DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following specifically introduces the utility model in combination with the attached drawings and specific embodiments.

[0022] Embodiment: An epoxy resin coating production device with a filtering function, as Figures 1-5As shown in the figure, it includes a housing 1, a support frame 2, a sealing cover 3, a flange 301, a sandwich layer 4, a protective shell 5, a filter shell 6, a motor 7, a connecting shaft 8, a shaft seal 9, a stirring blade 10, a connecting rod 11, a scraper 12, a feed pipe 13, a discharge hopper 18, a control valve 19, a filter bag 20 and a filter plate 22. The outer wall of the middle part of the housing 1 is welded with the support frame 2. The sealing cover 3 is placed on the top of the housing 1. The inner wall of the upper part of the housing 1 is flange-connected with the filter plate 22. The outer wall at the joint of the top of the housing 1 and the bottom of the sealing cover 3 is bolt-connected with the flange 301. A sandwich layer 4 is provided on the housing wall of the housing 1. The bottom of the housing 1 is welded with the protective shell 5 and the filter shell 6. The protective shell 5 is located outside the filter shell 6. The protective shell 5 and the filter shell 6 are designed as a concentric circle structure, and an annular space is formed between the shells of the protective shell 5 and the filter shell 6. The motor 7 is installed on the top of the support frame 2 by bolts. A connecting shaft 8 is key-connected to the output shaft of the motor 7. The connecting shaft 8 extends into the housing 1. The upper part of the connecting shaft 8 is mechanically sealed with the shaft seal 9. The bottom of the shaft seal 9 is in close contact with the top of the sealing cover 3. The stirring blade 10 is key-connected to the middle part of the connecting shaft 8. Six connecting rods 11 are key-connected to the lower part of the connecting shaft 8. A scraper 12 is key-connected to each connecting rod 11. The scraper 12 and the stirring blade 10 are both located inside the housing 1. The left side of the sealing cover 3 is connected and communicated with the feed pipe 13. The bottom of the protective shell 5 is connected and communicated with the discharge hopper 18. The control valve 19 is quickly installed at the bottom of the discharge hopper 18. The filter bag 20 is connected by hanging ears inside the discharge hopper 18. The filter bag 20 adopts a disposable design and is made of a synthetic fiber material with high chemical stability.

[0023] As Figures 1-3 shown in the figure, it further includes an observation sight glass 14, a pressure detector 15, a water guide pipe 16, a water outlet pipe 17 and a heating pipe 21. The observation sight glass 14 is bolt-connected to the front side of the sealing cover 3. The pressure detector 15 is bolt-connected to the right side of the sealing cover 3. The left side of the upper part of the housing 1 is connected and communicated with the water guide pipe 16. The right side of the lower part of the housing 1 is connected and communicated with the water outlet pipe 17. The heating pipe 21 is bolt-connected inside the sandwich layer 4.

