Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, specifically to an environmentally friendly black slurry storage tank that prevents sedimentation. Background Technology

[0002] Environmentally friendly black paste is a type of black paste produced using recyclable raw materials or low-pollution processes, guided by environmental protection principles. It is widely used in papermaking, textiles, coatings, environmental engineering, and other fields. It is mainly composed of black pigments / dyes (natural sources: such as plant carbon black, humic acid-based black substances; synthetic sources: environmentally friendly carbon black, organic pigments), carriers and auxiliaries (water or bio-based solvents; environmentally friendly additives: such as biodegradable dispersants, formaldehyde-free fixatives, edible preservatives, etc., replacing traditional chemical auxiliaries containing heavy metals or VOCs), and functional fillers (regenerated fibers, slag powder, fly ash, and other industrial wastes) (added in some scenarios).

[0003] After production, environmentally friendly black pulp needs to be stored in storage tanks for subsequent use. However, the internal space of existing storage tanks is relatively simple, which cannot store multiple types of environmentally friendly black pulp from different time periods at the same time, thus limiting the storage effect of the tanks. At the same time, the lack of anti-sedimentation structure means that solid particles (such as fibers and pigments) in the environmentally friendly black pulp will separate from the liquid phase when left to stand for a long time, resulting in a low concentration of the upper layer pulp and an excessively high concentration of the lower layer. This directly affects the stability of subsequent production (such as papermaking and coating preparation), causing uneven paper color, strength fluctuations, or reduced coating adhesion. As a result, the practicality of the tanks is not very good, and there is room for improvement.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, an environmentally friendly black slurry storage tank that prevents sedimentation is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, an environmentally friendly black slurry storage tank for preventing sedimentation according to an embodiment of the present invention includes a tank body 1 and supporting legs 15. Several sets of partition discs 11 are welded inside the tank body 1. A stirring shaft 6 is rotatably and sealingly connected to the center of the surface of each partition disc 11. An air supply disc 12 is sleeved around the outer periphery of the stirring shaft 6, directly above the partition discs 11, and its outer surface is connected to the inner wall of the tank body 1. Several sets of nozzles 13 are mounted around the bottom of the air supply disc 12. Several sets of connecting plates 14 are mounted around the surface of the stirring shaft 6 below the air supply disc 12. A set of nozzles 13 are installed at the bottom of the connecting plates 14. The tank has a scraper 16, the bottom of which contacts the top surface of the partition plate 11. Several sets of stirring blades 7 are mounted around the surface of the stirring shaft 6 above the air supply plate 12. One end of the stirring shaft 6 passes through one side of the tank body 1 and is connected to a motor 5. An air pump 3 is installed on one side of the top of the tank body 1, and the air pump 3 is connected to the air supply plate 12 via an air supply pipe 4. The partition plate 11 is fixed inside the tank body 1 at corresponding positions by welding, dividing the internal space of the tank body 1 into multiple independent chambers. The number and position of the partition plates 11 are rationally arranged inside the tank body 1 according to storage requirements, thereby achieving [specific storage / processing]. Different batches or different compositions of environmentally friendly black slurry are stored in separate chambers; the edge of the partition plate 11 is tightly welded to the inner wall of the tank 1 to form an independent storage space, while the center of the partition plate 11 provides an installation interface for the stirring shaft 6; the main function of the partition plate 11 is to divide the inside of the tank 1 into multiple storage spaces, so that personnel can easily introduce the black slurry into the corresponding chamber through the feed pipe 10 at the designated position according to the batch and composition difference of the environmentally friendly black slurry, thereby realizing separate chamber storage, improving the storage efficiency and practicality of the tank 1, and reducing the financial consumption caused by purchasing multiple sets of tanks 1 for storage; The separator 11 and the tank 1 cooperate to form a multi-cavity storage structure. Together