Description

Technical Field

[0001] This utility model relates to the field of emulsion dilution technology, specifically a dilution device for organosilicon emulsions. Background Technology

[0002] Organosilicon emulsions are stable emulsion systems formed by dispersing organosilicon polymers in an aqueous phase through an emulsification process. They possess hydrophobicity, lubricity, and chemical inertness. Their particle size is typically 0.1-10 micrometers, and their stability is maintained by surfactants. During production, water and thickeners must be added to dilute the organosilicon emulsion.

[0003] In the prior art, the authorized announcement number CN218573450U discloses a dilution device for processing silicone adhesive, including a dilution tank. Two feeding ports are fixedly connected to the outer surface of the dilution tank and are in communication with the dilution tank. A discharge pipe is fixedly connected to the bottom end of the dilution tank and is in communication with the dilution tank. A motor is fixedly connected to the top end of the dilution tank, and a main stirring roller is fixedly connected to the output end of the motor.

[0004] The silicone emulsion can be effectively diluted by thoroughly mixing and stirring it with the diluent in a mixing and dilution tank. The diluted silicone emulsion is then discharged through a discharge port located at the bottom of the tank. However, despite the dilution, the silicone emulsion remains quite viscous with relatively poor flowability, resulting in a prolonged discharge time. This slow discharge not only extends the production cycle but also negatively impacts overall production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a dilution device for silicone emulsions to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dilution device for silicone emulsion, comprising a dilution tank, an inlet fixedly installed at the upper end of the dilution tank, a sealing cap provided at the inlet, a discharge port opened at the bottom of the dilution tank, and a valve connected to the discharge port, a stirring mechanism installed on the dilution tank, the stirring mechanism comprising a mounting frame fixedly installed at the top of the dilution tank, a motor fixedly installed at the upper end of the mounting frame, a stirrer installed on the mounting frame, and a pressurizing mechanism installed at the top of the dilution tank.

[0007] Preferably, a coupling is installed at the output end of the motor, a drive shaft is connected to the coupling, and a first electromagnetic clutch is installed between the drive shaft and the agitator.

[0008] Preferably, a bearing is installed inside the mounting frame, and the agitator is rotatably mounted on the mounting frame via the bearing.

[0009] Preferably, the drive shaft is fixedly installed at the output end of the motor via a coupling, the lower end of the drive shaft is fixedly installed at the input end of the first electromagnetic clutch, and the upper end of the agitator is fixedly installed at the output end of the first electromagnetic clutch.

[0010] Preferably, the pressurization mechanism includes a positioning frame and a piston pump fixedly mounted on the dilution tank. A planetary reducer is fixedly mounted on the positioning frame, and the output end of the planetary reducer is connected to the input end of the piston pump. A second electromagnetic clutch is fixedly mounted on the front end of the planetary reducer. A drive shaft is installed between the second electromagnetic clutch and the drive shaft. Helical gears are fixedly mounted on both the input shaft and the drive shaft, and the two helical gears mesh together. An air inlet pipe and an air outlet pipe are fixedly mounted on the piston pump, and the air outlet pipe extends into the interior of the dilution tank. A filter screen is installed at the end of the air inlet pipe.

[0011] Preferably, a retainer is fixedly installed on the upper surface of the dilution tank, and a bearing is installed inside the retainer. The input shaft is rotatably mounted on the retainer via the bearing.

[0012] Preferably, the output end of the second electromagnetic clutch is connected to the input end of the piston pump, and the end of the input shaft is fixedly mounted on the input end of the second electromagnetic clutch.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, after the silicone emulsion and diluent are injected into the dilution tank, the engagement state of the first electromagnetic clutch can be controlled, and then the motor is started. After the motor starts, the drive shaft rotates accordingly, which in turn drives the stirrer to rotate, thereby achieving uniform mixing of the silicone emulsion and diluent and completing the dilution process of the silicone emulsion.

