Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a device for centralized treatment and recycling of rural domestic sewage. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people.

[0003] At present, domestic sewage in rural residents' daily life is generally discharged directly into the sewer. However, in addition to washing clothes and washing up, the kitchen will also produce a large amount of wastewater. In particular, the kitchen water will produce a large amount of food debris. If it is not handled properly, it is easy to be discharged directly into the sewage discharge pipe. This makes the sewage discharge pipe prone to blockage, and the sewage discharge pipe that has been used for such a long time will produce dirt accumulation, which reduces the water flow area of ​​the sewage pipe. As a result, after the kitchen discharges a large amount of sewage into the sewage pipe in a short period of time, it is easy for sewage to overflow the sewage discharge pipe, causing odor in the kitchen and the need to clean up the overflowed sewage.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0021] Please refer to 1-2, a rural domestic sewage centralized treatment and recycling device, including: an inlet pipe 1, the inlet pipe 1 is connected to a connecting pipe 3 and an anti-overflow tank 5 through an inclined tee pipe 2, the connection point between the inclined tee pipe 2 and the anti-overflow tank 5 is higher than the connection point between the inlet pipe 1 and the inclined tee pipe 2, the lower end of the connecting pipe 3 is connected to the anti-overflow tank 5, and a plurality of filter discs 9 are slidably arranged in the anti-overflow tank 5.

[0022] Specifically, the anti-overflow tank 5 is located below the ground surface, and a convex ridge is welded on the filter disc 9, which is slidably connected to a slide groove provided on the anti-overflow tank 5. By arranging multiple filter discs 9, when there are too many impurities in the filter disc 9 located on the uppermost side, the multiple filter discs 9 can be moved upward as a whole, so that the filter disc 9 located on the lower side can filter the sewage, thereby extending the time interval for cleaning the filter disc 9 and reducing the maintenance cost. The lower end of the anti-overflow tank 5 is connected with a water outlet pipe 10. The utility model arranges an inclined three-way pipe 2. When the water flow is greater than the bearing range of the connecting pipe 3, the excess sewage is introduced into the anti-overflow tank 5 through the inclined three-way pipe 2, thereby avoiding the sewage overflowing from the water inlet pipe 1. The filter disc 9 is arranged in the anti-overflow tank 5 to filter the sewage passing through the anti-overflow tank 5, reduce the amount of residue entering the sewage pipe, reduce the condensation speed of the dirt on the inner wall of the pipe, thereby improving the service life of the sewage pipe.

[0023] Furthermore, multiple filter plates 9 are connected together through a threaded screw 6, one end of which is spirally connected to a screw sleeve 7, which is connected to the anti-overflow water tank 5 through a bearing 8. The screw sleeve 7 is fixedly connected to the inner ring of the bearing 8, and the outer ring of the bearing 8 is embedded in the inner wall of the anti-overflow water tank 5.

[0024] Specifically, by rotating the screw sleeve 7, the screw sleeve 7 rotates in place in the anti-overflow tank 5, and the threaded screw 6 slides up and down in the screw sleeve 7, and then drives the filter plate 9 to slide up and down. On the one hand, multiple filter plates 9 can be switched to filter sewage, and on the other hand, the overflowed sewage can be multiple filtered, that is, the impurities and sludge brought out by the overflowing sewage can be filtered.

[0025] Furthermore, the connecting pipe 3 is connected to the anti-overflow tank 5 through the elbow 4 , and the connection point between the elbow 4 and the anti-overflow tank 5 is located at the upper end of the filter disc 9 .

[0026] Specifically, the axial direction of the inclined tube of the inclined tee 2 is inclined upward, so that the connecting position between the inclined tube of the inclined tee 2 and the anti-overflow tank 5 is higher than the water inlet of the inclined tube of the inclined tee 2, thereby preventing sewage from directly flowing into the anti-overflow tank 5, reducing the use frequency of the anti-overflow tank 5, and then reducing the condensation amount of dirt on the inner wall of the anti-overflow tank 5, ensuring the normal operation of the anti-overflow tank 5, when the dirt on the inner wall of the connecting pipe 3 is sufficiently condensed, the water flow area of ​​the connecting pipe 3 is reduced, and the sewage entering the connecting pipe 3 cannot pass quickly, but stagnates in the pipe, and even sewage overflows. At this time, the sewage enters the anti-overflow tank 5 through the inclined tee 2, thereby preventing sewage overflow.

[0027] Furthermore, a scraper blade 91 is provided at the edge of the filter disc 9 , and the scraper blade 91 is closely attached to the inner wall of the anti-overflow water tank 5 .

[0028] Specifically, by fixing a scraper blade 91 around the edge of the filter disc 9, when the filter disc 9 is driven by the threaded screw 6 to slide in the anti-overflow tank 5, the scraper blade 91 scrapes off the condensed dirt on the inner wall of the anti-overflow tank 5 to ensure the normal operation of the sewage pipe.

[0029] Furthermore, an anti-slip sleeve 71 is fixedly sleeved on the outer side of one end of the screw sleeve 7 located outside the anti-overflow tank 5 .

[0030] Specifically, by fixing the anti-slip sleeve 71 on the periphery of the screw sleeve 7, it is convenient for residents to twist the screw sleeve 7 to make some adjustments to the filter plate 9, such as adjusting the positions of multiple filter plates 9 and cleaning the dirt on the inner wall of the anti-overflow water tank 5 by moving the filter plates 9.

[0031] In this utility model, reference is made to Figure 1 The amount of rural sewage is smaller than that of urban sewage, so the sewage treatment technology and process used are different from those in cities. The general process is: first, sewage is discharged from residents' homes through sewage pipes to the transfer tank, and after coarse filtration, it enters the regulating tank and is pumped into the integrated sewage treatment equipment through a water pump, and then undergoes desalination treatment, aerobic treatment, anaerobic treatment, fine filtration treatment, sedimentation treatment, and ultraviolet disinfection treatment in turn; thereby achieving the recycling of sewage. Only a brief introduction is given here, and the specific implementation methods and technical principles are common knowledge known to staff in this field, and will not be explained in detail here.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
