Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically a storage tank for anti-precipitation diol dibenzoate coatings. Background Technology

[0002] Diol dibenzoate coatings are typically stored in large vertical or horizontal tanks after production. These coatings usually contain a certain proportion of solid fillers and pigments, such as titanium dioxide and calcium carbonate. During long-term static storage, due to gravity, the solid particles gradually settle to the bottom of the tank, forming a sediment layer. Severe sedimentation can lead to agglomeration and hardening, causing not only difficulties in discharging and pipe blockage, but also uneven composition in each discharge, seriously affecting the final performance and quality of the coating, such as color, hiding power, and leveling properties.

[0003] In existing technologies, simple top-mounted agitators are typically used for intermittent stirring to prevent sedimentation. However, such agitators have significant drawbacks: firstly, their stirring range is limited, resulting in poor agitation of materials in the tank walls and bottom areas, easily creating "dead zones" for sedimentation in these areas; secondly, conventional blades cannot scrape off viscous materials adhering to the tank walls, which over time form a scale layer that is difficult to remove.

[0004] Therefore, this invention provides a storage tank for anti-settling diol dibenzoate coatings to solve the above problems. Utility Model Content

[0005] This invention provides a storage tank for diol dibenzoate coatings that prevents sedimentation. It aims to solve the problems of limited stirring range, poor material agitation in the tank walls and bottom areas, and the easy formation of sedimentation dead zones in these areas in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a storage tank for anti-settling diol dibenzoate coating, comprising a tank body, the bottom of which is a conical bottom inclined towards the center, a discharge port is provided at the lowest point of the conical bottom, the discharge port is connected to a discharge valve, a feed pipe is provided at the top of the tank body, a sealing sleeve is threadedly connected to the outer wall of the feed pipe, a first wall scraping mechanism is provided inside the tank body, a second wall scraping mechanism is provided inside the conical bottom, the first wall scraping mechanism and the second wall scraping mechanism are connected by the same driving mechanism, and multiple vibration mechanisms are provided outside the driving mechanism; The driving mechanism includes a motor, which is fixedly connected to the top of the tank. The output end of the motor is connected to a first connecting shaft, which is connected to a second connecting shaft via a coupling.

[0007] As a preferred technical solution of this application, the first scraping mechanism includes two connecting rings. The inner walls of the two connecting rings are fixedly connected to the outer wall of the same first connecting shaft. Multiple mounting grooves are provided inside the two connecting rings. The two connecting rings are detachably installed to the same connecting plate through the mounting grooves. A movable plate is slidably connected to the inner wall of the connecting plate. An arc-shaped scraper is fixedly connected to one end of the movable plate. The outer diameter of the arc-shaped scraper is adapted to the inner diameter of the tank. An elastic element is provided inside the connecting plate. The inner wall of the connecting plate is connected to the side of the movable plate through the elastic element.

[0008] As a preferred technical solution of this application, the second wall scraping mechanism includes a plurality of scraper blades, which are fixedly connected to the outer wall of the same second connecting shaft. The sides of the scraper blades are provided with inclined plates, and the inclination angle of the inclined side of the scraper blades is consistent with the inclination angle of the conical bottom.

[0009] As a preferred technical solution of this application, the vibration mechanism includes a cross plate, the inner wall of the cross plate is fixedly connected to the outer wall of the first connecting shaft, and circular channels are provided around the inside of the cross plate. The cross plate is movably connected to the impact ball through the circular channels, and the inner wall of the cross plate is connected to the outer wall of the impact ball by a spring.

[0010] As a preferred technical solution of this application, a bearing seat is fixedly connected to the top of the inner wall of the tank, and a bearing is provided inside the bearing seat. The bearing seat is rotatably connected to the first connecting shaft through the bearing.

[0011] As a preferred technical solution of this application, the tank body is provided with an insulation jacket, the top of the insulation jacket is provided with multiple insulation medium inlets, and the bottom of the insulation jacket is provided with multiple insulation medium outlets.

