Description

Technical Field

[0001] This utility model relates to the field of rust inhibitor production technology, specifically a bag filter used in rust inhibitor production. Background Technology

[0002] In rust inhibitor production, bag filters are key precision filtration equipment used to remove mechanical impurities, colloidal particles, and catalyst residues from raw materials, ensuring product purity and stability. They are characterized by simple structure, adjustable filtration precision, and wide adaptability to various working conditions, and are widely used in chemical, food, water treatment, and pharmaceutical industries. The core structure of a bag filter includes a shell, filter bags, support baskets, and sealing components. Its core working principle is that the fluid to be filtered enters the filter shell through the inlet and flows to the outside of the filter bag. As the fluid passes through the filter bag, impurities are trapped by the filter bag fibers and adhere to the inside or surface of the filter bag. The filtered clear liquid passes through the inside of the filter bag and collects at the outlet at the bottom or side of the shell, completing solid-liquid separation.

[0003] In the current technology, the housing of bag filters is mostly made of stainless steel. Depending on the flow rate, the housing can be divided into single-chamber and multi-chamber. The basket is built into the housing to support the filter bag. The sealing ring at the opening of the filter bag is pressed by the flange ring so that the opening of the filter bag covers the top of the basket. The flange ring is fixed with several bolts, and the flange ring is also equipped with a sealing ring for sealing. In practical use, filter bags need to be replaced regularly to ensure the filtration effect on the fluid. When replacing them, it is necessary to ensure that the flange ring, sealing ring, and filter bag sealing ring are aligned and the bolts are tightened in a diagonal order with uniform force. If the bolts are not tightened in a diagonal order or the bolt tightness is inconsistent, the flange ring will be subjected to uneven force and stress concentration, causing the flange ring to warp and deform. This will result in a loose flange sealing surface, and the sealing ring at the filter bag opening will not be fully compacted, leading to media leakage. Overtight bolts will damage the filter bag sealing ring, while overly loose bolts will directly cause the seal to fail, thus affecting the filtration of the fluid. Therefore, a bag filter for the production of rust inhibitors is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bag filter for rust inhibitor production. It features rapid alignment and uniform force distribution, solving the problems caused by uneven force distribution and stress concentration on the flange ring if bolts are not tightened in a diagonal sequence or if bolt tightness is inconsistent. This leads to flange ring warping and deformation, resulting in poor flange sealing and incomplete compaction of the sealing ring at the filter bag opening, causing media leakage. Overly tight bolts can damage the filter bag sealing ring, while overly loose bolts directly cause seal failure, thus affecting fluid filtration.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bag filter for the production of rust inhibitors, comprising a basket mounted on the bag filter, wherein the basket is provided with a filter component and a sealing assembly; The mounting and sealing assembly includes a base component mounted on the basket, a sealing component provided on the base component, a locking component for fixing the filter component provided on the base component, and a self-locking component for controlling the locking component. The base component includes an annular seat fixedly installed on the bag filter. The annular seat has four L-shaped grooves. Four limiting blocks are fixedly installed on the outer peripheral wall of the annular seat. Four guide blocks are fixedly installed inside the annular seat. The locking component includes a clamping ring for clamping the filter component, and four L-shaped blocks are fixedly installed on the clamping ring in a centrally symmetrical distribution, with the L-shaped blocks penetrating the L-shaped groove; The self-locking component includes an outer ring threaded onto the outer surface of the annular seat, eight positioning teeth fixedly mounted on the outer ring, and the gap between two closely spaced positioning teeth is adapted to the protruding part of the L-shaped block. Several levers are fixedly mounted on the outer surface of the annular seat.

[0006] Furthermore, the sealing component includes a sealing flange, which is placed inside the annular seat, and the sealing flange has four guide grooves that are adapted to the limiting block.

[0007] Furthermore, the outer surface of the basket is provided with a slot, and the filter component includes a filter bag and a sealing ring, with the sealing ring fixedly connected to the opening of the filter bag and snapped into the slot.

[0008] Furthermore, both the sealing flange and the clamping ring have annular grooves adapted to the sealing ring on opposite sides, and both the sealing flange and the clamping ring are fitted onto the outer surface of the basket.

