Description

Technical Field

[0001] This application relates to the field of internal mixing technology, and in particular to an internal mixing apparatus for the preparation of rare earth brightening agent masterbatch. Background Technology

[0002] Rare earth light-converting agents are novel functional materials with light conversion capabilities, and can be widely used in fields such as fiber optic communication, agricultural films, bioanalytical sensors, and laser technology. Rare earth light-converting agent masterbatches are formed by uniformly dispersing rare earth light-converting agents into polymers such as polyolefins.

[0003] In existing technologies, rare earth brightening agent masterbatch needs to go through mixing, extrusion and granulation steps to be formed. Existing mixing equipment usually consists of a mixing chamber, a pressure plate structure and a flipping structure. The pressure plate structure is used to seal the opening of the mixing chamber, and the flipping structure is used to flip the mixing chamber so that the mixed material can be taken out from the opening. However, since the pressure plate structure does not have a temperature control structure, when the opening of the mixing chamber is sealed by the pressure plate structure, the rare earth brightening agent and polymers such as polyolefins will be heated unevenly, which will affect the quality of the final rare earth brightening agent masterbatch.

[0004] Therefore, it is necessary to propose a mixing device for the preparation of rare earth light conversion agent masterbatch, and improve the quality of rare earth light conversion agent masterbatch, which has become an important technical problem that needs to be solved urgently. Utility Model Content

[0005] This application provides a mixing apparatus for the preparation of rare earth brightening agent masterbatch, which aims to solve the problem in the prior art that, due to the lack of a temperature control structure in the pressure plate structure, the opening of the mixing chamber is blocked by the pressure plate structure, resulting in uneven heating of rare earth brightening agent and polymers such as polyolefins, which affects the quality of the final rare earth brightening agent masterbatch.

[0006] To achieve the above objectives, this application proposes a mixing apparatus for preparing rare earth light conversion agent masterbatch, comprising: a frame; a mixing chamber with an opening, the mixing chamber being rotatably mounted on the frame; a jacket with an outer side of the mixing chamber, the jacket and the mixing chamber enclosing a first temperature-controlled space; a pressure chamber adapted to the opening of the mixing chamber, the pressure chamber having a second temperature-controlled space inside; and a pressure drive mounted on the frame, the output end of the pressure drive being connected to the pressure chamber.

[0007] In some embodiments, the device further includes: a first temperature control inlet, which is provided on the jacket and connects to a first temperature control space; a first temperature control outlet, which is provided on the jacket and connects to the first temperature control space; a second temperature control inlet, which is provided on the pressure chamber and connects to a second temperature control space; and a second temperature control outlet, which is provided on the pressure chamber and connects to the second temperature control space.

[0008] In some embodiments, the system further includes: a first reinforcing plate disposed within a first temperature control space; and a second reinforcing plate disposed within a second temperature control space.

[0009] In some embodiments, the system further includes a hydraulic station, which is mounted on the frame.

[0010] In some embodiments, the device further includes a mounting platform on which the rack is mounted.

[0011] In some embodiments, the device further includes a high-temperature resistant seal, wherein the opening is provided with a high-temperature resistant seal.

[0012] This application proposes a mixing apparatus for preparing rare earth color-converting agent masterbatch, comprising: a frame; a mixing chamber with an opening, rotatably mounted on the frame; a jacket surrounding the mixing chamber, the jacket and the mixing chamber enclosing a first temperature-controlled space; a pressure chamber adapted to the opening of the mixing chamber, with a second temperature-controlled space inside; and a pressure drive mounted on the frame, its output connected to the pressure chamber. The pressure drive moves the pressure chamber upwards, opening the opening of the mixing chamber, allowing the rare earth color-converting agent and polymers such as polyolefins to be introduced into the mixing chamber. At this point, the pressure drive moves the pressure chamber upwards again, sealing the opening of the mixing chamber, and initiating mixing to fully disperse the rare earth color-converting agent into the polymers such as polyolefins. During the mixing process, the temperature inside the sealed mixing chamber is precisely controlled by the continuously circulating temperature-controlled liquid in the first and second temperature-controlled spaces. This allows the temperature of each structure in contact with the rare earth brightener and polyolefin polymers to become more uniform, ensuring that the rare earth brightener and polyolefin polymers are heated evenly, thereby improving the quality of the final rare earth brightener masterbatch.

