Abstract
Description
Technical Field
[0001] This utility model relates to the field of pigment processing technology, and in particular to a graded filtration device. Background Technology
[0002] Fineness is a direct indicator of the tinting strength, dispersion effect, and storage stability of pigment pastes. Generally, for the same pigment paste, the smaller the particle size, the larger the specific surface area, and therefore the greater the hiding power and the higher the tinting strength. The smaller the fineness, the higher the gloss, and the better the dispersion effect and storage stability. During the production process, pigment pastes need to be filtered using filtration equipment.
[0003] A search revealed an existing patent (publication number: CN219231695U) that discloses "a color paste processing and filtration device, comprising: a filter tank, graded filter screens, a centrifugal shaft, and a centrifugal drive device. The graded filter screens are evenly spaced on the inner diameter surface of the filter tank. The centrifugal shaft is inserted into the core of the filter tank and is permeably fitted into the center of the graded filter screens. Centrifugal fans are evenly spaced on the outer diameter surface of the centrifugal shaft and are fitted into the gaps between the graded filter screens. The filter screens are arranged in stages within the filter tank, with varying pore sizes, thus achieving a graded filtration effect. Simultaneously, the centrifugal shaft inserted into the center of the filter tank drives the color paste within the filter tank to rotate centrifugally, accelerating the movement rate of the color paste and enhancing the filtration effect of the filter screens. Finally, the color paste is extracted from the finest pore layer of the filter screens, achieving the desired filtration effect."
[0004] In the process of developing this application, the inventors discovered the following problems with the prior art: Although the patented technology can drive the pigment paste inside the filter tank to rotate centrifugally through a centrifugal shaft to filter the pigment paste to a certain extent, there is a problem that the centrifugal shaft centrifugally throws the pigment paste to the outer surface of the filter tank, causing the outer side of the filter screen to filter the pigment paste. This may result in excessive accumulation of pigment paste at the edge of the filter screen, thereby reducing the filtration efficiency of the filter screen. Therefore, those skilled in the art have provided a graded filtration device to solve the problems mentioned in the background art. Utility Model Content

After a movable plate is installed inside the material box, it can scrape and clean the pigment paste adhering to the inner surface of the material box under the push of a multi-stage electric telescopic rod. At the same time, it can also play an auxiliary role in conveying the pigment paste. Inside the filter box, a servo motor and a scraper are installed. After the servo motor drives the scraper to scrape the upper surface of the filter plate embedded in the bottom of the filter box, the filtration effect of the filter plate on the pigment paste can be improved.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A graded filtration device includes a housing, a material box embedded in the upper surface of the housing, a multi-stage electric telescopic rod embedded at the midpoint of the upper surface of the material box, a movable plate fixedly attached to the lower surface of the multi-stage electric telescopic rod, and limiting plates fixedly provided on both sides of the upper surface of the movable plate.

A servo motor is embedded at the midpoint of the lower end face of each of the two material distribution plates. A scraper is fixedly provided on the lower end face of the output end of each of the two servo motors. A filter plate is embedded in the bottom surface of each of the two filter boxes.
[0009] Furthermore, the outer surface of the movable plate is in contact with the inner wall of the material box, the two limiting plates respectively move through the midpoint of the upper end of the material box on both sides, and the feeding groove is snapped into the upper part of one side of the material box.
[0010] Furthermore, the output ends of the two servo motors rotate through the midpoint of the lower end face of the two material distribution plates, and the lower end faces of the two scrapers are respectively attached to the upper end face of the two filter plates.
[0011] Furthermore, the two filter boxes are respectively movably embedded in the bottom surface of the two fixed frames, and the two filter boxes movably penetrate the front end face of the outer shell.
[0012] Furthermore, a fixing block is fixedly provided at the midpoint of the upper end of the front face of each of the two filter boxes, and an embedding block is movably embedded inside the upper end of each of the two fixing blocks, and the upper ends of the two embedding blocks are respectively fitted and connected to the front face of the outer shell.

[0015] This utility model has the following beneficial effects:
[0016] 1. The present invention proposes a graded filtration device. After the material box is fixed by bolts on the upper end of the outer shell, the pigment paste can be discharged into the inside of the material box through the embedded feed port, so that the material box can play a certain storage role for the pigment paste. At the same time, a multi-stage electric telescopic rod and a fixed plate are set at the upper end of the inside of the material box. The outer surface of the set movable plate can fit against the inner wall of the material box. When the multi-stage electric telescopic rod drives the movable plate to move up and down, the movable plate can scrape the inner wall of the material box, thereby scraping off the attached pigment paste, so as to better discharge the pigment paste for screening and filtration.
