Description

Technical Field

[0001] This utility model relates to the field of iron oxide preparation technology, specifically a high-speed dispersion device for coating iron oxide. Background Technology

[0002] In the prior art, iron oxide surface coating is a technique that forms one or more coating layers on the surface of iron oxide through physical or chemical methods. The purpose is to improve the stability, dispersibility, functionality, or compatibility of iron oxide with other materials. It can effectively improve the stability of iron oxide, prevent iron oxide from oxidizing, hydrolyzing, or agglomerating in humid, high-temperature, or corrosive environments, and improve dispersibility by adjusting the surface polarity through the coating layer, so that it can be uniformly dispersed in water, organic solvents, or polymer matrices.

[0003] In existing technologies, coating is mainly achieved through two methods: chemical and physical. Chemical methods primarily utilize gelation or precipitation to achieve coating, and the coating process requires strict control of various data to improve coating quality. Physical methods, on the other hand, can achieve coating through physical adsorption and mechanical coating. Mechanical coating, in particular, uses mechanical forces such as grinding and high-speed stirring to adhere the coating material to the surface of iron oxide, thereby achieving coating. It is especially suitable for large-scale industrial production, such as the coating of pigment particles.

[0004] For example, in the prior art, the "high-speed dispersion equipment" mentioned in the "a coating technology for iron oxide surface" disclosed in the authorization announcement number: CN110449575B, the main technical solution is to put the iron oxide powder to be coated and the thin tin powder into the high-speed dispersion equipment for high-speed dispersion, so that the tin layer aluminum powder is uniformly adhered to the surface of the iron oxide powder, thereby obtaining alloy powder. In addition, the high-speed dispersion equipment in this technical solution is also equipped with three layers of screening screens, which can screen the iron oxide powder through the screening screens while the high-speed dispersion coating is being carried out. When the coating is completed, the screening is completed at the same time, achieving two goals at once.

[0005] However, in the above technical solution, on the one hand, the specific structure of the "high-speed dispersion equipment" in the above technical solution is not disclosed, which makes it impossible to understand how the high-speed dispersion equipment disperses, how the iron oxide powder is layered, and the setting of the driving power equipment, etc., so it is impossible to understand its working principle and structure.

[0006] Another important point is that, in order to achieve simultaneous coating and sieving in the above technical solution, three layers of screening mesh are set in the same dispersion device. With this design, the iron oxide powder entering can be screened through the three layers of powder with different particle sizes. However, the particle size of the thin tin powder entering is smaller than that of the iron oxide powder. Therefore, the thin tin powder will fall directly onto the bottom screening mesh, resulting in very little thin tin powder on the upper screening mesh. As a result, the thin tin powder falls onto the lower screening mesh, which will seriously affect the coating of the upper iron oxide powder, severely impacting the work quality and efficiency.

[0007] Therefore, in order to solve the above problems, it is necessary to develop a high-speed dispersion device for iron oxide coating with a reasonable structure that improves efficiency and quality. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-speed dispersion device for coating iron oxide; the technical solution is as follows:

[0009] A high-speed dispersion device for coating iron oxide includes a workbench with a station slot inside. A rotary motor is embedded in the middle of the station slot, and a dispersion box is mounted on the main shaft of the rotary motor. An annular inner mesh plate and an outer mesh plate are also installed inside the dispersion box. The area inside the inner mesh plate is defined as a first dispersion area, the area between the inner and outer mesh plates is defined as a second dispersion area, and the area between the outer mesh plate and the side wall of the dispersion box is defined as a third dispersion area.

[0010] Furthermore, a detachable sealing cover is fitted on the outside of the inner mesh plate. The inner diameter of the sealing cover corresponds to the outer diameter of the inner mesh plate. After the iron oxide powder to be coated and the coating material are placed into the first dispersion area, the inner mesh plate is completely covered from the outside by the sealing cover, thereby completely covering the space of the first dispersion area. The iron oxide powder and the coating material are located in the sealed first dispersion area and rotate accordingly under the drive of the rotary motor. After the coating is completed, the sealing cover can be completely removed upwards, and the rotary motor continues to drive the dispersion box to rotate to complete the screening.

