[0006] By adopting the above technical solution, the assembly and positioning of the driving source, the magnetic coupler, and the stirring mechanism are achieved through the cooperation between the upper positioning assembly and the lower positioning assembly. Then, the fastening and fixing of the above three components are achieved by cooperating with the fastening components and the fixed compression rods, thereby completing the assembly and fixing operation between the three components. This structure only requires a small number of fasteners to achieve the convenient installation of the above three components, which is labor-saving and low in production cost, thereby improving the production efficiency of the equipment.

[0007] Further, the upper positioning assembly includes a plurality of positioning columns fixed to the compression ring, a plurality of first upper positioning holes formed in the driving source and corresponding to the plurality of positioning columns, and a plurality of second upper positioning holes formed in the shell and corresponding to the plurality of positioning columns, the positioning columns extending into the first upper positioning holes and the second upper positioning holes and fitting therewith.

[0009] Further, the lower positioning assembly includes a plurality of first lower positioning holes formed in the shell and corresponding to the plurality of fixed compression rods, and a plurality of second lower positioning holes formed in the stirring tank and corresponding to the plurality of fixed compression rods, the fixed compression rods sequentially passing through the first lower positioning holes and the second lower positioning holes and fitting therewith.

[0010] By using the above technical solution, the fixed compression rods sequentially pass through the first lower positioning holes and the second lower positioning holes to realize the positioning assembly of the compression ring, the shell and the stirring tank, which is simple in structure, convenient in assembly and low in workload.

[0011] Further, the fastening assembly includes a bearing block connected to the fixed compression rod and located on one side of the stirring tank, a fastening groove formed between the bearing block and the stirring tank, a locking plug inserted into the fastening groove for driving the compression ring, the shell and the stirring tank to move towards each other, and a fastener driving the locking plug to be inserted into the fastening groove.

[0012] By using the above technical solution, the fastener drives the locking plug to be inserted into the fastening groove to press the compression ring, the shell and the stirring tank towards each other to achieve the fastening purpose.

[0013] Further, the fastening groove is gradually tapered in the insertion direction of the locking plug to form a guide slope, and the locking plug is provided with a matching slope matching the guide slope.

[0014] By using the above technical solution, the matching between the guide slope and the matching slope changes the direction of the force, so as to achieve the fastening purpose.

[0015] Further, the magnetic coupler further includes an upper magnetic disk driven by the driving source, a transmission shaft connected to the stirring mechanism, a lower magnetic disk provided on the transmission shaft and corresponding to one side of the upper magnetic disk, and an isolation sleeve located between the upper magnetic disk and the lower magnetic disk, the isolation sleeve being clamped and fixed by the shell and the stirring tank.
