[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0030] Obviously, the described embodiments are only some embodiments of the present invention, not all 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.

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0032] In one embodiment, see Figures 1 to 3, provides a flame retardant production and processing mixer, including a main material mixing barrel 11, a turnover machine box 12, an auxiliary material adding box 13 and a secondary mixing barrel 14; also includes an equipment machine table 21, and the two ends of the table of the equipment machine table 21 are respectively provided with a material guide output box 23 and a heat supply positioning box 25, and the barrel body of the main material mixing barrel 11 is installed between the material guide output box 23 and the heat supply positioning box 25; the table of the equipment machine table 21 is also provided with a main barrel support frame 22, and the main material mixing barrel 11 is mounted on the main barrel support frame 22 and is limited by the main barrel support frame 22; the equipment machine A bottom bracket 26 is provided at the bottom of the table 21, and the turnover box 12 is mounted on the bottom bracket 26 and connected to the output end of the material guide output box 23; the auxiliary material adding box 13 is arranged on the side edge of the equipment table 21, and the inner cavity of the auxiliary material adding box 13 is provided with an inner flipping component 27, the bottom of the auxiliary material adding box 13 is connected to the output end of the turnover box 12, and the top of the auxiliary material adding box 13 is provided with a material adding rack 28; the output end of the auxiliary material adding box 13 extends downward to be connected to the secondary mixing barrel 14, and the secondary mixing barrel 14 is provided with a secondary mixing mechanism 29.

[0033] The main material mixing barrel 11 is made of stainless steel, which has good corrosion resistance and high temperature resistance, and can meet the mixing requirements of flame retardant raw materials. The main material mixing barrel 11 is connected between the material guide output box 23 and the heating positioning box 25 through a flange. The heating positioning box 25 is externally connected to a heating device for preheating the main material to improve the subsequent mixing efficiency and quality. The equipment machine 21 is a support platform for the entire main material mixing barrel 11, and the main barrel support frame 22 is used to support the main material mixing barrel 11. The main material is put into the main material mixing barrel 11 from the feeding port 24. The main material mixing barrel 11 is designed to be rotatable to achieve full mixing of the flame retardant raw materials in the barrel. The main material mixing barrel 11 is placed at an angle as a whole, and its inclination angle is accurately calculated to ensure that the mixed materials can slide smoothly into the turnover box 12. The turnover box 12 is used as a transition container before the main material and the auxiliary material are mixed. The turnover box 12 is designed with a spacious storage space to accommodate the materials that slide down from the main material mixing barrel 11. The bottom of the turnover box 12 is provided with a discharge port, which is connected to the auxiliary material adding box 13 through a pipeline to ensure that the materials can flow smoothly into the next mixing stage. In addition, the turnover box 12 can also be provided with a vibration device to assist the material to fall and prevent blockage.

[0034] The auxiliary material adding box 13 is provided with an internal turning component 27, which is driven by a motor and turns the main material through rotating blades and operates. The auxiliary material adding box 13 is provided with a feeding rack 28, which simultaneously adds plasticizers, pH stabilizers and other auxiliary materials to the auxiliary material adding box 13. Multiple auxiliary material adding boxes 13 can be provided and connected in sequence. Each auxiliary material adding box 13 can independently control the amount and time of auxiliary material addition. The specific number of settings can be formulated according to the number of auxiliary materials and the order of addition. After the main material and the auxiliary material are initially mixed, the materials enter the secondary mixing barrel 14 for further refinement and mixing. The barrel is provided with a secondary mixing mechanism 29 to ensure the uniform distribution of the flame retardant components.

[0035] This embodiment can ensure the mixing quality, and the multi-stage mixing design is sequentially performed through the main material mixing cylinder 11, the auxiliary material adding box 13 and the secondary mixing cylinder 14, which ensures the uniform distribution and high-quality mixing of the flame retardant components. The controllable degree of mixing of the main material and the auxiliary material is improved, making the addition of the auxiliary material more accurate and efficient, avoiding production delays or quality fluctuations caused by improper addition of auxiliary materials, and realizing all-round and deep mixing from preliminary mixing to detailed mixing. This mixing method ensures a highly uniform distribution of the flame retardant components, which not only improves the performance stability of the flame retardant, but also makes the quality of the final product more excellent.

[0036] In one embodiment, see Figure 1 and Figure 2 Based on the contents of the above embodiment, the installation and implementation structure of the main material mixing barrel 11 is designed as follows:

[0037] The main barrel support frame 22 includes a machine carrier frame 61, a carrier cross plate 62 arranged on the machine carrier frame 61, and a limit ring 63 installed on the carrier cross plate 62. The main material mixing barrel 11 is limited in the limit ring 63; an outer barrel ring 67 is arranged on the outer wall of the barrel of the main material mixing barrel 11, and the outer barrel ring 67 is provided with two positions located in the front and rear of the barrel of the main material mixing barrel 11 respectively; the main barrel support frame 22 is also provided with a wing bracket 64, and the wing bracket 64 is correspondingly arranged on both sides of the outer barrel ring 67; a supporting barrel 66 is installed on the wing bracket 64 through a side drive mechanism 65; the supporting barrel 66 is a cylindrical structure and the outer barrel surface is provided with teeth; the outer ring surface of the outer barrel ring 67 is also provided with teeth, and the supporting barrel 66 is meshed with the outer barrel ring 67 through the teeth.

