Description

Technical Field

[0001] This utility model relates to the preparation and mixing technology of antistatic coating liquid, and in particular to a valve corrosion-resistant coating preparation equipment suitable for various media, belonging to the technical field of chemical material mixing equipment. Background Technology

[0002] Valve corrosion-resistant coating preparation equipment is a type of specialized complete set of equipment or single-machine combination system used to prepare corrosion-resistant coatings with chemical inertness and physical barrier function on valve surfaces (including sealing surfaces, flow channels, valve body outer walls and other easily corroded parts).

[0003] Publication number CN223069457U discloses a mixing and stirring device, including a mixing tank for filling materials, a stirring mechanism for stirring materials, and a heating mechanism for heating the mixing tank. The heating mechanism includes a heating box, a coil, a water inlet pipe, a water recovery pipe, and a circulating pump. The heating box is filled with hot water. The coil is spirally wound around the outside of the mixing tank. The lower end of the coil is connected to the heating box through the water inlet pipe, and the upper end of the coil is connected to the heating box through the water recovery pipe. The circulating pump pumps hot water into the lower end of the coil. This mixing and stirring device has advantages such as low energy consumption, sufficient heating of the mixing tank, prevention of local low temperatures due to hot water short circuits in the mixing tank, and avoidance of material solidification and agglomeration.

[0004] The above-mentioned mixing method relies on a single stirring structure to carry out the mixing operation. It lacks a pretreatment and crushing mechanism for solid material agglomerates and can only promote the macroscopic flow of materials, which can easily lead to uneven particle dispersion in the coating preparation solution. In addition, traditional feeding methods often adopt a centralized feeding method, which can easily form local high concentration areas when raw materials come into contact with solvents. Particles quickly aggregate due to van der Waals forces or electrostatic attraction, forming secondary agglomerates, which are difficult to break up with subsequent single stirring. Improvements are needed.

[0005] Therefore, a valve corrosion-resistant coating preparation device suitable for various media is proposed. Utility Model Content

[0006] In view of this, the present invention provides a valve corrosion-resistant coating preparation device suitable for various media, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: A valve corrosion-resistant coating preparation device suitable for multiple media includes a mixing tank, a motor installed below the mixing tank, a rotating shaft rotatably installed inside the mixing tank, a feed cylinder installed through the top of the mixing tank, an annular plate installed on the inner wall of the feed cylinder, a crushing toothed plate installed on the rotating shaft, a material distribution plate installed on the inner wall of the mixing tank, a groove provided on the material distribution plate, an inlet pipe and a discharge pipe connected to the mixing tank respectively, an anchor paddle installed on the rotating shaft, a scraper installed above the anchor paddle, and an ultrasonic vibrating plate installed on the outer wall of the mixing tank.

[0008] More preferably, a gap is provided between the ring plate and the crushing tooth plate, and a grinding groove is provided on the inner wall surface of the ring plate.

[0009] More preferably, the rotating shaft coincides with the central axis of the feed cylinder, and the rotating shaft is installed at the output end of the motor.

[0012] More preferably, the turbine propeller is located above the anchor propeller, and the oblique blade propeller is located above the turbine propeller.

[0013] More preferably, the output end of the delivery pump is connected to the return pipe.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. In this utility model, by setting an annular plate with a grinding groove on the inner side of the feed cylinder and a crushing toothed plate on the rotating shaft to cooperate with each other, the raw material agglomerates are crushed and ground by means of the gap between the two, effectively breaking the initial agglomeration structure. At the same time, the umbrella-shaped material distribution plate and the trough below can make the raw material entering through the feed cylinder evenly dispersed, avoiding new agglomeration caused by excessive local concentration. The ultrasonic vibrating plate on the outer wall of the mixing tank can help to disperse micro-agglomerates, further optimizing the dispersion effect. Moreover, the combination of anchor paddle and scraper can prevent material from depositing on the tank wall and reduce the adhesion and drying of agglomerates on the wall surface.

[0016] II. In this utility model, a circulation system is formed by setting up a material extraction pipe, a conveying pump and a return pipe with inner vanes. Combined with a multi-layered turbine blade, inclined blade blade and anchor blade distributed on the rotating shaft, a multi-dimensional flow field is constructed to enhance the overall mixing uniformity of the material in the tank. This design ensures a stable vertical gradient concentration distribution of the coating liquid, effectively avoids the problems of stratification and local concentration difference, and ensures the antistatic properties and coating uniformity of the substrate obtained in the subsequent coating process.

Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, this utility model embodiment provides a valve corrosion-resistant coating preparation device suitable for various media, including a mixing tank 1, a motor 2 installed below the mixing tank 1, a rotating shaft 3 rotatably installed inside the mixing tank 1, a feed cylinder 4 penetrating above the mixing tank 1, a ring plate 5 installed on the inner wall of the feed cylinder 4, a crushing toothed plate 6 installed on the rotating shaft 3, a material distribution plate 7 installed on the inner wall of the mixing tank 1, a trough 8 provided on the material distribution plate 7, an inlet pipe 9 and a discharge pipe 10 connected to the mixing tank 1 respectively, an anchor paddle 11 installed on the rotating shaft 3, a scraper 12 installed above the anchor paddle 11, and an ultrasonic vibrating plate 13 installed on the outer wall of the mixing tank 1.

