Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment, and in particular to a sewage treatment bottom-sinking agitator. Background Technology

[0002] Bottom-mounted agitators are important mixing machines in wastewater treatment, suitable for urban and rural wastewater treatment plants. They are widely used in anaerobic tanks, sedimentation tanks, and aeration tanks, and are essential equipment in municipal and industrial wastewater treatment processes. Forced-propulsion agitators are installed in the biological treatment tanks of wastewater treatment plants to forcibly agitate the sludge and prevent sludge sedimentation. Existing agitators mainly consist of a motor, impeller, and installation system to achieve the process requirements of solid-liquid two-phase flow and homogeneous and fluidized solid-liquid mixtures in the biological treatment process.

[0003] Existing bottom-mounted agitators for wastewater treatment tend to float and sway in the wastewater treatment tank, making it difficult to stably sink to the bottom of the tank and effectively rotate and agitate the sludge at the bottom. Furthermore, during the agitation of sludge at the bottom of the tank, the agitator is prone to shaking and tipping over, resulting in an unbalanced and unstable position that affects the agitator's ability to agitate the sludge.

[0004] Therefore, we designed a bottom-mounted agitator for wastewater treatment to meet the needs of practical applications. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a bottom-mounted agitator for wastewater treatment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a wastewater treatment bottom-sinking agitator, including an installation cylinder, a support cylinder installed in the middle of the installation cylinder, an installation block rotatably installed at the bottom end of the support cylinder, agitating blades uniformly fixed on the surface of the installation block, a connecting ring fixed at the bottom end of the surface of the support cylinder, a reinforcing plate uniformly fixed between the surface of the connecting ring and the top end of the installation cylinder, a cylinder cover installed at the top end of the support cylinder, a bracket fixed on the side of the support cylinder, and a wire attached to the surface of the bracket. A connecting block is fixed to the bottom outer side of the mounting cylinder. An overlapping plate is rotatably mounted on the outer side of the connecting block. An extension plate is mounted on the outer end of the overlapping plate. A connecting plate is fixed to the outer end of the extension plate.

[0007] In detail, both the mounting cylinder and the support cylinder are cylindrical structures, and the mounting block is a hemispherical structure with a rotating column fixed at the top center. A motor is mounted on the top of the rotating column, and the motor is fixedly installed at the bottom inside the support cylinder. A controller for controlling the motor is fixed at the top inside the support cylinder and connected to the power supply via the wire.

The rotating block is slidably inserted into the rotating groove. A first screw slides through the inside of the first connecting hole and the second connecting hole and is fastened and connected with a nut.

[0010] In detail, the bottom end of the overlapping plate has an adjustment groove, and the inner end of the extension plate is slidably inserted into the adjustment groove. Both the adjustment groove and the extension plate are rectangular structures and are horizontally arranged.

[0011] In detail, the outer ends of the adjustment groove are provided with third connecting holes on both sides, and the surface of the extension plate is provided with fourth connecting holes evenly. A second screw slides through the third connecting hole and the fourth connecting hole and is fastened and connected with a nut.

[0012] In detail, the connecting plate is vertically fixed to the outer end of the extension plate, and its two ends are provided with fifth connecting holes that connect to the bottom of the sewage treatment tank. The bottom ends of the connecting plate, the extension plate, the overlapping plate and the mounting cylinder are all horizontal and flush.

Connecting blocks are evenly fixed at the bottom outer side of the installation cylinder, and overlapping plates are installed through the first screw and the rotating block. After the overlapping plates are rotated and unfolded, they are laid horizontally around the installation cylinder to balance and stabilize the installation cylinder and the support cylinder, and to keep the stirring blades rotating stably to stir the sludge. An adjustment groove is opened at the bottom of the lap plate, and the inner end of the extension plate is inserted into the adjustment groove. The extension plate and the lap plate are fastened together by the second screw, so that the length of the extension plate extending out of the lap plate can be adjusted, thereby adjusting the landing area of ​​the bottom of the outer side of the mounting cylinder and improving the balance and stability of the bottom of the mounting cylinder and the support cylinder. A connecting plate is fixed at the outer end of the extension plate, and a fifth connecting hole is opened at both ends of the connecting plate for fastening connection with the bottom of the sewage treatment tank through bolts. This ensures the stable installation of the connecting plate, extension plate, and overlapping plate, facilitates the fastening and stable installation of the support cylinder and installation cylinder, and maintains the stable rotation of the mixing blades to mix the sludge.

[0014] The design scheme proposed in this utility model has the following beneficial effects in application: 1. The stirring blade is rotatably installed inside the bottom of the support cylinder. The rotation is controlled by a motor inside the support cylinder. The cylinder cover is installed on the outside of the stirring blade to facilitate the stirring blade to stir the sludge at the bottom of the sewage treatment tank. 2.
