[0002] Furan resin, usually refers to polyfuran, is a thermosetting resin composed of furan groups. This resin is widely used in the industrial field due to its excellent heat resistance, chemical resistance and mechanical strength. Furan resin has unique chemical and physical properties. In the process of preparing furan resin, impurities may be mixed in, such as solid particles, foreign particles or other impurities. These impurities may affect the quality and performance of the resin, so filtering equipment is needed.

[0003] The prior art has the following defects: some existing filtering devices use a screen to filter, but the screen method allows the furan resin raw material liquid to be filtered slowly, which results in a long filtration time and cannot improve the filtration efficiency of the furan resin liquid. At the same time, long-term filtration is likely to cause the screen to be blocked. Secondly, some filtering devices are disassembled and assembled by means of multiple bolt installations. For example, if the filter frame and the mounting bracket are offset, it is easy to cause the threaded holes to be unable to be quickly installed. Therefore, a filtering device for furan resin production is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 4The utility model provides an embodiment: a filtering device for furan resin production, comprising a filter box 1, a cover plate 2 is detachably mounted on the top of the filter box 1, the cover plate 2 is connected to the top of the filter box 1 by means of an existing installation technology, and the filter box 1 and the cover plate 2 are processed by means of an existing sealing technology, so that leakage will not occur between the filter box 1 and the cover plate 2, a delivery hose is arranged on the cover plate 2, and the furan resin raw material can be injected into the filter box 1 for filtering through an external device, a driving mechanism is arranged at the bottom end of the filter box 1 through a bracket, a connecting block 5 is arranged on the outer wall of the driving mechanism, a filter frame 6 is plugged into the left end of the connecting block 5, and the filter frame 6 A filter plate is arranged on the top, and the furan resin raw material is filtered through the filter plate. The inner wall of the filter box 1 is fixedly connected with a fixed block 7, and the fixed block 7 mainly supports and connects the entire connecting plate 11. The inner wall of the fixed block 7 is elastically connected with the rotating shaft 9 through a torsion spring 8. The outer wall of the rotating shaft 9 is hinged with the connecting plate 11 through a hinge rod 10. The top inner wall of the connecting plate 11 is elastically connected with a dredging block 13 through a reset spring 12. The upper end of the dredging block 13 is an inclined surface. When the inclined surface is squeezed, the dredging block 13 will slide along the inner wall of the connecting plate 11, and the lower end diameter of the dredging block 13 is larger than the diameter of the top inclined surface, so that only the upper end of the dredging block 13 can penetrate the filter plate.

[0033] Reference Figure 3 , Figure 4 and Figure 6 The inner wall of the connecting block 5 is elastically connected with a baffle 15 through a movable spring 14. The inner wall of the connecting block 5 is fixedly connected to one end of the movable spring 14. When the baffle 15 rotates, the movable spring 14 is compressed. When resetting, the elastic force of the movable spring 14 is used to reset the baffle 15. The other end of the movable spring 14 is fixedly connected to the outer wall of the baffle 15. The baffle 15 is rotatably connected to the inner wall of the connecting block 5. The baffle 15 contacts the top end of the filter frame 6. A threaded hole is provided on the baffle 15. The top end of the filter frame 6 is provided with a threaded hole matching the baffle 15. The baffle 15 and the filter frame 6 can be fastened by bolts.