[0011] Furthermore, the mesh diameter of the inner mesh plate is larger than that of the outer mesh plate, thereby screening iron oxide powders of different particle sizes. The technical solution of this device is mainly to achieve screening after coating is completed. Therefore, it is necessary to design the mesh diameter of the inner and outer mesh plates accordingly. In this device, both mesh plates are plate-shaped, but the plates are provided with smaller mesh holes. The overall structure is a mesh-like plate structure, which can realize screening. This is a very common design in the prior art, and the structure is reasonably set.

[0012] Furthermore, the inner mesh plate has a recessed vertical groove on its outer wall, and the sealing cover has a vertical block on its vertical plate corresponding to the vertical groove. The sealing cover can be detachably installed by the cooperation of the vertical groove and the vertical block. The installation of the sealing cover is a critical issue in this device. If the sealing cover is directly fitted onto the outside of the inner mesh plate, it may separate during rotation. Therefore, this device is equipped with vertical blocks and vertical grooves. The detachable installation is achieved through the cooperation of the grooves and blocks, resulting in a reasonable structural design.

[0013] Furthermore, the bottom of the work station slot is provided with evenly distributed ball grooves, and each ball groove is also equipped with a supporting ball. When the dispersion box is placed in the work station slot, it is placed on the supporting ball. The structure design of ball grooves and supporting balls is a common design in the prior art. This device also adopts this design to stabilize the structure. The dispersion box is placed on the supporting ball during specific installation. Therefore, the overall structure is very stable, and the internal dispersion box can rotate relatively stably.

[0014] Furthermore, the inner and outer mesh plates are at the same height, and the height of the sealing cover is greater than that of the inner mesh plate, so that the bottom of the sealing cover is correspondingly fitted into the bottom of the dispersion box. In this device, it is necessary to ensure that the sealing cover completely covers the inner mesh plate, so the height of the sealing cover needs to be set accordingly, so that the higher the sealing cover is, the more airtight the first dispersion area can be achieved, and the structural design will be more reasonable.

[0015] Furthermore, an electric heating rod is also installed at the upper end of the sealing cover. The electric heating rod is inserted into the sealing cover from the upper end and heats the area inside the sealing cover. When the sealing cover is installed outside the inner mesh plate, the first dispersion area is heated by the electric heating rod. The heating form of electric heating rods already exists in the prior art. For example, commonly used heating devices such as "hot water heaters" are designed in the form of electric heating rods. Therefore, there are no difficulties in designing this technical solution.

[0016] Furthermore, the heating rods on the sealing cover are evenly distributed, and a lifting ring is also installed on the sealing cover. With the help of external equipment and the lifting ring, the sealing cover can be disassembled upwards. The even distribution of heating rods can effectively improve the temperature rise, and the design of the lifting ring is for disassembling the sealing cover using tools or external equipment. The structural design is also quite reasonable.

[0017] Beneficial effects: This utility model has the following beneficial effects:

[0018] 1) The technical solution of this device can simultaneously achieve the coating and sieving of iron oxide powder. The coating of iron oxide powder can be achieved first, and then the sieving can be achieved through the design of the sealing cover. It can also improve the coating effect and coating quality of iron oxide powder and improve the coating efficiency.

[0019] 2) In this device, the outer side of the inner mesh plate can be covered by the sealing cover, thus sealing the first dispersion area. After iron oxide powder and thin tin powder are placed into the first dispersion area of ​​the inner mesh plate, the iron oxide powder is coated by the sealing cover. Since the iron oxide powder and thin tin powder are mixed in the first dispersion area without being sieved, sufficient coating work can be carried out, effectively improving the coating effect and coating quality.

[0020] 3) After the coating is completed, the first dispersion area can be opened by removing the upper sealing cover in this device. The sieving of the coated iron oxide powder can be achieved by the mesh diameter design of the inner and outer mesh plates. The sieving is achieved after coating, and the structure design is reasonable.

