Description

Technical Field

[0001] The invention relates to the technical field of flame retardant production, in particular to a brominated triazine flame retardant material mixing device. Background Art

[0002] Brominated triazine flame retardant is a new type of bromine / nitrogen synergistic flame retardant with excellent resistance to ultraviolet radiation and light resistance. It overcomes the shortcomings of tetrabromo and decabromo flame retardants such as poor light resistance and easy yellowing. It is an upgraded alternative product to tetrabromo and decabromo flame retardants.

[0003] In the process of making brominated triazine flame retardant, brominated triazine powder needs to be mixed with solvent to improve its thermal stability, anti-aging performance and flame retardant effect. Most of the existing mixing technologies are to put brominated triazine powder and solvent into a mixing barrel in proportion, and stir and mix them by a pitched blade stirrer. In order to increase the mixing reaction rate, the mixing barrel can heat the solution to a suitable temperature. However, due to the fact that the molecular structure of brominated triazine may be large, and the presence of bromine atoms may make it less soluble in certain solvents or substrates, and the pitched blade stirrer in the existing mixing equipment has a greater speed when the stirring blade is farther away from the rotating shaft, the solution exchange efficiency near the rotating shaft is lower than the solution exchange efficiency far from the rotating shaft, and the mixing effect of the solution within the same height range is inconsistent, which makes the mixing method single, and the solution at different positions is difficult to exchange effectively, which also leads to low heat transfer efficiency. Therefore, during mixing, brominated triazine may be difficult to be evenly dispersed in the substrate, resulting in the flame retardant effect of the flame retardant product being not uniform.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] like Figure 1-Figure 10As shown together, this embodiment provides a brominated triazine flame retardant material mixing device, which includes a mixing barrel 1, the mixing barrel 1 is tilted, and a plurality of stirring blades 2 are evenly distributed on the inner wall of the mixing barrel 1. A heating mechanism is axially arranged in the mixing barrel 1, and a support frame 3 is arranged at the lower side of the mixing barrel 1. The support frame 3 is used to provide rotation support for the mixing barrel 1 and the heating mechanism. A driving mechanism 4 is installed on the support frame 3, and the driving mechanism 4 is used to drive the mixing barrel 1 to rotate; the heating mechanism includes a heating component 5 rotatably connected to the mixing barrel 1, and an air intake component 6 and an aeration component 6 are respectively arranged at both ends of the heating component 5. Part 7, the aeration component 7 is arranged at the bottom of the mixing barrel 1; the heating component 5 includes a heating tube 51 rotatably connected to the bottom of the mixing barrel 1, and a heating element is installed in the heating tube 51. The air intake component 6 includes an air intake cylinder 61 fixedly connected to the upper end of the heating tube 51, and a piston component 62 is slidably connected in the air intake cylinder 61. One end of the air intake cylinder 61 extends to the outside of the mixing barrel 1 and is fixedly installed with an electric push rod 63. The electric push rod 63 is used to drive the piston component 62 to move. The aeration component 7 includes an aeration plate 71, and the aeration plate 71 is connected to the heating tube 51 through a plurality of connecting tubes 72, and a plurality of aeration units 73 are provided on the aeration plate 71.

[0034] In the above technical solution, when the driving mechanism 4 drives the inclined mixing barrel 1 to rotate, the bromotriazine powder and the solvent rotate and mix with the rotation of the mixing barrel 1 and the stirring blade 2, and the heating element can heat the heating tube 51 to the working temperature. The electric push rod 63 drives the piston 62 to reciprocate, and intermittently introduces air into the heating tube 51 through the air intake cylinder 61. The air is heated in the heating tube 51. When the air intake cylinder 61 introduces air into the heating tube 51 again, the pressure in the heating tube 51 increases, and part of the hot air enters the aeration plate 71 through the connecting pipe 72. After passing through the aeration unit 73, small bubbles are formed. The bubbles float at the bottom of the mixing barrel 1, which makes the solution move, prompting the bromotriazine powder and the solvent to move in multiple directions to improve the uniform dispersion effect. At the same time, when the bubbles are dispersed in the solution, the heat can be effectively absorbed by the solution, so that the solution is quickly heated to the optimal reaction temperature.

