Description

Technical Field

[0001] This utility model belongs to the technical field of storage equipment for ultra-weather-resistant and environmentally friendly polyester powder coatings, and particularly relates to an anti-caking storage device for ultra-weather-resistant and environmentally friendly polyester powder coatings. Background Technology

[0002] Ultra-weather-resistant and environmentally friendly polyester powder coating is a powder coating made with polyester resin as the main film-forming substance, and adding weather-resistant additives (such as UV absorbers and weather-resistant fillers) and environmentally friendly curing agents. After electrostatic spraying and high-temperature curing, it can form a coating with excellent weather resistance and environmental protection characteristics on the surface of the workpiece. Its molecular structure design enhances the resin's resistance to photoaging, and the combination with nano-level weather-resistant fillers improves the coating's resistance to ultraviolet rays, rainwater erosion, and temperature differences. Furthermore, there are no volatile organic compound (VOC) emissions during production and construction, meeting environmental standards. The cured coating has a long weather life (10-15 years of outdoor use without discoloration or chalking), strong adhesion, and resistance to chemical corrosion.

[0003] Because ultra-weather-resistant and environmentally friendly polyester powder coatings are prone to clumping when exposed to water, using a vacuum environment to reduce the moisture content of the storage environment for ultra-weather-resistant and environmentally friendly polyester powder coatings is costly. Inexpensive vacuum containers have high leakage rates and short vacuum maintenance times. Placing desiccants inside the containers can also alleviate the problem of excessive moisture, but since the humid gas is already dispersed between the gaps in the ultra-weather-resistant and environmentally friendly polyester powder coatings at the beginning of storage, and the internal air circulation is poor, the desiccant only comes into contact with a very limited amount of gas. Before the desiccant can take effect, clumping still occurs inside, resulting in the low practicality of conventional ultra-weather-resistant and environmentally friendly polyester powder coating storage equipment.

[0004] To address this issue, we propose an anti-caking storage device for ultra-weather-resistant and environmentally friendly polyester powder coatings. Utility Model Content

[0005] The purpose of this invention is to address the problem of low practicality of conventional ultra-weather-resistant and environmentally friendly polyester powder coating storage equipment, and to propose an anti-caking storage device for ultra-weather-resistant and environmentally friendly polyester powder coating.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A storage device for preventing caking of ultra-weather-resistant and environmentally friendly polyester powder coating includes an extraction nozzle. A sealing cap is fixedly connected to the lower end of the extraction nozzle. A desiccant storage box is threaded into the inner thread of the sealing cap, and a storage tank is threaded into the lower thread of the sealing cap. The desiccant storage box is unscrewed, a desiccant packet is placed inside, the desiccant storage box is screwed into the sealing cap, and the sealing cap is tightened onto the storage tank. An extraction device is used to extract gas from the storage tank through the extraction nozzle, reducing the gas density and thus the overall moisture content. Taking advantage of the non-absolute seal of the extraction nozzle, gas is slowly introduced into the desiccant storage box and then slowly enters the storage tank. The slow gas flow allows the desiccant to fully absorb moisture from the gas within the storage box, ensuring the dryness of the gas entering the storage tank and reducing the caking rate of the ultra-weather-resistant and environmentally friendly polyester powder coating.

[0008] Preferably, the storage tank includes a tank body, and a first threaded ring is fixedly connected to the upper end of the tank body. The tank body and the first threaded ring are an integral structure.

[0009] Preferably, the sealing cap includes a cap body with a hollowed-out air hole in the center. A second threaded ring is fixedly connected to the lower part of the cap body. The cap body is threadedly sealed onto the first threaded ring, and an air extraction nozzle is fixedly connected to the upper end of the cap body. The internal space of the air extraction nozzle communicates with the internal space of the air hole. Utilizing the air leakage disadvantage of the air extraction nozzle, gas is slowly allowed to enter the desiccant storage box through the air hole, facilitating the desiccant in the storage box to fully absorb the moisture in the gas.

[0010] Preferably, the outer periphery of the cover is provided with anti-slip texture.

[0011] Preferably, the desiccant storage box includes a box body, and a retaining ring is provided inside the box body. The lower end of the retaining ring is fixedly connected to the box body, and a ventilation opening is provided at the lower end of the box body. The retaining ring is movably inserted into a second threaded ring, and the box body is threaded onto the outside of the second threaded ring. When the desiccant packet is placed inside the retaining ring, and the box body is screwed onto the second threaded ring, gas leaking into the storage tank through the vent will diffuse outward through the center of the desiccant inside the retaining ring and into the ventilation opening, thus discharging into the tank. This gas flow from the center outward ensures uniform contact between the gas and the desiccant.

