Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a cutting and stirring mechanism based on a reaction kettle. Background Art

[0002] A reaction kettle is a container device used for carrying out chemical reactions, and is widely used in the fields of chemical industry, pharmaceuticals, food, scientific research, etc.

[0003] The stirring mechanism in the reaction kettle can stir the materials, but it basically has no cutting effect on the materials. When the materials added to the reaction kettle are agglomerated, the stirring mechanism usually cannot disperse the agglomerated materials, or it takes a long time to disperse the materials, which will have a negative impact on the mixing efficiency of the materials in the reaction kettle. Summary of the Utility Model

[0007] In addition, the preferred structure is that a hydraulic rod assembly is fixedly arranged on the top of the reaction kettle body, and the piston rod of the hydraulic rod assembly is vertically upward and connected to a support frame.

Detailed Embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Referring to Figures 1-6, A cutting and stirring mechanism based on a reaction kettle, including a reaction kettle body 1. A stirring shaft 2 is rotatably arranged inside the reaction kettle body 1. A plurality of stirring paddles 3 are installed on the stirring shaft 2, and a blade 4 is movably arranged at the bottom of the stirring paddle 3. A lower connecting ring 43 and an upper connecting ring 54 are sleeved on the stirring shaft 2. Horizontal columns 42 are fixedly arranged on both sides of the lower connecting ring 43. A plurality of columns 41 connected to the blade 4 are fixedly arranged at the bottom of the horizontal column 42. And the lower connecting ring 43 is connected to the upper connecting ring 54 through a clamping member 55. Among them, the stirring shaft 2 is driven to rotate by a driving motor at the top of the reaction kettle body 1. This is prior art and will not be elaborated here.

[0022] Among them, a hydraulic rod assembly 5 is fixedly arranged at the top of the reaction kettle body 1. The piston rod of the hydraulic rod assembly 5 is vertically upward and connected to the support frame 51. A plurality of connecting columns 52 are fixedly arranged vertically downward at the bottom of the support frame 51. The connecting columns 52 all extend into the interior of the reaction kettle body 1, and the bottom ends of the connecting columns 52 are fixedly connected to the upper connecting ring 54 through connecting rods 53. Through the settings of the support frame 51, the connecting columns 52 and the connecting rods 53, the upper connecting ring 54 can be connected to the piston rod of the hydraulic rod assembly 5, so that the height of the upper connecting ring 54 can be controlled by the hydraulic rod assembly 5. And a sealing ring is arranged at the hole where the connecting column 52 passes through the reaction kettle body 1 to ensure the sealing inside the reaction kettle body 1.

[0023] Among them, a clamping member 55 is fixedly arranged at the bottom of the upper connecting ring 54, and the clamping member 55 is adaptively inserted into a clamping cavity 431 opened at the top of the lower connecting ring 43. Through the adaptive clamping between the clamping member 55 and the cavity 431, the upper connecting ring 54 can be connected to the lower connecting ring 43. And it should be noted that the parts in contact between the clamping member 55 and the clamping cavity 431 are all made of smooth materials, so that the lower connecting ring 43 and the clamping cavity 431 can rotate on the clamping member 55. This enables the upper connecting ring 54 to drive the lower connecting ring 43 to move vertically, and the normal rotation of the lower connecting ring 43 will not affect the upper connecting ring 54. And both the lower connecting ring 43 and the upper connecting ring 54 are sleeved on the stirring shaft 2 but not fixedly connected to the stirring shaft 2.

[0024] Among them, blade cavities 31 are opened at the bottom of the stirring paddles 3, and the blade cavities 31 are all adapted to the blades 4. Three columns 41 are fixedly arranged vertically downward at the bottom of the horizontal column 42. The columns 41 all pass through the stirring paddle 3 and are fixedly connected to the blade 4. Through the settings of the columns 41 and the horizontal column 42, the blade 4 can be fixedly connected to the lower connecting ring 43, so that the blade 4 can be driven to move vertically by the vertical movement of the lower connecting ring 43.

[0025] In this embodiment, when the user only needs to stir the materials in the reactor body 1, the stirring shaft 2 can be controlled to rotate. At this time, the materials can be stirred by the rotation of the stirring paddle 3. At this time, the blades 4 are all located in the blade cavity 31 at the bottom of the stirring paddle 3, and the lower connecting ring 43 rotates synchronously with the stirring shaft 2 through the arrangement of the upright column 41.

[0026] The upper connecting ring 54 is located at the top of the lower connecting ring 43. Through the matching and clamping between the clamping member 55 and the clamping cavity 431, the upper connecting ring 54 and the lower connecting ring 43 can move vertically synchronously, and the rotation of the lower connecting ring 43 will not affect the upper connecting ring 54.

[0027] When the user needs to use the blade 4 to break up the materials in the reactor body 1, only need to control the piston rod of the hydraulic rod assembly 5 to contract downward, so as to drive the support frame 51, the connecting column 52, the connecting rod 53 and the upper connecting ring 54 to move downward synchronously. Thus, the lower connecting ring 43 can be driven to move downward synchronously through the movement of the upper connecting ring 54. At this time, the cross bar 42, the upright column 41 and the blade 4 can be driven to move downward synchronously through the movement of the lower connecting ring 43, so that the blade 4 can be moved below the stirring shaft 2, and thus the materials can be broken up by the blade 4.

[0028] When the use of the blade 4 is completed, only need to control the piston rod of the hydraulic rod assembly 5 to extend upward, and the blade 4 can be retracted into the blade cavity 31. And it should be noted that the upright column 41 only passes through the stirring paddle 3 and is not fixedly connected to the stirring paddle 3.

[0029] In this utility model, the stirring of the materials in the reactor body 1 can be realized through the stirring paddle 3. When encountering agglomerated materials, the upper connecting ring 54 and the lower connecting ring 43 can be driven to move downward synchronously through the hydraulic rod assembly 5, so that the blade 4 can be taken out of the blade cavity 31, and thus the agglomerated materials can be broken up by the blade 4 to improve the mixing efficiency of the materials in the reactor body 1.

[0030] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacement or change, and should be covered within the protection scope of the present utility model.