with components such as the feed pipe 10 and discharge pipe 17, it achieves orderly storage and management of environmentally friendly black slurry. A rotary sealing device (a mechanical seal, end-face seal) is located in the middle of the separator 11 surface, specifically composed of the following parts: a rotating ring (installed on the surface of the stirring shaft 6, rotating synchronously with the shaft), a stationary ring (fixed in the center hole of the separator 11, forming a sealing surface with the rotating ring), an elastic element (usually a spring, providing axial pressure to ensure tight contact between the rotating and stationary rings), and an auxiliary sealing ring (such as an O-ring). A rotating ring is used to seal the gap between the stationary ring and the separator 11 to prevent media leakage. When the stirring shaft 6 rotates, the end faces of the rotating ring and the stationary ring form a friction pair, which are kept in contact by spring force and media pressure to prevent the environmentally friendly black slurry from leaking along the shaft. This sealing method is suitable for medium and high speed rotating equipment and can withstand certain pressure and temperature fluctuations. The stirring shaft 6 is connected to the separator 11 through this rotating sealing device, which can ensure the free rotation of the stirring shaft 6 and prevent the environmentally friendly black slurry from leaking from the connection point.The stirring shaft 6 passes through the center of the separator 11 and is connected to the separator 11 via a rotating sealing device, ensuring that the stirring shaft 6 can stir the environmentally friendly black slurry in each chamber during rotation. The axis of the stirring shaft 6 coincides with the central axis of the separator 11. The rotating sealing device provides support and sealing for the stirring shaft 6, enabling it to rotate stably while preventing black slurry leakage. The stirring shaft 6 is the core component of the stirring system. By rotating, it drives the stirring blades 7, connecting plate 14, and scraper 16 to move, achieving the functions of stirring, scraping, and preventing sedimentation of the environmentally friendly black slurry. The stirring shaft 6 is connected to the separator 11 via a rotating seal and rotates under the drive of the motor 5, driving the relevant components to stir the environmentally friendly black slurry in each chamber. The black slurry is processed and, in conjunction with the compartmentalized storage function of the partition plate 11, achieves multi-chamber anti-sedimentation storage. The connecting plate 14 is mounted around the surface of the stirring shaft 6, located below the air supply plate 12, and is fixedly connected to the stirring shaft 6 by welding or bolting (the various connection methods proposed in this application can be selected by personnel during production, and are only for reference and will not be elaborated further). The scraper 16 is installed at the bottom of the connecting plate 14 and is fixedly connected to the connecting plate 14 by bolts or clips, and the bottom of the scraper 16 is in contact with the top surface of the partition plate 11. The connecting plate 14 and the scraper 16 are mounted on the stirring shaft 6, located below the air supply plate 12, and when the stirring shaft 6 rotates... During operation, the connecting plate 14 and scraper 16 rotate accordingly. The scraper 16 contacts the surface of the separator 11, thereby scraping away the sediment on the surface of the separator 11. The number and position of the connecting plates 14 are reasonably set according to the size of the separator 11 and the rotation speed of the stirring shaft 6 to ensure that the scraper 16 is evenly distributed above the separator 11 and maintains good contact with the surface of the separator 11, achieving comprehensive scraping of the surface of the separator 11. The main function of the scraper 16 is to rotate together with the connecting plate 14 when the stirring shaft 6 rotates, contact the surface of the separator 11, and scrape away the sediment deposited on the surface of the separator 11, so that it can be remixed with the flow of the environmentally friendly black slurry, preventing the sediment from accumulating on the surface of the separator 11. The connecting plate 14 and scraper 16 cooperate with the stirring shaft 6 and rotate under the drive of the motor 5. They work together with the stirring action of the stirring blade 7 and the airflow impact of the nozzle 13 to form a multi-effect anti-settling effect of mechanical scraping, stirring and pneumatic impact, which effectively improves the efficiency and effect of anti-settling. The stirring blade 7 is installed around the surface of the stirring shaft 6 and is located above the air supply plate 12. It