Description

Technical Field

[0001] This utility model relates to the field of agitator blade technology, and in particular to a quick-installation glass-lined agitator blade assembly. Background Technology

[0002] Quick-install glass-lined agitators have wide and important applications in many industries such as chemical, pharmaceutical, and food processing. The performance of its core component, the impeller assembly, directly affects the mixing effect, reaction efficiency, and the stability of the entire production process and product quality. Glass enamel material has excellent corrosion resistance, can withstand the erosion of various chemicals, and has a smooth surface that is not prone to material buildup, making it easy to clean and maintain. This makes quick-install glass-lined agitators an ideal choice for handling corrosive media mixing tasks.

[0003] In existing quick-installation glass-lined agitator impeller assemblies, the impeller and agitator shaft or other connecting parts are usually bolted together. No dedicated sealing structure is designed for the bolt gaps. When the agitator is rotating at high speed or the reaction system is under pressure, the reaction medium can easily leak through the gaps between the bolts and the connecting holes. This not only causes material loss but may also lead to equipment corrosion, environmental pollution, and even endanger operator safety. Leakage also results in the bolts and connecting parts being constantly immersed in corrosive media, accelerating bolt corrosion and damaging the glass-lined coating, thus shortening the impeller assembly's service life. Therefore, we propose a quick-installation glass-lined agitator impeller assembly. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a quick-installation glass-lined agitator blade assembly. This addresses the issue that in existing quick-installation glass-lined agitator blade assemblies, the blades and agitator shaft or other connecting parts are usually connected by bolts, without a dedicated sealing structure designed for the bolt connection gap. When the agitator is rotating at high speed or the reaction system is under pressure, the reaction medium is prone to leakage through the gap between the bolts and the connecting holes. This not only causes material loss, but may also lead to equipment corrosion, environmental pollution, and even endanger the safety of operators. The leakage problem also causes the bolts and connecting parts to be immersed in corrosive media for a long time, accelerating bolt corrosion and damage to the glass-lined coating, and shortening the service life of the blade assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation glass-lined stirrer blade assembly, comprising: The stirring shaft has a positioning groove at its bottom; Install a sealing structure, which is located on the stirring shaft; The sealing structure includes a mounting ring, a mounting cylinder, and a sealing top cover.

The sealing top cover is slidably fitted onto the outside of the mounting ring. Multiple screw rods are fixedly connected to the inner top wall of the sealing top cover. The bottom ends of the multiple screw rods pass through the corresponding through holes and through holes. The bottom ends of the multiple screw rods are located inside the threaded groove and are locked with nuts.

[0006] Preferably, the mounting sealing structure further includes a sealing base plate and a threaded ring, the threaded ring being threadedly connected inside the threaded groove, and the sealing base plate being fixedly connected to the bottom of the threaded ring.

[0007] Preferably, the bottom of the mounting cylinder is provided with an annular groove, and a sealing ring is interference-fitted inside the annular groove. The sealing ring is fixedly connected to the top of the sealing base plate.

[0008] Preferably, a positioning plate is fixedly connected inside the mounting cylinder, and the positioning plate is slidably connected to the inside of the positioning groove.

[0009] Preferably, the inner top wall of the sealing top cover fits against the top of the mounting ring, and the inner wall of the sealing top cover fits against the outer surface of the mounting ring.

[0010] Preferably, all of the multiple through holes 2 are internally connected to the corresponding through hole 1.

[0011] Preferably, the three blades are arranged in a circular array outside the mounting cylinder.

[0012] Preferably, the plurality of screw rods are arranged in a circular array on the sealing top cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This quick-install glass-lined agitator impeller assembly, through the inner top wall of the sealing top cover fitting against the top of the mounting ring and the inner wall fitting against the outer surface of the mounting ring, can directly seal the assembly gap between the mounting ring and the top of the mounting cylinder, preventing media leakage from the top; under the threaded seal of the sealing bottom plate through the threaded ring and the threaded groove inside the thread, it can block media leakage from the bottom bolt connection area, avoid material loss caused by leakage of reaction media, prevent equipment corrosion and environmental pollution caused by leakage of corrosive media, and thus improve the service life of the impeller assembly.

