Abstract
Description
Technical Field
[0001] This utility model relates to the field of zinc plating additive production technology, and in particular to a reaction vessel for zinc plating additives. Background Technology
[0002] Zinc plating is a corrosion prevention method that forms a protective zinc layer on the metal surface to prevent corrosion. In the preparation of zinc plating additives, a reaction vessel can be used for reaction and mixing.
[0003] The preparation of galvanizing additives requires the use of a reaction vessel. During the production of galvanizing additives, different powders need to be added to the reaction vessel. Traditional reaction vessels have a single stirring method, and some powders are prone to clumping after being placed. They are not easy to dissolve during the feeding and stirring process and tend to accumulate at the bottom or on the wall of the processing tank. This causes the stirring rod to fail to effectively agitate the accumulated raw materials, resulting in uneven stirring and affecting production efficiency and processing quality. Utility Model Content
[0004] To address the aforementioned technical problems, this invention provides a reaction vessel for zinc plating additives.
[0005] The technical solution of this utility model is achieved through the following scheme: a reaction vessel for galvanizing additives, comprising a supporting outer cylinder, a grinding feed cylinder, and a stirring inner cylinder, wherein the supporting outer cylinder covers the stirring inner cylinder, a heating zone is provided between the supporting outer cylinder and the stirring inner cylinder, the grinding feed cylinder is flanged and connected to the stirring inner cylinder, the grinding feed cylinder is connected to the supporting outer cylinder through a support block, a support platform is provided on the top surface of the supporting outer cylinder, the grinding feed cylinder passes through the supporting outer cylinder and the support platform, a first drive motor is provided on the top surface of the grinding feed cylinder, a rotating shaft is rotatably mounted on the drive end of the first drive motor, and the rotating shaft passes through the grinding feed cylinder and the stirring inner cylinder.
[0006] Through the above technical solutions, the grinding feed cylinder grinds the powder before it enters the mixing inner cylinder, breaking up any lumps in the powder. This makes it easier to dissolve during the feeding and mixing process, reducing the possibility of powder accumulating at the bottom or wall of the processing tank, achieving uniform mixing, and improving mixing efficiency. The heating zone provides the necessary temperature control for the reactor. The grinding feed cylinder is connected to the outer support cylinder via a support block and to the flange of the mixing inner cylinder, enhancing the structural stability of the entire grinding feed cylinder, reducing vibration or shaking during operation, and ensuring stable operation of the equipment.
[0007] Preferably, the grinding feed cylinder includes a feed cylinder, a feeding crushing device, a grinding block, and a grinding seat. The feeding crushing device is installed on the feed cylinder and is connected to the inner cavity of the feed cylinder. A grinding seat is provided on the side wall of the inner cavity of the feed cylinder. The grinding seat is adapted to the grinding block, and the grinding block is rotatably installed in the feed cylinder via a rotating shaft.
[0008] Preferably, the feeding and crushing device includes a feeding hopper and crushing rollers. The feeding hopper is mounted on a support platform, and a plurality of crushing rollers are installed inside the feeding hopper. A feeding ramp is provided inside the feeding hopper.
[0009] The above technical solution uses crushing rollers to initially crush the powder entering the reactor, and then uses subsequent grinding blocks to further refine the powder particles, ensuring that the powder reaches the required fineness before entering the mixing cylinder, thus reducing uneven mixing in the later stages. The feed hopper is equipped with a feed ramp, which helps the powder slide smoothly into the crushing range of the crushing rollers, reducing the accumulation and blockage of powder in the feed hopper.
[0010] Preferably, the mixing inner cylinder includes a mixing inner cylinder, mixing rollers and scrapers, and several of the mixing rollers and scrapers are rotatably installed in the mixing inner cylinder via a rotating shaft, with the scrapers abutting against the bottom surface of the inner cavity of the mixing cylinder.
[0011] Preferably, the bottom surface of the mixing inner cylinder has several liquid outlet holes, which are connected to the discharge box, and the discharge box is connected to the liquid outlet pipe.
[0012] Preferably, the discharge box is equipped with a discharge ramp and a mixing fan.
[0013] Preferably, the heating zone is equipped with several heaters, and the outer support cylinder is equipped with a temperature sensor.
[0014] Through the above technical solutions, the mixing process is made more efficient by using stirring rollers and scrapers. The scrapers not only prevent material accumulation, but also assist in pushing the mixture during discharge. Together with the mixing fan, the mixture can flow out smoothly, reducing material residue in the mixing cylinder and discharge box, and improving discharge and mixing efficiency. The heater and temperature sensor achieve precise temperature control, ensuring that the galvanizing additive is prepared under the optimal temperature conditions, thereby improving product quality.
