Dust collection reaction system with combined stirring paddle

Abstract

The invention discloses a dust collection reaction system with a combined stirring paddle. The dust collection reaction system comprises a dust collection device and a reaction still, wherein a feeding opening is formed in the top of the reaction still; the dust collection device comprises a dust hood positioned above the feeding opening and a suction device; the dust hood and the suction device are connected through a dust collection pipe; the suction device comprises a suction pump in which a piston is arranged; the piston is connected with a piston rod; one end of the piston rod extends out of the rear end of the suction pump and is connected with a screw rod motor; a screw rod of the screw rod motor extends into the sleeve-shaped piston rod and is in threaded connection with the piston rod; a stirring main shaft is arranged in the reaction still; the upper end of the stirring main shaft extends out of the reaction still; the stirring paddle is arranged on the stirring main shaft, and comprises a helix ribbon type stirring vane and turbine type stirring vanes. Through the adoption of the system, in a feeding process, powdery raw materials floating at the feeding opening can be sucked, so that flying of the powdery raw materials is avoided, and body health of workers and safety production of factories are ensured.

Description

technical field [0001] The invention relates to the field of composite material processing, in particular to a dust suction reaction system with a combined stirring paddle. Background technique [0002] Reactor is a comprehensive reaction vessel, which is widely used in petroleum, chemical, rubber, pesticide, dye, medicine, food and other production users and various scientific research and experimental projects. Reactor is widely used in petroleum, chemical, rubber, pesticide, pharmaceutical , food and other fields, it uses the stirring device to stir and mix the materials, so that the materials in the reactor can be distributed more evenly to accelerate the material reaction, and ensure that the materials in the reactor can carry out the predetermined chemical reaction according to the predetermined reaction conditions. In the field of processing, it is necessary to pour each raw material into the reactor for stirring and mixing when feeding, because the materials are all ...

[0002] Reactor is a comprehensive reaction vessel, which is widely used in petroleum, chemical, rubber, pesticide, dye, medicine, food and other production users and various scientific research and experimental projects. Reactor is widely used in petroleum, chemical, rubber, pesticide, pharmaceutical , food and other fields, it uses the stirring device to stir and mix the materials, so that the materials in the reactor can be distributed more evenly to accelerate the material reaction, and ensure that the materials in the reactor can carry out the predetermined chemical reaction according to the predetermined reaction conditions. In the field of processing, it is necessary to pour each raw material into the reactor for stirring and mixing when feeding, because the materials are all in the form of powder, and a large amount of flying dust will be generated during the feeding process. During the stirring process, because the stirring paddle cannot work stably, it will also A large amount of dust is produced. These chemical dusts are extremely harmful to the health of workers and the safety of the factory. The existing technology mostly adopts the method of adding exhaust fans around the factory building to remove dust. This method cannot achieve a good dust removal effect.