[0017] 2. The graded filtration device proposed in this utility model, after embedding a fixed frame inside the outer shell, allows the filter box to be movably embedded in the front end of the fixed frame, thereby enabling the fixed frame to limit and fix the filter box. Simultaneously, the two filter boxes are vertically stacked, further enhancing their graded filtration function. The apertures of the two filter plates embedded in the bottom surface of the filter box decrease from top to bottom, allowing for better filtration and screening of the pigment paste. A servo motor installed in the filter box drives a fixed scraper to rotate, scraping the upper surface of the filter plates and effectively preventing pigment paste accumulation on the upper surface of the filter plates, thus significantly improving the filtration effect of the filter box on the pigment paste.

[0026] 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.
[0027] Reference Figures 1 to 6 A graded filtration device includes a housing 2, a material box 1 embedded in the upper end face of the housing 2, a multi-stage electric telescopic rod 3 embedded in the midpoint of the upper end face of the material box 1, a movable plate 8 fixedly attached to the lower end face of the multi-stage electric telescopic rod 3, and limiting plates 4 fixedly attached to both sides of the upper end face of the movable plate 8. A feeding groove 10 is provided on one side of the material box 1 near the upper end, and a storage box 7 is embedded in the lower end of the front end face of the housing 2.
[0028] The upper part of the outer shell 2 is embedded with a fixing frame 9. The front face of the two fixing frames 9 is provided with a filter box 5. The upper part of the two filter boxes 5 is fixedly provided with a material distribution plate 11. The midpoint of the lower end face of the two material distribution plates 11 is embedded with a servo motor 12. The lower end face of the output end of the two servo motors 12 is fixedly provided with a scraper 15. The bottom surface of the two filter boxes 5 is embedded with a filter plate 13.
[0029] Specifically, after the material box 1 is snapped onto the upper surface of the outer shell 2, a multi-stage electric telescopic rod 3 can be embedded in the upper surface of the material box 1. After a movable plate 8 is fixedly installed on the lower surface of the multi-stage electric telescopic rod 3, the interior of the material box 1 can be raised and lowered under the push of the multi-stage electric telescopic rod 3, thereby scraping and cleaning the interior of the material box 1. The feed trough 10 embedded on one side of the material box 1 can better discharge the pigment into the interior of the material box 1. Simultaneously, after two fixing frames 9 are embedded and fixed inside the outer shell 2, two filter boxes 5 can be embedded in the two fixing frames 9, thereby better fixing the position of the filter boxes 5. After the lower end of the front face of the outer shell 2 is movably embedded into the storage box 7, the storage box 7 can store and collect the screened and filtered pigment paste. After the distribution plate 11 is installed and fixed inside the filter box 5, the servo motor 12 can be snapped into the lower end face of the distribution plate 11. After the scraper 15 is fixedly set at the output end of the servo motor 12, the servo motor 12 can drive the scraper 15 to rotate. At the same time, the scraper 15 and the upper end face of the filter plate 13 embedded in the bottom surface of the filter box 5 are in contact, so that the scraper 15 can scrape and clean the pigment paste accumulated on the upper end face of the filter plate 13, which can effectively prevent the accumulated pigment paste from clogging the filter plate 13.
[0030] Reference Figure 2 and Figure 4 The outer surface of the movable plate 8 is attached to the inner wall of the material box 1, and the two limiting plates 4 respectively move through the midpoint of the upper end of the material box 1 on both sides. The feeding groove 10 is snapped into the upper part of one side of the material box 1.
[0031] Specifically, after the fixed limiting plate 4 passes through the upper surface of the material box 1, it can assist the movable plate 8 in lifting and lowering when the movable plate 8 moves up and down. After the outer surface of the movable plate 8 is attached to the inner wall of the material box 1, the movable plate 8 can scrape and clean the inner wall of the material box 1. During the lifting and lowering process of the movable plate 8, the pigment paste attached to the inner wall of the material box 1 can be scraped off, so as to better discharge and filter the pigment paste. After the feed trough 10 is snapped into the upper side of the material box 1, the pigment paste can be better discharged into the interior of the material box 1 to clean the material box 1.
