Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel stirring device with a cutting blade. Background Technology

[0002] In many fields such as chemical engineering, pharmaceuticals, and food processing, reaction vessels are the core equipment for realizing material mixing and reaction processes. As a key component of the reaction vessel, the structural design of the stirring device has a crucial impact on the mixing effect, reaction efficiency, and product quality.

[0003] Traditional reactor stirring devices typically consist of only a stirring shaft and stirring blades. The stirring blades mainly serve to stir and mix the materials. However, in actual production processes, some materials may have problems such as agglomeration or fibrous material entanglement. These problems not only affect the uniform mixing of materials but may also increase the operating resistance of the stirring device or even damage the stirring device, thereby affecting production efficiency and product quality. Utility Model Content

[0004] To address the issues that may arise in actual production processes, such as material clumping or fibrous entanglement, which can affect the uniform mixing of materials, increase the operating resistance of the stirring device, or even damage the stirring device, thereby impacting production efficiency and product quality, this invention provides a reactor stirring device with a cutting blade.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] An embodiment of this utility model provides a reactor stirring device with a cutting blade, comprising:

[0007] The mixing device body includes a mixing shaft, and a plurality of mixing blades are arranged circumferentially on the mixing shaft. Each mixing blade includes a cutting blade and a guide plate. The mixing shaft, the guide plate and the cutting blade are connected in sequence. The guide plate is inclined upward relative to the rotation direction of the mixing shaft, and the cutting direction of the cutting blade is in the same direction as the rotation direction of the mixing shaft.

[0008] According to some embodiments of this utility model, the cutting blade and the guide plate are detachably connected.

[0009] According to some embodiments of the present invention, the guide plate is provided with a sliding groove, and the cutting blade includes a connecting part that can be slidably connected with the sliding groove. The length direction of the sliding groove is parallel to the cutting direction of the cutting blade. One end of the sliding groove is open and the other end is closed. When the stirring shaft rotates, the closed end of the sliding groove can abut against the connecting part.

[0010] According to some embodiments of the present invention, the reactor stirring device with a cutting blade further includes a fixing structure for fixing the cutting blade and the guide plate.

[0011] According to some embodiments of the present invention, the fixing structure includes a pin and an elastic element. The pin is movably connected to the guide plate, and when the connecting part slides into the sliding groove, the pin can pass through the guide plate and be inserted into the connecting part. The elastic element is used to apply an elastic force to the pin so that the pin remains inserted into the connecting part.

[0012] According to some embodiments of the present invention, a sealing ring is also provided at the connection between the pin and the guide plate.

[0013] According to some embodiments of the present invention, the guide plate is provided with reinforcing ribs, which are arranged along the length direction of the guide plate.

[0014] This invention has at least the following beneficial effects: Firstly, the cutting blades on the stirring blades can precisely cut clumps or fibrous materials into smaller particles, thus solving the problems of material clumping and fiber entanglement. This avoids the increased stirring resistance and risk of damage to the stirring device caused by these problems, significantly improving the service life and operational stability of the stirring device. Secondly, the inclined design of the guide plate allows the material to form a "bottom-in, top-out" circulating flow pattern during stirring, greatly enhancing the material flow rate and mixing effect, achieving thorough mixing of materials within the reactor, and thus significantly improving reaction efficiency and product quality.

[0022] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0023] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intermediary element (e.g., the third element) between the element and the other element.

[0025] An embodiment of this utility model provides a reactor stirring device with a cutting blade, comprising:

[0026] The mixing device body 100 includes a mixing shaft 110. The mixing shaft 110 is circumferentially spaced with a plurality of mixing blades 120. Each mixing blade 120 includes a cutting blade 130 and a guide plate 140. The mixing shaft 110, the guide plate 140 and the cutting blade 130 are connected. The guide plate 140 is inclined upward relative to the rotation direction of the mixing shaft 110. The cutting direction of the cutting blade 130 is in the same direction as the rotation direction of the mixing shaft 110.

