Description

Technical Field

[0001] The utility model relates to the technical field of filter bags, and more particularly to a high-strength telescopic filter bag. Background Art

[0002] In existing technologies, filter bags are a type of equipment used to filter solid particles and liquids. They are widely used in industries such as industry, environmental protection, food processing, and pharmaceuticals. Filter bags are usually made of high-strength, corrosion-resistant, and high-temperature-resistant materials. They can effectively capture and separate impurities in the air or liquid, ensuring a clean production environment and product quality.

[0003] A significant problem with existing filter bag designs is the lack of positioning and retractable functions, which means that users cannot precisely adjust the length of the filter bag according to specific filtration requirements. Since the filter bag has a fixed length, it cannot adapt to space constraints or filtration efficiency requirements under different working conditions. This design limitation may result in the filter bag not achieving the best filtration effect in actual applications, and also restricts its use in certain special environments. For example, in places where space is limited or when filtering media with different viscosities, the inability to adjust the length of the filter bag may result in low filtration efficiency or incomplete filtration.

[0004] In addition, the filter bags in the prior art also have inconveniences in positioning and fixing. Due to the lack of an effective positioning and fixing mechanism, the filter bags may shift or shake during installation and use, which not only affects the filtration effect, but may also cause damage to the filter bags. This instability may also increase maintenance costs, because frequent adjustments and repairs consume more time and resources. In the absence of a positioning and fixing mechanism, the installation process of the filter bags becomes more complicated, and additional accessories and steps are required to ensure that the filter bags can be firmly installed on the filtration system. This design deficiency seriously limits the applicability and convenience of the filter bags, leaving users lacking flexible solutions when facing different filtration challenges. Utility Model Content

[0005] (1) Technical problems solved

[0006] In response to the problems existing in the prior art, the utility model provides a high-strength telescopic filter bag to solve the technical problems mentioned in the background art, such as the lack of positioning and telescopic operation functions and the lack of an effective positioning and fixing mechanism.

[0007] (2) Technical solution

[0008] The filter bag of claim 1, wherein the filter bag comprises a plurality of filter elements, the plurality of filter elements comprising a plurality of filter elements, the plurality of filter elements comprising a plurality of filter elements, and the plurality of filter elements comprising a plurality of filter elements.

[0009] The utility model is further configured such that the mounting ring is configured as a flange. The design of the flange provides a stable mounting base, enhances the connection strength between the filter bag body and the external filtration system, and ensures the stability of the filter bag during operation. At the same time, the design of the flange also facilitates the installation and disassembly of the filter bag, thereby improving the convenience of maintenance.

[0010] The utility model is further configured such that multiple groups of the clamping blocks are slidably mounted on the clamping sleeves, and push springs are connected between the multiple groups of the clamping blocks and the inner sides of the clamping sleeves. The push springs provide additional thrust, so that the clamping blocks can be more firmly clamped into the clamping grooves, thereby enhancing the positioning stability. This design allows the filter bag body to maintain a predetermined length during the extension and retraction process, thereby improving the filtration efficiency.

[0011] The utility model is further configured such that the inner wall of the locking sleeve is provided with a locking groove, and the locking grooves are provided in multiple groups. The design of the locking grooves increases the reliability of the locking, ensures the stability of the filter bag body during extension and positioning, and avoids the decrease in filtration efficiency due to the displacement of the snap-in block.

[0012] The utility model is further configured such that a limit rod is provided on the snap-fit ​​sleeve, and the limit rod is provided in multiple groups and is slidably connected to the locking sleeve. The design of the limit rod ensures the stability of the locking sleeve in the correct position, prevents inaccurate adjustment of the length of the filter bag body due to excessive movement of the locking sleeve, and improves the accuracy of the operation.

[0013] The utility model is further configured such that a tension spring is provided between the coupling sleeve and the lock sleeve, and multiple groups of the tension springs are provided. The design of the tension spring makes the unlocking process smoother, reduces the operating force, improves the convenience of operation, and also ensures the stability and reliability of the lock sleeve after unlocking.

[0014] The utility model is further configured such that the bottom surfaces of multiple groups of the snap-fit ​​sleeves are fixedly connected to the top surface of the connecting ring. This fixed connection design enhances the stability of the filter bag body during the expansion and contraction process, reduces the risk of damage to the filter bag body due to displacement of the connecting part, and increases the service life of the filter bag.

