Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a material filtration component and an unsaturated resin purification device. Background Technology

[0002] In the synthesis and production of unsaturated resins, purification mainly involves removing impurities such as unreacted raw materials, oligomers, catalyst residues, and volatile organic compounds to improve the purity, stability, and performance of the resin. Separation is achieved by utilizing the difference in solubility between unsaturated resins and impurities in solvents. The resin is dissolved in an appropriate solvent, and by adjusting the temperature, solvent ratio, or adding an extractant, impurities are precipitated or transferred to another phase. Separation is then achieved through filtration equipment.

[0003] Traditional filtration devices mostly employ static filtration, where filter bags are fixed within a frame, and unsaturated resin relies on gravity to naturally permeate the filter bags to complete the filtration. This type of device has significant drawbacks: impurities easily accumulate on the surface of the filter bags, leading to a gradual increase in filtration resistance and a significant decrease in filtration efficiency over time; frequent shutdowns for cleaning or replacement of filter bags are required to maintain filtration effectiveness, increasing production costs and affecting production continuity; and the slow resin flow rate in static filtration mode limits the throughput per unit time, making it difficult to meet the demands of large-scale production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where traditional filtration devices often employ static filtration methods, with filter bags fixed within a frame and unsaturated resin relying on gravity to naturally permeate the filter bags to complete filtration. Therefore, this invention proposes a material filtration component and an unsaturated resin purification device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A material filtration assembly and unsaturated resin purification device includes a filter cartridge. An installation ring is fixed to the surface of the filter cartridge. Four support legs are fixed to the bottom end of the installation ring. A first groove is formed at the top end of the installation ring. A sealing cap is fixed to the top end of the first groove. A rotating ring rotates within the first groove. A connecting ring is fixed to the top end of the rotating ring by bolts. A stainless steel filter frame is fixed within the connecting ring. Multiple communicating grooves are formed within the stainless steel filter frame for discharging unsaturated resin. A filter bag for filtering the unsaturated resin is provided within the stainless steel filter frame.

[0007] To expand the filter bag, a cross support is fixed inside the filter bag. A set of compression components for fixing the filter bag is provided between the cross support and the stainless steel filter frame. At the same time, to increase the filtration efficiency of the filter bag, a set of rotating components is provided inside the mounting ring. The rotating components are used to drive the filter bag and the unsaturated resin inside the filter bag to rotate, thereby accelerating filtration.

[0008] In one possible design, the extrusion assembly includes a threaded connecting ring fitted onto the surface of a stainless steel filter frame. The surface of the stainless steel filter frame has external threads. The threaded connecting ring is threaded onto the surface of the stainless steel filter frame. A clamping gap is formed between the stainless steel filter frame and the threaded connecting ring. The edge of the filter bag is located within the clamping gap.

[0009] The threaded connecting ring can be tightened to clamp and position the filter bag in conjunction with the stainless steel filter frame, while the threaded connecting ring can be installed to fix the position of the cross support and open the filter bag.

[0010] In one possible design, the rotating assembly includes a first gear rotating within a first groove, a second gear fixed to the surface of the rotating ring, the second gear meshing with the first gear, and a drive motor fixed to the top of the sealing cover, the drive motor being fixedly connected to the first gear via a coupling;

[0011] The system works by starting a drive motor to rotate the first gear, which in turn drives the second gear to rotate. The second gear, through a rotating ring, drives the stainless steel filter frame and filter bag to rotate, thereby accelerating the filtration efficiency of the unsaturated resin.

[0012] In one possible design, a fixed threaded ring is fixed to the top of the sealing cover, and a cover plate is threadedly connected to the surface of the fixed threaded ring. An inlet for feeding material is fixed inside the cover plate and connected to the stainless steel filter frame.

[0013] In one possible design, a discharge pipe is fixed inside the filter cartridge for discharging the filtered unsaturated resin.

[0014] In this application, turning the threaded connecting ring can be used with the stainless steel filter frame to clamp and position the filter bag, and installing the threaded connecting ring can fix the position of the cross support to open the filter bag.

