Description

Technical Field

[0001] The utility model belongs to the technical field of reaction kettles, in particular to a reaction kettle for preparing high-solid epoxy paint. Background Art

[0002] Epoxy paint is composed of epoxy resin, body pigment and curing agent. The paint containing more epoxy groups is collectively called epoxy paint. The main variety is two-component paint, which is composed of epoxy resin and curing agent. The main advantages of epoxy paint are strong adhesion to inorganic materials such as cement and metal; the paint itself is very corrosion-resistant; it has excellent mechanical properties, wear resistance and impact resistance; it can be made into solvent-free or high-solid paint; it is resistant to organic solvents, heat and water; the coating film is non-toxic, and is mainly used in floor coating, automotive primer, metal corrosion protection, chemical corrosion protection, etc. Among them, high-solid epoxy paint has the characteristics of high solid ratio and low viscosity. In the production and processing of high-solid epoxy paint, it is usually necessary to use a reactor to mix and process its various raw materials so that the various raw materials react under appropriate conditions to improve the processing efficiency of high-solid epoxy paint, but it still has the following disadvantages in actual use:

[0003] 1. The utility model with publication number CN217120235U discloses a dispersion reactor for producing high-solid oil-based coiled material topcoat, wherein an inlet medium channel and an outlet medium channel for heat transfer medium to pass through are provided inside the stirring shaft, the first mounting plate, the L-shaped connecting rod, the second mounting plate and the stirring blade. A sleeve is provided outside the propeller blade, and a second closed cavity connected to the first closed cavity is provided inside the side wall of the sleeve. A heat transfer pipe connected to the second closed cavity is provided outside the side wall of the sleeve. When the reactor processes the raw materials, it is often necessary to control the temperature of the reactor more accurately to ensure that the reaction temperature of the raw materials is within an appropriate range. However, a reactor often needs to be provided with a temperature control structure, and multiple reactors require multiple temperature control structures, which increases production expenses;

[0004] 2. When producing high-solid epoxy paint, a special stirring structure is often required to prevent the material from settling at the bottom of the reactor. However, the special stirring structure will cause many dead corners in the reactor body, making it difficult to clean and increasing the labor intensity of the staff. Utility Model Content

Through a heating tank and a reactor body, the problem that a stirring structure provided during production of the reactor to avoid material deposition has many dead corners during actual use and is difficult to clean, and multiple reactors require multiple temperature control structures for temperature regulation, thereby increasing production expenses is solved.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a reaction kettle for preparing high-solid epoxy paint, comprising a heating tank and a reaction kettle body, wherein a rotary motor is arranged at one end of the heating tank, a stirring motor is arranged at the other end of the heating tank, a plurality of reaction kettle bodies are clamped and fixed on the inner side of the heating tank, a top cover is clamped and fixed at one end of each reaction kettle body, and a stirring rod is clamped and connected through one side of each top cover;

The stirring motor can drive the multiple stirring rods to rotate, and the materials in the multiple reactor bodies can be stirred and processed, thereby reducing production costs.

[0014] The raw materials enter the inner side of the reactor body through the first feed pipe or the second feed pipe, and are discharged through the second feed pipe or the first feed pipe after processing. Multiple reactor bodies can process a variety of high-solid epoxy paint raw materials with certain ratio differences, and produce a variety of high-solid epoxy paints at the same time, thereby improving the flexibility of use.

[0015] Furthermore, a stirring blade is welded and fixed on the outer peripheral surface of each stirring rod, and the stirring blade is located inside the reactor body.

The heating tank can heat the multiple reactor bodies at the same time, and the fan of the heating tank can drive the flow of air to cool the multiple reactor bodies. The temperatures of the multiple reactor bodies can be regulated at the same time, thereby reducing production costs and expenses.

[0019] 2. The utility model solves the problem that a special stirring structure is often required to prevent materials from being deposited at the bottom of the reactor when preparing high-solid epoxy paint by arranging a heating tank and a reactor body. However, the special stirring structure will lead to many dead angles in the reactor body, making it difficult to clean and increasing the labor intensity of the staff. When the material is stirred, the heating tank is driven to rotate by a rotary motor, which further drives multiple reactor bodies to flip in the vertical direction, so that the deposited material moves in the reactor body under the action of gravity, ensuring uniform mixing of the materials and simplifying the structure in the reactor body for easy cleaning.
