Summary of the invention
Technical problem:The steam hose that exists to active sand lifting device in the prior art is prone to obstruction, less stable and installation complicated technology problem, the utility model provide a kind of promote effective, steam hose is difficult for obstructions, single unit system good stability, install simply, the active sand lifting device of long service life.
Technical scheme:A kind of active sand lifting device of the utility model comprises the person in charge, is arranged on the sandpipe that on said person in charge top, is arranged on to be responsible for inner sand passage and the steam hose carried; Said last pipeline, middle pipeline and the following pipeline of sand passage of carrying for connecting successively from top to bottom; Said going up between pipeline and the middle pipeline is provided with adapter sleeve; In be provided with the exhaust adapter sleeve between pipeline and the following pipeline, said adapter sleeve be responsible between, be respectively arranged with between exhaust adapter sleeve and the person in charge and fix spacing retainer plate; The said top that goes out sandpipe is taper, goes out sandpipe and is provided with inlet channel and sand export, and said inlet channel upper end is connected with external air source, and the lower end is connected with steam hose, and the lower end of said sand export is connected with last pipeline; Said exhaust adapter sleeve comprises exhaust adapter sleeve body, is arranged on interior pipe, air inlet and air chamber on the said exhaust adapter sleeve body; Said air inlet is positioned at pipe one side; Said air chamber is the cavity around interior pipe; The upper end of air inlet is connected with steam hose, and the lower end is communicated with air chamber, and the tube wall of interior pipe is provided with the pore that is communicated with air chamber.
The utility model is installed in the active sand filter; Following pipeline buries among active sand particle; Compressed Gas gets into the exhaust adapter sleeve from air inlet through steam hose; After air chamber evenly distributes, get into and carry among the sand passage, the active sand particle of bottom, filter tank is promoted to out the sandpipe top through pore.
Beneficial effect:Compared with prior art, the utility model is provided with the pore that is communicated with air chamber in the exhaust adapter sleeve, can stop effectively that active sand particle gets into steam hose from carrying the sand passage, thereby guarantee that steam hose does not get clogged; The pyramidal structure of sand export can be so that active sand particle produce accumulation at the sand export place, next step operation of smooth and easy entering; The retainer plate that is provided with in the utility model can with steam hose with propose fixing being installed among the person in charge of sand passage, this has just guaranteed to put forward the stability of sand device when operation, and easy for installation; The air chamber of the utility model makes compressed air evenly distribute, and also can reduce the vibrations of device.Active sand lifting device serviceability of the utility model after the improvement and life-span all are improved.
