Convenient-to-maintain large-capacity quick-opening reaction kettle

Abstract

The invention discloses a convenient-to-maintain large-capacity quick-opening reaction kettle. The convenient-to-maintain large-capacity quick-opening reaction kettle comprises a kettle body, a kettle cover and a rotary shaft, wherein the rotary shaft is internally provided with a stirring shaft; a plurality of storage grooves are formed in a side wall of the stirring shaft; the stirring shaft is in rotary connection with stirring rods at the storage grooves; trapezoid holes are formed among inner cavities of the storage grooves and the stirring shaft; a push-pull rod is in sliding connection with the inside of the stirring shaft through a plurality of linear bearings; the upper end of the push-pull rod stretches out of the stirring shaft and is fixedly connected with a push baffle plate; the push-pull rod is in rotary connection with connecting rods with the quantity the same as that of the stirring rods; the other ends of the connecting rods are in rotary connection with the stirring rods; the upper end of the side wall of the stirring shaft is further fixedly connected with a transmission plate; a fastening screw disc also sleeves the stirring shaft between the transmission plate and the push baffle plate. According to the convenient-to-maintain large-capacity quick-opening reaction kettle, the stirring shaft can be directly pulled out, so that replacement and maintenance are convenient to carry out; meanwhile, the stirring shaft is not stopped by the kettle body and convenient-to-open hinge type connection can be adopted; the volume of the kettle body can be improved and the capacity is increased.

Description

technical field [0001] The invention relates to a chemical reaction kettle, in particular to a large-capacity quick-opening reaction kettle with convenient maintenance. Background technique [0002] Reactor is a kind of chemical equipment widely used in the chemical industry. It is mainly composed of a kettle body, a kettle cover and a hot oil tank. Nowadays, there are two commonly used connection structures between the kettle body and the kettle cover of the reactor. One is a self-mixing type The hinge connection of the reactor is a threaded sleeve connection for the stirred reactor. The hinged reactor is very convenient to open the cover, but because it has no stirring rod, it is mainly used in places that do not require high mixing of materials. Relatively speaking, the other is the most common stirred reactor. The lid of the kettle is equipped with a stirring assembly, which accelerates the mixing of the internal materials through the rotation of the stirring rod, and th...

[0002] Reactor is a kind of chemical equipment widely used in the chemical industry. It is mainly composed of a kettle body, a kettle cover and a hot oil tank. Nowadays, there are two commonly used connection structures between the kettle body and the kettle cover of the reactor. One is a self-mixing type The hinge connection of the reactor is a threaded sleeve connection for the stirred reactor. The hinged reactor is very convenient to open the cover, but because it has no stirring rod, it is mainly used in places that do not require high mixing of materials. Relatively speaking, the other is the most common stirred reactor. The lid of the kettle is equipped with a stirring assembly, which accelerates the mixing of the internal materials through the rotation of the stirring rod, and the effect is remarkable. However, because the stirring rod is too long If it cannot be opened by flipping the lid, the current stirring reactor is either a small-capacity flip-top type, which can be flipped smoothly by reducing the length of the stirring rod and the volume of the kettle body, or it is a large-capacity direct-opening type, that is, the above-mentioned threaded sleeve It is very troublesome to turn the kettle lid and lift it to separate the two when opening the lid. In addition, because the reactor is mostly used for the mixing and stirring reaction of chemical raw materials, after long-term use, due to the erosion of chemical raw materials, the stirring rod and the stirring blades will inevitably be damaged There is a certain degree of wear and tear. It is very troublesome to replace the stirring blades of today's reactors. It is necessary to disassemble and reinstall the closely connected stirring shaft and the lid of the kettle. The technical requirements are high. Advantages of the new reactor is necessary