[0035] Among them, refer to Figure 5 The shell of the heating tube 51 presents a cavity structure, and the heating element is installed in the cavity. When the heating element heats the heating tube 51, on the one hand, the air in the heating tube 51 is heated, and on the other hand, the outer wall of the heating tube 51 is in direct contact with the solution, and the solution can be directly preliminarily heated.

[0036] The stirring blade 2 is connected and fixed to the inner wall of the mixing barrel 1, and the stirring blade 2 has a spiral structure. Figure 4When the mixing barrel 1 rotates, the stirring blade 2 drives the solution on the edge of the mixing barrel 1 to flip quickly. At the same time, since the mixing barrel 1 is tilted, when the stirring blade 2 rotates to the upper side, part of the solution remaining on the stirring blade 2 can flow downward along the inclined surface of the stirring blade 2, thereby bringing part of the solution in the bottom of the mixing barrel 1 to the upper side, thereby improving the mixing method of the solution.

[0037] The one-way air inlet valve 52 is fixedly connected to the end of the heating tube 51 close to the air inlet cylinder 61. The one end of the heating tube 51 close to the bottom of the mixing barrel 1 is rotatably connected to the mixing barrel 1 through the second bearing 8. The one end of the air inlet cylinder 61 away from the mixing barrel 1 is rotatably connected to the mixing barrel 1 through the third bearing 9. Figure 4 and Figure 5 The one-way air intake valve 52 allows the gas in the air intake cylinder 61 to move only into the heating tube 51, preventing the heated air in the heating tube 51 from overflowing and causing heat loss. The axis of the heating tube 51 and the air intake cylinder 61 coincide with the axis of the mixing barrel 1. The heating tube 51 and the air intake cylinder 61 cooperate to support the mixing barrel 1 for rotation, so that the mixing barrel 1 rotates around the heating tube 51 as the axis.

[0038] Among them, refer to Figure 3 , Figure 4 The mixing barrel 1 consists of a barrel body 11 and a barrel cover 12 connected thereto. A feed port is provided on the barrel cover 12, and a sealing cover 13 is threadedly connected to the feed port. A discharge pipe 14 is fixedly installed at the bottom of the barrel body 11, and a switch valve is installed on the discharge pipe 14. The second bearing 8 is used to connect the heating pipe 51 and the barrel body 11, and the third bearing 9 is used to connect the air inlet cylinder 61 and the barrel cover 12.

[0039] The piston member 62 includes a piston plate 621 slidably connected to the air inlet cylinder 61, a plurality of through holes 622 are provided on the piston plate 621, a connecting shaft 624 is slidably connected to the middle of the piston plate 621, and a limiting plate 625 is provided on the side of the piston plate 621 away from the electric push rod 63, and a sealing plate 626 is provided on the side of the piston plate 621 close to the electric push rod 63, and the limiting plate 625 and the sealing plate 626 are both connected and fixed to the connecting shaft 624; the sealing plate 626 is a truncated cone structure, and a sealing groove 623 adapted to the sealing plate 626 is provided on the side of the piston plate 621 facing the sealing plate 626, refer to Figure 6 and Figure 7 When the connecting shaft 624 descends, the sealing plate 626 abuts against the sealing groove 623, so that the through hole 622 is blocked. When the piston plate 621 descends, the air in the air intake cylinder 61 is pushed into the heating tube 51. When the connecting shaft 624 rises, it drives the sealing plate 626 to leave the sealing groove 623, and then the limit plate 625 abuts against the bottom of the piston plate 621. At this time, the through hole 622 connects the air intake cylinder 61 with the outside world, allowing air to enter the air intake cylinder 61.

