Description

Technical Field

[0001] This utility model relates to the field of ceramic agent production technology, specifically to an anti-precipitation storage tank for ceramic agent production. Background Technology

[0002] As a metal surface treatment agent, ceramic coating agents are widely used in phosphating replacement processes in industries such as automobiles, home appliances, and machinery manufacturing. Their core components are fluorozirconates, silane coupling agents, and organic polymers, which form a dense protective film on the metal surface through chemical conversion, improving corrosion resistance and coating adhesion. However, ceramic coating agent formulations often contain high-density inorganic salts (such as potassium fluorozirconate), nano-scale dispersed phases, and colloidal substances. These components are prone to sedimentation, stratification, or agglomeration due to gravity during storage, resulting in uneven distribution of active ingredients, which directly affects the performance stability of the treatment solution and the treatment effect on the workpiece.

[0003] Existing ceramic precipitator storage tanks mostly adopt ordinary vertical or horizontal tank designs. The solid particles and liquid components in the ceramic precipitator quickly separate when left to stand, forming a bottom sediment layer and a top clear liquid layer, resulting in large concentration fluctuations when the product is taken out. Therefore, we need to propose a sedimentation-proof storage tank for ceramic precipitator production. Utility Model Content

[0004] The purpose of this invention is to provide an anti-precipitation storage tank for the production of ceramic agents, aiming to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sedimentation-preventing storage tank for producing ceramic precipitants includes a tank body, a feed pipe fixedly connected to the top of the tank body, a conical hopper fixedly connected to the bottom of the tank body, a discharge pipe fixedly connected to the bottom of the conical hopper, an agitation assembly for preventing sedimentation and stratification of the ceramic precipitant inside the tank body, an annular scraper inside the tank body, the outer side of the annular scraper being in contact with the inner wall of the tank body, and a power assembly for moving the annular scraper up and down on the outer wall of the tank body.

[0007] Preferably, the agitation assembly includes a rotating rod, the top end of which is rotatably mounted on the inner top of the tank, and a spiral blade is fixedly connected to the outer wall of the rotating rod. The top end of the rotating rod penetrates the tank and is connected to a first drive motor.

[0008] Preferably, the device further includes several sets of scraper rods, all of which are fixedly connected to the bottom end of the rotating rod, and one side of each set of scraper rods is in contact with the inner wall of the conical bucket.

[0009] Preferably, the power assembly includes a first mounting bracket, which is fixedly mounted on the outer wall of the tank.

A drive block is threadedly connected to the outer wall of the lead screw, and a movable plate is fixedly connected to one side of the drive block.

[0010] Preferably, the device further includes several sets of connecting rods, each set of connecting rods being slidably inserted into the top of the tank, with the top ends of each set of connecting rods being fixedly connected to the bottom of the movable plate, and the bottom ends of each set of connecting rods penetrating the tank and being fixedly connected to the annular scraper.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] A sedimentation-preventing storage tank for ceramic precipitant production includes a tank body 1, which is a vertical cylindrical design. The top of the tank body 1 is fixedly connected to a feed pipe 2, and the bottom of the tank body 1 is fixedly connected to a conical hopper 3. The bottom of the conical hopper 3 is fixedly connected to a discharge pipe 4. Both the feed pipe 2 and the discharge pipe 4 are equipped with pneumatic ball valves to achieve automated control of filling and discharging. The tank body 1 is equipped with an agitator 5 to prevent sedimentation and stratification of the ceramic precipitant inside. Through the agitator 5 inside the tank body 1, the rotating rod 501 drives the spiral blade 502 to rotate, forming a composite flow field of longitudinal and transverse directions during the storage of the ceramic precipitant. This prevents high-density components from accumulating at the bottom of the tank body 1. This design significantly reduces the risk of sedimentation and stratification of the ceramic precipitant due to gravity, ensuring the uniformity of the active ingredients during the storage of the ceramic precipitant.

[0023] The tank 1 is equipped with an annular scraper 6 inside. The outer side of the annular scraper 6 is in contact with the inner wall of the tank 1. The outer wall of the tank 1 is equipped with a power component 7 for moving the annular scraper 6 up and down. Through the synergistic action of the annular scraper 6 and the power component 7, the inner wall of the tank 1 is actively cleaned, avoiding the adhesion of ceramic agent stains to the inner wall of the tank 1, which can greatly improve cleaning efficiency.