[0027] The stirring shaft 110 connects to the stirring blades 120 and transmits power. The cutting blade 130, part of the stirring blades 120, is used to cut lumps or fibrous materials in the material. The cutting direction of the cutting blade 130 is the same as the rotation direction of the stirring shaft 110, ensuring that the material is effectively cut during mixing. The guide plate 140, another part of the stirring blades 120, guides the material flow. The guide plate 140 is connected to the stirring shaft 110 and is inclined upwards relative to the rotation direction of the stirring shaft 110. The inclined design of the guide plate 140 pushes the material upwards axially, forming a "bottom-in, top-out" circulating flow, ensuring thorough mixing of the material in the reactor. This inclined design increases the material flow rate and mixing effect. The cutting blade 130 effectively cuts lumps or fibrous materials in the material, making the material more uniform. The inclined design of the guide plate 140 guides the material flow, increasing the mixing speed.

[0028] The working principle of this utility model is as follows:

[0029] When the stirring shaft 110 rotates, the stirring blades 120 rotate accordingly. Since the cutting direction of the cutting blade 130 is the same as the rotation direction of the stirring shaft 110, the material is cut into smaller particles by the cutting blade 130 during the stirring process, thereby preventing clumping. At the same time, the inclined design of the guide plate 140 can guide the material to flow upward, further improving the stirring effect and mixing efficiency.

[0030] In some embodiments, two layers of stirring blades 120 are arranged along the stirring shaft 110 axially, wherein adjacent layers of blades can be staggered; adjacent layers of guide plates 140 are inclined in opposite directions (e.g., the upper layer faces upward and the lower layer faces downward), forming a "bidirectional circulating flow" to further improve mixing efficiency.

[0031] In some embodiments, the cutting blade 130 and the guide plate 140 are detachably connected.

[0032] In practical use, the cutting blade 130 may wear out or be damaged due to prolonged use, requiring replacement. If the cutting blade 130 and guide plate 140 are an integral design, replacing the cutting blade 130 would necessitate replacing the entire stirring blade 120, increasing costs and maintenance time. By designing a detachable connection between the cutting blade 130 and guide plate 140, the cutting blade 130 can be easily replaced without replacing the entire stirring blade 120. Detachable connections can be achieved in various ways, such as threaded connections, snap-fit ​​connections, or bolted connections. These connection methods ensure both a secure connection and ease of disassembly and replacement. The detachable design makes replacing the cutting blade 130 more convenient, reducing maintenance time and costs. Since the guide plate 140 is generally not easily damaged, the detachable design extends the overall service life of the stirring device.

[0033] Furthermore, the guide plate 140 is provided with a sliding groove 141, and the cutting blade 130 includes a connecting part 131 that can be slidably connected with the sliding groove 141. The length direction of the sliding groove 141 is parallel to the cutting direction of the cutting blade 130. One end of the sliding groove 141 is open and the other end is closed. When the stirring shaft 110 rotates, the closed end of the sliding groove 141 can abut against the connecting part 131.

[0034] The guide plate 140 is provided with a sliding groove 141, the length of which is parallel to the cutting direction of the cutter 130. One end of the sliding groove 141 is open, and the other end is closed. The connecting part 131 of the cutter 130 cooperates with the sliding groove 141, and is installed on the guide plate 140 by a sliding connection. When the stirring shaft 110 rotates, the closed end of the sliding groove 141 can abut against the connecting part 131, thereby preventing the cutter 130 from loosening or shifting during stirring. The sliding connection design makes the installation and replacement of the cutter 130 simpler and faster; simply insert the connecting part 131 into the sliding groove 141. The closed end of the sliding groove 141 abuts against the connecting part 131, ensuring that the cutter 130 remains stable during stirring and will not loosen due to centrifugal force or material impact. When the stirring shaft 110 rotates, the cutter 130 remains stable under the abutment of the closed end of the sliding groove 141, ensuring that the cutter 130 can effectively cut lumps or fibrous materials in the material. When it is necessary to replace the cutting blade 130, simply slide the cutting blade 130 out along the direction of the sliding groove 141. The operation is simple and quick.

