9 is built, and the disk cluster protection bracket B9 wraps around the outside of the disk cluster 5, achieving external support and protection for the disk cluster 5. Through the disk cluster protection bracket B9 and the disk cluster protection bracket A8, the stress points of the disk cluster 5 are increased, effectively playing a protective role.

[0022] Working Principle: In using this invention, the main shaft 3 on the disc cluster 5 is rotatably connected between two sets of bearing supports 2 on the operating frame 1. The operating frame 1 is a contact reaction tank with a rectangular planar shape and a semi-circular cross-section. The bottom of the tank is equipped with sludge discharge and venting pipes. The disc cluster 5, i.e., the disc body, is the main body of the biological rotating disc and serves as the carrier of the biofilm. The material is mostly polypropylene, polyethylene, etc., and the shape includes flat plates, corrugated plates, etc. The outer edge shape includes mesh, polygonal, etc. When the disc cluster 5 rotates and is immersed in sewage, the biofilm adsorbs organic matter. When it rotates out of the water, the water film absorbs oxygen from the air. Under the action of aerobic microbial enzymes, the organic matter is oxidized and decomposed. When the biofilm thickness increases to a certain extent, it will age and peel off, thereby achieving sewage treatment. By connecting the drive device 4 to the main shaft 3, the drive device 4 includes a power unit and a reduction gear. The device consists of two parts, typically electrically driven. A speed-changing device drives the main shaft 3 to rotate at a suitable speed. A steel structure support channel 6 is erected at the front and rear ends of the disk cluster 5, and a corresponding disk cluster protective bracket A8 is erected inside the disk cluster 5, thus encasing the disk cluster 5 and providing internal support and protection. A disk cluster protective bracket B9 is then erected using the steel structure support angle steel 7 on the steel structure support channel 6, encasing the disk cluster 5 externally and providing external support and protection. The disk cluster protective brackets B9 and A8 increase the stress points on the disk cluster 5, effectively protecting it, minimizing the risk of damage, reducing unnecessary economic losses, and increasing its durability.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation.
