Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agitator technology, specifically relating to a glass-lined nine-blade agitator. Background Technology
[0002] Glass-lined equipment is made by firing at a high temperature of around 900℃, causing corrosion-resistant glass material to adhere tightly to the metal surface. It possesses excellent corrosion resistance, a smooth and wear-resistant surface, and a certain degree of thermal stability. It is widely used in chemical, metallurgical, rubber and plastics, and petroleum industries. The corrosion resistance of glass-lined agitators is superior to that of stainless steel, capable of withstanding corrosion from various concentrations of inorganic acids, organic acids, organic solvents, and weak alkalis (except for hydrofluoric acid containing fluoride ions, concentrated phosphorus at temperatures above 150℃, and strong alkalis). It is a commonly used corrosion-resistant material in chemical production. Most existing modular glass-lined agitators are integrated, consisting of one or two different blades. When encountering mixing tanks of different depths, it is necessary to replace the agitator with one of different lengths, which is complex, troublesome, time-consuming, and labor-intensive. Furthermore, existing agitators cannot be matched with different agitator blades according to the existing mixing efficiency, reducing their practicality.
[0003] Therefore, a combined glass-lined agitator, with announcement number "CN219559369U", includes a mixing tank body. A rotating shaft is fixedly installed inside the mixing tank body. An impeller-type blade is fixedly installed on the outer wall of the rotating shaft. A paddle-type blade is fixedly installed on the lower outer surface of the rotating shaft. Another impeller-type blade is fixedly installed on the lower outer surface of the paddle-type blade. A fixing assembly is fixedly installed between the rotating shaft and the paddle-type blades. The fixing assembly includes a threaded hole, a sealing gasket, and a reverse bolt. Through this fixing assembly, multiple blades of different types can be quickly combined and fixed together. The length of the agitator can also be lengthened or shortened according to the different depths of the mixing tank. Furthermore, different agitator blades can be combined to improve mixing efficiency, thereby enhancing the practicality and flexibility of the agitator and leading to better application prospects.
[0004] However, for the aforementioned combined glass-lined agitator, although the length of the agitator can be increased or decreased by aligning the second reverse bolt with the threaded hole at the bottom of the first connecting rod according to the different depths of the agitator tank, and by connecting the second reverse bolt with the first connecting rod with a thread, and by matching different agitator blades, the following obvious defects still exist in the use process: the agitator blade and the agitator shaft are an integral structure, and there is no disassembly and assembly structure between the individual agitator blade and the agitator shaft. This means that if one of the agitator blades on the agitator shaft is damaged, the entire agitator needs to be replaced, and it is not possible to disassemble and replace a single damaged agitator blade. Utility Model Content
[0005] The purpose of this invention is to provide a glass-lined nine-blade stirrer to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a glass-lined nine-blade stirrer, comprising:
[0007] The stirring spindle has blade mounting limit sleeve A and blade mounting limit sleeve B, which are respectively fitted on the stirring spindle through a combination of spacer sleeves to increase or decrease the number of stirring blades. The end of the blade mounting limit sleeve B is provided with a blade fixing pressure sleeve that is fitted on the stirring spindle to limit and press the blade mounting limit sleeve B.
[0008] A connecting lock cover is threadedly locked to the top of the stirring spindle. The locking of the connecting lock cover causes the blade fixing sleeve to move up and down on the stirring spindle, pressing one end of the stirring blade into the blade mounting limit sleeve A and the blade mounting limit sleeve B. The stirring blades that make up the nine-blade stirrer are installed in the concave cavities at the ends of the blade mounting limit sleeve A and the blade mounting limit sleeve B.
[0009] Preferably, one end of the stirring blade is provided with an installation limiting block, and one end of the installation limiting block is provided with an arc-shaped assembly block to ensure that the stirring blade can be accurately positioned during installation, avoiding shaking or displacement, thereby ensuring the stability and efficiency of stirring. Operators can more easily connect it with other components, effectively improving work efficiency, while also reducing damage to the equipment caused by rigid installation.
[0010] Preferably, both the blade mounting limiting sleeve A and the blade mounting limiting sleeve B have mounting limiting grooves at their ends to limit the assembly of the mounting block on the stirring blade, and the inner outer wall of the mounting limiting groove has evenly provided limiting grooves to allow the mounting limiting block to slide into the limiting position. The limiting grooves perfectly fit the mounting limiting blocks on the stirring blade, further enhancing the stability of the stirring blade after installation and preventing loosening or displacement during the stirring process.