[0015] 1. In this application, when the second electromagnetic clutch is engaged, the drive shaft drives the input shaft to rotate. Subsequently, the rotation of the input shaft drives the piston pump. The operation of the piston pump pumps air into the dilution tank, causing an increase in the air pressure inside the tank. After opening the valve on the inlet, the silicone emulsion in the dilution tank will be rapidly discharged under air pressure, thereby shortening the total dilution time and improving dilution efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a dilution device for silicone emulsion, including a dilution tank 1. A feed inlet 2 is fixedly installed on the upper end of the dilution tank 1, and a sealing cover 3 is provided on the feed inlet 2. A discharge port 4 is opened at the bottom of the dilution tank 1, and a valve is connected to the discharge port 4. A stirring mechanism 5 is installed on the dilution tank 1, and a pressurizing mechanism 6 is installed on the top of the dilution tank 1. Through the cooperation of the stirring mechanism 5 and the pressurizing mechanism 6, the silicone emulsion in the dilution tank 1 can be quickly discharged under the action of air pressure, shortening the overall time of the dilution operation and improving the dilution efficiency.

[0023] like Figure 2 and Figure 3 As shown, the stirring mechanism 5 includes a mounting bracket 502 fixedly installed on the top of the dilution tank 1. A motor 501 is fixedly installed on the upper end of the mounting bracket 502. A stirrer 504 is installed on the mounting bracket 502. A coupling 505 is installed at the output end of the motor 501. A drive shaft 506 is connected to the coupling 505. A first electromagnetic clutch 503 is installed between the drive shaft 506 and the stirrer 504. A bearing is installed inside the mounting bracket 502. The stirrer 504 is rotatably mounted on the mounting bracket 502 through the bearing.

[0024] Specifically, after the silicone emulsion and diluent are injected into the dilution tank 1, the first electromagnetic clutch 503 can be engaged. When the first electromagnetic clutch 503 is engaged, the motor 501 can be started. Once started, the motor 501 will quickly drive the drive shaft 506 to rotate. During the rotation of the drive shaft 506, it will further drive the agitator 504 connected to it to rotate. The high-speed rotation of the agitator 504 can effectively mix the silicone emulsion and diluent thoroughly, ensuring that the two are mixed evenly, thereby achieving the purpose of diluting the silicone emulsion and successfully completing the dilution process.

[0025] like Figure 2 and Figure 4 As shown, the pressurization mechanism 6 includes a positioning frame 604 and a piston pump 606 fixedly mounted on the dilution tank 1. A planetary reducer 605 is fixedly mounted on the positioning frame 604, and the output end of the planetary reducer 605 is connected to the input end of the piston pump 606. A second electromagnetic clutch 603 is fixedly mounted at the front end of the planetary reducer 605. An input shaft 602 is installed between the second electromagnetic clutch 603 and the drive shaft 506. Helical gears 601 are fixedly mounted on both the input shaft 602 and the drive shaft 506, and the two helical gears 601 mesh with each other. An air inlet pipe 608 and an air outlet pipe 609 are fixedly mounted on the piston pump 606, and the air outlet pipe 609 extends into the interior of the dilution tank 1. A filter screen 607 is installed at the end of the air inlet pipe 608. A retainer is fixedly mounted on the upper surface of the dilution tank 1, and a bearing is installed inside the retainer. The input shaft 602 is rotatably mounted on the retainer through the bearing.

[0026] Specifically, when the second electromagnetic clutch 603 is engaged, the drive shaft 506 drives the input shaft 602 to rotate. During rotation, the input shaft 602 further transmits power, causing the connected piston pump 606 to start operating. Once the piston pump 606 is running, it pumps external air into the dilution tank 1, causing the air pressure inside the tank to gradually increase. When the air pressure inside the tank 1 reaches a certain level, the operator opens the valve on the inlet 2. At this point, the silicone emulsion inside the tank 1 is rapidly and efficiently discharged through the valve under the strong pressure of the air. This pneumatically driven rapid discharge method not only significantly shortens the overall time of the dilution operation but also greatly improves its efficiency, making the entire dilution process more efficient and smooth.

[0027] Working Principle: During operation, the silicone emulsion and diluent are first injected into dilution tank 1. After injection, the first electromagnetic clutch 503 is engaged, activating motor 501. Motor 501 drives drive shaft 506, which in turn drives agitator 504, ensuring uniform mixing of the silicone emulsion and diluent, thus completing the dilution process. After dilution, the second electromagnetic clutch 603 is engaged, activating drive shaft 506 and input shaft 602. Input shaft 602 then drives piston pump 606, which pumps air into dilution tank 1, increasing the pressure. Opening the valve at inlet 2 allows the silicone emulsion in tank 1 to be rapidly discharged under this pressure, shortening the overall dilution time and improving efficiency.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
