Description

Technical Field

[0001] This application relates to the field of pigment dispersion technology, and in particular to a pigment dispersion device for a chromium-free color fingerprint-resistant treatment agent. Background Technology

[0002] Chromium-free color fingerprint-resistant treatment agents are widely used in metal surface treatment fields such as electronics, automobile manufacturing, and building decoration due to their non-toxic and non-polluting properties. These agents not only impart vibrant colors to metal surfaces but also effectively prevent fingerprint residue, improve wear resistance and corrosion resistance, meeting the demands of modern industry for high-quality, high-performance surface treatments.

[0003] In practical use, it has been found that existing dispersion devices lack a complete filtration and circulation mechanism. Insufficiently dispersed pigment particles cannot be separated and reprocessed in a timely manner, easily precipitating in the treatment agent, causing problems such as pipe blockage and nozzle clogging, increasing equipment maintenance costs and downtime. Therefore, we propose a chromium-free color fingerprint-resistant treatment agent pigment dispersion device to solve the above problems. Utility Model Content

[0033] Specifically, the filtration mechanism includes a filter plate 201 and a filter screen 202. The same filter plate 201 is provided on the inner walls of both sides of the filter box 2. The filter plate 201 is located below the feed pipe 301, and the filter screen 202 is provided on the filter plate 201.

[0034] Specifically, the conveying mechanism includes a conveying shaft 303 and a spiral blade 304. The same conveying shaft 303 is rotatably mounted on the inner wall of the top of the top box 4 and the inner wall of the bottom of the conveying cylinder 3. The spiral blade 304 is provided on the conveying shaft 303 and is located above the partition plate 6. A transmission mechanism is provided between the conveying shaft 303 and the stirring shaft 102.

[0035] Specifically, the transmission mechanism includes two transmission wheels 402 and a transmission belt 403. The transmission wheels 402 are fixedly sleeved on both the conveying shaft 303 and the stirring shaft 102. The transmission wheels 402 are located inside the top box 4, and the same transmission belt 403 is sleeved on both transmission wheels 402.

[0036] Specifically, the striking mechanism includes a rotating shaft 5, a rubber rod 501, and a striking seat 502. The rotating shaft 5 is rotatably mounted on the inner wall of the right side of the filter box 2. The right end of the rotating shaft 5 extends into the conveying cylinder 3. The rotating shaft 5 is located below the partition plate 6 and the filter plate 201. The rubber rod 501 is installed on the rotating shaft 5 and is located inside the filter box 2.

[0039] In this application, during operation, the chromium-free color fingerprint-resistant treatment agent pigment is first fed into the mixing chamber 1 through the feed inlet 7. The motor 401 is then started, and its conveyor shaft drives the mixing shaft 102 to rotate the impeller 103 at high speed. This achieves the purpose of breaking down pigment agglomerates through the shearing force and centrifugal force of the impeller 103, completing the initial dispersion to improve the uniformity of the pigment in the treatment agent. The initially dispersed material falls into the filter box 2 through the discharge pipe 101. Under the interception action of the filter plate 201 and the filter screen 202, qualified fine particles are discharged from the discharge pipe 8, while insufficiently dispersed pigment particles remain on the filter screen 202, thus ensuring the dispersion quality of the output material. The guide plate in the filter box 2 guides the insufficiently dispersed pigment particles smoothly through the feed pipe 30. 1. The material enters the conveying cylinder 3 to avoid material retention. At the same time, the motor 401 can drive the conveying shaft 303 and the spiral blade 304 through the transmission wheel 402 and the transmission belt 403 to rotate. The spiral blade 304 can push the unqualified material upwards and send it back to the mixing chamber 1 through the feeding pipe 302 to form a circulating dispersion process, ensuring that the pigment particles are dispersed multiple times. When the conveying shaft 303 rotates, it can drive the rotating shaft 5 to rotate through the bevel gear 503, so that the rubber rod 501 can periodically strike the striking seat 502 at the bottom of the filter plate 201. The resulting vibration can act on the filter screen 202, effectively preventing pigment particles from accumulating and clogging the filter screen, and maintaining the filtration efficiency.