[0035] Furthermore, the reactor stirring device with the cutting blade 130 also includes a fixing structure 150 for fixing the cutting blade 130 and the guide plate 140.

[0036] Although the design of the sliding groove 141 and the connecting part 131 is sufficient for the installation and initial fixation of the cutting blade 130, in actual use, the cutting blade 130 may be subjected to significant centrifugal force. The fixing structure 150 is used to further secure the connection between the cutting blade 130 and the guide plate 140, ensuring that the cutting blade 130 will not loosen or shift during mixing. The fixing structure 150 can take various forms, such as bolts, screws, clips, or locking devices. These fixing structures 150 can be used in conjunction with the sliding groove 141 and the connecting part 131 to further enhance the stability of the cutting blade 130. The fixing structure 150 effectively prevents the cutting blade 130 from loosening or shifting due to centrifugal force or material impact during mixing, ensuring the stability and reliability of the cutting blade 130. Through the fixing structure 150, the cutting blade 130 is more secure during mixing, reducing safety hazards caused by the cutting blade 130 loosening.

[0037] Furthermore, the fixing structure 150 includes a pin 151 and an elastic member 152. The pin 151 is movably connected to the guide plate 140, and when the connecting part 131 slides into the sliding groove 141, the pin 151 can pass through the guide plate 140 and be inserted into the connecting part 131. The elastic member 152 is used to apply an elastic force to the pin 151 so that the pin 151 is kept inserted into the connecting part 131.

[0038] The pin 151 is movably connected to the guide plate 140. When the connecting part 131 of the cutter 130 slides into the sliding groove 141, the pin 151 can pass through the guide plate 140 and insert into the connecting part 131, thereby further fixing the cutter 130. An elastic element 152 (such as a spring) applies an elastic force to the pin 151, ensuring that the pin 151 remains stable after insertion into the connecting part 131, preventing loosening due to vibration or impact. When the connecting part 131 of the cutter 130 slides into the sliding groove 141, the pin 151 automatically inserts into the hole of the connecting part 131 under the action of the elastic element 152, thereby firmly fixing the cutter 130 to the guide plate 140. During stirring, the elastic force of the elastic element 152 can offset some of the vibration and impact forces, ensuring that the pin 151 will not loosen. When it is necessary to disassemble the cutter 130, simply pull out the pin 151 to disassemble the cutter 130.

[0039] Furthermore, a sealing ring is provided at the connection between the pin 151 and the guide plate 140.

[0040] During the use of the reactor stirring device, materials may leak through the connection between the pin 151 and the guide plate 140, especially when handling liquid or semi-fluid materials. Therefore, it is necessary to further enhance the sealing of the connection to prevent material leakage. A sealing ring is installed at the connection between the pin 151 and the guide plate 140. The sealing ring effectively prevents material leakage and ensures the equipment's airtightness. The sealing ring can be made of corrosion-resistant and high-temperature-resistant materials, such as rubber or polytetrafluoroethylene (PTFE), to adapt to different reaction conditions. The sealing ring can be installed at the connection between the pin 151 and the guide plate 140.

[0041] In some embodiments, the guide plate 140 is provided with reinforcing ribs 142, which are arranged along the length direction of the guide plate 140.

[0042] The guide plate 140 needs to withstand significant forces during the mixing process, especially when handling high-viscosity or high-density materials, which may cause deformation or damage. Therefore, it is necessary to further enhance the structural strength of the guide plate 140. Reinforcing ribs 142 are provided on the guide plate 140, with the ribs 142 arranged along the length of the guide plate 140, which can effectively enhance the bending resistance and overall structural strength of the guide plate 140. The reinforcing ribs 142 can be made of the same material as the guide plate 140, or a higher-strength material, such as high-strength steel or composite materials, can be selected. The reinforcing ribs 142 can be integrally formed with the guide plate 140, or fixed to the guide plate 140 by welding, bolting, or other methods.

Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
