Description

Technical Field

[0001] The utility model relates to an air extraction micro-flushing toilet system device, which is particularly suitable for toilet systems of decentralized rural residences and belongs to the field of environmental sanitation and water saving. Background Art

[0002] Available water resources are the most important production factor related to the quality of production and life in rural areas, especially in rural areas in the north where seasonal drought is severe. Water conservation and drainage resource reuse are particularly important. Conventional flushing toilets rely entirely on the weight of water to drive the toilet cleaning and the pipe discharge of sanitary waste, so a large amount of flushing water is required. The current toilet water conservation standard in my country is: toilet water consumption ≤5 L / time, squat toilet water consumption ≤6 L / time. According to such flushing water consumption, even the black water output obtained by source separation is too large, resulting in the use of conventional household septic tanks to treat and meet the "Sanitary Requirements for Harmless Treatment of Feces" (GB7959-2012). In addition, due to the low fertilizer efficiency and high cost of cleaning and transportation, farmers are reluctant to use such sewage for fertilization. Utility Model Content

[0003] The purpose of the utility model is to disclose an air extraction micro-flushing toilet system device, which can significantly reduce the water consumption of a single toilet flushing by the user, thereby improving the harmlessness of feces and sewage, and is conducive to the resource recovery and utilization of feces and sewage.

[0004] In order to achieve the above purpose, the utility model scheme is as follows:

[0006] 2. Preferably, an air extractor (5) is vertically installed on the outdoor pipe section of the sewage collection pipe (4); a one-way air valve (6) is provided in the pipe between the air extractor (5) and the septic tank (7);

[0007] 3. Preferably, the outdoor portion of the sewage collection pipe (4) is provided with a hydraulic slope of 2% along the direction of the septic tank (7). Further preferably, the one-way air valve (6) is a horizontally mounted gravity one-way valve.

[0013] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are only used to illustrate the present invention and are not to be regarded as limiting the present invention.

[0014] As shown in the figure, the air-extraction micro-flushing toilet system device comprises an air-extraction micro-flushing toilet (3), a septic tank (7), and a sewage collection pipe (4) connected between the air-extraction micro-flushing toilet (3) and the septic tank (7).

[0015] As shown in the figure, a water tank (1) with an air extraction controller (2) is fixedly installed on the upper end of the air extraction micro-flushing toilet (3); wherein the air extraction micro-flushing toilet, the water tank, and the air extraction controller are installed indoors, and the septic tank is installed outdoors in an underground manner.

[0016] As shown in the figure, the sewage collection pipe connecting the air extraction micro-flushing toilet and the septic tank is arranged according to the requirements of gravity drainage and a hydraulic slope of 2% is set along the direction of the septic tank (7).

[0017] As shown in the figure, an air extractor (5) is vertically installed on the outdoor pipe section of the sewage collection pipe; and a gravity-type one-way air valve is provided at the water outlet of the air extractor.

[0018] As shown in the figure, the septic tank (7) can be connected to multiple air extraction micro-flushing toilets and a corresponding number of air extraction devices through the sewage collection pipe (4) to meet the sanitary drainage needs of multiple toilets in one household.

[0019] In order to further illustrate the structural characteristics and technical effects of the utility model, the necessary technical principle analysis and embodiment effect description of the air extraction micro-flushing toilet system device are respectively made below.

[0020] The working principle of the air extraction micro-flushing toilet system is as follows: turn on the air extraction controller to control the flushing of the water tank, and the air extractor starts synchronously, generating instantaneous suction force in the sewage pipe. At this time, the one-way air valve at the water outlet of the air extractor is closed, and the suction force generated mainly acts on the sewage outlet of the toilet, generating instantaneous suction force on the flushing water and waste, so as to complete the cleaning and sewage discharge of the toilet with a small amount of flushing water; once the feces and sewage enter the sewage collection pipe, the air extractor stops running immediately. At this time, the one-way air valve at the end is freely opened outward by the gravity flow of feces and sewage. Therefore, the wastewater and waste can flow to the septic tank along the sewage pipe with a certain hydraulic slope (usually >1%) at an initial velocity of up to 10m / s, thereby completing the pipeline sewage discharge.

[0021] Effect statement of the embodiment: Based on the application test of this embodiment, the water consumption of a single flushing toilet system device is ≤1.5L / time. 3 For a standard facultative anaerobic fermentation three-stage septic tank, the effective volume of the first two tanks is 1000L. Taking the volume of each adult defecation as 0.3L, according to the minimum hydraulic retention time of 30d, the air extraction micro-flushing toilet system can accommodate 556 toilet usages per month, which is enough to meet the toilet needs of ordinary families. The reduced feces and sewage are fully fermented and harmlessly treated after a longer retention time (≥30 days) in the septic tank, which is conducive to rural residents returning the fertilizer and water resources in the third stage of the septic tank that meet the harmless sanitation requirements to the fields.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
