Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment agent mixing technology, and in particular to a stirring device for the production of metal surface treatment agents. Background Technology

[0002] Metal surface treatment agents refer to a general term for chemical agents used to treat metal surfaces in various ways. The preparation of metal surface treatment agents requires stirring of the chemical additives.

[0003] A metal surface treatment agent mixing device is an essential mixing equipment in the production process of metal surface treatment agents. Powder and solvent are put into the container of the mixing device, and the mixing device is used to mix them to produce the finished product.

[0004] However, some solvents are very viscous, and the viscosity of the metal surface treatment agents produced by stirring and mixing varies. During the stirring process, the overly viscous liquid mixture is difficult to mix quickly and thoroughly, and it is easy to stick to the side wall, requiring a longer stirring time and reducing the quality of the metal surface treatment agent. When the powder is fed, there are lumps of material, which are difficult to mix with the solvent in time. Utility Model Content

[0005] To solve the above-mentioned existing technical problems, this utility model provides a stirring device for the production of metal surface treatment agents.

[0006] The technical solution of this utility model is achieved through the following scheme: a stirring device for producing metal surface treatment agent, including a support frame, a cover and a rotating cylinder, wherein the rotating cylinder is rotatably mounted on the support frame, the cover is located at the top of the rotating cylinder, a stirring device is rotatably mounted on the cover, and several scrapers are detachably mounted on the cover. The stirring device and the scrapers are both located inside the rotating cylinder. A hopper is provided on the top surface of the cover, and a powder crushing device is provided inside the hopper. A heating system and a control panel are also provided on the support frame.

[0007] Through the above technical solutions, the rotating drum auxiliary mixing device mixes the materials. The rotation of the rotating drum generates additional shearing force, which helps the materials to mix more quickly and thoroughly, improving mixing efficiency. The scraper ensures that the material adhering to the side wall can be scraped off in time during the mixing process, avoiding the material from sticking to the side wall for a long time and causing uneven mixing. The powder crushing device can crush the lumpy material when the powder is fed, preventing the lumpy material from affecting the mixing effect. The heating system can appropriately heat the material to reduce its viscosity, making it easier to mix and thus shortening the mixing time.

[0008] Preferably, a screw pump is installed at the discharge port of the rotating cylinder, and the cover is movably mounted on the support frame via a screw lifting component.

[0009] Preferably, the stirring device includes a first motor, a stirring shaft, a plurality of stirring fans, and a feeding screw roller. The first motor is connected to the plurality of stirring fans through the stirring shaft. The first motor is installed on the top surface of the cover. A feeding screw roller is installed at the end of the stirring shaft and is located above the screw pump.

[0010] Through the above technical solutions, the screw pump ensures that the mixed metal surface treatment agent can be discharged smoothly and efficiently. The screw lifting component has a stable structure and flexible operation, which can ensure the safety of the cap during lifting and lowering. The first motor drives the mixing fan to rotate through the mixing shaft, which fully mixes the material. At the same time, the feeding screw roller can assist in feeding while mixing, ensuring that the material can smoothly enter the screw pump and be discharged after mixing.

[0011] Preferably, the outer surface of the rotating cylinder has external teeth, and the support frame is equipped with a second motor, the output end of which is fitted with a drive gear that matches the external teeth.

[0012] Preferably, the support frame is provided with a limiting ring and a bottom support, the bottom of the rotating material cylinder is attached to the bottom support, and a limiting protrusion is provided on the outer surface of the rotating material cylinder. The rotating material cylinder is rotatably mounted on the limiting ring through the limiting protrusion.

[0013] Through the above technical solutions, the circular protrusion makes the rotating cylinder rotate more smoothly within the limiting ring, reducing friction and wear, while also improving the accuracy of the limiting. Combined with the bottom support for double fixation, it makes the position of the rotating cylinder on the support frame more stable, effectively bearing the force generated during rotation, preventing the rotating cylinder from shifting or shaking during rotation, and ensuring the safe operation of the equipment.

[0014] Preferably, the heating system includes a heating plate and an infrared temperature sensor, which are mounted opposite each other on a support frame, and the rotating cylinder is located between the heating plate and the infrared temperature sensor.

