Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
A liquid preparation mixing and stirring apparatus as shown in fig. 1 to 4, comprising a mixing tank 101 and a stirrer provided in the mixing tank;
the stirrer comprises a motor 103, a central stirring mechanism and an edge stirring mechanism;
the central stirring mechanism comprises a central rod 104 and a central blade 105 mounted on the central rod 104, in the embodiment, the lower end of the central rod extends towards the bottom of the mixing kettle, the central blade is mounted at the lower end of the central rod, and the central rod and the central blade are located in the middle of the mixing kettle;
the edge stirring mechanism comprises a rotating frame 106 and edge blades 107 arranged on the rotating frame 106, wherein the edge blades 107 are provided with a plurality of pieces, all the edge blades are close to the side wall of the mixing kettle, and all the edge blades 107 are distributed at intervals around the circumference of a central blade 105;
the motor 103 is arranged to drive the central rod 104 and the rotating frame 106 in rotation.
In this embodiment, each of the edge blades 107 has a long sheet shape whose length direction is parallel to the length direction of the center bar.
In this embodiment, the central rod and the rotating frame are rotatably mounted in the mixing tank (e.g., via bearings), respectively, and the rotation axis of the central rod coincides with the rotation axis of the rotating frame, and all the edge blades are equally circumferentially spaced around the rotation axis of the central rod.
And this technical scheme can stir the raw materials that mix the marginal position that the cauldron is close to the lateral wall through setting up edge rabbling mechanism for the mixture is more even, in order to guarantee the quality of preparation.
The output shaft of the motor 103 is connected with the upper end of the central rod 104, so that the motor 103 drives the central rod 104 to rotate;
a transmission mechanism which drives the rotating frame 106 to rotate when the central rod 104 rotates is arranged between the central rod 104 and the rotating frame 106, and the transmission mechanism is an intermittent motion mechanism;
the intermittent motion mechanism is configured such that the rotating frame 106 is stopped when the center rod 104 rotates n consecutive turns and rotates 1 turn after the center rod 104 rotates n +1 turn;
because the raw material in the middle of the mixing kettle has larger aggregation, the raw material in the middle of the mixing kettle has higher stirring times and continuity requirements than the raw material at the edge of the side wall of the mixing kettle. This technical scheme makes central rabbling mechanism can work and edge rabbling mechanism work intermittently through adopting intermittent motion mechanism to accord with the stirring demand, can realize the stirring more rationally, need not edge rabbling mechanism continuous operation simultaneously, can save the power consumption use cost of motor and improve life.
The rotating frame 106 is provided with a cylinder 108, and the cylinder 108 is hollow outside the center rod 104 so that the center rod 104 can rotate relative to the cylinder 108;