is fixedly connected to the stirring shaft 6 by welding or bolting to ensure that the stirring blade 7 can rotate with the stirring shaft 6. The stirring blade 7 is set on the surface of the stirring shaft 6 above the air supply plate 12 and can stir the environmentally friendly black slurry above the air supply plate 12 when the stirring shaft 6 rotates, preventing the black slurry from stratifying and settling in this area.The number, shape, and angle of the stirring blades 7 are rationally designed based on the size of the tank 1 and the characteristics of the environmentally friendly black slurry, ensuring that the stirring blades 7 can produce a good stirring effect when rotating, so that the environmentally friendly black slurry presents a uniform flow state. The main function of the stirring blades 7 is to continuously stir the environmentally friendly black slurry above the air supply plate 12 when the stirring shaft 6 rotates, so that the solid particles and liquid phase in the black slurry are fully mixed, avoiding stratification and sedimentation caused by long-term standing, and ensuring the uniformity of the environmentally friendly black slurry. The stirring blades 7 cooperate with the stirring shaft 6 and rotate under the drive of the motor 5. They work together with the air supply plate 12, nozzle 13, connecting plate 14, and scraper 16 to form a multi-layer anti-sedimentation system from top to bottom, comprehensively protecting the environmentally friendly black slurry. To ensure the stability of the black slurry during storage, one end of the stirring shaft 6 passes through one side of the tank body 1 and is fixedly connected to the output shaft of the motor 5 via a coupling, realizing the power transmission between the motor 5 and the stirring shaft 6. The motor 5 is installed on one side of the tank body 1 and connected to the stirring shaft 6 via a coupling, providing rotational power to the stirring shaft 6. The installation position and direction of the motor 5 should ensure smooth and stable power transmission. The coupling is a key component connecting the motor 5 and the stirring shaft 6, which can compensate for the coaxiality error between the motor 5 and the stirring shaft 6, ensuring the reliability of power transmission. At the same time, the coupling also has a certain buffering and vibration reduction effect, reducing the impact on the stirring shaft 6 when the motor 5 starts and stops. The motor 5 is the power source of the entire stirring system. The rotation of the output shaft drives the stirring shaft 6 to rotate, which in turn drives the stirring blades 7, connecting plate 14, and scraper 16 to move, thus achieving the stirring and scraping effect on the environmentally friendly black slurry. The motor 5 is connected to the stirring shaft 6 through a coupling, providing stable power to the stirring shaft 6. Working in conjunction with components such as the air pump 3, it achieves intermittent stirring and pneumatic anti-sedimentation operation, ensuring that the environmentally friendly black slurry remains in a uniformly mixed state during storage. The air pump 3 is installed on one side of the top of the tank 1 and is fixed to the tank 1 by bolts or brackets. One end of the air supply pipe 4 is connected to the air outlet of the air pump 3, and the other end is connected to the air inlet of the air supply plate 12. The connection is sealed by flange or threaded connection to ensure that air can flow smoothly from the air supply pipe 4. Air pump 3 delivers air to air supply plate 12. Air pump 3 is installed on top of tank 1 to facilitate air intake and delivery. The arrangement of air supply pipe 4 should minimize bends and resistance to ensure that air can be delivered to air supply plate 12 quickly and stably. Air pump 3, air supply pipe 4, and air supply plate 12 constitute the airflow channel of the pneumatic anti-sedimentation system. The air supplied by air pump 3 is delivered to the cavity of air supply plate 12 through air supply pipe 4, and then sprayed out through nozzle 13 to form a high-speed airflow. The main function of air pump 3 is to draw in and pressurize external air, and deliver it to air supply plate 12 through air supply pipe 4 to provide air with a certain pressure to nozzle 13, thereby realizing the pneumatic anti-sedimentation function. The function of air supply pipe 4 is to connect air pump 3 and air supply plate 12 to transmit air.The air pump 3 works in conjunction with the air supply pipe 4 and the air supply plate 12. While the motor 5 drives the stirring shaft 6 to rotate and stir the black slurry, the air pump 3 delivers air to the air supply plate 12, which then sprays a high-speed airflow through the nozzle 13. This airflow works in conjunction with the stirring and scraping actions to create multiple anti-sedimentation effects.

