Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary equipment for leveling liquid production, and in particular to a mixing device for cold rolling leveling liquid media. Background Technology
[0002] In the field of cold-rolled sheet and strip production, cold-rolled sheet and strip production lines are widely used in many industries such as automobile manufacturing, electrical products, locomotives and rolling stock, aviation, precision instruments, and canned food because they do not require a heating process. With the continuous advancement of technology, the market has put forward more stringent requirements for the surface quality of cold-rolled sheet and strip products.
[0003] As a key factor affecting product quality in cold-rolled strip production lines, leveling fluid plays an important role in the production process. It can effectively clean the dirt on the surface of the strip steel and significantly improve the cleanliness of the strip steel surface. The leveling fluid is mainly composed of organic alcohol amines, organic alkalis and pure water. With the help of organic alkalis, the solution is alkaline, which in turn forms a viscous and stable and uniform emulsion state, and appears as a transparent light yellow liquid.
[0004] A mixing and leveling liquid tank with a self-sterilization function is disclosed in Chinese Patent CN 219193285 U. The tank includes a tank body with a lid on its top surface, a liquid guide port on the outer circular wall of the tank body, a conduit fixedly installed inside the liquid guide port, and an installation hole on the top surface of the lid. A sterilization component is disposed inside the tank body for sterilizing the leveling liquid mixture. By incorporating the sterilization component, ultraviolet lamps sterilize the leveling liquid mixture in real time, effectively controlling bacterial growth in the mixture due to environmental influences and solving the problem of occasional bacterial growth in the leveling liquid mixture and the long-term accumulation of bacteria on the pipe walls.
[0005] However, the raw materials for the leveling liquid react prematurely at the side wall of the inlet during the process of being transported into the mixing device. The mixture sticks to the side wall of the inlet, resulting in uneven mixing. In addition, the temperature and humidity of the workshop environment will continue to change. Under these conditions, the temperature distribution of the mixture is uneven during the mixing process, which affects the physical and chemical properties of the mixture and leads to unstable quality of the prepared leveling liquid.

[0008] Through the above technical solutions, the separation of the feed pipe reduces premature reaction and adhesion of materials at the side wall of the feed inlet, ensuring that the materials can enter the mixing tank more evenly; the heating box heats the materials in the mixing tank, and with the heat conduction effect of the internal leveling liquid, the leveling liquid raw materials that enter later can be at a suitable temperature, maintaining the uniformity of the temperature distribution of the mixture and improving the mixing effect.
[0009] Preferably, the separating feed pipe includes an outer cylinder, an inner cylinder, and a first flow-slowing hood. The outer cylinder is sleeved on the inner cylinder and passes through the cap. The first flow-slowing hood is installed at one end of the inner cylinder located in the inner cavity of the mixing tank, and the discharge end of the outer cylinder is located above the first flow-slowing hood.
[0010] Preferably, the outer cylinder and the cap are integrally formed, and the first flow-slowing hood is adapted to the inner cavity of the outer cylinder.
[0011] Through the above technical solutions, the integrated design of the outer cylinder and the cap enhances the connection strength and sealing performance, reducing the risk of material leakage caused by loose parts or poor sealing. The first flow-slowing hood diverts and slows the flow of material discharged from the outer cylinder, so that the raw material in the outer cylinder is evenly distributed into the mixing tank, avoiding direct impact of material on the liquid or material in the mixing tank. The outer and inner cylinders are fed separately at the same time, reducing the residence time of material at the side wall of the inlet, reducing the risk of material adhesion and blockage, and ensuring the smooth flow of material.
[0012] Preferably, the stirring device includes a drive motor, a push fan, and several stirring fans. The drive motor is embedded in the bottom of the stirring tank, and the drive motor is connected to the push fan and several stirring fans in sequence through a stirring shaft. The push fan abuts against the bottom of the inner cavity of the stirring tank.
[0013] Preferably, a second flow-slowing shroud is provided at the end of the stirring shaft, and the second flow-slowing shroud is directly opposite the outlet of the separating feed pipe.
[0014] Through the above technical solutions, multiple stirring fans comprehensively cover and stir the mixing tank, effectively preventing material residue at the bottom of the tank, ensuring thorough discharge, and reducing waste caused by material residue; the second flow-diverting hood diverts the discharge from the inner cylinder, and can also reduce the direct impact of material on the stirring shaft and stirring fans, protecting the stirring device from damage and extending the service life of the equipment.
