Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 and 2, as a preferred embodiment of the present utility model, the present embodiment provides a medical wastewater and sewage treatment tank, including a tank body 1, a cover plate 3 is disposed on the top of the tank body 1, a motor 4 is fixedly mounted on the cover plate 3, the motor 4 is connected with a stirring shaft 5, and the stirring shaft 5 is located in the tank body 1;
the bottom of the tank body 1 is also provided with a flow dividing cone 7, the flow dividing cone 7 is positioned in the center of the tank body 1, and the flow dividing cone 7 is used for guiding liquid flowing from the upper part to the lower part of the tank body 1 to flow towards the periphery of the tank body 1;
the periphery of the bottom of the tank body 1 is also provided with a drainage ring 8, the bottom of the drainage ring 8 is connected with the flow dividing cone 7, and the drainage ring 8 is used for guiding the liquid guided by the flow dividing cone 7 to flow upwards of the tank body 1;
the middle inner wall of the tank body 1 is connected with an interception net 9, the interception net 9 is used for intercepting suspended matters in liquid which flows upwards and is drained by the drainage ring 8, and the interception net 9 can be made of nonwoven geotextile.
Specifically, the tank body 1 is a circular tank body, and the interception net 9 is in a circular ring shape.
In this embodiment, by setting the tank body 1 to be a circular tank body, and setting the interception net 9 to be a circular ring, the main purpose is to reduce the power loss along the flow path of sewage in the tank body 1 and reduce the power consumption of the electrode.
Specifically, the interception net 9 forms an acute angle of 20-70 degrees with the inner wall of the tank body 1.
In this embodiment, considering that when sewage flows from bottom to top, the sewage is prevented from flowing transversely on the bottom surface of the interception net 9, so that flocculent suspended matter intercepted by the interception net 9 flows into the openings of the interception net 9 again, the embodiment forms an acute angle of 20-70 degrees, preferably an acute angle of 35-50 degrees, with the inner wall of the tank body 1, so that the intercepted suspended matter can be effectively prevented from flowing again, and the angle is not too small, and too small can cause a larger pressure to be formed at the position, so that flocculent can pass through the meshes of the interception net 9, and the interception efficiency is affected; in addition, after the arrangement, sewage at the upper part of the interception net 9 can flow downwards from the middle part of the interception net 9, and the power consumption of the electrode is reduced.