[0031] In one embodiment, several sets of feed pipes 10 are obliquely installed on one side surface of the tank body 1 above the partition plate 11. The feed pipes 10 are obliquely installed on one side surface of the tank body 1, above the partition plate 11, and are fixedly connected to the tank body 1 by welding or flange connection. The internal channels of the feed pipes 10 are connected to the corresponding chambers inside the tank body 1. The oblique installation of the feed pipes 10 facilitates the smooth flow of environmentally friendly black slurry from the outside into the chambers inside the tank body 1. The angle of inclination should be reasonably designed according to the flowability of the black slurry and the feeding method to ensure smooth feeding and prevent black slurry residue in the feed pipes 10. The number of feed pipes 10 corresponds to the number of chambers divided by the partition plate 11. Each feed pipe 10 corresponds to one chamber, which makes it convenient for personnel to introduce black slurry into the corresponding chamber through the designated feed pipe 10 according to the batch and composition differences of the black slurry. The main function of the feed pipe 10 is to provide a channel for the environmentally friendly black slurry to enter the internal chamber of the tank 1, realize the chambered feeding, and facilitate the storage and management of black slurry of different batches or different compositions. The feed pipe 10, the tank 1, and the partition plate 11 cooperate with each other to form a chambered feeding system.

[0032] In one embodiment, a discharge pipe 17 is installed at an angle on the other side surface of the tank body 1, flush with the top of the separator 11. The discharge pipe 17 is fixedly connected to the tank body 1 by welding or flange connection. The internal channel of the discharge pipe 17 communicates with the corresponding chamber inside the tank body 1. The flush installation of the discharge pipe 17 with the top of the separator 11 facilitates the smooth discharge of environmentally friendly black slurry from the chamber above the separator 11. The angle of inclination should ensure smooth discharge while preventing the formation of black slurry. The slurry remains in the discharge pipe 17; the position of the discharge pipe 17 corresponds to the feed pipe 10, and each discharge pipe 17 corresponds to a chamber, which facilitates the discharge of the black slurry in the corresponding chamber as needed; the main function of the discharge pipe 17 is to provide a channel for the environmentally friendly black slurry to be discharged from the tank 1, realize the separate discharge of the chamber, and facilitate the use and management of the black slurry in different chambers; the discharge pipe 17 cooperates with the tank 1 and the partition plate 11 to form a separate discharge system, which works together with the feed pipe 10 and other components to realize the orderly storage and discharge of the environmentally friendly black slurry.

[0033] In one embodiment, several sets of support legs 15 are symmetrically installed on both sides of the bottom of the tank 1. The support legs 15 are symmetrical and fixed to both sides of the bottom of the tank 1 by welding or bolting. The symmetrical installation of the support legs 15 can keep the force on the tank 1 balanced, ensuring that the tank 1 is in a stable state when storing environmentally friendly black slurry and preventing the tank 1 from tilting or tipping over. The top of the support legs 15 is tightly connected to the bottom of the tank 1, forming the support structure system of the tank 1 and providing reliable support for the tank 1. The main function of the support legs 15 is to bear the entire weight of the tank 1 and the environmentally friendly black slurry inside, ensuring that the storage tank can be placed stably on the ground. As the basic support component of the tank 1, the support legs 15 together with the tank 1 form the main frame of the storage tank, providing a stable foundation platform for the installation and operation of other components.

