DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model discloses a flame retardant polypropylene reactor, and provides two embodiments.

[0026] For example, see Figure 1-4 :

[0027] A flame-retardant polypropylene reactor comprises a base 1, a support frame 2 is fixedly connected to the upper surface of the base 1, a fixed plate 3 is fixedly connected to the side of the support frame 2 away from the base 1, a plurality of load-bearing feet 4 are fixedly connected to the upper surface of the fixed plate 3, a kettle body 5 is fixedly connected to the side of the load-bearing feet 4 away from the fixed plate 3, a heater 9 is fixedly connected to one side of the kettle body 5, and a feed port 6 is fixedly connected to one side of the kettle body 5.

[0028] In this embodiment, the preparation material of the kettle body 5 is 85 parts by weight of polypropylene particles, 5 parts by weight of flame retardant, 3 parts by weight of anti-aging agent, and 1 part by weight of high-purity graphite powder;

[0029] The steps for making the kettle body 5 in this embodiment are:

[0030] S1, the solid materials in the raw materials are physically ground and then mixed in a high-speed mixer;

[0031] S2, use ultrasonic multi-frequency vibration machine to mix the principle deeply and evenly again;

[0032] S3, melting the mixed material at high temperature, then extruding and cooling, so as to prepare a polypropylene reactor body having flame retardant properties and easy to conduct static electricity;

[0033] S4, welding the parts according to the design requirements to complete the preparation of the flame-retardant polypropylene reactor.

[0034] The kettle body 5 prepared by the raw materials and preparation steps in the above embodiment has good flame retardancy, is safe and reliable during use, and avoids unnecessary industrial accidents.

[0035] The top of the kettle body 5 is fixedly connected with an active stirring component for uniformly stirring the inside of the barrel, and the active stirring component penetrates and extends to the inside of the kettle body 5 .

[0036] In addition, the active stirring component includes an explosion-proof motor 7 arranged on the top of the kettle body 5. The output shaft of the explosion-proof motor 7 is coaxially connected to a barrel stirring frame 8 with one end passing through and extending into the interior of the kettle body 5. The barrel stirring frame 8 is composed of a rotating rod and stirring blades. The output shaft of the explosion-proof motor 7 is coaxially connected to a rotating rod with one end passing through and extending into the interior of the kettle body 5. A plurality of stirring blades are fixedly connected to the outer side of the rotating rod.

[0037] It should be understood in this embodiment that the plurality of stirring blades do not contact the auxiliary mixing assembly, so no collision occurs during the rotation process.

[0038] An auxiliary mixing component for enhancing the mixing and stirring effect is fixedly connected to the center of the upper surface of the base 1 , and the auxiliary mixing component penetrates and extends to the interior of the kettle body 5 .

[0039] It should be noted that in the above embodiment, the auxiliary mixing assembly includes a servo-controlled motor 10 arranged on the upper surface of the base 1, and the output shaft of the servo-controlled motor 10 is coaxially connected to a rotating shaft 11 at one end of which passes through the fixed disk 3 and the kettle body 5 in sequence and extends to the inside of the kettle body 5. The top of the rotating shaft 11 is fixedly connected to a rotating disk 12, and the top of the rotating disk 12 is fixedly connected to a plurality of multi-leaf mixing racks 13. The number of the multi-leaf mixing racks 13 is multiple, and the plurality of multi-leaf mixing racks 13 are symmetrically and equidistantly distributed around the midpoint of the rotating disk 12 as the symmetrical point.

[0040] Among them, the multi-blade mixing frame 13 is composed of a rotating column and stirring blades. The top of the rotating disk 12 is fixedly connected to the rotating column, and the outer side of the rotating column is fixedly connected to a plurality of stirring blades. By setting the rotating column and arranging multiple stirring blades on the outer side, the rotating disk 12 can drive the rotating column and the stirring blades to rotate in a ring around the stirring frame 8 in the barrel with the midpoint of the rotating disk 12 as the axis when rotating, thereby enhancing the mixing effect and reducing the dead zone generated during stirring.

[0041] The working principle of this embodiment is as follows:

[0042] The explosion-proof motor 7 is started to drive the stirring frame 8 in the barrel to rotate clockwise to mix the raw materials, and then the servo control motor 10 is started to drive the rotating shaft 11 and the multi-leaf mixing frame 13 to rotate counterclockwise. Since there are multiple stirring blades in the multi-leaf mixing frame 13, excessive stirring dead zones can be avoided during the rotation process. Moreover, since the stirring direction is opposite to that of the stirring frame 8 in the barrel, the centrifugal force of the fluid generated can also further improve the mixing efficiency.

[0043] For example 2, please refer to Figure 1-3 and Figure 5 The top of the rotating disk 12 is fixedly connected with a plurality of multi-leaf elastic collision frames 14, and the multi-leaf elastic collision frames 14 are composed of a connecting frame and a heat-insulating rubber sheet. A plurality of heat-insulating rubber sheets are arranged on the outer side of the connecting frame, and the rest is the same as the first embodiment.

[0044] It should be noted that in this embodiment, the thermal insulation rubber sheet is made of silicone rubber, which has good heat resistance and excellent elasticity, and can be effectively deformed when in contact without the phenomenon of rigid contact.

[0045] It should also be noted that the positions of the heat insulating rubber sheets in the multi-leaf elastic collision frame 14 are staggered with the positions of the stirring blades in the stirring frame 8 in the barrel.

[0046] In this embodiment, the preparation material of the kettle body 5 is 95 parts by weight of polypropylene particles, 10 parts by weight of flame retardant, 5 parts by weight of anti-aging agent, and 3 parts by weight of high-purity graphite powder;

[0047] The manufacturing steps of the kettle body 5 in this embodiment are the same as those in the first embodiment.

[0048] The working principle of this embodiment is as follows:

[0049] The working principle of this embodiment is basically the same as that of the first embodiment, with the difference being that the multi-leaf mixing frame 13 is replaced by a multi-leaf elastic collision frame 14. Since the position of the heat-insulating rubber sheet in the multi-leaf elastic collision frame 14 is staggered with the position of the stirring blades in the stirring frame 8 in the barrel, and the heat-insulating rubber sheet has elasticity, it will continuously collide with the stirring frame 8 in the barrel and deform during rotation. During the deformation process, the surrounding fluid will be affected by the impact force, thereby improving the flow performance and enhancing the mixing effect.

[0050] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
