Problems solved by technology

The bottom of the sedimentation tank has been settled for a long time, and it is necessary to scrape the sediment at the bottom regularly, scrape it to the sedimentation ditch, and then pump it out through the sludge pump, but 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 particularly relates to a sewage treatment sediment scraping method which comprises the following steps: (1) scraping: and (2) resetting. In the working process, the scraping step and the resetting step are alternately performed, and sediments in a sedimentation tank are intermittently pushed forwards and finally collected intoa sedimentation pit in the sedimentation tank. According to a scraping mechanism designed by the invention, supporting plates and scraping plates are designed to be arc-shaped, the upper ends of thetwo scraping plates in the same scraping unit are in smooth transition before or after swinging upwards, and sewage at the upper side part stably flows through a transition arc-shaped surface formed by the two scraping plates. The scraping mechanism is further provided with flow stabilizing plates, sewage on the lower side in the sedimentation tank can stably flow through the lower sides of the two flow stabilizing plates in the scraping units in the resetting process of the scraping units, and the disturbance degree of the scraping mechanism on the sewage in the sedimentation tank in the forward scraping or resetting process is reduced.

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 tank is a structure that uses sedimentation to remove suspended solids in sewage. Sedimentation tanks are widely used in wastewater treatment. The bottom of the sedimentation tank has been settled for a long time, and it is necessary to scrape the sediment at the bottom regularly, scrape it to the sedimentation ditch, and then pum...
