Therefore, precipitation stirring devices are common equipment in the preparation of calcium stearate.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0029] In some embodiments, please refer to the accompanying drawings. Figures 1-7 A bidirectional stirring sedimentation stirring device includes a stirring tank 2 and a stirring tank cover 3 disposed on the upper end of the stirring tank 2; it also includes an inclined support module 1, a stirring module 4 and a support plate 5;
[0030] The inclined support module 1 is symmetrically installed at both ends of the mixing tank 2 to support the mixing tank 2 and tilt the mixing tank 2. A support plate 5 is fixedly connected to the mixing tank cover 3.
[0031] The stirring module 4 includes a bidirectional stirring mechanism 41 and a vertical moving mechanism 42. The bidirectional stirring mechanism 41 passes through the stirring tank cover 3 and is installed on the upper and lower sides of the stirring tank cover 3. The bidirectional stirring mechanism 41 is used to synchronously rotate the stirring tank 2 in opposite directions. The vertical moving mechanism 42 is set on the bidirectional stirring mechanism 41 and is used to stir the solution in the stirring tank 2 vertically.
[0032] In this invention, the reactants are moved into the stirring tank 2, and the stirring tank 2 is simultaneously stirred in opposite directions by the bidirectional stirring mechanism 41. At the same time, the bidirectional stirring mechanism 41 drives the up-and-down moving mechanism 42, so that the solution in the stirring tank 2 is stirred up and down until the reaction is completed. The operator turns off the bidirectional stirring mechanism 41, removes the solution from the stirring tank 2, and tilts the stirring tank 2 by the tilting support module 1 so that the opening of the tank is tilted, and cleans the stirring tank 2, stirring tank cover 3 and stirring module 4.
[0033] In this invention, the bidirectional stirring mechanism 41 and the up-and-down moving mechanism 42 work together to simultaneously stir the solution in the stirring tank 2 in opposite directions while stirring the solution up and down, which helps to prevent the accumulation of precipitates and make the reaction more complete; the tilting support module 1 is used to tilt the stirring tank 2, which makes it easier to clean the stirring tank 2.

The inner stirring shaft 412 passes through the mixing tank cover 3, and the lower end of the inner stirring shaft 412 is fixedly connected to the inner stirring blade 415. The inner stirring blade 415 is located on the lower side of the mixing tank cover 3. The middle part of the inner stirring shaft 412 is slidably connected to the outer stirring shaft 413. The outer stirring shaft 413 passes through the mixing tank cover 3 and is rotatably connected to the mixing tank cover 3. The lower end of the outer stirring shaft 413 is fixedly connected to the outer stirring frame 414. The outer stirring frame 414 is located on the lower side of the mixing tank cover 3. The bidirectional drive assembly 411 is connected to the inner stirring shaft 412 and the outer stirring shaft 413, and is also connected to the support plate 5. The bidirectional drive assembly 411 is used to drive the inner stirring shaft 412, the outer stirring shaft 413, and the connecting rod 422.
[0036] The bidirectional drive assembly 411 includes a motor 4111, a rotating wheel 4112, a driven wheel 4113, a transmission belt 4114, a connecting block 4115, an upper driven gear 4116, a lower drive gear 4117, and a side driven gear 4118.

The driven wheel 4113 is connected to the connecting rod 422 via a spline on the front side of the plate 5. The lower end of the driven wheel 4113 is fixedly connected to one end of two symmetrical connecting blocks 4115. The other end of the two connecting blocks 4115 is fixedly connected to the upper driven gear 4116. The upper driven gear 4116 and the lower driving gear 4117 are placed symmetrically, and the upper driven gear 4116 and the lower driving gear 4117 are respectively meshed with the side driven gear 4118. The upper driven gear 4116 is connected to the inner stirring shaft 412 via a spline. The lower driving gear 4117 is fixedly connected to the outer stirring shaft 413. The side driven gear 4118 is rotatably connected to the support plate 5.
[0037] In this invention, the output shaft of the motor 4111 drives the rotating wheel 4112 to rotate. The rotating wheel 4112 drives the driven wheel 4113 to rotate via the transmission belt 4114. The driven wheel 4113 drives the connecting block 4115 and the upper driven gear 4116 to rotate. The upper driven gear 4116 meshes with the side driven gear 4118 to rotate, thereby driving the lower drive gear 4117 to rotate. At this time, the upper driven gear 4116 and the lower drive gear 4117 rotate in opposite directions. 4117 drives the outer stirring shaft 413 and the outer stirring frame 414 to start rotating. At the same time, the driven wheel 4113 drives the connecting rod 422 to rotate. Since the connecting rod 422 is sleeved on the reciprocating screw 421, the connecting rod 422 moves up and down while rotating. The connecting rod 422 drives the inner stirring shaft 412 to move up and down while rotating. The inner stirring shaft 412 drives the inner stirring blade 415 to rotate and move up and down at the same time. At this time, the inner stirring blade 415 and the outer stirring frame 414 rotate in opposite directions.
[0038] In this invention, the inner stirring blade 415 and the outer stirring frame 414 stir in opposite directions, making the stirring more thorough. Furthermore, the up-and-down movement of the inner stirring blade 415 better stirs the precipitate into the solution, resulting in a more complete reaction.
[0039] like Figure 1 , Figure 2 and Figure 5As shown, the tilting support module 1 includes a limiting mechanism 11, a bracket 12, a push cylinder 13, and a stop block 14; the limiting mechanism 11 is provided at one end of the mixing tank 2, and the limiting mechanism 11 is used to limit the tilt of the mixing tank 2.

[0040] The limiting mechanism 11 includes a limiting block 111 and a fixing block 113; one end of the mixing tank 2 is fixedly connected to the fixing block 113, the fixing block 113 is rotatably connected to the bracket 12, the fixing block 113 has a limiting groove 112, the limiting block 111 is fixedly connected to the bracket 12, and the limiting block 111 is inserted into the limiting groove 112.
[0041] In this invention, after the operator removes the solution from the mixing tank 2, the operator activates the push cylinder 13. Since the fixing block 113 is rotatably connected to the bracket 12, under the action of the push cylinder 13, the stop block 14, the fixing block 113, the mixing tank 2, the mixing tank cover 3, the mixing module 4, and the support plate 5 begin to rotate and tilt until the limiting block 111 contacts the inner wall of the limiting groove 112, stopping the tilt. The operator then removes the mixing tank cover 3, the mixing module 4, and the support plate 5 to clean the device. After cleaning, the device is reset.
[0042] In this utility model, the limiting block 111, the limiting groove 112 and the push cylinder 13 enable the mixing tank 2 to tilt within a certain range, making it convenient to clean the mixing tank 2.