[0024] First, place the device horizontally in the designated working area. After the device is stably placed, inject sufficient distilled water through the water conduit 16 to fill the interlayer 4 with distilled water. After the interlayer 4 is filled with distilled water, seal the water conduit 16 and the water outlet pipe 17, and at the same time ensure that there is no air residue in the interlayer 4 at this time. Then activate the heating tube 21 to make it in the working state. After the heating tube 21 heats up, it generates heat and transfers the heat to the distilled water. At this time, the distilled water serves as a heat transfer medium to heat the outer shell 1, causing the outer shell 1 to heat up and maintain a certain temperature. Then start the motor 7. At this time, the output shaft of the motor 7 drives the connecting shaft 8 to rotate, and the connecting shaft 8 drives the stirring blade 10 and the scraping plate 12 to rotate. Subsequently, fill the epoxy resin and the curing agent into the outer shell 1 through the feed pipe 13. At this time, both the epoxy resin and the curing agent first come into contact with the filter plate 22. The filter plate 22 filters out some larger impurities mixed in the epoxy resin and the curing agent. The larger impurities remain on the top of the filter plate 22, and the epoxy resin and the curing agent fall into the outer shell 1. At this time, the first filtration of the epoxy resin and the curing agent is completed. Subsequently, the stirring blade 10 first continuously stirs the epoxy resin and the curing agent to make the epoxy resin and the curing agent evenly distributed and obtain a good mixing effect. At the same time, when the epoxy resin and the curing agent are being stirred, because the outer shell 1 is in a state of being heated up, and the epoxy resin has the characteristic of high viscosity, so when the epoxy resin and the curing agent come into contact with the outer shell 1, the epoxy resin and the curing agent will be indirectly heated by the outer shell 1. At this time, the viscosity of the epoxy resin decreases, making it easier for the epoxy resin to be mixed with the curing agent, and the fluidity of the epoxy resin and the curing agent that are fully stirred evenly is improved. Subsequently, the epoxy resin coating flows into the filter housing 6. Because the scraping plate 12 is driven by the connecting shaft 8 to rotate continuously, and the scraping plate 12 is inclined, so when the scraping plate 12 comes into contact with and moves on the inner surface of the filter housing 6, the scraping plate 12 will scrape off the epoxy resin coating on the inner surface of the filter housing 6. The scraped-off epoxy resin coating is guided into the annular space between the protective housing 5 and the filter housing 6, that is, the filter medium of the filter housing 6 allows the relatively pure epoxy resin coating to pass through, while the larger particle impurities are retained inside the filter housing 6. At this time, the second filtration of the epoxy resin coating is completed. Also, because the bottom opening of the protective housing 5 is connected and communicated with the hopper 18, the epoxy resin coating will first flow into the filter bag 20 and be filtered by the filter bag 20 with a small aperture. At this time, the epoxy resin coating that has been filtered flows into the discharge port of the hopper 18, while the extremely fine impurities filtered out remain in the bag filter. At this time, the epoxy resin coating is in a state of relatively high purity. Subsequently, the staff should open the control valve 19 and place other containers for holding the epoxy resin coating directly below the hopper 18, so that the epoxy resin coating flows into the holding container under its own gravity.

[0025] When the epoxy resin and the curing agent react inside the outer shell 1, the staff can observe the reaction condition of the materials inside the outer shell 1 through the sight glass 14. At the same time, because when the epoxy resin and the curing agent inside the outer shell 1 are stirred and mixed, certain heat, etc. will be released, which may cause the pressure value inside the outer shell 1 to change within a certain range. At this time, the staff can understand the pressure value inside the outer shell 1 through the pressure detector 15. Through the observation function of the sight glass 14 and the detection function of the pressure detector 15, the staff can better grasp the reaction condition of the materials inside the outer shell 1, so as to make corresponding adjustments in time by the staff. When the impurities on the top of the filter plate 22 and inside the filter housing 6 accumulate to a certain extent, the staff can first suspend the production of epoxy resin paint, that is, first turn off the motor 7 and the heating pipe 21. The output shaft of the motor 7 no longer drives the stirring blade 10 and the scraping plate 12 to rotate, and the heating pipe 21 no longer heats the distilled water inside the interlayer 4. Subsequently, the staff removes the flange 301 with other tools, so that the connecting shaft 8 is temporarily disengaged from the key connection with the output shaft of the motor 7. Then the sealing cover 3 is removed. At this time, the staff first cleans the impurities on the filter plate 22, then removes the filter plate 22, and then removes components such as the connecting shaft 8 and the stirring blade 10. Finally, the impurities inside the outer shell 1 are cleaned. After ensuring that the impurities inside the outer shell 1 and on the filter plate 22 are both cleaned, the removed components are installed back to the initial state again. When the impurities inside the filter bag 20 accumulate to a certain extent and there is a situation of blocking the discharge of the epoxy resin paint, the staff can first remove the hopper 18, and then take out the filter bag 20 and the impurities inside it together. Subsequently, the impurities inside the filter bag 20 are cleaned, and the clean filter bag 20 is returned to the initial state, or a brand-new filter bag 20 is replaced for filtering the epoxy resin paint. When the device has been used for a long time, the distilled water in the interlayer 4 will experience repeated heating and cooling, so the impurities in the distilled water will deposit in the interlayer 4. At this time, the staff can open the water outlet pipe 17, and the distilled water flows out through the water outlet pipe 17, driving a certain amount of impurities to flow out of the interlayer 4. If the impurities in the interlayer 4 cannot be cleaned completely, the staff can inject clean water into the interlayer 4 again through the water guide pipe 16, and at the same time, the water outlet pipe 17 remains in the water outlet state. Repeat the water injection and water discharge until the impurities in the interlayer 4 are cleaned completely. If it is necessary to use the device again for the production of epoxy resin paint, repeat the above steps.

[0026] The above has introduced this application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application; at the same time, for those of ordinary skill in the art, according to the idea of this application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to this application.