[0015] The drive motor is started to rotate the first gear, which in turn drives the second gear to rotate. The second gear, through a rotating ring, drives the stainless steel filter frame and filter bag to rotate, thereby accelerating the filtration efficiency of the unsaturated resin.

[0016] Beneficial effects: In this utility model, the material filtration component and unsaturated resin purification equipment achieve dynamic filtration through the rotating component. Impurities are thrown towards the inner wall of the filter bag to form a dynamic filtration layer, avoiding the problem of impurities accumulating and clogging on the surface of the filter bag in traditional static filtration. The filtration efficiency is improved, and there is no need for frequent shutdowns for cleaning.

[0017] In this utility model, the material filtration component and unsaturated resin purification equipment have a simplified filter bag installation process with an extrusion component: the threaded connecting ring is threadedly engaged with the stainless steel filter frame, and the edge clamping and positioning of the filter bag and the fixing of the cross support can be completed by rotating the threaded connecting ring, which significantly improves the ease of operation.

[0023] In one embodiment: Refer to Figures 1-3 A material filtration assembly and unsaturated resin purification device are disclosed, which are applied in the field of filtration equipment technology. The assembly includes a filter cartridge 1, a mounting ring 2, a sealing cover 3, and an internal filtration component. The filter cartridge 1 is a hollow cylinder with the mounting ring 2 welded and fixed at the top opening. Four supporting legs 4 are evenly distributed at the bottom of the mounting ring 2 to support the entire assembly. A first groove 12 is formed at the top of the mounting ring 2, and the sealing cover 3 is fixed to the top of the first groove 12 by bolts. A rubber sealing ring is provided on the contact surface between the sealing cover 3 and the mounting ring 2 to ensure a tight seal.

[0024] The stainless steel filter frame 8 is a cylindrical frame fixed inside the connecting ring 10. It has external threads on its surface and 12 evenly distributed connecting grooves inside for unsaturated resin discharge. The filter bag 7 is made of polyester fiber and is fitted inside the stainless steel filter frame 8. The edges of the filter bag 7 are fixed by an extrusion assembly. The extrusion assembly consists of a threaded connecting ring 9, the inner diameter of which matches the outer diameter of the stainless steel filter frame 8. Tightening the threaded connecting ring 9 causes it to move downwards along the threads on the surface of the stainless steel filter frame 8, forming a clamping gap with the stainless steel filter frame 8. The edges of the filter bag 7 are clamped within this gap for positioning. The cross support 6 is made of stainless steel and fixed inside the filter bag 7. Its top is pressed and fixed by the threaded connecting ring 9 to ensure that the filter bag 7 remains open.

[0025] The rotating assembly is located inside the mounting ring 2. The first gear 13 is rotatably mounted in the first groove 12 via a bearing. The rotating ring 15 is rotatably mounted in the first groove 12 via a bearing. A second gear 14 is welded to the surface of the rotating ring 15, and the second gear 14 meshes with the first gear 13 for transmission. A drive motor 11 is fixed to the top of the sealing cover 3. The output shaft of the drive motor 11 is connected to the first gear 13 via a coupling. The drive motor 11 rotates at a speed of 120 r / min. When the drive motor 11 is started, the first gear 13 drives the second gear 14 to rotate. The second gear 14, through the rotating ring 15, drives the stainless steel filter frame 8 to rotate. The filter bag 7 rotates synchronously with the stainless steel filter frame 8, causing centrifugal force to be generated in the unsaturated resin inside, accelerating filtration.

[0026] In another embodiment: Refer to Figures 1-3 Improvements based on Example 1: A fixed threaded ring 18 is welded to the top of the sealing cap 3, and a cover plate 17 is threadedly connected to the surface of the fixed threaded ring 18. An inlet 16 is opened in the center of the cover plate 17, which is connected to the inside of the stainless steel filter frame 8 through a pipe for conveying the unsaturated resin to be filtered. A discharge pipe 5 is welded to the center of the bottom of the filter cylinder 1 for discharging the filtered unsaturated resin, and a valve is installed at the end of the discharge pipe 5 to control the flow rate.
