Description

Technical Field

[0001] This utility model relates to the field of filter equipment technology, and in particular to a filter assembly. Background Technology

[0002] Agricultural and sideline food processing encompasses multiple sub-sectors such as oils, dairy products, fruits and vegetables, and condiments. Filtration is a crucial step throughout the entire process, from raw material handling and intermediate product processing to finished product refining. For example, edible oil refining requires multi-stage filtration to remove residue, colloids, and pigments, while dairy product processing requires microfiltration membranes for sterilization and protein separation.

[0003] Most existing bag filter assemblies are fixed and installed using positioning structures such as clamps or semi-circular retaining rings. In filter assemblies that use two symmetrical sets of semi-circular retaining rings for fixing, the locking and splicing structure of the two semi-circular retaining rings is mostly composed of multiple separate threaded locking parts (such as nuts or bolts). Although threaded locking parts are simple in structure, versatile, and inexpensive, when multiple separate threaded locking parts are used together to lock and position the two semi-circular retaining rings for fixing the bag filter assembly, it is necessary to tighten and loosen multiple threaded locking parts step by step in both directions to unlock or lock the bag filter assembly and disassemble it. This operation is relatively cumbersome and inconvenient, indirectly reducing the efficiency of bag filter assembly disassembly and assembly. Utility Model Content

[0004] In view of this, the present invention provides a filter assembly to solve the problem that it is cumbersome and inconvenient to disassemble and assemble a bag filter assembly by sequentially turning multiple threaded locking parts in both directions.

[0005] The technical solution proposed by this utility model is as follows: a filter assembly, specifically including a cage-shaped frame and a filter bag, wherein the filter bag is fitted around the outer periphery of the cage-shaped frame; a feed cylinder is welded to the top of the cage-shaped frame, and two semi-circular retaining rings are symmetrically slidably installed in the space on both sides of the feed cylinder, with the two semi-circular retaining rings pressing against the top opening of the filter bag; two sliding mounting parts are symmetrically welded to the two semi-circular retaining rings; a drive ring is rotatably installed around the outer periphery of the feed cylinder, and two connecting rods are rotatably connected between the drive ring and the two sliding mounting parts; a tightening bolt is threaded through the peripheral wall of the drive ring, and the head end of the tightening bolt presses against the outer periphery of the feed cylinder; two symmetrically distributed arc-shaped force-bearing blocks are integrally formed at the opening end of the semi-circular retaining rings, and two L-shaped retaining plates are symmetrically welded to the outer periphery of the feed cylinder, with two symmetrically distributed arc-shaped guide blocks integrally formed on the L-shaped retaining plates, and the arc-shaped guide surfaces of the arc-shaped force-bearing blocks sliding against the arc-shaped guide surfaces of the arc-shaped guide blocks.

[0006] Furthermore, two rectangular support frames are symmetrically welded to the outer periphery of the feed cylinder below the drive ring, and two transverse guide shafts are welded at intervals inside the rectangular support frames.

[0007] Furthermore, the sliding mounting component is integrally formed from a rectangular slider and two spaced connecting blocks. The rectangular slider slides in cooperation with the two horizontal guide shafts on the corresponding side and the internal space of the rectangular support frame. The first end of the connecting block is fixedly connected to a semi-circular retaining ring. The two ends of the connecting rod are respectively rotatably connected to the outer periphery of the rectangular slider and the drive ring.

[0008] Furthermore, a limiting ring is integrally formed at the top of the feed cylinder, and the drive ring is located between the limiting ring and the rectangular support frame.

[0009] Furthermore, it also includes two symmetrically arranged T-shaped brackets, with the opposite ends of the two rectangular support frames welded and fixed to the top parts of the two T-shaped brackets respectively.

[0010] The filter assembly provided by this utility model has the following beneficial effects: First, the drive ring, two connecting rods, two sliding mounting parts, and two semi-circular retaining rings are connected to form a modified double-crank slider mechanism. Through this mechanism, the forward and reverse twisting of the drive ring can drive the two sliding mounting parts and the two semi-circular retaining rings to slide towards or away from each other, controlling the two semi-circular retaining rings to synchronously press against or separate from the top opening of the filter bag, completing the unlocking or locking of the filter bag in one go. This facilitates the disassembly and assembly of the filter bag. Compared with the existing technology that uses multiple separate independent threaded locking parts (such as nuts or bolts) to lock and position the two semi-circular retaining rings to achieve fixed installation of the filter bag, this eliminates the trouble of having to twist and loosen multiple threaded locking parts step by step to unlock or lock the filter bag and disassemble and assemble it. The operation is simpler and helps to improve the efficiency of filter bag disassembly and assembly.

