Problems solved by technology

[0002] The main pollutants contained in hospital sewage are: pathogens (parasitic eggs, pathogenic bacteria, viruses, etc.), organic matter, floating and suspended matter, radioactive pollutants, etc. In order to improve the quality of sewage discharge, floating matter on sewage is usually In the prior art, the sewage is thrown out by centrifugation, so that the floating matter remains in the centrifuge bucket, so as to realize the separation of the sewage and the floating matter, but the centrifugal force in the centrifuge bucket is easy to form a vortex, so that it is affected by the vortex to float It is difficult to concentrate the contents in the centrifuge bucket, and it is difficult to clean up later;
[0003] Or, the floating matter is easily thrown out together with the sewage due to the centrifugal force, which will not achieve a good separation effect and reduce the quality of sewage treatment

Embodiment 1

[0043] see figure 1 and figure 2 As shown, the purpose of this embodiment is to provide a medical sewage treatment device based on centrifugal separation of floating objects, including an external mechanism 100 and an internal mechanism 200, the external mechanism 100 includes an outer casing 110, and the internal mechanism 200 is arranged on the outer casing 110 inside, and rotate inside it to generate centrifugal force, see image 3 As shown, the internal mechanism 200 includes an inner housing 210 and a separation assembly 220, and the separation assembly 220 is disposed in the inner housing 210, wherein:

[0044] The tops of the outer shell 110 and the inner shell 210 are both open, the main purpose of which is to facilitate the injection of sewage into the inner shell 210;

[0045] The separation assembly 220 includes an inner column 221, which runs through the top wall of the inner housing 210 and is fixedly connected to the center of the bottom wall of the outer hous...

Embodiment 2

[0051] Considering the effect of centrifugal force, if the way of separating from the outside is adopted, the floating object may break through the separated filter screen 2233 under the action of centrifugal force. For this, please refer to Figure 5 As shown, the collector 223 includes a right-angle plate 2231 and an isolation block 2232, the isolation block 2232 is arranged in the opening of the right-angle plate 2231, and side plates 2234 are arranged on both sides of the right-angle plate 2231, wherein:

[0052] An inlet chamber 223D and a collection chamber 223C are formed between the isolation block 2232 and the right-angle plate 2231. The inlet chamber 223D is located on the top of the isolation block 2232, the collection chamber 223C is located on one side of the isolation block 2232, and the bottom of the collection chamber 223C is provided with a filter screen 2233.

[0053] working principle:

[0054] The right-angle plate 2231 in this embodiment makes the outer si...

Embodiment 3

[0059] In order to scrape the floating matter on the inner wall of the inner housing 210, please refer to Figure 7 As shown, the collecting piece 223 is provided with an outer cover 224, and the outer cover 224 is a "U"-shaped structure. The outer surface is made of rubber structure, which can scrape the floating objects attached to the inner wall of the inner housing 210 after being bonded to the inner wall of the inner housing 210 .

[0060] In addition, a circulation cavity 2241 is opened in the outer cover 224 near the sinking surface 223A, and its main purpose is to provide a drainage channel for the sewage flowing out of the sinking surface 223A.

Abstract

The invention relates to a sewage treatment device, in particular to a medical sewage treatment device for separating floating objects based on a centrifugal type. It includes an external mechanism including an outer casing, the internal mechanism is arranged in the outer casing, and an internal mechanism including an inner casing and a separate assembly. In the present invention, through the interference of the separation plate, the sewage in the inner casing cannot form a vortex, thereby reducing the impact of the vortex on the floating matter, and the reduced floating matter will be attached to the filter surface, and then subjected to the centrifugal force. The floating matter attached to the filter surface moves to the eccentric place and enters the collecting part corresponding to the moving direction, and then after reducing the vortex, the filter surface cooperates with the centrifugal force to realize the collection of floating objects, which eliminates the interference of the vortex and facilitates The treatment of floating objects in the later stage.