[0015] Preferably, the outer surface of the mixing tank is provided with a rounded protrusion, the heating box is located between the rounded protrusion and the discharge port, and the heating box is provided with a temperature sensor and a heating plate.
[0016] Through the above technical solutions, by monitoring and feeding back the heating temperature in real time, the controller can adjust the power or on / off status of the heating plate in a timely manner, thereby avoiding overheating and adverse effects on the leveling liquid in the mixing tank.
[0017] In summary, this utility model has the following beneficial effects:
[0018] 1. This utility model reduces premature reaction and adhesion of materials at the side wall of the feed inlet by separating the feed pipe, ensuring that the materials can enter the mixing tank more evenly; the heating box heats the materials in the mixing tank, and with the heat conduction effect of the internal leveling liquid, the leveling liquid raw materials that enter later can be at a suitable temperature, maintain the uniformity of temperature distribution of the mixture, and improve the mixing effect.
[0019] 2. The integrated design of the outer cylinder and the cap enhances the connection strength and sealing performance, reducing the risk of material leakage due to loose parts or poor sealing. The first flow-slowing hood diverts and slows the flow of material discharged from the outer cylinder, ensuring that the raw material in the outer cylinder is evenly distributed into the mixing tank. This avoids the material directly impacting the liquid or material in the mixing tank. The outer and inner cylinders are fed separately at the same time, reducing the residence time of the material at the side wall of the inlet, reducing the risk of material adhesion and blockage, and ensuring smooth material flow.
[0020] 3.

[0030] 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.
[0031] 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.
[0032] A cold-rolled leveling liquid medium mixing device, such as Figures 1-5As shown, the system includes a mixing tank 1, a separating feed pipe 2, and a heating box 4. A stirring device 3 is installed inside the mixing tank 1. A detachable cover 9 is installed on the top of the mixing tank 1. The separating feed pipe 2 passes through the cover 9. A sterilization lamp 6 is installed on the side of the cover 9 facing the inner cavity of the mixing tank 1. A liquid level sensor 10 is installed on the inner wall of the mixing tank 1 below the sterilization lamp 6. A controller 7 and a heating box 4 are installed sequentially from top to bottom on the outer surface of the mixing tank 1. A discharge port 8 is opened at the bottom of the mixing tank 1. A sterilization lamp 6 drive source is installed on the top surface of the cover 9. Electric valves are installed on both the discharge port 8 and the separating feed pipe 2. The cover 9 is screwed onto... At the top opening of the mixing tank 1, the sterilization lamp 6 is embedded in the cover 9 and connected to the sterilization lamp 6 drive source. The sterilization lamp 6 can effectively kill bacteria and other microorganisms in the mixing tank 1, effectively control the impact of workshop humidity changes on bacterial growth when mixing the leveling liquid in the mixing tank 1, solve the problem of long-term accumulation of bacteria on the pipe wall, and work with the liquid level sensor 10 to monitor the material liquid level in real time, providing operators with accurate liquid level information, facilitating the control of the feeding amount, and effectively preventing the leveling liquid from exceeding the position and damaging the sterilization lamp 6. The separation feed pipe 2 synchronously separates and feeds the leveling liquid raw materials, avoiding premature mixing and adhesion of the leveling liquid raw materials.
[0033] The electric valve, the sterilization lamp 6 drive source, the liquid level sensor 10, the temperature sensor 5, the stirring device 3 and the heating box 4 are all connected to the controller 7, which is preferably a PLC controller 7.
[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the outer surface of the mixing tank 1 has a rounded protrusion. The heating box 4 is located between the rounded protrusion and the discharge port 8. The heating box 4 is equipped with a temperature sensor 5 and a heating plate. The heating box 4 is divided into two halves, which are screwed onto the rounded protrusion. These halves serve as the positioning and support points for the heating box 4, making the installation of the heating box 4 more stable and less prone to shaking. The heating box 4 has a built-in heating plate and temperature sensor 5. The heating plate heats the mixing tank 1 quickly and evenly. The temperature sensor 5 monitors the heating temperature in real time and feeds the data back to the controller 7, ensuring the accuracy and controllability of the heating process and avoiding adverse effects from overheating, such as damaging the chemical properties of the leveling liquid or causing it to deteriorate. The two halves of the heating box 4 make maintenance and replacement easier. When the heating plate or temperature sensor 5 malfunctions, the corresponding parts can be easily disassembled and replaced without large-scale disassembly of the entire mixing tank 1. The heating plate heats the lower half of the mixing tank 1, and together with the thermal conductivity of the internal leveling liquid, ensures that the leveling liquid raw materials entering later are at a suitable temperature, reducing unnecessary energy consumption.