[0028] In one embodiment, a gap is provided between the ring plate 5 and the crushing toothed plate 6, and a grinding groove is provided on the inner wall surface of the ring plate 5. Under the interaction of the crushing toothed plate 6 and the inner grinding groove of the ring plate 5, the initial agglomerates in the raw material are crushed and ground.

[0029] In one embodiment, the rotating shaft 3 coincides with the central axis of the feed cylinder 4, and the rotating shaft 3 is installed at the output end of the motor 2. Solid raw materials are fed into the feed cylinder 4, and the crushing toothed plate 6, which rotates synchronously with the rotating shaft 3, cooperates with the inner ring plate 5 of the feed cylinder 4.

[0030] In one embodiment, the feed cylinder 4 is made of polypropylene, and the feed plate 7 is umbrella-shaped. The crushed raw material falls naturally onto the umbrella-shaped feed plate 7, and after being evenly dispersed through the troughs 8 on the feed plate 7, it enters the lower area of ​​the mixing tank 1.

[0031] In one embodiment, a material extraction pipe 14 is connected to the mixing tank 1, and a conveying pump 15 is installed on the material extraction pipe 14. A return pipe 16 is connected to the mixing tank 1, and a vane 17 is installed on the inner wall of the return pipe 16. A turbine-type impeller 18 is installed on the rotating shaft 3, and an inclined blade impeller 19 is also installed on the rotating shaft 3. The inclined blade impeller 19 is located above the turbine-type impeller 18, which pushes the upper material to form an axial flow, promoting the exchange and fusion of the upper and lower materials.

[0032] In one embodiment, the turbine propeller 18 is positioned above the anchor propeller 11, and the inclined blade propeller 19 is positioned above the turbine propeller 18. The turbine propeller 18, positioned above the anchor propeller 11, creates strong shear stirring for the middle layer of material in the tank, enhancing the micro-mixing of the material components.

[0033] In one embodiment, the output end of the delivery pump 15 is connected to the return pipe 16. The delivery pump 15 draws out the material from the bottom of the mixing tank 1 through the extraction pipe 14 and delivers it to the return pipe 16 through the output end of the delivery pump 15. The material interacts with the vanes 17 on the inner wall of the return pipe 16, and the vanes 17 form a secondary agitation on the flowing material.

[0034] In operation, this invention works as follows: After starting the motor 2, the output end of the motor 2 drives the rotating shaft 3 to rotate stably inside the mixing tank 1. The solid raw material of the antistatic coating liquid is fed into the feed cylinder 4. The crushing tooth plate 6, which rotates synchronously with the rotating shaft 3, cooperates with the inner ring plate 5 of the feed cylinder 4. Under the interaction of the crushing tooth plate 6 and the grinding grooves inside the ring plate 5, the initial agglomerates in the raw material are crushed and ground, effectively breaking down the agglomerate structure. The crushed raw material naturally falls to the umbrella-shaped distribution plate 7 and is evenly dispersed through the troughs 8 on the distribution plate 7 before entering the lower area of ​​the mixing tank 1, avoiding the formation of local high-concentration areas due to the concentrated accumulation of raw material. Initiating new agglomeration, the solvent is injected into the mixing tank 1 through the inlet pipe 9. During the rotation of the rotating shaft 3, the anchor paddle 11 rotates synchronously, which initially stirs and mixes the solvent and the dispersed raw materials in the mixing tank 1. The scraper 12 above the anchor paddle 11 rotates synchronously with the rotating shaft 3 and slides closely against the inner wall of the mixing tank 1 to prevent the material from depositing and drying on the tank wall and reduce the adhesion of agglomerates on the wall surface. Throughout the anti-agglomeration process, the ultrasonic vibrating plate 13 on the outer wall of the mixing tank 1 runs continuously, and the high-frequency vibration helps to disperse the micro-agglomerates in the material that have not been completely broken, further optimizing the dispersion effect of the raw materials and laying a uniform foundation for subsequent mixing.

[0035] While the anti-agglomeration operation is being carried out simultaneously, the conveying pump 15 is started. The conveying pump 15 draws the material from the bottom of the mixing tank 1 through the extraction pipe 14 and conveys it to the return pipe 16 through the output end of the conveying pump 15. During the flow of the material in the return pipe 16, it interacts with the vanes 17 on the inner side wall of the return pipe 16. The vanes 17 form a secondary agitation on the flowing material, breaking up the uneven concentration of the material in some areas. Then, the material agitated by the vanes 17 flows back to the mixing tank 1 along the return pipe 16, forming a circulation flow of the material in the tank, avoiding the material from stagnating at the bottom of the tank or in some local areas inside the tank. At the same time, the rotating shaft 3 rotates... The turbine blade 18 and the inclined blade blade 19 rotate synchronously. The turbine blade 18 is located above the anchor blade 11, which forms a strong shearing and stirring effect on the middle layer of material in the tank, and enhances the micro-mixing of the material components. The inclined blade blade 19 is located above the turbine blade 18, which pushes the upper layer of material to form an axial flow, promoting the exchange and fusion of the upper and lower layers of material. The rotation of the multi-layer blades and the material flow of the circulation system work together to build a multi-dimensional flow field in the mixing tank 1, continuously enhancing the overall mixing uniformity of the material in the tank, ensuring the stability of the vertical gradient concentration distribution of each component of the coating liquid, and effectively avoiding the problems of material stratification and local concentration differences.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
