Description

Technical Field

[0001] This utility model relates to the field of candle filter technology, and in particular to a novel stirring spindle fixing support mechanism. Background Technology

[0002] During the operation of a fully automatic candle filter, the main shaft, as the core transmission component, directly affects the working efficiency and service life of the equipment. Therefore, it is of great practical necessity to set up a reliable support mechanism for the main shaft.

[0003] In existing technologies, the power transmission structure of fully automatic candle filters typically involves a motor rotating to drive a transmission shaft, which is connected to a main shaft via a coupling. The lower end of the main shaft is connected to a stirring element, but no supporting or fixing components are installed in the main shaft area between the stirring element and the coupling. With this structural design, due to the long length of the main shaft and the lack of effective support and constraint, it is prone to severe shaking during high-speed rotation. This shaking not only causes collisions and friction between the main shaft and the filter element inside the cylinder, affecting the normal operation and lifespan of the filter element, but also reduces the equipment's efficiency. In severe cases, it can directly damage the filter element, thus affecting the smooth progress of subsequent processes, and may even damage the reducer shaft hole, causing unnecessary economic losses to the user. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of stirring spindle fixing support mechanism, which solves the problem of no support and fixation for the spindle of the fully automatic filter, reduces the shaking of the spindle, and avoids it from affecting the internal filter elements.

[0005] The above-mentioned utility model objective is achieved through the following technical solution:

[0006] A novel stirring spindle fixing support mechanism includes a cylindrical body and a spindle rotatably disposed within the cylindrical body.

[0007] Multiple support blocks are fixedly connected to the upper part of the cylinder; an upper support ring is detachably fixed to the support blocks by fasteners; a fixing member is provided in the center hole of the upper support ring, and the upper part of the main shaft is rotatably inserted through the fixing member;

[0008] A lower support ring is fixedly connected to the lower part of the cylinder. The lower end of the main shaft extends into the central hole of the lower support ring, and a shaft retaining spring is provided at the lower end of the main shaft. The shaft retaining spring cooperates with the lower end face of the lower support ring to achieve axial positioning.

[0009] The above technical solution achieves dual constraints at both ends of the spindle. The upper end effectively suppresses the radial wobble of the spindle through the support ring and the fixing component, while the lower end achieves radial support and axial limit through the cooperation of the support ring and the shaft retaining spring. This significantly improves the overall rotational stability of the spindle, avoids collisions with internal components, and extends the service life of the equipment.

[0010] As a further technical solution of this utility model: the number of the support blocks is three, and they are evenly distributed along the inner wall circumferentially of the cylinder.

[0011] By employing the above technical solution and evenly distributing three support blocks circumferentially, the most stable and balanced support force can be provided for the upper support ring, forming a stable three-point support structure. This effectively prevents the support ring from tilting due to uneven force, thereby further enhancing the stability and smoothness of the spindle rotation.

[0012] As a further technical solution of this utility model: a connecting hole is provided on the circumference of the upper support ring, and a fixing hole corresponding to the connecting hole is provided on the support block, and the fastener passes through the connecting hole and the fixing hole to achieve connection.

[0013] The above technical solution utilizes the corresponding connecting holes and fixing holes for installation, ensuring accurate positioning and convenient assembly and disassembly of the upper support ring, which greatly facilitates the assembly, debugging, and subsequent maintenance of the equipment.

[0014] As a further technical solution of this utility model: the fastener includes a connecting bolt and a connecting nut.

[0015] The above technical solution uses standard components such as bolts and nuts for connection, resulting in a simple and reliable structure, convenient assembly and disassembly, and the ability to maintain a stable connection under long-term vibration of the equipment, thus ensuring the long-term reliability of the support structure.

[0016] In summary, this utility model has at least one of the following beneficial technical effects:

[0017] 1. This utility model discloses a novel fixed support mechanism for a stirring spindle. Through the dual constraint structure of "support block + upper support ring + fixing component" at the upper end of the spindle and "lower support ring + shaft retaining spring" at the lower end, it achieves the synergistic effect of suppressing radial wobble and limiting axial movement of the spindle, significantly improving the rotational stability of the spindle, avoiding collisions with internal components, and extending the service life of the equipment.

[0018] 2. This utility model discloses a novel fixed support mechanism for a stirring main shaft, which achieves balanced support of the upper support ring by setting three support blocks evenly distributed along the circumference of the inner wall of the cylinder, preventing the support ring from tilting and further enhancing the stability of the main shaft rotation.

[0019] 3. This utility model discloses a novel fixed support mechanism for a stirring spindle, which achieves precise positioning, convenient assembly and disassembly, and long-term stable connection of the upper support structure through the corresponding hole matching of the upper support ring and the support block and the connection of bolts and nuts, thus ensuring the ease of assembly and maintenance and the reliability of operation of the support mechanism.

[0031] Example 1:

[0032] Reference Figure 1 This utility model discloses a novel stirring spindle fixing support mechanism, including a cylinder 1 and a spindle 2 rotatably disposed inside the cylinder 1. Multiple support blocks 9 are welded to the upper part of the cylinder 1, and the number of support blocks 9 is three and they are evenly distributed along the inner wall of the cylinder 1. The included angle between adjacent support blocks 9 is 120°. After welding, it is necessary to ensure that the upper end surfaces of the support blocks 9 are on the same horizontal plane. The support blocks 9 are detachably and fixedly connected to the upper support ring 4 by fasteners.

