Description

Technical Field

[0001] This utility model relates to the field of biogas digester technology, specifically to a pipe anti-clogging mechanism for biogas digesters. Background Technology

[0002] A biogas digester is a facility for producing biogas. Biogas is a combustible gas produced by the fermentation of organic matter in an anaerobic environment under specific temperature, humidity, and pH conditions through microbial processes.

[0003] Biogas often contains water vapor. After biogas enters the pipeline from the biogas digester, the water vapor carried in the biogas will gradually condense into water and adhere to the pipe wall due to the temperature difference between the inside and outside of the digester. This will cause the accumulation of condensate and affect the output of biogas. In addition, during the process of biogas discharge, a small amount of biogas sludge will be carried into the pipeline by the airflow. This biogas sludge is prone to adhering to the pipeline and clogging it. Therefore, a pipeline anti-clogging mechanism for biogas digesters is proposed to solve the above problems.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please see Figure 1-4 This embodiment provides a pipe anti-clogging mechanism for a biogas digester, comprising a biogas pipe 1. An anti-clogging component 2 is installed inside the biogas pipe 1 to prevent blockage. The anti-clogging component 2 includes a filter plate 21 for filtration. The filter plate 21 is fixedly connected to the inside of the biogas pipe 1. The filter plate 21 consists of reinforcing ribs 22 and a filter screen 23. A bearing is provided in the middle of the filter screen 23, and a drive shaft 24 is connected to the bearing. One end of the drive shaft 24 is connected to a drive impeller 25 for transmission. A cleaning component 3 for cleaning the reinforcing ribs 22 is provided on the shaft of the drive shaft 24. The other end of the drive shaft 24 passes through the filter plate 21 and is fixedly connected to a water-absorbing component 4 for cleaning the inner wall of the biogas pipe 1.

[0022] As a preferred technical solution in this embodiment: In actual use, the operator can connect one end of the biogas pipeline 1 to the biogas digester and the other end, which is the discharge end, to the corresponding equipment. During the discharge of biogas, the filter screen 23 can effectively filter the biogas, thereby intercepting some floating objects. At the same time, during the discharge of biogas, the transmission impeller 25 will rotate. During the rotation of the transmission impeller 25, the transmission shaft 24 will rotate. During the rotation of the transmission shaft 24, the cleaning component 3 will clean the solid debris attached to the filter screen 23. Meanwhile, the other end of the transmission shaft 24 can drive the water absorption component 4 to rotate. During the rotation of the water absorption component 4, the condensate on the inner wall of the biogas pipeline 1 can be effectively collected, avoiding the situation where the exhaust is not smooth due to the adhesion of condensate.

[0023] Furthermore, in actual use, staff can install a water-absorbing filter layer inside the filter screen 23, such as an activated carbon layer or a calcium carbonate layer, to achieve the effect of drying biogas.

[0024] Example 2:

[0025] Please see Figure 1-4To achieve the effect of cleaning the filter screen 23 and the inner wall of the biogas pipe 1, the cleaning component 3 in this embodiment includes a transmission plate 31, which is fixedly connected to the rod of the transmission shaft 24. Two cleaning brushes 32 for cleaning are symmetrically arranged on the transmission plate 31, and the cleaning brushes 32 are kept in contact with the filter screen 23. The water absorption component 4 includes a transmission seat 41 for installation, which is fixedly connected to the transmission shaft 24. Both ends of the transmission seat 41 are provided with water absorption rollers 42 for cleaning the inner wall of the biogas pipe 1, and the water absorption rollers 42 are in contact with the inner wall of the biogas pipe 1. A drainage groove 43 is opened on the transmission seat 41, and both ends of the drainage groove 43 are located at the bottom of the water absorption rollers 42. A drainage hole 26 for drainage is opened in the transmission shaft 24, and the drainage hole 26 is connected to the drainage groove 43.

[0026] As a preferred technical solution in this embodiment: In actual use, when the transmission shaft 24 drives the transmission plate 31 to rotate, the two cleaning brushes 32 provided on the transmission plate 31 can effectively clean the solid impurities attached to the filter screen 23, thereby effectively avoiding the blockage caused by excessive debris during use. While the transmission shaft 24 rotates, it can drive the transmission seat 41 so that the two water suction rollers 42 can achieve a good adsorption effect on the condensate on the inner wall of the biogas pipe 1. At the same time, when the water suction rollers 42 adsorb too much water, it will flow into the drainage trough 43 under the action of gravity, and finally flow into the drain hole 26 through the drainage trough 43 and finally enter the biogas digester, thereby avoiding the water suction rollers 42 from absorbing too much water after long-term use, which would affect their water absorption effect.

[0027] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
