Description

Technical Field

[0001] This utility model relates to the technical field of decabromodiphenyl ethane production equipment, and in particular to a mixing machine for decabromodiphenyl ethane. Background Technology

[0002] Decabromodiphenyl ethane is a highly efficient additive flame retardant with excellent thermal stability and extremely high bromine content. It also exhibits strong UV resistance, low toxicity, and low exudation. It is widely used in styrene-based polymers, engineering thermoplastics, thermosetting plastics, wire sheathing, insulators, and elastomers, and is particularly suitable for flame retardancy in electronic and electrical products.

[0003] In the production process of decabromodiphenyl ethane, a mixer is needed to mix the materials (diphenyl ethane, bromine, etc.). In existing technology, a double helix is ​​usually used to stir the materials and convey them onto a mesh belt for subsequent filtration and dewatering. However, due to the natural inclination angle of the double helix, a downward force is exerted on the materials when they are distributed to both sides, resulting in a thicker distribution of the materials in the middle and thinner distribution on the mesh belt. This makes it impossible to convey the materials evenly. Moreover, because the materials themselves are relatively large, the mesh belt is easily damaged after long-term operation, affecting the filtration effect, reducing production efficiency, and failing to guarantee the quality of the product. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a mixing machine for decabromodiphenyl ethane that can achieve uniform mixing and conveying while improving production efficiency and ensuring product quality.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A mixer for decabromodiphenyl ethane includes a mounting frame, a double helix, a conveyor belt, and a stirrer. The mounting frame is disposed above the conveyor belt. The double helix is ​​rotatably mounted within the mounting frame to convey the mixture. The stirrer includes a rotating shaft and multiple sets of stirring blade assemblies. The rotating shaft is rotatably mounted within the mounting frame. Each set of stirring blade assemblies is spaced apart along the axial direction of the rotating shaft. Each stirring blade assembly includes multiple blades distributed radially around the outer periphery of the rotating shaft. Each blade includes a body and two side wings, with the two side wings disposed on either side of the end of the body away from the rotating shaft.

[0007] Furthermore, the number of blades in each set of the mixing blade assembly is 3 to 6.

[0008] Furthermore, the number of blades is even, and two opposite blades are centrally symmetrical about the rotation axis.

[0009] Furthermore, the blade has an arc-shaped portion at its end, and the centers of the multiple arc-shaped portions are the same, which is the center of the rotation axis.

[0010] Furthermore, the mixing machine for decabromodiphenyl ethane also includes a turning device, which includes a fixed shaft and loosening components. The fixed shaft is installed in the mounting frame and located on one side of the rotating shaft. The loosening components are distributed at intervals along the axial direction of the fixed shaft. The loosening components are used to turn over and loosen the mixture.

[0011] Furthermore, the axial directions of the double helix, the fixed shaft, and the rotating shaft are all parallel to each other.

[0012] Furthermore, the fixed shaft is fixedly installed inside the mounting frame, and the bulk material component abuts against the mesh belt to loosen and tumble the mixture.

[0013] Furthermore, the mixing machine for decabromodiphenyl ethane also includes a support frame, which is located on one side of the mesh belt, and the mounting bracket is fixedly installed on the support frame.

[0014] Furthermore, the mixer for decabromodiphenyl ethane also includes an adjusting bolt, one end of which is connected to the mounting frame and the other end to the bracket, and the mounting frame can move up and down via the adjusting bolt.

[0015] Furthermore, the mixer for decabromodiphenyl ethane also includes a feeding hopper, which is mounted on the support and located above the double helix.

[0016] Compared to existing technologies, this utility model's mixing machine for decabromodiphenyl ethane includes a mounting frame, a double helix, a mesh belt, and a stirrer. The mounting frame is positioned above the mesh belt, and the double helix is ​​rotatably mounted within the mounting frame to convey the mixture. The stirrer includes a rotating shaft and multiple sets of stirring blade assemblies. The rotating shaft is rotatably mounted within the mounting frame, and each set of stirring blade assemblies is spaced apart along the axial direction of the rotating shaft. Each stirring blade assembly includes multiple blades distributed radially around the outer periphery of the rotating shaft. Each blade includes a body and two side wings, located on either side of the body at the end furthest from the rotating shaft. In this application, after the stirrer agitates the mixture, the side wings flatten the mixture between the blades and the mesh belt. The mixture then enters the filter press zone, ensuring that the entire material surface is flattened, achieving uniform distribution of the mixture. This prevents damage to the mesh belt after prolonged operation, maintains the filter press effect, extends the service life of the mesh belt, increases production efficiency, and guarantees product quality.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Figures 1-3The present invention relates to a mixer for decabromodiphenyl ethane, comprising a mounting frame 10, a double helix 30, a turner 40, a mixer 50, a support plate 60, a bracket 70, adjusting bolts 80, and a feeding hopper 90.

[0025] In this embodiment:

[0026] The mounting frame 10 includes a first mounting frame 11 and a second mounting frame 12. The first mounting frame 11 is used to mount the double helix 30, and the second mounting frame 12 is used to mount the material turner 40 and the agitator 50. The first mounting frame 11 and the second mounting frame 12 are both set above the mesh belt 20. The material turner 40 and the double helix 30 are separated by the first mounting frame 11 and the second mounting frame 12. The above arrangement can separate the process of mixing, conveying and uniformly distributing materials, and prevent the mixed materials from splashing directly onto the material turner 40 and the agitator 50 during the conveying process, which would affect the uniform distribution of the subsequent mixed materials.