[0023] See Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this application proposes a mixing apparatus for preparing rare earth light conversion agent masterbatch, comprising: a frame 1; a mixing chamber 12, the mixing chamber 12 having an opening and being rotatably mounted on the frame 1; a jacket 13, the jacket 13 being provided on the outside of the mixing chamber 12, the jacket 13 and the mixing chamber 12 enclosing a first temperature control space; a pressure chamber 8, the pressure chamber 8 being adapted to the opening of the mixing chamber 12, the pressure chamber 8 having a second temperature control space 9 inside; and a pressure drive 6, the pressure drive 6 being mounted on the frame 1, the output end of the pressure drive 6 being connected to the pressure chamber 8.

[0024] Rare earth light-converting agent masterbatch is produced by uniformly dispersing rare earth light-converting agents into polymers such as polyolefins through mixing and extrusion equipment, and finally granulating them using a granulator to form rare earth light-converting agent masterbatch. Rare earth light-converting agent masterbatch is an important production material for light-converting agricultural films, whose main function is to convert ultraviolet and green light in sunlight into red-orange and blue light beneficial to plant growth. In agricultural production, it can significantly improve the yield and quality of crops.

[0025] Among them, frame 1 is the structural basis of the internal mixing device for preparing rare earth brightening agent masterbatch, and other structures on the internal mixing device for preparing rare earth brightening agent masterbatch are directly or indirectly connected to frame 1.

[0026] The mixing chamber 12 contains a mixing cavity, and two rotors 15 are rotatably mounted within it. The minimum gap between the rotors 15 and the inner wall of the mixing chamber 12 is 3mm, used for squeezing and shearing materials to ensure that the rare earth brightening agent is uniformly dispersed in polymers such as polyolefins. The mixing device also includes a rotor drive, a reduction transmission structure 17, and a tilting cylinder 16, used to realize the rotation of the rotors 15 and the tilting function of the mixing chamber 12. The rotor drive, reduction transmission structure 17, tilting cylinder 16, and the corresponding tilting structure are mature existing technologies. For details, please refer to patent-202010238893.9-Improved Tilting System, Feeding Device and Method of Internal Mixer. Of course, other mature existing technologies can also be referenced. This application does not impose specific limitations on the rotor drive, reduction transmission structure 17, tilting cylinder 16, and the corresponding tilting structure.

[0027] The jacket 13 and the pressure chamber 8 are the core structures of this application. The temperature-controlled liquid is discharged into the first temperature-controlled space to precisely control the temperature within the mixing chamber 12. The temperature-controlled liquid can also enter the second temperature-controlled space 9 within the pressure chamber 8, which facilitates precise temperature control within the sealed mixing chamber 12 and ensures that the temperatures of various structures in contact with the rare earth brightener and polyolefins are more uniform, resulting in even heating of the rare earth brightener and polyolefins. The pressure drive 6 is a hydraulic cylinder, whose output end is connected to the pressure chamber 8.

[0028] Specifically, the pressure drive 6 moves the pressure chamber 8 upward, opening the opening of the mixing chamber 12, and allowing the rare earth brightener and polymers such as polyolefins to be added into the mixing chamber 12. At this time, the pressure drive 6 moves the pressure chamber 8 upward, sealing the opening of the mixing chamber 12, and the mixing process begins, ensuring the rare earth brightener is fully dispersed into the polymers such as polyolefins. During the mixing process, the temperature inside the sealed mixing chamber 12 is precisely controlled by the continuously circulating temperature-controlled liquid in the first and second temperature-controlled spaces 9. This ensures that the temperature of all components in contact with the rare earth brightener and polymers is consistent, resulting in uniform heating of the rare earth brightener and polymers, thereby improving the quality of the final rare earth brightener masterbatch.

