DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figure 1 to Figure 2 As shown, a combined septic tank includes a primary corruption tank 1, a deep corruption tank 2 and a clarification tank 3 which are arranged from left to right in sequence. The tops of the primary corruption tank 1, the deep corruption tank 2 and the clarification tank 3 are all provided with cleaning ports 4, and sealing covers are provided at the cleaning ports. Positioning rings 5 ​​are provided on the upper and lower parts of the outer sides of the primary corruption tank 1, the deep corruption tank 2 and the clarification tank 3.

[0019] The positioning ring 5 facilitates the positioning and fixing of the primary corruption tank 1 , the deep corruption tank 2 and the clarification tank 3 .

[0020] A manure inlet pipe 6 is provided on the top of the primary decomposition tank 1, and a manure passing pipe 7 is detachably connected to the deep decomposition tank 2 on one side. A manure passing pipe 2 15 is detachably connected to the side of the deep decomposition tank 2 and the clarification tank 3. An exhaust pipe 16 is provided on the top of the clarification tank 3, and a drainage pipe 17 is provided on the upper part of one end. Flanges are provided at both ends of the manure passing pipe 7, and a plurality of mounting holes for mounting bolts are provided on the flanges. The designs of the manure passing pipe 2 15 and the manure passing pipe 7 are the same.

[0021] By providing the manure pipe 1 7 and the manure pipe 2 15 , the primary decomposition tank 1 , the deep decomposition tank 2 and the clarification tank 3 can be connected.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, a reduction motor 8 is installed on one side of the primary decomposition tank 1, and a stirring shaft 9 extending to the inside of the primary decomposition tank 1 is installed on the output shaft of the reduction motor 8, and a plurality of stirring blades 10 are installed on the stirring shaft 9. A filter screen 12 is installed at the connection between the manure pipe 7 and the inside of the primary decomposition tank 1. The filter screen 12 is a semicircular structure, and a U-shaped positioning frame 11 is provided on the outside of the filter screen 12 inside the primary decomposition tank 1. One end of the stirring shaft 9 passes through and is rotatably connected to the positioning frame 11, and the end of the stirring shaft 9 is connected to a scraper 14 adapted to the filter screen 12 through a connecting rod 13.

[0023] The design of the filter 12 can prevent debris from entering the manure pipe 7, prevent the manure pipe 7 from being blocked, and ensure the normal operation of the septic tank. The reduction motor 8 drives the stirring blade 10 to rotate through the stirring shaft 9, which can evenly mix the manure newly entering the primary decomposition tank 1 with the manure that has entered the primary decomposition tank 1 for a period of time, so that the newly entered manure can quickly and comprehensively contact the anaerobic bacteria, which can accelerate anaerobic fermentation and improve the processing efficiency. The stirring shaft 9 drives the scraper 14 to rotate through the connecting rod 13, which can scrape off the debris blocked in the filter hole, further ensuring the smoothness of the manure pipe 7.

[0024] In specific use, the positioning ring 5 is used to facilitate the positioning and fixing of the primary decomposition tank 1, the deep decomposition tank 2 and the clarification tank 3. The filter screen 12 can prevent debris from entering the manure pipe 7 to avoid blockage of the manure pipe 7. The reduction motor 8 drives the stirring blade 10 and the scraper 14 to rotate. Through stirring, the newly entered manure can quickly and comprehensively contact the anaerobic bacteria, which can accelerate anaerobic fermentation and improve the processing efficiency. The rotation of the scraper 14 can scrape off the debris blocked in the filter hole to ensure the smooth passage of the manure pipe 7.
