Description

Technical Field

[0001] This application relates to the technical field of storage of pure polyester weather-resistant powder coatings, and in particular to a drying and storage device for pure polyester weather-resistant powder coatings. Background Technology

[0002] Pure polyester powder coatings are thermosetting powder coatings made with hydroxyl polyester resin as the main film-forming substance, combined with curing agents, pigments, fillers, and additives. This type of coating exhibits excellent weather resistance, decorative properties, and film fullness, and is not prone to yellowing during baking. It is widely used in building materials, home appliances, and general industrial fields. In recent years, its application in door and window profiles, transportation facilities, automotive parts, and outdoor furniture has continued to expand. Under standard storage conditions, the product can be stably stored for 12 months; even after this period, it can still be used after passing inspection.

[0003] The current storage method is to directly place pure polyester powder coatings in a storage tank and seal them. However, when pure polyester powder coatings are piled up, the heat inside the coating will accumulate and generate hot air. The hot air is difficult to dissipate, which will affect the stability of the pure polyester powder coating.

[0004] Therefore, it is urgent to improve existing storage equipment in order to enhance the storage performance of pure polyester powder coatings. Utility Model Content

[0005] The purpose of this application is to provide a drying and storage device for pure polyester weather-resistant powder coatings to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a drying and storage device for pure polyester weather-resistant powder coatings, employing the following technical solution: A drying and storage device for pure polyester weather-resistant powder coating includes a storage tank, a power support frame, and a central drying assembly. The storage tank is horizontally rotatably connected to the power support frame. Both ends of the storage tank are open. One side of the storage tank has a funnel-shaped discharge hopper, on which a butterfly valve and multiple waterproof and breathable valves are installed. The central drying assembly passes through the storage tank and is rotatably connected to it. The central drying assembly includes a central heating pipe, a sealing bearing, a heat insulation ring, and baffles. Both ends of the central heating pipe pass through the storage tank. Heat insulation rings are symmetrically fixed on the surface of the central heating pipe. The sealing bearing is sleeved on the outer ring of the heat insulation ring and installed in the end opening of the storage tank. Baffles are symmetrically and obliquely fixed on both sides of the central heating pipe. Multiple strip-shaped protrusions are also provided on the inner wall of the storage tank.

[0007] The power support frame has symmetrical support rollers on both sides of its surface. The storage tank is rotatably mounted on the support rollers. An external gear ring is installed on one side of the storage tank. A reduction motor is also fixed on the power support frame. A gear is installed at the output end of the reduction motor, and the gear meshes with the external gear ring.

[0008] The central heating pipe is located inside the storage tank, and the pipe body is the heating section, where an electric heater is installed.

[0009] The two ends of the central heating tube are fixed to the power support frame.

[0010] There is a gap between the strip-shaped protrusion and the baffle.

[0011] Preferably, multiple tie rods are evenly fixed between the baffle and the central heating tube.

[0012] By adopting the above technical solution, the setting of the tie rod can, on the one hand, improve the strength of the baffle and prevent it from being squeezed and deformed by the pure polyester weather-resistant powder coating. On the other hand, the tie rod can also transfer the heat of the central heating pipe to the baffle, so as to improve the heat transfer effect between the pure polyester weather-resistant powder coating and the baffle.

[0013] The storage tank is also equipped with a rechargeable humidity sensor and a rechargeable temperature sensor.

[0014] In summary, this application includes at least one of the following beneficial technical effects: the storage tank and the central drying component in the pure polyester weather-resistant powder coating drying and storage device can rotate relative to each other. The storage tank is lifted to a high position by strip-shaped protrusions and then dropped, repeating this process to agitate the pure polyester weather-resistant powder coating inside the storage tank. This allows the heat accumulated in the middle of the storage tank to dissipate quickly, and the hot air is discharged through the waterproof vent valve, preventing the temperature in the middle of the storage tank from becoming too high. When the humidity inside the storage tank is high, the electric heater inside the central drying component can be activated to dry the pure polyester weather-resistant powder coating. This device is fully functional, greatly improving the storage effect of the pure polyester weather-resistant powder coating and ensuring its storage stability. Attached Figure Description