[0021] 4) The sealing cover of this device is also equipped with an electric heating rod and a lifting ring. The design of the electric heating rod can provide heat to the area after the first dispersion area is sealed, thereby raising the internal temperature and providing the temperature required for the wrapping, thus improving the wrapping effect. The designed push-pull switch can be used to disassemble the sealing cover after the wrapping is completed using externally designed cranes and other equipment. The structure is reasonably designed.

Detailed Implementation

[0029] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0030] like Figure 1 and Figure 2 As shown, a high-speed dispersion device for coating iron oxide includes a workbench 1, a work station trough 2 is provided in the workbench 1, a rotary motor 3 is embedded in the middle of the work station trough 2, a dispersion box 4 is mounted on the main shaft of the rotary motor 3, and an annular inner mesh plate 5 and an outer mesh plate 6 are also installed in the dispersion box 4. The area within the inner mesh plate 5 is designated as a first dispersion area 7, the area between the inner mesh plate 5 and the outer mesh plate 6 is designated as a second dispersion area 8, and the area between the outer mesh plate 6 and the side wall of the dispersion box 4 is designated as a third dispersion area 9.

[0031] like Figure 3 As shown, a detachable sealing cover 10 is also fitted on the outside of the inner mesh plate 5. The inner diameter of the sealing cover 10 corresponds to the outer diameter of the inner mesh plate 5. After the iron oxide powder to be coated and the coating material are placed into the first dispersion area 7, the inner mesh plate 5 is completely covered from the outside by the sealing cover 10, thereby completely covering the space of the first dispersion area 7. The iron oxide powder and the coating material are located in the sealed first dispersion area 7 and rotate accordingly under the drive of the rotary motor 3. After the coating is completed, the sealing cover 10 can be completely removed upwards. The rotary motor 3 continues to drive the dispersion box 4 to rotate to complete the screening.

[0032] like Figure 4 As shown, the mesh diameter of the inner mesh plate 5 is larger than that of the outer mesh plate 6, thereby screening iron oxide powder of different particle sizes; a recessed vertical groove 11 is provided on the outer wall of the inner mesh plate 5, and a vertical block 12 corresponding to the position of the vertical groove 11 is provided on the vertical plate of the sealing cover 10. The sealing cover 10 can be detachably installed by the cooperation of the vertical groove 11 and the vertical block 12.

[0033] The bottom of the work station trough 2 is also provided with evenly distributed ball grooves 13, and each ball groove 13 is also equipped with a supporting ball 14. When the dispersion box 4 is placed in the work station trough 2, it is placed on the supporting ball 14. The inner mesh plate 5 and the outer mesh plate 6 have the same height, and the height of the sealing cover 10 is greater than the height of the inner mesh plate 5, so that the bottom of the sealing cover 10 is correspondingly clamped to the bottom of the dispersion box 4.

[0034] like Figure 5 The upper end of the sealing cover 10 is also equipped with an electric heating rod 15. The electric heating rod 15 is inserted into the sealing cover 10 from the upper end of the sealing cover 10 and heats the area inside the sealing cover 10. When the sealing cover 10 is installed outside the inner mesh plate 5, the first dispersed area 7 is heated by the electric heating rod 15. The electric heating rods 15 on the sealing cover 10 are evenly distributed, and a lifting ring 16 is also installed on the sealing cover 10. With the cooperation of the lifting ring 16, the sealing cover 10 can be removed upward by external equipment.

