Technical Field
[0001] This utility model relates to the technical field of epoxy resin production equipment, specifically a filtration device for the production of methacrylic acid modified alicyclic epoxy resin. Background Technology
[0002] In the production process of methacrylic acid modified alicyclic epoxy resin, filtration devices play a crucial role in ensuring product purity. Currently, most commonly used filtration devices in the industry operate on the core principle of pressure filtration or vacuum filtration. Their basic structure includes an inlet, a filter chamber, a filter medium, an outlet, and a waste collection structure. The main task of these devices is to remove mechanical impurities, unreacted solid particles, and any foreign matter that may be mixed in during the reaction process, thereby ensuring that the modified epoxy resin has stable physicochemical properties in subsequent applications. Through long-term practice, these devices have formed relatively mature operating procedures. For example, by precisely controlling the feed pressure and flow rate, and cooperating with regular backwashing operations, stable filtration efficiency is maintained, making them a standard piece of equipment for achieving fine filtration in chemical production.
[0003] The installation and replacement of filter media in existing filtration devices are complicated. Most devices require the removal of the end cover or side flange of the filter chamber. During the disassembly and assembly process, material residue or external impurities are easily introduced, causing secondary pollution. Furthermore, as the usage time increases, local blockage will gradually occur in this area, which not only disrupts the pressure balance inside the filter chamber but also reduces the filtration speed. Utility Model Content

The bottom end of the guide plate slides against the top end of the buffer chamber via an annular slide rail, and a fine filter plate is placed inside the buffer chamber. The bottom end of the buffer chamber is provided with equally spaced guide diversion plates, which abut against the bottom end of the inner wall of the main tank. The bottom end of the buffer chamber is provided with equally spaced openings, and a control valve is installed in the pipe at the bottom end of the main tank.
[0008] By adopting the above technical solution, the threaded connection between the limiting ring frame and the supporting screen cylinder, as well as the sleeve installation of the fine filter core and the coarse filter core, simplifies the disassembly and assembly process of the filter media and reduces material residue and impurity contamination.
[0009] Preferably, the bottom end of the main tank is provided with a frustum groove, and the main tank has a drive motor inside the frustum groove.
[0010] By adopting the above technical solution, the frustum-shaped groove at the bottom of the main tank provides a stable installation space for the drive motor, ensuring the motor's stability during operation and providing reliable power support for the rotation of the buffer chamber.
[0011] Preferably, the upper end face of the sealing cover is symmetrically provided with equipment operation ports, and the equipment operation ports are provided on both sides of the feed inlet.
[0012] By adopting the above technical solution, the equipment operation ports symmetrically arranged on the sealed cover facilitate operators to observe the internal filtration status and perform maintenance operations at any time, thereby improving the operability of the device.
[0013] Preferably, the side wall of the supporting mesh cylinder has holes at equal intervals, and the diameter of the holes in the supporting mesh cylinder is larger than the diameter of the fine filter core.
[0014] By adopting the above technical solution, the diameter of the holes on the side wall of the supporting screen cylinder is larger than the diameter of the fine filter core, which can not only ensure that the filtered material passes through smoothly, but also stably support the filter core and ensure a smooth filtration process.
[0015] Preferably, the guide plate abuts against the inner wall of the main tank, and the holes in the guide plate are connected to the buffer cavity.
[0016] Using the above technical solution, the guide plate abuts against the inner wall of the main tank and the holes are connected to the buffer chamber, which can evenly guide the material into the buffer chamber, avoid material accumulation, and improve filtration efficiency.
[0017] Preferably, the bottom end of the buffer chamber is rotatably connected to the bottom of the main tank via a sealed bearing, and the center of the bottom end of the buffer chamber is keyed to the output shaft of the drive motor.
[0018] Using the above technical solution, the buffer chamber is rotatably connected to the main tank through a sealed bearing and keyed to the output shaft of the drive motor, so that the buffer chamber can rotate and use centrifugal force to reduce the adhesion of impurities and improve the filtration effect.
[0019] Preferably, the bottom end of the drive motor is engaged with the limiting base, and the limiting base is installed to the bottom opening of the main tank by bolts.
[0020] By adopting the above technical solution, the drive motor and the limit base are engaged and connected, and the limit base is installed by bolts, which enhances the installation stability of the motor, reduces the impact of operating vibration on the device, and extends the service life of the equipment.
