[0029] 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.

[0030] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a moisture separation and filtration device for epoxy powder production, comprising a stirring tank 10, the stirring tank 10 is fixedly connected to a heating wall 11, a motor 2 is fixedly connected to the middle side of the top of the stirring tank 10, a stirring rod 3 is fixedly connected to the output end of the motor 2, a plurality of sliding rods 4 are slidably connected inside the stirring rod 3, a spring 5 is sleeved on the outer side of the sliding rod 4, a scraper rod 6 is fixedly connected to the side of the sliding rod 4 away from the stirring rod 3, an anti-blocking component is arranged at the bottom of the stirring tank 10, an air outlet pipe 7 is fixedly connected to the outer side of the stirring tank 10, an air pump 8 is arranged on the outer side of the air outlet pipe 7, and a valve 9 is arranged on the outer side of the air outlet pipe 7.

[0031] Specifically, first, open valve 2 18 to introduce epoxy powder into the mixing tank 10. Next, add ethylene dichloride, and then close valve 2 18 to ensure precise control of the adding process. Then, motor 1 2 is started to drive the stirring rod 3 to rotate, thereby driving the sliding rod 4 and the scraper rod 6 to work together. In this process, although the paint will temporarily adhere to the inner wall of the heating wall 11, the scraper rod 6 will scrape it off by continuous rotation to ensure efficiency and reduce waste. After sufficient stirring, ethylene dichloride reacts with the moisture in the epoxy powder to form an azeotrope, and its boiling point is set to 72 degrees Celsius. At this time, start the air pump 8, and extract the gas in the mixing tank 10 through the outlet pipe 7 to form a negative pressure environment in the separation tank. The heating wall 11 heats up accordingly, causing its boiling material to evaporate. After the evaporation is completed, valve 1 9 is opened to allow the volatile gas to be discharged from the mixing tank 10.

[0032] When the scraper rod 6 is worn, the spring 5 will automatically adjust to ensure that the scraper rod 6 is closely attached to the inner wall of the heating wall 11, ensuring the continuous cleaning work. In this way, the entire operation process is efficient and accurate, minimizing the loss of resources.

[0033] Reference Figure 3 The anti-blocking component includes a discharge box 12, the top of the discharge box 12 is fixedly connected to the bottom of the mixing tank 10, a rotating rod 16 is rotatably connected inside the mixing tank 10, an impeller 15 is fixedly connected to the outside of the rotating rod 16, and a motor 14 is fixedly connected to the outside of the discharge box 12.

[0034] Specifically, in order to prevent the discharge port from being blocked, the operator will open valve three 19 in a timely manner. At this time, motor two 14 is started, driving the rotating rod 16 to start rotating. The movement of the rotating rod 16 further drives the impeller 15 to rotate, forming a strong centrifugal force, so that the epoxy powder that has been evenly mixed gradually separates from the mixing tank 10 during rotation, and is affected by gravity through the discharge port and flows smoothly into the pre-prepared storage box 13. When the capacity of the storage box 13 reaches the preset threshold, in order to maintain the continuity of the system and prevent overfilling, valve three 19 and motor two 14 will be closed in time. At this time, the storage box 13 filled with epoxy powder can be safely taken out for subsequent processing or refilling to ensure the smooth progress of the entire production process. Such a design effectively manages the discharge, avoids blockage, and ensures the continuity and efficiency of production.

[0035] Reference Figure 1 - Figure 3One end of the spring 5 is fixedly connected to the outside of the stirring rod 3, and the other end of the spring 5 is fixedly connected to the outside of the scraper rod 6. The top of the stirring rod 3 is rotatably connected to the middle side of the heating wall 11, and the top of the stirring rod 3 is rotatably connected to the middle side of the stirring tank 10. A feed port 17 is fixedly connected to the right side of the top of the stirring tank 10, and a valve 2 18 is arranged inside the feed port 17. A plurality of support columns 1 are fixedly connected to the bottom of the stirring tank 10, and a non-slip pad is fixedly connected to the bottom of the support column 1. The output end of the motor 2 14 is fixedly connected to one end of the rotating rod 16, and the bottom of the motor 2 14 is slidably connected to a storage box 13, and a handle is fixedly connected to the outside of the storage box 13, and a valve 3 19 is arranged on the upper part of the outside of the discharge box 12.

[0036] Specifically, the spring 5 plays a key role in buffering and regulating in this device. Its two ends are respectively fixed on the stirring rod 3 and the scraper 6, so that the two components can move synchronously and flexibly during operation, ensuring that the scraper 6 can effectively scrape the epoxy powder on the inner wall of the stirring tank 10. The top of the stirring rod 3 is connected to the heating wall 11 and the inside of the stirring tank 10 at the same time. This design allows the transfer of heat energy and stirring to promote the mixing process of epoxy powder and dichloroethane. The feed port 17 is located at the top of the tank, and the valve 18 ensures the accurate addition of materials. The support column 1 at the bottom is provided with an anti-skid pad to ensure the stability of the stirring tank 10 during operation and prevent equipment damage caused by vibration. The motor 14 drives the rotating rod 16, which in turn drives the scraper 6 and stirring to achieve efficient mixing of epoxy powder and dichloroethane. The sliding connection storage box 13 design of the motor facilitates storage and transportation, and the handle of the storage box 13 provides operational convenience. The valve 3 19 on the discharge box 12 is used to control the discharge after the mixing is completed to prevent the discharge box 12 from being blocked, and also ensure the controllability of the discharge process.

[0037] Working principle: first open valve 2 18, then add epoxy powder into the mixing tank 10 through the feed port 17, then add ethylene dichloride into the mixing tank 10, then close valve 2 18, start motor 1 2, drive the stirring rod 3 to rotate, and then drive the sliding rod 4 to rotate, thereby driving the scraper rod 6 to rotate. During the sufficient stirring process, paint will adhere to the inner wall of the heating wall 11, and the scraper rod 6 will scrape the paint off the inner wall as it rotates, thereby achieving a cleaning effect and avoiding waste. After sufficient stirring, ethylene dichloride is mixed with the water in the epoxy powder to form an azeotrope, and the boiling point of the azeotrope is 72 degrees Celsius. Then start the air pump 8, and the air pump 8 will stir the mixing tank 11 through the outlet pipe 7. The gas inside the mixing tank 10 is extracted to form a negative pressure inside the separation tank, and then power is turned on to heat the heating wall 11 to volatilize the azeotropic substance inside the mixing tank 10, and then valve one 9 is opened to allow the volatile gas to be discharged from the mixing tank 10 through the outlet pipe 7. When the scraper rod 6 is worn, the spring 5 will compress the scraper rod 6 so that the scraper rod 6 is tightly attached to the inner wall of the heating wall 11. At this time, in order to avoid blockage of the discharge port, valve three 19 is opened, and the motor two 14 is driven to drive the rotating rod 16 to rotate, thereby driving the impeller 15 to rotate, and driving the epoxy powder to rotate. Under the action of gravity, it falls into the storage box 13. When the storage box 13 is full, the valve three 19 and the motor two 14 are closed, and the storage box 13 can be taken out.

[0038] 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.