[0011] Preferably, four stirring blades are mounted on the blade mounting limiting sleeve A, and five stirring blades are mounted on the blade mounting limiting sleeve B. The number of stirring blades mounted on the blade mounting limiting sleeve A and the blade mounting limiting sleeve B constitutes a nine-blade stirring shaft. During the stirring process, the stirring blades at different positions can work together to stir the material in all directions and at multiple angles, avoiding the occurrence of stirring dead zones, thereby improving the stirring quality and efficiency.
[0012] Preferably, the combined spacer sleeve is disposed between the stirring blades installed on the blade mounting limiting sleeve A and the blade mounting limiting sleeve B, and the bottom end of the combined spacer sleeve extends downward to provide a lower pressure ring A that is inserted into the assembly limiting groove of the blade mounting limiting sleeve A to press and fix the assembly block. The lower pressure ring A further enhances the firmness of the stirring blade installation and prevents the stirring blades from loosening when rotating at high speed.
[0013] Preferably, the bottom end of the blade fixing sleeve extends downward to provide a pressing ring B, which is inserted into the assembly limiting groove in the blade mounting limiting sleeve B to press down the assembly block and press the blade mounting limiting sleeve B tightly against the top of the combined spacer sleeve. On the one hand, this firmly presses the stirring blade to ensure its stability during operation; on the other hand, it tightly connects the blade mounting limiting sleeve B with the combined spacer sleeve, making the structure of the entire stirrer more stable and effectively preventing loosening and displacement between components.
[0014] Preferably, a hidden bolt is provided through the center of the end of the connecting lock cover, and the hidden bolt is locked to the end of the stirring main shaft. The locking of the connecting lock cover causes the lower end of the blade fixing sleeve to be pressed into the end of the blade installation limiting sleeve B. The locking operation of the connecting lock cover can conveniently realize the pressing of the blade fixing sleeve, thereby quickly completing the installation and fixing of the stirring blade.
[0015] Preferably, the connecting locking cover has evenly spaced connecting locking holes around its end edge that are combined with and locked to the stirrer drive component, ensuring stable power transmission and enabling the stirrer to operate efficiently. Simultaneously, the evenly distributed design ensures the balance of the connection, preventing equipment damage or poor stirring effect caused by uneven force.
[0016] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This glass-lined nine-blade stirrer...
[0017] This utility model discloses a nine-blade glass-lined agitator. The agitator blades and the main shaft are not integrally structured; instead, they are fixed together using components such as blade mounting limit sleeve A, blade mounting limit sleeve B, and blade fixing sleeve. When a blade is damaged, the operator simply loosens the connecting lock cover, allowing the blade fixing sleeve to move upwards, and easily removes the damaged blade from the mounting limit groove for replacement. Unlike existing technologies that require replacing the entire agitator, this significantly reduces maintenance and time costs, and improves equipment efficiency.
[0018] This invention features a unique nine-blade stirring shaft design. Four stirring blades are mounted on blade mounting limit sleeve A, and five are mounted on blade mounting limit sleeve B. During the stirring process, the stirring blades at different positions work together to stir the material from all directions and multiple angles. This avoids the occurrence of stirring dead zones, making the material more evenly stirred, greatly improving the stirring quality, and meeting the needs of various industrial production processes with high requirements for stirring uniformity.
[0019] The blade mounting limit sleeve A and blade mounting limit sleeve B on the mixing shaft of this invention can be disassembled and reassembled via combined spacer sleeves, thereby increasing or decreasing the number of mixing blades. This allows the mixer to flexibly adjust the configuration of the mixing blades according to different mixing tasks and the specific conditions of the mixing tank. Whether dealing with mixing tanks of different depths or materials of different properties and mixing difficulties, the optimal mixing effect can be achieved by adjusting the number and layout of the blades. It is highly versatile and effectively improves the practicality and flexibility of the mixer. Attached Figure Description

[0026] 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.