[0027] The mesh belt 20 is installed on the frame 100 and is used to transport the mixture to the filter press zone for subsequent dewatering.

[0028] The double helix 30 is rotatably installed in the first mounting frame 11 for conveying decabromodiphenyl ethane. Due to the natural inclination angle of the double helix, when distributing the material to both sides, it will give the material layer a downward component force, resulting in the material layer being thicker in the middle and thinner at both sides. However, compared to conveying decabromodiphenyl ethane from one end to the other, because the path of the double helix 30 is shorter, the distribution of thickness difference is relatively small, making it easier to uniformly distribute the material later.

[0029] The material turner 40 includes a fixed shaft 41 and material distribution components 42. The fixed shaft 41 is fixedly installed inside the second mounting bracket 12. The material distribution components 42 are spaced apart on the fixed shaft 41 along its axial direction. The material distribution components 42 abut against the mesh belt 20 to turn and loosen the mixture, causing larger particles to become smaller particles. In this embodiment, the axial direction of the fixed shaft 41 is parallel to the axial direction of the double helix 30. The material distribution components 42 are plows or rakes. Utilizing their structural characteristics, the plows or rakes abut against the mesh belt 20 to turn and loosen the mixture. No drive component is needed to rotate them for turning and loosening, making them convenient, quick, and with lower production costs.

[0030] The agitator 50 includes a rotating shaft 51 and multiple sets of mixing blade assemblies 52. The rotating shaft 51 is rotatably mounted within the second mounting bracket 12. In this embodiment, the axial direction of the rotating shaft 51 is parallel to the axial direction of the fixed shaft 41, and the rotating shaft 51 rotates away from the double helix 30. In a preferred embodiment, the central axes of the double helix 30, the fixed shaft 41, and the rotating shaft 51 are on the same horizontal plane, ensuring a smooth transition between these mixing methods and preventing material contamination or retention, thus promoting uniform material distribution.

[0031] The mixing blade assembly 52 includes multiple blades 521, which are distributed radially around the outer periphery of the rotating shaft 51. Each blade 521 includes a body 5211 and two side wings 5212. The two side wings 5212 are located on both sides of the end of the body 5211 away from the rotating shaft 51, further agitating the mixture loosened by the turner 40. The side wings 5212 can also flatten the mixture between the blades 521 and the mesh belt 20, thereby ensuring that the entire material surface is leveled, achieving uniform distribution of the mixture. This prevents damage to the mesh belt 20 after long-term operation, does not affect the filtration effect, extends the service life of the mesh belt 20, improves production efficiency, and ensures product quality. In this embodiment, the number of blades 521 in each mixing blade assembly 52 is 3 to 6. Preferably, the number of blades 521 is even, and two opposite blades 521 are symmetrical about the center of the rotation axis 51. The arrangement of the blades 521 in this design is symmetrical and uniform to ensure that the mixing operation is balanced and reliable. The blades 521 have the same shape and the same mass. During processing, tooling is used with the center as the positioning reference to ensure that the processing allowance of each part is symmetrical and uniform.

[0032] In a preferred embodiment, the end of the blade 521 is provided with an arc-shaped portion 5213, and the centers of the multiple arc-shaped portions 5213 are the same, which is the center of the rotating shaft 51.

[0033] The support plate 60 is mounted on the frame 100 and located below the mesh belt 20. It can counteract the downward stress of the mixed material and prevent the mesh belt 20 from deforming and making the fabric too thick. In this embodiment, the support plate 60 is only set below the mesh belt 20 located below the double helix 30, the turner 40, and the agitator 50. It is not necessary to set the support plate 60 under the entire mesh belt 20, which can reduce production costs.

[0034] The bracket 70 is located on one side of the mesh belt 20, and the mounting bracket 10 is fixedly installed on the bracket 70.

[0035] One end of the adjusting bolt 80 is connected to the mounting frame 10, and the other end is connected to the bracket 70. The adjusting bolt 80 can adjust the height of the mounting frame 10, thereby adjusting the distance between the double helix 30, the agitator 50 and the mesh belt 20 to meet different mixing and conveying requirements.

[0036] The feeding bin 90 is mounted on the bracket 70 and located above the double helix 30, and is used to feed and convey materials to the double helix 30.

[0037] In use, the mixed material is fed into the double helix 30 through the feeding hopper 90 and conveyed. The mixed material is spread out from the middle to both sides. The loose material parts 42 abut against the mesh belt 20 to loosen and turn the mixed material, so that the larger mixed material particles become smaller mixed material particles. When the loose mixed material passes through the agitator 50, the blades 521 on the rotating shaft 51 further agitate the mixed material, and the side wings 5212 flatten the mixed material between the blades 521 and the mesh belt 20. The mixed material then enters the filter press zone, ensuring that the entire material surface is leveled, achieving uniform distribution of the mixed material. After long-term operation, it will not cause damage to the mesh belt 20, will not affect the filter press effect, improve the service life of the mesh belt 20, improve production efficiency, and ensure product quality.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
