Description

Technical Field

[0001] This utility model relates to the field of candle filter technology, and in particular to an adjustable support bar for a candle filter element. Background Technology

[0002] Candle filters are commonly used solid-liquid separation devices in industrial production, and the installation stability of their filter elements directly affects filtration efficiency and equipment lifespan. During operation, controlling the spacing between filter elements to prevent interference is a crucial step in ensuring the normal operation of the candle filter.

[0003] Currently, although each set of filter elements in existing candle filters is equipped with filter element partitions to separate individual filter elements, there is a lack of effective isolation components between adjacent sets of filter elements. When the filter elements are long and numerous, the bottom of the filter elements are prone to interference due to the lack of support and restraint, which can lead to filter element damage, reduced filtration efficiency, and even equipment failure. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an adjustable support strip for a candle filter element, which can adjust the spacing between adjacent filter elements and prevent interference between them.

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

[0006] An adjustable support bar for a candle filter cartridge includes filter cartridges, each group of filter cartridges being provided with a filter cartridge partition for separating each group of filter cartridges.

[0007] Two fixing screws are fixedly connected to the bottom of the filter element partition;

[0008] An adjustable support bar is detachably and fixedly connected to the fixing screw;

[0009] The adjustable support bar is slidably connected to a fixing nut, which is used to adjust the length of the adjustable support bar.

[0010] Through the above technical solution, two fixing screws are set below the filter element partition to provide a stable installation base for the adjustable support bar and ensure the stability of the support structure. The adjustable support bar and the fixing screws are detachably fixed, which facilitates the installation, replacement and maintenance of the support bar. The sliding connection design between the fixing nut and the adjustable support bar allows the length of the support bar to be flexibly adjusted according to actual needs, thereby adjusting the distance between the two filter elements, adapting to the installation and working requirements of the filter elements under different working conditions, and effectively preventing interference between the filter elements.

[0011] As a further technical solution of this utility model: the adjustable support bar includes a first adjustable support bar and a second adjustable support bar. The end of the first adjustable support bar near the fixed nut is provided with an internal thread; the end of the second adjustable support bar near the fixed nut is provided with an internal thread; the internal thread direction of the first adjustable support bar is opposite to that of the internal thread direction of the second adjustable support bar.

[0012] The above technical solution designs the adjustable support bar as a two-section structure comprising a first adjustable support bar and a second adjustable support bar, with internal threads of opposite directions at the ends of both near the fixing nut, providing a basic structure for adjusting the length of the support bar. By utilizing the differentiated configuration of the thread directions, the rotation of the fixing nut can synchronously drive the two support bars to move in opposite directions or in opposite directions. Compared with the traditional integral support bar, this significantly improves the flexibility and precision of adjustment, realizing bidirectional dynamic adjustment of the filter element spacing. At the same time, the symmetrical support structure formed by the reverse threads can effectively distribute the load and enhance the stability of the support bar after adjustment.

[0013] As a further technical solution of this utility model: the two ends of the fixing nut are respectively provided with internal threads that match the internal threads of the first adjusting support bar and external threads that match the internal threads of the second adjusting support bar.

[0014] Through the above technical solution, external threads matching the internal threads of the first and second adjusting support bars are respectively set at both ends of the fixing nut, thus constructing a complete bidirectional threaded transmission mechanism. This allows the rotational motion of the fixing nut to be precisely converted into the axial displacement of the two support bars. Through the tight meshing of the threaded pairs, backlash-free transmission is achieved, ensuring that the two support bars move synchronously in opposite directions during adjustment. This avoids the eccentricity or jamming problems that may occur in traditional adjustment methods, thereby improving the reliability and stability of the support bar length adjustment and providing structural assurance for the precise control of the filter element spacing.

[0015] As a further technical solution of this utility model: by rotating the fixing nut, the first adjusting support bar and the second adjusting support bar are driven to move in opposite directions or in opposite directions along the axial direction.

[0016] Through the above technical solution, the threaded engagement between the fixed nut and the two support bars allows the rotation of the fixed nut to drive the first and second adjusting support bars to move in opposite or opposite directions along the axial direction, thus achieving length adjustment of the adjustable support bars. The process of converting rotational motion into linear motion is simple and efficient, requiring no complex transmission components. Operators can adjust the filter element spacing by simply rotating the nut, greatly improving the convenience of equipment maintenance. At the same time, the bidirectional synchronous adjustment mechanism ensures the symmetry of the filter element spacing adjustment, avoiding filter element misalignment caused by unilateral adjustment, and effectively enhancing the structural stability of the candle filter during operation.

