Technical Field

[0001] This utility model relates to the technical field of degassing kettles, and in particular to an epoxy resin degassing kettle. Background Technology

[0002] Degassing reactors are widely used for degassing liquid slurries containing bubbles in food, chemical and other industries. Existing slurry degassing generally adopts chemical methods by adding defoamers or physical methods by vacuum degassing. Chemical methods require the addition of defoamers.

[0003] Existing epoxy resin degassing kettles, such as the epoxy resin injection molding production degassing kettle disclosed in utility model patent application number 201920812082.8, mainly include a support frame. Two support frames are provided at both ends of the lower surface of the support frame. An outer tank of the degassing kettle is provided on the upper surface of the support frame. An operating body of the degassing kettle is provided on the upper surface of the outer tank of the degassing kettle. The operating body of the degassing kettle is connected to the outer tank of the degassing kettle by bolts. An inner protective tank is provided inside the outer tank of the degassing kettle. In use, the inner protective tank is placed inside the outer tank of the degassing kettle so that the side plate is engaged inside the placement groove. The second bolt is screwed in to fix the side plate to the outer tank of the degassing kettle. Then, the first bolt is screwed in to connect the outer tank of the degassing kettle to the side of the inner protective tank, thus fixing the inner protective tank to the outer tank of the degassing kettle.

[0004] However, most existing degassing kettles use static vacuum degassing or ordinary stirring degassing, which have poor degassing effect, long degassing time, and high viscosity of epoxy resin after degassing, making it difficult to discharge and easy to remain in the device. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an epoxy resin degassing kettle that not only enhances the degassing effect, improves the degassing efficiency, and shortens the degassing time by combining stirring, heating, and vacuuming, but also facilitates the expulsion of epoxy resin residue in the device, thus avoiding epoxy resin residue in the device.

[0006] This utility model discloses an epoxy resin degassing kettle, comprising a degassing kettle; it also includes a sealing mechanism, a stirring mechanism, a heating mechanism, and an air extraction mechanism.

The operator adds epoxy resin to the degassing kettle through the sealing mechanism, then closes the sealing mechanism to prevent outside air from entering. The stirring mechanism is then activated to stir the epoxy resin, and the heating mechanism heats the epoxy resin to accelerate the expulsion of air bubbles. Simultaneously, the air extraction mechanism is activated to promptly extract air from the degassing kettle. After degassing is complete, the stirring mechanism is activated to squeeze and scrape away the epoxy resin, preventing blockages and residues within the device.

The sealing cover is rotatably mounted on the feeding cylinder, and the handle is mounted on the sealing cover. The operator pulls the handle to open the sealing cover, which facilitates the delivery of epoxy resin through the feeding cylinder into the cavity of the reactor body. Then, the sealing cover is closed to prevent outside air from entering.

After degassing is completed, the drive shaft drives the multiple sets of scrapers to rotate and scrape off the epoxy resin remaining on the inner wall of the cavity of the vessel. At the same time, it drives the spiral blades to rotate and squeeze the epoxy resin out, preventing the epoxy resin from clogging the discharge pipe.