[0034] In one embodiment, a label holder 2 and an observation window 8 are provided on the surface of the tank 1 facing personnel. The label holder 2 is fixed to the surface of the tank 1 by adhesive or bolts; the observation window 8 is fixed to the tank 1 by welding or embedding, ensuring a good seal between the observation window 8 and the tank 1 to prevent black slurry leakage. The label holder 2 and observation window 8 are positioned on the surface of the tank 1 facing personnel, facilitating the operator's viewing and identification of the information and status of the black slurry inside the tank 1. The position of the label holder 2 should facilitate the operator's application and replacement of labels, and the position of the observation window 8 should facilitate the operator's observation of the liquid level and black slurry status inside the tank 1. The label holder 2 and observation window 8 work together to label... The label holder 2 is used to identify information such as batch, composition, and storage time of the black slurry inside the tank 1. The observation window 8, in conjunction with the positioning scale 9, is used to display the liquid level and status of the black slurry inside the tank 1, providing intuitive information for operators. The main function of the label holder 2 is to provide identification for the black slurry inside the tank 1, making it easy for operators to distinguish between different batches or different compositions of black slurry. The main function of the observation window 8 is to allow operators to intuitively view the liquid level and status of the black slurry inside the tank 1, while the positioning scale 9 is used to accurately read the liquid level value, facilitating the management of the black slurry storage volume. The label holder 2 and the observation window 8 work together with the tank 1 to provide operators with a convenient way to view and manage information, improving the ease of use and practicality of the storage tank.

[0035] In one embodiment, a positioning scale 9 is provided on the surface of the observation window 8. The positioning scale 9 is directly engraved or printed on the surface of the observation window 8, forming an integral part with the observation window 8, making it convenient for operators to directly read the liquid level value. The positioning scale 9 is set on the surface of the observation window 8, and the zero position of the scale should correspond to the bottom of the tank 1 or the bottom of the partition plate 11 to ensure the accuracy of the liquid level value.

Together with components such as the label holder 2, they realize comprehensive management of the black slurry information inside the tank 1.

[0036] In one embodiment, several sets of pressure relief valves 18 are installed on the surface of the tank body 1. The pressure relief valves 18 are installed at appropriate positions on the surface of the tank body 1 and are fixedly connected to the tank body 1 via flanges or threaded connections. The internal passages of the pressure relief valves 18 are connected to the interior of the tank body 1, ensuring that the pressure inside the tank body 1 can be released through the pressure relief valves 18. The installation position of the pressure relief valves 18 should be selected in a location on the surface of the tank body 1 that is easy to operate and maintain, and it should be ensured that the discharge direction of the pressure relief valves 18 will not pose a safety hazard to personnel and equipment. The pressure relief valves 18 cooperate with the tank body 1. This constitutes the safety protection system of the storage tank. When the pressure inside the tank 1 exceeds the set value, the pressure relief valve 18 automatically opens to release the pressure inside the tank and ensure the safety of the tank 1. The main function of the pressure relief valve 18 is to automatically release pressure when the pressure inside the tank 1 is too high, preventing the tank 1 from exploding or leaking due to excessive pressure, and ensuring the safe operation of the storage tank. The pressure relief valve 18 works in conjunction with the tank 1 as a safety protection device for the storage tank. Together with other components, it ensures that the storage tank operates under safe conditions and protects the safety of personnel and equipment.

