Description

Technical Field

[0001] This utility model relates to the field of pickling pots, specifically a pickling pot for pigment processing. Background Technology

[0002] Phthalocyanine blue is generally synthesized in α and 0 forms and needs to be pigmented through a series of suitable methods. Common pigmentation methods include acid treatment, grinding, and solvent treatment. The purpose of pigmentation is threefold: first, to transform the crystal form to the stable α form, and sometimes to obtain a product with greater red light; second, to control the particle size distribution and shape; and third, to perform surface treatment to improve dispersibility and applicability in specific application media. Through these adjustments, a product with bright color, high tinting strength, good dispersibility, and high fastness properties such as weather resistance and heat resistance is obtained.

[0003] Pigment pickling is a method of treating pigments to improve their performance, stability, and safety. During the pickling process, steam overflows from the pickling pot. If the ports of the pickling pot are not sealed, the steam will diffuse into the air, polluting the air and affecting air quality. In severe cases, the volatile organic compounds in the steam can irritate the respiratory tract of nearby operators, causing symptoms such as coughing and difficulty breathing, and increasing the risk of respiratory infections. Utility Model Content

In severe cases, the volatile organic compounds in the steam can irritate the respiratory tract of nearby operators, causing symptoms such as coughing and difficulty breathing, and increasing the risk of respiratory infections. This utility model proposes a pickling pot for pigment processing.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an acid washing pot for pigment processing, including an acid washing pot body, a support leg fixedly connected to the bottom of the acid washing pot body, a cover fixedly connected to the top of the acid washing pot body, a stirring motor fixedly connected to one side of the cover, and a filter mechanism provided on one side of the cover.

[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses an acid pickling pot for pigment processing. (See also...)

[0025] The filtration mechanism 5 includes a connecting pipe 501, the surface of which is fixedly connected to the inner cavity of the cover 3. One end of the connecting pipe 501 is fixedly connected to a first conveying pipe 502, and one end of the first conveying pipe 502 is fixedly connected to a filter 503. One side of the filter 503 is fixedly connected to a second conveying pipe 504, and one end of the second conveying pipe 504 is fixedly connected to a vacuum pump 505. The output end of the vacuum pump 505 is fixedly connected to a third conveying pipe 506, and one end of the third conveying pipe 506 is equipped with a condensing mechanism 6. The pickling pot for pigment processing seals the port of the pickling pot body 1 through the cover 3, and the pigment inside the pickling pot body 1 is stirred by the stirring motor 4. The material undergoes acid washing treatment. The filter mechanism 5 is connected to the cover 3 through the connecting pipe 501. The vacuum pump 505 creates a negative pressure at the port of the cover 3 that is connected to the connecting pipe 501, which extracts the steam generated during acid washing. The steam first enters the filter 503 through the first conveying pipe 502. The filter 503 can filter out impurities in the steam. The steam after filtering impurities enters the condensation mechanism 6 through the second conveying pipe 504 and the third conveying pipe 506. After entering the condensation mechanism 6, the steam begins to release heat and gradually loses its gaseous properties, eventually turning into a liquid state so as to recover water resources for reuse. This minimizes steam overflow and achieves energy-saving and environmentally friendly efficiency.

[0026] Reference Figure 2 A first filter screen 7 is fixedly connected to the inner wall of filter 503, and a second filter screen 8 is fixedly connected to the inner wall of filter 503. The pores of the second filter screen 8 are smaller than those of the first filter screen 7. Through the first filter screen 7 and the second filter screen 8, steam enters filter 503 through the first delivery pipe 502. First, it passes through the first filter screen 7 with a larger pore size to perform preliminary filtration of particulate impurities, and then passes through the second filter screen 8 with a smaller pore size to further filter impurities in the steam, thereby improving the filtration effect of particulate impurities in the steam.

[0027] Reference Figure 2 A cylinder 9 is fixedly installed on one side of the filter 503. A scraper 10 is fixedly connected to the output end of the cylinder 9. One side of the scraper 10 is attached to the inner wall of the filter 503. The inner cavity of the scraper 10 is slidably connected to the surface of the first filter screen 7. A material passage trough 11 is opened on the inner wall of the filter 503. A waste storage box 12 is fixedly connected to one side of the filter 503. Through the scraper 10, impurities are filtered for a long time, resulting in impurities remaining on the surfaces of the first filter screen 7 and the second filter screen 8. Scrapers 10 are provided on the surfaces of the first filter screen 7 and the second filter screen 8. The scraper 10 can be scraped off by the corresponding cylinder 9. The scraped impurities are pushed to the material passage trough 11. The waste enters the waste storage box 12 through the material passage 11 for collection and subsequent processing.

