Description

Technical Field

[0001] This utility model belongs to the field of oxidation ditch, and specifically relates to a device for cleaning scum and duckweed in oxidation ditch. Background Technology

[0002] Oxidation ditches are a variation of the activated sludge process. Their aeration tanks are closed ditch-shaped, so their hydraulic flow pattern differs from that of the traditional activated sludge process. They are interconnected circulating aeration ditches where wastewater seeps in and is purified. The earliest oxidation ditches were not built with reinforced concrete, but were earthen ditches with slope protection. They were intermittently filled with water and intermittently aerated. In this respect, oxidation ditches were the earliest technology for treating wastewater using a batch process.

[0003] Chinese Patent No. CN216808300U discloses a novel river oxidation ditch device. It includes an oxidation ditch body with a partition wall at its center. A support column is bolted to the axial center of the bottom inner wall of the oxidation ditch body. An installation groove is formed at the top of the support column, and a motor is bolted inside the installation groove. A rotating base is bolted to the output end of the motor. This invention uses a motor to drive a rotatable grille or screen to clean and collect floating debris and duckweed in the water. The dredging device can be installed in a location with a narrow water surface between the anaerobic and anoxic sections.

[0004] As can be seen from the above structure, a rotating grille or screen driven by a motor is used to clean and collect floating scum and duckweed in the water. The dredging device can be set in a position where the water flow surface is narrow in the anaerobic and anoxic sections. The structure is novel, the design is reasonable, and it is highly practical. In the process of sewage treatment, a lot of floating scum and duckweed form in the anaerobic or anoxic sections of the oxidation ditch. If it is not cleaned in time, it will affect the exchange of gas and liquid phases, thus greatly reducing the purification effect of sewage. Therefore, a large particulate matter filtration device for oxidation ditches is proposed. Utility Model Content

A feeding assembly is provided on the inner side of the installation plate, and a scooping assembly is also provided on the inner side of the installation plate.

[0009] The inner side of the mounting plate is fixedly connected to a discharge shell, the inside of which is rotatably connected to a conveying auger, and the outer side of which is fixedly connected to a discharge pipe that penetrates the mounting plate.

[0010] As a preferred technical solution, a blocking shell is fixedly connected to the inner side of the mounting plate. The blocking shell encloses the feeding assembly. The lower end of the blocking shell is fixedly connected to the upper end of the feeding shell. The blocking shell is fixedly connected to the mounting plate by screws.

[0011] As a preferred technical solution, the output shaft of the drive motor is fixedly connected to a drive gear, the outer side of the mounting plate is rotatably connected to a driven gear, the other end of the driven gear passes through the mounting plate and is fixedly connected to a cleaning rod, the outer side of the driven gear is fixedly connected to a drive wheel, the outer side of the mounting plate is rotatably connected to a driven wheel, the drive wheel and the driven wheel are connected to each other by a transmission belt, the driven wheel passes through the mounting plate and is fixedly connected to a conveying auger, and the drive gear and the driven gear are meshed with each other.

[0014] In summary, the present invention has the following main advantages:

[0015] First, the present invention, through the set salvage component, can drive the drive shaft to rotate by starting the drive motor. Under the action of the drive belt, the drive shaft rotates multiple drive wheels. While the drive wheels drive the drive belt to rotate, the filter mesh rotates. The other end of the filter mesh is connected to the bottom of the oxidation ditch body. Thus, under the action of the salvage mesh, large impurities inside the oxidation ditch body can be transported and conveyed, thereby making it easier to clean the impurities inside the oxidation ditch body.

[0016] Secondly, through the feeding assembly, when the retrieval assembly retrieves impurities, the drive motor drives the active gear to rotate, which in turn drives the driven gear. This rotation of the driven gear causes the cleaning rod to rotate, which in turn causes the mounting rod to rotate, thus rotating the cleaning brush. The cleaning brush effectively cleans the surface of the filter mesh, preventing impurities from clogging it during use. The impurities then fall into the inside of the feeding housing. The rotation of the active gear and the drive wheel causes the driven wheel to rotate, which in turn drives the conveying auger. The conveying auger then moves the impurities into the feeding pipe, allowing them to be discharged from the oxidation ditch body through the feeding pipe. Attached Figure Description

The rotation of the drive shaft 32, under the action of the drive belt 34, drives multiple drive wheels 33 to rotate. Simultaneously, the drive wheels 33 drive the drive belt 34, causing the filter mesh 35 to rotate. The other end of the filter mesh 35 is connected to the bottom of the oxidation ditch body 1, thus enabling the transport and conveying of large impurities inside the oxidation ditch body 1, facilitating the cleaning of impurities inside the oxidation ditch body 1. When the retrieval component 3 retrieves impurities, the drive motor 31 drives the drive gear 9 to rotate, which in turn drives the driven gear 10 to rotate, thereby... The driven gear 10 rotates, causing the cleaning rod 41 to rotate. The rotation of the cleaning rod 41 causes the mounting rod 42 to rotate, which in turn drives the cleaning brush 43 to rotate. This allows the cleaning brush 43 to clean the surface of the filter mesh 35, preventing impurities from clogging the filter mesh 35 during use. The impurities then fall into the inside of the discharge housing 44. The drive gear 9 rotates, causing the drive wheel 11 to rotate, which in turn drives the conveying auger 45 to rotate. This allows the conveying auger 45 to move the impurities into the discharge pipe 46, and then discharge the impurities from the oxidation ditch body 1 through the discharge pipe 46. The protective housing 14 protects the drive motor 31, and the heat dissipation mesh 15 provides ventilation and heat dissipation during use.
