Description

Technical Field

[0001] This utility model relates to the technical field of decabromodiphenyl ethane production equipment, and in particular to a bulk material device for decabromodiphenyl ethane production. 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] Currently, decabromodiphenyl ethane is mostly synthesized using the excess bromine method. Before packaging the finished product, the material is sieved using a bulk material handling device to crush coarse particles into finer particles, ultimately obtaining a high-purity powder. Existing technology typically uses a stirring shaft to agitate and crush the material in a funnel. The bottom of the funnel usually has an opening for material discharge. This device has a relatively simple structure and suffers from uneven mixing, resulting in the presence of coarse particles in the final product. This compromises product quality and affects its flame-retardant properties in the electronics and electrical appliance industries. Utility Model Content

[0022] 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.

[0023] Figures 1-5 The present invention relates to a bulk material handling device for the production of decabromodiphenyl ethane, comprising a base 10, a mounting frame 20, a first storage silo 30, a first drive assembly 40, a stirrer 50, a second storage silo 60, a second drive assembly 70, a chain 80, and a disperser 90.

[0024] In this embodiment:

[0025] The base 10 includes a discharge bin 11 and a support frame 12. Multiple discharge bins 11 are arranged outside the second storage bin 60 along the circumferential direction of the second storage bin 60, and the support frame 12 is vertically installed on the discharge bins 11.

[0026] The mounting bracket 20 is horizontally mounted on the support frame 12 and located above the second storage bin 60. The mounting bracket 20 is provided with a material discharge port 21. In this embodiment, multiple mounting brackets 20 are arranged outside the first storage bin 30 along the circumferential direction of the first storage bin 30.

[0027] The first storage bin 30 is installed on the mounting frame 20. The side wall of the first storage bin 30 is provided with a first discharge port 31, which is connected to the discharge port 21.

[0028] The first drive assembly 40 is disposed in the first storage bin 30. The first drive assembly 40 includes a first motor 41 and a first transmission shaft 42. The first transmission shaft 42 is mounted on the shaft of the first motor 41, and the agitator 50 is mounted on the first transmission shaft 42. The first motor 41 drives the first transmission shaft 42 to rotate and drives the agitator 50 to rotate, so as to initially disperse the material.

[0029] The second storage bin 60 is mounted on the base 10. The side wall of the second storage bin 60 is provided with a second discharge port 61, which is connected to the discharge bin 11. In this embodiment, the inner walls of the first storage bin 30 and the second storage bin 60 are smoothly polished (Ra≤1.6μm) or processed with anti-slip textures. The former can reduce material adhesion, while the latter can enhance friction to drive the material to rotate.

[0030] The second drive assembly 70 is disposed inside the second storage silo 60. The second drive assembly 70 includes a second motor 71 and a second transmission shaft 72. The second transmission shaft 72 is mounted on the shaft of the second motor 71, and the disperser 90 is mounted on the second transmission shaft 72. The second motor 71 drives the second transmission shaft 72 to rotate and drives the disperser 90 to rotate, so as to perform secondary dispersion of materials.

[0031] A chain 80 is installed inside the second storage bin 60. Material at the discharge port 21 falls into the second storage bin 60 via the chain 80. The scraping action of the chain 80 breaks the adhesion between material particles, preventing clumping and ensuring product quality and its subsequent flame-retardant effect. In this embodiment, there are multiple chains 80, which are radially distributed within the second storage bin 60 along its radial direction.

[0032] In use, this application first disperses the material in the first storage silo 30 using the first drive assembly 40 and the agitator 50. The material then falls into the second storage silo 60 through the first discharge port 31, the drop port 21, and the chain 80. Next, the material in the second storage silo 60 is dispersed a second time using the second drive assembly 70 and the disperser 90. Finally, the finished product enters the discharge silo 11 through the second discharge port 61. In this application, the material undergoes two dispersion processes, ensuring uniform mixing, guaranteeing product quality, and enhancing its subsequent flame-retardant effect.

[0033] 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.
