Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a cleaning device for a secondary sedimentation tank outlet weir. Background Art

[0002] The utility model relates to the pollution control of domestic wastewater and industrial wastewater. The secondary sedimentation tank is an indispensable part of water treatment. The outlet weir is easily affected by sunlight and water quality, which can breed algae attachments, directly affecting the water quality and visual perception of the outlet water. The secondary sedimentation tank outlet weir is cleaned manually twice a week in summer and once a week in winter. Routine cleaning is required in special circumstances. It is usually arranged in the morning and evening when the temperature is lower. It takes nearly 4 hours for two people to clean at the same time. For safety reasons, they are fully armed and wear high-waisted water pants, life jackets, gloves, etc.

[0003] Problems with manual cleaning:

[0004] 1. Workload: You need to bring two brushes of different materials. Because the moss and algae on the pool wall have strong adhesion, you have to use a homemade wire brush to prime it first and then use a plastic brush to clean it. The workload is large and the operation is complicated.

[0005] 2. Operating environment: The high temperatures in summer are the most unbearable. The stuffiness in water pants makes it easy to get heatstroke and get bit by mosquitoes, and the whole body is soaked after work. The cold winter weather, thick clothing, and difficulty in moving all directly increase the workload of operators.

[0006] 3. Safety: When working in the pool, the soles of your feet may slip when in contact with the moss surface, and the impact of water flow and direct contact with sewage sludge during the scrubbing process may cause personal health and safety issues.

[0007] 4. The cleaning devices available on the market or provided by manufacturers have poor effects, high operating costs, and the center of the weir channel is not standardized and cannot be used directly.

[0008] Daily cleaning is generally done by manual brushing. In order to reduce labor and reduce production safety and occupational health risks, and considering that electric rotary brushes are commonly used on the market, the rotary brush effect is poor and the rotary brush service life is short, a high-pressure water automatic cleaning device is urgently needed. Utility Model Content

[0009] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a cleaning device for the outlet weir of a secondary sedimentation tank. The device is a high-pressure automatic flushing device that uses a U-shaped flushing pipe, a tension spring, a travel guide rail, and a guide wheel. The U-shaped flushing pipe fits the shape of the outlet weir better. The guide wheel ensures that the flushing pipe always maintains a fixed spacing to achieve the flushing force. The tension spring ensures that the cleaning pipe always moves in contact with the inner wall of the outlet weir. The travel guide rail solves the variables generated by the irregular outlet weir in the cleaning pipe, thereby achieving stable cleaning. The utility model solves the problem of incomplete cleaning of irregular surfaces and optimizes the daily management of safe production operations, thereby reducing the labor intensity of employees, avoiding occupational hazards caused by direct contact with sewage, and reducing production and operation costs.