[0012] This utility model has the following beneficial effects: 1. This anti-settling diol benzoate coating storage tank, through the integration of a first and second wall-scraping mechanism linked to the drive mechanism, achieves synchronous and active scraping of the tank's vertical inner wall and conical bottom inner wall. This effectively eliminates the "dead corners of sedimentation" present in traditional agitators, preventing the deposition and scaling of solid materials on the tank walls and bottom, ensuring the uniformity of material composition and smooth discharge.

[0013] 2. This anti-sedimentation diol dibenzoate coating storage tank features a unique vibration mechanism. As the drive shaft rotates, centrifugal force causes impact balls to periodically strike the circular channel, generating high-frequency, low-amplitude mechanical vibration. This vibration is transmitted throughout the tank, helping to dislodge slightly viscous material adhering to the scraper or tank walls, while simultaneously promoting micro-mixing of the material, further preventing sedimentation and stratification.

Detailed Implementation

[0016] 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.

[0017] Please see Figures 1-4A sedimentation-resistant diol dibenzoate coating storage tank includes a tank body 1. The bottom of the tank body 1 is a conical bottom 2 sloping towards the center. The conical bottom 2 utilizes the natural flow-guiding effect of the inclined walls to allow settling solid particles to automatically slide towards the lowest point under gravity, effectively avoiding the "stagnation zone" commonly found in flat-bottomed tanks. This lays the foundation for smooth and thorough discharge. A discharge port is located at the lowest point of the conical bottom 2, connected to a discharge valve 3, enabling reliable opening and closing of the pipeline and flow regulation. Operation is simple. An inlet pipe 13 is located at the top of the tank body 1. The outer wall of the feed pipe 13 is threaded with a sealing sleeve 14, which ensures the sealing reliability of the connection between the feed pipe 13 and the external conveying pipe. This detachable sealing connection method can effectively prevent material leakage and volatilization during feeding, and also facilitates the quick connection and disassembly of the pipe, improving the convenience of operation and environmental hygiene. The tank body 1 is equipped with a first scraping mechanism 5, and the conical bottom 2 is equipped with a second scraping mechanism 6. The first scraping mechanism 5 and the second scraping mechanism 6 are connected through the same drive mechanism 4. Multiple vibration mechanisms 7 are provided on the outside of the drive mechanism 4. Please see Figure 2 and Figure 3 The drive mechanism 4 includes a motor 41, which is fixedly connected to the top of the tank 1. The output end of the motor 41 is connected to a first connecting shaft 42, which is connected to a second connecting shaft 44 via a coupling 43.

[0018] The first wall scraping mechanism 5 includes two connecting rings 51. The inner walls of the two connecting rings 51 are fixedly connected to the outer wall of the same first connecting shaft 42. Multiple mounting grooves are provided inside the two connecting rings 51. The two connecting rings 51 are detachably installed to the same connecting plate 52 through the mounting grooves. A movable plate 53 is slidably connected to the inner wall of the connecting plate 52. An arc-shaped scraper 54 is fixedly connected to one end of the movable plate 53. The outer diameter of the arc-shaped scraper 54 is adapted to the inner diameter of the tank 1. An elastic element is provided inside the connecting plate 52. The inner wall of the connecting plate 52 is connected to the side of the movable plate 53 through the elastic element. The arc-shaped scraper 54 in the first wall scraping mechanism 5 continuously presses against the inner wall of the tank 1 through the elastic element, which can automatically compensate for the wear of the scraper itself and the possible roundness error of the tank 1, and always maintain a good wall scraping effect, thereby improving the reliability and service life of the equipment.

[0019] The second scraping mechanism 6 includes multiple scrapers 61, which are fixedly connected to the outer wall of the same second connecting shaft 44. The sides of the scrapers 61 are provided with inclined plates, and the inclination angle of the inclined side of the scraper 61 is consistent with the inclination angle of the conical bottom 2. The structure of the conical bottom 2, combined with the scrapers 61 at the bottom, guides and pushes the sediment to gather towards the discharge port, making the discharge more thorough and reducing residue.

