[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] like Figures 1 to 6 As shown, the utility model provides a double-layer glass reactor stirring sealing structure, comprising a reactor body 10 and a reactor cover 20 installed above the reactor body 10, and a motor seat 30 is further arranged above the reactor cover 20;

[0037] The kettle cover 20 and the motor base 30 are respectively provided with a channel 1 21 and a channel 2 31 which are connected to each other. A sealing top plate 32 is provided at the bottom of the channel 2 31, and a sealing bottom plate 22 is provided at the top of the inner cavity of the kettle cover 20.

[0038] A multi-layer composite sealing structure 40 for additional sealing is disposed above the sealing bottom plate 22 , and two sealing end plates 50 are disposed above the multi-layer composite sealing structure 40 , with a rubber layer 60 sandwiched between the two sealing end plates 50 ;

[0039] A rotating shaft 70 is provided on the top of the motor base 30. The rotating shaft 70 penetrates the sealing top plate 32, the sealing end plate 50, the rubber layer 60, the multi-layer composite sealing structure 40 and the sealing bottom plate 22 from top to bottom and extends to the inner cavity of the kettle body 10. A spring sealing structure 80 for providing elastic sealing is provided between the sealing top plate 32 and the sealing end plate 50.

[0040] Through the coordinated use of the multi-layer composite sealing structure 40 and the spring sealing structure 80, the structure can enhance the adaptability and durability of the reactor under variable working conditions and extend the service life of the equipment.

[0041] Among them, the upper flange 11 at the top of the kettle body 10 and the lower flange 23 at the bottom of the kettle cover 20 are tightly connected by bolts and nuts, and the upper flange 24 at the top of the kettle cover 20 and the lower flange 2 33 at the bottom of the motor base 30 are tightly connected by bolts and nuts.

[0042] The tight connection of bolts and nuts can ensure the sealing between the kettle body 10 and the kettle cover 20, as well as between the kettle cover 20 and the motor base 30. This tight connection can effectively prevent leakage of the medium and ensure the sealing performance of the reactor. The connection method of bolts and nuts makes it easy to disassemble and install the kettle body 10, the kettle cover 20 and the motor base 30, which facilitates the maintenance and cleaning of the equipment and reduces the maintenance and repair time.

[0043] Among them, a plurality of positioning screws 25 are arranged at the bottom of the sealing bottom plate 22 , and the top threads of the positioning screws 25 penetrate the sealing bottom plate 22 and are connected with the top threads of the inner cavity of the kettle cover 20 , and the sealing top plate 32 is clamped and fixed by the kettle cover 20 and the motor seat 30 .

[0044] By setting the positioning screw 25, it can ensure that the positions of the sealing bottom plate 22 and the kettle cover 20 are relatively fixed, thereby preventing the sealing bottom plate 22 from being displaced or loosened during the stirring process; at the same time, the sealing top plate 32 is clamped and fixed by the kettle cover 20 and the motor seat 30, thereby ensuring the stability of the sealing top plate 32, keeping the position of the sealing top plate 32 stable, and preventing it from being loosened or falling off.

[0045] The multi-layer composite sealing structure 40 includes an asbestos layer 41 , a polytetrafluoroethylene layer 42 , a graphite layer 43 and a ceramic layer 44 which are arranged in sequence from bottom to top.

[0046] The multi-layer composite sealing structure 40 can improve the sealing performance. The asbestos layer 41 is resistant to high temperature and corrosion. The polytetrafluoroethylene layer 42 has good chemical corrosion resistance. The graphite layer 43 has good sealing performance and wear resistance. The ceramic layer 44 has good wear resistance and high temperature resistance. Through the stacking of these materials, a solid defense line is formed, which effectively prevents the leakage of the medium and the invasion of external pollutants.

[0047] The outer ring of the rotating shaft 70 is provided with an annular protrusion 71 , and the upper and lower sides of the annular protrusion 71 are provided with sealing grooves 72 . The adjacent side of the two sealing end plates 50 is provided with a sealing strip 51 , and the sealing strip 51 is connected to the sealing groove 72 .

[0048] Through the connection between the sealing strip 51 and the sealing groove 72, the double-layer glass reactor stirring sealing structure can provide better sealing and protective performance, while facilitating maintenance and replacement, extending the service life of the equipment, and protecting the safety of operators; the setting of the annular protrusion 71 can increase the contact area of ​​the seal and improve the sealing performance.

[0049] The spring sealing structure 80 includes a plurality of spring expanders 81 . The spring expanders 81 are arranged in a circle around the rotating shaft 70 . Sealing gaskets 82 are respectively provided at both ends of the spring expanders 81 .

[0050] By setting the spring expansion joint 81 and the sealing gasket 82, the double-layer glass reactor stirring sealing structure can provide reliable sealing performance. The surrounding arrangement of the spring expansion joint 81 can provide uniform pressure to ensure the tightness of the seal. In addition, the design of the spring expansion joint 81 and the sealing gasket 82 makes maintenance and replacement more convenient. When there is a problem with the spring expansion joint 81 or the sealing gasket 82, it only needs to be removed from the rotating shaft 70 and then replaced with a new spring expansion joint 81 or the sealing gasket 82.

[0051] The working principle and use process of this utility model:

[0052] The substance to be reacted is placed in the kettle body 10, and then the kettle cover 20 is installed on the kettle body 10;

[0053] The tight connection between the bolts and nuts ensures the sealing between the kettle body 10 and the kettle cover 20 and between the kettle cover 20 and the motor base 30. This tight connection can effectively prevent the leakage of the medium and ensure the sealing performance of the reactor.

[0054] The motor is started, and the motor drives the stirrer to stir through the rotating shaft 70. The rotating shaft 70 passes through the sealing top plate 32, the sealing end plate 50, the rubber layer 60, the multi-layer composite sealing structure 40 and the sealing bottom plate 22 from the top of the motor base 30, and extends to the inner cavity of the kettle body 10. The stirring action of the stirrer fully mixes and stirs the reaction materials;

[0055] The multi-layer composite sealing structure 40 and the spring sealing structure 80 are used together to ensure the reliability and stability of the sealing performance and prevent medium leakage and contamination;

[0056] After the reaction is finished, the motor is stopped and the material in the reactor is taken out.
