Description

Technical Field

[0001] This invention relates to the field of metal rolling technology, and more specifically, to an emulsion mill dispensing system and a method for accelerating emulsion emulsification. Background Technology

[0002] In the cold rolling process of metal sheet and strip, emulsion is a key lubricating and cooling medium. Its emulsification effect and particle size uniformity directly affect the stability of the rolling process, the surface quality of the strip, and the service life of the rolls. The preparation of emulsion usually requires mixing the oil phase and water phase in a certain proportion and emulsifying them fully through heating, stirring, etc., to achieve the target particle size (usually 0.4~0.8μm).

[0003] However, traditional emulsion preparation methods have the following drawbacks: long emulsification time, often requiring several hours or even longer to reach a stable emulsion state, affecting production efficiency; uneven particle size distribution, affecting lubrication and cooling effects; the preparation process relies heavily on manual operation, with low automation and poor control precision; and high energy consumption and low emulsification efficiency. Therefore, there is an urgent need for a system and method that can quickly, stably, and automatically complete emulsion preparation. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The present invention aims to solve the problems of low emulsification efficiency, uneven particle size, and poor automation in the prior art, and provides an emulsion mill dispensing system and a method for accelerating emulsion emulsification.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An emulsion mill dispensing system includes: an automatic emulsion mixer, a mixing tank, a level gauge, a thermocouple, a stirrer, an emulsion output pump, and an air diaphragm pump;

[0009] The outlet of the automatic emulsion mixer is connected to the inlet of the mixing tank via a pipeline;

[0010] The mixing tank is equipped with the level gauge, the thermocouple, and the stirrer;

[0011] The outlet of the mixing tank is connected to the inlet of the emulsion output pump via a pipeline;

[0012] The outlet of the emulsion output pump is connected to the inlet of the air diaphragm pump.

[0013] Furthermore, the pipeline between the outlet of the mixing tank and the emulsion output pump is a 1-inch pipeline, and the emulsion output pump is a high-power shear pump used to shear and refine the emulsion.

[0014] Furthermore, the level gauge, the thermocouple, and the stirrer are all connected to the automatic control system; the automatic control system is configured to: start heating when the level gauge detects that the emulsion level has exceeded the thermocouple, and start stirring when the emulsion level has exceeded the stirrer.

[0015] The present invention also provides a method for accelerating emulsion emulsification based on the above system, comprising the following steps:

[0016] Step S1: Prepare the emulsion by mixing water and oil at a mass ratio of 10:1 to 13:1, and perform preliminary mixing using the automatic emulsion mixer. The prepared emulsion is then fed into the mixing tank through a pipeline.

[0017] Step S2: When the emulsion level in the mixing tank exceeds the thermocouple, the heating will be automatically turned on; when the emulsion level exceeds the stirrer, the stirrer will be automatically turned on.

[0018] Step S3: When the emulsion in the mixing tank is filled to a volume of 1.8-2.2m³, control the emulsion temperature to 45-55℃ and stir at this temperature for at least 20 minutes.

[0019] Step S4: The emulsion processed in step S3 is transported to the emulsion output pump through pipeline. The emulsion is sheared and refined by the emulsion output pump. Then, the flow rate is controlled to be 0.67-1.0 m³ / h by the air diaphragm pump and the emulsion is transported to the rolling mill system.

[0020] Furthermore, in step S3, the heating temperature of the emulsion is 5-10°C higher than the conventional solution preparation temperature, reaching 50-55°C.

[0021] Furthermore, in step S4, the particle size of the emulsion after shearing and refining by the emulsion output pump is 0.4-0.6 μm.

[0022] Furthermore, in step S2, the start and stop of the level gauge, thermocouple, and stirrer are controlled in conjunction with the automatic control system to automate the liquid preparation process.

[0023] Furthermore, in step S4, the flow rate is controlled by an air diaphragm pump so that 2 m³ of emulsion is fed into the rolling mill system within 2-3 hours.