[0009] Furthermore, a sealing ring is installed between the sealing flange and the annular seat, and a sealing groove is provided on the opposite side of both the sealing flange and the annular seat, and the two sealing grooves are respectively adapted to the sealing ring.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This bag filter for rust inhibitor production uses a locking component and a base component to quickly fix the filter component by inserting an L-shaped block into an L-shaped groove and rotating it. This replaces the traditional flange bolt fixing method. The self-locking component works with the locking component, using two close positioning teeth in the outer ring to lock the protruding part of the L-shaped block. Combined with the threaded connection between the outer ring and the ring seat, the thread is self-locked to prevent the compression ring from loosening. This ensures that the seal does not fail during long-term operation and avoids flange deformation and failure of the filter bag sealing ring to be compacted due to uneven bolt tightening sequence or force. 2. This bag filter for rust inhibitor production uses a slotted design between the filter components and the basket, with the sealing ring engaging in the slot to form a mechanical lock. This prevents the filter bag from detaching from the basket due to fluid impact during filtration. The sealing components, base components, and sealing ring work together, with the sealing ring embedded in the sealing grooves of both components to achieve precise positioning and prevent deformation or displacement under pressure. Furthermore, the cooperation between the sealing components and locking components, with their annular grooves matching the sealing ring, creates a wrapping compression, resulting in a large contact area and uniform force distribution. This completely avoids media leakage caused by local gaps, ensuring stable sealing even under high-pressure conditions and preventing media leakage from that area. 3. This bag filter used in the production of rust inhibitors, through the cooperation of locking and self-locking components, eliminates the need for professional tools and complicated bolt diagonal tightening processes. Ordinary workers can complete the installation by simply inserting, rotating, and twisting the outer ring, thereby reducing operation training costs. Attached Figure Description

[0013] 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.

[0014] Example 1: Please refer to Figure 1-8 In this embodiment, a bag filter for producing rust inhibitors includes a basket 1 mounted on the bag filter, and a filter component 2 and a sealing assembly 3 are provided on the basket 1.

[0015] Example 2: Please refer to Figure 1-8 Based on Embodiment 1, the sealing assembly 3 includes a base component 31 installed on the basket 1, a sealing component 32 provided on the base component 31, a locking component 33 for fixing the filter component 2 provided on the base component 31, and a self-locking component 34 for controlling the locking component 33 provided on the base component 31. The base component 31 includes an annular seat 311 fixedly installed on the bag filter. The annular seat 311 has four L-shaped grooves 312. Four limiting blocks 313 are fixedly installed on the outer peripheral wall of the annular seat 311. Four guide blocks 314 are fixedly installed inside the annular seat 311. The locking component 33 includes a clamping ring 331 for clamping the filter component 2. Four L-shaped blocks 332 are fixedly installed on the clamping ring 331 in a centrally symmetrical distribution, and the L-shaped blocks 332 penetrate the L-shaped groove 312. The self-locking component 34 includes an outer ring 341 threadedly mounted on the outer surface of the annular seat 311. Eight positioning teeth 342 are fixedly mounted on the outer ring 341, and the gap between two closely spaced positioning teeth 342 is adapted to the protruding part of the L-shaped block 332. Several toggle blocks 343 are fixedly mounted on the outer surface of the annular seat 311.

[0016] The sealing component 32 includes a sealing flange 321, which is placed inside the annular seat 311. The sealing flange 321 has four guide grooves 322 that are adapted to the limiting block 313. A sealing ring 35 is installed between the sealing flange 321 and the annular seat 311. A sealing groove 351 is provided on the opposite side of the sealing flange 321 and the annular seat 311, and the two sealing grooves 351 are adapted to the sealing ring 35 respectively. The guide grooves 322 of the sealing flange 321 are adapted to the limiting block 313 of the annular seat 311 to ensure that the sealing flange 321 is accurately aligned during installation and to avoid the sealing ring 35 from shifting. Furthermore, the multiple sealing structure of the sealing flange 321, the sealing ring 35, and the annular seat 311 improves the sealing reliability, prevents the medium from leaking from the gap between the basket 1 and the base, and enhances the static sealing effect between the sealing flange 321 and the base. Even under high pressure conditions, it can prevent the medium from leaking from this part.

