DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment: A sewage treatment device for construction engineering, such as Figure 1-Figure 4 As shown, it includes a tank body 1, a water inlet pipe 2, a water outlet pipe 3 and a supporting leg 4. The water inlet pipe 2 adapted to be connected to the sewage transmission pipe is installed at the center of the top surface of the tank body 1 by bolts, and the water outlet pipe 3 is connected to the eccentric part of the lower part of the tank body 1 by bolts. Five supporting legs 4 are installed along the circumferential direction by bolts at the lower part of the tank body 1, and it also includes a filter plate 6 and a rebound spring 7. A sewage discharge hole 5 is opened in the middle part of the tank body 1 along the circumferential direction. A filter plate 6 that can slide up and down along its inner wall is provided in the tank body 1. The filter plate 6 is arranged in a truncated cone shape. When the filter plate 6 moves downward, it will be flush with the sewage discharge hole 5. A rebound spring 7 is provided between the connection between the filter plate 6 and the inner wall of the tank body 1.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a stepper motor 8, a threaded rod 9, a guide rod 10 and a baffle 11. The stepper motor 8 is installed on the left side of the middle of the tank body 1 by bolts, and the threaded rod 9 connected to the output shaft of the stepper motor 8 through a coupling is rotatably installed on the left side of the middle of the tank body 1. The guide rod 10 is installed on the right side of the middle of the tank body 1 by bolts. The threaded rod 9 is threadedly connected with a baffle 11 that can slide up and down along the guide rod 10. When the baffle 11 moves, it will block the sewage hole 5, thereby preventing sewage from overflowing from the sewage hole 5.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, a collecting basket 12 is also included. The lower part of the outer wall of the tank body 1 is fixedly installed with the collecting basket 12 along the circumferential direction. The collecting basket 12 is located below the drain hole 5. The collecting basket 12 will receive the debris dropped from the drain hole 5.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, a vibrator 13 is also included. The vibrator 13 is installed at the center of the filter plate 6 through bolts. The vibrator 13 will cause the filter plate 6 to vibrate.

[0025] like Figure 1 , Figure 3 and Figure 4As shown, it also includes observation windows 14. Three observation windows 14 made of transparent material are installed on the upper part of the tank body 1 along the circumferential direction by bolts. The observation windows 14 will facilitate observation of the situation inside the tank body 1.

[0026] In the initial state, the baffle 11 is in a state of blocking the drainage hole 5. When it is necessary to process the sewage in the construction project, the sewage pipe is first connected to the water inlet pipe 2, and then the vibrator 13 is started. The vibrator 13 will vibrate the filter plate 6, and then the sewage in the construction project is injected into the tank body 1 from the water inlet pipe 2 through the sewage pipe. The filter plate 6 will filter and screen the debris in the sewage. The debris remaining on the filter plate 6 will be dispersed along the inclined surface of the truncated cone toward the inner wall of the tank body 1 as the filter plate 6 shakes, so that the middle part of the filter plate 6 is always kept in a smooth state, thereby preventing the debris from clogging the filter plate 6 and affecting the filtration efficiency of the sewage. At the same time, as the filter plate 6 The accumulation of debris will push the filter plate 6 to move downward along the inner wall of the tank body 1, and the return spring 7 will be compressed. When the filter plate 6 is observed to move to the drain hole 5 through the observation window 14, the stepper motor 8 is started, and the output shaft of the stepper motor 8 will drive the threaded rod 9 to rotate. The threaded rod 9 will drive the baffle 11 to move upward along the guide rod 10 through the thread, thereby opening the drain hole 5, so that the debris remaining on the filter plate 6 can slide out of the tank body 1 from the drain hole 5, and the collection basket 12 will receive and collect the debris dropped from the drain hole 5, thereby reducing the difficulty of manual cleaning in the later stage. When the sewage treatment is completed, the collection basket 12 can be cleaned.