[0021] Compared with the prior art, the beneficial effects of this utility model are: the filtration device for the production of methacrylic acid modified alicyclic epoxy resin:
[0022] 1. The limiting ring frame and the supporting screen cylinder are connected by threads in the upper opening of the main tank. When it is necessary to replace the fine filter core and the coarse filter core, it is only necessary to disassemble the threaded connection between the limiting ring frame and the supporting screen cylinder to remove the entire supporting screen cylinder from the main tank. There is no need to disassemble the sealing cover or the end cover and flange of the filter chamber, which simplifies the operation process, shortens the replacement time, and avoids secondary contamination from material residue and external impurities during disassembly and assembly. At the same time, the sleeve installation method of the fine filter core being sleeved outside the coarse filter core also makes it easy to replace one of the filter cores individually, further reducing maintenance costs.
[0023] 2. The equidistant filter holes in the guide plate can evenly distribute the pre-filtered material, preventing local accumulation of material at the top of the buffer chamber. The equidistant openings at the bottom of the buffer chamber cooperate with the guide plate to evenly guide the material filtered by the fine filter plate to the bottom of the main tank, reducing the flow resistance of the material inside the chamber. The bottom of the buffer chamber is rotatably connected to the bottom of the main tank through a sealed bearing and is driven by a drive motor. The centrifugal force generated during the rotation can effectively prevent impurities from adhering and accumulating on the inner wall of the buffer chamber and the surface of the fine filter plate, maintaining the pressure balance inside the filter chamber and ensuring the stability of the filtration speed.
[0024] 3. The double-layer filtration structure, with the fine filter core nested outside the coarse filter core, combined with the fine filter plate inside the buffer chamber, forms a three-stage filtration system, improving filtration accuracy. The diameter of the holes on the side wall of the supporting screen cylinder is larger than that of the fine filter core, ensuring smooth passage of filtered material and providing stable support for the filter core. The guide plate slides in contact with the annular slide rail at the top of the buffer chamber, ensuring stable material flow when the buffer chamber rotates. Symmetrically arranged equipment operation ports on the sealing cover allow operators to easily observe the internal filtration status and connect corresponding equipment for auxiliary operation, further enhancing the practicality and reliability of the device.

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.
[0033] Please see Figures 1-6This utility model provides a technical solution: a filtration device for the production of methacrylic acid modified alicyclic epoxy resin, including a main tank 1, a sealing cover 2, a feed inlet 3, an equipment operation port 4, a limiting ring frame 5, a supporting mesh cylinder 6, a fine filter inner core 7, a coarse filter inner core 8, a guide plate 9, a buffer chamber 10, a fine filter plate 11, a guide diversion plate 12, a drive motor 13, a limiting base 14, and a control valve 15;

The guide plate 9 is installed inside the main tank 1 so that it abuts against the inner wall of the main tank 1, and the upper end of the guide plate 9 abuts against the bottom end of the supporting mesh cylinder 6.
[0037] Place the buffer chamber 10 inside the main tank 1, ensuring that the top of the buffer chamber 10 slides into contact with the bottom of the guide plate 9 via an annular slide rail. Then, place the fine filter plate 11 inside the buffer chamber 10. Position the guide diverter plates 12 equidistantly at the bottom of the buffer chamber 10, ensuring they abut against the bottom of the inner wall of the main tank 1. Figures 2-4 As shown, the drive motor 13 is installed in the frustum groove at the bottom of the main tank 1, so that the center of the bottom of the buffer chamber 10 is keyed to the output shaft of the drive motor 13. At the same time, it is ensured that the bottom of the buffer chamber 10 is rotatably connected to the bottom of the main tank 1 through the sealed bearing. The limiting base 14 is snapped onto the bottom of the drive motor 13, and the limiting base 14 is installed and fixed to the bottom opening of the main tank 1 with bolts. The control valve 15 is installed in the pipe at the bottom of the main tank 1. Finally, the sealing cover 2 is placed on the upper opening of the main tank 1 to complete the installation of the entire device.
