[0002] Fast-drying epoxy micaceous iron oxide intermediate paint plays an important role in industrial protective coating systems, and the uniformity of its raw material mixing directly affects product quality.
[0003] Several problems exist in the existing mixing process of epoxy micaceous iron oxide intermediate paint raw materials. Ordinary mixers have a simple mixing structure, often using an electric motor to drive the mixing blades to rotate, thereby mixing the materials in the mixing tank. While this method is simple in structure, it is difficult to quickly and thoroughly mix raw materials of different particle sizes and properties, resulting in long mixing times and low production efficiency. Furthermore, for some raw material components that are prone to sedimentation or have high viscosity, the mixing effect is poor, easily causing uneven mixing and affecting the performance stability of the intermediate paint. Therefore, it is necessary to design and modify a high-speed mixer for fast-drying epoxy micaceous iron oxide intermediate paint raw materials to effectively prevent the problems of low mixing efficiency and poor mixing effect. Utility Model Content

The output end of the second motor is fixedly connected to the sprocket. A second electromagnetic discharge valve is connected to the bottom of the first mixing drum.
[0006] The beneficial effects of this utility model are as follows:
[0007] 1. This utility model adopts a unique double-layer mixing design. The upper second mixing drum is equipped with a first mixing rod driven by a first motor, which can pre-mix the materials poured in. The lower first mixing drum is equipped with three spiral conveying rods evenly distributed in a ring, driven by a second motor through sprockets and chains to convey the materials upwards, achieving efficient mixing. At the same time, a third motor drives the second mixing rod and the connected cleaning frame and round rod to rotate back and forth in the first mixing drum, which can not only further mix the materials, but also clean the materials accumulated on the drum wall.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] like Figures 1 to 6 As shown, the high-speed mixer for quick-drying epoxy micaceous iron oxide intermediate paint raw materials in this embodiment includes a base plate 1. Four support columns 2 are fixedly connected to the top of the base plate 1. A support plate 3 is fixedly connected to the top of each support column 2. A first mixing drum 4 is fixedly connected inside the support plate 3. A second mixing drum 5 is positioned above the first mixing drum 4. A first electromagnetic discharge valve 6 is connected to both the front and rear sides of the bottom of the second mixing drum 5. A discharge pipe 7 is connected to the bottom of the first electromagnetic discharge valve 6. A first stirring rod 8 is rotatably connected inside the second mixing drum 5. A first motor is fixedly connected to the bottom of the second mixing drum 5, and the output end of the first motor is fixedly connected to the first stirring rod 8. A spiral conveyor rod 9 is rotatably connected inside the first mixing drum 4. There are three spiral conveying rods 9, which are evenly distributed in a ring inside the first mixing drum 4. A support plate 10 is fixedly connected inside the first mixing drum 4. There are several support plates 10, which are evenly distributed in a ring inside the first mixing drum 4. The support plates 10 are rotatably connected to the spiral conveying rods 9. The bottom of the spiral conveying rods 9 extends to the bottom of the first mixing drum 4 and is fixedly connected to a sprocket 11. The sprockets 11 are connected to each other by chain drive. A fixed frame is fixedly connected to the bottom of the first mixing drum 4. A second motor 12 is fixedly connected to the surface of the fixed frame. The output end of the second motor 12 is fixedly connected to the sprocket 11. A second electromagnetic discharge valve 13 is connected to the bottom of the first mixing drum 4.
[0017] refer to Figure 3 A support frame is fixedly connected to the top of the support plate 3, and a third motor is fixedly connected to the top of the support frame. A second stirring rod 15 is rotatably connected inside the support frame, and the output end of the third motor is fixedly connected to the second stirring rod 15.
[0018] In this embodiment, the support frame, the third motor, and the second stirring rod 15 are arranged so that the rotation of the third motor drives the rotation of the second stirring rod 15, thereby stirring the material in the first stirring drum 4, thus improving the stirring efficiency and stirring effect of the device.
[0019] refer to Figure 3 A cleaning rack 16 is fixedly connected to the bottom of the second stirring rod 15. The cleaning rack 16 is attached to the inner wall of the first stirring drum 4. A round rod 17 is fixedly connected to the surface of the cleaning rack 16. There are several round rods 17, which are evenly distributed on the surface of the cleaning rack 16.
