That is, by pouring water into the siphon bucket and using a dry sewage pump to partially discharge the sewage in the siphon bucket to generate negative pressure in the bucket, the negative pressure siphons the lower sewage in the well into the bucket, and then the dry sewage pump discharges it to the municipal pipe network or the terminal sewage treatment facility. Dry sewage pump siphon drainage mainly solves the problem of lifting low sewage level in a single well (pool) at a short distance, and cannot achieve multi-point and long-distance drainage.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and shown in the accompanying drawings here can be arranged and designed in various different configurations.
[0028] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0029] Please refer to Figures 1-4As shown in the figure, an embodiment of the present application provides a negative pressure siphon drainage system, including at least one negative pressure siphon well 1 for connecting to a domestic sewage source. Each negative pressure siphon well 1 is simultaneously connected to a negative pressure siphon tank 4 through a connecting pipeline. The negative pressure siphon tank 4 is configured with a vacuum pumping device, which is used to form a negative pressure in the negative pressure siphon tank 4 and / or the connecting pipeline, and the negative pressure siphon tank 4 is also configured with a drainage pipeline.
[0030] Among them, the negative pressure siphon well 1 can be used as an initial collection point distributed near at least one farmer household. One or more of them can be set. When multiple are set, they can form a collection network, enabling the layout of initial collection points in a larger area. The connecting pipeline connects each negative pressure siphon well 1 to the negative pressure siphon tank 4 simultaneously, so that the sewage collected at each initial collection point can be converged into the negative pressure siphon tank 4 for collection and then discharged to the municipal pipe network or the terminal sewage treatment system. Since the negative pressure siphon tank 4 is configured with a vacuum pumping device, the vacuum pumping device can form a high negative pressure in the negative pressure siphon tank 4 and the connecting pipeline. In this way, the sewage from each negative pressure siphon well 1 can be sucked into the negative pressure siphon tank 4 under the siphon action formed by the negative pressure, thereby realizing long-distance and multi-point siphon drainage.
[0031] Through the above technical solution, the cooperation of the negative pressure siphon tank 4 and the vacuum pumping device can make the connecting pipeline and the negative pressure siphon well 1 connected to it generate a high negative pressure, siphon the sewage in the numerous negative pressure siphon wells 1 connected to the negative pressure siphon tank 4 into the connecting pipeline and the negative pressure siphon tank 4, and finally discharge it through the drainage pipeline, thereby realizing the collection and drainage of sewage over a long distance and at multiple points.
[0032] In one embodiment, the connecting pipeline is connected to the negative pressure siphon well 1 through a drainage valve 2, and the drainage valve 2 is used to connect the negative pressure adsorption well to the connecting pipeline when the liquid level in the negative pressure siphon well 1 is higher than a preset liquid level, and disconnect the negative pressure adsorption well from the connecting pipeline when the liquid level in the negative pressure siphon well 1 is lower than the preset liquid level.
[0033] In this way, the negative pressure siphon well 1 can be opened high and stopped low through the drainage valve 2 that can drain water according to the liquid level situation, that is, it automatically opens at high liquid level, and the sewage in the well is quickly siphoned into the negative pressure siphon pipe network 3 and the negative pressure siphon tank 4 formed by the connecting pipeline. It automatically closes at low liquid level to ensure the airtightness of the entire negative pressure siphon pipe network 3, and the water suction port always remains below the liquid level during the water conveyance process, and no air enters the negative pressure siphon pipe network 3.
[0034] Preferably, the drainage valve 2 can be a float level switch, so that it can be automatically opened and closed according to the liquid level situation.
[0035] In order to improve the integrity of the pipe network formed by the connecting pipelines and the convenience of siphoning, further, the connecting pipelines include at least one main connecting pipe and at least one connecting branch pipe communicating with the main connecting pipe, and the connecting branch pipe and the main connecting pipe jointly form a negative pressure siphon pipe network 3 at least for laying in long-distance scenarios. With such a structure, it is convenient to form a divergent structure similar to a tree shape, and through such a structure, when the negative pressure siphon drainage system is operating, in the closed working condition of the negative pressure siphon pipe network 3, the inside is in a negative pressure state, the sewage in the pipeline is in a full-pipe static state, and once the siphon drainage valve 2 in the negative pressure siphon well 1 is opened, the sewage in the pipe network starts to quickly flow into the negative pressure siphon tank 4 under the action of negative pressure siphon, and the siphon effect is better.
