TECHNICAL FIELD

[0001] The utility model relates to the technical field of diphenyl ethylene production, specifically to the reaction equipment of quantitative catalyst addition. BACKGROUND

[0002] Diphenyl ethylene is an important organic chemical raw material, and has a wide application in the fields of medicine, pesticide, dye, perfume and the like, and its unique chemical structure and property make it become the key component of many high-performance products. With the continuous development of related industries, the demand for diphenyl ethylene is also continuously increasing, and diphenyl ethylene needs to be reacted with raw materials through a reaction equipment in the production process.

[0003] In the production process of diphenyl ethylene, the quantitative addition of catalyst plays a crucial role in the efficiency of the reaction and the quality of the product, and at the same time, the smooth feeding of the reaction raw materials and the catalyst is also a key factor to ensure the continuity of production. At present, the traditional reaction equipment usually has the following problems in the feeding process. On the one hand, the reaction raw materials and the catalyst are prone to be blocked in the feeding funnel due to their physical properties (such as particle size, shape, viscosity, etc.), especially some powdered catalysts, which are more likely to accumulate at the feeding port, resulting in poor feeding. On the other hand, when the feeding funnel is blocked, the existing reaction equipment often lacks effective unblocking means, and manual unblocking not only has low efficiency, but also has safety hazards, which may affect the continuity and stability of production. In view of this, we propose the reaction equipment of quantitative catalyst addition. SUMMARY
