Description

Technical Field

[0001] The utility model relates to the technical field of putty powder production, in particular to a coating raw material screening device. Background Art

[0002] Putty powder production refers to the process of mixing multiple raw materials (such as gypsum, lime, cement, clay and fiber, etc.) in a certain proportion and processing them into fine powdered building materials through a series of process steps (such as grinding, screening and mixing, etc.). In order to ensure the uniformity of putty powder product particles, corresponding screening equipment is needed to properly screen the putty powder raw materials.

[0003] According to the utility model with authorization announcement number CN217569540U, an environmentally friendly putty powder raw material screening device is disclosed. By setting up two layers of screening nets and quickly adjusting the mesh size, the required putty powder raw materials can be quickly and effectively screened out. At the same time, the device has a simple structure and is easy to operate.

[0004] Although this equipment can quickly and effectively screen out the required putty powder raw materials, the device always keeps the putty powder in an exposed state, and the humidity in the device environment is difficult to control due to the lack of a humidity regulation structure. Excessive humidity can easily clog the screen and affect the screening efficiency, while too low humidity can easily cause the putty powder particles to be too broken and affect its construction performance.

[0005] Therefore, a coating raw material screening device is needed to solve the above technical problems. Utility Model Content

[0015] Beneficial effects:

[0016] Compared with the existing technology, the coating raw material screening device has the following beneficial effects:

[0017] 1.

At the same time, the button controller controls the exhaust fan to energize to discharge the moisture in the screening box after filtering through the filter element. When the humidity in the screening box is smaller than the setting range of the button controller, the button controller can control the electric atomization head to energize to atomize the water stored in the water tank and spray it onto the putty powder and other coatings in the screening box until the humidity in the screening box reaches the humidity range set by the button controller again, thereby effectively adjusting the humidity in the screening box.

The inner wall of the coupling 16 is fixedly connected to the outer surface of the rotating rod 3. By providing the coupling 16, the connection between the output end of the servo motor 2 and the rotating rod 3 can be strengthened, thereby increasing the rotation stability of the rotating rod 3.

[0032] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 The inner wall of the screening box 1 is respectively fixedly connected with an electric heating ring plate 701, a water tank 706 and a temperature and humidity sensor 709. The inner wall of the screening box 1 is fixedly connected with an auxiliary bearing 17. The inner ring of the auxiliary bearing 17 is fixedly connected to the outer surface of the rotating rod 3. By providing the auxiliary bearing 17, the screening box 1 and the rotating rod 3 can be connected, thereby increasing the rotation smoothness of the rotating rod 3.

[0033] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a button controller 702 is fixedly connected to the upper surface of the screening box 1, a handle support 10 is fixedly connected to the front of the support frame 5, and a pull rod 11 is fixedly connected to the inner wall of the handle support 10. By providing the pull rod 11, a rotation base surface can be provided for the hand-gripping structure in the handle support 10, thereby increasing the flexibility of use of the hand-gripping structure. By providing the handle support 10 and the pull rod 11, the support frame 5 can be pulled together with the above-mentioned hand-gripping structure, thereby facilitating cleaning or replacing the screen 6 in the support frame 5;

[0034] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7 The inner wall of the water tank 706 is fixedly connected to the electric atomizer head 707, and a grip 12 is provided inside the handle support 10. The inner wall of the grip 12 is rotatably connected to the outer surface of the pull rod 11. By providing the grip 12, it can be rotated around the outer surface of the pull rod 11 inside the handle support 10, and then it is convenient to pull the support frame 5 after being grasped by the hand, thereby facilitating the cleaning or replacement of the screen 6 in the support frame 5;

[0035] See also Figure 1 、 Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 The inner wall of the exhaust tube 703 is fixedly connected with an exhaust fan 708, and the servo motor 2, the electric heating ring plate 701, the electric atomization head 707, the exhaust fan 708 and the temperature and humidity sensor 709 are all electrically connected to the button controller 702 through wires. The interior of the screening box 1 is clamped with a sealing plug 13, and the interior of the water tank 706 is clamped with a dust plug 14. The interior of the dust plug 14 is provided with several identical air cavities 15. By setting the sealing plug 13, the inside and outside of the screening box 1 can be effectively isolated to prevent external dry or humid air from entering the interior of the screening box 1 and interfering with the humidity environment inside the screening box 1. By setting the dust plug 14, external dust can be prevented from entering the interior of the water tank 706 and affecting the water quality inside the water tank 706. By setting the air cavity 15, the air pressure difference between the inside and outside of the water tank 706 can be effectively balanced, thereby preventing the dust plug 14 from being difficult to pull out after the water in the water tank 706 is completely atomized and consumed.

[0036] Working principle: First, remove the sealing plug 13 and put a sufficient amount of putty powder and other coatings to be screened into the screening box 1, then operate the button controller 702 to control the servo motor 2 to energize and drive the rotating rod 3 and the sweeping brush 4 to rotate, and then the sweeping brush 4 pushes the putty powder and other coatings in the screening box 1 to be stirred on the screen 6, and the putty powder and other coatings are screened by the screen 6, so that the putty powder and other coatings with appropriate particle size flow to the container pre-placed at the bottom of the screening box 1 for holding the screened putty powder and other coatings. During this period, the temperature and humidity sensor 709 monitors the ambient humidity in the screening box 1 at all times, and then when the humidity in the screening box 1 is larger than the setting range of the button controller 702, the button controller 702 controls the electric heating ring plate 701 to energize to heat the putty powder and other coatings in the screening box 1 and evaporate the moisture in the putty powder and other coatings, and at the same time press the button. The controller 702 controls the exhaust fan 708 to be powered on to discharge the moisture in the screening box 1 after filtering through the filter element 705. When the humidity in the screening box 1 is smaller than the setting range of the button controller 702, the button controller 702 controls the electric atomization head 707 to be powered on to atomize the water stored in the water tank 706 and spray it onto the putty powder and other coatings in the screening box 1 until the humidity in the screening box 1 reaches the humidity range set by the button controller 702 again. The button controller 702 can then stop powering each electrical component, thereby effectively regulating the humidity in the screening box 1. The design of the entire paint raw material screening device effectively solves the problem that due to the lack of a humidity regulating structure, excessive humidity can easily clog the screen 6 and affect the screening efficiency, and too low humidity can easily make the putty powder particles too broken and affect its construction performance.