[0029] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, it further includes: a first temperature-controlled inlet, which is provided on the jacket 13 and connects to a first temperature-controlled space; the first temperature-controlled inlet is connected to a temperature-controlled liquid inflow pipe via a hose 4; and a first temperature-controlled outlet, which is provided on the jacket 13 and connects to the first temperature-controlled space; the first temperature-controlled outlet is connected to a temperature-controlled liquid outflow pipe via a hose 4. The temperature-controlled liquid inflow pipe is connected to a temperature-controlled liquid source. The temperature-controlled liquid in the temperature-controlled liquid source flows into the first temperature-controlled space from the temperature-controlled liquid inflow pipe. The temperature-controlled liquid absorbs or releases heat to control the temperature of the mixing chamber 12. After absorbing or releasing heat, the temperature-controlled liquid flows into the temperature-controlled liquid outflow pipe from the first temperature-controlled outlet and passes through a heat exchanger or heater to readjust the temperature of the temperature-controlled liquid. The temperature-controlled liquid restored to its initial temperature can flow back into the temperature-controlled liquid source to form a temperature-controlled liquid circulation. A second temperature-controlled inlet is provided on the pressurization chamber 8, and the second temperature-controlled inlet connects to the second temperature-controlled space 9; a second temperature-controlled outlet is provided on the pressurization chamber 8, and the second temperature-controlled outlet connects to the second temperature-controlled space 9. The flow pattern of the temperature-controlled liquid in the second temperature-controlled space 9 is the same as that in the first temperature-controlled space, and will not be repeated here.

[0030] In this embodiment, the two ends of the hose 4 are heated and flared to fit onto the first temperature-controlled inlet, the first temperature-controlled outlet, the temperature-controlled liquid inflow pipe, or the temperature-controlled liquid outflow pipe. After the two ends of the hose 4 cool, they are tightened with clamps. A hot flow pump 18 and a cold flow pump 19 are installed on the frame 1, and a temperature probe is installed on the mixing chamber 12. The temperature probe is a mature existing technology, and its specific structure is not limited here. The hot flow pump 18 or the cold flow pump 19 is driven by judging the temperature inside the mixing chamber 12, so as to stably control the temperature of the mixing chamber 12 and the pressurization box 8. Corresponding valve bodies are installed on the temperature-controlled liquid inflow pipe and the temperature-controlled liquid outflow pipe, and the structures of the temperature-controlled liquid inflow pipe, the temperature-controlled liquid outflow pipe, and the valve bodies that constitute the temperature control system are all mature existing technologies, and their structures are not specifically limited here.

[0031] See Figure 1 and Figure 2 As shown, in some embodiments, the system further includes: a first reinforcing plate 14 disposed within a first temperature control space; and a second reinforcing plate 10 disposed within a second temperature control space 9. The first reinforcing plate 14 enhances the strength of the jacket 13, and the second reinforcing plate 10 enhances the strength of the pressure chamber 8. Furthermore, the second reinforcing plate 10 and the first reinforcing plate 14 increase the heat exchange area with the temperature-controlled liquid, thereby increasing the temperature control efficiency. Preferably, the second reinforcing plates 10 are arranged at a high density within the second temperature control space 9 to ensure that the strength of the pressure chamber 8 meets design requirements.

[0032] See Figure 1 and Figure 4 As shown, it also includes a hydraulic station, which is installed on the frame 1. The pressure drive 6 is a hydraulic cylinder, inside which an output rod 3 is movably installed. The hydraulic station controls the extension or retraction of the output rod 3 through hydraulic oil. The hydraulic station and its control system for the hydraulic cylinder are mature existing technologies, and their structure will not be specifically limited here. A lead screw guard 2 is installed on the outside of the output rod 3 to protect the output rod 3. The output rod 3 is connected to the pressure box 8 through fasteners such as locking nuts.

[0033] See Figure 1 and Figure 3 As shown, in some embodiments, the system further includes a mounting platform 7 on which the frame 1 is mounted. The frame 1 is mounted to the mounting platform 7 using fasteners such as screws to ensure the stability of the frame 1.

[0034] See Figure 1 and Figure 2As shown, in some embodiments, it further includes a high-temperature resistant seal 11, which is provided on the opening. The mixing chamber 12 is provided with a high-temperature resistant seal 11 at the opening, and in the closed state, the high-temperature resistant seal 11 improves the sealing performance between the pressure box 8 and the opening of the mixing chamber 12.

All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
