Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to an epoxy resin purification device. Background Technology

[0002] Epoxy resin, as an important polymer material, is widely used in electronics, electrical engineering, coatings, adhesives and other fields. However, during the synthesis of epoxy resin, there are unreacted monomers, oligomers, catalyst residues and other by-products. These impurities can affect the curing speed, mechanical properties and chemical stability of epoxy resin. Therefore, it is necessary to purify epoxy resin efficiently.

[0003] In the prior art, epoxy resin purification equipment typically includes a reaction vessel, a filtration device, a distillation tower, and a control system. During use, epoxy resin raw materials containing impurities are added to the reaction vessel through a feed pipe, and the raw materials in the reaction vessel are pretreated by stirring and heating, so that some impurities undergo chemical reactions or are transformed into easily separable forms.

[0004] However, epoxy resin raw materials have a certain degree of viscosity and tend to adhere to the inner wall of the feed inlet during the feeding process. As the number of feedings increases, the adhered material will gradually accumulate, reducing the effective flow area of ​​the feed inlet, resulting in a slower feeding speed or even clogging of the feed inlet. Utility Model Content

[0005] The purpose of this invention is to provide an epoxy resin purification device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an epoxy resin purification device, comprising a reaction vessel, an outlet pipe and an inlet pipe fixedly connected to the surface of the reaction vessel, a fixed plate fixedly connected to the surface of the reaction vessel, a lifting plate slidably connected to the surface of the fixed plate, a shaft rotatably connected to the surface of the lifting plate, a connecting plate fixedly connected to the surface of the shaft, and a scraper provided at each end of the connecting plate, the scraper being attached to the surface of the inlet pipe.

[0007] Preferably, an insulation layer is fixedly connected to the surface of the reactor, and a heating coil is wound around the surface of the reactor, with the heating coil located between the reactor and the insulation layer.

[0008] Preferably, the fixing plate has a square plate structure, and a square groove is opened on the surface of the fixing plate. Two auxiliary rods are fixedly connected between the two sides of the square groove. A manual screw is rotatably connected to one end of the square groove. One end of the manual screw extends through to the top surface of the fixing plate and is fixedly connected to a handwheel.

[0009] Preferably, the lifting plate has a "T" shaped plate structure, with two auxiliary rods passing through round holes on the surface of the lifting plate. The surface of the lifting plate has threaded holes that are engaged with the threaded portion on the surface of the manual lead screw.

[0010] Preferably, a motor is fixedly connected to the surface of the lifting plate, and one end of the shaft passes through the top surface of the lifting plate and is connected to the output end of the motor.

[0011] Preferably, the connecting plate has a central groove on both ends of its surface. The central groove is a T-shaped circular groove. A central rod is inserted into the surface of the central groove. The central rod is a T-shaped circular plate structure. Each scraper is fixedly connected to the surface of a set of central rods.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the 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.

[0023] Example 1

[0024] Please see Figures 1 to 2 This utility model provides a technical solution: an epoxy resin purification device, including a reaction vessel 1, a discharge pipe 2 and a feed pipe 3 fixedly connected to the surface of the reaction vessel 1, a fixed plate 9 fixedly connected to the surface of the reaction vessel 1, a lifting plate 7 slidably connected to the surface of the fixed plate 9, a shaft 13 rotatably connected to the surface of the lifting plate 7, a connecting plate 14 fixedly connected to the surface of the shaft 13, and a scraper 15 respectively provided at both ends of the connecting plate 14, the scraper 15 adhering to the surface of the feed pipe 3;

[0025] Through the cooperation of scraper 15, shaft 13, center rod 16, etc., scraper 15 can closely adhere to the inner wall of feed pipe 3 to scrape off the material on its surface, reducing the risk of material residue and blockage in feed pipe 3;

[0026] By setting a fixed plate 9, a manual screw 11, and a lifting plate 7, the shaft 13 and scraper 15 can be raised and lowered, thereby separating the scraper 15 from the feed pipe 3, making it easier to clean and maintain the scraper 15 and improving maintenance efficiency.

[0027] Example 2

[0028] Please see Figures 1 to 4Based on Example 1, in order to realize the lifting and lowering of the scraper 15, a heat insulation layer 4 is fixedly connected to the surface of the reactor 1. The heat insulation layer 4 is set to reduce the heat loss from the reactor 1 to the external environment and achieve a good heat insulation effect. A heating coil 5 is wound around the surface of the reactor 1. The heating coil 5 is wound around the surface of the reactor 1 in a spiral shape. The spiral winding method can make the heating coil 5 contact the surface of the reactor 1 in a large area and evenly, thereby realizing the all-round and uniform heating of the material in the reactor 1. The heating coil 5 is located on the outer wall of the reactor 1, and the heat insulation layer 4 covers the outside of the heating coil 5.

