Description

Technical Field

[0001] The utility model relates to the technical field of polyester material reactors, in particular to a multifunctional reactor for polyester materials. Background Art

[0002] Polyester material is a type of polymer compound whose molecular structure contains multiple ester bonds. Polyester material is usually formed by polymerization reaction of polyester monomers. The selection of polyester monomers and reaction conditions will affect the performance and use of the material. Polyester material has excellent chemical corrosion resistance, wear resistance and excellent electrical insulation properties. Therefore, it is widely used in various industries. When stirring polyurethane materials, a reactor is usually required to stir them. A reactor is a container used for chemical reactions, usually made of corrosion-resistant materials such as glass, stainless steel or alloys. The reactor can carry out chemical reactions under controlled conditions, usually including heating, cooling, stirring, pressure control and other functions.

[0003] Existing reactors for stirring polyester materials usually consist of a reactor body and a stirring mechanism. The stirring mechanism is used to stir the materials in the reactor to make them evenly mixed. However, these reactors are basically general-purpose reactors. In actual use, due to the high viscosity of polyester materials, the stirring blades will slowly corrode when stirred in the reactor, resulting in wear of the stirring blades, causing an imbalance in the weight of the stirring blades and the stirring shaft, and increasing the burden and wear rate of the motor. Therefore, the current general-purpose reactors are not specifically used for the production of polyester materials.

[0004] In view of this, it is indeed necessary to provide a reactor specifically for polyester material production that solves the above problems. Utility Model Content

The reactor body is made of austenitic duplex stainless steel S22053. The stirring mechanism comprises a motor, the lower end of which is connected to a reducer, which is disposed on the reactor body. The output shaft of the reducer passes through the reactor body and is connected to a stirring shaft via a connecting mechanism. The outer wall of the stirring shaft is provided with stirring blades, and the outer wall of the reactor body is provided with a heating component.

[0008] The kettle body includes a cylinder, an upper head and a lower head. A water inlet pipe is provided on one side of the cylinder, a feed port is provided on the upper head, and a discharge pipe is provided on the lower head.

[0011] Furthermore, the upper end of the transmission member is fixedly connected to a spring, and the upper end of the spring is fixedly connected to the transmission groove.

[0012] Furthermore, the connecting mechanism also includes a sealing sleeve mounted on the outside of the connecting piece, the sealing sleeve is provided with a plurality of through holes passing through the upper connecting head and the lower connecting head, the through holes are provided with connecting bolts, and the connecting bolts are threadedly connected with nuts.

[0028] In the present invention, the stirring shaft 4 is connected to the output shaft of the reducer 22 through the connecting mechanism 3 to realize power transmission, and the stirring shaft 4 and the stirring blade 5 can be taken out for replacement after the stirring blade 5 is worn, so as to avoid affecting the motor 21 and the reducer 22. In this embodiment, the reactor is connected to the PLC frequency conversion control system, and the reactor body 1 is made of austenitic duplex stainless steel S22053 material, which has strong corrosion resistance and is suitable for the reaction of polyester materials. The inner layer thickness corroded each year is only 0.01 mm / year, while the inner layer thickness of the conventional stainless steel 304 reactor is corroded each year at 0.1 mm / year.

[0029] Furthermore, in this embodiment, the connecting mechanism 3 includes an upper connecting head 31, a lower connecting head 32 and a connecting member 33.

A slot that cooperates with the transmission member 312 is provided on the lower connecting head 32. When the upper connecting head 31 rotates, the transmission member 312 drives the slot and the lower connecting head 32 to rotate, realizing power connection, and further transmission is performed by setting the connecting member 33 to prevent the transmission member 312 from being broken due to excessive force.

[0030] Furthermore, in this embodiment, the connecting member 33 includes a first connecting portion 331 and a second connecting portion 332.
