Problems solved by technology

[0002] The electric feeder device used in most occasions in thermal power plant slag removal system is to reserve a small gap between the rotating shaft and the shell to realize feeding. There are often thermal deformations that make the gap small and cause jamming, which seriously affects the operation.

Embodiment Construction

[0008] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0009] like figure 1 and figure 2 As shown, the straight-toothed rotating shaft includes radial blade 1, axial blade 2, and rotating shaft 3. Radial blade 1 is connected to axial blade 2, radial blade 1 is connected to rotating shaft 3, and axial blade 2 is connected to rotating shaft 3. , the outer circle of the axial blade 2 is equal to the radial blade 1, the axial blade 2 and the shell adopt a small gap, that is, the gap tolerance value, to ensure the seal, and the connection between the axial blade 2 and the radial blade 1 is welding to ensure the tightness The radial blade 1 is six pieces evenly distributed on the rotating shaft, the connection method is welding connection, the radial blade 1 and the shell are in contact with a large gap, and the contact end side of the radial blade 1 and the shell is a staggered rectangular tooth-shape...

Abstract

The invention discloses a straight-tooth-shaped rotation shaft. The straight-tooth-shaped rotation shaft comprises radial blades, axial blades and a rotation shaft, wherein the radial blades are connected with the axial blades, the radial blades are connected with the rotation shaft, the axial blades are connected with the rotation shaft, the size of the outer circle of each axial blade is equal to the size of each radial blade, the axial blades are matched with a housing by adopting small fitting clearance which is tolerance clearance value so as to guarantee sealing, a welding connection mode is adopted between each axial blade and each radial blade so as to guarantee compactness between each axial blade and each radial blade, six radial blades are evenly distributed on the rotation shaft, the six radial blades are connected with the rotation shaft in welding mode, the radial blades are contacted with the housing in large clearance mode, the sides of the radial blades, which are contacted with the housing, form stagger rectangular toothed concave and convex intervals, and each two adjacent radial blades are arranged in stagger mode. The straight-tooth-shaped rotation shaft has the advantages of being simple in structure, convenient to operate, quick to install, tight in air locking, good in work environment, safe and reliable, saving labor in operation and the like.

Description

technical field [0001] The invention relates to a straight-toothed rotating shaft, which is especially suitable for the feeding rotating shaft part of an electric feeder in a slag removal system of a thermal power plant. Background technique [0002] The electric feeder device used in most occasions in thermal power plant slag removal system is to reserve a small gap between the rotating shaft and the shell to realize feeding. There is often thermal deformation, which makes the gap small and jams, which seriously affects the operation. Contents of the invention [0003] The invention develops a straight-toothed rotating shaft, and its purpose is to provide a straight-toothed rotating shaft with simple structure, labor-saving and convenient operation, quick installation, uniform feeding, good working environment, safety and reliability. [0004] In order to achieve the above object, the device of the present invention is achieved through the following technical solutions. ...
