Instruction Manual

A central rotating scraper-suction sludge removal machine for wastewater treatment

Technical Field

This utility model relates to the field of wastewater treatment equipment technology, specifically a central-rotating scraper and sludge suction machine for wastewater treatment.

Background Technology

In existing wastewater treatment technologies,刮吸泥机 is commonly used, with the most prevalent being the central-rotating type. The working principle of the current central-rotating刮吸泥机 involves using a central rotation to drive a scraper at the bottom of the sedimentation tank to agitate settled sludge, and then using a sludge pump to absorb the sludge.

The sump pumps mentioned above are mostly installed underwater, thus the selection of various sump pumps must consider waterproofing factors, which undoubtedly increases costs. Additionally, the existing central-rotating sludge scraper only performs sludge removal from the bottom walls of the sedimentation tank, failing to address deposits and pollutants on the side walls. Furthermore, the current sludge scrapers, particularly in terms of the setup of the sludge intake pipes, utilize more laid-out piping, which also adds to the cost.

Novel Utility Content

The purpose of this utility model is to provide a central-rotating sludge scraper for wastewater treatment, which features simultaneous scraping and suction of sludge from both the bottom and side walls, and the advantage of lowering the cost of the sludge pump by setting it above the water level. It addresses the existing issue of sludge scraper pumps requiring waterproofing and only scraping the bottom wall of the sedimentation tank.

To achieve the aforementioned objectives, the present utility model provides the following technical solution: A central rotation scraper-suction sludge removal machine for wastewater treatment, comprising a sedimentation tank body, a bridge frame, a sludge pump, side wall scrapers, a central vertical stand, and a bottom wall scraper. The bottom of the central vertical stand is fixed at the center of the bottom of the sedimentation tank body. The top of the central vertical stand is fixed with an electric motor sleeve, within which is mounted the driving motor. The upper end of the driving motor is rotatably connected to a central turning stand, which is welded and fixed to the bottom center of the bridge frame. The sludge pump is fixed on the upper surface of the bridge frame. The bridge frame and the bottom wall scraper are fixedly connected through a connecting vertical frame. The upper end of the side wall scraper is fixed to the bridge frame by a mounting frame, and the bottom end of the side wall scraper is fixedly connected to the two ends of the bottom wall scraper. The side wall scraper and the bottom wall scraper have the same structure, both internally hollowed. Both the side wall scraper and the side opposite the sedimentation tank body side are connected to suction branch pipes, which are connected to the main suction pipe. The bottom wall scraper is connected to the bottom of the main suction pipe, which is connected to the sludge pump. A mud outlet pipe is connected to the sludge pump. On the side of the side wall scraper and the bottom wall scraper adjacent to the inner wall of the sedimentation tank body, scraper blades are installed, and at least three suction nozzles are provided on the side of both the side wall scraper and the bottom wall scraper adjacent to the inner wall of the sedimentation tank body.

Preferred, the main cross-section of the sedimentation pond is circular.

Preferred, the vertical height of the bridge is higher than the upper surface of the sedimentation tank's main body.

Preferred, there are two mud-pumps in total, and the mud-pumps are symmetrically distributed around the bridge frame.

Preferred are scraper blades that contact both the inner wall of the sedimentation pool's main body and are made of hard plastic material.

Preferred, the side wall scraper cross-section is curved, and the curvature of the side wall scraper cross-section is consistent with the curvature of the sedimentation tank main cross-section, with the bottom wall scraper in a long strip shape.

Compared to existing technology, the beneficial effects of this utility model are as follows:

1. This utility model primarily targets circular sedimentation tanks, utilizing bridge structures as carriers. It employs a drive motor to synchronize the rotation of the bridge, side wall scrapers, and bottom wall scrapers, thereby achieving centralized sludge removal. Additionally, the side wall scrapers can perform sludge scraping on the tank's sides, offering a broader scraping range compared to traditional sludge removal and suction machines.

2. The side wall scraper and bottom wall scraper of this utility model are both hollowed out, and suction mud nozzles are provided on both the side wall scraper and bottom wall scraper. The mud scraped is then吸附 by the suction force of the mud pump from the nozzles to the cavity, and then to the mud branch pipe and main pipe, ultimately being discharged out of the pool through the set mud outlet pipe. This design allows the mud pump to be fixed on the bridge架, significantly reducing the requirements for waterproofing of the mud pump and the electrical transmission lines on it, which helps to save costs.

3. This utility model has a higher cost-performance ratio and more comprehensive functions compared to the existing central-rotary sludge scraper and suction machine. It is not only suitable for scraping and suctioning sludge during sedimentation but also for cleaning the sedimentation pond afterward.