[0024] The stirring assembly 5 includes a rotating rod 501, the top of which is rotatably mounted on the inner top of the tank 1. A spiral blade 502 is fixedly connected to the outer wall of the rotating rod 501. The top of the rotating rod 501 passes through the tank 1 and is connected to a first drive motor 503. The pitch of the spiral blade 502 is 1 / 3 to 1 / 2 of the diameter of the tank 1, and the helix angle is 15° to 20°. This design can form a composite flow field of axial flow and radial shear at low speed (5-15 rpm). The first drive motor 503 is equipped with a frequency converter to realize stepless speed adjustment.

[0025] It also includes several sets of scraper rods 504, which are all fixedly connected to the bottom end of the rotating rod 501, and one side of each set of scraper rods 504 is in contact with the inner wall of the conical bucket 3. The scraper rods 504 are made of elastic stainless steel.

[0026] The power assembly 7 includes a first mounting bracket 701, which is fixedly mounted on the outer wall of the tank 1. A lead screw 702 is rotatably mounted on the inner wall of the first mounting bracket 701. The bottom end of the lead screw 702 passes through the first mounting bracket 701 and is connected to a second drive motor 703. A drive block 704 is threadedly connected to the outer wall of the lead screw 702. A movable plate 705 is fixedly connected to one side of the drive block 704. The second drive motor 703 is equipped with an encoder to realize closed-loop position control. A copper nut is embedded in the drive block 704 to cooperate with the lead screw 702.

[0027] It also includes several sets of connecting rods 706, which are slidably inserted into the top of the tank body 1, and the top ends of the several sets of connecting rods 706 are fixedly connected to the bottom of the movable plate 705, and the bottom ends of the several sets of connecting rods 706 penetrate the tank body 1 and are fixedly connected to the annular scraper 6.

[0028] A second mounting bracket 8 is fixedly connected to the outer wall of the tank body 1. A guide rod 9 is fixedly connected to the inner wall of the second mounting bracket 8. A slider 10 is slidably connected to the outer wall of the guide rod 9. One side of the slider 10 is fixedly connected to the movable plate 705. The surface of the guide rod 9 is chrome-plated. The slider 10 is embedded with a linear bearing and slides with the guide rod 9. This double guide structure (lead screw + guide rod) can withstand the weight of the annular scraper 6 and the lateral force during operation, and avoid the lead screw 702 from bending and deforming due to unilateral force. By setting the second mounting bracket 8, the guide rod 9 and the slider 10 together, the movable plate 705 is limited, making its movement process more stable.

[0029] The second drive motor 703 is fixedly installed at the bottom of the first mounting bracket 701. One end of the output shaft of the second drive motor 703 is fixedly connected to the bottom end of the lead screw 702. The first drive motor 503 (model: SEW-EurodriveDRE100M4 / BE11 / TF) is equipped with an encoder interface as standard (an absolute encoder can be selected to realize closed-loop speed control) and supports the Modbus RTU communication protocol, which is convenient for integration with PLC. The second drive motor 703 (model: SGM7J-04A7C61) supports electronic gear ratio setting and is precisely matched with the lead screw, which is suitable for high-frequency and high-reliability wall scraping tasks.

[0030] Both the first drive motor 503 and the second drive motor 703 are equipped with overheat protectors. When the temperature exceeds 85°C, the power is automatically cut off to prevent the motor from burning out. The motor control cabinet integrates a PLC and a touch screen, which can preset the stirring and scraping cycles (such as stirring for 5 minutes every 2 hours and scraping the wall once every 8 hours).

[0031] Working principle: Anti-sedimentation stirring stage: The first drive motor 503 starts, driving the rotating rod 501 to drive the spiral blade 502 to rotate. Under the action of the spiral lift, the ceramic agent flows upward along the axis. After reaching the top of the tank, it turns back downward to form a longitudinal circulation. At the same time, the scraper 504 rotates synchronously with the rotating rod 501 to remove the sediment on the inner wall of the conical hopper 3 and roll it into the main flow field. This process inhibits particle agglomeration through fluid dynamic shear force, ensuring that the components such as fluorozirconate and silane coupling agent in the ceramic agent are evenly distributed.

[0032] Cleaning stage of the inner wall of tank 1: The second drive motor 703 starts, drives the lead screw 702 to rotate, and the drive block 704 moves vertically along the lead screw 702. Through the movable plate 705, the connecting rod 706 and the annular scraper 6 move up and down reciprocally (the stroke range covers the full height of tank 1). The outer elastic rubber layer of the annular scraper 6 is tightly attached to the inner wall of tank 1 to scrape off the attached ceramic agent residue or crystal layer. The cleaned product falls to the bottom of the conical hopper 3 with gravity and is finally discharged through the discharge pipe 4.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
