Reacher On The Process Of Screw Transportation And Separating Of Two Phase Of Gas And Solid

Load onto ship in water transport transport material flow system of the bulk cargo, in transport, links of unloading a ship, Shiping load and unload technology one important and weak link, bulk cargo unload a ship technology and research that equip become supplies carry technological field an important research branch! already. The ones that unloaded a ship in the continuous bulk cargo are when fetches the material, vertical sending, link that the level sends,etc., The key technological link fetches the course of the material, The quality of fetching the device performance of the material is to influence and restrict the essential influence factors of the ability and efficiency of the unloading a ship machine in succession of bulk cargo. The complexity of the medium mechanics characteristic of the bulk cargo, the complicated sport that the bulk cargo goes through in the course of fetching the material, Break up grains of supplies with choose material complicated interaction relation of device determine and choose material degree of difficulty that mechanism study. So, a great technological difficult problem in the reseach which fetches the material device , To raise bulk cargo efficiency of unloading a ship of quay it, reduce and unload a ship cost.The ones that flowed to the supplies and air two phase in the specific spiral in main research contents of this text sends and carry on the theory and analyse and combine experimental study with the separation process, Sport regularity that spiral send and separating flows to grasp angry careless two, Analyse and ration to confirm spiral pattern, size, rotational speed, air current speed and supplies characteristic,etc. impact on send and the separating nature attitude of the factor, Develop the spiral and sucks the material device and puts forward corresponding design theory and method on this basis.The design theory and method of proposition of this text will make the spiral suck the material device and have fine fetching the ability of the material in succession , Whether it is low extremely cabin amount not clear, air dust removal amount not smaller, to all kinds of unload a ship in succession by model, type unloaded a ship and unload there aren't supplies , Become one pair of taking type unloading a ship machines, Wave form surround person who unload a ship of bringing etc., bury and blow board person who unload a ship, spiral person whounload a ship, chain fight person who unload a ship bulk cargo head of the unloading a ship machine choose the material device in succession. Performance fine spiral device hopeful to replace existing horizontal spiral collect material impeller support material device and hopper kind to choose but material dtevice have wide application prospect and great to suck material economic meaning.