[0040] It can be understood that in order to enable the piston member 62 to move stably in the air intake cylinder 61, a plurality of vertical protrusions are fixedly provided on the inner wall of the air intake cylinder 61, and grooves matching the vertical protrusions are opened on the edge of the piston plate 621. In addition, a guide frame is fixedly connected to the upper end of the air intake cylinder 61, and the connecting shaft 624 is slidably set on the guide frame.

[0041] The end of the air inlet cylinder 61 away from the heating tube 51 is fixedly connected to the fixing frame 64, and the electric push rod 63 is fixedly installed on the fixing frame 64, and one end of the electric push rod 63 is fixedly connected to the connecting shaft 624. Figure 6 When the electric push rod 63 extends and contracts, it drives the connecting shaft 624 to move synchronously, so that the piston member 62 slides back and forth in the air intake cylinder 61, thereby intermittently adding air to the heating tube 51.

[0042] The aeration plate 71 is of inferior arc structure, and a plurality of aeration units 73 are evenly distributed on the side of the aeration plate 71 facing the heating tube 51; the aeration unit 73 includes an aeration tube 731 fixedly connected to the aeration plate 71, a sealing ring 732 is fixedly connected inside the aeration tube 731, and a rubber sheet 733 is abutted on the side of the sealing ring 732 away from the aeration plate 71, as shown in FIG. Figure 4 , Figure 8 , Fig.10 The aeration plate 71 is arranged in an arc shape, and its center is located on the axis of the heating tube 51, so that the obstruction of the solution to the solution when it rotates in the mixing barrel 1 can be reduced, so that the solution can be effectively rotated and mixed in the mixing barrel 1, and the rubber sheet 733 abuts against the sealing ring 732. When the air pressure value in the heating tube 51 reaches a certain level, the air pressure can drive the edge of the rubber sheet 733 to cancel the contact of the sealing ring 732, and the excess air pressure in the heating tube 51 is discharged through the upper end of the aeration tube 731 in the form of bubbles. The bubbles move upward at the bottom of the mixing barrel 1, which can promote the movement of the solution, so that the bromotriazine powder is evenly dispersed in the solvent. At the same time, the heat is absorbed by the solution, so that the solution is quickly heated to the optimal reaction temperature.

[0043] It can be understood that when the mixing barrel 1 rotates, the solution rotates centrifugally with the axis of the mixing barrel 1 as the center, and at the same time, when the bubbles rise in the solution, they drive the surrounding solution to move upward, so that the solution moves in different directions, which can improve the uniform distribution of the bromotriazine powder in the solvent.

[0044] The support frame 3 includes a bottom plate 31, a first bearing 32 is hinged on one side of the bottom plate 31, the inner ring of the first bearing 32 is connected and fixed to the lower end of the mixing barrel 1, and a support seat 33 is hinged on the other side of the bottom plate 31. A lifting frame 34 is slidably connected to the support seat 33, and the lifting frame 34 is connected and fixed to the air inlet cylinder 61; a hydraulic cylinder 35 is fixedly installed on the support seat 33, and one end of the hydraulic cylinder 35 is connected and fixed to the lifting frame 34, refer to Figure 2The first bearing 32 is used to support and limit the bottom of the mixing barrel 1 for rotation, and the support seat 33 cooperates with the lifting frame 34 to support and limit the upper end of the air inlet cylinder 61 for rotation, so that the mixing barrel 1 is placed in an inclined state, so that the mixing barrel 1 can more conveniently drive the solution to rotate when it rotates. The inclination angle of the mixing barrel 1 can be controlled by lifting and lowering the hydraulic cylinder 35, so that the solution in the mixing barrel 1 changes direction when it rotates, which can further improve the mixing effect.

[0045] The driving mechanism 4 includes a motor 41 fixedly mounted on the bottom plate 31, the output end of the motor 41 is fixedly connected to a driving gear 42, the driving gear 42 is meshed with a transmission gear 43, and the transmission gear 43 is fixedly connected to the mixing barrel 1, refer to Figure 2 The diameter of the driving gear 42 is smaller than that of the transmission gear 43. When the motor 41 drives the driving gear 42 to rotate, the mixing barrel 1 can be quickly driven to rotate through the meshing of the driving gear 42 and the transmission gear 43.