[0024] Compared with existing technologies, the advantages of this invention are as follows: Multi-stage synergistic emulsification with high efficiency: Through the initial mixing of the automatic mixer, the heating and stirring of the mixing tank, and the shearing and refining of the emulsion output pump, a three-stage synergistic emulsification effect is formed, significantly shortening the emulsification time; Uniform and fine particle size: Through the shearing action of the high-power emulsion output pump, combined with flow control, the emulsion particle size is refined to 0.4-0.6μm, with good uniformity, meeting the requirements of high-end rolling; High degree of automation: Through the linkage control of the level gauge, thermocouple, and stirrer, automatic start and stop of heating and stirring are realized, reducing manual intervention and improving control accuracy and stability; Stable and controllable delivery: The output flow rate is controlled by an air diaphragm pump, ensuring that the emulsion is stably delivered to the rolling mill system at a constant flow rate, avoiding the impact of flow fluctuations on the rolling process; Strong applicability: The system has a compact structure and clear methods and steps, and can be widely applied to emulsion preparation in various metal rolling production lines.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] As shown in the figure, this embodiment provides an emulsion mixing system for an emulsion rolling mill, including: an automatic emulsion mixer 1, a mixing tank 2, a level gauge 3, a thermocouple 4, a stirrer 5, an emulsion output pump 6, and an air diaphragm pump 7.

[0030] The outlet of the automatic emulsion mixer 1 is connected to the top inlet of the mixing tank 2 via a pipeline. The mixing tank 2 is equipped with a level gauge 3, a thermocouple 4, and a stirrer 5. The level gauge 3 is used to monitor the emulsion level in the mixing tank 2 in real time, the thermocouple 4 is used to detect the emulsion temperature, and the stirrer 5 is used to mechanically stir the emulsion. The bottom outlet of the mixing tank 2 is connected to the inlet of the emulsion output pump 6 via a 1-inch pipeline. The emulsion output pump 6 is a high-power shear pump used to shear and refine the emulsion. The outlet of the emulsion output pump 6 is connected to the inlet of the air diaphragm pump 7 via a pipeline. The air diaphragm pump 7 is used to deliver the finished emulsion to the rolling mill system at a constant flow rate.

[0031] The level gauge 3, thermocouple 4, and stirrer 5 are all electrically connected to the automatic control system (not shown in the figure). The automatic control system is configured as follows: when the level gauge 3 detects that the emulsion level has exceeded the thermocouple 4, the heating device (not shown in the figure) is activated to heat the emulsion; when the level gauge 3 detects that the emulsion level has exceeded the stirrer 5, the stirrer 5 is activated to stir.

[0032] Example 2

[0033] This embodiment provides a method for accelerating emulsion emulsification using the system described in Embodiment 1, specifically including the following steps:

[0034] Step S1: Prepare 2 m³ of emulsion with a water-to-oil mass ratio of 12:1 and an initial concentration of approximately 2.5%. The emulsion is initially mixed using an automatic emulsion mixer 1, and then piped into a mixing tank 2.

[0035] Step S2: When the emulsion level in the mixing tank 2 gradually rises, and the level gauge 3 detects that the level has overflowed the thermocouple 4, the automatic control system starts the heating device to heat the emulsion to 50°C; when the level rises further to overflow the stirrer 5, the automatic control system starts the stirrer 5, and the stirring speed is set to 80 r / min.

[0036] Step S3: Continue to add liquid until the mixing tank 2 is full (volume 2m³), maintain the emulsion temperature at 50±2℃ through the automatic control system, and stir at this temperature for 25 minutes.

[0037] Step S4: The emulsion processed in step S3 is transported to the emulsion output pump 6 through a 1-inch pipeline. The emulsion is sheared and refined by the emulsion output pump 6, and the particle size of the sheared emulsion is measured to be 0.45 μm. Then, the emulsion enters the air diaphragm pump 7. By adjusting the inlet pressure of the air diaphragm pump 7, the output flow rate is controlled to be 0.8 m³ / h, and the emulsion is stably delivered to the rolling mill system. 2 m³ of emulsion is delivered within 2.5 hours.

[0038] In this embodiment, the entire liquid preparation process is automated and requires no manual intervention. The emulsification time is short, and the emulsion particles are uniform and fine, which fully meets the requirements of the rolling mill.

[0039] Example 3

[0040] This embodiment is basically the same as embodiment 2, except that: the mass ratio of water to oil is 10:1, the heating temperature in step S3 is 55°C, and the mixture is stirred at a constant temperature for 20 minutes, resulting in a final emulsion particle size of 0.5μm.

[0041] Example 4

[0042] This embodiment is basically the same as embodiment 2, except that: the mass ratio of water to oil is 13:1, the heating temperature in step S3 is 45℃, and the constant temperature stirring is carried out for 30 minutes, resulting in a final emulsion particle size of 0.48μm.
