[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figure 1-Figure 3 The utility model provides a mud-water separation device for sewage treatment, including a sedimentation tank 1, a guide rod 2 is fixedly installed in the sedimentation tank 1, an upper floating arc plate 3 is sleeved and installed on the guide rod 2, the lower part of the upper floating arc plate 3 is a sinking counterweight arc plate 4, the upper floating arc plate 3 and the sinking counterweight arc plate 4 are surrounded to form a hollow tube structure, the upper floating arc plate 3 is connected and inserted with a suction pipe 5, the tops of all the suction pipes 5 are connected and provided with a confluence pipe 6, the top of the confluence pipe 6 is provided with a guide pipe, the guide pipe is connected to an installation hose 7, and a pump 8 is installed on the hose 7.

[0027] Specifically, Figure 1 As shown, the arc of the upper floating arc plate 3 is greater than 180 degrees, which prevents the upper floating arc plate 3 from sinking completely due to the excessive volume of the sinking counterweight arc plate 4.

[0028] Specifically, Figure 2 As shown, the water suction pipe 5 is arranged in the middle position of the upper floating arc plate 3 to keep the upper floating arc plate 3 stable.

[0029] Specifically, Figure 3 As shown, the guide rod 2 is installed on the outermost floating arc plate 3 and the sinking counterweight arc plate 4.

[0030] Specifically, Figure 1 As shown, a filter screen 9 is provided at the end of the water suction pipe 5, and a distance is left between the filter screen 9 and the sinking counterweight arc plate 4, which has a filtering effect.

[0031] Specifically, the top of the guide rod 2 is arranged flush with the top of the sedimentation tank 1 to prevent the floating arc plate 3 from being separated from the guide rod 2.

[0032] Working principle:

[0033] When in use, align the combination of the floating arc plate 3 with the guide rod 2 and place it, and the mud and water in the sedimentation tank 1 are stratified. At this time, the sinking counterweight arc plate 4 brings the floating arc plate 3 down, and the floating arc plate 3 partially sinks and floats on the water surface. The liquid surface submerges the filter screen 9, and the pump 8 works. Water enters the inner cavity of the floating arc plate 3 and the sinking counterweight arc plate 4, enters the water suction pipe 5, enters the inlet pipe 6, enters the hose 7, and is pumped out. The floating arc plate 3 floats and sinks as the liquid level drops until the sinking counterweight arc plate 4 sinks to the mud layer.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