[0015] The utility model is further configured such that an unlocking mechanism is provided on the outer wall of the clamping sleeve, and the unlocking mechanism includes a control sleeve, an inclined block sleeve and an inclined push block. The control sleeve is rotatably mounted on the bottom end of the clamping sleeve, the inclined block sleeve is mounted on the top surface of the control sleeve, and a plurality of groups of inclined push blocks are provided, all of which are mounted on the bottom surface of the locking sleeve. The design of the unlocking mechanism makes it simple and quick to adjust the length of the filter bag body, reduces the operation time, and improves the work efficiency. At the same time, the filter bag body after unlocking can be freely extended and retracted to adapt to different filtering requirements, thereby increasing the applicability of the filter bag.

[0016] (3) Beneficial effects

[0017] Compared with the existing technology, the utility model provides a high-strength telescopic filter bag with the following beneficial effects:

[0018] 1. The design of the telescopic mechanism realizes the flexible telescopic function of the filter bag body through the coordinated action of the mounting ring, bottom ring, slide rod, connecting ring and tension spring. This design enables the filter bag to adjust its length according to actual needs and adapt to different filtering environments and space limitations. The mounting ring is set as a flange to provide a stable installation foundation, while the bottom ring ensures the stability of the bottom of the filter bag. The sliding connection between the slide rod and the connecting ring allows the filter bag body to smoothly extend and retract. The tension spring provides rebound force during the elongation process, ensuring that the filter bag can return to its original length after the external force is removed. This flexibility greatly improves the application range and use efficiency of the filter bag.

[0019] 2. The positioning mechanism provides precise length positioning and fixing functions for the filter bag body through the ingenious cooperation of the snap groove, snap sleeve, snap block, locking block and locking sleeve. The snap block can be accurately snapped into the snap groove on the slide rod under the action of the push spring, and the design of the locking block and locking sleeve further enhances the stability of the fixation. The cooperation between the lock groove on the inner wall of the locking sleeve and the locking block provides additional locking force to ensure that the filter bag maintains a stable length during use. The setting of the limit rod prevents excessive movement of the locking sleeve and increases the reliability of the entire mechanism. This multiple locking design not only improves the safety of the filter bag, but also ensures the stability of the filtration efficiency.

[0020] 3. The design of the unlocking mechanism, including the control sleeve, the inclined block sleeve and the inclined push block, provides a convenient solution for the rapid adjustment of the filter bag length. By simply rotating the control sleeve, the inclined block sleeve can be driven to rotate, and then the upward thrust is generated through the contact between the inclined surface and the inclined push block, so that the locking sleeve moves upward and the lock of the clamping block is released. This design greatly simplifies the operation process of adjusting the filter bag length and improves the efficiency and accuracy of the adjustment. After unlocking, the filter bag can be freely extended to the new length and then locked again. This flexibility enables the filter bag to quickly adapt to different filtration needs.

The sliding rod 4 is provided with multiple groups and both ends are respectively connected to the mounting ring 2 and the bottom ring 3. The connecting ring 5 is provided with multiple groups installed on the outer wall of the filter bag body 1 and are all slidably connected with the multiple groups of sliding rods 4. The tension spring 6 is provided with multiple groups and is respectively installed between the multiple groups of connecting rings 5. The multiple groups of sliding rods 4 are provided with a positioning mechanism. The positioning mechanism comprises a clamping groove 7, a clamping sleeve 8, a clamping block 9, a locking block 10 and a locking sleeve 11. The clamping groove 7 is arranged on the slide rod 4, the clamping sleeve 8 is arranged on the outer wall of the slide rod 4, the clamping block 9 is provided with multiple groups installed on the clamping sleeve 8, the locking block 10 is arranged at the outer end of the multiple groups of clamping blocks 9, and the locking sleeve 11 is arranged on the outside of the clamping sleeve 8.

[0031] The mounting ring 2 is configured as a flange. The mounting ring 2 serves as the top fixing portion of the filter bag body 1 and is designed as a flange. The mounting ring 2 is fixed to the external filter system by bolts or other connection methods.

[0032] Multiple groups of clamping blocks 9 are slidably installed on the clamping sleeve 8, and push springs 12 are connected between the multiple groups of clamping blocks 9 and the inner side of the clamping sleeve 8. The clamping blocks 9 are slidably installed on the clamping sleeve 8. Through the action of the push spring 12, the clamping blocks 9 can be clamped into the clamping groove 7 on the slide rod 4 to realize the length positioning of the filter bag body 1.

[0033] The inner wall of the locking sleeve 11 is provided with locking grooves 13, and there are multiple groups of locking grooves 13. The inner wall of the locking sleeve 11 is provided with multiple groups of locking grooves 13. These locking grooves cooperate with the locking block 10 to lock the clamping block 9 to prevent it from shifting during the expansion and contraction process of the filter bag body 1.