[0015] In summary, this utility model has the following beneficial effects:
[0016] 1. This utility model uses a grinding feed cylinder to grind the powder before it enters the mixing inner cylinder, breaking up any lumps in the powder.

The grinding feed cylinder is connected to the outer support cylinder via a support block and to the flange of the mixing inner cylinder, enhancing the structural stability of the entire grinding feed cylinder, reducing vibration or shaking during operation, and ensuring stable operation of the equipment.
[0017] 2. The powder entering the reactor is initially crushed by the crushing roller, and then further refined by the subsequent grinding blocks and grinding seats to ensure that the powder reaches the required fineness before entering the mixing cylinder, thereby reducing uneven mixing in the later stage. The feed hopper is equipped with a feed ramp to help the powder slide smoothly into the crushing range of the crushing roller, reducing the accumulation and blockage of powder in the feed hopper.
[0018] 3. The mixing process is made more efficient by using a stirring roller and a scraper. The scraper not only prevents material accumulation, but also helps to push the mixture during discharge.

[0028] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.
[0030] A reaction vessel with a zinc plating additive, such as Figures 1-6 As shown, the system includes a supporting outer cylinder 1, a grinding feed cylinder 2, and a stirring inner cylinder 3. The supporting outer cylinder 1 covers the stirring inner cylinder 3, and a heating zone 5 is provided between the supporting outer cylinder 1 and the stirring inner cylinder 3. The grinding feed cylinder 2 is flanged to the stirring inner cylinder 3, and the grinding feed cylinder 2 is connected to the supporting outer cylinder 1 through a support block 6. A support platform 8 is provided on the top surface of the supporting outer cylinder 1. The grinding feed cylinder 2 passes through the supporting outer cylinder 1 and the support platform 8. A first drive motor 7 is provided on the top surface of the grinding feed cylinder 2. A rotating shaft is rotatably mounted on the drive end of the first drive motor 7. The rotating shaft passes through the grinding feed cylinder 2 and the stirring inner cylinder 3. The inner cavity of the grinding feed cylinder 2 is connected to the stirring inner cylinder 3, and its bottom side is tightly sealed to the stirring inner cylinder 3. The flange is sealed, and a support block 6 is screwed to the outer side of the flange. It is fixed to the outer support cylinder 1 and works with the support platform 8 to completely restrict the position of the outer support cylinder 1, ensuring stability during the grinding process and reducing the risk of uneven grinding or equipment damage caused by vibration or shaking. The first drive motor 7 is preferably a geared motor to provide more stable torque output. A heating circulation pipe 103 is connected to the outer support cylinder 1 to introduce a heating medium, such as oil or steam. A discharge box 4 is set at the bottom of the stirring inner cylinder 3. The discharge box 4 is an integral structure with the stirring inner cylinder 3. The discharge box 4 is connected to the liquid outlet pipe 100, and the stirring inner cylinder 3 is connected to the water inlet pipe 101.
[0031] like Figure 3 As shown, grinding blocks 23, several stirring rollers 32 and scrapers 33 are installed on the rotating shaft from top to bottom.
[0032] like Figure 3 and Figure 5As shown, the feed cylinder 21 includes a feed cylinder 21, a feed crushing device 22, grinding blocks 23, and a grinding seat 24. The feed crushing device 22 is installed on the feed cylinder 21 and communicates with the inner cavity of the feed cylinder 21. The grinding seat 24 is provided on the side wall of the inner cavity of the feed cylinder 21. The grinding seat 24 is adapted to the grinding blocks 23. The grinding blocks 23 are rotatably installed in the feed cylinder 21 via a rotating shaft. The grinding seat 24 and the feed cylinder 21 are integrally constructed. The grinding seat 24 is located on the lower half of the inner cavity of the feed cylinder 21. A guide groove is provided on the upper half of the grinding blocks 23. The lower half has grinding blades, and the grinding seat 24 also has a guide groove. The lower half also has grinding blades that match the grinding blades of the grinding block 23. The end of the grinding seat 24 near the feeding crushing device 22 is set with a slope. Through the rotation of the grinding block 23, its guide groove can effectively disperse the powder when it enters the grinding area. The matching grinding blades form an effective grinding action, further refining the powder. At the same time, there is a distance between the two that allows the grinding powder to pass through, ensuring that the ground powder can flow out smoothly without causing blockage.
