Description

Technical Field

[0001] This utility model relates to the field of silicone defoamer production technology, specifically to an auxiliary feeding device for silicone defoamer production. Background Technology

[0002] The production of silicone defoamers involves using silicone oil as the main raw material and processing it through specific processes to create a chemical additive with rapid foam-breaking properties. The production process integrates formulation design, chemical reaction, and physical processing technologies. As a highly efficient chemical additive, silicone defoamers are widely used in chemical, papermaking, and food processing industries. The production process involves the precise proportioning and mixing of various raw materials (such as silicone oil, emulsifiers, and carriers). The accuracy, uniformity, and efficiency of material feeding directly affect the defoaming performance and process stability of the final product.

[0003] For example, application number CN202110339363.8, with an authorization announcement date of 20211210, describes a feeding emulsification device and its working method for defoamer preparation. This device, belonging to the field of defoamer preparation technology, includes a working plate with a liquid tank fixedly connected to its top and a moving platform fixedly connected to one side of the liquid tank. The feeding emulsification device and its working method utilize a rotating shaft, a second worm gear, and a first servo motor. The first servo motor starts, driving the rotating shaft to stir the raw materials inside the emulsification tank, accelerating the emulsification speed. A transmission gear, rack, and first worm gear are also included. When the raw material inside the hopper reaches a certain amount, the first bevel gear meshes with the second bevel gear, causing the first worm gear to rotate. This moves the hopper towards the emulsification tank. As the hopper passes the rack, it rotates, causing the raw material inside the hopper to pour into the emulsification tank. This makes feeding convenient and allows for automatic feeding, thereby improving the device's working efficiency.

[0004] Traditional feeding processes rely heavily on manual operation or simple mechanical devices. Although they can achieve premixing during the feeding process, they are only designed for the emulsification process and do not integrate agglomeration and crushing functions. Powdered raw materials are prone to leaving agglomerates. Therefore, there is an urgent need to design an auxiliary feeding device for the production of silicone defoamers to solve the above problems. Utility Model Content

Through the linkage between the weighing sensor 8 and the weighing bucket 9, dynamic monitoring and control of the feeding amount are realized. One end of the conical shell 10 is located inside the weighing bucket 9. A discharge valve 7 is threaded to the center of one end of the weighing bucket 9. The discharge valve 7 is preferably a Camozzi 316L stainless steel solenoid valve.

The structure can monitor the weight of materials in real time, achieve precise control of feeding errors, ensure the accuracy of the proportion of key raw materials such as silicone oil and emulsifiers, avoid the accumulation of errors in traditional manual feeding, and ensure the stability of product batches. A stirring component 6 is installed at the top center of the support plate 1 by bolts. The stirring component 6 includes a shell 12, and a drive component 13 is provided at the top of the shell 12. The output end of the drive component 13 is provided with a connecting shaft tube 15. A grinding block 14 is installed at the top of the connecting shaft tube 15 by a flat key.

When the material enters the weighing tank 9, protective gas can be introduced into the connecting pipe 20 through the connecting pipe 19. Then the gas will enter the connecting piece 29 and then the connecting shaft tube 15, and then be ejected from the bottom of the connecting shaft tube 15 to protect the material from being crushed and stirred inside the tank 3. The gas will then be discharged from the exhaust pipe 18.

[0033] In another embodiment provided by this utility model, such as Figure 4 As shown, a spiral blade 17 is welded to the outside of the connecting shaft tube 15. The spiral blade 17 forces the mixture to mix the materials and improves uniformity. A scraper 16 is welded to the outer wall of one side of the connecting shaft tube 15. The scraper 16 prevents the material from sticking to the inner wall, reduces the cleaning frequency, and reduces raw material loss. The spiral blade 17 and the scraper 16 are located inside the weighing barrel 9.

[0034] In another embodiment provided by this utility model, such as Figure 1-2 and Figure 6 As shown, the top two outer walls of the support plate 1 are equipped with feeding cylinders 4, and a feeding hopper 5 is welded to one end of the feeding cylinder 4 as a material inlet. An installation pipe 28 is inserted into the center of one end of the feeding cylinder 4, and a cylinder shell 25 is bolted to one end of the installation pipe 28. A feeding motor 26 is bolted to one end of the cylinder shell 25. The feeding motor 26 is preferably a SEWEurodrive gear reduction motor. The feeding motor 26 drives the auger 27 to rotate, realizing controllable material conveying. The output end of the feeding motor 26 is mounted with the auger 27 through a flat key. The auger 27 is designed for high-viscosity materials such as silicone oil, and the conveying speed is adjustable to avoid blockage. The auger 27 is in contact with the inner wall of the cylinder shell 25.

[0035] In another embodiment provided by this utility model, such as Figure 3 As shown, four mounting ports 11 are provided on one side of the outer wall of the tank body 3. The mounting ports 11 are located on the side wall of the tank body 3 and support four independent material supply channels. One end of the shell 25 is installed inside the mounting port 11 by bolts.

[0036] Working principle: The auxiliary feeding device used in the production of this silicone defoamer follows the following working process:

[0037] 1. Multi-channel material conveying

[0038] Feeding stage: Raw materials such as silicone oil, emulsifier, and carrier enter the feeding cylinder 4 through the feeding hopper 5. The feeding motor 26 drives the auger 27 to rotate, and the material is conveyed along the cylinder shell 25 to the weighing tank 9 through the spiral propulsion action.

[0039] 2. Dynamic weighing and feedback control

[0040] Precise metering: The weighing tank 9 monitors the material weight in real time through the weighing sensor 8, with the error controlled within ±0.5%. When the preset feeding amount is reached, the feeding motor 26 of the corresponding feeding cylinder 4 is automatically turned off.

[0041] Multi-raw material synergy: The four mounting ports 11 on the side wall of the tank can be connected to multiple shells 25 simultaneously, supporting independent feeding of multiple raw materials such as silicone oil and emulsifiers through separate channels, ensuring accurate proportioning.

[0042] 3. Agglomeration, breakup, and forced mixing

[0043] High-speed crushing: The drive motor 24 drives the bevel gear 3 23 to rotate, which in turn drives the bevel gear 22 to rotate. The rotating bevel gear 22 drives the bevel gear 1 21 to rotate, which in turn drives the connecting shaft tube 15 to rotate. The grinding block 14 at the top of the connecting shaft tube 15 performs high-speed shearing and impact on the powdery raw material inside the conical shell 10, thoroughly crushing the agglomerates.

[0044] Spiral mixing and wall scraping: The spiral blades 17 on the connecting shaft tube 15 push the material up and down, while the scraper 16 rotates close to the inner wall of the weighing barrel 9 to remove adhering residues, eliminate mixing dead corners, and improve the mixing uniformity by more than 40%.

[0045] 4. Integrated material discharge and cleaning

[0046] Sealed discharge: The mixed material is discharged through the discharge valve 7 at the bottom of the weighing tank 9. The valve adopts a threaded sealing design to prevent leakage.

[0047] Self-cleaning function: After discharge, the drive motor 24 maintains low-speed operation, and the scraper 16 and spiral blade 17 automatically clean the residual material in the weighing bucket 9, reducing the frequency of manual cleaning.

[0048] 5. Protection treatment

[0049] When the material enters the weighing tank 9, protective gas can be introduced into the connecting pipe 20 through the connecting pipe 19. The gas will then enter the connecting pipe 29 and then the connecting shaft pipe 15. It will then be sprayed out from the bottom of the connecting shaft pipe 15 to protect the material from crushing and stirring inside the tank 3. The gas will then be discharged from the exhaust pipe 18.