[0029] The fixed plate 9 has a square plate structure. The fixed plate 9 can withstand various forces generated by the lifting plate 7 during movement, ensuring the stability of the entire cleaning structure during operation and avoiding the impact of shaking or displacement on the cleaning effect. The surface of the fixed plate 9 is provided with a square groove. Two auxiliary rods 10 are fixedly connected between the two sides of the square groove. The auxiliary rods 10 play a guiding role, ensuring that the lifting plate 7 maintains a stable and vertical movement trajectory when moving up and down along the thread direction of the manual screw 11. At the same time, the two auxiliary rods 10 can share part of the weight of the lifting plate 7 and the connecting parts, reducing the stress on the manual screw 11.

[0030] A manual screw 11 is rotatably connected to one end of the square channel. One end of the manual screw 11 extends through to the top surface of the fixed plate 9 and is fixedly connected to a handwheel 12. The lifting plate 7 has a "T" shaped plate structure. When the lifting plate 7 rises to the top, the scraper 15 can be separated from the feed pipe 3, which is convenient for maintenance and cleaning of the scraper 15. When the lifting plate 7 descends to the bottom, the scraper 15 contacts the inner wall of the feed pipe 3, which can scrape off the residual material on the inner wall of the feed pipe 3. Two auxiliary rods 10 pass through the round holes opened on the surface of the lifting plate 7. The surface of the lifting plate 7 is provided with threaded holes 6, which are connected to the threaded part on the surface of the manual screw 11.

[0031] Example 3

[0032] Please see Figures 1 to 5 Based on Embodiment 2, in order to clean the surface of the feed pipe 3, a motor 8 is fixedly connected to the surface of the lifting plate 7. One end of the shaft 13 passes through the top surface of the lifting plate 7 and is connected to the output end of the motor 8. The two ends of the connecting plate 14 are provided with central grooves 18. The central grooves 18 are T-shaped circular grooves. The central grooves 18 provide the range of motion for the central rod 16. The T-shaped design can prevent the central rod 16 from coming out of the central groove 18 during the movement, ensuring the stability of the connection between the scraper 15 and the connecting plate 14.

[0033] A central rod 16 is inserted into the surface of the central groove 18. The central rod 16 has a T-shaped circular plate structure. Each scraper 15 is fixedly connected to the surface of a set of central rods 16. A wedge is fixedly connected to the bottom end of the scraper 15. When the scraper 15 rotates around the feed pipe 3, the inclined surface of the wedge first contacts the feed pipe 3, thereby transferring the pressure along the wedge to the surface of the scraper 15, ensuring that the scraper 15 can enter the feed pipe 3 and fit against the inner wall of the feed pipe 3.

[0034] A spring 17 is fitted onto the surface of the center rod 16. One end of the spring 17 is fixedly connected to the surface of the center groove 18, and the other end of the spring 17 is fixedly connected to one side surface of the center rod 16. When the scraper 15 is in contact with the inner wall of the feed pipe 3, the spring 17 is in a stretched state and tends to rebound to its original state, so that the spring 17 provides continuous pressure to the scraper 15. When the scraper 15 is worn after long-term use, the spring 17 can gradually reduce its stretch length to ensure that it always fits tightly against the surface of the feed pipe 3, ensuring that the cleaning effect on the feed pipe 3 is not affected.

[0035] In actual use, after the raw material is conveyed from the feed pipe 3 into the reactor 1, the handwheel 12 is rotated. The handwheel 12 drives the manual screw 11 to rotate. During the rotation of the manual screw 11, the lifting plate 7 slides down along the surface of the fixed plate 9. The inclined plate at the bottom of the scraper 15 is gradually inserted into the feed pipe 3. After the scraper 15 is squeezed by the inner wall of the feed pipe 3, the scrapers 15 on both sides move closer to the opposite end, so that the spring 17 changes from the original state to the stretched state. Finally, the scraper 15 is inserted into the inside of the feed pipe 3 and fits against the inner wall of the feed pipe 3. Then the motor 8 is started. The motor 8 drives the shaft 13 to rotate. The shaft 13 drives the scrapers 15 at both ends to rotate against the inner wall of the feed pipe 3. The scraper 15 continuously scrapes off the material remaining on the surface of the feed pipe 3 and falls into the reactor 1.

[0036] After scraping is completed, scraper 15 stops working. Handwheel 12 is rotated in the opposite direction. Handwheel 12 drives manual screw 11 to rotate, causing lifting plate 7 to drive shaft 13 and scraper 15 to rise away from the surface of feed pipe 3. At this time, scraper 15 can be cleaned. At the same time, reaction vessel 1 starts to pre-treat raw materials.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
