Description

Technical Field

[0001] This utility model relates to the field of crystallizer stirring technology, and in particular to a crystallizer stirring device. Background Technology

[0002] In the crystallization process, the crystallizer stirring device is crucial for ensuring product quality and improving production efficiency. However, traditional devices have significant drawbacks in the discharge stage: the discharge control method is crude, relying solely on simple valve opening and closing, and cannot adjust the rate in real time according to the crystallization state. This can easily lead to insufficiently crystallized material flowing out when the discharge is too fast, affecting purity; or too slow, reducing efficiency and increasing energy consumption.

[0003] However, existing regulating devices have a simple structure, controlling speed only by changing the size of the discharge port, resulting in poor flexibility. When faced with changes in material viscosity or crystal particle size, it is difficult to balance rate and quality, easily leading to clogging or unevenness. Furthermore, the fixed and simple filter structure cannot be flexibly replaced to adapt to different processes, and it is independent of the discharge control, unable to work in conjunction with it. Therefore, a crystallizer stirring device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a crystallizer stirring device, which aims to improve the problem of the inflexibility of material discharge in traditional crystallizers in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A crystallizer stirring device includes a stirring tank, characterized in that: a discharge pipe is fixedly connected to the outside of the stirring tank, a plurality of support shafts are fixedly connected to the inside of the discharge pipe, one end of the plurality of support shafts is fixedly connected to the same support column, a plurality of fan blades are rotatably connected to the outside of the support column, a rotating head is rotatably connected to one end of each of the plurality of fan blades, a moving head is slidably connected to the outside of the rotating head, a common rotating sleeve is fixedly connected to one end of the plurality of moving heads, a handle is fixedly connected to the outside of the rotating sleeve, and a filter assembly for installing different filter components is provided inside the discharge pipe;

[0007] As a further description of the above technical solution:

[0008] The filter assembly includes multiple slots, which are formed inside the discharge pipe. Each slot has a locking block inside it, and the same filter screen is fixedly connected to the outside of each locking block.

[0009] As a further description of the above technical solution:

[0010] One end of each of the multiple fan blades is rotatably connected to the inside of the discharge pipe, and the discharge speed of the material is controlled by controlling the rotation angle of the fan blades;

[0011] As a further description of the above technical solution:

[0012] By pushing the handle, the rotation of multiple fan blades is affected;

[0013] As a further description of the above technical solution:

[0014] Multiple moving heads are slidably connected to the outside of the rotating head, and the rotating head is rotated by the influence of the moving heads;

[0015] As a further description of the above technical solution:

[0016] The shape of the card block is set to L-shape;

[0017] As a further description of the above technical solution:

[0018] The shape of the card block perfectly matches the card slot;

[0019] As a further description of the above technical solution:

[0020] The material is further subdivided by replacing the different filter screens.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the device controls the discharge rate by adjusting the fan blade angle. When the handle is pushed, the rotating sleeve drives the moving head to slide, causing the fan blades to rotate. A smaller fan blade angle results in a wider channel and faster discharge, while a larger angle results in a narrower channel and slower discharge. This adjustment mechanism can precisely control the discharge rate and adapt to different crystallization process requirements.

[0023] 2. In this utility model, the filter assembly uses a slot to fix a filter screen with an L-shaped locking block. When material flows through, it passes through the mesh, while large particles are intercepted. When the precision needs to be adjusted, filter screens of different mesh sizes can be replaced to ensure the purity of the output material without affecting other functions.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 2 This utility model provides an embodiment of a crystallizer stirring device, including a stirring tank 1, which serves as the core container for the crystallization process. A discharge pipe 2 is fixedly connected to the outside of the stirring tank 1, acting as a material discharge channel. Multiple support shafts 3 are fixedly connected inside the discharge pipe 2, providing support and fixation within the pipe. One end of each support shaft 3 is fixedly connected to a common support column 4. Multiple fan blades 5 are rotatably connected to the outside of the support column 4, adjusting the size of the material flow channel within the discharge pipe 2 by changing their rotation angle. A smaller angle results in a wider channel and faster discharge; a larger angle results in a narrower channel and slower discharge, thus achieving precise control of the discharge rate. These fan blades are the direct actuators for adjusting the discharge speed. One end of each fan blade 5 is rotatably connected inside the discharge pipe 2, controlling the material discharge speed by controlling the rotation angle of the fan blades 5.