[0012] Preferably, the outer periphery of the box body is provided with anti-slip vertical grooves.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. Unscrew the desiccant storage box, then place the desiccant packet inside. Screw the desiccant storage box into the sealing cap, and tighten the sealing cap onto the storage tank. Use an air extraction device to extract the gas from the storage tank through the air extraction nozzle, reducing the gas density inside the storage tank and thus reducing the overall moisture content. Taking advantage of the non-absolute seal of the air extraction nozzle, the gas is slowly introduced into the desiccant storage box through the nozzle and then slowly enters the storage tank. Utilizing the slow gas flow, the gas is fully absorbed by the desiccant within the storage box, ensuring the dryness of the gas entering the storage tank and thus reducing the clumping rate of the ultra-weather-resistant environmentally friendly polyester powder coating inside the storage tank.

[0015] 2. Taking advantage of the leakage of the air extraction nozzle, the gas is allowed to slowly enter the desiccant storage box through the air hole, which facilitates the desiccant in the storage box to fully absorb the moisture in the gas.

[0016] 3. Place the desiccant pack inside the retaining ring, screw the box onto the second threaded ring, and the gas leaking into the storage tank through the vent will diffuse outward through the center of the desiccant inside the retaining ring and into the vent, thus being discharged into the tank. The gas will be evenly contacted with the desiccant by the flow of gas from the center to the periphery. Attached Figure Description

[0022] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0023] like Figure 1As shown, an anti-caking storage device for ultra-weather-resistant and environmentally friendly polyester powder coating includes an air extraction nozzle 1, a sealing cap 3 fixedly connected to the lower end of the air extraction nozzle 1, a desiccant storage box 4 installed in the internal thread of the sealing cap 3, and a storage tank 2 sealed in the lower thread of the sealing cap 3.

[0024] like Figure 1 and 2 As shown, the storage tank 2 includes a tank body 21, and a first threaded ring 22 is fixedly connected to the upper end of the tank body 21. The tank body 21 and the first threaded ring 22 are an integral structure. The first threaded ring 22 is used to thread-seal the sealing cap 3.

[0025] like Figure 1 and 3 As shown, the sealing cap 3 includes a cap body 31, with an air hole 33 hollowed out in the middle of the cap body 31. A second threaded ring 32 is fixedly connected to the lower part of the cap body 31. The cap body 31 is threadedly sealed onto the first threaded ring 22. An air extraction nozzle 1 is fixedly connected to the upper end of the cap body 31, and the internal space of the air extraction nozzle 1 communicates with the internal space of the air hole 33. Taking advantage of the air leakage defect of the air extraction nozzle 1, gas is slowly allowed to enter the desiccant storage box 4 through the air hole 33.

[0026] like Figure 3 As shown, the outer periphery of the cover 31 is provided with anti-slip texture. The anti-slip texture increases the friction between the hand and the cover 31.

[0027] like Figure 1 and 4 As shown, the desiccant storage box 4 includes a box body 42, with a retaining ring 41 inside the box body 42. The lower end of the retaining ring 41 is fixedly connected to the box body 42, and a vent 43 is cut out at the lower end of the box body 42. The retaining ring 41 is movably inserted into a second threaded ring 32, and the box body 42 is threaded onto the outside of the second threaded ring 32. When the desiccant pack is placed inside the retaining ring 41, the box body 42 is screwed onto the second threaded ring 32. Gas leaking into the storage tank 2 through the vent 33 diffuses outward through the center of the desiccant inside the retaining ring 41 into the vent 43 and is discharged into the tank 21. The gas is evenly contacted with the desiccant by the flow of gas from the center to the periphery.

[0028] like Figure 4 As shown, anti-slip vertical grooves are formed on the outer perimeter of the box 42. These grooves increase the friction between the box 42 and the hand.

[0029] Working principle: Unscrew the desiccant storage box 4, then place the desiccant pack into the desiccant storage box 4, screw the desiccant storage box 4 into the sealing cap 3, and tighten the sealing cap 3 onto the storage tank 2. Use an air extraction device to extract the gas from the storage tank 2 through the air extraction nozzle 1, reducing the gas density in the storage tank 2 and thus reducing the overall moisture content in the storage tank 2. Taking advantage of the fact that the air extraction nozzle 1 is not absolutely sealed, the gas is slowly introduced into the desiccant storage box 4 through the air extraction nozzle 1 and slowly enters the storage tank 2 through the desiccant storage box 4. Utilizing the slow gas flow, the gas is fully absorbed by the desiccant in the desiccant storage box 4, ensuring the dryness of the gas entering the storage tank 2.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed by the utility model, based on the technical solution and the utility model concept, should be included within the protection scope of the utility model.

[0031] The description briefly mentions the application direction of the utility model in relation to existing technologies known to those skilled in the art without modification, and combines them with the utility model to form a complete technology; it avoids excessive popularization of technologies known to those skilled in the art, in order to help those skilled in the art quickly understand the main content of the utility model.