[0020] In this embodiment, the cleaning frame 16 and the round rod 17 are arranged so that the rotation of the second stirring rod 15 drives the cleaning frame 16 to rotate. The cleaning frame 16 is in contact with the inner wall of the first stirring drum 4. The cleaning frame 16 can clean and scrape off the material accumulated on the inner wall of the first stirring drum 4. When the cleaning frame 16 rotates, it will drive the round rod 17 to rotate, thereby assisting in the stirring of the material and improving the stirring efficiency and effect. In order to avoid the cleaning frame 16 from hitting the spiral conveyor rod 9, the third motor is reciprocating, thereby driving the second stirring rod 15 and the cleaning frame 16 to rotate reciprocally, thus preventing the cleaning frame 16 from hitting the spiral conveyor rod 9 when rotating.
[0021] refer to Figure 4 A support frame 18 is fixedly connected to the top of the support plate 3. There are four support frames 18, which are evenly distributed on the top of the support plate 3. A movable frame 19 is slidably connected inside the support frame 18. The top of the movable frame 19 extends above the support frame 18 and is fixedly connected to a movable plate 20. An electric cylinder 21 is fixedly connected to the bottom of the inner wall of the support frame 18. The output end of the electric cylinder 21 is fixedly connected to the movable frame 19. The movable plate 20 is fixedly connected to the second stirring drum 5.
[0022] In this embodiment, the support frame 18, the movable frame 19, and the electric cylinder 21 are arranged so that the electric cylinder 21 extends and drives the movable frame 19 to move upward, thereby driving the movable plate 20 and the second stirring drum 5 to move upward, thus increasing the distance between the first stirring drum 4 and the second stirring drum 5. This makes it easier for the operator to clean or maintain the components inside the first stirring drum 4. The movable frame 19 cooperates with the support frame 18 and slides stably up and down inside the support frame 18, thereby ensuring that the movable plate 20 and the second stirring drum 5 slide stably up and down.
[0023] refer to Figure 1 A collection box 14 is provided on the top of the base plate 1. A handle is fixedly connected to the front of the collection box 14. The surface of the handle is provided with anti-slip texture, and there are several anti-slip textures, which are evenly distributed on the surface of the handle. The bottom of the collection box 14 is smooth.
[0024] In this embodiment, the collection box 14 is provided so that the stirred material can be collected. The operator can hold the handle and pull the collection box 14 out in front. The anti-slip texture is not shown.
[0025] refer to Figure 2 Bearings are fixedly connected inside the first mixing drum 4 and the second mixing drum 5, respectively. The outer ring of the bearing is fixedly connected to the first mixing drum 4 and the second mixing drum 5, respectively. The inner ring of the bearing is fixedly connected to the screw conveyor rod 9 and the first mixing rod 8, respectively. Lubricating oil is provided inside the bearing, and a sealing shaft cover is provided inside the bearing.
[0026] In this embodiment, the friction between the first stirring drum 4 and the spiral conveying rod 9 and the friction between the second stirring drum 5 and the first stirring rod 8 can be reduced by the bearing, thereby facilitating the rotation of the spiral conveying rod 9 and the first stirring rod 8. The bearing and the sealing shaft cover mentioned above are common existing technologies and are common knowledge to those skilled in the art. They will not be described in detail in this application. The bearing is not shown.
[0027] The material is poured into the second mixing drum 5, and then the first motor is started to rotate, driving the first mixing rod 8 to rotate, thereby pre-mixing the material in the second mixing drum 5. After the pre-mixing is completed, the first electromagnetic discharge valve 6 is started, so that the material in the second mixing drum 5 falls into the first mixing drum 4 through the discharge pipe 7. Then the second motor 12 is started to rotate, driving the sprocket 11 to rotate. Under the action of the chain, each sprocket 11 and the screw conveyor 9 rotate. The screw conveyor 9 can convey the material upward, thereby mixing the material in the first mixing drum 4. The third motor reciprocates to drive the second mixing rod 15, the cleaning frame 16 and the round rod 17 to reciprocate to further mix the material in the first mixing drum 4, thereby improving the mixing efficiency and mixing effect of the device. After the mixing is completed, the operator starts the second electromagnetic discharge valve 13, so that the material in the first mixing drum 4 falls into the collection box 14.
[0028] The synchronization controller can coordinate the movement of multiple electric cylinders 21, ensuring that they operate at the same speed and displacement. By connecting multiple electric cylinders 21 to the synchronization controller and setting parameters such as movement speed and stroke through the controller, the controller will issue unified commands to drive each electric cylinder 21 to operate synchronously, thereby enabling the movable frame 19, the movable plate 20, and the second stirring drum 5 to move up and down smoothly. The aforementioned synchronization controller is a common existing technology and will not be described in detail in this application.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
