Description

Technical Field

[0001] The utility model relates to the field of biogas pipelines, in particular to an automatic drainage device for biogas pipelines. Background Art

[0002] Condensation is a common and thorny issue during biogas transportation. Because biogas pipelines often traverse diverse environmental conditions and terrain, the temperature and pressure within the pipelines fluctuate with changing external factors. These fluctuations cause large amounts of condensation to form on the pipeline walls, a phenomenon that is particularly pronounced in cooler regions or seasons.

[0003] If condensate is not promptly discharged, it can cause numerous harmful effects. First, it will gradually accumulate at the bottom of the pipe, forming a water blockage that hinders the smooth flow of biogas. Severe water blockage can even cause complete blockage of the pipe, disrupting biogas delivery and seriously affecting the continuous operation of the production line. Second, long-term accumulation of condensate can corrode the pipe material, shortening its service life. Furthermore, condensate can carry impurities and bacteria within the pipe, contaminating the quality of the biogas and affecting its subsequent utilization.

[0004] Currently, the treatment of condensate in biogas pipelines primarily relies on a traditional solution: installing a downward-facing valve on the pipeline and manually opening it periodically to drain it. While this method is simple and straightforward, it has significant drawbacks and shortcomings in practice. Manual periodic drainage has a low degree of automation and requires significant human resources. Workers are required to regularly inspect the pipelines and manually open the valve based on the accumulation of condensate. This not only increases labor costs but is also susceptible to human factors, such as negligence and misoperation, which can lead to untimely or excessive drainage, impacting the stability of biogas transmission. To address this issue, we have proposed an automatic drainage device for biogas pipelines. Utility Model Content

[0029] See also Figure 1-4 A biogas pipeline automatic drainage device includes a water outlet tank 1, a water storage tank 2 is provided on one side of the water outlet tank 1, a ball valve 6 is provided on the top of the water outlet tank 1, and a drain port 4 is provided at the bottom end of the water storage tank 2, and further includes:

[0030] The scraper assembly is respectively arranged inside the water outlet tank 1 and the water storage tank 2, and is used to scrape off the condensed water on the inner wall of the water outlet tank 1 and the linkage rod 5;

[0031] The automatic drainage component is arranged at the lower end of the water storage tank 2 and is used to discharge condensed water. By introducing the automatic drainage component and the scraper component, the condensed water can be automatically discharged, which significantly improves the degree of automation, reduces labor costs, reduces the impact of human factors, and can automatically remove the condensed water on the inner wall of the pipeline, thereby comprehensively reducing the adverse effects of condensed water on biogas transportation.

[0032] Furthermore, four water outlet tanks 1 are provided and arranged in parallel, and a drainage pipe 7 is provided between the four water outlet tanks 1 and the water storage tank 2 .

[0033] Furthermore, the drain pipe 7 is arranged in an inverted L shape.

[0034] Furthermore, the four water outlet tanks 1 are connected together through drainage pipes 7 respectively. The top of the water outlet tank 1 far away from the water storage tank 2 is fixedly connected with a ball valve 6, and the four water outlet tanks 1 close to the water outlet tank 1 are connected to the water storage tank 2 through a connecting pipe.

[0035] Furthermore, the four water outlet tanks 1 are made of stainless steel.

[0036] Furthermore, the scraper assembly is provided with multiple components respectively arranged inside the four water outlet tanks 1 and the water storage tank 2. At the same time, the scraper assembly is also continuously working under the action of the float 8 through the height of the water level to remove the condensed water attached to the inner wall of the water outlet tank 1 and the water storage tank 2. As the water level rises, the scraper bar 10 continuously scrapes the inner wall, scrapes off the condensed water and discharges it with the water flow. Since the scraper bar 10 is made of rubber, it has good elasticity and wear resistance, which can ensure a close fit with the inner wall and improve the scraping effect.

[0037] Furthermore, multiple scraper assemblies include a float 8, a fixed ring 9, a scraper strip 10, a fixed rod 11 and a reinforcement ring 12. The scraper strip 10 is fixedly connected to the outer wall of the fixed ring 9. Multiple fixed rods 11 are provided and are arranged around the inner wall of the fixed ring 9. The tops of the multiple fixed rods 11 are fixedly connected to the fixed ring 9, and the bottoms of the multiple fixed rods 11 are respectively fixedly connected to the tops of the float 8. The reinforcement ring 12 is fixedly connected to the upper ends of the multiple fixed rods 11.

[0038] Furthermore, the scraper strip 10 is made of rubber, and the outer wall of the scraper strip 10 is respectively adhered to the inner wall of the water outlet tank 1 and the water storage tank 2 .

[0039] Furthermore, the automatic drainage device includes a sealing plate 3, a linkage rod 5, a fixed plate 13 and a telescopic rod 15. The fixed plate 13 is fixedly connected to the inner wall of the water storage tank 2 through a connecting rod. The bottom of the fixed plate 13 is slidably connected to the top of the movable plate 14 through the telescopic rod 15. A spring is fixedly connected between the fixed plate 13 and the movable plate 14. The bottom of the movable plate 14 is fixedly connected to the top of the linkage rod 5. The bottom of the telescopic rod 15 extends to the upper end of the drain outlet 4 and is fixedly connected to the sealing plate 3. The bottom of the sealing plate 3 corresponds to the bottom of the water storage tank 2. On the inner wall of the biogas transmission pipeline, when the condensed water accumulates to a certain level, the automatic drainage component begins to work. Specifically, when the water level rises, the float 8 rises with the water level. The rise of the float 8 will drive the movement of the linkage rod 5, and then the movable plate 14 moves upward under the action of the telescopic rod 15. At this time, due to the action of the spring, relative movement occurs between the movable plate 14 and the sealing plate 3, so that the sealing plate 3 is separated from the bottom inner wall of the water storage tank 2, thereby opening the drain port 4, and the condensed water flows out through the opened drain port 4 under the action of gravity, realizing automatic drainage.

[0040] Working principle: When the condensed water in the biogas transmission pipeline accumulates to a certain level, the automatic drainage component begins to work. Specifically, when the water level rises, the float 8 rises with the water level. The rise of the float 8 will drive the movement of the linkage rod 5, and then the movable plate 14 moves upward under the action of the telescopic rod 15. At this time, due to the action of the spring, relative movement occurs between the movable plate 14 and the sealing plate 3, so that the sealing plate 3 is separated from the bottom inner wall of the water storage tank 2, thereby opening the drain port 4. The condensed water flows out through the opened drain port 4 under the action of gravity, realizing automatic drainage. At the same time, the scraper component is also working continuously under the action of the water level on the float 8 to remove the condensed water attached to the inner walls of the water outlet tank 1 and the water storage tank 2. Condensed water, the scraper 10 will continuously scrape the inner wall as the water level rises, scrape the condensed water off and discharge it with the water flow. Since the scraper 10 is made of rubber, it has good elasticity and wear resistance, which can ensure a close fit with the inner wall and improve the scraping effect. In addition, the provision of the reinforcement ring 12 can enhance the overall structural stability of the scraper assembly, ensuring that it is not easily damaged during long-term use. When the condensed water in the biogas transmission pipeline is completely discharged, the water level drops and the float 8 drops accordingly. Under the action of the spring, the movable plate 14 applies pressure to the sealing plate 3 through the linkage rod 5, so that the sealing plate 3 is re-fitted with the inner bottom end of the water storage tank 2, and the drain port 4 is closed. At this time, the scraper assembly continues to work to ensure the cleanliness of the inner wall.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