[0038] The construction of the main barrel support frame 22 starts with a sturdy machine support frame 61, which provides a stable base for the entire main material mixing barrel 11. On the machine support frame 61, a number of bearing cross plates 62 are fixed, and a limiting ring 63 is installed on the bearing cross plate 62. The barrel part of the main material mixing barrel 11 is limited in this limiting ring 63, ensuring the stability during the mixing process; on the outer wall of the barrel, an outer barrel ring 67 is provided at the front and rear positions. The outer barrel ring 67 not only enhances the structural strength of the barrel, but also provides a support point for the installation of the side wing bracket 64. The side wing bracket 64 is arranged on both sides of the outer barrel ring 67 and is connected to the main barrel support frame 22 by bolts and other fasteners. The design of the side wing bracket 64 takes into account the force balance to ensure that the main material mixing barrel 11 can be stably supported during the mixing process. The side drive mechanism 65 drives the support barrel 66 to rotate, and the main material mixing barrel 11 also rotates because the support barrel 66 is meshed with the tooth pattern of the outer barrel ring 67. During the rotation process, the main material is fully stirred and mixed in the barrel, thereby achieving the desired mixing effect.

[0039] In one embodiment, see Figure 1 and Figure 3 Based on the contents of the above embodiment, the internal structure of the main material mixing barrel 11 is designed as follows:

[0040] The main material mixing barrel 11 includes a main barrel shell 31, a mixing chamber 33 arranged in the inner cavity of the main barrel shell 31, and an insulation layer 32 arranged on the inner wall of the mixing chamber 33. The mixing chamber 33 is provided with a mixing roller 34, and the mixing roller 34 is provided with two sections. The two sections of the mixing roller 34 are connected by a secondary connecting sleeve 35. The heating positioning box 25 is provided with an airflow supply box 41, an air supply pipe 42 arranged in the airflow supply box 41, and an inlet pipe 44 connected to the air supply pipe 42. The shell of the heating positioning box 25 is provided with an introduction joint 43 connected to the air supply pipe 42; the heating positioning box 25 is also provided with a support kit 45, the mixing roller 34 and the secondary connecting sleeve 35 are both hollow structures, and the mounting end of the mixing roller 34 is provided with a primary connecting sleeve 46, and the primary connecting sleeve 46 and the end of the introduction joint 43 are both inserted into the sleeve of the support kit 45 and connected; a plurality of air outlet nozzles 47 are provided on the primary connecting sleeve 46 and the secondary connecting sleeve 35.

[0041] The main material mixing barrel 11 is mainly composed of a main barrel shell 31, a mixing chamber 33, an insulation layer 32, a mixing roller 34 and other parts. The main barrel shell 31, as the main structure of the main material mixing barrel 11, is made of high-strength, corrosion-resistant materials to ensure that it can withstand greater pressure and wear during the mixing process. The mixing chamber 33 is arranged in the inner cavity of the main barrel shell 31 and is the main place for mixing flame retardant materials. The shape and size of the mixing chamber 33 are reasonably designed to ensure that the flame retardant materials are fully mixed therein. The insulation layer 32 is arranged on the inner wall of the barrel of the mixing chamber 33 to isolate the influence of external heat on the temperature in the mixing chamber and maintain the stability of the mixing process.

[0042] The mixing roller 34 is provided with two sections, which are connected by a secondary connection sleeve 35 to form an integral structure. The surface of the mixing roller 34 is designed with special stirring blades to improve the mixing efficiency. For the overall mixing roller 34, one end is fixed to the support sleeve 45, and the other end is fixed to the connection end of the material guide output box 23, so it does not move with the rotation of the main cylinder shell 31, so that the static mixing roller 34 and the dynamic flame retardant material produce relative movement; the surface of the mixing roller 34 can be designed to be wavy or spiral, so as to produce dynamic turbulence or eddy current. The purpose of this design of the present embodiment is to not adopt the mixing method of high-speed rotation of the mixing roller 34, so as not to excessively increase the shear force on the material to break up the material, but not to shear and crush the material, thereby reducing the problem of cutting force destroying the molecular spacing and affecting the chemical properties. After the auxiliary materials are added later, they are mixed again in the secondary mixing barrel 14.

[0043] The flame retardant material is placed in the mixing chamber 33 of the main material mixing barrel 11. The heating device in the heating positioning box 25 is started to heat the air introduced from the outside to the required temperature. The heated hot air enters the interior of the mixing roller 34 through the air supply pipe 42, the introduction joint 43 and the primary connection sleeve 46, and is evenly distributed to the surface of the mixing roller 34 through the air outlet nozzle 47. The hot air flow diffuses with the movement of the dynamic flame retardant material and the dynamic vortex formed by the flame retardant material itself, which helps to better disperse and fuse the components in the flame retardant material, promote cross-linking and polymerization between materials, and avoid local overheating.

