Description

Technical Field

[0001] This utility model relates to the field of coating processing technology, and in particular to a fireproof coating grinding and processing device. Background Technology

[0002] Fire-retardant coatings are special coatings applied to the surface of combustible substrates to reduce the flammability of the coated material, inhibit the rapid spread of fire, and improve the fire resistance limit of the coated material. During the production process, fire-retardant coatings require strict stirring and grinding to ensure their uniformity and texture. This step is crucial to the quality and performance of fire-retardant coatings. Specifically, grinding ensures that the particle size of pigments and fillers is uniformly dispersed, avoiding problems such as powdering or shedding, thereby improving the overall performance of the coating.

[0003] Wet milling of fire-retardant coatings is a process in which an appropriate amount of liquid (usually water or a specific solvent) is added during the grinding process. Compared to dry milling, wet milling effectively reduces the heat generated during the grinding process, minimizing problems such as coating component deterioration or performance degradation caused by overheating, while also achieving a finer and more uniform grinding effect.

[0004] Existing fire-retardant coating grinding and processing equipment can only grind the coating at a fixed angle when grinding the coating. This can easily create grinding dead angles during the grinding process, thus reducing the grinding effect. Therefore, a fire-retardant coating grinding and processing equipment is proposed.

[0053] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper" and "lower" are used interchangeably with... Figure 1 The orientation is used as a reference.

[0054] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0055] like Figures 1 to 3 As shown in the embodiment of this application, a fire-retardant coating grinding and processing device is proposed, comprising: a supporting component 100 for supporting a supporting barrel 200 containing coating to be ground; an arc-shaped track component 300 disposed on the supporting component 100 and located at the top of the supporting barrel 200; a moving component 400 disposed on the arc-shaped track component 300 for moving along the track of the arc-shaped track component 300; and a grinding body 500 disposed on the moving component 400 for extending into the supporting barrel 200 to grind the coating; wherein the forward direction of the grinding body 500 extending into the supporting barrel 200 is a first direction, and the opening of the supporting barrel 200 is located in the first direction.

[0056] The fire-retardant coating grinding and processing device provided in this application embodiment includes a bearing component 100, an arc-shaped track component 300, a moving component 400, and a grinding body 500. During operation, a bearing bucket 200 containing the coating to be ground is mounted on the bearing component 100, and the arc-shaped track component 300 is fixedly mounted on the bearing component 100. An arc-shaped track is formed on the arc-shaped track component 300, and the moving component 400 is disposed on the arc-shaped track. The moving component 400 can move along the arc-shaped track. As described above, the grinding body 500 is disposed on the moving component 400. When the moving component 400 moves along the arc-shaped track, the grinding body 500 can also move along with it. During operation, the grinding body 500 extends into the bearing bucket 200 along a first direction to grind the coating.

[0057] As can be seen from the above, the moving component 400 can simultaneously drive the grinding body 500 to move along the arc-shaped track 300. At the same time, the grinding end of the grinding body 500 always extends into the bearing tank 200 along the first direction to grind the coating. When the grinding body 500 is under the action of the moving component 400, it can extend into the bearing tank 200 at different angles to grind the coating, which can greatly ensure the uniformity of the coating movement in the bearing tank 200, thereby effectively avoiding the formation of grinding dead angles during the grinding process, greatly improving the grinding effect, overcoming the defect of the existing device that the grinding body can only grind the coating at a fixed angle, significantly improving the comprehensiveness and effect of grinding, and providing a strong guarantee for the production of high-quality fireproof coatings.

[0058] For example, the support component 100 is provided with a locking component for fixing the support barrel 200, which can fix the support barrel 200 relative to the support component 100.

[0059] like Figures 1 to 3 As shown, in some examples, the moving component 400 includes: a support frame 410 slidably mounted on the arcuate track 300 along the arcuate track 300; and a drive gear 420 rotatably mounted on the support frame 410, the drive gear 420 being meshed with the arcuate track of the arcuate track 300.

[0060] In this technical solution, the moving component 400 includes a support frame 410 and a drive gear 420. The support frame 410 is slidably mounted on the arc-shaped track 300, and the drive gear 420 is rotatably mounted on the support frame 410. The drive gear 420 is driven by a motor. When the drive motor drives the drive gear 420 to rotate, it can drive the support frame 410 to move along the arc-shaped track 300 along the arc-shaped track that meshes with it, thereby adjusting the angle of the support frame 410 relative to the arc-shaped track 300.

[0061] For example, the support frame 410 can be made of aluminum alloy, which is lightweight and high-strength. While ensuring its own structural stability, it can effectively reduce the weight of the entire moving component 400, reduce energy consumption, and improve the smoothness of device operation. At the same time, for example, the support frame 410 can be installed on the arc-shaped track component 300 by means of a slider and a slide rail. The slider is equipped with a rolling bearing, which can minimize the frictional resistance between the slider and the slide rail, making the sliding process of the support frame 410 smoother, and effectively reducing wear and heat caused by friction, thus extending the service life of the component.