[0046] It can be understood that the first bearing 32 is connected to the base plate 31 through a hinge seat, and the connecting axis of the first bearing 32 and the hinge seat and the contact surface of the driving gear 42 and the transmission gear 43 are located on the same axis. When the angle of the mixing barrel 1 changes, the driving gear 42 and the transmission gear 43 always maintain an effective meshing transmission state.

[0047] Among them, the heating element, the hydraulic cylinder 35, the motor 41, and the electric push rod 63 are all connected to the external control module signal, and the opening and closing of each device can be controlled by the control module.

[0048] like Fig.10 As shown, a conical block 734 is provided in one end of the aeration tube 731 away from the aeration plate 71, and the conical block 734 is fixedly connected to the rubber sheet 733, and a plurality of separators 735 are fixedly connected between the conical block 734 and the aeration tube 731; a liquid inlet is provided on the aeration tube 731, and two guide plates 736 are fixedly connected to the outer side of the liquid inlet, and an inclined guide plate 737 is fixedly connected to the inner side of the liquid inlet, and the liquid inlet faces the direction of rotation of the solution, and the guide plates 736 on both sides are used to guide more solution into the aeration tube 731, and the solution pushes the discharged bubbles to move toward the upper end of the aeration tube 731, and the bubbles are cut when passing through the separator 735, so that the bubbles discharged from the aeration plate 71 form denser bubbles after being cut, thereby increasing the contact range with the solution, reducing the floating speed, and increasing the contact time between the bubbles and the solution, thereby further improving the heating effect and mixing effect of the solution.

[0049] Among them, the upper end of the aeration tube 731 is in a truncated cone shape, and the upper end of the aeration tube 731 cooperates with the conical block 734 and the partition sheet 735 to form a plurality of spaces of the same size, so that the bubbles formed by the division are of similar size, which helps to improve the contact effect between the bubbles and the solution. In addition, the setting of the guide plate 737 can prevent the solution from exerting pressure on the rubber sheet 733 when flowing into the aeration tube 731, making it difficult for the bubbles to be discharged.

[0050] When in use, the bromotriazine powder and the solvent are mixed in proportion and poured into the mixing barrel 1 through the feed port, the motor 41 drives the mixing barrel 1 to rotate, the mixing barrel 1 and the stirring blade 2 drive the solution to rotate, the electric push rod 63 drives the connecting shaft 624 to move synchronously when it extends and contracts, when the connecting shaft 624 descends, the sealing plate 626 abuts against the sealing groove 623, so that the through hole 622 is blocked, and when the piston plate 621 descends, the air in the air inlet cylinder 61 is pushed into the heating tube 51, and the heating element heats the air in the heating tube 51, and when the air in the heating tube 51 When the pressure reaches a certain level, the pressure pushes the edge of the rubber sheet 733 to cancel the contact of the sealing ring 732, and the excess air pressure in the heating tube 51 is discharged through the upper end of the aeration tube 731 in the form of bubbles. When the bubbles pass through the separator 735, they are cut to form denser bubbles. When the bubbles float up in the solution, they drive the solution to move. At the same time, the heat is absorbed by the solution, so that the solution is quickly heated to the reaction temperature and the bromotriazine powder is evenly dispersed in the solvent. After mixing is completed, the equipment is stopped, and the switch valve is opened so that the solution can be discharged through the discharge pipe 14.

[0051] It should be understood that the purpose of these embodiments is only to illustrate the present invention and is not intended to limit the protection scope of the present invention. In addition, it should also be understood that after reading the technical content of the present invention, those skilled in the art can make various changes, modifications and / or variations to the present invention, and all of these equivalent forms also fall within the protection scope defined by the appended claims of this application.
