Description

Technical Field

[0001] This utility model relates to the field of dispersion mixer technology, and in particular to a dual planetary dispersion mixer for epoxy resin composites. Background Technology

[0002] A dispersing mixer, also known as a mixer, is an industrial device that mixes materials by rotating a bladed shaft in a cylinder or trough. Main types include forced-drive, single-shaft, and twin-shaft mixers. The core components of this equipment are made of stainless steel and are driven by three motors. The main agitator revolves around a central axis, while the other two agitators rotate on their own axis and revolve around the central axis, respectively. A mountain-shaped scraper at the bottom of the vessel ensures thorough mixing without dead zones.

[0003] When existing dual planetary dispersers are used for high-speed mixing of epoxy resin composites, the high viscosity and easy seepage of the materials mean that conventional flat seals or O-ring seals are prone to leaks and incomplete sealing during frequent start-stop and rapid lifting operations. In addition, common splash guards are complex and inconvenient to disassemble and assemble, which seriously affects production efficiency. Especially in industrial scenarios that require frequent feeding, cleaning and replacement of mixing tanks, how to achieve a sealing connection that is both fast and convenient and absolutely reliable has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides a dual planetary dispersion mixer for epoxy resin composites.

[0005] The technical solution adopted in this utility model is as follows: a double planetary dispersion mixer for epoxy resin composites, comprising a double planetary mixer body and a mixing tank for storing materials. A feeding protective cylinder is provided on the lifting seat of the double planetary mixer body, located directly above the mixing tank. A sealing connection assembly is provided between the bottom end of the feeding protective cylinder and the top end of the mixing tank. The sealing connection assembly includes a bottom connecting ring located at the top of the mixing tank, with a W-shaped sealing connecting block at the top. A top connecting ring corresponding to the bottom connecting ring is provided at the bottom end of the feeding protective cylinder, with a sealing connecting groove matching the sealing connecting block at the bottom end. A sealing gasket is embedded in the inner wall of the sealing connecting block, forming a dual sealing structure of metal centering and elastic sealing. A supporting base plate is provided at the bottom end of the double planetary mixer body, and a positioning assembly for positioning the mixing tank is provided on the double planetary mixer body. A discharge pipe is provided at the bottom end of the mixing tank, and an electromagnetic control valve is installed on the discharge pipe.

[0006] Preferably, the positioning component includes a base located at the top of the supporting base plate, and the hydraulic lifting component of the dual planetary mixer body is embedded at the top of the base.

[0007] Preferably, a positioning plate is provided on one side of the base, the positioning plate is provided with a positioning arc groove that matches the mixing tank, and one end of the positioning plate is connected to a reinforcing slide plate that matches the positioning arc groove via a pin.

[0008] Preferably, the end of the positioning plate is provided with a positioning groove, the end of the reinforcing slide plate is provided with a positioning block that matches the positioning groove, a spring pin is embedded in the positioning block, and a positioning hole that communicates with the positioning groove and matches the pin of the spring pin is opened on the positioning plate.

[0009] Preferably, the feeding protective cylinder is connected to an upwardly inclined feeding pipe, and the top end of the feeding pipe is provided with a flange.

[0010] Preferably, the bottom of the mixing tank is equipped with multiple foot brake casters.