[0035] The technical solution of this device differs from the "high-speed dispersion equipment" in the existing patent announcement CN110449575B, which discloses "a surface coating technology for iron oxide." The latter has a vertical structure with three layers of screening mesh for top-to-bottom sieving, while this device has a horizontal structure. The dispersion box 4 has vertical inner and outer mesh plates 5 and 6, dividing the internal space into a first dispersion region 7, a second dispersion region 8, and a third dispersion region 9. However, although this device is horizontally designed, direct dispersion yields the same result as the disclosed technology because the incoming coating material (thin tin powder)... The iron oxide powder will still be directly thrown into the third dispersion zone 9 under the action of centrifugal force. Therefore, the iron oxide powder in the first dispersion zone 7 and the second dispersion zone 8 will also not be coated by the coating material, which will seriously affect the coating effect. Therefore, the technical solution of this device is to use a sealing cover 10 to ensure that coating and screening of the coated iron oxide powder can be achieved. In this device, two layers of circumferential inner mesh plates 5 and outer mesh plates 6 are first set in the dispersion box 4. The diameters of the two mesh plates are different, thus enabling screening. However, a sealing cover 10 is specifically fitted over the outer side of the inner mesh plate 5. The outer sealing cover 10 can completely cover the annular inner mesh plate 5, thus making the space inside the inner mesh plate 5 closed. With the space secured, the internal materials won't leak out. In specific operation, first remove the sealing cover 10, then place the iron oxide to be coated and the coating material together into the first dispersion area 7 of the inner mesh plate 5. Then, the sealing cover 10 is fitted over the inner mesh plate 5, thus sealing the first dispersion area 7, creating a closed space. At this point, the rotary motor 3 is started to rotate the entire dispersion box 4. Since the first dispersion area 7 is sealed by the sealing cover 10, the iron oxide powder and coating material mix and coat within the first dispersion area 7. Rotational dispersion adsorbs and coats the thin tin powder onto the iron oxide powder, achieving coating. After coating is complete, the sealing cover 10 can be removed. After the sealing cover 10 is removed, the first dispersion area 7 is opened. At this time, when the dispersion box 4 is rotated by the rotary motor 3, the coated iron oxide powder will be screened by the inner mesh plate 5 and the outer mesh plate 6 under the action of centrifugal force, and iron oxide powder of different particle sizes will be screened out. Subsequently, the iron oxide powder can be taken out from each dispersion area by equipment such as a suction fan. This device can also realize the coating and screening of iron oxide powder, but it is not done simultaneously. The screening is completed after the coating is completed by disassembling the sealing cover 10. However, since the iron oxide powder and thin tin powder are mixed together during the overall coating, the coating effect and coating quality can be significantly improved.

[0036] In this device, a workstation slot 2 is set inside the workbench 1, and the entire dispersion box 4 is placed inside the workstation slot 2. The dispersion box 4 is rotated by a rotary motor 3. The structural design is very common and can be achieved in existing technologies. In order to increase the smoothness of rotation, a ball groove 13 and a supporting ball 14 are set at the bottom of the workstation slot 2 to support the entire dispersion box 4. The structural design is very reasonable. In addition, this device specifically sets up an inner mesh plate 5 and a sealing cover 10. The sealing cover 10 and the inner mesh plate 5 are provided with vertical slots 11 and vertical blocks 12 that are designed to fit together, so that the inner mesh plate 5 and the sealing cover 10 can be installed accordingly, allowing them to be easily assembled and disassembled. Since the iron oxide powder and thin tin powder need to be coated with a certain temperature, an electric heating rod 15 is also installed at the upper end of the sealing cover 10. The electric heating rod 15 extends downward into the cover body. So when the sealing cover 10 is fitted onto the inner mesh plate 5, the electric heating rod 15 extends into the first dispersion box. Within area 7, the heating rod 15 can provide temperature during the coating process. The increased temperature inside the sealing cover 10 accelerates coating efficiency and improves quality. Since the heating rod 15 extends directly into the interior and is evenly distributed, the temperature rises quickly, and the temperature distribution is very uniform with rotation. Regarding the power supply for the heating rod 15, a battery or similar device can be installed on the sealing cover 10, a common design in existing technology. The structural design of the heating rod 15 is also common in existing technology, so this structural design is not described in detail. Furthermore, since the sealing cover 10 needs to be removed after heating, and its temperature is very high at this point, manual removal is not feasible. Therefore, this device also includes lifting rings 16 on both sides of the sealing cover 10, allowing for removal using external hoisting equipment. This structural design is quite reasonable and allows for removal without manual intervention.

[0037] The above-described specific embodiments are merely preferred embodiments of this utility model and are not intended to limit the implementation of this utility model or the scope of the claims. All equivalent changes and modifications made in accordance with the scope of protection of this utility model patent application should be included within the scope of this utility model patent application.
