Description

Technical Field

[0001] This utility model relates to the field of pigment production technology, and more specifically, to a washing device for producing ultrafine pearlescent pigments. Background Technology

[0002] In the industrial production process of ultrafine pearlescent pigments, the washing and filtration stages are core process steps that determine product purity, particle size distribution, and overall performance. Currently, most commercially available washing equipment suffers from insufficient mixing and dispersion efficiency. Traditional stirring structures often employ a single-blade design, resulting in limited turbulence intensity between the material and washing water. This leads to pigment particles easily forming agglomerates, making it difficult to achieve uniform dispersion at the micron scale, directly impacting subsequent washing efficiency and impurity removal. Simultaneously, the conventional cylindrical container has a flat bottom, making material prone to accumulation. Furthermore, the large distance between the stirring blades and the container wall prevents effective removal of material adhering to the inner wall, resulting in raw material waste and potential product inconsistency due to material deterioration. In addition, existing filtration devices often use single-layer filters, which cannot meet the multi-particle-size grading requirements of ultrafine pearlescent pigments. Filter clogging necessitates machine shutdown for disassembly and cleaning, causing production interruptions and high manual maintenance costs. Fixed washing tanks prevent rapid switching between filtration and washing stations, requiring waiting for each batch to complete before proceeding to the next, thus hindering the automation and large-scale operation efficiency of the production line. The aforementioned technical issues make it difficult for traditional equipment to meet the demands of modern ultrafine pearlescent pigment production for high-precision dispersion, efficient filtration, and continuous operation. There is an urgent need to improve the process adaptability and production efficiency of equipment through structural innovation. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. 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.

[0027] Please see Figures 1-4 This utility model provides a technical solution: a washing device for producing ultrafine pearlescent pigments, including a base plate 110, a bracket 111 symmetrically fixedly installed at the top of the base plate 110, a barrel 120 fixedly installed at the top of the bracket 111, a feed hopper 121 and a first water inlet pipe 122 provided at the top of the barrel 120, and a stirring assembly installed inside the barrel 120, a discharge pipe 123 installed at the bottom of the barrel 120, a solenoid valve installed on the discharge pipe 123, a support platform 130 slidably installed at the top of the base plate 110, a washing tank symmetrically arranged at the top of the support platform 130, a filter basket 140 installed inside the washing tank, a filter assembly installed inside the filter basket 140, water outlet holes provided on both sides of the washing tank, a rinsing assembly installed at the bottom of the barrel 120, and a driving assembly installed on the support platform 130.

[0028] In some specific implementations, the bottom of the barrel 120 is tapered, and the barrel 120 is located at the center above the base plate 110. The tapered bottom design guides the material inside the barrel to flow towards the discharge pipe 123, avoiding material stagnation and accumulation, and improving unloading efficiency.

[0029] Please see Figure 2 The mixing assembly includes a first motor 150, a rotating shaft 151, and mixing rods 152. The rotating shaft 151 is rotatably mounted on the top of the inner wall of the tank 120. The first motor 150 is mounted on the top of the rotating shaft 151. Multiple mixing rods 152 are fixedly mounted on the outside of the rotating shaft 151. The first motor 150 is fixedly mounted on the top of the tank 120, and its output end passes through the top of the tank 120 and is fixedly connected to the top of the rotating shaft 151. The multiple mixing rods 152 are equidistantly mounted in a ring on the rotating shaft 151. The equidistantly distributed mixing rods 152 can generate a uniform turbulent effect, promoting thorough mixing of pigments and cleaning water, avoiding local agglomeration, and improving the cleaning effect.

[0030] In some specific implementations, a support plate 153 is fixedly mounted on the rotating shaft 151, and the top of the support plate 153 is rotatably connected to the top of the inner wall of the barrel 120. The support plate 153 provides an additional top support point for the rotating shaft 151, enhancing the stability of the rotating shaft 151 during high-speed rotation, reducing the risk of the stirring rod 152 colliding with the barrel wall due to shaking, and extending the service life of the equipment.

[0031] In some specific implementations, multiple mixing rods 154 are fixedly installed on the stirring rod 152. The mixing rods 154 are arranged perpendicular to the stirring rod 152, and the mixing rods 154 on adjacent stirring rods 152 are staggered to further improve the uniformity of dispersion.

[0032] In some specific implementations, a scraper 155 is fixedly installed at one end of the stirring rod 152, and the scraper 155 is in close contact with the inner wall of the barrel 120. As the scraper 155 rotates with the stirring rod 152, it can continuously scrape off the material adhering to the inner wall of the barrel 120, avoiding material residue and deterioration that could affect product purity, while also reducing the frequency of manual cleaning and improving production efficiency.