[0033] Reference Figure 2 A connecting hole 41 is provided on the circumference of the upper support ring 4, as shown in the figure. Figure 3 The upper support ring 4 has a flat ring structure with a thin axial thickness, which can fit the installation space on the upper part of the cylinder 1 and stably support the components in the central hole, ensuring the support stability of the upper part of the main shaft 2.

[0034] Reference Figure 6 The support block 9 has a fixing hole 91 corresponding to the connecting hole 41. The fixing hole 91 is an internal threaded hole for fasteners. The fasteners are conventional hexagonal connecting bolts 10 and matching connecting nuts 8. By passing through the connecting hole 41 and the fixing hole 91, the support block 9 can be fixed to the upper support ring 4.

[0035] A fixing element 11 is provided in the center hole of the upper support ring 4, and the upper part of the spindle 2 is rotatably inserted in the fixing element 11. The fixing element 11 can be selected according to the working conditions: copper alloy or nylon sliding bushing is selected for low speed and light load, and smooth rotation is achieved through a small clearance fit; deep groove ball bearing is selected for high speed and heavy load, and wear is reduced by rolling friction. Both structures can be installed stably and do not affect the rotation of the spindle.

[0036] The upper end of the main shaft 2 is connected to the drive shaft 5 via a suitable coupling 7. The coupling 7 is connected to both of them by a pin and a cotter pin is added to prevent them from coming off. The end of the drive shaft 5 away from the coupling 7 is fixed to the output hole of the drive element 6 by a flat key to ensure stable power transmission.

[0037] Reference Figure 1 A lower support ring 13 is welded to the lower part of the cylinder 1, as shown in the reference. Figure 5 The lower support ring 13 is also a flat ring structure with a compact axial dimension, which not only fits the spatial layout of the lower part of the cylinder 1, but also facilitates its integration with subsequent components; see reference. Figure 4 The lower end of the spindle 2 extends into the center hole of the lower support ring 13, and an annular groove is provided at the lower end of the spindle 2. A shaft retainer 14 is installed in the annular groove. The shaft retainer 14 cooperates with the lower end face of the lower support ring 13 to achieve axial positioning and prevent axial movement of the spindle 2 during operation.

[0038] Reference Figure 1 and Figure 7 The lower end of the main shaft 2 is also connected to a stirring device 12. The stirring device 12 is fixed to the main shaft 2 by welding or key connection. A filter element 3 is also provided inside the cylinder 1. The filter element 3 is located between the main shaft 2 and the inner wall of the cylinder 1, and is located in the area between the support block 9 and the lower support ring 13, so as to avoid interference with the rotating main shaft 2 and the stirring device 12.

[0039] The assembly and workflow of this utility model are as follows: First, the support block 9 and the lower support ring 13 are welded to the upper and lower parts of the inner wall of the cylinder 1 respectively to ensure stable position and coaxiality. Next, the stirring device 12 and the main shaft 2 are fixed by welding or key connection. The shaft retainer 14 is clamped in the annular groove at the lower end of the main shaft 2. Then, the lower end of the main shaft 2 with the annular groove is inserted into the center hole of the lower support ring 13. At this time, the main shaft 2 is radially supported by the lower support ring 13, and the shaft retainer 14 and the lower end face of the lower support ring 13 abut against each other to complete the axial limitation.

[0040] Subsequently, a filter element 3 is installed inside the cylinder 1. This element is located between the main shaft 2 and the inner wall of the cylinder 1, and between the support block 9 and the lower support ring 13. After the filter element 3 is installed, the hole on the circumference of the upper support ring 4, whose center hole has a pre-installed fixing part 11, is aligned with the fixing hole 91 on the support block 9. The connecting bolt 10 is passed through the corresponding hole and then tightened with the connecting nut 8 to achieve a stable connection between the upper support ring 4 and the support block 9. Finally, the upper end of the main shaft 2 is connected to the drive shaft 5 using a coupling 7. The connection between the coupling 7 and the main shaft 2 and the drive shaft 5 is fixed with pins. Then, the end of the drive shaft 5 away from the coupling 7 is fixed to the output hole of the drive element 6 with a key to complete the overall assembly.

[0041] During operation, the drive element 6 outputs power, which is transmitted to the main shaft 2 via the transmission shaft 5 and coupling 7. The main shaft 2 rotates stably under the combined action of the radial constraint of the fixing part 11, the radial support of the lower support ring 13, and the axial limit of the shaft snap ring 14, driving the stirring device 12 to operate synchronously and preventing the main shaft 2 from shaking and colliding with the filter element 3.

[0042] The implementation principle of this utility model is as follows: Stable operation of the main shaft 2 is achieved through the coordinated constraint of the upper and lower support structures. The upper support system provides a stable base for the upper support ring 4 through three evenly distributed support blocks 9, ensuring that the fixing component 11 and the upper part of the main shaft 2 always maintain precise alignment, forming effective radial alignment. The lower support system provides radial support to the lower end of the main shaft 2 through the central hole of the lower support ring 13. The central hole and the main shaft 2 are in clearance fit, ensuring smooth rotation while limiting radial offset. Simultaneously, the mechanical limiting fit between the shaft retaining spring 14 and the lower end face of the lower support ring 13 reliably prevents the main shaft 2 from moving upwards. The upper and lower support systems together constitute a complete constraint system. The upper end primarily provides radial constraint, while the lower end combines radial support and axial limiting functions. This coordinated action ensures that the main shaft 2 maintains a stable running trajectory during rotation, effectively avoiding interference with the surrounding filter elements 3, thereby guaranteeing long-term stable operation of the equipment.

[0043] The specific embodiments described are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