[0037] In one embodiment, the air supply plate 12 has multiple cavities on its surface. The air supply plate 12 is fitted around the outer periphery of the stirring shaft 6, located directly above the separator plate 11. The outer surface of the air supply plate 12 is fixedly connected to the inner wall of the tank 1 by welding or bolting, thus fixing the air supply plate 12 inside the tank 1, while the stirring shaft 6 can rotate freely within the air supply plate 12. Positioning the air supply plate 12 above the separator plate 11 on the outer periphery of the stirring shaft 6 allows the air supply plate 12 to work collaboratively with the stirring shaft 6. While the stirring shaft 6 rotates and stirs the black slurry, the air supply plate 12 can spray airflow through the nozzle 13 to impact the surface of the separator plate 11, achieving an anti-sedimentation function. There is a certain gap between the agitator 6 and the stirring shaft 2 to ensure that the stirring shaft 6 can rotate freely. At the same time, the air supply plate 12 is fixed in the corresponding position by connecting to the inner wall of the tank 1, ensuring that the nozzle 13 is accurately positioned and can effectively impact the surface of the separator plate 11 with airflow. The air supply plate 12 is a key component of the pneumatic anti-sedimentation system. Its surface is provided with multiple cavities to facilitate the flow of environmentally friendly black slurry under impact. Air is sprayed out in the form of high-speed airflow through the nozzle 13 at the bottom to impact the surface of the separator plate 11 and disperse the sediment. The rotation of the stirring shaft 6 drives the stirring blades 7 to stir the black slurry. At the same time, the air pump 3 supplies air to the air supply plate 12 through the air supply pipe 4. The air is contained within the air supply plate 12. The air is stored in the cavity of the separator 11 and sprayed out through the nozzle 13. This works in conjunction with the stirring action of the stirring shaft 6 and the scraping action of the scraper 16 to create a multi-layered anti-sedimentation effect. The nozzle 13 is installed around the bottom of the air supply plate 12 and is fixedly connected to the air supply plate 12 by welding or threaded connection. The internal channel of the nozzle 13 is connected to the cavity of the air supply plate 12, ensuring that air can smoothly enter the nozzle 13 from the cavity of the air supply plate 12 and be sprayed out. The nozzle 13 is arranged around the bottom of the air supply plate 12, enabling the high-speed airflow to evenly impact various areas of the surface of the separator 11, improving the effect of dispersing sediment. The number and position of the nozzles 13 are determined according to the size and shape of the separator 11. The airflow is properly configured to ensure that it covers most of the surface of the separator 11, working in conjunction with the scraping area of ​​the scraper 16 to thoroughly remove the sediment from the surface of the separator 11. The main function of the nozzle 13 is to spray the air in the air supply plate 12 in the form of a high-speed airflow, directly impacting the surface of the separator 11 to disperse the sediment deposited on the surface of the separator 11, allowing it to be remixed into the environmentally friendly black slurry. The nozzle 13 and the air supply plate 12 work together, and under the action of the air pump 3, the air is converted into a high-speed airflow. Together with the stirring action of the stirring blade 7 and the scraping action of the scraper 16, they form a multi-layer anti-sedimentation system, effectively preventing the environmentally friendly black slurry from settling during storage.

[0038] Working Principle: In actual use, the interior of tank 1 is divided into multiple storage spaces by partition plates 11. Personnel can introduce the environmentally friendly black slurry into designated areas via feed pipes 10 according to the different batches and compositions produced, thus achieving compartmentalized storage, improving the practicality of tank 1, reducing the cost of purchasing multiple tanks for storage, and enhancing the effectiveness of tank 1. After the environmentally friendly black slurry is filled, the intermittent operation of motor 5 and air pump 3 drives the stirring shaft 6 to rotate and introduces external air. When the stirring shaft 6 rotates, it drives the surface stirring blades 7 to rotate continuously, thus agitating the internal environmentally friendly black slurry and making it flow, thereby preventing stratification and sedimentation caused by prolonged static standing. Simultaneously, the bottom connecting plate 1... 4 will also drive the scraper 16 at the bottom to rotate. Through the contact between the scraper 16 and the separator 11, the sediment deposited on the surface of the separator 11 can be scraped and mixed into the environmentally friendly black slurry along with the internal liquid flow, further preventing sedimentation. At the same time, the air introduced by the air supply pipe 4 will be sprayed out through the nozzle 13 at the bottom of the air supply plate 12. At this time, the high-speed airflow will directly impact the surface of the separator 11, further dispersing the sediment and allowing it to flow and be remixed into the environmentally friendly black slurry. The tank 1 uses multiple different forms to act on the internal sediment and stored materials, making them active and preventing sedimentation from occurring during stagnation. This ensures the quality of the environmentally friendly black slurry for subsequent use and facilitates better use. The device as a whole has the advantages of multi-chamber storage, multiple anti-sedimentation measures, and strong practicality.
