Description

Technical Field

[0001] This utility model relates to the field of storage equipment technology, specifically a powder coating storage device. Background Technology

[0002] Powder coatings are solid powdered synthetic resin coatings composed of solid resin, pigments, fillers, and additives. They are broadly classified into thermoplastic and thermosetting types. Powder coatings require storage during the production process. Prolonged storage in storage tanks can lead to clumping due to the attraction between powder particles and moisture absorption, affecting the performance of the powder coating.

[0003] To avoid clumping during powder coating storage, existing technologies such as the Chinese utility model patent "A Powder Coating Storage Bucket for Preventing Clumping" (application number CN202321158328.7), the Chinese utility model patent "A Powder Coating Storage Bucket" (application number CNCN201620539868.3), and the Chinese utility model patent "A Powder Coating Storage Device" (application number CN202421669056.1) all use motor-driven stirring blades to stir and disperse the powder coating, thus preventing it from clumping when left to stand.

[0004] Although the existing powder coating storage equipment can stir the powder coating and prevent it from clumping when left to stand, it has the following problems: powder coatings are generally prone to absorbing moisture and becoming damp. Simply stirring and breaking up the powder coating without heating it makes it difficult to effectively remove the moisture from the powder coating, which reduces the storage quality of the powder coating. Its structure needs to be improved. Utility Model Content

[0005] To address the problem that existing powder coating storage equipment only stirs and disperses the powder coating without heating, making it difficult to effectively remove moisture and thus reducing the storage quality of the powder coating, this utility model provides a powder coating storage device, the specific technical solution of which is as follows:

[0006] A powder coating storage device includes a tank, a stirring motor, a stirring shaft, stirring blades, and a heating element. The tank is used to store powder coating. The stirring motor is fixedly mounted on the tank and its output shaft is drivenly connected to the stirring shaft. The stirring shaft is rotatably mounted on the tank and one end extends into the tank. The stirring blades are fixedly mounted on the stirring shaft and located inside the tank. The stirring shaft has a first cavity along its length, and the first cavity stores heat-conducting oil. The heating element is located in the first cavity and is at least partially in contact with the heat-conducting oil.

[0007] The powder coating storage device uses a stirring motor to drive the stirring shaft and stirring blades to rotate, which can stir the powder coating stored in the tank, prevent the powder coating from clumping, and break up any clumped powder coating. By setting up a first cavity and filling the first cavity with heat-conducting oil, the heat-conducting oil can be quickly heated by a heating element, and the heat is transferred to the stirring blades through the stirring shaft to heat the powder coating stored in the tank, removing moisture from the powder coating and preventing it from absorbing moisture and clumping. In addition, compared with the existing drying method of heating powder coating by supplying hot air to the storage tank, by setting up a first cavity and storing heat-conducting oil in the first cavity, the powder coating storage device can also achieve the function of simultaneous stirring and heating drying, which can ensure that the powder coating is heated evenly and improve the drying and moisture-proofing efficiency.

[0008] Preferably, the stirring blade has a second cavity along its length, and the first cavity is connected to the second cavity.

[0009] Preferably, the stirring blades comprise multiple blades, which are evenly distributed along the length of the stirring shaft.

[0010] Preferably, the first cavity is provided with a receiving groove for installing the heating element, and the receiving groove is located inside the tank.

[0011] Preferably, the powder coating storage device further includes a cover plate and a support, the cover plate covering the tank body, the support plate being fixedly installed on the cover plate, and the stirring motor being fixedly installed on the support plate.

[0012] Preferably, the powder coating storage device further includes a bearing and a reinforcing rib, the stirring shaft passes through the bracket and the cover plate and is rotatably mounted on the bracket through the bearing, and the reinforcing rib is fixedly installed between the bearing and the bracket.

[0013] Preferably, the reinforcing rib comprises multiple pieces, which are evenly distributed along the circumference of the bearing.

[0014] Preferably, the powder coating storage device further includes a pulley and a belt, the pulley being fixedly installed at the other end of the stirring shaft, and the belt being sleeved on the pulley and the output shaft of the stirring motor.

[0015] Preferably, the cover plate is provided with a vent, and a filter sponge is provided inside the vent.

[0016] Preferably, the heat-conducting oil is immersed in the receiving tank. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with its embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit its scope of protection.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0028] like Figure 1 as well as Figure 2 As shown, a powder coating storage device according to one embodiment of the present invention includes a tank 1, a stirring motor 2, a stirring shaft 3, stirring blades 4, and a heating element 5. The tank 1 is used to store powder coating. The stirring motor 2 is fixedly installed on the tank 1. The output shaft of the stirring motor 2 is connected to the stirring shaft 3. The stirring shaft 3 is rotatably installed on the tank 1 and one end extends into the tank 1. The stirring blades 4 are fixedly installed on the stirring shaft 3 and located inside the tank 1.

