Description

Technical Field

[0001] The utility model relates to the technical field of modified epoxy resin production, in particular to a heat preservation device used for modified epoxy resin production. Background Art

[0002] Epoxy resin is a high molecular polymer, which refers to a general term for a class of polymers containing two or more epoxy groups in the molecule. It is a condensation product of epichlorohydrin and bisphenol A or polyols. Due to the chemical activity of the epoxy group, it can be opened with a variety of compounds containing active hydrogen, cured and cross-linked to form a network structure. It is a thermosetting resin. Modified epoxy resin is a two-component, low-VOC, thick paste type, modified epoxy shielding coating. When producing modified epoxy resin, it is necessary to use an insulation device for insulation. However, most of the insulation devices used for modified epoxy resin production in the prior art still have problems that need to be solved during use.

[0003] In the prior art, most of the insulation devices used for the production of modified epoxy resins have a stirring rod inside the insulation device to ensure that the epoxy resin can be evenly heated. The epoxy resin is stirred by the stirring rod. However, the rotation of the stirring rod will cause the epoxy resin to move along the moving path of the stirring blade, resulting in a slower dispersion of the epoxy resin, which causes the epoxy resin to be unable to be evenly heated, resulting in different heating effects, and affecting the product quality of the epoxy resin. Therefore, it is necessary to design an insulation device for the production of modified epoxy resin to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a heat preservation device for the production of modified epoxy resin.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The cam is an axially axially axially axially axially axially axially connected to the gear train of the motor, and the cam is connected to the gear train of the motor through the cam, and the cam is connected to the gear train of the motor through the cam. The I-wheel sleeve is provided with a fixing plate, the fixing plate is fixedly connected to the inner wall of the installation box, the I-wheel is fixedly connected to a first stirring rod on the side away from the gear, the first stirring rod passes through the installation box, and a plurality of second stirring rods are fixedly connected to the outer wall of the first stirring rod. Since a technical means is adopted that the second stirring rod can be rotated while the first stirring rod is rotated, when the epoxy resin moves along the moving path of the stirring blade, the second stirring rod can stir the epoxy resin so that the epoxy resin can be quickly dispersed, which effectively solves the problem that the stirring effect of most of the insulation devices used for the production of modified epoxy resin in the prior art mentioned in the background technology is not ideal, which will cause the epoxy resin to disperse slowly, resulting in the epoxy resin not being able to be heated evenly, and the heating effect is different, affecting the product quality of the epoxy resin, thereby achieving the technical effect of ensuring that the epoxy resin can be heated evenly, improving the insulation effect, and ensuring the product quality of the epoxy resin.

[0007] As a further solution of the present invention, a heating wire is arranged inside the heating tube.

[0008] As a further solution of the utility model, the bottom of the fixed plate located at the bottom is rotatably connected to a second set of plates, the outer wall of the second set of plates is provided with a first air pipe, the first air pipe is provided with an air pump on the side away from the second set of plates, the air outlet of the air pump is connected to the first air pipe, the air inlet of the air pump is connected to the second air pipe, the second air pipe passes through the insulation box and the inner cylinder, and a second pressure relief valve is provided on the top of the fixed plate located at the top.

[0009] As a further solution of the utility model, a first pressure relief valve is fixedly connected to the outer wall of the bottom end of the insulation box, the top ends of the insulation box and the inner tube are both provided with the same feed pipe, and the bottom ends of the insulation box and the inner tube are both provided with the same discharge pipe.

[0010] As a further solution of the utility model, a box cover is arranged on the top of the heat preservation box, and the outer wall of the bottom end of the heat preservation box is fixedly connected with supporting feet.

[0011] As a further solution of the utility model, a plurality of air holes are provided at the top end of the inner tube.

[0012] The beneficial effects of the utility model are:

[0013] The utility model adopts a technical means that the second stirring rod can be rotated while the first stirring rod is rotating. Therefore, when the epoxy resin moves along the moving path of the stirring blade, the second stirring rod can stir the epoxy resin so that the epoxy resin can be quickly dispersed, which effectively solves the problem that most of the existing insulation devices used for modified epoxy resin production in the background technology have unsatisfactory stirring effects, which will cause the epoxy resin to disperse slowly, resulting in the epoxy resin being unable to be heated evenly, the heating effect being different, and affecting the product quality of the epoxy resin. Therefore, the technical effect of ensuring that the epoxy resin can be heated evenly, improving the insulation effect, and ensuring the product quality of the epoxy resin is achieved.