[0062] For example, when the drive gear 420 meshes with the arc-shaped track component 300, it can achieve smooth and efficient power transmission, reduce impact and vibration during the transmission process, and ensure the smoothness and accuracy of the movement.

[0063] In practical operation, the drive mechanism drives the drive gear 420 to rotate. Since the drive gear 420 meshes with the arc track 300, according to the gear transmission principle, the rotational motion of the drive gear 420 is converted into the sliding motion of the support frame 410 along the arc track 300. This, in turn, drives the grinding body 500 installed on the support frame 410 to move along the arc track, allowing the grinding body 500 to extend into the bearing barrel 200 at different angles to grind the coating. This significantly improves the comprehensiveness and uniformity of coating grinding, thereby improving the grinding effect and laying a solid foundation for the production of high-quality fireproof coatings.

[0064] like Figure 1 and Figure 2 As shown, in some examples, the grinding body 500 includes: a grinding shell 510, fixedly connected to the moving component 400, a first grinding cavity 501 formed inside the grinding shell 510 for carrying grinding balls, an inlet and an outlet formed at the top and bottom of the grinding shell 510 respectively, the direction from the inlet to the outlet being a second direction; a first filter screen 520 disposed at the inlet; a drive spindle 530 rotatably mounted inside the first grinding cavity 501; at least two drive blades 540 disposed on the drive spindle 530; and a second filter screen 550 disposed at the outlet; wherein, when the drive blades 540 rotate, the coating material in the first grinding cavity 501 flows along the second direction.

[0065] In this technical solution, the grinding body 500 includes a grinding shell 510, a first filter screen 520, a drive spindle 530, a drive fan blade 540, and a second filter screen 550. The grinding shell 510 is fixedly connected to the moving component 400, ensuring relative fixation between the grinding shell 510 and the moving component 400, and stability during movement. A first grinding cavity 501 is formed inside the grinding shell 510 to hold the grinding balls. The grinding balls in the first grinding cavity 501 grind the coating material within it. The first filter screen 520 is located at the feed inlet, ensuring that the coating material enters the first grinding cavity 501 while preventing the grinding balls from escaping. The main shaft 530 is rotatably mounted in the first grinding chamber 501. For example, its two ends can be mounted on the grinding housing 510 through bearings, providing stable and reliable support for the drive main shaft 530 and ensuring that the drive main shaft 530 can rotate accurately in the preset direction and speed. At least two drive blades 540 are arranged on the drive main shaft 530. When the drive main shaft 530 rotates, it drives the drive blades 540 to rotate, which can generate sufficient driving force to drive the coating to flow in the second direction in the first grinding chamber 501. The drive blades 540 are streamlined blade structures, which can reduce fluid resistance while maximizing the driving efficiency of the coating, so that the coating forms a uniform and orderly flow path in the first grinding chamber.

[0066] As can be seen from the above, when the drive fan blade 540 rotates, the coating material in the first grinding chamber 501 flows along the second direction. When the drive spindle 530 drives the drive fan blade 540 to rotate at high speed, the drive fan blade 540 cuts the coating material at high speed, generating a strong pressure difference, which causes the coating material to flow in the first grinding chamber in the predetermined second direction. After the coating material enters from the feed port, it first passes through the first filter screen 520 for preliminary filtration. Then, under the push of the drive fan blade 540, it fully contacts, collides and rubs with the grinding balls in the first grinding chamber 501 to complete the grinding process. After that, the ground coating material flows to the discharge port under the continued push of the drive fan blade 540 and is discharged after secondary filtration by the second filter screen 550.

[0067] like Figure 1 and Figure 2 As shown, in some examples, the drive spindle 530 includes: a drive shaft 531, rotatably mounted in the first grinding chamber 501; a driven tube 532, coaxially rotatably mounted on the drive shaft 531; and a transmission gear set 533, disposed between the drive shaft 531 and the driven tube 532, for causing the drive shaft 531 and the driven tube 532 to rotate in opposite directions; wherein, two drive fan blades 540 are respectively disposed on the drive shaft 531 and the driven tube 532.

[0068] In this technical solution, the drive shaft 531 is rotatably mounted inside the first grinding chamber 501. It is the core power transmission component for driving the main shaft 530 and is driven by a drive motor. The driven tube 532 is coaxially rotatably mounted on the drive shaft 531. For example, a sliding bearing and a guide keyway structure are provided between the inner wall of the driven tube 532 and the outer wall of the drive shaft 531 to support the smooth rotation of the driven tube 532 relative to the drive shaft 531. A transmission gear set 533 is disposed between the drive shaft 531 and the driven tube 532 to make the drive shaft 531 and the driven tube 532 rotate in opposite directions. For example, the transmission gear set 533 consists of meshing bevel gears.