[0029] Specifically, such as Figure 4 As shown, the powder coating storage device further includes a cover plate 6, a bracket 7, a pulley 8, and a belt 9. The cover plate 6 covers the tank body 1, the bracket 7 is fixedly installed on the cover plate 6, and the stirring motor 2 is fixedly installed on the bracket 7. The pulley 8 is fixedly installed on the other end of the stirring shaft 3, and the belt 9 is sleeved on the pulley 8 and the output shaft of the stirring motor 2. The pulley 8 is a solid wheel or a spoked wheel.

[0030] Preferably, the powder coating storage device further includes a bearing 10 and reinforcing ribs 11. The stirring shaft 3 passes through the bracket 7 and the cover plate 6 and is rotatably mounted on the bracket 7 via the bearing 10. The reinforcing ribs 11 are fixedly installed between the bearing 10 and the bracket 7. Multiple reinforcing ribs 11 are evenly distributed along the circumference of the bearing 10. By providing the reinforcing ribs 11, the bearing 10 can be securely mounted on the bracket 7, enhancing the stability of the stirring shaft 3 during rotation.

[0031] The bearing 10 includes two bearings, with the stirring shaft 3 passing through the inner rings of the two bearings 10. The outer ring of one bearing 10 is fixedly mounted on the bracket 7, and the other bearing 10 is located between the bracket 7 and the pulley 8. The side of the reinforcing rib 11 is fixedly connected to the outer ring of the bearing 10 and the bracket 7.

[0032] The stirring motor 2 drives the stirring shaft 3 to rotate via the pulley 8 and belt 9, thereby driving the stirring blades 4 to stir the powder coating in the tank 1. In this way, the powder coating can be prevented from clumping and can also be stirred and broken up if clumped.

[0033] like Figure 3 As shown, the stirring shaft 3 has a first cavity 12 along its length, which stores heat-conducting oil. The heating element is disposed within the first cavity 12 and is at least partially in contact with the heat-conducting oil. The heating element can be a heating wire. Here, a rotary conductive connector can be installed at the other end of the stirring shaft 3. The two ends of the rotary conductive connector are electrically connected to the heating element through a wire, and the rotary conductive connector is connected to a power source to supply power to the heating element.

[0034] Since the heat transfer oil is stored in the first cavity 12 and at least part of the heating element is in direct contact with the heat transfer oil, the heat transfer oil can be heated quickly by the heating element, thereby quickly transferring heat to the stirring shaft 3 and the stirring blades 4 to heat and dry the powder coating.

[0035] Preferably, the stirring blades 4 and the stirring shaft 3 can be made of metals with good thermal conductivity, such as aluminum alloys, to accelerate the heat transfer speed and efficiency of the heating element --> heat transfer oil --> stirring shaft 3 and stirring blades 4.

[0036] A vent is provided on the cover plate 6, and a filter sponge is installed inside the vent. The filter sponge allows evaporated moisture to escape during the mixing and drying process of the powder coating. Additionally, the filter sponge prevents dust and impurities from the outside air from falling into the tank 1 through the vent.

[0037] In summary, the powder coating storage device drives the stirring shaft 3 and stirring blades 4 to rotate via the stirring motor 2, which can stir the powder coating stored in the tank 1 to prevent the powder coating from clumping and to break up any clumped powder coating. By setting the first cavity 12 and filling the first cavity 12 with heat transfer oil, the heat transfer oil can be quickly heated by the heating element, and the heat can be transferred to the stirring blades 4 through the stirring shaft 3 to heat the powder coating stored in the tank 1, remove the moisture from the powder coating, and prevent the powder coating from absorbing moisture and clumping.

[0038] In addition, compared with the existing drying method of heating powder coatings by supplying hot air to the storage tank, by setting up the first cavity 12 and storing heat-conducting oil in the first cavity 12, the powder coating storage device can also realize the function of heating and drying while stirring, which can make the powder coatings heat evenly and improve the drying and moisture-proof efficiency.

[0039] As a preferred technical solution, such as Figure 5 As shown, the stirring blades comprise multiple pieces, which are evenly spaced along the length of the stirring shaft 3. Each stirring blade has a second cavity 13 along its length, and the first cavity 12 communicates with the second cavity 13.

[0040] Preferably, the first cavity 12 is provided with a receiving groove 14 for installing the heating element. The receiving groove 14 is located inside the tank body 1, and the heat transfer oil is immersed in the receiving groove 14. That is, the heating element is immersed in the heat transfer oil to improve the heat transfer efficiency between the heating element and the heat transfer oil.

[0041] The receiving tank 14 is located inside the tank body 1 rather than outside, which can also minimize the waste of heat and keep the heat emitted by the heating element inside the tank body 1 as much as possible for heating the powder coating.

[0042] The stirring blade 4 can be fixedly mounted on the stirring shaft 3 using a hollow headless screw. Specifically, the two ends of the hollow headless screw are respectively connected to the first cavity 12 and the second cavity 13, and the two ends are respectively threaded to the stirring shaft 3 and the stirring blade 4 through threaded holes.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