Detailed Implementation

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a drying and storage device for pure polyester weather-resistant powder coating, referring to... Figure 1-3 The system includes a storage tank 1, a power support frame 2, and a central drying assembly. The storage tank 1 is horizontally rotatably connected to the power support frame 2. Both ends of the storage tank 1 are open. One side of the storage tank 1 has a funnel-shaped discharge hopper 11, on which a butterfly valve 12 and multiple waterproof and breathable valves 13 are installed. The central drying assembly penetrates the storage tank 1, and the storage tank 1 and the central drying assembly are rotatably connected. The central drying assembly includes a central heating pipe 3, a sealed bearing 4, a heat insulation ring 5, and a baffle 6. The heating tube 3 is installed through the storage tank 1 at both ends. The middle heating tube 3 is located inside the storage tank 1 and is the heating section 31. An electric heater is installed in the heating section 31. A heat insulation ring 5 is symmetrically fixed on the surface of the middle heating tube 3. A sealing bearing 4 is sleeved on the outer ring of the heat insulation ring 5. The outer ring of the sealing bearing 4 is installed in the end opening of the storage tank 1. Baffles 6 are symmetrically and obliquely fixed on both sides of the middle heating tube 3. Multiple strip-shaped protrusions 14 are also provided on the inner wall of the storage tank 1. There is a gap between the strip-shaped protrusions 14 and the baffles 6.

[0021] Support rollers 21 are symmetrically arranged on both sides of the surface of the power support frame 2. The storage tank 1 is rotatably mounted on the support rollers 21. An external gear ring 22 is installed on one side of the surface of the storage tank 1. A reduction motor 23 is also fixed on the power support frame 2. A gear is installed at the output end of the reduction motor 23. The gear meshes with the external gear ring 22. The two ends of the central heating pipe 3 are fixed on the power support frame 2.

[0022] The storage tank 1 is also equipped with a rechargeable humidity sensor and a rechargeable temperature sensor.

[0023] Reference Figure 2 Multiple reinforcing ribs 7 are evenly fixed between the baffle 6 and the central heating pipe 3. By setting the reinforcing ribs 7, the strength of the baffle 6 can be improved to prevent it from being squeezed and deformed by the pure polyester weather-resistant powder coating. On the other hand, the reinforcing ribs 7 can also transfer the heat of the central heating pipe 3 to the baffle 6, so as to improve the heat transfer effect between the pure polyester weather-resistant powder coating and the baffle 6.

[0024] The implementation principle of the drying and storage device for pure polyester weather-resistant powder coating in this application is as follows: When the rechargeable temperature sensor detects an increase in temperature inside storage tank 1, the geared motor 23 drives storage tank 1 to rotate via gears and external gear ring 22. Storage tank 1 lifts the pure polyester weather-resistant powder coating to a high place and drops it through the strip-shaped protrusion 14. This process is repeated to agitate the pure polyester weather-resistant powder coating inside storage tank 1, allowing the heat accumulated in the middle of storage tank 1 to dissipate quickly. The hot air is discharged through the waterproof vent valve 13, preventing the temperature in the middle of storage tank 1 from becoming too high.

[0025] When the rechargeable humidity sensor detects an increase in humidity, the geared motor 23 drives the storage tank 1 to rotate via gears and an external gear ring 22. The storage tank 1 lifts the pure polyester weather-resistant powder coating to a high place and drops it through the strip-shaped protrusion 14. This process is repeated to agitate the pure polyester weather-resistant powder coating inside the storage tank 1. During this process, the electric heater works to transfer heat to the heating section 31. The pure polyester weather-resistant powder coating exchanges heat with the heating section 31 and the baffle 6, which evaporates the moisture in the pure polyester weather-resistant powder coating and keeps it dry. After drying is completed, the geared motor 23 continues to work, continuously agitating the pure polyester weather-resistant powder coating to allow it to cool down naturally.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
