According to an announcement by the State Intellectual Property Office,NimbaughEnergy Equipment Co., Ltd. has obtained a project entitled "a cold and heat isolation Structure and Screw medium Press containing it", authorized notice No. CN220059907U, the application date is November 2022。

Patent abstract display，The patent includes a screw host, oil and gas separation system, air cooling system, gas and liquid separation system and oil cooling system in the medium pressure case;The oil-gas separation system is connected with the screw host through the oil-gas pipe，The oil-gas separation system communicates with the air-cooling system through the pre-cooling air pipe，The air-cooling system and the gas-liquid separation system are connected through the cooled trachea;Oil and gas separation system is provided with lubricating oil discharge pipe，The oil cooling system is connected with the lubricating oil discharge pipe;The screw main engine, the oil-gas separation system and the gas-liquid separation system are arranged at one end of the medium press box，Air cooling system near the middle of the box;A cold and hot isolating plate extending along the height direction is arranged in the medium pressure case body. The cold and hot isolating plate is used to isolate the screw host, the oil and gas separation system and the gas and liquid separation system from the air cooling system and the oil cooling system.It has a stable and efficient way to keep the temperature of the oil and gas mixture at the oil and gas discharge end of the main engine constant, and effectively prevent the emulsification of lubricating oil。