[0017] As a further technical solution of this utility model: the first adjusting support bar and the second adjusting support bar are both provided with through holes matching the fixing screw at the ends away from the fixing nut, and the fixing screw is fixed by locking nut after passing through the through holes.

[0018] The above technical solution achieves a detachable connection between the support bar and the fixing screw. On the one hand, the precise fit between the through hole and the screw ensures that the support bar stably supports the filter element in the horizontal direction, effectively dispersing the lateral and axial forces on the filter element and preventing filter element displacement or shaking caused by uneven force, thus significantly enhancing the overall stability of the filter structure. On the other hand, the detachable structure allows for the installation and removal of the support bar without complicated tools, enabling operators to quickly replace or maintain the filter element assembly, greatly reducing equipment downtime and maintenance difficulty. It also facilitates adjusting the position of the support bar or replacing damaged parts according to different operating conditions, improving the adaptability and service life of the equipment.

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] 1. This utility model discloses an adjustable support bar for a candle filter element. By setting a fixing screw below the filter element partition, the adjustable support bar is detachably connected to the screw, and the length of the support bar is adjusted by using a sliding fixing nut. This allows for flexible adjustment of the spacing between the candle filter elements, solves the problem of filter element interference, and improves the adaptability and maintenance convenience of the filter.

[0021] 2. This utility model discloses an adjustable support bar for a candle filter element. By designing the adjustable support bar as a two-section structure including a first adjustable support bar and a second adjustable support bar, and setting internal threads with opposite directions of rotation at the ends of the two sections, and configuring matching external threads at both ends of the fixing nut, a bidirectional adjustment function is realized in which the two support bars move synchronously in opposite directions when the fixing nut is rotated. Compared with the traditional single-section adjustment structure, the accuracy and stability of the filter element spacing adjustment are greatly improved.

[0022] 3. This utility model discloses an adjustable support bar for a candle filter element. By opening through holes matching the fixing screw at the ends of the first and second adjustable support bars away from the fixing nut, and fixing them with locking nuts, a detachable connection between the support bar and the fixing screw is achieved. This ensures the stability of the support structure, facilitates the installation and disassembly of the equipment, reduces maintenance costs, and extends the service life of the equipment.

[0030] Example 1:

[0031] Reference Figure 1 and Figure 2This utility model discloses an adjustable support bar for a candle filter element, comprising a filter element 1, each set of filter elements 1 being provided with a filter element partition 2 for separating a single set of filter elements 1. Two fixing screws 3 are vertically fixedly connected below the filter element partition 2. The fixing screws 3 can be made of metal (such as stainless steel), one end of which is vertically fixed to the lower surface of the filter element partition 2 by welding or bolting, and the other end is used to connect the support bar; the perpendicularity error between the axis of the fixing screw 3 and the surface of the filter element partition 2 is controlled within a very small range to ensure the horizontal installation reference of the support bar.

[0032] An adjustable support bar 4 is detachably connected to the fixing screw 3. The adjustable support bar 4 includes a first adjusting support bar 41 and a second adjusting support bar 42. Both the first adjusting support bar 41 and the second adjusting support bar 42 are designed as hollow cylindrical structures, and their inner walls are machined with internal threads in opposite directions. The two ends of the fixing nut 5 are respectively provided with corresponding external threads that match the internal threads of the first adjusting support bar 41 and the second adjusting support bar 42. The external threads are completely matched with the internal threads of the first adjusting support bar 41 and the second adjusting support bar 42 in terms of pitch, tooth profile, nominal diameter, and other parameters. High-precision machining ensures the thread fit accuracy and ensures that the fixing nut 5 can be screwed into the inner ends of both support bars simultaneously.