[0020] When it is necessary to prevent or disrupt the precipitation of the diol dibenzoate coating in tank 1, the motor 41 of the drive mechanism 4 is activated. The motor 41 drives the first connecting shaft 42 to rotate, and the first connecting shaft 42 drives the second connecting shaft 44 to rotate synchronously through the coupling 43.

[0021] As the first connecting shaft 42 rotates, the two connecting rings 51 fixed to it rotate accordingly, thereby driving multiple arc-shaped scrapers 54 installed through the connecting plate 52 to move in a circular motion along the inner wall of the tank 1. Under the action of the elastic element, the moving plate 53 pushes the arc-shaped scrapers 54 to always keep them in close contact with the inner wall of the tank 1, scraping off the material adhering to the vertical section of the tank wall, effectively preventing scaling on the wall surface. At the same time, multiple scraper blades 61 fixed on the second connecting shaft 44 rotate inside the conical bottom 2. Their inclined plate design is consistent with the inclination angle of the conical bottom 2, which can closely fit the inner surface of the conical bottom 2, continuously scraping up the solid particles that have settled to the bottom of the tank and pushing them towards the central discharge port, mixing with the material scraped down from above, completely solving the problem of sedimentation and clumping at the bottom of the tank.

[0022] Please see Figure 4 The vibration mechanism 7 includes a cross plate 71. The inner wall of the cross plate 71 is fixedly connected to the outer wall of the first connecting shaft 42. Circular channels are provided around the inside of the cross plate 71. The cross plate 71 is movably connected to the impact ball 72 through the circular channels. The inner wall of the cross plate 71 and the outer wall of the impact ball 72 are connected by a spring 73. The vibration generated by the vibration mechanism 7 is transmitted to the inner wall of the tank 1, which can effectively prevent viscous materials from adhering, making it easier for the scraped material to detach and fall into the main material, thus improving the scraping effect. At the same time, the vibration can create micro-disturbances in the liquid, further agitating the scraped sediment particles, keeping them suspended in the liquid, and quickly mixing with the main material, thus avoiding secondary sedimentation of the particles after scraping.

[0023] When the first connecting shaft 42 rotates, the cross plate 71 fixed to it rotates synchronously at high speed. Under the action of centrifugal force, the impact ball 72 in the circular channel inside the cross plate 71 moves outward against the tension of the spring 73. However, due to the constraint of the channel, the impact ball 72 will move in the opposite direction under the action of the restoring force of the spring 73 after reaching a certain position, thus generating periodic, high-frequency impacts on the channel wall. The mechanical vibration generated by this impact is transmitted to the entire material system inside the tank through the cross plate 71 and the first connecting shaft 42.

[0024] Please see Figure 3A bearing seat 9 is fixedly connected to the top of the inner wall of the tank body 1. A bearing 8 is installed inside the bearing seat 9. The bearing seat 9 is rotatably connected to the first connecting shaft 42 through the bearing 8. By setting the bearing seat 9 and the bearing 8, the bearing seat 9 and the bearing 8 can play an auxiliary support role during the rotation of the first connecting shaft 42, ensuring the stability of the rotation of the first connecting shaft 42. At the same time, it can also reduce the friction generated when the first connecting shaft 42 rotates, ensuring the efficiency of the rotation of the first connecting shaft 42 and avoiding the situation of rotation jamming.

[0025] Please see Figure 1 The tank body 1 is equipped with an external heat insulation jacket 10. The top of the heat insulation jacket 10 is provided with multiple heat insulation medium inlets 11, and the bottom of the heat insulation jacket 10 is provided with multiple heat insulation medium outlets 12. The external heat insulation jacket 10 can be filled with hot or cold medium to keep the material inside the tank warm or control the temperature, preventing abnormal viscosity or quality deterioration of the material due to temperature changes. It is especially suitable for storing diol dibenzoate coatings that are sensitive to temperature.

[0026] Throughout the storage process, hot water, hot oil, or cooling medium can be introduced into the insulation jacket 10 through the insulation medium inlet 11 according to the ambient temperature and material characteristics, and flow out from the insulation medium outlet 12 to form a circulation, providing insulation or cooling for the tank 1 and ensuring that the material is at a suitable storage temperature.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