[0033] like Figure 5 As shown, the feeding crushing device 22 includes a feeding hopper 221 and crushing rollers 222. The feeding hopper 221 is mounted on the support platform 8. Several crushing rollers 222 are installed inside the feeding hopper 221. The feeding hopper 221 is provided with a feeding ramp. The number of crushing rollers 222 is preferably four. They are driven to rotate by four servo motors, which fully cover the area of the feeding hopper 221 connected to the feeding cylinder 21. The centripetal force generated by the rotation throws the crushed material into the feeding cylinder 21, which not only speeds up the feeding speed of the material, but also reduces the residue and accumulation of material in the feeding hopper 221. The discharge port of the feeding hopper 221 is provided with a flat slope. Bearings are installed in the flat slope to provide stable support and a rotation area for the crushing rollers 222. One end of each of the four crushing rollers 222 is connected to a servo motor, and the other end is connected to the flat slope through a bearing.
[0034] like Figure 1 , Figure 3 and Figure 4As shown, the mixing inner cylinder 3 includes a mixing inner cylinder 31, a mixing roller 32, and a scraper 33. Several mixing rollers 32 and scrapers 33 are rotatably installed inside the mixing inner cylinder 31 via a rotating shaft. The scraper 33 abuts against the bottom surface of the inner cavity of the mixing cylinder. The mixing inner cylinder 31 and the discharge box 4 are an integral structure. Several liquid outlet holes are opened on the bottom surface of the mixing inner cylinder 31. The liquid outlet holes are connected to the discharge box 4. The discharge box 4 is located between the supporting outer cylinder 1 and the mixing inner cylinder 31. The scraper 33 scrapes off the material adhering to the bottom surface of the inner cavity of the mixing inner cylinder 31 to prevent the material from accumulating and clumping on the bottom surface, ensuring the uniformity of mixing. During the mixing process, the mixture will inevitably flow out from the liquid outlet holes until it fills the discharge box 4. The mixing fan in the discharge box 4 ensures that the mixture in the discharge box 4 is also fully mixed until it is discharged. The discharge box 4 is connected to a liquid outlet pipe 100. During the discharge process, the scraper 33 can also effectively push the material into the liquid outlet holes.
[0035] like Figure 6 As shown, the discharge box 4 is equipped with a discharge ramp and a mixing fan. The mixing fan drive motor is located at the bottom of the support outer cylinder 1. Its drive end passes through the support outer cylinder 1, the bottom of the discharge box 4, and the discharge ramp inside the discharge box 4 and is connected to the mixing fan. During the discharge process, the mixing fan further stirs and mixes the material to ensure the uniformity of the material during discharge, especially for zinc plating additives that may produce stratification or precipitation during the reaction process, and can accelerate the discharge.
[0036] The heating zone 5 is equipped with several heaters 51, and the outer support cylinder 1 is equipped with a temperature sensor 52. The heaters 51 are preferably resistance heaters. Resistance wire heaters 51 have a fast heating speed and high efficiency, and can quickly transfer heat to the stirring inner cylinder 3, thereby improving the preparation efficiency of galvanizing additives. Four heaters are arranged in an array on the bottom side of the outer support cylinder 1, with the heating end penetrating the outer support cylinder 1 and located in the heating zone 5. The temperature sensor 52 is linked with the heaters 51 to ensure that the galvanizing additives are prepared under the optimal temperature conditions. The discharge box 4 is close to the resistance wire, which can maintain a certain temperature during the discharge process and reduce the material solidification caused by the temperature drop.
[0037] The first drive motor 7, grinding feed cylinder 2, heater 51, and temperature sensor 52 are all connected to the controller via communication.
[0038] Working principle: The staff introduces the material into the feed hopper 221. Due to the feed slope in the feed hopper 221, the material quickly reaches the crushing zone. As the crushing roller 222 rotates, the material is crushed and flows into the feed cylinder 21. Further, an appropriate amount of water is injected into the mixing cylinder 3 through the water inlet pipe 101. The heating medium is introduced into the heating zone 5 through the heating circulation pipe 103. The heater 51 is started to heat the material until the mixing reaches a suitable temperature. At the same time, the first drive motor 7 is started to drive the grinding block 23 to rotate, which, together with the grinding seat 24, further grinds the material entering the cylinder.
[0039] The powder is further ground and then fed into a mixing tank for uniform mixing to form a solution, which is then discharged from the discharge box 4.
