The present invention belongs to the field of medical devices, and discloses a multifunctional disposable medical sharps storage box, including a box body top surface, a box body side wall and a box body bottom surface, wherein the box body top surface, the box body side wall and the box body bottom surface are integrally formed, and the box body top surface includes a sharps delivery port, a disposable cover plate, and an input channel, and the box body top surface also includes two slide grooves and a disposable cover plate fixing portion, and the disposable cover plate also includes an integrated shearing device, and a perspective layer is arranged on the box body side wall at a position above one-third of the height of the box body top. The multifunctional disposable medical sharps storage box disclosed by the present invention has the advantages of simple structure, comprehensive functions, high safety, economical and practical, and is more in line with the operating habits of medical staff, and has a better user experience, and has obvious beneficial effects compared with the prior art.

The invention discloses a goaf fire preventing and extinguishing method based on wind flow distribution and dry ice phase change. The method comprises the following steps that the wind flow intersection condition of a goaf and a coal face is measured; detecting the influence range when the dry ice is sublimated into CO2 gas in a laboratory; putting dry ice in the goaf; during stoping, after the goaf roof collapses, the goaf roof coal rock falls onto the heat preservation box filled with the dry ice, the heat preservation box is broken, and the dry ice is buried by the goaf roof coal rock and sublimates to form CO2 gas which is diffused all around for fire prevention and extinguishment. According to the method, the heat preservation boxes filled with the dry ice are arranged in the direction parallel to the coal face and are divided into sections according to wind flow intersection in the goaf, and it is guaranteed that CO2 gas formed after sublimation of the dry ice is evenly distributed in the goaf to the maximum extent. The dry ice in the heat preservation box does not generate phase change when being located in a heat dissipation zone, and sublimates after being smashed by goaf roof coal rocks after falling down when being located in an oxidation zone where spontaneous combustion is most likely to happen, and accurate fire prevention and extinguishing are achieved.

The utility model discloses an animal excrement composting device, including composting bucket, composting bucket is cylindrical structure, and the bottom of composting bucket is plane structure and is provided with four supporting legs, and the top of composting bucket is open type interface and is hinged with upper cover plate. The device improves the composting efficiency of animal excrement through the synergies of stirring mechanism, gas injection mechanism and heating plate. The spiral stirring blade ensures uniform mixing of materials, promotes full contact between aerobic microorganisms and excrement, the annular pipe design of the gas injection mechanism uniformly delivers oxygen through multiple exhaust ports, optimizes the aerobic fermentation environment, and the heating plate is attached to the inner wall to provide stable heat, maintain the appropriate fermentation temperature, and shorten the composting period. The temperature sensor monitors in real time and automatically adjusts the operating state of each component through the controller to avoid temperature fluctuations during the fermentation process. This multifunctional integrated design makes the composting process more efficient, especially suitable for small and medium-sized farms to quickly process excrement and produce high-quality organic fertilizer.
