Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of movable bed biofilm reactors, in particular to a movable bed biofilm reactor. Background Art
[0002] The Moving-Bed Biofilm Reactor (MBBR) is another innovative biofilm reactor that has attracted much attention from researchers in recent years. It was developed to solve the complex operations of fixed-bed reactors requiring regular backwashing, fluidized beds requiring carrier fluidization, and submerged biofilters requiring filter media cleaning and aerator replacement when clogged. It also retains the characteristics of traditional biofilm methods such as resistance to shock loads, low sludge production, and long sludge age. The MBBR system includes a reactor filled with a special mobile carrier, usually a plastic filler such as HDPE (high-density polyethylene). These fillers provide a large surface area, which is conducive to bacterial attachment and growth. When wastewater passes through the reactor, bacteria attach to the surface of the filler to form a biofilm, which converts wastes such as organic matter and ammonia nitrogen into relatively stable wastewater through biodegradation.
[0003] When moving, the movable bed biofilm reactor needs to be carried by external force, which makes the movement more troublesome. Secondly, after the biofilm reactor moves, due to the action of rollers, the biofilm reactor will move by itself due to gravity and other reasons. Finally, after the biofilm reactor moves to the designated position, since the biofilm reactor is heavy, there is a lack of supporting device on the outside of the reactor. Therefore, a movable bed biofilm reactor is proposed to address the above problems. Utility Model Content

[0026] Working process: The device is a movable biofilm reactor. A vertical plate 2 is fixedly connected to the bottom end of the reactor 1. A straight shaft 9 is fixedly connected between the two vertical plates 2. A roller 10 is rotatably connected to the outer side of the straight shaft 9. A locking hole 17 penetrating the roller 10 is provided on one side of the roller 10. A fixed shell 3 is fixedly connected to one side of the vertical plate 2. A positioning hole 4 penetrating the fixed shell 3 is provided on the outer side of the fixed shell 3. A pin rod 5 slides inside the fixed shell 3. A limiting plate 6 is fixedly connected to the outer side of the pin rod 5. A cross bar 7 perpendicular to the pin rod 5 is also fixedly connected to the outer side of the pin rod 5. The outer side of the pin rod 5 is located on the cross bar A spring 8 is provided between 7 and the vertical plate 2, a bracket 11 is fixedly connected to the outside of the reactor 1, a screw 12 is threadedly connected to the inside of the bracket 11, a threaded block 13 is fixedly connected to the middle of the outside of the screw 12, a threaded tube 14 is threadedly connected to the outside of the screw 12 near the bottom end, a support plate 15 is fixedly connected to the bottom end of the threaded tube 14, and a plurality of rubber blocks 16 are fixedly connected to the bottom end of the support plate 15. When the position of the reactor 1 needs to be changed, the support plate 15 and the rubber block 16 are first raised by the screw 12, the roller 10 contacts the ground, and the pin 5 is rotated to make the cross bar 7 can slide out of the positioning hole 4, and under the elastic force of the spring 8, the other end of the pin rod 5 leaves the locking hole 17 of the roller 10.

Under the action of the pin rod 5, the roller 10 will not rotate, and the position of the reactor 1 can be positioned. By rotating the screw 12 through the threaded block 13, the threaded tube 14, the support plate 15 and the rubber block 16 can be lowered.

The rubber block 16 can provide a shock-absorbing effect for the reactor 1 to avoid damage or abnormality of the components of the reactor 1 caused by vibration. Moreover, each supporting device works independently, and the horizontality of the reactor 1 can be adjusted to keep the reactor 1 in a stable state, thereby ensuring the normal operation of the reactor 1.
