The top and bottom ends of the reactor body are respectively provided with a top cover and a bottom cover. The reactor body is used for the reaction and stirring of polyurethane. The stirring mechanism is arranged inside the reactor body and on the top of the top cover. The stirring mechanism is used for stirring polyurethane and simultaneously driving the downward pressing mechanism. When this technical solution is used, through the setting of the spraying mechanism, the nozzle can rotate when spraying water, and the water can be sprayed onto the inner wall of the reactor body, which is convenient for cleaning. For the above technical solution, although the inner wall of the reactor is cleaned, it is impossible to perform multiple stirring and mixing of the internal materials during use, which is inconvenient during use. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a stainless steel reactor equipment for modified polyurethane production to solve the problems raised in the above background technology. The structure of the utility model is novel. When in use, the conical seat moves upward to cooperate with the ring seat to form a sealed space. During the initial feeding, various materials are preliminarily mixed at the bottom of the conical seat. After the feeding is completed, the conical seat descends, and the materials slide from the side of the conical seat to the stirring column for re-stirring.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions: A stainless steel reactor equipment for modified polyurethane production includes a barrel body. The top of the barrel body is movably installed with a barrel cover. The top of the barrel cover is respectively fixedly installed with a lifting mechanism and a driving motor.

The conical seat is movably installed on the rotating column through the installation hole. The conical seat moves upward to cooperate with the ring seat to form a sealed space. In the early stage of feeding, various materials are preliminarily mixed at the bottom of the conical seat. After the feeding is completed, the conical seat descends, and the materials slide from the side of the conical seat to the stirring column for secondary stirring.

[0009] Further, the stirring rods are distributed on the top of the conical seat, and the stirring columns are distributed on the bottom of the conical seat. The length of the stirring columns is greater than the length of the stirring rods.

[0010] Further, a ring seat is fixed on the inner wall of the barrel body. The ring seat is made of rubber material, and the bottom of the ring seat movably cooperates with the conical seat.

The electric heating wire is energized to generate heat, and the heat is transferred to the inside of the barrel body 1 to maintain the required flowing temperature for the internal materials, avoiding the inconvenience caused by the solidification of the internal materials.

[0013] Advantages of the present utility model:

[0014] In the present utility model, when in use, the conical seat moves upward to cooperate with the ring seat to form a sealed space. In the early stage of feeding, various materials are preliminarily mixed at the bottom of the conical seat. After the feeding is completed, the conical seat descends, and the materials slide from the side of the conical seat to the stirring column for secondary stirring.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a stainless steel reactor device for the production of modified polyurethane, including a barrel body 1, a barrel cover 2 is movably installed at the top of the barrel body 1, a lifting mechanism 4 and a driving motor 5 are respectively fixedly installed at the top of the barrel cover 2, a support ring 11 is welded at the top of the barrel body 1, a fixing ring 12 is welded at one end of the barrel cover 2, a fixing bolt 3 is rotatably installed between the support ring 11 and the fixing ring 12, a circulation pipe 7 is fixed on the side of the barrel body 1, a pump body 8 is fixedly installed on the circulation pipe 7, a discharge pipe 10 and a support column 9 are respectively fixedly installed at the bottom of the barrel body 1, a control valve is fixedly installed on the discharge pipe 10, and later, under the stirring of the stirring column 19, the material is pushed to be discharged downward from the discharge pipe 10, which is convenient for later discharge use.

[0024] In this embodiment, a rotating column 13 is installed on the driving motor 5. A stirring rod 14 and a stirring column 19 are respectively welded on the rotating column 13. A movable column 15 is fixedly installed on the lifting mechanism 4. One end of the movable column 15 is fixed with a conical seat 16. An installation hole is opened on the conical seat 16. The conical seat 16 is movably installed on the rotating column 13 through the installation hole. The stirring rods 14 are distributed on the top of the conical seat 16, and the stirring columns 19 are distributed on the bottom of the conical seat 16. The length of the stirring column 19 is greater than that of the stirring rod 14. The lifting mechanism 4 is a linear reciprocating electric push rod. The lifting mechanism 4 pushes the conical seat 16 up and down to control the stirring and mixing of materials.

[0025] In this embodiment, a ring seat 17 is fixed on the inner wall of the barrel body 1. The ring seat 17 is made of rubber. The bottom of the ring seat 17 is movably matched with the conical seat 16. A dispersion plate 18 is fixedly installed inside the circulation pipe 7. An opening 20 is opened on the dispersion plate 18. A heating and heat preservation plate is fixedly installed inside the barrel body 1. An electric heating wire is fixedly installed inside the heating and heat preservation plate. The electric heating wire is energized to generate heat, and the heat is transferred to the inside of the barrel body 1 to maintain the required flowing temperature of the internal materials, avoiding the inconvenience caused by the solidification of the internal materials.

[0026] When the device is in use, the lifting mechanism 4 is started to drive the movable column 15 to move upward. The movable column 15 drives the conical seat 16 to contact the ring seat 17 to form a sealed space. The material is injected into the inside of the barrel body 1 through the feed pipe 6. The material stays on the top of the conical seat 16. The driving motor 5 is started to drive the stirring rod 14 on the rotating column 13 to rotate, and preliminary stirring is completed while feeding in the early stage.

After the conical seat 16 descends, the space on the side of the conical seat 16 is opened, and the material slides along the inclined surface of the conical seat 16 to the side. The material slowly flows downward through the gap between the conical seat 16 and the barrel body 1. When the material flows downward, the stirring column 19 rotates again to stir the falling material again. After long-term stirring by the stirring column 19, the pump body 8 on the circulation pipe 7 is started to pump the material at the bottom upward. The liquid moves through the dispersion plate 18 after being pressurized, and the material is discharged through the opening 20 under extrusion. The materials are extruded and mixed again under extrusion. The material falls onto the conical seat 16 again and slowly falls for stirring and mixing, and is discharged through the discharge pipe 10 after stirring and mixing.