[0032] Reference Figure 2 and Figure 5 The output ends of the two servo motors 12 rotate through the midpoint of the lower end face of the two material distribution plates 11, and the lower end faces of the two scrapers 15 are respectively attached to the upper end face of the two filter plates 13.
[0033] Specifically, by rotating the output end of the servo motor 12 through the lower end face of the material distribution plate 11, the scraper 15 of the servo motor 12 can be rotated more effectively. After the lower end face of the scraper 15 is attached to the upper end face of the filter plate 13, the scraper 15 can scrape and clean the upper end face of the filter plate 13, preventing the accumulated pigment from clogging the filter plate 13. At the same time, the two filter plates 13 have different apertures, with the upper filter plate 13 having a larger aperture than the lower filter plate 13. Also, the scraper 15 will not damage the filter plate 13 during rotation.
[0034] Reference Figure 2 and Figure 3 Two filter boxes 5 are movably embedded in the bottom surface of two fixed frames 9, and the two filter boxes 5 movably penetrate the front end face of the outer shell 2.
[0035] Specifically, by embedding the filter box 5 into the inner bottom surface of the fixing block 6, the filter frame can be better installed and fixed. At the same time, by inserting the filter box 5 through the front end of the outer shell 2, the filter box 5 can be easily pulled out from the inside of the outer shell 2 to clean the inside of the filter box 5 and to disassemble and replace the filter plate 13.
[0036] Reference Figure 1 and Figure 6 Each of the two filter boxes 5 has a fixed block 6 at the midpoint of the upper end of the front face. Each of the two fixed blocks 6 has an embedded block 16 that is movably embedded in the upper end of the interior. The upper ends of the two embedded blocks 16 are respectively fitted and connected to the front face of the outer shell 2.
[0037] Specifically, after fixing the fixing block 6 on the front end of the filter box 5, an embedding block 16 can be embedded in the upper part of the inside of the fixing block 6, so that the embedding block 16 can move inside the fixing block 6. At the same time, after the embedding block 16 and the outer shell 2 are fitted and connected, the filter box 5 can be limited, which can effectively prevent the filter box 5 and the fixing frame 9 from separating.
[0038] Reference Figure 6 Springs 17 are fixedly installed on both sides of the lower end face of the two embedded blocks 16, and the lower ends of the four springs 17 are fixedly connected to the two sides of the inner bottom surface of the two fixed blocks 6 respectively.
[0039] Specifically, springs 17 are fixedly installed on both sides of the lower end face of the embedded block 16. After the lower end of the spring 17 is fixedly connected to the inner bottom surface of the fixed block 6, the spring 17 can better push the embedded block 16 and the outer shell 2 to fit together. When the embedded block 16 is pressed to squeeze the spring 17, the embedded block 16 and the outer shell 2 can be separated, and the filter box 5 can be pulled out from the fixed frame 9.
[0040] Reference Figure 5 A mounting plate 14 is fixedly sleeved on the outer surface of the output end of the servo motor 12, and the lower end face of the mounting plate 14 is fixedly mounted on both sides of the upper end face of the scraper 15.
[0041] Specifically, after the mounting plate 14 is fixedly sleeved on the output end of the servo motor 12, the lower end face of the mounting plate 14 and the upper end face of the scraper 15 can be fixedly connected, so that the mounting plate 14 can play an auxiliary role in fixing the scraper 15, and the servo motor 12 can better drive the scraper 15 to rotate.
[0042] Working principle: During use, the operator can embed two filter boxes 5, each with a filter plate 13, into two fixed frames 9. The filter plate 13 with a larger aperture is positioned above the filter plate 13 with a smaller aperture. The embedded block 16 in the fixed block 6 is pushed by the spring 17 and connected to the outer shell 2. The operator can then discharge the color paste into the material box 1 through the feed chute 10. After a certain amount of color paste is added, the two servo motors 12 can be activated by the controller, causing the servo motors 12 to drive the scraper 15 to scrape and clean the upper surface of the filter plate 13. At the same time, the multi-stage electric telescopic rod 3 can be activated by the controller to push the movable plate to assist in conveying the color paste in the material box 1 and scrape the inner wall of the material box 1, thereby effectively improving the filtration effect of the color paste. The storage box 7 embedded in the lower surface of the outer shell 2 stores the filtered color paste.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
