Problems solved by technology

The bottom of the sedimentation ditch has been settled for a long time, and it is necessary to scrape the sediment at the bottom regularly, scrape it into the sedimentation ditch, and then pump it out through the sludge pump. However, the traditional scraping mechanism often scrapes the water at the bottom of the pool during the scraping process. It has a disturbing effect and affects the sedimentation effect of the pool

Embodiment Construction

[0057] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples or drawings are used to illustrate the present invention, but not to limit the scope of the present invention.

[0058] Such as Figure 14 , 15 As shown, it includes the following steps:

[0059] (1) scraping:

[0060] Such as Figure 15 As shown in b, 1) The driving mechanism 4 is controlled by the motor 1, and the driving mechanism 4 controls the scraping unit 3 installed in the sedimentation ditch 2, such as Figure 15 As shown in c, all the support plates 44 in the scraping unit 3 swing down;

[0061] Such as Figure 14 As shown in a, 2) The motor 1 controls the driving mechanism 4, and the driving mechanism 4 controls the scraping unit 3 installed in the sedimentation ditch 2 to scrape forward toward the sedimentation pit 6 in the sedimentation ditch 2; The sediment on the...

Abstract

The invention belongs to the technical field of sediment scraping, and in particular relates to a sediment scraping method for sewage treatment, which includes the following steps: (1) scraping: (2) reset: during the working process, the above two steps of scraping and reset are operated alternately , the sediment in the sedimentation tank is intermittently pushed forward, and finally collected into the sedimentation pit in the sedimentation tank; the scraping mechanism designed in the present invention has an arc-shaped support plate and a scraper, and the same scraping unit The upper ends of the two scrapers in the middle are smooth transitions before or after the upper swing, and the sewage on the upper side flows smoothly through the transition arc surface formed by the two scraper plates. The scraper mechanism designed in the present invention A stabilizing plate is also designed. During the reset process of the scraping unit, the sewage in the sedimentation ditch will flow smoothly from the lower side of the two stabilizing plates in the scraping unit. The degree of disturbance to the sewage in the sedimentation ditch during the front scraping or reset process.

Description

[0001] Technical field [0002] The invention belongs to the technical field of sediment scraping, and in particular relates to a sewage treatment sediment scraping mechanism and a method thereof. Background technique [0003] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. Various fields are also increasingly entering the daily life of ordinary people. [0004] Sedimentation ditch is a structure that uses sedimentation to remove suspended solids in sewage. Sedimentation trenches are widely used in wastewater treatment. The bottom of the sedimentation ditch has been settled for a long time, and it is necessary to scrape the sediment at the bottom regularly, scrape it into the sedimentation ditch, and t...