[0011] The beneficial effects of this utility model are as follows: With the provided sealing connection assembly, after the feeding protective cylinder descends, the sealing connection groove at the bottom of the top connecting ring matches and engages with the sealing connection block at the top of the bottom connecting ring. The sealing connection block is W-shaped, effectively solving the problem of creeping and leakage of high-viscosity epoxy resin during the stirring process. The W-shaped sealing structure, through its multi-peak staggered design, extends the leakage path and simultaneously achieves dual protection through both a hard metal seal and an elastic soft seal.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0019] like Figures 1-4As shown, this embodiment provides a dual planetary dispersion mixer for epoxy resin composites, including a dual planetary mixer body 1 ("dual planetary" refers to the mixer having two agitators that move like planets, achieved by two transmission systems; the two agitators (usually a dispersion disc and a multi-tooth scraper) are mounted on a common revolution frame (or rotating arm), driven by a main motor, causing the two agitators to rotate on a large scale around the central axis of the mixing tank, called revolution; while the revolution frame drives them to rotate around the center of the tank, each agitator also rotates at high speed around its own axis, called rotation) and a mixing tank 2 for storing materials. The lifting seat of the dual planetary mixer body 1 is equipped with a feeding protective cylinder 3 located directly above the mixing tank 2. The feeding protective cylinder 3 is fixed to the lifting seat via a flange connection, ensuring that it remains vertically aligned during lifting and lowering, preventing skewing. To address the uneven sealing issue, a sealing connection assembly 4 is provided between the bottom end of the feeding protective cylinder 3 and the top end of the mixing tank 2. The sealing connection assembly 4 includes a bottom connecting ring 5 located at the top end of the mixing tank 2, a sealing connection block 6 with a W-shaped cross-section at the top end of the bottom connecting ring 5, a top connecting ring 7 corresponding to the bottom connecting ring 5 at the bottom end of the feeding protective cylinder 3, a sealing connection groove 8 matching the sealing connection block 6 at the bottom end of the top connecting ring 7, and a sealing gasket 9 embedded in the inner wall of the sealing connection block 6, forming a dual sealing structure of metal centering and elastic sealing. The bottom of the main body 1 of the double planetary mixer is provided with a supporting base plate 10. The main body 1 of the double planetary mixer is provided with a positioning component 11 for positioning the mixing tank 2. The bottom of the mixing tank 2 is provided with a discharge pipe 23, and an electromagnetic control valve 24 is installed on the discharge pipe 23. Through the provided sealing connection component 4, after the feeding protective cylinder 3 descends, the sealing connection groove 8 at the bottom of the top connecting ring 7 matches and engages with the sealing connection block 6 at the top of the bottom connecting ring 5. The sealing connection block 6 is designed in a W shape, which effectively solves the problem of creeping and leakage of high viscosity epoxy resin during the mixing process. The W-shaped sealing structure, through its multi-peak staggered design, extends the leakage path and provides dual protection through both a hard metal seal and an elastic soft seal. This ensures centering and provides a continuous and stable sealing pressure. Combined with the sealing gasket 9, it ensures an extremely high level of sealing between the feeding protection cylinder 3 and the mixing tank 2. This prevents liquid materials from leaking out from the connection between the feeding protection cylinder 3 and the mixing tank 2 during the material dispersion and mixing process. It also allows for quick sealing of the feeding protection cylinder 3 and the mixing tank 2, improving the connection efficiency between them.With the positioning component 11, the mixing tank 2 can be quickly positioned, achieving rapid and precise docking between the mixing tank 2 and the feeding protective cylinder 3. This greatly improves the efficiency and sealing reliability of the equipment, and further enhances the rapid connection between the feeding protective cylinder 3 and the mixing tank 2. During discharge, opening the solenoid control valve 24 allows discharge through the discharge pipe 23. The sealing connection block 6 in the sealing connection component 4 has a W-shaped cross-section, forming multiple sealing interfaces through three continuous peaks and valleys. Compared to conventional O-rings or flat seals, the W-shaped structure provides more sealing under the same compression stroke. The longer leakage path significantly improves sealing performance. The bottom connecting ring 5 and the top connecting ring 7 provide initial centering and mechanical support, while the embedded sealing gasket 9 provides elastic sealing force upon further compression, making it suitable for vibration conditions under high-speed stirring. To verify the sealing effect of the W-shaped structure, the following comparative experiments were conducted: After the sealing pressure test, the W-shaped sealing structure showed no leakage at 0.6 MPa, while the flat seal showed leakage at 0.4 MPa; after the leakage rate test, after 100 repeated connections, the leakage rate of the W-shaped seal was still below 0.01 mL / min, far superior to the 0.5 mL / min of the flat seal; after the repeated connection performance test, after 500 repeated insertion and removal tests, the W-shaped sealing structure maintained good sealing and centering, and the wear rate of the sealing gasket was less than 5%.

[0020] The positioning component 11 includes a base 12 located at the top of the supporting base plate 10, and the hydraulic lifting component of the double planetary mixer body 1 is embedded at the top of the base 12.

[0021] A positioning plate 13 is provided on one side of the base 12. The positioning plate 13 has a positioning arc groove 14 that matches the mixing tank 2. One end of the positioning plate 13 is connected to a reinforcing slide plate 15 that matches the positioning arc groove 14 via a pin. The end of the positioning plate 13 has a positioning groove 16. The end of the reinforcing slide plate 15 has a positioning block 17 that matches the positioning groove 16. A spring pin 18 is embedded in the positioning block 17. The positioning plate 13 has a positioning hole 19 that communicates with the positioning groove 16 and matches the pin of the spring pin 18. After the mixing tank 2 moves to the top of the base 12, the positioning arc groove 14 can provide a good positioning effect for the mixing tank 2. By rotating the reinforcing slide plate 15 via the pin, the positioning block 17 matches the positioning groove 16. Under the elastic force of the spring pin 18, the pin of the spring pin 18 matches the positioning hole 19, which can limit the positioning block 17.

[0022] The feeding protective cylinder 3 is connected to an upwardly inclined feeding pipe 20, and the top of the feeding pipe 20 is provided with a flange 21.

[0023] The bottom of the mixing tank 2 is equipped with multiple foot brake casters 22, which facilitates the movement of the mixing tank 2.

[0024] During operation, after the mixing tank 2 is moved to the top of the base 12 by the foot brake caster 22, the positioning groove 14 can effectively position the mixing tank 2. The pin-rotated reinforcing slide plate 15 ensures that the positioning block 17 matches the positioning groove 16. Under the elastic force of the spring pin 18, the pin of the spring pin 18 matches the positioning hole 19, thus limiting the positioning block 17. Through the provided sealing connection assembly 4, after the feeding protective cylinder 3 descends, the sealing connection groove 8 at the bottom of the top connecting ring 7 matches the sealing connection block 6 at the top of the bottom connecting ring 5. The matching snap-fit ​​design, along with the W-shaped sealing connection block 6 and the sealing gasket 9, ensures a highly airtight connection between the feeding protection cylinder 3 and the mixing tank 2. This prevents liquid materials from leaking out of the connection between the feeding protection cylinder 3 and the mixing tank 2 during the material dispersion and mixing process. It also allows for quick sealing of the feeding protection cylinder 3 and the mixing tank 2, improving the connection efficiency. The positioning component 11 allows for quick positioning of the mixing tank 2, further enhancing the rapid connection between the feeding protection cylinder 3 and the mixing tank 2.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
