A warming and heat preservation biogas pond

Abstract

The invention discloses a biogas pool with a temperature increase and retention function. The biogas pool comprises a pool body, a stirring shaft, a heat retention sleeve, a temperature sensor and a heating coil; an air duct, a motor and a feeding channel are sequentially arranged at the upper end of the pool body; a filter layer is arranged at the bottommost end of the air duct, and the air duct is further provided with an exhaust fan; the motor is connected with the stirring shaft in a driving manner, the stirring shaft is arranged in the pool body, and a stirring paddle is arranged on the stirring shaft; the heat retention sleeve is arranged in the pool body, an unfreezing sleeve is further arranged outside the heat retention sleeve, and the hot-water inlet of the unfreezing sleeve is located on the upper right side of the pool body; the temperature sensor is further arranged on the right inner side of the pool body and is electrically connected with a temperature alarm arranged outside the pool body, and a display screen used for displaying the temperature is arranged on the temperature alarm. By the arrangement, insufficient reaction is avoided, normal gas supply is guaranteed, leakage is prevented, integral strength is enhanced, service life is prolonged, temperature control effect is good, temperature adjusting speed is high and efficient, and the biogas pool is environment friendly and free of pollution.

Description

technical field [0001] The invention relates to the technical field of biogas pits, in particular to a temperature-increasing and heat-retaining biogas pit. Background technique [0002] The biogas digester can be used for about 20 years. Making good use of the biogas digester can not only save energy, improve and protect the environment, but also save chemical fertilizers and pesticides, improve the yield and quality of crops, and promote and drive the development of the breeding industry. A septic tank filled with human and animal feces, straw and other organic substances, and the mouth of the tank is sealed; under suitable conditions, the flammable gas produced; through the fermentation of biogas in the biogas digester, a clean and hygienic new biogas energy is formed; however, today's There are also various problems in the biogas digester, especially in winter in the north, due to the drop in temperature, the fermentation in the pond slows down, resulting in a small amou...

[0002] The biogas digester can be used for about 20 years. Making good use of the biogas digester can not only save energy, improve and protect the environment, but also save chemical fertilizers and pesticides, improve the yield and quality of crops, and promote and drive the development of the breeding industry. A septic tank filled with human and animal feces, straw and other organic substances, and the mouth of the tank is sealed; under suitable conditions, the flammable gas produced; through the fermentation of biogas in the biogas digester, a clean and hygienic new biogas energy is formed; however, today's There are also various problems in the biogas digester, especially in winter in the north, due to the drop in temperature, the fermentation in the pond slows down, resulting in a small amount of biogas, and the long-term use of the gas guide will also be due to the accumulated biogas and its content. Some impurities in the air will block the airway, seriously affecting people's normal quality of life in winter
