Description

Technical Field

[0001] This utility model relates to the field of pigment production technology, specifically a filtration device for pigment production. Background Technology

[0002] In the pigment production industry, the crushing and filtration of raw materials are crucial; however, existing pigment production equipment has many problems in these areas.

[0003] On the one hand, during the cyclic crushing process of excessively large raw materials, the performance of some crushing devices is suboptimal, making it difficult to completely crush the pigment raw materials to the required particle size. This results in unsatisfactory crushing effects, requiring repeated cyclic crushing operations. This repeated crushing not only directly reduces overall production efficiency and extends the production cycle, but also increases energy consumption and production costs. At the same time, frequent and excessive operation of the equipment accelerates equipment wear, shortens its service life, and increases the cost of equipment maintenance and replacement.

[0004] On the other hand, pulverizing and filtering devices are prone to clogging after prolonged operation. Since pigment slurries often contain fine particles or fibrous impurities, these impurities easily accumulate on the filtering device during the filtration process, especially during circulating pulverization. Clogging not only significantly reduces filtration efficiency and slows down the filtration process, but it can also adversely affect the normal operation of the pulverizing mechanism, leading to a further decrease in circulating pulverization efficiency and seriously impacting the continuity and stability of pigment production. Therefore, this case study was developed to address these issues in depth. Utility Model Content

[0013] This utility model provides a filtration device for pigment production.

[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0020] Please see Figure 1-3 In existing pigment production processes, some grinding devices may fail to completely pulverize pigment raw materials to the required particle size, resulting in poor grinding effects and necessitating repeated grinding cycles. This not only reduces production efficiency but also increases energy consumption and equipment wear. Furthermore, after prolonged operation, grinding and filtering devices may become clogged due to fine particles or fibrous impurities in the pigment slurry, a problem particularly pronounced during the circulating grinding process. Clogging not only reduces filtration efficiency but may also affect the normal operation of the grinding mechanism, leading to a decrease in circulating grinding efficiency.

[0021] Therefore, this application protects a filtration device for pigment production, in which raw materials are guided from the raw material storage box 2 to the inside of the crushing box 3, where the raw materials are crushed and ground into powder by the crushing and grinding mill 6 inside the crushing box 3, and the powder is quantitatively guided to the filter sieve plate 11 on the conveyor table 4. The filter sieve plate 11 is driven by a striking component, which drives the filter sieve plate 11 to rise and fall stably along the lifting limit shaft 12. Combined with the buffering effect of the lifting sleeve spring 13, the filter sieve plate 11 vibrates, which can... The system efficiently sieves the pulverized powder, effectively separating powders that meet the particle size requirements from those that are too large. This allows the filter sieve plate 11 to move stably up and down along multiple lifting limit shafts 12. Simultaneously, the lifting sleeve spring 13 buffers the movement of the filter sieve plate 11. The vibration of the filter sieve plate 11 during its movement vibrates and sieves the powder. Simultaneously, a pair of cleaning screw modules 7 drives the C-shaped guide brackets 8, which in turn drive the scraping brackets 9 to move stably horizontally. The scraping bracket 9 drives multiple scrapers 10 on it to clean the powder on the filter sieve plate 11. Simultaneously, excessively large powders are scraped onto an inclined guide plate, which then guides the powder to the inside of the circulation box. Similarly, the collection box 5 guides the raw material from the holes in the existing filter sieve plate 11. The U-shaped aggregating block 14 collects the powder pulverized inside the pulverizing box 3 onto the filter sieve plate 11. The U-shaped aggregating block 14 effectively gathers the powder pulverized inside the pulverizing box 3. On the filter screen plate 11, the powder is evenly distributed on the screen plate to improve the screening efficiency. Similarly, the funnel-shaped collecting plate 15 at the bottom of the filter screen plate 11 guides the powder to the inside of the collection box 5. For excessively large powder, through the coordinated work of the cleaning screw module 7, the C-shaped guide bracket 8, the scraping bracket 9 and the scraper 10, it can be automatically scraped onto the inclined guide plate and guided into the circulation box. This realizes the automatic circulation of excessively large raw materials back to the crushing process, avoids manual intervention, and improves production efficiency and raw material utilization.

[0022] Furthermore, by sequentially energizing a pair of electromagnets 21, the electromagnets 21 magnetically conduct magnetically to the U-shaped metal rods 19. Multiple conducting metal rods 20 then magnetically attract the striking magnets 18 on the striking convex shafts 17 inside the striking shaft tubes 16. By controlling the magnitude or duration of the energizing current of the electromagnets 21, their magnetic attraction to the striking magnets 18 can be altered, thereby adjusting the striking force of the striking convex shafts 17 on the filter sieve plate 11. This adjustability allows the device to flexibly adjust the striking force according to the characteristics of different pigment raw materials and sieving requirements, ensuring optimal sieving results. After power is cut off, the striking springs 22 drive the striking convex shafts 17, causing them to rise and fall stably along the inner side of the striking shaft tubes 16, thus vibrating and sieving the filter sieve plate 11.

[0023] In summary, in pigment production, the raw material storage box 2 guides the raw material to the crushing box 3 through the feeding flow valve. The crushing and grinding mill 6 in the crushing box 3 crushes and grinds the raw material into powder, and then the powder is quantitatively guided to the filter screen plate 11 on the conveyor table 4. The filter sieve plate 11 vibrates and sieves under the action of the striking assembly. Specifically, a pair of adsorption electromagnets 21 are energized one by one, and the magnetism is conducted to the striking magnet 18 on the striking convex shaft 17 inside the striking shaft tube 16 through the U-shaped metal rod 19 and the conducting metal rod 20. The magnetic adsorption force is changed by controlling the magnitude of the energizing current or the energizing time, thereby adjusting the striking force of the striking convex shaft 17 on the filter sieve plate 11. After the power is turned off, the striking spring 22 drives the striking convex shaft 17 to rise and fall steadily along the inside of the striking shaft tube 16. The striking ball on the striking convex shaft 17 strikes the filter sieve plate 11. At the same time, combined with the buffering effect of the lifting sleeve spring 13, the filter sieve plate 11 vibrates, efficiently sieving the powder and separating the powder that meets the particle size requirements from the excessively large powder. During the screening process, the U-shaped agglomerating block 14 gathers the powder crushed inside the crushing box 3 onto the filter screen plate 11, ensuring uniform powder distribution and improving screening efficiency. Powder meeting the particle size requirements falls through the holes on the filter screen plate 11, and the trumpet-shaped agglomerating plate 15 at the bottom of the filter screen plate 11 guides this part of the powder into the collection box 5. At the same time, a pair of cleaning screw modules 7 operate, and their moving end drives the C-shaped diversion bracket 8, which in turn drives the scraping bracket 9 to operate stably horizontally. Multiple scrapers 10 on the scraping bracket 9 clean the powder on the filter screen plate 11, scraping the excessively large powder onto the inclined diversion plate, which guides this powder into the circulation box. The circulation box is connected to the raw material storage box 2 through a circulation pipe, and the circulation pump on the circulation pipe sends the excessively large powder back to the raw material storage box 2, realizing the automatic circulation of excessively large raw materials back to the crushing process, avoiding manual intervention.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