[0038] The bottom end of the supporting screen cylinder 6 abuts against the top end of the guide plate 9, and the guide plate 9 has equally spaced filter holes. The side wall of the supporting screen cylinder 6 has equally spaced holes, and the diameter of the holes in the supporting screen cylinder 6 is larger than the diameter of the fine filter core 7. The bottom end of the guide plate 9 slides against the top end of the buffer chamber 10 via an annular slide rail. The guide plate 9 abuts against the inner wall of the main tank 1, and the holes of the guide plate 9 communicate with the buffer chamber 10. A fine filter plate 11 is placed inside the buffer chamber 10. Guide diverting plates 12 are equally spaced at the bottom end of the buffer chamber 10, and the guide diverting plates 12... The bottom of the inner wall of the main tank 1 abuts against each other, and the bottom of the buffer chamber 10 is provided with openings at equal intervals. The bottom of the buffer chamber 10 is rotatably connected to the bottom of the main tank 1 through a sealed bearing, and the center of the bottom of the buffer chamber 10 is keyed to the output shaft of the drive motor 13. A control valve 15 is provided in the pipe at the bottom of the main tank 1. A frustum groove is provided at the bottom of the main tank 1, and the drive motor 13 is located in the frustum groove of the main tank 1. The bottom of the drive motor 13 is engaged with the limiting base 14, and the limiting base 14 is installed with bolts to the opening at the bottom of the main tank 1.
[0039] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the methacrylic acid modified alicyclic epoxy resin to be filtered enters the main tank 1 through the feed port 3 on the sealing cover 2. It first undergoes double-layer preliminary filtration through the coarse filter core 8 and fine filter core 7 in the supporting mesh cylinder 6. The coarse filter core 8 intercepts larger particle impurities, while the fine filter core 7 filters out fine impurities. The filtered material flows downward through the holes on the side wall of the supporting mesh cylinder 6 to the upper end of the guide plate 9. The filter holes in the guide plate 9 evenly distribute the material. The material enters the buffer chamber 10 through the holes. The guide plate 9 slides in contact with the annular slide rail at the top of the buffer chamber 10 to ensure that the material enters smoothly without affecting the rotation of the buffer chamber 10. The fine filter plate 11 in the buffer chamber 10 performs deep filtration on the material to remove residual small impurities.
[0040] Simultaneously, the drive motor 13 rotates, driving the buffer chamber 10 and fine filter plate 11 to rotate via the output shaft. Centrifugal force is used to accelerate filtration. The filtered material flows out through the equidistant openings at the bottom of the buffer chamber 10, is guided by the guide diversion plate 12 to the bottom of the main tank 1, and finally converges into the pipe at the bottom of the main tank 1. The quantitative discharge is achieved by controlling the opening and closing of the control valve 15. The equipment operation port 4 on the sealing cover 2 can be used to observe the internal filtration and perform related operations during use. The equipment operation port 4 can be used to place corresponding equipment probes as needed.
[0041] Working principle: When using the filtration device for the production of methacrylic acid modified alicyclic epoxy resin, the methacrylic acid modified alicyclic epoxy resin to be filtered enters the main tank 1 through the feed port 3 on the sealing cover 2. It first contacts the fine filter core 7 and the coarse filter core 8, forming a double-layer preliminary filtration structure of coarse first and fine later. This allows the material to first pass through the coarse filter core 8 to intercept larger particles of impurities, and then pass through the fine filter core 7 to filter fine impurities. The holes on the side wall of the support screen cylinder 6 allow the filtered material to flow downwards to the upper end of the guide plate 9. The filter holes in the guide plate 9 evenly distribute the material to avoid local accumulation. Then the material enters the buffer chamber 10 through the holes. The bottom end of the guide plate 9 and the top end of the buffer chamber 10 slide in contact through the annular slide rail, which not only ensures that the material enters the buffer chamber 10 smoothly, but also provides space for the rotation of the buffer chamber 10.
[0042] The fine filter plate 11 inside the buffer chamber 10 performs deep filtration of the material, further removing residual micro-impurities. At the same time, the drive motor 13 is connected to the center key at the bottom of the buffer chamber 10 through the output shaft, driving the buffer chamber 10 and the fine filter plate 11 inside to rotate. Centrifugal force is used to accelerate the filtration of the material and improve the filtration efficiency. The filtered material flows out through the equidistant openings at the bottom of the buffer chamber 10 and is guided to the bottom of the main tank 1 by the guide diversion plate 12 below. Finally, the pure material after multi-stage filtration gathers into the pipe at the bottom of the main tank 1, and quantitative discharge is achieved by opening and closing the control valve 15. The limit base 14 locks the drive motor 13 to ensure its stable operation and increases the overall practicality.
