The embodiments of this utility model will be described below based on its overall structure.

[0025] Reference Figures 1 to 5 In this embodiment of the present invention, a stirring container with a quick disassembly and assembly mechanism includes: a stirring tank 1, which is a cylindrical container with an open top. A fixed ring cover 2 with an annular structure is fixedly attached to the middle area of ​​the top of the stirring tank 1 by means of a flange or a slot. The fixed ring cover 2 has a through hole in the center, and a connecting end cover 3 is movably inserted into the through hole. A motor 4 is fixedly connected to the top of the connecting end cover 3. The drive shaft of the motor 4 passes vertically downward through the connecting end cover 3 and is rotatably connected to a rotating rod 8 through a coupling or a keyway. The rotating rod 8 extends into the interior of the stirring tank 1, and its surface is evenly provided with snap-fit ​​teeth along the axial direction for installing multiple sets of stirring components 9.

[0026] Four sets of L-shaped clamping plates 5 are fixedly connected to the side of the connecting end cover 3 near the end of the fixing ring cover 2. The surface of the clamping plate 5 has insertion holes, which are inserted and cooperate with the four sets of positioning blocks 6 welded to the fixing ring cover 2 to achieve radial limiting of the connecting end cover 3. Each side of the clamping plate 5 is provided with a set of spring pins 7. The spring pins 7 are fixed to the top of the fixing ring cover 2 by bolts. The spring pins 7 include a fixing seat 71, a limiting baffle 72, a pin 73, a spring 74, and a limiting rod 75. The fixing seat 71 is welded to the fixing ring. On the surface of cover 2, a limiting baffle 72 is vertically welded to the middle area of ​​the bottom inner side. A pin 73 is movably inserted into the through hole of the side plate of the fixing seat 71 and the card plate 5. A limiting rod 75 is welded to one end of the pin 73 near the card plate 5. A spring 74 is sleeved on the surface of the pin 73. One end of the spring 74 abuts against the inner wall of the fixing seat 71, and the other end abuts against the limiting rod 75. Under normal conditions, the spring 74 pushes the pin 73 into the insertion hole of the card plate 5. The limiting baffle 72 restricts the movement range of the limiting rod 75 to prevent the pin 73 from completely coming out.

[0027] The stirring assembly 9 includes a retaining ring 91, a connector 92, a magnetic insert 93, a stirring paddle 94, and a fixing rod 95. The retaining ring 91 has teeth on its inner side that match the engaging teeth of the rotating rod 8, allowing it to be movably engaged with the surface of the rotating rod 8 through tooth meshing. The connector 92 is welded to the outer side of the retaining ring 91. A slot is formed on the side of the connector 92, into which the magnetic insert 93 is movably inserted. One end of the magnetic insert 93 is welded to the stirring paddle 94, and the other end is embedded with a permanent magnet, attracting it to a magnet fixed inside the connector 92. The connector 92 and... The magnetic plug 93 is horizontally inserted through the fixing rod 95 at the insertion point. The mechanical locking of the fixing rod 95 prevents the magnetic plug 93 from axial displacement. A maintenance door 10 is opened on the outside of the mixing tank 1. The maintenance door 10 is connected to the tank body by a hinge and can be locked, making it easy for the operator to enter the tank to disassemble the mixing assembly 9. A feeding pump 11 is fixedly installed in the middle area of ​​the bottom of the mixing tank 1 for discharging materials. A support frame 12 is welded to the bottom edge. The support frame 12 is fixed to the ground by anchor bolts to maintain overall stability.

[0028] The working principle of this utility model is as follows:

[0029] After the motor 4 starts, the drive shaft drives the rotating rod 8 to rotate through the connecting end cover 3. The snap-fit ​​teeth on the surface of the rotating rod 8 engage with the snap-fit ​​teeth on the inner side of the snap ring 91 of the stirring assembly 9, so that the snap ring 91 rotates synchronously with the rotating rod 8. The snap ring 91 drives the magnetic plug 93 and the stirring paddle 94 to rotate around the axis of the rotating rod 8 through the connecting piece 92, so as to shear and mix the material in the stirring tank 1. During the stirring process, the magnetic attraction between the magnet on the inner side of the connecting piece 92 and the magnetic plug 93 can counteract the displacement caused by the centrifugal force, while the fixing rod 95 that passes through the connecting piece 92 and the magnetic plug 93 provides mechanical locking to prevent the stirring paddle 94 from accidentally falling off.

[0030] When it is necessary to disassemble the stirring assembly 9, the operator can enter the interior through the maintenance door 10 on the outside of the stirring tank 1, pull out the fixing rod 95 to release the constraint on the magnetic plug 93. At this time, the stirring paddle 94 will drive the magnetic plug 93 to disengage from the connector 92 under the action of gravity, completing the quick disassembly of a single stirring paddle 94. For the overall disassembly and assembly of the connecting end cover 3, press the pin 73 of the spring pin 7 to compress the spring 74 and drive the limiting rod 75 to disengage from the through hole of the clamping plate 5, releasing the lock on the clamping plate 5. Then the operator can lift the connecting end cover 3 to separate the clamping plate 5 from the positioning block 6, and then remove the motor 4, the rotating rod 8 and the remaining stirring assembly 9 from the fixing ring cover 2. During the disassembly process, the limiting baffle 72 ensures that the spring 74 is always in an effective compressed state by limiting the stroke of the limiting rod 75, preventing the pin 73 from completely disengaging from the fixing seat 71.

[0031] After cleaning or maintenance, when reinstalling, align the locking plate 5 of the connecting end cover 3 with the positioning block 6 of the fixing ring cover 2 and press it down. At this time, the pin 73 of the spring pin 7 is inserted into the through hole of the locking plate 5 under the action of the spring 74 to complete the locking. The stirring paddle 94 is quickly aligned with the magnetic attraction of the connecting piece 92 through the magnetic attraction of the magnetic plug 93. After inserting the fixing rod 95, it can resume operation. The material after stirring is discharged through the bottom feed pump 11, and the support frame 12 maintains the overall stability of the device.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