[0044] In one embodiment, see Figure 1 and Figure 4 Based on the contents of the above embodiment, the internal structure of the main material mixing barrel 11 is designed as follows:

[0045] The main body of the turnover machine box 12 is a bucket-shaped box 71, and a material unloading section 72 and an output pump 73 installed at the material unloading section 72 are arranged at the bottom of the bucket-shaped box 71; an introduction section 81 connected to the material unloading section 72 is arranged at the bottom of one side of the auxiliary material adding box 13, and an export section 82 is arranged at the top of the other side of the auxiliary material adding box 13, and the export section 82 is externally connected to an output barrel 83; the top and bottom of the auxiliary material adding box 13 are also respectively provided with a first belt driver 84 and a second belt driver 85, the first belt driver 84 is close to the introduction section 81, and the second belt driver 85 is close to the export section 82, and a turning belt 86 is installed obliquely between the first belt driver 84 and the second belt driver 85, and a plurality of turning shovels 87 are arranged on the belt surface of the turning belt 86;

[0046] The feeding rack 28 includes a feeding bin 91 and a feeding driver 92 arranged at the output end of the feeding bin 91. The feeding driver 92 is fixed to the side edge of the auxiliary material adding box 13 through a side bracket 93. The output port of the feeding bin 91 leads to the inner cavity of the auxiliary material adding box 13 and is located above the introduction section 81.

[0047] The turning belt 86 is tilted and arranged, and the turning shovel 87 moves along the turning belt 86, thereby turning the materials from bottom to top and lifting the materials from bottom to top. In the process of continuous lifting and turning of the materials from bottom to top, the materials at the bottom are turned up, and with the lifting of the turning belt, the materials are transported from bottom to top to a higher position. In this process, the materials are continuously broken up and mixed, ensuring full contact and uniform mixing between the main materials and the auxiliary materials.

[0048] The feeding rack 28 is responsible for continuously adding auxiliary materials to the auxiliary material adding box 13 in a timely and quantitative manner. Driven by the feeding driver 92, the auxiliary materials in the feeding bin 91 are fed into the auxiliary material adding box 13 at a constant rate and amount, and directly fall into the materials being turned by the turning belt 86 and the turning shovel 87. Due to the continuous turning and lifting action of the turning belt 86 and the turning shovel 87, the auxiliary materials can be relatively evenly distributed in each portion of the main material. This bottom-up turning and lifting process, as well as the timely and quantitative auxiliary material adding method, together ensure that the materials are fully mixed and evenly distributed in the auxiliary material adding box 13.

[0049] In one embodiment, see Figure 1 , Figure 5 , Figure 6 and Figure 7 Based on the contents of the above embodiment, the internal structure of the main material mixing barrel 11 is designed as follows:

[0050] The main body of the secondary mixing barrel 14 is a secondary mixing box 52, a secondary base 51 is provided at the bottom of the secondary mixing box 52, a box cover 53 is provided at the top of the secondary mixing box 52, a material receiving port 54 is provided at the top side edge of the secondary mixing box 52, and the output end of the output barrel 83 is connected to the material receiving port 54; the box body of the secondary mixing box 52 is configured as a concave cylinder shell 101, and the concave cylinder shell 101 constructs the inner cavity of the secondary mixing box 52 into two mixing branch cavities 102, and the secondary mixing mechanism 29 includes mixing support shafts 103 respectively installed in the mixing branch cavities 102 and flip arms 104 installed on the mixing support shafts 103;

[0051] The flip arms 104 are disposed in a plurality and arranged in a spiral pattern along the mixing support shaft 103 , and the flip arms 104 on adjacent mixing support shafts 103 are sequentially staggered with each other.

[0052] The flip arm 104 includes an arc-shaped mounting sleeve 111 installed on the mixing support shaft 103, a supporting bolt 112 arranged on the arc-shaped mounting sleeve 111, and a folding arm plate 113 installed on the supporting bolt 112. A mixing shovel 115 is installed on the plate end of the folding arm plate 113 through the mounting bolt 114, and the shovel body of the mixing shovel 115 faces the spiral inclination direction of the folding arm plate 113.

[0053] The dual-chamber design of the secondary mixing barrel 14 and the spiral arrangement of the flipping arm 104 enable the materials to form complex flow and shear effects during the mixing process, thereby greatly improving the mixing efficiency. At the same time, the inclined design of the mixing shovel 115 also enhances the stirring effect, allowing the materials to reach a uniform mixing state more quickly. The special design of the flipping arm 104 and the mixing shovel 115 allows the materials to be stirred and flipped in all directions during the mixing process, thereby ensuring the uniformity and stability of the mixing. It is particularly suitable for the production and processing of flame retardants where the main materials and auxiliary materials require high mixing uniformity.

[0054] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0055] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