[0028] Reference Figure 1 , Figure 3 and Figure 4 The condensing mechanism 6 includes a housing 601, the inner cavity of which is fixedly connected to the surface of the third conveying pipe 506. A water collection tank 602 is fixedly connected to the bottom of the housing 601. A condenser 603 is fixedly installed on the top of the housing 601. A condensing plate 604 is fixedly connected to one side of the condenser 603. There are several condensing plates 604, and the surfaces of all condensing plates 604 are fixedly connected to the inner cavity of the housing 601. A condensing pipe 605 is fixedly connected to the inner cavity of the condensing plate 604. One end of the condensing pipe 605 is connected to one end of the third conveying pipe 506. The condenser 605 is fixedly connected to a nozzle 606 at one end. Through the condensation mechanism 6, the condenser 603 transfers the cooling power to the copper metal condenser plate 604. The condenser 605 is also made of copper metal and is irregularly shaped and connected between several condenser plates 604. The steam that has been cleaned of impurities enters the condenser 605 through the third conveying pipe 506 and releases heat layer by layer until it liquefies to form condensate. The condensate is discharged through the nozzle 606 to the water collection tank 602 for centralized collection so as to recycle water resources for reuse.

[0029] Reference Figure 4 The inner wall of the housing 601 is fixedly connected to a polyester fiber filter plate 607, a polypropylene filter plate 608, and an activated carbon filter plate 609. The polyester fiber filter plate 607 and the polypropylene filter plate 608 can filter out residual acid and corrosive organic matter in the condensate. The activated carbon filter plate 609 further filters out microorganisms and odors in the condensate, ensuring the purity of the condensate.

[0030] Reference Figure 4 The bottom of the water collection tank 602 is fixedly connected to a drain pipe 610. A water pump 611 is fixedly installed at one end of the drain pipe 610. The output end of the water pump 611 is fixedly connected to a return water pipe 612. A control valve 613 is fixedly connected to the surface of the return water pipe 612. One end of the return water pipe 612 is fixedly connected to the bottom of the pickling pot body 1. When the pickling pot body 1 is processing pigments again, the control valve 613 can be opened through the return water pipe 612 to connect the water collection tank 602 and the pickling pot body 1. The pure condensate stored in the water collection tank 602 is then pumped through the return water pipe 612 to the inner cavity of the pickling pot body 1 by the water pump 611, thereby improving the efficiency of resource utilization.

[0031] Working principle: The cap 3 seals the port of the pickling pot body 1. The pigment inside the pickling pot body 1 is pickled by the stirring motor 4. The filter mechanism 5 is connected to the cap 3 through the connecting pipe 501. The vacuum pump 505 creates a negative pressure inside the cap 3 and the port connected to the connecting pipe 501, extracting the steam generated during pickling. The steam first enters the filter 503 through the first conveying pipe 502. It first passes through the first filter screen 7 with a larger pore size for preliminary filtration of particulate impurities, and then passes through the second filter screen 8 with a smaller pore size for further filtration of impurities in the steam, thereby improving the filtration effect of particulate impurities in the steam. The steam after impurity filtration enters the condensing mechanism 6 through the second conveying pipe 504 and the third conveying pipe 506. The condenser 603 transfers the cooling to the copper metal condensing plate 604. The condensing pipe 605 is also made of copper metal and condenses... Pipe 605 is irregularly shaped and tortuously connected between several condensing plates 604. The steam that has been cleaned of impurities enters the condensing pipe 605 through the third conveying pipe 506 and releases heat layer by layer until it liquefies to form condensate. The condensate is discharged through the nozzle 606 to the water collection tank 602 for centralized collection so as to recycle water resources for reuse. Both the polyester fiber filter plate 607 and the polypropylene filter plate 608 can filter the residual acid and corrosive organic matter in the condensate. The activated carbon filter plate 609 further filters the microorganisms and odors in the condensate to ensure the purity of the condensate. When the pickling pot body 1 is used for pigment processing again, the control valve 613 can be opened to connect the water collection tank 602 and the pickling pot body 1. The pure condensate stored in the water collection tank 602 is pumped through the return water pipe 612 to the inner cavity of the pickling pot body 1 by the water pump 611, thereby improving the efficiency of resource utilization.
