Problems solved by technology
[0002] Due to the relatively deep depth of the traditional sedimentation tank, the sludge in the sewage interacts with the sewage water body for a relatively long time before falling into the bottom of the tank, which will cause the sediment to settle to the bottom of the tank It was mixed into the sewage water body again by the excessive impact of the sewage water body before, resulting in low sedimentation efficiency of the sediment in the sewage water

Embodiment Construction
[0038] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0039] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The invention relates to a sedimentation tank and a sewage treatment device. The sedimentation tank comprises a tank body, a plurality of sedimentation pieces and a sludge discharge pipe, the tank body is used for accommodating sewage; the plurality of sedimentation pieces are arranged in the tank body along the depth direction of the tank body and are used for dividing the internal space of the tank body into a plurality of water passing spaces; the plurality of sedimentation pieces jointly form an integral sedimentation assembly; the sedimentation pieces can rotate between a first position and a second position; when the sedimentation pieces are positioned at the first position, the inclination angle of the sedimentation pieces relative to the tank body is marked as a first angle, so that sedimentation mud in the sewage is settled to the sedimentation pieces when the sewage flows through the water passing spaces; when the sedimentation pieces are located at the second position, the inclination angle of the sedimentation pieces relative to the tank body is marked as a second angle, and the second angle is larger than the first angle, so that the sedimentation mud is separated fromthe sedimentation pieces by virtue of gravity and falls into the bottom of the tank body; the sludge discharge pipe is arranged at the bottom of the tank body and is used for discharging deposited sludge settled to the bottom of the tank body out of the tank body by virtue of negative pressure.
Description
technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a sedimentation tank and a sewage treatment device. Background technique [0002] Due to the relatively deep depth of the traditional sedimentation tank, the sludge in the sewage interacts with the sewage water body for a relatively long time before falling into the bottom of the tank, which will cause the sediment to settle to the bottom of the tank It was mixed into the sewage water body again by the excessive impact of the sewage water body before, resulting in low sedimentation efficiency of the sediment in the sewage water. Contents of the invention [0003] Based on this, it is necessary to provide a sedimentation tank and a sewage treatment device capable of improving the sedimentation efficiency of sediment in sewage. [0004] A sedimentation tank comprising: [0005] The pool body is used to contain sewage; [0006] A plurality of sediment...