[0033] Multiple fan blades 5 are rotatably connected to one end of a rotating head 6. The rotating head 6 is designed as the core support component for constructing the angle adjustment mechanism of the fan blades 5. A moving head 7 is slidably connected to the outside of the rotating head 6. The moving head 7 is designed as a bridge component for transmitting power and realizing motion conversion in the linkage structure. Multiple moving heads 7 are slidably connected to the outside of the rotating head 6. The rotating head 6 is rotated by influencing the rotation of the moving head 6. One end of multiple moving heads 7 is fixedly connected to the same rotating sleeve 8. The rotating sleeve 8 is designed as a bridge component for transmitting power and realizing motion conversion in the linkage structure. A handle 9 is fixedly connected to the outside of the rotating sleeve 8. The handle 9 is designed to make it convenient and feasible to manually intervene in the discharge rate. By pushing the handle 9, the rotation of multiple fan blades 5 is affected. The discharge pipe 2 has a filter assembly for installing different filter components inside.

[0034] Reference Figures 3 to 5 The filter assembly includes multiple slots 10. The slots 10 are designed as the basic structure for installing the filter assembly. The multiple slots 10 are opened inside the discharge pipe 2. Each slot 10 has a locking block 11 inside it. The locking block 11 is designed to facilitate installation and disassembly. The locking block 11 is L-shaped and its shape fits perfectly with the slot 10.

[0035] Multiple card blocks 11 are externally fixedly connected to the same filter screen 12. Here, the filter screen 12 is designed as the core component for filtration, using its mesh size to screen crystalline materials, intercepting large particles or crystals that do not meet particle size requirements, while allowing materials that meet the standards to pass through. By replacing the filter screen 12 with different mesh sizes, different needs for material subdivision can be met, improving the device's adaptability to material filtration precision. Different filter screens 12 can be used to subdivide the material.

[0036] Working Principle: The discharge rate of this crystallizer's stirring device is controlled primarily through the adjustment mechanism of the fan blade 5 angle. Inside the discharge pipe 2, one end of the fan blade 5 is rotatably connected to the inner wall of the discharge pipe 2, while the other end forms a linkage structure with the rotating head 6, the moving head 7, and the rotating sleeve 8. When the handle 9 is pushed, the rotating sleeve 8 drives the moving head 7 to slide outside the rotating head 6, causing the rotating head 6 to deflect, thereby changing the rotation angle of the fan blade 5. The angle of the fan blade 5 directly affects the material flow channel: a smaller angle results in a relatively open channel, less material obstruction, and a faster discharge speed; a larger angle narrows the channel, increases resistance to material flow, and slows down the discharge speed. The coordinated adjustment of the fan blade 5 angle enables precise control of the discharge rate of the crystallized material, adapting to the discharge requirements of different stages and material characteristics in the crystallization process.

[0037] The working principle of the crystallizer stirring device's filter assembly is as follows: Multiple slots 10 are opened inside the discharge pipe 2, serving as the mounting base for the filter components. The filter screen 12 is precisely fitted and locked in place with the slots 10 via L-shaped locking blocks 11 on its edge. When the crystalline material flows from the stirring tank 1 into the discharge pipe 2, the material first contacts the filter screen 12, and is screened using the through holes on the screen: material that meets the mesh size can pass through the screen and continue to be discharged along the discharge pipe 2; impurities and large crystal particles larger than the mesh size are intercepted. If the filtration accuracy needs to be adjusted, the detachable structure of the slots 10 and locking blocks 11 allows for the replacement of filter screens 12 with different mesh sizes to adapt to the finer particle size requirements of different crystallization processes, ensuring the purity of the crystals or solution in the discharge, while not affecting the coordinated operation of other functions such as discharge rate control.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