[0069] Two drive blades 540 are respectively disposed on the drive shaft 531 and the driven tube 532. When the drive shaft 531 rotates, the drive blades 540 on the drive shaft 531 push the coating material in one direction. Under the action of the transmission gear set 533, the driven tube 532 rotates in the opposite direction to the drive shaft 531, so that the drive blades 540 on the driven tube 532 push the coating material in the opposite direction. In this way, a complex, interlaced and sufficient coating material flow path is formed in the first grinding chamber 501. Under this bidirectional and interlaced pushing action, the coating material can more comprehensively and evenly scour and contact the grinding balls, which greatly increases the collision probability and contact time between the coating material and the grinding balls, effectively improving the grinding quality and efficiency, and fully avoiding the problem of uneven and incomplete grinding caused by pushing the coating material in a single direction in the prior art.

[0070] like Figure 1 and Figure 2 As shown, in some examples, the grinding body 500 further includes an auxiliary sieve barrel 560 disposed within the first grinding chamber 501, wherein a second grinding chamber 502 is formed inside the auxiliary sieve barrel 560 for carrying the grinding balls, and the second grinding chamber 502 is connected to the feed inlet.

[0071] In this technical solution, the grinding body 500 also includes an auxiliary sieve barrel 560, which is disposed in the first grinding chamber 501. The cylindrical shape helps to provide a larger screening and grinding area in a limited space, so that the coating can come into full contact with the grinding balls and the inner wall of the auxiliary sieve barrel 560.

[0072] During operation, when the coating material to be ground enters through the feed inlet, it flows directly into the second grinding chamber 502 of the auxiliary sieve barrel 560. The coating material entering the second grinding chamber 502 undergoes preliminary grinding and screening under the action of the grinding balls. After being ground and screened by the second grinding chamber 502, the coating material passes through the auxiliary sieve barrel 560 and enters the first grinding chamber 501, further improving the overall refining ability of the coating material during the grinding process.

[0073] In some examples, the screening accuracy of the first filter 520, the auxiliary sieve barrel 560, and the second filter 550 gradually increases.

[0074] like Figure 2 As shown, in some examples, the grinding body 500 further includes: a first auxiliary rod 570, disposed on the driven tube 532, for actuating the grinding ball. The grinding body 500 also includes: a second auxiliary rod 580, disposed on the drive shaft 531 and located within the first grinding cavity 501, for actuating the grinding ball within the first grinding cavity 501.

[0075] In this technical solution, the grinding body 500 also includes a first auxiliary rod 570 and a second auxiliary rod 580, wherein the first auxiliary rod 570 is disposed on the driven tube 532 and the second auxiliary rod 580 is disposed on the drive shaft 531, both of which are used to actuate the grinding ball.

[0076] When the driven tube 532 rotates under the drive of the main shaft 530, the first auxiliary rod 570 rotates synchronously. During its rotation, it periodically contacts and agitates the grinding balls in the second grinding chamber 502. This agitation makes the distribution of the grinding balls in the chamber more uniform, effectively reducing the accumulation or stagnation of grinding balls in certain areas. This allows the coating to make more thorough contact with the grinding balls at all locations for grinding, greatly improving the uniformity and efficiency of grinding.

[0077] Similarly, when the drive shaft 531 rotates at high speed, the second auxiliary rod 580 also rotates at high speed in the first grinding chamber 501. The movement of the second auxiliary rod 580 not only allows some previously inactive grinding balls to regain kinetic energy and increases the overall kinetic activity of the grinding balls, but also complements the effect of the first auxiliary rod 570, forming a complex and orderly grinding ball movement environment in the first grinding chamber. This environment can promote the collision, friction, and mixing between the coating and the grinding balls in all directions, so that the coating can be uniformly crushed and dispersed throughout the grinding process, greatly improving the grinding quality and effect, and reducing the possibility of quality problems such as uneven particle size and insufficient grinding. Through the synergistic effect of the first auxiliary rod 570 and the second auxiliary rod 580, the grinding performance of the entire grinding body 500 is further improved.

[0078] The grinding body 500 further includes grinding protrusions 590 formed on the side wall of the auxiliary sieve barrel 560. Through the synergistic action of the grinding protrusions 590 and the grinding balls, the coating material can be ground more effectively.

[0079] like Figures 1 to 2As shown, in some examples, the fire-retardant coating grinding and processing device further includes: a telescopic drive 600, disposed between the moving component 400 and the grinding body 500, for driving the grinding body 500 to move toward or away from the carrying barrel 200.
