Abstract
Reaction type stationary blade fixing device. The cathode suspension device plays a role in supporting a cathode system of the electric dust collector and insulating the cathode system from a supporting position, and a ceramic sleeve of a core part of the cathode suspension device is in direct contact with electric field smoke, so that dust is adhered to the inner wall of the ceramic sleeve, and the creepage phenomenon is easy to generate. The utility model comprises the following components: quiet leaf (4), cushion (2) and sloping block (3), quiet leaf install in mounting groove (5) of installation piece (7), the sloping block install the mounting groove in and press the back of quiet leaf, the cushion install the back of sloping block, the sloping block seat be in the cushion on. The utility model is used for fixing the reaction type stationary blade.
Description
Technical Field
The utility model relates to a reaction type stationary blade fixing device.
Background
The convex midsplit surface of the reaction type stationary blade is irregular in shape during assembly, and is inconvenient to fix due to the irregular shape during compression through the pressure plate. During assembly, the blades are subjected to circumferential impact loads, which tend to cause movement.
Disclosure of Invention
The utility model aims to provide a reaction type stationary blade fixing device.
The above purpose is realized by the following technical scheme:
the utility model provides a fixed blade fixing device of reaction formula, its constitution includes quiet leaf, cushion and sloping block, quiet leaf install in the mounting groove of installation piece, the sloping block install the mounting groove in and press the back of quiet leaf, the cushion install the back of sloping block, the sloping block seat be in the cushion on.
The reaction type stationary blade fixing device is characterized in that a positioning groove matched with the mounting groove is formed in the bottom of the inclined block.
Has the advantages that:
1. the utility model comprises a cushion block and an inclined block, wherein the inclined block is provided with a positioning groove which is matched with the stationary blade mounting groove. During assembly, the static blade is firstly installed in the installation groove, the inclined block and the cushion block are sequentially added to the back of the installation groove, the connection and matching surfaces are tightly attached, and finally the installation groove is tightly pressed on the middle split surface through the pressing plate, so that the fixation of the static blade can be ensured, and the static blade is prevented from moving.
2. The contact surface of the inclined block and the static blade is consistent with the angle of the inner radial surface of the blade root of the static blade, so that the assembly firmness can be ensured.
Description of the drawings:
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view of a swash block;
in the figure: 1. dividing the dough into middle parts; 2. cushion blocks; 3. a stationary blade; 4. a stationary blade; 5. mounting grooves; 6. positioning a groove; 7. and (7) installing the block.
The specific implementation mode is as follows:
example 1:
the utility model provides a fixed device of reaction type quiet leaf, its constitution includes quiet leaf 4, cushion 2 and sloping block 3, quiet leaf install in mounting groove 5 of installation piece 7, the sloping block install the mounting groove in and press the back of quiet leaf, the cushion install the back of sloping block, the sloping block seat be in the cushion on.
Example 2:
according to the reaction type stator blade fixing device of the embodiment 1, the bottom of the inclined block is provided with a positioning groove 6 matched with the installation groove.
The working principle is as follows: the 1-shaped irregular convex midsplit surface of the reaction type static blade is irregular in shape during assembly, when the blade is compressed through the pressing plate, due to the fact that the shape is irregular and not convenient to fix, through the inclined block, the inclined block is consistent with the blade root inner radial surface angle of the static blade, meanwhile, the inclined block is supported and fixed through the cushion block, when the blade is compressed through the pressing plate, the pressing plate and the cushion block contact surface are a plane, and the fixation of the static blade can be guaranteed.
Claims (2)
1. A reaction type stationary blade fixing device is characterized in that: the structure comprises a static blade, a cushion block and an oblique block, wherein the static blade is arranged in a mounting groove of a mounting block, the oblique block is arranged in the mounting groove and pressed on the back of the static blade, the cushion block is arranged on the back of the oblique block, and an oblique block seat is arranged on the cushion block.
2. The reaction-type stationary blade fixing apparatus as claimed in claim 1, wherein: the bottom of the inclined block is provided with a positioning groove matched with the mounting groove.
