Description

Technical Field

[0001] The utility model relates to the technical field of stirring blades, in particular to a blade convenient for maintenance. Background Technique

[0002] A stirring blade is a tool for stirring and an important component in a mixing device. The structure and blade type of the blade determine the overall stirring form of the liquid in the kettle.

[0003] Stirring blades are widely used in the chemical industry. The stirring blades in the chemical industry require regular inspection and maintenance by staff to avoid the impact of chemicals on the blades. However, the common blades on the market are usually welded to the outer wall of the paddle shaft, and the paddle shaft is usually installed on the main shaft of the equipment through bolts. When maintenance of the blade is required, the bolts connecting the paddle shaft and the main shaft of the equipment need to be disassembled first, and then the paddle shaft and the main shaft of the equipment need to be separated to maintain the blade. It is impossible to disassemble a single blade, and the installation and disassembly through the bolt connection method are very troublesome. Content of the Utility Model

[0004] The purpose of the utility model is to provide a blade convenient for maintenance to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A blade convenient for maintenance, including a blade, an installation plate is fixedly installed on the side wall of the blade, a through groove is opened on the installation plate, a paddle shaft is clamped on the outer wall of the installation plate, an installation groove is opened on the paddle shaft, and a disassembly and assembly mechanism for conveniently disassembling and assembling the blade is arranged on the installation plate. By setting the disassembly and assembly mechanism, a single blade can be quickly disassembled and assembled, which is convenient for staff to maintain the blade. An auxiliary mechanism is arranged on the disassembly and assembly mechanism. By setting the auxiliary mechanism, the stability of the blade can be improved. The disassembly and assembly mechanism includes:

[0006] A clamping block, the clamping block is slidably connected to the inner wall of the installation plate, a limiting groove is opened on the inner wall of the paddle shaft, and the outer wall of the clamping block is attached to the inner wall of the limiting groove.

[0009] Preferably, the auxiliary mechanism includes a knob which is threadedly connected to the outer wall of the threaded rod. By setting the knob and cooperating with the turntable, the rubber block can be driven to closely adhere to the outer wall of the mounting plate.

[0010] Preferably, a turntable is rotatably connected to the side wall of the knob.

[0011] Preferably, a rubber block is fixedly installed on the side wall of the turntable. The threaded rod can be limited by the interference fit between the rubber block and the mounting plate, avoiding the displacement of the threaded rod inside the through groove.

Detailed implementation mode

[0023] As Figures 1-5 shown, the utility model provides a technical solution: a blade convenient for maintenance, including a blade 1. An installation plate 2 is fixedly installed on the side wall of the blade 1. A through groove 3 is opened on the installation plate 2. The size of the installation groove 5 is exactly the same as that of the installation plate 2. A blade shaft 4 is clamped on the outer wall of the installation plate 2. An installation groove 5 is opened on the blade shaft 4. A disassembly and assembly mechanism 6 for conveniently disassembling and assembling the blade 1 is arranged on the installation plate 2. By setting the disassembly and assembly mechanism 6, the single blade 1 can be quickly disassembled and assembled, which is convenient for the staff to maintain the blade 1. An auxiliary mechanism 7 is arranged on the disassembly and assembly mechanism 6. By setting the auxiliary mechanism 7, the stability of the blade 1 can be improved.

[0024] The above-mentioned disassembly and assembly mechanism 6 includes a clamping block 61, a threaded rod 62, a reed 63, a limiting groove 64, and a limiting block 65. The clamping block 61 is slidably connected to the inner wall of the installation plate 2. A limiting groove 64 is opened on the inner wall of the blade shaft 4. The outer wall of the clamping block 61 is attached to the inner wall of the limiting groove 64. The limiting groove 64 is used in cooperation with the clamping block 61 to limit the installation plate 2. One end of the threaded rod 62 is fixedly installed on the outer wall of the clamping block 61. The other end of the threaded rod 62 is fixedly installed with a limiting block 65. The outer wall of the threaded rod 62 is attached to the inner wall of the through groove 3. By pushing the threaded rod 62 to move on the inner wall of the through groove 3, the clamping block 61 can be driven to move towards the inside of the installation plate 2. One end of the reed 63 is fixedly installed on the side wall of the clamping block 61. The other end of the reed 63 is fixedly installed on the inner wall of the installation plate 2. After the installation plate 2 is inserted into the inside of the installation groove 5, the threaded rod 62 is released. At this time, the clamping block 61 can be pushed out of the installation plate 2 through the elasticity of the reed 63, and the clamping block 61 enters the inside of the limiting groove 64.

[0025] The above-mentioned auxiliary mechanism 7 includes a knob 71, a turntable 72, and a rubber block 73. The knob 71 is threadedly connected to the outer wall of the threaded rod 62. The side wall of the knob 71 is rotatably connected to the turntable 72. A rubber block 73 is fixedly installed on the side wall of the turntable 72. By rotating the knob 71 in cooperation with the turntable 72, the rubber block 73 can be driven to closely adhere to the outer wall of the installation plate 2. At this time, the threaded rod 62 can be limited by the rubber block 73 in cooperation with the turntable 72 and the knob 71, so that the threaded rod 62 is stably placed inside the through groove 3.

[0026] Working principle: When it is necessary to disassemble and maintain the blade 1, pinch the two groups of threaded rods 62 so that the two groups of threaded rods 62 move synchronously and approach each other on the inner wall of the through groove 3. At this time, the threaded rod 62 will drive the clamping block 61 to gradually slide into the interior of the mounting plate 2 and compress the reed 63. At the same time, the clamping block 61 will gradually disengage from the limiting groove 64. When the clamping block 61 completely disengages from the limiting groove 64, the mounting plate 2 can be pulled outwards to move it out of the mounting groove 5. At this time, the disassembly of the blade 1 can be completed without disassembling the paddle shaft 4, and a single blade 1 can be disassembled, which is convenient for the staff to maintain the blade 1. When it is necessary to install the blade 1, first pinch the two groups of threaded rods 62 to make the threaded rod 62 drive the clamping block 61 to completely enter the interior of the mounting plate 2. Then insert the mounting plate 2 into the interior of the mounting groove 5. At this time, release the threaded rod 62. The elasticity of the reed 63 can push the clamping block 61 out of the mounting plate 2 and make the clamping block 61 enter the interior of the limiting groove 64. At this time, the limiting groove 64 and the clamping block 61 are used to limit the mounting plate 2, so as to complete the installation of the blade 1, which is more convenient to use.

[0027] After the clamping block 61 is clamped into the interior of the limiting groove 64, rotate the knob 71 to drive the turntable 72 to gradually approach the mounting plate 2 until the rubber block 73 on the side wall of the turntable 72 is closely attached to the outer wall of the mounting plate 2. At this time, the rubber block 73, the turntable 72 and the knob 71 are used to limit the threaded rod 62, so that the threaded rod 62 is stably placed in the through groove 3, so that the clamping block 61 can be stably clamped into the interior of the limiting groove 64, improving the stability of the mounting plate 2, and thus improving the stability of the blade 1.

[0028] The above generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
