Ultrafine powder coating cyclone separator

Abstract

This utility model discloses an ultrafine powder coating cyclone separator, specifically relating to the field of powder processing technology. It includes a separation cylinder with a separation assembly. The separation assembly includes two central separation discs located in the middle of the cylinder. A first sealing disc is located at one end of the cylinder, and a second sealing disc is located at the other end. This utility model utilizes two parallel, rotatable central separation discs in the middle of the cylinder, with several sieve holes of specific diameters perforated through the discs. Driven by a motor, the central separation discs rotate, generating centrifugal force. Coarse powder coating particles, due to their large mass and strong centrifugal force, cannot pass through the sieve holes and are ultimately discharged from the discharge pipe. Ultrafine powder, however, passes through the sieve holes with the airflow and is recovered through the powder discharge pipe. This achieves forced separation of coarse and fine materials, fundamentally avoiding mixing, and the separation accuracy meets the requirements for the production and recycling of ultrafine powder coatings.

Description

Technical Field

[0001] This utility model relates to the field of powder processing technology, and more specifically, to an ultrafine powder coating cyclone separator. Background Technology

[0002] Metal powder refers to an aggregate of fine particles made of metal or its alloys, with particle sizes ranging from micrometers to nanometers. It retains the basic properties of metals (such as electrical conductivity, thermal conductivity, and ductility), while the miniaturization of particle size results in a series of unique physical, chemical, and mechanical properties. The ultrafine powder coating cyclone separator is a highly efficient solid-gas separation device specifically designed for ultrafine powder coatings. Its core function is to separate and recover ultrafine powder coating particles from dust-laden airflow, while simultaneously purifying the gas. It is widely used in powder coating production, spraying (such as electrostatic spraying), and recovery processes.

[0003] Among them, the patent with publication number CN203990841U discloses an ultrafine powder coating separation device, which includes a tablet cooling crusher, a receiving hopper, a grinding mill, a cyclone separator, a bag filter and an induced draft fan connected in sequence. When in use, this structure recovers materials through a grinding mill, which includes a frame, a closed cylinder, a drive mechanism, a motor, and a grinding mechanism set inside the closed cylinder. However, it is difficult to accurately separate and divert materials, often resulting in the mixing of fine powder and particulate coatings, leading to poor separation and failing to meet the requirements of high-precision production. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides an ultrafine powder coating cyclone separator, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: an ultrafine powder coating cyclone separator, including a separation cylinder, on which a separation component is provided; The separation assembly includes two central separation discs disposed in the middle of the separation cylinder. A first sealing disc is disposed at one end of the separation cylinder, and a second sealing disc is disposed at the other end of the separation cylinder. The bottom of the inner walls of the first sealing disc and the second sealing disc are provided with frame openings. The bottom of the separator cylinder is provided with a discharge pipe extending between two central separator discs. A feed pipe is provided on one side of the discharge pipe, and a powder discharge pipe is provided on the other side of the discharge pipe.

[0006] Optionally, in a possible implementation, guide grooves are provided on both sides of the bottom of the separator, and each guide groove is connected to a corresponding frame opening. The feed pipe is connected to the frame opening to which the first sealing disc belongs, and the powder discharge pipe is connected to the frame opening to which the second sealing disc belongs. Optionally, in a possible implementation, a drive motor is bolted to the second sealing disc, the output end of the drive motor extends to the central separation disc, and locking blocks are respectively provided on both sides of the separation cylinder. Gear rings are respectively fitted on the outer sides of the first and second sealing discs, and the locking blocks engage with the gear rings. The two central separation discs are arranged side by side, and each of the central separation discs is rotatably connected to the separation cylinder. Several sieve holes are opened through the two central separation discs. The technical effects and advantages of this utility model are as follows: Two parallel, rotatable central separation discs are positioned in the middle of the separation cylinder, with several sieve holes of a specific diameter running through the discs. Driven by a motor, the central separation discs rotate, generating centrifugal force. Coarse particles of coating, due to their large mass and strong centrifugal force, cannot pass through the sieve holes and are ultimately discharged from the discharge pipe; ultrafine powder, however, passes through the sieve holes with the airflow and is recovered through the powder discharge pipe. This achieves forced separation of coarse and fine materials, fundamentally avoiding mixing, and the separation accuracy meets the requirements for the production and recycling of ultrafine powder coatings.

[0007] The guide channels on both sides of the bottom of the separator are connected to the frame openings of the first and second sealing discs, and the guide channels adopt an optimized inclined design. On the one hand, this guides the dust-laden airflow smoothly into the separation area from the feed pipe, avoiding airflow turbulence that could affect the separation; on the other hand, it quickly transports the separated coarse particles and ultrafine powders, preventing material from accumulating and clogging inside the equipment, and ensuring a continuous and efficient separation process.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] The ultrafine powder coating cyclone separator disclosed in this embodiment has the following overall structure: Figure 1 As shown, the device includes a separation cylinder 1, which serves as the core load-bearing component, providing a stable framework for the installation and operation of subsequent components. A separation assembly is installed on the separation cylinder 1, which is a key structure for achieving efficient material separation.