[0020] Stirring shaft 1: As the rotating shaft of the stirring device, it has a positioning groove 8 at the bottom and a mounting ring 6 fixedly attached to the outer surface for installing and driving the installation sealing structure and blade 2 to rotate; Blade 2: There are three blades in total, which are fixedly connected to the outer surface of the mounting cylinder 3 in a circular array and rotate synchronously with the mounting cylinder 3 to achieve the stirring effect on the material; Installation cylinder 3: It is slidably sleeved on the outer surface of the stirring shaft 1, with a positioning plate 9 fixedly connected inside and three blades 2 fixedly connected on the outer surface. Multiple through holes 10 are opened at the top, and threaded grooves 12 and annular grooves 13 are opened at the bottom for installing blades 2 and connecting the sealing top cover 4 and sealing bottom plate 5. Sealing top cover 4: It is slidably sleeved on the outside of the mounting ring 6. The inner top wall is in contact with the top of the mounting ring 6 and the outer surface of the mounting ring 6. The inner top wall is fixedly connected to multiple screw rods 11 arranged in a circular array, which are used to seal the top of the mounting structure and connect the mounting ring 6 and the mounting cylinder 3. Sealing base plate 5: It is fixedly connected to the bottom of the threaded ring 14 and the top is fixedly connected to the sealing ring 15. It is connected to the mounting cylinder 3 through the threaded ring 14 and is used to seal the bottom of the mounting structure. Mounting ring 6: It is fixedly sleeved on the outer surface of the stirring shaft 1, and has multiple through holes 7 on the top, which fit into the sealing top cover 4 to assist in the installation of the sealing top cover 4 and enhance the sealing effect. Through hole 1 7: Multiple through holes are opened on the top of the mounting ring 6 and communicate with the interior of the corresponding through hole 2 10, allowing the screw rod 11 to pass through; Positioning groove 8: It is formed at the bottom of the stirring shaft 1 and is slidably connected to the positioning plate 9. It is used to position the relative position of the mounting cylinder 3 and the stirring shaft 1 to prevent the mounting cylinder 3 from rotating circumferentially. Positioning plate 9: It is fixedly connected inside the mounting cylinder 3 and slidably connected with the positioning groove 8, so as to achieve circumferential positioning of the mounting cylinder 3 in conjunction with the positioning groove 8; Through hole 2 10: Multiple through holes are opened on the top of the mounting cylinder 3 and communicate with the interior of the corresponding through hole 1 7, allowing the screw rod 11 to pass through and extend to the threaded groove 12; Screw rods 11: Multiple screw rods are fixedly connected to the inner top wall of the sealing top cover 4 in a circular array. The bottom end passes through the through hole 1 7 and the through hole 2 10 and extends into the threaded groove 12. They are locked by nuts and used to fix the sealing top cover 4, the mounting ring 6 and the mounting cylinder 3. Threaded groove 12: It is formed at the bottom of the mounting cylinder 3 to accommodate the bottom end of the screw rod 11 and to be threadedly connected to the threaded ring 14; Threaded ring 14: Threaded connection inside threaded groove 12, with bottom fixed connection to sealing base plate 5, used to fix sealing base plate 5 to the bottom of mounting cylinder 3; Sealing ring 15: It is fixedly connected to the top of the sealing base plate 5 and is interference-fitted inside the annular groove 13. When compressed, it undergoes elastic deformation to fill the gap between the sealing base plate 5 and the bottom of the mounting cylinder 3, thereby enhancing the sealing effect.

[0021] Example 1: like Figure 1-5 As shown, in chemical production, it is necessary to frequently change the impeller blades to adapt to different reactants and stirring requirements.

[0022] The sealing structure is installed using the basic structure described above. The sealing top cover 4 is slidably sleeved onto the outside of the mounting ring 6, so that the inner top wall of the sealing top cover 4 fits against the top of the mounting ring 6 and the inner wall fits against the outer surface of the mounting ring 6, ensuring that the two are in close contact.

[0023] The threaded ring 14, which is fixedly connected to the sealing base plate 5, is threaded into the threaded groove 12 of the mounting cylinder 3. As the threaded ring 14 is tightened, the sealing base plate 5 can fit against the bottom of the mounting cylinder 3. Thus, the fitting structure of the sealing top cover 4 and the mounting ring 6, and the locking fit of the screw rod 11 and the nut together form a multi-seal system, blocking the channel for material or medium to leak from the assembly gap during the stirring process.

[0024] Example 2: like Figure 4-5 As shown, the sealing ring 15 is fixedly connected to the sealing base plate 5, and the sealing ring 15 is tightly fitted to the inside of the annular groove 13. Due to the interference fit and compression, the sealing ring 15 undergoes elastic deformation, filling the gap between the sealing base plate 5 and the bottom of the mounting cylinder 3.

[0025] Furthermore, when using this device, the mounting cylinder 3 is first slidably fitted onto the outer surface of the stirring shaft 1, ensuring that the positioning plate 9 fixedly connected inside the mounting cylinder 3 is slidably connected to the positioning groove 8 opened at the bottom of the stirring shaft 1, quickly positioning the relative position of the mounting cylinder 3 and the stirring shaft 1, preventing the mounting cylinder 3 from rotating around the stirring shaft 1, laying the foundation for subsequent fixing; at this time, the three blades 2 arranged in a circular array on the outer surface of the mounting cylinder 3 are synchronously positioned with the mounting cylinder 3, completing the initial assembly of the blades.

[0026] Next, the sealing top cover 4 is slidably fitted onto the outside of the mounting ring 6, so that the inner top wall of the sealing top cover 4 fits against the top of the mounting ring 6 and the inner wall fits against the outer surface of the mounting ring 6, ensuring tight contact between the two; then the position of the sealing top cover 4 is adjusted so that the bottom ends of the multiple screw rods 11 arranged in a circular array on the inner top wall of the sealing top cover 4 are aligned with the multiple through holes 7 on the top of the mounting ring 6, and extend through the through holes 7 to the multiple through holes 10 on the top of the mounting cylinder 3. The through holes 10 are connected to the through holes 7, and finally the bottom ends of the screw rods 11 are inserted into the threaded grooves 12 at the bottom of the mounting cylinder 3; the screw rods 11 are locked in the threaded grooves 12 by nuts, realizing the fixed connection between the sealing top cover 4, the mounting ring 6 and the mounting cylinder 3, and completing the main assembly of the blade assembly.

[0027] The threaded ring 14, which is fixedly connected to the sealing base plate 5, is threaded into the threaded groove 12 of the mounting cylinder 3. As the threaded ring 14 is tightened, the sealing ring 15 is tightly fitted together. Due to the interference fit and compression, the sealing ring 15 undergoes elastic deformation, filling the gap between the sealing base plate 5 and the bottom of the mounting cylinder 3. At the same time, the fitting structure between the sealing top cover 4 and the mounting ring 6, and the locking fit between the screw rod 11 and the nut, together form a multi-layer sealing system of "top-middle-bottom", blocking the channel for material or medium to leak from the assembly gap during the stirring process.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