[0017] It should be noted that the annular seat 311, L-shaped groove 312, and limiting block 313 in the base component 31 achieve precise guidance and positioning of each component through the L-shaped groove 312 and the limiting block 313, avoiding installation misalignment. The clamping ring 331 and L-shaped block 332 in the locking component 33 are clamped and positioned by insertion and rotation, replacing the cumbersome bolt fastening, greatly shortening the bag replacement time, and avoiding flange deformation and failure of the filter bag 21 sealing ring 22 to be compacted due to uneven bolt tightening sequence or force.

[0018] Using the above technical solution, the L-shaped block 332 of the clamping ring 331 is aligned with the L-shaped groove 312 of the annular seat 311 and pressed in. The protruding part of the L-shaped block 332 is inserted between two closely spaced positioning teeth 342. The clamping ring 331 is rotated, and the outer ring 341 is rotated, so that the outer ring 341 drives the L-shaped block 332 to rotate around the central axis of the basket 1 through the positioning teeth 342, so that the L-shaped block 332 rotates in the L-shaped groove 312 until the L-shaped block 332 can no longer rotate. Because the outer ring 341 is threadedly connected to the annular seat 311, the locking component 33 is fixed by means of thread self-locking, positioning teeth 342 and L-shaped groove 312, thereby completing the installation and sealing of the filter component 2.

[0019] Example 3: Please refer to Figure 1-8 Based on Embodiment 2, a slot 11 is provided on the outer surface of the basket 1. The filter component 2 includes a filter bag 21 and a sealing ring 22. The sealing ring 22 is fixedly connected to the opening of the filter bag 21 and is snapped into the slot 11. The sealing ring 22 of the filter bag 21 is snapped into the slot 11 of the basket 1, thereby achieving mechanical fastening between the filter bag 21 and the basket 1. The installation and positioning are more accurate, and the filter bag 21 will not be detached from the basket 1 due to fluid impact during the filtration process, thus ensuring the filtration effect.

[0020] The sealing flange 321 and the compression ring 331 are provided with annular grooves 323 that are adapted to the sealing ring 22 on opposite sides. The sealing flange 321 and the compression ring 331 are both fitted onto the outer surface of the basket 1. The sealing flange 321 and the compression ring 331 are provided with annular grooves 323 that are adapted to the sealing ring 22, so that the sealing ring 22 is wrapped and compressed, with a large contact area and uniform force, which completely avoids side leakage caused by local gaps and improves the sealing integrity.

[0021] Using the above technical solution, the sealing flange 321 is fitted onto the basket 1, so that the guide groove 322 of the sealing flange 321 is aligned with the limiting block 313 of the annular seat 311. At the same time, the sealing ring 35 is embedded into the sealing groove 351 of the sealing flange 321 and the annular seat 311 to complete the initial sealing positioning. The sealing ring 22 of the filter bag 21 is then inserted into the slot 11 of the basket 1, so that the filter bag 21 is fitted inside the basket 1, ensuring that the sealing ring 22 and the slot 11 fit tightly together.

[0022] The working principle of the above embodiments is as follows: During installation, the bag filter used for rust inhibitor production is installed by fitting the sealing flange 321 onto the basket 1, aligning the guide groove 322 of the sealing flange 321 with the limiting block 313 of the annular seat 311, and simultaneously embedding the sealing ring 35 into the sealing groove 351 of the sealing flange 321 and the annular seat 311 to complete the initial sealing positioning. Insert the sealing ring 22 of the filter bag 21 into the slot 11 of the basket 1, so that the filter bag 21 is fitted inside the basket 1, ensuring that the sealing ring 22 fits tightly with the slot 11; Align the L-shaped block 332 of the clamping ring 331 with the L-shaped groove 312 of the annular seat 311 and press it in. The annular groove 323 of the clamping ring 331 fits against the sealing ring 22, initially clamping the sealing ring 22. The protruding part of the L-shaped block 332 is inserted between two closely spaced positioning teeth 342. Rotate the clamping ring 331. Rotating the outer ring 341 causes the L-shaped block 332 to rotate around the central axis of the basket 1 via the positioning teeth 342, so that the L-shaped block 332 rotates within the L-shaped groove 312 until the L-shaped block 332 can no longer rotate. Because the outer ring 341 is threadedly connected to the annular seat 311, the locking component 33 is fixed by utilizing the thread self-locking, the positioning teeth 342, and the limiting of the L-shaped groove 312, thereby completing the installation and sealing of the filter component 2.