[0033] Please see Figure 3The rinsing assembly includes an annular pipe 160, a second water inlet pipe 161, and nozzles 162. The annular pipe 160 is fixedly installed at the bottom of the barrel 120 via a support rod. The second water inlet pipe 161 is fixedly installed on the outside of the annular pipe 160. One end of the second water inlet pipe 161 passes through the bracket 111 and is connected to a water source. Multiple nozzles 162 are fixedly installed at the bottom of the annular pipe 160. The annular pipe 160 is sleeved on the outside of the discharge pipe 123. The annular pipe 160 is arranged around the discharge pipe 123, so that the nozzles 162 can form a 360° annular rinsing area for the falling material, ensuring that pigment particles come into contact with the water flow from all directions and effectively removing surface impurities. The design of the water flow and material falling synchronously can complete the rinsing simultaneously during the unloading process, shortening the process time.

[0034] Please see Figure 4 and Figure 5 The drive assembly includes a side plate 170, a threaded rod 171, and a guide rod 172. The side plates 170 are symmetrically fixedly installed on both sides of the top of the base plate 110. The threaded rod 171 is rotatably installed between the two side plates 170, and the guide rod 172 is fixedly installed between them. Support plates 173 are fixedly installed on both sides of the support platform 130. The two support plates 173 are threaded onto the threaded rod 171 and slidably installed onto the guide rod 172, respectively. A second motor 174 is installed at one end of the threaded rod 171 and is fixedly installed on one side of the side plate 170. The output end of the second motor 174 passes through the side plate 170 and is fixedly connected to one end of the threaded rod 171. This allows for switching between the positions of the two cleaning tanks, facilitating alternating filtration and cleaning operations and reducing downtime. The reciprocating movement function uses mechanical force to vibrate the filter basket 140, preventing the filter plate 142 from clogging and improving filtration efficiency.

[0035] In some specific implementations, the filter basket 140 is a mesh structure, with a support frame 141 fixedly installed at the top of the filter basket 140, and handles symmetrically fixedly installed on the outer side of the support frame 141. The mesh filter basket 140 can quickly achieve solid-liquid separation, and together with the internal filtration components, it improves the grading effect; the support frame 141 enhances the structural strength of the filter basket 140, and the handle design facilitates quick manual removal of the filter basket 140 for replacing filter cakes or cleaning components, reducing the difficulty of operation.

[0036] In some specific implementations, the filter assembly includes multiple filter plates 142, with adjacent filter plates 142 fixedly connected by a round rod 143. The filter holes on the filter plates 142 decrease in size from top to bottom, and the filter plates 142 are slidably connected to the inner wall of the filter basket 140. The multi-layer decreasing filter hole design allows for gradient classification of ultrafine pearlescent pigments, with large particles retained in the upper filter plate 142 and fine particles passing through the lower filter holes, achieving precise particle size control. The fixing structure of the round rod 143 allows the filter plates 142 to be pulled out as a whole, facilitating quick replacement of filter assemblies with different pore sizes and adapting to diverse production needs.

[0037] Working principle: Ultrafine pearlescent pigment raw materials are fed into the barrel 120 through the feed hopper 121, while cleaning water is injected through the first water inlet pipe 122. The first motor 150 starts, driving the rotating shaft 151 to rotate, which in turn drives the stirring rod 152 and mixing rod 154 fixed on its outer side to rotate. The stirring rod 152 is distributed in a ring at equal intervals, working in conjunction with the vertically staggered mixing rod 154 to achieve thorough mixing of pigment and water, avoiding local agglomeration. The scraper 155 adheres to the inner wall of the barrel 120 and rotates synchronously with the stirring to prevent material from adhering to the barrel wall and ensure uniform mixing.

[0038] After mixing, the solenoid valve on the discharge pipe 123 is opened, and the material flows through the bottom of the conical barrel into the filter basket 140 below. An annular pipe 160 is fitted over the discharge pipe 123 and connected to a water source via a second water inlet pipe 161. Water flows downwards through nozzles 162, which are evenly distributed at the bottom of the annular pipe, rinsing the material during the discharge process, further dispersing pigment particles, and cleaning away surface impurities. The rinsed wastewater is discharged through the outlet holes on both sides of the cleaning tank, achieving solid-liquid separation.

[0039] The filter basket 140 has a mesh structure and houses a filter assembly, including multiple filter plates 142 with decreasing pore size from top to bottom. When material passes through the filter plates, pigment particles of different sizes are sequentially screened; finer particles pass through the lower filter pores, while coarser particles remain in the upper layer, achieving graded filtration. A support frame 141 is fixed to the top of the filter basket and has a handle on the outside for easy manual removal and replacement of the filter basket.

[0040] The second motor 174 starts, driving the threaded rod 171 to rotate. Through the threaded engagement, the support plate 173 slides along the guide rod 172, thereby pushing the support platform 130 to move horizontally on the base plate 110. The movement of the support platform can switch the positions of the two cleaning tanks, facilitating alternating filtration and cleaning operations, improving production efficiency. At the same time, it can drive the support platform 130 to move back and forth to prevent the filter plate from clogging.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