[0033] The fixed nut 5 and the adjustable support bar 4 are slidably connected by threaded engagement. Since the internal threads of the two support bars rotate in opposite directions and correspond to the external threads of the fixed nut 5, rotating the fixed nut 5 causes the two support bars to move synchronously in opposite directions along the axial direction. For example, if the internal thread of the first adjusting support bar 41 is right-handed and the external thread at one end of the fixed nut 5 is left-handed, then rotating the fixed nut 5 clockwise causes the first adjusting support bar 41 to move axially away from the center of the fixed nut 5, while the second adjusting support bar 42 moves axially in the opposite direction, increasing the distance between the two support bars and lengthening the overall length of the adjustable support bar 4. Conversely, rotating the fixed nut 5 counterclockwise causes the two support bars to move closer to the center, decreasing the distance and shortening the overall length of the adjustable support bar 4. This design, through the opposite threads at both ends of the fixed nut 5, transforms the rotational motion into synchronous, opposite movements of the two support bars, achieving bidirectional adjustment of the support bar length.

[0034] The fixed nut 5 and the adjustable support bar 4 achieve length adjustment and self-locking functions through bidirectional thread engagement. The fixed nut 5 has threads with opposite directions at both ends, which drive the two support bars to move synchronously in opposite directions, achieving bidirectional adjustment of the support bar length. Furthermore, the fixed nut 5 and the adjustable support bar 4 can employ a trapezoidal thread design with a small pitch, utilizing the characteristics of a gentle helix angle and tight thread engagement to form a geometric self-locking effect through friction, effectively resisting the axial load of the filter element 1. Secondly, a nut can be added to the outside of the fixed nut 5, pressing the outer end of the support bar through the end face to offset thread gaps and enhance vibration resistance. Additionally, fine tooth patterns are machined on the contact end face to increase surface contact resistance during tightening, further improving self-locking reliability.

[0035] The fixing nut 5 features a hexagonal head in the center for easy wrench operation, with a rotation torque ≤15 N·m. The outer surface of the support bar can also be equipped with scale lines for visually displaying the adjustment length. The entire adjustment process does not require disassembling the filter element 1; a single person can complete the adjustment of a single set of support bars within 2 minutes, significantly improving equipment maintenance efficiency.

[0036] Reference Figure 1 and Figure 3 Furthermore, both the first adjusting support bar 41 and the second adjusting support bar 42 have through holes at their ends away from the fixing nut 5 that match the fixing screw 3. The diameter of the through holes is adapted to the outer diameter of the fixing screw 3, and a clearance fit is adopted. After the fixing screw 3 passes through the through holes, it is fixed by installing a locking nut 6 at its end. A gasket (such as a rubber gasket) can be added between the locking nut 6 and the first adjusting support bar 41 and the second adjusting support bar 42 to prevent loosening and enhance the sealing performance.

[0037] The working process of the adjustable support bar of the candle filter element of this utility model is as follows:

[0038] Installation stage: The fixing screw 3 is vertically welded to the bottom of the filter element partition 2, so that the first adjusting support bar 41 and the second adjusting support bar 42 are sleeved on the fixing screw 3 through the end through hole, and the initial position of the support bar is fixed with the locking nut 6.

[0039] Adjustment stage: Loosen the fixing nut 5, and drive the first adjusting support bar 41 and the second adjusting support bar 42 to move relative to each other along the axial direction by rotating the fixing nut 5, so as to extend or shorten the length of the adjustable support bar 4.

[0040] Locking stage: After adjusting the adjustable support bar 4 to the required length, tighten the fixing nut 5 to lock the length of the support bar through the self-locking characteristic of the thread engagement, thereby adjusting the spacing between the bottoms of adjacent filter elements 1 and preventing interference between filter elements 1.

[0041] The implementation principle of this utility model is as follows: This utility model utilizes the synergistic effect of threaded transmission and mechanical support. Through the cooperation of adjustable support bar 4 and fixed nut 5, it achieves precise adjustment and stable support of the spacing of the candle filter element 1. Specifically, when the fixed nut 5 is rotated, the external threads at both ends of the nut 5 and the internal threads at the inner ends of the first adjustable support bar 41 and the second adjustable support bar 42 form a helical pair. Based on the axial displacement characteristics of the threaded transmission, the rotational motion is converted into synchronous linear motion of the two support bars, thereby achieving adjustment of the total length of the support bars. At the same time, the fixed screw 3, which is perpendicular to the filter element partition 2, provides horizontal support force for the support bars. The support bars cooperate with the fixed screw 3 through the through holes at both ends of the support bars and are locked by the locking nut 6 to form a stable support structure. This effectively resists the lateral force at the bottom of the filter element 1, ensuring the spacing stability of the filter element 1 under vibration or fluid impact conditions and preventing interference of the filter element 1.

[0042] The embodiments described herein 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.