[0034] Reference Figure 1 , Figure 2 and Figure 4The inner wall of the fixed block 7 is fixedly connected to one end of the torsion spring 8. At this time, the torsion spring 8 is in a fully compressed state. When resetting, the torsion spring 8 will rotate and reset with the rotating shaft 9. The other end of the torsion spring 8 is fixedly connected to the outer wall of the rotating shaft 9. The rotating shaft 9 penetrates and is rotatably connected to the inner wall of the fixed block 7. The outer wall of the rotating shaft 9 is fixedly connected to one end of the hinged rod 10. Due to the certain length of the hinged rod 10, when the rotating shaft 9 rotates one end of the hinged rod 10 to the right, the hinged rod 10 at the other end will push the connecting plate 11 to move upward along the trajectory. On the contrary, when the rotating shaft 9 rotates one end of the hinged rod 10 to the left, the hinged rod 10 at the other end will slide along the connecting plate 11. The other end of the hinged rod 10 is hinged to the bottom end of the connecting plate 11, and the connecting plate 11 is slidably connected to the inner wall of the filter box 1. The inner wall of the filter box 1 is provided with a notch, which can allow the connecting plate 11 to slide along the notch to ensure that the connecting plate 11 is in a vertical state. The top inner wall of the connecting plate 11 The wall is fixedly connected to one end of the return spring 12. When the dredging block 13 moves downward, the return spring 12 will be compressed. When resetting, the elastic force of the return spring 12 will bring the dredging block 13 to reset. The other end of the return spring 12 is fixedly connected to the bottom end of the dredging block 13. The dredging block 13 is slidably connected to the inner wall of the connecting plate 11, and the filter frame 6 is slidably connected to the inner wall of the filter box 1. A vertical slot is provided on the inner wall of the filter box 1, so that the filter frame 6 can be removed from the filter box 1 without being blocked. The driving mechanism includes a motor 3, which is arranged at the bottom end of the filter box 1 through a bracket. A screw rod 4 is fixedly connected to the output end of the motor 3. When the screw rod 4 rotates, the connecting block 5 can move vertically back and forth. The screw rod 4 is a prior art and will not be described in detail here. The outer wall of the screw rod 4 is threadedly connected to the inner wall of the connecting block 5. The connecting block 5 matches the screw rod 4, so that the connecting block 5 can move vertically along the outer wall of the screw rod 4.

[0035] Working principle: First, when the furan resin raw material needs to be filtered, the furan resin raw material liquid is transported into the filter box 1 through the hose through the external device, and then the motor 3 is started to rotate the screw rod 4, so that the connecting block 5 moves the filter frame 6 upward. Since the inner wall of the bottom end of the filter box 1 is in a sealed state, the upward movement of the filter frame 6 will cooperate with the inner wall of the bottom end of the filter box 1 to squeeze the furan resin raw material liquid, so that the furan resin raw material liquid is quickly filtered from the filter plate on the filter frame 6. At the same time, when the filter frame 6 moves upward, the reverse elastic force of the torsion spring 8 drives the rotating shaft 9 and the hinge 6 to move upward. The connecting rod 10 and the connecting plate 11 rotate to the right, so that the connecting plate 11 is now located at the right end of the filter frame 6, and the dredging block 13 is plugged into the filter plate hole at the right end of the filter frame 6. When the connecting block 5 moves the filter frame 6 downward, the filter plate hole will squeeze the inclined surface of the dredging block 13, so that the dredging block 13 moves downward and compresses the reset spring 12. When the dredging block 13 coincides with the next filter plate hole, the reverse elastic force of the reset spring 12 is used to reset the dredging block 13, so that the dredging block 13 is continuously plugged into the filter plate hole to reduce the blockage caused by the filter plate.

[0036] When it is necessary to replace or clean the filter plate of the filter frame 6, it is only necessary to rotate the motor 3 with the screw rod 4, and let the connecting block 5 move the filter frame 6 upward to the highest height close to the inner wall position at the bottom end of the cover plate 2, and then stop the motor 3 to position the filter frame 6, and then release the bolts fixing the baffle 15 and the filter frame 6, and then rotate the baffle 15 and compress the movable spring 14 so that the baffle 15 no longer blocks the filter frame 6 from moving out from the outer wall of the baffle 15. When it is necessary to install the filter frame 6, it is only necessary to connect the filter frame 6 with the baffle 15, and then loosen the baffle 15 and use the reverse elastic force of the movable spring 14 to rotate and reset the baffle 15, so that the threaded hole on the baffle 15 quickly coincides with the top of the filter frame 6, and finally the baffle 15 and the filter frame 6 are fastened by bolts to complete the disassembly and assembly.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