[0027] Please see Figure 1-5 This utility model provides a technical solution: a glass-lined nine-blade stirrer, comprising:
[0028] The mixing spindle 1, as the core support component of the entire mixer, is forged from high-strength alloy steel, possessing excellent bending and torsional resistance, and can operate stably under high-speed rotation and complex working conditions. Its surface is treated with fine glass enamel, which not only effectively prevents chemical corrosion but also improves surface smoothness, reducing material adhesion and resistance. The mixing spindle 1 is fitted with blade installation limit sleeves A3 and B4, which are used to add or remove mixing blades, through combined spacer sleeves 2. The combined spacer sleeves 2 are made of high-quality engineering plastics, which have good insulation, corrosion resistance, and a certain degree of flexibility. Its internal design has a smooth inner hole that perfectly matches the stirring spindle 1, ensuring that it can be easily fitted onto the spindle. The end of the blade mounting limit sleeve B4 is provided with a blade fixing pressure sleeve 5 that fits onto the stirring spindle 1 to limit and press the blade mounting limit sleeve B4. The bottom of the stirring spindle 1 is provided with a stop block for blocking the blade mounting limit sleeve A3. At the bottom of the stirring spindle 1, a sturdy stop block is carefully set. This stop block is made of the same material as the spindle and is firmly connected by a special welding process. It is used to accurately block the blade mounting limit sleeve A3, ensuring that its position is fixed during operation and that no axial displacement occurs.
[0029] The connecting cover 6 is threadedly locked to the top of the stirring shaft 1. The connecting cover 6 is made of high-strength alloy material and undergoes a special heat treatment process, giving it excellent strength and toughness. Its internal design features an internal thread that matches the stirring shaft 1, allowing it to be tightly threaded onto the top of the stirring shaft 1 through rotation. The locking of the connecting cover 6 causes the blade fixing sleeve 5 to move up and down on the stirring shaft 1, pressing one end of the stirring blade into the blade mounting limit sleeve A3 and blade mounting limit sleeve B4. The cavities at the ends of blade mounting limit sleeves A3 and B4 each house the stirring blades 7, which form the nine-blade stirrer. The stirring blades 7 are key components that directly act on the materials for stirring. They are made of a special enameled material, possessing good chemical stability, resisting the erosion of various corrosive materials, and also having a certain degree of strength and toughness. Both blade mounting limit sleeves A3 and B4 are made of high-strength and corrosion-resistant stainless steel, manufactured using precision machining processes. Their outer surfaces are designed with special anti-slip textures to facilitate better gripping and operation during installation and disassembly. The end cavities are precisely sized for mounting the stirring blades 7, ensuring a tight fit.
[0030] This also reduces damage to the equipment caused by rigid installation. Four stirring blades 7 are mounted on the blade mounting limit sleeve A3, and five stirring blades 7 are mounted on the blade mounting limit sleeve B4. Together they form a nine-blade stirring shaft. During the stirring process, the stirring blades 7 at different positions can work together to stir the material in all directions and at multiple angles, avoiding the occurrence of stirring dead zones.
[0031] One end of the stirring blade 7 is provided with an installation limiting block 8. The installation limiting block 8 is manufactured using a process that integrates it with the blade to ensure a firm connection. Furthermore, one end of the installation limiting block 8 is provided with an arc-shaped assembly block 9. This unique arc design not only makes it easy for the stirring blade 7 to be aligned with the assembly limiting groove 10 during installation, achieving precise positioning and preventing shaking or offset, thus ensuring the stability and efficiency of stirring, but also makes it easier for operators to connect it with other components, effectively improving work efficiency.
[0032] Both blade mounting limiting sleeve A3 and blade mounting limiting sleeve B4 have mounting limiting grooves 10 at their ends to limit the assembly of the mounting block 9 on the stirring blade 7. The inner outer wall of the mounting limiting groove 10 is evenly provided with limiting grooves 11 to allow the mounting limiting block 8 to slide into the limiting position. The shape and size of the limiting groove 11 are highly matched with the mounting limiting block 8 on the stirring blade 7, which can ensure that the stirring blade 7 will not loosen or shift after installation, greatly improving the stability of stirring.
[0033] Four stirring blades 7 are mounted on the blade mounting limit sleeve A3, and five stirring blades 7 are mounted on the blade mounting limit sleeve B4. The number of stirring blades 7 mounted on the blade mounting limit sleeve A3 and the blade mounting limit sleeve B4 constitutes a nine-blade stirring shaft.
[0034] The combined spacer sleeve 2 is positioned between the agitator blades 7 mounted on the blade mounting limiting sleeve A3 and the blade mounting limiting sleeve B4. The bottom end of the combined spacer sleeve 2 extends downwards and features a pressing ring A12 that inserts into the assembly limiting groove 10 of the blade mounting limiting sleeve A3 to press and fix the assembly block 9. The combined spacer sleeve 2 has a smooth inner hole that perfectly matches the agitator shaft 1, ensuring easy fitting onto the shaft without generating additional friction or noise during rotation. The unique pressing ring A12 extending downwards from the bottom end of the combined spacer sleeve 2 precisely matches the assembly limiting groove 10, allowing it to be tightly inserted into the assembly limiting groove 10 of the blade mounting limiting sleeve A3, firmly pressing and fixing the assembly block 9, effectively enhancing the stability of the agitator blades 7 installation.
