The application discloses a coal mine underground integrated intelligent circulating leak-stopping system, which comprises a single-bag pipeline cleaning and plugging device, a two-plugging-one-injection hole sealing device and an intelligent circulating leak-stopping pump truck, two pipeline fixing sleeves are symmetrically arranged at the left and right ends of the bag of the single-bag pipeline cleaning and plugging device, the right ends of a leak-stopping pipe and a water injection cleaning pipe are connected with a leak-stopping and cleaning conversion valve, the right end outlet of the leak-stopping and cleaning conversion valve is arranged in a fissure sealing section, and the left end of the leak-stopping pipe is connected with the intelligent circulating leak-stopping pump truck. The leak-stopping and cleaning conversion valve is used for realizing the circulating operation of leak-stopping and cleaning of the fissure sealing section, timely cleaning of the leak-stopping pipe can effectively prevent the leak-stopping pipe from being blocked, the grouting leak-stopping effect is greatly improved, meanwhile, the automatic control of the circulating grouting leak-stopping is realized through the intelligent controller, the working strength is reduced, the working failure in the leak-stopping grouting work is reduced, the normal grouting leak-stopping work is ensured, and the leak-stopping effect and the leak-stopping efficiency are further improved.

The utility model provides a kind of peritoneal dialysis solution fractionation sampling mixing device, comprising: several ration cabin, each ration cabin is connected with extraction mechanism;Mixing cabin, each ration cabin is communicated with mixing cabin, the communication of each ration cabin and mixing cabin is provided with first switch mechanism, and mixing mechanism is provided in mixing cabin. The device is integrated multiple sampling, after single sampling, sample is stored in the device until mixing is stored finally, avoid multiple shuffling leading to sample pollution affecting detection accuracy, at the same time, the device completes multiple sampling alone, avoid the problem that sample is stored in order after each sampling, integrated device can store sample after each sampling, peritoneal dialysis bag can be handled after each sampling is completed, avoid multiple peritoneal dialysis bag stacking, operation is more simple and orderly, reduce the work burden of medical staff, reduce the possibility of work failure.

The utility model relates to the technical field of firework production, and disclose a kind of compacting equipment for firework production, including L type board, further include: fixedly connected to the surface of L type board lug, the top of the lug is equipped with mounting slot, the surface of L type board is rotatably penetrated by pivot, the surface of pivot is fixedly equipped with rotating frame, the top of the rotating frame is equipped with compaction mechanism and is equipped with through slot;The utility model is when using, staff presses plate and can drive lifting frame to drop, connecting plate drives compaction rod to drop, after, raw material inside firework paper tube can be compacted by compaction rod, after that, staff will open rotating frame and can take out firework paper tube and replace, this process is more convenient, and can reduce work failure, solve the current part firework compacting operation, staff uses compaction rod to compact raw material inside paper tube, not only more time-consuming and laborious, and prone to omission and influence firework quality problem.
