Embodiment Construction

[0029] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1 to Figure 4 As shown, a propeller blade angle adjustment structure of the present invention includes a blade 3 and a blade seat 1, and the blade seat 1 is arranged along the circumferential direction with three installation planes for installing the blades, and the blades 3 are installed on the corresponding installation planes and extend radially outward.

[0031] The blade 3 is composed of a root connecting plate 31 and a blade body 32. A circular groove 6 is provided at the center of each mounting plane on the blade seat 1, and it is connected with a circular protrusion 7 at the root connecting plate 31 of the blade 3. match.

[0032] The root connecting plate 31 of the blade 3 is arranged with four arc-shaped adjusting long holes along its circumferential direction, and the locking bolts 2 pass throug...

Abstract

The invention discloses a propeller blade angle adjusting structure. The structure comprises a blade and a blade seat, the blade seat is circumferentially provided with at least two mounting planes for mounting blades, the blades are mounted on the corresponding mounting planes, every blade is composed of a root connecting plate and a blade body, a circular groove is arranged in the circular center of every mounting plane of the blade seat, and the circular grooves cooperate with circular projections on the root connecting plates of the blades; and the root connecting plate of every blade is circumferentially provided with at least one circular arc-shaped adjusting long hole, a locking bolt traverses through every arc-shaped adjusting long hole, the rod portion of every locking bolt is inthreaded connection with the corresponding mounting plane, and the head of every locking bolt is in adjustable compression fit with the corresponding root connecting plate. The structure changes the connection modes of traditional blades and blade seats, and is correspondingly provided with the blade angle adjusting function to simply and fast realize the adjustment of the blade angle, so the slurry mixing effect and the motor current meet requirements.

Description

technical field [0001] The invention belongs to the technical field of papermaking equipment, and in particular relates to a propeller blade angle adjustment structure. Background technique [0002] The propeller is mainly used for the circulation and stirring of the stock tank to keep the stock in a suspended state and to ensure that the components of the paper are evenly distributed in the stock. In actual operation, the blade angle of the propeller is directly related to the suspension state of the slurry and the uniform distribution of the slurry, and without changing the blade specification, adjusting the blade angle can make the slurry mixing effect and the motor current more in line with the requirements. [0003] The invention patent of notification number CN109026757A discloses a blade angle adjustment device, which includes guide vane body, blade, impeller hub, motor shaft and locking device. The push rod is provided with a keyway, which is sleeved in the central p...