[0035] The blade fixing sleeve 5 has a downward-extending pressing ring B13 at its bottom end. The pressing ring B13 is inserted into the assembly limiting groove 10 in the blade mounting limiting sleeve B4 to press down on the assembly block 9 and to press the blade mounting limiting sleeve B4 tightly against the top of the combined spacer sleeve 2. The blade fixing sleeve 5 is also made of stainless steel, which has good rigidity and wear resistance. Its interior is designed with a threaded hole that mates with the stirring shaft 1. Through the synergistic effect with the connecting lock cover 6, it achieves the limiting and pressing of the blade mounting limiting sleeve B4. The shape and size of the pressing ring B13 are carefully designed so that it can be accurately inserted into the assembly limiting groove 10 in the blade mounting limiting sleeve B4. On the one hand, it presses down on the assembly block 9 to ensure the stability of the stirring blade 7; on the other hand, it presses the blade mounting limiting sleeve B4 tightly against the top of the combined spacer sleeve 2, making the entire stirrer structure more compact and stable.
[0036] A hidden bolt 14 is installed at the center of the end of the connecting cover 6. The hidden bolt 14 is made of high-strength carbon steel and has been rust-proofed. By locking it to the end of the stirring shaft 1, the blade fixing sleeve 5 is pressed, making it convenient and quick to install and fix the stirring blade 7. Connecting locking holes 15 are evenly distributed around the end side. The hidden bolt 14 is locked to the end of the stirring shaft 1. The locking of the connecting cover 6 presses the lower end of the blade fixing sleeve 5 into the end of the blade installation limiting sleeve B4. Connecting locking holes 15 are evenly distributed around the end side of the connecting cover 6 to be combined and locked with the stirring drive component. The size and position of the connecting locking holes 15 are precisely calculated to ensure precise combination and locking with the stirring drive component, ensuring stable power transmission and efficient operation of the stirring unit. At the same time, the evenly distributed design ensures the balance of the connection and avoids equipment damage or poor stirring effect caused by uneven force.
[0037] Specifically, in use, first, the combined spacer sleeve 2 is fitted onto the stirring spindle 1, utilizing its smooth inner hole to perfectly fit the spindle, easily completing the fitting. Then, the blade mounting limiting sleeve A3 and blade mounting limiting sleeve B4 are respectively fitted onto the stirring spindle 1 through the combined spacer sleeve 2. The stop block at the bottom of the stirring spindle 1 precisely blocks the blade mounting limiting sleeve A3, preventing its axial displacement. Align the assembly block 9 of the stirring blade 7 with the assembly limiting groove 10 at the end of the blade mounting limiting sleeve A3 and blade mounting limiting sleeve B4, allowing the mounting limiting block 8 to slide into the limiting groove 11, achieving initial positioning of the stirring blade 7. Next, the blade fixing sleeve 5 is fitted onto the stirring spindle 1, positioning it at the end of the blade mounting limiting sleeve B4. Finally, the connecting lock cover 6 is locked to the top of the stirring spindle 1 by the internal thread. As the connecting lock cover 6 is locked, the hidden bolt 14 fixes it to the end of the stirring spindle 1. At the same time, the blade fixing sleeve 5 moves up and down on the stirring spindle 1. The pressing ring B13 is inserted into the assembly limiting groove 10 of the blade mounting limiting sleeve B4 and presses down on the assembly block 9, so that the blade mounting limiting sleeve B4 is pressed tightly on the top of the combined spacer sleeve 2, thus completing the firm installation of the stirring blade 7.
[0038] The connecting locking hole 15 on the side of the connecting lock cover 6 is precisely combined and locked with the agitator drive component. The drive component provides power to the agitator, driving the mixing spindle 1 to rotate at high speed. The mixing spindle 1 drives the blade mounting limit sleeve A3, the blade mounting limit sleeve B4, and the nine-blade agitator blade 7 mounted on them to rotate together. During the mixing process, the lower pressure ring A12 of the combined spacer sleeve 2 and the lower pressure ring B13 of the blade fixing pressure sleeve 5 respectively press and fix the assembly block 9, ensuring the stability of the agitator blade 7. The agitator blades 7 in different positions work together to mix the material in all directions and at multiple angles, effectively avoiding mixing dead zones and improving mixing quality and efficiency.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