[0035] like Figure 4 and Figure 5As shown, the separating feed pipe 2 includes an outer cylinder 21, an inner cylinder 22, and a first flow-retardant hood 23. The outer cylinder 21 is fitted onto the inner cylinder 22 and passes through the cap 9. The first flow-retardant hood 23 is installed at one end of the inner cylinder 22 located inside the mixing tank 1. The overall length of the inner cylinder 22 is longer than that of the outer cylinder 21, and the first flow-retardant hood 23 is located at the discharge port 8 of the inner cylinder 22, ensuring that the raw materials in the outer cylinder 21 and the inner cylinder 22 are thoroughly mixed after entering the mixing tank. The first flow-retardant hood 23 is integrally formed with the inner cylinder 22. It is shaped like an inverted funnel and diverts and slows the flow of material from the outer cylinder 21. The discharge end of the outer cylinder 21 is located above the first slowing hood 23. The outer cylinder 21 and the cover 9 are integrated. The first slowing hood 23 is adapted to the inner cavity of the outer cylinder 21, making it easy to disassemble and pull out the inner cylinder 22. When the material flows out from the outer cylinder 21, the inverted funnel-shaped first slowing hood 23 can expand the dispersion area of the material, reduce the material flow rate, avoid the material directly impacting the stirring device 3 in the mixing tank 1, and effectively reduce splashing and reduce foam or eddy phenomena caused by impact.
[0036] The stirring device 3 includes a drive motor 31, a push fan 32, and several stirring fans 33. The drive motor 31 is embedded in the bottom of the stirring tank 1. The drive motor 31 is connected to the push fan 32 and several stirring fans 33 in sequence through the stirring shaft. The push fan 32 abuts against the bottom of the inner cavity of the stirring tank 1. The push fan 32 and two stirring fans 33 are installed in sequence on the stirring shaft. The push fan 32 is close to the stirring tank 1. When discharging the leveling liquid, the push fan 32 applies a pushing force to the material at the bottom of the tank in the direction of the discharge port 8, which effectively speeds up the discharge speed and reduces the discharge time.
[0037] A second flow-damping shroud 34 is provided at the end of the stirring shaft. The second flow-damping shroud 34 is conical in shape and is directly opposite the outlet 8 of the separating feed pipe 2. It is directly opposite the axis of the outlet 8 of the inner cylinder 22 of the separating feed pipe 2, and diverts the material out of the inner cylinder 22, so that the material is more evenly dispersed into the mixing tank 1. The two stirring fans 33 rotate under the drive of the drive motor 31 to fully stir the material in the mixing tank 1. During the stirring process, the push fan 32 can also participate in the stirring to a certain extent, working together with the stirring fan 33 to enhance the stirring effect.
[0038] Working principle: The operator starts the electric valve of the separation feed pipe 2 through the controller 7 to synchronously separate and feed the leveling liquid raw material. At this time, the raw material in the outer cylinder 21 is diverted and slowed by the first slow flow hood 23, while the raw material in the inner cylinder 22 is diverted and slowed by the second slow flow hood 34.
[0039] At the same time, the staff started the heating plate and drive motor 31 in the heating box 4, so that the leveling liquid raw material was stirred at a suitable temperature to improve the mixing quality. When the liquid level in the mixing tank 1 reached the detection position of the liquid level sensor 10, a signal was sent to the controller 7, which then closed the electric valve of the separation feed pipe 2, stopped the feeding, and further turned on the sterilization lamp 6 for sterilization.
[0040] The inside of the mixing tank 1 can be cleaned simply by removing the 9 bolts on the cover.
[0041] All parts and equipment use conventional models in the existing technology. In addition, the circuit connection and communication connection adopt conventional connection methods in the existing technology, 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.
[0042] 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.