[0016] The separation assembly specifically includes two central separation discs 2 located in the middle of the separation cylinder 1, as shown in the attached diagram. Figure 2 Appendix Figure 3 Appendix Figure 4 As shown, two central separation discs 2 are arranged side by side and are rotatably connected to the separation cylinder 1. This rotatable connection ensures that the central separation discs 2 can rotate flexibly during subsequent operations, providing power support for material separation. Meanwhile, several sieve holes 13 are drilled through both central separation discs 2. The aperture of the sieve holes 13 is precisely designed to allow only ultrafine powder coating particles that meet the requirements to pass through, laying the foundation for achieving the separation of coarse and fine materials.

[0017] A first sealing disc 3 is provided at one end of the separation cylinder 1, and a second sealing disc 4 is provided at the other end. The first sealing disc 3 and the second sealing disc 4 cooperate with the separation cylinder 1 to effectively seal the internal space of the separation cylinder 1, preventing the leakage of dust-laden airflow during the separation process, and ensuring the high efficiency and environmental friendliness of the separation operation. (See attached image) Figure 1 Appendix Figure 3 As shown, locking blocks 11 are respectively provided on both sides of the separation cylinder 1, and toothed rings 12 are respectively fitted on the outer sides of the first sealing disc 3 and the second sealing disc 4. The locking blocks 11 and the toothed rings 12 are engaged. Through the cooperation of the locking blocks 11 and the toothed rings 12, the installation and disassembly of the first sealing disc 3, the second sealing disc 4 and the separation cylinder 1 can be quickly realized, which facilitates the maintenance and repair of the equipment.

[0018] As attached Figure 1 Appendix Figure 2 Appendix Figure 4 As shown, frame openings 5 ​​are provided at the bottom of the inner walls of the first sealing disc 3 and the second sealing disc 4. Guide channels 9 are respectively provided on both sides of the bottom of the separation cylinder 1, and the two guide channels 9 are connected to the corresponding frame openings 5. The guide channels 9 adopt an inclined structure design, and their inclination angle has been optimized to guide the smooth flow of materials and prevent material accumulation and blockage during transmission.

[0019] The bottom of the separator 1 is provided with a discharge pipe 6 extending between the two central separator discs 2. A feed pipe 7 is provided on one side of the discharge pipe 6, and a powder discharge pipe 8 is provided on the other side, as shown in the attached diagram. Figure 1 Appendix Figure 2 Appendix Figure 4 As shown. The feed pipe 7 is connected to the frame opening 5 of the first sealing disc 3. The dust-laden airflow can enter through the feed pipe 7 and be transported to the central separation disc 2 area inside the separation cylinder 1 through the frame opening 5 at the bottom of the first sealing disc 3 and the corresponding guide groove 9. The powder discharge pipe 8 is connected to the frame opening 5 of the second sealing disc 4. The separated ultrafine powder can be discharged through the frame opening 5 at the bottom of the second sealing disc 4, the corresponding guide groove 9 and the powder discharge pipe 8.

[0020] In addition, as attached Figure 1 As shown, a drive motor 10 is bolted to the second sealing disc 4, and the output end of the drive motor 10 extends to the central separation disc 2. The drive motor 10 is a model with stable output power, and the bolted installation method not only ensures a secure connection but also facilitates disassembly and maintenance in case of subsequent drive motor 10 failure. When the drive motor 10 starts, it can drive the central separation disc 2 to rotate around the central axis of the separation cylinder 1, providing the necessary centrifugal force for the separation process of materials within the separation cylinder 1. The specific working principle is as follows: When the ultrafine powder coating cyclone separator starts working, the drive motor 10 on the second sealing disc 4 is first started. The drive motor 10 drives the two central separation discs 2, which are arranged side by side and rotatably connected to the separation cylinder 1, to rotate. Subsequently, the dust-laden airflow enters from the feed pipe 7. Since the feed pipe 7 is connected to the frame opening 5 of the first sealing disc 3, the dust-laden airflow is smoothly transported through the frame opening 5 at the bottom of the first sealing disc 3 and the corresponding guide groove 9 to the space between the two central separation discs 2 inside the separation cylinder 1.

[0021] Under the centrifugal force generated by the rotation of the central separation disc 2, the material in the dust-laden airflow is subjected to the combined effects of centrifugal force and airflow resistance. Among them, the larger paint particles, due to their greater mass, experience greater centrifugal force and cannot pass through the sieve holes 13 on the central separation disc 2. Driven by centrifugal force, they gradually move towards the inner wall of the separation cylinder 1, and finally, under the action of gravity, they are discharged from the bottom of the separation cylinder 1 through the discharge pipe 6 between the two central separation discs 2, thus completing the separation and recovery of coarse particles.

[0022] The ultrafine powder coating particles, due to their small mass, experience less centrifugal force and can easily pass through the sieve holes 13 on the central separation disk 2 under the influence of airflow. After passing through the sieve holes 13, the ultrafine powder moves towards the second sealing disk 4 under the guidance of airflow, and is then discharged through the frame opening 5 at the bottom of the second sealing disk 4, the corresponding guide groove 9, and the powder discharge pipe 8 connected to the frame opening 5, thus achieving the separation and recovery of the ultrafine powder. Simultaneously, the purified gas is discharged from the corresponding outlet of the separation cylinder 1 under the subsequent airflow, completing the entire solid-gas separation and gas purification process.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
