Abstract
The invention discloses a large-suction-force axial flow fan, which comprises a rotating shaft and a fan main body, wherein the fan main body is arranged on the rotating shaft and is formed by more than two blades, the two side surfaces of each blade are respectively a pressure surface at the air outlet side and a suction force surface at the air inlet side, a round outer frame in coaxial arrangement with the rotating shaft is arranged on the outer periphery of the blade, a circular ring in vertical arrangement to the round outer frame is arranged on the outer periphery of the round outer frame, the large-suction-force axial flow fan also comprises a tubular base body positioned on the outer periphery of the fan main body, a radial annular groove extending into the side wall of the tubular base body is formed in the inner circumference surface of the tubular base body, and the peripheral edge of the annular ring extends into the radial annular groove. After the adoption of the structure, and through the round outer frame arranged on the outer periphery of the blades and the circular ring arranged on the outer periphery of the round outer frame, the peripheral edge of the circular ring extends into the radial annular groove, so a certain labyrinth sealing structure is formed, the wind quantity loss is greatly reduced, and the energy consumption is reduced.

Background technique
Axial-flow blower is usually used in greatly in various air regenerating devices because of its flow, existing axial-flow blower generally comprises rotating shaft and is arranged on the multi-disc blade in rotating shaft, the bi-side of this blade are respectively pressure side and suction surface, although this axial-flow blower can have larger flow traditionally, but because structure arranges unreasonable, make its wind loss large, energy loss is large.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in structure, large suction axial-flow blower that energy loss is little.
In order to solve the problems of the technologies described above, large suction axial-flow blower of the present invention, comprise rotating shaft and be arranged on two fan main bodies that above blade forms in rotating shaft, the bi-side of every blade are respectively the pressure side of air side and the suction surface of inlet side, the periphery of fan blade is provided with the circular housing with the coaxial setting of rotating shaft, the periphery of circular housing is provided with and the vertically arranged annulus of circular housing, also comprise a tubular matrix that is positioned at fan main body periphery, on the inner peripheral surface of tubular matrix, be provided with the radially annular groove extending in tubular base side walls, the periphery of annulus extend into radially in annular groove.
Described tubular matrix comprises left matrix and right matrix two-part of radially splitting, after fan main body is arranged in left matrix and right matrix by fastening piece by left matrix with right matrix is fixing forms complete entirety.
Described tubular matrix comprises upper matrix and the lower substrate along the circumferential direction split, and fan main body forms complete entirety by upper matrix capping after being arranged in lower substrate.
In the sidewall of described tubular matrix, be provided with two above axial annular grooves of along the circumferential direction arranging, described axial annular groove and radially annular groove connect mutually, are provided with the outer shroud that is positioned at axial annular groove on described annulus.
Described tubular matrix is made up of matrix on polylith and lower substrate, and fan main body is placed in respectively between adjacent upper matrix and lower substrate.
The upper and lower surface of described upper matrix and lower substrate is provided with positioning hole and can be inserted into the locating stud in annular groove.
Between described adjacent upper matrix and lower substrate, be provided with seal ring.
Adopt after above-mentioned structure, the annulus that install the circular housing of installing due to the periphery of fan blade and the periphery of circular housing, the periphery of annulus extend into radially in annular groove, makes thus it form certain labyrinth seal structure, greatly reduce the loss of air quantity, reduced energy consumption.