[0034] A limit rod 14 is provided on the clamping sleeve 8. There are multiple groups of limit rods 14 and they are slidably connected to the locking sleeve 11. The limit rod 14 is provided on the clamping sleeve 8 and is slidably connected to the locking sleeve 11 to limit the movement range of the locking sleeve 11 and prevent it from excessive movement.

[0035] A tension spring 15 is connected between the clamping sleeve 8 and the locking sleeve 11. There are multiple groups of tension springs 15. The tension springs 15 are arranged between the clamping sleeve 8 and the locking sleeve 11 to provide rebound force during the unlocking process, helping the locking sleeve 11 to move up and release the lock on the clamping block 9.

[0036] The bottom surfaces of multiple groups of clamping sleeves 8 are fixedly connected to the top surface of the connecting ring 5. The bottom surfaces of the clamping sleeves 8 and the top surface of the connecting ring 5 are fixedly connected, which ensures the stability between the connecting ring 5 and the clamping sleeves 8 and provides support for the expansion and contraction of the filter bag body 1.

[0037] In this embodiment, the filter bag body 1 is fixed to the external filter system through the mounting ring 2. When the filter bag body 1 needs to be extended, an external force acts on the connecting ring 5, causing the connecting ring 5 to slide along the slide rod 4 and drive the top end of the filter bag body 1 to stretch and retract. The tension spring 6 is stretched to provide a rebound force. When the external force is removed, the rebound force of the tension spring 6 will restore the filter bag body 1 to its original length. When the filter bag body 1 is extended to the required length, the clamping block 9 is clamped into the clamping groove 7 on the slide rod 4 under the action of the push spring 12. The locking block 10 is located at the outer end of the clamping block 9 and is abutted by the locking groove 13 set on the inner side of the locking sleeve 11 to further ensure the stability of the clamping.

[0038] See also Figure 5 As an implementation method of the unlocking mechanism: an unlocking mechanism is provided on the outer wall of the clamping sleeve 8, and the unlocking mechanism includes a control sleeve 16, an inclined block sleeve 17 and an inclined push block 18. The control sleeve 16 is rotatably installed at the bottom end of the clamping sleeve 8, and the inclined block sleeve 17 is installed on the top surface of the control sleeve 16. There are multiple groups of inclined push blocks 18, all of which are installed on the bottom surface of the lock sleeve 11. When the control sleeve 16 rotates, the inclined block sleeve 17 rotates accordingly, and the inclined surface contacts the inclined push block 18 to generate thrust, causing the lock sleeve 11 to move upward, thereby releasing the lock on the clamping block 9.

[0039] More specifically, when the length of the filter bag needs to be adjusted, the control sleeve 16 is rotated to drive the inclined block sleeve 17 to rotate. The inclined surface on the inclined block sleeve 17 contacts the inclined push block 18 on the bottom surface of the locking sleeve 11, generating an upward thrust. This thrust causes the locking sleeve 11 to move upward, thereby releasing the lock on the clamping block 9. Once the lock is released, the filter bag can be freely extended and adjusted to a new length. After the lock is released, the filter bag length can be adjusted again.

[0040] In summary, when the overall equipment is in use or running: the filter bag body 1 is fixed to the external filtration system through the mounting ring 2; when the filter bag body 1 needs to be extended, external force acts on the connecting ring 5, causing the connecting ring 5 to slide along the slide rod 4, and driving the top end of the filter bag body 1 to stretch and retract, and the tension spring 6 is stretched to provide a rebound force. When the external force is removed, the rebound force of the tension spring 6 will restore the filter bag body 1 to its original length. When the filter bag body 1 is extended to the required length, the clamping block 9 is clamped into the clamping groove 7 on the slide rod 4 under the action of the push spring 12; the locking block 10 is located at the outer end of the clamping block 9, and is abutted by the locking groove 13 set on the inner side of the locking sleeve 11, further ensuring the stability of the clamping.

[0041] When the length of the filter bag needs to be adjusted, the control sleeve 16 is rotated to drive the inclined block sleeve 17 to rotate. The inclined surface of the inclined block sleeve 17 contacts the inclined push block 18 on the bottom surface of the locking sleeve 11, generating an upward thrust. This thrust causes the locking sleeve 11 to move upward, thereby releasing the lock on the clamping block 9. Once the lock is released, the filter bag can be freely extended and adjusted to a new length. After the lock is released, the filter bag length can be adjusted again.

[0042] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded.