[0011] Second, through the guiding effect of the arc-shaped force-bearing block and the arc-shaped guide surface of the arc-shaped guide block, the open end of the semi-circular retaining ring away from the sliding mounting part can be pushed and squeezed towards the feed cylinder, so as to tightly press the two parts of the open end of the semi-circular retaining ring against the outer circumference of the feed cylinder, and to achieve stable and tight fixation of the filter bag. Compared with the existing technology where the open end of the semi-circular retaining ring lacks the necessary guiding pressure to increase the clamping and fixing force, this can avoid the semi-circular retaining ring being in a relaxed and low-pressure state due to its distance from the sliding mounting part that applies pressure to it when there is no guiding pressure, thus failing to effectively and fully fix the filter bag. This helps to improve the clamping and fixing effect of the semi-circular retaining ring on the filter bag. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this 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, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please refer to Figures 1 to 6 Example 1: This embodiment proposes a filter assembly, including a cage-shaped frame 3 and a filter bag 2. The outer periphery of the cage-shaped frame 3 is covered and fitted with a filter bag 2 whose shape is suitable for it. A feed cylinder 301 is welded to the top of the cage-shaped frame 3. Two semi-circular retaining rings 6 are symmetrically slidably installed in the spaces on both sides of the feed cylinder 301. The two semi-circular retaining rings 6 press against and abut against the top opening of the filter bag 2 to clamp and fix the top opening to the outer periphery of the feed cylinder 301. Two sliding mounting parts 601 are symmetrically welded to the middle part of the two semi-circular retaining rings 6. A drive ring 4 is rotatably installed on the outer periphery of the feed cylinder 301. The drive ring 4 is connected to the two sliding mounting parts 601. The rotating connection has two parallel inclined connecting rods 402. A tightening bolt 401 is threaded through the peripheral wall of the drive ring 4. The head of the tightening bolt 401 is in contact with the outer periphery of the feed cylinder 301. The open end of the semi-circular retaining ring 6 has two symmetrically distributed arc-shaped force blocks 602 integrally formed. The part of the outer periphery of the feed cylinder 301 below the drive ring 4 has two L-shaped retaining plates 302 symmetrically welded. The inner side of the bottom part of the L-shaped retaining plate 302 has two symmetrically distributed arc-shaped guide blocks 3021 integrally formed. The arc-shaped guide surface of the arc-shaped force block 602 slides and abuts against the arc-shaped guide surface of the arc-shaped guide block 3021.

[0018] Preferably, two rectangular support frames 5 are symmetrically welded to the outer periphery of the feed cylinder 301 below the drive ring 4, and two horizontally placed guide shafts 501 are welded at intervals inside the rectangular support frames 5.

[0019] Preferably, the sliding mounting component 601 is integrally formed of a rectangular slider 6011 and two spaced connecting blocks 6012. The rectangular slider 6011 slides in cooperation with the two horizontally placed guide shafts 501 on the corresponding side and the internal space of the rectangular support frame 5. The first end of the connecting block 6012 is fixedly connected to the semi-circular retaining ring 6. The two ends of the connecting rod 402 are respectively rotatably connected to the rectangular slider 6011 and the outer periphery of the drive ring 4.

[0020] Implementation 2: This embodiment is based on Implementation 1, but with the following additions: This embodiment includes two symmetrically arranged T-shaped supports 1. A limiting ring 3011 is integrally formed at the top of the feed cylinder 301. A drive ring 4 is located between the limiting ring 3011 and the rectangular support frame 5. The opposite ends of the two rectangular support frames 5 are welded and fixed to the top parts of the two T-shaped supports 1 respectively. The filter bag 2 is made of PP or nylon material, with a precision of 5-200μm, and is suitable for batch filtration and clarification of large-flow fruit and vegetable juices. The single bag processing capacity can reach 1-10m³. 3 / h.

[0021] The working principle, specific details, implementation steps, functions and interrelationships of the features in the above embodiments, and the roles these features play in realizing this technical solution will be described and explained in detail below: In use, align the top opening of the feed cylinder 301 with the juice outlet on the production line for producing fruit and vegetable juice. Place a clear liquid container directly below the filter bag 2 to collect the filtered clear fruit and vegetable juice. The coarse fruit and vegetable juice flowing down the production line into the filter bag 2 passes through the filter bag 2 under the combined action of its own weight and internal liquid pressure to form clear fruit and vegetable juice. After flowing out of the filter bag 2, the clear fruit and vegetable juice drips down into the clear liquid container for temporary storage, to be processed by subsequent fine filtration.

[0022] The drive ring 4, two connecting rods 402, two sliding mounting parts 601, and two semi-circular retaining rings 6 are connected to form a deformed double-crank slider mechanism. Through this mechanism, the forward and reverse rotation of the drive ring 4 can drive the two sliding mounting parts 601 and the two semi-circular retaining rings 6 to slide towards or away from each other, controlling the two semi-circular retaining rings 6 to simultaneously press against or separate from the top opening of the filter bag 2, thus unlocking or locking the filter bag 2 in one go. This facilitates the disassembly and assembly of the filter bag 2. Compared with the existing technology that uses multiple separate threaded locking parts (such as nuts or bolts) to lock and position the two semi-circular retaining rings 6 to achieve fixed installation of the filter bag 2, this eliminates the trouble of having to turn multiple threaded locking parts forward and reverse step by step to unlock or lock the filter bag 2 and disassemble and assemble it. The operation is simpler and helps to improve the efficiency of disassembly and assembly of the filter bag 2.

[0023] Through the guiding effect of the arc-shaped force-bearing block 602 and the arc-shaped guide surface of the arc-shaped guide block 3021, the open end of the semi-circular retaining ring 6 away from the sliding mounting part 601 can be pressed and pushed towards the feed cylinder 301, so that the two parts of the open end of the semi-circular retaining ring 6 are tightly pressed against the outer periphery of the feed cylinder 301, thus achieving a stable and tight fixation of the filter bag 2. Compared with the existing technology where the open end of the semi-circular retaining ring 6 lacks the necessary guiding pressure to increase the clamping and fixing force, this can avoid the semi-circular retaining ring 6 being in a relaxed and low-pressure state due to its distance from the sliding mounting part 601 that applies pressure to it when there is no guiding pressure, thus failing to effectively and fully fix the filter bag 2. This helps to improve the clamping and fixing effect of the semi-circular retaining ring 6 on the filter bag 2.
