Problems solved by technology

[0002] At present, most rural biogas digesters are made of cement materials. The construction process is cumbersome, the construction period is long, and the quality is not easy to guarantee. The cement material has poor thermal insulation performance, which is not conducive to high-temperature fermentation. Therefore, some FRP biogas digesters appeared again. FRP biogas digesters are conducive to the realization of industrialized mass production, product standardization and serialization, and have the advantages of light weight and easy installation, but the cost of FRP products is high and expensive, and it is not easy for farmers to Accepted, it is difficult to popularize FRP biogas digesters in rural areas
In addition, there are magnesia cement biogas digesters made of Chinese patent application 200510013002 "composite material for preparing assembled biogas digesters", plastic biogas digesters described in Chinese patent application 200410022220, and biogas combined with three-in-one materials described in Chinese patent application 20051000543. ponds, etc., so far, there is no use of recycled rubber to make biogas digesters

Embodiment 1

[0011] Design and manufacture corresponding steel molds according to the shape, size and reserved seam of the biogas digester; cut the waste rubber into blocks, crush and screen with a pulverizer to make rubber powder below 50 mesh, and then heat it at 200°C Desulfurize the rubber powder at a high temperature, then use a rubber mixer to mix, first add the rubber powder and then add each compounding agent in sequence, the amount of the compounding agent is 1% to 10% of the rubber powder, and the compounding agent is commonly used in the rubber industry Softeners, accelerators, active agents, anti-aging agents, reinforcing fillers, vulcanizing agents, etc., mixed in the rubber mixer to make them evenly mixed and dispersed; firstly lay steel wire and glass fiber or canvas on the aforementioned metal mold as the skeleton , and then the mixed rubber discharged by the rubber mixer is molded in a steel mold to make the assembly of the rubber biogas digester, and finally vulcanized by ...

Description

technical field [0001] The invention relates to a material for building biogas pits, in particular to an assembled biogas pit made of recycled rubber. Background technique [0002] At present, most rural biogas digesters are made of cement materials. The construction process is cumbersome, the construction period is long, and the quality is not easy to guarantee. The cement material has poor thermal insulation performance, which is not conducive to high-temperature fermentation. Therefore, some FRP biogas digesters appeared again. FRP biogas digesters are conducive to the realization of industrialized mass production, product standardization and serialization, and have the advantages of light weight and easy installation, but the cost of FRP products is high and expensive, and it is not easy for farmers to It is accepted that it is difficult to popularize FRP biogas digesters in rural areas. In addition, there are magnesia cement biogas digesters made of Chinese patent appl...