[0015] Through the above technical solutions, the heating plate enables the rotating drum to be directly heated by the heat source, which quickly increases the temperature of the material inside the drum, reduces the viscosity of viscous materials, and improves the stirring efficiency. The infrared temperature sensor monitors the surface temperature of the rotating drum in real time. Together with the heating plate, a closed-loop temperature control system is formed to ensure that the material inside the drum is always kept within the set temperature range, avoiding the impact of excessively high or low temperatures on the stirring effect or product quality.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model uses a rotating drum auxiliary mixing device to mix materials. The rotation of the drum generates additional shearing force, which helps the materials to mix more quickly and thoroughly, improving mixing efficiency. The scraper ensures that the material adhering to the side wall can be scraped off in time during the mixing process, avoiding the material from sticking to the side wall for a long time and causing uneven mixing. The powder crushing device can crush the lumpy material when the powder is fed, preventing the lumpy material from affecting the mixing effect. The heating system can appropriately heat the material to reduce its viscosity, making it easier to mix and thus shortening the mixing time.

[0018] 2. The screw pump ensures that the mixed metal surface treatment agent can be discharged smoothly and efficiently. The screw lifting component has a stable structure and flexible operation, which can ensure the safety of the cap during lifting and lowering. The first motor drives the mixing fan to rotate through the mixing shaft, which fully mixes the material. At the same time, the feeding screw roller can assist in feeding while mixing, ensuring that the material can smoothly enter the screw pump and be discharged after mixing.

[0019] 3. The circular protrusions make the rotating cylinder rotate more smoothly within the limiting ring, reducing friction and wear, and also improving the accuracy of the limiting. Together with the bottom support, they provide double fixation, making the rotating cylinder more stable on the support frame. This effectively withstands the forces generated during rotation, preventing the rotating cylinder from shifting or shaking during rotation, and ensuring the safe operation of the equipment.

[0020] 4. The heating plate allows the rotating drum to be directly heated by the heat source, which quickly raises the temperature of the material inside the drum, reduces the viscosity of viscous materials, and improves the stirring efficiency. The infrared temperature sensor monitors the surface temperature of the rotating drum in real time. Together with the heating plate, it forms a closed-loop temperature control system to ensure that the material inside the drum is always kept within the set temperature range, avoiding the impact of excessively high or low temperatures on the stirring effect or product quality.

[0026] 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.

[0027] 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.

[0028] A stirring device for producing a metal surface treatment agent, such as Figures 1-4 As shown, the device includes a support frame 1, a cover 11, and a rotating drum 2. The rotating drum 2 is rotatably mounted on the support frame 1. The cover 11 is located on top of the rotating drum 2, and a stirring device 3 is rotatably mounted on the cover 11. Several scrapers 12 are detachably mounted on the cover 11, preferably four in a circular array. The scrapers 12 are screwed onto the cover 11. They can be removed for cleaning, maintenance, or replacement simply by removing the bolts and pushing them from the bottom. The stirring device 3 and the scrapers 12 are both located inside the rotating drum 2. The scrapers 12 abut against the inner wall of the rotating drum 2, scraping off the material adhering to the inner wall of the drum during rotation to prevent material accumulation and ensure that all materials participate in the mixing process. A hopper is provided on the top surface of the cover 11, and a powder crusher is installed in the hopper. The crushing device 5 and the support frame 1 are also equipped with a heating system 4 and a control panel 6. The second motor driving the rotating drum 2, the stirring device 3, the heating system 4, the powder crushing device 5 and the screw pump 10 are all connected to the control panel 6. The number of hoppers is preferably two, one for powder and one for solvent. The powder crushing device 5 is installed in the powder hopper. The stirring device 3 and the rotating drum 2 rotate in opposite directions, generating a strong stirring effect, which makes the solvent and powder form a complex flow and collision in the rotating drum 2, increasing the contact area and mixing opportunities between materials, so that the solvent and powder can be more fully mixed and stirred, improving the uniformity and quality of mixing. The heating system 4 on the support frame 1 heats the material in the rotating drum 2, promoting the dissolution, reaction or mixing of the material.

[0029] A screw pump 10 is installed at the discharge port of the rotating drum 2. The cover 11 is movably mounted on the support frame 1 via a screw lifting component. The cover 11 is integrally flange-connected to the screw lifting component. When it is necessary to clean and maintain the inside of the rotating drum 2, the cover 11 is lifted as a whole via the screw lifting component, so that the inside of the rotating drum 2 is completely exposed. Operators can easily use tools to thoroughly clean the inner wall of the rotating drum 2, the stirring device 3, and other parts, avoiding the cleaning difficulties caused by the cover 11 being difficult to disassemble or the space being too small.