[0036] Furthermore, the vacuum pumping device may include at least one vacuum pump 5, and the vacuum pump 5 communicates with the upper end of the negative pressure siphon tank 4. Two vacuum pumps 5 may also be provided in parallel, so that when one of the vacuum pumps 5 fails, the other can work normally.
[0037] In the specific implementation process, the drainage pipeline includes at least one sewage pump 6, the input end of the sewage pump 6 communicates with the bottom of the negative pressure siphon tank 4, and the output end of the sewage pipe is used to connect to the terminal treatment system or the municipal pipe network. The sewage pump 6 adopts a dry sewage pump 6, which can timely discharge the sewage after the domestic sewage is siphoned into the negative pressure siphon tank 4.
[0038] In the embodiment of the present application, the negative pressure siphon well is also connected with a pretreatment device for treating domestic sewage; the pretreatment device includes at least one sewage collection tank, each sewage collection tank communicates with a grid well at the same time, and the grid well communicates with the negative pressure siphon well 1.
[0039] Through the pretreatment device, the domestic sewage entering the negative pressure siphon well 1 can be pretreated under the action of treatment devices such as the grid well, so that larger impurities are filtered out and the drainage can be smooth and stable.
[0040] Further, there are at least two collection tanks, and among the at least two collection tanks, at least one collection tank is an oil separation tank, and at least one collection tank is a septic tank.
[0041] In this way, the kitchen sewage and toilet sewage can be collected simultaneously through the oil separation tank and the septic tank respectively, and the applicability is wider.
[0042] In addition, the negative pressure siphon tank 4, the vacuum pumping device, the dry sewage pump 6 and related control devices can form a negative pressure control station 7; compared with the traditional siphon technology, the negative pressure control station 7 has made a large number of improvements and extended extensions in the following aspects:
[0043] 1. Expand the volume of the siphon bucket - transform the siphon bucket into a negative pressure siphon tank 4, with the volume expanded to avoid sharp changes in negative pressure during the operation of the negative pressure system, enhance the anti-shock ability of the negative pressure inside the system, and achieve simultaneous water conveyance at multiple points.
[0044] 2. Increase the suction negative pressure of the vacuum pump 5 - enhance the negative pressure inside the negative pressure siphon tank 4 and maintain the stability of the system negative pressure. When the water absorption elevation is fixed, the vacuum pump 5 can enhance the negative pressure inside the negative pressure siphon tank 4, which can improve the siphon water conveyance along the pipeline network and extend the water collection distance. Under negative pressure conditions, air in the sewage is likely to precipitate, and the existence of the vacuum pump 5 can keep discharging this precipitated air into the atmosphere to maintain the constancy of the negative pressure inside the negative pressure siphon tank 4 and the negative pressure siphon pipeline network 3.
[0045] 3. Add instruments and electric valves - control and protect the vacuum pump 5 and the dry sewage pump 6.
[0046] The control system of the negative pressure control station 7 has a high degree of automation - adopting the existing PLC + HMI + 4G Internet of Things monitoring. After the project is completed, many villages and towns are relatively remote, and the negative pressure stations are also built village by village with a large number. It is not convenient for operation and management, which requires a high degree of automation of the control system to achieve remote professional management. With a high degree of system automation, automatic drainage can be realized; remote fault alarm; remote monitoring and automatic collection of operation data.
[0047] In summary, the negative pressure siphon drainage system effectively solves the problems such as difficult construction and infiltration and exfiltration that are difficult to solve by gravity pipe networks. Based on the traditional siphon technology, it greatly increases the number of sewage collection wells and the collection distance. The pipe network does not require slope setting, has flexible pipe laying, can be laid openly, has a small pipe diameter, etc., making the construction of the drainage pipe network simpler and faster.
[0048] Please refer to Figure 5 As shown, a laying structure of a drainage system is applied to rural drainage, including a negative pressure siphon drainage system as described in one of the above technical solutions; the negative pressure siphon tank 4 is arranged on a laying ground, and there are multiple negative pressure siphon tanks 4 which are distributed in a divergent manner around the negative pressure siphon tank 4 as the center on the laying ground; the negative pressure siphon well 1 is used to collect domestic sewage of at least one farmer household.
[0049] By adopting the above negative pressure siphon drainage system, the laying structure of the drainage system can be applicable to the sewage drainage of rural long distances and multiple points. The negative pressure siphon pipeline network 3 is laid in the way of water supply pipes, with strong laying randomness, no slope requirement, can climb appropriately, can be laid openly, can avoid structures, and the construction of crossing roads and rivers is simple.
[0050] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the protection scope of the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
