STRUCTURE OF AXIAL-TYPE MULTISTAGE TURBINE

The present invention relates to a structure of an axial-type multistage turbine. To this end, the present invention provides the structure of the axial-type multistage turbine including a mixed-type turbine (100) having an inner part filled with a fluid, and the mixed type turbine comprises: a body (101) having a space part (105) in which a fluid is filled, and an inlet (102) and an outlet (103) respectively formed at an upper end and a lower end thereof; a rotary shaft (140) provided in a center of the body (101) to be rotated at a high speed and having a discharging hole (107); at least one first rotational blade (110) provided to be integrated with the rotary shaft (140); a plurality of second rotational blades (120) provided to be integrated with the rotary shaft (140) at a predetermined interval; and the body (101) comprising a reception hole (106) formed inside the upper end thereof and a plurality of fixing blades (130) provided to be fixed at a lower end of the body. The present invention having the above-mentioned configuration enables a user to selectively use a turbine structure among an immersion type, a collision type, and a recoil-operated type in accordance with circumstances on site, and particularly, can maximize efficiency by superlatively forming angles of a blade and a nozzle of the turbine, thereby providing a good image of a product by satisfying various consumer needs of users by remarkably improving quality and reliability of the product.
