Description

Technical Field

[0001] This utility model relates to the technical field of preparing reaction vessels, and in particular to a primer preparation reaction vessel. Background Technology

[0002] As a core material in the coatings industry, primer's performance directly affects the adhesion, corrosion resistance, and service life of the coating. During primer preparation, traditional single-layer stirring blades struggle to handle high-viscosity materials, leading to uneven mixing and a wide molecular weight distribution of reaction products, thus impacting processing quality.

[0003] For example, the existing technology announcement number CN214810819U discloses a reaction vessel for preparing epoxy coatings, including a reaction vessel body, a support base fixedly installed at the lower end of the reaction vessel body, and a sealing cover installed at the upper end of the reaction vessel body.

[0004] During the use of existing equipment, it was found that the existing equipment has poor mixing uniformity in the preparation of primer and low mixing efficiency, which reduces the preparation reaction effect. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a primer preparation reactor that improves the uniformity of primer processing, increases processing efficiency, and enhances the convenience of reaction temperature control.

[0006] This utility model discloses a primer preparation reaction vessel, including a tank body and a feed valve; The feed valve is connected to the top of the tank; it also includes a drive unit, a mixing unit, a heating unit, a discharge valve, a bracket, and a support shaft; The discharge valve is connected to the bottom of the tank. The support shafts are located on both sides of the tank and are rotatably mounted on the bracket; The drive unit is located between the bracket and the support shaft, and is used to drive the rotation of the support shaft; The mixing device is located inside the tank and is used to mix and react the primer. The heating device is installed inside the tank and is used to heat the primer for reaction. The primer to be prepared is put into the tank through the feed valve. Then, the mixing device is started to mix the primer in the tank for reaction processing. At the same time, the drive device drives the support shaft to rotate, and the rotation of the support shaft causes the tank to tumble, thereby circulating the primer in the tank. The tumbling of the tank and the use of the mixing device improve the uniformity of primer processing and increase processing efficiency. The heating device heats and keeps the temperature inside the tank constant, improving the convenience of reaction temperature control.

[0007] Preferably, the mixing device includes a sleeve, a rotating shaft, a first stirring blade, a second stirring blade, a first bevel gear, a first motor, and a second bevel gear; The sleeve is rotatably installed in the upper part of the tank body; The upper part of the rotating shaft rotates through the inside of the sleeve, and the bottom end of the rotating shaft is rotated and installed on the inner side wall of the tank. The upper part of the first stirring blade is mounted on the outer wall of the sleeve, and the lower part of the first stirring blade is rotated and sleeved on the outer wall of the rotating shaft. Multiple sets of second stirring blades are respectively installed on the outer wall of the sleeve and the rotating shaft; The two sets of first bevel gears are respectively installed on the upper part of the outer side wall of the sleeve and the rotating shaft; The first motor is installed on the outer wall of the tank. The second bevel gear is rotatably mounted on the outer wall of the tank and meshes with two sets of first bevel gears. The output end of the first motor is connected to the second bevel gear. The first motor drives the second bevel gear to rotate. After the second bevel gear rotates, it meshes with the two sets of first bevel gears and drives the sleeve to rotate clockwise and the shaft to rotate counterclockwise, respectively. This causes the second stirring blade on the sleeve and the second stirring blade on the shaft to rotate and stir in opposite directions, improving the mixing and shearing effect of the primer, improving the mixing uniformity, improving the mixing efficiency, and improving the quality of the preparation reaction.

[0008] Preferably, the drive device includes a braking device, a first spur gear, a second spur gear, and a second motor; The first spur gear is mounted on the left support shaft; The second spur gear is rotatably mounted on the bracket and meshes with the first spur gear, and the diameter of the first spur gear is larger than the diameter of the second spur gear; The second motor is mounted on the outer wall of the bracket and connected to the second spur gear; The braking device is installed on the right support shaft and is used to brake the rotation of the support shaft. The second motor drives the second spur gear to rotate, and the second spur gear drives the tank to rotate through meshing with the first spur gear. Due to the diameter difference between the first spur gear and the second spur gear, a speed reduction structure is formed, which increases the torque of the second motor and improves the rotational stability of the tank. After the primer reaction in the tank is completed, the braking device brakes the support shaft, thereby improving the angle fixation effect of the tank.

[0009] Preferably, the braking device includes a friction ring, a brake pad, and a telescopic rod; The friction ring is located on the outer wall of the right support shaft; Brake pads are installed on the moving end of the telescopic rod and the cylinder; Both the telescopic rod and the cylinder are installed on the outer wall of the bracket; the cylinder drives the brake pad to move, so that the brake pad contacts the friction ring, thereby slowing down the rotation of the friction ring and improving the convenience of rotating braking and positioning of the tank.

[0010] Preferably, the heating device includes a heat-conducting inner liner and an electric heating element; The heat-conducting inner liner is installed on the inner side wall of the tank. The heating element is installed inside the heat-conducting inner liner; the heating element heats the heat-conducting inner liner, which in turn heats the primer inside the tank through heat conduction, thereby improving the heating and temperature control effect of primer preparation.

[0011] Preferably, an electromagnetic slip ring is provided between the bracket and the support shaft; when the support shaft rotates, the electromagnetic slip ring supplies power to the first motor and the heating element, improving processing convenience.

[0012] Preferably, the bottom of the tank is provided with a guide slope; this improves the convenience of the primer being discharged from the tank through the discharge valve and reduces primer residue in the tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the primer to be prepared is put into the tank through the feed valve, and then the mixing device is started to mix and prepare the primer in the tank for reaction processing. At the same time, the drive device drives the support shaft to rotate, and the rotation of the support shaft drives the tank to tumble, thereby circulating the primer in the tank. The tumbling of the tank and the use of the mixing device improve the uniformity of primer preparation and improve the processing efficiency. The heating device heats and keeps the temperature in the tank constant, improving the convenience of reaction temperature control. Attached Figure Description
