The invention relates to the technical field of breathing machines, and discloses an efficient filtering and heat dissipation device of a medical breathing machine, the efficient filtering and heat dissipation device comprises a filtering frame, the top of the filtering frame is fixedly connected with the breathing machine, and a filtering part is arranged in the filtering frame; the filtering component comprises a triangular frame, the surface of the triangular frame is fixedly connected with the inner wall of the breathing machine, a mounting frame is fixedly connected to the bottom of the triangular frame, a clamping groove is formed in the inner wall of the mounting frame, and two side plates are arranged in the mounting frame. When oxygen flows in the filter frame, the sieve pore plate can treat the oxygen entering the filter frame, impurities such as cotton fibers in the oxygen are prevented from entering the filter frame, the filter plate can filter the oxygen again after the sieve pore plate filters the oxygen, and the situation that the quality of the oxygen is poor due to the fact that the oxygen contains the impurities is avoided; when the oxygen in the filter frame enters the breathing machine, the filter bag can filter small particles in the oxygen again.

The utility model discloses an anti-blocking dredging device of a pipeline elbow and an ore pulp conveying pipeline system.The anti-blocking dredging device of the pipeline elbow comprises an anti-blocking mechanism and a dredging mechanism, and the anti-blocking mechanism comprises the pipeline elbow used for being communicated with two conveying pipes and a stirring assembly used for stirring conveyed media; the stirring assembly is mounted on the pipeline elbow, and the pipe diameter of the pipeline elbow is larger than that of the conveying pipe; the dredging mechanism comprises a flushing assembly used for diluting and / or flushing the accumulated and blocked medium and a sewage discharging assembly used for discharging the accumulated and blocked medium, and the flushing assembly and the sewage discharging assembly communicate with the pipeline elbow. The device not only can prevent media from being blocked in the conveying process, reduce the blocking frequency of the media at the elbow position of the pipeline and improve the conveying smoothness of the pipeline, but also can quickly dredge the interior of the blocked pipeline and guarantee stable and efficient conveying of the media. And the device can monitor the blockage condition and automatically conduct dredging operation, and time and labor are saved.