[0030] like Figure 4 As shown, the powder crushing device 5 includes two third motors and two crushing rollers. The third motors drive the crushing rollers, which rotate in opposite directions and are arranged at an incline. Linear actuators are installed at the bottom of both the powder hopper and the solvent hopper. Baffles are installed at the telescopic ends of the linear actuators. The linear actuators push the baffles to adjust the size of the feed opening of the hopper, thereby controlling the feeding speed. The linear actuators are also connected to the control panel 6. The linear actuators are preferably servo electric cylinders, which effectively crush the powder entering the powder hopper, breaking large powder particles into smaller particles. The incline arrangement increases the residence time of the powder in the crushing zone, allowing for more thorough crushing. Furthermore, the inclined crushing rollers help the powder slide down naturally under its own gravity, preventing powder from accumulating above the crushing rollers, improving crushing efficiency, and reducing the risk of equipment blockage.

[0031] like Figure 2 and Figure 3 As shown, the rotating drum 2 consists of a cylindrical section and a frustum-shaped discharge section. The stirring device 3 includes a first motor, a stirring shaft 31, several stirring fans 32, and a discharge screw roller 33. The first motor is connected to several stirring fans 32 through the stirring shaft 31. The first motor is installed on the top surface of the cover 11. The discharge screw roller 33 is installed at the end of the stirring shaft 31 and is located above the screw pump 10. The number of stirring fans 32 is preferably three, with two stirring fans 32 located in the cylindrical section of the rotating drum 2 and the other stirring fan 32 located in the frustum-shaped discharge section and adapted to it. The mixed material is swept to the discharge screw roller 33 and the inner wall of the frustum-shaped discharge section is cleaned. The material is pushed forward while stirring, which improves the efficiency and smoothness of the discharge. The screw pump 10 is turned on to discharge the mixed treatment agent. The two stirring fans 32 in the cylindrical section are surrounded by scrapers 12.

[0032] The outer surface of the rotating cylinder 2 has external teeth. A second motor is installed on the support frame 1. The output end of the second motor is equipped with a drive gear that matches the external teeth. The second motor is preferably a geared motor, which reduces the output speed and increases the output torque, so that the rotating cylinder 2 can obtain sufficient power during startup and operation. It can operate smoothly even under a large load, avoiding problems such as equipment vibration and transmission failure caused by excessive motor speed or insufficient torque. The support frame 1 is equipped with a limiting ring 8 and a bottom support 9. The bottom of the rotating cylinder 2 rests on the bottom support 9. The outer surface of the rotating cylinder 2 is equipped with a limiting protrusion 7. The rotating cylinder 2 is rotatably mounted on the limiting ring 8 through the limiting protrusion 7. The limiting protrusion 7 is a circular protrusion that matches the limiting ring 8. The bottom support 9 and the limiting ring 8 fix the position of the rotating cylinder 2 to ensure that it will not be misaligned during rotation.

[0033] The heating system 4 includes a heating plate 41 and an infrared temperature sensor 42. The heating plate 41 and the infrared temperature sensor 42 are mounted opposite each other on the support frame 1. The rotating cylinder 2 is located between the heating plate 41 and the infrared temperature sensor 42. The heating plate 41 is fixed on the support frame 1 and abuts against the rotating cylinder 2. Since the rotating cylinder 2 is rotating, it can be heated evenly. The infrared temperature sensor 42 can measure the surface temperature of the rotating cylinder 2 in real time and accurately. When the temperature is lower than the set value, the control panel 6 controls the heating plate 41 to quickly increase the output power to raise the temperature. When the temperature is higher than the set value, the power is reduced or heating is stopped to achieve precise temperature control and avoid excessive temperature fluctuations. The heating plate 41 is preferably an arc-shaped ceramic heating plate 41.

[0034] Working principle: The operator introduces the powder and solvent into the corresponding feeding hoppers respectively. The powder crushing device 5 and the feeding speed of the two are controlled by the control panel 6. The mixing device 3 and the rotating drum 2 are further mixed and stirred. At the same time, the operator starts the heating system 4 to heat the side wall of the rotating drum 2 and monitors it in real time by the infrared temperature sensor 42 to prevent overheating. When the set value is reached, the infrared temperature sensor 42 sends a feedback signal to shut off the heating plate 41.

[0035] When mixing is complete and material needs to be discharged, stop rotating the material cylinder 2 and discharge the material through the discharge screw roller 33 at the lowest point of the mixing device 3. At the same time, turn on the screw pump 10 located at the discharge port to discharge the material.

[0036] The control panel 6 can precisely control the start, stop, and operating parameters of each component according to preset programs or real-time needs, avoiding waiting and idle time between components. The parts and equipment all adopt conventional models in the prior art, and the circuit connection and communication connection adopt conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
